The size of the site is generally indicated, based on information available at the time the site was scored using the Hazard Ranking System. The size may change as additional information is gathered on the sources and extent of contamination. Sites are arranged alphabetically by site name. CLEANING UP UNDER SUPERFUND The Superfund program is managed by the U.S. Environmental Protection Agency (EPA). It is authorized by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), enacted on December 11, 1980, as amended by the Superfund Amendments and Reauthorization Act (SARA), enacted on October 17, 1986. In October 1990, SARA was extended to September 30, 1994. An appropriation by Congress for Fiscal Year 1995 authorized Superfund to continue to operate. The Hazardous Substance Response Trust Fund set up by CERCLA as amended pays the costs not assumed by responsible parties for cleaning up hazardous waste sites or emergencies that threaten public health, welfare, or the environment; Superfund also pays for overseeing responsible parties conducting cleanup. Two types of responses may be taken when a hazardous substance is released (or threatens to be released) into the environment: • Removal actions — emergency-type responses to imminent threats. SARA limits these actions to 1 year and/or $2 million, with a waiver possible if the actions are consistent with remedial responses. Removal actions can be undertaken by the private parties responsible for the releases or by die Federal government using the Superfund. Remedial responses — actions intended to provide permanent solutions at uncontrolled hazardous waste sites. Remedial responses are generally longer-term and more expensive than removals. A Superfund-financed remedial response can be taken only if a site is on the NPL. EPA published the first NPL in September 1983. The list must be updated at least annually. EPA's goals for the Superfund program are to: Ensure that polluters pay to clean up the problems they created; and Work first on the worst problems at the worst sites, by making sites safe, making sites clean, and bringing new technology to bear on the problem. ------- REMEDIAL RESPONSES The money far conducting a remedial response at a hazardous waste siteXand a removal action, as well) can come from several sources: • The individuals or companies responsible for the problems can clean up voluntarily with EPA or State supervision, or they can be forced to clean • up by Federal or State legal action. • A State or local government can choose to assume the responsibility to clean up without Federal dollars. • Superfund can pay for the cleanup, then seek to recover the costs from the responsible party or parties. A remedial response, as defined by the National Contingency Plan (the Federal regulation by which Superfund is implemented), is an orderly process that generally involves the following steps: • Take any measures needed to stabilize conditions, which might involve, for example, fencing the site or removing above-ground drums or bulk tanks. • Undertake initial planning activities to scope out a strategy for collecting information and analyzing alternative cleanup approaches. • Conduct a remedial investigation to characterize the type and extent of contamination at the site and to assess the risks posed by that contamination. • Conduct a feasibility study to analyze various cleanup alternatives. The feasibility study is often conducted concurrently with the remedial investigation as one project. Typically, the two together take from 18 to 24 months to complete and cost approximately $1.3 million. • Select the cleanup alternative that: — Protects human health and the environment; - Complies with Federal and State requirements that are applicable or relevant and appropriate; - Uses permanent solutions and alternative treatment technologies or resource recovery technology to the maximum extent practicable; - Considers views of the State and public; and - Is "cost effective" - that is, affords results proportional to the costs of the remedy. • Design the remedy. Typically, the design phase takes 6 to 12 months to complete and costs approximately $1.5 million. • Implement the remedy, which might involve, for example, constructing facilities to treat ground water or removing contaminants to a safe disposal area away from the site. EPA expects the implementation (remedial action) phase to average out at about $25 million (plus any costs to operate and maintain the action) per site, and some remedial actions may take several years to complete. The State government can participate in a remedial response under Superfund in one of two ways: • The State can take the lead role under a cooperative agreement, which is much like a grant in that Federal dollars are transferred to the State. The State then develops a workplan, schedule, and budget, contracts for any services it needs, and is responsible for making sure that all the conditions in the cooperative agreement are met. In contrast to a grant, EPA continues to be substantially involved and monitors the State's progress throughout the project. • EPA can take the lead under a Superfund State Contract, with the State's role outlined. EPA, generally using contractor support, manages work early in the planning process. In the later design and implementation phases, contractors do the work under the supervision of the U.S. Army Corps of Engineers. Under both arrangements, the State must share in the cost of the implementation phase of cleanup. CERCLA requires that EPA select the remedy. ------- National Priorities List Rnal Rule #13 Site Summaries Table of Contents Page Site Name and Location 4..,..

AGRICULTURE STREET LANDFILL New Orleans, Louisiana Conditions at Proposal (August 23,1994): The Agriculture Street Landfill site is located in New Orleans, Orleans Parish, Louisiana, approximately 3 miles south of Lake Pontchartrain. The site is bounded on the north by Higgins Boulevard, on the east by Piety Street, on the south by Florida Avenue, and on the west by Almonaster Avenue. the Agriculture Street Landfill site was used as a municipal landfill as early as 1910. There is little information available regarding what was deposited in the landfill during this time period. Review of available file material suggests that the landfill received both solid and liquid wastes. This practice continued until 1950, when the advent of incinerators for ultimate disposal of these wastes was instituted. After the commissioning of the Florida Street Incineration Facility, combustible waste was incinerated and the ashes were disposed in the landfill. In approximately 1958, the operation at the landfill was interrupted; in 1965, the landfill reopened after Hurricane Betsy hit the City of New Orleans. Debris from destroyed buildings and furnishings were reportedly deposited at a rate of up to 300 truck loads per day. The debris was burned in the open dump; the area was covered with ashes from the city incinerators and compacted with bulldozers. Residential and commercial development of the area began in the mid-1970s and continued until 1987. Low income housing was constructed within the original boundaries of the landfill, including approximately 250 residences and the Gordon Plaza Apartments. The majority of the residents are minorities. A Site Inspection (SI) was conducted by EPA Region 6 on May 20 and 21, 1986. During the inspection, a total of 45 soil samples were collected on site. Results from the SI indicated that lead, zinc, mercury, cadmium, and arsenic were elevated in some samples. Concentrations in 12 of the 45 total samples exceeded 1,000 ppm lead, with three samples having lead concentrations greater than 4,000 ppm. The highest lead concentrations were found in an undeveloped area along the western and southern site boundaries; however, elevated lead levels were also found in other residential sample locations. Polynuclear Aromatic Hydrocarbons (PNAs) were detected in almost every soil sample. EPA Region 6 completed an Expanded Site Inspection in September 1993 at this site. EPA collected 133 surface soil samples and five subsurface soil samples from the site, residential yards, and school yards surrounding the site. Soil contamination is of concern due to observed contamination within residential yards. Chemical analyses of surface soil samples collected from 24 residential yards revealed the presence of arsenic and benzo(a)pyrene. Status (December 1994): A Remedial Investigation (RI) was completed in November 1994. The Feasibility Study is expected to be completed in early 1995 and will be released for public comments on possible remedies for the site. [The description of the site (release) is based on information available at the time the site was scored. The description may change as additional information is gathered on the sources and extent of contamination.

DC 20460 December1994 AQUA-TECH ENVIRONMENTAL INC. (GROCE LABORATORIES) Spartanburg, South Carolina Conditions at Proposal (August 23, 1994): Aqua-Tech Environmental Inc. (Groce Laboratories) is located on Highway 290 at Robinson Road in Greer, Spartanburg County, South Carolina. The site is a closed RCRA treatment, storage, and disposal facility (TSDF) which recently completed emergency response and removal activities under an EPA Unilateral Administrative Order (UAO). Upon closing Aqua-Tech, South Carolina Department of Health and Environmental Control (SCDHEC) and EPA emergency response personnel discovered approximately 7,000 drums and lab packs, 97 above-ground tanks, 1,200 gas cylinders (some containing phosgene and other toxic gases), unexploded ordnance material, and small amounts of low-level radioactive material and biohazard material at the site. Many of the drums, tanks, and cylinders were deteriorated, leaking, and improperly stored. Containers and debris were located throughout the 35-acre facility. Over 41,000,000 pounds of hazardous waste have been sent to the Aqua-Tech (Groce Labs) site, as documented by RCRA Hazardous Waste Manifests. From approximately 1940 until 196.8, the property was used as a municipal solid waste landfill. The City of Greer purchased the property in 1968, then sold it to Groce Laboratories in 1974. Groce Laboratories operated a hazardous waste treatment, storage, and reclamation facility over the former landfill site. Aqua-Tech Environmental, Inc. purchased the operations in April 1987 and continued to accept, store, and treat most hazardous wastes as well as a variety of other solid wastes. Most wastes were accepted in drum containers; however, bulk wastes, gas cylinders, and lab packs were also accepted. Both Groce Laboratories and Aqua-Tech Environmental, Inc. operated under RCRA Interim status. On September 4, 1991, after several complaints, RCRA inspection violations, and on-site accidents, Aqua-Tech Environmental, Inc. was ordered closed by SCDHEC due to the large volume of improperly stored hazardous waste and the imminent threat to public health. Several days later, Aqua-Tech's RCRA TSDF Part B application was officially denied. From September 1991 to January 1992, SCDHEC conducted emergency stabilization activities. In January 1992, EPA assumed emergency response and stabilization activities. EPA issued UAOs to more than 90 potentially responsible parties to continue emergency response activities. Site stabilization and removal/treatment of containerized wastes were conducted from September 1991 to January 1994. Four sources of hazardous materials were considered in the evaluation of this site. These include drums, above- ground tanks, contaminated soil, and manifested wastes. r Sampling investigations have been conducted by EPA, SCDHEC, and Aqua-Tech (Groce Labs). These investigations indicate significant contamination throughout the site including soils, drainage pathways, surface water, and ground water. Primary contaminants include metals, volatile organic compounds, and other contaminants. All of the surface water runoff from the property drains south into Maple Creek, a perennial water body which borders the site. Contaminants found in both this creek and the sources include cadmium, chromium, cobalt, lead, mercury, nickel, and zinc. Maple Creek flows eastward until it drains into the South Tyger River, which is used for fishing, and may also be used as a municipal drinking water source in the future. Status (December 1994): Negotiations are underway with PRPs to conduct an early enforcement lead Remedial Investigation and Feasibility Study (RI/FS). Negotiations are also underway to determine de minimis settlement with appropriate PRPs. [The description of the site (release) is based on information available at the time the site was scored.

DC 20460 December! 994 ATCHISON, TOPEKA AND SANTA FE TIE TREATMENT PLANT (AT&SF) Albuquerque, Bernalillo County, New Mexico Conditions at Proposal (October 14, 1992): The Atchison, Topeka and Santa Fe (AT&SF) tie treatment plant is an abandoned wood-preserving facility located at 3300 Second Street SW in the South Valley area of Albuquerque, Bernalillo County, New Mexico. The plant is in a commercial area of an Albuquerque suburb. The plant, owned by the AT&SF Railway Co., treated various wood products (railroad ties, bridge timbers, fence posts, etc.) with a solution of creosote and oil from 1908 until 1972. Washdown waters, spills, and leakage were disposed of hi an unlined impoundment. The facility, except for a waste water impoundment and a sump, was dismantled in 1972. The impoundment and sump cover approximately 3.4 acres. Sludge from the impoundment contains hazardous substances, including arsenic, barium, lead, and creosote constituents (3,4-benzofluoranthene, benzo(a)pyrene, and naphthalene), according to a 1990 report of the New Mexico Environmental Improvement Division (NMEID). No sludge is present hi the sump, but analyses of soil from the sump area detected hazardous substances, including barium, acenaphthylene, anthracene, fluoranthene, and benzo(a)pyrene, according to a 1990 report of an AT&SF contractor. The report indicates that fluorene, 2- methylnaphthalene, naphthalene, phenanthrene, pyrene, acenaphthene, anthracene, benzene, dibenzofuran, ethylbenzene, fluoranthene, and xylenes were detected in on-site monitoring wells. The Valley, or Basin Fill, Aquifer is the principal aquifer in the Albuquerque area. There are 15 City of Albuquerque and 3 Kirtland Air Force Base wells within 4 miles of the site. Run-off from the site enters an irrigation ditch south of the site. From this point, the drainage water travels through a series of canals until it enters the Rio Grande River 7 miles downstream from the site. No drinking water intakes are located along the canals and river. However, they are used as recreational areas and fisheries stocked by the State. Portions of the downstream segment along the Rio Grande are also considered wetlands according to Federal and State inventories. NMEID sampling conducted in January 1987 indicates that creosote constituents may have migrated from the site to surface water. Further documentation is required to establish that surface water is indeed contaminated. Status (December 1994): Since the site was proposed to the NPL hi 1992, AT&SF has entered into an Administrative Order on Consent (AOC) with the U.S. EPA Region 6 to conduct and finance a Remedial Investigation and Feasibility Study (RI/FS) for the site. The purpose of the RI/FS is to determine the nature and extent of contamination and any threat to the public health, welfare or the environment caused by the release or threatened release of hazardous substances, pollutants, or contaminants at or from the site, and to evaluate remedial alternatives to address the contamination. Sampling activities began in December 1993. [The description of the site (release) is based on information available at the time the site was scored. The description may change as additional information is gathered on the sources and extent of contamination.

DC 20460 Decembef1994 BAYTOWN TOWNSHIP GROUND WATER PLUME Baytown Township, Minnesota Conditions at Proposal (October 14, 1992): The Baytown Township Ground Water Plume site is defined by 34 contaminated wells (31 of which provide drinking water) in Baytown Township, Washington County, Minnesota. The county is one of the seven-county metropolitan area surrounding the Twin Cities. In June 1987, the Minnesota Department of Health (MDH) sampled wells in the area surrounding the Baytown Dump as part of a State-wide program to determine water quality near solid waste facilities. The results indicated private wells were contaminated with volatile organic compounds such as 1,1,2-trichloroethene (TCE), 1,1,2,2- tetrachloroethene (PCE), and cis-l,2-dichloroethene. MDH then issued a well advisory for the Baytown Township area. The MDH data indicate a plume of TCE-contaminated ground water extends for 3 miles from the main hangar complex at the Lake Elmo Airport. The majority of the plume continues through Baytown Township, involving a 1.5-mile-wide strip extending from Manning Avenue on the west to the St. Croix River. An estimated 10,450 live in the area, which is primarily agricultural and rural-residential. The highest concentrations of TCE were detected in the vicinity of the main hangar complex at the airport. TCE may have been used in parts cleaning activities in this area. Also, the contaminated wells at the airport have chlorinated solvent concentrations up to an order of magnitude higher than the majority of the contaminated wells located east of the airport, according to tests conducted during 1987-91 by State agencies and the Metropolitan Airports Commission (MAC), which owns and operates the Lake Elmo Airport. The location of the ground water plume suggests that at least a portion of the TCE may be attributable to a source on or near the airport property. Although some .of the TCE contamination may be attributable to past activities at the airport, other sources of TCE and other chlorinated solvents may also exist in the area. An estimated 26,000 people obtain drinking water from public and private wells within 4 miles of the site. Status (December 1994): The Minnesota Pollution Control Agency (MPCA) and MAC have continued ground water monitoring at the site. The Agency for Toxic Substances and Disease Registry (ATSDR) reportedly completed a health assessment of the site. MPCA has also been conducting a limited Remedial Investigation (RI) on their own.

DC 20460 December! 994 CHERRY POINT MARINE CORPS AIR STATION Havelock, North Carolina Conditions at Proposal (August 23,1994): Cherry Point Marine Corps Air Station is located within Havelock, Craven County, North Carolina. The air station covers 11,485 acres and is located on a peninsula between the Neuse River to the north and Core and Bogue Sounds to the south. The air station was commissioned in 1942 and a massive aircraft assembly and repair facility, which later became the Naval Aviation Depot (NADEP), was added in 1943. The NADEP Flight Line and Maintenance and Support Squadron are the primary generators of waste. Hazardous wastes generated by the air station include plating wastes which contain heavy metals and cyanides; organic solvents, paint removers and cleaners; waste petroleum, oil and lubricants; and polychlorinated biphenyl (PCB) wastes. Prior to 1982, most hazardous wastes were disposed on site. Presently, hazardous wastes are placed in drums and sent to the Defense Reutilization and Marketing Office hazardous waste storage facility for disposal off-site. Other hazardous and non-hazardous wastes are piped to the industrial wastewater treatment plant at the air station. Discharge of treated wastewater to Slocum Creek is permitted under the National Pollutant Discharge Elimination System. The air station submitted a RCRA Part A application on November 18, 1980, for the storage and treatment of hazardous wastes. The Part A application was modified and resubmitted on May 28, 1981. The air station submitted the first version of the Part B application on November 4, 1984 and submitted revisions in 1986, 1987, and 1988. Available file material does not indicate whether the Part B permit application has been approved. The hydrogeologic units which underlie the air station include a surficial aquifer, an upper confining unit, the Yorktown aquifer, a lower confining unit, and the Castle Hayne aquifer. A discontinuity occurs in the confining units in the southern part of the air station. The air station is supplied by 24 wells located on site which draw from the Castle Hayne aquifer. Sampling in 1986, conducted by the US Geological Survey, indicated elevated concentrations of benzene, arsenic, lead, and nickel in air station drinking water wells. Surface water runoff from source areas travels to Slocum Creek or its small tributaries, Turkey Gut and Schoolhouse Creek, which all drain into the Neuse River estuary. The Neuse River is a recreational and commercial fishery. Sediment samples collected from Slocum Creek, in 1987 and 1990, have documented PCB and arsenic contamination. Slocum Creek is a recreational fishery and a state-designated inland primary nursery area. Status (December 1994): Remedial action is underway to remove PCB contaminated soil at sites 1-5 and 1-17. A Base-wide sampling plan has been prepared to identify areas in need of remediation. This sampling effort will lead to a Remedial Investigation/Feasibility Study (RI/FS) and Record of Decision (ROD) for some areas.

DC 20460 December!994 CONCORD NAVAL WEAPONS STATION Concord, California Conditions at Proposal (February 7,1992): Concord Naval Weapons Station is located in the north-central portion of Contra Costa County, California. Approximately 30 miles northeast of San Francisco, it is bordered to the north by Suisun Bay and to the south and west by the City of Concord. The facility encompasses over 12,800 acres in three separate holdings: the Inland-Area (6,150 acres), the Tidal Area (6,650 acres), and a radiography facility hi Pittsburg, California. On-site activities also include administrative and support work. Transshipment operations are centered on the wetlands bordering Suisun Bay (Tidal Area). Wastes generated on site from base operations have been disposed of in the Tidal Area since base operations began in 1942. The Navy's substantial investigations of the station have identified 19 sites to be investigated under the Installation Restoration (IR) program, of which 8 are located in the Tidal Area. In addition, 24 Solid Waste Management Units (SWMUs) will be investigated, pursuant to RCRA, 4 of which are located in the Tidal Area. The Tidal Area Landfill, R-Area Disposal Site, and the Wood Hogger Site are wetlands hi the western portion of the Tidal Area contaminated from on-base waste disposal. The 20 acre site was a major disposal area from 1944 to 1979 and received an estimated 33,000 tons of waste. Materials and waste generated during the segregation of conventional munitions were discarded hi the R-Area Disposal Site. At the Wood Hogger Site, wood contaminated with pentachlorophenol (PCP) was chipped and placed hi an adjacent wetland. Another potential wetland area of concern is the Froid and Taylor Road site. Chemical analytical data identified hazardous substances including zinc, copper, cadmium, lead, arsenic, naphthalene, and methylene chloride, hi soil, sediment, or surface water. The Kiln Site and the K-2 Area are wetlands in the eastern portion of the Tidal Area. They were contaminated as a result of private sector industrial activities, and were subsequently purchased by the Navy to create a "buffer zone" for base operations. Soil sampling hi these areas in 1986 detected zinc, copper, lead, cadmium, and arsenic. High tides inundated the sources, carrying contaminants to Suisun Bay. Elevated levels of copper, zinc, lead, and arsenic were detected hi surface and composite soil samples hi the K-2 Area. The contaminated areas are critical habitats for the salt marsh harvest mouse, a Federally endangered species. The black California rail, a candidate Federally endangered species, and the California clapper rail, a Federally endangered species, inhabit adjacent wetlands. Suisun Bay supports extensive commercial and recreational fishing and is a habitat for the Whiter-run Chinook Salmon, also a Federally endangered species. Status (December 1994): Workplans for the Tidal and Inland Areas have been completed and approved. Field sampling occurred hi the Tidal Area hi 1994 and is planned for the Inland Area hi the spring of 1995. RCRA solid waste management units will also be sampled hi 1995. Those requiring clean up will be folded into the CERCLA remediation. The Navy conducted a removal of sediments hi the Litigation Area hi 1994. A post removal ecological assessment is also planned for 1995. [The description of the site (release) is based on information available at the time the site was scored.

DC 20460 December1994 DEL MONTE CORP. (OAHU PLANTATION) Honolulu County, Hawaii Conditions at Proposal (May 10, 1993): Del Monte Corp.'s Oahu Plantation occupies 6,000 acres in Honolulu County, Hawaii, near the small village of Kunia on the coastal plain of the Island of Oahu. The area surrounding the plantation is used mostly for agricultural and military purposes. Del Monte has cultivated pineapple on the plantation since the 1940s. In pineapple agriculture, fumigants are used to .control nematodes that infest the pineapple root. The dominant fumigant used at the plantation from the 1940s until 1983 was ethylene dibromide (EDB). During the spring of 1980, the Hawaii Department of Health (HDOH) began a program designed to determine whether the fumigants used in pineapple agriculture had contaminated drinking water wells on Oahu. As part of this program, the Del Monte Kunia well was sampled. The well is located on the Oahu Plantation and provided drinking water for the approximately 700 residents of Kunia. Analyses detected two fumigants, EDB and 1,2- dibromo-3-chloropropane (DBCP). On April 25, 1980, HDOH ordered the Del Monte Kunia well removed from service. Water from the contaminated well is sprinkled onto non-crop fields. Following the discovery of contamination, investigations by Del Monte, HDOH, and the Hawaii Department of Agriculture revealed two sources of contamination: an area used to store drums of fumigant from the 1940s until 1975, and an area near the well where 495 gallons of EDB spilled in 1977. Soils and ground water beneath these sources contained high concentrations of EDB and DBCP, according to over 400 analyses conducted between 1981 and 1991. Since the discovery of contamination at the Kunia well, Del Monte engaged in .remedial activities at the site, including the removal of 18,000 tons of soil, which was spread on a nearby field. Despite these actions, the Kunia well contains concentrations of EDB and DBCP that are greater than the Cancer Risk Screening levels for these two contaminants. Status (December 1994): Effective September 6, 1994, Del Monte voluntarily disconnected the Kunia Well from the non-crop irrigation system. Del Monte is working with EPA to develop and implement alternative treatment technologies and a ground water monitoring program. EPA is beginning the Remedial Investigation (RI) process to determine the extent of contamination at the site and will evaluate all existing site data to determine the need for a baseline risk assessment.

DC 20460 Dacember1994 ESCAMBIA WOOD-PENSACOLA Escambia County, Florida Conditions at Proposal (August 23, 1994): Escambia Wood-Pensacola is located at 3910 North Palafox Street, in a primarily low-income, minority area of Pensacola, Escambia County, Florida. The facility is an abandoned wood preserving plant which operated from 1942 until 1982. During its operational period the facility treated wood products with creosote and pentachlorophenol. Three open surface impoundments remained at the facility after its closure. Another backfilled surface impoundment was located in the northeast portion of the facility. In November 1980, Escambia Wood-Pensacola filed a RCRA Part A application, but there is no record of a RCRA Part B application for the facility. In 1986 the Florida Department of Environmental Regulation (FDER) determined that the backfilled surface impoundment was an unpermitted disposal area not regulated under RCRA. In 1990, a RCRA Facility Assessment was conducted at the facility, but the facility is no longer classified under RCRA. Sampling investigations were conducted at the facility by EPA in April 1982, FDER in September 1987, EPA in April and June 1991, and by EPA in May 1992. During the various investigations, pentachlorophenol and numerous other creosote constituents were detected at elevated concentrations in ground water samples. In addition, pentachlorophenol and several other organic and inorganic analytes were detected in numerous surface soil, subsurface soil, and sludge samples collected during the investigations. In 1985, Escambia Wood-Pensacola conducted a partial removal action that removed sludges from the three surface impoundments. A subsequent removal conducted in 1988 removed the contaminated wooden side walls of the two small impoundments. During both of these removal actions, the waste was taken off-site for proper disposal. In addition, approximately 220,000 cubic yards of contaminated soil have been excavated from two pits and stored in piles at the facility. The presence of an observed release to ground water at the facility indicates that hazardous substances were released prior to the initiation of removal activities at the site. The primary source of ground water in Escambia County is the Sand-and-Gravel aquifer, which lays beneath the facility. Approximately 20 public water supply and numerous private wells located within 4 miles of the Escambia Wood-Pensacola facility are completed within the Sand-and-Gravel aquifer and serve approximately 129,330 people. The nearest public supply well is located 1 mile northeast of the site. Status (December 1994): EPA has started a fund-lead Remedial Investigation and Feasibility Study (RI/FS) at the site. To enhance community involvement during the RI/FS process, EPA has established a Community Working Group for the site. Members will have an opportunity to comment on EPA documents and will serve as a conduit for disseminating information to the community at large.

DC 20460 December 1994 J FORT EUST1S (US ARMY) Newport News, Virginia Conditions at Proposal (January 18, 1994): Fort Eustis, owned and operated by the U.S. Department of the Army, occupies approximately 8,300 acres in southeastern Virginia, within the City of Newport News. The site is located on the western side of a low-lying peninsula formed by the York River and the James River estuaries, approximately 30 miles upstream of the confluence of the James River and the Chesapeake Bay. The facility is bounded on the west and south by the James River and to the east by the Warwick River, a large tributary of the James River. The James River is a major commercial fishing and recreational resource area. The site began operations in 1918 as a training center known as .Camp Abraham Eustis. In 1923, it became a permanent military installation renamed Fort Eustis. From 1931 to the early 1940s, Fort Eustis was operated by several nonmilitary Federal agencies for various uses. During World War II, it resumed military operations and was used for intensive antiaircraft training. In 1946, Fort Eustis became the Transportation Corps Training Center, providing training in rail, marine, and amphibian operations and other modes of transportation. Currently, Fort Eustis is the U.S. Army Transportation Training Center. Approximately 17,500 military personnel, their , dependents, and civilians live or work at the installation. t- In 1988, the U.S. Army Toxic and Hazardous Materials Agency identified 34 potential waste sources at Fort Eustis. The sources include unlined landfills, pesticide storage areas, firefighting training areas, maintenance shops, range and impact areas, and numerous other areas that were created as a result of operations. Sanitary landfills at Fort Eustis are currently undergoing closure. EPA initially evaluated seven sources based on documented releases of hazardous substances to surface water. Two of the sources are adjacent to Bailey's Creek, a 160-acre, low-lying wetland area used for fishing. Thirteen of the 34 identified sources are presently undergoing a Remedial Investigation/Feasibility Study. Sampling conducted in 1987 and 1990 indicated contamination of sediments from Bailey's Creek. The contamination included PCBs, chlordane, dichlorodiphenyldichloroethane (DDD), dichlorodiphenyldichloroethylene (DDE), DDT, and lead. Fish collected from Bailey's Creek contained PCBs. A sanitary landfill that received hazardous waste is located at the headwaters of Bailey's Creek. In addition, the Central Heating Fuel Spill Area, where waste oils were stored, is on a bluff overlooking the creek. Brown's Lake once was used as a drainage lagoon for the adjacent Helicopter Maintenance Area (HMA) and the upgradient Locomotive Area. The lake was used for recreation but was closed to water sports and fishing in the late 1970s by the Fort Eustis Preventive Medicine Group. A 1990 survey of Brown's Lake indicated that fish had lesions, ectoparasites, and skeletal deformities. Contaminants detected in the lake in 1987 included PCBs, pesticides, and polyaromatic hydrocarbons (PAHs). Sediment sampling in 1990 revealed contamination by PCBs and heavy metals in the lake and a tributary to the lake below the Locomotive Area. Surface drainage from Brown's Lake flows south through a sanitary landfill that is adjacent to the HMA and enters wetlands along the Warwick River and Milstead Island Creek drainage way. Both the Warwick River and Milstead Creek are used for fishing. In 1988, sampling in Milstead Island Creek found sediments contaminated with PAHs and pesticides. The site includes all the sources identified in the package and areas where contamination has come to be located. In addition, the site may include other sources and suspect areas later determined by EPA after NPL listing of the initial sources; conversely, if an area is later determined to be uncontaminated, it will not be included in the NPL site. Status (December 1994): EPA is currently considering various alternatives for the site. [The description of the site (release) is based on information available at the time the site was scored.

Since 1955, General Electric's Lighting System Division has manufactured various types of luminaire systems on a 50-acre property bounded by Tabor Road, Spartanburg Highway (U.S. 176), and Bat Fork Creek. On the GE property are a manufacturing plant, a warehouse, plots used for landspreading of wastes, two unlined waste treatment ponds, a sludge impoundment, landfills, and a recreation center. From 1957 to 1970, wastes from the General Electric (GE) facility were also disposed of approximately 2,500 feet to the southwest in an old dry pond or ravine known as Shepherd Farm. Wastes were brought to this 3-acre area and deposited, burned, then bulldozed. A trailer park is now located on a portion of the old dump site. Samples collected in May 1990 by EPA indicate primarily the same waste types and contaminants are present on Shepherd Farm and the GE property. GE wastes were also deposited on the Seldon Clark property located across Tabor Road from GE. GE wastes may also have been deposited in other nearby areas. Studies conducted by EPA, the State, and GE between 1976 and 1989 revealed that several inorganic compounds and volatile organic compounds (VOCs) had contaminated ground water and surface water sediments on and off both the GE property and the farm. A drainline that carried wastewater from the manufacturing plant to the treatment ponds had apparently ruptured. VOCs also contaminated 19 nearby private wells. Municipal water lines have been extended to these homes. The wastewater treatment ponds and sludge impoundment on site were found to be contaminated with PCBs and heavy metals. Among the compounds identified in on-site and off-site wells are tetrachloroethene, trichloroethene, 1,2- dichloroethene, cobalt, chromium, copper, lead, nickel, zinc, and manganese. An estimated 4,400 people formerly obtained drinking water from private wells within 4 miles of the site, the nearest 0.04 mile from the site. Soils in the trailer park contain PCBs, according to a 1991 EPA report. Status (December 1994): In June 1994, EPA Region 4 began a fund-lead Remedial Investigation and Feasibility Study (RI/FS). GE refused to sign the Administrative Order by Consent. Ground water, surface water, sediment and soil samples have been taken to determine the extent of contamination on the GE facility, the Shepherd Farm property and the Seldon Clark property. EPA plans to propose a clean-up alternative in late 1995. [The description of the site (release) is based on information available at the time the site was scored.

DC 20460 December1994 ICG ISELIN RAILROAD YARD Jackson, Tennessee Conditions at Proposal (May 10,1993): The ICG Iselin Railroad Yard (ICG Iselin) is located in Jackson, Madison County, Tennessee. The 80-acre site is situated at the intersection of Eastern Street and Magnolia Street in a predominately suburban area. From 1906 to 1940, the property was owned and operated by Mobile & Ohio Railroad Co. (M&O). According to a 1926 tax map for the City, the facility at one time included a round house, a steam locomotive fueling station, a coal-fired power plant, and the locomotive maintenance building. In 1940, M&O was sold to Gulf Mobile & Ohio Railroad Co., which reorganized in 1972 as the Illinois Central Gulf Railroad Co. (ICG). From 1972 to 1986 ICG used the site as a locomotive maintenance facility. The Williams Steel Co. purchased partial acreage in 1986, and used it as a steel fabrication facility until 1989. In that year, the property was transferred to its present owner Iselin Properties, Inc. through Campbell & Associates. The remaining acreage is owned by Norfolk Southern Railway Co. The ICG Iselin site includes a main warehouse; numerous railroad tracks; storage tanks; a pollution abatement system that includes a lye vat, a neutralization tank, several drainage ditches, a concrete tank, and a surface impoundment; a battery waste disposal pile; and a fueling platform under an open-air shed. Disposal practices at the site prior to 1972 are unknown. In 1973, ICG Iselin was issued a temporary National Pollution Discharge Elimination System (NPDES) permit for discharge into river mile 0.5 of Jones Creek, pending the construction and approval of a pollution abatement facility. In 1975 and in 1980, the facility reported that it exceeded its NPDES permit parameters for chromium. A 1990 investigation by the Tennessee Department of Health and Environment identified organic and inorganic constituents in surface soils. In 1991, the EPA conducted further sampling. Both investigations showed elevated levels of chromium, copper, and lead in surface soils. The 1991 investigation also identified vinyl chloride, chloroethane, tetrachloroethene, 1,1-dichloroethane, benzene, ethylbenzene, and xylenes in on-site sediments. The Jackson Utility Division supplies drinking water to approximately 31,000 people from 10 wells within 4 miles of the facility. Status (December 1994): The State of Tennessee has taken the role of lead agency for Remedial Investigation and Feasibility Study (RI/FS) activities. On June 6, 1994, the State issued a Commissioner's Order requiring the PRPs to perform a RI/FS for the site. The Potentially Responsible Parties (PRPs) are currently performing the RI/FS under State oversight. {The description of the site (release) is based on information available at the time the site was scored.

DC 20460 December 1994 KOPPERS CO., INC. (CHARLESTON PLANT) Charleston, South Carolina Conditions at Proposal (February 7, 1992): A milling, wood-preserving, and pole storage facility operated in the Charleston Heights District of Charleston, Charleston County, South Carolina, between 1925-78. Koppers, Inc. operated the facility between 1945 and 1978. The 102-acre site is in a mixed industrial/residential area. It is bordered on the west by Ashley River, and on the north and south by industrial facilities. Approximately 94,000 people live within 4 miles of the site. Sources of hazardous substances on the site include a pit where timbers were soaked in creosote wood preservative, the "drip pad area" where the timbers were stored, and a bermed area that received contaminated sediment from canal dredging on the site. Southern Dredging Co. leased part of the site in 1978 after wood-preserving operations had stopped. In 1984, the company dredged a canal from the Ashley River, intersecting a waste disposal area. Dredged materials were placed in the bermed area. EPA tests conducted in 1988 detected numerous polynuclear aromatic hydrocarbons (PAHs), which are constituents of creosote, in soil in all three sources. Runoff from all three sources enters the Ashley River. The 1988 tests found PAHs, chromium, copper, and zinc (metals typically used in wood preservatives) in sediment samples from the canal and the Ashley River. Wetlands are adjacent to the site, and wetlands to the west and southwest are a State wildlife sanctuary. The Ashley River and Charleston Harbor support recreational and commercial fishing, and serve as important breeding and nursery habitats for a variety of marine finfish and shellfish. Status (December 1994): Beazer East, Inc., formerly Koppers Co., entered into an Administrative Order by Consent with EPA Region 4 on January 14, 1993 for the performance of an Remedial Investigation and Feasibility Study (RI/FS) at the Site. The results of the RI are scheduled to be released to the public in early 1995. Interim Measures will also be proposed to the public at this time to mitigate off-site migration of the site contaminants from the former treatment area to surface waters and subsequently the sensitive Northern marsh areas.

The plant operated from 1900 to 1951 and was demolished in 1952. An electrical substation and small storage building currently occupy the southwest corner of the site. The remainder of the site is idle. Land use in the immediate vicinity consists of commercial and residential areas. The site is bounded to the east by South Pennsylvania Avenue, to the south by 5th Street Southeast, to the west by South Delaware Avenue, and to the north by a retaining wall along Willow Creek. During excavation activities for installation of a sewer line in 1984, oily sludges were encountered in subsurface soils at the site. Subsequent investigations conducted by the site owner, Interstate Power Co. (IPW), revealed the presence of three underground storage structures containing oily sludge. The three structures and their contents were excavated, along with contaminated soil from around the structures. The excavated material was stockpiled directly onto the ground near the southeast corner of the site, and is covered with a membrane cap. This waste pile is one of two sources of hazardous substances at the site. Contaminated soil is also present in the north-central portion of the site. Soil samples collected from soil borings indicated that contaminated soil is present to depths to 13.5 feet. The area of contaminated soil is the second source of hazardous substances. The site is situated on fill material consisting of sand, gravel, and construction rubble and debris, and is in direct contact with bedrock. Although the water table level fluctuates with precipitation, the water table in the fill material is typically present at depths ranging from 8 to 10 feet below land surface. A portion of the shallow ground water moving through the fill material and the upper portion of the bedrock discharges to Willow Creek. Well logs for the eight Mason City municipal drinking water wells, which are within 2 miles of the site, indicate that six of the wells are uncased through portions of the Cedar Valley aquifer. The Cedar Valley aquifer yields water to the municipal wells. Approximately 98 percent of the population of Mason City is supplied by the municipal drinking water supply. . The most significant contamination identified by a series of investigations conducted at the site between 1986 and 1989 by IPW, is the presence of polynuclear aromatic hydrocarbon (PAH) contamination in the on-site waste pile, on-site soil, bedrock and ground water beneath the site and Willow Creek, and in Willow Creek sediments. High concentrations of PAHs have been detected in samples of ground water collected from the uppermost aquifer, and in samples of Willow Creek sediment downstream from the site. Site characteristics indicated the potential for PAH-contaminated ground water in the uppermost aquifer to discharge to the surface water. Willow Creek is used for public recreational fishing. The site owner is conducting a Remedial Investigation and Feasibility Study (RI/FS) at the site under EPA oversight. Field activities within the RI/FS include the installation of additional ground water monitoring wells, and the collection and analysis of soil, sediment, surface water, and ground water samples. Status (December 1994): The FS is expected to be completed during the first quarter of fiscal year 1995. The Draft Engineering Evaluation/Cost Analysis (EE/CA) is under review at EPA in lieu of a Record of Decision (ROD). This is for the purpose of selecting a removal action. The planned completion date for the EE/CA is January 1, 1995. [The description of the site (release) is based on information available at the time the sites was scored.

Land in the area is primarily used for industrial, commercial, and residential purposes. In 1987, the Nebraska Department of Health (NDH) detected various chlorinated organic compounds in five of the nine municipal wells serving Ogallala. Subsequent investigations identified ten companies as possible sources of the ground water plume and more have been suggested. Two companies have been studied in some detail. Since 1987, American Shizuki Corp. has manufactured electrical components on an approximately IS-acre property at 301 West O Street. TRW, Inc., owned and operated the facility from the early 1960s through 1986. Operations involved various organic solvents, including trichloroethene (TCE) and 1,1,1-trichloroethane (TCA). Since the early 1960s, Ogallala Electronics has manufactured electronics components on two parcels of land covering about 1 acre at 601 West 1st Street. Its operations also involve TCE and TCA. A June 1990 Nebraska Department of Environmental Control (NDEC) soil-gas survey in Ogallala detected significant concentrations of TCE, TCA, and'other chlorinated organic compounds on the properties of both companies. In mid-1991, NDEC detected similar compounds.in monitoring wells in and around both properties, and in two Ogallala municipal wells. Earlier (1990), NDEC had detected similar compounds in six private wells. An estimated 5,100 people obtain drinking water from public and private wells within 4 miles of the site. Wells are also used for irrigation. The 1990 soil-gas survey had identified additional potential sources of the contamination of Ogallala's wells. They will be investigated in the Remedial Investigation/Feasibility Study that typically follows listing.

Onondaga Lake is approximately 4.5 miles long and averages 1 mile in width. Seven major tributaries flow into the lake; water exits the lake via a barge canal at its northwest end and flows into the Seneca River. The land immediately adjacent to the lake consists primarily of industrial properties and county parks. The site is composed of the lake itself, its tributaries and the upland hazardous waste sites which have contributed or are contributing contamination to the lake (sub-sites). A ban was placed on public fishing from the lake in 1970 due to high concentrations of mercury in several species of fish. The lake was re-opened to fishing in 1986 on a catch and release basis only. Population and industrial growth in the areas surrounding Onondaga Lake has resulted in extensive biological, chemical, and physical degradation of its waters. In addition to mercury contamination in the lake, analyses of sediment samples detected barium, cadmium, chromium, cobalt, lead, benzene, chlorobenzene, total xylenes, various polycyclic aromatic hydrocarbons, pesticides, and PCBs. Historical information indicates that the lake received surface water discharges from various industrial processes and municipal waste water treatment plants. Initially, the Environmental Protection Agency (EPA) has evaluated only operations of Allied Signal, Inc. (AS) and/or its predecessors, and Linden Chemicals and Plastics, Inc. (LCP), now owned by the Hanlin Group. EPA is attempting to identify additional potentially responsible parties. The AS facilities manufactured numerous organic and inorganic chemicals. AS's Willis Avenue plant and LCP's Bridge Street plant (located west of the Main Plant complex), used a mercury cell process to produce chlorine, sodium hydroxide, and potassium hydroxide. Each plant discharged aqueous waste streams containing mercury as part of normal operations. Other waste sources include AS's Solvay Waste Beds containing by-products generated from soda ash production and Semet Residue Ponds containing wastes generated from acid washing of light oil. Several consent orders have been signed in recent years between AS and the New York State Department of Environmental Conservation (NYSDEC) related to the Solvay Waste Beds, the Semet Residue Ponds and ground- water contamination at the location of the Willis Avenue Plant. In early 1992, AS and the NYSDEC signed a consent decree to perform a Remedial Investigation/Feasibility Study (RI/FS) to determine the type and extent of contamination at Onondaga Lake and to identify alternatives for remedial action. NYSDEC has also filed an action against the Hanlin Group under Subtitle C of the Resource Conservation and Recovery Act (RCRA). The Hanlin Group commenced bankruptcy proceedings on July 10, 1991. Status (December 1994): Presently, AS is performing the Onondaga Lake RI/FS and RI/FSs for the Solvay Waste Beds, Semet Residue Ponds, and Willis Avenue Plant. EPA has entered into a cooperative agreement with NYSDEC to provide funds so that NYSDEC can coordinate, manage, and oversee the ongoing work at the subsites and prepare a comprehensive RI/FS for the Onondaga Lake NPL site. NYSDEC, together with EPA, has started mailing information request letters to companies located in the Onondaga Lake watershed in an attempt to identify other potentially responsible parties.

The primary activity at MCRD is the training of Marine Corps recruits. The facility covers more than 8,000 acres, including more than 4,000 acres of salt marsh and tidal streams. Numerous potentially hazardous waste sites have been identified at the facility. The Incinerator Landfill and the Borrow Pit Landfill are located on Horse Island. The unlined Causeway Landfill was constructed across Ribbon Creek, a tidal stream and marsh between Parris Island and Horse Island. Wastes known to be disposed in landfills at MCRD include empty pesticide containers, oil contaminated with polychlorinated biphenyls (PCBs), and mercury amalgam. In addition, from 1950 until 1978, rinsewaters from pesticide application containers and equipment were disposed in a dirt or grassy area (Pesticide Rinsate Disposal Area) located between Quonset huts N282 and N277. MCRD conducted an Initial Assessment Study (IAS) in 1986. Of the 16 areas evaluated during the IAS, 6 were recommended for further confirmation studies. In February and March 1988, MCRD conducted sampling activities at the facility as part of the Remedial Investigation Verification Step. Mercury, lead, and other inorganic analytes were detected in surface water and sediment samples collected from the streams and marshland located adjacent to the Causeway Landfill. In 1991, EPA conducted an Expanded Site Inspection at the Causeway Landfill. Numerous organic analytes, including PCB-1254, were detected in tissue samples from oysters collected from the tidal waters located adjacent to the Causeway Landfill. The average concentrations of several organic analytes in oyster tissue samples collected were higher for samples from an impoundment on the northeast side of the Causeway Landfill than for samples collected from the southwest side. A release was documented based on evidence that hazardous substances were deposited directly into Ribbon Creek and adjacent tidal marshes. The presence of hazardous constituents in surface water, sediment, and tissue samples collected from Ribbon Creek, adjacent to the Causeway Landfill, demonstrate adverse effects associated with the release to surface water. Surface water runoff from MCRD enters salt marshes and streams which surround Parris Island. Several bodies of water located within 15 miles downstream of MCRD, including the Causeway Landfill impoundment and the Broad River, are used for fishing. Extensive estuarine wetlands and nesting areas for the loggerhead turtle are present within 15 miles downstream of MCRD. All residents within 4 miles of the source areas normally obtain drinking water from the Beaufort-Jasper Water and Sewer Authority (BJWSA). BJWSA obtains water from a surface water intake located on the Savannah River which is not affected by runoff from the facility. Status (December 1994): Federal Facility Agreement (FFA) Negotiation start is planned for the third quarter of fiscal year 1995. EPA, SC-DHEC, the Marine Corps, and the Navy are in the process of forming an Installation Restoration Team and have initiated scoping the Remedial Investigation, developing a Site Management Plan, and initializing funding requests from the Defense Environmental Restoration Account (DERA) for anticipated environmental clean up work. A Restoration Advisory Board Implementation plan is being developed to get community involvement early in the Superfund process at MCRD Parris Island.

The northern section of the landfill has been graded and is now occupied by a trucking firm. The area is residential and commercial. Buffalo International Airport is approximately 0.5 mile west of the site. Chemical wastes in liquid, solid, and sludge form were either buried at the site in drums or placed into cells excavated in the ground. The wastes deposited included cyanides and plating sludge, waste paint and paint sludge, lithographic inks, pigments, organic solvents, liquid and solid PCB-contaminated wastes, sludge from distillation processes, petroleum wastes, and 100 to 125 tons of phenol tar containing chlorinated benzenes and dioxins. Since 1980, the Erie County Health Department, EPA, the New York State Department of Environmental Conservation (NYSDEC), and the owner have investigated the site. A remedial investigation was conducted in 1988-89 by NYSDEC. The investigations indicated that surface water both on and off the site is contaminated by organic chemicals, including benzene, phenol, chlorobenzene, and dichlorobenzene. Nearby surface water consists of Ellicott Creek, an adjacent ditch that leads into the creek, and Aero Lake, which lies just north of the ditch. The lake and creek are used for recreational fishing. A wetland formerly existed in what is now the central section of the property. Other wetlands border the creek and ditch. On-site and off-site soil is contaminated with PCBs, barium, manganese, and mercury, according to the remedial investigation. Most of the site is fenced, but drainage ditches contaminated with leachate from the landfill lie outside the fencing and are accessible to the public. Ten homes are within 200 feet of an area of contaminated soil. Status (December 1994): Currently, the potentially responsible parties (PRPs) are preparing the design for the landfill cap, even though a Consent Order has not been officially signed with DEC. EPA will be reviewing all design documents. Additionally, the Agency for Toxic Substances and Disease Registry (ATSDR) has announced that it will be collecting attic dust samples from homes adjacent to the landfill, as well as some further away to be used for control purposes. ATSDR is currently preparing the sampling protocol, which will be reviewed by EPA and DEC. The sampling is expected to take place in early 1995.

DC 20460 Decembaf1994 REYNOLDS METALS Troutdale, Oregon Conditions at Proposal (August 23, 1994): The Reynolds facility is a primary aluminum reduction plant where alumina from bauxite is reduced to aluminum. The facility is approximately 1.25 miles north of the City of Troutdale, Oregon. The Columbia River forms its northern border and the Sandy River forms its eastern border. A dike surrounds the plant on the northern and eastern sides, and protects the plant from floods. Site areas north and east of the dike are within the 100-year flood plain. The plant was completed in 1941 for the United States government war-time operations. Reynolds first leased the plant from the government in June 1946, and purchased it in June 1949. Currently, Reynolds owns the 80.25-acre plant area and approximately 500 surrounding acres. The aluminum reduction plant has been shut down since November 1991 for economic reasons. Currently, there are approximately 100 workers for maintenance, security, administration, and casting ingots from molten aluminum transported to the plant from the Reynolds reduction plant in Longview, Washington. Large quantities of wastes were produced at the Reynolds plant during the production of aluminum. Twenty-one separate waste streams were identified by Reynolds in response to an EPA information request letter. Major hazardous substances of concern include polyaromatic hydrocarbons (PAHs), aluminum and other metals associated with bauxite, cyanide, fluoride, and polychlorinated biphenyls (PCBs) from electrical equipment. In May 1993, an EPA contractor collected samples at the Reynolds site. On-site sampling included surface and subsurface soil, sediment, surface water, ground water and an unknown waste pile. Elevated concentrations of cyanide, PAHs, many metals, and fluoride were detected in various sources on site. Elevated levels of cyanide and fluoride were detected in several on-site drinking water wells. Significant concentrations of aluminum, barium, manganese, cyanide, and fluoride were detected in the surface water samples. Concentrations of copper and cyanide in an on-site drainage ditch which flows to an on-site lake and then the Columbia River exceeded the freshwater quality criteria promulgated under the Clean Water Act. Elevated concentrations of fluoride, metals, and extremely .high concentrations of PAHs were detected in sediment samples taken from the ditch and lake. The same contaminants were also detected in on-site wetlands. The Columbia and Sandy Rivers are used for recreation and fishing, people reach the rivers through the Reynolds property. Anadromous fish are found in both rivers as well as numerous sensitive environments. The Reynolds Metals Company (RMC) has expressed an interest in investigating and conducting early actions under the EPA Removal Program. RMC has initiated an integrated assessment under EPA oversight. The scheduled seven week assessment is the first phase of investigations and is a cooperative effort between RMC and EPA. On- site ground water contamination and newly discovered dump sites are being characterized and evaluated for expedited response actions. Status (December 1994): RMC completed field work in summer of 1994 which will help determine time-critical actions, non-time-critical actions, and further investigations to be conducted at the site. [The description of the site (release) is based on information available at the time the site was scored. The description may change as additional information is gathered on the sources and extent of contamination.
