Sites are arranged alphabetically by State and by site name. The size of the site is generally indicated based on information available at the tine 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. Rpmpriial Actions Under Superfund The Superfund program is authorized by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERdA) and the Superfund Amendments and Reauthorization Act (SARA), enacted en October 17, 1986. Under SARA, the Hazardous Substances Superfund pays the costs not assumed by responsible parties for cleaning up hazardous waste sites or emergencies that threaten public health, welfare, or the environment. The Superfund program is managed by the U.S. Environmental Protection Agency (EPA). Two types of responses may be taken when a hazardous substance is released (or threatens to be released) into the environment: o Removal actions, emergency-type responses to inminent threats. SARA limits these actions to 1 year and/or $2 million, with a waiver possible if the actions are consistent with remedial actions. Removal actions can be undertaken by the private parties responsible for the releases or by the Federal Government using the Superfund. o Remedial responses, actions intended to provide permanent solutions at abandoned or uncontrolled ba?artv»tq waste sites, ppmpdj^l responses are generally longer-term and more expensive than removals. A Superfund remedial response can be taken only if a site is on the NPL. After publishing two preliminary lists and proposing a formal list, EPA published the first NPL in September 1983. The list must be updated at least annually. The money for conducting a remedial response or removal action at a hazardous waste site can come from several sources: o The individuals or companies responsible for the problems can clean up voluntarily with EPA or State supervision. o The responsible party or parties can be forced to clean up by Federal or State legal action. o A State or local govt clean up without Federal dollars. nt can choose to assume the responsibility to U.S. Environmental Protection Agency Hogion 5, Library (i/?T. 1C-} 2"0 S. Dearborn St:->:c';, 't::i 1C70 (.": lO'13'O, JL U1 -0-i ------- o Superfund can pay for the cleanup, then seek to recover the costs fron the responsible party or parties. A remedial response under Superfund is an orderly process that generally involves the following Steps: o Take any measures nrodod to stabilize conditions, which might involve, for example, fencing the site or removing above-ground drums or bulk tanks. o Undertake initial planning activities to scope out a strategy for collecting information and analyzing alternative courses of action. o Conduct a remedial investigation to determine the type and extent of contamination at the site. o Conduct a feasibility study to analyze various cleanup alternatives. The feasibility study is often conducted with the remedial investigation as one project. Typically, the two together cost $1 million and take from 9 to 18 months to complete. o Select the cleanup alternative that: — Protects human health and the environment — Attains Federal and State requirements that are applicable or relevant and appropriate — Makes maximum use of permanent solutions, alternative treatment technologies, or resource recovery technologies — Is "cost effective" — that is, the results achieved are proportional to the cost (tentative working definition) o Design the remedy. Typically, the design phase costs $750,000 and takes 6 to 12 months. o 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. The implementation phase typically lasts 6 to 12 months. The State government can participate in a remedial response under Superfund in one of two ways: o 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 condition* in the cooperative aymanent are met. In contrast to a grant, EFA continues to be substantially involved and monitors the State's progress throughout the project. ------- o EPA can take the lead under a Superfurd State Contract, with the state having an advisory role. EPA, generally using contractor support, manages work early in the planning process. In the later design and implementation (construction) phases, contractors do the work under the supervision of the U.S. Amy corps of Engineers. Under both arrangements, the State oust share in the cost of the Implementation phase of cleanup. EPA expects this phase to average out at about $13.5 million per site, plus any costs to operate and maintain the remedial action. ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended in 1986 ARCTIC SURPLUS Fairbanks, Alaska The Arctic Surplus Site covers 22 acres in the southeast part of Fairbanks, Alaska. The site is bounded to the north by a residential subdivision, to the south by the Alaska Railroad, to the west by Fort Wainwright, and to the east by low-density residential property. On-site are a variety of buildings, storage trailers, and disremied military equipment. Salvage operations at the site were conducted from 1946 to 1976 by a number of parties, including the Department of Defense. Approximately 3,500 to 4,000 drums are visible on-site. They contain unknown quantities of various oils, fuels, and chemicals; many drums are leaking. Other wastes on- site include unknown quantities of asbestos rolls, batteries and battery acid that was drained onto the ground during battery recycling activities, and ash piles from incineration of transformer casings. In September 1988, contractors for the Alaska Department of Environmental Conservation conducted a site inspection and detected significantly elevated levels of lead, zinc, PCBs, phenanthrene, pyrene, and copper in on-site soils. Ground water beneath the site is shallow and contains elevated levels of lead and zinc. Over 12,000 people obtain drinking water from wells within 3 miles of the site. In May and June 1989, EPA emergency staff aaooosod the site to determine if a removal action is warranted. A drum inventory showed approximately 1,700 drums contained liquids or sludges, some flammable or corrosive. Chlordane, a very toxic pesticide, was detected in soils at a concentration as high as 320,000 parts per million. EPA started a removal action in September 1989 to stabilize the site and prevent unauthorized access. Leaking drums were overpacked, loose ashftstms was stabilized, and a chainlink fence was erected. Additional activities are anticipated for the spring and summer of 1990. U.S Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response. Compensation, and Liability Act (CERCLA) as amended m 1986 MAGNOLIA CITY LANDFILL Magnolia, Arkansas Magnolia City Landfill comprises two 40-acre tracts (one of which has not yet been used) located 2.3 miles south of Magnolia, Arkansas, in Colombia County. The area around the site is forested, with some residences. The city has owned and operated the site since 1955, accepting residential and commercial trash, as well as industrial wastes, from the area. During 1955-65 and 1970-79, 56,100 gallons of solvents and other organic chemicals from Firestone Coastal Fabrics Co. in Magnolia were burned and the residue buried at the landfill, according to information the company supplied to EPA as required by CERCLA Section 103(c); an additional 40,000 gallons were also buried. Since 1971, Alumax Magnolia Division (formerly known as Hownet Aluminum Corp. of Magnolia) has deposited about 31,200 cubic yards of aluminum hydroxide sludge containing small amounts of phenolic glue and nickel, according to information the company provided to EPA. An EPA inspection in September 1986 revealed that a large quantity of sludge was being spread evenly on a portion of the landfill. In 1987-88, EPA found benzene, trans-l,2-dichloroethylene, and trichloroethylene in on-site monitoring wells. An estimated 200 people obtain drinking water from private wells within 3 miles of the landfill. EPA tests conducted in February 1988 identified lead and nickel in . on-site soil. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended in 1986 MONROE AUTO EQUIPMENT OO. (PARAGOUID PIT) Paragould, Arkansas The Monroe Auto Equipment Go. Pit covers 4 acres including a 1-acre disposal area on Finch Road in Paragould, Greene County, Arkansas. The area around the site is rural. In 1973, the company received temporary approval from the Arkansas Department of Pollution Control to dispose of electroplating sludges into a pit that had formerly been mined for sand and gravel. The company says that during 1973-78 it buried approximately 15,400 cubic yards of sludge containing iron, nickel, chromium, and zinc in the pit. The sludges also contained trichloroethylene and 1,1,1-trichloroethane used as degreasers during the electroplating process. On-site monitoring wells and a private drinking water well 300 feet southeast (downgradient) of the pit are contaminated with 1,1-dichloroethane and 1,2-dichloroethylene, according to tests conducted in 1987-88 by the Arkansas Department of Health and a Monroe consultant. The consultant also found arsenic, nickel, and lead in the monitoring wells. An estimated 2,100 people obtain drinking water from private wells within 3 miles of the site. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed ur.der the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended m 1986 INDUSTRIAL WASTE PROCESSING Fresno, California Industrial Waste Processing (IMP) occupies approximately 0.5 acre at 7140 North Harrison Street in Fresno, Fresno County, California. The area is primarily residential, with some light industrial commercial operations. During 1957-81, IWP principally recycled solvents and lead solder. During 1977-83, IWP operated as a distributor for Ashland Oil. Since 1983, the site has been used solely for storage of chemicals and equipment. During an inspection in June 1988, EPA observed piles of waste lead solder flux and leaking asbestos bags stored on bare ground, and glycols and chlorinated solvents stored in open and leaking drums. EPA analysis of on- site soil identified numerous compounds, including lead, trichloroethylene (TCE), perchloroethylene (PCE), dichloroethylene (DCE), 1,1,2,2- tetrachloroethane (PCA), and 1,1,1-trichloroethane (TCA). EPA has designated Fresno County Aquifer, which underlies the Fresno area, a sole source aquifer under the Safe Drinking Water Act. Three municipal water systems have a total of 83 supply wells within 3 miles of IWP that draw from the Fresno County Aquifer. As of November 1988, at least 13 of these wells contained organic solvents, including TCE, PCE, and DCE, according to EPA tests. In May 1988, Pinedale County Water District Well #3 was closed due to contamination by organic solvents. The well, which is the closest municipal well to IWP (within 0.25 mile directly downgradient), had 390 parts per billion, the highest concentration of TCE detected to date. One active well within 2,000 feet of IWP supplies water to the Nelson Elementary School. Municipal supply wells within 3 miles of IWP are part of a distribution system that serves over 300,000 people in the Fresno area. In August 1988, EPA useu CERCLA emergency funds to remove all surface wastes at the site and the top 2 inches of soil. The materials were transported to a hazardous waste facility regulated under Subtitle C of the Resource Conservation and Recovery Act. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response. Compensation, and Liability Act (CERCLA) as amended in 1986 UNITED HECKATHORN CO. Richmond, California The United Heckathorn Co. Site occupies 13.5 acres adjacent to the Lauritzen Canal at 402 Wright Avenue in Richmond, Contra Costa County, California. The canal is on the Richmond Inner Harbor, which is on San Francisco Bay. The area is primarily light industrial with some residential development. From 1948 through 1965, several companies leased the site to process chemicals. The owners have been: from 1947 through 1961, Parr Industrial Corp.; from 1961 through 1981, Parr Richmond Terminal Corp.; and from 1981 through the present, Levin-Richmond Terminal Corp. (LRTC). In the late 1940s and early 1950s, Universal Pigment and Chemical Co. produced napalm on-site. From 1958 to 1965, Montrose Chemical Corp. contracted with United Heckathorn, United Chemetrics, and ChemWest for DDT-grinding services. These companies were tenants on the site during this period. United Heckathorn Co. was the last company to formulate pesticides at this site (1957-1965). Current site operations involve metal recycling. The California Department of Fish and Game has recorded several instances of chemicals being discharged into the Lauritzen Canal, including naphthenic acid in 1951 and DDT in 1960, which resulted in the death of 180 striped bass. In August 1980, the California Department of Health Services (CDHS), under its Abandoned Site Project, inspected the site and found elevated levels of DDT, lindane, BHC, aldrin, and other pesticides in nine soil samples. In early 1983, LRTC hired a consultant to study on-site DDT contamination. Soils were found to contain DDT and xylene, and sediments from the canal contained DDT. During the study, parts of the site were covered with 6 to 8 inches of crushed rock. LRTC's Site Characterization Plan was not approved by CDHS, however, so CDHS is conducting its own investigation of soil and ground water contamination. The Richmond Inner Harbor is used for recreational and commercial fishing and shellfish harvesting, as well as other recreational activities. A coastal wetland is less than 0.5 mile from the site. The harbor is part of San Francisco Bay, which the Water Quality Act of 1987 declared to be an estuary of national significance. In July-August 1988, EPA detected DDT in the atmosphere at numerous locations on and off the site. An estimated 10,900 people live within 1 mile of the site. U S Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended in 1986 WESTERN PACIFIC RAILROAD CO. Oroville, California Western Pacific Railroad Co. operated a 90-acre rail yard from approximately 1920 to 1983 at a location 2 miles south of Oroville, Butte County, California. Union Pacific Co. purchased the facility in January 1983. On the facility was a wooden structure encompassing approximately 3 acres, known as the round house, which was used to fuel, repair, service, and clean railcars. Specific activities conducted at the roundhouse included sandblasting, welding, cutting, and fabricating. As a result of these activities, waste solvents, oils, grease, and waste waters containing heavy metals were discharged to an unlined surface impoundment until October 1987. In October 1985, the California Department of Health Services (CDHS) detected arsenic, barium, copper, nickel, and chromium in soil and sludge in the impoundment. Chromium also was detected in a monitoring well adjacent to the impoundment. In addition, a consultant to CDHS found benzene and toluene in soil and sludge in the impoundment in August and October 1987. The California Regional Water Quality Control Board (CRWQCB) is investigating the site. According to CRWQCB, ground water occurs at 30 feet and is connected to deeper ground water that is a source of drinking water; soils are permeable. These conditions facilitate movement of contaminants into ground water. Four California Water Service Co. wells are within 3 miles of the site. Water from the wells is blended with water from Feather River to serve the company's 10,000 customers. One of the wells is on the site and is leased from Western Pacific. Between 1984 and 1986, California Water Service detected dichloroethylene in the well. Feather River is 1 mile from the site in the direction surface water drains. The river is used for recreational activities. In January 1989, CRWQCB issued a Cleanup and Abatement order to Union Pacific and Salano Railcar, which has leased 5 acres of the site from Union Pacific since 1970. The work called for includes sampling of abandoned water supply wells to determine the best way to seal them, installation of a water separator to collect run-off from locomotives, and installation of equipment to prevent run-off. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended in 1986 NEW LONDON SUBMARINE BASE New London, Connecticut The New London Submarine Base covers 1,412 acres on the east bank of the Thanes River, New London, New London County, Connecticut. The area around the base is mixed industrial, ccmnercial, and residential property. Established in 1916, the base serves primarily as an operation and support base for submarine activities in the Atlantic Ocean. The base is participating in the Installation Restoration Program (IRP), established in 1978. Under this program, the Department of Defense seeks to identify, investigate, and clean up contamination from hazardous materials. Under IRP, the Navy has identified 16 potential hazardous waste djppngai areas and has extensively studied three areas. Fran 1957 to 1973, volatile organic compounds, pesticides, PCBs, spent battery acids, and other waste were buried below the water table in the 25- acre Area A Landfill, located on base wetlands. The second area currently being investigated is the Defense Property Disposal Operations (DPDO) area, which was used as a burning ground and landfill from 1950 to 1969. The third area is the Over Bank Disposal Area (OBDA), which operated from 1957 to the 1970s. According to Navy tests conducted in 1984, sediment and surface water in and around Area A are contaminated with lead, cadmium, 4,4'-ODD, and 4,4'-DDT. Ground water in some areas is as shallow as 10 feet below the surface, and soils are permeable. These conditions potentially threaten ground water, which provides drinking water to 3,500 to 5,000 people within 3 miles of the base. U.S Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended in 1986 KOPPERS CO., INC. (NEWPORT PLANT) Newport, Delaware Koppers Co., Inc., operated a wood preserving plant from 1940 to 1971 on a 317-acre site at the corner of Water Street and Jones Street in Newport, New Castle County, Delaware. The site is bounded by rivers, creeks, and the Newport plant of E.I. Du Pont De Nemours & Co., Inc. In 1971, Koppers sold the site to Dupont. As part of the sales agreement, Koppers removed chemicals in the process tanks. Dupont removed all structures from the site, which is now vacant. The treatment process Koppers. used consisted, of loading railroad ties and telephone poles into cylinders and pressure injecting them with creosote or a mixture of no. 2 fuel oil and pentachlorophenol. In the treatment area were a pond filled with water used for fire protection and a sump where any effluent from the treatment process was collected. In December 1984, EPA detected polynuclear aromatic hydrocarbons (PAHS), such as benzo(a)anthracene, pyrene, fluoranthene, chrysene, and benzo(a)pyrene, in on-site soil, as well as in nearby creek sediment samples. These compounds are constituents of creosote. Ground water is the most important source of drinking water in the area. The Artesian Water Co. draws drinking water from three wells within 3 miles of the site and blends it with other water to serve its 150,000 customers. The wells tap the Lower Potomac Formation, which consists of permeable deposits and is hydraulically connected to the overlying Columbia Formation, permitting water to move between them. Approximately one-third of the site is wetlands, and additional wetlands border the site. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended in 1986 ANACONDA ALUMINUM CO./MILGO ELECTRONICS CORP. Miami, Florida The Anaconda Aluminum Co./Milgo Electronics Corp. Site consists of two areas located directly across from each other on N.W. 76th Street in Miami, Dade County, Florida. The site is in an industrialized area northeast of Miami International Airport. The Anaconda Aluminum portion of the site covers approximately 1 acre at 3610 N.W. 76th Street. Between May 1957 and February 1983, operations involved an electrochemical process using acids and an aluminum-containing base to produce a protective coating on aluminum. Up too 1967, a chromic acid process was employed. The Milgo Electronics portion of the site covers approximately 0.5 acre at 3601 N.W. 76th Street. Between 1961 and June 1984, operations involved chrome, nickel, and copper electroplating of data processing equipment and the manufacturing of cabinets for electronic components. Both companies disposed of liquid waste on-site. Anaconda Aluminum used soakage pits, while Milgo Electronics used a drainfield. In April 1987, EPA found chromium and lead in the Biscayne Aquifer, which EPA has designated as a sole source aquifer under the Safe Drinking Water Act. At least four municipal well fields are within 3 miles of the site: the Upper and Lower Miami Springs, the Hialeah, and the John E. Preston. An estimated 750,000 people obtain drinking water from wells within 3 miles of the site. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended m 1986 MIG/DEWANE LANDFILL Belvidere, Illinois The MIG/Dewane Landfill covers 50 acres on Business Route 20E in Belvidere, Boone County, Illinois. The site is in a rural area with commercial and agricultural operations nearby. Since 1976, MIG/Dewane has accepted household refuse and special wastes such as paint sludges and organic solvents. Approximately 480,000 gallons of hazardous waste containing arsenic, cadmium, lead, nickel, and cyanide were dumped into the landfill, according to the Illinois Environmental Protection Agency. In June 1986, EPA found 1,1-dichloroethane in on-site monitoring wells into the upper sand and gravel aquifer. The site is located near Belvidere's municipal water wells and private wells. One municipal well and 28% of the private wells are obtaining water from the upper sand and gravel aquifer. There is no confining layer to prevent migration of contaminants from the landfilled area to the upper aquifer. An estimated 16,300 people obtain drinking water from wells within 3 miles of the site. A private well is 2,500 feet from a contaminated well on the site. In 1985, the State Attorney General, on behalf of Boone County, filed a lawsuit against MIG/Dewane because the corpany was expanding the landfill beyond its permit. After the suit went to the Illinois Supreme Court, the site was ordered closed in June 1988. It ceased operations in July 1988. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response. Compensation, and Liability Act (CERCLA) as amended in 1986 DAKHUE SANITARY LANDFILL Cannon Falls, Minnesota The Dakhue Sanitary Landfill covers 80 acres approximately 3.5 miles north of Cannon Falls in a rural agricultural area of Dakota County, Minnesota. Since 1971, Dakhue Landfill, Inc., has had a permit from the Minnesota Pollution Control Agency (MPCA) to accept municipal wastes. MPCA estimates that through 1986, 817,000 cubic yards of solid waste (primarily nonhazardous industrial and municipal wastes) have been disposed of at the landfill, which has no liner. MPCA analyses in 1985 and 1987 of shallow monitoring wells on the site detected volatile organic compounds, including 1,1-dichloroethylene, tetrachloroethylene, methylene chloride, cis-l,2-dichloroethylene, and chloroform. The shallow ground water is used for drinking water by about 600 residents within 3 miles of the site and for irrigation of an estimated 6,500 acres. The nearest drinking water well is about 1,200 feet from the site. The area near the landfill consists of gently rolling hills sloping toward the south. Pine Creek is 1 mile south of the site, and Cannon River is nearly 3 miles to the south. In May 1980, MPCA issued Dakhue Sanitary Landfill a Notice of Noncompliance for failure to follow established operating procedures and failure to submit water monitoring reports. In November 1984, MPCA issued a Notice of Violation for failure to submit work required by the landfill permit. In June 1987, Dakhue Landfill, Inc., declared bankruptcy under Chapter 7 of the Federal bankruptcy code. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended in 1986 WESTLAKE LANDFILL Bridgetcn, Missouri Westlake Tqp^f 1.11 covers 200 acres in Bridgetcn, St. Louis County, Missouri, about 16 miles northwest of downtown St. Louis. The area is adjacent to prime agricultural land and is in the floodplain of the Missouri River. Between 1939 and the spring of 1987, limestone was quarried on the site. Starting in 1962, portions of the property were used for landfilling of solid and liquid industrial wastes, municipal refuse, and construction debris. In 1973, Cotter Corp. disposcri of over 43,000 tons of uranium ore processing residues and soil in two areas covering a total of 16 acres of the WestlaJoa landfill, according to a Nuclear Regulatory Commission (NRC) report published in 1977. In 1976, the Missouri Department of Natural Resources (MENR) closed the unregulated landfill. Since then, MENR has issued several permits for various portions of the 200-acre site. Currently, an operating sanitary landfill has a permitted area of 52 areas, and an operating demolition landfill has a permitted area of 22 acres. Uranium was detected in on-site monitoring wells in tests conducted in 1985 and 1986 by a consultant to the owner of the landfill. An estimated 60 people obtain drinking water from private wells within 3 miles of the site. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site fisted under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended in 1986 10TH STREET SITE Columbus, Nebraska The 10th Street Site consists of four contaminated municipal water supply wells and two areas of soil contamination in the City of Columbus, Platte County, Nebraska. The site occupies about 18 acres in downtown Columbus on the north bank of the Loup River. The site boundary is defined by Columbus Municipal Wells #1, 2, 4, and 11 and by four soil samples. These four municipal wells were sampled by the Nebraska Department of Health in June 1984 and December 1988 and by EPA in April 1987, September 1987, and February 1988. The results show from 2.0 parts per billion (ppb) to 29.0 ppb of 1,1,2-trichloroethylene. Tetrachloroethylene was detected in Wells 12 and #4 at levels ranging from 2.0 ppb to 24.7 ppb. A soil-gas survey conducted in May 1988 by EPA delineated a ground water plume with a point source located in a city parking lot (formerly a scrap metal yard) about 1,000 feet east of Well II. Among potential sources of the soil contamination are a dry cleaning facility behind the lot and a laundromat 1,400 feet southwest of the lot. Both facilities are or once were identified under Subtitle C of the Resource Conservation and Recovery Act as small quantity generators of waste containing tetrachloroethylene. Both facilities are within 1,000 feet of the contaminated wells. The municipal wells and private wells within 3 miles of the site provide drinking water to an estimated 19,300 people; 48 irrigation wells are also in use. All wells tap the surficial aquifer consisting of alluvial sands and gravels; the water table is at a depth between 12.4 and 30 feet. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response. Compensation, and Liability Act (CERCLA) as amended in 1986 NEBRASKA ORDNANCE PLANT (POWER) Mead, Nebraska The former Nebraska Ordnance Plant once occupied over 17,000 acres near Mead in a rural part of Saunders County, 35 miles northeast of Lincoln, Nebraska. From 1942 to 1956, the primary function of the plant was munitions production at four bomb loading lines for both World Mar II and the Korean conflict. The plant also was used for munitions storage and ammonium nitrate production. Some of the operations used organic solvents. Beginning in 1962, portions of the former plant were sold to various other entities. Today, the major production area of the former plant, approximately 9,000 acres, belongs to the University of Nebraska and is used as an agricultural research station. The remaining acreage currently is owned by the Nebraska National Guard and numerous individuals and corporations. The former Nebraska Ordnance Plant is being investigated by the U.S. Army Corps of Engineers as part of the Defense Environmental Restoration Program. The site, however, is not currently owned by the Federal government. Included in the Corps investigation are the current university property, the current Nebraska National Guard property, and the former administration area, bomb booster assembly area, burning ground/sewage treatment area, and ammonium nitrate plant. In a study completed in April 1989, the Corps identified areas of soil contaminated by PCBs and munitions wastes, including TOT and RDX. The Corps also detected TNT, RDX, and trichloroethylene (TCE) in on-site monitoring wells, and RDX and TCE in off-site drinking water wells. An estimated 400 persons obtain drinking water from wells within 3 miles of the site. Ground water also is used for irrigation and livestock. The Corps is conducting a remedial investigation to determine the type and extent of contamination in all known areas of contamination. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended in 1986 CHEMICAL INSECTICIDE CORP. Edison Township, New Jersey The Chemical Insecticide Corp. (CIC) Site covers approximately 5.8 acres directly south of Interstate Route 287 at 30 Whitman Avenue, Edison Township, Middlesex County, New Jersey. CIC manufactured, formulated, and distributed pesticide products on this property from 1958 to 1970, at which time the company declared bankruptcy and operations ceased. The site is vacant and enclosed by a 6-foot chainlink fence. Industrial properties surround the site, and residential developments are within 1 mile to the northeast and southwest. CIC produced a wide range of insecticides, fungicides, herbicides, and rodenticides. Waste disposal practices are not clearly documented. However, three surface impoundments were known to have existed at the site. The hazardous substances found at the site include carbon disulfide, ethylbenzene, chlorobenzene, beta-benzene hexachloride (beta-BHC), alpha-BHC, delta-BHC (lindane), gamma-BBC, dichlorodiphenyldichloroethylene (4,4-DDE), dichlorodiphenyltrichloroetnane (4,4-DDT), and arsenic. Alpha-BHC, delta-BHC, dieldrin, 4,4-DDE, and 4,4-DDT are present in on-site monitoring wells, according to tests conducted by EPA in 1987-88. An estimated 35,000 people obtain drinking water from public wells within 3 miles of the site. The closest is approximately 3,500 feet from the site.. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response. Compensation, and Liability Act (CERCLA) as amended in 1986 CARSON RIVER MERCURY SITE Lyon/Churchill Counties, Nevada The Carson River Mercury Site (CRMS) consists of: (1) sediments in an approximately 50-mile stretch of the Carson River in Lyon and Churchill Counties, beginning between Carson City and Dayton, Nevada, and extending downstream through the lahontan Reservoir to Stillwater National Wildlife Refuge; and (2) tailing piles associated with the river. In the late 1800s, ore mined from the Constock lode near Virginia City was transported to any of 75 mills, where it was crushed and mixed with mercury to amalgamate the gold and silver. The availability of water power made 12 mills along the Carson River in the Brunswick Canyon area become dominant. Mercury-contaminated tailings piles which resulted from the mills have been found 5 miles up Brunswick Canyon, 3 miles up Six Mile Canyon, and within the Carson Plain. Areas near the Comstock lode where extensive mining occurred, such as in Gold Canyon, may also be major potential sources of tailings. Rain transports mercury from the tailing piles to the Carson River, where the Nevada Division of Environmental Protection (NDEP) has documented extensive mercury contamination. An estimated 7,500 tons of mercury were lost in the milling process during the 30-year peak of the Comstock Lode, of which only about 0.5% was later recovered. Much of the remaining mercury was incorporated in the mill tailings. Elevated levels of mercury attributed to the piles were detected in the river from above the Dayton area through the Lahontan Reservoir to the cutoff of the Stillwater Slough, as well as in Six Mile Canyon Creek. Because CRMS extends over such a large area, it potentially affects several sources of ground water, among them the Dayton Valley Aquifer. Ground water in the aquifer is as shallow as 10 feet near the river, and soils are permeable sands and gravel. These conditions facilitate movement of contaminants into ground water. An estimated 1,400 people obtain drinking water, from wells within 3 miles of the site, the nearest within 2,000 feet. Approximately 1,200 acres of food and forage crops are irrigated by the Carson River between Dayton and the Lahontan Reservoir. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended in 1986 SEALAND RESTORATION, INC. Lisbon, New York The Sealand Restoration, Inc., Site occupies approximately 200 acres south of Pray Road in Lisbon, St. Lawrence County, New York. The surrounding area, consisting largely of farmland and wetlands, is sparsely populated. In the late 1970s, the company, also known as Sealand Industrial Services, Inc., disposed of waste oils and oil spill debris under a permit issued by the New York State Department of Environmental Conservation (NYSDEC). In addition, wastes were accepted from numerous industrial plants in central and northern New York State. Wastes were stored or disposed in three on-site facilities: a drum storage area, a disposal pit, and a landfarming operation. The site stopped operating in 1981. In 1980, the New York State Department of Health (NYSDH) found low levels of cadmium in residential wells near the site. Under a Consent Order Agreement in 1981, Sealand Restoration agreed to clean up the site; however, the firm was subsequently cited for nonconpliance. The site has been referred to the State Attorney General. According to NYSDEC, St. Lawrence County received a $100,000 Local Assistance Grant in 1984 from the New York State Legislature to perform limited cleanup at the site. The county removed 133 drums left on the surface, along with 60 full or partially full buried drums, 42 empty buried drums, and 150 cubic yards of contaminated soil. These wastes were transported to a hazardous waste facility regulated under Subtitle C of the Resource Conservation and Recovery Act. Acetone, trichloroethane, toluene, benzene, and trichloroethylene were present in on-site monitoring wells downgradient of the landfill, according to tests conducted in 1986-88 by a consultant to NYSDEC. An estimated 1,100 people obtain drinking water from private wells within 3 miles of the site, one of which is on the site. The on-site well has been taken out of service. Trichloroethane and tetrachloroethylene were detected in surface water downhill from the site in tests conducted by the State (1980) and EPA (1985). A fresh water wetland lies within and adjacent to the site. The area is used for recreational activities. NYSDEC has conducted a study to determine the type and extent of contamination at the site. The study determined that surface soils contain low levels of PCBs, and that contaminants are migrating downward in soils beneath where the drums had been stacked. The shallow aquifer is contaminated downgradient of the disposal pit. Possible interconnection with a deeper aquifer must be assessed.

(GUSHING PLANT) Gushing, Oklahoma Kerr-McGee Corp.'s Gushing Plant covers 116 acres in Gushing, in a rural area of Payne County, Oklahoma. Since 1915, numerous oil and pipeline companies have occupied various portions of the site. In 1956, Kerr-McGee acquired a refinery on the site and operated it until 1972. During 1963-65, Kerr-McGee conducted various uranium processing operations in a plant on the site for the Atomic Energy Comnission (AEG). From early 1965 until February 1966, Kerr-McGee produced thorium metal from thorium nitrate provided by AEG. After operations ceased in 1966, the plant was demolished. In 1972, soil and wash water containing thorium were placed in an on-site surface impoundment known as Pit 4. A number of other impoundments (Pits 1, 2, 3, and 5) contain acid sludges and oily wastes from the oil operations; the pits were filled in prior to 1956. In 1986, EPA detected uranium, radium, chromium, nickel, zinc, and arsenic in on-site monitoring wells. An estimated 7,800 people obtain drinking water from public and private wells within 3 miles of the site. A private well is 1,000 feet from the site. U.S. Environmental Protection Agency/Rsmedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended in 1986 UNION PACIFIC RAILROAD CO. TIE-TREATING PLANT The Dalles, Oregon The Union Pacific Railroad Co. Tie-Treating Plant covers 83 acres in a mixed conmercial and residential area just south of the Columbia River in the City of The Dalles, Wasco County, Oregon. Union Pacific owned the wood treatment facility from 1926 to late 1987, when equipment and structures were purchased by Kerr-McGee Chemical Corp.; however, Union Pacific retained ownership of the land and responsibility for all pre-1987 contamination of facility soil and ground water. The plant primarily treated railroad ties for Union Pacific, but also treated wood for other conmercial users across the United States. From 1959 to-November 1987, J. H. Baxter Co. operated the plant for Union Pacific. The facility treated wood with ammoniacal copper arsenate, creosote, creosote/fuel oil mixture, and pentachlorophenol. Spills of treatment solutions on-site and waste water ponds no longer in use are thought to be the main source of contamination of soil and ground water. Improvements in the waste water treatment system allow the site to operate as a zero discharge facility. In 1984, Union Pacific began a comprehensive investigation of soil and ground water at the site. Creosote components, pentachlorophenol, fuel oil, ammonia, and arsenic are the major contaminants found in soil and ground water at the site. Contamination by arsenic and volatile organic compounds is greatest in the shallow and intermediate aquifers beneath the site. Organic contaminants, such as phenanthrene and naphthalene, have been detected in the two deep confined aquifers beneath the site. Ground water is used by over 11,000 people within 3 miles of the site. The City of The Dalles has increased its monitoring of the municipal supply wells. In May 1989, Union Pacific signed a Consent Order with the Oregon Department of Environmental Quality and agreed to undertake a remedial investigation/feasibility study to determine the type and extent of contamination at the site and identify alternatives for remedial action. The work is scheduled to be completed by mid-1991. U.S. Environmental Protection Agency/Remedial Response Program ------- National Priorities List Superfund hazardous waste site listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended in 1986 DUBLIN TCE SITE Dublin Borough, Pennsylvania The Dublin TCE Site covers approximately 4.5 acres in Dublin Borough, Bucks County, Pennsylvania. In June 1986, the Bucks County Health Department discovered trichloroethylene (TCE) in 23 tap water samples. The water supplies of approximately 170 homes, apartments, and businesses in Dublin have been impacted. The highest TCE concentrations (up to 10,000 parts per billion) were found in a well on property that has been occupied by several industrial operations over the past 50 years. EPA considers this property, located at 120 Mill Street in Dublin Borough, to be the likely source of the contaminants. According to EPA's report on its search for parties potentially responsible for wastes associated with the site, the companies that operated on-site include Dublin Hosiery Mills, Inc.; Home Window Co. of Pennsylvania, Inc.; Kollsman Motor Corp.; and Dudley Sports Division of Athlone Industries, Inc. John H. Thompson acquired the property in January 1986 and is using the main building to restore antique race cars. Laboratory Testing/ Inc., has leased part of the property since May 1986, but no evidence has been found to date to suggest that either this company or Mr. Thompson used or disposed of TCE on the property. The sole source of drinking water in the area is the Brunswick and Lockatong Formations, which are nydraulically connected, permitting water to move between them. An estimated 10,100 people obtain drinking water from public and private wells within 3 miles of the site. On June 29, 1987, Mr. Thompson entered into a Consent Order with EPA under CERCLA Section 106(a). Under the order, Mr. Thompson is providing water treatment systems or bottled water to persons with contaminated wells and is periodically sampling wells in the area. He has also been cooperating with requests from the Pennsylvania Department of Environmental Resources to study soil and ground water at the site.

Compensation, and Liability Act (CERCLA) as amended in 1986 OHIO RIVER PARK Neville Island, Pennsylvania The 32-acre Ohio River Park Site is on the western end of Neville Island in Allegheny County, Pennsylvania. It is almost conpletely surrounded by the Ohio River. The site was owned by Pittsburgh Coke & Iron Co. [later named Pittsburgh Coke & Chemical Co. (PC&C)] from the 1920s until 1970, when the property was transferred to a wholly owned subsidiary, Neville Land Co. In 1976, the property was donated to the county. According to EPA, from the 1930s until the mid-1950s, the site served as a landfill for municipal wastes from Neville Township. From 1952 until 1965, trenches were dug on-site to dispose PC&C's wastes such as coking sludges (which often contain benzene and toluene), cement production wastes, and pesticides. Other industrial wastes such as plant demolition materials and slag were also disposed on-site. In 1978, Allegheny County began developing the site as a park but stopped construction after industrial waste was found. In 1979, an Allegheny County consultant reported that on-site ground water and soil contained contaminants such as benzene, toluene, 2,4-dichlorophenoxy acetic acid (2,4-D), 2,4,6-trichlorophenol, and 2,4-dichlorophenol. The consultant concluded that a public health threat existed at the site. The land was then returned to Neville Land Co. Routine monitoring by the county's consultant consistently detects benzene and toluene in ground water. Neville Land hired a consultant to further evaluate the site. The work has included installation of 27 multilevel wells, extensive sampling, excavation of test pits, analysis of aerial photographs, and toxicological and hydrogeological evaluations. Limited remedial actions were taken, including the removal of a container of almost pure 2,4-D and the surrounding soil, stabilization of a section of shoreline where sulfur-containing waste was exposed, installation of a fence, and posting of warning signs. An estimated 40,000 people obtain drinking water from public and private wells within 3 miles of the site. Seven municipal wells are 600 to 1,200 feet from the site. An outfall from a storm sewer system which drains a small portion of the northeastern quadrant of the site is contaminated with 2,4-dichlorophenol, 2,4,6-trichlorophenol, 2,4-0, and 2,4,5-T, according to tests Allegheny County's consultant conducted in 1979 and 1981. This outfall discharges to the Ohio River. Sewickley Water Works draws water from the river 1.7 miles downstream from the contaminated outfall. The intake provides drinking water to an estimated 8,000 people.

Compensation, and Liability Act (CERCLA) as amended in 1986 f PARA-CHEM SOUTHERN, INC. Sinpsonville, South Carolina Para-Chan Southern, Inc., has manufactured organic solvents and adhesives on a 100-acre site near Sinpsonville, Greenville County, South Carolina, since 1965. The area is rural and sparsely populated. During 1975-1979, 800 to 1,600 drums of organic and inorganic wastes were buried in unlined trenches in three parts of the site, according to information the company provided to EPA as required by CERCLA Section 103(c). Waste water front the plant was disposed of in two unlined lagoons until November 1984, when the South Carolina Department of Health and Environmental Control (SCDHEC) issued Para-Chem a permit under the National Pollutant Discharge Elimination System (NPDES). In October 1985, SCDHEC found manganese and several organic chemicals, including chloroform, carbon tetrachloride, and 1,1,1-trichloroethane, in on- site wells; carbon tetrachloride and 1,1,2-trichloroethane in off-site ground water and surface water; and arsenic, barium, manganese, nickel, and zinc in sediments in on-site surface water. 1,1-Dichloroethylene, 1,1-dichloroethane, 1,1,1-trichloroethane, 2-butanone, and tetrahydrofuran were found in on-site monitoring wells in tests conducted in July 1987 by a Para-Chem consultant. An estimated 1,500 people obtain drinking water from private wells within 3 miles of the site, the nearest within 1 mile. SCDHEC placed the company under a joint waste water/hazardous waste Consent Order in February 1985, and in January 1986 fined the company for violating its NPDES permit. The order also addressed the buried drums and a spill of 3,500 gallons of ethylacrylate in January 1985. Since 1986, the company has been fined twice for failure to meet its NPDES permit. i Under the Consent Order, Para-Chem excavated soil from the drum burial areas and filled in the two lagoons. The soil was moved to a hazardous waste facility regulated under Subtitle C of the Resource Conservation and Recovery Act. The action was completed in 1987. During the action, ground water contamination consistent with earlier analyses was discovered.

The base is bordered by open land on three sides and residential/cxmnercial areas on the fourth. Established in 1942, Ellsworth is now the base for the 44th Strategic Missile Wing of the Strategic Air Command (SAC). Base operations generally support the SAC mission and include runways, airfield operations, fire protection training, industrial and maintenance shops, a base hospital, grounds maintenance, a photo lab, and housing facilities. These operations generate a variety of chlorinated solvents, solvent-contaminated waste oils, pesticides, and other ha«*TTV*i« wastes that were deposited at various locations on the base. Ellsworth Air Force Base is participating in the Installation Restoration Program (IRP), established in 1978. Under this program, the Department of Defense seeks to identify, investigate, and clean up contamination from hazardous materials. EPA has evaluated five contaminated areas—four unlined landfills and the Fire Protection Training Area burn pit. As part of IRP, 16 contaminated areas have been identified; the Air Force is investigating 8 — the 5 EPA evaluated, plus an additional landfill, hydrant fuel lines, and the old auto hobby shop. On-site shallow monitoring wells dcwngradient from the landfills and burn pit are contaminated with 1,1-dichloroethane, 1,2-dichloroethylene, triohloroethylene, arsenic, and chromium, according to tests conducted in 1987-88 by the Army Corps of Engineers. An estimated 1,600 people obtain drinking water from wells within 3 miles of the site, the nearest less than 1 mile dcwngradient of the burn pit and two of the landfills.

DISPOSAL PIT Sioux Falls, South Dakota The Williams Pipe Line Co. Disposal Pit is in the northeast corner of the coirpany's 12th Street terminal in Sioux Falls, Minnehaha County, South Dakota. The terminal is bordered on the south by 12th Street (State Highway 42), on the west by Valley View Road and a residential development, on the north by the Chicago & Northwestern Railroad tracks, and on the east by Marion Road. The site is 2 miles west of the Big Sioux River and Skunk River. The unlined pit measures 9 feet by 9 feet and is about 7 feet deep. For a number of years prior to 1986, a variety of wastes generated by the terminal were dumped into the pit. Until the 1970s, wastes were burned periodically. The pit is now dry and covered with a plastic sheet. Tests conducted in 1986-87 by EPA show that sediment in the pit contains barium, beryllium, chromium, copper, iron, lead, zinc, benzene, toluene, xylene, polynuclear aromatic hydrocarbons, and pesticides. Ground water near the pit is contaminated with 4,4'-ODD, 4,4'-DDT, gamma- chlordane, beta-BHC, and lead, according to EPA tests conducted in 1989. An estimated 100,000 people in the Sioux Falls area obtain drinking water from two sets of public wells within 3 miles of the site. One well is about 1.25 miles to the southeast.

Compensation, and Liability Act (CERCLA) as amended in 1986 BETTER BRITE PLATING CO. CHROME AND ZINC SHOPS DePere, Wisconsin The Better Brite Plating Co. Chrome and Zinc Shops occupy 2 acres and are approximately 2,000 feet from each other in a primarily residential area of DePere, Brown County, Wisconsin. Metal plating operations conducted at the shops since the early 1960s have contaminated soil and ground water as a result of spills and leaking storage facilities. After the company filed for bankruptcy in October 1985, operations ceased at the chrome shop. In April 1986, EPA used CEHCLA emergency funds to remove contaminated soil, chromic acid, cyanide sludge, and flammable liquids from the chrome shop. All materials were transported to a hazardous waste facility regulated under Subtitle C of the Resource Conservation and Recovery Act. In May-June 1987, the Wisconsin Department of Natural Resources (WDNR) used the Wisconsin Environmental Repair Fund to install seven monitoring wells, three of them extending 20 feet into bedrock. Soil and ground water were analyzed. The results indicated chromium contamination into both the shallow aquifer and the upper bedrock aquifer. An estimated 46,000 people obtain drinking water from municipal wells within 3 miles of the site. DePere municipal well 12 is about 500 feet downgradient of the zinc shop. During 1986-88, the State issued orders to stop operations at the zinc shop. The site was abandoned in July 1989. In March 1988, WDNR received a complaint that yellow water was running from the chrome shop into the city storm sewer. WDNR found chromium in the run-off and in soil at a neighboring residence. The City of DePere is periodically pumping a trench on the chrome shop property and discharging the waters to the DePere Wastewater Treatment Plant. In October 1988, WDNR was notified that the plating building at the shop had been sold and was to be removed. To prevent exposure of grossly contaminated soil under the building, WDNR razed the building, partially fenced the site, installed a clay cap, covered it with top soil, and seeded the cover. In June 1988, EPA emergency funds were used to design a pretreatment system for water being discharged from the site to the DePere Wastewater Treatment Plant. U S.
