SITE DESCRIPTION

Approximately 24,000 people live in the City of Hastings. Like most communities, industries
have expanded to areas outside of the city limits. Farms and pastures surround the urban area,
and many private and public wells lie within a 3-mile radius of the city. Ground water is used to
irrigate crops, water stock and provides water for home and business use. A nearby stream and
lake are used for recreation. Concerns regarding volatile organic compounds (VOCs), including
commercial grain fumigants in the Hastings' city water supply, were investigated by the State of
Nebraska in 1983. As a result, Hastings took two municipal supply wells out of service and
placed other contaminated wells on a standby basis. Community Municipal Services, Inc.
(CMS), a private water supply system formerly serving the areas east of Hastings, also took two
of its three wells off-line due to pollution. Industrial solvent chemicals and commercial grain
fumigants have migrated downward through the soils and are being carried by the ground water
which flows generally to the east. Testing conducted by the City and the State assures that the
public water supply provided by the City meets Safe Drinking Water Standards.

EPA designated the contaminated area generally outlined by the boundary of the ground water
contamination as the Hastings Ground Water Contamination Site. The site includes properties
within the central industrial area of the City of Hastings and properties situated east of the city
limits including the former Naval Ammunition Depot (NAD). The Hastings site was placed on
the National Priorities List in 1986.

The site has been divided into seven subsites for investigative and remediation purposes based
on geographic and contaminant source area characteristics. The seven subsites are: Well No. 3,
Colorado Avenue, Second Street, North Landfill, FAR-MAR-CO, South Landfill and the former
NAD. The Adams County portion of the former NAD is known as the Hastings East Industrial
Park. Cleanup of the former NAD is being addressed by the Army Corps of Engineers. The

-------
remaining subsites are being addressed by EPA and/or potentially responsible parties under
various subsite-specific and "Area-Wide" actions.

Due to the size and complexity of the Hastings site, the following site description is organized
into three geographic areas: Central Industrial Area; Commercial Area and closed city landfills;
and Hastings East Industrial Park/former Naval Ammunition Depot. To facilitate the
management of investigation and response actions, "Operable Units" have been defined for each
of the subsites.

Central Industrial Area:

This area encompasses commercial and industrial properties situated in the heart of Hastings,
along the Burlington-Northern railroad right-of-way. The three subsites that make up this area
are Well #3, Colorado Avenue, and Second Street. The Well #3 subsite, named for M-3, one of
the city wells taken out of service, is contaminated with carbon tetrachloride (CC14), a grain
fumigant. A second plume of contaminated ground water containing chlorinated industrial
solvents trichloroethylene (TCE), trichloroethane (TCA), and perchloroethylene (PCE) was
identified by EPA's investigation and is being managed by a local manufacturing firm. At the
Colorado subsite, the soils and ground water are contaminated by three industrial solvents, the
most significant being TCE. A vapor degreasing operation at the industrial facility located at
108 S. Colorado Avenue has been identified as the source of solvent releases to the environment
during the 1960's and 1970's. Contamination at the Second Street subsite was identified in 1988,
during EPA's investigation of Colorado Avenue subsite. Pollution from an old coal gas plant
operation was detected in the soil and the ground water at the Second Street subsite.
Contaminants include benzene, toluene, ethyl benzene, xylene, styrene and polycyclic aromatic
hydrocarbons (PAHs).

Commercial Area and Closed City Landfills:

This area, situated at the eastern edge of Hastings, contains the North Landfill, FAR-MAR-CO
and South Landfill subsites. Studies have revealed that the FAR-MAR-CO and North Landfill
subsites are polluting downgradient wells with VOCs. The North Landfill originally was a local
brickmaker's clay pit. Hastings operated it as a landfill in the early 1960s to dispose of various
municipal and industrial wastes. Operators of the FAR-MAR-CO subsite stored and handled
agricultural products, mostly grains, for more than 30 years. VOCs, including toxic grain
fumigants, have seeped into the soils and ground water. Grain dust explosions and spills from
fumigant equipment on the subsite have contributed to the problem. While investigating soils at
the FAR-MAR-CO subsite, EPA discovered trichloroethane (TCA) contamination on a portion
now owned by a different company. TCA is a solvent used to clean metals. This area became
known as the TCA Contamination Area, and was cleaned up by the new owner in 1989. The
South Landfill was operated by the City of Hastings during the 1960s and 1970s, to dispose of
municipal and industrial wastes. Sampling by EPA revealed the presence of TCE, PCE and
vinyl chloride (VC) in the ground water. The subsite is bounded on the east by farmland. Also,
located farther to the east of the South Landfill is the former NAD.

Hastings East Industrial Park (HEIP) /Former Naval Ammunition Depot (NAD):

The former NAD consisted of more than 72 square miles and was located 2 miles east of
Hastings. This facility extends into Clay County and includes properties that have been

-------
transferred to private parties and various government agencies. The 48,000-acre NAD was used
for loading armaments until the early 1950s, and later for the demilling of armaments until it was
decommissioned in the early 1960s. The U.S. Army Corps of Engineers is conducting studies at
the site under the authorization of the Department of Defense (DOD). The major contaminants
identified in the soils include volatile organic compounds (VOCs), explosives, PAHs, and
metals. Cleanup of the surface soil contamination on 2,600 acres of the HEIP has been
completed by the Corps. Although contaminants that have been detected are generally consistent
with the chemicals used by the Navy operations, the industries established in the HEIP since the
1960s may have generated some of the VOCs detected.

Site Responsibility:

This site is being addressed through Federal, State,
local, and potentially responsible parties' actions.

THREATS AND CONTAMINANTS

03

Ground water and soils at the various subsites are contaminated with a wide range
of VOCs and other organic compounds. Investigations at the former NAD subsite
showed heavy metals, explosives and VOC contamination in soils. Additionally,
soils and ground water at the Second Street subsite contain PAHs. Surface soil
contamination at the NAD has been addressed through cleanup actions. Through a
combination of cleanup activities and limited access soils at the other subsites
should not present a current risk to human health. The water provided by the City
meets federal safe drinking water standards. The city of Hastings has implemented
an Institutional Control Area (IC A) to minimize the potential for exposure to
contaminated drinking water. The ICA is discussed under the section titled
Area-Wide Hastings Site. There is insufficient information to determine if there
are exposures for certain users of private wells located outside the city limits either
because access for sampling the private well was denied or because private wells
are located beyond the ICA..

CLEANUP APPROACH

Response Action Status

To date, source control response actions have been initiated at all of the Hastings subsites.

-------
Source control response actions utilizing Soil Vapor Extraction (SVE) have been performed at
the Well No. 3, Colorado Avenue, Second Street, FAR-MAR-CO, North Landfill and former
NAD subsites. Additionally, a clay cap was installed at the North Landfill and an
evapotranspiration cap was installed at the South Landfill in July 2005. Ground water response
actions have been initiated at the Well No. 3, Colorado Avenue, Second Street, FAR-MAR-CO
and former NAD subsites. Studies are ongoing to evaluate downgradient ground water quality
issues attributable to the North Landfill and South Landfill subsites. The ground water actions
at Well No. 3, FAR-MAR-CO and Second Street have been or are being designed to contain or
monitor ground water concentrations that exceed maximum contaminant levels (MCLs) or,
where there is no MCL for a constituent of concern (COC), the 1 in 1,000,000 cumulative excess
cancer risk level. The FAR-MAR-CO ground water action will have the effect of controlling the
North Landfill plume. Treatment of ground water contaminated by both the FAR-MAR-CO and
North Landfill subsites will reduce contamination to below MCLs. The ground water response
actions at the Second Street subsite were initiated as two removal actions, and later expanded to
include enhanced in-situ bioremediation in the remaining areas of the contaminant plume. Two
interim remedial actions being implemented at Colorado Avenue are designed to contain and
treat ground water concentrations that correspond to values estimated to exceed 1 in 10,000
cumulative excess cancer risk.

The Well #3 Subsite is located in the Central Industrial area of Hastings. In 1989, EPA issued an
Interim Action Record of Decision (ROD) selecting soil vapor extraction (SVE) as the
technology to remediate the soils contaminated with carbon tetrachloride. EPA entered into a
Superfund State Contract (SSC), with the State of Nebraska and began full-scale soil remediation
in July, 1992. In July, 1993, EPA and the state determined that remediation of the soils was
complete. The State of Nebraska and EPA entered into a second SSC to provide a cost share for
the ground water remediation. A modification to the second SSC allowed the City of Hastings to
enter into a Cooperative Agreement with EPA. The City of Hastings operated this ground water
remediation system. The ground water cleanup for Plume 1 began in 1995, with the installation
of an air stripper to treat ground water. EPA installed an irrigation system at a Hastings city park
in the summer of 1998, for beneficial reuse of this extracted water (Operable Unit No. 13). This
remedial action was completed in 2004 when ground water monitoring indicated that the carbon
tetrachloride present in the aquifer had been remediated to the MCL. Plume 2, was addressed
by Dutton-Lainson under an Administrative Order on Consent (AOC) to conduct a soil vapor
extraction (SVE) removal cleanup. These removal activities began in March, 1996. The AOC
also required that Dutton-Lainson monitor ground water for the Plume 2 contaminants on a
quarterly basis. These actions were complete in 1999. In May 2001, EPA released its final ROD
for the Well #3 Subsite selecting no further action for OUs #07, #17 (source control operable
units) and #13 (Plume 1 ground water operable unit). For OU#18 (Plume 2), EPA selected the
continuation of the Plume 1 remedy at the former decommissioned well until MCLs are attained
and verified for the Plume 2 contaminants. EPA and Dutton-Lainson Company signed a Consent
Decree (CD) to perform this work. Dutton-Lainson began operating the system at M-3 in May
2003, and initiated ground water monitoring in June 2003, and samples the ground water 2 times
a year.

The Colorado Avenue Subsite is located in the central portion of the City. In 1988, EPA issued
an Interim Action Record of Decision (ROD) in which it selected soil vapor extraction (SVE)

-------
technology to cleanup approximately 800,000 cubic yards of contaminated soil. On September
28, 1990, after failing to negotiate an agreement to implement the (SVE) technology with the
Colorado Avenue Potentially Responsible Parties (PRPs), EPA issued a Unilateral
Administrative Order (UAO) to Dravo Corporation and Desco Corporation, the subsite PRPs, to
construct and operate the SVE system. The Phase I SVE system began operation in July, 1996.
In 1991, EPA issued an Interim Action ROD to address the ground water contamination. EPA
issued a second UAO in 1993, requiring the PRPs to implement the ground water interim
actions. The 1991 ROD was amended in 1998, to allow the PRP's to perform the interim action
utilizing newer technologies including air stripping and in-well-aeration (IWA). In 1999, the
Phase I and Phase II ground water treatment wells were installed. The Phase II treatment wells
began operating in December 1999, and are constructed utilizing the IWA design. A Phase III
IWA treatment system began operation in November 2002. Under terms of the 2006 CD, Dravo
Corporation is committed to continuing the soil and ground water cleanup actions. Additional
work (i.e., Phase IV) by the PRP is expected to define the extent of the Colorado Avenue OU 1
plume, which has traveled beyond the area of the Phase III treatment system.

The Second Street Subsite is located at the eastern edge of downtown Hastings. EPA completed
an Action Memorandum (AM) for the Second Street subsite in 1995. The removal action
defined by the AM was needed to remove benzene from soils and ground water within the
subsite boundaries. EPA began construction at the subsite in 1996. Both treatment systems
began operation in January 1997, and are currently being operated by the City. Contaminated
vapors are withdrawn from the soils using SVE, and ground water is being treated by an air
stripper followed by liquid phase granular activated carbon. EPA initiated a second removal
action at the Second Street subsite in September 2000. An in-well aeration system was installed
to remove benzene and other volatile contaminants from the ground water. The IWA system
began operation in the summer of 2001. After completion of the RI/FS, an Interim Record of
Decision selecting in-situ treatment combined with extraction and treatment of the ground water
(OU 20) was signed in July 2003. The Interim ROD further requires that treatment systems
installed during the 1996 and 2000 removal actions will continue to operate. The remaining
areas of ground water contamination identified to the east and south are being treated by
injection of an oxygen release chemical to enhance naturally occurring biodegradation of the
contaminants. The first treatment to initiate the in-situ bioremediation activities was completed
in November 2005. EPA is working closely with the Nebraska Department of Environmental
Quality under the terms of a State Superfund Contract completed in 2004. EPA performed
additional soil investigations to identify any remaining contaminant source areas at the subsite
and completed the OU 12 FS in 2006. The Final Record of Decision for OU 12 was signed in
September 2006, and requires that remaining contaminant source areas at the subsite be
excavated and some treated in-situ to mitigate further releases to the ground water. EPA is
preparing the remedial design for these acitivities.

The North Landfill Subsite is located east of the City and north of Highway 6. The City
operated a municipal/industrial landfill from 1962-1964. In 1991, EPA issued a ROD for an
interim remedial action to address both source control and the ground water contamination. In
October 1992, the City and Dutton-Lainson entered into an Administrative Order on Consent
(AOC) to perform the remedial design. The design for the source control operable unit was
completed in 1996, and consisted of improving the landfill cap and restricting public access and

-------
future land use. In the fall of 1998, the PRPs began construction of the landfill improvements.
The landfill improvements were completed in the summer of 1999. The design process for the
ground water operable unit was suspended by EPA while the City and Dutton-Lainson
participate in a removal action for the downgradient ground water operable unit at the
FAR-MAR-CO Subsite. The ground water contamination originating from the FAR-MAR-CO
Subsite has commingled with ground water emanating from the North Landfill Subsite.

Quarterly ground water monitoring has been conducted by the PRPs and was contained in a
December 2002 report to EPA. EPA negotiated agreements with both parties to complete a final
FS for ground water remediation in 2005. The PRPs also conducted quarterly vadose zone
monitoring for 8 quarters to determine if the landfill continues to be a source of VOCs to the
aquifer. The results of this monitoring indicated that the landfill is not currently the major
source of TCE contamination. Additional ground water monitoring wells have been installed
and monitored by the PRPs. Ground water data from these wells suggest that most of the ground
water contamination is from an upgradient source and is disrupting the progress of natural
attenuation of contaminants at the subsite. EPA and the PRPs negotiated a Consent Decree in
2007, to develop the final remedial design at the subsite.

The FAR-MAR-CO Subsite is located east of the North Landfill Subsite. On September 30,
1988, EPA signed a ROD selecting soil vapor extraction (SVE) as the technology to address the
commercial grain fumigant contamination in the soils. In September 1990, Farmland Industries,
Inc., a former owner of the subsite, performed an SVE pilot study to verify the effectiveness of
removing carbon tetrachloride and ethylene dibromide (EDB) from the soils. During the
operation of the SVE pilot, over 1,200 pounds of carbon tetrachloride and EDB were removed
from the soils. In January 1992, Farmland agreed to design a full-scale SVE system. In August
1995, an Explanation of Significant Differences to the ROD was issued to extend the SVE
operation as a measure to mitigate migration of ground water contamination leaving the source
area. Farmland and the current owner of the subsite, Cooperative Producers, Inc., entered into a
Consent Decree which requires that they perform source control using SVE. Farmland began the
full scale operation of the SVE system in July 1997. The SVE attained remediation goals in May
2000, and entered into the SVE-plus phase, which required the system to perform for an
additional two year period, until May 2002. Farmland collected soil vapor samples in November
2002 and May 2003, to determine if any rebounding of the contamination occurred. The SVE
remediation system was decommisioned and restoration activities completed in December 2003.
In 1987, during EPA's investigation of the carbon tetrachloride and EDB contamination at the s
ubsite, a separate area of soil contaminated by 1,1,1-trichloroethane (TCA) was found at the sub
site (Operable Unit No. 11). Pursuant to a December 1989 AOC, HIPCO excavated
approximately 43 cubic yards of soil and transported it to a permitted disposal facility. A ROD
for the TCA Operable Unit was signed in September 1990, in which no further action was
determined necessary to address the TCA contamination. EPA entered into an Administrative
Order on Consent (AOC) with Morrison Enterprises in June 1996, to perform a ground water
removal action. Construction and installation of the ground water extraction system began in
December 1996. Pumping of ground water to control the carbon tetrachloride and EDB plume
began in July 1997, and continues. EPA anticipates that it will take 15 years to restore the
aquifer to MCLs. In 2002, Morrison presented a report documenting the first five years of
operation for EPA's review and approval. EPA evaluated the performance of the system based
upon the information presented in this report. In 2006, Morrison Enterprises completed the FS

-------
for the final response action for the ground water remedy. In 2007, EPA signed a ROD selecting
enhanced in-situ bioremediation, continued extraction and treatment of contaminated ground
water and additional ground water monitoring as the final remedial action. EPA is negotiating
with the PRPs on a Consent Decree to implement the final remedial action at the subsite.

The South Landfill Subsite is located in the southeast section of Hastings. During the 1960's and
1970's, municipal and industrial wastes were disposed at the landfill. EPA began field
investigations in 1994, and confirmed the presence of industrial solvents in the landfill. EPA
developed the Remedial Investigation report to document the investigation. The PRPs
completed the FS under terms of an Administrative Order. EPA completed a ROD for the
subsite in September 2000. The selected remedy for the South Landfill includes upgrading the
landfill cap and monitoring natural attenuation for the ground water. EPA negotiated a CD with
the responsible parties and the work began in late 2004. The landfill cap was installed in 2005,
and a methane investigation was also conducted. A need for periodic methane gas sampling is
anticipated. The PRPs are currently performing ground water investigation activities to support
preparation of the remedial design for the ground water plume.

The Former Naval Ammunition Depot (NAD) is located in eastern Adam and western Clay
Counties and consists of approximately 48,000 acres. The contaminants of concern are volatiles
(VOCs), heavy metals, polycyclic aromatic hydrocarbons (PAHs) and explosives. The Corps of
Engineers (COE), an agent for Department of Defense (DOD), has conducted the following
cleanups. In 1995, the COE completed: a time-critical removal action to excavate two manholes,
a catch basin, piping and contaminated soils, sludges and liquids for Operable Unit No. 8; and a
full-scale pilot system, incorporating air sparging via horizontal and vertical wells (Operable
Unit No. 14). The pilot was successful. Construction of these SVE systems began in October
1996, for Buildings 104 and 135 areas to cleanup the soil contaminated with VOCs. In July
1998, the COE completed an action to address soils contaminated with explosives and PAHs
(Operable Unit No. 4). Major components of the action include excavation of contaminated soils
and placement of low-level soils in an onsite soil repository and incineration of excavated soils
containing high levels of explosives and PAHs. SVE systems were installed to address the
contaminated soil at Building 130, South Disposal Area and Naval Yard Dump. Cleanup
activities on the former NAD have remediated all known surface sources of contamination. SVE
successfully removed SVOCs from the vadose zone soils. The COE completed a remedial
investigation report which addresses other areas of the NAD suspected to be contaminated and
the contaminated ground water beneath the subsite. The COE is currently developing the plan to
address the remediation of the contaminated ground water.

Area-Wide Hastings Site activities have continued to provide assurances of the effectiveness for
remedies being implemented at the City Subsites (i.e., the six non-NAD subsites). In 1996, EPA
completed a Remedial Investigation (RI) report which addresses the area-wide ground water
contamination for the City Subsites. The RI report included a risk assessment prepared by the
Nebraska Department of Health to determine the risks associated with contamination in the
aquifer underneath the City of Hastings. In 2000, the PRPs prepared the Area-Wide FS under
the terms of an Administrative Order. The Area-Wide FS was needed to evaluate site-wide
environmental conditions taking into account the completed and proposed remedial measures
for the various City Subsites. The purpose of the FS was to integrate the information collected at

-------
each subsite into a comprehensive document and evaluate remedies designed to protect potential
receptors from unacceptable risks posed by ground water. In 2001, EPA, in consultation with
NDEQ, signed a ROD for an interim remedial action. The ROD provides for establishing an
institutional control area (ICA), alternate water supply for affected users, well inventory and
ground water monitoring program. The City implemented components of this action, including
establishing the ICA through a City Ordinance, conducting sampling and testing of private wells
in the ICA and preparation of annual ICA reports. EPA and the Area-Wide PRP Group
completed a CD to facilitate full scale implementation of the remedy. The Area-Wide PRP
Group initiated its work efforts in 2004, and completed its first annual ICA ground water report
in early 2005. Monitoring the quality of the ground water and privately owned drinking water
wells is a part of the Site remedy currently being performed by the PRPs. The ICA extends to
areas east of Hastings and the water quality data is useful to track the advancement of the
contaminant plumes. Over the long term, the water quality data will be useful to demonstrate
effectiveness of the subsite remedial actions. In July 2007, EPA completed its Third Five-Year
Review Report for the entire Hastings Site. This report is on Region 7's web site
(www.epa.gov/region07/cleanup/index.htm) under Five-Year Review Reports, FY 2007.

ENVIRONMENTAL PROGRESS

Due to the numerous cleanup actions and the number of contaminated areas and
subsites at the Hastings Ground Water site, the status of cleanup activities varies. The ground
water actions will be long-term. In general, however, the potential for exposure to hazardous
substances in the ground water has been greatly reduced by closing down contaminated wells
while further studies and cleanup activities are being planned and conducted. Further
contamination of the ground water is being prevented by EPA and other parties' efforts to clean
up the sources of contamination.

EPA continues to monitor the work being performed by the PRPs and the quality of the ground
water at the EPA-funded subsite. Private property owners and businesses are notified when
contaminant levels exceed acceptable limits.

EPA, NDEQ and the potentially responsible party group are applying the Superfund process to
determine acceptable actions to manage contamination associated with the Hastings Site.
