              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.

-------
     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.

                                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,  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.

                              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.

                               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.

      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.

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.

                            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.

                                   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.

                               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.

     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

     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

                            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.

                                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.'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

                              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.

      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.

                      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-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

      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.

                           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.
