TAPPED OUT? LEAD IN THE DISTRICT OF COLUMBIA AND THE PROVIDING OF SAFE
DRINKING WATER
----------
THURSDAY, JULY 22, 2004
House of Representatives,
Committee on Energy and Commerce,
Subcommittee on Environment
and Hazardous Materials,
Washington, DC.
The subcommittee met, pursuant to notice, at 9:30 a.m., in
room 2322, Rayburn House Office Building, Hon. Paul E. Gillmor
(chairman) presiding.
Members present: Representatives Gillmor, Bass, Issa,
Otter, Barton (ex officio), Solis, Schakowsky, Stupak, and
Green.
Staff present: Mark W. Menezes, chief counsel; Tom
Hassenboehler, counsel; Jerry Couri, policy coordinator;
William Harvard, legislative clerk; Dick Frandsen, minority
counsel; Bettina Poirier, minority counsel; and Jeff Donofrio,
research assistant.
Mr. Gillmor. The committee will come to order, and the
chair will recognize himself for the purpose of an opening
statement.
In late January of this year, local press in Washington
began reporting that the DC Water and Sewer Authority had found
elevated lead levels in the drinking water of more than 4,000
homes in Washington, DC during testing done in 2003. This news,
in and of itself, would have been cause for concern, except
these reports signaled that not only was WASA, once again,
having problems complying with Federal advisory levels, but it
was now the only large municipal drinking water utility whose
chronic problems could not be remedied.
Between that time and now, several congressional committees
have tried to understand the situation and the Safe Drinking
Water Act as it applies to lead levels, and I applaud them for
their earnestness. However, I am afraid that in their rush to
show outrage and interest in drinking water standards they fail
to obtain any meaningful answers to the plight of those people
who live and work in DC.
I believe that to understand the issues in DC, you have to
understand the Federal rules for lead in drinking water. To
appreciate these regulations, you have to comprehend the Safe
Drinking Water Act. And to completely take hold of the Safe
Drinking Water Act, you have to understand public health and
the things that go into protecting it from the source.
As the subcommittee with sole jurisdiction over the
drinking water act, and one that is charged by the House of
Representatives with defending public health, I wanted to
ensure that any work done by our panel be thoughtful,
comprehensive, deliberate, substantive, and meaningful.
On March 15 of this year, I began an inquiry into the
matter by sending letters to WASA and the U.S. EPA, calling on
the government accountability office to do a full study of the
matter, and asking staff to research and understand the
intricacies of the problem and to examine places that needed
followup.
Today's hearing gives all of us a chance to digest many of
the things this inquiry has uncovered, and I am glad that this
committee resisted style for substance. First, it talks about
the many places where the DC situation went wrong, what is
being done to make it right, and the lessons learned along the
way.
Second, it allows us to look at issues within the lead and
copper rule, including public notification and how other
communities have used this rule to handle elevated amounts of
lead in their drinking water.
Finally, this hearing will allow our panel to delve into
the issue of providing safe drinking water and how our Nation's
infrastructure is presenting both a problem and a solution for
this future need.
Some have tried to use the plight of DC to argue for an
overhaul of existing lead standards, suggesting that the
Federal standard for lead in drinking water is too high and
should be tightened. As the father of three young boys, I am
well aware of the dangers lead presents to young minds.
However, as we enter this hearing, I am not convinced that this
situation demands that we need to make drinking water utilities
face tougher standards.
Rather, I believe that we need people to live up to the
standards as written. I believe what has happened to the
drinking water in our Nation's capital is that people have
failed them, not the laws. And that being said, we also need to
be sure that the drinking water problems in DC are not a
national phenomenon. I do not believe--but our witnesses will
help us begin to understand the efforts of 54,000 community
water systems to provide about 90 percent of Americans with
their tap water.
Two years ago, our subcommittee heard testimony from many
of the water utilities that the greatest challenges facing
community water systems today is aging pipes and other water
infrastructure. We need to ask if this priority has changed,
and, if it has changed, how much. In addition, as authorizers,
we need a better command of the financial needs of the drinking
water State revolving loan fund.
Our subcommittee should not let the House Appropriations
Committee shortchange the important work of SRF simply because
they don't understand it.
And before I conclude my remarks and recognize the
gentlelady from California, Ms. Solis, for opening remarks on
her own, I want to thank the witnesses for their time today. I
know some of these witnesses are getting very familiar with
each other, probably more familiar than some of them would
like. But each of them provides invaluable insight into the
problems we are confronting today, and I want them to know we
appreciate the sacrifice you are making to be with us.
And with that, I yield back the balance of my time, and
recognize the gentlelady from California.
Ms. Solis. Thank you, and good morning. Thank you, Mr.
Chairman, for also holding this very important meeting today.
I want to thank all the witnesses that will be speaking to
us this morning also. The need for safe water, as you know, is
universal. And I was shocked, also, when I first learned that
the DC lead problem came to our attention back in January
through The Washington Post story that broke at that time.
I was disturbed that it took a newspaper to bring our
attention to this very public problem, and I am appreciative
that the Government Reform Committee was able to take initial
action to hold investigative hearings, and that Chairman
Gillmor has brought the GAO and other witnesses in before us
today.
I think it is important that we learn not only what
happened in Washington, DC, and why, but that we continue these
dialogs in a bipartisan way to develop comprehensive policies
to address both water infrastructure and water contaminants. We
have known for many years that lead is toxic and can cause
developmental disabilities.
As other sources of lead exposure decline, keeping water
safe from lead remains an outstanding need. While we remove
lead from paint in homes, we continue to put children at risk
with the water they use in daycare centers and in schools.
My concern about lead led me to co-sponsor H.R. 4268, the
Lead-Free in DC Act. I believe the bill is a good start for
comprehensive action to combat lead, and I also believe that
the lead situation exposes major problems with our Nation's
water infrastructure.
In a recent poll by Republican pollster Frank Luntz, 91
percent of those polled believe if a city is willing to invest
billions annually in highways and airlines, it should be
willing also to invest in safe drinking water. Despite the
public support, our water systems are crumbling and decrepid,
and yet we fail to invest in our infrastructure.
We have approximately 900,000 miles of pipes of water
mains; 238,000 water mains break each year. Ten percent of
treated water is lost because of deteriorated pipes, and we
can't afford to continue losing 10 percent of treated water
because we don't invest in our infrastructure, yet the State
revolving loan fund is funded at $150 million below its
authorized level. That bothers me.
If the revolving loan fund was fully funded, California
could potentially receive an additional $15 million a year for
infrastructure projects. Fifteen million is a lot of money for
a State struggling right now with a budget that is broke.
Other contaminants are also problems in my district. In the
San Gabriel Valley, which is a part of my district, we have
major problems with perchlorate, a rocket fuel used largely by
the military, NASA, and governmental contractors. Instead of
working to help provide safe drinking water, the Department of
Defense was here just a few months ago asking for liability
relief.
We shouldn't have to fight the contractors of Department of
Defense for safe water. We should receive support from EPA to
get safe water. Our water providers can't plan if EPA doesn't
provide them support, and I am very proud of the work that has
gone on locally in the district that I represent.
Through a lot of hard work, the city of Baldwin Park now
has the Nation's first perchlorate treatment facility. But this
facility was not achieved without major expense, and
perchlorate is not the only new contaminant that we must deal
with.
The lack of infrastructure and contamination of our water
supply is a national problem. This solution must address
funding, infrastructure, and contaminant standards. And I look
forward to working with Chairman Gillmor and other members of
this committee to solve these problems.
Mr. Chairman, I would also like to request unanimous
consent to submit the opening statement from our ranking
member, Mr. Dingell.
[The prepared statement of Hon. John D. Dingell follows:]
Prepared Statement of Hon. John D. Dingell, a Representative in
Congress from the State of Michigan
It has been many months since we first learned from The Washington
Post that drinking water in the Nation's capital is contaminated with
lead and is frequently not fit to drink straight from the tap. Multiple
hearings have already been held in the House and Senate since the story
broke. This is the first opportunity, however, that we have had in this
Subcommittee to deal with this and other pressing drinking water
issues. This Subcommittee is charged with oversight of drinking water
matters in the House and so we have a special responsibility to ensure
that we exercise vigorous oversight to protect the public interest. I
welcome the chance to begin to get to the bottom of this and other
pressing drinking water concerns.
The origin of the drinking water crisis in Washington appears to
stem in part from problems in management and communications at the
local and federal level. But the drinking water crisis here in
Washington also highlights the apparent absence of adequate regulations
in this area. I, along with Rep. Solis, and several colleagues in the
U.S. Senate, have asked the GAO to evaluate the effectiveness of the
lead and copper rule and we are very interested in the results of that
effort.
I understand the Environmental Protection Agency (EPA) is also
currently reviewing the lead regulations and has held a few workshops
on the matter. I look forward to hearing more about what specific steps
are being taken and I would like to know what the time-line is for
action in this effort. Given what may be at stake, including the health
of our children and grandchildren, I suggest that an aggressive and
rapid response is in order.
A broader problem highlighted by the Washington drinking water
crisis is the neglected and decayed infrastructures of our public water
systems. These systems protect the public health and provide safe
drinking water for our citizens, yet are often aging and often in
disrepair. For example, in Detroit, pipes that were first installed in
1887--over 100 years ago--are still being used. The EPA reported in
2001 that the current needs to ensure provision of safe drinking water
to our people are $102.5 billion and growing--a huge sum of money.
Billions more will be needed for future years.
At the last subcommittee hearing on this issue in April 2002,
witnesses from the Association for State Drinking Water Administrators,
American Metropolitan Water Association, National League of Cities, and
the American Water Works Association all supported a $20 billion
increase over five years in the Drinking Water State Revolving Loan
Fund authorization. That would increase the $1 billion authorized by
the 1996 Drinking Water Amendments to $4 billion a year. Some thought
it should be even higher.
Against the well-documented financial needs for replacement and
rehabilitation of aging drinking water infrastructure, the President's
budget for FY 2005 was only $850 million for the State Revolving Loan
Fund--$150 million less than the $1 billion Congress authorized when
the Fund was created. I now understand that Administration budget
proposals maintain this flat-line funding of $850 million per year for
the Drinking Water Revolving Loan Fund until 2018. This level ignores
the needs of our cities and public water systems.
Yet another threat to our drinking water is EPA's failure to set
standards for contaminants such perchlorate which we now know are
widespread and pose a serious threat to public health. The Department
of Defense is refusing to clean up perchlorate contamination at more
than 50 facilities nationwide until the EPA sets a maximum contaminate
level (MCL) for perchlorate. I look forward to hearing what, if
anything, EPA is doing to address this problem.
Immediate action is necessary to address the threats to safe
drinking water that we are currently facing. But we continue to see
only slow progress and little financial commitment to one of the
nation's most important resources. Ignoring the problem, or postponing
needed fixes, will only put the public health at greater risk and make
eventual corrective action more costly.
Mr. Gillmor. Without objection, so ordered. And I am very
pleased that we have here the chairman of the full committee,
Mr. Barton.
Chairman Barton. Thank you, Mr. Chairman. I want to thank
you for holding this hearing about the lead in the District of
Columbia's drinking water and infrastructure. When the report
surfaced late last January about the discovery of elevated lead
levels in the drinking water of our Nation's capital, I was
very alarmed to find that something that we take for granted,
such as a glass of water from the tap, could be contributing to
increased exposure of lead.
I wondered how this could be going on for the past few
years. How could the public and the paying consumers of the DC
Water and Sewer Authority and the Congress have been kept in
the dark about this for so long?
As the committee with jurisdiction over the Safe Water
Drinking Act, I want to applaud you, Chairman Gillmor, for your
prompt response to this issue, for your request to review the
issues that face EPA and the DC Water and Sewer Authority. I am
very pleased that you have requested a separate GAO study to
help understand the root causes of the District's water
problems and how to prevent such occurrences in the future.
Perhaps after we get the results of this report we can
assess the internal assessments of EPA, WASA, and others, and
come up with a comprehensive solution to prevent the problem
from happening in the future. We have begun to shed some light
on what happened in the past.
It is my understanding that the Corps of Engineers has
adopted a new corrosion control treatment process, and it is
having some success. In June of this year, EPA determined,
unfortunately, that WASA violated Federal law by failing to
properly notify the public of unsafe levels of lead in their
water supply, and they also withheld key test results that
would have revealed the problem much earlier.
I understand that a consent agreement has been reached
between the EPA and WASA in which WASA has agreed to improve
its public education program, update its data base management
system, and replace some lead service lines. Also, I am told
that in June the Corps has begun to test a process that uses a
phosphate-based corrosion inhibitor that would address the lead
leaching in the pipes. I understand that work in this area has
appeared to be successful, at least in the initial stages.
The review of lead issues in DC also brings up other
critical issues about the Safe Water Drinking Act. I hope that
these issues will lead to a healthy discussion on how EPA and
utilities are sustaining current infrastructure, and the role
of the Federal Government, the States, and local water
utilities in providing safe drinking water for all of our
Nation's 54,000 community-based water systems.
I want to thank our four witnesses on this first panel for
appearing today, and the witnesses on the other panels that are
going to appear after them. I think that their testimony will
help us develop a comprehensive record from which we can take
whatever steps are necessary to improve and protect the water
supply here in the District of Columbia.
With that, Mr. Chairman, I yield back the balance of my
time.
[Additional statements submitted for the record follow:]
Prepared Statement of Hon. C.L. ``Butch'' Otter, a Representative in
Congress from the State of Idaho
Thank you, Mr. Chairman, for holding this hearing today.
Providing safe drinking water for our communities is and should be
a top priority. We all have heard of DC's water problem, and I am glad
this committee is holding this oversight hearing to look into the cause
of the high lead levels and what is being done to correct this problem.
We are fortunate in Idaho that, according to our State Department
of Environmental Quality, we do not have a problem with lead in the
drinking water. Since many of our water systems are newer than DC's, we
fortunately have not seen similar problems. However, Idaho does have a
significant problem with naturally occurring arsenic in our water
systems.
Idaho is similar to the District in that the EPA runs the clean
water program. The EPA--not Idaho--is responsible for implementing the
new arsenic standard of 10 parts per billion, down from 50 parts per
billion. We are having some problems in Idaho right now with the way
EPA is implementing this rule. In many cases we are dealing with small
rural communities with limited resources. Coming down on these
communities with the heavy hand of the federal government isn't the
best way to achieve our shared goal of clean water.
I want to thank Mr. Grumbles for coming into my office earlier this
week to discuss our problem. I look forward to continuing to work with
you in addressing the way the arsenic rule is being implemented in
Idaho. However, I remain concerned that the arsenic regulation will
have very adverse economic impacts on thousands of rural communities
across the nation, without addressing legitimate human health concerns.
Since there is no economically feasible way for many small communities
to meet this standard, and the new standard itself may result in no
health benefits, I support allowing each eligible rural community to
decide whether to comply. That's why I introduced HR 4717, the Small
Community Options for Regulatory Equity Act.
I also am hopeful that the committee will consider reviewing the
science that led to the lower arsenic standard. More scientific studies
are coming out that raise questions about the earlier analysis. When we
set regulations such as the arsenic standard, which have such a large
price tag, we must be sure they are backed up by sound science. I
understand that the EPA is working on a perchlorate standard. I am
hopeful that the EPA only moves forward with very sound science to back
up any decision that is made. Thank you, Mr. Chairman I look forward to
the testimony from the witnesses.
______
Prepared Statement of Hon. Janice D. Schakowsky, a Representative in
Congress from the State of Illinois
Thank you, Mr. Chairman, for holding this hearing today. I am happy
to see that our Subcommittee is looking into the drinking water problem
in the District of Columbia. The unconscionably high levels of lead
that D.C. residents have been exposed to have jeopardized the health
and well-being of thousands of men, women and children. It is crucially
important that we know how the situation in D.C. progressed to this
level and that we evaluate appropriate ways to fix this problem. This
should serve as a lesson for us to prevent similar problems elsewhere
in the nation.
Lead is highly toxic and a possible human carcinogen that is most
dangerous for small children. Lead builds up in their bodies and can
cause damage to kidneys, nerves and red blood cells. It may also be
responsible for causing adverse effects on development, growth,
reproduction, and metabolism by disrupting the endocrine system. The
District's water authorities attempted to downplay the hazards of lead
in drinking water because they wanted to ``avoid creating undue public
concern or alarm.'' In my view, no amount of concern is undue when
talking about such a major health threat to our children.
One of the major reasons that the large amount of lead in D.C.'s
water system was essentially ignored for years was a lack of
communication between agencies responsible for providing drinking water
to District residents. However, I urge my Colleagues and our witnesses
to look past the finger pointing and focus on the underlying problem.
The fact is that the Environmental Protection Agency's (EPA) rule to
protect water systems from lead contamination, the Lead and Copper Rule
(LCR), is weak and that our local water systems are not getting the
funding they need to provide our communities safe drinking water.
We must strengthen the LCR. Under the LCR, the Corps of Engineers
was allowed to use chloramines to disinfect the District's water
without adequately studying the chemical's impact on their efforts at
corrosion control. It is now apparent that the change aggravated the
lead problem. The LCR allowed the Washington Sewer and Water Authority
(WASA) to not do anything to help homes that tested more than ten times
over the action level until 10% of the samples exceeded the limit. The
District's water authorities used the fact that the LCR allows them to
dismiss some samples as ``invalid'' to avoid having to take action to
fix the problem sooner. Once the problem in D.C. became public, EPA
reviewed ``invalid'' samples from other water authorities and ruled
that several samples were in fact valid. As a result of EPA's review,
Boston, which was in compliance, was re-classified as above the action
level.
While we cannot entirely disregard the irresponsible actions of
those who knowingly put the public at risk, our role is to provide the
necessary resources to help support a safe drinking water system for
the District and the entire country. We have yet to follow through on
that duty. Replacing lead lines and other remedial actions are
expensive and our local water systems are already unable to meet the
needs of our overworked and aging water systems. We can help our local
water authorities update and improve our drinking water infrastructure
by funding the State Revolving Loan Fund. The EPA has testified that
the program needs at least $102.3 billion in additional funding for
local water utilities just to maintain compliance. President Bush's
FY05 request was just $850 million--$150 million less than the
authorized level and under the Draconian budget cuts and caps that we
have seen in the House this year, the funding picture will likely
become even bleaker. We cannot ignore this problem any longer.
Again, Mr. Chairman, thank you for holding this hearing today. I
look forward to hearing from today's witnesses and then beginning to
work to make sure that all of our constituents have safe drinking
water.
Mr. Gillmor. Thank you, Chairman Barton, and we will now
proceed to our first panel, and our first witness is Benjamin
Grumbles, who is the Acting Assistant Administrator for Water
in the U.S. EPA.
Mr. Grumbles?
STATEMENTS OF BENJAMIN H. GRUMBLES, ACTING ASSISTANT
ADMINISTRATOR FOR WATER, U.S. ENVIRONMENTAL PROTECTION AGENCY;
DONALD S. WELSH, ADMINISTRATOR FOR REGION III, U.S.
ENVIRONMENTAL PROTECTION AGENCY; THOMAS P. JACOBUS, GENERAL
MANAGER, WASHINGTON AQUEDUCT; AND JERRY N. JOHNSON, GENERAL
MANAGER, DISTRICT OF COLUMBIA WATER AND SEWER AUTHORITY
Mr. Grumbles. Thank you, Mr. Chairman, and ranking minority
member Congresswoman Solis, and also Chairman Barton. I
appreciate all of your interest and efforts in this, bringing
us together and calling for an investigation, and helping all
of us get to the bottom of this important situation. If there
is a silver lining to this whole situation of lead in drinking
water in the Nation's capital, it is this.
It is turning the Nation's attention to an incredibly
important issue of the health and safety of the Nation's
drinking water supplies, and also the importance of
infrastructure, water infrastructure and investing in that
valuable asset that determines the quality of life for all of
us in our communities.
What I would like to do is address some of the broader
national issues and what we are doing in response to the
situation. Don Welsh, who is accompanying me, the Regional
Administrator, EPA Region III, will also address some of the
more specific issues involving the District and the lead in
drinking water there.
Mr. Chairman, I would say a couple of things about how we
are responding to this situation. First and foremost, everyone
understands that lead is of grave concern from a public health
perspective, and EPA places a high priority on reducing
exposure to lead.
In the drinking water arena, we have a lead and copper rule
that was finalized in 1991. When this situation arose in the
District here, I think it brought a great degree of attention
to the issue and to the importance of reviewing whether this is
a national problem, seeing how effective the rule has been over
the last 13 years, and also seeing how it is implemented and
whether there should be revisions either to the rule or to the
guidance.
EPA is carrying out a national compliance review. This is a
full throttle review of the existing rule and also the guidance
that EPA has issued over the years. One of the very first
things that EPA did was to write to each of the States and to
get information from the States, because they are the ones,
with the exception of the District of Columbia and Wyoming,
they are the ones who are really the front line implementers of
the drinking water rule and programs with their communities.
We have the 90th percentile data that we have collected--
that is, the data under the lead and copper rule--to help us
answer that first question. Is this a pervasive national
problem? The results so far, Mr. Chairman, are that it is not a
pervasive national problem. It is an extremely important
problem in some areas of the country, some local communities,
but our data indicates that less than 4 percent of the large-
and medium-sized community water systems have experienced
exceedances of the 15 parts per billion standard. That doesn't
mean that we should stop working to reduce that even further,
but I think it is important to keep that in mind.
The other key issue is: how well has the rule worked since
1991? It is important to keep in mind that we are seeing
reduced numbers of exceedances--exceedances over the 15 parts
per billion number. We are also seeing that there is a
reduction in the number of kids who have blood lead levels that
exceed the 10 micrograms per deciliter standard that has been
established through CDC and EPA. We are seeing the reductions
there.
A lot of that is also attributed to the great work that
this committee has done, and that the Congress has done, that
the agency has done, to remove the threats of lead paint and
also lead in gasoline. But with lead in drinking water, I mean,
we have seen progress in terms of protecting children.
One of the other things that we are doing is that we are
conducting national workshops on key issues, such as the
difficult challenges that utilities face in complying with the
multitude of drinking water regulations, the simultaneous
compliance issue.
We held a workshop in May in St. Louis on the importance of
sampling protocols and monitoring protocols. That is such an
important part, and it is a lesson that all of us can learn on
the lead situation in the District. How are the monitoring and
sampling protocols being carried out? Can the public have
confidence in the numbers? And, most importantly, can the
public be aware, ahead of the curve, so that appropriate
precautions and steps can be taken?
A very high priority of the agency is to look very closely
at schools and daycare facilities. There are over 100,000
elementary schools in the country. There are approximately
500,000 daycare facilities. The important question is, how safe
is the drinking water in those schools and facilities?
One of the EPA's priorities, and certainly one of my top
priorities, is to get all of the information we can from the
States and the communities and to see how much testing, how
much monitoring is going on, and what is the quality of the
drinking water in the schools.
And I think we need to do more work on that front, and I
think it needs to be a bipartisan partnership among the
agencies, the Congress, and the States, and the utilities--
those that provide the drinking water to the customers,
including the schools and the daycare facilities.
We are committed to holding additional workshops throughout
the year. We have--we are scheduling an additional workshop
with experts on some of the important issues of lead service
line replacement and schools, what more can be done for schools
and daycare facilities, and, importantly, public education and
risk communication.
I would conclude on the lead front by saying that one of
the key lessons that we have learned from this, and are
continuing to learn, is the high importance of effective,
early, accurate reporting, useful information to the public.
The last thing, Mr. Chairman, I would like to comment on in
my time is the importance of infrastructure. This committee was
instrumental in moving through bipartisan landmark legislation
in 1996 to set up the Safe Drinking Water Act revolving loan
funds. We are fully supportive of that model and are pleased
that the President's budget includes $850 million.
The Congress has been providing this amount. That is
certainly one tool--one tool. It certainly won't meet all of
the needs, but it is a helpful tool to deal with the
infrastructure needs and investments.
The last thing I would mention, one of the priorities of my
office and of the administration, is to promote sustainable
infrastructure. The President's budget request includes a
sustainable infrastructure initiative, and what that really
means is, given that the State--the Federal/state revolving
fund is not, and cannot be, the sole tool in the tool box to
address investments in infrastructure needs, we need to promote
sustainability.
We need to advance asset management and develop the
technical, financial, and managerial capacity of the Nation's
drinking water systems. We need to promote water conservation,
water use efficiency. One of the priorities of my office is
advancing a water star program modeled on energy star,
voluntary water efficiency labeling programs, so that consumers
will be able to choose smartly to save money, save water, save
the environment, by selecting appliances or water products that
use less water. We are very excited about that and look forward
to working with cities and Congress and others to advance water
conservation.
Other components of sustainability include full cost
pricing. We recognize that there are situations where there
need to be lifeline rates, and it is an inherently local
decision as to what the price ought to be. But we want to
encourage conservation pricing and various mechanisms to help
with the overall investment of our Nation's infrastructure.
And the last is taking a watershed-based approach, looking
at source water protection as a real opportunity to reduce
problems down the road, treatment costs, and overall pollution
prevention.
So, Mr. Chairman, I appreciate the members convening this,
and your leadership on this effort, and look forward to
answering any questions that you or your colleagues have.
[The prepared statement of Benjamin H. Grumbles follows:]
Prepared Statement of Benjamin H. Grumbles, Acting Assistant
Administrator for Water, U.S. Environmental Protection Agency
Good morning, Mr. Chairman and Members of the Committee. I am
Benjamin Grumbles, Acting Assistant Administrator for Water at the
United States Environmental Protection Agency (EPA). I welcome this
opportunity to speak to the Committee about the issue of lead in
drinking water, the actions that EPA has been taking at the national
level to address the matter, and the broader issue of water
infrastructure. Regional Administrator Welsh will provide you with
information on the activities underway to address the specific
situation related to elevated lead levels in the District of Columbia's
(D.C.'s) drinking water.
LEAD AS A PUBLIC HEALTH CONCERN
EPA places a high priority on reducing exposure to lead. This
contaminant has been found to have serious health effects, particularly
for children. Health effects may include delays in normal physical and
mental development in infants and young children; slight deficits in
the attention span, hearing, and learning abilities of children; and,
high blood pressure in some adults (which may lead to kidney disease
and increased chance of stroke). But pregnant women and children are
our primary concern. The Centers for Disease Control and Prevention
(CDC) has identified a blood lead level of 10 micrograms per deciliter
as the level of concern for lead in children. Nationally, approximately
2% of children between the ages of 1 to 5 were estimated to have blood
levels that exceeded the level of concern for the period 1999-2000, a
significant decrease from the 88% estimated to exceed that level for
the period between 1976 to 1980. [Surveillance for Elevated Blood Lead
Levels Among Children--United States, 1997-2001. Centers for Disease
Control and Prevention. Surveillance Summaries, September 12, 2003.
MMWR 2003:52 (No. SS-10)].
The most common source of lead exposure for children today is lead
in paint, dust, and soil in older housing [see Risk Analysis to Support
Standards for Lead in Paint, Dust and Soil (EPA 747-R-97-006, June
1998] This is primarily from housing built in the 1950s and homes with
pre-1978 paint. Several Federal programs and surveillance and
prevention programs at the State and local level continue to work
towards reducing exposure to lead. In addition, EPA works with Federal
agencies through the President's Task Force on Environmental Health
Risks and Safety Risks to Children--on implementing a federal strategy
to prevent childhood lead poisoning.
LEAD IN DRINKING WATER
Although, in most circumstances, the greatest risks are related to
paint, dust and soil, lead in drinking water can also pose a risk to
human health. To reduce potential exposure to lead, EPA has set a
maximum contaminant level goal of zero for lead in drinking water and
has taken many actions over the last 20 years to reduce lead in
drinking water. The 1986 Amendments to the Safe Drinking Water Act
(SDWA) banned the new use of lead solder, and leaded pipes from public
water supply systems and plumbing, and limited faucets and other brass
plumbing components to no more than 8% lead. To address lead in
schools, the Lead Contamination Control Act (LCCA) of 1988 recalled
drinking water coolers with lead-lined water reservoir tanks, and
banned new drinking water coolers with lead parts. The 1986 SDWA
Amendments also directed EPA to revise its regulations for lead and
copper in drinking water.
An interim standard for lead in drinking water of 50 micrograms per
liter, or parts per billion (ppb), had been established in 1975.
Sampling of customer taps was not required to demonstrate compliance
with this standard. In 1988, the Agency proposed revisions to the
standard and issued a final standard in 1991. The revised standard
significantly changed the regulatory framework. Unlike most
contaminants, lead is not generally introduced to drinking water
supplies from the source water. The primary sources of lead in drinking
water are from lead pipe, lead-based solder used to connect pipe in
plumbing systems, and brass plumbing fixtures that contain lead.
Setting a standard for water leaving the treatment plant fails to
capture the extent of lead leaching in the distribution system and
household plumbing.
EPA requires public water suppliers to meet the regulations
governing treated water quality distributed via the public water
system. The regulations do not require homeowners to replace their
plumbing systems if they contain lead. To reduce consumers' lead
exposure from tap water, EPA used its available authorities to require
public water suppliers to treat their water to make it as non-corrosive
as possible to metals in their customers' plumbing systems. These
treatment requirements were issued in EPA's Lead and Copper Rule (LCR)
on June 7, 1991.
The rule requires systems to optimize corrosion control to prevent
lead and copper from leaching into drinking water. Large systems
serving more than 50,000 people were required to conduct studies of
corrosion control and to install the State-approved optimal corrosion
control treatment by January 1, 1997. Small and medium sized systems
are required to optimize corrosion control when monitoring at the
consumer taps shows action is necessary.
To assure corrosion control treatment technique requirements are
effective in protecting public health, the rule also established an
Action Level (AL) of 15 ppb for lead in drinking water. Systems are
required to monitor a specific number of customer taps, according to
the size of the system, with a focus on sites that have lead service
lines or lead-based solder in their plumbing systems. If lead
concentrations exceed 15 ppb in more than 10% of the taps sampled, the
system must undertake a number of additional actions to control
corrosion and to inform the public about steps they should take to
protect their health. If a water system, after installing and
optimizing corrosion control treatment, continues to fail to meet the
lead action level, it must begin replacing the lead service lines under
its ownership. The rule was subsequently revised in 2000 to modify
monitoring, reporting and public education requirements, but the basic
framework, including the action level, was not changed.
ACTIONS UNDERTAKEN BY EPA HEADQUARTERS TO ADDRESS THE D.C. SITUATION
As Regional Administrator Welsh will describe, EPA has been working
with WASA and the Washington Aqueduct, managed by the U.S. Army Corps
of Engineers, which supplies water to WASA, to identify a treatment
solution to reduce levels of lead from customer taps in many
Washington, D.C. homes.
I fully understand the concerns that Congressional Members and
Committees and City Leaders have regarding timely and effective public
notification. EPA is reviewing the actions taken by all parties to
ensure that we use the lessons learned to prevent such an event from
taking place in the future--here in D.C. and in other communities
across the nation. While the situation in D.C. appears to be unique, we
are continuing to investigate the matter. However, in surveying States
and regions, we have not identified a systemic problem of increasing
lead concentrations in tap monitoring conducted by public water
systems.
Staff from my program and EPA's Office of Research and Development
have been working closely with the Region to provide technical
assistance and are participating on the Technical Expert Working Group
(TEWG) evaluating potential technical solutions to elevated lead
levels. My staff convened a peer review panel to carry out an
independent review of the TEWG's Action Plan. The input of the peer
reviewers facilitated an acceleration of the technical solution to the
problem that Regional Administrator Welsh will discuss.
NATIONAL ACTIONS TO EVALUATE LEAD IN DRINKING WATER
As head of the national water program, I have directed my staff to
undertake several major actions to address the specific issue of lead
in drinking water from a national perspective.
National Review of Compliance and Implementation of the Lead & Copper
Rule
My staff are working with our enforcement and regional drinking
water program managers to embark on a thorough review of compliance
with, and implementation of, the LCR. Our review will answer three
questions:
1. Is there a national problem? Do a significant percentage of systems
fail to meet the lead action level? Does a significant
percentage of the population receive water that exceeds the
lead action level?
2. How well has the rule worked to reduce lead levels in systems over
the past 13 years, particularly in systems that demonstrated
high lead levels in the initial rounds of sampling?
3. Is the rule being effectively implemented today, particularly with
respect to monitoring and public education requirements?
Our initial focus is to ensure that EPA has complete and accurate
information on the LCR in its Safe Drinking Water Information System
(SDWIS). States were required to report specific results of monitoring
(i.e., 90th percentile lead levels) to EPA for systems serving
populations greater than 3,300 people beginning in 2002. In March, I
asked EPA Regional Administrators to work with the States to ensure
that all available information was loaded into the data system. As of
June 1, 2004, states had submitted information to SDWIS for 89% of the
8,667 active systems in the country that serve more than 3,300 people.
The most recent summary of the data received was made available to the
public on June 23. For large systems (serving more than 50,000 people),
the summary indicates that 12 systems, one of which is D.C., exceeded
the action level during a monitoring period that ended in 2003. Those
12 systems serve a total of 5.2 million people, although the population
actually exposed to elevated lead levels in each community is likely
lower. This is due to the nature of lead occurrence, which is largely
due to leaching of lead from lead service lines and plumbing fittings
and fixtures, and thus site-specific to homes that have those fixtures.
An analysis of data for medium systems (those serving between 3,330 and
50,000) showed that 76 systems serving a total population of 1 million
also exceeded the action level during 2003. Overall, we found that only
3.4% of the systems (27 of 744 large and 237 of 6,958 medium systems)
for which we have data exceeded the lead action level during one or
more monitoring periods since 2000.
Although we are currently seeing problems in the District, it
appears that the 1991 regulation, which required systems serving more
than 50,000 to install corrosion control, has been effective in
reducing lead concentrations, and thus, the public's exposure to lead
in drinking water. However, even though we have had success in reducing
exposure, we must remain vigilant to ensure that treatment continues to
control corrosion and that information on potential risks is
communicated to the public. EPA continues to collect data and will
release additional reports later this summer.
We are reviewing the systems that exceeded the action level in the
initial rounds of sampling. We will work with our regional staff and
states to better understand the actions taken by systems to address
elevated levels of lead and whether those actions have been effective
in lowering lead levels. Later this year we will embark upon a review
of state programs to determine if the rule is being effectively
implemented by those systems that have recently exceeded the action
level.
Expert Workshops
Another important part of EPA's national effort is to review
existing requirements of the rule and associated guidance to determine
if changes should be made to help utilities and states better implement
the rule. The provision of safe drinking water is not an easy task.
Treatment processes must be balanced to address multiple risks. EPA has
developed guidance to assist systems in selecting among corrosion
control treatment options and in balancing treatment processes when
working to achieve simultaneous compliance with different standards.
EPA has also released guidance to help utilities carry out effective
public education and monitoring programs.
To help obtain additional information from experts, EPA is holding
workshops on several components of the LCR Rule. The first two
workshops were held in St. Louis, Missouri in mid-May. Thirty experts
in corrosion control, water treatment, sampling and laboratory analysis
participated in one or both of the workshops, and more than twenty
observers attended. The first addressed utility experiences in managing
simultaneous compliance with multiple drinking water rules and the
second addressed sampling protocols for the rule. The experts noted
that additional Agency guidance is needed to aid water systems in
evaluating treatment changes, including disinfection changes and
changes to coagulation processes, and the effectiveness of different
corrosion inhibitors. The experts also identified concerns with
distribution system maintenance and impacts of household plumbing on a
system's ability to comply with the rule. Participants suggested that
EPA review sampling provisions including the tiering criteria that
identify households for sampling and also suggested additional guidance
on what monitoring is appropriate to evaluate the effects of treatment
changes.
Experts in both workshops also identified issues that they and EPA
believe warrant expert discussion in future workshops. These issues
include small system issues, health effects of lead and risk
communication, lead service line replacement requirements, monitoring
for lead in schools, and removal of lead from brass alloys used in
plumbing fixtures and other devices. EPA will hold a workshop on public
education in September and will schedule meetings on additional
subjects such as lead service line replacement and lead in schools
later in the year.
Monitoring for Lead in School Drinking Water
One of my highest priorities is to use all available tools to
ensure that America's school children are not exposed to elevated lead
levels in their drinking water. While States and schools took action in
the late 1980's and early 1990's to remove harmful lead-lined coolers
in accordance with the 1988 Lead Contamination Control Act (LCCA), lead
solder and plumbing fixtures can still contain low levels of lead.
States and schools should continue to monitor their water outlets to
ensure that children are protected using EPA's recommended protocol for
testing water in schools for lead. In March, I sent letters to State
Directors of Health and Environmental Agencies seeking their help in
better understanding State and local efforts to monitor for lead in
school drinking water.
We heard from 49 states, Puerto Rico and the Navajo Nation and
provided a summary of the responses to the public this week. Generally,
states responded that they implemented the requirements associated with
the LCCA and continue to focus on ensuring that schools with their own
water system are in compliance with the LCR. A few have expanded
existing regulatory authorities to better address schools and day care
facilities and several states have developed specific programs focused
on improving drinking water quality and environmental health at
schools. Most states agreed that minimizing lead in drinking water
consumed by children is important and many are conducting surveys,
expanding outreach efforts and taking advantage of partnerships to help
them reach schools. However, states also indicated that it would be
difficult to expand programs beyond existing efforts because state
drinking water programs are challenged by shortfalls in funding. We are
using the responses from states to help us determine if updated or
additional guidance should be developed to help states and local
governments conduct more comprehensive monitoring in schools and day
care facilities.
DRINKING WATER INFRASTRUCTURE
This event has served as a reminder of what Americans generally
take for granted--that we can turn on our faucets, whenever we want, to
draw a glass of clean, safe water. It also reinforces the importance of
discussions Congress, EPA, states, water utilities and other
stakeholders are having about the nation's water infrastructure
challenges. The nation faces risks of interruption in service quality
and public health protection as a result of deterioration of aging
infrastructure or outdated components, such as the lead service lines
serving older homes in the District. In 2001, EPA released its second
drinking water infrastructure needs survey which identified that more
than $150 billion would be needed over the next 20 years to address
infrastructure needed to provide service and protect public health, $83
billion of which was associated with the pipes that carry water to and
from treatment plants to consumers.
In 2002, EPA released its Clean Water and Drinking Water
Infrastructure Gap Analysis, which used information from the Needs
Survey and other sources. The report estimated that the 20-year
drinking water infrastructure capital payment need is between $178
billion to $375 billion. The report also described the potential gap
that could develop if current levels of spending do not increase to
keep pace with needs that are increasing in response to aging
infrastructure and growing and shifting populations. EPA estimated
that, in the absence of additional spending, the total gap could range
from $0 to $267 billion, with a point estimate of $102 billion.
However, the report also estimated how the gap would change if
utilities took action to increase their revenue. If revenue were to
increase at a rate of 3% annually, over the rate of inflation, the gap
could shrink to between $0 to $205 billion, with a point estimate of
$45 billion.
While EPA's efforts were aimed at quantifying the gap at the
national level, the ultimate impacts of funding gaps are felt at the
local level. Local communities and utilities must make decisions on a
daily basis to determine how to balance needs and available funding.
For example, even if corrosion control treatment is effectively
controlling lead concentrations in drinking water, many water utilities
may have an ultimate goal of removing lead service lines from their
service areas. However, utilities must consider that goal within the
context of funding other public health priorities--to replace aging
distribution pipes, the failure of which could result in microbial
contamination, or to install treatment to comply with new and/or more
stringent drinking water standards. Meeting current and future
infrastructure needs will require significant levels of commitment on
the part of local, state and federal governments and an understanding
of the true investment needs on the part of customers.
This Administration has made a commitment to continue funding our
principal drinking water capital financing program, the Drinking Water
State Revolving Fund program, at $850 million annually through 2018 to
help capitalize state programs that have already provided more than $6
billion to finance projects within their states. However, it is clear
that federal funding will not be able to meet all of the needs. Local
communities and utilities need to ensure that their operations are
sustainable for the long-term.
EPA's Sustainable Infrastructure Initiative, for which we have
requested funding in the FY 2005 appropriation, is aimed at helping to
encourage and promote actions that provide for better utility
management, full-cost pricing of services and efficient use of water.
Water conservation saves money for families, reduces infrastructure
costs and protects the environment, which is why EPA and others are so
enthusiastic about identifying and promoting incentives such as the
potential new ``Water Star'' program, modeled, in part, on the
successful Energy Star program. The Sustainable Infrastructure
Initiative also promotes infrastructure decisions within the context of
the watershed. For example, utilities and communities need to determine
how source water protection will help them to avoid expenditures
related to increasing treatment. EPA looks forward to working with all
interested parties to implement the initiative and determine how we can
meet the challenges that face the nation's water infrastructure.
CONCLUSION
Mr. Chairman, this reminds us all of the importance of
communication--especially with the public. To maintain public health
and confidence, information communicated to the public must not only be
accurate, but timely, relevant and understandable. While I believe that
communication efforts on the part of the Region, the District's
Department of Health and WASA have improved, there is still much to be
done to ensure that the city's residents are aware of the steps they
can take to protect their health.
The review of compliance and implementation, expert workshops and
other efforts underway will help the Agency to determine whether it is
appropriate to develop additional training or guidance or make changes
as part of our review of existing regulations. Our immediate goal is to
ensure that the residents and D.C. receive safe water and, more
generally, that systems and States have the information they need today
to fully and effectively implement the rule and minimize risks to
public health.
We will continue to work closely with Congress, our public service
partners and concerned citizens to investigate the situation in D.C.
and to review implementation of the rule nationwide. EPA wants to
ensure that citizens across the country are confident in the safety of
their drinking water.
Thank you for the opportunity to testify this morning. I am pleased
to answer any questions you may have.
Mr. Gillmor. Thank you, Mr. Grumbles.
And we will go to Don Welsh, who is the Region III
Administrator for EPA.
Mr. Welsh?
STATEMENT OF DONALD S. WELSH
Mr. Welsh. Good morning, Mr. Chairman, and members of the
subcommittee. I am Don Welsh, Regional Administrator for Region
III of the U.S. Environmental Protection Agency.
Thank you for the opportunity to discuss the important
issue of lead in DC drinking water and to outline the steps EPA
and other agencies are taking to resolve the problem. There is
no higher priority for my office than to continue to work with
the city and other partners to protect those who live and work
in the District, and to correct the cause of elevated lead in
the water.
To that end, steps are underway to reduce lead levels in
tap water through corrosion control. Orthophosphate, a chemical
designed to inhibit corrosion in water lines, was applied to a
portion of the DC water system on June 1. If all continues to
go well, the treatment change is projected to be expanded to
the entire water system on or about August 9.
Lead levels in the partial system application area in the
northwest section of the District remain elevated. Corrosion
control experts have advised that actual reductions in lead
concentrations may not be seen for 6 months or longer. The
corrosion inhibitor must have time to buildup a protective
layer on the pipes in order to be fully effective.
Meanwhile, the public needs to continue to follow the
consumer guidance for tap water flushing and the health
guidance on the use of water filters, where supplied. By way of
background, the EPA's lead and copper rule requires water
systems to optimize corrosion control to prevent lead and
copper from leaching into drinking water.
To assure corrosion control is effective, the rule
establishes an action level of 15 parts per billion for lead.
If lead concentrations exceed 15 parts per billion in more than
10 percent of the taps sampled, the system must intensify
sampling and take a number of additional actions to control
corrosion and to educate the public about steps they should
take to protect their health. The system must also begin a lead
service line replacement program.
Such was the case in the District of Columbia where, over
the last couple of years, lead concentrations in tap water in
many homes increased well above the 15 parts per billion action
level. While WASA took certain actions then to address the
requirements in the lead and copper rule, a recent compliance
audit and a review of outreach efforts have identified many
areas where the Authority's efforts fell short of meeting the
spirit and, in a number of instances, the letter of the rule.
We have come a long way over this year in meeting the
challenges posed by lead in DC drinking water. WASA and the
city have undertaken a series of activities directed by EPA to
address the immediate public health threat, including the
delivery of more than 32,000 water filters and consumer
instructions to customers with lead service lines and others.
In addition to these ongoing actions, EPA last month
entered into an administrative order on consent with WASA that
will result in further public health safeguards. The provisions
of the consent order are intended to reinforce the important
safeguards provided for under the Federal Safe Drinking Water
Act.
The order was a result of an extensive 4-month audit of
WASA's compliance with the lead and copper rule. The audit
included onsite review of records and detailed evaluation of
thousands of pages of documents. EPA found that WASA failed to
comply with a number of lead sampling, public notification, and
reporting requirements.
Under the consent order, WASA must accelerate lead service
line replacement, enhance public education and outreach, and
improve its monitoring, data management, and customer response
practices, all beyond the baseline of regulatory requirements.
The most recent lead and copper compliance testing results
for the first 6 months of this calendar year were received on
July 7 and indicated that, once again, the 90th percentile
action level for lead was exceeded with a value of 59 parts per
billion.
In a separate initiative earlier this year, an EPA team
reviewed WASA's prior education and outreach efforts and
identified a number of steps WASA can take to achieve more
effective public education and outreach regarding lead in
drinking water. In addition to following mandatory
requirements, and making use of extensive EPA guidance, the
report recommends that WASA use consultants to help effectively
inform the public.
The report also included recommendations for EPA Region III
to improve our oversight of WASA's public education program,
and we have revised our standard operating procedures
accordingly. Other changes in procedure will ensure that a team
of EPA staff members with a variety of programmatic,
regulatory, and enforcement expertise sees each compliance
report filed by WASA and the Washington Aqueduct.
In addition to our collaborative efforts with the city, EPA
has taken a number of actions to provide information directly
to residents and others on the issue of lead in the District's
drinking water, including the establishment of a special lead
education program called Lead-Safe DC.
Finally, EPA has also received results that show the lead
action level was exceeded during the most recent sampling
period with 90th percentile results of 19 and 25 parts per
billion at two locations operated by the Naval District
Washington, the Navy Yard, and the Nebraska Avenue Complex.
Naval District Washington, which obtains its water from
WASA, has taken action to install and maintain water filters,
notify residents, provide guidance on tap flushing procedures,
resample locations, take fixtures out of service, and
investigate potential sources of lead. Working closely with the
District of Columbia, our public service partners, and
concerned citizens, we will continue to aggressively act to
protect residents and resolve the lead problem.
We are taking action to hasten the day when the citizens of
the District of Columbia can once again be confident in the
safety of their drinking water.
Thank you for the opportunity to present this information
this morning, and I am pleased to answer any questions that you
have.
[The prepared statement of Donald S. Welsh follows:]
Prepared Statement of Donald S. Welsh, Administrator, Region III, U.S.
Environmental Protection Agency
Good morning, Mr. Chairman and Members of the Subcommittee. I am
Donald Welsh, Regional Administrator for Region III of the U.S.
Environmental Protection Agency. Thank you for the opportunity to
discuss the important issue of lead in D.C. drinking water and to
outline the steps EPA and other agencies are taking to resolve the
problem.
There is no higher priority for my office than to continue to work
with the city and other partners to protect those who live and work in
the District and to correct the cause of elevated lead in the water.
To that end, steps are underway to reduce lead levels in tap water
through corrosion control. Orthophosphate, a chemical designed to
inhibit corrosion in water lines, was applied to a portion of the D.C.
water system on June 1. EPA authorized the action on the advice of a
Technical Expert Working Group with concurrence by an Independent Peer
Review Panel of corrosion control specialists. Both the working group
and the review panel were established by EPA to inform key decisions in
the process.
The treatment change has proceeded without incident. There have
been no known customer complaints of discolored water, and water
testing reported to us by the D.C. Water and Sewer Authority (WASA) and
the Washington Aqueduct show no unexpected results. If all continues to
go well, the treatment change could be expanded to the entire water
system within weeks.
Lead levels in the partial system application area in a northwest
section of the District remain elevated. Corrosion control experts have
advised that actual reductions in lead concentrations may not be seen
for six months or longer. The corrosion inhibitor must have time to
build up a protective layer on the pipes in order to be fully
effective.
Meanwhile, the public needs to continue to follow the consumer
guidance for tap water flushing and the health guidance on the use of
water filters where supplied. Local agencies and EPA will notify the
public when these measures are no longer needed.
The Washington Aqueduct and WASA will maintain the modified
treatment within set water quality parameters and monitor the system
closely throughout the partial system application. The additional
equipment installed by the Aqueduct to help maintain the required pH
levels in this area continues to perform well.
If no unresolvable issues are found during the partial system
application of treatment, the approved plan calls for full system
application of orthophosphate as soon as feasible. Last month, the
Washington Aqueduct reported that the current projection is for the
start of the full application on or about August 9.
PROTECTING PUBLIC HEALTH
By way of background, EPA's Lead and Copper Rule requires water
systems to optimize corrosion control to prevent lead and copper from
leaching into drinking water. To assure corrosion control is effective,
the rule establishes an action level of 15 parts per billion (ppb) for
lead. If lead concentrations exceed 15 ppb in more than 10 percent of
the taps sampled, the system must intensify sampling and take a number
of additional actions to control corrosion and to educate the public
about steps they should take to protect their health. The system must
also begin a lead service line replacement program.
Such was the case in the District of Columbia, where, over the last
couple of years, lead concentrations in tap water in many homes
increased well above the 15 ppb action level.
While WASA took certain actions then to address the requirements in
the Lead and Copper Rule, a recent compliance audit and a review of
outreach efforts have identified many areas where the authority's
efforts fell short of meeting the spirit and, in a number of instances,
the letter of the rule.
We have come a long way this year in meeting the challenges posed
by lead in D.C. drinking water. Prior to the completion of the
compliance audit and the signing of a resulting consent order, WASA and
the city had undertaken a series of activities directed by EPA to
address the immediate public health threat.
Those activities included:
The delivery of more than 32,000 certified water filters and consumer
instructions to occupants in homes with lead service lines and
others. Water filters continue to be sent out automatically,
along with a referral to the Department of Health, when tap
water test results indicate elevated lead levels.
Additional tap water sampling in buildings not served by lead service
lines, including schools, day care centers, businesses and
other facilities.
A commitment to accelerate the schedule for physically replacing lead
service lines in the District.
A modification of construction methods for service line replacement
to ensure they do not pose an undue risk to health in the days
or weeks following the replacement, while ensuring compliance
with the lead and copper regulation.
Expedited notification to customers of the results of water sampling
at their residences, committing to providing results in 30 days
or less.
In addition to these and other ongoing actions compelled in large
part by EPA and the city to provide protections and notifications for
lead in drinking water, EPA last month entered into an Administrative
Order on Consent with WASA that will result in further public health
safeguards.
CONSENT ORDER
The provisions of the consent order are intended to reinforce the
important safeguards provided for under the federal Safe Drinking Water
Act. The order was the result of an extensive, four-month audit of
WASA's compliance with the Lead and Copper Rule as far back as 1998.
The audit included on-site review of records and detailed evaluation of
thousands of pages of documents that were formally required by EPA.
During the audit, EPA found that WASA failed to comply with a number of
lead sampling, public notification and reporting requirements.
The most serious violation cited in the consent order was WASA's
failure to report all of the results of its tap water monitoring during
the period of July 2000 to June 2001. The regulations require that all
tap water monitoring samples be reported, unless a sample is
invalidated in accordance with EPA regulations. In this case WASA did
not obtain the required authorization to omit samples. If the samples
had been included, WASA would have exceeded the lead action level and
protective provisions would have been triggered a year earlier,
including efforts to understand and correct ineffective corrosion
control.
Under the consent order, WASA must accelerate lead service line
replacement, enhance public education and outreach, and improve its
monitoring, data management and customer response practices--all beyond
the baseline of regulatory requirements.
We are in the process of monitoring compliance with the order. To
date, we have received all required work products on schedule.
The most recent lead and copper compliance testing results--for the
first six months of this calendar year--were received on July 7 and
indicated that once again the 90th percentile action level for lead was
exceeded with a value of 59 parts per billion lead.
IMPROVED OUTREACH
In a separate initiative earlier this year, an EPA team reviewed
WASA's prior education and outreach efforts and identified a number of
steps WASA can take to achieve more effective public education and
outreach regarding lead in drinking water. In addition to following
mandatory requirements and making use of extensive EPA guidance, the
report recommends that WASA use consultants to help effectively inform
the public.
The recommendations were designed as key input to WASA's continuing
efforts to plan and carry out enhancements to drinking water education
efforts both for regulatory compliance and ``beyond compliance''
efforts.
The report also included recommendations for EPA Region III to
improve its oversight of WASA's public education program.
We have revised our standard operating procedures, in part, to
assure that shortcomings in public outreach are identified earlier and
corrected. Other changes in procedure will ensure that a team of EPA
staff members with a variety of programmatic, regulatory and
enforcement expertise sees each compliance report filed by WASA and the
Washington Aqueduct.
We will continue to look for additional ways to strengthen our
oversight procedures. There have been lessons learned in this process
that will benefit the agency in the future.
In addition to our collaborative efforts with the city, EPA has
taken a number of actions to provide information directly to residents
and others on the issue of lead in the District's drinking water,
including the establishment of a special lead education program, Lead
Safe D.C.
NAVAL DISTRICT WASHINGTON
Finally, EPA has also received results that show the lead action
level was exceeded during the most recent sampling period with 90th
percentile results of 19 and 25 ppb at two locations operated by the
Naval District Washington--the Navy Yard and the Nebraska Avenue
Complex. Naval District Washington, which obtains its water from WASA,
has taken action to install and maintain water filters, notify
residences, provide guidance on tap flushing procedures, resample
locations, take fixtures out of service and investigate potential
sources of lead.
CONCLUSION
Working closely with the District of Columbia, our public service
partners and concerned citizens, we will continue to aggressively act
to protect residents and resolve the lead problem. We are taking action
to hasten the day when the citizens of the District of Columbia can
once again be confident in the safety of their drinking water.
Thank you for the opportunity to present this information this
morning. I am pleased to answer any questions you may have.
Mr. Gillmor. Thank you very much, and we will go to Thomas
Jacobus. I hope I pronounced that correctly.
Mr. Jacobus. Yes, sir. That is correct.
Mr. Gillmor. Who is the General Manager of the Washington
Aqueduct.
STATEMENT OF THOMAS P. JACOBUS
Mr. Jacobus. Thank you very much, Mr. Chairman. I am Tom
Jacobus, General Manager of the Washington Aqueduct. I would
like to just take a few moments to summarize a little bit about
who we are, what our relationship is, both with EPA as the
regulator of our operations and our customer in the District of
Columbia, DC Water and Sewer Authority.
We are owned and operated by the Army Corps of Engineers,
which is a historic mission dating back to the inception of the
water supply. But we are regulated as a public water utility by
EPA Region III. We operate through the sale of water to our
customers, and those customers on a wholesale basis are the
District of Columbia Water and Sewer Authority, Arlington
County, Virginia, and the city of Falls Church, Virginia.
Falls Church further sells water and owns and operates the
distribution system in the immediate area of Fairfax County, of
surrounding Falls Church, out to the town of Vienna, and Vienna
is also a customer.
So there are about a million customers in our distribution
system, who have distribution systems which they operate,
buying the wholesale water from us. So all of the activities of
the Washington Aqueduct are paid for by the sale of water to
those customers, and all of our activities are regulated by EPA
Region III.
As a wholesale water--as a water provider, our interest is
the same as every other water provider in the United States,
and that is to provide safe, high-quality drinking water that
is reliably provided. There are many laws and regulations that
are imposed, quite rightly, on us, and we have gone to a great
deal of effort on behalf of our customers to build facilities
and provide the service that will meet those regulations.
At the same time, we are trying to provide water that is
100 percent reliable in the system. We are also making sure it
is bacteriologically pure, it is properly free of other
contaminants. We are looking at both chronic and acute effects
of the water.
We know that water is corrosive, and we have always had
some form of corrosion control in the water. In applying our
operation to the lead and copper rule that was promulgated in
1991, as you know, we, through a series of experiments, in-line
water treatment devices at the treatment plants, we determined
that using pH control--in other words, using lime to change the
scale of water from basic to acid--actually, the other way, we
want to make it more basic--that we would achieve sufficient
corrosion control. And those tests were validated with samples
taken at the tap.
So, in 1994, we began what we would--had determined and had
recommended to EPA as optimal corrosion control treatment at
the treatment plant serving all of those customers. After a
series of reviews and analysis, EPA finally gave us a letter of
authorization, and we have very, very carefully followed the
chemistry of the water to make sure that we have met the
optimal corrosion control.
If I could just jump back in time, in 2000, in November of
2000, we did change the treatment of the water in order to
comply with another regulation having to do with disinfection
byproducts. So when we change the way we disinfect the water
using a new chemical called chloramine, we had spectacular
results in lowering the disinfection byproducts, which was the
intent of the disinfection byproducts rule under the Safe
Drinking Water Act.
Then, we find in recent history, in 2000, 2003, results
reported by WASA that some elevated lead levels were showing
up. Our corrosion control was working exactly as planned, but
in the winter, January/February of this year, it became
apparent that the corrosion control technique that was being
carefully used and in place was not having a sufficient
protective effect.
So we immediately formed a group, a technical working group
to address the problem comprised of our customers, WASA
specifically, and then EPA and technical experts from outside.
We have, as members of the committee this morning have made in
their statements, started in a portion of our District of
Columbia service area with a phosphate inhibitor. Its
application is proceeding satisfactorily from a technical point
of view. In other words, we are getting the right amount of
phosphate to the tap. We are not having any secondary effects.
But as Mr. Grumbles, I believe it was, pointed out, it will
take many months to actually lay down a layer on the inside of
the pipe. We expect by mid-August to have that application full
system-wide, and our internal and external experts are
confident that we will be able, through the use of this
corrosion inhibitor, over time to bring the lead levels down.
So we continue to work very closely with EPA and our
customers. We are very much aware of the current issues. We are
very concerned by them, and we are doing everything that we
can, and we appreciate the support of EPA and our customers to
get us to a position where the corrosivity of the water is
reflected in results below the action limit.
So let me stop there, please, Mr. Chairman, and respond to
any questions in due course.
[The prepared statement of Thomas P. Jacobus follows:]
Prepared Statement of Thomas P. Jacobus, General Manager, Washington
Aqueduct, Baltimore District, U.S. Army Corps of Engineers
Good Morning, Chairman Gillmor and members of the Committee. I am
Tom Jacobus, the General Manager of Washington Aqueduct.
We appreciate the opportunity to be here today to report to this
committee the actions Washington Aqueduct is taking and the progress we
are making to reduce the elevated concentrations of lead in the
drinking water found in some homes in the District of Columbia.
Corrosion control has always been an integral part of the water
treatment process. After the Lead and Copper Rule was promulgated in
1991, Washington Aqueduct, based on the recommendations of its
consultant and in coordination with its wholesale customers, i.e., the
District of Columbia, Arlington County, Virginia and the City of Falls
Church, Virginia, conducted studies to determine the optimal corrosion
control treatment that would meet the requirements of the rule.
Corrosion control based on maintaining a target pH of the finished
water through the use of granulated lime was the recommended technique,
and after a series of reviews and discussions, Region 3 of the United
States Environmental Protection Agency approved that strategy.
Washington Aqueduct has paid very close attention to meeting the
chemistry required by the optimal corrosion control treatment
designation, and results from samples drawn from the customers' water
validated the effectiveness of the process for many years.
However, in 2002 the District of Columbia Water and Sewer
Authority's sampling under the provisions of the Lead and Copper Rule
produced results that exceeded the action level for lead. That
triggered the replacement of a percentage of their lead service lines.
These results also led the Environmental Protection Agency to begin a
review of the situation. Washington Aqueduct participated in this
review by supplying water quality data to the Environmental Protection
Agency's contractor conducting this investigation.
In November 2000, Washington Aqueduct added chloramines as a
secondary disinfectant to come into compliance with the newly
promulgated Stage I, Disinfectants, Disinfection Byproducts Rule. In
making that conversion, Washington Aqueduct and its consultants did
extensive research into potential side effects of using chloramines. As
a result, we took steps to watch for nitrification in the distribution
system that could reduce the pH of the water and consequently increase
the corrosiveness of the water. We saw no evidence that the new
chloramine disinfection process was increasing the corrosiveness of the
water via the nitrification process. The chemistry change did, as
expected, result in significantly lower levels of disinfection
byproducts.
However, the lead concentrations found among a large number of
samples collected by the District of Columbia Water and Sewer Authority
in 2002 and 2003 did indicate that Washington Aqueduct's optimal
corrosion control treatment that had previously been working
successfully to prevent leaching of lead from service lines was no
longer giving adequate protection.
Since February 2, 2004, our highest priority has been to reevaluate
the corrosion control treatment we use to protect the end users of the
drinking water in the District of Columbia and Northern Virginia from
the naturally corrosive effects of the water and to develop a treatment
modification to make the water less corrosive.
A Technical Expert Working Group consisting of Washington Aqueduct
and its consultants, the Environmental Protection Agency, the District
of Columbia Water and Sewer Authority and its consultants, the District
of Columbia Department of Health, Arlington County, Virginia and the
City of Falls Church, Virginia, was established to assist Washington
Aqueduct develop a new corrosion control treatment strategy.
Incorporating advice from the Environmental Protection Agency's
independent peer review panel, we have selected a new corrosion
inhibitor chemistry based on an orthophosphate compound and have begun
to install equipment that will be used to modify the corrosion control
treatment in a way that we believe will reduce the concentrations of
lead in drinking water that remains in contact with lead pipes, lead
solder joints and fixtures. This will go into place even as lead
service lines are being replaced.
In arriving at this treatment change, we have had access to the
nation's very best scientific and technical talent in this field. We
appreciate the resources that the Environmental Protection Agency has
expended to assist not only us but also to look at the larger aspects
of this issue.
In the process of doing this, we have worked closely with our
wholesale customers in the District of Columbia and Virginia, our
colleagues in the departments of health in the District of Columbia and
Virginia, and the United States Environmental Protection Agency. We
have also participated in many meetings throughout the District of
Columbia to explain to the residents the nature of the problem and our
approach to a solution.
A partial system application of the phosphate-based corrosion
inhibitor in a portion of the District of Columbia Water and Sewer
Authority distribution system began on June 1, 2004. In mid-August we
will begin a full system application that will include not only the
District of Columbia but the Arlington County and the City of Falls
Church distribution systems in Virginia as well. We are approaching the
application in two steps to be able to carefully control and evaluate
the initial application to ensure that the programmed dose of the
inhibitor does not generate any unexpected secondary effects. One known
possible effect of the application of the corrosion inhibitor may be
the localized release of rust from iron pipes. This would result in
discolored water delivered to the consumer, but it will be short-term
phenomena and can be managed by flushing the distribution system mains
as needed. So far in the partial system application no discolored water
has been observed at the customers' taps.
As part of our conversion to a corrosion inhibitor, we will be
installing a series of lead pipe loops made of pipe removed from
service in the District of Columbia Water and Sewer Authority
distribution system. They will simulate conditions in the lead service
lines still in the distribution system under a variety of scenarios.
These loops will be the basis of scientific studies over the next year
to evaluate the effectiveness of the treatment change as well as to
optimize chemical dosage and types. All of this information will be
shared with the water utility industry, the scientific community, and
the public to add to the knowledge base on corrosion and corrosion
chemistry.
This concludes my testimony. I will be happy to respond to any
questions.
Mr. Gillmor. Thank you very much, Mr. Jacobus. And I also
want to congratulate you on hitting the 5-minute time limit
almost exactly.
Let me now go to Jerry Johnson, who is the Executive
Director of the District of Columbia Water and Sewer Authority.
STATEMENT OF JERRY N. JOHNSON
Mr. Johnson. Good morning, Mr. Chairman, members of the
committee. I am Jerry Johnson, General Manager of the District
of Columbia Water and Sewer Authority. And on behalf of the
Authority, I would like to express our appreciation for the
subcommittee's interest in this matter.
Lead in drinking water is a serious interest and concern to
the Board of Directors, to me as an individual, our managers,
and every employee of the Authority, as well as our customers.
And I also recognize that it is a matter that concerns
policymakers in the Federal, State, and local level.
Among our many obligations, such as strong stewardship of
the environment and responsible management of ratepayer
resources, we take the obligation to distribute clean, safe
drinking water as our most important mission. I would like to
provide the committee a very brief update on our activities
since February of this year.
We have responded to 67,448 customer calls and e-mails,
distributed 36,900 water test kits. We have distributed 38,276
water filters, and continue to provide these filters
automatically to homeowners whose test results exceed, on
second draw, EPA action level of 15 parts per billion.
We have also hosted nearly two dozen community meetings and
participated in well over two dozen meetings hosted by
community organizations. We have videotaped two TV cable
programs, done bi-weekly news briefings, conducted nearly 7,000
blood lead tests in the District of Columbia, and in the
conduct of those--an analysis of those lead tests, we found no
relationship between elevated lead levels and lead in drinking
water in the District of Columbia. And, thus, it concluded that
we have not experienced a health crisis, but, rather, a major
communications issue in the District.
As you know, there have been several external reviews that
have been undertaken with the purpose, in whole or part, of
evaluating the Authority's performance under the lead and
copper rule. And we have recently received an audit that
extended back to 1998 by the U.S. EPA, and was conducted and
concluded with a consent order with a number of specific
actions, many of which were already planned and/or underway.
Some of those include committing to commit timely report--
submit timely reports to EPA using language that is required in
public educational materials, submitting plans to EPA for
public education programs, replacing additional lead service
lines in public space over the next 2 years.
This agreement, in its last instance, is a result of EPA's
conclusion that had water quality operation interpreted the
rules for submitting samples appropriately, and done the tests
differently, then the District would have exceeded the action
level a year earlier.
The Authority's Board of Directors has expressed some
reservations about the consent order. And as it does not
address the quality of Federal oversight, and specifically
feels that there was failure to provide timely notice of
deficiencies of the Authority's program, and that EPA approved
several of the matters now deemed to be a non-compliance, and
other areas of non-compliance, WASA sought and received
guidance from EPA.
The Board supported the agreement, however, because it
believes that the agreement brings to closure past issues and,
like the community pledge, it reflects the focus on the future
without imposing unnecessary costs and financial penalties--an
unfair burden on the ratepayers.
On July 16, the report of the Board of Directors of an
investigation conducted by Eric H. Holder, Jr., former U.S.
Assistant Attorney General, was released to the public. Mr.
Holder found that WASA staff made mistakes, and that they were
not sufficiently supervised, and that WASA's management made
decisions to downplay some of the lead monitoring related
issues as we went to public communication. These matters have
been corrected.
The report, however, goes further and generally WASA--that,
generally, WASA kept EPA informed of the many issues, but EPA
provided inconsistent responses and failed to raise sufficient
concerns. And other agencies involved in the water quality
issue, to include the Health Department, had muted responses
after learning of the exceedances.
With respect to resources, WASA will allocate the entire
Federal revolving loan grant of $11 million to the District for
the lead replacement program. For 2004, the entire cost of the
program, including capital support for the Department of Health
and outreach, was approximately $40 million.
Acknowledging that the Washington Aqueduct is proceeding
with plans to attack this problem at its source by adjusting
the chemistry and treatment process, the Board of Directors
went much further and voted to physically replace all of the
city's lead service lines and pipes in public space by
September of 2010, at a cost of just over $300 million.
Part of the community water pledge is to enhance
partnerships with the community, including the private sector.
And as such, we will announce next week that a national
financial institution is launching a program of low interest
loans for low-income homeowners for replacement of the
privately owned portions of the lead service lines. In
addition, a public sector grant will be made available from
other sources to assist low-income residents in the District of
Columbia.
Although we have developed in recent months a stronger
partnership with the District of Columbia, Department of
Health, the Authority has taken additional steps to ensure that
we have access to expertise in both health risk information and
health risk communication.
We have engaged the George Washington University School of
Public Health in a very effective partnership to help better
understand the science behind the lead and copper rule and its
implications for public health. And we aware of no similar
relationship anywhere in the country between a water system and
a non-governmental health institution.
We have been working with the university to develop a
workshop on utility and public health--with utilities and
public health professionals to address questions that range
from identifying health risks, risk communication, simultaneous
compliance, on science and policy questions that arose in the
recent months on the lead and copper rule in order to assist
the rest of the Nation.
Mr. Chairman, I continue to believe very strongly that the
District Government and other responsible entities should look
very closely at the issues of primacy and further
responsibility for the production of drinking water in the
Nation's capital. It is not, from my perspective, a political
or philosophical issue, when all is said and done, but a very
important policymakers consideration of fundamental challenges
that ensure the residents that are served by these entities.
In closing, our latest action--the latest actions by the
Authority and the determination to learn the lessons of the
past signal that we are determined to rebuild customer and
public confidence in the District of Columbia Water and Sewer
Authority.
I thank you, Mr. Chairman, and the committee for your
attention, and will be pleased to respond to any questions you
might have.
[The prepared statement of Jerry N. Johnson follows:]
Prepared Statement of Jerry N. Johnson, General Manager, DC Water and
Sewer Authority
Good morning Mr. Chairman, I am Jerry N. Johnson, General Manager
of the District of Columbia Water and Sewer Authority.
On behalf of the Authority, I would like to express our
appreciation for the Subcommittee's interest in this matter.
Lead in drinking water is of serious interest and concern to the
Board of Directors, to me, our managers and every employee of the
Authority, as well as to consumers. It is also a matter that concerns
policy-makers in federal, state and local government.
Although the responsibility is shared with the Army Corps of
Engineers Washington Aqueduct and the Environmental Protection Agency
(EPA), here in the nation's capital, the District of Columbia Water and
Sewer Authority is accountable to our customers and to the public when
it comes to ensuring that drinking water is safe.
Among our many obligations such as strong stewardship of the
environment and responsible management of ratepayer resources, we take
the obligation to distribute clean safe drinking water as our most
important mission.
COMMAND CENTER UPDATE
I would like to provide the Committee a very brief update on our
activities since February.
We have responded to 67,448 customer calls and e-mails since the
beginning of February 2004.
As you may know, the sampling required by EPA under the Lead and
Copper Rule was as low as 50 households and is now 200 households
annually.
Our lead Command Center reports that we have received and
distributed 36,909 water test kits, and nearly 20,000 test kits have
been returned to us for analysis. We have analyzed and processed 18,683
customer water samples this year, and the first and second draw sample
test results remain consistent across all pipe materials with respect
to lead level concentrations.
As of July 21, we have distributed 38,276 water filters, and
continue to provide these filters automatically to homeowner's who
participate in the sampling program and whose test results exceed on
the second draw the EPA action level of 15 ppb.
AUDITS AND INVESTIGATIONS
There have been several reviews undertaken this year with the
purpose, in whole or in part, of evaluating the Authority's performance
under the Lead and Copper Rule.
This morning we are participating in our fourth Congressional
hearing on this topic. The District of Columbia Council has held eleven
hearings since February 2, 2004.
We have hosted nearly two-dozen meetings and participated in over
two-dozen meetings hosted by community organizations. We have also
taped two videos for broadcast on cable access television and
participated biweekly news briefings in our effort to keep the public
informed.
The Interagency Task Force Chaired by Mayor William's and
Councilmember Carol Schwartz and the EPA audit have concluded.
CONSENT ORDER SUMMARY
The EPA audit extended back to 1998, and was concluded with a
consent order that included specific activities that were either
planned or already underway.
Under the settlement agreement we have reached with EPA which our
Board ratified, the Authority agreed to take steps, such as:
Committing to submit timely reports to EPA and use required language
in public education materials;
Submitting plans to EPA for--
1. our public education program
2. encouraging homeowners to submit lead sample tests, particularly
those who have had partial service line replacements
3. continuing our priority replacement program, and
4. encouraging private side replacements by homeowners;
Replacing an additional 1,615 service lines in public space in the
next two years.
This last item is the result of EPA's conclusion that had our
former water quality manager interpreted the rules for submitting
sample tests to EPA differently, and a small number of additional
sample test results had been included in the period from 2000 to 2001,
then the District would have exceeded the action level a year earlier.
In reaching a settlement agreement with EPA on the next phase of
the Lead Services Program, we are very pleased to bring a very labor
intensive and backward-looking review process to a close.
BOARD OF DIRECTORS RESOLUTION ON CONSENT ORDER
The Authority's Board of Directors expressed some reservations
because the consent order does not address the quality of federal
oversight.
The Board supported this agreement because it believes that the
agreement brings closure to past issues, and like the Community Water
Pledge, it redirects the focus to the future.
However, the Board did express in the clearest terms its
disappointment in the Environmental Protection Agency's failure to
``conduct routine and basic oversight of the Authority from 1998 until
the Compliance Audit commenced,'' on or about February 8, 2004.
The Board further noted that as a result:
That the EPA failed to ``provide timely notice of any deficiencies in
the Authority's Lead and Copper Rule program, including its
sampling program, public education program reporting forms and
time frames for reporting;'' and;
``EPA had approved several of the matters deemed to be in
noncompliance and for other areas of noncompliance WASA had
sought and received guidance from the EPA and proceeded on a
course of action with EPA's active consultation.''
However, this agreement, which did not impose any financial
penalties that would unfairly burden our ratepayers and ensured that
the EPA's review would not be open-ended, serves the best interests of
our customers and the general public.
Still underway are reviews by the District of Columbia Inspector
General, and, as you know, the Government Accountability Office.
HOLDER REPORT
Most recently, On July 16, 2004, The Report to the Board of
Directors on an Investigation conducted under the direction of Eric H.
Holder, Jr., a partner with Covington and Burling and a former United
States Assistant Attorney General, was released to the public.
It is the broadest comprehensive report, to date. It is critical of
WASA's management, in some instances. However, it is also critical of
other agencies involved in ensuring appropriate implementation of the
Lead and Copper Rule.
This investigation was undertaken on behalf of WASA's independent
Board of Directors. WASA's executive management and all staff
cooperated fully with Mr. Holder by providing tens of thousands of
pages of documents and thousands of e-mails. We sought to honor all
requests for personal interviews, including a number not initially
listed as part of the investigation. This was not the case with any of
the other organizations involved.
I am continuing to digest the Report fully, but it seems generally
consistent with my assessment of how WASA, the EPA, the Washington
Aqueduct and the District of Columbia Department of Health each handled
lead leaching from some homes' lead service lines, as well as some
elements of our responsibility to communicate with the public.
Mr. Holder finds that WASA staff, principally, the WASA Water
Quality Manager (Seema Bhat) and her supervisors made mistakes, and
that they were not sufficiently supervised; and that WASA's management
made decisions to downplay some lead monitoring-related issues in its
public communications.
The Report, however, goes much further, specifically stating:
WASA generally kept the EPA informed on many of the issues discussed
below, but the EPA provided inconsistent responses and failed
to raise significant concerns . . .''
``Other agencies involved in water quality issues--the EPA (and
Department of Health)--had a muted response after learning of
the exceedance . . .''
The requirements of the LCR do not effectively ensure public
awareness of the potential public health issues . . .''
SUMMARY OF INFORMATION PROVIDED TO THE SUBCOMMITTEE
On March 15, 2004, the Subcommittee requested information on lead
levels in the drinking water and the Authority's actions taken in
response to exceeding the EPA action level.
As you know, Mr. Chairman, our responses were fairly lengthy, but I
would like to briefly summarize them for the Subcommittee:
There was a very small annual lead service replacement program in
the District that ranged from 0.5% to 1.5% of the lead service line
inventory from 1992 to 1997.
At the time the District exceeded the action level in 2002, the
best source of information regarding the inventory of lead service
lines was the Weston Report, commissioned in 1990 for the District of
Columbia Government (Weston's analysis is based upon known lead
services, the proximity of other residences to known lead services and
installation date.)
Despite the fact that we have undertaken strenuous efforts to
reconcile and update pipe material records, some of which date back to
the turn of the last century, Weston remains the best source of
information.
WASA will allocate the entire federal revolving fund grant, $11
million, for the District to the lead replacement program, but we have
only used local ratepayer funds prior to that time. For 2004, the
entire cost of the program, including capital, support for the DC
Department of Health, and outreach, is approximately $40 million.
With respect to communications, WASA submitted plans for our
response to the EPA, which were followed by standard activities
including public service announcements, a bill notice and a bill insert
(EPA has noted the omission of use of ``significantly'' and
``unhealthy'' in some of these notices.)
The Authority also began the physical lead service replacement
program, launched the largest water sampling program ever undertaken in
the United States, and established a Hotline to help manage customer
communications more effectively.
The Authority policy was and is to notify customers of test sample
results within 30 days, but we acknowledge that efforts to fine tune
the information provided to customers in 2003 (6,111 samples) and the
sheer volume of samples in 2004 (18,683 to date) made meeting this
objective for every household problematic at times.
In the fall of 2002, following the trigger of the action level,
there were discussions among EPA, the Aqueduct, and the Authority
regarding a study of the optimal corrosion control methodology and why
it was no longer being achieved.
WASA and EPA sought the involvement of external expertise. Dr. Mark
Edwards, Virginia Polytechnic and State University, was hired by the
EPA. WASA retained Camp, Dresser and McKee, a consulting, engineering
construction firm, to support WASA's involvement in the project and to
help evaluate the findings produced by other parties.
The lead profiles that have been used to reevaluate the EPA
flushing recommendations as they relate to the District of Columbia,
are an example of a product of this work.
Early this year, these experts focused very intensively on this
effort, and they are now referred to as Technical Expert Working Group.
Its work has resulted in the Washington Aqueduct proposal to add
orthophosphate in the treatment process for the District in an effort
to re-optimize the corrosion control process.
As you may know, orthophosphate was added as a demonstration
project to a small part of the distribution system in the northwest
quadrant the week of July 1.
We are also pleased to report that we have received, to date, no
customer calls regarding the appearance of ``red water''--the potential
side effect of the application of orthophosphate. Pending EPA approval,
orthophosphate could be added to drinking water for the entire system
by mid-August.
In order to inform customers of the Aqueduct's planned application
of orthophosphate across the entire system, WASA plans to join with the
Washington Aqueduct, the Department of Health and EPA, in informing the
media and participating in Technical Expert Working Group community
meetings.
WASA has also been using our customer newsletter, reaching out to
our 125,000 metered customer addresses on the application of
orthophosphate over the past few months.
We will also distribute direct mail to every address, update our
web page, update Authority ``Interactive Voice Response'' (our on hold
messages), as well as update our customer service and Lead service
Hotline representatives to effectively respond to customer questions.
CHLORINE--UNEXPECTED CONTRIBUTOR TO CORROSION OPTIMIZATION
The Authority's initiative in monitoring lead level concentrations
during the period from April to May revealed during the annual switch
from chloramines to Chlorine revealed that lead level concentrations
had dropped by approximately 30 percent.
The finding suggests that chlorine may have had an unexpectedly
strong and positive impact on the corrosion control technology, pH
adjustment, previously designated by the EPA in 2000.
Studies are continuing, but the challenges associated with
simultaneous regulatory compliance, and the lack of national research
on its challenges, have moved closer to the center of this discussion.
BOARD ACTION AND WASA COMMUNITY WATER PLEDGE
Acknowledging that the Washington Aqueduct is proceeding with plans
to attack this problem at the source by adjusting the chemistry and
treatment process, the Board of Directors went much further and voted
to physically replace all the city's lead service line pipes in public
space by September 30, 2010.
Also recognizing that any major infrastructure program can be
disruptive, WASA management is committed to also go well beyond the
requirements of the law in how we communicate with the public.
Consistent with our Community Water Pledge, we will work to meet
the expectations of our residents in communicating clearly and in
advance to help minimize any disruption and inconvenience by:
1. Issuing a calendar of planned replacements by block and/or
neighborhood
2. Contact customers scheduled for replacement individually by letter
3. Place a door hangar on homeowners' doors
4. Contact customers who are part of the replacement program at three
intervals: 45-days, 7-days and 48 hours before construction
5. Participate in or host a community meeting in neighborhoods in
advance of construction
6. Provide a WASA contact name and number for questions and complaint
resolution.
Part of the Community Water Pledge is to enhance our partnerships
in our community, including those with the private sector.
Two weeks ago, we joined Mayor Williams at his weekly press
briefing to announce a growing partnership with the private sector--the
General Electric Corporation has donated 12,500 filters to the lead
services program, joining PUR and Brita who made earlier donations.
As you may know, the Lead and Copper Rule and EPA mandate that we
offer homeowners the opportunity to use our contractors to replace the
private side of lead service lines for as long as the District exceeds
the Action Level.
As part of our Community Water Pledge, we expect to announce as
early as next week that a national financial institution will launch a
program of low interest loans for low-to-moderate income homeowners for
the purpose of replacing the privately owned portion of lead service
lines. Grant funds will also be made available from another source to
assist low income District residents.
Although we have developed in recent months a stronger partnership
with the District of Columbia Department of Health, the Authority has
taken additional steps to ensure that we have access to expertise in
the areas of both health risk information, and health risk
communication.
We have engaged the George Washington University School of Public
Health in a very effective partnership to help us better understand the
science behind the Lead and Copper Rule and its implications for human
health.
This strong partnership is helping us to communicate this
information more effectively to our customers and the general public,
and we are aware of no similar relationship anywhere else in the
country between a water system and a non-governmental health
institution
INDUSTRY WORKSHOP PLANNED
We have been working with the University to develop a symposium or
workshop for utility and public health professionals in the very near
term to examine lessons learned from our experience.
This workshop, which we hope will involve some of the most
effective and strongest voices in the industry, will address questions
that range from identifying health risks appropriately and risk
communication, to simultaneous compliance and the science and policy
questions that arose in recent months around the Lead and Copper Rule
and its enforcement.
Under the Community Water Pledge, WASA has committed to take the
strongest steps to address the expectations of our customers, which far
exceeds the requirements of the US EPA. Each of the steps I have
outlined is ultimately intended to ensure that we live up to that
commitment.
There are, however, questions of policy that do not specifically
relate to the Lead and Copper Rule, itself. I believe they may be
central to understanding the recent experience in the District of
Columbia.
A UNIFIED WATER SYSTEM AND PRIMACY
Mr. Chairman, I continue to believe very strongly that the District
Government and other responsible entities should look very closely at
the issues of primacy and the future responsibility for water
production for the nations capital.
This is not from my perspective a political or philosophical issue.
When all is said and done, it is important that policy-makers consider
fundamental challenges, such as ensuring that residents are served by:
1. the best structure for the most effective and seamless operation of
the water system;
2. a well-informed regulatory authority with a direct and clear
responsibility to serve the local community
3. clear lines of authority and public accountability to local
authorities.
A transfer of authority from federal to local government is no
panacea--there are no infallible systems, managers or processes, but
the question of unified management of the water system should be
thoughtfully and objectively considered.
Similarly, the issue of federal versus state and local regulation
and enforcement of the environmental regulations, in particular, are at
the heart of the goals of the Safe Drinking Water Act.
CONCLUSION
In closing, the latest actions by our Board of Directors, including
its commissioning and receipt of the Holder Report, and the Authority's
determination to learn the lessons of the past and put them to use on
behalf of our customers all signal that with respect to governance,
management, the sampling program, customer communications and physical
replacements, we are determined to rebuild customer and public
confidence in the District of Columbia Water and Sewer Authority.
Thank you for your attention, Mr. Chairman. I would be happy to
respond to any questions.
Mr. Gillmor. Thank you, Mr. Johnson.
The gentleman from Idaho, Mr. Otter, has requested
unanimous consent that his opening statement be entered into
the record. And without objection, hearing none, so ordered.
We will begin with our questions. I would like to start,
Mr. Grumbles, with a question for you. Your testimony states
that EPA is reviewing the actions taken by all parties to
ensure that we use the lessons learned to prevent such an event
from taking place in the future.
Now, this review comes on the heels of the EPA revising
monitoring, reporting, and public education requirements in
2000, so a number of questions relating to that. Since you have
revised the rule, what lessons have you learned that the rule
did not already contemplate? And what have you done differently
in Boston, in Portland, in Seattle, that you did not do in
Washington, DC? And perhaps, most importantly, does Congress
need to act in any way to support your efforts?
Mr. Grumbles. Mr. Chairman, I will try to respond to each
of those questions as best I can. First of all, on the lessons
learned front, I would say that you can't put a high enough
price on the importance of accurate, timely, useful, and
reliable information to the public. Now, EPA did, in 2002,
pursuant to the rule, develop some additional public education
guidance.
But we learned, and are continuing to see, that the more
robust and the more specific and useful the information the
better. And a lot of it is emphasizing the tools of risk
communication and using multiple media markets and mass media.
But one of the key lessons learned is you can make a bad
situation much worse by not coming forth early and
communicating effectively.
And I think that is certainly one component, and I think a
key component that will facilitate that is making sure that the
individual homeowners, those who do have lead service lines,
know the situation, know what is going on, could get some type
of information. And I think that as we look at some of the
cities that have experienced this problem, that is one of the
lessons we can glean from their experiences is getting more
information out to the public, and certainly to the States who
are primarily the ones overseeing the lead and copper rule.
But from an EPA perspective, one of my top priorities is
really digging in deep and looking very carefully at the
monitoring and reporting and public education, public
notification components of the rule.
Mr. Gillmor. Thank you.
Let me go to you, Mr. Johnson. The DC Office of Inspector
General issued a followup management report on WASA dated
January 7, 2002, that stated that in tests performed by WASA 20
percent of the employee drinking water fountains at the Blue
Plains facility exceeded Federal limits.
Now, the IG stated that combination appeared to be
attributed to either the pipe leading to the water fountains or
the plumbing behind them. The IG report also included an
employee complaint that yielded tests showing the water level
to be 400 percent higher for lead than the Federal standard.
How could a report like that just fall through the cracks?
Mr. Johnson. Actually, Mr. Chairman, it did not fall
through the cracks. We determined at the time that that report
was done that we had a number of fixture problems internal to
the facilities there. I believe that in the mid 1990's there
was a recall of a number of different types of water fountains
in the United States, and we determined that at that time those
fountains had actually not been replaced. Those fountains were
then replaced. We have done--conducted a series of tests since
that time, and the results have come back negative.
Mr. Gillmor. Thank you.
We will go to the gentlelady from California, Ms. Solis, if
she has any questions.
Ms. Solis. Yes. Thank you so much, Mr. Chairman.
My question is to Mr. Grumbles from EPA, and I thank you
for taking the opportunity the other day to come by my office
and sit down and talk to us.
I just had--I have several questions, but I wanted to go
back to something you said earlier regarding data that you are
currently reviewing or have reviewed from the different States
that has been submitted to you. You mentioned that they are
about 90 percent in compliance, the materials that you have
received, say, from the various States regarding their
compliance level.
Mr. Grumbles. And we have this all up on our website. So if
I say something that is incorrect, not only will I correct it
for the record, but I also encourage people to visit the
website. And it is a very important question for clarification.
We have gotten about--I think 89 or 90 percent of the
systems we have gotten data from them on their 90 percentile
information. And so the key, in looking to see if you are
complying and following the major aspects of the lead and
copper rule, is this so-called 90th percentile. And that is so
important, because that is what in a community when they are in
the testing and monitoring for lead in drinking water, the way
the rule is written it spells out that, if you do 100 samples,
you look at the 90th percentile and see whether or not that
sample is--exceeds 15 parts per billion.
And what we have found--what we have found in extensive
review and getting virtually all of the data from the country,
the States, and their systems in the States, is that it is a
less than 4 percent of the--less than 4 percent of those
systems are exceeding that all-important 15 parts per billion.
Ms. Solis. Okay. My question is: when did you request that
compliant information from the States? When did that go out?
When does that notice go out?
Mr. Grumbles. Well, there are a couple of things going on.
One is we sent notice to the EPA regions and the States
probably about 3 months ago, or in March of this year.
Ms. Solis. Around the time of the DC----
Mr. Grumbles. Well, yes. One of the--the rule requires
systems to report their data to their States. That is what the
1991 rule says. But as we were discovering, the scope of the
situation here in the District of Columbia, the first thing
that we wanted to do as the head of the national water program
was to get as much data as we could, specifically send out a
separate request for information from all of the systems from
the States to see how they were doing on that 15 parts per
billion.
Ms. Solis. So is it, then, a response to what happened in
DC that you asked the States, then, to come up with this
information?
Mr. Grumbles. I would say unabashedly that our national
compliance review was a response to the scope of the problem we
were discovering----
Ms. Solis. Okay. My----
Mr. Grumbles. [continuing] in the District.
Ms. Solis. Okay. Great. My next question is, I understand
all of this is self-reported, and you have different
individuals that are involved in compiling that information. In
the State of California, were there any problems with looking
at its data and being able to kind of piece that together to
better understand what is happening in our State, because it
have different systems that may not all speak the same there?
Mr. Grumbles. I think you have identified a challenge that
we, as information managers, face in various parts of the
country, or in some of our implementation efforts under the
Safe Drinking Water Act, is making sure that the data systems
are compatible and talk the same language. And in California,
we are spending additional time working with the State, so that
our data systems and their data systems, we can integrate. So--
--
Ms. Solis. Well, some of that information may not be as
conclusive and accurate, because of those discrepancies.
Mr. Grumbles. Well, we want to make sure we get all of the
data in, and that there aren't discrepancies. But I think we
have got a pretty good--we have a pretty good picture of the
overall question nationally.
Ms. Solis. And is that on your web page, information----
Mr. Grumbles. Yes.
Ms. Solis. [continuing] from California? So we can look at
that and all of the other States as well? But it is not all
complete. It is not all complete.
Mr. Grumbles. It is not all complete. It is getting very
close to that picture.
Ms. Solis. Okay.
Mr. Grumbles. We wanted--in the interest of speed, without
sacrificing quality, we wanted to get up as much information as
we could, because people want to know, is this a national
problem? How pervasive could it be?
Ms. Solis. My next question very quickly, on April 12,
2004, Mr. Dingell and I wrote to Administrator Leavitt and
asked why President Bush's budget for FY2005 did not contain
any funding to implement the New York Watershed Program. As
Acting Administrator, can you explain why the President's
budget did not seek funding for the New York Watershed Program?
Mr. Grumbles. Well, I can certainly express two things. One
is is that the administration is fully supportive of the
overall New York City watershed effort and the important
message of source water protection to help protect the drinking
water and also reduce the costs of treatment downstream.
I can also say that, as the appropriations committees are
familiar with, there are priorities. And one of the
administration's priorities is to put $850 million into the
drinking water State revolving fund and to be committed to
doing that through the year 2018. And that way money can go
through the States, and the States can identify their intended
use plans and develop their priorities.
Ms. Solis. Wouldn't it have been better served had the
administration initially requested the $850 million up front?
Mr. Grumbles. We have been requesting the $850 million up
front. On the State revolving funds, it is something that we
have been doing over the last several years, and Congress has
been appropriating that. And our point is that, yes, there are
billions of dollars in needs across the country. A constructive
Federal role for the EPA is to provide $850 million, if
Congress appropriates it, for the State revolving funds.
And then, through that, the States then get--then use those
funds, in addition to other drinking water grant programs, to
address----
Ms. Solis. For outreach?
Mr. Grumbles. For outreach and to address specific----
Ms. Solis. That might help Washington. That might help the
District to provide information and prevention that is sorely
needed. I mean, just to hear that the contaminant levels are so
very high, and have yet to actually come to light, some of the
other areas in the District that need to be tested around, say,
the naval yards, those are very disturbing statements. And I
think they do require some immediate action and relief on the
part of EPA, and, obviously, the Water Authority as well.
So I will end with that. I think my time is up.
Mr. Gillmor. Your time is up, yes.
Ms. Solis. Thank you, Mr. Chairman.
Mr. Gillmor. The gentleman from Idaho, Mr. Otter, do you
have any questions?
Mr. Otter. Well, thank you very much, Mr. Chairman. Yes, I
do.
Let me first begin by thanking Mr. Grumbles for coming by
my office, and even though we had a vote on it I didn't get to
discuss some of the things that I wanted to. I do feel that
there is a glimmer of hope for Idaho and other places in how we
are treated out there by Region X.
And I really hope you stay engaged in that, because I have
absolutely no hope that Seattle is going to solve our problems,
or is even sensitive to our problems. And we can't get it out
of Washington, DC, then I don't know what we are going to do.
Let me--I would ask you one question about--is there any
relationship between the water quality that we are talking
about now and the EPA's 6-year permit that they granted to the
Army Corps of Engineers 2 years ago to dump 200,000 tons of
sludge into the Potomac River? Is there any relationship
between those two?
Mr. Grumbles. You know, Congressman, from an overall
watershed basis, a lot of things are connected in terms of the
Clean Water Act and Safe Drinking Water Act, and a priority of
the agency is to help integrate so that the tools for source
water protection and the funds for drinking water and clean
water programs are effectively used, and that we, as managers
and regulators, look at the issue holistically.
But I would defer to Don Welsh. He is the Regional
Administrator who is the regulatory entity overseeing the
specific facility questions that you just asked.
Mr. Otter. Mr. Welsh, are you familiar with the permit that
was issued to the Army Corps of Engineers for the dumping of
that sludge into the river?
Mr. Welsh. Generally, yes, sir.
Mr. Otter. Am I correct, was it 200,000 tons?
Mr. Welsh. I don't know the exact number.
Mr. Otter. Was it an annual permit? So they are allowed to
do this every year?
Mr. Welsh. They are permitted to discharge the sludge that
is removed from the water, the----
Mr. Otter. Sediments.
Mr. Welsh. The raw water that they bring in to treat for
drinking water has a lot of sediment in it. And as part of the
treatment process, they settle that sediment out of the raw
water.
Mr. Otter. Would there be suspended lead that would settle
out of that--lead that had gone into the solution?
Mr. Welsh. I don't believe so, and it is also that the
discharge point for that sediment, going back into the river,
is below the drinking water intake. So it is not a question of
that recycling into the system and somehow exacerbating this
lead problem.
Mr. Otter. I see.
Mr. Welsh. And we have recently done a new permit for the
discharge of that material, and it is not discharged during the
spawning season, which was one of the concerns when we were
going over the new permit. So even though there continues to be
discharges, they are less frequent and more controlled than----
Mr. Otter. That is the habitat of an endangered species
called the stub-nosed sturgeon, is that----
Mr. Welsh. Short-nosed sturgeon.
Mr. Otter. Short-nosed sturgeon. Out in Idaho, short and
stub is about the same.
Mr. Welsh, the Covington and Burling report commissioned by
the WASA mentioned that the EPA Region III was initially
resistant to allowing WASA to simply test its water lines for
lead levels, rather than replace them in order to meet the 7
percent replacement requirement under the Federal rule. Why did
Region III allow this change in enforcement?
Mr. Welsh. Yes, sir. We did see that in the report as well,
and our staff doesn't recall being resistant to it. We may have
mentioned that it would be preferable to do actual removals
rather than testout, but----
Mr. Otter. Mr. Johnson, do you agree with that?
Mr. Johnson. Well, I think the findings of the report are
accurate, and I am not absolutely certain where they may have--
who they may have interviewed or where they got the
information. My understanding was that all of the responses
that were provided from the United States Environmental
Protection Agency were in writing, so there should be some
documentation of that.
Mr. Welsh. And the rule does contemplate testout, so we
were asked if they could do that and reviewed the rule and gave
them the answer that that was permissible in the rule.
Mr. Otter. From March 26, Mr. Welsh, to April 6 of this
year, samplings at DC Public Schools had identified 43 drinking
water fountains and sinks with excessive levels of lead. In
fact, one of them was 7,300 parts per billion, which is 486
times the Federal lead action level.
Recognizing the impact that has been generally accepted,
the impact that it has on young minds, why wasn't the--what is
the EPA--what is Region III doing to eradicate that problem?
Mr. Welsh. When we first began grappling with the situation
of the high lead levels, we did direct that testing according
to EPA protocols take place in the DC Public Schools. They did
the testing, and that is what identified the number of fixtures
that you mentioned that were exceeding the standard.
DC did immediately take those fixtures out of service, so
that the population of concern wouldn't be exposed to drinking
water from those fixtures. We also directed that they do
sampling of independent schools, daycare centers, nursing
homes, to get the same kind of information about those types of
facilities that were other than the DC Public Schools, and they
have recently received data back from that. There were a number
of those that were exceeding the level, and their guidance is
being sent to take them out of service.
So the immediate concern is to make sure that the sensitive
population doesn't continue to be exposed to water with
elevated lead levels, and DC was very responsive in removing
those fixtures that did test high from use.
Mr. Gillmor. The gentleman's time has expired.
The gentlelady from Illinois?
Ms. Schakowsky. Yes. Mr. Grumbles, one of the problems with
the lead and copper rule that appears ripe for a solution is
that a drinking water system can test repeatedly to look for
lead lines that are not leaching, and can use those lines that
are found not to leach for credit, so that they can avoid
replacing lines that are actually leaching, thus leaving
families and children to drink water that exceeds those levels.
This unfortunate approach, it seems to me, provides exactly
the wrong incentive to drinking water systems and doesn't
protect the public health. So why would you wait before acting
to address this problem?
Mr. Grumbles. Well, I really appreciate you flagging that
and raising that issue, because that is one of the areas that
we really want to look at very carefully. We are going to have
a workshop, an expert workshop, on lead service line
replacement, but the issue you are raising about the 7 percent
requirement and the ability to test out or to back off the
number of lead service lines that actually get physically
replaced is one that requires a lot of review and scrutiny.
And I would say that that is one of the areas that we are
most interested in looking at for possible revision, either
through our guidance or through a regulation. And that is one
where we need to hear as well from the utilities. And, I mean,
they are under a lot of pressure to try to finance and come up
with a mechanism to actually carry out the intent of the lead
and copper rule, but I think you have identified one of the
areas that does benefit from some very----
Ms. Schakowsky. Well, let me just say that it seems to me
that this administration is moving more in that direction
rather than less. For example, with the mercury rules during--
dealing with air pollution that you can--that those standards
are lowered, and that you can buy credits in order to continue
to pollute the air, and in this situation you can actually
continue to provide--I mean, we want to see some action here
when we have these known contaminants that damage children so
extensively.
We know that already, and I hope that you will have a sense
of urgency about that in moving ahead. I mean, the fact that
you can have--I thought it is less than 8 percent, and it
counts as lead-free. Is that not true?
Mr. Grumbles. You are raising another issue that benefits
from both congressional and non-congressional conversation, and
that is the statutory provision that is in the Safe Drinking
Water Act that defines the acceptable percentage of lead in the
definition of ``lead-free.'' And it has been several years
since Congress enacted that provision, and that is one--that is
definitely on the table to review and to look at. We want to
engage--we want to get the views of NSF, we want to get the
views of the regulated community, but the public as well on
that precise question.
Ms. Schakowsky. Well, I should hope--actually, I would hope
that in some ways you would reverse the priority there, that we
are talking about the public interest. And while I understand
that the regulated utilities have issues here that clearly need
to be considered, that we begin from the point of view that
your job is to protect the public interest.
Mr. Grumbles. And that is where we begin----
Ms. Schakowsky. Okay.
Mr. Grumbles. [continuing] protecting public health and
making sure that the regulation protects the public health.
That is----
Ms. Schakowsky. I understand, and I hope you----
Mr. Grumbles. [continuing] that it is sustainable, that it
is implementable and workable. But that is an area that we are
looking very seriously at and look forward to working----
Ms. Schakowsky. Okay. Let me ask--bottom line, Mr. Johnson,
you distributed a number of--are they Britas, basically, that
you gave to people? Or do you put something on a faucet, or
what is it? And at what point can we turn on our waters--our
faucets confidently and just drink right out of them?
Mr. Johnson. There are responses to a couple of questions.
There are point-of-use devices manufactured by several
different companies, and they are a combination of both pitcher
filter devices as well as tap-mounted devices, and we have
provided filters for those devices to cover approximately 6
months of use. And we have now ordered enough to cover another
6 months of use, assuming that the orthophosphate treatment
will probably take about 6 months to a year to be effective and
get us below the action level.
I would submit, Madam, that in cases where we are talking
about the utilization of drinking water in any fixture in any
home anywhere that a few moments of flushing is probably
warranted. The fixtures that you just mentioned with the 8
percent allowance, that would have certain fixtures containing
lead, would certainly generate some, so I would--even if I was
in a new home, I think I would flush for a moment or so before
utilizing----
Ms. Schakowsky. How long is that?
Mr. Johnson. The current protocol for us, with a person
with a lead service line, is--we recommend 10 minutes of
flushing. That is approximately enough time to ensure that
water has moved through the lead service line and into the--out
of the fixtures and into the home. That is a once per day kind
of flushing after the water has been standing in the service
line for about 8 hours.
We would also recommend persons who don't have lead service
lines would flush for a moment, for a minute or so, just to get
the water out of those fixtures.
Ms. Schakowsky. Thank you.
And, Mr. Chairman, could I ask unanimous consent to put my
opening statement into the record?
Mr. Gillmor. Without objection----
Ms. Schakowsky. Thank you.
Mr. Gillmor. [continuing] so ordered.
The gentleman from California is recognized.
Mr. Issa. Thank you, Mr. Chairman, and I think I would like
to pick up on Ms. Schakowsky's starting point, because I am
very concerned here that in a sense we are seeing the tip of an
iceberg, and there may be a considerable amount more. But I
would like to just quick follow up.
How much water, if everyone follows your guidelines, will
we be consuming? And what is the cost of that water? If you
look roughly at 10 minutes to a big chunk of the city and the
area, another 1 minute to a bunch of others, I would assume
that we are talking about a lot of dollars being transferred
that could pay for lead pipe replacement that, in fact, is
simply being transferred to the consumer in hopes that they
reduce the impact of the lead that remains there.
Mr. Johnson. Well, I would address that in a couple of
ways. One is that there is a plan in place now for the
replacement of all lead service lines in public space by 2010,
which is a policy that was put in place by the Board, so that
addresses the issue as we deal with it over the long term, and
we have also worked with some financial institutions to put in
place some loans to take care of the private portion.
With respect to the water, the cost of water is something
less than .6 cents per gallon in the District. So if you had a
lead service line and you did that flushing twice per day, it
would probably cost you around $4 a month.
Mr. Issa. Okay. I just--so $4 a month times 100,000 homes,
it could be half a million dollars a month of expense
transferred to the water consumer if they all complied. Is that
just a ballpark figure?
Mr. Johnson. I am not--don't know that I am necessarily
following your math, but it would be logical that----
Mr. Issa. I am sort of looking at $4 a month. We certainly
have more than 100,000 affected places to be flushed, so
$400,000 a month. That is a significant amount of dollars.
Mr. Johnson. Actually, it is about 23,000 lead service
lines that are in the District that we would--that would fall
into that category. So it would be that number times $4.
Mr. Issa. Okay.
Mr. Welsh. May I add a small point?
Mr. Issa. Yes.
Mr. Welsh. I understand the importance of your concern, and
it is----
Mr. Issa. You know, I am a Californian, so water is much
more dear perhaps in our minds to--we fix leaky faucets in
California in order to not consume the water.
Mr. Welsh. I did just want to add that there are some non-
consumptive uses of water that can serve for the flushing
period. So if you are using the dishwasher or washing machine
in the house, you can use that period to flush the line, and so
you are getting the use out of that water that you would get.
So you can----
Mr. Issa. Okay. I appreciate it.
Mr. Welsh. [continuing] reduce it somewhat.
Mr. Issa. I appreciate that.
Mr. Johnson. And that is the direction that we have been
providing to the residents is to use some high-consumptive use
the first time in the morning.
Mr. Issa. I guess one of the most disturbing points here is
I agree with the minority side here that testing is extremely
important, and I don't think this panel would look down and say
replace blindly if testing can be the way to target those areas
that need to be hit first.
But I am concerned from the Covington and Burling report
that apparently WASA was able to just invalidate a significant
portion of the test. Now, if you are doing tests and you are
allowed to invalidate tests, then you can skew extremely, one
way or the other. Why is it that any tests are allowed to be
invalidated without each test being reviewed for how it is
going to affect the outcome?
I guess Mr. Welsh would be primary on this.
Mr. Welsh. The rule does contemplate invalidation of
samples, and there can be legitimate reasons why you may need
to invalidate a particular sample--if there was an error in the
collection of the sample, or the seal was broken. But the rule
does that in a specific sequence.
You need to request in writing that that sample be
invalidated, indicate what that sample is, what the reason was
for the invalidation, and get approval from the primacy agency.
In the case of DC, it would be us. In other instances, it would
be the State--to invalidate those samples for cause. So in this
case, there was never any written authorization for any
invalidation, so that procedure was not followed.
But you can contemplate circumstances where invalidation
would be appropriate, but you would also want to do followup
sampling at that source to make sure that----
Mr. Issa. Right. Have you been able to go back and find out
whether those samples that were not used, validated for
whatever reason, are random and thus probably having no
material effect, or in some way not random?
Mr. Welsh. Our review--when we did the compliance audit of
WASA, our review indicated that there were samples that were
taken but were not in the 50 that were reported for compliance
purposes to EPA for that sampling period. And had they been
included that WASA would have exceeded the action level under
the----
Mr. Issa. Sure, and I appreciate the outcome, that it did
have an effect. But the question was: was it a random error
that just happened to put WASA under the limit? Or should we be
investigating further whether persons or--a person or persons
in fact invalidated with, if you will, an intent to somehow
skew the results, which when we are talking about people's
health is a matter of great concern. At a minimum, that person
should no longer be in a position to trust, I think everyone
would agree.
Mr. Welsh. Our compliance review indicated that there were
samples that weren't reported, so we were able to see that
there was underreporting of samples. We hadn't--we did not
conclude in our enforcement action intent. It was difficult to
establish the information to figure out which samples and
cross-walking the different samples to establish that there
were--that there was data collected that wasn't reported to us.
But all that we have established is that there was data that
was not reported.
Mr. Issa. Okay. Last--it has to be asked--when we have a
finding of more than 400 times the allowable limit of lead from
a particular drinking fountain, how are we following up with
the affected, potentially affected persons, both immediately
and the ones who may have been drinking at these drinking
fountains in the 2 or 3 or 4 years in advance? Is there a
procedure to go after those who obviously are potentially at a
health risk when you have that kind? I understand if you have
30 parts per billion you may not do it, but at 400 times the
level, what are we doing?
Mr. Johnson. I can tell you what we have done in the
District of Columbia. When we got test results back, in all
cases where there was any test result that was more than 300
parts per billion, the Health Department was dispatched to that
particular home to request a blood lead test of all the
residents of that particular dwelling unit, or, in the cases of
schools, we sought permission from the parents of children who
were in the at-risk population, which is below the age of six,
to do blood lead testing.
And that has been done extensively throughout the District
of Columbia, and we have monitored those results, and those
persons who were involved in that testing.
Mr. Issa. And what happened?
Mr. Johnson. We have drawn the conclusion that--and we did
follow up from anybody who came in with blood lead levels that
exceeded 10 parts per--10 micrograms per deciliter, which is
the standard that is established by health officials.
Then, we did an environmental scan of each of the homes and
residences, did a series of interviews with the parents and/or
the affected adult, and in all cases we found--in every single
case where there was an elevated blood lead level we found that
there was something other than water that was contributing to
that problem in the environment. Either there was renovation
that was taking place at the home, there was lead paint in the
home, there was lead in soil that was around the home, the
parents worked in some environment which transferred lead from
their working environment to the home.
We did the same testing in daycare centers throughout the
District of Columbia as well.
Mr. Issa. Thank you, Mr. Johnson.
Thank you, Mr. Chairman. I think that was the most
informative of all the answers so far, and I look forward to
reading the rest of the record.
Mr. Grumbles. Mr. Chairman, could I----
Mr. Gillmor. Yes, Mr. Grumbles.
Mr. Grumbles. I just wanted to add to Congressman Issa--the
issue you raised about, what are we doing when we have such
high, extreme level exceedances, is one of the issues that we
are very interested in reviewing in terms of the current rule,
because it is one thing contemplating a response when there is
a 16 or 17 part per billion level.
There might be under consideration another more extensive
protocol or approach when there is 400 or 500 parts per
billion. And I just appreciate the point you were making about
water conservation. As we look for leak detection systems, we
find that communities, a small community in Pennsylvania, when
they went through a leak detection program, they weren't
flushing because of lead. They were just losing water in their
pipes.
They were able to save 50 to 60 percent of their water and
energy, their cost to run this, and the community benefited
from that. So I appreciate you making that point about water
efficiency and conservation.
Mr. Gillmor. Before I recognize the gentleman from Texas,
let me say we have a couple more questioners, and as we have
three panels, then we will have to close this one. But I do
sense that some members do have other questions. I would like
to ask the panel--Mr. Grumbles, Mr. Welsh, Mr. Jacobus, and Mr.
Johnson--if you would all be willing to answer in writing
questions that members may submit later.
Thank you very much.
The gentleman from Texas.
Mr. Green. Thank you, Mr. Chairman, and I would like to ask
unanimous consent to have my statement placed in the record.
Mr. Gillmor. Without objection, so ordered.
Mr. Green. An earlier hearing of this subcommittee dealt
with reauthorization of a portion of the Safe Drinking Water
Act, and from that testimony, if I can get it out, it talked
about the champagne of New York waters. And I think that is a
good followup to this one. I don't know what we would call our
DC waters that we are having to drink since New York and we
authorized for the champagne.
But, Mr. Grumbles, Mr. Ramaley of the Association of
Metropolitan Water Agencies testimony later will state that 5
percent of the Safe Water Drinking Act's funding goes to
metropolitan areas, but there are 20 percent of the Nation's
drinking water improvement needs.
And how can--what can we do, or what can you do, to assist
metropolitan areas like DC or Houston, for example, to prevent
public health situations such as what we have seen here? And do
we need to increase funding or increase focus on metropolitan
areas? Or is the status quo under the Safe Drinking Water Act--
is that fine with the EPA?
Mr. Grumbles. The status quo is not something that is fine.
I think our charge is to increase the velocity of environmental
progress and success in the Safe Drinking Water Act. Part of
the way to do that is to provide $850 million a year through
2018 for the drinking water State revolving funds that the
States can then use a prioritization plan to target those areas
that are in most need.
The other thing, Congressman, is to focus in on source
water protection and key areas. It is basically to follow the
needs urban areas have. EPA fully acknowledges that the
drinking water infrastructure gap is a very large one, and it
requires Federal funding, but it requires smarter approaches as
well, and State and local funding. It is not just water use
efficiency, which can be a tremendous tool in the toolbox for
urban areas, to have more efficient plumbing or to have pricing
mechanisms.
But it is also looking at better ways to integrate funding
programs under the Clean Water Act, Safe Drinking Water Act, so
your point about the urban needs and drinking water
infrastructure needs is a very valid one, and it requires
funding from all levels, and, more than that, some smarter
approaches about full cost pricing and asset management.
We have found that, and GAO has reported that, it may not
be a silver bullet, but the concept of asset management, being
able to go out and in a more systematic way--as many utilities
are doing in the country--can translate into significant
savings, and, therefore, less of a need for Federal funding
when funding is very tight. And it can involve doing things
like looking at which pipes--sometimes the oldest pipes aren't
the ones that need to be replaced the soonest, but things like
that we fully endorse.
Mr. Green. Well, I appreciate not only for the large
agencies like Washington or Houston, but I have a very urban
area with small municipalities that sometimes do not have the
tax wealth or the ability to do some of that. And we worked at
our EPA regional office now for the dozen years I have been in
Congress to see how we can do that and package that.
But you are right there is--and EPA does continue to
provide assistance to some of these authorities that make those
suggestions. Because of the resources going into large agencies
like Houston or Washington, they have the resources of some of
our smaller municipalities, even in urban areas, that need that
assistance that we get from oftentimes our State water
authorities, but also EPA.
Mr. Grumbles, you indicate in your testimony that EPA is
conducting a national review of the compliance and
implementation of the lead and copper rule. How long do you
estimate it will take to complete that review and its
recommendations?
Mr. Grumbles. We are committed to doing it right, to get it
done the right way, and that means that we don't want to
prejudge the outcome. I personally want to be able to have some
pretty clear ideas as to what possible areas we should revise,
like what types of guidance. I think there are some great
opportunities to provide clear or additional guidance.
In terms of the rule, how to--or whether to revise the
rule, I think we are developing some pretty specific detailed
lists. We do benefit from discussion from the public on a lot
of those issues, but my goal is to try to get as quickly as
possible, but in the right way, to a point where we can provide
some type of initial answer to that question: does the rule
need to be revised?
Mr. Green. Okay. It would appear that some issues may not
require survey before action is warranted. For example, we
understand that EPA staff--from EPA staff that EPA guidance is
more stringent than the lead and copper rule under public
communication requirements, and EPA is working on further
recommendations for additional guidance. Is that correct?
Mr. Grumbles. We are looking specifically at additional
guidance to provide greater direction for communities. That is
one of the areas that is a priority is developing additional
guidance, not waiting for a long array of public meetings but
moving forward in some discrete areas.
Mr. Green. Mr. Chairman, I appreciate--let me follow up
with, given the critical importance, particularly what happened
here in Washington, went under public communication, went under
the lead and copper rule, high lead levels are allowed to
remain in drinking water for extended periods of time. Why
wouldn't EPA require, as opposed to simply recommend, effective
public communication strategy immediately? Is that what you are
doing?
Mr. Grumbles. Well, we do require public communication, and
the rules do contemplate effective public communication. The
smarter the country gets, the more we all learn from these
experiences, is that there are great dividends that can be paid
by getting into greater specificity and providing additional
guidance or workshops bringing in the public to share
experiences on how best--how to make it the most effective
possible.
And so that is going to be a priority. That is an area that
we really want to pursue. I would say, Congressman, on the
schools and daycare facilities issue, that is one where our
goal at EPA is really, unlike it has ever been done before, to
bring together the teachers and the school administrators and
to share experiences and lessons about how best to sample and
monitor and to get everyone informed about safe drinking water
in schools. And that is the type of----
Mr. Green. But is guidance mandatory from EPA to the local
agency? Do you----
Mr. Grumbles. By its very nature, guidance is not
enforceable. It is meant to be supplemental and informative and
helpful to complement the regulations and the statute.
Mr. Gillmor. The gentleman's time has expired.
Mr. Green. Thank you, Mr. Chairman.
Mr. Gillmor. The gentleman from Michigan.
Mr. Stupak. Mr. Chairman, I ask that my opening statement
be made part of the record.
Mr. Gillmor. Without objection, hearing none, so ordered.
Mr. Stupak. Thank you.
Mr. Grumbles, several weeks ago the GAO--Government
Accounting Office--released a report finding that the Defense
Department is failing to sample and clean up contamination from
munitions constituents such as perchlorate at its bases around
the country. Do you believe the Department of Defense policy of
no systematic sampling and no clean up of perchlorate
contamination at DoD facilities is protecting our drinking
water supplies?
Mr. Grumbles. Congressman, I haven't read that specific
report. I am generally familiar with this extremely important
issue about compliance----
Mr. Stupak. Okay.
Mr. Grumbles. [continuing] with the----
Mr. Stupak. But do you believe they should have systematic
sampling?
Mr. Grumbles. I believe that there should be, for all
facilities and responsible parties that may have--may be
polluting, there needs to be an approach to monitor and to
check to see what is being released----
Mr. Stupak. So they should have a policy on sampling and
cleaning up, right?
Mr. Grumbles. Well, I am not sure what the current state of
play is on whether they have a policy. I can tell you----
Mr. Stupak. GAO says they don't have a policy. Do you think
they should have a policy?
Mr. Grumbles. They should continue to work with the EPA and
with their State regulators to have an approach.
Mr. Stupak. No, no, no. The question is: should they a
policy?
Mr. Grumbles. I think there should be a basic--it makes----
Mr. Stupak. Makes sense, doesn't it?
Mr. Grumbles. [continuing] common sense to have some----
Mr. Stupak. Sure.
Mr. Grumbles. [continuing] basic approach to monitoring----
Mr. Stupak. Sure.
Mr. Grumbles. [continuing] emissions. I can't speak to the
details, and I don't know what the----
Mr. Stupak. Okay. I just asked if there should be a policy.
I think you agree with me there should be. So doesn't it make
more sense to have a policy to prevent migration of
contaminants like perchlorate and clean them up before they
spread through a whole aquifer and show up in tap water in
someone's home?
Mr. Grumbles. I think that one of the reasons that
Superfund or other environmental statutes can claim success is
that they take the overall approach of prevention is a lot less
costly and easier to achieve than after-the-fact remediation.
Mr. Stupak. Sure. So DoD should have a policy, then, to
prevent the migration of contaminants before it gets in
someone's home, right?
Mr. Grumbles. I am sure they have a basic approach or
philosophy on preventing----
Mr. Stupak. Well, I don't want an approach or a philosophy.
I want a policy in place that can be enforced. Don't you agree
there should be a policy in place we can enforce to prevent
migration of, like, perchlorate into aquifers and into tap
water?
Mr. Grumbles. I think EPA would expect no less than in
working with its sister agency--DoD--that they have----
Mr. Stupak. Okay. I am glad you work with them, but don't
you think there should be a policy?
Mr. Grumbles. I think there should be a policy. I am not
sure what that entails or what you mean by that.
Mr. Stupak. Okay.
Mr. Grumbles. But I----
Mr. Stupak. Well, policy that would prevent migration of
contaminants, like perchlorate, to get into aquifers and
pollute people's homes, so when they turn on their tap water it
can be safe. That is the same thing we are talking about here
in DC. So there should be a policy like that, should there not?
Mr. Grumbles. I think the current Federal laws would
require no less than to have some--a basic approach to prevent
contamination and spreading.
Mr. Stupak. I don't mean to argue with you, but I don't
want a filibuster from you either. All I am asking for is a
policy. Basic approach is a lot different than a policy, isn't
it? Policy is something you can enforce. DoD doesn't have one,
and at their bases they have 24 million acres that they have
used for testing and firing munitions.
And there is a lot of contamination, and for years we have
been sitting here just trying to get them to clean up places
like Camp Lejeune. And they won't do it, because there is no
policy. Don't you think you should--EPA should enforce the
policy and get these places cleaned up?
Mr. Grumbles. For instance, with groundwater contamination,
I think EPA would vigorously seek to ensure that the Defense
Department complies with requirements under the Safe Drinking
Water Act or other environmental statutes.
Mr. Stupak. So why hasn't the EPA done it? In the seven
places--six of the seven sites that were visited, they have
high levels of perchlorate contamination. None of them were
conducting cleanup actions specifically directed at
perchlorate.
Mr. Grumbles. Congressman, I think that the perchlorate
issue is a very serious one, and groundwater contamination and
all of the health effects associated with it. I think the
Superfund office and other offices at EPA are better equipped
to deal with specific questions that you are raising, but I can
assure you that as we look at the challenges of perchlorate we
are interested in not just pollution prevention and working
with Federal and non-Federal entities but also getting to key--
the key question of health effects, risk assessment, level of
occurrences, and meaningful opportunities----
Mr. Stupak. Well, let me ask you this question.
Mr. Grumbles. [continuing] to reduce the risk.
Mr. Stupak. There are at least 50 Defense Department
facilities with perchlorate contamination in the groundwater or
surface water. Some of the Defense--Department of Defense
facilities, as you mentioned, are on the Superfund list. Others
like the Aberdeen Proving Ground, the perchlorate contamination
migrated offsite and affected drinking water supplies. I
mentioned Camp Lejeune.
We also know that NASA and the Department of Energy are
cleaning up perchlorate contamination of groundwater at
facilities in California. However, DoD is refusing to clean up
its perchlorate contamination of groundwater until the EPA
promulgates a maximum contaminant level for perchlorate. When
does the EPA intend to promulgate the rules of a maximum
contaminant level for perchlorate? When are you going to do
that?
Mr. Grumbles. We are going to--we are committed to getting
all of the information we can as quickly as possible. I don't
have a specific date or timeframe for you. But as you and your
colleagues know, the----
Mr. Stupak. But you have been working on that MCL for a
long time. When are you going to do it?
Mr. Grumbles. Well, first, we need to get some input from
the experts at the National Academy of Sciences on the health
risks, so that can inform us in our decision as to what is the
right number----
Mr. Stupak. Yes. But, see, my concern is it is a lot like
the Canadian trash coming in here. For 13 years, EPA has been
saying they are going to enforce it soon. It is 13 years later.
And when they testified last year they said it would be soon.
And now they came and testified the other day again, and when I
asked the question they said it would be soon.
I really have a problem with ``soon,'' especially when I am
dealing with the EPA, because soon never comes. How about some
definite timelines that we can expect that this proposed rule
on MCL for perchlorate will be----
Mr. Grumbles. We want to make sure we get the science right
and do it as quickly as possible. We are expecting to get the
National Academy of Sciences report in January. After that,
Congressman, in reviewing the occurrence data base that we
have--and what we have to date indicates that perchlorate is in
22 States, I believe, across the country. There are problems
with that, so we have to review that, and then go through the
regulatory review process and make that determination.
That can take, in order for it to be sustainable and to
hold up in court, if it is challenged by industry or by
somebody----
Mr. Stupak. Sure.
Mr. Grumbles. [continuing] it takes some time to do that.
But we--that doesn't mean that things can't be done while we
are going through that very extensive, deliberative Safe
Drinking Water Act process.
Mr. Stupak. Well, how long does it take to be sometime? How
long is sometime?
Mr. Grumbles. Well----
Mr. Stupak. I got soon now, and that is at least 14 years.
So what is sometime?
Mr. Gillmor. Well, I don't know how long it will take to
get your definition here, but the gentleman's time has expired.
Mr. Stupak. I know it has been 14 years; I am still
waiting. Thank you.
Mr. Gillmor. Your time has expired, so----
Mr. Grumbles. Well, I would just offer to the Congressman,
I certainly get the message that you are making. And in terms
of talking about the timeframe and the necessary legal steps
that need to be taken under the Safe Drinking Water Act, I
can't talk to the steps under other statutes or programs. I
would be happy--I would welcome the opportunity to follow up
with you and committee staff on that front.
Mr. Gillmor. Yes. And all the witnesses have agreed to
answer questions in writing. So I am sure that the gentleman
from Michigan will get his answer soon.
That concludes the hearing with this panel. I want to thank
all of you for coming and for your very helpful testimony.
We would like to ask the second panel, which is John
Stephenson of the General Accountability Office----
Mr. Johnson. Mr. Chairman, I would----
Mr. Gillmor. Yes, Mr. Johnson.
Mr. Johnson. [continuing] seek consent of the committee to
allow me to amend my testimony to include--my written testimony
to include the blood lead level test results that have been
done in the District of Columbia, if there is no objection.
Mr. Gillmor. Without objection, that will be entered in the
record as part of your testimony.
Mr. Johnson. Thank you.
Mr. Gillmor. If you are ready, Mr. Stephenson will begin,
and we are very pleased to have with us on this panel John
Stephenson, who is the Director of Natural Resources and
Environment Team for the General Accountability Office.
Mr. Stephenson?
STATEMENT OF JOHN B. STEPHENSON, DIRECTOR, NATURAL RESOURCES
AND ENVIRONMENT TEAM, UNITED STATES GENERAL ACCOUNTABILITY
OFFICE
Mr. Stephenson. Thank you, Mr. Chairman, and members of the
committee. At the request of this subcommittee, as you know, we
are about 2 months or so into examining issues concerning lead
in drinking water in general, and the situation in Washington,
DC in particular. My testimony today contains our preliminary
observations on these issues, and highlights areas for further
examination.
Although rarely the sole cause of lead poisoning, lead in
drinking water can significantly increase a person's total lead
exposure. EPA estimates that drinking water is the source of
about 20 percent of Americans' lead exposure, but that it may
be as high as 60 percent for infants who drink baby formulas or
concentrated juices that are mixed with water.
The delivery of safe drinking water to residents requires
that water systems and regulators work cooperatively in
fulfilling the requirements of the Safe Drinking Water Act.
Lead in drinking water is regulated under the Act's 1991 lead
and copper rule. The rule requires water systems to treat their
water to limit its corrosiveness, monitor tap water supplies
for evidence of elevated lead levels, which is 15 parts per
billion as you have heard, and report this information.
If over 10 percent of the samples exceed this level, as was
the case in the District, specific actions are required such as
public notification and education, increased sampling, and lead
line replacement.
In March, you asked that we, one, examine the current
structure and level of coordination among key government
entities in the District of Columbia; second, that we determine
how public notification and outreach have been conducted in the
District as compared to other systems facing similar
circumstances; three, assess what is being done to identify and
track at-risk populations; four, evaluate the state of research
on lead exposure and how this might help inform other drinking
water utilities of potential problems in their systems.
In summary, here is what we have found so far. As to
coordination, it is clear that the responsible entities,
particularly EPA and the District's Water and Sewer Authority--
WASA--could have better coordinated and communicated timely and
accurate information in the years preceding the current
controversy.
In fact, it is noteworthy that WASA and EPA, as you just
heard, have recently agreed to take steps to improve
coordination. WASA, for example, will improve tap water
sampling and reporting procedures, and EPA will change the way
in which it handles compliance data from WASA and oversees its
public notification efforts.
Our future work will also examine the interrelationships
among the other key agencies, such as the Washington Aqueduct
and the District's Department of Health. As to public
notification, EPA acknowledges that its efforts to oversee
WASA's notification procedures could have been better. Other
water systems facing elevated lead levels used public
notification and education practices that were much more
comprehensive than WASA's.
For example, you have already mentioned the Massachusetts
Water Authority in Boston, the Portland Water Bureau. Their
public notification efforts included, for example, tailoring
their communications to varied audiences in their service
areas, testing the effectiveness of their communication
materials, and linking demographic and infrastructure data to
identify populations at greatest risk from lead in drinking
water.
As to the tracking of at-risk populations, WASA and the
Health Department face challenges in collecting the information
needed to identify District citizens at greatest risk from lead
in drinking water. There is partial information on which
customers have lead service pipes--as you hear Mr. Johnson,
about 23,000 lines--and more information is being collected on
over 27,000 more lines of unknown material.
However, efforts to better link data on at-risk populations
with data on customers with lead service pipes is just
beginning.
Finally, as to lead exposure research, while much is known
about the hazards of lead in the human body and about how lead
from paint, soil, and dust enter the body, little research has
been done to determine actual lead exposure from drinking
water. And the information that does exist is dated.
Our future work will examine the plans of EPA and other
organizations, research institutions, to fulfill this key
information gap. We plan to issue a more comprehensive report
to the subcommittee on these and other issues later this year,
Mr. Chairman.
That concludes the summary of my statement, and I will
answer questions as well now.
[The prepared statement of John Stephenson follows:]
Prepared Statement of John B. Stephenson, Director, Natural Resources
and Environment, U.S. Government Accountability Office
Mr. Chairman and Members of the Subcommittee: Thank you for the
opportunity to discuss our work to date on the issues surrounding
elevated levels of lead in Washington, D.C. drinking water. At the
request of this Subcommittee, we are examining issues concerning lead
in drinking water generally and the situation in Washington, D.C., in
particular. Our testimony today lays out our preliminary observations
on these issues and highlights areas of further examination.
Although rarely the sole cause of lead poisoning, lead in drinking
water can significantly increase a person's total lead exposure. EPA
estimates that drinking water is the source of about 20 percent of
Americans' lead exposure, but that it may be as high as 60 percent for
infants who drink baby formulas and concentrated juices that are mixed
with water. Adults who drink water with high lead concentrations could
develop kidney problems or high blood pressure. Developing fetuses,
infants and young children are more vulnerable to lead from all
sources, including drinking water. Their exposure to lead may delay
their physical or mental development.
The delivery of safe water to residents requires that water systems
and regulators work cooperatively in fulfilling the requirements of the
Safe Drinking Water Act.1 In most cases, states have primary
oversight and enforcement authority under the Act. Lead in drinking
water is regulated under the Act's 1991 Lead and Copper
Rule.2 The rule requires water systems to treat their water
to limit its corrosiveness, monitor tap water samples for evidence of
elevated levels of lead, and report this information to their state. In
addition, drinking water systems may consult with state health agencies
when communicating with their customers about health risks from
drinking water.
---------------------------------------------------------------------------
\1\ 42 U.S.C. 300f-300j.
\2\ 40 C.F.R. pt. 141, subpart I. The Lead and Copper Rule
established an action level of 15 parts per billion (ppb) for lead in
drinking water. Under the rule, the action level is exceeded if lead
levels are higher than 15 ppb in over 10 percent of tap water samples
taken. For each monitoring period, a system must report the lead level
at the 90th percentile of homes monitored. For example, if a system
monitors 100 homes, it sorts its results from the lowest to the highest
concentrations and reports the concentration it observed in the 90th
sample.
---------------------------------------------------------------------------
The relationship between regulators and water systems is more
complicated in the District of Columbia, where the Washington Aqueduct,
owned by the U.S. Army Corps of Engineers, draws and treats water from
the Potomac River. The Aqueduct sells the treated water to the District
of Columbia Water and Sewer Authority (WASA), which distributes it to
District residents. The Environmental Protection Agency's (EPA)
Region--III Office in Philadelphia, Pennsylvania, has primary oversight
and enforcement authority for the District's public water systems. The
District of Columbia's Department of Health, while having no formal
role under the Safe Drinking Water Act, is responsible for educating
District residents on potential health risks.
In the District, the Washington Aqueduct treats drinking water and
monitors for most contaminants, while WASA monitors tap water samples
for lead and reports these results to EPA's Philadelphia Office. Tap
water monitoring is important because, unlike most drinking water
contaminants, lead is not generally introduced to drinking water
supplies from source water. Rather, lead leaches into drinking water as
it travels through lead service pipes, over pipe joints connected with
lead-based solder, and through brass plumbing fixtures that contain
lead. According to EPA, its Philadelphia Office is responsible for
providing technical assistance to the Aqueduct and WASA on how to
comply with federal regulations; ensuring that they report the
monitoring results to EPA by required deadlines; taking enforcement
actions if violations occur; and using those enforcement actions to
return the water systems to compliance in a timely fashion.
Significant concerns were raised in early 2004 about how federal
and local agencies were carrying out their responsibilities under the
Safe Drinking Water Act. At that time, the local media reported that a
number of tap water samples showed elevated levels of lead.
You asked that we (1) examine the current structure and level of
coordination among key government entities that implement the Safe
Drinking Water Act's regulations for lead in the District of Columbia,
and identify any improvements to increase efficiency and
accountability, (2) determine how other drinking water systems that
exceeded the EPA action level for lead have conducted public
notification and outreach, (3) assess the availability of data
necessary to determine which adult and child populations are at
greatest risk of exposure to elevated lead levels, and what information
WASA is gathering to help track their health, (4) evaluate the state of
research on lead exposure, and how this information could help inform
other drinking water utilities of potential problems in their systems.
To respond to these questions, we are interviewing key officials
and staff with the federal and local agencies responsible for managing
drinking water and monitoring health for lead exposure in Washington,
D.C., including officials at EPA's headquarters and in its Philadelphia
Office, WASA, the Washington Aqueduct, and the D.C. Department of
Health. We are also (1) reviewing records documenting key activities
and interactions among these agencies, and examining their current
responses to the lead problem, (2) contacting academic and non-
governmental experts in lead contamination, and (3) examining how other
water systems facing similar circumstances notified and educated their
customers on lead health risks, and how they interacted with federal,
state, and local agencies to respond to the problem. Many of the facts
and circumstances surrounding the District's lead controversy are the
subject of active litigation. Accordingly, we do not take a position on
these issues and on how they bear on the question of interagency
coordination and communication, and instead report them only as stated
by the affected parties.
We are here to present our preliminary observations on these
issues. We will report our final findings and any recommendations we
may develop at a later date. In summary:
Providing safe drinking water requires that water systems,
regulators, and public health agencies fulfill individual roles, yet
work together in a coordinated fashion. It is particularly important
that these entities report and communicate information to each other in
a timely and accurate manner. Recent public statements and corrective
actions by the responsible entities, particularly EPA and WASA, clearly
indicate that coordination could have been better in the years
preceding the current controversy. As our work continues, we will seek
to examine (to the extent appropriate) specific ways in which improved
coordination between EPA and WASA could help both agencies better
fulfill their responsibilities. We will also examine interrelationships
among other key agencies (such as the Aqueduct and the D.C. Department
of Health); how other water systems in similar situations interacted
with federal, state, and local agencies; and what the experiences of
these other jurisdictions may suggest concerning how improved
coordination can better protect drinking water in the District of
Columbia.
Other water systems facing elevated lead levels used public
notification and education practices that appear to offer lessons for
conducting outreach to water customers, including those in the District
of Columbia. For example, some of the practices of the two systems we
have begun to examine--the Massachusetts Water Resources Authority and
the Portland Water Bureau--include tailoring their communications to
varied audiences in their service areas, testing the effectiveness of
their communication materials, and linking demographic and
infrastructure data to identify populations at greatest risk from lead
in drinking water.
WASA faces challenges in collecting the information needed to
identify District citizens at greatest risk from lead in drinking
water. Specifically, it has partial information on which of its
customers have lead service pipes, although it is currently in the
process of obtaining more complete information. In our future work, we
will examine the efforts of other water systems to go one step further
by linking data on at-risk populations (such as pregnant mothers,
infants, and small children) with data on homes suspected of being
served by lead service pipes and other plumbing fixtures that may leach
lead into drinking water.
Much is known about the hazards of lead in the human body and
about how lead from paint, soil, and dust enter the body. However,
little research has been done to determine actual lead exposure from
drinking water, and the information that does exist is dated. In our
future work, we will examine the plans of EPA and other organizations
to fill this key information gap.
BACKGROUND
Lead is unusual among drinking water contaminants in that it seldom
occurs naturally in source water supplies like rivers and lakes.
Rather, lead enters drinking water primarily as a result of the
corrosion of materials containing lead in the water distribution system
and in household plumbing. These materials include lead service pipes
that connect a house to the water main, household lead-based solder
used to join copper pipe, and brass plumbing fixtures such as faucets.
The Safe Drinking Water Act is the key federal law protecting
public water supplies from harmful contaminants. The Act established a
federal-state arrangement in which states may be delegated primary
implementation and enforcement authority (``primacy'') for the drinking
water program. Except for Wyoming and the District of Columbia, all
states and territories have received primacy. For contaminants that are
known or anticipated to occur in public water systems and that the EPA
Administrator determines may have an adverse impact on health, the Act
requires EPA to set a non-enforceable maximum contaminant level goal
(MCLG) at which no known or anticipated adverse health effects occur
and that allows an adequate margin of safety. Once the MCLG is
established, EPA sets an enforceable standard for water as it leaves
the treatment plant, the maximum contaminant level (MCL). The MCL
generally must be set as close to the MCLG as is ``feasible'' using the
best technology or other means available, taking costs into
consideration.
The fact that lead contamination occurs after water leaves the
treatment plant has complicated efforts to regulate it in the same way
as most contaminants. In 1975, EPA set an interim MCL for lead at 50
parts per billion (ppb), but did not require sampling of tap water to
show compliance with the standard. Rather, the standard had to be met
at the water system before the water was distributed. The 1986
amendments to the Act directed EPA to issue a new lead regulation, and
in 1991, EPA adopted the Lead and Copper Rule.
Instead of an MCL, the rule established an ``action level'' of 15
ppb for lead in drinking water, and required that water systems take
steps to limit the corrosiveness of their water. Under the rule, the
action level is exceeded if lead levels are higher than 15--ppb in over
10 percent of tap water samples taken. Large systems, including WASA,
generally must take at least 100 tap water samples in a 6-month
monitoring period. Large systems that do not exceed the action level or
that maintain optimal corrosion control for two consecutive 6-month
periods may reduce the number of sampling sites to 50 sites and reduce
collection frequency to once per year. If a water system exceeds the
action level, other regulatory requirements are triggered. The water
system must intensify tap water sampling, take additional actions to
control corrosion, and educate the public about steps they should take
to protect themselves from lead exposure. If the problem is not abated,
the water system must annually replace 7 percent of the lead service
lines under its ownership.
The public notification requirements of the Safe Drinking Water Act
are intended to protect public health, build trust with consumers
through open and honest sharing of information, and establish an
ongoing, positive relationship with the community.3 While
public notification provisions were included in the original Act,
concerns have been raised for many years about the way public water
systems notify the public regarding health threats posed by
contaminated drinking water. In 1992, for example, we reported, among
other things, that (1) there were high rates of noncompliance among
water systems with the public notification regulations in effect at
that time and (2) notices often did not clearly convey the appropriate
information to the public concerning the health risks associated with a
violation and the preventive action to be taken.4 The 1996
Amendments to the Safe Drinking Water Act attempted to address many of
these concerns by requiring that consumers of public water supplies be
given more accurate and timely information about violations and that
this information be in a form that is more understandable and useful.

Drinking water is provided to District of Columbia residents under
a unique organizational structure:
The U.S. Army Corps of Engineers' Washington Aqueduct draws water
from the Potomac River and filters and chemically treats it to meet EPA
specifications. The Aqueduct produces drinking water for approximately
1 million citizens living, working, or visiting in the District of
Columbia, Arlington County, Virginia, and the City of Falls Church,
Virginia. Managed by the Corps of Engineers' Baltimore District, the
Aqueduct is a federally owned and operated public water supply agency
that produces an average of 180 million gallons of water per day at two
treatment plants located in the District. All funding for operations,
maintenance, and capital improvements comes from revenue generated by
selling drinking water to the District of Columbia, Arlington County,
Virginia, and the City of Falls Church, Virginia.
The District of Columbia Water and Sewer Authority buys its
drinking water from the Aqueduct. WASA distributes drinking water
through 1,300 miles of water mains under the streets of the District to
individual homes and buildings, as well as to several federal
facilities directly across the Potomac River in Virginia. From its
inception in 1938 until 1996, WASA's predecessor, the District of
Columbia Water and Sewer Utility Administration, was a part of the
District's government. In 1996, WASA was established by District of
Columbia law as a semiautonomous regional entity. WASA develops its own
budget, which is incorporated into the District's budget and then
forwarded to Congress. All funding for operations, improvements, and
debt financing come from usage fees, EPA grants, and the sale of
revenue bonds.
EPA's Philadelphia Regional Office has primary oversight and
enforcement responsibility for public water systems in the District.
According to EPA, the Regional Office's oversight and enforcement
responsibilities include providing technical assistance to the water
suppliers on how to comply with federal regulations; ensuring that the
suppliers report the monitoring results to EPA by the required
deadlines; taking enforcement actions if violations occur; and using
those enforcement actions to return the system to compliance in a
timely fashion.
The District's Department of Health, while having no formal role
under the Act, is responsible for identifying health risks and
educating the public on those risks.
COORDINATION AMONG AGENCIES IS CRITICAL TO ENSURE SAFE DRINKING WATER
Providing safe drinking water requires that water systems,
regulators, and public health agencies fulfill individual
responsibilities yet work together in a coordinated fashion. It is
particularly important that these entities report and communicate
information to each other in a timely and accurate manner. In the case
of drinking water in the District of Columbia, one of the key
relationships is the one between WASA, the deliverer of water to
District customers, and EPA's Philadelphia Office, the regulator
charged with overseeing WASA's compliance with drinking water
regulations. Of particular note, one of WASA's key obligations is to
monitor the water it supplies to District customers through a tap water
sampling program, and to report these results accurately and in a
timely manner to EPA's Philadelphia Office. As EPA itself has noted,
one of the Philadelphia Office's key obligations is to ensure that WASA
understands the reporting requirements and reports monitoring results
by required deadlines.
It is noteworthy that WASA and EPA have taken or agreed to take
steps that are clearly intended to improve communication and
coordination between the agencies. For example:
Under the Consent Order signed by EPA and WASA on June 17, 2004,
WASA agreed to improve its format for reporting tap water samples by
ensuring that the reports include tap water sample identification
numbers, sample date and location, lead and copper concentration,
service line materials, and reasons for any deviation from previously
sampled locations. The monitoring reports are also to include the
laboratory data sheets, which contain the raw test data recorded
directly by the laboratory. Under the Order, WASA also agreed to submit
to EPA for comment a plan and schedule for enhanced information,
database management, and reporting. The plan is to describe how
monitoring reports will be generated, maintained, and submitted to EPA
in a timely fashion.
EPA's Philadelphia Office has altered the way in which it will
handle compliance data from WASA and the Washington Aqueduct. According
to the office, compliance data from both water systems will now be sent
to those in the Office responsible for enforcing the Safe Drinking
Water Act, so as to separate the enforcement/compliance assurance
function from the municipal assistance function.
Aside from the tap water monitoring issue, EPA's Philadelphia
Office acknowledges that its oversight of WASA public notification and
education efforts could have been better, noting that ``In hindsight,
EPA should have asked more questions about the extent, coverage and
impact of DC WASA's public education program, and reacted to fill the
public education gaps where they were evident.'' 5 To
address the problem, the Philadelphia Office reported on its website
that it will have to make some improvements in the way it exercises its
own oversight responsibilities.6 Suggested improvements
include obtaining written agreement from WASA to receive drafts of
education materials and a timeline for their submission, reviewing
drafts of public education materials for compliance with requirements,
as well as effectiveness of materials and delivery, and acquiring
outside expertise to assist in evaluating outreach efforts.

As our work continues, we will seek to examine (to the extent it
does not conflict with active litigation) other ways in which improved
coordination between WASA and EPA could help both agencies better
fulfill their responsibilities. We will also examine interrelationships
that include other key agencies, such as the Aqueduct and the D.C.
Department of Health. We will also examine how other water systems in
similar situations interacted with federal, state, and local agencies.
These experiences may offer suggestions on how coordination can be
improved among the agencies responsible for protecting drinking water
in the District of Columbia.
EXPERIENCES OF OTHER WATER SYSTEMS HIGHLIGHT EFFECTIVE WAYS TO INFORM
AND EDUCATE THE PUBLIC
WASA is not the first system to exceed the action level for lead.
According to EPA, when the first round of monitoring results was
completed for large water systems in 1991 pursuant to the Lead and
Copper Rule, 130 of the 660 systems serving populations over 50,000
exceeded the action level for lead. EPA data show that since the
monitoring period ending in 2000, 27 such systems have exceeded the
action level.7 As part of our work, we will be examining the
innovative approaches some of these systems have used to notify and
educate their customers. I would like to touch on the activities of two
such systems, the Massachusetts Water Resources Authority and the
Portland, Oregon, Water Bureau. Each of these systems has employed
effective notification practices in recent years that may provide
insights into how WASA, and other water systems, could improve their
own practices.

public water systems (Updated as of June 1, 2004).
---------------------------------------------------------------------------
Massachusetts Water Resources Authority
The Massachusetts Water Resources Authority (MWRA) is the wholesale
water provider for approximately 2.3 million customers, mostly in the
metropolitan Boston area. Under an agreement with the Massachusetts
Department of Environmental Protection, monitoring for lead under the
Lead and Copper Rule occurs in each of the communities that MWRA serves
and the results are submitted together. Initial system-wide tap water
monitoring results in 1992 showed a 90th percentile lead concentration
of 71 ppb (meaning 10 percent of its samples scored at this level and
above). According to MWRA, adjustments in corrosion control have led to
a reduction in lead levels, but the 90th percentile lead concentration
in MWRA's service area has still been above the action level in four of
the seven sampling events since early 2000.
According to an MWRA official, the public education program for
lead in drinking water is designed to ensure that all potentially
affected parties within MWRA's service area receive information about
lead in drinking water. He noted, for example, that while the Lead and
Copper Rule requires that information be sent to consumers in their
water bills, the large population of renters living in MWRA's service
area often do not receive water bills. Therefore, MWRA included
information about lead in its consumer confidence report, which is sent
to all mailing addresses within the service area. Additionally, MWRA
uses public service announcements, interviews on radio and television
talk shows, appearances at city councils and other local government
agency meetings, and articles in local newspapers to convey
information. MWRA also conducted focus groups to judge the
effectiveness of the public education program and continually makes
changes to refine the information about lead in drinking water.
An MWRA official also noted that MWRA focuses portions of its lead
public education program on the populations most vulnerable to the
health effects of lead exposure. For example, MWRA worked with
officials from the Massachusetts Women, Infants and Children
Supplemental Nutrition Program (WIC) to design a brochure to help
parents understand how to protect their children from lead in drinking
water. Among other things, the brochure includes the pertinent
information in several foreign languages, including Spanish,
Portuguese, and Vietnamese. The WIC program also includes information
on how to avoid lead hazards when preparing formula.
Portland Water Bureau
The Portland Water Bureau provides drinking water to approximately
787,000 people in the Portland metropolitan area, nearly one-fourth of
the population of Oregon. Since 1997, the city has exceeded the lead
action level 6 times in 14 rounds of monitoring. According to Bureau
officials, the problem stems mainly from lead solder used to join
copper plumbing and from lead in home faucets. Portland's system has
never had lead service lines, and the Water Bureau finished removing
all lead fittings within the water system's control in 1998.
The Portland Water Bureau sought flexibility in complying with the
Lead and Copper Rule. The state of Oregon allowed the Water Bureau to
implement a lead hazard reduction program as a substitute for the
optimal corrosion control treatment requirement of the Lead and Copper
Rule. Portland's lead hazard reduction program is a partnership between
the Portland Water Bureau, the Multnomah County and Oregon State health
departments, and community groups. According to Portland Water Bureau
officials, the program consists of four components: (1) water treatment
for corrosion control; (2) free water testing to identify customers who
may be at significant risk from elevated lead levels in drinking water;
(3) a home lead hazard reduction program to prevent children from being
exposed to lead from lead-based paint, dust, and other sources; and (4)
education on how to prevent lead exposure targeted to those at greatest
risk from exposure.
As the components suggest, the program is focused on reducing
exposure to lead through all exposure pathways, not just through
drinking water. For example, the Water Bureau provides funding to the
Multnomah County Health Department's LeadLine--a phone hotline that
residents can call to get information about all types of lead hazards.
Callers can get information about how to flush their plumbing to reduce
their lead exposure and can request a lead sampling kit to determine
the lead concentration in the drinking water in their home. The Water
Bureau also provides funding for lead education materials provided to
new parents in hospitals, for billboards and movie advertisements
targeted to neighborhoods with older housing stock, and to the
Community Alliance of Tenants to educate renters on potential lead
hazards. Each of these materials directs people to call the LeadLine if
they need additional information about any lead hazard. The Water
Bureau evaluates the results of the program by tracking the number of
calls to the LeadLine, and by surveying program participants to
determine their satisfaction with the program and the extent to which
the program changed their behavior.
In January 2004, the Portland Water Bureau sent a targeted mailing
to those residents most likely to be affected by lead in drinking
water. The mailing targeted homes of an age most likely to contain
lead-leaching solder where a child 6 years old or younger lived.
Approximately 2,600 postcards were sent that encouraged residents to
get their water tested for lead, learn about childhood blood lead
screening, and reduce lead hazards in their homes. Water Bureau
officials said that they obtained the information needed to target the
mailing from a commercial marketing company, and that the commercial
information was inexpensive and easy to obtain.
WASA FACES CHALLENGES IN IDENTIFYING AT-RISK POPULATIONS
In an ideal world, a water utility such as WASA would have several
different types of information that would allow it to monitor the
health of individuals most susceptible to the health effects of lead in
drinking water. The utility would know the location of all lead service
lines and homes with leaded plumbing (pipes, solder and/or fixtures)
within its service area. The utility would also know the demographics
of the residents of each of these homes. With this information, the
utility could identify each pregnant woman or child six years old or
younger who would be most likely to be exposed to lead through drinking
water. These individuals could then be educated about how to avoid lead
exposure, and lead exposure for each of these individuals could then be
monitored through water testing and blood lead testing.
Unfortunately, WASA and other drinking water utilities do not
operate in an ideal world. WASA does have some information on the
location of lead service lines within its distribution area. Its
predecessor developed an inventory of lead service lines in its
distribution system in 1990 as part of an effort to identify sampling
locations to comply with the Lead and Copper Rule. According to WASA
officials, identifying the locations of lead service lines was
difficult because many of the records were nearly 100 years old and
some of the information was incomplete. According to this 1990
inventory, there were approximately 22,000 lead service lines. WASA
updated the inventory in September 2003, and estimated that it had
23,071 ``known or suspected'' lead service lines. WASA subsequently
identified an additional 27,495 service lines in the distribution
system made of ``unknown'' materials. Consequently, there is some
uncertainty over the actual number and location of the lead service
lines in WASA's distribution system. The administrative order that EPA
issued in June 2004 requires WASA to further update its inventory of
lead service lines.
Regardless of the information WASA has about the location of lead
service lines, according to WASA officials, WASA has little information
about the location of customers who are particularly vulnerable to the
effects of lead. The District's Department of Health is responsible for
monitoring blood lead levels for children in the District. Officials
from the Department of Health told us that they maintain a database of
the results of all childhood blood lead testing in the District, and
have studied the distribution of blood lead levels in children on a
neighborhood basis. However, according to a joint study by the D.C.
Department of Health and the Centers for Disease Control and Prevention
(CDC) published in March 2004, it is difficult to discern any effect of
lead in drinking water on children's blood lead levels because the
older homes most likely to have lead service lines are also those most
likely to have other lead hazards, such as lead in paint and dust. This
joint study also described efforts by the Department of Health and the
United States Public Health Service to conduct blood lead monitoring
for residents of homes whose drinking water test indicated a lead
concentration greater than 300--ppb. None of the 201 residents tested
were found to have blood lead levels exceeding the levels of concern
for adults or children, as appropriate.
Researchers Face Gaps in Knowledge Regarding the Risks Posed by Lead in
Drinking Water
A good deal of research has been conducted on the health effects of
lead, in particular on the effects associated with certain pathways of
contamination, such as ingestion of leaded paint and inhalation of
leaded dust. In contrast, the most relevant studies on the isolated
health effects of lead in drinking water date back nearly 20 years--
including the Glasgow Duplicate Diet Study on lead levels in children
upon which the Lead and Copper Rule is partially based.8
According to recent medical literature and the public health experts we
contacted, the key uncertainties requiring clarification include the
incremental effects of lead-contaminated drinking water on people whose
blood lead levels are already elevated from other sources of lead
contamination and the potential health effects of exposure to low
levels of lead. As we continue our work, we will examine the plans of
EPA and other organizations to fill these and other key information
gaps.

Lead is a naturally occurring element that, according to numerous
studies, can be harmful to humans when ingested or inhaled,
particularly to pregnant and nursing women and children aged six or
younger. In children, for example, lead poisoning has been documented
as causing brain damage, mental retardation, behavioral problems,
anemia, liver and kidney damage, hearing loss, hyperactivity, and other
physical and mental problems. Exposure to lead may also be associated
with diminished school performance, reduced scores on standardized IQ
tests, schizophrenia, and delayed puberty.
Long-term exposure may also have serious effects on adults. Lead
ingestion accumulates in bones, where it may remain for decades.
However, stored lead can be mobilized during pregnancy and passed to
the fetus. Other health effects in adults that may be associated with
lead exposure include irritability, poor muscle coordination and nerve
damage, increased blood pressure, impaired hearing and vision, and
reproductive problems.
There are many sources of lead exposure besides drinking water,
including the ingestion of soil, paint chips and dust; inhalation of
lead particles in soil or dust in air; and ingestion of foods that
contain lead from soil or water. Extensive literature is available on
the health impacts of lead exposure, particularly from contaminated air
and dust. CDC identified in a December 2002 Morbidity and Mortality
Weekly Report the sources of lead exposure for adults and their
potential health effects.9 In a September 2003 Morbidity and
Mortality Weekly Report, CDC identified the most prevalent sources of
lead in the environment for children, and correlated high blood lead
levels in children with race, sex, and income bracket.10 The
surveys suggest that Hispanic and African-American children are at
highest risk for lead poisoning, as well as those individuals who are
recipients of Medicaid. Dust and soil contaminated by leaded paint were
documented as the major sources of lead exposure. Children and adults
living in housing built before 1950 are more likely to be exposed to
lead paint and dust and may therefore have higher blood lead levels.

Articles in numerous journals have reported on the physical and
neurological health effects on children of lead in paint, soil, and

2003 that associated environmental lead exposure with decreased growth
and delayed puberty in girls.11 In 2000, the Journal of
Public Health Medicine examined the implications of lead-contaminated
soil, its effect on produce, and its potential health effects on
consumers.12 Lead can also enter children's homes if other
residents are employed in lead contaminated workplaces. In 2000,
Occupational Medicine found that children of individuals exposed to
lead in the workplace were at higher risk for elevated blood lead
levels.13 The EPA has aided in some similar research through
the use of its Integrated Exposure Uptake Biokinetic Model for Lead in
Children (IEUBK). This model predicts blood lead concentrations for
children exposed to different types of lead sources.14

According to a number of public health experts, drinking water
contributes a relatively minor amount to overall lead exposure in
comparison to other sources. However, while lead in drinking water is
rarely thought to be the sole cause of lead poisoning, it can
significantly increase a person's total lead exposure--particularly for
infants who drink baby formulas or concentrated juices that are mixed
with water from homes with lead service lines or plumbing systems. For
children with high levels of lead exposure from paint, soil, and dust,
drinking water is thought to contribute a much lower proportion of
total exposure. For residents of dwellings with lead solder or lead
service lines, however, drinking water could be the primary source of
exposure. As exposure declines from sources of lead other than drinking
water, such as gasoline and soldered food cans, drinking water will
account for a larger proportion of total intake. Thus, according to
EPA, the total drinking water contribution to overall lead levels may
range from as little as 5 percent to more than 50 percent of a child's
total lead exposure.15

Mr. Chairman, this completes my prepared statement. I would be
happy to respond to any questions you or other Members of this
Subcommittee may have at this time.
Mr. Gillmor. Thank you very much, Mr. Stephenson, and also
thank you for your work. We talked about the Massachusetts
Water Resources Authority and the Portland Water Bureau and DC
WASA. How could these three systems have had such different
levels of response when all were seeking to comply with
notification requirements of the lead and copper rule? Where do
you see any gaps in the regulation as it is currently drafted?
Mr. Stephenson. The EPA guidance to water authorities has
prescribed language for use in public notification. And it was
used in WASA's case, but essentially the minimum requirements
were met. There are much more opportunities to, as those other
facilities did, test the effectiveness of your public
communication and go the extra mile to make sure the public is
getting the message.
Mr. Gillmor. So basically what you are saying is WASA just
didn't follow through in the way that the others did?
Mr. Stephenson. Yes, both WASA and EPA, in its oversight of
the public notification, also could have improved.
Mr. Gillmor. You state WASA faces challenges in collecting
information needed to identify District citizens at greatest
risk from lead in the drinking water. In your initial
assessment, did you see the potential infrastructure in place
for WASA to link data on at-risk populations? Were they
suspected of being serviced by lead service pipelines?
Mr. Stephenson. Not yet. We are going to cover that issue
in our continuing research for the subcommittee. It is
difficult to do. Portland, for example, actually used marketing
data to determine who lived in the various houses, and then
matched that with the houses that had lead service lines and
were able to do a very good job of cross-walking the data
between those two. We are not there yet in the District.
Mr. Gillmor. In your opinion, what was the fundamental
breakdown in the coordination of activities between WASA,
Washington Aqueduct, and EPA, Region III, that led to a very
delayed response and also the improper notification of lead
levels in the District?
Mr. Stephenson. That is very hard to say. The courts are
probably going to decide some on this issue as well. But EPA is
in a unique oversight role here. In most cases, the States have
primacy for oversight, so the States oversee the drinking water
facilities. So this oversight role for EPA over a drinking
water facility is atypical and unique to the District of
Columbia.
But we think, in addition to just pure oversight and how
good the sampling is, there needs to be sort of a collaborative
relationship between the water provider and the overseer as
well, and we didn't see that communication in this case.
Mr. Gillmor. That was lacking here, yes. A number of
witnesses on our next panel will testify about infrastructure
needs and about increases in Federal funding. I think that
critical to those needs is a better assessment of utilities
asset management plans. Has GAO looked into funding incentive
options and proposals for better asset management?
Mr. Stephenson. Not the incentive options yet. We do have
an outstanding request that we haven't begun working on yet on
alternative funding and financing opportunities. We did do a
piece, as Mr. Grumbles mentioned, on asset management, which
showed how facilities could better manage themselves and more
constructively do capital replacement of their infrastructure
and collect some of the funding that they needed in the rate
structure itself. And we have also done work on the safe
drinking water revolving fund.
Mr. Gillmor. Okay. Thank you very much.
The gentlelady from California.
Ms. Solis. Thank you, Mr. Chairman.
Thank you, also, Mr. Stephenson, for coming here today and
assisting us with trying to decipher how we go about attempting
to address this very important issue. And my question to you
is--back in fiscal year 2000, President Clinton requested $825
million for the drinking water revolving loan fund. Am I
correct that in constant dollars, 2003 dollars, that the
equivalent is actually about $873 million?
Mr. Stephenson. If you adjust it to today's dollars, that
is about right, yes.
Ms. Solis. And am I correct that President Bush's $850
million budget request for fiscal year 2005 would only be worth
$830.7 million in constant dollars for 2003?
Mr. Stephenson. Yes, I believe that is right.
Ms. Solis. Okay. One of the concerns that we are hearing I
think today is that, while we are able to possibly go up to a
million dollars through the fund----
Mr. Stephenson. A billion.
Ms. Solis. The President has not requested that. And, in
fact, for the next several years, if you take this out to 2018
at that same level, he is going to flatline and just propose
that, that we are really going to be pushing back the value of
funding that should be made available to really try to address
this $100 billion gap that currently exists right now. Is that
correct?
Mr. Stephenson. That is true. It is a revolving fund that
does build in total size and is paid back, portions of it are.
There are certain allowances within the Act, that, for example,
can give disadvantages community--a grant as opposed to a loan.
Up to 30 percent of the money can be used for that, so there is
a lot of depletions to the fund. It is not all paid back. But
the fund does slowly build in size.
Ms. Solis. We heard from the witness representing the DC
water area, and my understanding is that they would potentially
need about $300 million alone, just to begin to provide new
piping.
Mr. Stephenson. Yes. Short of recovering all of that in the
rate structure, the revolving fund is the only option.
Ms. Solis. Right. And at that rate, we would be depleting,
obviously, these resources even quicker----
Mr. Stephenson. Theirs and others, yes.
Ms. Solis. [continuing] the sooner we find out where there
may be other hotspots in the country.
One of the things that I was really deeply concerned about
is the use of the fund and how it could help provide for not
just grants but further education programs that might be useful
to residents who obviously may not know that they are currently
in one of these areas, whether it be a school district or a
home or even a place of employment, and what kinds of things
could be offered through this process.
Mr. Stephenson. There are specific percentages of amounts
that can be spent for exactly that purpose for education and
outreach, and a small portion for administration of the
revolving fund.
Ms. Solis. What percentage is that?
Mr. Stephenson. I will have to get it for you for the
record. I think it is fairly high, but I am not sure, like 15
percent.
Ms. Solis. Fifteen percent. And my question would be, then,
because we have such diversity in some of our communities, and
even here in Washington, DC, sometimes you need to tailor the
message to the individual communities and neighborhoods. There
is a recent large influx of Spanish speakers, for example, and
would monies be made available to provide materials in
different languages?
Mr. Stephenson. That is something that is permissible. The
States get an allocation based on set formulas, and then the
States dole that out to the individual communities and the
facilities. But it is permissible that if the State approves
it, they could use the money for those purposes.
Ms. Solis. Okay. One of the concerns I have also is that in
the case here in Washington, DC, many consumers had to actually
bear the burden of paying a little bit--not a little bit,
perhaps a lot more money. The ratepayers are clearly affected
in this circumstance. Is there a way that the revolving fund
could also be utilized to provide some remedy for areas that
are affected that dramatically? Especially with respect to,
say, low income or underserved areas.
I am thinking more that we have a similar program that
exists right now for one of our utilities, the Liheap Program.
If there might be a potential of looking at maybe some creative
ideas to deal with this potential problem as it starts to
possibly surface in other parts of the country.
Mr. Stephenson. The uses for the fund are fairly well
specified in the Act. However, there are additional water funds
and grants that can be used for those purposes.
Ms. Solis. One of the things that I am also concerned about
is the fact that many of our water purveyors eat a lot of these
costs themselves. And some do it for the right reasons,
obviously, and we commend them. What are your thoughts on
providing incentives so that we do sufficiently provide some
balance here as well for those that are actually in the
industry.
Mr. Stephenson. I am not following exactly what you mean.
Ms. Solis. Well, in many cases, we have--some of our water
districts, for example, in my area in the San Gabriel Valley
provide many outreach efforts and incentives to try to inform
the community about conservation, about the importance of
drinking water, the quality.
Might there be opportunities to allow for some incentives
to be set aside for that particular basis to provide for more--
how could I say--sustained funding for some of our water
purveyors who are also in many cases feeling the pinch, the
economic pinch, and especially of monies that are not readily
coming out of our Federal Government into the States. That
obviously has an impact.
Mr. Stephenson. Yes. I would say that sounds like a good
idea. Again, there are--at the Federal level, there are non-
discretionary grants, and several of those go to water
facilities for doing exactly what you are talking about, better
education, better communication, training, etcetera. So it is--
although not embodied in the Safe Drinking Water Act revolving
fund per se--within that limit of the 15 percent or so that is
allowed for education and outreach activities.
Ms. Solis. I want to also thank you for making yourself
available to our staffs for your work.
Mr. Stephenson. You are welcome.
Ms. Solis. Thank you.
Mr. Gillmor. The gentleman from Idaho.
Mr. Otter. Thank you, Mr. Chairman.
Mr. Stephenson, some folks have been arguing that more
funding in the drinking water loan fund for the Washington area
system to access would have averted this problem. Is that your
opinion?
Mr. Stephenson. Say that again.
Mr. Otter. That more money in the fund, the loan fund,
would have actually averted this problem.
Mr. Stephenson. I don't think you can draw that conclusion.
Again, the fund----
Mr. Otter. But isn't that the conclusion that folks,
including at least the direction of some of the questions from
the previous questioners----
Mr. Stephenson. It seems so. But, again, the revolving fund
is allocated on specific formulas as laid out in the Safe
Drinking Water Act. The States all know what they are going to
get as does the District of Columbia.
Mr. Otter. Precisely. And as quick and as, you know, that
you can remember, what is the actual record on the amount of
money that Bush has asked for and that Clinton asked for?
Mr. Stephenson. In total?
Mr. Otter. Yes.
Mr. Stephenson. It has been $850 million a year from the
Bush Administration I think consistently.
Mr. Otter. And how much from the Clinton Administration?
Mr. Stephenson. I don't have that exactly. When----
Mr. Otter. Well, let me just ask this----
Mr. Stephenson. In 1997, the Clinton Administration offered
$1.275 billion, and then it was $725-, $775-, $820-.
Mr. Otter. So, you know, it could be even less that the
Clinton Administration asked for, and not as may have been
suggested that Bush has caused the fund to go anemic.
Mr. Stephenson. Well, unless you adjust for inflation, then
you could probably argue that the Clinton Administration has
provided a little bit more funding.
Mr. Otter. Thank you.
Mr. Stephenson. But it has been very similar.
Mr. Otter. Thank you, Mr. Chairman.
Similar, is your opinion, though.
Mr. Stephenson. Yes.
Mr. Otter. Thank you, Mr. Chairman. I yield back.
Mr. Gillmor. The gentleman yields back.
And, Mr. Stephenson, very much appreciate the work that you
have done on this issue and for being here. Thank you.
Mr. Stephenson. Thank you.
Mr. Gillmor. We will ask our panelists on panel three if
they could come forward.
I want to welcome the panelists. We appreciate all of you
being here, and we will go straight to your testimony. And
first would be Jay Rutherford, who is the Director of Water
Supply Division, State of Vermont, representing the Association
of State Drinking Water Administrators.

HOSPITAL MEDICAL CENTER
Mr. Rutherford. Good morning, Mr. Chairman, and committee
members. My name is Jay Rutherford. I am Director of Vermont's
Drinking Water Program. I am also the past President of the
Association of State Drinking Water Administrators or ASDWA,
and I am speaking to you today on its behalf.
ASDWA represents the drinking water programs in all 50
States and territories in their efforts to ensure the provision
of safe drinking water to more than 275 million consumers
nationwide. Today I will talk about three key things. First is
concerns related to the lead and copper rule. Second is
strategic approaches to meeting water infrastructure needs. And
the third is the consideration of State needs to meet Safe
Drinking Water Act requirements.
Based on the recent events here in Washington, DC, States
have reviewed the performance of water systems in their States,
and we have found that the events here are not reflective of a
widespread national issue. Nevertheless, States would like to
work with EPA and other stakeholders to review the lead and
copper rule and ensure that the public is protected from lead
in drinking water.
Overall, we believe that the general basis to the lead and
copper rule, which is a treatment technique rule as opposed to
a maximum contaminant level, is appropriate, and that the rule
does not require major revisions. We do think that certain
aspects of the rule may need adjustment and streamlining,
however.
EPA, States, and local communities should buildupon
existing programs to educate the public about the hazards of
lead and the various routes of lead exposure. States would also
consider additional regulatory or policy changes to address
lead at sensitive sites such as schools and daycares. And,
finally, States think EPA should investigate whether the so-
called lead-free standard of 8 percent lead content is too
high, and, if feasible, to seek its reduction.
In addition to existing regulations, there are a number of
emerging contaminants such as perchlorate and TBE that need to
be tracked and addressed in order to continue to ensure public
health protection. States support the overall structure set
forth in the 1996 amendments to the Safe Drinking Water Act for
addressing emerging contaminants.
However, where there are contaminants of nationwide
significance that may warrant national regulatory efforts, we
urge EPA to resolve the various scientific and engineering
issues as quickly as possible to eliminate the need for State-
by-State individual standards.
Turning to the issue of funding for drinking water
infrastructure, States believe that the drinking water State
revolving loan fund program, in place for less than 10 years,
has been a real success story in funding infrastructure
improvements as well as providing funds for key elements of the
Act's implementation.
We believe that the drinking water SRF should continue to
be the primary funding vehicle for infrastructure projects
rather than create new ones. Additional funding is certainly
needed, and we encourage Congress to direct such funding to the
drinking water SRF, since States are in the best position to
determine priority of projects and to work directly with water
utilities.
Among the more challenging utility issues are those posed
by small and very small systems, which have poor economies of
scale and are thus often hit hard by new regulations or
infrastructure requirements. States are very sensitive to the
concerns of these systems, but believe that the most
appropriate way to address their needs is through the existing
structure of the Act, including a number of special provisions
with the drinking water SRF.
Given the importance of this program, States believe that
the drinking water SRF program should be reauthorized,
preferably for at least 10 years, and it be adequately funded.
Through 2003, the drinking water SRF has only been funded at 58
percent of the authorized level. In addition, our written
testimony identifies several no-cost structural changes to the
Act that we think are needed to allow more efficient and
effective use of appropriated funds.
My third theme today is State drinking water resources. It
is a favorite of mine. Our State programs are facing the same
type of crisis as the utilities they oversee. We oversee
ongoing compliance and technical assistance efforts for over
160,000 water systems. States are also working on an array of
proactive initiatives to protect public health from source to
tap, ranging from source water assessments and controls to
technical assistance with treatment and distribution, and
finally to--through efforts to improve overall system capacity.
And, further, since September 2001, State drinking water
programs have worked with all of our public water systems to
ensure that critical drinking water infrastructure is
protected. States need to do all of these activities and take
on new ones, while responding to pressures at home to further
cut their budgets and streamline their workforces.
In the current economic climate, State drinking water
programs can no longer sustain, much less increase, their
productivity without adequate Federal support. In the 2003
report, ASDWA documented a shortfall of approximately $230
million between the funds available to the States and the
amount that they felt was needed to fully implement the State
drinking water programs. This gap is projected to grow to
approximately $370 million in 2 more years.
Mr. Chairman, a strong drinking water program supported by
the Federal-state partnership will ensure that the quality of
drinking water in this country will not deteriorate, and will,
in fact, continue to improve, so the public can be assured that
a glass of water is safe to drink no matter where they live or
travel.
States are willing and committed partners to this process.
Additional Federal financial assistance is needed, however, to
meet new regulatory and security needs. We appreciate the
opportunity to meet with the subcommittee today, and we are
ready to work with you and your staff to ensure the continued
protection of public health through safe drinking water.
Thank you.

Prepared Statement of Jay Rutherford, Director, Water Supply Division,
Vermont Department of Environmental Conservation on Behalf of the
Association of State Drinking Water Administrators
INTRODUCTION
Good morning. My name is Jay Rutherford and I am the Director of
the Water Supply Division for the Vermont Department of Environmental
Conservation. I am here today as the past President of the Association
of State Drinking Water Administrators (ASDWA). ASDWA represents the
drinking water programs in each of the fifty states and territories in
their efforts to ensure the provision of safe, potable drinking water
to more than 275 million consumers nationwide. ASDWA's primary mission
is the protection of public health through the effective management of
state drinking water programs that implement the Safe Drinking Water
Act (SDWA). My focus for today's testimony revolves around three key
themes:
Addressing concerns related to the Lead and Copper Rule
Strategic approaches to meet water infrastructure needs
Consideration of state needs to meet Safe Drinking Water Act
requirements
CHALLENGING ISSUES FOR STATE DRINKING WATER ADMINISTRATORS: LEAD AND
COPPER RULE; EMERGING CONTAMINANTS
The Lead and Copper Rule
There are an array of very challenging elements that comprise state
drinking water programs. Among the more challenging is the lead and
copper rule. Based on the recent events in Washington, D.C., states
have reviewed the performance of water systems in their states and
determined that the events in our nation's capitol are an isolated
anomaly and not indicative of a wide-spread national issue.
Nevertheless, states welcome the opportunity to work with EPA and other
interested stakeholders to review the Lead and Copper Rule and ensure
that the public is protected from lead in drinking water. Overall,
states believe that the general construct of the Lead and Copper Rule
is appropriate and that the rule does not require major revisions. Key
state perspectives on the Lead and Copper Rule include:
Action Level, Not an Maximum Contaminant Level (MCL): The rule
construct should retain an action level for lead (as opposed to
setting an at-the-tap MCL for lead).
Public Education: EPA, states, and local communities should build
upon and enhance existing programs to educate the public about
the hazards of lead and the different ways people are exposed
to lead.
Need for Research: Additional research is needed to better understand
some of the key issues related to lead in drinking water and
remediation options.
Definition of ``Lead-Free'': EPA should investigate whether it would
be feasible to reduce the lead percentages included in the SDWA
that pipes and fittings can contain and still be considered
lead-free (currently 8.0%) and, if it is deemed feasible, work
with Congress to amend the SDWA accordingly. In addition,
Congress and EPA should review the current statutory and
regulatory provisions and time frames with respect to lead
service line replacement.
Lead in Schools and Day Cares: States would consider changes to
existing approaches to better address lead at sensitive sites
such as schools and day cares, but believe that these
facilities should be addressed separately from the typical
distribution system requirements.
Emerging Contaminants
In addition to existing regulations, there are a host of emerging
contaminants--such as perchlorate and MTBE--that need to be tracked and
addressed in order to continue to ensure public health protection.
States support the overall structure set forth in the 1996 amendments
to Safe Drinking Water Act (i.e., the Contaminant Candidate List) for
addressing emerging contaminants. However, where there are contaminants
of nationwide significance that may warrant national regulatory
efforts, states urge EPA to resolve the various scientific and
engineering issues needed for national determinations as expeditiously
as possible. States often don't have the luxury of waiting for the
deliberative process to play out at the national level and are often
forced to expend resources to develop their own regulatory levels in
the interim.
STRATEGIC APPROACHES TO MEETING DRINKING WATER INFRASTRUCTURE NEEDS
Turning to the issue of funding for drinking water infrastructure,
I would like to touch upon state perspectives on the Drinking Water
State Revolving Loan Fund (DWSRF) program. We believe the DWSRF, a
proactive program in place for less than 10 years, has been a real
success story in funding infrastructure improvements as well as
providing funds for key elements of SDWA implementation. Based on this
success, we believe that the DWSRF should continue to be the primary
funding vehicle for construction of drinking water infrastructure. We
do not believe that creating new funding vehicles would comport well
with the momentum developed by the DWSRF program. While additional
funding is certainly needed, we would encourage Congress to direct such
funding to the DWSRF program. States are in the best position to
determine the priority of projects for support by the DWSRF and to work
directly with water utilities in this regard.
Among the more challenging utility issues are those posed by small
systems. Small systems frequently have poorer economies of scale and
thus are often hard hit by new rule provisions and associated
infrastructure requirements. States are very sensitive to the concerns
of these systems, but believe the most appropriate way to address their
needs is through the existing structure of the SDWA, including a number
of special provisions of the DWSRF. For instance, loan subsidies as
described in the current statute, including--principal forgiveness, may
be necessary for--disadvantaged communities, particularly small
communities.
In light of the importance of this program, states believe that the
DWSRF program should be reauthorized for a significant period of time,
preferably at least ten years. This will enable firm, long-term
commitments to be made by states to support the program. In view of the
current uncertainties about the duration of the program into the
future, it is exceedingly difficult for state drinking water program
managers to commit the staff and resources needed to support this
program over the long term. Although the SDWA authorized a total of
$9.6 billion for Fiscal Years 1995 through 2003, only $5.52 billon was
appropriated through Fiscal Year 2003. [Need to update this figure for
2004.]
In addition to a long term reauthorization of the fund, states
believe that there are several non-monetary, structural changes in the
SDWA that are needed to allow more efficient and effective use of
appropriated funds. We recommend that Congress make several specific
changes to the DWSRF portion of the SDWA as follows:
Remove the additional matching requirements (beyond the 20% match
already required for the fund) from the 10% set-aside for
undertaking certain state drinking water program activities.
Increase allowable set-aside usage for loan administration from 4% to
6% and allow this set-aside to be used for loan administration
or other eligible uses.
Expand the allowable uses of the 15% set-aside funds related to
source water assessment programs to include updating
assessments and undertaking implementation activities
associated with source water protection areas.
Extend the time interval between the Needs Surveys from the current
four years to six years, with an option for states to perform
more frequent surveys if they so desire.
In addition to these specific changes, we also advocate a number of
other non-legislative changes in the way that the DWSRF program is
administered. We would recommend, for instance, that the administrative
requirements for use of the fund (largely addressed in Federal
regulations and guidance) be as streamlined as possible.
STATE DRINKING WATER PROGRAM NEEDS TO MEET SDWA REQUIREMENTS
So, how does all of this affect state drinking water primacy
programs? The short answer is that states are facing the same type of
crisis as the utilities that they oversee.
States are responsible for oversight of ongoing regulatory
compliance and technical assistance efforts for 160,000 public water
systems to ensure that potential health based violations do not occur
or are remedied in a timely manner. States are also implementing an
array of proactive initiatives to protect public health from ``source
to tap''--including source water assessments and controls; technical
assistance with water treatment and distribution; and enhancement of
overall water system capacity. Further, since September 2001, state
drinking water programs have accepted additional responsibilities to
work with all public water systems to ensure that critical drinking
water infrastructure is protected and that plans are in place to
respond to a variety of possible emergency scenarios.
States must accomplish all of these activities and take on new
responsibilities while responding to escalating pressures to further
cut their budgets, streamline their workforces, and operate with less
state-provided financial support. State drinking water programs have
always been expected to do more with less and states have always
responded with commitment and ingenuity. However, in the current
economic climate, state drinking water programs can no longer sustain--
much less increase--their productivity without Federal support.
Data to support this crisis condition can be found in the 2003
document entitled Public Health Protection Threatened by Inadequate
Resources for State Drinking Water Programs: An Analysis of State
Drinking Water Programs Resources, Needs, and Barriers. This
compilation of a 50-state self analysis documents a shortfall of
approximately $230 million between the funds available to states and
the amount needed to fully implement state drinking water programs.
This ever-widening gap is projected to grow to approximately $370
million by 2006.
Historically, state drinking water programs have received
approximately 85-87 percent of authorized funding levels to support
their SDWA mission. States must contribute a 25 percent match to be
able to receive Federal PWSS program funds for regulatory oversight and
20 percent to receive their DWSRF funding allocation. Because the needs
are so great, states also bring additional dollars to the table through
fee programs, general fund allocations, and other sources. However,
many states no longer have the luxury--or ability--to continue to
overmatch their contributions to support and sustain Federal programs.
Let us not forget that the point of all of this is public health
protection. A strong drinking water program supported by the Federal-
state partnership will ensure that the quality of drinking water in
this country will not deteriorate and, in fact, will continue to
improve--so that the public can be assured that a glass of water is
safe to drink no matter where they travel or live. States are willing
and committed partners. Additional Federal financial assistance is
needed, however, to meet new regulatory and security needs. In 1996,
Congress provided the authority to ensure that the burden would not go
unsupported. In 2004, ASDWA asks that the promise of that support be
realized.
ASDWA appreciates the opportunity to provide this testimony to the
Subcommittee for its consideration and stands ready to work with the
Subcommittee to ensure the continued protection of public health
through provision of safe drinking water.
Mr. Gillmor. Thank you very much, Mr. Rutherford.
Brian Ramaley, who is Director of the Newport News
Waterworks and representing the Association of Metropolitan
Water Agencies.
Mr. Ramaley?
STATEMENT OF BRIAN L. RAMALEY
Mr. Ramaley. Thank you, and good morning. My name is Brian
Ramaley. I am the Director of Newport News Waterworks.
Mr. Gillmor. I apologize, Mr. Ramaley, for----
Mr. Ramaley. That is quite all right. I am testifying
today, as the chairman indicated, on behalf of the Association
of Metropolitan Water Agencies, or AMWA, on whose Board of
Directors I serve.
Newport News Waterworks is a regional water provider for
400,000 people in southeastern Virginia. AMWA is a nonprofit
organization of the largest publicly owned drinking water
systems in the United States, whose members collectively serve
more than 110 million Americans with safe drinking water.
Lead in drinking water typically comes from lead service
lines or lead fittings, fixtures, or solder in home plumbing.
EPA's lead and copper rule required large water agencies to
optimize their systems to reduce the corrosive characteristics
of their water with respect to lead. If, after optimizing, a
system still finds lead at more than 15 parts per billion in 10
percent or more of home tap water samples, it must reduce lead
exposure through public education and replacing the lead
service lines it owns.
This regulatory approach recognizes that corrosion control
through chemical treatment is a very effective way for water
systems to minimize lead exposure. For example, using zinc
orthophosphate as a corrosion inhibitor and adjusting pH, my
utility, Newport News Waterworks, which disinfects with
chloramines, was able to lower our lead levels at our
customers' taps to below detection limits. Our 90 percent level
is below detection limits, and well below EPA's action level.
Lead service line removal can also be effective in reducing
lead exposure, but water systems rarely, if ever, have control
over the customer's portion of the lead service line or the
customer's indoor plumbing, which are private property. Paying
for the replacement of both the public and private parts of a
service line present significant economic and legal burdens for
community water systems.
The national cost to replace the 2 to 5 million lead
service lines in the United States would be between $13 and $18
billion today, estimated, for both the public and private
service lines, not including indoor plumbing. Some utilities
have proactively replaced their lead service lines, but others
have not had the resources to do so.
Newport News Waterworks replaced all of our more than 1,000
known lead service lines before for the lead and copper rule
took effect in the early 1990's. However, in older cities with
many more lead service lines, it has not been possible for
those cash-strapped utilities facing huge infrastructure needs
to do so.
The current monitoring and response requirements have
worked well in most municipalities and reduced lead exposure
through drinking water. Those systems experiencing difficulties
have many successful models to follow, and EPA and the States
have the authority to step in where necessary. An issue that
makes compliance difficult, however, is the level of lead
contained in, and leaching from, home plumbing fixtures.
The 1996 amendments to the Safe Drinking Water Act allow
plumbing manufacturers to establish their own voluntary
standard for leaching from their fixtures. The leaching level
they chose was 11 parts per billion as compared to EPA's action
level at the tap of 15 parts per billion. And the Act defines
lead-free, as has been mentioned here previously for fixtures,
as containing as much as 8 percent lead. These are areas that
clearly offer opportunity for improvement.
Lead service line removal is only one of many
infrastructure costs confronting the Nation's drinking water
systems. EPA estimates that drinking water systems will need to
spend $154 to $446 billion to replace aging infrastructure
through the year 2019. But there are many other national
estimates of similar magnitude.
Regulatory mandates are also driving infrastructure
spending needs upward. New regulations protect public health
and the environment, but they come with enormous costs that
must be paid. Looming investments for local water agencies to
protect their facilities and consumers from potential terrorist
attacks add to the cost of water infrastructure. Security
consultants estimate that water systems in the U.S. that serve
100,000 or more people will have to spend more than $1 billion
on security measures alone, and some estimates are even higher.
Despite the needs of large municipal systems, most Federal
drinking water assistance is reserved for smaller water
systems. We encourage Congress to increase its assistance to
metropolitan systems that have received only 5 percent of
drinking water State revolving funds allocated since the
program started, despite those systems accounting for 20
percent of the targeted need.
Thirty States do not provide any assistance whatsoever to
metropolitan systems. With increased funding, water systems
will endure fewer main breaks, safer drinking water, and
cleaner drinking water sources. Significant investments must
come from the national economy through a long-term funding
source. Increased Federal assistance for water infrastructure
helps protect public health but also increases jobs--about
47,500 jobs for every billion dollars spent on infrastructure.
We appreciate this committee's attention to the serious
matter of drinking water, and we hope that you and your
colleagues in the House and Senate can develop a mutually
acceptable proposal for the sake of safe drinking water and
American jobs.
Thank you.

Prepared Statement of Brian L. Ramaley, Director, Newport News
Waterworks, Va. on Behalf of the Association of Metropolitan Water
Agencies
INTRODUCTION
Good afternoon. Thank you for inviting us to testify and for your
interest in drinking water infrastructure.
My name is Brian Ramaley. I am the Director of the Newport News
Waterworks and an officer and board member of the Association of
Metropolitan Water Agencies, on whose behalf I am testifying today.
Newport News Waterworks is the regional water provider for Hampton,
Newport News, Poquoson and parts of York and James City counties. We
serve safe drinking water to 400,000 people in southeastern Virginia.
The Association of Metropolitan Water Agencies (AMWA) is a
nonprofit organization of the largest publicly owned drinking water
systems in the United States. Our members collectively serve more than
110 million Americans with safe drinking water.
LEAD
Lead that is found in tap water can originate from three sources:
lead service lines, which are the smaller pipes running from water
mains to customer meters; home plumbing fixtures; and lead solder in
the home.
Under the U.S. Environmental Protection Agency's Lead and Copper
Rule, water agencies serving 50,000 or more people must optimize their
systems to reduce corrosivity. If, in spite of optimization, a system
still detects more than 15 parts per billion (ppb) in 10 percent of
home tap water samples, it must reduce lead exposure by educating the
public and replacing the lead service lines it owns. (Samples are
collected at the customer's tap after the water sits unused for several
hours, typically first thing in the morning. This is intended to
represent the worst case for potential lead exposure in that particular
residence. The number of samples required and the frequency of
collection are based on the size of the water system and past results.)
The regulatory approach laid out in the Lead and Copper Rule
recognizes that corrosion control--through the use of chemical
corrosion inhibitors and pH adjustment--has been determined to be a
very effective way for water systems to minimize lead exposure from
homeowners' plumbing fixtures and lead service lines. For example, by
using a zinc and phosphate-based corrosion inhibitor and carefully
controlling pH, Newport News Waterworks, which disinfects with
chloramines, has limited lead levels at our customers' taps at well
below the EPA action level and in most cases below detectable amounts.
The Lead and Copper Rule also recognizes that water systems rarely,
if ever, have direct control over the customer's portion of the lead
service line or the customer's indoor plumbing. Lead service line
removal can be effective, but removing the whole line can be
problematic, and replacement of the customer's portion of the service
line is not currently required under the law. Replacing the customer's
portion of the service line (on private property) requires the
homeowner's permission, which is not always provided in spite of high
lead levels. Agreeing with a homeowner to not replace his or her
private plumbing may leave the water system open to legal claims by
other inhabitants or the house's future owners, particularly if legal
requirements for service line replacement are extended to include the
homeowner's private line in the future.
What's more, paying for the removal and replacement of customers'
lead service lines presents a significant burden on water systems--most
of which are part of local government. In many cases, the water utility
was not responsible for installing a lead service line on private
property. Contractors and developers may have used lead service lines.
Regardless, the bottom line is that the part of the service line on a
homeowner's property is just that--the homeowner's property. Therefore,
while the utility may do the work, the cost of replacing the whole line
should be shared by the utility and the homeowner in proportion to the
work required on public and private property.
Lead service lines were commonly used until about 70 years ago,
because they were relatively less expensive than other options and very
malleable. In 1897, about half of all American municipalities had lead
services lines. When they are found today, they are typically connected
to very old homes. According to a 2002 survey by the American Water
Works Association (AWWA), 56 percent of existing customer service lines
are made of copper while only 3.3 percent are made of lead.
According to a 1994 American Water Works Association Research
Foundation (AwwaRF) report, there were, at that time, between 2.3
million and 5.1 million lead service lines in use in the United States.
The national cost to replace the lead service lines under the control
of both the utilities and homeowners was estimated to be between $10
billion and $14 billion in 1994 (or between $13 billion and $18 billion
today).
Some utilities have aggressively targeted replacement of lead
service lines under their control, but others have not had the
resources to do so. Newport News Waterworks replaced more than 1,000
known lead service lines before the Lead and Copper Rule took effect.
Any newly discovered lines are replaced immediately in our system.
However, in older cities with many more lead service lines, this has
not been economically viable for cash-strapped utilities facing huge
infrastructure needs.
With regard to lead, it is clear to AMWA and its members that
mandating replacement of privately owned lead plumbing will create
financial and operational difficulties for many utilities. Currently
mandated monitoring and response mechanisms have worked well in most
municipalities to reduce lead exposure to our consumers. Recent EPA
data show that less than four percent of 7,702 systems that each serve
more than 3,300 people have exceeded the action level for lead since
2000. Those systems experiencing difficulties have many successful
models to follow and are proceeding quickly down that path.
Increasing exposure and making compliance difficult, however, is
the level of lead contained in and leaching from home plumbing fixtures
into consumers' homes. The 1996 amendments to the Safe Drinking Water
Act allowed plumbing manufacturers to establish their own voluntary
standard for leaching from their fixtures. The leaching level they
chose was 11 parts per billion. And the Act defines ``lead-free''
fixtures as containing as much as eight percent lead.
DRINKING WATER INFRASTRUCTURE NEEDS
The infrastructure needs confronting the nation's drinking water
systems are enormous. The Water Infrastructure Network (WIN) report,
Clean & Safe Water for the 21st Century, and its follow up, Water
Infrastructure Now: Recommendations for Clean and Safe Water in the
21st Century, estimate that drinking water utilities across the nation
collectively need to spend about $24 billion per year for the next 20
years on infrastructure, largely for buried pipelines, for a total of
$480 billion. WIN's analysis also concluded that drinking water systems
currently spend $13 billion per year on infrastructure, leaving an $11
billion annual gap between current spending and overall need.
In the Environmental Protection Agency's 2002 infrastructure gap
analysis, the agency estimated that drinking water systems will spend
between $154 billion and $446 billion through 2019.
According to a 2002 survey by AMWA, 32 metropolitan systems alone
reported that they must spend $27 billion over the next five years on
drinking water and wastewater infrastructure. For instance, Cleveland,
Ohio must spend up to $700 million; Columbus, Ohio, $253 million; New
Orleans, $1.2 billion; Kansas City, Mo., over $500 million; Denver,
$363 million; Chicago, $600 million; Austin, $568 million; Phoenix,
$1.28 billion; and Omaha, Nebraska, $355 million. In 2002, Detroit
reported that its capital expenditures for drinking water projects
would be $1.4 billion over the next five years and $2.9 billion would
be spent for wastewater projects. Washington, D.C. will have to spend
almost $2 billion over the next 10 years, plus more than a billion
dollars to meet EPA wet weather requirements.
The total length of pipe for water mains in the United States is
nearly 900,000 miles, according to AwwaRF. Age is the primary reason we
are confronted with such high estimates of infrastructure spending
needs. From the late 1800s to the late 1960s, most water mains were
made of cast iron. Now much of that pipe has reached the end of its
life, and water systems are more often experiencing main breaks and
water loss. AwwaRF estimates there are approximately 238,000 water main
breaks each year and, on average, water systems lose 10 percent of
their treated drinking water, mostly due to deteriorated pipes.
Newport News Waterworks has nearly 2,000 miles of pipeline in its
system. Our capital investment needs, though small compared to the
cities I just listed, have averaged more than $10 million dollars per
year over the last fifteen years.
Regulatory mandates are another reason for such high infrastructure
spending needs. New drinking water regulations to remove arsenic from
drinking water and to control microbial contamination and disinfection
byproducts will better protect public health, but they come with
enormous costs.
WATER SECURITY
Compounding these financial burdens are the looming investments
local water agencies will be forced to make to help protect their
facilities and consumers from potential terrorist attacks. The American
Water Works Association estimates that water systems will need to spend
approximately $1.6 billion on immediate next steps. These steps include
fencing around facilities and reservoirs, security doors and locks,
intruder alert systems, better lighting, surveillance cameras to
monitor entry ways and sensitive facilities, access control and
barricades around key facilities. Some systems already have some or all
of these measures in place, while others are in the process of
installing them.
According to security consultants in the water sector, studies of
17 large utilities project overall security costs ranging from $750,000
to $91 million, averaging $15.5 million per utility. AMWA roughly
estimates that water systems will spend an average of $8 to $11 per
individual in a service area to improve security. Another study by
security consultants estimates that the 450 drinking water systems in
the United States serving 100,000 or more people will have to spend
approximately $1.2 billion to harden their facilities against possible
attacks.
METROPOLITAN WATER SYSTEMS
Most federal drinking water assistance is reserved for smaller
water systems, and we encourage Congress to increase its assistance to
metropolitan systems--systems serving 100,000 people or more. Programs
at USDA serve only rural systems, and EPA's drinking water state
revolving fund (SRF) is primarily used to resolve regulatory compliance
problems at small systems. According to EPA, metropolitan systems
received only five percent of drinking water SRF assistance, even
though these systems accounted for 20 percent of the estimated needs.
Thirty states do not provide any assistance to metropolitan systems.
There are two key reasons why metropolitan water systems do not
benefit from the drinking water SRF. First, the Safe Drinking Water Act
directs drinking water SRF funding to systems unable to meet drinking
water regulations and protect public health. The more common problem
metropolitan systems face is simply the need to replace aging
infrastructure. And while aging infrastructure can contribute to public
health concerns, the drinking water SRF primarily assists small systems
facing acute problems. The second reason metropolitan systems do not
benefit from the drinking water SRF is that there just isn't enough
money in the program.
Even while the drinking water SRF program is authorized at the
relatively modest amount of $1 billion, EPA has not asked for and
Congress has not appropriated more than $850 million for the program.
SOLUTIONS
A lack of increased federal infrastructure funding risks
jeopardizing public health and the security of our infrastructure. Safe
drinking water is the first line of defense against deadly waterborne
viruses, and adequate infrastructure is the key component in the
effort. Furthermore, with increased funding, water systems will endure
fewer main breaks and better protect our families from security
threats.
To pay these large infrastructure costs, drinking water systems
across the country will need to rely on a multi-pronged approach
consisting of rate increases, federal and state funding, asset
management, consolidation and regionalization, and more efficient use
of water, among others.
Water rates are increasing all over the country, but household
budgets can only absorb so much. Publicly owned utilities are also
becoming more efficient, and most are engaged in asset management
programs to help prepare for the future. Beyond these steps, the
solutions must include a significant investment from the resources of
the nationwide economy through a long-term funding source. An expanded
national commitment would account for the external costs endured by
utilities, such as the cost to treat nonpoint source agricultural
pollution, MTBE and perchlorate.
EPA's solution to the infrastructure crisis is to encourage
administrative improvements at utilities. This and rate increases will
help to some extent, but they will never be enough. That's why AMWA and
its 50 other coalition partners in the Water Infrastructure Network
strongly urge Congress to pass bipartisan legislation to significantly
increase federal assistance to drinking water and wastewater systems,
particularly those serving metropolitan areas.
Not only will increased federal assistance help protect public
health and the environment, but it will also increase jobs. According
to government leaders, about 47,500 jobs are created for every $1
billion spent on infrastructure in the United States.
We appreciate your attention to the serious matter of drinking
water infrastructure. We hope that you and your colleagues in the House
and Senate can develop a mutually acceptable proposal for the sake of
safe drinking water and American jobs.
Mr. Gillmor. Thank you, Mr. Ramaley.
And the next witness is Aaron Colangelo, who is Staff
Attorney for the National--Natural--National Resources Defense
Council, otherwise known as NRDC.
Mr. Colangelo?
STATEMENT OF AARON COLANGELO
Mr. Colangelo. Mr. Chairman, and members of the
subcommittee, thank you for the opportunity to testify. I am
Aaron Colangelo. I am a Staff Attorney with the Natural
Resources Defense Council. NRDC is a national, nonprofit,
public interest organization with over 500,000 members, and the
NRDC is dedicated to protecting public health in the
environment.
In response to high lead levels in DC water, WASA and EPA
both missed opportunities to control the contamination in DC,
both violated drinking water regulations and Federal law, and
both failed to notify the public of the health threats in a
timely or meaningful way. In light of these failures, Congress
should require EPA to establish an MCL, or maximum contaminant
level, for lead, which will create a clear and enforceable
legal limit for lead contamination.
In addition, as many witnesses and members have noted
earlier this morning, a deteriorating drinking water
infrastructure in the country has contributed to this public
health crisis, and has increased the challenge of providing
safe and affordable drinking water.
Significant targeted expenditures are necessary, and this
could include creative financing and creative utility
management options to start meeting some of these mounting
infrastructure needs. Finally, a comprehensive reauthorization
of the Safe Drinking Water Act is necessary to fund key
components of the Act, including national primary drinking
water regulations, State revolving funds, technical assistance
to small water systems, and other provisions.
Full funding for each of these programs, and many others,
is integral to successful implementation of the Safe Drinking
Water Act, and authorization for each of them expired in 2003.
EPA testified earlier this morning that lead contamination
is not a national problem. However, EPA's survey of medium and
large water systems found that at least 10.2 million people are
served by systems that have lead contamination problems, and
these are the numbers with only 80 percent of the survey
results in so far. NRDC believes that this is a national
problem with lead in drinking water, and it deserves EPA's full
and immediate attention.
Earlier witnesses--Mr. Johnson from WASA--mentioned that
the WASA Board commissioned Eric Holder and a team of his
colleagues from Covington and Burling to review the lead in
drinking water crisis in DC and to make recommendations to help
prevent future problems. The Holder report outlines dozens of
missteps by both WASA and EPA.
Among the most striking findings of the Holder report is
that WASA considered ways to manipulate the lead in drinking
water numbers at least four times over the past 4 years, and
this is another reason that an MCL, or maximum contaminant
level, is a more effective and better and less manipulable
standard. In particular, WASA improperly invalidated five
samples in 2000 to 2001, any of which, had they been included,
would have caused WASA to exceed the lead action level in 2000
and may have brought this issue to the public's attention years
earlier.
There are other indications in the Holder report that WASA
considered other types of efforts. For example, testing in the
winter when lower temperatures would mean that lead levels were
lower in the pipes, expanding the sample size to try to dilute
the exceedances, or excluding homes with historically high
levels.
For the first of these, the invalidation of five samples in
the 2000 to 2001 testing period, it is clear that WASA did
that, and there has been no clear explanation why. For the
remaining three, it is unclear whether WASA did eventually
attempt to address the exceedance problems in that way, but the
mere fact that WASA was considering these options is troubling
and demonstrates that WASA may have been more concerned with
the administrative burdens of remedying the lead contamination
problem than with the clear and obvious threat that the
contamination posed to public health in the District. Having an
MCL would prevent this kind of thing from happening.
Also troubling, the Holder report found that, from
reviewing e-mails and other correspondence between EPA and
WASA, EPA often knew of WASA's violations of the lead rule and
endorsed them, and it wasn't until after The Washington Post
expose in January, and the subsequent community outrage, that
EPA reevaluated the situation and declared that WASA had
violated the rules.
As the report finds, EPA's muted response and missed
opportunities materially contributed to the problem. EPA knew
as early as August 2001 that high lead levels were being found
in DC drinking water.
In recent months, WASA has asserted that lead in drinking
water isn't much of a problem, because most people's exposure
to lead comes from other sources. And earlier today Mr. Johnson
of WASA testified that DC's lead problem is not a health
problem, but instead is only a communications issue.
This is incorrect for several reasons. First, the Holder
report found this argument to be a distraction that was part of
WASA's larger efforts to divert attention and downplay the risk
of lead in drinking water. And, second, the CDC has recently
analyzed data from DC and found that there is reason to be
concerned about lead in DC drinking water.
Another reason to be concerned is that this was the same
argument that was used to justify maintaining lead in gasoline
for decades, long past when it had been discovered to be a
significant and wholly avoidable public health problem.
Fourth, as recently confirmed by the CDC, the science is
trending toward the conclusion that very low levels of lead, as
low as 2 or 3 micrograms per deciliter, pose a health problem
and can cause measurable and irreversible health effects.
Also, in response to the argument that the Aqueduct witness
made earlier today, that chloramines were necessary to control
disinfection byproducts, increased lead contamination is not
the necessary outcome of efforts to control other contaminants
like disinfection byproducts. By improving source water
protection, enhancing water infrastructure, and modernizing
treatment technology, the Corps could resolve both of these
risks at the same time.
The suggestion of a tradeoff between higher disinfection
byproducts on the one hand and higher lead levels on the other
presents a false choice. Also----
Mr. Gillmor. Mr. Colangelo, could I ask you to try to wrap
up? Because we are over the time limit, but I also don't want
to cut out anything important you want to say. But if you could
try to wrap up.
Mr. Colangelo. Sure, Mr. Chairman, I will wrap up.
Mr. Gillmor. We heard the definition of ``soon'' earlier,
so hope you can wrap up soon.
Mr. Colangelo. I will wrap up sooner.
I would just like to mention perchlorate quickly. Several
members asked about perchlorate earlier this morning.
Perchlorate is a widespread drinking water contaminant, and it
is incorrect to say that the Superfund office is best equipped
to deal with it. I will just make three quick points, and then
I can--I will be happy to answer any questions about
perchlorate or any of these other issues.
First, perchlorate has been used in 49 States and detected
in the environment in at least 30, and it is not being cleaned
up in many of these States.
Second, there is no MCL for perchlorate. EPA recently
declined to even begin the process of setting an MCL for
perchlorate, and that means that no maximum contaminant level
will come for at least 6 years, which is when the process would
be begun. There is no need to wait for the NAS review before
beginning that process. When the NAS information comes in, it
can be incorporated into the MCL standard-setting process.
And, third, there is a significant problem of EPA and other
government agencies failing to inform the public about
perchlorate contamination. EPA imposed a gag order early last
year barring its scientists from discussing perchlorate. NRDC
has filed 15 FOIA requests seeking information about
perchlorate, which have been stonewalled by EPA, the Department
of Defense, and several White House offices, and we think that
in addition to keeping important information from the public
this is exacerbating a public health threat.
Thank you.

SUMMARY
Lead contamination in the District of Columbia is a significant
public health problem. The D.C. Water and Sewer Authority and the
Environmental Protection Agency both missed opportunities to contain or
remedy this contamination, failed to comply with drinking water
regulations and federal law, and failed to notify the public of the
health threats in a timely or meaningful way. In light of this failure
to respond properly to lead contamination, Congress should carefully
oversee EPA's implementation of its drinking water responsibilities and
insist on full and effective enforcement of the Safe Drinking Water
Act. EPA's inaction in response to lead and other drinking water
contaminants has exacerbated environmental health threats.
Furthermore, a comprehensive reauthorization of the Safe Drinking
Water Act is necessary to fund national primary drinking water
regulations, State Revolving Funds, technical assistance to small water
systems, and other important components of the act. Full funding for
these programs is integral to successful implementation of the SDWA,
and authorization for each of them expired in 2003. Finally, the
nation's deteriorating drinking water infrastructure has increased the
challenge of providing safe and affordable drinking water across the
country and, in the case of lead in D.C., has contributed to at least
one public health crisis. NRDC proposes significant, targeted
expenditures and creative financing and utility management options
below to start meeting some of the mounting infrastructure needs.
Immediate congressional action is necessary to begin to address
infrastructure shortfalls.
I. THE DISTRICT'S LEAD IN DRINKING WATER CRISIS THREATENS PUBLIC HEALTH
AND DEMANDS BETTER OVERSIGHT.
The local drinking water lead crisis poses serious public health
risks to thousands of residents of the national capital area. The
Environmental Protection Agency (``EPA'') has not fulfilled its
obligation to aggressively oversee the safety of D.C.'s water supply,
to ensure that the public is fully apprised of the health threats posed
by lead in drinking water, and to enforce the Safe Drinking Water Act
(``SDWA''). This raises important questions about the adequacy of EPA's
drinking water program not only in D.C., but across the country. The
U.S. Army Corps of Engineers' Washington Aqueduct Division (``Corps'')
has failed to treat the water it delivers to D.C. and neighboring
Northern Virginia communities sufficiently to ensure that the water is
not corrosive, in order to reduce lead contamination. The D.C. Water
and Sewer Authority (``WASA'') failed to act promptly or adequately in
response to the lead contamination crisis, and neglected to adequately
and clearly inform the public about the lead problem. A report
commissioned by the WASA Board of Directors released last week, the
``Holder Report'', concluded that WASA failed to act promptly after it
detected high lead levels in D.C. drinking water, and subsequently
downplayed the scope of the lead contamination and the health threats
it posed in communications with the public. The nation's capital's
water supply should be the best in the world, an international model.
Instead, it is among the worst big city supplies in the nation.
It should not be assumed, however, that Washington is the only city
in the U.S. affected by lead or other important tap water problems.
Although EPA has asserted that lead contamination is not a national
problem, its own survey of medium and large public water systems shows
that up to 10.2 million people are served by utilities with lead
contamination problems. The Lansing, Michigan water utility recently
announced that it is replacing 14,000 lead service lines because of
contamination concerns, and several other cities have struggled with
lead contamination in recent years, including Seattle, greater Boston,
St. Paul, Minnesota, Bangor, Maine, Madison, Wisconsin, Ridgewood and
Newark, New Jersey, Oneida, New York, and many others. Yet EPA
maintains no accurate, up-to-date national information on this issue;
national drinking water databases required by EPA rules are incomplete
and out of date. Furthermore, EPA has failed to address state failures
to comply with federal reporting rules, making effective EPA oversight
and enforcement impossible.
School systems in many cities across the country--including in
Seattle, Boston, Baltimore, Philadelphia, and Montgomery County,
Maryland--have found serious lead contamination problems, but often
have been slow to inform parents and resolve the problem. Many school
systems have entirely failed to comply with the Lead Contamination
Control Act of 1988's mandate to test school water for lead and replace
coolers that serve lead-contaminated water. EPA and many states have
done a poor job of ensuring that the EPA lead rule and the school
testing and cooler programs are fully implemented. Moreover, the
Washington D.C. crisis and experience in other cities highlight that
the EPA lead rule and public education requirements are difficult to
enforce and ultimately ineffective.
Data published by the Centers for Disease Control and Prevention
(``CDC'') recently found that there are--reasons to be concerned
about--lead in D.C. tap water.1 The CDC analyzed 85,000
blood lead screenings reported to D.C. since 1998. Although severe
acute lead poisoning from drinking water exposure was not found, blood
lead levels in D.C. children who drink water in homes served with lead
lines did not decrease, whereas they did decrease in children served by
non-lead lines. This suggests to health experts that lead in tap water
is likely contributing to higher blood lead levels in some children in
the District. As Mary Jean Brown, the lead poison prevention chief at
the CDC, stated to the Washington Post: ``There is no safe level of
lead. Even a small contribution, especially in small children, is not
something that we want to happen . . . We don't want to increase the
blood lead levels of those individuals by even 1 microgram if it can be
prevented.'' Avram Goldstein, Blood Levels Affected by Disinfectant:
Study Cites Impact on D.C. Children, Washington Post at B1 (March 31,
2004). Because of deficiencies in the D.C. blood lead monitoring
program, and because blood lead levels begin to drop fairly shortly
after exposure is stopped (with time, much of the lead deposits in bone
and soft tissue), it is possible that more serious problems were simply
undetected. It is important to note that new data published in major
medical journals the past few years show that the most significant
adverse health effects are seen at levels below 10 micrograms per
deciliter in blood, where lead has been linked to reduced cognitive
function, poor school performance, and learning disabilities in
children.

in Tap Water--District of Columbia (April 2, 2004), online at http://

5312a6.htm.
---------------------------------------------------------------------------
Furthermore, it is incorrect to assert that lead in drinking water
is not a problem because it will comprise only a minority of most
children's total exposure to lead. First, this was the same argument
used to justify keeping lead in gasoline for decades, which is now
acknowledged to have been a major (and wholly avoidable) source of lead
exposure for millions.2 Second, for a significant percentage
of people, their only exposure to lead is through drinking water, and
high levels in drinking water alone can cause health problems. Third,
as noted above and confirmed by the CDC, science is trending towards
the conclusion that very low levels of lead in blood--as low as two to
three micrograms per deciliter--can cause measurable and irreversible
health effects.

Politics of Industrial Pollution at 29, 35 (2002).
---------------------------------------------------------------------------
Below, we summarize some key problems with the responsible
agencies' reactions to the lead crisis, and the actions that need to be
taken to resolve the problem locally and to avoid possible repetition
of the problem nationally:
EPA--The EPA bears a special responsibility for addressing the D.C.
water crisis, because the agency has primary responsibility for
drinking water protection in the city. EPA must go beyond its recent
Consent Order with WASA, discussed below, and take stronger emergency
enforcement action against WASA and the Corps. EPA's dealings with WASA
and the Corps lack the clarity, detail, and enforceability needed to
ensure that this problem is promptly resolved. An enforcement order
should be issued that would both mandate immediate actions to deal with
the lead crisis in the short term, and require a comprehensive top-to-
bottom review of both WASA and Corps operations, with an eye towards
effecting positive structural changes in the long term.
EPA has failed to ensure prompt and accurate public education and
reporting on lead problems, and there are substantial questions,
confirmed in the Holder Report, about whether EPA adequately oversaw
WASA's lead monitoring and sample invalidations. EPA also failed to
promptly and adequately review--or to insist upon updating--the Corps'
corrosion control program. It is unclear whether EPA insisted upon an
adequate and accurate materials survey, and EPA reportedly allowed WASA
to avoid lead service line replacement by taking advantage of a
regulatory loophole.
EPA has been slow to force WASA to redo its invalid school testing,
or to mandate testing of day care centers or private schools. The EPA
lead rule itself, which is drafted in a way that makes it very
difficult to enforce, needs to be substantially strengthened. In
addition, as noted above, EPA's data reporting systems are inadequate,
to the point that EPA management cannot accurately and timely answer
simple questions, such as ``which public water systems are above the
lead action level and which are replacing lead service lines?'' EPA
also has done little to ensure that school testing for lead has been
carried out nationally, perhaps in part due to a court ruling casting
doubt on the constitutionality of the program: Acorn v. Edwards, 81
F.3d 1387 (5th Cir. 1996) (holding that a SDWA provision requiring
states to develop lead testing programs for schools and day care
centers violates the Tenth Amendment as an unconstitutional
conscription of state agencies to perform federal regulatory
functions).
By a Consent Order negotiated last month, EPA and WASA outlined a
list of steps that WASA must take to address the lead contamination
problem. This Consent Order includes basic requirements that
essentially compel WASA to comply with the EPA Lead and Copper Rule in
the future, and take some minor additional steps in an attempt to
redress WASA's past failure to comply. See In the Matter of D.C. WASA,
EPA Docket No. SDWA-03-2004-0258DS, Administrative Order for Compliance
on Consent (``Consent Order''). However, the EPA and WASA Consent Order
falls short of the steps necessary to resolve the D.C. lead in drinking
water crisis. In particular, the Consent Order fails to include any of
the following necessary components:
expedited, valid testing of all schools and day care centers;
expanded testing of multiple family and single family homes and
apartments beyond those with lead service lines;
reissued accurate, understandable notices to consumers of lead
levels, health risks, and options to avoid lead;
professional installation and maintenance of certified filters for
homes with lead service lines or high lead levels in their
water, and that have young children, pregnant women, women who
expect they may become pregnant, and other high risk
individuals;
an aggressive, honest, ongoing public education campaign developed
with public input;
a comprehensive third-party review of all available records and
archives to determine whether the D.C. materials survey
correctly identifies all locations where lead components were
used;
an expedited third-party review of the Corps' corrosion control and
disinfection byproduct control strategy, with mandatory
implementation of solutions by specified dates certain; and
a top-to-bottom third party expert review of WASA and the Corps'
water quality, source water, and overall performance, including
a detailed review of their implementation of past consultant
recommendations, Comprehensive Performance Evaluations, and
sanitary surveys, and recommendations for long-term compliance
with current and upcoming rules and water quality objectives.
The review should seek public input and should be published.
Each of these recommended agency actions was first proposed by a
coalition of public health, environmental, and other public interest
organizations, of which NRDC is a member, in February 2004. For a more
detailed discussion, see the LEAD Coalition recommendations attached at
Appendix A below.
Army Corps of Engineers--The Corps has failed to ensure that its
water is adequately treated to reduce its corrosivity and to thereby
reduce lead levels in Washington and the Northern Virginia suburbs that
it serves. The Corps has repeatedly responded to water quality problems
by adopting the cheapest and often least effective band-aid solutions.
Instead of using orthophosphate or other sophisticated corrosion
inhibiters, as recommended by its consultants, the Corps chose to
simply adjust water pH with lime, a cheaper and apparently less
effective alternative.
In addition, instead of moving towards advanced treatment such as
granular activated carbon filters and UV light or ozone disinfection,
or membranes to reduce cancer-causing (and possibly miscarriage and
birth defect-inducing) disinfection byproducts, and to more effectively
remove the dangerous parasite Cryptosporidium and other contaminants,
the Corps opted for the cheapest and least effective choice. It simply
added ammonia to its chlorine to make chloramines. The switch to
chloramines did slightly reduce chlorination byproduct levels, but also
appears to have increased corrosivity of the water and therefore
increased lead problems. It should be noted that, contrary to the
inaccurate assertions of some critics, the EPA rules setting new limits
on disinfection byproducts were not the result of ``extremist
environmentalist'' efforts, but were negotiated by a diverse regulatory
committee over a several-year period. The committee included major
water utility trade associations, chlorine manufacturers, health
departments, public health experts, states, local officials, and
environmentalists (see 1998 agreement in principle at http://
www.epa.gov/safewater/mdbp/mdbpagre.html). Furthermore, increased lead
contamination is not the necessary outcome of efforts to combat
disinfection byproducts. By improving source water protection,
enhancing water infrastructure, and modernizing treatment technology,
the Corps could resolve both of these risks at the same time. The
suggestion of a tradeoff between higher disinfection byproducts on the
one hand and higher lead levels on the other presents a false choice.
WASA--WASA's response to the lead crisis has been slow, plagued by
misleading statements to the public and to senior D.C. officials, and
often characterized by missteps and non-compliance with EPA rules. EPA
has recently listed six alleged violations of federal regulations that
may have contributed to the lack of public knowledge. See EPA Non
Compliance Letter to WASA, dated March 31, 2004, available online at
http://www.epa.gov/dclead/johnson-letter2.htm. The Holder Report
outlines other clear WASA violations of federal regulations and
thoroughly documents years of WASA inaction and inappropriate action in
response to test results showing high lead levels. In particular, the
Holder Report (at page 88) notes that WASA deliberately changed the
required language in its public service announcements regarding lead
``in ways that downplayed the health issue.''
WASA's conflicting advice to customers (such as a February 9, 2004
letter to all customers telling them to flush their water for 15-30
seconds, followed by a public announcement a few days later to flush
lead lines for 10 minutes, followed a few days later by a
recommendation that pregnant women and children under six served by
lead service lines should use a filter) confused and justifiably upset
citizens. WASA's invalid testing of city schools, in which virtually
all samples were taken after water was flushed for 10 minutes (with the
likely effect of reducing or eliminating lead levels) should be
disregarded, and WASA should instead conduct a valid school and day
care testing program. At the mayor's and EPA's insistence, WASA has now
said it will do additional school testing.
WASA announced on July 1, 2004 that it intends to replace all lead
service lines on public property by 2010, and will encourage homeowners
to replace lead service lines on private property as well. Although
overdue, this is a positive first step. However, since local and
federal authorities have approved and encouraged the private use of
lead service lines in D.C. for over 100 years, we believe that WASA
should fully remove all of the lead service lines at its expense (with
federal assistance, as outlined below), instead of stopping at the
property line. A comprehensive third-party public review of WASA's lead
program and all water quality operations is also needed.
Congress--We urge Congress to help D.C. and EPA to fund the
response to the lead crisis, including lead service line replacement
and upgrades to the D.C. and Corps water infrastructure. Congress also
should respond to the national water infrastructure problem through
national legislation and increased appropriations. In addition,
Congress should vigorously oversee EPA's drinking water program,
including its national implementation of the lead rule and its
enforcement and data collection programs. Members of this Committee
should urge their colleagues on the Appropriations Committee to
increase funding for EPA drinking water programs, and particularly for
drinking water enforcement. We also urge Congress to insist that EPA
take emergency enforcement action against WASA and the Corps, as
discussed below.
Specifically, among the actions that we believe Congress should
take to address problems raised by the lead crisis are:
Water Infrastructure or Grants/Trust Fund Legislation
Congress should substantially increase the Drinking Water State
Revolving Fund authorization and appropriations (now funded at
$850M; authorization of $1B expired in 2003).
Congress should adopt a broad water infrastructure bill and/or water
infrastructure trust fund legislation.
Congress should adopt targeted legislation for lead rule compliance/
lead service line replacement and filters for D.C. residents at
least, since the federal government approved and oversaw the
installation of the lead lines.
Congress should require the Corps of Engineers to pay for D.C. lead
service line replacement, since the Corps built the system and
operates the treatment plant that is providing corrosive water.
Also, federal agents (federally-appointed Commissioners and
engineers) approved and sometimes required lead service lines
in D.C.
Congress should adopt new legislation that provides grants to needy
water systems, like the Gibbons-Udall bill (H.R. 1178, 107th
Congress) and the Reid-Ensign bill (S. 503, 107th Congress),
which would create a small public water system assistance
program to provide technical assistance, help maintain level
costs for consumers, and enable regulatory compliance.
Fix Lead Pipe and Fixtures provision in the SDWA
Congress should redefine ``lead free'' in SDWA 1417(d) to mean
really lead free (i.e. no lead added, and no more that 0.1 or
0.25% incidental lead--as required by Los Angeles and Bangor,
Maine)
Congress should fix the public notice provisions in SDWA
1417(a)(2), which clearly have been inadequate (as shown by the
D.C. experience)
Fix the SDWA lead in schools and day care provisions (SDWA 1461-
1463)
Congress should redefine ``lead free'' in the Lead Contamination
Control Act (LCCA), which added SDWA 1461, to mean really
lead free (0.1% or 0.25%, see above)
Congress should order an EPA review of SDWA 1462 implementation and
effectiveness of lead fountain recall provision in all states
Congress should clarify SDWA 1461-63 to eliminate any doubts about
constitutionality raised by the decision in Acorn v. Edwards,
81 F.3d 1387 (5th Cir. 1996), holding that requiring states to
develop school and day care lead testing plans violates the
Tenth Amendment;
Congress should require ongoing retesting of all schools and day care
centers in light of Acorn and the resulting widespread non-
compliance by states, and new info on lead leaching.
Fix the EPA Lead Rule & Associated Regulations
Adopt a 10 or 15 ppb MCL at the tap. There was an MCL (50 ppb) until
1991.
As a clearly second-best alternative, the EPA lead rule needs serious
overhaul:
Require immediate review of corrosion control programs for systems
that make treatment changes, and also require review
periodically;
Change monitoring requirements so systems cannot go for years without
testing, and to clarify and strengthen test methods, site
selection, and number of tests (50 or 100 per city are not
enough);
Strengthen and overhaul the inadequate public education and public
notice requirements in 40 C.F.R. 141.85;
Require full lead service line replacement, or at a minimum require
water systems that approved, authorized, or required use of
lead service lines to replace those lines if they are
contributing to lead over the action level;
Require in-home certified filters to be provided to high-risk people
who have high lead levels, with water system-supplied
maintenance in accordance with 40 C.F.R. 141.100;
Eliminate the loophole that allows systems to count homes tested at
below 15 ppb as if their lead service lines were replaced
(``testing in lieu of replacement'') in implementing the 7% per
year lead service line replacement provision;
Require an overhaul and upgrade of EPA's compliance & data tracking.
Fix the Consumer Confidence Report & Right to Know Requirements
EPA's right to know and consumer confidence report rules need to be
overhauled and strengthened. WASA's report declared on the
cover ``Your Drinking Water is Safe'' and buried the facts. No
one knew of the problem. Similar problems have been documented
for water systems across the country.
Fix SDWA Standards Provisions
Congress should require that standards protect pregnant women,
children, vulnerable people;
Congress should overhaul the new contaminant selection and six year
standard review provisions. These provisions have been complete
failures since 1996.
II. AGING WATER INFRASTRUCTURE REQUIRES IMMEDIATE ATTENTION AND
SIGNIFICANT FUNDING.
Comprehensive water infrastructure legislation, consistent with
smart growth and water conservation principles, is urgently needed.
Many drinking water quality and affordability problems can be traced to
inadequate and aging infrastructure. As noted above, Congress should
adopt a broad water infrastructure bill or water infrastructure trust
fund legislation. Any infrastructure legislation should preserve public
control of all water assets.
Many cities' water mains and collection systems are 100 years old
or more, according to EPA review. These aging pipes burst, leak 20
percent or more of their water, and can allow bacteria growth or
catastrophic failure leading to contamination. Because of this aging
infrastructure, there are 200,000 water main breaks per year in the
United States.
Over 90 percent of U.S. city water supplies continue to use pre-
World War I technology to treat drinking water, according to an NRDC
analysis of city treatment systems. Existing treatment often fails to
remove significant contaminants from drinking water, including
pesticides such as atrazine, industrial chemicals such as TCE or
perchlorate, and inorganics such as arsenic or nitrates. Old water
system pipes, including lead service lines, often leach lead into
drinking water. Old-fashioned treatment techniques using free chlorine
disinfection create high levels of disinfection byproducts,
contaminants that are known to cause cancer and are linked to higher
rates of miscarriage and birth defects.
About $1 trillion is needed for drinking water and wastewater
infrastructure upgrades and rehabilitation over the next 20 years,
according to the Water Infrastructure Network (a coalition of cities,
states, utilities, and others). The annual funding shortfall for
drinking water investment is about $11 billion--and an additional $12
billion for wastewater investment--according to the WIN study. A 2002
Congressional Budget Office review was more conservative in its
estimates, but still found huge 20-year needs of $232 to $402 billion
for drinking water infrastructure investment, and $260 to $418 billion
for sewage collection and treatment infrastructure needs. These
dramatic water infrastructure funding gaps are outlined in Appendix B,
below.
NRDC endorses both creative financing options and more efficient
infrastructure management to start to resolve this urgent problem.
Increasing State Revolving Fund monies is a necessary first step, and
municipal bond reform could encourage easier and more tax-exempt bond
funding of water infrastructure. NRDC also recommends green bonds--
lower interest federal bonds that could fund infrastructure needs. In
addition, progressive water rates that charge the heaviest industrial
users more per gallon, instead of less, could be used to establish a
water infrastructure trust fund. Finally, incentives for green
infrastructure could provide source water protection and lower-cost
stormwater solutions that would limit the burden on existing drinking
water and wastewater systems.
III. A COMPREHENSIVE REAUTHORIZATION OF THE SDWA IS NEEDED.
It is important that Congress conduct a comprehensive review and
reauthorization of the SDWA as a whole. The 1996 SDWA Amendments
created and authorized numerous new drinking water programs, and
revised and reauthorized many existing programs, but these
authorizations expired in 2003. This subcommittee recently considered a
bill to reauthorize the New York City Watershed Protection Program.
NRDC strongly supports continued funding for this watershed program,
but we also believe that it is critical to reauthorize all of the
important provisions of the SDWA. Each of the following important
authorizations expired in 2003 and have not been reauthorized:
Drinking Water Regulations. The heart of the SDWA's drinking water
program, section 1412 authorizes $35 million/year for studies and
analyses to support the standard-setting program for establishing
national primary drinking water regulations to protect public health.
State Revolving Fund. The biggest expired authorization is $1
billion/year for the drinking water State Revolving Fund, which was
established in section 1452 to allow states to operate revolving funds
that finance loans (and limited grants to disadvantaged communities) to
facilitate compliance with EPA drinking water rules or to significantly
further health protection objectives of the SDWA.
Operator Certification. This program, established in section 1419
by the 1996 SDWA Amendments, authorizes $30 million/year for EPA grants
to states to run programs to ensure the proficiency and certification
of drinking water system operators.
Capacity Development. Another program established by the 1996
Amendments (section 1420), authorizes $5 million/year for small system
technology assistance grants and $1.5 million/year for the small system
capacity development program.
Sole Source Aquifer Demonstration Program. The sole source aquifer
program in section 1427 authorizes $15 million/year for grants to
protect underground aquifers that are the sole or primary source of
drinking water for a region against contamination.
State Wellhead Protection Programs. Section 1428 authorizes $30
million/year for states to develop and implement wellhead protection
programs to defend public water supply wells against contamination.
State Ground Water Protection Grants. The 1996 Amendments
authorized, in section 1429, $15 million/year in grants to states to
develop and implement state programs to ensure coordinated and
comprehensive protection of ground water resources.
Technical Assistance to Small Water Systems. Section 1442(e)
authorizes $15 million/year in funding to assist small systems to
achieve and maintain compliance with national primary drinking water
regulations.
State Grants for Public Water System Supervision Programs. Section
1443(a)(7) authorizes $100 million/year in grants to states to run
their drinking water programs to supervise the safety of public water
systems.
State Grants for Underground Injection Control Programs. Section
1443(b)(5) authorizes $15 million/year to carry out their underground
injection control programs that regulate activities such as injection
of millions of gallons of hazardous waste underground.
National Assistance Program for Water Infrastructure and
Watersheds. The 1996 Amendments unconditionally authorized $25 million/
year (and authorized another $25 million/year in any fiscal year for
which the State Revolving Fund is 75% funded) for grants to states to
provide technical and financial assistance for the construction,
rehabilitation, and improvement of public water systems and for source
water protection programs, in SDWA 1441.
Records, Inspections, and Monitoring. The SDWA also authorizes $10
million/year for monitoring for levels of unregulated contaminants in
drinking water, in 1445(a)(2).
Source Water Petition Program. Section 1454 authorizes $5 million/
year for grants to states to carry out programs under which water
systems or municipalities may submit a petition to get funding for
source water protection programs.
Drinking Water Studies. Section 1458 authorizes $12.5 million/year
for studies of waterborne disease, health effects of contaminants on
pregnant women, infants, children, the elderly, and other vulnerable
populations, and other important issues regarding the potential impacts
of drinking water contaminants on public health.
Thus, it is clear that there are many important drinking water
programs whose authorizations have expired, and that deserve
Congressional review and reauthorization.
IV. AFFORDABILITY CAN BE ACHIEVED THROUGH INNOVATIVE SOLUTIONS THAT
PRESERVE EQUAL ACCESS TO SAFE DRINKING WATER.
NRDC strongly believes that all Americans deserve water that is
safe to drink and affordable. NRDC recognizes the special challenges
faced by small water systems and believes that the best approach to
dealing with small system affordability issues is to encourage
cooperative strategies, innovative small system package treatment and
source protection, and targeted public funding. A blanket exemption for
certain contaminants for small systems is not a viable approach, and
would inappropriately create a ``second tier'' of lower quality tap
water for the users of small systems.
In many areas of the country, cooperative strategies such as
regionalization and consolidation would substantially help resolve
affordability concerns by achieving greater economies of scale and
making the provision of drinking water more efficient. To promote
drinking water affordability, we also endorse a program that would help
low-income consumers pay for their water bills--a Low Income Water
Assistance Program (``LIWAP'')--similar to the existing Low Income
Heating and Energy Assistance Program (``LIHEAP''). Furthermore, NRDC
endorses increasing funding for the Drinking Water State Revolving Fund
(``DWSRF''), with special consideration given to assisting small
systems.
EPA convened a National Drinking Water Advisory Council (``NDWAC'')
Work Group on National Small Systems Affordability Criteria in 2002.
The Work Group was asked to provide advice to the NDWAC, which in turn
provided recommendations to EPA in a July 2003 report. In this report,
the NDWAC recommended that EPA rely on cooperative strategies, targeted
funding to disadvantaged communities, a LIWAP, and other methods to
address the affordability problem without creating a less-protected
class of drinking water consumers. NRDC supports the conclusions of the
NDWAC affordability report.
V. EPA'S FAILURE TO REGULATE PERCHLORATE THREATENS PUBLIC HEALTH.
Nearly eight years after the 1996 SDWA Amendments, EPA has failed
to set a single new drinking water standard, or even propose to start
adopting one, under SDWA section 1412. Yet a number of contaminants--
including perchlorate, for example--have now been detected at risky
levels in millions of Americans' tap water. Congress should direct EPA
to set an MCL for perchlorate.
Perchlorate is a widespread toxic chemical that is used in large
quantities in rocket fuel, as well as in explosives, road flares, and
fireworks. Perchlorate blocks iodine from entering the thyroid gland,
thereby interfering with normal thyroid hormone production. Because
normal levels of thyroid hormone are critical to the development of the
brain, perchlorate poses especially high risks to newborn babies and
fetuses, and to people who already have thyroid problems or iodine
deficiency, including 15 percent of U.S. women of childbearing age.
Scientific evidence shows that low-level perchlorate exposure causes
health risks. Studies dating back to 1952 show that perchlorate
disrupts the thyroid and can cause adverse health effects. Perchlorate
affects thyroid hormone levels at very low concentrations: in one
study, investigators could not rule out effects in rats at the
miniscule dose of 0.01 mg/kg/day.
Epidemiological studies show noteworthy effects in newborns exposed
to perchlorate in utero. In one study, California infants whose mothers
drank water contaminated with perchlorate at 1-2 parts per billion
showed altered levels of thyroid hormones. In a second study, conducted
by the Arizona Health Department, infants born in a city with low
levels of perchlorate contamination in the drinking water (below 10
parts per billion) showed significantly different thyroid hormone
levels than infants born in another Arizona city with no perchlorate
contamination.3 Both iodide deficiency and changes in
thyroid hormone levels can cause irreversible damage to infant and
fetal brains; even small changes in maternal thyroid hormone levels can
decrease IQ in the child.4

---------------------------------------------------------------------------
Perchlorate has been used in significant quantities in at least 49
states, and was released into the environment in at least 30 states. It
contaminates over 20 million Americans' drinking water--in, for
example, Los Angeles, San Diego, Phoenix, Las Vegas, and much of
Southern California--above EPA's draft safe level. It is thus an
extremely widespread and dangerous pollutant.
In addition to causing widespread tap water contamination,
perchlorate has found its way into the nation's food supply, and has
been detected in fruits, vegetables, fish, animal feed, and milk
(perchlorate has been reported in both human breast milk and in cows
milk). Lettuce has been shown to absorb and retain perchlorate
contained in irrigation water, and recent reports find that perchlorate
also accumulates in melons, blackberries, strawberries, cucumbers,
soybeans, and mustard greens in the same manner. It likely also
contaminates and accumulates in other crops for which no test results
have been conducted or made public.
A single facility in Henderson, Nevada has created an unprecedented
perchlorate contamination plume--polluting Lake Mead and the entire
Colorado River downstream of the Hoover Dam, as well as the drinking
water of at least 15 million people in Southern California, Nevada, and
Arizona. Despite years of cleanup efforts overseen by the State of
Nevada, 200 pounds of perchlorate per day continue to enter the
Colorado River from this site in Henderson, averaging 3 tons a month of
additional contamination. To NRDC's knowledge, this plume affects more
people than any other single drinking water contamination source in the
United States. A second, slightly smaller perchlorate plume has also
been found in Henderson; this one has not yet reached the Colorado
River, but soon will if aggressive cleanup efforts are not put in
place.
To date, the Environmental Protection Agency's response has been to
do little or nothing about the perchlorate contamination crisis. It has
spent 18 years evaluating and re-evaluating the health risks posed by
perchlorate-contaminated drinking water. In July 2003, EPA closed its
multi-year perchlorate review by refusing to establish an enforceable
drinking water standard for the chemical, saying more study is needed.
Also in 2003, EPA requested that the National Academy of Sciences (NAS)
review perchlorate's health effects. The NAS review panel included
several scientists who, as lobbyists or expert witnesses for the
defense industry, had clear financial conflicts of interest. So far in
the course of the NAS review, two panel members have been forced to
resign because of direct industry ties and financial conflicts of
interest. See Peter Waldman, Perchlorate Panel Member Resigns, Wall
Street Journal (June 11, 2004). However, at least one other panel
member with direct industry connections and a financial stake in the
perchlorate review has been allowed to remain on the panel.
Also last year, EPA management issued a gag order to agency staff
banning scientists from publicly discussing the risks posed by
perchlorate. The order came on the heels of the release of two
studies--one conducted by EPA--revealing perchlorate contamination in
lettuce grown with water from the Colorado River. In addition to
mismanaging the standard-setting process, the EPA has not made cleanup
or regulatory action on perchlorate a priority. Thus, plumes across the
country have languished for years without adequate attention.
EPA and the Department of Defense have stonewalled public efforts
to learn more about the scope of perchlorate contamination nationwide.
To get more information about the government's action (and inaction) on
perchlorate, NRDC filed several Freedom of Information Act requests
with government agencies for details on the extent of contamination,
health risks, and government coordination with defense industry
contractors. EPA and the Department of Defense refused to answer these
information requests for over a year, requiring NRDC to file a lawsuit
this spring to force a response. The agencies' refusal to release
information about perchlorate contamination deprives the public of
important information about a threat to public health.
CONCLUSION
Congress should carefully oversee EPA's implementation of its
drinking water responsibilities and insist on full and effective
enforcement of the Safe Drinking Water Act. EPA's inaction or delayed
action in response to lead, perchlorate, and other contaminants in
drinking water has exacerbated environmental health threats.
Furthermore, a comprehensive reauthorization of the SDWA is needed to
fund the heart of the statute's drinking water program--national
primary drinking water regulations--as well as every other important
component of the act. Finally, the nation's deteriorating drinking
water infrastructure has increased the challenge of providing safe and
affordable drinking water across the country and, in the case of lead
in D.C., has contributed to at least one public health crisis. The
significant, targeted expenditures and creative financing and
management proposals outlined above are necessary to start meeting some
of the mounting infrastructure needs.
APPENDIX A
LEAD COALITION'S RECOMMENDATIONS
Lead Emergency Action for the District (LEAD), a coalition of local
and national health, environmental, and other citizen organizations of
which NRDC is a member, recommended the following actions in February.
The EPA and WASA Consent Order of June 2004 does not satisfy any of
these recommendations.
1. The U.S. Environmental Protection Agency (EPA) has the
responsibility to immediately take enforcement action against
WASA to ensure our health is protected, and should initiate a
full criminal and civil enforcement investigation.
The EPA has primary responsibility for overseeing the safety of the
District's drinking water supply. Unlike its vigorous actions to
resolve microbiological threats a decade ago, the agency has shirked
its responsibility in response to the recent lead problem. The EPA
should immediately initiate an enforcement action under its emergency
order authority (which allows the EPA to enforce when there is an
imminent health threat, requiring no finding of a violation of law),
and should initiate a parallel criminal and civil enforcement
investigation. The EPA order should mandate several specific actions,
including enforceable deadlines for:
(a) Expedited, valid testing of all schools and day care centers, both
first draw and flush samples.
(b) Expanded testing of homes beyond those with lead service lines.
WASA should arrange free water lead tests for all D.C.
residents. (This is what the New York City Department of
Environmental Protection has been doing for more than 10
years.) Notice of these free lead tests should be drafted in
consultation with EPA and the public, and should note the
health implications of elevated lead levels in water and the
threat from lead paint in D.C.
(c) Reissued accurate, understandable notices to consumers of lead
levels, health risks, and options to avoid lead, by mail and
through broadcast media. WASA should be required to immediately
notify all D.C. households whether they are believed to have
lead service lines or not, what the risks are, and should
arrange for free lead testing of any tap water on request.
Notices similar to those recently sent to lead service line
customers should be sent to customers who are not believed to
have lead service lines noting that there still may be a risk
of lead contamination, and offering to arrange for free lead
testing.
(d) Professional installation and maintenance of certified filters for
homes with lead service lines or high lead levels in their
water, and that have young children, pregnant women, women who
expect they may become pregnant, and other high risk
individuals.
(e) An aggressive, honest, ongoing public education campaign developed
with public input. This should include several specific
requirements, such as:
i) WASA should send all D.C. residents a detailed city-wide map of
all areas with known or suspected lead service lines with
accompanying health and other explanations.
ii) WASA should disclose detected lead levels on the city-wide map,
and should provide real time monitoring results for lead
and all contaminants found in its water.
iii) WASA must notify any home with a lead service line that has
been found to have excessive lead in an appropriate water
test that it is eligible for free lead service line
replacement, and the schedule for replacement. The notice
should also note whether WASA is responsible for only part
of the service line replacement or full service line
replacement under D.C. law.
iv) EPA and WASA must issue notices that publicly recommend that
those pregnant women, or parents of young children, with
lead service lines or whose water lead levels are in excess
of EPA's Action Level (or some other reasonable safety
level), should obtain blood screening for lead for their
children. This is not an emergency that would require going
to the emergency room, but it is a matter of importance,
and blood tests for lead levels should be provided by the
D.C. Department of Health.
(f) A comprehensive third-party review of all available records and
archives to determine whether the D.C. materials survey
correctly identifies all locations where lead components were
used;
(g) An expedited third-party review of the Corps' corrosion control and
disinfection byproduct control strategy, with mandatory
implementation of solutions by specified dates certain; and
(h) A top-to-bottom third party expert review of WASA and the Corps'
water quality, source water, and overall performance, including
a detailed review of their implementation of past consultant
recommendations, Comprehensive Performance Evaluations, and
sanitary surveys, and recommendations for long-term compliance
with current and upcoming rules and water quality objectives.
The review should seek public input and should be published.
2. EPA should immediately take enforcement action against the Army
Corps of Engineers' Washington Aqueduct and order it to
aggressively treat the water to reduce lead leaching.
The EPA's 1991 lead and copper regulations require the Washington
Aqueduct to treat our water in order to reduce its corrosivity; less
corrosive water should mean less lead leaching from pipes. While the
Corps and WASA do have a corrosion control program (albeit one that
reportedly was reviewed by the EPA far later than envisioned by the
1991 rules), it is obvious that it must be critically examined and
improved. Recent changes in water treatment at the Washington Aqueduct
(apparently made after the corrosion control plan went into effect),
aimed at reducing disinfection byproducts, may have altered the
chemistry of the city's water. An urgent independent review of the
corrosion control plan is warranted, with EPA-ordered steps to
implement recommended actions. Deadlines should be established for
completion of the review and implementation of its recommendations, and
the results should be made public as soon as they are completed. When
WASA was constituted, it entered into a governance agreement with the
city of Falls Church and Arlington County over Washington Aqueduct,
with oversight over expenses and actions. WASA and other customers
should long ago have insisted upon improvements in the Washington
Aqueduct's corrosion control program.
3. WASA must re-conduct its testing of District school water to be sure
that all drinking water fountains and all faucets used for
consumption in District schools and day care centers are
tested--both first draw and flushed samples--within two weeks.
WASA's recent water test results were highly misleading because
more than 97 percent of the samples taken were from faucets and
fountains flushed for 10 minutes. Since no student flushes a fountain
for 10 minutes before taking a drink, flushing water for a test sample
would create misleading samples and test results. (Flushing often will
reduce or eliminate lead levels in large buildings.) Since infants and
young children are most vulnerable to lead poisoning, schools and day
care centers should be top priorities for testing.
4. EPA and Congress should help WASA and the D.C. government fund home
treatment units or bottled water for pregnant women and infants
under age 6 in households that have lead service lines or lead
in the drinking water at levels above the EPA action level.
There are likely thousands of pregnant women and young children
under the age of 6 who are drinking tap water that contains lead at
levels higher than 15 parts per billion, EPA's action level. These
people need a safe alternative water supply until the problem has been
resolved. The D.C. government, EPA and Congress should fund alternative
water supplies for high-risk water drinkers. Bottled water is not
necessarily any safer than tap water unless it is independently tested
and confirmed to be pure, and many filters are not independently
certified to remove the levels of lead found in many D.C. homes' water.
Therefore, EPA should assist residents by assuring that any alternative
water supply (such as bottled water) is indeed free of lead and other
harmful contaminants, or that a filter is independently certified (see
www.nsf.org) to take care of lead. It should be noted that NSF
certifies only that lead levels up to 150 ppb will be reduced to below
10 ppb; there is no guarantee for reducing levels above 150 ppb.
Finally, it is critical that WASA and other officials involved ensure
that there is a follow-up program for maintenance of filters, since
poorly maintained filters can fail to remove lead or even make
contamination worse.
5. WASA should expedite replacement of lead service lines, and the City
Council should review policies on replacement of the
homeowner's portion of the line.
Under EPA's lead and copper rule, WASA reportedly has begun to
implement its obligation to replace 7 percent of the District's lead
service lines (or to test and clear homes served by lead service lines
as containing less than 15 ppb lead in their water) each year. At this
pace it will take nearly 15 years--until about 2018--for WASA to
replace all the city's lead service lines. In the meantime, thousands
of pregnant women, infants and children could be consuming water with
excessive lead levels. We strongly urge that the lead service line
replacement program be aggressively expedited. A schedule should be
published, with objective criteria for which lines will be replaced
first (presumably based primarily upon replacement of those lines
posing the greatest public health risk first). Federal and city general
funds should be set aside for this program to augment promised rate
increases on our water bills. WASA customers should not foot the entire
bill, since the decisions to approve the use of lead service lines were
made with the explicit approval and oversight of federal officials who
were overseeing the construction of the city's water lines and supply.
There was a vigorous public debate about the safety of lead service
lines stretching back to the 1890s, yet federal officials who ran the
city supply decided to use lead lines. District officials also should
consider using the city's multimillion dollar rainy-day fund to help
pay for service line replacements.
In addition, the City Council should review WASA's and the city's
policy about lead service line replacement for the portions of the line
that are supposedly owned by homeowners. Evidence is mounting that
partial lead service line replacement often will not solve the problem,
and actually can make lead levels worse by shaking loose lead in the
pipes and causing galvanic corrosion that may exacerbate lead problems.
Under recent EPA rule changes, it is apparently up to the City
Council to determine how much of the service line should be replaced by
WASA. In 1991, EPA originally required full lead service line
replacement unless the water utility could prove that it did not
control part of the line, in which case it was to replace only that
portion that the utility controlled. After being sued successfully by a
water industry group, the EPA changed the rules to provide that it is
largely a question of local law what portion of the lead service line
is the responsibility of the water utility. We believe that it is only
fair that since many of the lead service lines were installed from the
1890s through the 1940s under the direction, approval and control of
the District and federal officials, those authorities should be
responsible for replacing them, not homeowners. The cost to homeowners
of their portion of lead service line replacement could be thousands of
dollars, but it is far more efficient and cost-effective to replace the
entire service line at once, rather than digging up yards twice. This
is a question that deserves a full public airing by the City Council.
6. The City Council should create a permanent citizen water board for
water to oversee WASA and the Washington Aqueduct, to address
longstanding problems with D.C.'s water supply.
In 1996, the Natural Resources Defense Council (NRDC), Clean Water
Action (CWA), and the DC Area Water Consumers Organized for Protection
(DC Water COPs) issued a report, based in large part on city and
federal records obtained under the Freedom of Information Act. That
report found serious ongoing problems with the District's water, and
identified likely problems that could occur in the future. Among the
current and future problems noted were lead contamination, bacteria and
parasites, cloudiness (turbidity) in the water--which may indicate poor
filtration and can interfere with disinfection--and disinfection
byproducts that cause cancer and may cause birth defects and
miscarriages. The report also noted that the Washington Aqueduct's
water treatment plants need a major infusion of funds to modernize and
upgrade treatment, and that the District has ancient and deteriorating
water pipes leading to water main breaks, regrowth of bacteria, and
lead problems. Those pipes must be replaced. In addition, the WASA-
operated sewage collection and treatment systems have serious
inadequacies, including major problems whenever stormwater runoff
overloads the treatment plant's capacity, causing raw sewage to flow
into the Anacostia and Potomac rivers.
In the wake of the D.C. citywide boil-water alerts in 1993 and 1996
due to turbidity and bacteria problems, and EPA's enforcement orders
issued thereafter, comprehensive sanitary surveys and engineering
reviews by outside contractors found a series of serious problems with
our water treatment and distribution system. These reviews recommended
hundreds of millions of dollars in improvements in the city's water
supply system.
While the city has addressed some of the most pressing problems, it
has not made many of the important investments needed to repair local
water infrastructure. We strongly recommend that the City Council
establish a citizen water board to oversee the city's water supply and
sewer system. The board should oversee not only steps to improve our
drinking water system, but also WASA's storm water and sewer
obligations, because of the overall competition for water
infrastructure dollars and need to focus on whole watershed and ``sewer
shed'' solutions. This board--like those created by some states to
oversee electric and other utilities--should be funded with a small
surcharge on water and sewer bills, and should be wholly independent of
WASA and the Washington Aqueduct. It should include independent
engineering and public health experts and citizen activists interested
in drinking water, and should issue an annual progress report on WASA's
and the Washington Aqueduct's performance, progress and problems.
7. The City Council must improve its oversight of WASA.
The District's City Council is responsible for overseeing WASA's
day-to-day activities, and has failed to do its job over recent years
to make sure that WASA is carrying out its responsibilities to deliver
safe drinking water and to safely collect and fully treat city sewage.
More aggressive City Council oversight is needed to avoid continued
problems with WASA.
8. The mayor should make tap water and all environmental protection a
high priority.
The mayor should make drinking water safety, sewage collection and
treatment and environmental protection a high priority. The mayor bears
some responsibility for ensuring that WASA is doing its job. He has
many ways to influence WASA's board and daily operations, and should
insist on regular briefings and updates on how the city is fulfilling
its obligations to provide these most basic city services.
9. Consumers, health, and citizens groups should be on the blue ribbon
commission, and should recommend people to serve on the panel.
The announced ``independent'' panel to review WASA's embarrassing
performance in addressing the lead problem has instead morphed into an
internal review panel of city officials, including two of the WASA
officials who so obviously have failed to do their jobs. In order to
avoid a panel that merely papers over the problems and whitewashes the
lead crisis, LEAD is calling upon city officials to name independent
experts, consumers, citizen groups and environmentalists to the panel.
10. The EPA, CDC, the D.C. Dept of Health and the City Council should
establish a joint task force with citizen participation, to
evaluate the extent of lead poisoning from all sources in the
District, and its environmental justice implications,
particularly for low-income African-American and Latino
households.
According to expert estimates, the District has widespread lead
poisoning, affecting perhaps tens of thousands of District children.
Because of the city's demographic and economic realities, most of these
children are African American and Latino. The District and federal
officials should establish a joint task force, with citizens and
medical experts, to evaluate the extent of the problem and its
environmental justice implications, and to recommend actions to remedy
it.

Mr. Gillmor. Thank you.
Our next witness is Donald Correll, who is the President
and the CEO of Pennichuck Corporation, and he is representing
the National Association of Water Companies. And he is
represented by one of our distinguished colleagues, Charlie
Bass.
Charlie, do you have anything----
Mr. Bass. If the chairman would be kind enough to yield
slightly out of order, I want to welcome you here. And I
apologize, I have an unbreakable commitment at noon. And so if
the chair would be so good as to allow me to invite Mr. Correll
to visit me later on after he has testified, I would love to
hear what he has to say.
I want to thank you for being here today. Pennichuck
Waterworks is a great constituent and provides water service
for the city of Nashua.
And I thank the chairman for yielding to me for that
comment.
Mr. Gillmor. Thank you, Mr. Bass.
Mr. Correll?
STATEMENT OF DONALD L. CORRELL
Mr. Correll. Thank you. Mr. Chairman, members of the
committee, thank you for the invitation to testify today before
your committee. My name is Don Correll, and I am President and
CEO of Pennichuck Corporation.
Pennichuck was founded in 1852 and has grown to become the
largest investor-owned water company in the State of New
Hampshire, serving a population of 120,000 people in 22
communities in southern New Hampshire and in Massachusetts.
Pennichuck is, in fact, the oldest, continuously operating
business in the State of New Hampshire.
I am testifying today on behalf of the National Association
of Water Companies. The NAWC is the only national organization
exclusively representing all aspects of private and investor-
owned water industry. The NAWC has more than 150 members, which
in turn own or operate thousands of utilities in 38 States
around the country.
I commend the subcommittee for tackling the complex issue
of drinking water safety, and specifically the lead problems we
have seen. Many of these issues are related to the broader
infrastructure problem this committee has been looking at for
quite some time, and let me start there and then I will talk
specifically about the lead.
Cities, towns, and utilities face a major challenge over
the next several decades replacing aging and worn-out drinking
water infrastructure. According to the EPA, utilities will
spend hundreds of billions of dollars over the next 2 decades
replacing the aging infrastructure. The Congressional Budget
Office and the GAO have done similar studies, and their cost
estimates are similar to the EPA's.
Utilities and localities must take the lead in addressing
this infrastructure challenge by assessing the many
organizational, managerial, and financial tools at their
disposal. Clearly, the Federal Government has a role in
assisting in this challenge, but that role should not be to
take on the major financial responsibility for infrastructure
replacement.
This would cause a drain on the U.S. Treasury for something
that should continue to be the responsibility of our industry,
municipalities, and our customers. Instead, the Federal
Government's role should be to encourage utilities to pursue
smart management practices that will lead utilities to
efficient operations, good service, and economic self-
sustainability.
These practices include utility consolidation, sound asset
management, public-private partnerships, and full cost of
service rates. In my written statements, I go into these four
areas in depth. However, due to our time constraints today, I
will only touch on two. However, I encourage the subcommittee
to keep in mind all of these practices when considering and
debating any infrastructure legislation down the road.
Let me talk first about asset management. Utilities manage
their infrastructure assets, such as pipelines and other
equipment, to maximize the useful life of the assets, increase
efficiency, minimize costs, and maintain service to customers.
Careful management of assets is essential if we are to
successfully meet the infrastructure financing challenge.
Successfully managing our system in Pennichuck, which now
amounts to over 500 miles of mains for a century and a half, I
can assure you that we have consistently applied sound
management practices in managing the assets of our company.
However, many localities do not have in place such asset
management plans. In fact, the GAO has estimated that as many
as 25 percent of all utilities do not have such a plan.
This is an area where there is much room for improvement,
and Congress should, therefore, encourage as part of the SRF
funding process the implementation of sound asset management
practices.
Another area I would like to spend a moment on is public-
private partnerships. Municipalities, large and small, all over
the country have realized great savings and success through
partnerships with private firms. These partnerships take many
forms, but can be broadly broken down into three categories--
privately owned utilities regulated by State and Federal
institutions, municipal utilities contracting out small
portions of their operations such as billing and meter reading,
and multi-year, all-inclusive management contracts wherein a
private firm runs and manages most or all of the aspects of a
municipally owned utility.
Cost savings that localities have realized over the years
from such arrangements range up to 40 percent, which could free
up much-needed capital for infrastructure replacement without
burdening either the customers or the American taxpayer.
Congress should encourage utilities to consider and pursue
these creative public-private partnerships.
Another role in the Federal Government--for the Federal
Government, and specifically for Congress, in passing
legislation to eliminate the State volume caps on private
activity bonds and water and wastewater--for water and
wastewater projects. While I know that is a change in the tax
code that is not under the jurisdiction of this committee, such
a change is perhaps the simplest and most effective way to
provide capital for infrastructure projects.
In fact, billions of investment dollars would be stimulated
by this tax change, but it will cost the Federal Government
less than $150 million over 10 years according to the Joint
Committee on Taxation.
Now, let me turn just for a moment on the lead issue. The
NAWC does not have all the details on what has transpired in
Washington. We do, however, believe that this is an important
issue, and that an independent study of the drinking water lead
contamination incidence should be undertaken to evaluate what,
if any, changes may need to be made in the law or regulation.
Based on recent U.S. EPA data, there is no reason at this
time to believe that there is a nationwide problem that would
require changes to the SDWA, and the NAWC believes that the
corrosion control under the lead and copper rule has been an
effective means of reducing exposure to drinking water.
The current requirements protect public health, and the
U.S. EPA is currently engaged in an extensive national review
of the lead and copper rule implementation to identify how well
the rule is performing across the Nation and what gaps exist in
Federal guidance and regulation. We should not consider
revising the lead and copper rule until at least that review is
completed.
We appreciate the leadership role that this subcommittee
has taken to address water infrastructure problems, and we also
appreciate the concern that you have expressed regarding the
need for cost effective solutions. And we look forward to
working with the committee to meet these challenges and to move
the industry to economic self-sufficiency.
Thank you.
[The prepared statement of Donald L. Correll follows:]
Prepared Statement of Donald L. Correll, President and CEO, Pennichuck
Corporation
Mr. Chairman and members of the subcommittee, thank you for the
invitation to testify before you today.
My name is Donald Correll. Since August of 2003 I have served as
President and CEO of Pennichuck Corporation. Pennichuck Water Works was
founded in 1852 and has grown to become the largest investor-owned
water company in the state of New Hampshire, serving a population of
120,000 people in 22 communities throughout southern New Hampshire and
in Massachusetts.
Pennichuck Corporation is a holding company with five wholly owned
operating subsidiaries. The Company is comprised of three private water
utilities, Pennichuck Water Works, Inc., Pittsfield Aqueduct Company
and Pennichuck East Utility that are regulated by the New Hampshire
Public Utilities Commission, and two non-regulated companies,
Pennichuck Water Service Company and The Southwood Corporation.
Pennichuck is the oldest continuously operated company in New
Hampshire.
Prior to joining Pennichuck, from 1990 to 2001, I served as
Chairman and CEO of United Water, one of the largest water service
companies in the United States with operations and investment in 19
states, Canada, Mexico and the UK. I also serve as an advisory director
with Underground Solutions Inc., a water technology and service
company, based in Sarver, Pennsylvania, which is involved in the water
infrastructure industry.
I am testifying today on behalf of The National Association of
Water Companies, NAWC is the only national organization exclusively
representing all aspects of the private and investor-owned water
industry. The range of our members' business includes ownership of
regulated drinking water and wastewater utilities and the many forms of
public-private partnerships and management contract arrangements. NAWC
has more than 150 members, which in turn own or operate thousands of
utilities in 38 States around the country.
ROLE OF THE PRIVATE SECTOR
The private sector has long played a vital role in the provision of
water in our nation, and stands ready to do much more. The privately
owned water utility business traces its roots back to before the very
existence of our nation. And today, one out of every six Americans
receive their drinking water service from a private water company.
However, outright private ownership is but one-model localities can
pursue as a means of addressing their infrastructure challenges.
Another large and growing option is some form of public-private
partnerships, including contract operations, wherein the municipality
retains ownership of the asset; in this case a water utility and its
infrastructure, but the management and operations of the facility are
contracted out to a private company.
Management contract or public-private partnership arrangements
between municipalities and private companies represent a newer model
(started in the 1970s), and have become hugely popular in a very short
period of time. Today, private firms operate more than 2,400 publicly
owned water and wastewater facilities for nearly 2,000 municipalities.
Such arrangements have proven to be very popular with municipalities
and enjoy a 90% contract renewal rate.
History has shown that the private sector can and does provide the
public with safe and efficient water service through market-based
solutions. The private water industry has been on the cutting edge of
technical innovation and research. Furthermore, in this time of
increased utility security awareness, the private sector has once again
been on the forefront of these initiatives, bringing to the industry
firsthand security experience derived from working in some of the
world's hot spots.
THE AGING INFRASTRUCTURE CHALLENGE AND SOLUTIONS
NAWC commends the Subcommittee for tackling the complex issue of
safe drinking water and specifically the lead problems we have seen.
Many of the issues are related to the broader infrastructure problem
this committee has been looking at for some time. Let me start there,
and then I will talk specifically about the lead issue.
It has been well established from a number of sources that cities,
towns and utilities face a major challenge over the next several
decades replacing aging and worn-out drinking water infrastructure.
According to the EPA infrastructure gap analysis, issued in 2002,
drinking water systems will spend between $154 and $446 billion through
2019. Wastewater systems will spend between $331 and $450 billion over
that same period. In addition to EPA, the Congressional Budget Office
and the General Accounting office have done studies on the country's
infrastructure challenge and their cost estimates are similar to EPA's.
Utilities and localities must take the lead in addressing this
infrastructure challenge by accessing the many organizational,
managerial and financial tools at their disposal. Clearly, the Federal
Government has a role in assisting with this challenge, but that role
does not need to be taking on the major financial responsibility for
infrastructure. Instead the role should be to encourage utilities to
pursue smart business-like management practices including improving
operating efficiencies to free up cash for infrastructure replacement,
charging what it costs to provide the service including capital
investments, selecting cost-effective infrastructure replacement
technologies, and implementing an infrastructure replacement program
that will assure the utility's viability.
Public-private partnerships can often provide a proven model for
accomplishing all of the above. Direct government loan assistance to
utilities is another government role, but, like the Drinking Water-SRF,
should be carefully managed and targeted only where and when necessary.
An inappropriate role of government would be to subsidize the water
industry indefinitely with a massive federal grant program, as some
have advocated.
Grants are a very inefficient method of providing assistance to
utilities. Grants send the wrong conservation signals and can result in
bad management practices,
The Construction Grants Program of the 1970s had many problems,
which could very likely be reborn if a similar program were
reconstituted. Those problems included procurement regulations that
discounted quality for the sake of lowest price, lack of reliable
capital replacement accounts to ensure that funds exist for future
replacement (such as today), and little local buy-in or ownership on
the part of grant recipients, which resulted in sometimes wildly
overbuilt systems and wasted tax dollars.
The best means for providing federal funds are the State Revolving
Loan Funds along with the use of creative and innovative solutions. We
can make considerable progress toward solving our infrastructure needs
by avoiding the mistakes of the past and securing our water
infrastructure for the future. I encourage Congress therefore to retain
the State Revolving Loan Funds as the primary conduit of assistance to
water utilities.
Congress should also ensure that Federal assistance is used to
encourage strong management practices by water utilities. This should
include full cost of service rates, asset management, consolidation and
support for public-private partnerships.
Full Cost of Service Rates
Across the country, many water utilities are charging customers
water rates that are misleading and do not cover the cost of providing
the service. This has resulted in a devaluation of water as resource,
which not only causes utilities to rely on federal subsidies for
investment in infrastructure replacement, but also sends the wrong
signals to consumers about the value of water and the need for
conservation.
In some cases the actual cost of providing water service is greater
than the rates charged by utilities. In fact, Dr. Janice Beecher of
Beecher Policy Research said before this Subcommittee in March of 2001
``. . . when municipalities provide electricity and natural gas
services, revenues exceed total capital and operating
expenditures. For water and sewer services . . . total
expenditures exceed revenues. The findings generally suggest
that municipal water customers do not cover expenditures
through rates and other user charges.''
Also, in a study on this issue released by the General Accounting
Office, they found the amount of funds obtained from user charges and
other local sources of revenue was less than the full cost of providing
service for over a quarter of drinking water utilities. Indeed many
municipalities pride themselves on their low rates, and publish their
comparative rates as being lower than other when in fact, they are not
charging the full cost of service.
This clearly demonstrates the need for full cost of service rates.
Utilities must be able to generate the revenue needed to cover costs
and invest in replacing aging infrastructure. This can only happen when
we are charging customers the true cost of the services provided.
However, NAWC recognizes that increasing rates will put low-income
families at risk of not being able to afford their water bills. To
address this, NAWC supports a federal water rate payer assistance
program modeled after the Low-Income Home Energy Assistance Program
(LIHEAP).
However, we do not believe that the increased rates will be an
overwhelming burden for most Americans. According to the Congressional
Budget Office, Americans currently pay roughly 0.5% of their total
household income for water and wastewater service. This is
significantly less than other utility costs, which range from 2% to 5%
of household income, and suggest room for increases.
Asset Management
Generally, privately owned and operated utilities manage their
infrastructure assets, such as pipelines and other equipment to
maximize the useful lives of the assets, increase efficiency, minimize
costs, and maintain service to customers. Careful management of assets
is essential if we are to successfully meet the infrastructure
financing challenge. However, many localities do not have in place such
asset management plans. In fact the General Accounting Office has
estimated that as many as 25% of all utilities do not have such a plan.
Since good management of assets can go along way toward avoiding an
infrastructure-financing gap as well as addressing the infrastructure
replacement challenge, NAWC believes utilities should adopt such
practices. Congress should therefore encourage, as part of the SRF
Funding process, the implementation of sound asset management
practices.
Consolidation
There are over 50,000 community water systems in the United States
today, many of which are very small. In many, but not all cases, the
financial challenges facing these utilities can be addressed by
improving their economies of scale through consolidation. By tying
consideration of SRF funding to consolidation, Congress will encourage
utilities to put aside parochial interests, expand their vision and
improve the service to customers. Over the last five years, Pennichuck
has consummated dozens of acquisitions of smaller systems, many of
which would not have financially viable over the long-term. It is
important to note, that consolidation does not work everywhere, and is
not the answer for all problems. However, it is clear that
consolidating ownership and/or management functions with other
facilities can streamline a utility and save money.
Public-Private Partnerships
Municipalities large and small all over the country have realized
great savings and success through partnerships with private firms.
These partnerships take many forms, from contracting out small portions
of a utility's operations such as billing or meter reading, to multi-
year all inclusive management contracts wherein a private firm runs and
manages all aspects of a municipally owned utility, to the transfer of
assets to a private company. Cost savings that localities have realized
over the years from such arrangements range up to 40%, freeing up much
needed capital for infrastructure replacement, without burdening either
the customer or the American taxpayer. Likewise these arrangements have
often allowed municipalities to avoid significant rate adjustments
while still meeting the higher EPA water quality standards.
Therefore Congress should, whenever appropriate, encourage the
development of such partnerships as a tool for addressing our
infrastructure replacement challenges.
Access to State Revolving Loan Funds for Private Water Companies
Access to the DW-SRF (and the Clean Water SRF for that matter)
should be based on need and need alone. The ownership of the utility
should not be a factor. After all, it's the taxpayers, all taxpayers,
not just those of municipal utilities that fund The SRFs.
When Congress established the DW-SRF in 1996 they knew that the
benefits of the SRF would flow to the customers of privately owned
utilities, not the owners or stockholders. And this is working well in
many states. NAWC has many examples of privately owned utilities
working with States, receiving SRF assistance and extending service to
underserved or badly served populations. These are some of the best
examples of public-private partnerships.
However, we regret to report that there are still ten States
(Alabama Arkansas, Colorado, Georgia, Kansas, Mississippi, North
Carolina, Oklahoma, Tennessee, Wyoming) that, despite Congress's clear
intent, do not allow private utilities access to the DW-SRF.
Incredibly, these States are still allowed to use private utilities in
their needs survey, and thus receive SRF capitalization grant funds
based on this private utility need, a need they have no intention of
meeting. NAWC believes that Congress should only allow EPA to provide
SRF allocation grants to the States for the needs the State is willing
to actually meet. If a State does not allow private utility access to
the DW-SRF, EPA should reduce their allocation grant accordingly.
Also, I must report that in some of the states that allow private
access to the SRF, there are often burdensome application requirements
and fees that, in some cases, municipal utilities don't face. Also in
some States, their priority lists clearly favor municipally owned
utilities, and the needy private utilities often receive little or no
funding.
These processes are not in line with Congressional intent when you
granted private utility access to the SRF. We hope to continue working
with you on these issues.
Private Activity Bonds
Another role that the federal government, and specifically Congress
can play is passing legislation to eliminate the state volume caps on
Private Activity Bonds (PABs) for water and wastewater projects, thus
providing billions of dollars in capital that can be used to invest in
water infrastructure replacement. Changing the tax code and exempting
water and sewage facilities from the state volume caps could be one of
the most productive incentives Congress can provide to stimulate
infrastructure investment and replacement. In fact, billions of
potential investment will be stimulated by the tax change but it will
cost the federal government less than $150 million over ten years,
according to the Joint Committee on Taxation.
I understand that this issue does not fall under the jurisdiction
of this Committee, however it is an important tool for addressing the
infrastructure challenge, and therefore, I wanted to bring it to your
attention.
LEAD AND DRINKING WATER
Lead is a naturally occurring metal that was used regularly in a
number of industrial capacities for most of the 20th Century. Lead was
used as a component of paint, piping (including water service lines),
solder, brass, and as a gasoline additive until the 1980's. According
to the U.S. Environmental Protection Agency (USEPA), lead paint and the
contaminated dust and soil it generates is the leading household source
of lead exposure today. Research has confirmed that lead is highly
toxic. Ingestion of lead can pose a serious health risk to humans,
especially children.
Lead contamination in drinking water almost always occurs after
water has left the treatment plant when it travels through piping and
plumbing containing lead. Water is naturally corrosive, and in some
cases will corrode the pipes and plumbing through which it passes,
picking up lead. This corrosion can occur in home fixtures as well.
To control the corrosion, and thus the lead in water, many public
water systems add a corrosion inhibitor such as zinc orthophosphate to
the water. While this is often effective as a means of corrosion
control, it does have a downside, which is increased phosphate content
in wastewater in that community.
NAWC has a number of recommendations to address the lead issue
before this Subcommittee. Our recommendations closely follow those of
the American Water Works Association, including the idea that EPA must
rethink the ``Silo'' approach to regulation. Today rules are generally
developed in isolation from one another, without consideration to the
potential interconnectivity one rule may have with another. The recent
experiences some communities have had with lead may be due to the
drawbacks of the silo approach. We believe a holistic approach to
drinking water regulation is needed that takes into account
simultaneous compliance with existing drinking water and environmental
regulations. In addition to this, NAWC recommends the following:
1. NATIONAL LEAD REDUCTION STRATEGY.
NAWC advocates a comprehensive approach to reducing lead
contamination from all sources. Congress should require a respected
body such as the Centers for Disease Control to complete a
comprehensive study of lead exposure from all sources, and to develop a
national strategy to reduce lead exposure from all significant sources.
Such research should include a determination of the contribution to
lead in drinking water from lead service lines, pipes inside the home,
and plumbing fixtures.
NAWC also strongly advocates a continuing public education program
concerning all sources and hazards of lead exposure and effective
protective measures. Public education is a key component of a lead
exposure reduction strategy. Water suppliers, working in cooperation
with local and state public health officials and others, can help
deliver the needed messages on the dangers of lead and the part
everyone has to play in reducing risks. Since most lead contamination
occurs inside the home from paint chips and dust or comes from home
plumbing, increased public awareness is especially important.
2. OPTIMIZATION OF CORROSION CONTROL.
NAWC advocates the treatment technique of optimizing corrosion
control as the best way of reducing exposure from lead in drinking
water. Determining the corrosivity of water is complex and depended on
several characteristics of the water. Lead contamination of drinking
water is primarily the result of lead in home plumbing and fixtures
beyond the control of a drinking water utility. The means available to
drinking water systems to mitigate the degradation of water passing
through pipes and fixtures in home plumbing is through implementation
or modification of the corrosion control process. This can be done by
adjusting the finished water's pH and alkalinity or by adding corrosion
inhibitors.
If source water were the only way lead could enter drinking water,
establishing a maximum contaminant level (MCL) for a utility to meet at
the plant or in the distribution system would be sufficient to protect
public health as it is for the majority of regulated contaminants. If
lead were to occur in source waters, it could be removed in the
treatment process. Public water systems are clearly responsible for and
can control water quality at treatment facilities. However, the major
source of lead in drinking water is not source water, it is lead from
plumbing systems and faucets in homes that are beyond the control of
drinking water utilities. The contribution of lead service lines to
lead contamination is uncertain.
Some have suggested establishing an MCL for lead at the end user's
tap. This would have the effect of holding water suppliers legally
responsible not only for lead sources that they cannot control but also
the mistakes, omissions, and even illegal activities of others. There
is still lead solder in home plumbing although it was banned in 1986.
Studies have shown that brass faucets holding lead free water for an
eight-hour period can leach lead into water at levels of 10 ppb and
higher. Grounding of electrical circuits in homes to water pipes and
galvanic action between two dissimilar metals may increase corrosion
that could cause lead to leach into the water. Customers who soften
their water or otherwise change its corrosivity can affect the lead
content of the water. These types of problems cannot be solved by an
MCL at the tap or in the public water system. Each of these by
themselves or in combination can cause lead to leach into drinking
water. The SDWA limits EPA authority to regulating public water
systems. A tap within a residence is not and should not be considered
to be part of a public water system.
The SDWA also specifically prohibits USEPA from imposing both an
MCL and a treatment technique for the same contaminant. Therefore NAWC
advocates a lead control strategy of optimizing corrosion control in
conjunction with public education and a lead service line replacement
program as the best method to protect public health.
3. REPLACEMENT OF LEAD SERVICE LINES.
NAWC advocates lead service line removal as a means of reducing
lead contamination in drinking water when the lead service line is
significantly contributing to lead contamination. However, lead service
line replacement is complicated by the ownership of the lines. In some
instances, the water utility owns the entire line. In others, the
property owner owns the entire service line. And in still other cases,
part of the lead service line is owned by the utility and part by the
property owner.
A public water system can only be held legally liable for replacing
the service line or part of the service line owned by the utility. A
public water system has no legal means to compel a property owner to
replace a lead service line or portion of a lead service line.
Requiring a water utility to remove privately owned lead service lines
raises constitutional legal issues with regard to private property and
eminent domain. All agree that partial replacement of a lead service
increases lead levels in water and should be avoided. Further, removing
a lead service line may not reduce lead contamination of drinking
water. Tests have revealed high lead levels in homes that have no lead
service line and low to no measurable lead contamination in homes with
lead service lines. Removing lead service lines alone is not the
complete solution to reducing lead exposure from drinking water.
Because of the costs involved and the likelihood there will be
little or no public health benefit in some cases, lead service removal
programs should focus on removing lead service lines owned by a utility
that are significantly contributing to lead contamination as a high
priority.
4. INDEPENDENT STUDY OF LEAD PROBLEMS AND LEGISLATIVE AND REGULATORY
CHANGES.
NAWC advocates an independent study of the drinking water lead
contamination incidents to evaluate what if any changes may need to be
made in the law or regulation. Based on recent USEPA data (http://
www.epa.gov/safewater/lcrmr/lead--data.html) there is no reason, at
this time, to believe that there is a nationwide problem that would
require changes to the SDWA. The current SDWA requirements protect
public health and USEPA currently is engaged in an extensive national
review of the Lead and Copper Rule implementation to identify how well
the rule is performing across the nation and what gaps exist in federal
guidance and regulation. The Lead and Copper Rule should not be revised
until this review is completed.
NAWC recommends that Congress direct an independent study of the
high lead levels in the District of Columbia water system be conducted.
This could be done very soon in an appropriations bill.
CONCLUSION
We appreciate the leadership role that this Subcommittee has taken
to address water infrastructure problems, and we also appreciate the
concern that you have expressed regarding the need for cost-effective
solutions. These are long-term challenges, and we look forward to
working with the Committee to achieve long-term solutions that will
allow the drinking water industry to stand on its own two feet.
Mr. Gillmor. Thank you very much, Mr. Correll.
We will have Mr. Lynn Stovall, who is General Manager of
the Greenville Water System, representing the American Water
Works Association.
STATEMENT OF LYNN STOVALL
Mr. Stovall. Thank you, Mr. Chairman. My name is Lynn
Stovall. I am the General Manager for the Greenville Water
System in Greenville, South Carolina, and the past President of
the American Water Works Association.
I am here today on behalf of AWWA. The association and its
more than 4,700 utility members commend you for holding this
hearing to address lead contamination in drinking water
infrastructure and other challenges facing community drinking
water systems and their customers.
In our written statement, we summarized our views on lead
in drinking water infrastructure. This morning I would like to
highlight a few of the recommendations in our written
statement.
With regard to lead in drinking water, we know that lead
can pose serious health risks, and that certain groups,
including children, are more susceptible than others to lead
contamination. Even though the Centers for Disease Control
reports that drinking water is a minor source of elevated blood
lead levels, drinking water utilities take the issue very
seriously.
Our recommendations, and the steps that we are taking as an
industry leader, are spelled out in my testimony. But they
include a recommendation for a nationwide lead education and
reduction effort that focuses on all sources of lead, not just
drinking water.
AWWA cannot speak to the specifics of the situation in
Washington, DC, as that matter is still under investigation. We
can say that the problem experienced in Washington, DC does not
appear to be widespread or nationwide in scope.
While it may be appropriate to strengthen the lead and
copper rule in certain respects, based on lessons learned in
Washington thus far, the current rule does protect health and
its basic structure, a treatment technique coupled with an
action level, represents the most appropriate way to address a
Federal standard for lead in drinking water. I would add that
EPA appears to be proceeding in an appropriate and measured
fashion on this issue at this time.
AWWA has a number of recommendations to address the lead
issue. First and most importantly, we advocate a comprehensive
nationwide approach to reducing lead contamination from all
sources. This should involve a program of research and public
education concerning the sources of lead, the dangers of lead
exposure, and protection against lead contamination from all
sources, such as paint, dust, drinking water, and others.
It is important that the program not be limited to drinking
water, since drinking water is not a major source of lead
exposure. We advocate the use of treatment techniques by all
utilities to control corrosion, to reduce exposure to lead in
drinking water.
We support replacement of lead service lines that
significantly contribute to high lead levels in the home. We
advocate a holistic approach to the development and
implementation of drinking water regulations to minimize the
extent to which regulations can interfere with each other. We
propose an independent study of the drinking water lead
contamination incidence in Washington, DC to determine what
caused this incident and what lessons can be learned from it.
I would also like to briefly summarize our statement with
respect to infrastructure. The American Water Works Association
has long been committed to the proposition that utilities
should be self-sustaining through their rates and other local
charges, and we remain committed to that principle. Healthy
water systems will offer safe water at a cost that people are
willing to pay for, and will not rely on Federal support, at
least over the long term.
Having said that, we know that some water systems will
require assistance as they make the transition from the rates
they now charge that make the system locally sustainable. Some
communities face especially severe problems due to large
amounts of stranded assets resulting from significant
population declines in the service territory.
Federal requirements to remediate combined sewer overflows
and other Federal mandates also exacerbate funding problems in
many communities. AWWA has estimated that the Nation needs to
invest an additional $250 to $300 billion over the next 30
years in drinking water infrastructure beyond the current
levels of investment.
AWWA has a number of recommendations to begin addressing
this infrastructure gap. We believe there are roles for all
levels of government and for community water systems themselves
focusing on rates, asset management, and so forth.
With respect to the Federal Government, we recommend an
increase in support for meeting new standards, meeting homeland
security needs of community water systems, and replacing or
rehabilitating aging infrastructure. Assistance in the form of
very low or no interest loans with a 30- to 40-year repayment
period is an appropriate way to deliver such assistance.
Federal regulators, or States if they are administering the
assistance, should retain the authority they now have to make
loans or combinations of grants and loans and to use other
financing tools to leverage public and private capital.
Again, we thank you for holding this hearing this morning
on drinking water issues. AWWA stands ready to work with this
committee to develop responsible and fair solutions to the
challenges facing America's community water systems. I would be
pleased to answer any questions or provide additional material
to the committee.
[The prepared statement of Lynn Stovall follows:]
Prepared Statement of Lynn Stovall, General Manager, Greenville Water
System, Greenville, South Carolina on Behalf of the American Water
Works Association
INTRODUCTION
Good morning Mr. Chairman. I am Lynn Stovall, General Manager of
the Greenville Water System in Greenville, South Carolina. I am here
today on behalf of the American Water Works Association (AWWA). AWWA
appreciates the opportunity to present its views on drinking water
infrastructure needs and other salient issues.
AWWA was founded in 1881 and is the world's largest and oldest
scientific and educational association representing drinking water
supply professionals. The association's 57,000 members are comprised of
administrators, utility operators, professional engineers, contractors,
manufacturers, scientists, professors and health professionals. The
association's membership includes over 4,700 utilities that provide
over 80 percent of the nation's drinking water. AWWA and its members
are dedicated to providing safe, reliable drinking water to the
American people.
AWWA and its members commend you for holding this hearing to
address such important issues as lead and sustaining the nation's aging
water infrastructure. We believe few environmental activities are more
important to the health of this country than assuring the protection of
our water supplies and the treatment, distribution and consumption of a
safe, healthful and adequate supply of drinking water.
LEAD CONTAMINATION OF DRINKING WATER
Recently, there has been much interest in Congress about the
elevated levels of lead found in drinking water in Washington, DC. Much
of the discussion has centered on the lead service lines between the
distribution system and the home plumbing, and whether or not they are
a significant source of lead in drinking water. We cannot speak to the
specifics of the situation in Washington, DC. The matter is still under
investigation and AWWA has no direct knowledge of the cause of the
elevated lead levels found in tests of drinking water in Washington,
DC, or any remedial action that has been taken or should be taken in
that instance. Nor does AWWA have any information that would suggest
that the problem experienced in Washington, DC, is occurring in other
public water systems across the country. We can, however, provide
general information concerning the sources of lead in drinking water
and what has been done and can be done to reduce exposure to lead in
drinking water.
AWWA and its members emphatically support lead exposure reduction
measures that promote public health. We have a long history of
promoting measures and research to eliminate or reduce exposure to lead
through drinking water. AWWA supported amendments to the SDWA to
eliminate lead contamination in school drinking water and prohibit
drinking water coolers that were not lead free. Through the AWWA
Research Foundation (AwwaRF), public water supplies have spent
approximately $3.4 million dollars on research projects related to lead
and copper corrosion. AwwaRF plans to spend over $2.5 million more on
additional research. A summary of the funding for AwwaRF projects
related to the Lead and Copper Rule is attached to this statement.
BACKGROUND ON LEAD CONTAMINATION OF DRINKING WATER
Lead is a naturally occurring metal that was used regularly in a
number of industrial capacities for most of the 20th century. Lead was
used as a component of paint, piping (including water service lines),
solder, brass, and as a gasoline additive until the 1980's. According
to the U.S. Environmental Protection Agency (USEPA), lead paint and the
contaminated dust and soil it generates is the leading household source
of lead exposure. Research has confirmed that lead is highly toxic.
Ingestion of lead can pose a serious health risk to humans, especially
children. Health risks linked to lead ingestion include increased blood
pressure, reduced I.Q. levels, brain damage, loss of hearing, stunted
physical growth, reduced learning power, premature births, low birth-
weight, fertility problems, and miscarriages. Since 1974, average lead
concentration in human blood has been reduced almost 75 percent,
primarily as the result of removal of lead from gasoline and lead
solder from cans.
Lead contamination almost always occurs after water has left the
treatment plant when it travels through piping and plumbing containing
lead. Water is naturally corrosive, and in some cases will corrode the
pipes and plumbing through which it passes. This corrosion can occur in
home fixtures as well. If these fixtures are made of materials, like
brass, which contain lead, the fixtures can add dissolved lead to the
drinking water. Brass fixtures and lead-based solder used in household
plumbing prior to 1986 are significant sources of lead exposure in
drinking water. Grounding of electrical circuits in homes to water
pipes and galvanic action between two dissimilar metals may increase
corrosion that could cause lead to leach into the water. Customers who
soften their water or otherwise change its corrosivity can affect the
lead content of the water.
In 1986, Congress passed amendments to the Safe Drinking Water Act,
effectively banning the continued use of lead in materials used in
drinking water systems. This legislation prohibited the use of pipe,
solder or flux containing lead and required specific public
notification about the presence of lead in its drinking water or
drinking water system.
In 1991, USEPA published the Lead and Copper Rule (LCR), to require
water utilities to reduce and maintain the corrosivity of water in
order to minimize the leaching of lead from pipes and plumbing into
drinking water. The LCR requires public water systems to monitor first
flush lead levels in a predetermined number of homes based on system
size. The homes where monitoring is to occur are selected based on the
high likelihood that they will have lead service lines or plumbing that
contains solder with high concentrations of lead. Based on data from
this monitoring pool of homes, a public water system must meet a 15
parts per billion (ppb) action level at the 90th percentile for taps
monitored. Based on the initial monitoring and analysis under the
revised LCR, public water systems determined the needed process to
maintain ``optimal corrosion control.'' The primacy agency reviewed and
approved the proposed control strategies and must approve subsequent
changes.
If a public water system exceeds the 15ppb action level, it is
required to develop and undertake a lead service line replacement
program. The LCR requires that a system replace 7 percent of the lead
service lines which the system owns each year until all such lines have
been replaced, or until tap water monitoring indicates that its 90th
percentile lead level is equal to or less than 15ppb action level.
As part of a corrosion control strategy, many public water systems
add a corrosion inhibitor such as zinc orthophosphate to the water.
While this is often effective as a means of corrosion control, it does
increase the phosphate content in wastewater in that community.
Phosphate is a limiting nutrient in many surface waters to which
wastewater is discharged and is regulated under the Clean Water Act
because of its high potential to contribute to the eutrophication of
our lakes and rivers.
AWWA RECOMMENDATIONS ON LEAD
While some improvements to the Lead and Copper Rule may be possible
and may prove to be warranted, the basic structure of the rule--a
treatment technique and an action level--is sound. And we believe that
EPA is responding in an appropriate manner to the lead issues that have
been raised in Washington, D.C. In addition, AWWA advocates the
following measures to help reduce lead exposure from drinking water:
6. NATIONAL LEAD REDUCTION STRATEGY: First and most importantly, we
advocate a comprehensive national approach to reducing lead
contamination from all sources. This should involve a program
of research and public education concerning the sources of,
dangers of, and protection against lead contamination from all
sources such as paint, dust, drinking water, and others. It is
important that the program not be limited to drinking water,
since drinking water is not the major source of lead exposure.
7. OPTIMIZATION OF CORROSION CONTROL: We advocate the use of corrosion
control treatment techniques by all utilities to reduce
exposure to lead in drinking water.
8. REPLACEMENT OF LEAD SERVICE LINES: We support replacement of lead
service lines that significantly contribute to high lead levels
in the home.
9. HOLISTIC APPROACH TO DRINKING WATER REGULATIONS: We advocate a
``holistic'' approach to the development and implementation of
drinking water regulations to minimize the extent to which
regulations can interfere with each other.
10. INDEPENDENT STUDY OF D.C. LEAD PROBLEMS AND LEGISLATIVE AND
REGULATORY CHANGES: We propose an independent study of the
drinking water lead contamination incident in Washington, DC,
by a group such as the National Academy of Engineering, to
determine what caused this incident and what lessons may be
learned from this.
1. NATIONAL LEAD REDUCTION STRATEGY.
AWWA advocates a comprehensive approach to reducing lead
contamination from all sources. We believe that Congress should require
a respected body such as the Centers for Disease Control to complete a
comprehensive study of lead exposure from all sources, and to develop a
national strategy to reduce lead exposure from all significant sources.
Such research should include a determination of the contribution to
lead in drinking water from lead service lines, pipes inside the home,
and plumbing fixtures.
In addition, AWWA proposes a priority national public education
campaign aimed at measures and steps people can take to protect
themselves from significant sources of lead contamination. AWWA
believes that a national coordinated campaign involving all concerned
federal agencies and state and local governments will provide
significant public health benefits.
AWWA also strongly advocates a continuing public education program
concerning all sources of lead exposure and effective protective
measures. Public education is a key component of a lead exposure
reduction strategy. Water suppliers, working in cooperation with local
and state public health officials and others, can help deliver the
needed messages on the dangers of lead and the part everyone has to
play in reducing risks. Since most lead contamination occurs inside the
home from paint chips and dust or comes from home plumbing, increased
public awareness is especially important.
In the mid-1980's, AWWA launched the ``Get the Lead Out'' campaign
to raise the level of lead contamination awareness among consumers. We
created informational material for utilities to give their customers.
We now have consumer information about lead contamination in drinking
water on the AWWA website. Concerned consumers can take several
precautionary steps to limit possible exposure to lead from their home
plumbing. Flushing the tap if a faucet has gone unused for more than a
few hours and not using water from the hot water tap for cooking or
drinking are simple methods to avoid high lead levels. The longer water
stands in a faucet, the more lead can be dissolved and hot water
dissolves lead at a faster rate than cold water. AWWA recommends that
concerned consumers have their water tested by a State-certified
laboratory to determine if lead is leaching into their drinking water
from their home plumbing. Consumers should be advised of these
precautions even if the water system results from lead testing do not
exceed the USEPA ``action level'' of 15 ppb in more than ten percent of
homes tested. Although it is not a specific requirement in the LCR, a
water utility should notify a customer of the results of lead testing
of the consumer's tap.
2. OPTIMIZATION OF CORROSION CONTROL.
AWWA advocates the treatment technique of optimizing corrosion
control as the best way of reducing exposure from lead in drinking
water. Determining the corrosivity of water is complex and dependent on
several characteristics of the water. Lead contamination of drinking
water is primarily the result of lead in home plumbing and fixtures
beyond the control of a drinking water utility. The means available to
drinking water systems to mitigate the degradation of water passing
through pipes and fixtures in home plumbing is through implementation
or modification of the corrosion control process. This can be done by
adjusting the finished water's pH and alkalinity or by adding corrosion
inhibitors.
If source water were the only way lead could enter drinking water,
establishing a maximum contaminant level (MCL) for a utility to meet at
the plant or in the distribution system would be sufficient to protect
public health as it is for the majority of regulated contaminants. If
lead were to occur in source waters, it could be removed in the
treatment process. Public water systems are clearly responsible for and
can control water quality at treatment facilities. However, the major
source of lead in drinking water is not source water. It is lead from
plumbing systems and faucets in homes that are beyond the control of
drinking water utilities. The contribution of lead service lines to
lead contamination is uncertain.
Some have suggested establishing an MCL for lead at the end user's
tap. This would have the effect of holding water suppliers legally
responsible not only for lead sources that they cannot control but also
the mistakes, omissions, and even illegal activities of others. There
is still lead solder in home plumbing although it was banned in 1986.
Studies have shown that brass faucets holding lead free water for an
eight-hour period can leach lead into water at levels of 10 ppb and
higher. Grounding of electrical circuits in homes to water pipes and
galvanic action between two dissimilar metals may increase corrosion
that could cause lead to leach into the water. Customers who soften
their water or otherwise change its corrosivity can affect the lead
content of the water. These types of problems cannot be solved by an
MCL at the tap or in the public water system. Each of these by
themselves or in combination can cause lead to leach into drinking
water. The SDWA limits EPA authority to regulating public water
systems. A tap within a residence is not and should not be considered
to be part of a public water system.
The SDWA also specifically prohibits USEPA from imposing both an
MCL and a treatment technique for the same contaminant. Therefore, AWWA
advocates a lead control strategy of optimizing corrosion control in
conjunction with public education and a lead service line replacement
program as the best method to protect public health.
3. REPLACEMENT OF LEAD SERVICE LINES.
AWWA advocates lead service line removal as a means of reducing
lead contamination in drinking water when the lead service line is
significantly contributing to lead contamination. However, lead service
line replacement is complicated by the ownership of the lead service
lines. In some instances, the water utility owns the entire line. In
others, the property owner owns the entire service line. And in still
other cases, part of the lead service line is owned by the utility and
part by the property owner. A public water system can only be held
legally liable for replacing the service line or part of the service
line owned by the utility. A public water system has no legal means to
compel a property owner to replace a lead service line or portion of a
lead service line. Requiring a water utility to remove privately owned
lead service lines raises constitutional legal issues with regard to
private property and eminent domain. All agree that partial replacement
of a lead service increases lead levels in water and should be avoided.
Further, removing a lead service line may not reduce lead contamination
of drinking water. Tests have revealed high lead levels in homes that
have no lead service line and low to no measurable lead contamination
in homes with lead service lines. Removing lead service lines alone is
not the complete solution to reducing lead exposure from drinking
water. Because of the costs involved and the likelihood there will be
little or no public health benefit in some cases, lead service removal
programs should focus on removing lead service lines owned by a utility
that are significantly contributing to lead contamination as a high
priority.
When the LCR was promulgated in 1991, USEPA estimated that it would
cost $1.5-6.25 billion nationally ($2.1-$8.65 billion in 2003 dollars)
to remove lead service lines. The LCR estimate is for replacement that
will occur as a result of the rule. The USEPA estimate is based on the
assumption that 8,300 of the 15,000 systems with lead service lines
will be required to replace some lead service lines at a per service
line costs of $900-$1,800. A later study conducted by the AWWA Research
Foundation in 1994 estimated that there were a total of some 2.3 to 5.1
million lead service lines in the nation. Removal of the utility owned
portion of the lead service line would cost $3.4 to $5.1 billion
nationally ($4.2-$6.3 billion in 2003 dollars). Replacement of all lead
service lines, including the portions owned by property owners and by
utilities, would cost approximately $10-$14.1 billion nationally
($12.3-$17.5 in 2003 dollars).
Some property owners may be unable to afford the cost and local or
state restrictions may prevent a public water system from paying for or
financing the lead service line removal. A public water system has
access to the Drinking Water State Revolving Fund (DWSRF) to fund
removing lead service lines that it owns. A property owner may not have
such easy access to fund lead service line replacement. In 1991, AWWA
recommended in testimony that Congress consider enacting a tax credit
for property owners who must pay for the removal of lead service lines.
We still believe this is a good idea that is in the interests of public
health in this country.
The cost to consumers of removing lead service lines is in addition
to the cost of replacing aging drinking water infrastructure. These
many and expensive infrastructure costs to the consumer that we
discussed earlier in this testimony present a complicated challenge to
local governments in their efforts to remove lead service lines.
4. HOLISTIC APPROACH TO DRINKING WATER REGULATIONS.
AWWA advocates a holistic approach to drinking water regulations
that considers simultaneous compliance with existing drinking water
regulations and other environmental regulations. The recent experience
in Washington, DC, with lead contamination is one example of the
pitfalls of the ``silo'' approach to drinking water regulation. By
``silo'' we mean developing a rule in isolation and not completely
understanding its connectivity to other regulations. Without having all
of the data necessary for a complete technical analysis, it appears
that treatment changes (enhanced coagulation and switching to
chloramines) the utility instituted to comply with the Stage 1
Disinfectants and Disinfection By-Products Rule (DBPR) may have
contributed to the increased levels of lead in the district's drinking
water.
Potential problems with the Lead and Copper Rule (LCR) stemming
from treatment changes made to comply with the Stage 1 DBPR were known
at the time that regulation was finalized. In AWWA's comments on the
Notice of Data Availability (NODA) for the Stage 1 DBPR in 1998, and
again in our comments on the proposed LCR technical corrections in
1998, AWWA recommended that the enhanced coagulation requirements for
Stage 1 DBPR include greater flexibility for states and utilities in
determining the most appropriate treatment approach for simultaneous
control of organics, disinfection by-products, and corrosion.
USEPA expects to finalize the Long Term 2 Enhanced Surface Water
Treatment Rule (LT2ESWTR) and the Stage 2 Disinfectants and
Disinfection Byproducts Rule (DBPR) in early 2005. These rules specify
a range of treatment and management strategies to reduce disease
associated with Cryptosporidium and other pathogenic microorganisms
while at the same time avoiding dangerous levels of disinfectant
byproducts. Many more utilities will switch to chloramines or make
other major treatment changes to comply with the Stage 2 DBPR. The
effect of these rules on compliance with the LCR was not a
consideration in their development.
Furthermore, the recently released study by USEPA's Office of
Research and Development (ORD), The Occurrence of Disinfection By-
Products (DBPs) of Health Concern In Drinking Water: Results of a
Nationwide DBP Occurrence Study, found alternative treatment methods,
such as chloramine and ozone, create as many as 50 new, and possibly
more risky, DBPs. Little health effects information is available on
these new DBPS. In both Stage 1 DBPR and Stage 2 DBPR, there has been a
consistent and progressive shift to alternative disinfectants for
compliance. Unfortunately, this new research now suggests that there
may well be significant, and as yet unquantified, undesirable health
risks associated with this shift to alternative disinfectants.
The arsenic regulation provides another example of the ``silo''
approach to drinking water regulation. California has a more stringent
classification of hazardous waste than the rest of the nation. This
classification system was in place during the development of the
arsenic regulation. AWWA and many California utilities, in formal
comments on the proposed rule, advised USEPA that this regulation was
going to result in the production of tons of hazardous waste in
California. USEPA's approach to the hazardous waste issue was that this
classification system was California's problem and this issue didn't
need to be addressed in the national regulation. As a result, the costs
to dispose of the hazardous waste from the California utilities were
not included in the estimated national cost of compliance. Now, based
on the latest research, treatments to remove arsenic generate both
solid and liquid hazardous wastes, and the estimated costs to properly
dispose of these wastes from California utilities alone are equivalent
to EPA's estimated national cost of compliance.
Section 1412 (b)(5) of the SDWA states that rule writers must
consider risk tradeoffs in setting an MCL. In particular, they must
consider risk tradeoffs if the levels of other contaminants are raised
or they interfere with the efficacy of treatment techniques or
processes that are used to comply with other regulations. Consequently,
AWWA believes that the agency should adequately consider negative
consequences of regulatory actions, particularly with respect to
potential human health impacts. This issue is particularly acute when
regulations are driven by potential or poorly understood risks, such as
DBP regulations.
AWWA urges USEPA to appropriately consider simultaneous compliance
with existing drinking water regulations when a new drinking water
regulation is finalized. Additionally, USEPA should appropriately
account for the impacts from existing environmental regulations when it
finalizes a new national drinking water regulation. We believe that a
holistic approach to drinking water regulations will provide better
public health protection.
5. INDEPENDENT STUDY OF D.C. LEAD PROBLEMS AND LEGISLATIVE AND
REGULATORY CHANGES.
AWWA advocates an independent study of the drinking water lead
contamination incident in Washington, DC, to evaluate what if any
changes may need to be made in the law or regulation. Earlier this
year, Delegate Norton (DC) introduced H.R. 4268, the Lead-Free Drinking
Water Act of 2004. AWWA supports the purpose of the bill to improve
protection of public health by reducing exposure to lead contamination
in drinking water. However, AWWA believes that before legislation is
enacted, Congress needs to know for sure what caused the elevated lead
levels in the District of Columbia water system. At this time, it is
difficult to determine if H.R. 4268 could have prevented the current
high levels of lead in the District of Columbia water system. Solutions
proposed in the bill could be addressing issues that were not the cause
of the high lead levels and miss entirely the actual cause that needs
to be corrected. For instance, why were lead levels high in some homes
without lead service lines and low in some homes with lead service
lines? Why did the lead levels vary so widely for the same tap tested
at different intervals? This would lead one to believe that other
factors were the cause of or involved in the high lead levels. There is
no reason, at this time, to believe that the high lead level problem in
the District of Columbia is a nationwide problem that would require
changes to the SDWA. AWWA believes that the current SDWA requirements
protect public health and USEPA currently is engaged in an extensive
national review of the Lead and Copper Rule implementation to identify
how well the rule is performing across the nation and what gaps exist
in federal guidance and regulation. In May, USEPA convened a panel of
experts in St. Louis, Missouri, to address the issues involved in
complying with the Lead and Copper Rule and will publish the results.
AWWA supports these efforts by USEPA. The Lead and Copper Rule should
not be revised until this review is completed.
Many of the reforms suggested in H.R. 4268 can be accomplished in
the regulatory process rather than by statute. AWWA has concerns about
mandating scientific and technological regulatory procedures in
legislation. Scientific knowledge and technology change--sometimes very
rapidly. When these become embedded in statute, advances in scientific
knowledge become very difficult to address. The Lead and Copper Rule is
not perfect, and AWWA can support changes to make it a better and more
effective regulation in some areas. However, we recommend that the
regulatory changes proposed in H.R. 4268 be addressed in the regulatory
process.
AWWA recommends that Congress direct an independent study of the
high lead levels in the District of Columbia water system be conducted.
This could be done very soon in an appropriations bill.
AWWA Leadership on Lead
AWWA's leadership in reducing lead exposure through drinking water
continues to the present. In June of this year, AWWA adopted an action
plan to address lead contamination in drinking water. Our plan includes
the following activities:
A. Developing and distributing a framework for utilities:
Addressing simultaneous compliance with the Lead and Copper rule
(LCR) and other rules; and
Evaluating possible changes to optimized corrosion control, such
as introduction of an alternative corrosion inhibitor.
B. Developing and distributing information to utilities on ways to
encourage customers in lead service line replacement;
C. Developing and distributing information to assist utilities in
providing useful information to customers about lead and the
LCR;
D. Developing and distributing information to utilities on how to
assist schools and daycare centers evaluate and address high
lead levels in their facilities;
We believe that the results of this action plan will be of great
benefit to public health in the United States and will be of assistance
to EPA in making any needed improvements to the LCR.
SUSTAINING OUR AGING DRINKING WATER INFRASTRUCTURE
Another critical issue facing community water systems involves
sustaining the nation's aging drinking water infrastructure. In
previous testimony in Congress and in our report entitled Dawn of the
Replacement Era: Reinvesting in Drinking Water Infrastructure,
published in May 2001, AWWA called for a new partnership for investing
in drinking water infrastructure. AWWA recommended changing and
expanding the existing Drinking Water State Revolving Fund to
significantly increase federal funding for projects to repair, replace,
or rehabilitate drinking water infrastructure to include the aging
distribution system.
The events of September 11, 2001, have added a new dimension to the
protection of drinking water and infrastructure needs. Public water
systems now face significant costs to increase the security of the
nation's community water systems. AWWA estimates that drinking water
utilities need to spend approximately $1.6 billion immediately to
protect water systems' critical assets with improved perimeter security
and access controls. This does not include the capital costs of
upgrades to address vulnerabilities identified in vulnerability
assessments such as hardening pumping stations, chemical storage
buildings, transmission mains, adding redundant infrastructure, or
relocating facilities and pipelines.
A safe and secure drinking water infrastructure is one resource
that all Americans rely on every day. It is a cornerstone of both our
economic well-being and our public health. Largely buried underground
and invisible, it is also a resource many have taken for granted.
FEDERAL MANDATES AND THE CONTEXT FOR DRINKING WATER AND WASTEWATER
INFRASTRUCTURE FUNDING ISSUES
Both drinking water and wastewater utilities face enormously
expensive federal mandates that set the context for all other funding
issues. The drinking water community faces a complex array of expensive
new federal requirements and new standards, including standards for
arsenic, radon, disinfection byproducts, enhanced surface water
treatment, and others. Wastewater utilities also face enormously
expensive federal mandates, such as those relating to Combined Sewer
Overflows (CSO) and Sanitary Sewer Overflows (SSO).
For both water and wastewater utilities, these needs significantly
skew financing for other investments, including the replacement of
aging pipes, appurtenances, and other infrastructure. Many local
ratepayers may be seriously challenged to pay for these mandates, and
the full cost water service can cause lower-income customers to delay
or defer other spending. This in itself can cause serious health
effects if low-income customers defer or avoid visits to the doctor,
don't fill prescriptions, etc., in order to pay the water bill. In many
cases, it appears that spending for clean water mandates has ``driven
out'' a community's ability to raise rates for drinking water needs.
Because federal mandates have consumed the ratepayer's budget, more
routine repair and replacement of drinking water infrastructure has
been deferred in many cases.
We believe that significant federal assistance, including grants,
is appropriate to help meet the cost of these very expensive federal
mandates on water and wastewater utilities. We would point out that, in
the case of CSO and SSO mandates, federal support for the cost of those
requirements is not only justified in the community receiving federal
support, it also lowers costs for drinking water utilities downstream
in the form of improved water quality. This is especially true in
critical source water protection areas.
DRINKING WATER INFRASTRUCTURE NEEDS
The American Water Works Association (AWWA) has long been committed
to the proposition that utilities should be self-sustaining through
rates and other local charges. We believe that a healthy utility will
be locally self-sustaining and not dependent on federal assistance.
Having said that, we also recognize that new security concerns,
combined with the cost of compliance with federally mandated
regulations and the aging of many water systems, drive the need to
greatly increase the level of investment in water-related
infrastructure. AWWA recognizes that there is a gap between current
investment and levels of investment that are required to sustain
adequate drinking water service over the long run. Research has shown
that this gap is real, and in the coming decades approaches $300
billion above and beyond what water utilities are already spending.
Moreover, this gap is growing. The gap does not apply to every utility
and does not affect all utilities in the same way. But many utilities
are affected, and the solution properly involves all levels of
government as well as utilities themselves.
Notwithstanding AWWA's commitment to full cost recovery through
rates, some water systems will require assistance to make the
transition from current levels of investment to full sustainability
through rates and other local charges. This need is especially great in
systems with large amounts of stranded assets resulting from
significant population declines in their service territories or large
federal mandates for investment to remediate combined sewer overflow
(CSO) problems.
The federal government should renew its commitment to significant
support for compliance with health-protective standards, security, and
the repair and replacement of aging drinking water infrastructure. AWWA
recommends that:
1. The United States provide assistance to community water systems in
the form of very low or no-interest loans with a 30-to-40 year
repayment period. The federal government, or the states if the
program is administered through them, should also retain
current authority to make grants and loans in combination and
to use other financing tools to leverage public and private
capital.
2. Congress clarify that projects to meet standards; to address
security needs; and to repair, replace, or rehabilitate
drinking water infrastructure are eligible for assistance.
3. All community water systems be eligible for assistance, regardless
of size or type of ownership.
4. Repayment terms and conditions be reasonable. They may include
demonstrations of system viability and ability to repay a loan.
5. The application process and other procedures for those wishing to
access these funds be streamlined and minimized.
6. There be a designated allocation in the program for large systems
similar to the one in current law for small systems (15
percent), unless there are insufficient projects to use
earmarked funds in a given year.
7. Funds be available and encouragement given for voluntary
consolidation among water systems where such consolidation is
practical and cost-effective.
8. At least $15 billion over the next five years be provided in federal
assistance to community water systems for the purposes
described above.
LEAKING PIPES
The way we manage our water resources to serve human needs has a
major impact on the quality of the natural environment and the costs
that ratepayers must bear. Water conservation is a major public policy
concern because of the significant environmental benefits and energy
and cost savings to be gained. Saving water is saving dollars. The
facilities that we have built to dam, divert, transport, pump and treat
water are among the largest infrastructure engineering projects on
earth and are a great part of the cost of drinking water. Aging
distribution systems can be a source of water loss that drives up the
cost of water. The cost of the lost water is reflected in the need
build more or larger treatments plants to produce more water, to pump
more water at increased energy costs and to build more storage capacity
for drinking water needs. Studies have shown that conserving water
through such things as replacing aging infrastructure with leaking
pipes can help delay the need for developing expensive new drinking
water supply and treatment facilities. An AWWA Research Foundation
report in 1994 conservatively estimated the cost of lost water alone to
be $2.8 billion per year nationally ($3.5 billion in 2003 dollars). A
1995 Western Canada Water and Wastewater Association report on leak
detection estimated that a water savings of 4 percent to 20 percent
could be achieved through the elimination leaks from the distribution
system. When the cost of lost water, energy costs and the cost of
avoiding new infrastructure are added together, the money invested in
replacing aging leaking infrastructure is a good return on investment
for the nation.
CONCLUSION
America needs a new partnership for reinvesting in drinking water
infrastructure. There are important roles at all levels of government.
To help reduce the burden on consumers, many water utilities have made
great strides in efficiencies, with some utilities achieving a 20-
percent savings, or more, in operations and maintenance. Water
utilities will continue to reduce costs, seek cost-effective financing,
and employ innovative management strategies. And AWWA does not expect
that federal funds will be available for 100 percent of the increase in
spending facing the nation's water utilities.
AWWA remains committed to the principle of full cost recovery
through rates. Regardless, there will remain communities that can't
make the transition to sustainability through local rates without
federal assistance. Due to needs for investment in health-protective
standards, security projects, repair and replacement of infrastructure,
and demographic changes, many utilities will be very hard pressed to
meet their capital needs without some form of federal assistance. Much
of our investment need is driven by federal mandates and new security
needs. The nation has already accepted the principle that the federal
government should help pay for what it requires other levels of
government to do. Over the next 20 years, it is clear that Safe
Drinking Water Act (SDWA) and Clean Water Act (CWA) compliance
requirements and infrastructure needs will compete for limited capital
resources. New security concerns, combined with the aging of many water
systems, plus the capital cost of compliance with federally mandated
regulations, such as lead service line replacement, drive the need to
greatly increase the level of investment in water-related
infrastructure now. Compliance, security and infrastructure needs under
the SDWA and CWA can no longer be approached as separate issues.
Solutions need to be developed in the context of the nation's total
drinking water and wastewater compliance, security and infrastructure
needs.
AWWA and its members thank you for holding this hearing concerning
the infrastructure needs of America's drinking water utilities and lead
contamination of drinking water. AWWA pledges to work with Congress to
develop a responsible and fair solution to the nation's growing
drinking water infrastructure security challenges and eliminating lead
contamination of drinking water. We thank you for your consideration of
our views.
This concludes the AWWA statement on drinking water infrastructure
needs and other salient issues. I would be pleased to answer any
questions or provide additional material for the subcommittee.
Mr. Gillmor. Thank you very much.
And we will now go to Dr. Bruce Lanphear of the Cincinnati
Children's Hospital Medical Center, and it is always nice to
see a Buckeye on the panel.
Doctor?
STATEMENT OF BRUCE P. LANPHEAR
Mr. Lanphear. Thank you, Mr. Chairman.
During the past 3 decades, the percent of children in the
United States who have blood lead levels in excess of 10
micrograms per deciliter has declined by over 80 percent due to
regulations phasing out leaded gasoline, lead solder in
plumbing, and banning leaded paint used in housing and other
products.
As a result of this decline, some have concluded that lead
is a problem of the past. But research that has been conducted
over the past decade has made it clear that lead toxicity
remains a major public health problem, and it is this I would
like to focus on for my testimony.
The current definition of lead toxicity, defined as a blood
level of 10 micrograms per deciliter or higher, was based on
numerous studies. It was estimated, for example, that an
increase in children's blood lead from 10 to 20 micrograms per
deciliter was associated with a 2.5 to 3-point decline in their
intellectual abilities.
Unfortunately, this action level is often misconstrued as
evidence that there are no adverse effects below 10 micrograms
per deciliter. In a recent study published last year in The New
England Journal of Medicine, we reported that an increase in
children's blood levels from less than one microgram per
deciliter up to 10 micrograms per deciliter--that is, an
increase entirely below the CDC's action level--was associated
with a 7.5 IQ point deficit in children.
These findings were confirmed in a pooled analysis
involving over 1,300 children from seven prospective studies
conducted across the world. In review of these data, the CDC
recently proclaimed, although in a loud whisper I would say,
that more likely than not there is no threshold for the adverse
consequences of childhood lead exposure. To put that in another
way, over 90 percent of children in the United States who are
adversely affected or harmed by lead exposure never meet or
exceed the CDC action level of 10 micrograms per deciliter.
This makes lowering lead in drinking water and other
sources extremely important. Yet for reasons that are unclear
and scientifically inaccurate, the CDC did not change the
action level, nor did they alter recommendations to protect
children from lead exposure, whatever the source.
Was this because it was not justified? Or was it because
the members of the CDC Lead Advisory Committee were handpicked
by the lead industry?
Young children, as we have heard, are especially vulnerable
to lead exposure. Children's blood lead levels rise rapidly
between 6 and 12 months of age due to the confluence of
mouthing behaviors and increasing mobility. Nevertheless, lead
is a systemic toxin that affects all ages.
For example, it has been estimated that survivors of
childhood lead poisoning were twice as likely to die from
cardiovascular disease as adults compared with the general
population. Childhood lead exposure is a risk factor for
delinquency and criminal behavior. Lead exposure during
pregnancy is a risk factor for miscarriage or spontaneous
abortion.
The cost of childhood lead poisoning is staggering. It has
been estimated that the cost is over $40 billion each year in
the United States. To protect children from lead toxicity, it
is essential to identify lead hazards before a child is unduly
exposed. The alternative--to wait until a child develops lead
poisoning--is no longer defensible. Lead standards for house
dust, paint, soil, and water are fundamental to prevent lead
poisoning, but they must be based on scientific evidence.
Today, most lead standards were driven by what was
believed--and I emphasize believed--to be feasible to achieve,
not what was proven, to protect children or pregnant women. For
example, in 2001, the U.S. EPA set the floor lead standard at
40 micrograms per square foot. Numerous studies have found that
over 15 percent of children at that level will develop a blood
lead level in excess of 10 micrograms per deciliter.
Thus, the EPA's lead standards do not adequately protect
children. Indeed, they provide an illusion of safety.
In 1991, in the lead and copper rule, the U.S. EPA
recognized that our water lead standard may not adequately
protect pregnant women and children.
It is increasingly important to shift our efforts toward
the prevention of childhood lead toxicity by eliminating
environmental exposures to lead. To protect children and
pregnant women from the toxic effects of lead, we should set
standards for lead contaminant in house dust and water that are
proven to protect children.
We should conduct national, State, and community surveys to
identify and prioritize the elimination of lead hazards. For
communities that exceed a threshold of exposure, we should
require screening of housing units for lead hazards, including
lead and water, before children are unduly exposed. We should
mandate lead screening and housing after major renovation
projects or when water treatment processes are altered.
We should ban all non-essential uses of lead, including
water service valves, meters, and fittings. And, finally, we
need to improve communication. I don't mean to belittle the
problem of lead contamination in the DC water supply, but the
failed communication you have experienced is but the tip of the
iceberg. From my perspective, we can no longer trust the
scientific advisory committees of the U.S. EPA or the CDC.
These advisory committees have been contaminated by
industry, by the lead industry, to protect their own interests
at the expense of our children's health.
Thank you.
[The prepared statement of Bruce P. Lanphear follows:]
Prepared Statement of Bruce P. Lanphear, Cincinnati Children's Hospital
Medical Center
During the past three decades, the percent of U.S. children who
have blood lead levels > 10 mg/dL has declined by over 80% following
the elimination of leaded gasoline, lead solder used in plumbing and
canned foods, and leaded paint used in housing and other consumer
products. Lead is a confirmed toxin, but some have argued that lead
toxicity is a problem of the past. Research conducted over the past
decade has made it clear that lead toxicity remains a major public
health problem:
Despite the decline in children's blood lead levels, lead toxicity
remains epidemic among some children who live in older housing.
There is no discernible threshold for lead toxicity; indeed, lead-
associated deficits in children's intellectual function are
incrementally greater at blood lead < 10 mg/dL, the CDC action
level.
There is increasing data linking lead exposure with other diseases,
including delinquency, tooth decay and cardiovascular disease.
It is increasingly important to shift our efforts toward the
prevention of childhood lead toxicity by eliminating environmental
exposures to lead. To protect children and pregnant women from the
toxic effects of lead we should:
Promulgate scientifically-based standards for lead-contaminated house
dust and water. Existing EPA lead standards were based on what
was believed to be feasible to achieve; they are not adequate
to protect children.
Conduct national, state and community surveys of housing to identify
and prioritize the elimination of residential lead hazards.
Require screening of housing units for lead hazards (paint, dust,
soil and water) before children are unduly exposed, after lead
hazard controls or renovation in communities that exceed a
threshold of exposure.
Ban all non-essential uses of lead, including water service valves,
meters and fittings.
Sequela of Lead Poisoning
In the early 1900's, it was believed that if a child survived lead
poisoning, they would recover completely. Then, in 1943, Byers and Lord
reported that the effects of childhood lead poisoning were not limited
to symptoms associated with acute lead poisoning (1). Nineteen of 20
children who had ``recovered'' from lead poisoning failed high school
or had behavioral problems. In 1979, Needleman and his co-workers found
that children with higher tooth lead concentrations were more likely to
be rated unfavorably by teachers for distractibility, persistence in
work, organizational ability, dependence, impulsivity, daydreaming, and
ability to follow directions (2). In a follow-up study, they reported
that children in the higher tooth lead group were 6-times more likely
to have a reading disability and 7-times more likely to drop out of
school than those in the lower group (3).
Lead is a confirmed neurotoxin. Experimental studies, both in
rodents and non-human primates, have since documented lead-related
deficits at low-level lead exposure and established these to be direct
effects of lead (4-7). Moreover, the preponderance of epidemiologic
studies consistently shows persistent and deleterious effects of low-
level lead exposure on brain function (8-14). The current definition of
an elevated blood lead concentration of 10 mg/dL or higher, as defined
by the US Centers for Disease Control and the World Health
Organization, was based on adverse outcomes from numerous cross-
sectional and prospective studies (15, 16). It was estimated that there
is a 2.5 to 3 point IQ decrement linked with an increase in blood lead
from 10 mg/dL to 20 mg/dL (15, 16). The Centers for Disease Control
recognized that there was no discernable threshold for the adverse
effects of lead exposure, but set 10 mg/dL as an action level (16).
Unfortunately, this action level is often misconstrued as evidence that
there are no adverse effects below 10 mg/dL. Indeed, some pediatricians
consider blood lead concentrations below 10 mg/dL to be ``normal''. But
contemporary children have a body lead burden that is 10 to 100 times
higher than pre-industrial humans (17).
There is no evidence of a threshold for the adverse consequences of
childhood lead exposure. Schwartz reported that lead-associated
cognitive deficits and hearing loss occur at blood lead levels below 10
mg/dL (18, 19). In a meta-analysis, the observed decrement was greater
for studies with children having blood lead levels below 15 mg/dL
compared to those with children having higher blood lead levels (18).
In an analysis of NHANES III, the lead-associated reading deficit
increased, from ``1.0 point per 1 mg/dL increase in blood lead for the
entire sample to -1.7 point per 1 mg/dL increase for the subgroup with
blood lead levels below 5 mg/dL (20). In a prospective study, an
increase in lifetime mean blood lead level from < 1 to 10 mg/dL was
associated with a 7.4 point IQ deficit (21). Moreover, consistent with
the earlier studies, the lead-associated cognitive deficits associated
with each 1 mg/dL increase in blood lead level were greater at blood
lead concentrations below 10 mg/dL (18, 20-22). Although there are
several plausible mechanisms to explain these findings, the specific
mechanism is unclear (7).
Behavioral Problems
There is no ``behavioral signature'' of low-level lead toxicity,
but a consistent pattern of lead-induced abnormalities is emerging
(23). Antisocial, delinquent behavior during childhood and adolescence
is a product of many variables (24-25). But there is increasing
evidence that lead toxicity plays a role in its epigenesis (26-30). In
a cross-sectional study, Needleman and coworkers found that adolescents
with higher bone lead concentrations had higher scores for delinquent
and aggressive behaviors (29). In a prospective cohort study, Dietrich
and coworkers reported that higher blood lead levels in childhood were
associated with 4.5 more episodes of delinquent behaviors that posed a
risk for arrest in the prior 12 months compared with those who had the
lowest blood lead levels (30).
There is also evidence that lead is a reproductive toxin. In one
study, lead was associated with spontaneous abortion at blood lead
levels < 40 mg/dL, the level considered acceptable for an adult woman.
Compared with pregnant women whose blood lead concentration was < 5 mg/
dL, women who had blood lead levels between 10 mg/dL and 14 mg/dL were
at a 5-fold increased risk for spontaneous abortion (31). Women who had
blood lead levels > 15 mg/dL were at over 10-fold increased risk for
spontaneous abortion (31).
Developmental vulnerability
Young children and fetuses are especially vulnerable to the adverse
effects of some environmental neurotoxins (32). Critical processes
occur in the central nervous system during fetal development and early
childhood, including synaptogenesis, myelination and programmed
apoptosis (33). Some investigators found that blood lead in early
childhood were better predictors of cognitive deficits (9), whereas
others reported that blood lead levels in older childhood were better
predictors (8, 10, 21). Blood lead concentration in early childhood
tracks closely with subsequent blood lead levels (8, 10, 21). Thus, the
larger effects observed in older children may be due to chronicity of
exposure (23). Although the question of whether children are more
vulnerable to the toxic effects of lead exposure during the first 2
years of life is unresolved, they do ingest more lead and may absorb it
more efficiently than older children and adults (34-35). Thus, efforts
to prevent lead toxicity must occur prior to birth (36).
Rationale for Shifting to Primary Prevention
Despite the dramatic decline in children's blood lead levels there
are substantial numbers of children in the US who are exposed to
unacceptably high levels lead contamination in their environments (37-
39). There is also considerable evidence that lead is a systemic toxin.
It has been estimated, for example, that for every 1 mg/dL decline in
the population mean blood lead level, there would be 635,000 fewer
persons with hypertension, 3200 fewer with myocardial infarctions, 1300
fewer strokes and 3300 fewer deaths annually in the United States (40).
Survivors of childhood lead poisoning were twice as likely to die from
cardiovascular disease compared with the general population (41).
Dental caries, linked with lead exposure in both experimental and
epidemiologic studies, was estimated to account for over 2.5 million
cases of tooth decay in U.S. children (42-43). Other major problems are
linked with lead exposure, including spontaneous abortions (44),
impaired motor development (45-46), and growth retardation (47).
Finally, investigators of a randomized, controlled trial of succimer
(DMSA) did not find any neurobehavioral benefit of chelation for
children who had blood lead levels between 20 mg/dL and 44 mg/dL (48).
Collectively, the results of these studies argue that our efforts to
prevent impairments associated with low-level lead exposure should
emphasize primary prevention, which contrasts with current practices
and policies that rely almost exclusively on secondary prevention
efforts.
The cost of childhood lead poisoning is staggering. Landrigan and
co-workers have estimated that the annual cost of lead poisoning among
US children is over $40 billion (49). This estimate does not include
recent findings indicating that the drop in IQ is greater for each 1
mg/dL increase in blood lead at levels below 10 mg/dL (20-22). Nor does
it include other anticipated benefits, such as reductions in
cardiovascular disease, stunted growth, tooth decay and delinquent
behaviors (29-30, 40-47).
Prevention of Lead Exposure
The steps to prevent childhood lead exposure are, in theory,
simple. The first step is to identify major sources of lead exposure.
Second, because lead is ubiquitous--it can be found in house dust and
residential soil throughout the country--it is necessary to identify
unacceptable or hazardous levels of lead in sources that children
encounter. The third step is to conduct screening to identify housing
or products that contain lead hazards. Screening children to identify
those with undue lead exposure is important, but it should be used as a
safety net, not the major prevention effort. The fourth step is to
develop and test interventions to reduce or eliminate lead exposures.
Finally, regulations and policies are needed to identify lead hazards
and implement the interventions.
Sources of Lead Exposure
Paint is the major source of childhood lead poisoning in the United
States. Paint that was used on both the interior and exterior of houses
through the 1950s, and continuing to some extent through the 1970s,
often contained high concentrations of lead (50). Children with blood
lead above 55 mg/dL were 10-times more likely to have paint chips
observable on abdominal radiographs than children who had blood lead
levels below this value (51). The majority of preschool children with
blood lead over 25 mg/dL were reported to put paint chips in their
mouth (52). Paint is also the major source for lead-contamination of
house dust, which is the major pathway for lead intake among children
(53-56).
Lead-contaminated soil is an important source of lead intake for
urban children. Soil ingestion, reported to occur in 26% urban children
(34), is a risk factor for higher blood lead concentration (55, 57).
Children living in former or active mining, milling and smelter
communities are at risk for lead exposure via lead-contaminated soil
(58-59). In a pooled analysis of 12 studies, there was an estimated 3.8
mg/dL increase in blood lead concentration for every 1000 ppm increase
in soil lead concentration (55). The variation in the reported
relationship of lead-contaminated soil is due to a number of factors,
including the age of children studied, adjustment for the contribution
of lead intake from other sources, and mouthing behaviors.
Lead in water is an important source of lead intake for children
and pregnant women. The EPA standard for lead in water is 15 mg/L (ppb)
in residential water and 20 ppb in public drinking fountains (60). In a
prospective study of 248 children followed from 6 to 24 months,
children who were exposed to water lead > 5 ppb had blood lead
concentrations 1.0 mg/dL higher than children with water lead levels <
5 ppb (34). In a study in Glasgow, tap water was the main source of
raised maternal blood lead concentrations, accounting for 76% of
maternal blood lead levels above 10 mg/dL (61). Intake of lead-
contaminated water is, by itself, unlikely to cause a child to have
blood lead levels > 10 mg/dL. Still, it is an important source of lead
intake for young children and pregnant women in many communities.
Indeed, as predicted, water is becoming an increasingly important
source of childhood lead exposure as other sources of lead intake
decline (62). Furthermore, because lead exposure is cumulative and
there is no apparent threshold for the adverse effects of lead
exposure, all sources of lead exposure must eventually be eliminated.
Ingestion and Absorption
There is large variation in the ingestion and absorption of lead
during the first two years of life. Children's blood lead levels rise
rapidly between 6 and 12 months of age, peak between 18 months to 36
months, then gradually decline (34, 63). The peak in children's blood
lead levels is due to the confluence of normal mouthing behaviors and
increasing mobility (34). Lead-contaminated water and floor dust is a
source of lead intake throughout early childhood, but lead-contaminated
dust on windowsills is not a major source of intake until the second
year of life, when children stand upright (34). Soil ingestion, as
reported by parents, peaks between 12 and 18 months and diminishes
thereafter (34). Younger children absorb lead more efficiently than
older children (35).
Residential Standards
Under section 403 of Title X, the U.S. Congress mandated the
Environmental Protection Agency (EPA) to promulgate health-based lead
standards. There are at least four reasons to develop residential lead
standards (36). First, residential standards are necessary to identify
lead hazards before a child is unduly exposed. The alternative, to wait
until a child is unduly exposed, is no longer defensible. Second, they
are critical for the management of children who are identified as
having undue lead exposure. If environmental testing is not done, the
major source(s) of environmental lead exposure may be overlooked. More
importantly, it is clear that attempts to reduce lead exposure can
actually result in increased contamination of a child's environment and
blood lead concentration. Clearance dust tests should therefore be
conducted after remodeling or renovation, abatement or a lead hazard
control to protect children. Finally, standards serve as a benchmark to
compare the effectiveness and duration of various lead hazard controls.
Unfortunately, if standards remain voluntary, they are unlikely to be
implemented and will not protect children from undue lead exposure.
Most lead standards were driven by what was believed to be feasible
to attain, not because they were shown to protect children. In 1976,
the CPSC set the residential paint lead concentration at .06% because
there was evidence that paint could be manufactured with this smaller
amount of contamination (64). Similarly, data used to estimate the safe
level of lead in water may not adequately protect pregnant women and
children (34, 60). In 1992, Congress mandated EPA to set health based
standards for residential lead hazards. The residential standards
promulgated by EPA (65) were, once again, based on what was believed to
be feasible to attain rather than scientific data shown to protect
children (36).
In 2001, the US EPA promulgated residential lead standards of 40
mg/ft\2\ for floors and 250 mg/ft\2\ for window sills (65). Data from
epidemiologic studies show that 5% of children have a blood lead level
10 mg/dL at a median floor dust lead level of 5 mg/ft\2\ (54-55). At
a floor standard of 50 mg/ft\2\, 20% of children were estimated to have
a blood lead level 10 mg/dL (55). Children who were exposed to floor
dust lead levels 25 mg/ft\2\ were at 8-times greater risk of having
blood lead levels 10 mg/dL compared with those exposed to levels
below 2.5 mg/ft\2\ (34). Thus, EPA's lead standard for floors do not
adequately protect children. Indeed, these standards dictate the levels
of lead-contamination considered ``normal'' or ``low'', and they
provide an illusion of safety.
Steps to Eliminate Subclinical Lead Toxicity
A comprehensive strategy for the primary prevention of childhood
lead poisoning should include several components.
1. Empirically-Based Lead Standards
The promulgation of health-based lead standards is essential. These
standards should be developed using epidemiologic data. These standards
must be required and enforced; ``voluntary'' standards will not protect
children from undue lead exposure.
2. Establish Screening Programs
Housing should be screened before a child is unduly exposed, after
lead hazard controls or renovation (36). Screening housing units by
using dust samples, visual inspection, and water sampling in select
communities should be incorporated into housing codes. Screening should
be required prior to approval of federal subsidies for housing in
communities that exceed a threshold determined to protect children and
pregnant women.
3. Trials to Prove Lead Hazard Controls Protect Children
Once residential lead hazards are identified, it is essential to
have safe and effective methods to eliminate them. Too often, we have
relied on expert opinion about what is safe or effective.
4. Strategy to Identify and Target Residential Lead Hazards
Conduct national, state and community surveys of housing need to
identify and prioritize the elimination of residential lead hazards.
There should be plans for the remediation of lead-contaminated housing
and replacement of leaded plumbing. Lead-safe work practices should be
adopted and taught to homeowners, contractors, painters and persons who
maintain housing.
5. Ban all non-essential uses of lead.
For far too long, we have allowed children to be exposed to lead.
While there has been some progress in reducing lead pollution from
leaded gasoline, lead-based paint and canned foods, children continue
to be unduly exposed to environmental lead. It is time to ban all non-
essential uses of lead, including water service valves, meters and
fittings.
Despite dramatic reductions in children's blood lead levels,
childhood lead exposure remains a major public health problem. As
foretold by Turner in 1908, educational efforts alone are inadequate to
prevent undue lead exposure in children (66). The current lead
poisoning prevention strategy largely ignores existing scientific
evidence indicating that our efforts should emphasize primary
prevention using environmental controls to make lead-contaminated
paint, soil and water inaccessible before a child is unduly exposed.
For too long, we have simply passed out brochures or instructed mothers
to ``clean their houses better'' to reduce their child's risk of lead
poisoning. For too long, we have relied on ``voluntary'' standards and
allowed lax enforcement of existing standards. Most federal agencies
involved in lead poisoning prevention acknowledge that primary
prevention is preferable, yet our efforts continue to focus on
screening children for elevated blood lead levels and controlling lead
hazards only after a child has been unduly exposed. Until we shift our
efforts toward the primary prevention of childhood lead exposure, we
will inadvertently but knowingly continue to use children as biologic
indicators of substandard housing (67).

Mr. Gillmor. Thank you very much, Doctor, and we appreciate
you coming.
Let us proceed to the first round of questions. My first
question would be for you, Mr. Rutherford. I believe that ASDWA
opposes a maximum containment level standard for lead in
drinking water. Is that correct?
Mr. Rutherford. Our recommendation is that we retain the
aspect of the rule with an action plan, and so forth.
Mr. Gillmor. All right. And, Mr. Stovall and Mr. Correll,
Mr. Ramaley, would you agree with that assessment by Mr.
Rutherford?
Mr. Correll. Yes.
Mr. Stovall. Yes.
Mr. Ramaley. Yes.
Mr. Gillmor. All right. And back to Mr. Rutherford, you did
mention that ASDWA is willing to work with EPA on reviewing the
lead and copper rule, because certain revisions need to be made
to the rule. Could you elaborate on what revisions you think
need to be made?
Mr. Rutherford. I think we need to review the rule, and I
am not sure it necessarily--what specific changes we might need
to make. But we did have 2 or 3 suggestions for that, and the
one that I think is most important is that the current rule
requirements related to non-transient, non-community water
systems, which in many States are typically schools and places
where people go every day to work, it is not--if those systems
are part of a host system, it is not clear how well those are
being sampled. And we may want to look at special provisions
for those kinds of places.
If they have their own sources of supply, they are already
testing under the lead and copper rule, but the others aren't.
So that would be the most significant recommendation that we
would make. And then we have a couple of others that mostly
would kind of reduce some of the reporting burden and some
ongoing monitoring that wouldn't be necessary. But that one in
particular is one that I would like to most explore with the
agency.
Mr. Gillmor. Thank you very much.
And, Mr. Colangelo, I think it is apparent from today's
testimony that there is not a consensus for creating an MCL for
lead in drinking water. You had testified that a second best
alternative, the EPA rule needs a serious overhaul. And what
suggestions specifically would you make for that overhaul?
Mr. Colangelo. Well, NRDC's position is that, first, the
lead and copper rule should be replaced by an MCL. And the
situation in DC is a perfect example of why, under the lead and
copper rule, if under 10 percent of the samples are over the
action level that is no problem. But if over 10 percent are
over the action level, that is a problem.
And so what happened in 2000 to 2001, 5 out of 52 samples
came in----
Mr. Gillmor. That not my question.
Mr. Colangelo. Sure. Assuming that----
Mr. Gillmor. My question was: what specific suggestions
would you make for the overhaul?
Mr. Colangelo. Assuming that there is no MCL, I think one
of the first things we would do to change the lead and copper
rule is to make lead-free really mean lead-free as opposed to
up to 8 percent of fittings and solder can be lead. So our
first step would be lead-free should really mean lead-free.
I think we would also require more clear and better public
education efforts, and what we see from what happened in DC is
that sending notices to The Washington Post and The Washington
Times, even if it did include the required language, that
wasn't sufficient. And when we have access to e-mail or
internet or cable news, there are other ways and there are more
creative ways to make the public aware of the problem. So that
once WASA did start to tell people about it it doesn't linger
in the background, and it really does get some attention.
So those are two of the most important things we would
change, and other changes are outlined in our written
testimony.
Mr. Gillmor. Thank you.
And now, Mr. Stovall, your written testimony talks about
funding concerns for security need at drinking water delivery
facilities. And during our committee's consideration of a
bioterrorism bill that provided standards and funding for
drinking water utilities to upgrade their systems to confront
new terrorism issues, AWWA and other drinking water utilities
argued that putting funding in the drinking water revolving
fund would chill activity, and a better method would be direct
funding.
Now, with the lack of funds that you have identified in
SFR, and the need to be able to face terror quickly, why are
you now advocating for a system that you would consider both
underfunded and too slow? Has something changed?
Mr. Stovall. No, sir, nothing particularly has changed. The
concept of using the SRF mechanism to get money to systems all
across the country, large and small, is a very valid and
effective one, and has proven to be extraordinarily successful.
That is an avenue that can help direct some funds perhaps
toward hardening our systems.
But mostly for large capital investments that had to do
with hardening a system, water system in particular, that would
significantly deplete those funds under the SRF. Funds are
scarce. Other needs exist. And if heavy hardening is required,
perhaps other funding mechanisms may be appropriate.
Mr. Gillmor. Thank you very much. My time has expired, and
I would just take note of the fact that bells are going off,
which indicates that we are going to do a series of votes. But
hopefully we can conclude and still be over there in time to
vote.
Let me go to the ranking member for questions.
Ms. Solis. Thank you. I don't know if I should say saved by
the bell.
Because I feel like we really need to have a much longer
discussion. But I wanted to ask our witness, Dr. Lanphear, if
you could describe to me at what levels would water be lead-
free that would not be harmful to children? At what parts per
billion could you identify?
Mr. Lanphear. Well, I think I would reflect what EPA said
back in 1991, that the goal should be zero. Now, that is going
to take some time, but I think we are at a point now where
there has been----
Mr. Gillmor. Could you use the mike, if you don't mind.
Mr. Lanphear. Yes, I am sorry. I would first reflect what
the EPA said 10 or more years ago that the goal should be zero.
I think the question is, now that we have made some progress in
reducing the levels over the past 10 or more years, can we now
set new goals? And I would suggest, from the standpoint of
children's health, yes, it would be worthwhile and important to
do so.
When we look at the relationship of lead contaminated water
and children's blood lead levels, even after taking into
account paint, income of the family, mouthing behaviors, and so
forth, there is no threshold. There is no apparent threshold.
At any level it will, to a greater or lesser extent, increase
children's blood lead levels and pregnant women's blood lead
levels.
We also see no threshold when it comes to looking at the
impact of lead exposure on children's intellectual abilities.
And so I would say and agree with the EPA that the goal should
be as close to zero as we can get it over the next decade or
more.
Ms. Solis. And I know some States are doing a much better
job in trying to educate. Could you elaborate on maybe some
innovative things that other parts of the country are doing to
help address this?
Mr. Lanphear. I am not sure. I would say that for the most
part we are doing a good job anywhere in the country except
where there are strong community groups who are pushing for
changes. Right now, I get 2 to 3 phone calls a week from moms
mostly.
I don't have any place to turn them to. I have to provide
answers to them, because CDC has not responded to what their
concerns are, and that is mothers are becoming more and more
concerned about lower blood lead levels, whereas our Federal
agencies have not responded to those new studies as of yet.
Ms. Solis. Could you tell me what the impact of the 300 ppb
would be? What effect does that have over a short period of
time for a child, or a pregnant mother?
Mr. Lanphear. When you say 300 ppb--oh, in terms of the
water lead levels of 300 parts per billion.
Ms. Solis. Yes. It was found here in DC.
Mr. Lanphear. Yes. It is very hard, because we don't have
specific data on that. I could go to a paper and provide you
with one estimate. I think one of the points that has been made
here is that if water--if lead contaminated water was the only
source, except in very unusual cases, it is unlikely that that
child will have a blood lead level that exceeds 10 micrograms
per deciliter. So that is not really what we are talking about
as much as incremental increases.
Now, I would say if you go back to a Boston study where
children in their first year of life who had blood lead levels
in excess of 25 micrograms per deciliter, many of them, it was
believed at the time, had levels that were excessive because of
lead in water. They did not do a thorough job, though, of
trying to explore other sources.
It is clear, though, that lead in water is an important
source. Our estimates from our study in Rochester, New York,
suggested, as the EPA did, about 20 percent of a child's blood
lead level, children in the first 2 years of life, comes from
lead and water. But it is also clear that as other sources are
reduced, the amount from lead and water will increase, or the
proportion of a child's lead exposure will increase.
Ms. Solis. And my next question is for Mr. Stovall. It
sounds to me as though you are suggesting that there is going
to be a big gap in funding if we continue on this path. What is
your opinion about the current request that is being made by
this administration for the revolving fund?
Mr. Stovall. Well, certainly, we would like to see that
funded a little bit higher.
Ms. Solis. At what level?
Mr. Stovall. Well, I would have to--I will be happy to get
back to you, but I would like to obtain that information
through our Water Utility Council and provide that data to you,
what the recommended number would be. But it is--again, there
is----
Ms. Solis. But would you say that it is not currently
sufficient?
Mr. Stovall. I think we would need to take a look at the
sufficiency of it. I don't know that I could make a
determination at this juncture whether it is or is not.
Ms. Solis. Mr. Correll, I would ask you the same question.
Mr. Correll. We would certainly support higher levels over
time. I don't have a specific recommendation of a dollar amount
today. Our major issue in the past has been to make sure that
everyone had equal access to the State revolving funds.
Ms. Solis. And would you say that as well, Mr. Ramaley?
Mr. Ramaley. I think at the current levels of $850 million,
and considering that a very small percentage of that actually
goes to municipal systems which are the largest, where most
lead service lines are located, it is clearly not adequate for
that. I think some of the estimates that have been made for a
revolving fund, if the intent is to address lead service line
replacement issues, would have to be in the order of magnitude
of perhaps $15 billion over 5 years.
Ms. Solis. Yes. And I believe that is what, Mr. Stovall,
you are reporting here in your testimony. You are actually
saying that at least $15 billion over the next 5 years should
be provided in Federal assistance to community water systems.
Mr. Stovall. Yes.
Ms. Solis. That is correct?
Mr. Stovall. That is correct.
Ms. Solis. And Mr. Rutherford?
Mr. Rutherford. The Association has made a recommendation
that the SRF be funded at $2 billion per year. And failing
that, certainly the full authorization amount as well. We have
also recommended that we make up for the shortfalls over the
last 7 years of the fund as well.
Ms. Solis. All right. And, Mr. Colangelo, could you talk a
little bit about the maximum contaminant level and what that
would mean if EPA were to come up with something, so that we
could begin to structure something and start to address some of
the issues that were raised.
Mr. Colangelo. Sure. Under the Safe Drinking Water Act, EPA
would set both a maximum contaminant level goal, which is
aspirational, and then a maximum contaminant level, which is
considered feasible and affordable. I think for lead it is
clear that a maximum contaminant level goal would be zero, and
then EPA would set an MCL of either 10 or 15 based on all of
the science.
And what that would mean is that, for example, in the case
of DC, if there were detections that came in over 15, those
wouldn't be okay as long as they were fewer than 10 percent, as
is currently the case. Under the lead and copper rule, those
would be violations of the MCL. So any detection coming in over
the level is a violation. It would be more enforceable and less
subject to the kind of vagaries of the data that we saw in the
past few years in WASA.
Mr. Gillmor. Time has expired.
Ms. Solis. Thank you.
Mr. Gillmor. Let me just make one brief comment on
authorization levels. I mean, we could authorize $100 billion
or a trillion and make us look good. But what ultimately counts
is how much money actually gets squeezed out in the budget, and
that is not something we do.
I am going to keep the record open for 7 days for any
members to submit further questions. We would appreciate if you
could answer any questions that might be submitted, hopefully
in a timely fashion. We would like to be able to close the
record on the hearing in 30 days.
I want to express my appreciation, and the appreciation of
the subcommittee, for all of you coming and for your helpful
testimony.
Thank you very much.
[Whereupon, at 12:28 p.m., the subcommittee was adjourned.]
[Additional material submitted for the record follows:]
Association of State Drinking Water Administrators Responses to
Questions of the Subcommittee on Environmental and Hazardous Materials
Question 1. You mention the importance of addressing lead pathways
in drinking water to daycare centers and schools. Has ASDWA been a
partner in EPA's efforts under the Lead Contamination Control Act
(LCCA) and other initiatives headed by Mr. Grumbles to address these
concerns? Do you believe these are effective and what else should be
done?
Response: Yes, ASDWA and states have been partners with EPA in
these efforts and stand ready to work with the Agency and other
drinking water stakeholders to explore ways to continue to reduce
waterborne lead exposure at schools and daycare centers. In response to
a March 18, 2004 letter from Mr. Grumbles on this topic, states
indicated that, in general, they implement the requirements associated
with the LCCA and continue to focus on ensuring that schools with their
own water systems are in compliance with the Lead and Copper Rule
(LCR). Some states have gone well beyond existing Federal regulatory
requirements to further improve drinking water quality and
environmental health at schools and daycares--including expanded
monitoring activities, replacement of lead-lined water coolers,
outreach efforts, and partnerships with other organizations. However,
states have also indicated that, without significant additional Federal
funding, it will be difficult to continue to expand these programs, in
view of the currently inadequate Federal support for state drinking
water programs. (See response to question #3 below.)
We believe the various lead reduction program initiatives
undertaken by states have been effective, but it is difficult to
quantify their effectiveness, since exposure to lead via drinking water
is only one route of lead exposure, and, in many cases, not the
principal route of exposure. States do not have a specific set of
national initiatives in response to the ``what else should be done''
portion of your question, but look forward to discussions of such next
steps in the coming months.
Question 2. Many people are concerned that the information in the
Safe Drinking Water Information System (SDWIS) database is incomplete.
Do you agree? If so, what are states doing to eliminate gaps in
information that EPA needs in order to get a more complete
understanding of the national drinking water picture?
Response: In April 2004, EPA released a report entitled ``Data
Reliability Analysis of the EPA Safe Drinking Water Information System/
Federal Version and Plan.'' That report indicated that the drinking
water data in the federal database (``SDWIS-FED'') were accurate (i.e.,
the available data in the Federal system agreed with the information in
state databases) but were incomplete (not all of the data that should
have been in the Federal system were there). There were a variety of
reasons for this situation, including technical difficulties in
transferring data from states to the Federal system. States and EPA are
currently working together to review the findings of the report and
determine how to implement the recommendations contained therein to
improve data quality.
Historically, most state drinking water data have been stored in
state-developed data management systems and periodically transferred to
the Federal database (SDWIS-FED). Over the past decade, EPA has
developed and made available to states a data management tool, known as
SDWIS-STATE, for tracking drinking water compliance data at the state
level. In response, many states have converted their data management
systems from unique, state-developed systems to SDWIS-STATE. The pace
of such conversions has picked up dramatically in recent years to the
point where we expect, within the next year or two, that approximately
40 states will be using SDWIS-STATE. This situation should greatly aid
in the uniformity and compatibility of data management and data
transfer between states and EPA.
Another promising initiative that will significantly aid state and
EPA efforts in this regard is an overall effort currently underway to
modernize SDWIS and streamline the way data are expressed, transferred,
and stored. The principal components of this new network will be
developed and in place over the next two years (many are already
available and being used) and we expect to see some fairly dramatic
improvements in data reliability as a result. Additionally, states have
been working with EPA to ensure that lead data in the EPA database are
current and accurate.
Question 3. The last time you testified before our committee you
talking about specific numbers that should be allocated to the Drinking
Water Revolving Loan Fund. Your testimony on July 22nd clearly stated
ASDWA's support for the reauthorization of the DWSRF as the primary
vehicle for drinking water infrastructure. Turning to state resources,
two years ago, you mentioned a ``funding gap'' of $220 million to $300
million by Fiscal Year 2005 in the federal Public Water Supply
Supervision (PWSS) grant level. Since we are there, could you please
tell us how clear your crystal ball was on that day and what you expect
in upcoming years?
Response: You have accurately captured our overall point of view
with respect to drinking water infrastructure. As noted in our
testimony of July 22nd before your Subcommittee, we believe that the
DWSRF should continue to be the primary funding vehicle for
construction of drinking water infrastructure. We do not believe that
creating new funding vehicles would comport well with the momentum
developed by the DWSRF program. While additional funding is certainly
needed, we would encourage Congress to direct such funding to the DWSRF
program. EPA's drinking water infrastructure gap estimates for the next
twenty years range from $178 billion to $475 billion (depending upon
the set of assumptions one makes). Under any set of projections, the
needs are great and adequate funding of this important program should
be a priority, in our view.
You also asked about state drinking water program resources. I'm
afraid the figures cited in your question (a state resource gap of $300
million in FY 2005) are not those that I mentioned in my testimony.
Please allow me to clarify the record. In ASDWA's testimony before the
House Appropriations Committee--both this year and last--we referred to
ASDWA's state resource needs report, entitled ``Public Health
Protection Threatened by Inadequate Resources for State Drinking Water
Programs.'' This report was a census of all 50 states (i.e., rather
than an extrapolation of information from a limited number of states.)
Thus, we believe the numbers to be quite accurate for a study of this
type. The overall findings in that report were that a gap of
approximately $230 million existed in 2002 between the funds available
to administer state drinking water programs and the funds actually
available. That funding gap is projected to grow to approximately $370
million by 2006. State resources continue to be severely strapped and I
would estimate that the gap by 2006 will be at least the amount we
projected a few years ago. The PWSS Federal grant program used to
constitute the lion's share of funding needed to run state programs but
has made up a steadily decreasing share, since Federal funding has
essentially been ``flat'' for the past several years. Meanwhile, the
demands on state drinking water programs have increased dramatically
since the enactment of the 1996 amendments to the Safe Drinking Water
Act and the advent of all of the security needs in the wake of the
events of September 11, 2001.
In addition to PWSS grant funds, many states are able to fund
substantial elements of their state drinking water programs from
various ``set-asides'' allowed by the DWSRF. These set-asides are fixed
percentages of the fund that may be used by states for various state
program activities such as providing technical assistance to drinking
water systems; developing and implementing drinking water system
capacity development programs; and administering drinking water system
operator certification programs. Thus, sustained and enhanced funding
for the DWSRF programs, as advocated above, not only provides loan
funds for critical infrastructure needs but also helps address part of
the state drinking water program resource gap I have described.
Question 4. Your organization is responsible for enforcing the
drinking water laws of the Federal government in your state. Mr.
Johnson [of the D.C. Water and Sewer Authority], argued that the
District of Columbia should be given primacy to operate their drinking
water program. In view of their past performance, do you think they
have the wherewithal to do it?
Response: States may apply for ``primacy'' to administer federal
drinking water regulations, provide they meet the requirements set
forth in the Federal regulations at 40 CFR Section 142, Subpart B. The
requirements include state regulations (that must be at least as
stringent as their Federal counterparts), adequate authority to enforce
these regulations, and a variety of technical and programmatic
capabilities. Please also note that a state cannot apply for primacy
for only a single rule (such as the Lead and Copper Rule). States must
seek primacy approval for all Federal drinking water regulations.
ASDWA is not in a position to judge whether or not the District of
Columbia has the wherewithal to operate such a program in light of
recent events. If the District wished to pursue this course of action,
they would need to compile a primacy application that met all of the
relevant regulatory requirements and submit this to U.S. EPA. The
Agency would then need to carefully evaluate this application and make
the appropriate finding.

Natural Resources Defense Council
August 18, 2004
The Honorable Paul E. Gillmor, Chairman
Subcommittee on Environment & Hazardous Materials
1203 Longworth House Office Building
Washington, DC 20515
Dear Representative Gillmor, thank you for the opportunity to
testify before the Subcommittee last month for the hearing entitled
``Tapped Out? Lead in D.C. and the Providing of Safe Drinking Water.''
This letter is in response to your letter of August 3, 2004, requesting
that NRDC answer the four follow-up questions listed below.
Question 1. Can you describe for us the relationship between the
water distribution system and protection of the public health, be it
wastewater or drinking water?
Response: Deteriorating or inadequate drinking water distribution
systems, particularly in combination with deteriorating or inadequate
sewage pipes, can pose significant public health risks that need to be
addressed by EPA rules. First, aging infrastructure causes more than
200,000 water main breaks per year, which can cause back-siphoning of
contaminants and infiltration of contaminated water from groundwater
through pressure loss. This is an especially troublesome issue when a
water main break occurs near leaking sewage lines. Second, poorly
maintained and aging pipes can lead to biofilms, regrowth,
nitrification, and resulting buildup of bacteria and perhaps other
pathogens. Scientific studies, including those of Dr. Pierre Payment (a
leading international drinking researcher at the prestigious Institut
Armand-Frappier in Canada), indicate that a significant percentage of
diarrheal disease and gastrointestinal distress may be caused by
bacteria and pathogens in the water distribution system. Third,
inadequate infrastructure also can create problems with microbial
regrowth due to water age from, for example, dead ends in distribution
pipes and lack of turnover in water storage. Fourth, as seen in D.C.
recently, lead contaminates drinking water by leaching from lead
service lines, goosenecks, and other lead components in old pipes.
Fifth, cross connections can cause chemical and microbial contaminants
to reach drinking water. Sixth, plastic pipes can allow permeation of
solvents and organic chemicals that contaminate groundwater in
brownfields or near leaking underground storage tanks (``LUST'').
Seventh, uncovered finished water reservoirs in some cities can allow
serious bacterial and other contamination by birds and surface water
runoff.
EPA and industry consultants have prepared a series of white papers
that outline each of these potential adverse public health consequences
of inadequate infrastructure in greater detail. See EPA, Distribution
System White Papers, at http://www.epa.gov/safewater/tcr/
tcr.html#distribution.
Question 2. In light of Mr. Grumbles testimony, assessing the
pervasiveness of the lead contamination problem nation-wide, what is
your estimation of the remaining threat of lead in the water
distribution system?
Response: There are significant problems with lead in many cities.
EPA has not done a good job of keeping on top of the problem and
assuring adequate monitoring and follow-up in cities that are at or
close to the action level. Mr. Grumbles testified during the
subcommittee hearing that lead in drinking water is not a national
problem. However, EPA's survey of medium and large systems has found
that at least 10.2 million people are served by systems with lead
contamination problems. Moreover, NRDC believes that careful auditing
and monitoring of other cities will likely turn up additional lead
problems.
Question 3. Do you agree with the assessment of some other
witnesses that water service, in particular drinking water, has been
under priced?
Response: Drinking water is cheaper in most cities than other
utilities including cable TV, telephones, cell phones, electricity,
gas, etc. We are generally living off infrastructure investments made
by earlier generations. In some cases, the price charged for water does
not reflect the full cost of delivering the water, and as more water
infrastructure investments are made, these costs are likely to increase
in many areas. However, as we move towards higher water prices due to
the need to replace and upgrade aging infrastructure, it is important
to keep in mind that some low-income members of society will have
difficulty paying their increasing water bills and other necessities.
We recommend the establishment of a Water HELP (HElp for Low-income
People) Program akin to the LIHEAP program for energy assistance, and
lifeline rates for low-income residents. Furthermore, NRDC endorses
increased funding for the Drinking Water State Revolving Fund, with
special consideration given to assisting small systems. Finally,
comprehensive water infrastructure assistance legislation, including
creative solutions to the funding gap, is needed to help cities and
towns pay for their needed water infrastructure improvements.
Question 4. Do you or NRDC have any independent quantification of
what you see as the drinking water funding gap?
Response: No. We rely upon the estimates provided by EPA, the Water
Infrastructure Network, and the Congressional Budget Office.
Thank you very much for the opportunity to testify and to answer
these follow-up questions.
Sincerely,
Aaron Colangelo
______
Thomas Jacobus, General Manager, Washington Aqueduct, U.S. Army Corps
of Engineers, Response for the Record
Question 1. Your testimony states that the Washington Aqueduct
recently switched to a new corrosion inhibitor chemistry based on an
orthophosphate compound over the use of chloramines. Could you please
tell us what the disinfectant by-product trade-off is between the
current chemical regime and the one used before? If the current
chemical treatment protocol remains effective, would you recommend that
it become a more permanent feature?
Response: I should clarify that for our entire service area,
Washington Aqueduct expects to begin feeding orthophosphate as a
corrosion inhibitor on August 23, 2004. For a small area in the
District of Columbia, we began a partial system application of
orthophosphate on June 1, 2004. That independent local application will
cease when the full system application begins since the full system
application will cover this smaller area as well.
The decision to add a corrosion inhibitor was independent of the
decision to switch from chlorine to chloramine as a distribution system
disinfectant. The corrosion inhibitor and the disinfectant are both
important parts of the overall treatment process, but they do very
different, and independent things. The corrosion inhibitor reduces the
naturally corrosive effect of the water when it comes into contact with
pipe and plumbing surfaces. The disinfectant kills bacteria that could
cause gastrointestinal distress in humans.
The planned full application of orthophosphate as a corrosion
inhibitor is a new step to enhance the optimal corrosion control
treatment, which heretofore has been accomplished by the use of lime to
raise the pH of the water leaving the plant.
The change in secondary disinfectant was undertaken in response to
the Disinfectants and Disinfection Byproducts Rule, which reduced the
allowable concentration of total trihalomethanes in the distribution
system. Prior to the fall of 2000, the Washington Aqueduct used free
chlorine for both primary (treatment plant) and secondary (distribution
system) disinfection. Since November 1, 2000, Washington Aqueduct has
used free chlorine for primary disinfection and chloramine for
secondary disinfection. Since converting to chloramines we have
observed a dramatic decrease in disinfection by-product formation.
Previously, the District of Columbia distribution system's running
annual average for total trihalomethanes was 75 micrograms/liter; since
converting to chloramines, the running annual average is now 40
micrograms per liter.
We intend to continue to use chloramine to keep the disinfection
byproducts low, and we expect that the addition of the orthophosphate
corrosion inhibitor will over time (in the presence of the chloramine
disinfectant) reduce leaching from lead surfaces by establishing a
mineral film on those surfaces.
Question 2. Is the orthophosphate regime simply the fastest
combination to achieve the reductions in lead or is it the most
effective? Please explain what other alternatives were contemplated for
this situation and why they were not used? What has this treatment
regime meant for intended water line replacement? Is replacing all the
lead service lines a reasonable thing to do if such progress is being
made?
Response: In terms of corrosion inhibitors in use around the United
States there is no one chemical that has been shown to be faster than
another. The orthophosphate regime is the most commonly used corrosion
inhibitor, and it has been extremely successful in reducing corrosion
potential nation-wide. Zinc orthophosphate was contemplated; however,
there were some concerns regarding zinc's impact on biological
wastewater treatment. After consultation with nationally regarded
experts, we recommended to EPA Region III that we use orthophosphate as
the corrosion inhibitor. They have subsequently issued us an interim
Optimal Corrosion Control Treatment directive incorporating
orthophosphate, which we will follow.
Other inhibitors (such as silicates) were ruled out through the
desktop corrosion study as not being as effective for the water quality
of treated Potomac River water in terms of corrosion abatement.
Corrosion scientists working for EPA and in private industry with
whom we have consulted have offered some ideas about the role chlorine
may play in creating a lead oxide coating in service lines. That would
suggest that the use of free chlorine in conjunction with an
orthophosphate corrosion inhibitor might form protective scales more
expeditiously than the corrosion inhibitor in the presence of
chloramine. In order to comply with the EPA rule on disinfection
byproducts it will not be possible to change the disinfectant from
chloramine to chlorine. Were we to do so, the levels of total
trihalomethanes would exceed current regulatory standards. Lowering the
trihalomethanes levels was the purpose of conversion to chloramine as
the distribution system disinfectant in the fall of 2000. However,
Washington Aqueduct, in cooperation with Region III of the
Environmental Protection Agency plans to conduct a study to see what
combination of other treatment changes might be possible in the future,
to allow free chlorine to be used. While that is being studied, more
scientific research can be done on the aforementioned hypothesis.
Under EPA regulations, once a system's required monitoring under
the Lead and Copper Rule achieves levels below the action level for two
consecutive periods (one year in the case of the District of Columbia)
it is possible to suspend the replacement of lead service lines. This
is based on the logic that the passivating chemical (i.e., the
orthophosphate) has done its job and lead release has been reduced to
the limits in the rule. However, the decision to cease lead service
line replacement is in the hands of the District of Columbia Water and
Sewer Authority and EPA Region III, not Washington Aqueduct. We will
continue to feed an appropriate dose of corrosion inhibitor regardless
of what decision is made about lead service line replacement.
I must defer to the District of Columbia Water and Sewer Authority
Board of Directors and the Authority's General Manager to comment on
what they believe is reasonable in this regard. However, I would say
that the issue of the public portion versus the private portion of the
lead service line is important. If only the public portion is replaced,
there still will be water flowing through lead pipes. From our
perspective, that is why it is so important that we continue to achieve
optimal corrosion control treatment for water leaving the treatment
plants.
Question 3. Your testimony states that the District of Columbia,
Arlington County, and Falls Church all conducted studies to determine
the optimal corrosion control. Did all of them decide on the same
treatment regime? Did any of them ask for something else and, if so,
what was it?The intent of my testimony concerning the initial studies
done to determine an appropriate optimal corrosion control treatment in
response to the 1991 Lead and Copper Rule was to point out that
Washington Aqueduct consulted with its customers and kept them apprised
of the results and recommendations of Washington Aqueduct's consultant.
Those jurisdictions took no active part in conducting those studies.
But what they did do was to evaluate the consequences in their
wastewater collection and treatment systems of the use of a phosphate-
based inhibitor. Since at the time of the study all three customers
were meeting the Lead and Copper Rule action level, they individually
informed EPA Region III that they were in favor of Washington Aqueduct
using pH control with lime.
Response: In the analysis and decision-making of the last few
months, all of Washington Aqueduct's wholesale customers, as members of
the technical expert working group have agreed to proceed with the
phosphates. As I said in the response to the previous question,
Arlington County did raise the question about the suggested use of zinc
orthophosphate and their concerns were evaluated and the group and the
independent peer review panel accepted the use of orthophosphates,
without the zinc, as the chemical to use as part of the optimal
corrosion control treatment revisions now approved by the Environmental
Protection Agency.
Question 4. Your testimony mentions that the Washington Aqueduct
paid ``very close attention'' to water chemistry and the samples taken.
If that was the case, was the Washington Aqueduct curious at all when
D.C. WASA was able to get under the Federal lead action level for 2001
when it seemed almost certain from several other reports that they
would exceed it? Did the Aqueduct and D.C. WASA ever compare notes or
samples to see if the results tracked each other?
Response: The Washington Aqueduct organization is both vigilant and
engaged with respect to its water production responsibilities. We are
keenly aware of maximum contaminant limit thresholds that apply to both
production and distribution system water quality. We look daily at our
customers' performance under the Total Coliform Rule and their monthly
and quarterly and annual compliance with the Disinfectants and
Disinfection Byproducts Rule and consult with both them and EPA Region
III routinely and by exception to alert them to any signs of impending
rule violation or a matter potentially affecting public health.
When we analyzed lead and copper samples for our customers, the
laboratory chief would immediately notify the customers' water quality
managers (this would include DC WASA of course) if any lead sample was
greater than 15 micrograms/liter.
But unlike the other rules, with these lead samples, no individual
value necessarily created an exceedance of the Lead and Copper Rule.
Since we were not managing the number of samples drawn, we therefore
were not able to monitor what was occurring at the 90th percentile.
We have certainly learned from the experience in 2004 that we could
have been more engaged to help our customers, and we are making new
efforts to systematically share more information with each other on
these and other quality water production issues. For example, reports
that went from WASA to EPA will now be shared with Washington Aqueduct
so that we get a look at the bigger picture.
All during this time, Washington Aqueduct was operating under an
Optimal Corrosion Control Treatment (OCCT) regime that had been
directed by EPA. We paid very close attention to the chemistry that
would achieve compliance with that OCCT. That is what I was referring
to in my testimony. We do not have authority to change treatment
independently. We need EPA's approval. So it is important that the
Washington Aqueduct, DC WASA, and EPA are able to evaluate the
situation from a common perspective. That certainly is a lesson learned
and it will improve in the future.
Question 5. Your testimony mentions that the high lead levels in
D.C. drinking water in 2002 and 2003 ``indicated that Washington
Aqueduct's optimal corrosion control treatment'' was ``no longer giving
adequate protection.'' What actions did the Washington Aqueduct take in
2002 after D.C. WASA reported that their lead levels exceeded Federal
standards? If lead samples were showing problems in 2001 and 2002, why
did it take until 2004 until the Corps executed a change in the
corrosion control treatment?
Response: In my testimony about the protectiveness of our optimal
corrosion control treatment, I was attempting to be retrospective in
drawing a conclusion from all of the analysis we had done in early
2004. Thus, my comment was meant simply to be about the effectiveness
of our corrosion treatment in 2002 and 2003; my statement was not
intended to (falsely) suggest that in 2002 we knew the treatment was
not effective and that we waited until 2003 to act on that knowledge.
The Washington Aqueduct plant operations group prepares weekly
reports that evaluate water chemistry and those reports are routinely
sent to Aqueduct managers so we can pay very close attention to
chemical dosages and equipment maintenance to ensure that we are
efficiently operating within the acceptable range of water chemistry
that achieves the optional corrosion control treatment as approved by
EPA. We were therefore focusing more on the plants' operation and
relying on the customers to do their lead sampling. Had we worked more
collaboratively, I now believe we could have started work on a revised
treatment sooner.
Washington Aqueduct was contacted by consultants hired by DC WASA
and EPA Region III in 2003 to investigate the increased levels in lead
in compliance samples from the DC WASA system. We shared water quality
data and information on the treatment process with them and cooperated
in their study. That study was the starting point for the accelerated
work started in February 2004 that has now resulted in a revised
Optimal Corrosion Control Treatment, which will incorporate a corrosion
inhibitor in addition to the use of lime to adjust pH.
What still remains to be understood is whether the simultaneous
compliance with the Lead and Copper Rule and the Disinfectants and
Disinfection Byproducts Rule and our decision to reduce Total
Trihalomethanes through the use of chloramine as the secondary
disinfectant in 2000 actually contributed to the lead leaching problem.
It has been speculated that chloramines can indirectly cause water to
become more corrosive through a process called nitrification, and the
distribution system was monitored to ensure that this was not
happening. I believe our decision to change disinfection chemistry was
based on the best professional judgment available.
As I described in my response to the previous question, we did know
that specific samples were above 15 micrograms/liter but we did not
have the complete data set from DC WASA from which to draw general
conclusions about fundamental changes in lead release. Since we did not
have any indication that our other customers were seeing higher lead
levels, there was no mutual understanding that there might be a problem
with the corrosion control treatment.
Question 6. Your testimony states that the Corps is approaching the
treatment protocol in two steps to ensure that unexpected ``secondary
effects'' are controlled. Could you please explain what these might be?
Other than rust, are there any other serious public health issues that
might arise from these activities?
Response: There are two major secondary effects that might occur.
One is dissolution of rust and localized discoloration of water. That
is a transient phenomenon and easily handled through flushing. The
other potential effect is increased levels of coliform bacteria in the
distribution systems. This would be caused by the sloughing of biofilms
from the interior surfaces of the pipes. The kinds of coliform bacteria
that would be involved pose no health risk, and increases in their
levels would indicate the need for system flushing to remove biofilm
materials.

Bruce P. Lanphear, Cincinnati Children's Hospital Medical Center,
Response for the Record
Question 1. Thank you for your testimony. Indeed, everyone agrees
we should do what we can to prevent children from being exposed to
excessive levels of lead contamination from whatever source. You state
in your testimony that most lead exposure to children comes from lead-
based paint in older houses and lead-contaminated soil but that intake
of lead-contaminated water, by itself, would be an unlikely cause of
elevated blood levels of lead in children. You go on to say, however,
that since there is no apparent threshold amount of lead in the blood
to experience the adverse effects of lead exposure, all sources of lead
exposure should be limited. As policymakers interested in doing the
most to limit lead exposure, should we focus our resources on old
paint, contaminated soil or removing lead from drinking water
infrastructure?
Response: This is an old debate. In the 1970s the US EPA argued
that the predominant source of lead exposure for children was housing
whereas the US Department of Housing and Urban Development argued that
it was the ``environment''. This debate was primarily a way for both
agencies to shift the burden and cost of regulation or abatement to the
other agency. What we have found over the past 30 years is that lead
toxicity is due to cumulative exposure from a variety of sources in
housing and the broader environment. But with the phase-out of leaded
gasoline, residential lead hazards, including lead in paint, house
dust, soil and water have become increasingly important.
If we prioritized the relative contribution of various sources of
lead, we would list lead-contaminated paint, house dust and soil as the
primary sources of childhood lead intake for children who live in older
housing. But lead-contaminated water is contributing a comparable and
increasingly greater proportion to children's lead intake as these
other sources of lead exposure are diminishing. Moreover, lead-
contaminated water accounts for a greater intake among middle-class
families and their children who live in housing built after 1978. Thus,
any strategy to protect children from adverse consequences of lead
toxicity must reduce lead exposure from all of these major sources of
lead intake, including water.
Question 2. In your discussion of the level of blood concentrations
in children that may be considered ``normal'' you stated that children
of today have a body lead burden 10 to 100 times higher than pre-
industrial humans. You cite a study as your source but there's no
supporting evidence in your statement. Can you explain what you mean by
a ``body lead burden''? If you are familiar with the study you cited,
can you describe the study, its findings, and its significance for us
as policymakers?
Response: There are several studies that examined the total amount
of lead found in humans (i.e. body burden of lead). This was reviewed
by the National Research Council of the National Academies of Science
in their 1993 report ``Measuring lead exposure in infants, children and
other sensitive populations.'' Because the vast majority of lead is
found in human bone, researchers used the concentration of lead in bone
to measure the increase in body lead burden from pre-industrial humans
to contemporary humans.
The relevance is that while a blood lead concentration of 5
micrograms per deciliter is ``low'' by contemporary standards, it is
actually considerably higher than exposures experienced by humans
before the industrial revolution. Moreover, whereas the regulation of
most toxic substances is based on safety factors so that the presumed
safety factor is set to be lower than the lowest-observed effect
concentration in humans by a factor of 10 to 100 (National Research
Council, Drinking water and health. Vol 6. Washington, D.C.: National
Academy Press, 1986), the current CDC action level is actually set
above the level now shown to be harmful (Canfield RL, et al.
Intellectual impairment in children with blood lead concentrations < 10
micrograms per deciliter. N Engl J Med 2003;348:1517-1526). Thus,
despite the dramatic reductions in children's blood lead levels over
the past 25 years and because there is no evidence of a threshold for
the adverse effects of lead exposure, we should develop an aggressive
strategy to further reduce children's exposure to environmental lead
from paint, house dust, soil and water.

Question 3. Mr. Grumbles noted in his written testimony that
setting a standard for water leaving the treatment plant fails to
capture the extent of lead leaching in the distribution system and
household plumbing, and so no maximum contaminant level has been
established. Instead, the EPA regulates corrosion control and may
require action if more than 15 ppb is found in drinking water. Do you
feel a stronger regulatory framework is a necessary part of a
comprehensive policy for preventing lead contamination and protecting
public health?
Response: Yes, a stronger regulatory framework is needed to protect
the public's health. The current water lead standard of 15 ppb is not
adequate to protect children and pregnant women from the adverse
consequences of lead exposure. In a recent study, we found that, for a
child with a mean blood lead level of 5 microgram per deciliter, that
20% (i.e., 1 microgram per deciliter) was attributable to children
having a water lead level > 5 ppb (Lanphear BP, et al. Environmental
lead exposure during early childhood. Journal of Pediatrics
2002;140:40-47.) While the adverse effects of a 1 microgram per
deciliter increase in blood lead level is hard to quantify for any one
child, it has substantial impact on population mean blood lead levels
and the adverse consequences of lead toxicity.
The existing screening requirements are not adequate to protect the
public's health. Water service lines and brass used in water service
lines contain excessive levels of lead. It is both feasible and cost-
beneficial to require brass fittings and valves with < 1% lead content.
Moreover, the existing standards will fail to identify and protect many
families who are ingesting high concentration of lead in their drinking
water because the routine screening fails to test or detect the
majority of housing with lead-contaminated water. Thus, the current
screening system provides an illusion of safety. Families who might
otherwise choose to test the lead in their water supply do not because
they are assured by the authorities that it is ``safe''.

Response to Questions from Chairman Paul Gillmor, Subcommittee on
Environment and Hazardous Materials, Committee on Energy and Commerce,
by Brian Ramaley, witness for the Association of Metropolitan Water
Agencies
Question 1. Your testimony highlights the need for a sharing of the
costs between the water utility and the homeowner in regards to the
removal of the whole service line. If this cost is not shared and the
utility is expected to remove the entire service line (from main to
customers' service lines) would you pass this cost on to the ratepayer?
Answer: Nearly all utilities derive all of their operating revenues
through payments from their customers. The question then is: would
utilities pass the cost for replacing privately owned service lines
directly to the affected customer or spread the cost to all customers?
In either case, ratepayers will ultimately bear the cost associated
with service line replacement without external funding. Many utilities
will choose to raise rates to all customers if required to replace the
entire service line; some will have to postpone other, previously
planned infrastructure projects; others will seek direct grants through
the appropriations process if such funds are available. Many will look
to the federal government to increase assistance for this purpose.
Question 2. Are you suggesting that not only should the funding be
increased on a federal level but also the qualifications for receiving
the funding be changed so as to channel more resources toward the
metropolitan systems? If funding is not increased, would you still like
to see the qualifications for receiving funding be changed so the
metropolitan systems receive more than 5% of the drinking water SRF
assistance?
Answer: AMWA recommends that the Drinking Water SRF be amended so
that at least 15% of federal capitalization grants to states be
reserved as loans to metropolitan systems. Another option is to require
states to select loan recipients in a manner proportionate to the needs
of each system size category. (Funds that are reserved for metropolitan
systems but not awarded due to lack of applications would be available
to other size categories.)
We do not recommend that the minimum qualifications for applying
for or receiving loans be different for each system size category. We
only suggest a fairer distribution of funds.
Question 3. Can you speak to the progress being made by publicly
owned utilities in regards to asset management programs? In addition,
what steps toward being more efficient have been implemented? (Speak to
your own experience if possible.)
Answer: Most utilities perform some form of asset management
already and water associations have made tools available for utilities
to improve their asset management efforts. Asset management is very
helpful in determining future needs and establishing maintenance
programs, but it is not in itself a cost-saving device. Nor does it
help improve the longevity of pipes or equipment. It simply allows a
utility to approach and plan for asset replacement in a more organized
and efficient manner. In this way, catastrophic failures and
unmanageable short-term expenditures can be avoided or minimized.
Metropolitan drinking water agencies have made enormous strides in
becoming more efficient. Through our Gold Awards for Competitiveness
Achievement and our Platinum Awards for Sustained Competitiveness
Achievement, AMWA has recognized nearly 100 metropolitan drinking water
systems for their achievements in becoming more efficient. Employing
new technologies, improving productivity, fostering creativity in
management and operations, and streamlining various processes have each
produced significant cost saving to ratepayers. For example, in 2002
Newport News Waterworks was recognized by AMWA for becoming more
competitive by increasing not only efficiencies, but also customer
confidence. Various measures implemented at Newport News Waterworks
have been highly successful at reducing costs. We have completed a
thorough review of our buried infrastructure (pipelines) and planned
for its replacement, and have completed renovation of most of our
aboveground infrastructure. Despite a new account growth rate of nearly
1% per year, Newport News Waterworks has not added staff since 1993.
Question 4. If federal investment in drinking water infrastructure
is increased to the benefit of publicly owned utilities serving 100,000
or more people, does that not double tax the public utility ratepayer?
Answer: All current federal funding for drinking water
infrastructure, including funds appropriated through the Rural Utility
Service for small utilities, comes from the federal government's
general treasury. Because this assistance is only a fraction of the
amount needed for infrastructure up-keep, all water utilities--large
and small--charge fees based on water consumption.
AMWA is not recommending federal or federally mandated taxes or
fees on drinking water ratepayers. In fact, AMWA would oppose such
fees. AMWA simply recommends that federal funds be made available to
metropolitan systems in a manner consistent with the needs these large
systems have demonstrated in EPA's needs surveys. Residents of
America's large cities pay federal taxes, and if their water system is
in need of federal assistance, they expect their water system to be
allowed to receive it.

Response for the Record by Donald Welsh, Regional Administrator, U.S.
Environmental Protection Agency, to Questions of Majority Members
Question 1) From March 26 to April 6 of this year, sampling at DC
public schools had identified 43 drinking water fountains and sinks
with excessive levels of lead in the water--one school had a fixture
with a lead level of 7.300 parts per billion or 486 times the Federal
Lead action level. Recognizing the impact of lead to young minds, what
is the EPA Region III doing to ensure school drinking water fountains
are not stunting work in the classroom?
Response: Outlets that serve very young children (age 6 and under)
were sampled for lead at 134 DC Public Schools (DCPS). Most sampling
occurred in March, with 4 schools sampled in early May. Out of a total
of 1,024 samples, 45 outlets (10 fountains and 35 sinks) or 4.3
percent, had results that were over EPA's Action Level for schools (20
ppb). According to DCPS, outlets with high lead levels were taken out
of service for replacement. Any replacement outlets will be tested to
make sure they are not still elevated for lead.
In mid-May, WASA conducted training for representatives of private
and charter schools, day cares, and other facilities such as libraries
and recreation centers so that those facilities could participate in
the sampling program. Additional sampling was conducted in June and 77
facilities completed the sampling per the protocol (reviewed by EPA) in
May/June. Of those tested, 18 facilities had a total of 44 outlets over
the Action Level, with the highest concentration at 125.7 ppb. DC WASA
advised the facilities to take those outlets out of service and follow
the EPA guidance for repair and follow-up sampling.
EPA has provided the DC Department of Health (DOH) with technical
assistance so that DOH can assist the facilities in taking appropriate
remedial action (installing filters, replacing fixtures, etc.) At this
time, EPA feels that appropriate actions are being taken to ensure the
health of students in D.C.
Question 2) Your testimony mentions how EPA is now spending time
helping WASA with its lead sampling, public information, and education
campaign move beyond ``baseline requirements.'' Have your experiences
with the D.C. situation made yqu more or less inclined to support
changes to the Federal standards in this area, most particularly public
notification? If they do, please elaborate on your ideas.
Response: EPA's National Primary Drinking Water Regulations
represent the minimum compliance level for public water supplies. Water
utilities are always encouraged to not only meet the requirements, but
to go beyond mere compliance as much as feasible. The sampling
requirements that have been imposed upon WASA by Region 3 are, in some
cases, more detailed than required by the regulations. EPA wanted to
ensure that in this situation, where lead levels were unprecedented and
the causative factors are still not completely understood, WASA, the
Washington Aqueduct, and EPA have enough data to advise on selection of
appropriate treatment and to monitor its effectiveness once it is put
in place. EPA believes that an aggressive monitoring program is
essential to ensure that the utilities serving the District get on and
stay on the right course of treatment and system optimization and to
properly assess the extent of the lead problem.
With respect to public notification, our experience in Washington,
D.C. clearly showed that WASA's public outreach was inadequate and did
not elicit the public reaction and response contemplated by the
regulation. EPA's consent agreement identified several areas where WASA
failed to fully comply with the regulations regarding public education.
Had WASA fully complied and undertaken activities recommended in EPA's
Lead and Copper Rule Public Education Guidance Manual, it is likely
that the public would have had more awareness of the problem.
EPA's Office of Water is attempting to assess the effectiveness of
the regulations in other communities. A workshop on Public Education
and Risk Communication has been scheduled for September 14-15, 2004, in
Philadelphia, PA, to focus on public education aspects of the rule.
Additional information should come out of that meeting that would
either support enhancements to guidance or regulatory changes.
Question 3a) Your testimony states that ``steps are underway to
reduce lead levels in tap water through corrosion control,'' including
the use of organophosphate [orthophosphate] and chlorine as opposed to
chloramines.
Response: The Aqueduct has been using pH control as its corrosion
control method for the past several years and has used chloramine as a
secondary disinfectant since November 2000 to address high levels of
disinfection byproducts in drinking water. Steps are underway to reduce
lead levels by switching to orthosphosphate as a corrosion inhibitor.
Chloramine will be maintained as a secondary disinfectant, with an
annual switchover to free chlorine for approximately six weeks every
spring to help control bacteria that adhere to water mains.
Detailed lead monitoring conducted by WASA during the switch over
to free chlorine in April 2004 found that lead levels dropped
significantly by the end of the six week period. It is believed that
the stronger oxidation ability of free chlorine virtually stopped lead
from leaching into the water. This occurred prior to the start of the
orthophosphate treatment. Research is currently being performed now to
test the effectiveness of using free chlorine in the short term to help
accelerate the effectiveness of the orthophosphate and help determine
if switching back and forth from chloramines to chlorine and back again
is also beneficial or detrimental to corrosion control.
Question 3b) Could you please tell us what is the disinfectant
byproduct trade-off between the current chemical regime and the one
used before?
Response: Disinfection byproducts, which may be harmful to human
health, are formed more readily with free chlorine, than with
chloramine. Since the November 2000 treatment change to chloramines,
which are formed by adding a small amount of ammonia to chlorine,
disinfection byproduct levels have fallen by more than 50%. The trade-
off of moving back to free chlorine with orthophosphate treatment is
that disinfection byproduct levels would increase, which could increase
the potential cancer and other health risks to the population of the
District of Columbia and the Virginia localities of Arlington County
and the City of Falls Church. Unlike lead, which is limited to specific
homes, disinfection byproducts would affect everyone in the District of
Columbia and those residents in Virginia who receive water from the
Washington Aqueduct. The increased levels could cause MCL violations in
the District, Falls Church and Arlington County. For disinfection
byproducts, no amount of tap flushing would reduce the byproduct
concentrations. Every home would see elevated levels of at least some
of the byproducts. In addition to exposure from drinking the water,
dermal and respiratory exposure could also result from bathing and
showering because some of these byproducts volatilize rapidly from
water.
Question 3c) If the current chemical treatment protocol remains
effective, would you recommend that it become a more permanent feature
in the District? Is the chlorine [chloramine] and organophosphate
[orthophosphate] regime the fastest combination to achieve the
reductions in lead or is it the most effective? Please explain what
other alternatives where contemplated for this situation and why they
were not used?
Response: In response to the problem of elevated lead levels, the
optimal corrosion control treatment (OCCT) was reevaluated. Contractors
for the Washington Aqueduct conducted a desktop study that reviewed
various options for OCCT, including pH adjustment, alone, pH and
alkalinity adjustment and the use of corrosion inhibitors. Detailed
computer modeling, which had not been available in the mid-1990's when
OCCT was initially researched, indicated that the Aqueduct would have
significant problems using a year-round, high pH to control corrosion
due to expected high levels of lime precipitation in the distribution
system. The desktop study also noted that orthophosphate would be the
best choice for re-optimizing OCCT for the Aqueduct. This was based on
a review of strategies used at other water utilities using
orthophosphate and the computer modeling results. The Aqueduct
requested EPA approval of the use of orthophosphate as their revised
OCCT. On August 3, 2004, EPA gave interim approval for orthophosphate
use along with requirements to complete pipe loop studies to test for
appropriate dosages and to compare different forms of orthophosphate
(zinc orthophosphate vs. orthophosphate). The Aqueduct immediately took
steps to begin implementing that treatment.
If the orthophosphate treatment continues without causing any
unresolvable problems in the distribution system (e.g., red water and
elevated occurrence of coliform bacteria) and the pipe loop studies
confirm its effectiveness, EPA will likely give final approval of
orthophosphate as OCCT for the Aqueduct. Lead levels in tap water may
take six months to a year or more to drop with orthophosphate
treatment. Until lead drops to acceptable levels, District residents
must continue following the flushing guidance to reduce their lead
risks--particularly those with lead service lines. Orthophosphate
treatment has enabled other large metropolitan areas to avoid having to
replace lead service lines. Although results in one city cannot be
directly transferred to expected results in the District due to
differences in source waters, treatment and distribution systems, we
are hopeful that orthophosphate will reduce lead levels to below EPA's
action level.
EPA will be working with the Aqueduct in early Fall 2004 to map out
a more holistic and detailed research plan on mid to long-term
treatment possibilities which will include the possibility of moving
back to free chlorine on a permanent basis, if this can be done while
still meeting the new MCLs for disinfection byproducts.
Question 3d) What has this treatment regime meant for intended
water line replacement? Is replacing all the lead service lines a
reasonable thing to do if such progress is being made?
Response: After one full year of lead levels at the 90th percentile
being below the action level, WASA would be allowed under EPA's
regulations to suspend their lead service line replacement program. The
decision to replace lead service lines in a water system meeting the
lead action level requirements is solely a local economic and public
policy decision.
In the District, the highest of lead levels are found in homes with
lead service lines. These homes must follow the extended water flushing
protocol and use the water filters provided to reduce their risk. Homes
without lead service lines only need to flush their tap for 60 seconds
before drinking. Residents can take these steps to virtually eliminate
their risk of lead exposure from tap water. There is no known exposure
risk to lead from skin contact or inhalation of vapors from water
containing elevated lead. The risk is solely from drinking the water or
eating some foods cooked in it. Arlington County and Falls Church,
Virginia have not experienced elevated lead levels.
Question 4) Your testimony suggests that things are getting better
in D.C. Yet, you mention that the lead test results received on July 7
indicate that the Federal lead action level was exceeded by nearly four
(4) times or 59 parts per billion. How do you square those two
statements?
Response: The testimony reported that progress is being made,
particularly in the areas of actions taken to reduce the immediate
health threat and getting new water treatment in place. The new water
treatment using orthophosphate commenced on August 23, 2004. The
installation of the treatment, and the entire process leading up to
this point has been rapidly accelerated. This pace was due, in part, to
EPA's coordination of, and participation in, the Technical Expert
Working Group.
The corrosion inhibitor treatment will take time to work.
Orthophosphate reduces lead in tap water by creating an insoluble
mineral scale on the interior of the pipes, essentially insulating the
pipe wall from the water. This reaction takes place slowly. National
corrosion experts have advised us that the lead levels may not begin to
fall for at least six months to a year, or perhaps even longer. EPA,
WASA and the D.C. Department of Health continue to urge residents in
the District to follow the tap water flushing guidance to reduce their
lead exposure risk until the lead returns to acceptable levels at the
tap.
Question 5) Could you please talk about the Technical Expert
Working Group and the Independent Peer Review Panel? Are these
permanent bodies or ones that were formed just for emergencies like
this one? How do you determine who serves on these bodies? Is the
Technical Expert Working Group a direct result of the compliance order
issued June 17, 2004?
Response: After WASA exceeded the lead action level in August, 2002
WASA and EPA recognized the need to research why tap water lead levels
increased suddenly. After several meetings and many telephone
discussions between EPA, WASA and the Washington Aqueduct, in May 2003,
EPA acquired the services of Dr. Marc Edwards of Virginia Tech. Dr.
Edwards performed his investigations during the spring, summer and fall
of 2003. He presented his written report to EPA Region III in October
2003 and presented his findings to EPA, WASA and the Washington
Aqueduct in early November 2003. WASA then developed a research
strategy based on the recommendations of Dr. Edwards. This strategy,
which WASA has already begun to implement, was presented to the
Washington Aqueduct, their Virginia wholesale customers, and EPA in
January 2004.
The 2003 lead service line sampling data released by WASA in late
Fall, 2003 indicated that the high lead levels were a wide-spread
problem for homes with lead service lines. More research had to be
completed and a treatment solution found as quickly as possible. EPA,
WASA, WA and the D.C. Department of Health (DC DOH) recognized that an
overarching planning and coordination effort was needed to help ensure
that all the necessary research was conducted, to ensure no redundant
efforts took place and to move the work along as quickly as possible.
The Technical Expert Working Group (TEWG) was formed to facilitate and
expedite on-going research conducted by both WASA and the Washington
Aqueduct (WA) of the Army Corps of Engineers as well as research
already planned but not yet carried out. The Working Group's formation
took place well before work began on the compliance order.
EPA, WASA , WA and DC DOH first gathered on a teleconference on
February 5, 2004 to discuss the research plans in place in both WASA
and the Aqueduct. Another important purpose of the call was to develop
a listing of any further work that needed to take place to find a
treatment solution for re-optimizing the Aqueduct's optimal corrosion
control treatment (OCCT). It was decided on that teleconference that
the group should meet face to face to outline an overall strategy to
this research effort. Staff and contractors for WASA and the Aqueduct,
DC DOH, Arlington County and Falls Church Virginia, as well as EPA
staff members from the Mid-Atlantic Regional Office, EPA's Office of
Research and Development in Cincinnati, OH, and EPA's Office of Ground
Water and Drinking Water (OGWDW) and the Centers for Disease Control
and Prevention (CDC) gathered on the following Monday, February 9,
2004. The Group agreed to the strategy outline that formed the basis
for the Working Group's Action Plan as well as the Group's structure.
The Working Group's mission as a coordination and communications
facilitation group would also help hasten EPA's review and approval of
any treatment proposed by the WA and its wholesale customers. Since EPA
is involved directly in the Working Group, no time is lost in reviewing
research results and proposals after the fact. The Working Group will
cease to exist once the research in the Action Plan is completed and
corrosion control treatment is optimized. That should take place in the
first half of 2005.
EPA's OGWDW formed, through a contractor, an independent peer
review panel to review the work of the Technical Expert Working Group
and provide their recommendations for changes to research or treatment
selected. OGWDW identified a need to assemble a group of experts that
represented the engineering research community, water utilities and
state drinking water programs. OGWDW also specified that the experts
assembled would not have had direct experience in working on any
aspects of corrosion control treatment and lead corrosion in the
District of Columbia. This group was also formed to address the lead in
the District's tap water situation and is not permanent.

Response for the Record by Benjamin H. Grumbles, Acting Assistant
Administrator for Water, U.S. Environmental Protection Agency, to
Questions of Majority Members
Question 1) Your testimony states that the primary sources of lead
in drinking water are from lead pipe, brass plumbing fixtures
containing lead, and lead solder. You further state that ``setting a
standard for water leaving the treatment plant fails to capture the
extent of lead leaching in the distribution system and household
plumbing.'' Does this mean you do or do not believe that setting an MCL
for lead is appropriate and why?
Response: As the question notes, the primary source of lead is not
normally from the source water, but from household plumbing and/or lead
service lines connecting a house with the distribution system. The
actual level that is in any one house can vary significantly depending
on the plumbing and presence/absence of a lead service line. Under the
Safe Drinking Water Act (SDWA), EPA has determined that a public water
system cannot be held responsible for services outside of its control,
such as the plumbing within a house.
When setting a maximum contaminant level (MCL), EPA must identify a
level that is as close to the maximum contaminant level goal (MCLG) as
possible, but still feasible (based on use of best field-tested
technology/treatment techniques) and taking costs into consideration
(for a large system). In the 1988 proposal for the Lead and Copper
Rule, EPA indicated that following this could have led to an MCL as
high as 30-40 ppb, much higher than the MCLG of zero. EPA believed such
a level would represent unnecessarily high exposures for large segments
of the population.
The SDWA allows EPA to issue a regulation that requires the use of
a treatment technique in lieu of establishing an MCL if the
Administrator makes a finding that it is not economically or
technically feasible to identify the level of the contaminant. EPA
determined that a treatment technique that would reduce corrosion
within the distribution system would be more protective of public
health. By optimizing corrosion control treatment, a system would
reduce lead occurring as a byproduct of corrosion.
Question 2) Mr. Johnson's testimony argues that the District of
Columbia should be given primacy to run their drinking water program
under section 1413 of the Safe Drinking Water Act. In light of the
record of the past 4 years and a present lead action level that is four
times the legal limit, would you support giving D.C. that authority?
Response: Under the SDWA, the District of Columbia is included
within the definition of ``state'' and thus would be eligible to be
considered for primacy, provided that the District could satisfy the
criteria contained in 40 C.F.R. 142.10. Among those criteria, the
District must demonstrate that it can compel compliance with the
national primary drinking water regulations by all public water systems
in the District, and that it can take appropriate enforcement actions
to address any threatened or continuing violation of the national
primary drinking water regulations. The District of Columbia has not
made an application for primary enforcement responsibility to carry out
the drinking water program.
There are two public water suppliers in the District, the
Washington Aqueduct and the District of Columbia Water and Sewer
Authority (WASA). In 1977 and again in 1994, EPA communicated to the
District its concern that Section 602 (b) of the District of Columbia
Self-Governing and Governmental Reorganization Act of 1973 (the ``Home
Rule Act''), Pub. L. 93-198 (see also D.C. Code 1-206.02), may limit
the District's ability to adequately regulate the Washington Aqueduct.
EPA requested that the District inform EPA if the District believed
that the Home Rule Act did not present an impediment to primacy. EPA is
unaware of any relevant changes to this provision of the Home Rule Act
subsequent to 1994, and consequently, it remains necessary for the
District to demonstrate that the Home Rule Act does not present an
impediment to the District's regulation of the Washington Aqueduct.
In addition, in 1977 and 1994, EPA expressed concern that there
would be problems inherent in the regulation of one municipal
department by another, as authority over the water distribution system
was then vested in the District's Department of Public Works' Water and
Sewer Utility Administration (WASUA). Since 1994, the authorities of
WASUA have been transferred to WASA, which is a quasi-independent
authority of the District of Columbia. It is EPA's understanding that
the Mayor has power to appoint and remove WASA Board members. EPA is
not aware of any other authorities the Mayor or the District may have
with respect to oversight of WASA. Further research would be necessary
to determine whether the District has adequate authorities to regulate
WASA.
Question 3) Your testimony mentions that large water systems
serving more than 50,000 people were required to be compliant by
January 1, 1997 and that small and medium systems were supposed to
optimize corrosion control when tap monitoring requires it. Could you
please tell us about the status of compliance for all systems and
whether any challenges exist in getting systems into compliance?
Response: The Agency has not yet conducted a thorough national
review of corrosion control status, instead focusing on rule violations
and the 90th percentile levels. The Lead and Copper rule is unique, in
that states are not only required to report violations, but also the
numerical 90th percentile values. We believe that, by reviewing the
90th percentile values, we will be able to determine the effectiveness
of corrosion control. As noted in the testimony, as of June 1, 2004,
the Agency has results for close to 90 percent of the systems for which
the states are required to report data. The data indicated that fewer
than 4% of the systems had an exceedance reported during monitoring
periods ending after January 2000. In a subsequent report on the data
we have in our Safe Drinking Water System, we will be looking more
closely at violation trends and whether all systems subject to
requirements have optimized corrosion control.
As with all drinking water rules, some very small water systems may
still face challenges in optimizing corrosion control. Small systems
often lack sufficient resources to conduct a corrosion control study.
Others may lack adequate operator training to implement corrosion
control. As part of our review of state programs, we will investigate
whether systems are still challenged and the root causes for failure to
implement corrosion control, where needed.
Question 4a) In the section of your testimony that refers to the
``National Review of Compliance and Implementation of the Lead and
Copper Rule,'' you mention a focus on the Safe Drinking Water
Information System (SDWIS). How complete is your SDWIS database and
what types of information gaps exist?
Response: EPA has made significant strides in improving data
quality since its first data quality assessment in 1999. The Agency has
worked with states to develop strategies to improve the completeness
and accuracy of data. As we saw in this case, the completeness of data
is critical--EPA had 90th percentile data from only 23% of the systems
required to report such data in March 2004 when this issue first arose.
Since that time states have made a concerted effort to enter data, such
that we now have data from more than 90% of the systems that are
required to report. EPA is continuing to work with the states to ensure
that data for every system required to report is in SDWIS and that all
data that should have been submitted by each system is also present.
When reporting on our drinking water goals, we have always tried to
be clear that there are issues with data quality. The data that we
receive from states is the most robust set of national data that we
have on drinking water compliance. EPA is committed to continuing to
work with states to improve the quality of the data we use in carrying
out our programs and reporting to the public.
Question 4b) You mention that 89 percent of medium and large water
systems have reported their data. How solid a percentage is the 89
percent and who has not reported their data?
Response: EPA's summary of data in SDWIS as of June 1, 2004,
indicated that there were no data for 90 large systems (out of 834) and
875 medium systems (out of 7,833). Seventy of the systems for which EPA
did not have data were from the State of California. The Agency is
working with the state to ensure that data are made available. It is
also important to note that some of the systems with no data are part
of consecutive systems where the wholesaler/purchaser is responsible
for reporting the results of monitoring. EPA verified that 19 of the 20
remaining large systems without data were part of a consecutive system
which reported on their behalf, but did not attempt to verify that fact
for the medium systems (due to the number). EPA has asked states to
indicate which systems have reporting included under another system and
will present that information in its next summary of the data.
Question 4c) How many of the 88 water utilities that reported
exceeded lead action level are chronic offenders and what is EPA
specifically doing about it?
Response: Exceeding the action level, in and of itself, does not
make one an ``offender.'' A violation is only assessed if a system
fails to take the actions outlined by the rule, such as carrying out
public education and implementing corrosion control treatment. States
have primary enforcement responsibility for carrying out the lead and
copper rule (EPA only has this responsibility for the District and
Wyoming). EPA followed up with several states to inquire about their
activities with large systems exceeding the action level during 2003.
In some cases, more recent monitoring showed that the system had been
able to get back below the action level. In other cases, the state is
working with the system to understand the cause of elevated levels
(e.g., treatment changes, malfunctioning equipment) or to see that they
develop and implement lead service line replacement programs.
EPA is currently reviewing implementation of the lead and copper
rule in several states. As part of this review, the Agency will
evaluate how states work with systems that exceed the action level and
how they are carrying out enforcement against those systems that fail
to take the required actions.
Question 5) GAO testified that more funding in the SRF would not
have made a difference in the outcome of the current DC lead situation.
Do you agree with this assessment?
Response: I agree with GAO's assessment on this issue. The lead
problem was caused by a failure to adequately control corrosion within
the distribution system, not inadequate DWSRF monies. Prior to
discovery of the lead problem, WASA had a capital improvement plan that
did not include lead service line replacement. Now that the problem has
been identified, WASA intends to use DWSRF funding for this purpose and
recently received $8.4 million in DWSRF funding to address two separate
contracts for lead service line replacement. However, even if WASA were
to replace all lead service lines, in-line fixtures, fittings and
solder could still leach lead if corrosion control is not effective.
Question 6a) Help me to understand the funding priorities of the
Bush Administration as articulated in its budget requests for the
drinking water revolving loan fund. Is it correct that the first fiscal
year that President Bush was in office, fiscal year 2001, the EPA
budget for the drinking water revolving loan fund had been proposed by
the Clinton Administration?
Response: Yes, the FY 2001 budget, for the fiscal year beginning in
October 2000, was proposed by the Clinton Administration in February
2000.
Question 6b) Is it accurate to state that, since the fiscal year
2002 budget request needed to be submitted to Congress shortly after
the presidential inauguration in 2001, the Bush Administration did not
have appropriate time to review and submit its own fiscal year 2002
budget request for the drinking water revolving loan fund program and
instead a ``transition'' budget that recommended the previous fiscal
year's level of funding was submitted to Congress?
Response: In the case of the DWSRF program, the 2001 budget request
was $825 million, however, the amount appropriated was $823.2 million
(due to a rescission of funds). The FY 2002 budget request was $823.2
million, the same amount appropriated by Congress in FY 2001.
Question 6c) Is it correct to suggest that the first ``real'' Bush
Administration budget request for the drinking water revolving loan
fund program did not occur until the fiscal year 2003 proposal?
Response: It is correct that the first complete budget developed by
the Bush Administration was developed during 2001 and submitted to
Congress in February 2002 for the federal funding year commencing on
October 1, 2003.
Question 6d) What did the Bush Administration request for fiscal
years 2003-2005 for the drinking water revolving loan fund program?
Response: The President's Budget has requested $850 million for the
DWSRF for each year between 2003 and 2005. The actual amounts
appropriated ($844.5 in FY03 and $845 million in FY04) were less than
the President's request.
Question 6e) Were the budget requests, proposed for any fiscal year
by the Clinton Administration, for the drinking water revolving loan
fund equal to or greater than those made by the Bush Administration for
the drinking water revolving loan fund?
Response: None of the budget requests proposed for the DWSRF
program under the Clinton Administration were equal to or greater than
$850 million.
Question 7a) Many people are concerned about the aging water
infrastructure in our country. In fact, EPA in 1997 and 2001 published
need survey reports that pegged certain figures for what utilities
mentioned would be financially necessary. Could you please comment on
what figures the Administration supports for future water
infrastructure and drinking water delivery system funding and when you
envision the next needs report to come to Congress?
Response: The Administration has committed to fund the DWSRF
program at $850 million per year through 2018. Our next Needs Survey
report is due to Congress in February 2005. We cannot provide any
information on the results of the survey at this time as it is still
undergoing evaluation. I fully expect that we will complete the report
on time, as has been the case with the previous reports.
Question 7b) Does EPA consider wastewater and drinking water
protection essential to securing public health?
Response: Yes. The availability of clean and safe water is
essential to public health and the environment. It also facilitates
business investment and allows us to travel freely across our nation,
for employment and recreation, while having confidence that the water
resources we depend on will be safe wherever we travel.
Question 7c) Also, with respect to the funding gap for water
infrastructure, do you believe activities that fall under your
sustainable infrastructure initiative would actually help to buy down
costs?
Response: I do. In the area of better management, Government
Accountability Office release a report earlier this year on asset
management that provided several examples of how utilities have
achieved cost savings through better management of their
infrastructure. When managers better understand the condition of their
assets, they are able to make more informed decisions about whether to
replace or rehabilitate infrastructure. For example, Louisville used a
pipe evaluation model to determine whether pipes should be replaced or
rehabilitated. Their analysis identified that a certain vintage of
pipes that were as old as one hundred years were still reliable and not
subject to as many breaks as other pipe that was younger. Rather than
replace the older pipes just because they were old, the utility
rehabilitated them by lining them with cement, which will increase
their useful life by another 40 years.
It is not just large systems that can benefit from these types of
activities. With respect to water efficiency, one of EPA's reports
described a small water system serving 2,000 people in Pennsylvania.
Seventy percent of the water produced by the system was unaccounted for
due to leaks. After implementing a leak detection program, unaccounted
for water decreased to only 9 percent. This translated into real cost
savings for the utility--costs for chemicals to treat the water
decreased almost 50% and energy costs decreased close to 60%. The
utility also expects its equipment to last longer since they have been
able to reduce plant production hours.

Response for the Record by Donald Welsh, Regional Administrator, U.S.
Environmental Protection Agency, to Questions of Minority Members
CONGRESSMAN DINGELL
Question 1) I understand from EPA staff that sampling has been
conducted in your region which indicates that so called ``lead free''
materials are leaching enough lead to cause exceedances in action
levels. Please provide us with those results.
Response: DC WASA has results from more than 20,000 sample results
collected from homes within the District. Many first draw samples from
homes, which generally represent the water that has sat in the faucet
and pipes immediately behind the faucet, exceeded the 15 ppb lead
action level. However, there is no way to tell which of these homes
have faucets and fixtures that were manufactured after the SDWA set the
current lead-free standard that fixtures and fittings contain no more
than eight percent lead.
The District of Columbia Water and Sewer Authority performed some
very limited testing on relatively new water meters with brass casings.
While, WASA has briefly discussed the results with EPA staff by
telephone, the Agency does not yet have the Authority's full report on
the study and therefore cannot evaluate the results. We would recommend
that the Committee contact WASA to obtain any information about the
study.
Question 2) Given the criticisms EPA received as a result of the
drinking water crisis in the District of Columbia, have you made any
changes at the regional level in terms of management oversight?
Response: EPA Region III has modified the manner in which
compliance data from WASA and the Aqueduct is handled. Reports from
both utilities are now sent to the office responsible for Safe Drinking
Water Act enforcement. That office, in consultation with the drinking
water program experts, will make compliance determinations. This
process ensures that a team of EPA staff, including enforcement,
regulatory, and programmatic experts, will see each compliance report.
In addition, Region III developed a report entitled Recommendations
for Improving the Washington DC Water and Sewer Authority Lead in
Drinking Water Public Education Program. The report was prepared by a
team of EPA staff and managers from Region III, Headquarters and Region
I. Participants in the review had expertise in topics including
drinking water technical and regulatory issues, as well as outreach,
education and risk communication. The purpose of this report is to
present the findings of the evaluation of the education and outreach
activities carried out by the Washington DC Water and Sewer Authority
in response to elevated levels of lead in the District's drinking water
during 2002 and 2003.
In order to fully ensure a more effective communications program in
the future, EPA will also have to make some improvements in its own
efforts. In addition to steps that EPA has already taken, such as
issuing new Standard Operating Procedures to ensure timely and thorough
review of all reports and materials, the review team has suggested
several actions below to be considered by EPA Region 3, most of which
are being implemented at this time:
When an Action Level is exceeded, ensure that the water provider is
in possession of the EPA guidance document, and strongly
encourage the use of that document.
Set milestones for public outreach and education and assure that all
milestones are met on schedule.
Obtain written agreement from WASA to receive drafts of education
materials, and a timeline for their submission. Review these
drafts for compliance with requirements, as well as
effectiveness of materials and delivery. This review should not
delay notifications to the affected public.
Determine criteria and measures for evaluation in order to determine
if outreach efforts have been effective.
Institute an internal process that ensures that materials are
reviewed in a timely manner by a team consisting of staff with
technical, compliance and outreach expertise. The process
should also ensure that management is immediately alerted to
issues of concern.
When a lead Action Level is exceeded, acquire outside expertise to
assist in evaluating outreach efforts.
CONGRESSWOMAN SOLIS
Question 1) Your testimony noted that EPA directed WASA and
Washington, D.C. to expedite notification to customers of the results
of water sampling at their residences. You also noted that more than
32,000 filters and consumer instructions were sent to occupants in
homes with lead service lines. Can you please specify what specific
efforts the EPA took to communicate and cooperate with the
traditionally underserved communities in Washington, D.C.? What form
did the publication notification system take and what languages was the
notification provided in? How does the notification system in
Washington, D.C. differ from that in Boston and Portland? What
oversight has the EPA exercised regarding public notification and to
what extent do Boston's and Portland's notification efforts exceed that
required by the regulations and suggested by the guidance?
Response: Initially, EPA required that DC WASA follow notification
requirements of the Lead and Copper Rule which includes developing and
providing public education materials to significant populations of non-
English speaking peoples. On April 30, 2004, EPA issued a report that
made recommendations to DC WASA to take specific actions that are above
and beyond the requirements of the regulations. This report,
Recommendations for Improving the Washington DC Water and Sewer
Authority Lead in Drinking Water Public Education Program, outlined
steps DC WASA could take to improve their public education efforts
including: hiring internal or consultant expertise in areas of
marketing research and risk communication; conducting an internal
communications audit; developing strategic communications plans;
including stakeholders in decision making and forming a stakeholder
advisory group; and developing a plan to measure effectiveness of their
outreach efforts, including efforts to non-English speaking populations
in the District.
DC WASA's outreach documents related to lead in drinking water have
been provided in English and Spanish and have also included statements
in Chinese and Korean to explain the significance of the reports and to
provide information on how to obtain translated copies. The annual
Water Quality Report (a.k.a. Consumer Confidence Report) is also
published in Spanish.
The Administrative Order on consent, issued on June 17, 2004
required DCWASA to develop and submit to EPA a public education plan
that would address the recommendations of the above-mentioned report.
EPA also required DCWASA to notify their customers of results from
samples taken from their homes within three days of receiving the
results from the laboratory and to make best efforts to provide
customers with results from their tap samples within thirty days.
EPA Region III has not been able to determine the extent of both
Boston's and Portland's public outreach efforts for lead in drinking
water, but is attempting to gather that information from EPA Regions 1
and 10, respectively. Representatives from the Portland and Boston
utilities will be attending EPA's Expert Workshop on Public Education
for the Lead and Copper Rule on September 14-15 in Philadelphia and
will be able to share their experiences with EPA. We have gathered some
information indicating that Boston and Portland have attempted to
follow some of EPA's public education recommendations in our guidance
manual. Portland has made lead fact sheets available in four languages
on their Internet site. Also, additional public education was
incorporated into a comprehensive citywide lead hazard reduction
program.
Boston's public education program was carried by the Massachusetts
Water Resources Authority (MWRA) which supplies water to Boston and 27
other municipalities. MWRA has lead information on their Internet site,
but none of it is specific to any one municipality. There are no
foreign language versions of documents on their Internet site and no
description of their outreach program. MWRA's Water Quality Report from
2003 states in many different languages that the report has important
information about their drinking water and suggests that the customers
translate the document themselves or get someone else to translate it
for them.
The responsibility for informing the public of violations or water
contamination falls directly to the water utilities. EPA has taken the
above-mentioned steps to ensure that DC WASA reaches all community
members, including under-served communities and non-English speaking
populations. EPA's own efforts in carrying out outreach to the
community have included development of fact sheets and brochures in
Spanish, production of public service announcements for radio broadcast
in Spanish, and provision of a translator at a public meeting that was
likely to have Spanish speakers in attendance. The Agency has also
convened public meetings in predominantly minority areas of the
District.
Question 2) To what extent is it your policy to provide public
notification of water contamination where English is not the primary
written or spoken language?
Response: EPA's policy and regulations require that water utilities
take steps to ensure that any significant populations of non-English
speaking customers receive information about their water in the
appropriate language. This includes the Lead and Copper Rule public
education requirements as well as our Public Notification requirements
for informing the public about violations of the SDWA as well as the
Consumer Confidence Report requirements. For water utilities serving a
large proportion of non-English speaking consumers, the water system
must include in the public notice information in the appropriate
language or languages regarding the importance of the notice or include
a telephone number or address where persons served may contact the
water system to obtain a translated copy of the notice or to request
assistance in the appropriate language.

Response for the Record by Benjamin H. Grumbles, Acting Assistant
Administrator for Water, U.S. Environmental Protection Agency, to
Questions of Minority Members
CONGRESSMAN DINGELL
Question 1a) In your testimony, you indicated that you have written
letters to State Directors of Health and Environmental Agencies seeking
information on state and local efforts to monitor for lead in schools.
You also indicated that ``[g]enerally, states responded that they
implemented the requirements associated with the [Lead Contamination
Control Act]'' and that ``[m]ost states agreed that minimizing lead in
drinking water consumed by children is important...'' (Emphasis added).
Please explain why it was necessary to qualify these statements and
which states did not fully agree with or confirm these principles.
Response: EPA did not send an explicit survey instrument to states.
Therefore, as noted in the report made available on EPA's website, the
responses we received were varied. Most states gave details about how
they had implemented the Lead Contamination Control Act (LCCA).
However, one should not assume that if a state did not describe how it
implemented the LCCA, that it took no actions to do so. Likewise, if a
state did not explicitly express support for minimizing lead in
drinking water consumed by children within their letter, one should not
assume that they have no interest in doing so. In writing the report,
we wanted to be sure that we were precise. Had EPA failed to qualify
the statements, the Agency could have been criticized for making the
statements when some states did not expressly state that fact within
their responses.
Question 1b) Is EPA taking any action, other than this survey and
reviews of guidance, to address lead contamination issues in schools
and daycare centers, including revising sampling requirements so that
more testing will occur in these locations?
Response: First, we are working with states to ensure that schools
and day care facilities that operate their own public water systems
have appropriate guidance in hand to understand the regulations. We are
also working with other children's health programs within EPA to
include information on issues associated with school drinking water in
existing initiatives such as the ``Tools for Schools'' program.
We are working with the American Water Works Association and other
stakeholders to encourage utilities to develop voluntary testing
program partnerships with schools within their service areas. Finally,
we are planning to host a meeting this fall to discuss school and day
care facility drinking water issues. The Agency looks forward to
working collaboratively with states, other offices within EPA, other
federal agencies and members of this committee to carry out these
actions and others that will help communities improve voluntary school
drinking water testing programs.
As to whether the monitoring requirements should be modified to
allow for more testing of schools and day care facilities, EPA will
have to evaluate this as part of its review of the existing
requirements. The purpose of the tap monitoring is to determine the
overall corrosivity of the treated water using worst-case lead sample
site data as an indicator of the effectiveness of the system's
corrosion control treatment. It is not designed to measure the health
risks to individual consumers.
Question 2a) In your testimony, you indicated that EPA is
conducting a national review of compliance and implementation of the
lead and copper rule. How long do you estimate it will take to complete
the review and recommendations?
Response: We expect to complete our review in the first half of
2005. Currently we are working to ensure that we have all available
data on 90th percentile levels, violations and enforcement actions that
have occurred in the last several years. Within the next month we will
release an update to the previous report released in late June 2004.
We have developed a plan to evaluate implementation of the rule at
the state and system level. Our efforts will be aimed at understanding
how the rule has been implemented nationwide, and ensuring that systems
are conducting required monitoring in accordance with the rule and that
follow-up actions required in the case that an action level is exceeded
are being fully and effectively implemented. This detailed look will
also help to identify areas where further training or guidance is
needed. EPA currently plans to visit 10 states, one in each EPA region,
between August and December 2004. Five of the states are states that
EPA had already planned to visit as part of its on-going data
verification reviews (Texas, Virginia, Utah, Illinois, and
Massachusetts). EPA will also be visiting California, New Jersey,
Oregon, Iowa, and Georgia.
We will also be reviewing the actions taken by utilities who had
exceeded the action level in the 1991/92 testing timeframe to determine
if the actions required by the rule have helped them to reduce
corrosion and lead levels at customer taps. Effectiveness will also be
judged through the review we will be conducting of state and system
implementation.
Question 2b) Please describe which additional recommendations on
public communications are included in or under consideration for the
guidance that are not specified in the rule.
Response: The existing Public Education Guidance discusses
additional actions that are not specified in the rule, including
developing action plans, community-based task forces, water testing
programs, and public education materials. Additional potential areas
for consideration include varying public education language or the
frequency of delivery based on the levels of exceedance, mandating
notification of homeowners when test results show elevated lead levels,
and evaluating the flushing guidelines to address site specific
characteristics. The expert workshop on publication education
requirement under the Lead and Copper Rule that EPA is convening on
September 14-15 in Philadelphia should elicit additional ideas.
Question 2c) Given the critical importance of public communication
when, under the lead and copper rule, high lead levels are allowed to
remain in drinking water for extended periods of time, why does not EPA
require as oppose to simply recommend effective public communication
strategies now?
Response: The existing regulation requires that water systems
communicate repeatedly with their customers as long as they are
exceeding the action level and provides specific requirements as to how
this is to be achieved, such as, for example, the types of audiences
they must reach. EPA's public education guidance provides additional
recommendations for activities that water systems may want to undertake
to create more robust communication programs. EPA expects that it will
identify additional best practices at its public education workshop in
September. However, in order to require systems to take any of the
actions identified in the guidance or through the workshop, EPA would
have to make revisions to the existing regulations, which would take
time. EPA will continue to strongly encourage water systems to take the
actions appropriate to their situation to ensure that the public is
well informed about all issues relating to the safety of their drinking
water.
Question 3) EPA currently requires the same number of samples, 100,
in certain cases, whether a city has a population of 100,000 or 7
million. Please provide a justification for the conclusion that this
sampling approach is adequate for cities at the low and high end of
this range. If the sampling protocols are not representative, how do we
know precisely how much progress we are making on lead contamination
nationwide?
Response: The rule requires each system to develop a sampling plan
that is focused on the highest-risk areas (lead service lines, lead
piping, lead solder less than 5 years old). A set of 50 or 100 samples
should be enough to define the problem, as was the case in the
District.
During development of the rule, an analysis was undertaken to
determine if the number of sampling locations identified in the rule
would be sufficient to identify action level exceedances. The analysis
was based on those used in private industry to evaluate quality control
applications or estimate the fraction of a population of products that
is defective or exceeds an acceptable standard. While the analysis was
based on an assumption that sample locations would be randomly
selected, the rule requires targeting towards high-risk sites (i.e.,
worst case). The analysis indicated that there was high confidence that
systems which exceeded the action level would be correctly identified
as such by collecting the minimum number of samples identified in the
rule, confidence that is increased because the rule requires targeted
sampling rather than random.
Water utilities have expressed to us that one of the greatest
challenges they face in implementing the lead and copper rule is
identifying a sufficient number of sites that can be maintained for
sampling over the long-term. In considering this issue, we need to
ensure that we don't trade off quality for quantity. We may need to
consider other sampling models that will help utilities better
understand whether their corrosion control treatment is effectively
managing lead levels.
Question 4) One of the problems with the lead and copper rule that
appears ripe for a solution is that a drinking water system can test
repeatedly to look for lead lines that are not leaching and can use
those lines that are found not to leach for credit so that they can
avoid replacing the lines that are actually leaching. This unfortunate
approach provides exactly the wrong incentive to the drinking water
systems and does not protect public health. Please indicate what steps
are being taken to immediately address this problem.
Response: Monitoring the lead service lines is a way to quickly
determine the areas of greatest risk If a service line is not leaching
lead, there is no need to replace it. The requirement to replace 7% of
the lines every year was intended to give systems enough time to get
financing for, and physically replace lead service lines. I do not
believe that EPA contemplated that systems would test more than 7% of
their lines every year to avoid the need to physically replace lines.
This practice poses a concern to EPA because it could allow a
system to push off the replacement of the lines that are posing the
greatest risk. EPA will be reviewing how states and utilities have been
implementing this provision to see if D.C. is unique or the norm. We
will also address this during our lead service line replacement
workshop that has been scheduled for the end of October. The rule
provides that the state shall require a shorter schedule for lead line
replacement where a shorter schedule is feasible, which could be the
case if a significant number of lines tested below the action level. We
may have to work with states to ensure that physical replacement of
lines that show elevated lead concentrations is a priority.
Question 5) Does EPA support a review of and changes to the ``lead
free'' designation for materials with 8% of lead or less? What
information do you have to indicate that this standard is or is not
protective?
Response: The provision defining ``lead-free'' at 8% is in the SDWA
and the Agency has heard interest in seeing that number reduced. Many
participants at the expert workshops we held in St. Louis in mid-May
expressed interest in decreasing the allowable amount of lead in
fixtures that are in contact with drinking water. It is the Agency's
understanding that, while the amount of lead in a product is governed
by the manufacturing process, truly lead-free products are available--
although they may carry a slightly higher cost. The Agency is bound to
some extent by the language in the statute, however, we may work with
the NSF and other stakeholders to address the voluntary standard that
determines the allowable amount of lead that can be leached from
fixtures and also work more closely with industry to encourage them to
reduce the amount of lead in fixtures.
Question 6a) At the hearing, you were asked for definite time lines
for a proposed MCL for perchlorate. In response, you testified that
``We want to make sure we get the science right and do it as quickly as
possible. We are expecting to get the NAS report in January.'' Please
provide a summary of the scientific research efforts that the EPA has
undertaken for perchlorate. When did EPA first initiate its research
efforts?
Response: The Agency is currently in the process of updating a
table which describes research efforts undertaken by EPA. We will
provide this table to the Committee when it is completed.
Question 6b) Please indicate whether any of the EPA studies or
research results have been submitted to the EPA Science Advisory Board
(SAB). If so, please indicate the dates of submission to the SAB and
the results of their review.
Response: To date, EPA has not submitted studies or research
results to the SAB and the current evaluation of perchlorate research
by the National Academy of Sciences obviates the need for review by the
SAB. While a subsequent review could be requested, it would appear
duplicative and entail a significant amount of time to review the data.
Question 6c) Further, after receiving the NAS report in January
2005, please indicate the date when the EPA could first propose a
maximum contaminant level for perchlorate under the procedures of the
SDWA?
Response: EPA intends to act quickly in response to the NAS report
on perchlorate risk. However, it is difficult to speculate upon the
timing because we do not know what the NAS panel will conclude about
perchlorate risk, or what, if any, additional analyses may be
recommended by the panel. Assuming a best case scenario, that the NAS
report contains sufficient information and recommendations to support
EPA's efforts, the earliest date by which a national primary drinking
water regulation for perchlorate could be proposed is April, 2007.
Because the NAS Panel report is critical to EPA's ability to make a
number of determinations that are needed prior to making a decision to
regulate perchlorate, it will first undergo a thorough review by Agency
scientists. Under the SDWA, EPA is required to determine that:
the contaminant may have an adverse health effect,
the contaminant is known to occur or there is a substantial
likelihood that the contaminant will occur in public water
systems with a frequency and at levels of public health
concern, and
regulation of the contaminant presents a meaningful opportunity for
health risk reduction.
If the information in the report is sufficient to make a
determination to regulate perchlorate, the SDWA also requires that the
Agency prepare a health risk reduction cost analysis (HRRCA) to support
the proposed regulation. The HRRCA analysis must include an estimate of
benefits and costs (both quantifiable and non-quantifiable) as well as
an evaluation of the effects of the contaminant on the general
population and on sensitive subpopulations. Because the HRRCA is based,
in large part, on the conclusions of the NAS report, it is difficult to
estimate the time required to prepare the HRRCA analysis and have it
reviewed to insure its soundness without knowing the outcome of the
panel's review.
It is important to note that EPA is not sitting idle while the risk
assessments undergoes NAS review. The Agency is collecting data on
contaminant occurrence through the Unregulated Contaminant Monitoring
Rule, is improving analytical methods to enable detection of
perchlorate in water at lower concentrations, and is investigating
treatment technologies that could remove perchlorate from drinking
water. These important activities will help the Agency make a
scientifically sound determination whether to initiate a rule-making
process for perchlorate in drinking water.
CONGRESSWOMAN SOLIS
Question 1) On April 12, 2004, Mr. Dingell and I wrote to
Administrator Leavitt and asked why President Bush's budget for FY 2004
did not contain any funding to implement the New York Watershed Program
(part of the Safe Drinking Water Act). While the written response we
received acknowledged that the Bush Administration did not seek funding
for the program, it did not answer why funding was not included. As
Acting Administrator, can you explain why the President's budget in FY
2005 did not seek funding for the New York Watershed program?
Response: Funding for the New York Watershed program was not
requested by either the Bush or Clinton Administrations. Congress
provided an earmark for this program through the appropriations
process. While the Agency supports the NYC Watershed Protection
program, federal funding decisions must be made within the context of
national priorities that are both internal and external to EPA. The
primary funding priorities for the national water program are the State
Revolving Fund programs. It is important to note that the NYC Watershed
program has benefitted from the state's Clean Water State Revolving
Fund program. Assistance from the CWSRF can be used to fund activities
which include land acquisition and conservation easements that promote
water quality improvements and construction of centralized treatment to
replace septic systems. The Administration has committed to fund the
CWSRF at a level of $850 million per year through 2011. New York has
used more than $2.3 billion in federal CWSRF grants to help finance
more than $6.4 billion in water quality projects since 1987, with more
than $608 million provided in state fiscal year 2003 alone.
Question 2) In testimony on behalf of the American Water Works
Association (AWWA), Mr . Lynn Stovall stated that there is a gap
between current levels of investment and levels of investment required
to sustain adequate drinking water service. Mr. Stovall testified that
this gap is approaching $300 billion above and beyond what utilities
are already spending to sustain adequate drinking water service. Do you
agree with AWWA's figure? If not, what gap has the EPA identified?
Response: Several organizations, including the AWWA, a utility-
supported Water Infrastructure Network, and the Congressional Budget
Office, have developed estimates of the gap. EPA's Clean Water and
Drinking Water Infrastructure Gap Analysis, released in October 2002,
provided a range of estimates, which reflect the hundreds of different
scenarios that could be used to forecast needs and spending. The ranges
included estimates that were consistent with values identified by the
organizations mentioned above.
EPA's report provided a 20-year capital gap point estimate $102
billion for drinking water. EPA also estimated that gap that would
result under a growth scenario that forecasted utility revenue
increases at a real rate of 3 percent per year, consistent with
economic growth forecasts in the President's budget. Under the growth
scenario, the point estimate for the drinking water capital gap $45
billion.
Question 3) When you appeared two years ago before this
subcommittee, members pointed out the President's budget request was
$150 million less than Congress authorized in the 1996 Safe Drinking
Water Act Amendments. The President's FY 2005 request is still only
$850 million. Two years ago you responded that ``we very much welcome
constructive dialogue with members of the authorizing committee
regarding authorization levels.'' Have you had any dialogue with
members of the authorizing committee regarding authorization levels?
Please describe the dialogue and any action that has been taken by the
EPA in response, with respect to authorization levels.
Response: The Agency has never recommended specific authorization
levels for the State Revolving Fund (SRF) programs. However, EPA has
provided technical assistance, upon request, to staff from the Senate
Environment and Public Works committee as they developed SRF
reauthorization bills (S. 1961 in 2002 and S. 2550 in 2004). Upon
request, the Agency has provided information to staff on the potential
revolving levels that would result at different authorization levels
posed by committee staff. The revolving level is the estimated annual
assistance that will result in out years (generally a 20 year period
beginning 2-3 years after capitalization ends) from an assumed period
and dollar amount of capitalization. The Agency has also briefed House
Commerce Committee staff on the Needs Survey, Gap Analysis, and status
of the DWSRF program.
While the Administration does not support the authorization levels
that have been included in the bills before Congress, it does support
the SRF program framework. In the 2003 President's Budget, the
Administration committed to fund the Drinking Water SRF program at its
current annual $850 million level through 2018. This decision was
based, in part, on feedback from Congress and stakeholders on the
important role that the DWSRF plays in helping water utilities maintain
compliance with the Safe Drinking Water Act.
Question 4a) A recent press story referenced a ``Bush science
advisor'' having stated the Defense Department lobbied the EPA to delay
implementation of a perchlorate standard. What communications has the
EPA had with the Defense Department regarding establishing a
perchlorate standard, both prior to and since the decision to defer
implementation of a perchlorate standard?
Response: The Office of Water has not had any discussions with the
Defense Department (DoD) related to deferring development of a drinking
water standard and thus cannot confirm DoD lobbying efforts. The Agency
has had discussions with the DoD on issues related to research and has
reviewed DoD material as part of the intergovernmental review process
managed by OMB. EPA, NASA and DoD jointly requested a comprehensive NAS
review of the underlying science for the EPA health risk assessment.
Question 4b) Has the EPA had any communication with the NAS,
regarding the conflict of interest controversy on their perchlorate
panel?
Response: EPA's Office of Research and Development has been the
Agency focal point for communication with NAS. EPA has not communicated
with the NAS since the original selection of the perchlorate panel.
Question 5a) The U.S. Food and Drug Administration is conducting a
series of ``high-priority'' perchlorate tests this summer to gauge the
extent of perchlorate in the food supply. Has the EPA conducted similar
tests to gauge the extent of contamination of the water supply caused
by the use of perchlorate by private industry or military contractors?
Response: Under the Unregulated Contaminant Monitoring Rule (UCMR),
EPA has sampled 800 representative small public water systems serving
less than 10,000 people and required data from all of the large public
water systems for the past three years. As of May 2004, 3,147 public
water systems (2,400 large and 797 small) have reported their
perchlorate monitoring results. Perchlorate occurrence has been
reported at 131, or 4%, of these public water systems (123 large and 8
small) in 22 states and 1 territory. Only 2%, or 536, of the more than
23,000 samples analyzed have demonstrated positive results above the 4
ppb analytical method reporting level. The average value is 9.84 ppb
with a median value of 6.41 ppb using ion chromatography (method
314.0). The two highest levels were reported at a public water system
in Puerto Rico (Utuado Urbano at 420 ppb) and Florida (Atlantic Beach
at 200 ppb). EPA will release a report of its results of UCMR
monitoring later this year.
Question 5b) Is the EPA working with the U.S. FDA to identify those
areas where water contamination is linked to food contamination? If
not, why not? If yes, please identify the extent of communication and
location of joint tests.
Response: EPA worked with the U.S. Department of Agriculture and
the University of Arizona on its testing of crops from 2002-2004 in the
Coachilla and Imperial Valleys contaminated by irrigation water from
the Colorado River downstream from Lake Mead. In a follow-up study, FDA
is currently examining 500 bottled water, milk and food samples as part
of the effort they initiated last fall. EPA continues to have contact
with USDA and FDA, but neither has required EPA identification of areas
of contamination, those areas being well known.
Question 6) In your testimony you highlighted that reducing lead
exposure is one of the EPA's priorities. What specific communications
or joint activities do you engage in regularly within the EPA or with
other organizations including the Centers for Disease Control (CDC) to
comprehensively combat lead exposures since January 2001? Please
describe how lead exposure levels have been reduced as a result of
these activities.
Response: In the mid-1990's, nearly 1 million children in the US
had blood lead levels exceeding the CDC level of concern of 10
micrograms per deciliter, which through the work of many has now been
reduced to 425,000. It is the goal of the federal agencies working on
lead poisoning prevention (EPA, CDC, and HUD) to reduce the number of
children with elevated blood lead levels down to zero by the year 2010.
Most of the Agency's activities related to childhood lead poisoning
prevention are managed out of the National Program Chemicals Division
in EPA's Office of Pollution Prevention and Toxics. EPA participates in
several collaborative efforts with other Federal agencies and state,
local and tribal governments to help carry out the mission to reduce
childhood lead poisoning in the U.S. The Agency has also devoted a
great deal of resources on public education and outreach to help build
awareness and prevent childhood poisoning. A detailed listing of
collaborative efforts and outreach activities is included in Attachment
1 to this response.
Attachment 1
EPA ACTIVITIES RELATED TO REDUCING CHILDHOOD LEAD POISONING
Collaboration Efforts
Federal Interagency Lead-Based Paint Task Force Meetings. EPA and HUD
serve as co-chairs for the Task Force. It is comprised
exclusively of participants from approximately 20 departments
or agencies, including CDC, CPSC, DOE, US Army, US Navy and
other Federal Agencies (held 3 times/year, last meeting June 3,
2004 , upcoming meeting October 2004)
National Lead & Healthy Homes Grantee Conference (sponsored by EPA,
HUD, and CDC for the grantees of the 3 federal agencies (State,
Tribal, and Territorial) to evaluate lead program successes and
plan for future; June 20-23, 2004 and June 9-12, 2003.
National Tribal Conference on Environmental Management (sponsored by
EPA to discuss environmental hazards in Indian Country. Special
sessions were held on lead education, May 9-11, 2000, held
every 4-5 years, upcoming meeting June 2005)
National Lead Health Education Conference (sponsored by EPA, CDC,
ATSDR, and HUD to discuss critical lead education information
and develop skills to strengthen education efforts in childhood
lead poisoning prevention programs nationwide; February 11-14,
2002, held every 4-5 years)
Forum on State and Tribal Action (FOSTTA), Subcommittee on Tribal
Affairs Project. (Provides a forum for Tribes and EPA to
discuss toxic substance issues, including lead, and to improve
communication among EPA and Tribes; meets quarterly with
monthly conference calls, last meeting June 29-30, 2004,
upcoming meeting October 2004)
National Lead Poisoning Prevention Week Observance (EPA joins the
District of Columbia's Department of Health to educate parents
and children on lead poisoning prevention thru heath fairs and
various activities during the week; October 19-25, 2003,
October 20-26, 2002, upcoming October 24-30, 2004)
Collaboration between EPA and CDC on analysis of NHANES data as it
relates to children's blood lead levels. In particular, EPA,
CDC, and HUD are currently drafting an article on the
Prevalence and Trends (1999-2002) in Blood Lead Levels Among US
Children and Adults.
EPA serves as a liaison member of the Department of Health and Human
Services Centers for Disease Control and Prevention's Advisory
Committee on Childhood Lead Poisoning Prevention. EPA attended
the last meeting in March 2004, and will attend the next
meeting in October 2004.
Public Outreach and Education
The National Head Start Association (NHSA) Campaign was initiated at
the NHSA's National conference in Anaheim, CA, April 2004. The
campaign provides the Head Start Center Director, staff, and
parents with customized informational fact sheets, a brochure,
and teaching curriculum on lead poisoning prevention.
The National Lead Information Center (NLIC), is a toll-free hotline
that answers questions (in English and Spanish) about lead and
distributes printed Agency information. The NLIC receives an
average of 60,000 contacts with the public each year.
The Women, Children, and Infants (WIC) Campaign worked with
nutritionists and other staff to disseminate lead poisoning
prevention information to WIC participants. The information
included fact sheets about lead and nutrition, medical
considerations, and lead hazards in the home. (November 2001)
EPA worked with the White House to develop the Keep Your MVP in the
Game Campaign. This campaign, which featured President Bush
with a Little League player and warned that ``Lead poisoning
can steal you child's future,'' ran in the Major League
Baseball Official program in 2002 during the five game American
League Championship series.
EPA funds two types of lead grants to Native American Tribes
annually. One grant is for testing and analyzing lead in blood,
paint, dust and soil and for conducting inspections and risk
assessments of pre-1978 tribal homes for hazardous lead levels.
The second grant is for developing and implementing lead
awareness educational outreach activities for tribes.
We have also sought to reach the Spanish-speaking population in the
United States through the development of Spanish publications
and targeted outreach. Many of the EPA lead documents were
translated into Spanish. During Earth Day celebrations in April
2003, La Opinion, a newspaper serving over 1 million Hispanic
readers in New York, Miami, Houston, Chicago, and Los Angeles,
featured a two-page spread on EPA's Lead Awareness Program.
We are currently developing a voluntary partnership to further the
use of lead safe work practices during renovation and
remodeling of pre-1978 housing. This Lead Safety Partnership
will be a collaboration between EPA, home remodelers,
contractors, and trade associations. The members will pledge to
use lead safe work practices and in exchange receive support
through promotional materials and network opportunities that
the Lead Safety Partnership will provide. This market
differentiation will help the members gain more business while
protecting the health and safety of their clients.
EPA has worked with several different grantees over the last several
years: the National Council of La Raza, Hope Worldwide, and the
National Coalition for Lead Safe Kids, to develop public
service announcements, conduct education workshops, and
distribution of lead prevention materials to the general
public.

Response for the Record by Donald L. Correll, President and CEO,
Pennichuck Corporation, National Association of Water Companies
RESPONSES TO QUESTIONS FOR ENERGY AND COMMERCE COMMITTEE
Question 1: Your testimony mentions that the Federal government has
a role in taking on the lead problem, but also suggests that funding
for drinking water line replacement is not one of them. Could you
please clearly tell us where you believe the Federal role begins and
ends and where communities become responsible? Also, could you please
tell us where you think Congress could encourage strong management
practices by the water utilities?
Answer: Americans want their water utilities to provide safe,
reliable, and aesthetically pleasing water, as well as good customer
service, at no more cost than is necessary. These expectations are best
met over the long term by water utilities that are economically self-
sustaining. Like other utility services, water service should be paid
for by those receiving the service. It should not be chronically
subsidized by government. Should the water industry become too reliant
on government subsidies it will be all too subject to short-term
political and budgetary influences, which will inevitably weaken it. In
addition, as our experience with massive government subsidies to
wastewater utilities in the 60s and 70s (Construction Grants Program)
has shown, government subsidies do not foster either operating
efficiencies at utilities or sound capital investment programs over the
long-term. While government (at all levels, including Federal) does
have an important role to play in provision of water, that role should
be clearly defined so it encourages good management practices and
facilitates the industry ultimately becoming self-sustaining. The
alternative to this is an unending significant drain on the federal
treasury.
For example, clearly an important and appropriate role of the
federal government is in the standard setting and security arenas.
Under the Safe Drinking Water Act, Congress designed a standard setting
and enforcement process implemented by EPA and the states that assures
the safety of our drinking water. This is clearly an appropriate
federal role, since health standards should not differ from one region
to the next. Similarly, given the national implications of terrorism,
the federal government has a role in working with utilities to assure
the drinking water supply is safe from terrorist attack. This is done
by providing economic assistance where needed in assessing
vulnerabilities, sharing information, developing strategies, conducting
research, etc.
Where the federal government needs to remain judicious in its
actions is in the financial assistance to utilities. Federal assistance
of this nature if not carefully structured can easily distort the
industry, create huge inefficiencies, and actually do more long-term
harm than good. As discussed above we saw this in the wastewater
industry under the old Construction Grants Program, which failed to
produce either improved operating efficiencies or sound capital
investment practices.
This is not to say that there isn't a need for some federal
financial assistance in the water arena. There are small and
disadvantaged communities with poor economies of scale where improved
management efficiencies, better asset management, consolidation, and
public-private partnerships won't be enough to address the communities'
financial challenges while keeping the water affordable. There may also
be customers in larger communities that may find water rates
unaffordable in the future. In these cases it is appropriate for the
government to step in and provide economic help. However, again, the
manner of that assistance should be carefully structured to insure the
subsidies are not going to communities or those customers who can
afford to pay the full cost of water service.
NAWC supports the Drinking Water State Revolving Loan Fund (DW-SRF)
and have found it to be a well-structured and useful program. While
this program offers a modest subsidy in the form of low interest loans,
we believe this kind of program, where the principle must be paid back
(and can be reused over and over), provides the kind of incentives that
encourage utilities to take charge of their own future through
efficient management and sound long term investments. While there are
areas where it could be improved (which we have addressed in more
detail at this and other hearings of your Subcommittee), the DW-SRF
should remain the primary conduit for federal financial assistance.
Keeping with our goal of the self-sustainability of the industry,
NAWC supports updating the SRFs to encourage utility practices which
support this self-sustainability. We support using the SRF assistance
to facilitate improved management of the utility. In recent years there
have been various pieces of legislation drafted and considered which
would creatively use SRF assistance as a carrot to encourage utilities
toward self-sustainability. If SRF assistance were tied to improved
utility asset management, progress towards full cost-of-service rates,
and consideration of consolidation and public-private partnerships, the
federal government will have gone a long way to encouraging and
assuring the self-sustainability of the industry and closing the
infrastructure financing without needlessly relying on tax payer funds.
Question 2: Your testimony suggests that privately owned drinking
water utilities should be able to receive Federal funding from the
Drinking Water Revolving Loan Fund. This would be a new grant of
authority. With the funding gap that many people are arguing exists in
drinking water funding, why should private companies have access to
these funds?
Answer: First, allow me to clarify. Under the Safe Drinking Water
Act, private companies are currently eligible for Drinking Water State
Revolving Fund (DW-SRF) assistance. The problem that I discussed in the
testimony exits at the state level, where 10 states (Alabama Arkansas,
Colorado, Georgia, Kansas, Mississippi, North Carolina, Oklahoma,
Tennessee, Wyoming) currently do not allow private companies to receive
SRF funds no matter what the utility's needs might be and in clear
violation of Congressional intent.
There are those who oppose private utility access to the DW-SRF,
and presumably want to see private utilities excluded from it on the
State and Federal level. We would strongly oppose this (and
incidentally strongly support opening up the Clean Water SRF to private
utilities).
When the DW-SRF was authorized in 1996 Congress correctly
determined that the benefits of the SRF would flow to the customers of
a utility, not the utility itself or its stockholders. This is assured
by the various State Public Utility Commissions, which set and oversee
our rates and are on record supporting private utility access.
Furthermore, customers of private utilities pay the Federal and state
taxes that fund the SRFs, just like the customers of municipal
utilities do. With these facts in mind, there is no good reason that
private utilities (or more accurately, the customers of private
utilities) should be denied the benefits of the SRFs at either the
state or Federal level. Such exclusion effectively makes some tax-
paying Americans second-class citizens, which of course is not right.
Question 3: Your testimony suggests the Center for Disease Control
should do a comprehensive study of lead and formulate a national
strategy to reduce lead from all significant sources. What role, if
any, do you think EPA should play in this matter since EPA is the
regulator of lead in soil, water and air?
Answer: NAWC testified that the Center for Disease Control should
do a comprehensive study of the lead contamination problem and
formulate a national strategy for addressing this important issue.
Lead, unlike most contaminants EPA regulates, comes primarily from
within customers' homes and service lines. It is a byproduct of
corrosion, is sensitive to water chemistry, and therefore can be highly
variable and unpredictable. Some corrective actions such as removal of
lead service lines are expensive and can at least for a time make the
problem worse. Because of the less than perfect solutions and costs of
remediation, having an independent review of the health impacts of lead
exposure may help EPA and others determine the best courses of action
to minimize health impacts, taking costs and effectiveness of the
available remediation actions into account. Our belief that this study
should be carried out by CDC is based on that organization's extensive
experience in matters relating to health. The CDC is uniquely qualified
to carry out such a study and then make recommendations to Congress and
EPA. NAWC still believes, however, that the regulatory burden of
establishing and maintaining the regulations that govern what is
considered an acceptable level of lead in water as well as any
enforcement of those regulations should remain with EPA.
Question 4: You indicate that a water investment gap will occur
only if estimates are accurate and no action is taken to ``close'' the
gap. I don't believe we will determine today precisely how accurate all
the estimates are--so let's talk about the second factor.
A) You mention that there is under pricing for water services. On
what data do you rely in making this argument? Could you provide such
data to the Subcommittee?
Answer: (A) The concern about under-pricing is widely shared in the
industry. The source of our data is a 2002 General Accounting Office
report, titled Water Infrastructure, Informational on Financing,
Capital Planning, and Privatization.
Under-pricing is unlikely for the privately-owned segment of the
industry because we are regulated economically on the State level by
the various State Public Utility Commissions which oversee and set our
rates. The Commissions understand the long-term need to recover costs
in order to remain financially viable.
The concern about under-pricing is greater for publicly owned
utilities that may not practice full-cost pricing methods. Publicly
owned systems also have more opportunities to subsidize water
operations directly or indirectly through other municipal operations
and/or through tax revenues and other cross-subsidizations which may or
may not be apparent to the ratepayer. Publicly owned systems which are
typically not regulated by State Public Utility Commissions also may
face political pressure to defer expenditures and/or simply keep water
(and wastewater) prices down, with little or no regard to the true cost
of providing the service.
(B) You cite under pricing, yet I believe past NAWC testimony
indicated that water rates are rising faster than the overall rate of
inflation. Will these two lines ``cross'' at some point in the future,
meaning will rates catch up with expenses? Or are we in a situation
where ``real'' expenses for capital improvements and the like are
rising much faster than inflation for the foreseeable future due to
deferred maintenance and other factors? How can cost-efficiencies
affect this situation?
Answer: The trend line suggesting that prices are rising faster
than the overall rate of inflation simply suggests that, in relative
terms, this is a rising-cost industry. There are other examples in the
economy: college tuition and health-care costs. It is important to note
that the water sector is the most capital intensive of all the utility
industries. Some services, like long-distance phone service, are
experiencing below-inflation price trends. As long as we are trying to
step-up the pace of investment and meet other new demands as they come
along (e.g., water treatment and security costs), exceeding the rate of
inflation seems likely. Keep in mind that these trends are relative to
overall trends in inflation, which might also change with the economy.
Economics of scale, operational productivity and efficiency
improvements have the potential to be very beneficial in controlling
costs. Also, regulatory models can provide positive performance
incentives for cost control.
