How to Use the NPL Book
The site fact sheets presented in this book
are comprehensive summaries that cover a
broad range of information. The fact sheets
describe hazardous waste sites on the NPL and
their locations, as well as the conditions
leading to their listing ("Site Description").
The summaries list the types of contaminants
that have been discovered and related threats
to public and ecological health ("Threats and
Contaminants"). "Cleanup Approach" pres-
ents an overview of the cleanup activities
completed, underway, or planned. The fact
sheets conclude with a brief synopsis of how
much progress has been made in protecting
public health and the environment. The
summaries also pinpoint other actions, such as
legal efforts to involve polluters responsible
for site contamination and community con-
cerns.
The fact sheets are arranged in alphabetical
order by site name. Because site cleanup is a
dynamic and gradual process, all site informa-
tion is accurate as of the date shown on the
bottom of each page. Progress is always being
made at NPL sites, and the EPA periodically
will update the site fact sheets to reflect recent
actions. The following two pages show a
generic fact sheet and briefly describe the
information under each section.
How Can You Use
This State Book?
You can use this book to keep informed
about the sites that concern you, particu-
larly ones close to home. The EPA is commit-
ted to involving the public in the decision
making process associated with hazardous
waste cleanup. The Agency solicits input from
area residents in communities affected by
Superfund sites. Citizens are likely to be
affected not only by hazardous site conditions,
but also by the remedies that combat them.
Site cleanups take many forms and can affect
communities in different ways. Local traffic
may be rerouted, residents may be relocated,
temporary water supplies may be necessary.
Definitive information on a site can help
citizens sift through alternatives and make
decisions. To make good choices, you must
know what the threats are and how the EPA
intends to clean up the site. You must under-
stand the cleanup alternatives being proposed
for site cleanup and how residents may be
affected by each one. You also need to have
some idea of how your community intends to
use the site in the future, and you need to know
what the community can realistically expect
once the cleanup is complete.
The EPA wants to develop cleanup methods
that meet community needs, but the Agency
only can take local concerns into account if it
understands what they are. Information must
travel both ways in order for cleanups to be
effective and satisfactory. Please take this
opportunity to learn more, become involved,
and assure that hazardous waste cleanup at
"your" site considers your community's
concerns.

SITE DESCRIPTION
This section describes the location and history of the site. It includes descrip-
tions of the most recent activities and past actions at the site that have con-
tributed to the contamination. Population estimates, land usages, and nearby
resources give readers background on the local setting surrounding the site.
THREATS AND CONTAMINANTS
The major chemical categories of site contamination are noted, as well as
which environmental resources are affected. Icons representing each of the
affected resources (may include air, groundwater, surface water, soil, and
contamination to environmentally sensitive areas) are included in the margins
of this section. Potential threats to residents and the surrounding environ-
ments arising from the site contamination also are described.
CLEANUP APPROACH
This section contains a brief overview of how the site is being cleaned up.
RESPONSE ACTION STATUS
Specific actions that have been accomplished or will be undertaken to clean
up the site are described here. Cleanup activities at NPL sites are divided
into separate phases, depending on the complexity and required actions at the
site. Two major types of cleanup activities often are described: initial,
immediate, or emergency actions to quickly remove or reduce imminent
threats to the community and surrounding areas; and long-term remedial
phases directed at final cleanup at the site. Each stage of the cleanup strategy
is presented in this section of the summary. Icons representing the stage of
the cleanup process (initial actions, site investigations, EPA selection of the
cleanup remedy, engineering design phase, cleanup activities underway, and
completed cleanup) are located in the margin next to each activity descrip-
tion.
SITE FACTS
Additional information on activities and events at the site are included in this

Site Description
The 15-acre Aidex Corporation site is a former pesticide formulation facility located
approximately 7 miles south of Council Bluffs. In 1976, a building used to formulate the
herbicide atrazine and other pesticides was destroyed by a fire. The surrounding soil was
contaminated by water used to extinguish the blaze. In 1980, Aidex filed for bankruptcy. Cleanup
operations were undertaken at the site in 1981. When cleanup began, approximately 3,400 drums
containing pesticides were stored in open areas on the site. A concrete pit in the destroyed
building contained about 2 feet of contaminated water, and a large underground storage tank also
held contaminated materials. Soil and groundwater were contaminated by pesticides spills.
Approximately 600 people live within 3 miles of the rural site. A shallow aquifer underlies the
site and is contaminated. Within a 2-mile radius of the site are 42 shallow domestic water wells.
Site Responsibility:
This site was addressed through
Federal actions.

Proposed Date: 10/23/81
Final Date: 09/08/83
Deleted 10/21/93
Threats and Contaminants
The groundwater was contaminated with atrazine, a pesticide produced at the site. The
soil was contaminated with other pesticides including aldrin and chlordane from
wastes stored at the site and as a result of the 1976 fire. The potential existed for
pesticides to migrate off the Aidex site in either the soil or the groundwater. Flooding
occurring in the area could have facilitated migration of contaminants into the
Missouri River flood plain. The threat of direct contact with or ingestion of
contaminated soil and groundwater has been eliminated.

Cleanup Approach
Response Action Status
Immediate Actions: In late 1981, the EPA constructed a security fence around the
site to restrict access.
Soil and Groundwater: Cleanup technologies selected to address contamination by
pesticides in the soil and ground water included: excavating buried wastes from within
the perimeter of the disposal trench and transporting the wastes off site for disposal
in a secure landfill; grading, when necessary, and seeding the remaining soils; expanding the
monitoring well network by adding three wells to monitor mid-range and deep water quality
downgradient of the site; vacuuming the buildings to remove loose dust from all accessible
interior surfaces and washing floors and walls; and testing monitoring wells annually for 30
years or until a determination is made that the site no longer poses a threat to nearby drinking
water supplies. The EPA and the Army Corps of Engineers removed 20,608 cubic yards of
contaminated soil and buried wastes. The wastes were transported off site, and the site was
backfilled and graded in mid-1987. The State has been collecting annual groundwater samples
from on- and off-site monitoring wells. Since 1987, the EPA collected additional samples from
the interior of the on-site buildings in 1987, 1988, and 1991. Based on these samples, it was
determined that the groundwater does not pose unacceptable risks and no further cleanup is
necessary.
Surface Cleanup: The EPA and the Army Corps of Engineers supervised cleanup
work that consisted of gathering and placing wastes in approved containers, storing
wastes that were spread throughout the yard, draining and decontaminating a buried
tank and waste pit, and constructing a drainage ditch around the site to prevent excessive water
from entering. This work was performed in 1983, and off-site disposal of the collected materials
followed in a second phase, which was completed in 1987.
Site Facts: The Department of Justice, on behalf of the EPA, brought a Federal civil action,
seeking monetary relief against parties potentially responsible for wastes at the site. In 1992, a
Consent Decree was entered by the court that required the parties to pay back the cleanup costs
incurred.
Environmental Progress
The removal of wastes to a secure landfill and the establishment of security measures at the
Aidex Corporation site eliminated the potential for exposure to hazardous materials while cleanup
activities were taking place. Site cleanup has been completed and the EPA has deleted the site
from the NPL.

Site Description
The Des Moines TCE site is an area of contaminated groundwater located southwest of
downtown Des Moines, in the flood plain of the Raccoon River. The surrounding area is
industrial and commercial, with some recreational parklands. The city's public water supply,
which serves approximately 260,000 people, was discovered to be contaminated with
trichloroethylene (TCE) in 1976. The contamination was determined to originate from the city's
groundwater source for its water supply. The Dico Company, who used and disposed of solvent
wastes containing TCE on their property through early 1979, was determined to be a potential
source of the contamination. In 1984, the Des Moines Water Works stopped using the
contaminated portion of the groundwater supply. In 1986, the EPA ordered Dico to undertake
the Agency's selected remedy to protect the city's public water supply. During cleanup activities,
another plume of contaminated groundwater was discovered being drawn into the groundwater
extraction system. An investigation was subsequently initiated to address the contamination
apparently originating to the north and west of the Dico property.
Site Responsibility:
This site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 12/30/82
Final Date: 09/08/83
Threats and Contaminants
The groundwater and soil are contaminated with volatile organic compounds (VOCs),
including tetrachloroethylene, TCE, and vinyl chloride, and pesticides and herbicides
from former industrial operations and waste disposal practices. Accidentally ingesting
or coming into contact with the contaminants poses a health risk.
Cleanup Approach
The site is being addressed in two stages: initial actions and three long-term remedial phases
focusing on site-wide groundwater cleanup, controlling the source of contamination, and
addressing the North Plume.
November 1 994
-------
Response Action Status
Initial Actions: Dico is in the process of cleaning several buildings on their
property that were previously used to formulate and store pesticide and herbicide
products. In addition, Dico is covering the majority of their property with an asphalt
cap to address the threat presented by the surface soil contamination.
Groundwater: The remedy for the protection of the Des Moines water supply
features: collecting contaminated groundwater with extraction wells; isolating the
northernmost section of the public groundwater supply system; treating the
groundwater by an air stripper to remove contaminants; discharging the treated water to the
Raccoon River; and operating the extraction wells until water collected from all monitoring wells
meets EPA drinking water standards for four consecutive months. Dico, under EPA oversight,
designed and built the groundwater extraction and treatment system, which included seven
extraction wells and an air stripping system. Cleanup activities began in late 1987. Dico has and
will continue to operate and maintain the groundwater treatment system until the specified clean
up criteria are achieved.
Source Control: In 1989, Dico began an intensive study of the sources of the
pollution on its property. This investigation showed that contamination by VOCs and
pesticides are of significant concern at the site. The studies for each of these
contaminants will identify sources as well as potential remedies. The study focusing on VOC
contamination is expected to be completed in 1995. The study focusing on pesticide
contamination has been initiated and will be conducted over the next year to determine the
appropriate course of action. Remedies to address each of the contaminants will be selected after
the investigations are completed.
North Plume: In 1988, the EPA began investigating the potential sources of
contaminated groundwater being drawn into the Dico groundwater extraction and
treatment system. The EPA installed additional monitoring wells to the north and west
of the Raccoon River near the Fleur Drive Bridge and north to about 25th and High Street. The
wells have been monitored to determine the extent of contamination and its source(s) and to warn
of any approaching danger to the public water supply. This investigation was completed in the
spring of 1992, and concluded that no further action is warranted as the existing groundwater
extraction and treatment system will capture and cleanup the contaminated groundwater plume.
Site Facts: In 1986, the EPA issued an Administrative Order requiring Dico to design, build,
and operate a groundwater extraction system. Dico signed an Administrative Order on Consent
with the EPA in August 1989 to conduct a study of how to control the potential sources of
contamination at its property.

Site Description
The E.I. DuPont de Nemours & Company, Inc. (County Road X23) site, an industrial waste
dump in a rural area of Lee County, consists of two areas off County Road X23, about 3 1/2
miles southeast of West Point. In the early 1950s, DuPont sent wastes from its nearby Fort
Madison paint plant to the two disposal sites, which are about a mile apart and cover 4 acres.
One is known as the Baier farm subsite and the other as the DuPont/McCarl subsite. DuPont
estimates that between 1949 and 1953, a contractor disposed of 48,000 to 72,000 drums of paint
waste at the two subsites. These wastes were placed in shallow trenches and burned, then the soil
was graded flat. The properties drop off to ravines on the northwestern sides. The company
estimates that 4,500 to 7,000 tons of ash and unburned sludges still may exist on the areas.
Approximately 1,200 people depend on private wells within 3 miles of the site as their sole
source of drinking water. Two creeks about a mile from the site are used for limited recreational
activities. Approximately 160 people live within a mile of the site; 1,250 live within 3 miles,
with the closest population being 500 feet from the site. There are 40 private wells within a mile,
and 330 private wells within 3 miles; the nearest is 500 feet from the site. Water is consumed by
the nearby population as well as local livestock.

Threats and Contaminants
Groundwater and soils were contaminated with heavy metals, including cadmium and
lead, and volatile organic compounds (VOCs) from former disposal activities.
Potential health threats consisted of ingesting contaminated groundwater and directly
contacting both groundwater and soil. Contaminants also could have accumulated in
plants consumed by cattle.
November 1 994
-------
Cleanup Approach
Response Action Status
Initial Actions: In late 1991, DuPont removed contaminated surface material which
could not be stabilized to an off-site, Federally approved disposal facility.
Entire Site: In 1985, the EPA installed three groundwater monitoring at the Baier
subsite. Sampling in 1986 showed elevated concentrations of metals. Downstream
water samples showed similar findings. When the McCarl subsite was studied in
1986, groundwater and soil samples again revealed metals. In 1989, the EPA ordered DuPont to
perform a study of contamination at the site. DuPont completed the study in early 1991. Based on
the results of this study, the EPA recommended stabilization and solidification of contaminated
soil and monitoring of the groundwater as cleanup remedies. DuPont completed the design of
these cleanup remedies in late 1992 and cleanup activities began shortly thereafter. Site cleanup
activities were completed in 1993.
Site Facts: On July 5, 1989, the EPA issued a Unilateral Order to DuPont requiring DuPont to
undertake a study of site contamination and cleanup options at the Baier subsite. In late 1991,
the EPA issued a Consent Decree requiring DuPont to design and conduct the site cleanup.
Environmental Progress
The removal of contaminated surface material, treatment of the contaminated soil, and monitoring
of the groundwater has eliminated risks to public health or the environment from the site. All
cleanup activities are complete. The EPA proposed the site for deletion from the NPL in the
summer of 1994.

Site Description
The 1-acre Electro-Coatings, Inc. site is a plating shop located in Cedar Rapids that has been
operational since 1947. The plant currently performs chromium, cadmium, nickel, and zinc
plating. It lies at the northern edge of Cedar Lake and on the eastern edge of the Cedar River. In
1976, high levels of chromium were discovered in ground water from a nearby cooling water
well. Electro-Coatings, Inc. then began a series of monitoring and cleanup actions in response to
State investigations and requirements. The State required that Electro-Coatings, Inc. determine
the extent of contamination. Electro-Coatings monitored the neighboring off-site wells, installed
on- and off-site monitoring wells, and conducted monthly sampling. Forty of the 46 Cedar Rapids
municipal wells, serving nearly 10,000 people, lie within 3 miles of the site. The nearest
residence is located within a half-mile of the site, and the nearest well lies 2,000 feet away.
Approximately 12,100 residents live within 1 mile of the site; 109,100 live within a 3-mile radius
of the site. The groundwater in the vicinity of the Electro-Coatings site is used for industrial
processes.

Threats and Contaminants
Groundwater is contaminated with volatile organic compounds (VOCs) and heavy
metals from wastewater spills. The chief threat to public health is drinking
contaminated groundwater. The total area of groundwater pollution has not yet been
determined; however, no groundwater contamination has been detected in municipal
drinking water wells. Nearby water bodies, including lakes and streams, potentially
are threatened by site contamination.
Cleanup Approach
The site is being addressed in two stages: initial actions and a long-term remedial phase focusing
on cleanup of the entire site.
December 1 994
-------
Response Action Status
Initial Actions: In 1976, Electro-Coatings, Inc. removed a leaking deep-pit tank and
added 18,000 pounds of ferrous sulfate and 6,600 pounds of sulfuric acid to the area
in an unsuccessful attempt to chemically change the remaining hexavalent chromium
to the less hazardous form of the chemical. In addition, a new pit tank and floor were installed.
In 1977, after a wastewater spill, Electro-Coatings, Inc. installed new monitoring wells to define
the area of groundwater contamination. In the spring of 1992, an existing chromium dipping tank
was taken out of service. Contaminated soil and concrete were removed and disposed of as
hazardous wastes.
Entire Site: After discovering chromium in a neighboring company's well in 1982,
the State required the installation of five more monitoring wells to track the extent and
migration of the contaminant plume. An intensive study to determine the full extent
and nature of the contamination was completed in 1994. A remedy, which includes pumping and
treating the contaminated groundwater, continuous monitoring, and the installation of additional
wells, if needed, was chosen in 1994.
Site Facts: In June 1977, the State issued an Executive Order requiring Electro-Coatings to
install monitoring wells to define the extent of the contaminated plume. In January 1990, Electro-
Coatings entered into a Consent Order with the Iowa Department of Natural Resources to conduct
a site investigation. Concern has been targeted at the potential contamination of Cedar Lake by
Electro-Coatings and other sources.
Environmental Progress
As a result of initial actions, the Electro-Coatings site does not currently pose an immediate
threat to public health or the environment while final cleanup remedies are being planned.

Fairfield
Site Description
The Fairfield Coal Gasification Plant site occupies one city block between West Burlington and
West Washington Avenues in Fairfield. The plant produced a natural gas substitute from coal
from 1878 until 1950. The plant has been owned and operated by Iowa Electric Light and Power
since 1917. Since 1950, the utility has used the site as an operations facility. The main wastes are
poly cyclic aromatic hydrocarbons (PAHs) and volatile organic compounds (VOCs), which are
found in the coal tar left over from the gasification process, and cyanide salts left in the iron
oxide waste produced when the gas is purified. Operators sold some of the coal tar and buried
some in an earthen pit on the site or dumped it in a nearby ditch. Disposal methods for the iron-
cyanide waste are unknown, but it also may have been dumped on site. In 1985, the utility found
that groundwater near the site was contaminated. The utility began a monitoring program to
assure that private wells were unaffected. The EPA became involved in 1987 by conducting an
expanded site investigation, installing and sampling on- and off-site monitoring wells, and
conducting surface and subsurface soil sampling. In 1989, Iowa Electric found that the foundation
for a gas holder was the main source of the groundwater contamination. The gas holder was
removed and destroyed in the 1950s, and wastes were dumped or left in its place. An estimated
1,000 people live within 1 mile of the site; 9,000 live within 3 miles. The local drinking water
supply depends on both surface water and groundwater and serves 11,000 people. There are 23
drinking water wells within a 3-mile radius of the site; the closest is 1,900 feet away. Shallow
and deep groundwater wells are within 2 miles of the site. The closest well uses the shallow
aquifer. Cedar Creek is less than 3 miles downslope of the site and is used for recreation.
Site Responsibility:
This site is being addressed through
Federal, State, and potentially
responsible parties' actions.

In 1985, the utility detected PAHs, including anthracene and pyrene from the coal
gasification processes, in the groundwater near the site. On-site groundwater and soil
contain VOCs such as benzene, toluene, and xylene, and the metals lead and mercury.
Direct contact with contaminated soil and groundwater could pose a risk to public
health.

Emergency Actions: Under EPA monitoring, the utility undertook an emergency
cleanup action, installing a groundwater extraction system. Currently operational, it
is designed to contain and treat the contaminated groundwater.
Groundwater and Soil: Also under the EPA's guidance, the utility completed an
intensive study of groundwater and soil contamination at the site in 1990. The remedy
selected includes excavating and incinerating contaminated soil and source areas,
continuing the groundwater extraction and treatment system, and conducting a pilot study for
possible in-place bioremediation of the contaminated groundwater. The potentially responsible
party completed the technical design for the remedy in mid-1992 and began excavation in mid-
1993. The bioremediation pilot study proved ineffective and was terminated in mid-1993. The
groundwater extraction system achieved health-based standards set by the EPA and the State in
early 1993 and was shut down. The excavation and incineration of soil and source areas is
scheduled to continue until late 1995.
Site Facts: In 1989, Iowa Electric signed an Administrative Order on Consent with the EPA to
conduct additional site investigations. The Utility signed a Consent Decree with the EPA in
March 1991 to perform the technical design and undertake site cleanup activities.
Environmental Progress
Groundwater contamination has been addressed at the Fairfield Coal Gasification Plant site.
Approximately 50 percent of contaminated source material and soil have been excavated. The
EPA has determined that no immediate risks exist while cleanup of the contaminated soil is
completed.

Hospers
Site Description
The Farmers' Mutual Cooperative is an agricultural supply and service business that has operated
at this 6-acre site since 1908. The cooperative lies along the eastern side of the Floyd River and
currently stores bulk grain, fertilizers, and pesticides. In 1984, the Iowa Department of
Environmental Quality found volatile organic compounds (VOCs), herbicides, and grain fumigant
in two municipal wells in Hospers. The Iowa Department of Natural Resources prohibited the use
of these two wells, in addition to a third well nearby. The Hospers municipal wells serve
approximately 1,900 people and are within a 3-mile radius of the site. There are 109 deep and
shallow wells and approximately 1,100 people within 3 miles of the Cooperative. The closest
residence is approximately 100 feet away. Residents use the groundwater for drinking, irrigating
crops, and watering stock.
Site Responsibility: This site is being addressed through
Federal, State, and potentially
responsible parties' actions.
NPL LISTING HISTORY
Proposed Date: 06/24/88
Final Date: 08/30/90
Threats and Contaminants
The groundwater and soil are contaminated with VOCs and various herbicides such as
atrazine. Groundwater contaminants have polluted water under the Cooperative
property and the closed public wells. A sample taken from the Floyd River indicated
the presence of carbon tetrachloride and various pesticides. Although Hospers' public
water supplies currently are not contaminated, public health could be harmed by
drinking contaminated groundwater.
November 1994
-------
Cleanup Approach
This site is being addressed in a long-term remedial phase focusing on cleanup of the entire site.
Response Action Status
Entire Site: In 1987, the Cooperative, under State monitoring, began an intensive
study of groundwater and soil pollution at and around the site. The investigation was
intended to pinpoint the nature and extent of pollution problems and to recommend the
best options for final cleanup. Field work and sampling at the site were completed in late 1991.
The remedy, chosen in 1992, includes a water blending program for the City of Hospers' water
supply, additional monitoring, and measures to reduce contaminants to meet drinking water
standards, if necessary. Treatment or containment of the contaminants will also be implemented
if testing demonstrates that drinking water standards cannot be met.
Site Facts: In 1986, the State issued an Administrative Order, requiring the Cooperative to
conduct a study to determine the type and extent of the contamination and to identify cleanup
alternatives. Partial results were submitted to the State in 1987, and negotiations culminated in a
Consent Order, signed in 1987, providing for a groundwater study and completion of the site
study.
Environmental Progress
The EPA has determined that no immediate actions are required at the Farmers' Mutual
Cooperative site to protect the health of the surrounding population while final cleanup is being
planned.

IOWA
EPA ID# IA7213820445
EPA REGION 7
Des Moines County
miles west of Burlington
Site Description
The 19,127-acre Iowa Army Ammunition Plant (IAAP) site's primary activity since 1941 has
been to load, assemble, and pack a variety of conventional ammunitions and fusing systems.
Wastes currently produced at IAAP consist of various explosive-laden sludges, wastewater, and
solids; lead-contaminated sludges; ashes from incineration and open burning of explosives; and
waste solvents from industrial and laboratory operations. Past operations also generated waste
pesticides; radioactive wastes, which have been removed from the site; and incendiaries. The
Army has identified a number of potentially contaminated areas including the Line 800 Pinkwater
Lagoon, an abandoned 4-acre settling lagoon which received wastewater containing explosives
from 1943 to 1955. The lagoon now holds an estimated 37,000 cubic yards of hazardous sludges.
A second area under investigation involves an earthen and concrete dam across Brush Creek, the
former Line 1 impoundment, which was used from 1948 to 1957. Wastewater flowed through a
3 14-acre sedimentation area where explosives settled out. The liquids then overflowed the dam
into Brush Creek. Approximately 100 people live within 3 miles of the site and obtain drinking
water from private wells within 3 miles of the base. Surface water within 3 miles downstream of
the site is used for recreational activities.
Site Responsibility:
This site is being addressed by the
Army with oversight by the EPA.
NPL LISTING HISTORY
Proposed Date: 07/14/89
Final Date: 08/30/90
Threats and Contaminants
The Army conducted tests from 1981 to 1984 and detected explosives from former
waste disposal practices in the lagoons as well as surface water and wells
downgradient of the lagoon and dam. In 1984, the U.S. Army detected explosives and
lead in creek sediments. People using Brush Creek for recreational purposes may be at
risk due to contaminated waters and sediments. People who come into contact with or
accidentally ingest contaminants may be at risk.
December 1 994
-------
Cleanup Approach
This site is being addressed in two stages: interim actions and a long-term remedial phase
focusing on cleanup of the entire site.
Response Action Status
Interim Actions: The Army has taken the opportunity to exercise removal action
authority to implement interim response actions at selected areas of the site. The
interim responses conducted in 1993 and 1994 include providing alternate water
supplies to affected residences, and the removal of the pesticide pit and sump.
Entire Site: In 1990, the Army began a study to determine the nature and extent of
contamination at the site and identified 43 individual areas requiring investigation.
With the assistance of the EPA, samples were collected from these potential areas of
contamination. After analyzing these samples, the EPA and the Army determined that
approximately three-quarters of the sites needed further investigation. In the spring of 1993, the
Army analyzed water samples from the wells of 54 residences located just south of the IAAP.
Two of the wells were found to contain explosives at levels exceeding health advisory limits.
The Army has offered alternate water supplies to all potentially impacted residents south of the
IAAP and provided connections for all residents who so desired. The selection of a remedy for
the initial group of sites is anticipated during 1995.
Site Facts: A Federal Facilities Compliance Agreement between the Army and the EPA was
signed in 1988; an Interagency Agreement was negotiated in late 1990. The IAAP site is
participating in the Installation Restoration Program, a specially funded program established by
the Department of Defense (DOD) in 1978 to identify, investigate, and control the migration of
hazardous contaminants at military and other DOD facilities.
Environmental Progress
Several interim response actions were performed in 1993 and 1994 that will ensure continued
protection from site contaminants while final cleanup actions are being planned.

The John Deere (Ottumwa Works Landfills) site consists of a 118-acre tract of land and has been
used for the manufacture of farm implements since 1946. From 1911 until 1973, the company
disposed of approximately 3,000 tons of solvents, paint sludges, acids, heavy metals, and cyanide
on site. The site is located 200 feet from prime agricultural land. Approximately 700 people
obtain drinking water from private wells within 3 miles of the site. The main water supply for
Ottumwa, population 27,000, is the Des Moines River; the intake is 4,000 feet upstream from the
John Deere landfills. The river also is used for recreational activities. The city's secondary water
supply, which is used intermittently throughout the year, is Black Lake. It is located 500 feet
downgradient of the on-site landfills.

Threats and Contaminants
Low levels of various heavy metals from site disposal activities have been detected in
the soil, surface water, and sediments. Also, low levels of methylene chloride, a
volatile organic compound (VOC), were detected in the soil and sediments. Potential
risks may have existed for individuals who accidently ingested or came in direct
contact with contaminated soil and surface water.
November 1 994
-------
Cleanup Approach
Response Action Status
Entire Site: Under EPA oversight, the John Deere Company began an investigation
in 1990 to determine the type and extent of contamination. Field work was completed
in late 1990, and the investigation was completed in late 1991. Based on the results of
this investigation, the EPA selected a remedy requiring the John Deere Company to maintain the
existing fence around the site, and to continue monitoring the groundwater to ensure that it
remains safe. In addition, on the property and a State Highway right-of-way, deed restrictions
now limit site use to non-residential activities. The operations and maintenance activities are
scheduled to last into late 1996.
Site Facts: In 1989, John Deere Company entered into an Administrative Order on Consent
with the EPA to conduct an investigation to determine the type and extent of contamination at the
site and to identify alternative technologies for the cleanup. On September 25, 1992, John Deere
Company and the Iowa Department of Transportation signed a Consent Decree with EPA to
implement the selected remedy.
Environmental Progress
Intensive investigations of site conditions have shown that the site does not pose a significant
threat to people and the environment. To ensure that there are no future threats, groundwater
monitoring and land-use restrictions have been put in place. The EPA will continue to monitor
the groundwater at the John Deere (Ottumwa Works Landfills) site to ensure that site conditions
remain safe.

Site Description
The Labounty Site covers 8V2 acres on the Cedar River flood plain. From 1953 to 1977, Salsbury
Laboratories, a manufacturer of veterinary pharmaceuticals, disposed of over 6 million cubic feet
of sludges containing various compounds and metals on the site. This has resulted in the
contamination of a shallow groundwater aquifer that connects to the Cedar River. Investigations
by the EPA and the Iowa Department of Environmental Quality in 1977 and 1978 revealed that
major waste components were being leached and transported from the disposal site by
groundwater to the Cedar River. The State of Iowa ordered the site closed in 1977. That same
year, Salsbury constructed a 24-well groundwater monitoring system. Approximately 10,000
people live within 3 miles of the site. The nearest residence is 1,000 feet from the site. People in
the area use groundwater in the adjacent aquifer for drinking water supplies.

NPL LISTING HISTORY
Proposed Date: 12/30/82
Final Date: 09/08/83
Deleted Date: 10/06/93
Threats and Contaminants
Volatile organic compounds (VOCs) and arsenic leached into the groundwater and
surface water from the disposal site. Drinking contaminated surface water and
groundwater or inhaling volatilized contaminants from the site were potential threats to
individuals prior to cleanup.
November 1994
-------
Cleanup Approach
Response Action Status
Entire Site: The parties potentially responsible for the site contamination installed a
groundwater monitoring system in 1979 and a clay cap in 1980. The capping has
effectively reduced the leaching of wastes located above the water table. However,
capping was not effective in reducing pollutant leaching where wastes were placed below the
water table. Therefore, between 1985 and 1986 under EPA monitoring, the potentially
responsible parties installed an upgradient groundwater diversion wall. The wall diverts
groundwater around the fill material into the Cedar River. Salsbury continues to sample
monitoring wells and the Cedar River. The EPA has conducted field sampling and reviews the
site to ensure that the remedy remains protective. These operation and maintenance activities are
scheduled to last into 1999.
Site Facts: The State of Iowa issued an Administrative Order in 1977 that required the owner,
Salsbury Laboratories, to prevent runoff, cease operations, and submit a plan for the removal of
wastes. In 1985, the EPA and Salsbury entered into an Administrative Order on Consent for the
construction of the upgradient diversion wall and monitoring system in the upper and lower
Cedar Valley aquifers.
Environmental Progress
All cleanup activities have been completed at the Labounty Site. The EPA and the potentially
responsible parties will continue to test the effectiveness of the completed cleanup actions. The
site was deleted from the National Priorities List (NPL) in 1993.

Site Description
The Lawrence Todtz Farm site is located in a predominantly agricultural area of Clinton and
covers slightly over 6 acres. Municipal solid waste and industrial solid and liquid wastes were
disposed of at the site from 1958 to 1975. The E.I. DuPont de Nemours Company, Inc.'s
cellophane plant buried 4,300 tons of liquid waste at the site from 1972 to 1975. The wastes were
reported to include strong acids and bases, plasticizers, resins, alcohols, inorganic salts, paints,
and pigments. The site was closed in 1975 and capped with approximately 2 feet of "red sugar"
clay and topsoil overlay. One hundred people live within 1 mile of the site. Within 1A mile of the
site are 10 farmhouses with private wells for drinking water and approximately 12 mobile homes.
Murphy's Lake (formerly Willow Lake) and Bandixen Lake, located near the site, are used for
recreational activities such as fishing and swimming. Two chemical industrial plants are located

NPL LISTING HISTORY
Proposed Date: 09/05/85
Final Date: 06/10/86
Threats and Contaminants
Groundwater samples from on-site monitoring wells detected heavy metals including
arsenic, barium, and lead; sodium; and volatile organic compounds (VOCs) including
tetrahydrofuran, benzene and toluene from the former waste disposal activities on the
site. Sodium was detected at levels above health guidelines in groundwater samples
collected from area residential wells. Analyses of soil samples collected in 1988
detected arsenic at levels that may have posed adverse health effects. Contamination of
surface water (on-site ponds and nearby lakes) could have occurred if there had been a
release from the impoundment, because the lakes are hydraulically connected to the
shallow sand and gravel aquifer.
November 1994
-------
Cleanup Approach
Response Action Status
Entire Site: The parties potentially responsible for the site contamination installed an
alternate water supply that included drilling a new well to supply water to three area
residents. This was completed in the summer of 1989. Under the EPA's oversight, the
potentially responsible parties have graded the site area, constructed a 2-foot soil cover over the
impoundment, and installed a groundwater monitoring system. These activities were completed in
1991. Monitoring of the impoundment and municipal landfill will continue to ensure the long-
term effectiveness of the cleanup activities.
Site Facts: In November 1990, a Consent Decree between the EPA and the potentially
responsible parties was entered in court. Under this Decree, the parties agreed to perform long-
term cleanup of the site.
Environmental Progress
The installation of an alternate water source, the construction of a 2-foot soil cover, and the
construction of a groundwater monitoring system with chemical-specific action levels have
significantly reduced the potential for exposure to contaminated soil and groundwater at the
Lawrence Todtz Farm site.

Site Description
The Mason City Coal Gasification Plant site is located on approximately 2 1/3 acres in a
commercial and residential area of central Mason City, a north-central Iowa community of
29,000. Mason City Coal Gasification Plant operated from 1900 to 1951 and was demolished in
1952. An electrical substation and a small storage building are all that remain on the site.
During a 1984 sewer installation, oily sludges were discovered in subsurface soil at the site.
Investigations by the current site owner, Interstate Power Company (IPW), revealed three
underground storage tanks containing oily sludge. The tanks and excavated soil were exhumed
and stored on the southeast corner of the site and covered with a membrane cap. Contaminated
soil is also present in the north-central portion of the site. The site is situated on fill material
consisting of sand, gravel, and construction rubble and debris, and is in direct contact with
bedrock. Although the level of the water table fluctuates seasonally, the water table in the fill
material is typically present at depths ranging from 8 to 10 feet below the surface. A portion of
the groundwater flows through the fill and empties into Willow Creek, which is used for public
recreational fishing. Eight Mason City municipal drinking water wells are located within 2 miles
of the site. Approximately 98 percent of Mason City is supplied by the municipal drinking water
supply.

Threats and Contaminants
The soil, on-site waste pile, bedrock, and groundwater are contaminated with
poly nuclear aromatic hydrocarbons (PAHs). Soil samples collected indicate that the soil
is contaminated to a depth of 13 1/2 feet. A series of investigations between 1986 and
1989 by IPW identified high concentrations of PAHs in samples of groundwater taken
from the uppermost aquifer and in samples of Willow Creek sediment downstream
from the site. Ingesting or touching contaminated soil or groundwater could pose a
public health threat.
September 1994
-------
Cleanup Approach
The site is being addressed in two stages: initial actions and a long-term remedial phase focusing
on cleaning up the entire site.
Response Action Status
Initial Actions: In late 1988, the potentially responsible party excavated three
underground storage tanks and surrounding contaminated soil, moved them to the
southeast corner of the site, and covered them with a membrane cap.
Entire Site: In late 1991, the potentially responsible parties undertook a study of
the nature and extent .of site contamination. This study, scheduled for completion in
late 1994, will help to define cleanup alternatives for the site.
Site Facts: IPW signed an Administrative Order on Consent with the EPA in October 1991.
Under this order, IPW agreed to determine the extent of contamination at the site and assist the
EPA in evaluating cleanup options.

Site Responsibility:
This site is being addressed through
Federal actions.
NPL LISTING HISTORY
Proposed Date: 06/24/88
Final Date: 03/30/89
Threats and Contaminants
Monitoring wells on site show that the groundwater is contaminated with heavy metals
including arsenic, barium, chromium, lead, and cadmium from the former process
waste disposal practices. The sediments and surface water of the oxbow lake contain
elevated levels of heavy metals. The groundwater, used by local residents as a
drinking water supply, may be polluted with heavy metals; drinking such tainted water
could be hazardous to public health. About 2 miles south of the site is a wetland used
as a nesting site for the piping plover, an endangered species.
Cleanup Approach
The site is being addressed in two stages: initial actions and a long-term remedial phase focusing
on cleanup of the entire site.
December 1 994
-------
Response Action Status
Initial Actions: In 1990, the EPA removed approximately 1,300 cubic yards of
contaminated soil and sludge from on-site burial pits. This material later will be
immobilized as part of the final cleanup remedy. The EPA also removed any raw
materials found on site and recycled them, where possible. These initial actions were completed
in late 1991.
Entire Site: Due to financial difficulties encountered by the potentially responsible
party in early 1990, the EPA had to initiate studies into the nature and extent of
contamination at the site. The EPA completed these investigations in late 1991 and
chose the following remedy: on-site immobilization of heavily contaminated soil and sludge and
capping of contaminated areas. Design of these cleanup remedies began in 1992 and were
completed in September 1993. Cleanup activities are expected to begin in 1995.
Site Facts: The EPA issued a Unilateral Administrative Order to the potentially responsible
party in late 1989 to perform an investigation of site contamination. Due to financial difficulties,
the party did not comply with the initial actions specified in the Order.
Environmental Progress
The EPA has completed initial actions to address elevated levels of cadmium, arsenic, barium,
and lead in the groundwater by excavating and consolidating buried sludges, abandoned
chemicals, and tanning solutions. These actions will contain the source of contamination and will
reduce the potential for direct contact with hazardous wastes on site until final cleanup is
conducted.

Site Description
The Midwest Manufacturing/North Farm site consists of two areas: North Farm, which is an
unlined disposal cell located 2 miles from the plant; and Midwest Manufacturing, which is the
plant facility. The two areas were combined into the same site because they contain the same
types of wastes and affect the same population. From 1973 to 1981, under Smith-Jones
ownership, the plant was engaged in electroplating special-order stamped metal pieces, a process
that involved using various heavy metals, such as nickel, zinc, and cadmium. Prior to a
wastewater treatment plant being brought on line in 1977, the electroplating waste from the plant
was discharged directly into the North Skunk River. From 1977 to 1978, the sludge produced by
this process was disposed of in an unlined cell at the North Farm area. From 1979 to 1981,
trenches at the Midwest Manufacturing area near the plant received the sludge produced by the
treatment process. In 1982, the EPA collected sludge samples from the disposal trenches at both
areas. Cadmium was the only metal which was found to be present in the soils above naturally-
occurring levels. No elevated metals were present in soil samples taken from the North Skunk
River downgradient from the plant. A ground water sample collected from Well #1 was found to
contain levels of zinc less than the proposed level for lifetime exposure. During the EPA's 1987
site visit, a man-made drainage ditch was discovered to the west of the disposal trench at the
plant. The sediments in this ditch were covered with a black, oily substance that had a petroleum
odor. Stressed vegetation and an oily substance floating on top of the water were observed in a
marshy area located on the western end of the plant property. In a 1989 site visit, it was noted
that the drainage ditch had been covered and a plastic drain pipe had been placed in bottom of the
ditch. The plant currently manufactures high-speed flywheel ring gears and assemblies for
automobiles. Approximately 700 people depend on wells located within 3 miles of the site for
their drinking water supply.

-------
Threats and Contaminants
During sampling in 1982, the Midwest Plant city well #1 showed elevated levels of
zinc from the former waste disposal activities. Groundwater samples from plant site
monitoring wells found elevated levels of volatile organic compounds (VOCs) such as
vinyl chloride, trichloroethylene, and dichlorothylene and the heavy metals cadmium
and nickel. Surface soils at both areas contain elevated levels of heavy metals.
Adverse health effects could result from ingesting vegetables grown on contaminated
soils or watered with contaminated groundwater. In the event that contaminated
groundwater were to be consumed, the site may pose a health risk to area residents.
Cleanup Approach
This site is being addressed in two long-term remedial actions focused on the cleanup of the
Midwest Manufacturing Area and the North Farm Area.
Response Action Status
Midwest Manufacturing Area: The EPA concluded a study of the nature and
extent of contamination of the area in 1990. The 1991 remedy included installation
of a groundwater extraction and treatment system and capping of the plant site
disposal trench. The EPA conducted a pump test in preparation for the cleanup design and
determined that the aquifer was less permeable than previous data indicated, which lengthens the
cleanup time and increases the site cleanup costs. Subsequently, the EPA amended the remedy to
include deed restrictions, installation of groundwater monitoring wells, perimeter fencing and
regular groundwater sampling of both monitoring wells and supply wells within a 1 mile radius
of the plant site. Design of the cleanup was completed in early 1992. Cleanup activities are
expected to begin in 1995.
North Farm Area: The EPA concluded a study of the nature and extent of
contamination of the area in 1988. The 1988 remedy included removal of soils
containing cadmium above the concentration of 13 mg/kg. The EPA has re-evaluated
risk data and determined that the site, in its present conditions, poses no current risk to human
health and the environment. Future risks can be prevented by using institutional controls which
would prohibit certain future land use, such as vegetable gardening and prevent the installation of
a water supply well. EPA amended the remedy selection to include deed restrictions and
groundwater monitoring of the three existing monitoring wells. Design of the cleanup was
completed in mid-1991. Cleanup activities are expected to begin in 1995.
Environmental Progress
The EPA has determined that the site required no immediate actions to reduce the potential for
exposure to contaminants while final cleanup remedies are being planned. The EPA will monitor
the progress of the cleanup actions to determine whether they remain protective of human health
and the environment.

The Northwestern States Portland Cement Co. (NWSPCC) site covers 150 acres of a 250-acre
parcel of land in Mason City. The NWSPCC began limestone mining operations in 1908. The
company ceased the mining in 1950 and abandoned the quarry west of the plant. In 1969, the
NWSPCC began to use the quarry for the disposal of waste kiln dust containing hydroxides,
potassium, chromium, and sulfates. An estimated 2 million tons of waste kiln dust were disposed
of in the quarry. Over the years, the water level rose approximately 2 feet per year, filling in the
quarry so that it held approximately 420 million gallons of water. Rainwater runoff drains from
the quarry into adjacent Calmus Creek, a tributary of the Winnebago River. The Iowa
Department of Natural Resources (IDNR) conducted an investigation in 1984, when a citizen
became concerned over the Winnebago River turning white. Calmus Creek was found to have a
higher than normal pH level. The Mason City municipal wells are within 3 miles of the site and
serve approximately 30,000 people. About 300 people obtain their drinking water from private
wells within P/2 miles of the site. The municipal wells are connected to the deep Jordan aquifer.
The private wells are served by the Cedar Valley aquifer. Calmus Creek and the Winnebago

Threats and Contaminants
The groundwater is contaminated with sulfates, sodium, and elevated pH from the
former process waste disposal practices at the site. Although the groundwater is
contaminated, municipal and private drinking water wells are not polluted. If the
contaminant plume had migrated from Calmus Creek and into the Cedar Valley
aquifer, the private wells could have become contaminated and pose a health hazard to
people who use them. Sediments and soils are contaminated with higher than normal
pH. Calmus Creek is contaminated with higher than normal pH, and people who use
the creek for recreation or eat fish from it may be at risk. The increased pH found in
soil, sediments, and surface water of the quarry is considered caustic; therefore,
coming in direct contact with these substances would pose a health risk.

Cleanup Approach
Response Action Status
Initial Actions: The State ordered the NWSPCC to stop discharges into Calmus
Creek, and the company complied by installing a system that intercepts the flow and
pumps the water back into the quarry. In 1987, the company began treating the
surface water before discharging it into the creek.
Entire Site: The NWSPCC has pumped most of the water from the quarry. The
NWSPCC also conducted an investigation, under State supervision, to determine the
extent of contamination at the site. The investigation was completed in 1990. Based on
the results of the investigation, EPA selected a cleanup remedy. Along with pumping the water
from the quarry, the remedy includes construction of a permanent drain system in the quarry to
collect precipitation runoff and groundwater inflow; installation of a cap over the quarry area
filled with waste kiln dust to minimize infiltration through to kiln dust; installation of bedrock
dewatering wells to collect contaminated groundwater to prevent migration of contaminated
groundwater, and to maintain groundwater levels; installation of kiln dust dewatering wells, if
necessary; treatment of contaminated waters and final discharge into Calmus Creek; and
continued operation of a dewatering system. The design of these technologies by the NWSPCC
began in 1991 and was completed in late 1992. Construction of site remedies was completed in
1993.
Site Facts: In 1985, the State issued an Administrative Order to the NWSPCC to stop
discharges into Calmus Creek. In addition, the Order instructed the company to conduct a study,
under State supervision, to determine the effect of the quarry on the environment. This study was
completed in 1987. In 1989, the State issued an Administrative Order to the NWSPCC to
conduct an additional site study, which was completed in 1990.
Environmental Progress
All construction at the site is complete. Pumping the water from the quarry and treating surface
water prior to release to Calmus Creek has reduced the potential for exposure to contaminated
water and sediments at the Northwestern States Portland Cement Co. site while operation of the
dewatering system continues.

Key City Coal Gasification Plant
Site Description
The Peoples Natural Gas Co. site is located in Dubuque and covers approximately 5 acres. From
1890 until 1954, the Key City Gas Company owned and operated this gas plant, where a natural
gas substitute was produced from coal. In 1954, the North Central Public Service Company took
over operations until 1957, when Peoples Natural Gas Company assumed ownership of the site.
Peoples used the site as a storage and maintenance area and did not manufacture gas. It later sold
a portion of the site to the City of Dubuque, which operates the Dubuque Municipal Garage on
the site. The Iowa Department of Transportation owns the remainder of the site. Two waste
products resulting from coal gasification are of primary concern: coal tar sludges and spent iron
oxide. Coal tar sludges were produced during the coal or coke combustion and during the oil
injection processes, and spent iron oxide wastes were produced during the gas purification
process. Spent iron oxide wastes, removed from the three gas cleaning boxes (purifiers), were
dumped behind two gas holding tanks on the site at least twice a year. Spent iron oxide and other
wastes were deposited in the northeastern section of the site. Coal tars were removed from the
gas in the wash box and condenser. These wastes either were sold or disposed of in pits or
holding tanks. Two coal tar waste storage tanks were used at the Key City plant, one
aboveground and one below. Both tanks have been removed. Evidence of materials left in the
underground tank, as well as migration of waste out of the tank, is supported by a study done by
the Iowa Department of Transportation in 1983 while conducting a right-of-way survey for the
proposed extension of U.S. 61. An estimated 60,000 people obtain drinking water from
municipal wells within 3 miles of the site. Approximately 2,400 people live within a mile of the
site, and 21,000 people live within 3 miles. The Mississippi River is approximately 500 feet east
of the site. Surface water downstream is used for industrial and recreational activities. A wildlife
and fish refuge is 2 miles downstream, and wetlands are within „2 mile of the site.

Threats and Contaminants
Phenols, poly cyclic aromatic hydrocarbons (PAHs), and inorganic chemicals from the
gasification process wastes were detected by the State in on-site wells. Soil samples
collected at the site in 1983 also contained phenols, PAHs, and inorganic chemicals.
Accidental ingestion of or direct contact with contaminated soil or groundwater may
pose potential health threats to individuals. No private drinking water wells have been
identified in the area. The wetlands and the wildlife and fish refuge may be threatened
by runoff from the site.
Cleanup Approach
The site is being addressed in two stages: immediate actions and a long-term remedial phase
focusing on soil and groundwater cleanup.
Response Action Status
Immediate Actions: Under EPA oversight, potentially responsible parties for the
site contamination removed the contaminated coal tar sludges and soils containing
contaminants above human-health standards from within the construction corridor for
U.S. Highway 61. Contaminated soil currently is being incinerated off site. Incineration of these
soils is expected to continue through late 1994.
Soil and Groundwater: A study of the extent and type of groundwater and soil
contamination also was completed by the potentially responsible parties. A remedy
that requires excavation and incineration of contaminated soils, and pumping and
treating contaminated groundwater, was selected in 1991. Restrictions on land and groundwater
use also will be implemented. Design of the remedy was completed in early 1994. Excavation
of contaminated soils for the remaining portion of the site will be initiated in the spring of 1995
and is scheduled to be completed in late 1996.
Site Facts: The EPA signed an Administrative Order on Consent with Midwest Gas (of Iowa
Public Service, a successor corporation of Key City Gas Co.), the Iowa Department of
Transportation, and the City of Dubuque in 1989. The Order required the parties to remove or
treat any contaminated soil. It also required completion of an investigation to determine the need
for treatment of residual soil and for groundwater treatment. The EPA signed a Consent Decree
with Midwest Gas, the Iowa Department of Transportation, the City of Dubuque, and Enron on
December 28, 1992, which requires the parties to conduct the design of the remedy and cleanup
activities.

Other Names:
Union Carbide Disposal
Site Description
The 40-acre Red Oak City Landfill site is an inactive landfill located within an old limestone
quarry in a rural setting. Of the 40 acres, 20 acres were used for disposal. The landfill is
bounded on the west by Parkwest Road and on the east by the East Nishnabotna River.
Quarrying activities at the site were conducted by strip mining from the late 1940s to the early
1960s. The City of Red Oak purchased the site property in 1962 and converted it into a
municipal landfill. From 1962 until 1974, municipal waste and industrial waste including
hazardous substances were deposited in the landfill. There is a thin layer of soil covering the
landfill, and at some points, waste materials, including 55-gallon drums, are exposed to the
surface. The eastern portion of the landfill, adjacent to the East Nishnabotna River, is being
eroded as a result of river bank undercutting and surface water runoff. Approximately 7,000
people within 3 miles of the site depend on groundwater as a source of drinking water. The
nearest residence uses a private well 1,800 feet away from the landfill. There are 250 people
living within a mile of the site.

Threats and Contaminants
VOCs including toluene and xylene and heavy metals including chromium, lead, and
barium from the landfilling practices have been detected in the soil, groundwater, and
surface water at low concentrations. The sediments near the landfill contain toluene.
Ingestion or direct contact with the contaminated groundwater, surface water, soils or
sediments could be hazardous. The landfill is situated in permeable soil, which
increases the chances of the groundwater becoming contaminated.
Cleanup Approach
The site is being addressed in a long-term remedial phase focusing on cleanup of the entire site.

Site Description
The Shaw Avenue Dump site, an 8-acre city dump, is located in southeastern Charles City,
approximately 500 feet east of the Cedar River. The City owns the site and operated it as a
municipal waste dump without a permit. Two areas in the northern half of the site were used
from 1949 to 1953 to dispose of 14,000 to 28,000 cubic feet of arsenic-contaminated solid waste
generated by Salsbury Laboratories in the production of animal Pharmaceuticals. Sludge from the
Charles City wastewater treatment plant, which received liquid wastes discharged from Salsbury,
was placed in the northern waste cells and in an undefined area on the southern portion of the
site. The northern disposal area no longer is in use and has been covered with soil and vegetated.
Between the southern and northern areas, trenches were used for disposing of lime sludges from
the drinking water treatment plant. The City and the public used this area for open burning of
wastes. The site is within a large residential area. A high school is located approximately 1,000
feet north of the site. Students use a stadium within 500 feet of the northern waste disposal cells.
One residence, 1,500 feet southeast of the site, uses a private well for domestic purposes. The
Charles City municipal water supply system, within 2 miles uphill of the site, serves 8,800
people. The Cedar River flows through Charles City and is used for recreational fishing,

November 1994
-------
Cleanup Approach
The site is being addressed in two long-term remedial phases focusing on cleanup of chemical fill
and contaminated soil, and cleanup of the groundwater.
Response Action Status
Chemical Fill and Contaminated Soil: The EPA began an investigation of the
site and its cleanup alternative in 1987. The parties potentially responsible for site
contamination took over the investigation in 1988 and completed it in late 1991. In
early 1992, the potentially responsible parties began cleanup activities. The remedy initially
called for stabilization of chemical fill and contaminated soil, however, treatability tests indicated
that stabilization would not be effective. All contaminated materials have now been removed off
site to a federally-approved landfill as described in the contingency remedy. Cleanup of the
contaminated soil and chemical fill was completed in early 1994.
Groundwater: An investigation of the nature and extent of groundwater
contamination is expected to begin in 1997, and will result in the selection of final
cleanup remedies.
Site Facts: In March 1987, the EPA sent letters notifying Salsbury Laboratories and Charles
City of their potential responsibility and requested information about their use of the site. A
Consent Order was completed on May 26, 1988. Under this Order, the potentially responsible
parties were required to conduct an investigation to determine the type and extent of
contamination on the site.
Environmental Progress
The removal of contaminated soils from the Shaw Avenue Dump site has reduced the risk of
exposure to hazardous materials pending the start of investigations that will lead to the selection
of a groundwater remedy.

Sheller-Globe Corp. operated an industrial landfill and solvent burning area from 1947 to 1970.
The 5-acre site was filled in and sold in 1980 to an individual who built a home on it and drew
water from a 300-foot-deep on-site well. The water from the well contains lead and zinc, possibly
from the distribution lines. The homeowner permanently relocated in the fall of 1991. The site is
no longer used for residential purposes. In the past, the Sheller-Globe Corporation manufactured
rubber products, including automobile weather stripping, at a facility located in Keokuk. Liquids,
sludges, and rubber stripping from the operation were deposited on site with no system for
diverting surface runoff. According to the company, among these wastes were at least 1,000
drums of paint sludge, volatile organic compounds (VOCs), isopropyl alcohol, and resins
containing fluorocarbons. Waste material, including solvents was routinely burned in the open
and buried. In 1987, the EPA found heavy metal and VOC contamination in soil, groundwater,
and surface water during testing. Previously, an estimated 1,125 people obtained their drinking
water from private wells within 3 miles of the heavily wooded rural site. Most people now obtain
drinking water recently made available from one of two rural water districts.

Cleanup Approach
Response Action Status
Initial Action: As a preliminary action, a 2-foot thick clay cap was placed over the
disposal area, and floating hydrocarbons are removed from the top of the water table
on a monthly basis. This action has reduced the floating hydrocarbons from 2 feet
down to only intermittent presence.
Source Control: After evaluating alternative cleanup methods, the EPA selected a
remedy for source control. The potentially responsible parties are excavating
contaminated soils and separating solid and liquid waste for off-site incineration,
recycling, or disposal. An estimated 30,000 to 50,000 cubic yards of contaminated soils are
being treated using a bioremediation process in surface impoundment units. Treated soil will be
placed back into the excavation area and covered. Leaching standards for soils have been
established. The potentially responsible parties completed design activities for the cleanup in
1991. Site cleanup activities began immediately thereafter. Construction was completed in
August 1994. The soils system is now in the operation and maintenance phase, which is
expected to last into 1997.
Ground water: To address groundwater contamination, the EPA chose pumping
and air stripping contaminated groundwater, with discharge to the nearby stream.
VOCs are released into the atmosphere from the groundwater treatment process.
Health-based standards for groundwater were established. The potentially responsible parties
began construction of the treatment system in 1991. Construction was completed in October
1992. The groundwater system is now in the operation and maintenance phase, which is
expected to last through at least 1999 to reach established health-based standards.
Site Facts: The site currently is listed on the State Abandoned or Uncontrolled Sites Registry
(SAUSR). Substantial changes or transfer of property on this registry is prohibited without
written approval of the Director of the IDNR.
Environmental Progress
By placing a cap over the areas of greatest contamination, removing the floating contaminants
from standing water, implementing the groundwater treatment system, and implementing the
source control remedy, the Vogel Paint & Wax Company site no longer poses an immediate
threat to the public or the environment.

Site Description
The former Waterloo Coal Gasification Plant manufactured gas for lighting and heating purposes
from 1901 to 1956 in Waterloo, Blackhawk County, Iowa. When operational, the coal
gasification operation occupied approximately 4 1/2 acres. The majority of the site is located
along the Cedar River, south of Sycamore Street between Union and Elm Streets. A railroad
right-of-way runs through this portion of the site. Plant diagrams also indicate that an area
located north of Sycamore Street and east of Union Street housed gas holders. During the time
period that operations occurred, several power companies held title to the parcels that comprise
the site. Since discontinuation of operations in 1956, certain parcels have been sold to public and
private parties. The majority of the site is presently owned by a utility company, Midwest Power
Systems, Inc., a subsidiary of Midwest Resources, Inc. The plant was dismantled between 1964
and 1967. Two waste streams generally associated with manufactured gas plant sites are of
primary concern: coal tar residuals from the gasification process and cyanide residuals from the
purification process. Exact disposal methods for these wastes are unknown; however, initial
investigations indicate soil and groundwater contamination. The nearest downgradient bedrock
wells servicing Waterloo and nearby Evansdale are located 1 3/4 miles south and 3 miles
southeast of the site, respectively. Approximately 74,800 people obtain drinking water from

groundwater may pose potential health threats to individuals. The potential also exists
for adverse impacts on wetlands and associated wildlife due to contaminant migration
from the site to the Cedar River.
Response Action Status
Initial Actions: Midwest Gas agreed to develop the necessary work plans and
conduct a removal action to identify, excavate, process, and incinerate or dispose of
all coal tar, visibly contaminated coal tar-impacted soils and source material. EPA
will review the documents prepared by Midwest Gas and provide oversight during certain stages
of on-site activities. A comprehensive public and private well survey also will be conducted by
Midwest Gas. Site preparation, test trenching, excavation and soil processing activities were
initiated in the summer of 1994. Cleaned structural debris will be disposed of at the Blackhawk
County Sanitary Landfill. The processed soil will be transported to the George Neal Electrical
Generating Station in Sioux City, Iowa for incineration. The majority of the source material is
expected to be excavated, processed, and transported off-site during the fall of 1994 and the
spring of 1995.

The White Farm Equipment Co. Dump site occupies approximately 20 acres along the northern
border of Charles City. The dump is located in an old sand and gravel pit that is bordered by
low-lying areas and farmland. Tractors and other farm equipment have been manufactured near
the dump since the early 1900s. White Farm Equipment operated on land leased from H.E.
Construction Co. until it filed for bankruptcy in 1980. Allied Products Co. purchased the
operation in late 1986. Starting in the 1920s, White Farm's operations generated foundry sand,

Cleanup Approach
The site is being addressed in a long-term remedial phase directed at cleanup of the entire site.
Response Action Status
Entire Site: One of the parties potentially responsible for the contamination
investigated the nature and extent of contamination. The investigation included
characterization of waste in the landfill, determination of contamination spread by
rainwater runoff, detection of contamination spread by air, detection of contamination spread by
dissolved metal, and determination of groundwater movement and evaluation of possible
connections between the shallow aquifer and the drinking water aquifer. The EPA chose a
compacted soil and vegetative layer cap as the cleanup measure in 1990. The potentially
responsible parties began cleanup actions in mid-1994. Cleanup is scheduled for completion in
late 1994.
Site Facts: In 1989, the EPA and two parties potentially responsible for the contamination
signed an Administrative Order on Consent. In that Order, one of the parties agreed to take
responsibility for the site investigation to determine the nature and the extent of the
contamination. In 1991, a Consent Decree was signed by the party to design and perform site
cleanup. The Consent Decree required sampling of groundwater. The initial round of sampling
indicated no contamination in the groundwater. A second round of sampling is underway to
confirm the original results.
Environmental Progress
After adding the site to the NPL, the EPA determined that no immediate actions were required.
Final cleanup actions are scheduled for completion in late 1994.
