Defense General Supply Center (DGSC), south of Richmond, Virginiain Chesterfield County, is a military supply distribution center. The facility currently manages and furnishes military generalsupplies to the Armed Forces and several federal civilianagencies. Past chemical handling, storage, and disposalpractices have contaminated groundwater, soils, surface waters,and sediments in the area (DGSC 1993a). Contaminants, primarilyvolatile organic chemicals, in groundwater and surface water havemigrated to adjoining communities.

A well survey was conducted in March 1987 by the ChesterfieldCounty Health District, part of the Virginia Health Department. Some private wells were sampled at the time of the survey in theRayon Park area, adjacent to the National Guard Area on DGSC, andthe water contained contaminants at levels above regulatorylimits. Because of those levels, 21 private wells in thecommunity of Rayon Park were replaced with an alternate watersupply in 1987. Because of infrequent exposure to low levels ofVOCs in those wells, adverse health effects are not likely. Theactual duration of those past exposures is unknown.

In June of 1992 private well sampling was conducted in theKingsland Creek and Rayon Park area and showed no currentcontamination, with one exception. Lead was detected aboveappropriate drinking water standards in one well. The source oflead contamination has been attributed to well piping sincesampling results from five other wells did not detect lead. Thathomeowner was referred to a health professional at the VirginiaDepartment of Health (DGSC 1993ba, DGSC 1993b).

To document the number of wells near DGSC, a well survey wasperformed in October 1992 at residences within a quarter mile,off-site of DGSC. Of the 108 responses, 16 residences usegroundwater as their potable water source (DGSC 1993a, DGSC1993b, DGSC 1992c). If future studies determine that groundwaterplumes may be suspectedto be heading in the direction of privatewells, those wells should be periodically sampled.

Citizens have expressed concerns about contamination toinstallation officials and representatives of state and localhealth departments. They are also concerned about possibleadverse health effects associated with past use of contaminatedgroundwater and on-going monitoring efforts being conducted byDGSC. Those concerns are evaluated in the Public Health Implications section of this public health assessment.

Available health outcome data indicate there are elevated cancermortality rates for men in Chesterfield County compared withstate rates. Those elevated rates were recorded for cancersassociated with the oral cavity and respiratory tract for theyears 1950 through 1979. Elevated cancer mortality rates werenot found in women in Chesterfield County. ATSDR cannotdetermine if the elevated cancer mortality rates in men arerelated to exposure to DGSC contaminants because site-specifichealth outcome data are not available for communities near DGSC. Data are also not available on smoking and occupational statusfor communities near DGSC, and those factors are known tocontribute to the development of the types of cancers observed inChesterfield County men. The medical and scientific literaturehave not linked exposure to contaminants (VOCs) that weredetected in the water of off-site private wells with developmentof cancers associated with the oral cavity and respiratory tract. However, the cancers that were elevated in men are associatedwith smoking cigarettes and chewing tobacco and snuff (SurgeonGeneral Report 1982, Hoffmann et al 1983, Amdur et al 1991).

Additional field work is ongoing for areas on and off theinstallation. That data will provide information on groundwater,soils, sediment, and surface water (DGSC 1992c, DGSC 1993a). Samples have been analyzed and the results are currently beingevaluated by the installation. That information will beavailable to the public in the next few months. Also, an interimproposed plan for groundwater remediation east of the NationalGuard Area is being prepared. The purpose of the proposed planis to prevent further migration of DGSC contaminants and will beavailable to the public. ATSDR has reviewed and incorporatedthat data into this assessment.

DGSC is classified in the category of no apparent public healthhazard. Although thereare no known current exposure pathwaysfor DGSC, recommendations have been made in this public healthassessment to prevent or eliminate the possibility of futurecompleted exposure pathways.

ATSDR's Health Activities Recommendations Panel (HARP) determinedthat citizens living in communities near DGSC need informationabout their potential for exposure, the extent of contaminationat DGSC, sampling results for DGSC, and additional environmentalsampling and remediation that is planned at DGSC. DGSC continuesto address those issues through public meetings, environmentalfact sheets, and communication of private well sampling resultsto homeowners whose wells have been sampled. Currently, thereare no indications that adverse health conditions are occurringor have occurred from past exposures to DGSC contaminants. However, if in the future, groundwater contaminants are detectedat concentrationsof public health concern in off-site privatewells, community health education concerning exposure isindicated.


A. Site Description and History

Defense General Supply Center (DGSC), an operation of the DefenseLogistics Agency, is south of Richmond, Virginia in ChesterfieldCounty (Figure 1). The 640-acre, fenced installation was builtin 1941 and 1942. The original site consisted of the RichmondGeneral Depot and the Richmond Holding and Reconsignment Point. In May 1943, the installation was re-named the Richmond ArmedService Forces Depot and was used jointly by the Quartermaster,Engineer, Medical, and Ordnance Corps. Activities at theinstallation increased during World War II, when 5,500 civiliansand 457 military personnel worked at the site. A parcel of landoutside the western perimeter of the installation was leased froma private citizen and used as a German prisoner of war campduring World War II. In 1962, the installation became theDefense General Supply Center. The facility currently managesand furnishes military general supplies to the Armed Forces andseveral federal civilian agencies.

Past operations that contributed to contamination ofenvironmental mediaincluded industrial operations, such asrefrigerator repair, equipment overhauling, and enginerebuilding; flammable, toxic, and corrosive chemical storage andshipping; pesticides storage, mixing, and shipping; sanitary andindustrial waste disposal and treatment; and fire-trainingexercises. Groundwater contaminants, primarily volatile organicchemicals (VOCs), have migrated from the facility to privatewells in the adjacent community of Rayon Park. Contaminants havealso migrated from the site through surface water and sediments. The Agency for Toxic Substances and Disease Registry(ATSDR)prepared a healthconsultation on May 9, 1986, addressing privatewell contamination near DGSC. At that time, the VOCs in theprivate wells were not at concentrations believed to beassociated with adverse health effects.

In 1981, a team of investigators from Chemical SystemsLaboratory, Installation Restoration Branch, Aberdeen ProvingGround, Maryland, conducted an inspection of potential sites forremediation to be listed on the DGSC Installation RestorationProgram (IRP); 25 sites were evaluated (Figure 2). The teamrecommended that the central Open Storage Areas (sites 4, 5, and8), Area 50 (site 9), and the Fire-Training/Waste Disposal Pit(sites 16 and 17) be further assessed because of theenvironmental contamination at the sites. The team alsorecommended cleaning up the DDT spill in Building 202 (site 2)

Figure 2. Locations of Known or Suspected Waste Materials on DGSC

and improvement of storage and handling practices for pesticidesand polychlorinated biphenyl (PCB)-containing products.

In 1984, DGSC was proposed for inclusion on the NationalPriorities List (NPL). Originally, three areas were designatedfor study: the Fire Training Area, the Open Storage Area/Area50/National Guard Area, and the Acid Neutralization Pits (Figure3). In 1991, the areas were designated as eight operable units: three contaminated groundwater and five contaminant source areas. The source areas are the Open Storage Source Area (sites 4, 5,and 8; Figure 2), Area 50 Source Area (site 9; Figure 2),National Guard Source Area (labeled as National Guard Area,Figure 3), Fire Training Source Area (sites 16 and 17; Figure 2),and the Acid Neutralization Pits Source Area (site 7; Figure 2). The groundwater units include the Area 50/National GuardArea/Open Storage Area Groundwater, the Fire Training AreaGroundwater, and the Acid Neutralization Pits Groundwater. Thesource area remedial investigations are complete, and groundwaterstudies are now under way. In 1992, it was decided to proceedwith an interim remedial action for treatment of the groundwaterfrom the Open Storage Area/Area 50/National Guard Area. Thisarea has been designated as operative unit 9 (DGSC 1993a). Thatinterim proposed plan will be available for public review in lateApril 1993 (DGSC 1993b).

Focused feasibility studies currently are under way for thesource operable units. The Record of Decision (ROD) for the AcidNeutralization Pit Source Area is signed. The selected remedy isto treat soils in place using a vacuum extraction procedure. Theprocedure includes safeguards to protect the public health. TheROD for the Open Storage Area was signed on May 15, 1992 (LawEnvironmental, Inc. 1992a).

Additional field work for areas on and off the installation isbeing completed by the contractor, Law Environmental, Inc. Thiswork will complete RI/FS activities for the Acid NeutralizationPits, Area 50/Open Storage Area/National Guard Area, and the FireTraining Area. Expanded Site Investigations are planned at othersites (Buildings 68, 112, 202, and the Fuel Oil Storage Area) todetermine the need for RI/FS activities. That data will providerecent information on groundwater, soils, sediment, and surfacewater on and off the installation (Law Environmental, Inc. 1992b,DGSC 1992c, and DGSC 1993a). That report will be available tothe public in mid May of 1993 (DGSC 1993b). ATSDR has reviewedand incorporated pertinent data into this assessment.

On December 2, 1988, ATSDR released a preliminary public healthassessment of DGSC. The site was determined to be a potentialpublic health concern because environmental studies were notcomplete. Data now available are evaluated in this public healthassessment and reflect current public health concerns andenvironmental conditions at the installation. Groundwater

Figure 3. Source Areas Associated with Remedial Investigations and Expanded Site Inspections

studies are complete at Area 50 and are continuing for otherareas.

Brief background descriptions of all designated source areas(sites) are discussed in the following paragraphs. This information was gathered from the remedial investigations andfrom information obtained from DGSC, county, and state personnelduring the site visit (DGSC 1991a and DGSC 1992b).

Open Storage Area
This 43-acre, fenced area includes Open Storage Areas 38 through 47. The area is used to store drummed and containerized chemicals, primarily petroleum, oils and lubricants (POLs). This area has been in use since 1942. The drums are stored directly on the ground. The area has been the site of numerous spills and leaks since the time operations began. Three documented Malathion spills occurred in 1977. Presently, two plans, the Spill Prevention Control and Countermeasure Plan and the Installation Spill Contingency Plan, are in place to identify procedures intended to prevent, mitigate, and remediate spills (Dames and Moore 1989b). The ROD for the area was signed on May 15, 1992 (DGSC 1992b).
Area 50
From the late 1950s to the early 1970s, this site was used as a disposal area for chemicals and construction debris. Other wastes buried at the site may include toxic or reactive chemicals used in photographic development processes, organic solvents, pesticides, acids and bases, and POLs. The chemicals may have been placed in the landfill as bulk liquids or dumped in drums that have been damaged and are leaking (Dames and Moore 1989b).
National Guard Area
The Virginia National Guard leases this 15-acre area from DGSC. The site has remained relatively unchanged since the 1950s. The facility is composed of a number of maintenance shops and administrative buildings. The primary operations conducted at the facility involve vehicle maintenance. Past activities have included storage of fuels, oil, and solvents in above-ground and below-ground tanks. Also, waste solvents were washed into the storm sewer system or onto the pavement where they washed to bare ground. The floor drains inside the building are now tied to the sanitary sewer (Dames and Moore 1989b).
Fire Training Area
This area consists of at least three unlined pits, nowbackfilled with soil, that were used for fire trainingexercises. Pesticides, flammable liquid waste chemicals andpetroleum products were burned in these unlined pits (Dames and Moore 1989c).

Also located on the site is a former drum storage area usedfrom the 1950s to the early 1970s and a fuel storage tankthat is currently in use. Number 4 fuel oil leaked from thefuel storage tank to the adjacent area in 1978. A landfillused in the 1980s is located south of the site. Thelandfill is now closed (Dames and Moore 1989c).

Acid Neutralization Pit Area
These two concrete-lined pits received wastewater from acid and base metal cleaning and painting operations from 1958 to the early 1980s. Wastewater was discharged to the pits where solids were allowed to settle, then the water was adjusted for pH and discharged to the storm sewer until the late 1970s. Beginning in the late 1970s, the water was discharged to the sanitary sewer (Dames and Moore 1989a). Sludges were removed to the Chesterfield County Landfill every two to three years. When sludges were removed in 1985 to close the pits, the concrete liners were noted to be cracked and broken. The pits were backfilled with soil after the pits were washed clean of residue sludge. A Toxic Extraction Procedure conducted on the sludge indicated the sludge was not a hazardous waste (Law Environmental, Inc. 1992 ).
Aluminum Phosphide Residue Disposal Area
The site is a back-filled shallow excavation, about seven feet by 11 feet, in an open field near a wooded area. The site was used as a disposal area for aluminum phosphide residue (Environmental Restoration Company 1991). The site is still used for residue disposal on a limited basis (DGSC 1993a).
Parker Pond
This 80,000 square-foot pond and the area around the pond are used by base personnel and their families and guests as a recreational area. The pond is also used as a back-up water source for fire fighting. The pond is fished and stocked with bass, blue gill bream, and perch. The area around the pond is used for picnics. No swimming is allowed in the pond. The pond is under investigation because, in the summer of 1987, a fish kill occurred in Parker Pond. The fish kill was believed to be the result of low oxygen concentrations in the pond; however, a fish was analyzed for pesticides (see "On-Post Contamination" section for analysis results). A fountain has been installed to promote oxygenation of the pond (DGSC 1991a, DGSC 1991b, DGSC 1992b ). No waste disposal activities are known to have occurred in Parker Pond; therefore, the pond is not considered a contaminant source area.
Building 112--Pesticide Generalization and Recycling Building
This building has been used for the storing and mixing of insect, rodent and control agents since 1973. During early 1993, two monitoring wells were installed and used to identify the presence of groundwater contamination resulting from the activities surrounding this pesticide control center (Law Environmental, Inc. 1992b). Surficial soil samples were also taken (Law Environmental, Inc. 1993).
Building 68--Suspected PCB Spill Site
This building is also known as the Transitory Shelter and is on the north side of the installation. Transformers were previously stored on the lot of Building 68. On July 10, 1980, a PCB spill occurred during a transformer fluid transfer operation (Law Environmental, Inc. 1992b). No information is available on the amount that may have been spilled (DGSC 1991a and DGSC 1992b). Building 68 has been used as a storage area for fifty-five gallon drums of PCB-containing fluids, soils, protective clothing, as well as pesticides. During early 1993, surficial soil samples were collected from around Building 68 to quantify the level of pesticide and PCB contamination present (Law Environmental, Inc. 1992b, Law Environmental, Inc. 1993).
Transitory Shelter (Building 202)--Reported DDT Spill Site
Pesticides, including DDT, were reportedly stored in this building (DGSC 1991a, DGSC 1992b). Drums containing DDT were observed leaking during a survey conducted in March, 1980 by the United States Army Environmental Hygiene Agency (USAEHA). The leaking drums were located in the northern most fifty feet of the enclosed portion of the storage shed. During early 1993, surficial and subfloor soil samples were collected and analyzed to determine the level and extent of pesticide contamination present at this location (Law Environmental, Inc. 1992b, Law Environmental, Inc. 1993).
Fuel Oil Storage Area
A fuel oil storage tank south of Parker Road on EighthStreet, near the former Fire Training Area, experienced adocumented spill and release to the subsurface on November26, 1978. This spill was a result of a cracked valve andwas compounded by a rainstorm. When a valve wasinadvertently left open, the fuel oil exited the berm viathe drainage pipe. Fuel oil migrated overland andeventually reached Kingsland Creek. Significant quantitiesof oil were detected in the James River and obviouscontamination was recovered December 6, 1978 by a privatecontractor. An estimated 2800 liters of oil is believed tohave been released. Groundwater and subsurface soil sampleswere collected in the vicinity of this tank, during early1993 to identify the nature and extent of contamination thatmay exist (Law Environmental, Inc. 1992b, Law Environmental,Inc. 1993).

B. Site Visit

On March 26-27, 1991, ATSDR staff conducted a site visit at DGSC. ATSDR briefed the installation's Environmental Engineer, theDefense Logistics Agency representative, the Virginia Departmentof Waste Management representative, and local and staterepresentatives of the Virginia Department of Health on our goalsand the purpose of our visit. The Environmental Engineer for thefacility briefed ATSDR on the sites included in previousinvestigations and three additional areas that are now underinvestigation. He also directed a tour of those sites and areas. The observations are as follows:

The installation is completely fenced. Access to theinstallation is controlled by a guard at the gate. Administrative offices are located near the post entrance. Thehousing quarters for visiting officers are near theadministrative buildings. The majority of the post containswarehouses and processing buildings. Site-specific observations(DGSC 1991a) are discussed in the following paragraphs.

Open Storage Area
The fenced site is composed of three distinct, uncoveredareas. These areas, separated by roads, are used to storedrums. A railroad track separates the western storage areafrom the other storage areas. A major construction hasrecently been completed in the area.

The drums on the site are stored on bare ground with nocover. Drums are stored on their sides or in up-rightpositions. Although the temperature was in the 70s at thetime of the site visit, some of the drums were heardpopping. Most of the drums contain petroleum products;however, some drums were not clearly labeled such that theflash points of their contents are unknown. EPA iscurrently working with the installation to improve thissituation (DGSC 1992b).

Area 50
The northern portion of the site is a grassed area where monitoring wells and piezometers are located around the perimeter. A helipad is located on the northern-most sector, and a guard house is located on the northwest border of the site. A paved road provides access to the eastern border of this site. A paved parking lot is located on the southern portion of the site. A fenced transformer storage area is located to the west of the parking lot.
The National Guard Area
The fenced site is located across the east side of the access road from Area 50. The site is composed of administrative buildings, vehicle maintenance buildings, and paved vehicle and equipment storage areas. Runoff from paved, vehicle storage areas flows toward an No-Name Creek to the north and northeast of the site.
Fire Training Area
The site is bordered on the north by railroad tracks, on theeast by a railroad yard, on the south by the installationfence, and on the west by an installation road thatseparates the site from storage bays. Railroad trackstransect the east/west sectors of the site. All areas ofthe site are easily accessed by facility personnel.

The burn pits are in the northern sectors of the site. Empty drums are stored on the eastern sectors. A monitoringwell was observed in the southwest portion of the site. Standing water was noted adjacent to the south side of thewell. Empty pallets were noted on the western portion ofthe site just to the east of the fenced, Number 4 fuel oilstorage tank. Drainage is toward Kingsland Creek to thesouth.

Acid Neutralization Pits
The site is bordered by North 4th Street on the north, apaved driveway and buildings on the east, a grassy area onthe south, and Road C on the west. Access to the site isnot restricted to facility personnel.

Monitoring wells are located to the north of the large,northern-most pit and to the south of the smaller, southern-most pit. The pits have beenbackfilled with sandy clay andgravel. Drums of engine oil and cylinders of propane gasare stored on the northeast side of the site near North 4thStreet. Empty drums were stored east of the small, southernpit.

Aluminum Phosphide Residue Disposal Area
The area known as the Aluminum Phosphide Disposal Area is east of the Fire Training Area and north of Kingsland Creek. Access is unrestricted to facility personnel and visitors. The site is an isolated, cleared, grassy area with woods around three sides. A dirt road lies along the southern border of the site.
Parker Pond
The fishing pond and areas around the pond are recreational facilities for installation personnel. Picnic areas are located on the eastern side of the pond. Ducks were seen on the pond.
Building 112--Pesticide Generalization and Recycling Building
This building was not viewed during the initial site visit to DGSC, but is currently being investigated in an expanded site investigation.
Building 68--Suspected PCB Spill Site
The suspected site is next to a small storage building located on the northwest side of the installation. Although access to the area is not restricted to facility personnel, the location is not likely to receive heavy traffic.
Transitory Shelter (Building 202)--Reported DDT Spill Site
The site is composed of large, open warehouses where non-hazardous materials and empty drums are stored. A road runs between the warehouses.
Fuel Oil Storage Area
During the initial site visit, this area appeared to befenced off such that access by unauthorized personnel is notlikely. However, access to the area is not restricted tofacility personnel.

C. Demographics, Land Use, and Natural ResourcesUse

Information for this section was compiled from Census Bureaudata, the draft Community Relations Plan, the RemedialInvestigations, and information provided by the state and localhealth departments and the installation during the site visit.


DGSC is located in Chesterfield County, which is a rapidlygrowing suburban county south of Richmond. The installation isapproximately 10 miles south of Richmond (Virginia Department ofWaste Management 1991). Chesterfield County's 1990 populationwas 209,274 people, an increase of 46 percent from 1980. The1990 population was 84.6 percent white, 13 percent black, and 2.4percent other races. Approximately 16.6 percent of the 1990population were under age 10, and only six percent were age 65and older. This information is presented in Table 1 in AppendixA (U.S. Bureau of the Census 1991). Census information for 1990indicates that the installation had 42 residents when the censuswas conducted. The installation has 31 family housing units andsix visiting officers' quarters (DGSC 1992b). About 3,600 peopleare employed by the installation (U.S. Bureau of the Census1991).

Neighborhoods north of the installation include an elementaryschool, residential areas, and small businesses. Neighborhoodseast and southeast of the National Guard Area include a largegovernment-subsidized apartment project and Rayon Park, theresidential area with confirmed private well contamination(Figure 4). The 21 residences at which wells were tested are nowconnected to the municipal water supply. However, it is reportedthat some residents still use well water to irrigate theirgardens (DGSC 1991a, DGSC 1992b). At least three residences inRayon Park are still connected to private wells that were testedand showed no contamination in 1987 (DGSC 1992b). Those wellsare not regularly monitored (DGSC 1992a). Neighborhoods south ofthe installation are separated from the facility by KingslandCreek and steep inclines.

Census tract data for 1990 are presented in Table 1 in AppendixA. Block Group 1 consists of neighborhoods, including thesubsidized housing project, north of the installation and east ofthe National Guard Area. Block Group 2 includes neighborhoodseast of the installation and the Rayon Park subdivision northeastof the National Guard Area. Block Group 3 includes data for theinstallation and a neighborhood south of the facility (U.S.Bureau of the Census 1991).

Land Use

The communities around the installation consist primarily ofresidential areas and small businesses such as a small body shopand convenience stores. No major agricultural operations, otherthan a landscape/nursery operation, are within a one-mile radiusof DGSC. However, some residences in the area, including theRayon Park subdivision have small home gardens. DGSC is the onlymajor industry in the vicinity (DGSC 1991a, DGSC 1992b).

An elementary school is located within 100 feet northeast of theinstallation fence line (DGSC 1993a). The school is connected tothe municipal water supply. A government-subsidized housingproject is 0.25 miles east of the installation and is alsoconnected to a public water supply (DGSC 1991a).

A herd of seven to eight elk is maintained by the installation;hunting is not allowed. A stocked fishing pond (Parker Pond) onthe installation is used by facility personnel and their familiesfor fishing. The grounds around the fish pond are used forpicnic and play activities (DGSC 1991a).

Natural Resources

The majority of the residents in the Rayon Park Area usedgroundwater for potable and household purposes until the 1980s,when the wells were found to be contaminated and replaced withmunicipal water. No private well depths were provided ininformation reviewed, but both the upper and deeper aquifers arereportedly tapped for potable purposes in the area near DGSC(DGSC 1991a).

Private wells are still in use at some residences primarily southof the installation in the Kingsland Creek area, and a fewprivate wells are still in use northeast of DGSC in the RayonPark area. In October 1992, a well survey was performed byinstallation contractors to determine the number and location ofthe wells on the street closest to the southern border of the

Figure 4. Rayon Park Wells Associated With Past Contamination

installation. Of the 108 survey responses, 16 residences usetheir private wells for drinking water and other purposes withina quarter mile off site of DGSC (DGSC 1993b).

Four surface water systems are associated with DGSC: FallingCreek, about one mile north of the installation, an No-Name Creekat the northeastern boundary of the National Guard Area, andKingsland Creek, adjacent to the southern boundary of theinstallation (Figure 1). All of the creeks empty into the JamesRiver, which is about two miles east of the installation.

People in the surrounding communities have not been surveyed ontheir use of the surface water systems. Kingsland Creek is largeenough to support edible fish species, but local healthdepartment officials were not sure people fish at KingslandCreek. People do fish at the James River.

All of the creeks flow through or near neighborhoods wherechildren live and play. Although there was no documentation thatchildren play in the creeks, that is a reasonable possibility.

D. Health Outcome Data

The relevant health outcome data for the installation area areprovided below. The data are evaluated in the Public HealthImplications section. Data listed as items "2" and "3" cannot beevaluated at this time because those data bases contain less thanfive years of data. At least five consecutive years of data areneeded to determine if a significant disease is occurring.

  1. The EPA/National Cancer Institute (NCI) Riggans Mortality Tapes include information on cancer mortality rates for Virginia, Chesterfield County, and the United States.
  2. A state volunteer tumor registry has information on incidence of cancer at the zip code level. It is called the Virginia Tumor Registry.
  3. A state congenital anomalies reporting system, known asVA CARES, has information at the county level.


ATSDR discussed community concerns with the Virginia Departmentof Health, Chesterfield County Health District. Thoserepresentatives stated that the primary community health concernis for water quality of private well water used for drinking andother household purposes. ATSDR also attended a technical reviewcommittee meeting at DGSC on April 9, 1992, and no othercommunity concerns were identified from that discussion. Nocommunity health concerns were identified during the publiccomment period for this public health assessment. Other concernsthat were identified in the Community Relations Plan are these:

  1. The possible health effects from past use of contaminated private wells for drinking and other household purposes.
  2. The extent of contamination at the installation and currentmonitoring methods and remediation that are either ongoingor planned for the future.
