I. INTRODUCTION

South Carolina Department of Health and Environmental Control (SCDHEC),

United States Geological Survey (USGS), South Carolina Wildlife and Marine

Resources Department (SCWMRD), Corps of Engineers and United States Fish and

Wildlife Service (USFWS) have routine ambient monitoring programs in the

coastal counties. These agencies do not necessarily have stations on the

same waterbodies, except for the Cooper River, where all the agencies monitor

water quality. The prediversion, partial rediversion, and the full-scale

rediversion of the Cooper River to the Santee River, and the subsequent effects

on water quality and biological communities are being studied by these

agencies.

The locations of all monitoring stations in each coastal county are pro-

vided on South Carolina Highway County maps of �-inch equals a mile scale (maps

located in appendices G thru N). The maps reflect the following sampling

station configuration:

1. The SCDHEC sampling network is spread throughout all the coastal

counties with concentrations in the areas where dischargers or

shellfish grounds are located.

2. The USGS sampling network is concentrated in Berkeley, Georgetown,

and Horry Counties with one or two stations located in Beaufort,

Colleton, Charleston, Dorchester, and Jasper Counties.

3. The Corps of Engineers, SCWMRD, and USFWS each have five monitoring

stations located on the Cooper River which were established for a

special study.

II. SOUTH CAROLINA DEPARTMENT OF HEALTH AND
ENVIRONMENTAL CONTROL MONITORING PROGRAM

SCDHEC has a routine water quality trend monitoring program consisting of

73 primary stations and 50 secondary stations throughout the 8 coastal

counties.

The primary water quality stations are sampled in a uniform manner (since

1974) to establish an extensive long-term data base. Data from these stations

aid in identifying trends as well as providing data for water quality model-

ling purposes. Water quality models are used in developing wasteload alloca-

tions for incorporation into point source discharge permits. Data are also

used to indicate conditions relative to achievement of water quality standards

and classified uses established in State regulations. Primary stations and

location descriptions are listed by counties in Appendix A.

Factors considered in selecting primary stations locations are as

follows:

1. Influent to a stream segment (sub-basin)
2. Effluent from a stream segment
3. Major streams at state lines
4. Confluence of major streams
5. Above a major industrial area

-2-

6. Below a major industrial area
7. Water quality limited area
8. Major lake
9. Above major municipal area
10. Below major municipal area
11. Mouth of major tributary
12. Major water use area
13. Above major land use area
14. Below major land use area
15. Above a water intake
16. Sites also located as part of Intensive Water Quality Surveys
17. Other
The Environmental Protection Agency's Basic Water Monitoring Program has

included 26 of DHEC's 119 primary water quality stations into their monitoring

network. There are only 7 of these 26 stations located in the coastal

counties. The criteria for selecting the locations for the 26 stations are

the same as listed for DHEC's primary stations. Also, these stations are

strategically located in major waterbodies to provide a representative

picture of water quality throughout the State.

The EPA basic water monitoring program stations are identified by a double

asterisk within the listing of primary and secondary stations Appendix A.

Primary stations are sampled monthly, quarterly, and annually for various

parameters as described below. The data are computerized within a computer

system called STORET and are assigned computer storage and retrieval codes as

indicated.

Secondary stations are routinely sampled six (6) times per year, once

per month from May through October at locations described in Appendix A.

Factors considered in selecting Secondary station locations are as follows:

1. Known water quality problem areas; secondary stations act as a

supplement to primary stations where data historically shows poor

quality. These stations are usually located in relation to smaller

discharges throughout the State.

2. Potential water quality problem areas; stations in these areas are

located in high complaint areas, agricultural and domestic non-point

source areas, and areas where data have revealed poor conditions.

3. Areas with the same selection criteria as applied to primary

stations. In these cases the same problems or potential for

problems exist, but with a lesser degree of importance. These

areas still require monitoring, but on a less frequent basis.

The parameters sampled at each secondary station are listed below with

their corresponding STORET parameter codes:

All sampling procedures and analyses for the primary and secondary

stations samples are performed in accordance with the Standard Operating

Procedures Manual and Quality Assurance Procedure Plan (SCOHEC).

Depending upon the location of the stations within the coastal counties,

the samples are sent to DHEC Analytical Laboratories either in the EQC Trident

District Office in Charleston or the EQC Pee Dee District Office in Florence

for analyses. These district laboratories initiate the analyses; however, the

EQC laboratory in Columbia provides analyses for metals, nutrients, toxic

extraction procedures, and organics. The district and central laboratories

analyze samples, record the results, verify the results, and send the data to

the Water Quality Monitoring Section in the Bureau of Water Pollution Control.

The Water Quality Monitoring Section reviews and edits the data prior

to submittal to automated data processing for storage in STORET. The data

base can be accessed by any STORET user. The system was designed and imple-

mented by the United States Environmental Protection Agency.

III. SCDHEC SHELLFISH MONITORING PROGRAM

The Shellfish Monitoring Program seeks to provide data which accurately

reflect the worst physical, chemical, and biological conditions of pollution

of coastal shellfish growing waters in South Carolina. This is a conservative

approach to help insure that the health of shellfish consumers is protected.

The State's coastal area is divided into 20 shellfish management areas with a

total of 350 monitoring stations. Stations within each area are identified as

critical and non-critical.

This sampling network serves two important roles in the shellfish program.
It provides a water quality data base which is included in a sanitary survey
of each shellfish area. These surveys are conducted every three years with
yearly updates and are used to classify shellfish waters for harvesting suit-
ability. The sampling network also serves to provide continuous monitoring
of each shellfish area to insure that conditions which existed during the
sanitary survey still prevail and that the harvest classification is correct.
All shellfish waters receive one of the following harvesting classifications:
Approved: Areas where a sanitary survey indicates that the water is not
contaminated with fecal material, radionuclides, industrial
wastes, or marine toxins such that the consumption of shellfish
might be hazardous. The total coliform MPN (most probable
number) median does not exceed 70/100 ml in the water and 10%
of the samples do not exceed 230/100 ml.
Conditional: Areas of the same general quality as in the approved areas;
however, the quality varies because of impacts from non-point

I ~~~~~~and point sources, runoff, and seasonal activities. Shell-
fish are not allowed to be marketed when the approved area
standards are not met.
Restricted: Areas impacted by known non-point and/or point sources. There
may be a limited degree of fecal pollution that makes the
shellfish unsafe for direct market harvesting. The shellfish,
however, may be marketed after relaying or depuration. The
median total coliform levels in water are between 70 and
700/100 ml with not more than 10% of the samples exceeding
2300/100 ml.

-7-

Prohibited: Areas where a sanitary survey indicates pollution from radio-

nuclides or industrial wastes or the median total coliform

MPN exceeds 700/100 ml in the water or more than 10% of the

samples exceed 2300/100 ml. Prohibited areas include desig-

nated buffer zones around marinas and wastewater treatment

pl ants. These buffer zones are established as 'safety factors

in case of accidental pollution.

All sampling and analyses are conducted in accordance with approved Food

and Drug Administration procedures and those referenced in Interstate Shellfish

Sanitation Program guidelines relating to shellfish sanitation.

Shellfish program water quality stations have been designated critical or

non-critical depending upon the location of the station.

1. Critical Stations

Critical stations are established at locations which have potential

for variable water quality and are important for public health protection.

These sites are often located at a harvesting classification boundary to

more accurately delineate the classification changes. All stations in

conditional harvesting areas are critical stations. There are 219

critical stations where water samples are collected six times per year

during shellfish harvesting season (August 15 - May 15).

Shellfish meat samples are collected once per year at all critical

stations. Shellfish are filter feeders and can concentrate contaminants

and these samples provide a measure of the bacteria] quality of the

shellfish meats.

2. Non-Critical Stations

Non-critical stations are located within large areas with the same

classification throughout. These stations are strategically located
to reveal changes in water quality within shellfish growing areas. There

are 119 non-critical stations where water samples are collected four

times per year during shellfish harvesting season. Results are used in

determining classifications.
Sampling is performed by personnel in the three coastal Environ-

mental Quality Control Districts. Analyses are performed by a DHEC

laboratory on Sullivans Island dedicated to the Shellfish sampling

program. The following table outlines the number of stations by EQC

District and shellfish management area.
Critical Non-Critical
District Areas Stations Stations
Waccamaw 01 through 05 39 28

Trident 06 through 13 106 30
Low Country 14 through 20 74 61
219 119I

There are 12 additional stations which are presently inactive but

since data are available, they are included as part of the shellfish

monitoring network description.

IV. SOUTH CAROLINA DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL INTENSIVE
WATER QUALITY SURVEY AND SPECIAL STUDIES PROGRAM

Even though there are primary and secondary trend monitoring stations

located throughout the coastal counties, there are cases where special studies

are required to get a more in depth picture of the water quality.

Intensive water quality surveys are conducted for gathering field data

for calibration or verification of water quality mathematical models and to

determine the quality of the State's waters and biological communities. The

Department's goal is to calibrate models with measured field data when deter-

mining point source wasteload allocations resulting in advanced treatment

requirements. Emphasis and priority is also placed on gathering field data

for issuance of wasteload allocations for waste treatment projects funded with

EPA grants under Section 201 of the Federal Clean Water Act. Special studies

are designed and carried out as described in the Basic Water Monitoring

Program (SCDHEC publication).

Intensive water quality surveys are generally performed during May through

October. Winter months are less desirable for intensive water quality surveys

used for model calibration since higher temperatures are best for determining

worst case conditions. This is based on the following factors:
1. Biochemical reaction rates and biological populations are lowered by
colder temperatures.
2. Generally, the flow in the streams is higher and much less pre-
dictable in the winter.
3. Dissolved oxygen concentrations are higher due to higher saturation
levels and oxygen demand lower due to lower temperatures in the
winter.
4. For modelling purposes, it is desirable to conduct field studies
which result in data closely aligned to the worst-case conditions
under which water quality predictions are made. For example, pre-
dictions are normally based on low stream flows (1Q10).
5. On those occasions where seasonal wasteload allocations are at issue,
studies may be conducted during the winter months.
An additional objective of special studies is to provide immediate and
in depth investigations of specific environmental problems and to conduct
practical research programs which will lead to a better understanding of the
water quality of the State of South Carolina. Each study is documented in a
report which discusses the data obtained during the study and conclusions.
These reports are available to the public and interested agencies and are
listed in chronological order in Appendix C.

V. UNITED STATES GEOLOGICAL SURVEY MONITORING PROGRAM
The United States Geological Survey (USGS) has 37 routine monitoring
stations in the coastal counties. The criteria for selecting the locations
for the stations are as follows: 1) to provide data on the before and after
affects of rediversions on the water quality and aquatic community of the

Cooper River; 2) to gather data at various river flows to better characterize

the assimilative capacity of the Waccamaw River and the Intracoastal Waterway,

and 3) to provide additional routine monitoring data where information was not

available. These stations and location descriptions are listed by counties in

Appendix D.

All USGS monitoring stations are sampled every hour using a probe recorder

which transmits the results to a spool tape. The stations located on the

Cooper River use the spool tapes as well as the Data Collection Platform

Satellite, which transmits the data to the USGS office computer in Columbia

every 3 hours.

The parameters sampled are listed below with their corresponding STORET

parameter codes:

Specific Conductivity 00095
Temperature 00010
pH 00400
Dissolved oxygen 00300

The probe used at each station has the capacity to simultaneously record up to

10 parameters and is calibrated weekly. The data tapes are collected monthly

and edited against previous values. Once there is assurance the values

recorded fall within an acceptable range, the data is then entered into STORET.

USGS has three ongoing special studies in the coastal counties and are

listed below:

1. Determination of flood hydrographs for South Carolina streams.

This project includes 4 stations in the coastal counties that monitor

rainfall and runoff at intervals ranging from 5 to 15 minutes. Data will

be available -in a published report and in the USGS computer database,

WATSTORE.

-12-

2. Impact of water withdrawal from the Intracoastal Waterway and Bull Creek

in Grand Strand area, South Carolina.

The objective of this project is to predict the movement of the fresh-

water-saltwater interfaces in the Intracoastal Waterway under conditions

of proposed withdrawal of fresh water from the Waterway near Enterprise

Landing and from Bull Creek 7 miles upstream from the waterway. As part

of the study, several monitoring stations have been installed.

3. Saltwater encroachment in the upper Floridan aquifer in the Hilton Head

Island area, South Carolina.

While this project is oriented toward groundwater, it is included in this

list because of the importance of this issue to the coastal zone. The

objective is to determine the rate of encroachment of saltwater into the

freshwater aquifer under Hilton Head. As part of the study, groundwater

quality is being monitored at several sites in the area.

Also, USGS has completed seven special studies in the coastal counties

and are available to the public and interested agencies upon request. These

studies are listed in chronological order in Appendix E.

VI. CORPS OF ENGINEERS MONITORING PROGRAM

The Corps of Engineers, Charleston District, has installed five "real

time" salinity intrusion sampling stations in the Cooper River near Bushy Park.

These stations and location descriptions are listed in Appendix F.

USGS (Columbia office) has been contracted by the Corps of Engineers to

collect the samples by telemetry via Data Collection Platformi Satellite. The

data is collected every hour and transmitted to the USGS Columbia Office

every three hours.

-13-

The parameters sampled are listed below with their corresponding STORET

parameter codes:

Specific Conductivity 00095
Temperature 00010
pH 00400
Dissolved Oxygen 00300

Once the data has been received by the USGS Columbia Office, the data

are reviewed against previous values, edited and entered into STORET. STORET

is the same water quality data base used by SCDHEC.

During 1985, the Corps of Engineers has been doing prototype testing of

the rediversion. This is an ongoing special study and information can be

obtained upon request.

Vii. SOUTH CAROLINA WILDLIFE AND MARINE RESOURCES MONITORING PROGRAM

South Carolina Wildlife and Marine Resources Department (SCWMRD) has

established five routine biological monitoring stations on the Cooper River.

These stations are sampled to collect baseline data prior to the full-scale

rediversion and the sites were selected to maximize comparison with the data

obtained from the prediversion studies and the other monitoring programs

being conducted by SCDHEC, USGS and the Corps of Engineers. These stations

and location descriptions are listed in Appendix F.

The parameters that are sampled are listed below:

Temperature bimonthly surface & bottom
Salinity bimonthly surface & bottom
pH bimonthly surface & bottom
Nutrients bimonthly surface & bottom
Turbidity bimonthly surface & bottom

These parameters are analyzed by the Survey II Digital Hydro Lab and

values are recorded at the sampling site. The results are not accessible

through a interagency computer and can only be obtained upon request.

The SCWMRD has completed a special study and have two ongoing special

studies in the coastal counties. These studies are as follows:

-14-

1. Coastal Contaminant Survey - Stations are sampled semi-annually for water

quality parameters, sediments, and where possible, oysters are collected

and analyzed for tracemetals and organics (September 1985; May-June 1986).

These stations are located throughout the eight coastal counties,

beginning at the Waccamaw River in Horry County and ending with Calibogue

Sound in Jasper County.

2. A Study to Monitor Concentrations of the Pesticide Nibrom in Estuarine

Habitats around Parris Island, S.C. This study would indicate what

effects the spraying of pesticides would have on decapods and water

quality in the Parris Island area (October 1985).

3. Cooper River Rediversion Study. The objectives of this study is to

collect a baseline data prior to complete rediversion and the effects on

the 5 parameters sampled (ongoing project since 1984).

VIII. UNITED STATES FISH AND WILDLIFE SERVICE MONITORING PROGRAM

United States Fish and Wildlife Service (USFWS) is concerned about the

potential increase in contaminants in the Cooper River and the affects on fish

and birds which feed on aquatic organisms. In 1985, five biological moni-

toring stations were established on the Cooper River to study contaminants,

the effects on the aquatic organisms, and to establish baseline data prior to

fullscale rediversion of the Cooper River to the Santee River. These stations

and location descriptions are listed in Appendix F.

The USFWS Charleston office uses the Patuxent National Wildlife Research

Laboratory in Patuxent, Maryland to analyze whole fish tissue samples from

catfish and garfish for heavy metals, PCBs, and pesticides. These parameters

would indicate if the discharges from the industrial park facilities on the

Cooper River were causing any biological problems downstream. The results of

the sampling program can be obtained upon request from the USFWS.
