DESCRIPTIONS OF 25 SITES IK HOHJtaKL) UPDKIE f 10
TO THE NATIONAL PRIOK1T1ES LEST
This document consists of descriptions of 25 sites proposed in October
1989 as Update #10 to the National Priorities List (NFL). 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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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..

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.

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.

KERR-MCGEE CORP. (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.

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.

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.

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.

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.

ELtSWCRffl AIR FORCE BASE
Rapid City, South Dakota
Ellsworth Air Faroe Base covers 4,858 acres on the border of Meade and
Permingtcn Counties, South Dakota, approximately 11 jpiles northeast of Rapid
City and 1.4 miles north of Box Elder. 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.

WILLIAMS PIPE LINE CO. 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.

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.
