United States Office of April 2003 Environmental Protection Solid Waste and Agency Emergency Response Descriptions of 14 Proposed Sites and Seven Final Sites Added to the National Priorities List in April 2003 Office of Emergency and Remedial Response Intermittent Bulletin State & Site Identification Center ( 5204G) Internet Volume 6, Number 1 This document consists of descriptions of the 14 proposed sites and seven final sites added to the National Priorities List ( NPL) in April 2003. The size of the site is generally indicated, based on information available at the time the site was scored using the Hazard Ranking System ( HRS). The size may change as additional information is gathered on the sources and extent of contamination. Sites are grouped according to proposed or final status, and are arranged alphabetically by site name within those groups.

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 the 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 for conducting a remedial response at a hazardous waste site and 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 Oil and Hazardous Substances Pollution 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 24months 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 per site ( plus any costs to operate and maintain the action), 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.

Eighteen acres of the site ( along the western boundary) are located within the City of Baltimore and the remainder of the site is located near the town of Rosedale in Baltimore County, Maryland. The five sources that make up the 68th Street Dump site were used as landfills from the 1950s through the 1970s. Historical inspection reports, accounts from former waste haulers and employees, and EPA investigations of potential generators provide evidence that industrial wastes were disposed of at the 68th Street Dump site. Hazardous substances detected in samples collected from the five sources that comprise the site include: volatile organic compounds, polyaromatic hydrocarbons ( PAHs), polychlorinated biphenyls ( PCBs), pesticides, and metals.

Three removal actions have occurred at the site. In 1982, up to 23 drums of hazardous waste ( due to elevated lead and cadmium concentrations) were removed from Source 5. In 1984, 10 drums were removed from Source 4; one contained paint sludge whereas the remainder were empty and badly deteriorated. In 1985, a fire at Source 3 initiated an EPA emergency response action that concluded with the removal of 40 drums partially filled with solvents.

Prior to dumping activities, the entire area of the 68th Street Dump site was covered with wetland vegetation. Historical aerial photographs taken of the area document the filling of these wetlands and adjacent stream channels, documenting observed releases by direct observation. Surface water bodies that flow through the site include Herring Run, Moore s Run, Redhouse Run, and unnamed tributaries to Herring Run. The Back River and Chesapeake Bay are located along the 15 mile surface water pathway target distance limit ( TDL) for the site. Targets within the 15 mile TDL include the Herring Run, Back River, and Chesapeake Bay fisheries and over 23 miles of wetland frontage. Analytical results of sediment samples collected from the Herring Run fishery downstream of the site document contamination with PAHs, lead, and zinc. Analytical results of samples collected from wetlands remaining at the 68th Street Dump site document elevated concentrations of PAHs, PCBs, and metals.

A separate HRS score has been calculated for each of the five sources evaluated in this HRS documentation record. The documentation supporting each of these individual scores is provided in Appendices C through G of the documentation record.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 AMCO CHEMICAL Oakland, California The AMCO Chemical site ( AMCO) is part of a 0.83 acre property at 1414 Third Street in a mixed residential and light industrial area of Oakland, California. The property is bordered on the north by a vacant lot, on the west by residences, on the east by Nelson Mandela Parkway, and on the south by Third Street. A recently constructed elevated portion of the Interstate 880 ( I 880) freeway is located immediately across Third Street from the property. The property ( at 1401 Third Street) was historically occupied by Bobo s Junkyard.

From the 1960s to 1989, the AMCO site was occupied by AMCO Chemical Company. AMCO operated a chemical distribution facility that included a warehouse, railroad spur, above ground tanks, underground tanks, and drums used to transfer and store raw materials. In July 1988, the Oakland Fire Department observed   leaking/ rotting drums  on the property. A subsequent emergency response investigation by Alameda County and the U. S. Coast Guard revealed greater than 100 full and empty 5 and 55 gallon weathered drums in an open area behind AMCO Chemical s main building. Stenciled labels on the drums indicated that the contents included acetone; 1,1,1 trichloroethane ( 1,1,1 TCA); methyl ethyl ketone; and dry cleaning solvent. From 1989 to November 1998, DC Metals operated a scrap metal yard on the site. Cable Moore, Inc., currently uses the site for cable storage. Structures remaining on site include an office building, warehouse, and two small storage buildings.

In June 1995, a construction crew noted odors at the intersection of Third Street and Nelson Mandela Parkway, while excavating a trench needed to relocate an underground electrical line in preparation for a freeway project. Subsequent subsurface investigation by California Department of Transportation ( Caltrans), DC Metals, and EPA revealed the presence of volatile organic compounds ( VOCs) including vinyl chloride in soil, soil gas, and shallow ground water at the AMCO site, beneath Third Street, and at the 1401 Third Street property ( former Bobo s Junkyard).

On December 5, 1996, the EPA Emergency Response Office initiated a removal action at the AMCO site that involved the construction of a ground water and soil vapor extraction ( SVE) treatment system. The EPA treatment system collection trench was excavated from December 5 through December 20, 1996. By December 23, 1996, the trench had been lined with a silt curtain, filled with gravel, and covered with a tarp. Cement was poured to permanently cover the trench on January 8, 1997. The treatment system operated from January 1997 through July 1998 and extracted approximately 7,000 pounds of VOCs, approximately 40 pounds of which were vinyl chloride. Operation of the system ceased in July 1998, due to community concern over the potential for a release of dioxins from the thermal oxidation unit. On December 5 and 14, 1996, during construction of the treatment system collection trench, the EPA On Scene Coordinator observed shimmering vapors emanating from the open trench. SUMMA   canister sampling indicated the presence of vinyl chloride; methylene chloride; 1,1,1 trichloroethane ( TCA); and trichloroethene ( TCE) in the immediate area of the trench. In addition, one SUMMA canister sample collected from in front of a residence adjacent to the site contained TCE.

The EPA conducted several sampling events on and adjacent to the AMCO site between 1997 and 2000. VOCs continued to be detected in soil, soil gas, and ground water on site. In September 1999, SUMMA canister samples were collected from the crawl spaces of three residences located adjacent to the site. Vinyl chloride was detected in the three crawl spaces at 0.02 to 0.045 parts per billion by volume ( ppbv).

There are 626 people living within a quarter of a mile of the source. There are also approximately three workers on site.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 ARMCO INC., HAMILTON PLANT Hamilton, Ohio The Armco, Inc. Hamilton Plant ( Armco) site is associated with a 120 acre inactive industrial facility located in Hamilton, Ohio. The facility property is bordered by the Great Miami River to the east and south, by the Baltimore and Ohio Railroad to the north and west, and is divided into a northern portion and a southern portion by Augspurger Road. The southern parcel consists of 92 fenced acres and was used for manufacturing operations, including a coke production facility and blast furnaces. The northern parcel is unfenced and consists of approximately 27 acres. The northern parcel was formerly a rail yard and temporary storage area for scrubber sludge waste piles and also contains a 4.5 acre landfill. The facility operated as a steel mill, producing both coke and molten iron, under various ownership since the 1900s. Armco purchased the facility in 1937 from the Hamilton Coke and Iron Company, and AK Steel subsequently acquired the facility in 1994. Armco manufactured both coke and iron until 1982 when coke production ceased. Armco continued to produce iron until 1991, and the facility was then used intermittently until it was completely closed in 1994.

The coke operation covered approximately 50 acres on the southern portion of the property. Byproducts of the coke operation included coal tar, naphthalene, coke oven gas, crude light oil, and ammonium sulfate. The waste streams from the operation were passed through an exhauster and flushed into a decanting tank. The decanted coal tar sludge was periodically drained from the bottom of the tank and disposed of in a landfill on the northern portion of the property from the early 1960s until the landfill was closed in 1980.

The blast furnace operation covered approximately 6 acres on the southern portion of the property. Wastewater generated in the blast furnace operation was discharged to two settling ponds located adjacent to the blast furnaces, where particulates were allowed to settle out. Excess water from these ponds was originally discharged to the Great Miami River under a National Pollutant Discharge Elimination System ( NPDES) permit. The contact wastewater, from the blast furnace off gas and wet scrubbers, contained pollutants such as ammonia, cyanide, phenol, and lead and zinc bearing flue dust (  scrubber sludge ). The settled scrubber sludge was periodically dredged from the two settling ponds and stored in piles in the northern portion of the property.

EPA conducted a Screening Site Inspection ( SSI) at Armco in September 1988. Sampling results from this SSI indicated the presence of SVOCs, such as phenanthrene, fluoranthene, pyrene, and chrysene in the facility landfill. Sampling results also indicated the presence of SVOCs, such as benzo( a) pyrene, and metals, such as lead and chromium, in the southern settling pond. EPA collected analytical data during an Expanded Site Inspection ( ESI) conducted at Armco in July 1993. These data confirmed the presence of SVOCs and metals in the two settling ponds and indicated the presence of PCBs in both ponds. These data also revealed soil contaminated with SVOCs, PCBs, and significant levels of metals in the area where the scrubber sludge piles were formerly stored.

Armco used four NPDES permitted outfalls that discharge directly to the Great Miami River. These outfalls discharged both process wastewater from the facility and storm water runoff. Two storm water outfalls that drained the facility property were sampled during a July 8, 1991 storm event. The samples documented the direct discharge of hazardous substances, such as di n octylphthalate, titanium, barium, and zinc, to the Great Miami River. Analytical data collected during the July 1993 ESI documented significant concentrations of SVOCs, including 4 methyl phenol ( o cresol), fluoranthene, benzo( k) fluoranthene, and benzo( g, h, i) perylene, and metals, including chromium and zinc, in the sediments of the Great Miami River. The Great Miami River is a recreational fishery for species such as bluegill and smallmouth bass in the vicinity of the site. Habitat for the Indiana bat, a federally designated endangered species, is within the target distance limit for the site.

The Armco site is located less than one half mile from the City of Hamilton s North Plant wellfield, which serves approximately 35,763 people. The Village of New Miami Wellfield is located within one mile of the site and serves a population of approximately 3,045. A total population of 60,605 is served by wells within four miles of sources at the site. Although ground water contamination has not been detected, the aquifer occurs at 40 feet below ground surface in the vicinity of the site.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 CAPTAIN JACK MILL Ward, Colorado The Captain Jack Mill ( CJM) site is located in a narrow valley, roughly 1.5 miles south of Ward, and 14 miles west of Boulder, Colorado. Mining began in the area in the early 1890s. The mines and mills in the Ward area primarily produced gold and silver from low grade ores. Camp Francis was started in the early 1890s as a mining town operated by the Big 5 Mines Company, which employed approximately 100 men. The Big 5 managed such mines as the Adit, Ni Wot, Columbia, and the Big Dew Drop, and all of the combined ores from these mines came down to Camp Francis by way of the Adit Tunnel. Milling of the ore took place either in the Dew Drop Mill or the Big 5 Mill just south of town. Several hundred feet downstream of the mills were three other mines, the nearest of which is known as the Captain Jack, later called the Black Jack. These mills were still standing as late as 1927, and never processed large quantities of ore.

The Big 5 was reopened in the 1940s but it is unclear if they intended to produce ore from the mines or rework the tailings piles by the mills on the creek. Captain Jack, Ltd., acquired possession of the mill works area in March 1974, and received a Colorado Mined Land Reclamation Division ( CMLRD) permit allowing for a captive mill ( i. e., no imported ore) operation using a flotation process in May 1981. Since that time, the CJM site has been investigated for several state and federal health and environmental violations under several different owners.

At the time of the most recent investigation, the CJM site could be divided into three parts; the upper mine tunnel ( the Big 5), the Captain Jack mill works area, and the lower portal ( the Black Jack Mine). The Big 5 consists of the mine tunnel, a large tailings pile and a settling pond, all of which are approximately 500 feet upstream from the Captain Jack mill area. An acid mine water discharge of several gallons per minute ( gpm) runs across the tailings pile, down the access road and into the settling pond. At times in the past, this discharge water has flowed across the access road and directly into Left Hand Creek. The more recent Captain Jack mill works area includes two ponds ( the unlined lagoon for settling tailings from the mill and the lagoon that is lined with a plastic membrane), a small abandoned residence, an ore hopper and associated conveyor belts, mill buildings, storage and processing tanks, mixing tanks, and miscellaneous debris and equipment. The lower portal consists of the Black Jack adit and adit shed contents.

Left Hand Creek is a documented fishery. In 1997, surface water and sediment samples collected in Left Hand Creek indicated the presence of lead, zinc, arsenic, barium, cadmium, and mercury. All are associated with the ores both mined and milled at the site. Elevated levels of hazardous substances have also been found in sediment samples collected from palustrine emergent shrub wetlands located along Left Hand Creek. Left Hand Creek is a recreational fishery and is used for sport fishing, canoeing, picnicking, and rafting. In addition, significant concentrations of arsenic was detected in residential soil samples.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 CONROE CREOSOTING COMPANY Conroe, Texas The Conroe Creosoting Company facility occupies 147 acres in Conroe, Texas. Conroe Creosoting Company was a wood treating facility that operated from 1946 until March 14, 1997. The facility treated lumber, railroad cross ties, poles, and fence posts. Three wood preserving processes, pentachlorophenol ( PCP) process, creosote process, and copper chromated arsenate ( CCA) process, were used at the facility. The facility was closed down by the Montgomery County Tax Assessor/ Collector due to delinquent taxes and the county sold the company s assets at an auction. The land and waste management and process units remained property of the owners. The site is being proposed to the NPL because elevated levels of pentachlorophenol ( PCP), dioxins, polycyclic aromatic hydrocarbons ( PAHs), and metals have been found in on site soils, surface water, waste drums, and surface impoundments, threatening nearby residents, wetlands, and rivers. The property has been flooded three times since 1994, sending contaminated flood waters into nearby residential homes and yards.

Surface impoundments containing creosote waste currently drain off site via drainage canals. Runoff from the site flows overland both to the east to Little Caney Creek and to the west to Stewarts Creek. In June 2001, a waste inventory listed several cylinders and tanks containing copper chromated arsenate solution, creosote sludge, pentachlorophenol solutions and solids, and tank bottoms. The total quantity of hazardous waste in the tanks and containers other than drums was estimated to be over 100,000 gallons. Approximately sixty two ( 62) overpacked drums in poor condition were stored in an on site shed.

Texas Commission on Environmental Quality ( TCEQ, formerly Texas Natural Resource Conservation Commission) conducted several compliance investigations at the company during the 1980s and 1990s. Violations documented at the site resulted in the issuance of Agreed Orders in 1994 and 1999. Sampling by Conroe Creosoting Company in September of 1996 indicated elevated levels of creosote compounds, including arsenic, chromium, and copper in soil and shallow groundwater. In March 2001, TCEQ observed contents leaking out of containers. During a November 2001 expanded site investigation, TCEQ uncovered a hazardous waste dumping area onsite, and detected creosote related hazardous substances in soils and sediments. Soil samples collected on site revealed concentrations of dioxins 100 times the EPA s action level of 1 ppb. Soil and sediment samples from creeks downstream of the site indicate concentrations of arsenic as high as 14.2 ppm, copper as high as 10.0 ppm, chromium as high as 17.7 ppm, and several semi volatile organic compounds, including fluoranthene as high as 4,600 ppb, pyrene as high as 1,000 ppb, and phenanthrene as high as 1,500 ppb.

EPA conducted a removal assessment of the facility in January 2002. Tanks, cylinders, impoundments, drums, and soils were sampled and analyzed for volatile organic compounds, semi volatile organic compounds, and metals. In addition, five soil samples were analyzed for dioxins and furans. Over 500,000 gallons of liquid, sludge, and contaminated water were identified during the assessment, and approximately 65,000 cubic yards of soils were found to exceed the EPA Region 6 Screening Guidance for either arsenic, chromium, pentachlorophenol, total creosote compounds, or dioxin and furans. An ongoing EPA removal action is addressing on site process areas, contaminated soil and sediment.

Two residential neighborhoods are located immediately downstream on Stewart s Creek, within the 100 year flood plain. These homes have been subject to at least three severe flood events ( water in their homes) since 1994. Any large rain event will cause Stewart s Creek to flood, sending contaminated water into the yards of residents who border the creek. Surface water from the facility eventually enters the West Fork San Jacinto River, which is a small to moderate stream and is a fishery. A wetland is located along the banks of Stewarts Creek. Analytical results of samples collected from the wetland area document contamination attributable to the facility.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 JONES ROAD GROUND WATER PLUME Harris County, Texas The Jones Road Ground Water Plume site is located approximately one half mile north of the intersection of Jones Road and FM 1960 in a mixed residential, urban/ light industry area outside the city limits of northwest Houston, Harris County, Texas. The site is being proposed to the NPL based upon the presence of hazardous substances, including cis 1,2 dichloroethene ( DCE), tetrachloroethene ( PCE), and tricholorethene ( TCE), in drinking water wells. PCE has been detected in drinking water wells above EPA s Maximum Contaminant Level ( MCL) of 5.0 µ g/ L.

During a routine sampling of public wells by the TCEQ Houston Region Office in December 2000, PCE, DCE, and chloromethane were detected in a public well supplying drinking water to approximately 18 employees, 90 children in childcare, and 150 to 200 students at a gymnasium. Subsequent samples collected on January 25 and May 2, 2001 confirmed the presence of PCE, DCE, and chloromethane in the public drinking water supply well.

During the Site Inspection in March and April of 2002, the Texas Commission on Environmental Quality ( TCEQ) collected samples from 43 wells in Harris County and found concentrations of PCE at or above the MCL in 8 wells. Concentrations of PCE in ground water samples were as high as 128 µ g/ L. As a result, filtration systems have been placed on those 8 wells.

The source of the PCE, TCE, and DCE contamination is unidentified, though previous investigations have suggested several potential source areas near the affected drinking water wells. There are several businesses within the area that use chlorinated solvents. In June 2001, a Phase I Environmental Assessment was conducted at Bell Dry Cleaners and leakage was discovered from a dry cleaning machine at Bell Dry Cleaners into the storm drains. This facility is over 1,000 feet north of the public supply well at the gymnasium. PCE and vinyl chloride was found in ground water and soil samples collected from the Bell Dry Cleaners facility during the Environmental Assessment. On May 1, 2002, TCEQ initiated an Emergency Order which directed the owner of Bell Dry Cleaners and the owner of the property to, among other actions: maintain the current filtration systems; sample all wells within a half mile of the facility and add filtration systems to any new wells with contamination; investigate and report on the nature and extent of the contamination; and conduct any necessary further investigation. In May 2002, Bell volunteered to stop using PCE. On August 21, 2002, an Order was issued affirming modifications to the May 1, 2002 Emergency Order. This ordered the facility and property owners to: ( 1) continue cessation of all use of PCE at that location, ( 2) grant access for remediation, and ( 3) add a deed restriction to the shopping center property that prohibits use of PCE. However, the owner of the facility and the property owner were determined to be incapable of proceeding with remediation due to lack of funds.

Based on samples collected from March to December 2002, 228 wells have been sampled in the area including and surrounding the Jones Road Ground Water Plume site. Of these wells, 23 wells have had detections of PCE at or above the Environmental Protection Agency s Maximum Contaminant Level ( MCL) of 5 parts per billion ( ppb). Filtration systems have been placed on the 23 wells with levels of PCE at or above the MCL. Eighteen wells have had detections of PCE below the MCL.

Public and private drinking water wells serving residents, workers, and students have been found to be contaminated with chlorinated solvents above MCLs and other EPA health based drinking water standards.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 MADISON COUNTY MINES Fredericktown, Missouri The Madison County Mines site is located in the Old Lead Belt area of southeastern Missouri in the vicinity of Fredericktown, Madison County, Missouri, approximately 80 miles south of St. Louis. The site is being proposed to the NPL because of the presence of metal contamination, including lead, in residential soil and within nearby surface water bodies the Little St. Francis River and its tributaries. Lead was detected in residential yards at levels as high as 10,000 milligrams per kilogram ( mg/ kg) or more than 70 times that of background levels. The primary sources of metal contamination are large uncontained tailings and chat piles associated with local historical operations that mined for lead, copper, cobalt, nickel, iron, zinc, silver, and pyrite. Some of these mining operations date back to the 1840s.

Metal contaminants from tailings piles migrated through various routes to residential soil and nearby surface water bodies. In 1977, a tailings pond dam broke and released accumulated tailings into tributaries of the Little St. Francis River. In addition, several tailings piles have grown so large that they have spilled over directly into the Little St. Francis River and its tributaries. For years, residents of Fredericktown have used tailings from piles as fill for yards, gardens, roads, and driveways. This practice is likely responsible for much of the residential soil contamination observed at the site. Other modes of contaminant deposition in residential yards includes flooding of contaminated water bodies and emissions from nearby smelters.

A number of studies and investigations have been undertaken at the site since 1983. Collectively, these have revealed metals contamination in local ground water, surface water and sediments associated with Little St. Francis River and its tributaries, residential soil, and air. Groundwater samples collected from onsite monitoring wells and piezometers revealed arsenic, copper, lead, and nickel concentrations above EPA's Maximum Contaminant Levels ( MCL) and greater than three times background concentrations. Surface water sampling revealed concentrations of arsenic, cadmium, copper, chromium, lead, mercury, nickel, and zinc above Ambient Water Quality Criteria ( AWQC). Specifically, lead was detected in surface water up to 12 micrograms per liter ( µ g/ L) and sediment up to 11,000 mg/ kg. Soil sampling in residential yards revealed lead at concentrations as high as 10,000 mg/ kg. Air sampling revealed filter concentrations of arsenic, cobalt, copper, lead, and nickel at greater than three times background concentrations.

Metals contamination from the site has impacted the Little St. Francis River, which is an active fishery with documented wetlands and habitats used by state endangered species. In addition, a number of residential properties have also been impacted. EPA conducted soil screening at 215 residential properties in Fredericktown, Missouri, and identified 92 of these properties with soil lead concentrations above 400 mg/ kg. EPA observed the presence of tailings in driveways, sidewalks, or elsewhere on 42 of these 92 residential properties and approximately 200 other residential properties in Fredericktown.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 NEWTON COUNTY MINE TAILINGS Newton County, Missouri The Newton County Mine Tailings site is located in southwest Missouri in the Tri State Mining District. The site is being proposed to the NPL because of the presence of lead and cadmium contamination in residential drinking water wells significantly above the current health based drinking water limits. Based on current sampling information, the contaminated ground water encompasses approximately 160 square miles. In 1999, EPA provided bottled water to county residents as an immediate, temporary response to the known health threat associated with the consumption of lead and cadmium contaminated water. Currently, 350 residential properties in Newton County receive bottled water from EPA and have no alternative safe drinking water supply.

From approximately 1850 to 1950, lead, cadmium, and zinc mining were major industries in Newton County and the land is marked by numerous open mine shafts, tailings piles, and underground mine workings. In addition, the extensive mining activity has resulted in unique underground channels and faults with exposed lead, cadmium, and zinc ores. The mines were located below the water table and during periods of operations were kept dry by pumping ground water from the shafts. Following abandonment of the mines, pumping ceased, the water table returned to its natural levels, and the ground water came in contact with abandoned underground mines and exposed ore. Lead, cadmium, and zinc ground water contamination resulted when the oxygenated water leached metals from the exposed ores in the abandoned mines. Further contamination resulted from lead, cadmium, and zinc leaching from surface waste piles into the ground water through naturally occurring faults and the numerous constructed mine shafts throughout the county.

Following reports of elevated blood lead levels in children in surrounding counties with similar mining histories, EPA conducted limited sampling around the city of Granby in 1995, followed by more extensive ground water and soil sampling throughout Newton County in 1998 and 2000. The upper aquifer is the sole source of drinking water for private residential wells throughout Newton County. Based on the 2000 sampling data, at least 200 residential wells are contaminated with lead or cadmium above health based benchmarks of 15 ppm of lead and 5 ppm of cadmium. In addition, the 1998 soil sampling indicated surface soil lead contamination as high as 33,500 milligrams per kilogram ( mg/ kg) in the city of Granby.

In addition to the ground water contamination, several hundred properties have elevated levels of lead and cadmium in the surface soil. A removal action conducted in 1999 2000 included excavation of contaminated soils from a number of properties. The criteria for removal included properties with soil samples ( collected outside the roof drip line) containing lead concentrations equal to or greater than 400 mg/ kg. Currently, removals have occurred at 221 properties. No further soil remedial action at these properties is anticipated based on information currently available. Soil removal at additional residential properties is ongoing.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 PETERS CARTRIDGE FACTORY Kings Mills, Ohio The Peters Cartridge Factory formerly operated on a 10 acre parcel of land at 1415 Grandin Road, on the south side of the Little Miami River in Warren County, Ohio. The facility is bordered by a U. S. military reservation ( ordnance plant) to the southwest, the Little Miami Scenic Trail and the Little Miami River to the north and west, and rural areas to the east and south.

The Peters Cartridge Factory operated as a manufacturer of semi smokeless cartridge ammunition, including shotgun shells and rifle and pistol cartridges. The company expanded north across Grandin Road during World War I due to increased demand for ammunition from the European Powers and the United States. After the war, the frame buildings erected to keep up with the war demands were demolished, and the company was consolidated back to its original buildings at the present site location. Remington Arms purchased Peters Cartridge Factory in 1934, and continued to manufacture rifle and shotgun ammunition until near the end of World War II. In 1944, the facility was closed as part of a consolidation by Remington. The Columbia Records division of RCA occupied the facility from 1944 to 1948, mixing plastic materials and manufacturing phonograph record disks. Seagrams Distillers used the facility as a bonded warehouse during the 1950s. A small cabinet company used a portion of the facility around the 1970s. In 1979, the facility was purchased by Landmark Renaissance Corporation and is currently known as the Kings Mills Technical Center. LensCrafters leased the property from January 1987 to December 1991. LensCrafters used chemicals such as Freon 113, surfactants, phosphoric acid, n hexane, paints, tints, and dyes in the manufacture of eyeglass lenses and frames. Several other companies owned or leased the present facility, but they did not use chemicals in their operations.

In 1987 as part of an environmental assessment for the Kings Mills Technical Center, lead contamination was discovered at the site. On site soils were sampled at depths of 1, 4, 8, and 12 feet, and lead was found at concentrations reaching 33,500 parts per million ( ppm) at a depth of 4 feet. Fill materials including boiler ash and slag were found buried in layers from 7 to 12 feet thick on the property. Monitoring wells were installed on site in December 1987 and were sampled and analyzed for lead and total organic content. Lead was detected in well W 3 at 0.52 milligrams per liter ( mg/ l), well above the maximum contaminant level of 0.015 mg/ l. In 1993, the facility was paved to prevent direct contact with lead contaminated soil.

An Expanded Site Inspection was conducted on May 4, 5, and 11th , 1999 by the Ohio EPA. Soil, sediment, ground water, and fish tissue samples were collected. Observed releases to ground water and to the Little Miami River were documented. The Little Miami River, which is threatened by contamination from the site, is a fishery and a State and National Scenic River. Several municipal drinking water wells are within four miles of the site.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 RAM LEATHER CARE Charlotte, North Carolina The Ram Leather Care site is a former dry cleaning facility located in Charlotte, North Carolina. The facility, which operated from 1977 to 1993, is situated in a rural area in eastern Mecklenburg County, about 1,500 feet west of the Cabarrus County line. A sample taken in 1991 from the facility s drinking water well, which served 8 to 10 employees at the time, showed tetrachloroethylene ( PCE) at 4,690 micrograms per liter ( ug/ l). As a result, use of the well was discontinued and a new well was installed. Later sampling has shown that this well also was contaminated. In addition, chlorinated solvents have been detected in residential wells near the facility. Ram Leather Care employees and nearby residents with contaminated wells were advised not to consume the ground water.

Illegal open burning of PCE filters was discovered at the Ram Leather Care facility in April 1991. Subsequently, 49 unmarked drums were discovered on a pad on the west side of the building. Drum bungs were found open, and the drums were standing in liquid. An illegal boiler blowoff discharge also was observed. Soil and runoff samples collected during this time showed the presence of chlorinated solvents and phthalates. In June 1991, the drums were manifested off site to a reclamation site. The boiler blowoff discharge was discontinued.

In 1991, Mecklenburg County issued the Ram Leather Care facility a Notice of Violation for improper disposal of a potentially hazardous waste. Also in 1991, the North Carolina Division of Solid Waste Management and the North Carolina Division of Environmental Management issued Notices of Violation to the facility. In 1992, a Compliance Order with an Administrative Penalty of $ 126,998 was issued to the facility. Ram Leather Care declared bankruptcy in 1993. In 1995, the North Carolina Superfund Section conducted sampling for a combined Preliminary Assessment/ Site Inspection. The North Carolina Superfund Section discovered that a new well had been installed at the nearest residence and consumption of ground water had resumed. This new residential well contained PCE at 204 ug/ l. The North Carolina Superfund Section requested a removal action, and EPA subsequently installed filtration systems on three contaminated private wells. State funds paid for change out of the filters until 2000, when the funding expired.

In 1999, EPA initiated surface and subsurface soil and ground water sampling as part of the Expanded Site Inspection/ Remedial Investigation ( ESI/ RI). A subsequent Groundwater Investigation Report was completed in August 2001. The results of the ESI/ RI sampling event documented an estimated 11,875 square foot area of surface soil containing PCE, DDD, gamma chlordane, and bis ( 2 ethylhexyl) phthalate. During the 1999 sampling event, a 10 foot deep borehole was discovered in the area of contaminated soil. Contaminants in soil at the bottom of this borehole included PCE, gamma chlordane, and bis ( 2 ethylhexyl) phthalate. The level of PCE ( 78 milligrams per kilogram or mg/ kg) in soil in the borehole was the highest of any soil sample collected on the site. Subsurface soil samples collected during the ESI/ RI showed contaminated soil extending down to the top of the bedrock at 45 feet below land surface. A number of samples collected at varying depths served to document an estimated 19,686 cubic yards of contaminated soil containing PCE, trichloroethene, cis 1,2 dichloroethene, and vinyl chloride at the Ram Leather Care site.

Contaminants detected in soils at the Ram Leather Care facility include chlorinated solvents, petroleum related compounds, pesticides, and bis ( 2 ethylhexyl) phthalate. Chlorinated solvents have been detected in drinking water wells at concentrations exceeding health based benchmarks and in monitoring wells. Ground water is the only source of drinking water within at least 1 mile of the facility. It is estimated that 522 people within 1 mile of the facility and an additional 7,977 people within 4 miles of the facility rely on ground water for drinking. Although sampling has not shown a release to the surface water pathway, wetlands and fisheries are present downgradient of the site. The facility is currently used for a weekend flea market, but the owner has been instructed not to use water from the facility s well for any purposes.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 ROLLING KNOLLS LANDFILL Chatham Township, New Jersey The Rolling Knolls Landfill facility is an approximately 200 acre, unlined, former municipal landfill located at 35 Britten Road in the Green Village section of Chatham Township, Morris County, New Jersey. The facility is bound by the Great Swamp National Wildlife Refuge to the east, south, and west; Loantaka Brook and private property to the west; and private residential properties to the north and northwest. The Rolling Knolls Landfill overlaps the Refuge on its eastern and southern sides.

The Rolling Knolls facility operated as a municipal landfill from the early 1930s through December 1968. During that time, Rolling Knolls Landfill received municipal solid waste, as well as construction and demolition debris from surrounding municipalities. Chatham Township Board of Health ( CTBH) records indicate that the types of wastes deposited at Rolling Knolls included tree stumps, scrap metal, tires, household refuse, residential septage wastes, and industrial waste. In order to comply with health code regulations adopted in 1959, operational procedures at the facility included the application of pesticides to control weeds, insects, and rodents, as well as the application of oil on facility roadways to control dust. In addition, health code regulation also required the application of minimal daily cover ( 6 inches) to all exposed surfaces including the face of the fill. Chatham Township records indicate that semi liquid swamp muck was picked up from the edge of the landfill using a dragline and applied as the daily cover.

One source has been identified for the HRS evaluation of the site: The Rolling Knolls Landfill. Analytical results of soil samples collected from the site by the U. S. Environmental Protection Agency ( EPA) during the May 1999 Expanded Site Inspection ( ESI), indicate elevated levels ( i. e., above regulatory levels) of metals, phthalates, and polychlorinated biphenyls ( PCBs).

The facility is bound by the Great Swamp National Wildlife Refuge to the east, south, and west. The Refuge is a designated national wildlife refuge and is habitat known to be used by state and federally designated or proposed endangered or threatened species. There is a documented observed release of mercury and PCBs to a surface water/ sediment sampling location in a portion of the landfill that is situated within the boundaries of the Refuge.

Drainage from the landfill flows directly to Black Brook and to Great Brook via Loantaka Brook. All are perennial streams that ultimately discharge to the Passaic River. The Passaic River supports fish that are suitable for human consumption and is fished.

The waste source samples collected from the landfill by EPA in May 1999 document contamination. The southern and eastern portions of the Rolling Knolls Landfill lie within the boundaries of the Refuge, which is a designated national wildlife refuge and wilderness area, and is habitat known to be used by state and federally designated or proposed endangered or threatened species. Therefore, waste source samples collected from the landfill by EPA in May 1999 document actual contamination of a terrestrial sensitive environment. Private, residential properties border the facility on the west, north, and northwest. Waste source samples collected by EPA in May 1999 document potential exposure of nearby residents. The Rolling Knolls facility is accessible and is not covered by a permanent, or otherwise maintained essentially impenetrable material.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 STANDARD CHLORINE CHEMICAL COMPANY, INC. Kearny, New Jersey The Standard Chlorine Chemical Company, Inc. ( Standard Chlorine), site is located in an industrial area along the tidally influenced Hackensack River in Kearny Township, New Jersey. Chemical manufacturing and/ or processing occurred at the 25 acre facility from the early 1900s to the 1990s. Operations included the production and refinement of naphthalene, the storage and packaging of 1,4 dichlorobenzene moth preventatives and deodorizers, the production of dye carriers, and the processing of liquid petroleum naphthalene for the manufacture of moth balls and flakes, as well as several other manufacturing activities.

In December 2001, New Jersey Department of Environmental Protection ( NJDEP) requested that EPA evaluate the Standard Chlorine site for listing on the National Priorities List due to the complex environmental issues present at the site and the inability of the responsible parties to address the issues. The NJDEP indicated that Standard Chlorine had not completed Remedial Investigation activities and was non compliant with the terms of an 1989 Administrative Consent Order ( ACO). The NJDEP has terminated their ACO with Standard Chlorine.

Several potential source areas exist at the Standard Chlorine site. The primary areas of concern include contaminated soils throughout the site and two lagoons located on the eastern portion of the facility property. Another concern is an area of PCB contaminated soils and concrete in the vicinity of a former transformer located adjacent to Building 2 on the western portion of the property. All of these areas appear to ultimately drain into the Hackensack River via three probable points of entry: a drainage pipe along the northern property boundary, a drainage ditch that runs along the southern property boundary, and overland runoff that flows directly from the facility property to the river. Free phase product in the soils and groundwater also appears to discharge directly to surface water bodies. Tanks and drums containing ( or at one time contained) various site related hazardous substances, including dioxin contaminated asbestos, also are present at the facility. In addition, contaminated fill material from non site related chromium ore processing activities is present on the site property, as well as on other properties in the Hackensack Meadowlands.

The predominant hazardous substances associated with the lagoons and surrounding contaminated soils include: benzene, dichlorobenzenes, chlorobenzene, trichlorobenzenes, naphthalene, and dioxin ( TCDD). In addition, PCB 1260 was detected at 9300 milligrams per kilogram ( mg/ kg) in concrete chips taken from the vicinity of the former transformer, and at lesser concentrations ( 0.12 to 0.29 mg/ kg) in soil samples collected directly beneath the concrete pavement.

Data from sampling events conducted between 1992 and 2002 indicate that a release of site related hazardous substances has occurred to the Hackensack River and adjacent wetlands. Dioxins, Dichlorobenzenes, 1,2,4 trichlorobenzene, naphthalene, benzene, and chlorobenzene, as well as several other semivolatile and volatile organic compounds, have been detected at varying levels in these samples. During the 2002 EPA sampling event, dioxin ( 2,3,7,8 TCDD) was detected at 96.1 nanograms per kilogram ( ng/ kg) in a sediment sample taken in the Hackensack River. Surface water samples taken from the outfall at the point of discharge to the Hackensack show concentrations of naphthalene at 45 micrograms per kilogram ( µ g/ kg) and 1,2,4 trichlorobenzene at 12 µ g/ kg. A seep was also observed entering the Hackensack River from the sediment southeast of the outfall where the southern drainage ditch confluences with the Hackensack River. The seep was black in color with observed sediment. Chemical analysis of the seep indicates the presence of 1,4 dichlorobenzene at 2 µ g/ kg.

Warnings pertaining to the consumption of some fish ( particularly crab) and a health advisory have been issued for the Hackensack River due to PCB and dioxin contamination, originating in part from the Standard Chlorine site. Reportedly, however, fishing still occurs along the river. The site lies in the Hackensack Meadowlands which has been identified by the US Fish and Wildlife Service as a Significant Habitat Complex of the New York Bight Watershed at the request of the US EPA s New York  New Jersey Harbor Estuary Program, and may be a habitat for some state or Federal designated endangered and/ or threatened species. Releases of site related hazardous substances to ground water also have been documented since at least the early 1980s.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 TROY MILLS LANDFILL Troy, New Hampshire The Troy Mills Landfill ( a. k. a. Rockwood Brook Landfill), which is owned and operated by Troy Mills, Inc., is located off of a dirt road on a mostly wooded property consisting of 270 acres. The landfill covers 10 to 13 acres approximately 1.5 miles south of the town of Troy, New Hampshire and been used since 1967 as an industrial disposal area by the owner, a local fabric manufacturer. Contaminated leachate has been documented seeping from the landfill into a stressed wetland area, which is hydraulically connected to Rockwood Brook. Rockwood Brook flows north toward the town of Troy. Sand Dam Pond, a recreational pond used for swimming and fishing is located on Rockwood Brook approximately 1 mile downstream of the landfill. The site is being proposed to the NPL because elevated levels of metals, volatile organic compounds ( VOCs), and semi volatile organic compounds ( SVOCs) are leaking from an estimated 11,000 buried drums and uncontainerized waste at the landfill, endangering the downstream fisheries, recreation areas, and wetlands.

Part of the Troy Mills landfill is still active, receiving fabric wastes, cleaning wastes containing Varsol and methyl ethyl ketone, building materials, damaged fiberboard drums, and plant equipment parts and tools. The smaller portion of the landfill, now closed, received surplus mixes and tank residues of vinyl resins, top coating products, plasticizers, pigments, industrial organic solvents and chemicals, and numerous steel drums between 1968 and 1978.

In July and August 1980, the New Hampshire Water Supply and Pollution Control Division collected samples from the landfill leachate, indicating the probable presence of inorganic constituents above background concentrations. Additional studies conducted by Troy Mills, Inc., in the 1980s identified crushed drums and drummed liquid and sludge wastes throughout the landfill, with approximately 11,000 drums estimated to be buried in the landfill. Sampling of the wastes identified metals, SVOCs, and VOCs, including xylenes up to 19,000 ppb, bis ( 2 ethylhexyl) phthalate up to 110,000 ppb, benzyl butyl phthalate up to 13,000, di n octyl phthalate up to 6,200 ppb, and cadmium, chromium, and zinc at varying concentrations. Elevated levels of iron and manganese were detected in ground water and leachate, as well as 1,1,1 trichloroethane, ethylbenzene, toluene, trichloroethylene, 1,2 dichloroethane, 1,1 dichloroethane, benzene, methylene chloride, and tetrachloroethylene detected in ground water. These studies also noted visibly stressed vegetation at leachate outbreaks downgradient of the drum disposal area.

In 1986, the New Hampshire Department of Environmental Services ( NH DES) and Troy Mills, Inc., entered into a consent order that required remedial work at the landfill. In 1992, Troy Mills, Inc., completed a feasibility study detailing a proposed remedy that included capping the inactive disposal area, installing additional monitoring wells, and, if necessary, implementing a ground water recovery and treatment system.

EPA conducted an Expanded Site Inspection ( ESI), including a wetland delineation, in October and December 2001. Surface water and sediment samples were collected from the leachate seep, wetlands, and Rockwood Brook. The results document an observed release to a wetland area west of the toe of the landfill. The leachate was found to be contaminated and directly discharging to the wetland. The primary contaminants of concern in the ESI were manganese, lead, cadmium, copper, chromium, zinc, bis ( 2 ethylhexyl) phthalate, di noctylphthalate cis 1,2 DCE, xylenes ( total), ethylbenzene, and toluene. These contaminants threaten downstream fisheries, a designated recreation area, and wetlands.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 WHITE SWAN CLEANERS/ SUN CLEANERS AREA GROUND WATER CONTAMINATION Wall Township, New Jersey The White Swan Cleaners/ Sun Cleaners Area Ground Water Contamination site consists of overlapping contaminated ground water plumes from sources located on two properties in a commercial/ residential area of Wall Township, Monmouth County, New Jersey. The sources are located at the former White Swan Laundry and Cleaners ( a. k. a., Summit Bank, Fleet Bank), 1322 Sea Girt Avenue; and the former Sun Cleaners, 2213 Route 35 ( a. k. a., 201 Manasquan Circle). The former Sun property is located approximately 0.3 mile southwest of the former White Swan property.

In August 1997, a resident of Magnolia Avenue in Wall Township informed the Monmouth County Health Department ( MCHD) that ground water samples collected in 1990 from three private irrigation wells had exhibited concentrations of tetrachloroethylene ( PCE) up to 1,546 parts per billion ( ppb). MCHD resampled the three irrigation wells, and sampled four additional irrigation wells. The analytical results indicated the presence of PCE in ground water at levels up to 595 ppb. The New Jersey Department of Environmental Protection ( NJDEP) determined that three Sea Girt Municipal wells were at risk of contamination and sampled them for volatile organic compounds ( VOC) on a monthly basis beginning in April 1999. No contamination was detected until September 1999, when PCE was detected in one of the wells at a concentration of 0.54 micrograms per liter ( ug/ L  equivalent to ppb).

In 1995 1996, Phase I and Phase II Assessments were conducted at Sun Cleaners. Areas of concern identified at the facility during these assessments included a steel 30 gallon drum and a steel 55 gallon drum, both located north of the Sun Cleaners building, and a discharge pipe that was connected to a PCE separator. Analytical results of soil samples collected during the Phase II Assessment indicated the presence of PCE at a concentration of 51 parts per million ( ppm) in the vicinity of the 30 gallon drum and 8.2 ppm in the vicinity of the discharge pipe. A subsequent Environmental Site Investigation included the collection of subsurface soil and ground water samples from borings advanced in the vicinity of the Sun Cleaners building. Analytical results from this investigation indicated the presence of PCE at concentrations up to 7,400 milligrams per kilogram ( mg/ kg) in subsurface soil and up to 200,000 ug/ L in ground water. The highest PCE concentrations ( in both soil and ground water) were detected near the 55 gallon drum.

In 1999, NJDEP initiated a ground water investigation in the area in an effort to identify responsible parties for the PCE ground water contamination. During this investigation, ground water samples were collected throughout the area. As a result of this investigation, White Swan Laundry and Cleaners and Sun Cleaners were identified as possible sources of the ground water contamination. Site Inspections ( SI) were conducted by NJDEP at each of these facilities. Soil and ground water samples confirmed that a release of PCE had occurred at each of the sites. Based on the SI findings, White Swan Laundry and Cleaners and Sun Cleaners were identified as contributing sources of the area wide ground water contamination.

An observed release of PCE to ground water is documented by the chemical analyses of ground water samples collected from direct push method borings during the NJDEP SIs conducted at the White Swan Cleaners and Sun Cleaners properties. An observed release of PCE to ground water is also documented by the chemical analyses ofground water samples collected from monitoring wells located on the White Swan Laundry and Cleaners facility. In addition, an observed release of PCE to ground water is documented by the chemical analyses of aqueous samples collected in 1999 and 2000 from a municipal well ( i. e., Well # 6) operated by the Borough of Sea Girt. On each occasion, Level II contamination was documented for this well, which served an approximate population of 1,170 people at the time of the initial release. Drinking water within the site s 4 mile radius is obtained from public supply wells and private wells screened in the Kirkwood Cohansey Aquifer System, which is the aquifer of concern. In addition, several wellhead protection areas exist within the 4 mile target distance limit. Other areas of environmental concern include indoor air quality of nearby homes and commercial facilities, and contaminated ground water discharges to nearby surface water bodies.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 DAVENPORT AND FLAGSTAFF SMELTERS Sandy City, Utah Conditions at Proposal ( December 1, 2000): The Davenport and Flagstaff Smelter site is located east of the Town of Sandy City, Salt Lake County, Utah at the mouth of Little Cottonwood Canyon. A number of smelters operated in Little Cottonwood Canyon during the 1870s. Three of these smelters were located at the mouth of the canyon, the Davenport Smelter south of Little Cottonwood Creek, the Flagstaff Smelter on the north bank of Little Cottonwood Creek, and the McKay Smelter located immediately adjacent to the former Davenport Smelter site. The small town of Granite was built near the smelters and during its heyday ( 1872 1874) consisted of about 50 buildings serving the workmen at the smelters and the teamsters who hauled the ore from the mines. When the smelters closed, the town was abandoned.

The Davenport Smelter was a lead and silver smelter located on the south side of Little Cottonwood Creek just west of the mouth of Little Cottonwood Canyon. The smelter was located on the property purchased by the Davenport Mining Company from S. J. Despain on March 7, 1873. Ores smelted at the site were mined primarily from the Davenport and Matilda Mines located in Little Cottonwood Canyon and were hauled by wagon from the mines to the Davenport Smelter. The ores contained more than sixty to seventy ounces of silver per ton and were by volume between 12 and 18 percent lead. The smelter operated from 1872 until 1875. Early smelting activities in the Salt Lake Valley were reported to be conducted in a "... sadly careless and ignorant manner" and "... that in many cases half the lead is lost to the slag or up the chimney." L. E. Despain, the son of S. J. Despain, wrote in a letter dated January 12, 1948, that "... the smoke stacks were not built very high, and the flue dust fell on the vegetation ( sic) poisoned ( sic) all the horses, cattle, sheep and honey bees."

There are no records available that indicate that any material was removed from the Davenport Smelter site after 1875. It is reported that remains of the Davenport Smelter foundation have been identified at one of the residences included within the area of contamination. Large amounts of cobble sized slag have been reported in the back yards of the residents. Current land use at the site includes a residential neighborhood and school.

The Davenport Smelter site was listed in the CERCLA Information System ( CERCLIS) in April 1992 after site discovery during a study of historic smelters in the Salt Lake Valley conducted by the state of Utah. Soil samples were collected from the area of the Davenport and McKay smelters and analyzed for lead and arsenic in June of 1992 and a site assessment was conducted in July 1992. A Preliminary Assessment was conducted in August 1992. Sampling for a Site Inspection was conducted in June of 1994 and the Analytical Results Report was approved in April 1996. An Engineering Evaluation/ Cost Analysis ( EE/ CA) was conducted by the Utah Department of Environmental Quality ( UDEQ), Division of Environmental Response and Remediation ( DERR) for the Flagstaff and Davenport sites. Sampling for this EE/ CA in part involved the collection of 946 soil samples from the area collected from October through December of 1998. Analytical data from samples collected for the EE/ CA were used to prepare a map showing the area of contaminated soil.

The area of contaminated soils occurs in a residential area west of the mouth of Little Cottonwood Canyon, south of Little Cottonwood Creek and north of Little Cottonwood Road in an area that was known as the Beaver Pond Springs. The contaminated properties are located on Little Cottonwood Lane, Quail Ridge Road, Old Ranch Place, and Little Cottonwood Place. Soil samples from residential properties were collected by the UDEQ during October, November, and December of 1998 and reveal that 15 properties have documented levels of arsenic in the residential soil that are greater than three times the regional background. Twenty two properties have documented levels of lead in the residential soil that are greater than three times the regional background.

In September of 2002, contaminated soil was excavated from the residential property at 9767 South Little Cotton Wood Place, Sandy, Utah; owned by Robert and Linda Grow. The property owners worked with and obtained approval for the removal from the Utah Department of Environmental Quality and the US Environmental Protection Agency.

Status ( April 2003): EPA is considering various alternatives for this site.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 GULFCO MARINE MAINTENANCE Freeport, Texas Conditions at Proposal ( September 5, 2002): The Gulfco Marine Maintenance ( Gulfco), facility encompasses 40 acres in Freeport, Brazoria County, Texas. The facility historically was used as a barge cleaning and servicing facility. The Gulfco site encompasses three buried/ backfilled surface impoundments that received contaminated wash water from the barge cleaning operations, areas of contaminated soil, and releases to surface water and ground water. The site is being proposed to the NPL based on evidence that hazardous substances, including semivolatile organic compounds, lead, zinc, and pesticides, have migrated from the facility to the Intracoastal Waterway, pose a threat to nearby drinking water supplies and downstream sensitive environments, and have impacted fisheries downstream of the facility.

Gulfco operated as a barge cleaning and waste disposal facility from 1971 through 1979. Operations at the facility involved the cleaning, servicing, and repair of various chemical barges. Chemical barges were drained and pumped to remove product heels, which then were stored in tanks and sold as product. Each barge was washed with water or a detergent solution. Generated wash waters were stored either in surface impoundments, a floating barge, or on site storage tanks. The barges were allowed to air dry and certified as safe prior to initiating repair work such as welding and sandblasting.

The surface impoundments received wash water from the cleaning of barges and other transport vessels that carried organic substances including alcohols, ketones, and crude oil. Waste wash water generated during the cleaning of chemical barges and other vessels was hard piped to the surface impoundments for evaporation and separation. The maximum inventory of waste at any given time was 5.5 million gallons. The surface impoundments were certified closed in August 1982, following removal of the liquids and sludges, solidification of the remaining sludge with soil, and capping with three feet of clay cover and a hard wearing surface. Some sludge reportedly remained in one of the surface impoundments at the time of closure.

Underlying the Gulfco site is the Chicot/ Evangeline aquifer system. This aquifer system is a major source of municipal and smaller public water supply systems in the Freeport area. The largest public water supply system within 4 miles of the site is that of the city of Freeport, which supplies approximately 11,300 people. The city of Freeport uses 100 percent of the surface water supplied by the Brazos Water Authority. The city also has seven ground water wells, two of which are maintained for emergency use only, and have not been used for drinking water for several years. The remaining wells are scheduled to be abandoned.

The site lies within the 100 year coastal floodplain along the north bank of the Intracoastal Waterway between Oyster Creek to the east and the Old Brazos River Channel and the Dow Barge Canal to the west. The southern part of the Gulfco site drains to the south where it enters the Intracoastal Waterway, which is a fishery. The surface water migration pathway extends in all directions within contiguous surface water bodies since these surface water bodies are tidally influenced. Surface water flows eastward into the Drum Bay, Christmas Bay, Bastrop Bay, and Galveston Bay. Galveston Bay is the seventh largest estuary in the United States and is designated as a National Estuary as part of the National Estuaries Program. In addition, Christmas Bay is designated as the Christmas Bay Coastal Preserve of the Texas Coastal Preserve Program, and harbors eight endangered or threatened species including the Bald Eagle, Brown Pelican, Peregrine Falcon, Whooping Crane, Piping Plover, Reddish Egret, White faced Ibis, and Green Sea Turtle. The 12,199 acre Brazoria National Wildlife Refuge is located to the south of Bastrop Bayou and contains the habitats of three state threatened species, including the Wood Stork, White tailed Hawk, and the Swallow tailed Kite. A wetland area is located approximately 500 feet south of the site across the Intracoastal Waterway. This area is classified as intertidal estuarine, emergent, persistent, and regularly flooded. Twenty miles of wetland frontage lie within 15 stream miles of the site.

Status ( April 2003): EPA is considering various alternatives for the site.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 OMAHA LEAD Omaha, Nebraska Conditions at Proposal ( February 26, 2002): The Omaha Lead site includes surface soils present at residential properties, child care facilities, schools, and other residential type properties in the city of Omaha, Douglas County, Nebraska that have been contaminated as a result of air emissions from lead smelting operations. The total area of the Omaha Lead site is approximately 8,840 acres. The site is being proposed to the NPL because of the presence of lead contamination in soil at residential properties, child care facilities, schools, and other residential type properties.

The Asarco facility conducted lead refining operations from the early 1870s until 1996 . The Asarco facility is located on approximately 23 acres on the west bank of the Missouri River in downtown Omaha. During the operational period, lead and other heavy metals were emitted into the atmosphere through smoke stacks. The pollutants were transported downwind in various directions and deposited on the ground surface due to the combined process of turbulent diffusion and gravitational settling. In addition, Gould, Inc., operated as a lead battery recycling plant and was considered a secondary lead smelter in the area. The Gould, Inc., plant closed in 1982. Several other businesses in the Omaha area utilized lead in their manufacturing process. Subsequently in 1998, the Omaha City Council solicited assistance from the U. S. Environmental Protection Agency ( EPA) in addressing problems with lead contamination in the Omaha area. The EPA initiated the process to investigate the lead contamination in the area under the authority of the Comprehensive Environmental Response, Compensation, and Liability Act.

An ongoing removal action included excavation of lead contaminated soils from a number of properties. The criteria for removal included child care facilities and residences where blood lead concentrations in children were equal to or greater than 10 micrograms per deciliter ( µ g/ dl) and where soil samples ( collected outside the roof drip line) contained lead concentrations equal to or greater than 400 milligrams per kilogram ( mg/ kg). Currently, removals have occurred at over 290 properties. No further remedial action at these 290 properties is anticipated based on information currently available.

EPA prepared a Preliminary Assessment/ Site Inspection Report in 2001. This report summarized numerous investigations that have been conducted at the Omaha Lead site. Results of these investigations indicate that lead contamination is present at elevated concentrations up to 2.5 miles from the former Asarco facility.

Approximately 65,615 residents are located within the identified area of soil contamination. There are twenty Omaha Public Schools within this area including fifteen elementary schools, one middle school, two high schools, and two special study centers. The total enrollment at the twenty schools is 11,725 students. There are approximately 240 child care facilities within a 3 mile radius of the center of the site. The total number of children attending these facilities is unknown. Several parks and golf courses are present within the identified area of soil contamination. These parks are accessible to the public and provide recreational opportunities to the public. In addition, approximately 135 acres of wetlands are located within the 4 mile radius of the site.

Status ( April 2003): To date, removals have occurred at over 290 properties. These properties do not include the residents, schools, and daycare facilities described above.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 PESTICIDE WAREHOUSE III Manati, Puerto Rico Conditions at Proposal ( September 5, 2002): The Pesticide Warehouse III ( PWIII) site is an active facility located at Road No. 670, kilometer ( km) 3.7, in a rural/ residential area of Manati, Puerto Rico. The site is approximately 2 acres in size and consists of a main warehouse, a smaller warehouse, and a small shed which contains an on site well. The PWIII site is bounded to the south by Road No. 670, to the west and north by fields, and to the east by a church and a retirement home. The Puerto Rico Land Authority ( PRLA) owned and operated the site from 1954 to 1996. Site operations during this period included the preparation of pesticides/ insecticides, herbicides, and fertilizers. The site is currently privately owned and operated.

In 1996 1997, EPA conducted a Site Inspection ( SI) investigation which consisted of an on site reconnaissance and a subsequent sampling site inspection. During the reconnaissance, the following were noted to be stored in bags within the main warehouse: magnesium sulfate, Ochoa fertilizer, sulfate of potash, zinc sulfate, ferrous sulfate, urea, MoCap 10G, Karmex DF, Baylethon, Hyvar X, Nemacor 3, and Solobar. Spilled materials were noted throughout the warehouse. In addition, stained soils were noted throughout the site. Surface drainage was observed to be toward the west, where it entered a drainage ditch. This ditch extended along the western and northern boundaries of the site, where it terminated in a leach pit located north of the on site buildings. This pit was observed to be unlined and appeared to be a natural sinkhole.

Based on the potential for pesticide contamination on site and the potential impact to off site receptors, EPA conducted an SI sampling event which included the collection of 15 surface soil samples ( depth: 0 to 6 inches) at locations both on and off the PWIII site. Diazinon, Malathion, Diuron, and Toxaphene were detected in on site surface soil samples at concentrations significantly above background. These contaminants were also detected at concentrations significantly above background in samples collected from the drainage ditch and associated leach pit. These contaminants were either observed on site or were listed in site Material Safety Data Sheets ( MSDS). Other pesticides detected in on site soils at concentrations significantly above background included alpha BHC, Heptachlor, Aldrin, Endosulfan I, Dieldrin, Endrin, alpha Chlordane, and gamma Chlordane. Several pesticides detected on the PWIII site exceeded EPA Soil Screening Levels ( SSLs). Zinc was also detected at concentrations significantly above background in both on site soils and the retirement home located adjacent to the PWIII site. The contamination is related to improper handling of pesticides/ insecticides, herbicides, and fertilizers.

Two sources have been identified for the Hazard Ranking System ( HRS) evaluation of the site: contaminated soil and the drainage ditch and associated leach pit. There are other areas of environmental concern, such as a pit observed at the bottom of a former truck scale located south of the main warehouse entrance, and a cistern located below the ruined northeast portion of the main warehouse building, and suspected asbestos containing materials located on some of the piping runs within the small warehouse.

Ground water threatened by the PWIII site serves an approximate population of 118,970 people. These people obtain potable water from wells screened in the North Coast Limestone Aquifer System ( i. e., the aquifer of concern), which has karst aquifers beneath the site. The nearest potable well is the Coto Sur No. 5, which is located approximately 700 feet west of the PWIII site. This well serves an approximate population of 1,260 people. In addition, analytical data from the SI indicates that there is documented soil contamination at the nearby retirement home, which has a building within 15 feet from the eastern border of the PWIII property. The population of the retirement home is estimated to be 50 people. There are currently 20 workers at the PWIII site.

Status ( April 2003): EPA is considering various alternatives for this site.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 UNITED METALS, INC. Marianna, Florida Conditions at Proposal ( September 5, 2002): The United Metals, Inc., site is located in Marianna, Jackson County, Florida, approximately 2.5 miles south of Interstate 10 and approximately 1,000 feet east of State Road 71. The site, which is now abandoned, was used primarily as a lead acid and nickel cadmium battery reclamation facility. The site is being proposed to the NPL because a release of lead, chromium, and other metals has been documented in facility soils, in a nearby wetland, and in a habitat used by a Federally threatened species. The release also poses a threat to a downstream recreational fishery and additional wetland areas.

From 1979 until 1991, United Metals, Inc., processed and recycled used batteries within a 24 acre fenced area at its Marianna facility. In 1981, the facility processed as many as 10,000 to 12,000 batteries per week, resulting in 2,500 gallons of acidic wastes per day. Until sometime in the early 1980s, treated and possibly untreated wastewater from the recycling process flowed into a settling basin, then into concrete basins, and finally through a ditch to an unlined holding pond. A second holding pond was constructed to provide additional capacity, but allegedly was never used. The wastewater system eventually was modified so that the wastewater was stored in tanks, eliminating the discharge to the holding pond. The holding ponds subsequently were abandoned, dredged, and backfilled. Dredged sediments from the holding ponds and from contaminated drainage ditches currently are stockpiled in the recycling building on site.

During the 1980s, the Florida Department of Environmental Regulation ( FDER) conducted several inspections at the facility. In August 1981, FDER and United Metals, Inc., entered into a Consent Order that required numerous actions to be undertaken by United Metals, including payment of a fine, submittal of a detailed plan evaluating the wastewater system, identification of environmental problems, completion of a limited ground water assessment, and proposal of corrective actions. In July 1986, EPA conducted a RCRA program inspection. EPA noted that RCRA violations persisted, including improper closure of the holding ponds following sediment removal, improper storage of hazardous wastes, inadequate ground water monitoring, and operating without appropriate permits for hazardous waste storage and treatment. As a result of these violations, EPA issued an Amended Complaint and Compliance Order.

United Metals, Inc., discontinued recycling operations and sold the facility to Anrich Industries, Inc. Anrich subsequently renovated the facility and began battery cracking operations in May 1991. On May 22, 1991, the Florida Department of Environmental Protection ( FDEP) conducted a Hazardous Waste Inspection of the facility. FDEP noted several RCRA violations and, in July 1991, ordered that all operations cease. In June 1993, a Site Inspection was conducted that included the collection of 15 soil samples and the installation of five monitoring wells. Soil samples collected from the facility production area and drainage ditches were found to be contaminated with lead. In 1994, an Expanded Site Investigation confirmed the presence of lead at significant levels in facility soils and in the drainage ditch that flows into the wetland area.

In March 1995, the EPA Removal Assessment Team conducted a site visit to determine the site s eligibility for a removal action. EPA collected six surface soils samples, four waste samples from 55 gallon drums and three storage tanks, and two water samples to identify the nature and extent of contamination and to identify the immediate threat to the public and environment. Lead was detected in soils, a flammable liquid was discovered in drums, and 800 gallons of sulfuric acid was found in an on site storage tank. As a result of these findings, EPA initiated limited removal activities in January 1996, and returned in March 1996 to complete the removal.

The main area of concern at the United Metals, Inc., facility is contaminated soil where the battery recycling activities were performed, as well as contaminated soil along the drainage route to the wetland area located west of the facility. Metals contamination has been documented in the wetland, which also serves as a habitat for the Flatwoods Salamander, a Federally threatened species.

Status ( April 2003): EPA is considering various alternatives for this site.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 WARD TRANSFORMER Raleigh, North Carolina Conditions at Proposal ( September 5, 2002): The Ward Transformer site is located near the Raleigh Durham International Airport in a predominantly industrial area of Raleigh, Wake County, North Carolina. The site encompasses an active electrical transformer building/ reconditioning facility constructed in 1964 on 11 acres of previously undeveloped land. A perennial stream bordered by wetlands leads from the property to a recreational lake and fishery. The closest residence, the only one within 1/ 4 mile of the site, is approximately 300 feet northeast of the Ward Transformer property. The site is being proposed to the NPL because elevated levels of polychlorinated biphenyls ( PCBs), dioxins, furans, arsenic, chromium, copper, lead, manganese, and zinc, all attributable to facility operations, have been found throughout the site, and elevated concentrations of PCBs have been detected in surface water downstream of the site, posing a threat to recreational fisheries and wetlands.

Prior to 1972, storm water runoff flow from the facility was uncontrolled. Two impoundments were constructed around 1972 to collect runoff, and in 1979, a retaining wall ( curb height) was constructed around the facility to direct runoff into the impoundment. An onsite treatment plant, installed in 1979, removes PCBs from the impoundment water prior to its discharge. Recent inspections by the North Carolina Division of Water Quality show that the treatment facility is in compliance.

The facility currently incinerates used transformer parts in a permitted onsite burnoff oven/ incinerator and reclaims copper from the resulting ash. Recent inspections by the North Carolina Division of Air Quality indicate that the incinerator is in compliance with its permit. Prior to the installation of the incinerator, transformer parts were burned in the open air to reclaim copper. A concrete area near the incinerator is covered with dark, oily soil. In 1978 and 1979, EPA collected samples on the facility property and from an unnamed tributary and Little Brier Creek downstream from the facility. PCB contamination was found in soil, in the storm water impoundment, and water and sediment collected from the unnamed tributary and Little Brier Creek. No additional action was taken by the EPA on the site until 1993. Prompted by reports of bankruptcy, EPA conducted a removal investigation and no contaminants were detected above removal action levels.

The North Carolina Superfund Section's Preliminary Assessment ( PA) conducted in 1994, and subsequent Site Inspection ( SI) performed in 1995, recommended further action under CERCLA as part of an Expanded Site Inspection. In 1997, samples were collected for the Expanded Site Inspection by the North Carolina Superfund Section. Soil at the wooded rear of the Ward property, outside fencing or curbing, contained PCB 1260, manganese, zinc, 1,2,3,7,8 pentachlorodibenzofuran, and octachlorodibenzofuran. Sediment collected along the shoreline of the impoundment showed PCB 1260. Soil near the incinerator contained Aroclor 1260, dioxins, arsenic, chromium, copper, lead, manganese, and zinc. Aroclor 1260 was also found in sediment samples collected from the unnamed tributary and Little Brier Creek less than a mile downstream of the site.

Status ( April 2003): EPA is considering various alternatives for this site.

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST ( NPL) April 2003 OSWER/ OERR State, Tribal, and Site Identification Center Washington, DC 20460 WOODBROOK ROAD DUMP South Plainfield, New Jersey Conditions at Proposal ( September 13, 2001): The Woodbrook Road Dump site ( Dismal Swamp) is an inactive, non permitted dumping area located in South Plainfield, Middlesex County, New Jersey. The site, which is bisected by Bound Brook, has approximately 34 acres. It is located on two undeveloped properties north of Woodbrook Road. The properties are within wetlands of the Dismal Swamp, a natural wildlife refuge designated as " priority wetlands" by the U. S. Fish and Wildlife Service and the U. S. Environmental Protection Agency ( EPA). Both parcels are currently owned by Texas Eastern Terminal Company ( TETCO), a subsidiary of Duke Energy Corporation. The properties were operated as dumps by previous owners during the 1940s and 1950s, accepting household and industrial wastes until shut down by the New Jersey Department of Environmental Protection ( NJDEP) in 1958. Investigations at the site have revealed the presence of household refuse, building debris, automotive parts, large quantities of bottles, and leaking electrical capacitors.

The leaking capacitors were discovered in September 1999. On September 13, 1999, NJDEP sampled the material inside one capacitor, and recorded greater than 50 parts per million ( ppm) of polychlorinated biphenyls ( PCBs). NJDEP referred the Dismal Swamp site to the EPA for removal action consideration in October 1999. EPA performed an investigation of the site in October 1999, observing that the leaking capacitors were located at a swampy meadow area next to a small stream in Dismal Swamp. EPA collected soil, sediment, and sludge samples in and near the capacitors. Sludge and soil samples showed extremely elevated concentrations of PCBs. Metals analysis was performed for one soil sample, showing elevated levels of lead and smaller amounts of other heavy metals, including mercury, selenium, and thallium. EPA performed oversight of capacitor removal by the property owner on March 8 and 9, 2000. The condition of the capacitors ranged from intact and unrusted to completely rusted or no outside covering.

EPA conducted an Integrated Assessment at the site in July 2000. Surface water, sediment, drinking water well, and background soil samples were collected. The results of the sampling showed PCBs in on site soil samples at elevated concentrations. Lead and other hazardous substances detected in on site soils at elevated concentrations include bis( 2 ethylhexyl) phthalate, benzo( a) anthracene, benzo( b) fluoranthene, benzo( a) pyrene, indeno( 1,2,3 cd) pyrene, antimony, arsenic, barium, cadmium, chromium, cobalt, mercury, and zinc.

PCBs were detected in the surface water and sediment samples collected from the Secondary Tributary at elevated concentrations. The Secondary Tributary receives runoff from the area where the leaking capacitors were found. The surface water and sediment samples contaminated with PCBs delineate approximately 4,370 feet of wetland frontage subject to actual contamination. There are approximately 11 additional miles of wetland frontage along the surface water pathway potentially threatened beyond the contaminated portion. The contaminated stream within the Dismal Swamp converges into Bound Brook, which since 1998 has a fish consumption advisory due to PCB contamination related to a site located within 1.4 mile downstream of the Woodbrook Road Dump site.

The property owner has found evidence of people using the site for recreation. The trails at the site are used for nature hikes. Hunters and recreational vehicle users have been observed in the area where the leaking capacitors where found despite actions taken by the property owner and EPA to limit access. Preventive measures included installation of a fence and warning signs around the disposal area, and installation of guard rails and warning signs at access points to the site.

Ground water threatened by the Woodbrook Road Dump site serves approximately 62,000 people. The downstream surface water pathway includes Bound Brook and the Raritan River, which are classified as fisheries. The total population within 4 miles of the site is approximately 186,000 people. There are approximately 3,000 acres of wetlands located within four miles of the site.

Status ( April 2003): EPA is considering various alternatives for this site.
