Integrated Report of the Urban Soil Lead Abatement Demonstration 
Project

AGENCY: Environmental Protection Agency.

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of a final report 
titled, Integrated Report of the Urban Soil Lead Abatement 
Demonstration Project (EPA/600/P-93/001 aF), as well as the pertinent 
underlying data sets and documentation. This Report is an integrated 
assessment of scientific data from the separate Boston, Baltimore and 
Cincinnati studies.

ADDRESSES: To obtain a single copy of the Integrated Report, interested 
parties should contact the ORD Publications Office, Technology Transfer 
Division, National Risk Management Research Laboratory, U.S. 
Environmental Protection Agency, 26 W. Martin Luther King Drive, 
Cincinnati, OH 45268; telephone: 513-569-7562; facsimile:

513-569-7566. Copies of the Integrated Report will be available on or 
about May 30, 1996. Please provide your name and mailing address, and 
request the document by the title and EPA number (EPA/600/P-93/001aF). 
Also, a limited number of the 1993 individual reports on the separate 
city studies are still available. The EPA document numbers for the 
separate three city reports are: Boston (EPA/600/AP-93/001b) Baltimore 
(EPA/600/AP-93/001c) and Cincinnati (EPA/600/AP-93/001d). There will be 
a limited number of paper copies of the Integrated Report available 
from the above source. Requests will be filed on a first-come-first-
served basis. After the supply is exhausted, copies of the Integrated 
Report and any of the individual final reports on the separate city 
studies can be purchased separately or as a set, from the National 
Technical Information Service (NTIS) by calling (703) 487-4650 or 
sending a facsimile to (703) 321-8547. The NTIS order numbers are: 
Urban Soil Lead Abatement Demonstration Project. Volume 1: Integrated 
Report (PB96-168356), Urban Soil Lead Abatement Demonstration Project. 
Volume 2: Boston Report (PB96-168364), Urban Soil Lead Abatement 
Demonstration Project. Volume 3: Baltimore Report (PB96-168372), and 
Urban Soil Lead Abatement Demonstration Project. Volume 4: Cincinnati 
Report (PB96-168380). The NTIS ordered number for the four volume set 
is PB96-168349.

used in the EPA Integrated Report and a copy of the accompanying 
documentation, can be obtained by contacting: Dr. Robert W. Elias,

SUPPLEMENTARY INFORMATION: The Urban Soil Lead Abatement Demonstration 
Project, generally known as the Three-City Lead Study, was authorized 
in 1986 under Section 111(b)(6) of the Superfund Amendments and 
Reauthorization Act [42 U.S.C. Sec. 9611(a)(6)] and was initiated in 
December 1986 in cooperation with states, state health departments, and 
local scientists. The purpose was to determine whether abatement of 
lead in soil could reduce the lead in blood of inner city children. The 
three selected cities, chosen in late 1987, were Boston, Baltimore, and 
Cincinnati. The individual results for each of the three cities were 
initially presented at an EPA-sponsored symposium in August 1992 and 
published as final reports in August 1993.
    While not part of the original project plan, EPA believed that all 
interested parties would benefit from an integrated assessment of data 
from the three coordinated studies. Thus, as an adjunct to the original 
project, this Integrated Report was developed. It includes further 
statistical analysis and integrates and standardizes, as appropriate, 
the results of the individual three cities studies into a single 
report.
    The final EPA Integrated Report on the Three-City Lead Study 
basically confirms the findings of the individual city reports. The 
Integrated Report concludes that:
    (1) When soil is a significant source of lead in the child's 
environment, the abatement of that soil will result in a reduction in 
exposure that will, under certain conditions, cause a reduction in 
childhood blood lead concentrations.
    (2) Although these conditions for a reduction in blood are not 
fully understood, it is likely that four factors are important: (1) The 
past history of exposure of the child to lead, as reflected in the 
preabatement blood lead; (2) the magnitude of the reduction in soil 
lead concentrations; (3) the magnitude of the other sources of lead 
exposure, relative to soil; and (4) a direct exposure pathway between 
soil and the child.
