Executive Summary
This report presents the remedial investigation (RI) completed by the U.S. Environmental
Protection Agency (EPA) for Operable Unit 1 of the Hamilton/Labree Roads Groundwater
Contamination Superfund Site (Site) in Chehalis, Washington.
The data used to develop the RI were collected during numerous investigations conducted
across the Site between 1993 and 2007. These investigations were conducted by numerous
parties, often for distinct and different purposes. The interpretation of the data may have
varied over time as additional data were collected. While this document attempts to provide a
complete and cohesive RI, it is acknowledged that there may be inconsistencies in the report
at times, and numerous data gaps remain for the RI.
The Site is located near the intersection of North Hamilton Road and Labree Road, west of
Interstate 5 (1-5), about two miles south of the City of Chehalis, Washington. The Site
includes two areas where releases of hazardous wastes are known to have occurred: Operable
Unit 1, which is hereafter referred to as the Hamilton Road Impact Area (HRIA), and the S.C.
Breen Construction Company (Breen) Property. The Site also contains an area where a
release is likely to have occurred called, for purposes of this RI report, the Thurman Berwick
Creek Area. Contaminated groundwater plumes that originate from these areas extend
downgradient and west of Labree Road. To distinguish these areas from Operable Unit 1, the
Breen Property, Thurman Berwick Creek Area, and downgradient areas of the HRIA and
Breen Property compose Operable Unit 2.
The HRIA includes a property containing two large commercial buildings that are occupied
by United Rentals, grassy open land on the west, parking for an RV outlet center on the
south, and to the east, across North Hamilton Road, is Berwick Creek and the grassy buffer
for 1-5. The Breen Property, located to the northwest of the HRIA, is occupied by five large
commercial buildings, three of which (Buildings A, B, C) are occupied by Breen
Construction Company, and the remaining two by a livestock auction house. The Thurman
Berwick Creek Area occupies the southeast corner of the intersection of North Hamilton
Road and Labree Road, south of the Breen Property and is bisected by Berwick Creek. The
remainder of the Site area to the west, northwest, and south is primarily farmland with some
residences and light commercial developments.
This report presents an interpretation of groundwater, soil, surface water, creek bed
sediment/soil, and other data collected to assess the nature and extent of contamination,
contaminant fate and transport, and potential risks to human health and the environment
associated with contaminated media across the Site with a focus on the HRIA that comprises
Operable Unit 1.

Executive Summary »
Operable Unit 2 has not yet been fully characterized. This report, however, includes information on the
investigations conducted and the preliminary data results obtained to date at these areas to better
understand Site-wide groundwater contamination.
Historical Investigations
After the discovery of tetrachloroethene (PCE) in private wells in 1993, the Washington State
Department of Ecology (Ecology) performed several investigations to find the source of the
contamination. Both the HRIA and Breen Property were identified as sources during these
investigations. EPA took over the investigation work in July 2000, when the Site was added to the EPA
National Priorities List (NPL).
In 2003, EPA began additional investigations to better define the extent of soil and groundwater
contamination, including defining the extent of dense non-aqueous phase liquid (DNAPL) in the
Berwick Creek bed and the shallow aquifer related to a potential release or spill into Berwick Creek.
Around the same time, Breen initiated Phase IIRI sampling to better define the nature and extent of
contamination on and downgradient of the Breen Property.
In July 2007, EPA conducted supplemental groundwater and surface water sampling across the Site,
focusing on the areas downgradient of the HRIA and Breen Property. Sampling included private wells
along Rice Road that had not been previously sampled and private wells that had historically contained
PCE. In addition, in November 2007, EPA conducted air sampling in and around private residences and
commercial buildings across the Site. The resulting data were used to assess whether volatilization of
contaminants from the shallow aquifer was impacting indoor and outdoor air.
Nature and Extent of Contamination
Both the HRIA and the Breen Property have been identified as sources of contaminants of potential
concern (COPCs) in shallow groundwater beneath the Site. A third potential source appears to be
located within or upgradient of the Thurman Berwick Creek Area. This contaminated groundwater
occurs in an aquifer that extends from roughly 5 feet to approximately 50 feet below the ground surface
(bgs). The shallow aquifer is used as a drinking water source for area residences not on the City of
Chehalis water system.
The COPCs are primarily PCE and its daughter or degradation products trichloroethene (TCE), cis-1,2-
dichloroethene (cis-l,2-DCE), and vinyl chloride, and the chemicals tetrahydrofuran and methylene
chloride. Total petroleum hydrocarbons (TPH) are also being considered as presumptive COPCs until
proven otherwise.
The primary contaminant at the HRIA is the result of an apparent spill or dumping of PCE into Berwick
Creek in the vicinity of sampling location MW-602, located east of the main United Rentals Building.
The spill is estimated to have occurred sometime before 1990. The data point strongly to a single
release at this location, but multiple releases may have occurred along a 400-foot reach of Berwick
Creek. The estimated volume of the release is between 100 and 700 gallons. The contaminant at the
HRIA is PCE, and there is no evidence of the PCE being mixed with any other contaminant. Some
breakdown compounds of PCE are present, including TCE and cis-l,2-DCE, but at much lower
concentrations than PCE and with a much lower frequency of detection. PCE has contaminated a silt
layer in the bed of the creek and the soil and groundwater of the shallow aquifer.

-------
Executive Summary »
The groundwater contamination at the Breen Property appears to be from multiple sources/releases
related to site operations between the early 1960s and early 1990s. One source (the former location of
buried drums beneath Building B) was remediated in 1999, and two other sources (a former wash-down
pad and an area between Building C and the Torpedo Tube) appear to exist on the Breen Property.
The results of groundwater sampling conducted in the areas downgradient of the HRIA and south of the
Breen Property indicate the presence of a potential source within or upgradient of the Thurman Berwick
Creek Area. The location of this potential source is currently unknown.
Based on the most recent groundwater sampling event conducted in summer 2007, both the HRIA and
the Breen Property appear to be active sources as concentrations have not significantly declined since
2003. The groundwater plume originating from the HRIA appears to be the younger and the more
concentrated of the two plumes and has migrated at least 2,000 feet from its source, assuming the HRIA
source is not much older than 1990. The plume from the Breen Property appears to be older and less
concentrated based on historic information regarding operations at the site and on investigation results.
Although the full extent of the Site-wide plume is not currently known, it appears to have migrated a
minimum of 3,000 feet downgradient from the Breen Property to the west-northwest of Labree Road.
Based on the groundwater modeling completed for the Site, the maximum length of the plume
emanating from the HRIA is approximately 2,000 feet, or approximately 500 feet west of Labree Road,
assuming the release into Berwick Creek did not occur much before 1990 based on the observed extent
of the HRIA plume in 1993. If so, the majority of the downgradient groundwater plume west of Labree
Road most likely originated from the Breen Property and the Thurman Berwick Creek Area. Moreover,
a north-south zone east of where North Hamilton Road crosses Berwick Creek appears to act as a PCE
"bottleneck," where PCE transport in the upper zone of the shallow aquifer to the Breen Property and
the Thurman Berwick Creek Area is limited. Within this "bottleneck" area, the upper 20 feet of the
shallow aquifer has very little PCE contamination. Therefore, the PCE contamination in the upper zone
of the shallow aquifer west of this north-south "bottleneck" zone (including the Breen Property and the
Thurman Berwick Creek Area) could not have come from the HRIA.
PCE concentrations in the lower zone of the shallow aquifer in the Thurman Berwick Creek Area
reflect mixing between deeper groundwater contamination from the Breen Property or upgradient
Berwick Creek sources and deeper groundwater contamination from the HRIA. In the lower zone
downgradient of the "bottleneck," the contribution from the HRIA appears to be limited to
approximately 1,000 micrograms per liter (j^ig/L) based on PCE isoconcentrations maps developed for
the Site. Regardless of the age of the HRIA source, these apparent constraints on PCE migration
suggest that in the area downgradient of Labree Road, approximately 25 to 30 percent of contamination
is from the HRIA source zone. However, a full mass flux/discharge evaluation would need to be
conducted within the upper and lower zones of the shallow aquifer to determine the actual contribution
from the HRIA.
Currently, the extent of the PCE groundwater plume downgradient of the Breen Property and the
Thurman Berwick Creek Area west of Labree Road is unknown. In addition, the plume edges in the
downgradient area west of Labree Road have not been adequately established, particularly on the
northeast edge parallel to 1-5.

Executive Summary »
Baseline Risk Assessment
The human health risk assessment concluded that if current groundwater concentrations of volatile
organic compounds (VOCs), particularly PCE, persist and groundwater is used as a drinking water
source in the future, the health of on-site workers or downgradient residents may be adversely affected.
However, the commercial and private properties in and near the known area of the contaminated
groundwater plume are connected to a municipal water system. There are no drinking water wells in use
within the currently known extent of the plume, and so EPA is reasonably confident that current human
populations are not drinking contaminated water. If the contaminated groundwater plume is allowed to
persist, or if the plume has migrated in an unanticipated direction or to a greater extent than anticipated,
residences downgradient of the municipal water supply line could be affected in the future. At three
subareas evaluated in the HRIA (the area along North Hamilton Road plus the area between the road
and Berwick Creek north of where the road bends to the west, the core United Rentals area, and the
fringe United Rentals area), potentially elevated noncancer and cancer risks are estimated for
construction or utility workers that may work in a trench for an extended period. The COPC
concentrations in trench air are particularly uncertain because they were estimated from groundwater
concentrations, but the risk estimates suggest that precautions should be taken if trenching occurs in
these areas in the future. Estimated risks from the volatilization of contaminants in groundwater to
indoor air are below the risk threshold level at the HRIA and the Breen Property, as well as
downgradient residences. However, the indoor air inhalation risk estimates are based on one round of
indoor sampling; additional indoor air sampling is necessary to refine the indoor air inhalation risk
estimates. Recreational activities at Berwick Creek are anticipated to be of minimal concern if
conducted away from the primary PCE spill source at the HRIA.
The overall results of the ecological risk assessment indicate that current contaminant concentrations of
PCE in subsurface soils and sediment associated with the HRIA spill area may represent a potential for
elevated risks to organisms. However, risks to ecological receptors are ultimately considered to be
minimal because (1) highly conservative exposure estimates were utilized in the baseline risk
assessment (BRA) and (2) the HRIA spill area is generally confined to a small area within Berwick
Creek, although PCE (but not the other COPCs) was detected in Dillenbaugh Creek surface water along
the northeastern edge of the plume.
Overall, PCE and associated VOC risks are localized in groundwater, soils, and sediment. Domestic use
of groundwater is the primary concern at the Site (i.e., HRIA and Breen Property, and downgradient
areas) and institutional controls (i.e., use of municipal water systems rather than groundwater sources
and restricted access to the HRIA and Breen Property) will minimize exposure to contaminants
associated with the HRIA and the Breen Property. The potential inhalation risks from VOCs,
particularly PCE and TCE, in trenches at select subareas of the HRIA are also of concern, and
institutional controls (e.g., requirements for personal protection) should be considered to reduce
exposures via this route (or trench air concentrations could be empirically determined to refine the risk
estimates before workers spend time in a trench).
Due to the uncertainties and limitations related to data gaps for soil, groundwater, and surface water
analysis, additional sampling and analysis will be needed across the Site. This is especially true for
contaminated groundwater in the upper portion of the shallow aquifer and the potential risks from vapor
intrusion.

Executive Summary »
Summary and Conclusions
Soil
Soil depths have been divided into three categories for purposes of delineating PCE contamination:
surface, near surface and subsurface. In general, surface soils at this Site are defined as 0 to 5 feet bgs
and near surface soil at 5 to 10 feet bgs. Subsurface soils exist at depths greater than 10 feet and are
typically below the silt cap/shallow aquifer contact.
Currently, the only identified surface/near surface soil source of PCE to groundwater is Berwick Creek
bed sediment/soil in the HRIA. Only minor surface soil contamination has been identified at the Breen
Property and in downgradient areas. The highest PCE concentration was detected in subsurface soil
beneath the apparent PCE release in Berwick Creek within the HRIA at high concentrations indicative
of PCE DNAPL Much lower PCE concentrations have been detected in subsurface soils at the Breen
Property. Additional investigations are required at the Breen Property to identify the source of
groundwater contamination, which may include unidentified soil sources.
No surface or near surface soil samples from the Thurman Berwick Creek Area or downgradient areas j
west of Labree Road had detectable PCE. However, the only samples that have been collected were )
from shallow (8-foot maximum) borings along road right-of-ways, not in areas where disposal may
have occurred.
Available subsurface soil sampling data for the Thurman Berwick Creek Area and downgradient areas
west of Labree Road are limited. PCE was detected at four locations in the Thurman Berwick Creek
Area with a maximum of 1.3 milligrams per kilogram (mg/kg). Soil data are available from one boring
location west of Labree Road (MW-25); a maximum of 0.13 mg/kg PCE was detected in a sample
collected at 40 feet bgs. PCE was not detected in shallower samples.
Groundwater
At the HRIA, PCE in groundwater is attributed to a source where PCE was spilled or released to
Berwick Creek, an area referrred to as the Southeastern Hot Spot. Based on high PCE concentrations up
to 2,720,000 (ig/L, DNAPL is inferred to exist in the shallow aquifer beneath the apparent release
location to a depth of approximately 35 feet. Additional investigations will be required to identify
remaining sources of shallow aquifer PCE contamination at the Breen Property and the downgradient
extent of the associated groundwater plume.
In the Thurman Berwick Creek Area, PCE greater than 1,000 (ig/L was detected in groundwater
samples collected from private well PW-9 and in shallow groundwater samples collected from several
monitoring wells located downgradient of, and adjacent to, Berwick Creek. Because PCE was detected
in shallow groundwater, a local source of contamination is probable.
Currently, the extent of the PCE groundwater plume downgradient of the Breen Property and the
Thurman Berwick Creek Area west of Labree Road is unknown. In addition, the plume edges in the
downgradient area west of Labree Road have not been fully characterized, particularly on the northeast
edge parallel to 1-5.

Executive Summary »
Surface Water
Surface water data indicate that concentrations of PCE in surface water do not pose a risk to aquatic
receptors within Berwick Creek or Dillenbaugh Creek. The source of the PCE in surface water samples
collected at several stations in Berwick Creek may be residual contamination that is dissolving from
PCE entrained in the creek bed sediment/soil.
No surface water samples have been collected in Berwick Creek in the northern portion of the HRIA.
High PCE concentrations have been detected in groundwater near an area referred to as the
Northwestern Hot Spot. It is unknown if contaminated groundwater related to these areas potentially
discharges to surface water.
Surface water samples collected in Dillenbaugh Creek indicate that PCE is present in surface water.
The concentrations are most likely related to discharge of PCE-contaminated groundwater to
Dillenbaugh Creek. The extent of the groundwater plume is unknown, and higher concentrations may
be discharging to Dillenbaugh Creek farther downstream. Additional analytical data are necessary to
adequately characterize impacts to surface water in the downgradient areas. |
Creek Bed Sediment/Soil
Creek bed sediment/soil contamination appears to be primarily confined to the HRIA and an area
immediately downstream of this area. PCE DNAPL has been identified in a silt layer beneath the
Berwick Creek bed. The residual DNAPL is providing a continuing source of dissolved PCE to
groundwater.
No creek bed sediment/soil samples have been collected from Berwick Creek in the northern portion of
the HRIA. Based on soil and groundwater data for monitoring wells installed in the vicinity, a separate
potential creek source is suspected.
As stated previously, PCE concentrations greater than 1,000 j^ig/L were detected in groundwater
samples collected from private well PW-9 and in shallow groundwater samples collected from several
monitoring wells in the Thurman Berwick Creek Area downgradient of, and adjacent to, Berwick
Creek. A local source of contamination such as a release to Berwick Creek is likely. Additional
sampling of sediment/soil in Berwick Creek in this area is necessary to assess if a release has occurred.
Indoor and Ambient Air Quality
Air sampling data from the Site showed low levels of PCE in the majority of the residential,
commercial, and ambient locations. However, the estimated risks from the volatilization of
contaminants in groundwater to indoor air are below the risk threshold level at the HRIA and Breen
Property, as well as at downgradient residences.
Overall, the evaluation of vapor intrusion is limited, and confidence in conclusions of the assessment is
low. Additional data would be necessary to provide a more useful evaluation of this pathway. Based on
the results of investigations to assess the downgradient extent of groundwater contamination, additional
air sampling and assessment of vapor intrusion may also be required at residences along Rice Road and
other downgradient locations.

Executive Summary »
Data Limitations
A full formal RI investigation has not been completed at the Site. Instead, the data used to develop this
RI report were collected during numerous investigations conducted at the Site between 1993 and 2007.
In several cases, conclusions developed by the entity that collected and interpreted the original data
were used to complete this RI.
Based on review of historical data, soil samples collected for VOC analysis do not appear to have been
preserved using the protocols specified under EPA Method 5035A. The primary goal of this VOC
collection and preservation technique is to minimize the direct volatilization of contaminants in soil to
the atmosphere. Since EPA Method 5035A does not appear to have been used during soil sample
collection, VOC analytical results may be biased low, especially for samples collected from the
gravelly materials that comprise the shallow aquifer.
A large body of groundwater data exists for the Site, but it is unevenly distributed, both horizontally
and vertically. For example, little data are available in the plume downgradient of Labree Road.
Vertically, the data come from a wide mix of screened-interval lengths, including: 1) 1-foot intervals in
temporary borings, 2) monitoring wells with conventional 10-foot screens, 3) monitoring wells
screened across the entire shallow aquifer, and 4) private wells of unknown construction. Consequently,
data interpretation requires subjective judgments as to which data should be honored, emphasized, or
disregarded.
The most recent groundwater monitoring and sampling data collected at the Site were used to assess
groundwater flow and plume migration. The last extensive groundwater sampling occurred at the Site in
November 2003. These 2003 groundwater data were supplemented with the results of a limited
groundwater sampling event conducted in July 2007 to assess the current PCE plume movement
throughout the Site.
Creek channel samples were collected by Farallon south of the Breen Property. The samples were
collected from the creek bed at approximately 1 foot bgs. Based on available sample collection
information, it is unclear whether these samples were collected from sediment accumulations in the
creek channel or if the samples were collected from the silt layer that composes the creek bottom.
Based on the creek bed sample results for the HRIA, PCE was mainly detected within the silt layer.
Creek samples collected south of the Breen Property may not represent the actual PCE concentrations
in the Berwick Creek bed near the Breen Property.
Limited data regarding groundwater and surface water interaction were available downgradient of the
Breen Property. Surface water data were collected in July 2007 from Dillenbaugh Creek but were
limited to two samples.
Recommendations for Future Action
Recommendations for future action at the Site include the following:
Site-Wide
Conduct aquifer testing in the area downgradient and west of Labree Road and downgradient of
the United Rentals facility to better define Site-wide hydraulic conductivity.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
xv
-------
Executive Summary »
Evaluate horizontal and vertical hydraulic gradients Site-wide in and between the upper and
lower zones of the shallow aquifer and assess seasonal gradient shifts in direction by collecting
comprehensive gradient data at least quarterly for one year.
Evaluate depth-discrete variations in hydraulic conductivities and preferential pathways
associated with relatively higher-conductivity stratigraphic layers within the shallow aquifer by
conducting aquifer testing within temporary boreholes and completed wells screened at discrete
depths within the aquifer and include findings in numeric and 3D EVS model.
Collect soil core samples for analysis of porosity, density, and grain size to better define Site-
wide aquifer characteristics.
Complete additional assessment and mapping of the Site-wide vertical distribution of PCE in
groundwater. In particular, contaminant characterization of the lower zone of the shallow
aquifer between the United Rentals facility and the "bottleneck" is needed, as well as vertical
and horizontal plume transects from Labree Road to the end of the plume.
¦ Evaluate the relative contribution of the HRIA, Breen Property and/or Thurman Berwick Creek
Area contaminant sources on contaminant mass loading to the Site-wide contaminant plume by
evaluating mass discharge of contaminants from proposed transects.
Sound the depth of private wells with no logs that are located within the plume.
Delineate the impacts of contamination in the deep aquifer within the HRIA, Breen Property
and Thurman Berwick Creek Areas by installing additional, deep monitoring wells. These wells
would need to be carefully installed using best practices to prevent contamination from the
shallow aquifer from migrating to the deep aquifer during and after well construction.
Conduct a stable isotope study, including analysis of tentatively identified compounds (TICs),
to distinguish between PCE from the HRIA, the Breen Property, and the Thurman Berwick
Creek Area.
Update Site-wide EVS modeling using newly acquired Site chemical and physical data
discussed in other sections of this RI report, . Update three-dimensional fate and transport
modeling using the newly collected aquifer parameters.
Install shallow piezometers within the stream bed along Berwick and Dillenbaugh Creeks to
measure head differences between the surface water of the creek and the groundwater within
the bed/or slightly below the bed of the creek in order to determine where gaining and losing
reaches of the creek exist and their influence on contaminant fate and transport.
Conduct additional indoor and ambient air sampling following completion of the remedial
action at the HRIA.
HRIA
Collect surface water samples in the section of Berwick Creek between approximately MW-R4
and MW-33. No surface water sampling appears to have been conducted in this length of
Berwick Creek.

Conduct one to two north-south transects between MW-3 and MW-22/23 to assess contaminant |
mass discharge at the outlet of the HRIA source area and the inlet of the interface with the J
Breen/Thurman Berwick Creek source(s). Groundwater samples would be collected at four |
different intervals in each boring: a shallow interval (upper 5 feet of the aquifer), from
approximately 15-25 feet bgs, from approximately 30 to 40 feet bgs, and a deep sample from
approximately 40 feet bgs to the bottom of the aquifer (typically around 50 feet bgs).

of MW-24 to RS-24.
Install east-west centerline borings in both the northern and southern plume lobes to fill in
between north-south transects.
Install a transect extending east and west from the HRIA source area containing DNAPL
(Southeastern Hot Spot) to the Thurman Berwick Creek area. Collect lithologic information
and aquifer parameters. Groundwater sampling would be completed at the same intervals as
discussed for the two north-south transects between MW-3 and MW-22/23. Use information
from this transect to prepare a cross-section identifying conditions from the HRIA, through the
"bottleneck", and to the Thurman Berwick Creek Area.
Breen Property
Conduct a geophysical investigation in areas not previously investigated to attempt to locate
potential sources, such as additional buried drums.
Conduct a subsurface investigation in areas identified as potential sources and in areas
containing geophysical anomalies that were not previously evaluated. Groundwater and soil
samples would be collected at four different intervals in each boring: a shallow interval (upper
5 feet of the aquifer), from approximately 15-25 feet bgs, from approximately 30 to 40 feet bgs,
and a deep sample from approximately 40 feet bgs to the bottom of the aquifer (typically
around 50 feet bgs). Analysis would include VOCs, petroleum hydrocarbons, and metals.
Install additional monitoring wells in areas identified by the subsurface investigation to better
assess the lateral and vertical extent of the groundwater plume and its migration.

Executive Summary »
Install additional monitoring wells in the southeastern and central portions of the property to
evaluate a potential northern migration pathway from the HRIA.
Complete a round of groundwater sampling and analysis (including VOCs, petroleum
hydrocarbons, metals, field monitored parameters, and general chemistry) that would include
newly installed wells and existing wells to obtain a current snapshot of the groundwater plume
at the Breen Property.
Soil samples collected from borings need to be handled and preserved per EPA Method 5035A
and analyzed for VOCs and petroleum hydrocarbons.
Thurman Berwick Creek Area

Labree Road and MW-25 to better assess the groundwater plume and its migration.
Install monitoring wells downgradient of MW-25 along the approximate plume axis, based on a
series of boring transects. Proposed well locations should include the area between MW-25 and
the suspected leading edge of the plume, at or near the leading edge of the plume, and between
the leading edge and at a downgradient point(s) where PCE is undetectable. Groundwater
samples would be collected at four different intervals in each boring.
Install subsurface borings to collect soil and groundwater samples between RS-47 and 1-5 to
assess the extent of the groundwater plume from the Breen Property.
Install two subsurface borings and collect soil and groundwater samples in the high-uncertainty
area identified in the EVS modeling to the south of RS-49 to assess the extent of the apparent
plume from the Thurman Berwick Creek Area and to better assess the portion of the plume
upgradient of PW-21.
Collect surface water samples in Dillenbaugh and Berwick Creeks between Labree Road and
MW-28 to assess PCE concentrations. In addition, collect groundwater samples adjacent to the
surface water sample locations along Dillenbaugh Creek to evaluate the concentrations of
groundwater potentially being discharged.

Section 1
Introduction
This report presents the results of a remedial investigation (RI) completed by the U.S.
Environmental Protection Agency (EPA) for Operable Unit (OU) 1 of the Hamilton/Labree
Roads Groundwater Contamination Superfund Site in Chehalis, Washington. The RI was
completed under the EPA Region 10 Architect and Engineering Services (Small Business)
Contract No. 68-S7-03-04. This RI report was prepared in accordance with the Guidance for
Conducting Remedial Investigations and Feasibility Studies under the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA) [Interim Final,
October 1988] (EPA 1988).
The Hamilton/Labree Roads Groundwater Contamination Superfund Site (the Site) consists
of two OUs referred to as OU 1 and OU2. OU 1 is also known as the Hamilton Road Impact
Area (HRIA). OU2 consists of the S.C. Breen Construction Company (Breen) Property, the
Thurman Berwick Creek Area, and all other associated geographic areas where
tetrachloroethene (PCE) and related chemicals have been found in groundwater. The Site
location is shown on Figure 1-1 and described further in Section 1.3.1.
A full formal RI investigation has not been completed at the site. Instead, this RI report
represents a compilation of numerous published documents and data not previously presented
in reports, which were generated by a variety of consultants and EPA between 1993 and
2007. Investigations were conducted on behalf of EPA, the Washington State Department of
Ecology (Ecology) and Breen over the years. While this document attempts to provide a
complete and cohesive RI, numerous challenges were encountered during compilation of this
RI, including:
Varying purposes of the different phases of investigations
Varying investigation methods utilized over the years
Improvements in various technologies (i.e., soil sample collection methods)
Loss of data (e.g., missing sample location information, missing analytical data)
Transcription errors (e.g., analytical data, survey data, etc.)
Unsurveyed exploration locations
Changes in personnel working on the project over time
Differing opinions by the various consultants and agencies working on the project
¦ The complexity of the Site
It is therefore acknowledged that there may be inconsistencies in the report and numerous
data gaps remain for the RI.

This section presents background information, including a description of the Site and its history.
1.3.1 Site Description
The Site is located near the intersection of North Hamilton Road and Labree Road, west of Interstate 5
(1-5), about two miles south of the City of Chehalis, Washington (Figure 1-1). The Site includes two
areas where releases of hazardous wastes are known to have occurred: OU1, known as the HRIA, and
the Breen Property. The Site also contains an area where a release is likely to have occurred called, for
purposes of this RI report, the Thurman Berwick Creek Area (Figure 1-1). Contaminated groundwater
plumes originating from these areas extend downgradient and west of Labree Road. The Breen
Property, the Thurman Berwick Creek Area, and the remaining extent of the contaminant plume outside
of these specifically named properties comprise OU2.
The boundary between the City of Chehalis and unincorporated Lewis County bisects the Site roughly
north to south along the western side of Labree Road. The HRIA, the Breen Property east of Labree
Road, and the Thurman Berwick Creek Area are within the city limits of Chehalis. The entire portion of
the Site within the City of Chehalis is zoned for commercial use. The portion of the Site located in
Lewis County west of Labree Road is zoned as rural development district and agricultural resource
lands. Land uses include agricultural uses (predominately dairy) and residential use (Farallon 2003).
The Site is located within the Newaukum River Valley and has relatively flat topography. Berwick
Creek traverses the Site from southeast to northwest and merges with Dillenbaugh Creek northwest of
the Breen Property. Overall, the Site slopes downward toward the northwest. Groundwater and surface
water flow are generally northwest along the Newaukum River Valley towards the Chehalis River
(URS 2004).
1.3.1.1 Operable Unit 1 - HRIA
The HRIA is located at the most upgradient portion of the Site and is approximately 10 acres in size
(Figure 1-2). It is crossed from northwest to southeast by North Hamilton Road and Berwick Creek.
The portion of the HRIA located between North Hamilton Road and 1-5 consists of grassy open land
that includes Berwick Creek (which flows northwest), overhead power lines, and a wire field fence that
prevent access to 1-5. Two unnamed ditches pass underneath 1-5 and discharge to Berwick Creek within
the HRIA.
The portion of the HRIA west of North Hamilton Road includes the United Rentals Property. The
property is level with mixed gravel, asphalt, and concrete surfaces and contains two buildings: the main

building, and the maintenance and paint shop building. An easement containing buried utilities and a
stormwater conveyance system is located between the United Rentals Property and North Hamilton
Road.
1.3.1.2 Operable Unit 2 - Breen Property
The Breen Property is located northwest of the HRIA and is approximately 11 acres in size
(Figure 1-2). The Breen Property, originally one tax parcel, was subdivided and now consists of two
separate tax parcels that are currently owned by two different entities. The western portion of the Breen
Property is owned by the S.C. Breen Construction Company and consists of approximately 6.5 acres
containing three wood-framed, steel-clad buildings with concrete floors. The first building, identified
as Building A is located at the northern end of the parcel. The second building, identified as Building
B, is located southeast of Building A. The third building, Building C, is located on the southern end of
the parcel and is mostly unoccupied. A concrete wash-down pad approximately 24 feet by 38 feet is
located southeast of Building C. Bulldog Trailers currently operates out of Building A. Building B is
leased by another company.
The S.C. Breen Construction Company sold the eastern portion of its property to the Chehalis Livestock J
Market in 1992 (Farallon 2003). This parcel is primarily used as a cattle auction facility. The parcel is |
approximately 4.5 acres in size and contains a building that houses an arena, a cafe, and offices, plus
outside cattle pens (Livestock Auction Building). A smaller wood-framed building with a dirt floor is
located along the southern boundary (Livestock Shed). This building is primarily used to hold calves
prior to auction. The remainder of this parcel consists of an unpaved parking area. Berwick Creek
extends along the southern property boundary.
1.3.1.3 Operable Unit 2 - Thurman Berwick Creek Area
The Thurman Berwick Creek Area is located in the southeast corner of the intersection of North
Hamilton Road and Labree Road, west and downgradient of the HRIA and south of the Breen Property.
The Thurman Berwick Creek Area is divided by Berwick Creek into two portions: the northwest
portion currently contains a residential structure, and the southeast portion is undeveloped land.
1.3.1.4 Operable Unit 2 - Downgradient Areas West of Labree Road
This portion of the Site includes the remaining area within the groundwater PCE plume footprint that is
downgradient of the HRIA, the Breen Property, and the Thurman Berwick Creek Area west of Labree
Road (Figure 1-2). Most of the current land use in this area is farmland, but residential and light
commercial uses also occur.
1.3.2 Operational History
1.3.2.1 Operable Unit 1 - HRIA
The United Rentals Property forms the largest portion of the HRIA. In 1988, Carl Watson purchased
the United Rentals Property, which was a swampy hayfield containing a few old car bodies and empty
barrels. The property was graded flat and a layer of fly ash and approximately 90 truckloads of rocks
were imported to build up the footprint for the subsequent buildings. The main building was
constructed during the winter of 1989/1990.
The property has changed occupants and ownership numerous times since the late 1980s. Beginning in
June 1990, a transmission rebuilding company operated at the property under the name Westside

-------
Section 1 • Introduction •
Trucking Company. In 1991, Westside Trucking Company changed its name to Gear Box, Inc. and
operated under that name until October 1992, when the business closed.
The property was sold on May 20, 1993, to E.G.W. Machinery, Inc., the owner of High Reach, Inc.
High Reach, Inc. rented and serviced specialized aerial construction equipment. A second building,
known as the paint facility, was constructed on this property in 1993.
In 1998, High Reach, Inc. was purchased by United Rentals Northwest, Inc. At this location, United
Rentals ran a rental and repair service for a variety of construction equipment, as well as operating a
small business that painted heavy equipment until 2009, after which the property was vacated. As of
the date of this RI, the property is vacant.
1.3.2.2 Operable Unit 2 - Breen Property
The S.C. Breen Construction Company purchased the property (both of the current tax parcels) in the
early 1950s. The property was used for agricultural purposes prior to development. Building C was
built in 1962 to serve as the S.C. Breen Construction Company's shop and office. A second building
was used as the Breen Surplus store beginning in the mid-1960s. Breen Surplus bought and sold a
variety of equipment, tools, paints, thinners, and solvents. The rest of the property was used to store
construction equipment and materials. Based on a review of aerial photographs, the wash-down pad
appears to have been constructed between 1966 and 1969. According to Farallon (2003), a shop
building was located adjacent to the wash-down pad until between 1993 and 1999.
By the early 1970s, most of the Breen Property had been cleared of vegetation. A large warehouse
(Building A) was constructed in 1972 on the north end of the property. In about 1983, another
warehouse (Building B) was built on the Breen Property southeast of the 1972 warehouse. In 1995,
Bulldog Trailers opened operations on this property using both the 1972 (Building A) and 1983
(Building B) warehouses. Bulldog Trailers used Building B until 1999 when interim remedial actions
were conducted to remove drums from under the building. Bulldog Trailers now operates out of
Building A, and Building B is leased by another company.
In 1992, the S.C. Breen Construction Company sold the eastern parcel to the Chehalis Livestock
Market. In 1998, the new owners started conducting quarterly farm equipment sales. Currently, the
property is used primarily as a cattle auction house.
1.3.3 Regulatory History
1.3.3.1 Site Discovery
Contamination was first identified at the Site in late 1993/early 1994 when the Washington State
Department of Health (WDOH) sampled 18 private water-supply wells in the area as part of a routine
sampling program. PCE was detected in 6 of the 18 water-supply wells. These 6 wells were screened in
the shallow aquifer and contained PCE ranging from 3.3 micrograms per liter (j^ig/L) to 2,165 (ig/L
(Ecology 1999a). The drinking water maximum contaminant level (MCL) for PCE, as promulgated by
EPA, is 5 (ig/L. Lewis County Public Services informed affected well owners of the sampling results
and advised them to obtain alternative sources of drinking water. Ecology began supplying water for
drinking, cooking, and bathing purposes to affected well owners. In 1996, WDOH resampled 5 of the 6
PCE-contaminated water supply wells and found that concentrations had increased slightly from those
measured in 1993 and 1994. EPA took over the responsibility for supplying bottled water to affected
residences in July 2001.

Section 1 • Introduction •
1.3.3.2 Breen Property Drums and Drum Removal Activity
In 1996, Ecology learned from a confidential source that drums containing solvents might have been
buried on the Breen Property. Ecology initiated an investigation that included a geophysical survey by
Geo-Recon International (Geo-Recon 1996) and a subsurface investigation by Science Applications
International Corporation (SAIC). Between October 1997 and July 1998, Ecology performed quarterly
sampling of monitoring wells installed by SAIC and some private water-supply wells. In spring 1998,
Ecology contracted Transglobal Environmental Geosciences (TEG) Northwest, Inc. to conduct an
additional subsurface investigation.
In August 1999, Breen entered into an Agreed Order with Ecology and contracted for an additional
investigation on the Breen Property. This investigation included a geophysical survey by Northwest
Geophysical Associates in August 1999 and additional subsurface investigation by GeoEngineers, Inc.
In September 1999, 70 drums and a number of pails and cans were removed from beneath Building B
on the Breen Property. All of the drums contained a black viscous product (sludge) and water, as
groundwater had seeped into the leaking drums. PCE and several of its degradation products, including |
|
trichloroethene (TCE) and cis-l,2-dichloroethene (cis-l,2-DCE), were detected in the contents of some |
drums and in water sampled from the excavations during the drum removal (GeoEngineers 2001). The |
drum removal remedial effort is discussed in more detail in Section 2.6.
1.3.3.3 Discovery of HRIA Source Area
A second source of contamination was identified in the area between North Hamilton Road and 1-5
around Berwick Creek during the investigation conducted by TEG for Ecology in the spring of 1998.
TEG advanced direct push (i.e., Stratoprobe™) borings across the Site and collected groundwater
samples. The highest concentration of PCE (60,000 (ig/L) was detected in a boring advanced between
Berwick Creek and North Hamilton Road approximately 40 feet east of the United Rentals property.
PCE concentrations in groundwater sampled from adjacent borings ranged from 22,000 (ig/L to 57,000
(ig/L (Ecology 1999a), indicating a second source area at the Site.
1.3.3.4 Listing of Site
On July 27, 2000, the Site was added to the EPA National Priorities List (NPL).
On October 31, 2001, an Administrative Order on Consent (AOC) was signed between EPA and Breen
(EPA 2001). In accordance with the AOC, Breen (through their consultant, Farallon Consulting, L.L.C.
[Farallon]) initiated Phase I RI activities in July 2002 under EPA oversight to investigate the COPCs in
the shallow aquifer at the Breen Property and in the Thurman Berwick Creek Area.
1.3.3.5 Expansion of Municipal Water Supply Line to Impacted Properties
In 2000, the EPA Superfund Technical Assistance and Response Team (START) contractor, Ecology
and Environment, Inc. (E&E), began a phased removal assessment, which included installing soil
borings and new groundwater monitoring wells and collecting subsurface soil and groundwater samples
in and near the HRIA to evaluate the extent of impacts to private water-supply systems. The assessment
resulted in the expansion of the City of Chehalis municipal water-supply system.
In November 2002, E&E completed the installation of the public water supply line on behalf of EPA
and the City of Chehalis (E&E 2003). A total of 18 properties (15 residential and 3 commercial) were
connected. A property was selected for connection to the City's public water-supply system if it met
one of the criteria listed below.

The private well that provided potable water to the residents or workers at the property
contained detectable concentrations of PCE.
Based on the projected 5-year migration of the PCE plume, the property had a future potential
to be affected by PCE-contaminated groundwater.
The location of the water supply line and properties connected to the line are shown in Figure 1-3.

Section 2
Previous Environmental Investigations
Numerous investigations have been conducted across the Site from 1993 to 2010 by a number
of parties to determine the extent of contamination and its potential impacts. This section
provides a summary of activities for each investigation and the resulting data that were
utilized to develop this RI. The investigation summaries are provided in chronological order.
A history of all investigations conducted at the Site with key findings is summarized in
Table 2-1.
Site-wide COPCs are PCE and its daughter/degradation products (TCE, cis-1,2- DCE, and
vinyl chloride), and the chemicals tetrahydrofuran and methylene chloride. Total Petroleum
Hydrocarbons (TPH) are considered presumptive COPCs until proven otherwise. In general,
these contaminants are found in subsurface soils and groundwater. In groundwater,
contamination is found in a shallow aquifer that occurs between approximately 5 feet and 50
feet below ground surface (bgs). For the purposes of this RI Report, the upper zone of the
shallow aquifer refers to the portion at or above 25 feet bgs; the lower zone is the portion that
occurs deeper than 25 feet bgs and extends to the top of a silt and clay aquitard, which is
typically encountered at approximately 50 feet bgs. From 20 to 30 feet the shallow aquifer
appears to transition from high PCE concentrations in the upper zone to intermediate
concentrations of PCE before returning to high concentrations at depths greater than 30 feet.
This interval needs further characterization, but it suggests stratification as a result of the
groundwater flow regime and the tendency for PCE to sink.
A deeper aquifer underlies the Site and is separated from the shallow aquifer by the silt and
clay aquitard noted above. The deeper aquifer occurs at depths greater than 150 feet bgs in
the area of the HRIA. Sampling results for the deeper aquifer wells have historically been
"non-detect" for PCE, except for three isolated detections (Section 4.4.5).
Historical sampling results and data used to assess the nature and extent of contamination
across the Site are included in Tables 2-2 through 2-11 and Appendix A, and are discussed
in Section 4. The locations of all sampling points are shown on Plates 1, 2, and 3 in
Appendix B. Sampling points at and adjacent to the HRIA and the Breen Property are also
shown on Figures 2-1 and 2-2, respectively. Sampling points in Berwick Creek are shown
on Figure 2-3, and sampling points in Dillenbaugh Creek are shown on Figure 2-4.

Section 2 • Previous Environmental Investigations •
2.1 WDOH Drinking Water Investigation - 1993 -1994
As discussed in Section 1.3.3.1, WDOH sampled 18 private water-supply wells in the area (PW-1
through PW-18) in late 1993 and early 1994 as part of a routine sampling program. The private well
locations are shown on Figure 1-2; however, the locations of four private wells (PW10, PW11, PW12,
and PW18) were not well documented at the time and are presently unknown. PCE was detected at six
of the wells (PW-2, PW-3, PW-4, PW-5, PW-7, and PW-9) at concentrations ranging between 3.3 and
2,165 (ig/L. The highest PCE concentration occurred at PW-9 on the Thurman Property (Ecology
1999a).
2.2 WDOH Drinking Water Investigation - 1996
In June 1996, WDOH re-sampled 5 of the 6 PCE-contaminated water-supply wells identified during the
1993/1994 investigation and found that concentrations had increased slightly (Ecology 1999b). The five
wells re-sampled were PW-2, PW-3, PW-4, PW-5, and PW-9 (Figure 1-2). PCE concentrations ranged
from 5.8 to 3,009 (ig/L, with the highest concentration in PW-9.
2.3 Ecology Investigation - 1996-1997
In 1996, Ecology learned from a confidential source that drums containing solvents might have been
buried on the Breen Property and initiated an investigation to confirm this allegation. The investigation
included a geophysical survey by Geo-Recon International (Geo-Recon 1996) and a subsurface
investigation by SAIC as summarized below.
Soil Sampling
SAIC (1997) collected subsurface soil samples adjacent to and on the Breen Property using a hollow-
stem auger equipped with a split-spoon sampler. Eight borings (MW-1 through MW-8) were drilled and
all extended to the silt and clay aquitard below the shallow aquifer (average depth approximately 46
feet bgs). Soil samples were collected at various depths throughout the shallow aquifer down to 46 feet
and were analyzed for volatile organic compounds (VOCs) using EPA Method 8260. PCE
concentrations ranged from non-detect at the laboratory reporting limit (<0.004 milligrams per kilogram
[mg/kg]) to 0.023 mg/kg at MW-5.
Groundwater Sampling
SAIC installed monitoring wells in each of the eight borings described above and screened the bottom
10 feet of each well. The newly installed monitoring wells and select private wells were sampled.
Monitoring wells were purged using either disposable bailers or a Grundfos Redi-Flo2 submersible
pump. All samples were collected using disposable bailers. Samples were analyzed using EPA Method
8260. PCE was detected in monitoring wells MW-1 through MW-8 at concentrations ranging from 3 to
1,500 (ig/L. PCE concentrations in private wells PW-2, PW-3, PW-4, PW-5, PW-7, and PW-9 ranged
from 7 to 2,700 (ig/L.
2.4 Ecology Quarterly Groundwater Sampling - 1997-
2001
Between October 1997 and September 2000, Ecology performed quarterly sampling of the monitoring
wells installed by SAIC and some private water-supply wells, as well as collecting some limited soil
and surface water samples (Ecology 1999b and 2000). Additional sampling was conducted in 2001 but

the data was not formally reported by Ecology. Ecology provided a database containing the 2001 data
that has been included in the RI data set (Ecology 2001).
Soil Sampling
In January 1998, Ecology (1999b) collected six soil samples (SB-1 through SB-6) near PW-9 on the
Thurman Property using a JMC portable soil sampler. PCE concentrations were all non-detect at the
laboratory reporting limit (<1.6 mg/kg). The samples were analyzed by EPA Method 8260.
Information on the sample depth intervals has been lost; however, it is known that the samples were
surface or near surface samples as the hand-operated JMC sampler was only driven to a maximum
depth of 6 feet bgs during the investigation (Ecology 1999b).
Groundwater Sampling
In May 1999, Ecology installed monitoring and recovery wells MW-R1 through MW-R7 in the HRIA
(Figure 2-1 and Plate 1) (Ecology 2000). Based on a review of the 2000 investigation report, the
purposes of the wells were to serve as monitoring locations and, if deemed appropriate, as recovery
wells. Based on correspondence with EPA, the wells continue to serve as monitoring points and have
not been utilized as recovery wells (EPA 201 la). All wells were screened in the upper zone of the
shallow aquifer and PCE concentrations for groundwater ranged from 16 to 36,100 (ig/L at the time of
the investigation. The highest PCE concentration occurred at MW-R6.
Ecology continued quarterly monitoring of permanent monitoring wells MW-1 through MW-8 and
private wells PW-2 through PW-20 from October 1997 to September 2000 and began quarterly
monitoring of wells MW-R1 through MW-R7 once they were installed. Groundwater samples from the
monitoring wells were collected using a stainless-steel submersible pump and a low-flow sampling
technique. Samples were analyzed for VOCs using EPA Method 8260.
Diesel analysis was conducted on a sample from PW-21 (Figure 1-2). Diesel was non-detect at a
method reporting limit (MRL) of 16 (ig/L. The results are included in Appendix A, Table A-4.
Groundwater samples collected from two private wells (PW-5 and PW-21) were analyzed for semi-
volatile organic compounds (SVOCs) using EPA Method 8270. In addition, pesticides analysis was
conducted on a sample collected from PW-5. No SVOCs or pesticides were detected above laboratory
detection limits.
Surface Water Sampling
Four surface water samples were collected from Berwick Creek by Ecology. Samples were collected
directly into sample containers at the approximate midpoint of the creek channel. The samples were
identified as SW-1 through SW-4 (Figure 2-3) and were analyzed for VOCs. The results are
summarized in Table 2-4 and Appendix A, Table A-5. PCE concentrations ranged from non-detect at
the laboratory reporting limit (<1) to 16 (ig/L. The highest concentration of PCE occurred at SW-1.
2.5 Ecology Subsurface Investigation - 1998
In Spring 1998, Ecology contracted TEG to conduct an additional subsurface investigation (Ecology
1999a). TEG advanced 28 borings during two rounds of fieldwork conducted in March through April
1998.

Section 2 • Previous Environmental Investigations •
Soil Sampling
In March/April 1998, TEG collected surface and near surface soil samples from 7 of the 28 borings
(B21 through B27) utilizing direct-push technology (DPT) methods (e.g., Strataprobe™ or
Geoprobe®). Five of the seven borings encircled the United Rentals building and two were located on
the east side of Hamilton Road directly across from the United Rentals Building. Samples were
analyzed for specific halogenated VOCs using EPA Method 8010/8020. PCE concentrations ranged
from non-detect at the laboratory reporting limit (<0.05 mg/kg) to 5.24 mg/kg. PCE concentrations
were highest at B22.
Groundwater Sampling
TEG's March/April investigation also included collecting groundwater samples from 26 of the 28
borings (B1 through B8; B11 through B20; B23 through B27; and B2A through B2D) using DPT
methods. The borings were drilled at scattered locations around the Breen Property, along Hamilton
Road between the HRIA and Labree Road, and on the HRIA as described above for soil sampling.
Groundwater was sampled to depths of 35 feet bgs in the shallow aquifer from temporary wells
installed in the DPT borings (Ecology 1999a). Samples were collected using a combination of a
peristaltic pump and syringe to help minimize VOC loss. Samples were analyzed for specific
halogenated VOCs and benzene, toluene, ethylbenzene, and xylenes (BTEX) using EPA Method
8010/8020. Detected PCE concentrations ranged from 3.2 to 60,000 (ig/L. The highest PCE
concentration was detected in a groundwater sample collected at a depth of 20 feet bgs in B2. This
investigation identified a source area within the HRIA (situated around boring B2).
2.6 Breen Investigation and Drum Removal - 1999
In August 1999, Breen entered into an Agreed Order with Ecology and contracted for additional
investigations on the Breen Property. Activities included a geophysical survey conducted by Northwest
Geophysical Associates in August 1999, an additional investigation conducted by GeoEngineers, Inc. in
August/September 1999, and a drum removal remedial action conducted by GeoEngineers in
September 1999 (GeoEngineers 2001).
Drum Removal
In August 1999, prior to conducting a geophysical survey inside Building B, the concrete floor in the
southern end of the building was broken up using a hydraulic breaker and track-mounted excavator to
eliminate metal interferences in the floor for the survey. The broken concrete was removed using a
backhoe. The survey identified an anomaly in the southern portion of Building B where the slab had
been removed.
In August 1999, a backhoe was used to investigate the southern end of Building B where the anomaly
was detected. The backhoe encountered a drum a few inches below the surface and inadvertently
punctured it in the process. Approximately 20 gallons of water and sludge leaked into the exploratory
excavation. The area was then secured pending preparation of a work plan for drum removal.
In September 1999, 70 drums and a number of pails and cans were removed from beneath Building B
on the Breen Property, along with some impacted soil. All of the drums contained a black viscous
product (sludge) and water, as groundwater had seeped into leaking drums. The condition of the various
drums was not reported. Samples were collected from two of the drums to characterize the waste.
Results are summarized in Appendix A, Table A-7. Based on the laboratory results, the drums

appeared to contain "primarily lubrication oil, grease, and solvents typically associated with paint, paint
residue, and degreasing" (GeoEngineers 2001). PCE and its degradation products TCE and cis-1,2-
DCE were detected in the contents of the drums and in water samples collected from the drums and
excavation during drum excavations.
Petroleum staining, and petroleum and solvent odors were detected in soil during the drum removal.
GeoEngineers excavated and removed soil from the excavation based on field evidence of
contamination. Confirmatory soil samples were collected at 4 and 9 feet bgs along the walls of the
excavation and from the base of the excavation (ranging from 10 to 20 feet bgs). The samples were
analyzed for VOCs by EPA 802IB and gasoline-range or diesel-range petroleum hydrocarbons using
Northwest Methods NWTPH-Gx and NWTPH-Dx. Areas of the excavation where analytical results
indicated exceedances of the Washington State Model Toxics Control Act (MTCA) Method A and B
cleanup levels applicable at the time for petroleum hydrocarbons, PCE, and PCE degradation products
were over-excavated and re-sampled.
GeoEngineers pumped water that entered the excavation during remedial efforts to a 2,000-gallon
aboveground storage tank. A water sample from the excavation was collected for laboratory analysis.
Results are summarized in Appendix A, Table A-7. PCE was detected in a water sample collected
from the excavation at 2,800 (ig/L. Recovered water was treated using a granular activated carbon filter
and then transported to the City of Longview sewage treatment plant for disposal.
Confirmatory soil sample results from the excavation are summarized in Appendix A, Table A-l and
Table A-2. Soil samples collected from the drum removal excavation included EX-01 through EX-22,
and several miscellaneous locations shown as EX. PCE concentrations ranged from non-detect at the
laboratory reporting limit (<0.05 mg/kg) to 322 mg/kg. The highest PCE concentration was at a
miscellaneous EX location at a depth of 14 feet bgs.
Approximately 600 tons of soil were removed from the final excavation limits for offsite disposal. Soil
was removed up to a maximum depth of 20 feet bgs. Contaminants were either not detected or were
detected below MTCA Method A and B cleanup levels at the final excavation limits.
Additional Soil Sampling
GeoEngineers (2001) collected soil samples from the Breen Property using DPT methods at eight
locations (SP-1 through SP-8) and at various depths ranging from 2.5 to 12 feet bgs (Figure 2-2).
Borings SP-1 through SP-3 were located just west of the wash-down pad and borings SP-5 through SP-
8 were located around Building B. These boring samples were analyzed for VOCs using EPA Method
8021B. PCE concentrations ranged from less than laboratory reporting limits (<0.05 mg/kg) to 0.0586
mg/kg. The highest PCE concentration was at SP-7.
Groundwater Sampling
GeoEngineers collected groundwater samples from temporary wells installed in SP-1 through SP-8 at
depths of 15 and 40 feet bgs using a peristaltic pump. Samples were analyzed for VOCs using EPA
Method 8021B. PCE concentrations ranged from non-detect at the laboratory reporting limit (<1.0
(ig/L) to 1,170 (ig/L. The highest concentration of PCE was detected in the sample collected at a depth
of 40 feet bgs in SP-4.

Section 2 • Previous Environmental Investigations •
Investigation of Vertically-Oriented Pipe (Torpedo Tube)
On December 7, 1999, GeoEngineers evaluated a vertically-oriented pipe located in the ground west of
Building B (GeoEngineers 2001). The purpose of the pipe is unknown but Ecology suspected it may
have been used for disposal. GeoEngineers reported the pipe as being 23 inches in diameter and
extending down approximately 13 feet. Groundwater was encountered at 9 feet bgs within the pipe at
the time of the investigation. GeoEngineers collected a water sample from the pipe for analysis of
halogenated VOCs by EPA Method 8021B. Halogenated VOCs, including PCE, were not detected.
Ecology used markings observed on the pipe to track that it had originally been a military transport
container for a torpedo. After this discovery, the vertically-oriented pipe was subsequently identified as
the Torpedo Tube (Figure 2-2 and Plate 1).
2.7 EPA START Phased Removal Assessment - 2000-
2001
In 2000, the EPA START contractor, E&E, began a phased removal assessment, which included
installing soil borings and groundwater monitoring wells and collecting subsurface soil and
groundwater samples in and near the HRIA. The assessment resulted in the expansion of the City of
Chehalis municipal water-supply system as discussed in Section 1.3.3.5. E&E conducted four phases of
investigations in the HRIA.
Soil Sampling
Phase I investigations (E&E 2000) occurred in June and July 2000 and included collection of surface,
near surface, and subsurface soil samples (AB-1 through AB-10, GP-1 through GP-4, GP-A3, and GP-
A4) using DPT or hollow-stem auger rigs. Samples were collected at multiple depths throughout the
shallow aquifer (down to 44-48 feet bgs) at AB-1 through AB-10 and from GP-A3 and GP-A4.
Samples from GP-1 through GP-4 were collected from multiple depths down to 28 and 32 feet. PCE
concentrations ranged from non-detect at the laboratory reporting limit (<0.07 mg/kg) to an estimated
13 mg/kg. The highest PCE concentration was found at GP-4. Samples were either analyzed by EPA
Method 8260 and/or by the Environmental Services Assistance Team (ESAT) mobile laboratory.
Phase II investigations (E&E 2000) were conducted in August 2000 and included collecting soil
samples from one boring (AB-11) and during monitoring well and additional dual purpose
monitoring/recovery well installations1 (MW-9, MW-10, and MW-R8 through MW-R11). Borings
were drilled using a hollow-stem auger equipped with a split-spoon sampler. Samples were collected at
multiple depths down to about 35 feet bgs. PCE concentrations ranged from non-detect at the laboratory
reporting limit (<0.064 mg/kg) to an estimated 53 mg/kg. The highest PCE concentration was found at
MW-9.
Phase III investigations (E&E 2001) occurred in January and February 2001 and included collecting
soil samples during installation of additional monitoring wells (MW-11 through MW-16) on the
northeast side of 1-5. Monitoring well borings were drilled using a hollow-stem auger equipped with a
1 Similar to the 1999 Ecology site investigation, the purposes of the dual purpose monitoring/recovery wells were
to serve as monitoring locations and, if deemed appropriate, as recovery wells. Based on correspondence with
EPA, the wells continue to serve as monitoring points and are not serving as active recovery wells (EPA, 201 la).

split-spoon sampler. PCE was not detected in the soil samples above laboratory reporting limits.
Reporting limits ranged from 0.059 to 0.071 mg/kg.
Phase IV investigations (E&E 2002) were conducted in October and November 2001 to assist in the
evaluation of a proposed water supply pipeline route. Ninety soil borings were installed (GP-102
through GP-191), and samples were collected at depths of up to 8 feet bgs every 50 feet along North
Hamilton Road to the intersection with Labree Road using DPT methods. Samples were analyzed for
VOCs using EPA Method 8260. PCE concentrations ranged from non-detect at the laboratory reporting
limit (<0.001 mg/kg) to 0.11 mg/kg. A soil sample collected at GP-163 contained the highest PCE
concentration.
Groundwater Sampling
Phase I investigations (E&E 2000) in June and July 2000 included collecting groundwater samples
from temporary wells installed in DPT borings AB-1 through AB-10, GP-1 through GP-3, GP-A3, and
GP-A4. Samples were analyzed by EPA Method 8260. PCE concentrations ranged from non-detect at
the laboratory reporting limit (<1 (.ig/L) to 190,000 (ig/L. The highest PCE concentration was detected (
in a sample collected at 16 feet bgs in GP-1. J
Two groundwater samples, GP-1 and GP-3, were analyzed for gasoline-range total petroleum
hydrocarbons (TPH-G) using NWTPH-Gx. A concentration of 4,200 (ig/L was detected at GP-1.
TPH-G was non-detect at a MRL of 100 (ig/L in GP-3.
Phase II investigations (E&E 2000) in August 2000 included sampling existing monitoring wells
(MW-1 through MW-8, and MW-R1 through MW-R7), private wells (PW-3, PW-9, and PW-14) and
newly installed HRIA monitoring wells (MW-9, MW-10, and MW-R8 through MW-R11). MW-9 and
MW-10 were screened in the lower 20 feet of the shallow aquifer, and MW-R8 through MW-R11 were
screened across all or most of the aquifer thickness. PCE concentrations ranged from non-detect at the
laboratory reporting limit (<1 (.ig/L) to 44,000 (ig/L. The highest PCE concentration was detected in
MW-9. Samples were analyzed by EPA Method 8260.
Phase III investigations (E&E 2001) occurred between January and May 2001. The investigations in
January and February 2001 included sampling existing monitoring wells and private wells. In addition,
upgradient monitoring wells MW-11 through MW-16 were installed along the northwestern edge of 1-5
and sampled. PCE concentrations in monitoring wells (MW-1 through MW-16), monitoring and
recovery wells (MW-R1 through MW-R11), and private wells (PW-3, PW-4, PW-6, PW-9, and PW-20)
ranged from non-detect at the laboratory reporting limit (<1 (.ig/L) to 56,000 (ig/L. The highest PCE
concentration was detected in MW-R5. Samples were collected from the monitoring wells using
dedicated, submersible Easy Pumps. Samples from the private wells were collected using the dedicated
well pump.
Additional sampling of private wells was conducted in May 2001 (E&E 2002). Detected PCE
concentrations from private wells PW-4, PW-7, PW-16, PW-17, PW-21, and PW-22 ranged from 3
(ig/L at PW-4 to 710 (ig/L at PW-7. PW-7 is located just downgradient of the Thurman Berwick Creek
Area. Samples from the private wells were collected using the dedicated well pump.
Phase IV investigations (E&E 2002) were conducted in October and November 2001. PCE
concentrations from monitoring wells (MW-1 through MW-10), monitoring/recovery wells (MW-R1
through MW-R11), and private wells (PW-1, PW-3 through PW-9, PW-16, PW-17, and PW-21 through

PW-37) ranged from non-detect at the laboratory reporting limit (<1 (.ig/L) to a maximum of 61,000
(ig/L. The highest PCE concentration was detected in MW-R5. Monitoring wells were sampled using
dedicated, submersible EasyPumps, except on the Breen Property where dedicated bailers were used.
Samples from the private wells were collected using the dedicated well pump.
2.8 Breen Phase I RI - 2002 and Phase II RI - 2003-2004
In accordance with the AOC signed by EPA and Breen in 2001, Breen (through their consultant,
Farallon) initiated Phase I RI activities in July 2002 under EPA oversight to investigate the COPCs in
the shallow aquifer at the Breen Property and in the Thurman Berwick Creek Area. Farallon used DPT
sampling methods to collect soil and groundwater samples on the Breen Property and in the Thurman
Berwick Creek Area. They also conducted a soil gas investigation on the Breen Property, collected
surface water and stream-bed soil samples from Berwick Creek, and sampled groundwater from
existing monitoring and private water-supply wells across the Site (Farallon 2003).
Beginning in late 2003, Farallon initiated Phase II RI sampling to better define the nature and extent of
contamination on and downgradient of the Breen Property and in the Thurman Berwick Creek Area. |
Activities included soil and groundwater sample collection, installing and sampling monitoring wells, j
surface water sample collection, completion of a pump test, and various other activities (Farallon 2004).
Phase II RI activities ended in 2004 when EPA and Breen began negotiating a cash-out settlement. EPA {
received data collected in 2003 by Farallon, but a Phase II RI Report was never submitted by Breen.
The data and EPA's interpretation of the data are presented in this RI Report to better understand Site-
wide groundwater contamination, particularly with respect to contamination attributable to the HRIA.
Soil Sampling
In June/July 2002, Farallon collected soil samples at reconnaissance stations (RS-1, RS-2, RS-5, RS-8,
RS-8A, RS-9, RS-12, and RS-16); at monitoring wells MW-18, MW-19, and MW-21 on the Breen
Property (Figure 2-2); at monitoring wells MW-23 and MW-24 located between the HRIA and the
Thurman Berwick Creek Area (Figure 2-1), and at monitoring well MW-25 located in farmland
approximately 2,200 feet northwest of the Breen Property. Soil samples were collected at depths
between 5 and 49 feet bgs. Soil sampling was completed primarily using a hollow-stem auger, but
several samples were collected using DPT methods. Samples were analyzed using EPA Method 8260.
PCE concentrations ranged from 0.003 mg/kg to an estimated 0.36 mg/kg. The highest PCE
concentration was detected in RS-2 at a depth of 5 feet bgs.
In September 2003, Farallon collected soil samples from two hollow stem auger borings, RS-30 and
RS-31, located in the Thurman Berwick Creek Area. Sample depths were between 15 and 20 feet bgs.
Samples were analyzed using EPA Method 8260. PCE concentrations ranged from 0.027 mg/kg to an
estimated 1.3 mg/kg. The highest PCE concentration was detected in a soil sample collected from
RS-31.
In April 2004, Farallon collected surface soil samples from two borings (CB-1 and CB-2) situated along
Berwick Creek just north of where the creek crosses under North Hamilton Road, and from one boring
(DB-1) located in a drainage ditch south of the Breen wash-down pad. Soil sampling was completed
primarily using hand augers. Samples were analyzed using EPA Method 8260. PCE concentrations
were non-detect at the laboratory reporting limit (<0.0015 mg/kg) in all samples.

Section 2 • Previous Environmental Investigations •
Groundwater Sampling
Farallon collected groundwater samples in June/July 2002, August 2002, November 2002, February
2003, August/September 2003, November 2003, April 2004, and June 2004 (Farallon 2003 and 2004).
Samples were collected using low-flow sampling procedures from existing monitoring wells (MW-1
through MW-14 and MW-R1 through MW-R11), private wells (PW-1, PW-3 through PW-9, PW-21,
PW-23, PW-24, PW-26, PW-32, PW-34, and PW-36 through PW-39), and temporary wells installed at
reconnaissance station locations on or downgradient of the Breen Property and in the Thurman Berwick
Creek Area (RS-1 through RS-24, RS-30, RS-31, RS-33, RS-41 through RS-43, and RS-46 through RS-
49).
New monitoring wells were installed on the Breen Property (MW-17 through MW-21, MW-33, and
MW-34), in the Thurman Berwick Creek Area (MW-31 and MW-32), and between the HRIA and the
Thurman Berwick Creek Area (MW-22 through MW-24). In addition, monitoring wells were installed
approximately 2,200 feet downgradient (MW-25) and 6,400 feet downgradient (MW-28) of the Breen
Property. Half of the new wells were screened in the lower zone of the shallow aquifer (MW-18, MW- j
19, MW-21, MW-23 through 25, and MW-27), and nearly half were screened in the upper zone (MW- |
17, MW-20, MW-26, MW-28, MW-29, and MW-31 through MW-33). MW-34 was screened across |
nearly the full thickness of the aquifer.
PCE concentrations in groundwater sampled from existing wells were comparable to or less than
concentrations found during previous investigations (e.g., Ecology or E&E). PCE in the "RS" set of
samples ranged from 1.1 to 2,400 (ig/L. The highest PCE concentration was detected in RS-7, located
near the wash-down pad, at a depth of 24 feet bgs. PCE concentrations in the newly installed
monitoring wells ranged from non-detect at the laboratory reporting limit (<0.2 (ig/L) to 2,300 (ig/L.
The highest PCE concentration was detected in MW-31 located in the Thurman Berwick Creek Area.
Surface Water Sampling
Farallon collected four rounds of surface water samples from Berwick Creek between July 2002 and
November 2003. Samples were collected from six stations, SW-5 through SW-10 (Figure 2-3). The
surface water stations are primarily located near the Breen Property or in the vicinity of the HRIA.
Samples were collected using a peristaltic pump with dedicated tubing. A rigid sampling pole was used
to insert the flexible tubing into the stream channel. The tubing intake was placed mid-channel and to a
depth that was approximately six-tenths of the depth from the stream surface to the stream bottom.
The surface water samples were analyzed for VOCs and the results are summarized in Table 2-4 and
Appendix A, Table A-5. PCE concentrations ranged from non-detect at the laboratory reporting limit
(<0.2) to 40 (ig/L. The November 2002 SW-5 sample contained the highest PCE concentration. Its
duplicate sample was only half as much (20 (ig/L). but still higher than other sampling station results
found during this sampling event and subsequent surface water sampling events completed by EPA.
Farallon also analyzed the six July 2002 surface water samples for gasoline-range petroleum
hydrocarbons. The samples, collected from surface water monitoring stations SW-5 through SW-10,
were non-detect for gasoline at a MRL of 100 (ig/L. Results for the six surface water samples are
summarized in Appendix A, Table A-6.

Section 2 • Previous Environmental Investigations •
Creek Bed Sediment/Soil Sampling
Creek channel sediment samples CC-1 through CC-9 were collected by Farallon (2004) during Breen
Phase IIRI/FS sampling (Figure 2-3). The samples were collected from various locations along
Berwick Creek in the Thurman Berwick Creek Area south of the Breen Property. The samples were
collected from the creek bed sediment at a depth of approximately 1 foot bgs using a hand-held
diameter drive sampler. PCE was not detected in any of the samples.
Soil Gas Sampling
Farallon conducted a soil gas survey in November 2002 at two areas (near RS-l/RS-2 and RS-7) on the
Breen Property to better define potential PCE sources. PCE was not detected in any of the soil gas
samples, so it was concluded that these areas do not contain a PCE source. Soil gas analytical results
are shown in Table 2-6.
2.9 EPA Engineering Evaluation/Cost Analysis
Investigation at the HRIA - 2003
In 2003, EPA contractor URS Group, Inc. (URS) began additional field investigations at the HRIA to
support completion of an Engineering Evaluation/Cost Analysis (EE/CA) (URS 2004). The purpose of
the field investigation was to better define the extent of soil and groundwater contamination, including
defining the extent of dense non-aqueous phase liquid (DNAPL) in the Berwick Creek bed and the
shallow aquifer as related to a potential release or spill into Berwick Creek (which was estimated to
have occurred around 1990 based on plume migration information but the exact date of the spill/release
is unknown). URS also evaluated potential alternatives for remediation of contamination in the HRIA;
however, a remedy was not chosen at that time because additional investigations were required to
determine the nature and extent of contamination.
Soil Sampling
During the investigation, URS collected soil samples from monitoring well borings (MW-600 through
MW-608), DPT borings (GP-500 through GP-518), and auger borings (AB-650 through AB-652).
Samples were collected at several depths between approximately 2 and 50 feet bgs in MW-600 through
MW-605 and in AB-650 through AB-652. Samples were collected at various depths to a maximum
depth of 30 feet bgs in GP-500 through GP-518, and at several depths between 31 feet bgs and the top
of the silt and clay aquitard at approximately 50 feet bgs in MW-606 through MW-608.
A total of 359 samples were collected using DPT or hollow-stem auger drilling methods. Soil samples
were collected and preserved with methanol in accordance with EPA Method 5035. Samples were
analyzed for PCE using the mobile laboratory (ESAT) and/or EPA Method 8260. The maximum
concentration of PCE, 3,220 mg/kg, was detected at GP-502 at a depth of 28 feet bgs. Results are
summarized on Table 2-2.
Select soil samples were also analyzed for a variety of physical characteristics and metals. The results
are summarized in Tables 2-9 and 2-10.
Groundwater Sampling
During the EE/CA investigation, groundwater samples were collected from newly installed monitoring
wells and from temporary test wells installed in DPT and hollow-stem auger borings. New wells MW-
600 through MW-608 were screened across all or most of the shallow aquifer, but sampling at multiple

depths was conducted when the wells were installed. Groundwater samples were collected at the DPT
boring locations using a temporary stainless steel well screen (Screen Point 16 Groundwater Sampler)
inserted through the rods. Groundwater samples were collected from hollow-stem auger borings using
the hydropunch method. Samples were analyzed using ESAT PCE analysis and/or EPA Method 8260.
The sampling event targeted the projected PCE release area north of North Hamilton Road around
Berwick Creek, although MW-606 through MW-608 were installed along a line about 200 feet
downgradient of the Berwick Creek source area. Detected PCE concentrations from new wells (MW-
600 through MW-608) ranged from 55 to 2,720,000 (ig/L. The highest PCE concentration was detected
in MW-602 at a depth of 14.5 feet bgs. This high concentration of PCE is an order of magnitude higher
than its solubility limit in water, indicating that DNAPL was present in the groundwater sample. The
maximum PCE concentration in groundwater samples from DPT borings (GP-500 through GP-531) and
auger borings (AB-650 through AB-652) occurred in a sample collected between 14 and 16 feet bgs at
GP-501, which contained 217,000 (ig/L. Groundwater sampling depths were limited to a maximum of
32 feet bgs in GP-500 through GP-531; in contrast, the sampling depths in AB-650 through 652 ranged
from 34 to 46 feet bgs. |
Conventional chemistry analyses (sulfate, sulfides, nitrate/nitrites, chloride, iron, and alkalinity) were j
conducted on samples collected from 9 wells within the HRIA during the EE/CA investigation (URS
2004). The results of these analyses are shown in Table 2-11.
Long-term pumping tests were also conducted in wells MW-602 and MW-605 to determine horizontal
hydraulic conductivity; results are summarized in Section 3.3.
Creek Bed Sediment/Soil Sampling
URS collected a total of 39 bed and bank sediment samples (BS-451 through BS-470 and SB-400
through SB-419) from Berwick Creek and the two unnamed ditches that discharge to Berwick Creek, in
order to aid in HRIA source area identification and delineation. Creek bed samples were collected from
0 to 1 foot below the surface of the creek bed using a hand-held drive-point tool called a Large Bore
Sampler. Creek bank samples were collected using the same tool driven to a depth of 2 to 3 feet bgs.
The maximum PCE concentration detected in the samples was 5,220 mg/kg at SB-409. The results of
the sampling provided strong evidence of a release to Berwick Creek between the two unnamed ditches.
Analytical results from all creek sediment/soil samples are shown in Table 2-5.
Soil Gas Sampling
URS collected soil gas samples in the vicinity of Berwick Creek and 1-5, north of the HRIA, using DPT
and a vacuum pump (Figure 2-1; SG-200 through SG-205, SG-207 through SG-209, and SG-211
through SG-236). As a quality assurance check, two samples were collected from locations where PCE
was not expected to be present (SG-201 and SG-203); PCE was not detected in either sample. Three
samples were collected from areas where PCE was expected to be present (SG-202, SG-204, and SG-
205) and PCE was detected in each of these samples. The remaining samples were used to assess the
probability of a spill along 1-5. PCE concentrations in the remaining samples were generally very low.
All but two samples contained PCE at concentrations less than 1 part per million by volume [ppm-v].
The results of the URS investigation indicated that the Berwick Creek contamination at the HRIA was
likely not related to a spill from 1-5. Soil gas analytical results are summarized in Table 2-6.

2.10 EPA Supplemental Groundwater and Surface Water
Sampling - 2007
In July 2007, Parametrix, on behalf of EPA, conducted supplemental groundwater and surface water
sampling across the Site, focusing on the areas immediately downgradient of the HRIA, on the Breen
Property, and in the Thurman Berwick Creek Area (Parametrix 2009). Samples were also collected
from private wells along Rice Road west of Labree Road, an area that had not been previously sampled,
and private wells that had historically contained PCE. The data from this event were used to further
define the groundwater contamination, to assess contaminant migration, and to assess potential
groundwater-surface water interaction associated with Dillenbaugh Creek.
Groundwater Sampling
Using low-flow sampling procedures, Parametrix sampled 17 existing wells, including 8 private wells
and 9 monitoring wells in the HRIA, the Breen Property, the Thurman Berwick Creek Area, and
downgradient areas west of Labree Road to evaluate whether significant changes in concentrations had
occurred since the previous Site-wide sampling event in 2003/2004. Field parameters were collected |
during the July 2007 sampling event and are summarized in Table 2-12. j
The private wells sampled included five locations beyond the end of the public water supply line
installed in 2002 (Figure 1-3). PCE concentrations in these wells were all non-detect at the laboratory
reporting limit of 1.0 (ig/L. The maximum PCE concentration of 14 (ig/L was detected in the remaining
private well (PW-4) located south of the Thurman Berwick Creek Area. While PCE was non-detect at
the laboratory reporting (<0.2 (ig/L) in PW-4 in 2003, the concentration of PCE in 2007 was much less
than typically observed during the 1990s and up to 2001 when PCE concentrations were typically an
order of magnitude higher.
For the monitoring wells, the maximum concentration of PCE was observed at MW-R7 (6,100 (ig/L).
located adjacent to North Hamilton Road, east of the United Rental building. This PCE concentration is
consistent with 2003 results and higher than PCE concentrations reported in 1990-2002. Concentrations
of PCE in the other 8 monitoring wells located southeast of the Thurman Berwick Creek Area ranged
from 600 (ig/L at MW-25 (located west of Labree Road) to 2,700 (ig/L at MW-32 (2,500 (ig/L in the
duplicate sample collected from MW-32). PCE concentrations in monitoring wells in and upgradient of
the Thurman Berwick Creek Area were within the same order of magnitude as those concentrations
observed in 2003 and not notably different, particularly considering that the same magnitude of
variation was sometimes observed between different 2002/2003 sampling events. For example, at MW-
21, the PCE concentration was 1,500 (ig/L in November 2002, 1,800 (ig/L in February 2003 and 1,500
(ig/L in July 2007. In MW-30, the PCE concentration was 1,700 (ig/L in September 2003, 1,300 (ig/L
in November 2003, and still 1,300 (ig/L in July 2007.
Surface Water Sampling
Two surface water samples (CS-1 and CS-2) were collected from Dillenbaugh Creek by Parametrix in
July 2007 (Figure 2-4). These samples were collected near monitoring well MW-25, located
approximately 2,200 feet northwest of the Breen Property. Concentrations of PCE in surface water
ranged from 1.7 (ig/L at CS-1 to 3.6 (ig/L at CS-2. Surface water analytical results for PCE, TCE, and
cis-l,2-DCE are summarized in Table 2-4. Results for other VOC analyses and petroleum analysis are
summarized in Appendix A, Tables A-5 and A-6, respectively.

2.11 EPA Air Sampling - 2007
In November 2007, EPA's Emergency Response Team (ERT) conducted air sampling in and around
private residences and commercial buildings across the Site to assess potential risks to human health
from volatilization of contaminants from groundwater to indoor and ambient air (Lockheed Martin
2008, EPA 2008). A total of 34 samples were collected over a 24-hour time period using SUMMA
canisters. The samples were analyzed for VOCs, including PCE, TCE, cis-l,2-DCE, trans-1,2-DCE,
1,1-DCE, methylene chloride, and vinyl chloride.
Vapor intrusion sampling consisted of collecting air samples within residences and commercial
building and crawlspaces (if present). Ambient air samples were also collected at several outdoor
locations near the residential and commercial buildings. In addition, soil vapor samples were collected
from beneath the concrete floor slabs at five commercial buildings and one residence. These samples
were collected by coring through the concrete slab and installing a temporary soil gas well. Sampling
locations are described in Table 2-7.
Low levels of PCE were detected in the majority of the residential, commercial, and ambient locations.
Further discussion of air sampling results is presented in Section 4.8, and analytical results are
summarized in Table 2-8.
2.12 EPA Water Level Measurements - 2010
In May 2010, EPA measured water levels and assessed the condition of most of the monitoring wells at
the Site. The results of the assessment are detailed in a report contained in Appendix C.

Section 3
Physical Characteristics of the Site
This section describes the physical characteristics of the Site. The description includes the
regional and Site-wide topography, drainage, climate, geology, hydrogeology, surface water
hydrology, land and groundwater uses, and current ecological conditions.
3.1 Topography, Drainage, and Climate
The Site lies within the Newaukum Prairie, a relatively flat area formed by the Newaukum
River. Hills bound the Prairie to the west and east, rising to elevations of 400 to 700 feet
above mean sea level (MSL). Site topography ranges from 195 to 210 feet above MSL.
Surface water drainage varies from location to location within the area depending on the
proximity of surface water features such as Berwick Creek, Dillenbaugh Creek, and the
Newaukum River. The valley generally slopes down to the northwest towards the Chehalis
River. The regional topography and drainages are shown in Figure 3-1.
The Newaukum River flows northwesterly towards its confluence with the Chehalis River
about five miles northwest of the Site. Berwick Creek flows through the Site in a general
northwest direction and joins Dillenbaugh Creek approximately 1,500 feet northwest of the
Breen Property (Figure 3-1). Dillenbaugh Creek flows to the northwest and discharges into
the Chehalis River.
Average annual precipitation in the Chehalis area is approximately 47 inches, with December
being the wettest month (Western Regional Climate Center 2006). An estimated three-
quarters of the annual precipitation falls during October through March. The climate of the
region includes wet winters and moderately warm, dry summers. The mean average annual
temperature for the Chehalis area is about 50 degrees Fahrenheit (°F).
3.2 Regional and Site Geology
Surficial deposits mapped for the Site area consist of alluvium and Newaukum terrace unit
glaciofluvial deposits (Weigle and Foxworthy 1962). The alluvial deposits appear to be what
is referred to as the "silt cap" that is reportedly continuous across the Site and ranges between
1 and 15 feet thick. This silt cap is logged as "clay" by some investigators and locally
contains sand lenses and stringers. In some cases the silt grades to a silty sand or silty gravel
at its contact with the underlying glaciofluvial sediments. This "cap" creates locally confined
groundwater conditions in the underlying shallow aquifer.

Hamilton-Labree\7-Proiect DocumentsYRI Reoort\Text\Draft Hamilton Labree Roads RI
-------
Section 3 • Physical Characteristics of the Site •
The Newaukum terrace unit that underlies the alluvial silt cap is a glaciofluvial deposit consisting of
sand in a silt and clay matrix. Its maximum depth is approximately 50 feet bgs. Logged soil types
within the sand and gravel typically range from fine-grained, poorly sorted sand to coarse gravel, with
cobbles prevalent. The silt content of the Newaukum unit sands and gravels varies substantially
throughout the unit, with some zones classified as silty sands and silty gravels and other zones
classified as clean sands or gravels. The correlation in soil types between nearby borings is poor,
indicating a high degree of variation in grain size or silt content within the shallow aquifer. A somewhat
laterally extensive bed of poorly sorted sand was identified in borings around Berwick Creek at a depth
of about 30 feet bgs. This bed is one of the few examples of a reasonable correlation of a distinct soil
layer across multiple borings. Silt lenses ranging from 1 to 7 feet thick have been identified within this
unit. This unit contains the shallow aquifer.
The Newaukum terrace unit is underlain by a non-marine sedimentary unit described as thin-bedded
"blue" clays (with occasional sand and silt lenses). This bluish-gray clayey silt layer is approximately
100 feet thick and is indurate with depth (Dames and Moore 1994). This layer is believed to be
Miocene-Pliocene (Weigle and Foxworthy 1962) and has a fluvial or lacustrine origin. This unit is the
aquitard that divides the shallow and deep aquifers at the Site. It appears to be continuous beneath the
Site, which is consistent with regional geologic information (Ecology 2005).
Below the silt and clay aquitard is a confined aquifer comprised of older Miocene alluvial sediments
deposited by a meandering or braided river system. The groundwater in the deep aquifer occurs in sand
lenses and channel deposits ranging from 5 to 70 feet thick and more than 150 feet deep in the area of
the HRIA (Dames and Moore 1994). Wells installed in this aquifer in the Newaukum River valley are
typically artesian. Private well PW-23 was installed in this aquifer to replace the shallow aquifer well
PW-2 located at the south end of the HRIA.
In summary, the current understanding of the Site stratigraphy is as follows:
Alluvially deposited silt "cap" 1 to 15 feet thick
Glaciofluvially deposited sand and gravel in a silt and clay matrix 35 to 50 feet thick unit (the
shallow aquifer) (Newaukum terrace unit)
Non-marine sedimentary silt to clay deposit 100 feet thick (aquitard)
Miocene alluvial sediments, thickness unknown (deep aquifer)
Cross-sections illustrating the distribution and thickness of the geologic units encountered beneath the
Site were prepared by Farallon (2003) and URS (2004). Additional cross-sections were also completed
between the HRIA and the southeastern corner of the Breen Property along the approximate
groundwater flow direction, and from the HRIA through the Thurman Berwick Creek Area. New and
previously completed Site cross-sections are included in Appendix D. Boring and well logs used to
prepare the cross-sections are provided in Appendix E.
3.3 Hydrogeology
The groundwater flow direction beneath the HRIA is to the west/northwest, but becomes northwesterly
downgradient of the Breen Property. Historical water levels are listed on Table 3-1. Historic static
water levels have ranged between approximately 1.5 and 10 feet bgs (taking into account whether the

monument is a flush mount, or riser). Water levels can vary several feet seasonally. In any individual
well, as much as a 6.47 foot difference has been observed. The highest water level fluctuations have
been observed at MW-3, where water levels have ranged from 4.05 feet below the top of casing in
February 1997 to 10.52 feet below the top of the casing in September 2002. Groundwater elevation
contour maps for the November 2003 and July 2007 monitoring events are shown in Figures 3-2a, 3-
2b, and 3-3. Groundwater elevation contours which focus on the source areas for November 2003 are
shown in Figure 3-4.
Regional investigations conducted by others (Dames and Moore 1994; Ecology 2005) have categorized
the shallow aquifer in the area as an unconfined or semi-confined aquifer. However, in the HRIA, the
shallow aquifer exhibits the characteristics of a confined or semi-confined aquifer, primarily due to the
silt cap immediately above the aquifer and water levels measured 4 to 6 feet above the base of this silt
in December 2003 (URS 2004).
The mean vertical hydraulic conductivity of the silt capping the shallow aquifer was measured in the
laboratory at 6.3 x 10"7 centimeters per second (cm/s) using soil cores collected during the HRIA
EE/CA investigations (URS 2004). The silt cap of the shallow aquifer exhibits vertical hydraulic
conductivities less than the 8 x 10"6 cm/s, which is representative of confining layers (Fetter 1980).
In 2000, short-term aquifer pumping tests (over a 55-minute time period) were conducted at HRIA
monitoring wells MW-R10 and MW-R11 (E&E 2000). Both of these monitoring wells are screened
from 19 to 49 feet bgs. The horizontal hydraulic conductivity in the HRIA was estimated at 4.4 x 10"2
cm/s or 125 feet per day (ft/d) with a flow rate of 14 gallons per minute (gpm) for each well.
The horizontal hydraulic conductivity was also estimated at wells MW-602 and MW-605 based on
long-term pumping tests (between 20 to 25 hour time periods) completed during the EE/CA (URS
2004). The tests were conducted at sustainable flow rates of 25 and 6 gpm, respectively. The mean
hydraulic conductivity estimated based on these tests was 4.9 x 10"3 cm/s (13.9 ft/d). The range of
hydraulic conductivities estimated using the Theis equation for a confined aquifer was 1.7 x 10"3 to 6.0
x 10"3 cm/s (4.8 to 17.0 ft/d). The distance-drawdown analyses for wells downgradient of MW-602,
crossgradient of MW-605, and upgradient of MW-605 resulted in estimates of hydraulic conductivity
ranging from 3.1 x 10"3 to 6.0 x 10"3 cm/s (8.8 to 17.0 ft/d). The distance-drawdown analysis for wells
crossgradient of MW-602 (i.e., parallel to Berwick Creek) resulted in a hydraulic conductivity
estimation of 4.9 x 10~2cm/s (139 ft/d).
Calculated hydraulic conductivity for pump testing completed at the Breen Property showed a value
between 5.1 xlO"3 to 6.4 x 10"3 cm/s (14.5 and 18.0 ft/d). No hydraulic conductivity data are available
for the downgradient areas west of Labree Road.
The overall groundwater gradient beneath the HRIA is 0.0063 foot per foot (ft/ft) (URS 2004). A
localized steeper gradient (approximately 0.016 ft/ft) is apparent immediately downgradient of North
Hamilton Road. The average regional gradient in the area of the Site is 0.0055 ft/ft (Ecology 2005).
The groundwater flow rate, or seepage velocity, beneath the Site can be calculated based on the
hydraulic conductivity, the average regional groundwater gradient, and the mean effective porosity of
the aquifer material (Fetter 1980). The formula for seepage velocity is as follows:
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
23
-------
Section 3 • Physical Characteristics of the Site •
vs = (k)(i)/ne
Where:
vs - seepage velocity (ft/d)
k - hydraulic conductivity (ft/d)
i - groundwater gradient (ft/ft)
ne - effective porosity
Using the horizontal hydraulic conductivity of 4.8 to 139 ft/d, the HRIA gradient of 0.0063 ft/ft, and an
average effective porosity of 0.25, the seepage velocity would range from approximately 0.12 to 3.50
ft/d. Using the average hydraulic conductivity of 13.9 ft/d derived from pumping tests in the HRIA
produces a seepage velocity of 0.34 ft/d. However, using the E&E average groundwater gradient for
the entire Site of 0.0032 ft/ft and the horizontal hydraulic conductivity range of 4.8 and 139 ft/d, the
seepage velocity would range from approximately 0.06 to 1.78 ft/d. If the HRIA average hydraulic
conductivity of 13.9 ft/d and the Site-wide gradient of 0.0032 ft/ft is used in the equation, a seepage
velocity of 0.18 ft/d is calculated (E&E 2000).
This average hydraulic conductivity (13.9 ft/d) is comparable to the values obtained from pumping tests
conducted at the Breen Property. However, it does not incorporate the higher HRIA hydraulic
conductivity data from the short-term pumping tests or the cross-gradient distance-drawdown data. If
these higher hydraulic conductivities are limited to the HRIA, then the Site-wide seepage velocity of
0.18 ft/d is reasonable. However, if the higher hydraulic conductivities occur beyond the HRIA, the
Site-wide seepage velocity of 0.18 ft/d would underestimate the rate of groundwater flow. Moreover, it
would not be possible for significant concentrations of PCE to reach MW-25 or RS-20 in 2002 at a
groundwater flow rate of 0.18 ft/day unless the source at the Breen Property and/or the Thurman
Berwick Creek Area is more than 50 years old, which is unlikely, given the history of Site development
or there is another unaccounted for source nearer to these wells.
Site-wide vertical gradients within the shallow aquifer are poorly understood. There are only five
locations with paired monitoring wells screened in the shallow aquifer, and only four of those locations
have synoptic water level data from both wells (Table 3-2). Of these well clusters, two are in the
southwestern area of the Breen Property, one in the northwestern area of the Breen Property, and one is
just south of North Hamilton Road between the HRIA and the Thurman Berwick Creek Area. The three
locations within 200 feet of Berwick Creek (MW-20/21, MW-22/23, and MW-29/30) have upward
gradients, while the cluster located further away (MW-17/18) has a downward gradient.
Since completion of the City water main extension in November 2002, production wells local to the
HRIA and Thurman Berwick Creek Areas have not been influencing the groundwater flow regime.
However, numerous water supply wells exist within a 4 mile radius of these sites and may have some
influence on gradient conditions recorded at the Site during these historical investigations. This
influence needs further characterization through analytical and/or numerical modeling efforts to
enhance understanding of past and present pumping well influence to plume migration and inform
institutional controls, if needed, to maintain protection of existing potable water supplies.

Section 3 • Physical Characteristics of the Site •
3.4 Surface Water Hydrology
There are two primary surface water features at the Site, Berwick Creek and Dillenbaugh Creek
(Figure 1-2). There are also two ditches with intermittent flows that discharge into Berwick Creek at
the HRIA. Both ditches pass under 1-5 and flow from east to west (Figure 2-1).
Berwick Creek flows through the HRIA from southeast to northwest, turns west at the Breen Property
and extends approximately 1,500 feet where it turns towards the north-northwest, meeting Dillenbaugh
Creek about 2,100 feet further. Berwick Creek drains into Dillenbaugh Creek, which flows into the
Chehalis River. Berwick Creek is classified as a Type F stream at the Site by the Washington State
Department of Natural Resources (DNR) [DNR 2010], A Type F stream is known to be used by fish or
meets the physical criteria to be potentially used by fish. Fish streams may or may not have flowing
water all year; they may be perennial or seasonal.
There are no use designations specifically for Berwick Creek in Ecology's Water Quality Standards for
Surface Waters of the State of Washington (WAC 173-201A-602, Table 602) (Ecology 2006). Ecology j
lists Berwick Creek as a Category 5 and 4A water body in the 2004 Water Quality Assessment 303(d) |
list (Ecology 2008) due to the exceedance of fecal coliform. j
Dillenbaugh Creek flows roughly southeast to northwest through the downgradient area of the Site.
Upstream of the confluence with Berwick Creek, Dillenbaugh Creek is classified as a Type F stream by
DNR. However, downstream of the confluence, the creek is classified as Type S. A Type S stream is
designated "shorelines of the state."
There are no use designations specifically for Dillenbaugh Creek in WAC 173-201A-602, Table 602.
Ecology lists Dillenbaugh Creek as a Category 5 and 4A water body in the 2004 Water Quality
Assessment 303(d) list (Ecology 2008). The creek is listed as a Category 5 water body due to an
exceedance of dioxin in fish tissue in a section of the creek downstream from the confluence with
Berwick Creek. The Category 4A listing is due to the exceedance of fecal coliform.
3.5 Surface Water and Groundwater Interaction
Surface water monitoring on Berwick Creek was conducted as part of the Breen RI/FS (Farallon 2003).
A comparison of surface water and groundwater elevations for corresponding monitoring points
measured in September and November 2002 indicated that surface water elevations were at or above
the potentiometric surface of the shallow aquifer during both events (Farallon 2003). These data
indicate that there is a potential for surface water to seasonally discharge to groundwater in areas where
the silt cap below the creek bed is thin or permeable. Data for surface water monitoring stations #5
through #10 are shown in Table 3-3. Station locations #1 through #4 apparently were not monitored.
Groundwater elevations in monitoring wells adjacent to Berwick Creek within the HRIA were above
the approximate surface water elevation (URS 2004) indicating a potential for groundwater to
seasonally discharge to surface water in this reach of Berwick Creek. However, at all exploration
locations near the creek, the silt cap of the shallow aquifer was found to be present between surface
water and groundwater. The low vertical hydraulic conductivity (6.3 x 10"7 cm/s) of the silt cap
probably minimizes the groundwater and surface water interaction within the HRIA. However, this low
conductivity value is based on bulk hydraulic conductivity measurements that do not include

Section 3 • Physical Characteristics of the Site •
conductivity which may be locally greater due to fracturing, scouring, or pathways formed by pre-
development vegetation roots.
The flow measurements at stations #5 through #10 in September and November 2002 were qualitatively
evaluated to determine whether Berwick Creek was losing or gaining water over the reach covered by
the surface water monitoring stations. September 2002 measurements (the end of the dry season)
recorded little to no flow at the majority of the stations with the exception of stations SW-8 and SW-9,
as shown in Table 3-3. Flows of approximately 500 and 870 gpm, respectively, were measured at these
two stations. November 2002 measurements showed flows of 1,400 gpm at station SW-8 and 1,250
gpm at station SW-9. Collectively, these measurements suggest the possibility that this reach of the
creek discharges groundwater as base flow (gaining) during the summer. However, the data are not
sufficient to make a quantitative assessment of summer base flow contribution.
3.6 Land and Groundwater Uses
The Site is located in a rural region used for agricultural activities. An estimated 1,200 people live
within four miles of OU1 and OU2 and have been identified by EPA as being within the potential area
for adverse effects from PCE contamination from groundwater (E&E 2000). The commercial district of
the City of Chehalis is located approximately 2 to 2.5 miles northwest of the Site.
OU1 and OU2 are located within the City of Chehalis' Urban Growth Area (UGA) and are zoned CG-
Commercial General. The Breen Property and United Rentals Property are used for commercial
purposes. A new freeway interchange was recently constructed on Labree Road; additional commercial
use is anticipated. Current land use downgradient (west) of Labree Road consists primarily of rural-
open (Class B Farmlands) and residential (Rural Development District [RDD]-20). A technical
memorandum, Revision 4 Final Hamilton/Labree Roads Land Use Evaluation (Parametrix 2008,
Updated by CDM 2011) further describes land use and is included in Appendix C.
Groundwater is used for drinking, cooking, bathing, irrigation, and stock watering by residences,
commercial businesses, and farms across the Site. Approximately 250 private water-supply wells are
located within four miles of the HRIA and the Breen Property (Farallon 2003).
Contaminated groundwater occurs in the shallow aquifer from approximately 5 feet to 50 feet bgs. The
shallow aquifer is used as a drinking water source for area residences not connected to the City of
Chehalis water system. As of July 2007, PCE had not been detected in any of the private wells in use at
residences not currently connected to the City of Chehalis water system.
3.7 Current Ecological Conditions
Potential ecological receptors for the Site are defined as animals (e.g., birds, mammals, fish) and plants
that inhabit or use, or have potential to inhabit or use, the aquatic and terrestrial habitats of the Site.
Birds such as the bald eagle, the American robin, and various ducks, such as the mallard, may visit the
Site. A wide range of mammals, including the short-tailed shrew, raccoon, and white-tailed deer, could
also frequent the Site.
URS (2004) conducted searches of wildlife databases and inquiries to regulatory agencies regarding
threatened and endangered species and environmentally important animals and plants to identify
receptors that are likely to be present in the Site vicinity and in Berwick Creek. Bald eagles (Haliaeetus
leucocephalus) were recently de-listed under the Federal Endangered Species Act (ESA). An eagle nest

has been documented approximately 1.25 miles southeast of the Site, near the Newaukum River. It is
possible that bald eagles in the area obtain food from Berwick Creek.
The only species of special concern that utilizes certain reaches of Berwick Creek is the Coho salmon
(Oncorhynchus kisutch). Berwick and Dillenbaugh Creeks are designated as essential fish habitat for
the Coho and Chinook salmon (Oncorhynchus tschawytscha) under the Magnuson-Stevens Act.
Berwick Creek was identified as having Coho salmon spawning and rearing habitat in the lower
reaches, which would include areas both downstream and upstream of the HRIA.

Section 4
Nature and Extent of Contamination
This section provides information on the nature and extent of contamination by release/source
areas and by media of concern based on investigations described in Section 2. The evaluation
focuses mainly on the HRIA. Although the Breen Property, the Thurman Berwick Creek
Area, and the downgradient areas west of Labree Road have not been fully characterized, the
available information for these areas is included to provide a better understanding of Site-
wide groundwater contamination, especially contamination attributable to the HRIA.
Historical sampling results and data used to assess the nature and extent of contamination
across the Site are summarized in Tables 2-2 through 2-11 and Appendix A. As summarized
in the Data Usability Review Technical Memorandum, all data were determined to be of
sufficient quality to support the delineation of potential contamination (Parametrix 2008).
The Data Usability Review Technical Memorandum is provided in Appendix C. The
locations of all sampling points are shown on Plates 1, 2, and 3 in Appendix B. Sampling
points at and adjacent to the HRIA and the Breen Property are also shown on Figures 2-1 and
2-2, respectively.
4.1 Contaminants of Potential Concern
Based on previous investigations, the COPCs across the Site are PCE and its degradation
products TCE, cis-1, 2-DCE, and vinyl chloride, as well as the chemicals tetrahydrofuran and
methylene chloride. TPHs are also considered to be a presumptive COPC until proven
otherwise.
PCE has been detected more frequently and at much higher concentrations than the other
COPCs, and it is the primary risk driver according to the baseline risk assessment (BRA)
(Section 6). Therefore, contaminant discussions for the Site focus on PCE as the indicator or
primary COPC.
4.2 Possible Source Areas
There are two areas where releases of hazardous wastes are known to have occurred at the
Site: the HRIA and the Breen Property. A third apparent PCE source area at the Site is the
Thurman Berwick Creek Area. There are no known PCE source areas west of Labree Road.

Section 4 • Nature and Extent of Contamination •
4.2.1 HRIA
The primary contaminant at the HRIA is the result of an apparent spill or dumping of PCE into Berwick
Creek that apparently occurred just upgradient of where the Unnamed Ditch #1 enters Berwick Creek.
Based on the observed extent of the plume in 1993 and a groundwater seepage velocity of 0.36 ft/day,
the spill is estimated to have occurred sometime before 1990 (URS 2004, page 2-18). High
concentrations in a localized area strongly point to a single release at this location, but multiple releases
may have occurred along a 400-foot reach of Berwick Creek, as possibly indicated by high PCE
concentrations identified in an area referred to as the "Northwestern Hot Spot", which begins
approximately 80 feet downstream of Unnamed Ditch #1. The estimated volume of the release is
between 100 and 700 gallons (URS 2004). Some breakdown compounds of PCE are present, including
TCE and cis-l,2-DCE, but at much lower concentrations than PCE and with a much lower frequency of
detection. Thus, the primary contaminant at the HRIA is PCE, and there is no evidence that PCE was
mixed with any other contaminant.
4.2.2 Breen Property j
The groundwater contamination at the Breen Property appears to be related to multiple releases related to |
operations by Breen between the early 1960s and early 1990s. In September 1999, sixty-six 55-gallon j
drums, four 30-gallon drums, and a number of pails and cans were removed from beneath Building B on f
the Breen Property. Since that time, no other sources of contamination to groundwater have been found.
However, there appear to be several additional areas of contamination on the Breen Property that may be
actively contributing to groundwater contamination.
4.2.3 Thurman Berwick Creek Area
The results of groundwater sampling conducted in the areas downgradient of the HRIA and south of the
Breen Property indicate the presence of a potential source within or upgradient of the Thurman Berwick
Creek Area (Figure 4-2).
4.2.4 Downgradient Areas West of Labree Road
The groundwater contamination downgradient of Labree Road is primarily related to known or potential
sources at the HRIA, the Breen Property, or the Thurman Berwick Creek Area.
4.3 Soils
PCE in soils can be divided into three categories: surface, near surface and subsurface. In general,
surface soils at the Site are defined as 0 to 5 feet bgs and near surface soils as 5 to 10 feet bgs.
Subsurface soils are at depths greater than 10 feet and are typically below the silt cap. Subsurface soil
samples from the Site have typically been collected between 10 to 50 feet bgs, the top of the aquitard.
Surface/near surface and subsurface soil sampling results are summarized in Table 2-2 and Appendix A,
Tables A-l and A-2.
4.3.1 Surface and Near Surface Soils
Currently, the only identified surface and near surface soil source that contributes PCE to groundwater is
creek bed sediment/soil in the HRIA. Only minor surface soil contamination has been identified at the
Breen Property and in downgradient areas.

-------
Section 4 • Nature and Extent of Contamination •
4.3.1.1 HRIA
PCE in surface and near surface soil was detected at the HRIA at a maximum concentration of 678
mg/kg at GP-501 at a depth of 5 feet bgs just below the base of the silt cap. This sample was collected in
the area of the highest PCE concentrations in groundwater south of MW-602.
4.3.1.2 Breen Property
Few surface (0 to 5 feet bgs) and near surface (5 to 10 feet bgs) soil samples were analyzed on the Breen
Property. Soil samples were sometimes collected during installation of reconnaissance borings and
groundwater monitoring wells, but these were usually subsurface soil samples (greater than 10 feet bgs).
PCE contamination at the Breen Property may be primarily related to subsurface sources (i.e., buried
drums at Building B and the collection pit at the wash-down area). Only one sample, SP-1, located near
the wash-down pad, was collected near the surface at a depth of 2.5 feet bgs. Available surface and near
surface soil data collected in the areas of Building B and the wash-down pad showed little to no PCE or
other VOCs at concentrations above laboratory detection limits or practical quantitation limits (PQLs). |
In general, the laboratory detection limits were below applicable MTCA Method A and B cleanup levels j
(Ecology 2007a). It is noteworthy that the laboratory detection limit for PCE for confirmation, SP, and )
test pit (TP) samples collected at Building B, and samples collected around the wash-down pad,
however, were at or above Ecology's MTCA Method A cleanup level of 0.05 mg/kg for residential and
industrial sites.
4.3.1.3 Thurman Berwick Creek Area
No surface or near surface soil samples collected from the Thurman Berwick Creek Area had detectable
PCE concentrations.
4.3.1.4 Downgradient Areas West of Labree Road
No surface or near surface soil samples collected west of Labree Road had detectable PCE
concentrations. However, the only surface or near surface soil samples were collected from borings
along road right-of-ways, not from likely source areas.
4.3.2 Subsurface Soils
4.3.2.1 HRIA
The highest PCE concentrations in subsurface soil at the HRIA appear to be directly related to PCE
DNAPL, based on a threshold calculation of 38 mg/kg (URS 2004). PCE concentrations high enough to
indicate the presence of DNAPL have been observed in subsurface soils beneath the apparent PCE
release in Berwick Creek. The highest PCE concentration in soil, 3,220 mg/kg, was detected at GP-502
at a depth of 28 feet bgs (Figure 2-1). In general, the highest PCE concentrations were found at MW-9,
MW-602, GP-501, GP-502, GP-503, and AB-650, which are all located along the banks of Berwick
Creek.
4.3.2.2 Breen Property
Minor concentrations of PCE have been detected in subsurface soils at the Breen Property. Soil
contamination related to leakage from drums buried beneath Building B was removed during the
remedial action to remove the drums in 2001.

-------
Section 4 • Nature and Extent of Contamination •
Two previous investigations conducted by SAIC (1997) and Farallon (2003) examined soil
contamination at depths between 10 and 50 feet. Results indicate that soil contamination was minimal.
PCE concentrations at more than half of the sampling locations were non-detect. The highest PCE
concentration was recorded at a depth of 43 feet bgs in RS-16 (0.16 mg/kg) located along the western
property line.
4.3.2.3 Thurman Berwick Creek Area
Subsurface soil sampling data for the Thurman Berwick Creek Area are limited. PCE has been detected
in soil at four locations: MW-23, MW-24, RS-30, and RS-31. The highest PCE concentration was
detected in RS-31 (1.3 mg/kg) between 14 and 15.5 feet bgs.
4.3.2.4 Downgradient Areas West of Labree Road
Soil data are available for one sampling location west of Labree Road (MW-25). Soil samples were
collected from this boring at three depths: 5 to 6.5 feet bgs, 10 to 11.5 feet bgs, and 39 to 40 feet bgs.
PCE was only detected in the 39 to 40 feet bgs sample at a concentration of 0.13 mg/kg.
4.3.3 Extent of PCE in Soil at the HRIA
Soil isoconcentration contour maps were produced based on sampling completed at the HRIA during the
EE/CA investigations (URS 2004). These maps show the concentration of PCE in soil at 5-foot intervals
between 0 to 55 feet bgs. URS identifies the depths as between elevations 210 feet (surface) and 155
feet (near the silt and clay aquitard). The silt and clay aquitard was encountered from 45.5 feet bgs to 49
feet bgs in three borings and 8 wells advanced in the HRIA by URS at the depths necessary to penetrate
this feature.
The isoconcentration maps show that no PCE occurs in the upper 5 feet of soil outside of Berwick Creek.
In fact, PCE outside of the source area appears to be associated with saturated soils, or at shallowest,
capillary zone soils. PCE as DNAPL is generally not found in soil below 35 feet bgs except in MW-9
where DNAPL was found as deep as 43 feet bgs. PCE is present in deeper soils, but concentrations
generally decline with depth and do not suggest the presence of DNAPL at the silt and clay aquitard.
Copies of the soil isoconcentration maps are included in Appendix D.
4.3.4 Other Soil Analyses
Soil samples collected during the HRIA EE/CA investigations were analyzed for a variety of physical
characteristics and metals. The results of these analyses are summarized in Tables 2-9 and 2-10. Soil
samples collected during drum and associated contaminated soil removal at the Breen Property were also
analyzed for TPH-G and total petroleum hydrocarbons quantified as diesel (TPH-D) using NWTPH-Gx
and NWTPH-Dx, respectively. The purpose of these samples was to assess the completeness of
contaminated soil removal during cleanup activities. Results for the soil sampling are summarized in
Appendix A, Table A-2.
4.4 Groundwater
This section discusses the nature and extent of PCE in groundwater at the HRIA, the Breen Property, and
other areas of the Site. PCE, TCE, and cis-l,2-DCE data are summarized in Table 2-3, and other
groundwater analytical data are summarized in Appendix A, Tables A-3 and A-4.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11

-------
Section 4 • Nature and Extent of Contamination •
The PCE plume in the shallow aquifer appears to be stratified over much of the Site. Although, this
stratification needs further characterization, it is believed to be influenced by horizontal groundwater
flow and the propensity for PCE to sink. For the purposes of this RI, the upper zone of the shallow
aquifer refers to the portion at or above 25 feet bgs and the lower zone is the portion below 25 feet bgs to
the top of the silt and clay aquitard. The 20- to 30-foot zone appears to be a transition or mixing zone
often characterized by intermediate concentrations. The deep aquifer below the aquitard has not been
fully characterized. No monitoring wells have been installed within the deep aquifer. Minor amounts of
PCE have been detected in samples collected from private wells screened in the deep aquifer but not
enough to suggest significant migration of PCE through the aquitard. Section 4.4.5 discusses sampling
results in the deep aquifer.
4.4.1 HRIA
The groundwater sampling results indicate that there are two distinct areas of groundwater contamination
within the HRIA. For the purposes of this discussion, these areas are referred to as the Southeastern Hot
Spot and Northwestern Hot Spot (Figure 4-1).
The Southeastern Hot Spot at the HRIA is located in the area of monitoring wells MW-600 through
MW-604, beneath the assumed PCE release location into Berwick Creek. PCE concentrations in
groundwater were detected up to 2,720,000 |a,g/L at MW-602 in November 2003, which is greater than
the solubility limit of PCE. PCE concentrations potentially indicative of DNAPL (exceeding 10% of
solubility limit or 20,000 |a,g/L PCE) were detected in groundwater and subsurface soils ranging from
just beneath the silt layer in the bed of Berwick Creek to 32 feet bgs.
The Northwestern Hot Spot is centered on monitoring well MW-R4 where PCE concentrations of 5,300
(ig/L and 8,800 (ig/L were detected in groundwater samples collected in February and November 2003,
respectively. Dissolved PCE in groundwater appears to have migrated northwest of the Northwestern
Hot Spot based on data collected by Farallon (Farallon 2004). A groundwater sample at MW-33, located
west of the Northwestern Hot Spot, contained PCE at 1,100 |a,g/L in April 2004.
Both the Southeastern and Northwestern Hot Spots suggest stratification of PCE in groundwater within
the shallow aquifer that is characterized by higher concentrations of PCE in those monitoring wells
screened in the upper zone of the shallow aquifer. Multi-level groundwater sampling was conducted in
November 2002 (Farallon 2003) at monitoring wells MW-R8 and MW-R11, both of which are fully
penetrating wells within the aquifer, by setting the pump at different depths. Multi-level sampling was
conducted to qualitatively assess the potential stratification of the PCE plume in groundwater at the
Southeastern Hot Spot and the area immediately downgradient. Results at monitoring well MW-R8
showed significantly higher PCE concentrations in the upper zone as compared to the lower zone. PCE
ranged from 4,700 (ig/L at 15 feet bgs to 360 (ig/L at 48.5 feet bgs. Multi-level sampling in monitoring
well MW-R11 did not indicate a significant variation in PCE concentrations in groundwater samples
collected at varying depths between 26 and 48.5 feet bgs. However, PCE concentrations were relatively
low at approximately 25 (ig/L. Multi-level samples were also collected from all of the MW-600-series
wells when they were installed in October/November 2003. The most dramatic stratification was

observed in MW-602, which had 2,720,000 (ig/L in the 14.5-foot sample, 203,000 (ig/L in the 35-foot
sample, and 4,980 (ig/L in the 41-foot sample.2
Dissolved PCE in groundwater at concentrations greater than 1,000 |a,g/L originating from the HRIA is
typically found in the lower zone of the shallow aquifer downgradient of the United Rentals Property.
However, as shown on the groundwater PCE isoconcentration map produced from 2007 data
(Figure 4-2), dissolved PCE in groundwater at concentrations greater than 1,000 |a,g/L originating from
the HRIA does not appear to have migrated west of the Thurman Berwick Creek Area. PCE at
concentrations less than 1,000 |a,g/L has migrated farther downgradient and has commingled with the
PCE plume originating from the Breen Property and an apparent PCE plume originating from or just
upgradient of the Thurman Berwick Creek Area.
Over much of the area between United Rentals and the Breen Property wash-down pad and the Thurman
Berwick Creek Area, the upper zone of the shallow aquifer is non-detect for PCE over a north-south
section stretching from RS-2 to RS-24 (Figures 4-2 and 4-6). Further north, some shallow
contamination (maximum 400 (ig/L) is found in the RS-1 area on the Breen Property approximately 50 |
feet north of RS-2. This area of low to no PCE concentration is termed the "bottleneck" because of its J
shape. There may be some lithologic and/or hydraulic explanation for this, but currently there is |
insufficient lithologic and groundwater information in the area to provide a basis for the anomaly at this j
time. It may be a feature resulting from limited data in the area and thus the need to explore it with
additional borings/wells is described in the Study Limitations Analysis memorandum (Appendix C). It
is possible that with additional investigation in this area, the "bottleneck" will disappear, or shrink
considerably.
4.4.2 Breen Property
In September 1999, approximately 70 drums and other containers and 600 tons of PCE and petroleum
contaminated soil were removed from beneath Building B on the Breen Property. Confirmation sampling
results for soil samples collected from the final excavation were either non-detect or contained
contamination below MTCA Method A and/or Method B cleanup levels (GeoEngineers 2001).
Since that time, no other sources of contamination to groundwater have been identified. However, based
on groundwater analytical data, several additional areas of soil contamination on the Breen Property
appear to be contributing sources to groundwater contamination (EPA 201 lb). The exact locations have
not been identified but may include the following areas:
Area surrounding the wash-down pad
Area between Building B and Building C, including:
The area upgradient of monitoring well MW-27, and
Torpedo Tube area
Area surrounding Building B
2 Stratification within the shallow aquifer needs further characterization due to limited information available
regarding the protocols followed for the multi-level sampling effort. Thus, inconsistencies with pump installation,
sample interval sequencing, and low-flow pumping rates may be present and reduce certainty of these results.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11

-------
Section 4 • Nature and Extent of Contamination •
Wash-Down Pad and Surrounding Area
The wash-down pad, located near the southwest corner of the Breen Property, has been the subject of
several investigations (GeoEngineers 2001; Farallon 2003). Based on historical accounts, waste from
steam cleaning conducted at the wash-down pad was collected in an approximately 5-foot deep pit
located adjacent to the pad. The exact location of this pit is unknown.
Historically, groundwater samples collected from the upper zone of the shallow aquifer at SG2-15, MW-
34, and RS-7, located immediately upgradient of the wash-down pad, contained PCE concentrations of
1,500 (ig/L, 1,700 (ig/L, and 2,400 (ig/L respectively. Groundwater samples collected from MW-29,
located 100 feet upgradient of the wash-down pad, had much lower PCE concentrations in November
and September 2003. Upper zone well MW-29 contained PCE at concentrations ranging from 19 to 140
(ig/L. The relatively higher concentrations of PCE in the upper zone of the shallow aquifer adjacent to
the wash-down pad, compared to PCE concentrations further upgradient of the wash-down pad, indicate
a suspected source of PCE to groundwater at or immediately upgradient of the wash-down pad area.
Between Building B and Building C
Area Upgradient of MW-27: Groundwater samples collected in the area between Building C and the
Torpedo Tube (Figure 2-2) indicate a potential source of PCE. In July 2002, the maximum PCE
concentration detected in the lower zone of the shallow aquifer in boring RS-11 was 880 (ig/L, and the
maximum concentration in the lower zone in boring RS-16, located 100 feet downgradient of RS-11,
was 620 (ig/L. September and November 2003 results showed PCE concentrations in lower zone well
MW-27, located immediately north of the northeast corner of Building C and upgradient of RS-16,
ranging from 1,300 (ig/L to 1,500 (ig/L. In contrast, the maximum PCE concentration detected in the
lower zone in RS-1, located upgradient and approximately 400 feet east of MW-27, was 260 (ig/L at a
depth of 30 feet bgs, followed by 84 (ig/L at a depth of 46 feet bgs. Since that time, no sampling has
been completed immediately upgradient of MW-27 or in the area between MW-27 and RS-1.
PCE was also detected in the upper zone in borings RS-1 (400 j^ig/L) and RS-11 (310 (ig/L). suggesting a
possible upper zone source near RS-1 that may account for some of the contamination in this area. In
addition, a 1969 aerial photograph of the Breen Property shows a possible trench containing debris or
drums roughly 100 feet east and upgradient of MW-27. The area containing this trench does not appear
to have been part of a 1996 GeoRecon geophysical investigation or the 2000 GeoPotential investigation
conducted at the Site.
A metal cover was observed in the area of MW-27 in July 2007. What this object covers is unknown and
will require further evaluation to determine if it could be associated with a potential source of
groundwater contamination.
Torpedo Tube Area: A geophysical investigation conducted by GeoPotential in 2000 covered several
areas of the Breen Property, including the area southwest of the Livestock Shed, Building B, and the
wash-down pad area. Several geophysical anomalies were identified during this investigation, including
the Torpedo Tube (GeoPotential 2000) (see Section 2.6 for further discussion of the Torpedo Tube). The
original reports that outline the entire geophysical survey areas appear to be lost. Figure 2-2, which
indicates geophysical survey areas, appears to be the areas where anomalies were identified.
In 2002, Farallon completed a boring (RS-9) adjacent to the Torpedo Tube, and PCE in groundwater was
detected at 250 (ig/L in the lower zone, but was non-detect in the upper zone (Farallon 2003). A sample

Section 4 • Nature and Extent of Contamination •
collected in 2002 in RS-5, approximately 100 feet upgradient of the Torpedo Tube, contained PCE at 77
(ig/L in the lower zone. Groundwater samples collected from the lower zone in boring RS-15A, located
west and downgradient of the Torpedo Tube near the Breen Property boundary, contained PCE at
concentrations of 1,100 (ig/L at 32 feet bgs and 1,300 (ig/L at 43 feet bgs. Groundwater samples
collected from lower zone well MW-19, located near RS-15A, contained PCE at concentrations of 1,600
(ig/L in 2002 (maximum concentration detected), 1,400 (ig/L in February and November 2003, and
1,400 (ig/L in July 2007. These concentrations are significantly higher than those detected at boring RS-
16, located 100 feet south and cross-gradient of MW-19. PCE at RS-16 ranged from 420 (ig/L to 620
(ig/L in the lower zone samples collected in 2002. These results indicate a potential PCE source between
Building C and the Torpedo Tube. The PCE source for this groundwater contamination has not been
identified and no sampling has been completed immediately downgradient of the Torpedo Tube to
determine whether it is a potential source for the PCE detected at RS-15A and MW-19.
Building B
As stated earlier, a cleanup was conducted in 1999 under Building B to remove drums identified by a (
|
ground-penetrating radar survey (GeoEngineers 2001). Groundwater sampling conducted in July 2002 in |
areas downgradient of Building B at RS-8, RS-13, and RS-14 contained PCE and its degradation j
products, including cis-l,2-DCE. Similarly, cis-l,2-DCE was detected in samples collected from
monitoring well pair MW-17/MW-18, located directly downgradient of Building B in 2002 and 2003.
PCE was detected in shallow zone well MW-17 at a maximum of 2.4 j^ig/L: however, the maximum cis-
1,2-DCE concentration was 510 (ig/L. PCE was detected in deep zone well MW-18 at a maximum of
88.6 (ig/L, with a maximum cis-l,2-DCE concentration of 9.4 (ig/L. Both of these wells were installed in
2002, so changes in groundwater contaminant levels as a result of remedial efforts cannot be assessed.
The PCE concentrations are similar to those in upper and lower zone groundwater samples from
temporary well points SP-5 through SP-8 collected in 1999.
November 2007 air sampling conducted in and under Building B found PCE. This may suggest a source
of contamination to groundwater under or around Building B. The highest concentration of PCE was
detected at 120 micrograms per cubic meter (|ig/m3) in a subslab sample collected in the main bay of
Building B. The next highest concentration of 70 (ig/m3 of PCE was detected in a subslab sample
collected in the office of Building B.
Other Areas
Other potential sources may exist at the Breen Property, including a possible area upgradient of RS-6
(-700 (ig/L PCE), located approximately 140 feet east of Building C. Several other areas had PCE
concentrations in groundwater exceeding 200 (ig/L, including an area west of the Livestock Shed. Soil
and groundwater investigations were conducted in this area of geophysical anomalies (shown as
geophysical survey areas GA-1 and GA-2 on Figure 2-2) by Farallon (2003); no source for this
contamination was identified.
In 2007, PCE was detected in MW-21 at 1,500 (ig/L and in MW-30 at 1,300 (ig/L. Both locations are
situated near the southern property line of the Breen Property. MW-21 is located in the southwest corner
of the property and MW-30 is located east of the wash-down pad. Both of these wells are screened in
the lower zone of the shallow aquifer. The concentrations are comparable to 2003 results. Up to about
1,000 (ig/L of the PCE in MW-30 is likely from the HRIA. The source for the additional contamination
at MW-30 is not known, but could include a potential release to Berwick Creek immediately upgradient
of this well.

Section 4 • Nature and Extent of Contamination •
4.4.3 Thurman Berwick Creek Area
Groundwater sampling results in the areas downgradient of the HRIA and south of the Breen Property
suggest the presence of a potential source within or upgradient of the Thurman Berwick Creek Area
(Figure 4-2).
PCE concentrations up to 3,740 (ig/L have been detected in groundwater samples collected from private
well PW-9, located adjacent to the Thurman residence. There is no log for this well so the screened
interval is unknown. However, PCE has been detected in upper zone monitoring wells in this area at
concentrations up to 2,700 (ig/L and in lower zone monitoring wells up to 2,000 (ig/L. No source for the
high concentrations of PCE in groundwater in the Thurman Berwick Creek Area wells has been
identified. None of the PCE in the upper zone and concentrations less than 1,000 (ig/L in the lower zone
can be attributed to the HRIA source. A possible source for the contamination includes a potential
release to Berwick Creek where it turns south from the Breen Property. A release would have migrated
through the creek bed and to the shallow aquifer. Alternatively, PCE disposal may have occurred in the
area between the MW-22/23/24 well line and Berwick Creek (Figure 4-2). j
PCE isoconcentration contour maps based on groundwater data for the Site show that the 1,000 (ig/L J
contour from the HRIA in the lower zone of the shallow aquifer bifurcates into a northern and a southern !
lobe (Figure 4-7). The southern lobe does not appear to extend to the Thurman Berwick Creek Area, and (
little or no shallow contamination (less than 25 feet deep) from the HRIA extends to wells MW-22 or
RS-19. This would indicate a potential local PCE source upgradient of PW-9, at or upgradient of
Berwick Creek as indicated by high concentrations in upper zone wells MW-31 (2,300 (ig/L) and MW-
32 (2,700 (ig/L), as well as in borings RS-31 (1,700 (ig/L at 18 feet) and RS-33 (1,400 (ig/L at 18.5 feet).
These concentrations may be associated with a PCE release to Berwick Creek south of the Breen
Property or migration of PCE contamination from another source within the Site. The PCE source for
this groundwater contamination has not been identified.
4.4.4 Downgradient Areas West of Labree Road
Only a few sampling points exist in the shallow aquifer immediately downgradient of Labree Road, and
both are 200 to 300 feet downgradient of PW-9 in the Thurman Berwick Creek Area. PCE has been
detected in private well PW-7 at concentrations ranging from 140 to 980 (ig/L. No well log exists and
the depth of this well is unknown. It is unclear what aquifer zone these concentrations represent. In
boring B-l 1, located 70 feet west of PW-7, PCE was detected at 1,730 (ig/L in the upper zone and 970
(ig/L in the lower zone of the shallow aquifer.
Private well PW-21, located on Rice Road, was non-detect for PCE (<1 j^ig/L) in 1999 and had a
detection of 4.6 (ig/L of PCE in 2001. The PCE concentration has subsequently been close to or slightly
above 5 (ig/L. Because PW-21 is located on the southern edge of the plume, it may record the arrival of
contamination from the HRIA that had previously been pulled south by the former production wells (see
Section 3.3) located south of the HRIA and the Thurman Berwick Creek Area. Alternately, it may be
associated with another potential source located upgradient of PW-21.
Three transects of borings and two monitoring wells have been installed in the general downgradient
direction from the Breen and Thurman Berwick Creek Properties (Plates 1 through 3 in Appendix B).
The first two transects were installed neither perpendicular nor parallel to the plume. The third transect
was installed roughly perpendicular to the plume. The second transect sampled only the lower zone of
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11

Section 4 • Nature and Extent of Contamination •
the shallow aquifer, whereas both the upper and lower zones of the shallow aquifer were sampled in the
first and third transects.
PCE in the first transect was highest in the upper zone in RS-48 (about 1,200 feet downgradient of the
wash-down pad area) at 630 (ig/L. In contrast, the highest concentration in the lower zone was 910 (ig/L
in RS-49, about 500 feet south of RS-48 and about 900 feet downgradient of the Thurman Berwick
Creek Area.
Along the second downgradient transect, PCE concentrations in lower zone well MW-25 (2,200 feet
northwest of the nearest contaminated well along Labree Road) ranged from 600 (ig/L to 760 (ig/L. The
maximum concentration in boring RS-20 (500 feet farther downgradient and to the north) was 890 (ig/L,
suggesting that MW-25 was not installed along the centerline of the plume (Figure 4-3).
Along the third and most downgradient transect, PCE concentrations in MW-28 (another 3,800 feet in
the general downgradient direction from RS-20, and screened across portions of both the upper and
lower zones) has been non-detect at the laboratory reporting limit (<0.2 (ig/L) except for one detection of
0.35 (ig/L. PCE concentrations in groundwater samples collected at multiple depths in nearby borings |
RS-41, RS-42, and RS-43 were all non-detect at the laboratory reporting limit (<0.2 (ig/L). The plume j
may not yet have reached these sampling points, or the plume may turn more northerly, perhaps
discharging to Dillenbaugh Creek somewhere between RS-20 and MW-28.
4.4.5 Extent of Groundwater PCE Contamination
Vertical Extent in the Shallow Aquifer
Cross-sections, which included the vertical extent and concentrations of PCE in groundwater, were
prepared for the HRIA (URS 2004) and are included in Appendix D. These cross-sections indicate that
the PCE DNAPL at the HRIA may have migrated vertically through the aquifer 30 to 35 feet, but has not
reached the silt and clay aquitard beneath the shallow aquifer.
Cross-sections prepared by Farallon cover portions of the Breen Property and the Thurman Berwick
Creek Area (Appendix D).
A conceptual cross-section down the centerline of the plume from the HRIA through the southwestern
portion of the Breen Property and Thurman Berwick Creek Area to RS-20 shows how and where
contamination from the different PCE sources migrates and mixes in the shallow aquifer (Figure 4-4). A
conceptual cross-section transecting the plume at the low PCE concentration area between the HRIA and
the Thurman Berwick Creek Area is shown on Figure 4-5. These conceptual cross-sections interpolate
data where data are plentiful; however, in the downgradient areas, little data are available so apparent
concentration trends are extrapolated conservatively.
Horizontal Extent in the Shallow Aquifer
Isoconcentration contour maps were prepared to illustrate the horizontal extent of the PCE plume in the
vicinity of the HRIA and across the Site. Groundwater sampling data collected in November 2003 during
the Phase II RI/FS sampling (Farallon 2004), the HRIA EE/CA investigation (URS 2004), and the July
2007 sampling conducted by Parametrix were used. Data included primarily groundwater analytical
results from monitoring wells, but additional data from discrete sampling points were used to fill data
gaps in areas without monitoring wells.

Section 4 • Nature and Extent of Contamination •
Figure 4-2 shows the PCE isoconcentration contours for the HRIA in July 2007. The 1,000 (ig/L PCE
contour from the HRIA bifurcates into a northern and a southern lobe. The northern 1,000 (ig/L PCE
lobe appears to originate in the HRIA's Northwestern Hot Spot where the upper zone of the shallow
aquifer shows higher PCE concentrations relative to the lower zone. This lobe extends under North
Hamilton Road along the southern boundary of the Breen Property and barely reaches the southwest
corner of the Breen Property and the northernmost portion of the Thurman Berwick Creek Area (based
on the 1,200 (ig/L detection in the deepest sample from boring RS-46). The southern 1,000 (ig/L lobe
appears to originate in the HRIA's Southeastern Hot Spot where the upper zone of the shallow aquifer
shows higher PCE concentrations relative to the lower zone. This lobe almost extends to the Thurman
Berwick Creek Area.
Figure 4-3 shows the regional (Site-wide) PCE isoconcentration contours in July 2007. After crossing
under Labree Road, the plume turns in a north-northwesterly direction, essentially following Berwick
and Dillenbaugh Creeks. Currently, this turn to a north-northwesterly direction is only supported by two
well sampling/gradient points (MW-25 and MW-28). However, the north-northwest gradient of the local
topography and surface water flow in shallow creeks discharging to the Chehalis River further supports |
this direction of groundwater flow and subsequent plume migration. J
Figure 4-6 shows the maximum concentrations detected at sampling points in the upper zone of the
shallow aquifer. A lobe of the PCE plume in the upper zone (with concentrations less than 500 (ig/L)
may extend from the northern end of the HRIA to the southwestern corner of the Breen Property. Or,
since this northern PCE upper zone lobe runs somewhat north of and parallel to the HRIA 1,000 (ig/L
PCE northern lower zone isoconcentration contour, it may have a separate source on the Breen Property.
Figure 4-7 shows the maximum concentrations detected at sampling points in the lower zone of the
shallow aquifer. The pattern is similar to Figure 4-2, confirming that most of the contamination
downgradient of the HRIA occurs in the lower zone of the aquifer.
There is some indication that the plume from the HRIA has continued to advance. Groundwater
concentrations in both lower zone 1,000 (ig/L PCE plume lobes downgradient of the HRIA (but
upgradient of the Thurman Berwick Creek Area and the southwest corner of the Breen Property)
generally increased between 2003 and 2007. The lower zone PCE concentration in MW-4 showed an
increase from 700 (ig/L to 900 (ig/L between November 2003 and July 2007. MW-23 showed an
increase in lower zone PCE concentration from 680 (ig/L to 870 (ig/L (Figure 4-7 and Plate 1). These
increases in PCE indicate advancement of the higher concentration plume lobes from the HRIA and that
the HRIA source is not in dynamic equilibrium with the groundwater.
Although the HRIA source area continues to generate a high concentration PCE plume, there are
apparent constraints on how much contamination reaches the areas downgradient of the HRIA source
areas. A north-south zone east of where North Hamilton Road crosses Berwick Creek, between RS-2 and
RS-24, appears to act as a vertical PCE "bottleneck," preventing significant transport of PCE in the
upper zone of the shallow aquifer from the HRIA to the Breen Property and the Thurman Berwick Creek
Area. Some shallow contamination (maximum 400 (ig/L PCE) is found in the RS-1 area on the Breen
Property approximately 50 feet north of RS-2. It is unknown if the source is local (on the Breen
Property) or whether it is from the HRIA, perhaps the Northwestern Hot Spot. Gradient directions may
be different in the upper and lower zones of the shallow aquifer to account for this variation in
contaminant migration. In addition, a vertical gradient may also be prevalent between the upper and
lower zones, which drives contaminants to the lower zone. Additional depth-discrete gradient data is

Section 4 • Nature and Extent of Contamination •
needed to confirm transport in the upper and lower zones of the shallow aquifer between the HRIA and
the Breen Property and Thurman Berwick Creek Area.
The upper zone of the shallow aquifer within the "bottleneck" area has very little PCE contamination
(Figures 4-2, 4-4 and 4-6) suggesting that very little of the PCE contamination in the upper zone of the
shallow aquifer west of this north-south section (including the Breen Property wash-down pad and the
Thurman Berwick Creek Areas) could have come from the HRIA. PCE concentrations in the lower zone
of the shallow aquifer in the Thurman Berwick Creek Area reflect mixing between upgradient Berwick
Creek sources and a limited amount of lower zone groundwater contamination from the HRIA. The
contribution from the HRIA would generally appear to be limited to approximately 1,000 (ig/L in the
lower zone of the shallow aquifer in the Thurman Berwick Creek Area, as indicated by the PCE
isoconcentrations maps (Figures 4-2 and 4-7) and as shown by the conceptual plume centerline figure
(Figure 4-4). Regardless of the age of the HRIA source, these apparent constraints on PCE migration in
groundwater to the Breen Property and Thurman Berwick Creek Area suggest that the proportion of
contamination from the HRIA that has continued to migrate downgradient from Labree Road is perhaps
25 to 30 percent, and almost entirely in the lower zone of the shallow aquifer (Figure 4-3). However, a |
full mass flux/discharge evaluation would need to be conducted within the upper and lower zones of the !
shallow aquifer to determine the contribution from the HRIA to the Thurman Berwick Creek Area and j
Breen Property.
The source areas at the Breen Property and the Thurman Berwick Creek Area appear older and less
concentrated than the HRIA source. However, PCE increases at these locations, especially in the upper
zone, and to some extent in the lower zone, exceed the concentrations of PCE in the plume attributable
to the HRIA as it reaches these new sources (Figures 4-6 and 4-7). Thus, the majority of the
downgradient groundwater plume west of Labree Road most likely originated from sources at the Breen
Property and the Thurman Berwick Creek Area. However, as noted early, a mass flux/discharge
evaluation would need to be conducted for the HRIA, Breen Property, and Thurman Berwick Creek Area
to determine the actual contributions from each source area to the plume.
Although the full extent of the Site-wide plume is not currently known, it has migrated a minimum of
3,000 feet downgradient from the Breen Property west of Labree Road. Based on groundwater flow
calculations, the shallow aquifer plume emanating from the HRIA may have migrated only about 1,500
to 2,000 feet, or to roughly 500 feet west of Labree Road, assuming that the HRIA disposal did not occur
much before 1990. PW-3, located approximately 400 feet from the Southeastern Hot Spot, was found to
be contaminated in 1993. Using the EE/CA groundwater seepage velocity of 0.36 foot/day and not
considering contaminant retardation, the release in Berwick Creek likely happened at least 3 years prior
to sampling in 1993. The latest possible release time is, therefore, 1990. If retardation is considered, the
actual release time could be earlier (URS 2004 page 2-18).
Deep Aquifer
The deep aquifer has never been specifically characterized and no monitoring wells have been installed.
A few private wells are completed in the deep aquifer across the Site (Figure 1-3 and Table 3-5). Minor
amounts of PCE have been detected in some deep aquifer wells, but not enough to suggest significant
migration of PCE through the silt and clay aquitard. The fact that PCE has been detected in the deep
aquifer may indicate minor PCE migration from the shallow aquifer has occurred along well casings, but
not all of the detections have been from wells located within the shallow aquifer plume. For example, in
2002, PCE was detected at 0.73 (ig/L in private well PW-23, 500 feet south of the HRIA and outside the

Section 4 • Nature and Extent of Contamination •
shallow aquifer plume. However, PCE was not detected in PW-23 during sampling events conducted in
2001 and 2003.
PCE was detected at 0.39 (ig/L in a 2002 sample collected from private well PW-1 located near the
middle of the Breen Property. However, the associated field duplicate was below the laboratory
detection limit for PCE, and PCE was not detected in five other sampling events between 1993 and 2003.
PCE has never been detected in any of five rounds of sampling at PW-8 located almost 200 feet west of
the Breen Property. PW-1 and PW-8 are the only deep aquifer wells located in areas of significant
shallow aquifer contamination.
PCE has been detected in two samples collected from private well PW-6, located about 1,000 feet south
of the Thurman Berwick Creek Area near the intersection of Labree Road and Rice Road, near the
southern margin of the shallow aquifer plume. In 1999, PCE was detected at an estimated 0.24 (ig/L.
However, the associated field duplicate was below the laboratory detection limit for PCE. In 2001, PCE
was detected at 2 (ig/L. Review of the laboratory report for this sample showed that the sample
identification was changed by the analytical laboratory from PW-4 to PW-6 (PW-4 is approximately 400
feet northeast of PW-6). A review of the E&E database showed the same analytical data reported for |
both PW-4 and PW-6, suggesting that the sample designations may have been confused. During J
subsequent sampling events, PCE was not detected in PW-6 groundwater samples.
There is limited data available from the deep aquifer in areas of significant shallow aquifer
contamination to conclude that the deep aquifer has not been impacted. Further, the data from the only
two wells screened within the deep aquifer in areas of significant PCE contamination were last collected
in 2003. No recent data has been collected from the deep aquifer to determine if PCE has migrated
below the aquitard.
4.4.6 Other Groundwater Analyses
Additional analyses have been conducted on a limited number of groundwater samples at the Site.
Three groundwater samples were analyzed for gasoline-range or diesel-range petroleum hydrocarbons
using NWTPH-Gx and NWTPH-Dx. TPH-G was analyzed in groundwater samples from borings GP-1
and GP-3 during the START investigation in 2000. GP-1 was located in the HRIA Southeastern Hot
Spot and GP-3 was located south of the United Rentals facility. A TPH-G concentration of 4,200 (ig/L
was detected at 16 feet bgs at GP-1 and non-detect at a MRL of 100 (ig/L at GP-3. TPH-D was analyzed
in a sample collected from PW-21, also during the START investigations in 2000. TPH-D was non-
detect at an MRL of 16 (ig/L. TPH analyses for the three groundwater samples are summarized in
Appendix A, Table A-4.
Samples collected from private wells PW-5 and PW-21 were analyzed for SVOCs using EPA Method
8270 during the Ecology investigations in 1999. In addition, pesticides analysis was conducted on a
sample collected from PW-5. No SVOCs or pesticides were detected above laboratory detection limits.
However, these wells are at the peripheral limits of the plume and are not relevant for determining
whether groundwater at the Site has been impacted by SVOCs or pesticides.
Conventional chemistry analyses were conducted on samples collected from a number of wells within
the HRIA during the EE/CA investigations (URS 2004). The results of these analyses are shown in
Table 2-11. Field parameters were collected during the July 2007 sampling event and are shown in
Table 2-12.

Section 4 • Nature and Extent of Contamination •
No analyses have been conducted for metals in groundwater at the Site. Select metals and inorganics
were analyzed in samples collected from private wells downgradient of the Site. The following metals
were detected in all samples: copper, iron, manganese, magnesium, potassium, sodium, and zinc.
4.5 Surface Water
Surface water samples were collected from Berwick Creek in 1998 by Ecology, in 2002 and 2003 by
Farallon, and from Dillenbaugh Creek in 2007 by Parametrix. Berwick Creek samples were collected
from a total of 10 stations, four established by Ecology in 1998 (SW-1 through SW-4), and six
established by Farallon in 2002 (SW-5 through SW-10). Samples were analyzed for VOCs; the results
are summarized in Table 2-4 and Appendix A, Table A-5.
4.5.1 HRIA
Four of the 10 surface water sampling stations are in the HRIA (SW-3, SW-5 through SW-7) and are
shown on Figure 2-3. The remaining stations are located downstream of the HRIA.
PCE concentrations in surface water in known areas of contamination in the HRIA ranged from non-
detect at an MRL of 0.2 (ig/L to 40 (ig/L (SW-5 unnamed ditch # 1) in November 2002. The detections
of PCE in surface water samples at the three locations have varied considerably, and no clear seasonal
trend has been identified. However, the highest concentrations of PCE at SW-7 and SW-5 were detected
in November 2002 (12 and 40 (ig/L, respectively), typically a high precipitation month.
Two additional stations are located upstream of the HRIA. SW-4, located in the upstream portion of
unnamed ditch #1 east of 1-5, was sampled once by Ecology in December 1998; PCE was not detected.
SW-6, located near the upstream limit of known contamination in Berwick Creek soils, was sampled
four times between luly 2002 and February 2003. PCE was detected at concentrations less than 1 (ig/L in
luly 2002, but was not detected above the laboratory detection limit (<0.2 j^ig/L) during later sampling
events.
No surface water sampling has been completed in Berwick Creek in the northern portion of the HRIA
between MW-R4 and MW-5/MW-33. High PCE concentrations have been detected in MW-R3
(Northwestern Hot Spot) and MW-33. It is unknown if contaminated groundwater near these wells
discharges to surface water.
4.5.2 Breen Property
One surface water sampling point is located in Berwick Creek adjacent to the Breen Property. SW-8 is
located just downstream of the western boundary of the HRIA. PCE was detected at low conentrations of
0.6 (ig/L and 0.67 (ig/L in two sampling events and was not detected in two other sampling events.
4.5.3 Thurman Berwick Creek Area
Surface water samples have been collected at three sampling points in Berwick Creek at the Thurman
Berwick Creek Area. SW-1 is located at the downstream end of the culvert passing under Labree Road.
SW-2 is located at the upstream end of the culvert passing under North Hamilton Road. SW-9 is located
just upstream of SW-1.
SW-1 and SW-2 were sampled by Ecology in 1998 and PCE concentrations ranged from 8.5 to 16 (ig/L,
similar to concentrations measured within the HRIA. Farallon sampled SW-9 in 2002 and 2003. PCE

Section 4 • Nature and Extent of Contamination •
concentrations ranged from non-detect at the laboratory reporting limit (<0.2) to 1 (.ig/L. The source of
PCE detected in surface water samples may be residual contamination in the creek bed sediment/soil.
4.5.4 Downgradient Areas West of Labree Road
SW-10 is located 1,300 feet downstream of Labree Road. PCE was detected in three of four sampling
events, but all concentrations were less than 1.0 (ig/L.
Two surface water samples (CS-1 and CS-2) were collected in July 2007 from Dillenbaugh Creek near
monitoring well MW-25 and downgradient of the confluence with Berwick Creek (Figure 2-4). CS-1
and CS-2 contained PCE at 1.7 and 3.6 (ig/L, respectively. These concentrations are higher than PCE
detected at SW-10 in Berwick Creek downgradient of Labree Road, indicating the PCE groundwater
plume may be discharging to Dillenbaugh Creek.
4.5.5 Other Surface Water Analyses
Six surface water samples collected by Farallon were analyzed for gasoline-range petroleum
hydrocarbons. Samples SW-5 through SW-10 were non-detect for TPH-G at an MRL of 100 (ig/L.
Petroleum hydrocarbon data for the six surface water samples are summarized in Appendix A,
Table A-6.
4.6 Creek Bed Sediment/Soil
This section describes the creek bed sediment/soil sampling conducted at the Site. Creek bed sampling
has historically only been conducted at the HRIA and the Breen Property. No sampling has been
conducted in the downgradient areas. Sampling results are presented in Table 2-5.
4.6.1 HRIA
During the HRIA EE/CA investigations, 39 shallow soil samples were collected from the bed and bank
soil along Berwick Creek and both unnamed ditches in the HRIA (URS 2004). The maximum PCE
concentration detected was 5,220 mg/kg in creek bed sample SB-409 (Figure 2-3). The lateral
distribution of PCE in the creek bed and bank appears to be discontinuous. PCE was not detected in
several of the creek bed and bank samples collected around SB-409, where the maximum concentration
of PCE was detected.
The Northwestern Hot Spot probably represents the maximum downstream extent of PCE DNAPL
movement along the bed of Berwick Creek from the HRIA release location. Creek bed samples
downstream from the Northwestern Hot Spot showed only low PCE concentrations (URS 2004).
The approximate extent of PCE contamination in the Berwick Creek bed at the HRIA is shown in the
additional isoconcentration maps prepared by URS (2004) included in Appendix D, Figures 2-3 and
2-4. The creek bed is located at an elevation of approximately 199 to 200 feet MSL.
No creek bed sediment/soil samples have been collected from Berwick Creek in the northern portion of
the HRIA, particularly in the segment between MW-R4 and MW-5/MW-33. It is unknown if there is a
separate potential creek source for the contamination detected in MW-33 or if other creek sources may
exist.

Section 4 • Nature and Extent of Contamination •
4.6.2 Breen Property
Creek channel samples CC-1 through CC-9 were collected by Farallon in September 2003 during Phase
II RI/FS sampling (Figure 2-3). The samples were collected from various locations along Berwick Creek
south of the Breen Property from the creek bed sediment at approximately 1 foot bgs. No PCE was
detected above laboratory detection limits in any of the samples; however, these samples may reflect
sediments deposited after PCE disposal.
4.6.3 Other Areas
No creek bed sediment/soil samples have been collected in the Thurman Berwick Creek Area or the
downgradient areas west of Labree Road. No source for the PCE in groundwater detected in the
Thurman Berwick Creek Area wells has been identified. A possible source for the contamination
includes a potential release to Berwick Creek south of the Breen Property. Conceivably, PCE DNAPL
flowed down Berwick Creek from the HRIA release and settled into this reach, but the lack of evidence
of DNAPL in the intervening creek bed deposits makes this scenario highly speculative. Deeper |
sediment/soil samples in Berwick Creek between the North Hamilton Road Bridge and Labree Road are |
needed.
4.7 Soil Gas
This section summarizes the results of soil gas investigations conducted at the HRIA and the Breen
Property. The results of the soil gas sampling are shown in Table 2-6 and locations are shown on
Figures 2-1 and 2-2.
4.7.1 HRIA
A soil gas survey was conducted within the HRIA north of Berwick Creek to assess a possible spill from
1-5. During the survey, soil gas samples were collected at 35 locations and analyzed for PCE using a
mobile laboratory (Figure 2-1). In general, PCE concentrations in the soil gas samples collected along I-
5 were very low (i.e., less than 1 ppm-v). Two samples, SG-208 and SG-209, contained PCE at 1.8 and
3.2 ppm-v, respectively. Other nearby samples, however, did not reveal a definable release location.
Overall, the soil gas survey results do not support the scenario of a release from 1-5.
4.7.2 Breen Property
Soil gas surveys were performed in two areas of the Breen property in November 2002 to qualitatively
assess the potential PCE source associated with elevated PCE concentrations detected in corresponding
groundwater samples. Soil gas samples were collected in the area of boring RS-1, in the central part of
the Breen Property, at locations SG1-1 through SG1-10, SG1-12 through SG1-14, and SG1-20. Samples
were also collected in the wash-down pad area near boring RS-7 at locations SG2-1 through SG2-6,
SG2-8, SG2-9, and SG2-15 (Figure 2-2). All samples were collected at 5 feet bgs and were analyzed for
PCE and TCE using EPA Method 802IB. Soil gas sample results were reported as non-detect at the
laboratory practical quantitation limit (PQL), indicating that these areas were not likely PCE source areas
(Farallon 2003).
4.7.3 Other Areas
No soil gas sampling has been conducted in the Thurman Berwick Creek Area or the downgradient areas
west of Labree Road.

4.8 Vapor Intrusion Sampling
In November 2007, EPA's ERT conducted air sampling in and around private residences and
commercial buildings across the Site. The resulting data were used to assess whether vapor caused from
volatilization of contaminants from the shallow aquifer was intruding into indoor and ambient air at the
Site. Soil vapor samples were also collected beneath concrete building slabs to assess if vapors were
concentrated beneath the structure that either were related to indoor air impacts, if present, or could
potentially affect indoor air if the concrete slab was breached.
Analytical results for the air samples are shown in Table 2-8. Discussion of air sampling results and
associated risks are discussed in the Baseline Risk Assessment Report included as Appendix G.
4.8.1 HRIA
Vapor intrusion sampling was conducted in and around the United Rentals Property within the HRIA.
Four samples were collected from the United Rentals facility area: two indoor air, one ambient air, and
one sub-slab soil vapor. Sampling locations are described in Table 2-7.
PCE was detected in all indoor air, ambient air, and sub-slab samples collected at the United Rentals
Property. The highest concentration of PCE (25 (.ig/nr1) was detected in the sub-slab sample.
4.8.2 Breen Property
Air sampling was conducted at several buildings on the Breen Property. Indoor air and sub-slab samples
were collected at Buildings B and C and the Chehalis Livestock Auction Building. In addition, ambient
air samples were collected from various locations near these buildings. A total of 12 samples were
collected, including five indoor air, four sub-slab soil vapor, and three ambient air (Tables 2-7 and 2-8).
PCE was detected in all indoor air, ambient air, and sub-slab samples collected at the Breen Property.
The highest concentrations of PCE were detected in the sub-slab samples collected from the main bay
(120 (.ig/nr1) and office (70 |_ig/m3) of Building B (Bulldog Trailer Company). Building B was the
location of subsurface drum removal activities in 1999.
The estimated risks from the volatilization of contaminants in groundwater to indoor air on the Breen
Property, based on the air sampling results, are below risk threshold levels. The evaluation of the limited
vapor intrusion data available suggests that this pathway is minor on the Breen Property. However,
vapor intrusion cannot be ruled out definitively, and several significant uncertainties lower confidence in
the risk evaluation.
All data collected are relatively old and may not reflect current conditions; thus, the evaluation
may not be relevant for 2011.
Air data were collected only once over a two day period. Air data may vary significantly over
time and by season, and it is not possible to determine how available data reflect air
concentrations over time. Possible exposure concentrations could be significantly under- or
over-estimated.
Outdoor air data suggest that this medium may be a major source to indoor air. A large
contribution from outdoor air could make a smaller contribution from the subsurface. It was
difficult to determine how shallow groundwater data reflect VOC concentrations at the top of the
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11

water table. Such data best characterize the source of VOCs in soil gas, and would be best for
estimating ratios between indoor air and groundwater. Ratios could be either under- or over-
estimated.
Overall, the evaluation of vapor intrusion is limited, and confidence in conclusions of the assessment is
low. Additional data would be necessary to provide a more useful evaluation of this pathway.
4.8.3 Thurman Berwick Creek Area
Five samples were collected at and adjacent to the Thurman residence, including two indoor air, two
crawlspace air, and one ambient air (Tables 2-7 and 2-8). The highest concentration of PCE (0.23
(ig/m3) was detected in an ambient air sample collected adjacent to Berwick Creek (Ambient 002/Unit
004). A potential source for groundwater contamination identified at the Thurman Property may be
located in Berwick Creek upgradient of the property and may be impacting ambient air.
4.8.4 Downgradient Areas West of Labree Road |
Vapor intrusion sampling was conducted in five residences located on Labree Road and on Rice Road,
w est of Labree Road. In addition, one commercial location (Giske Imaging) located on Rice Road was
sampled. Thirteen samples were collected, including five indoor air, five crawlspace air, two ambient air, f
and one sub-slab soil vapor (Tables 2-7 and 2-8). The highest concentration of PCE was detected in the f
crawlspace sample (0.81 (ig/m3) collected from the residence at 2364 Rice Road.

Section 5
Contaminant Fate and Transport
This section describes the fate and transport of PCE in groundwater across the Site, including
a discussion on release mechanisms from primary and secondary source areas, potential
routes of contaminant migration, contaminant persistence and degradation, and concentration
trends analysis. The results and limitations of groundwater modeling conducted for the Site
are provided.
5.1 Source Areas, Release Mechanisms and Potential
Routes of Migration
The following sections describe the primary and secondary source areas and release
mechanisms, and the potential routes of contaminant migration to the various media across
the Site. A graphical depiction of the CSM is included as Figure 5-1.
5.1.1 HRIA
As described previously, the apparent primary source of contamination at the HRIA is a spill
or dumping of liquid PCE into Berwick Creek in the vicinity of monitoring well MW-602
(Southeastern Hot Spot, Figure 4-1). Berwick Creek within the HRIA is an intermittent and
relatively low-velocity stream. The two rounds of stream flow data collected to date have
shown a maximum flow rate of only 6 cubic feet per minute in the reach of the stream that
passes through the source area. The amount and rate at which PCE dissolves and is carried
downstream will vary with the stream flow rate at the time of the spill. In times of creek
flow, a release of sufficient quantity would have resulted in some of the PCE sinking through
the creek water column and settling on the creek sediment as DNAPL since the density of
PCE is greater than water. When there is no flow, the dumped PCE would pool on the creek
bed surface and seep into the ground until there is sufficient stream flow to dissolve some of
the PCE and carry it downstream.
Once pooled on top of the creek bed sediment, the PCE leached into the sediment and
continued to migrate downward until it reached the shallow groundwater aquifer. PCE tends
to be highly mobile in the subsurface environment with transport rate and extent vertically
and laterally dependent on site physical features (e.g., stratigraphy, hydraulic conductivity,
and porosity) and hydraulics (i.e., groundwater flow direction and magnitude). In the absence
of transport via hydraulic advection/dispersion, transport may still occur through an aquitard
by diffusion, i.e., migration in response to a concentration gradient in the absence of
groundwater flow. The DNAPL resting on the floor of the creek bed acts as a continuing
source of PCE leaching into the subsurface soils.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11

-------
Section 5 • Contaminant and Transport •
Upon reaching the aquifer, some of the PCE dissolved in the groundwater and began moving laterally
with the shallow aquifer. The DNAPL in the aquifer would continue to gradually dissolve, providing a
long-term source of PCE contamination in groundwater. It would also diffuse into the lower-
permeability lenses within the shallow aquifer and subsequent back-diffusion provides a weaker, but
longer-term source of PCE to groundwater. Concentrations in the groundwater are high enough to
suspect that the release to the creek was of sufficient quantity to have also resulted in DNAPL
conditions within the shallow groundwater aquifer (based on groundwater detections exceeding 10% of
the solubility limit or 20,000 (ig/L PCE). The DNAPL portion of the plume would appear to be
centered on the area of MW-602, based on the high concentration of 2,720,000 jj.g//L observed in
November 2003.
Dense and very dense soils and zones of higher silt content appear to have impeded vertical migration
of PCE DNAPL beneath the release zone. As a consequence, the PCE DNAPL apparently spread
laterally through preferential pathways, with concentrations indicative of DNAPL found upgradient of
the creek as far as location AB-650, approximately 80 feet southeast of MW-602. Vertical movement
of PCE DNAPL may have been impeded by zones such as the very dense, fine-grained sand found at 30 |
feet bgs beneath the creek in several borings (Plate 4 in Appendix D). However, PCE as DNAPL did !
penetrate this zone, but is generally not found below about 35 feet bgs. The exception is MW-9, about )
40 feet northwest of MW-602, where PCE concentrations in soil samples imply DNAPL presence as
deep as 43 feet. A soil concentration greater than 38 mg/kg indicates DNAPL as calculated by URS in
the EE/CA Report (URS 2004).
PCE concentrations in groundwater indicative of DNAPL are generally not found below 35 feet bgs
(URS 2004). Thus, DNAPL does not appear to have reached the silt and clay aquitard at the bottom of
the shallow aquifer (Plate 4 in Appendix D).
The Northwestern Hot Spot within the HRIA appears to be the result of PCE DNAPL movement in
Berwick Creek downstream of the primary release location, in relatively small quantities compared to
the southeastern release location. The Northwestern Hot Spot probably represents the maximum
downstream extent of PCE DNAPL movement along the bed of Berwick Creek from the HRIA release
location. Samples from the soil beneath the creek found only intermittent evidence of this downstream
movement, indicating that the volume of PCE DNAPL was nearly exhausted. Sufficient DNAPL was
present, however, to result in significant sorbed and dissolved concentrations of PCE in the area of the
Northwestern Hot Spot (URS 2004).
Significant levels of contamination from the HRIA are limited to the lower zone of the shallow aquifer
downgradient of United Rentals. Over much of the area between United Rentals, the Breen Property
wash-down pad, and the Thurman Berwick Creek Area, the upper zone of the shallow aquifer is non-
detect for PCE over a north-south section stretching from RS-2 to RS-24. In this vertical "bottleneck",
contamination is mostly restricted to the lower zone. Some shallow contamination (maximum 400
(ig/L) is found in the RS-1 area on the Breen Property north of RS-46. It is unknown if the source is
local (on the Breen Property) or whether it is from the HRIA, perhaps the Northwestern Hot Spot.
There could be multiple reasons that account for this pattern of contaminant migration. Lateral and
vertical hydraulic gradients may be different in the upper and lower zones of the shallow aquifer. In
addition, seasonal changes in gradient should also be evaluated. Because PCE is denser than water and
much of the dissolved PCE may have originated from DNAPL in the aquifer, the contaminant plume

will tend to move downward. Additional characterization is needed to determine the cause of the rapid
decline in concentrations, particularly in the upper zone downgradient of the HRIA.
Based on groundwater flow calculations, the shallow aquifer plume emanating from the HRIA may
have migrated about 1,500 to 2,000 feet, or to roughly 500 feet west of Labree Road, assuming that the
HRIA disposal did not occur much before 1990 (URS 2004 page 2-18). However, other data suggest an
older HRIA source. Private drinking water well PW-21, located along Rice Road, was non-detect (<1
(ig/L) in 1999 and had a detection of 4.6 (ig/L in 2001. The PCE concentration has subsequently
fluctuated slightly above and below 5 (ig/L. Since this well is on the southwestern edge of the plume, it
may record the arrival of contamination from the HRIA that had previously been pulled south by
former production wells located south of the HRIA and the Thurman Berwick Creek area, or it may be
associated with another potential source located upgradient of PW-21. Additional evaluation is
necessary to assess whether the PCE detected in PW-21 is from the HRIA. If it is, then the assumption
that HRIA disposal occurred shortly before 1990 is not supported. It would instead suggest that disposal
occurred sometime in the 1970s. If this is the case, then the HRIA contribution to contamination in the
lower portion of the plume downgradient of Labree Road may extend considerably further
downgradient than estimated above. However, the proportion attributable to the HRIA would be limited
to the transport from the "bottleneck" area — less than half of the PCE mass found in the lower zone of
the aquifer (below 25 feet) and none of the PCE in the upper zone. As noted earlier, a mass
flux/discharge evaluation would need to be conducted to verify the contaminant contribution from the
HRIA, through the "bottleneck," to downgradient areas.
5.1.2 Breen Property
The groundwater contamination at the Breen Property appears to be related to multiple releases related
to site operations between the early 1960s and early 1990s, combined with some PCE from the HRIA
source areas, particularly in the deep zone of the shallow aquifer along and north of North Hamilton
Road.
Although containers of source product and contaminated soil were removed below Building B in 1999,
no reduction in groundwater PCE concentrations has been observed in nearby monitoring wells,
compared to groundwater samples collected directly from borings at the time of the removal. This could
suggest a continuing, as yet undiscovered, source of contamination to groundwater in the vicinity of
Building B; however, neither the borings nor the monitoring wells may have been placed optimally to
measure changes in PCE levels.
Other potential sources appear to exist on the Breen Property; the wash-down pad in particular is an
area with significant (greater than 1,000 (ig/L) concentrations of PCE in the shallow zone, indicating a
source of contamination. However, further investigation is necessary to determine the exact location
and nature of potential sources.
Similar to the HRIA, releases of PCE or PCE-contaminated water to the soil or to Berwick Creek from
the Breen Property would have migrated vertically through the soil and the lower-permeability silt cap
to the shallow groundwater aquifer. The depth of groundwater contamination at the Breen Property and
at the Thurman Berwick Creek Area, suggests that PCE is, or possibly has been, present as DNAPL at
some sources. However, to date, no areas with concentrations high enough to suggest the presence of
DNAPL have been identified. Remaining continuing sources to groundwater likely include dispersed
residual DNAPL, PCE adsorbed to soils, and PCE diffused into lower-permeability soil layers. PCE in

-------
Section 5 • Contaminant and Transport •
groundwater at the Breen Property appears to be migrating in the shallow aquifer in the dissolved
phase. However, the Breen Property has not been fully characterized to determine if potential DNAPL
sources are present on the property. This information is necessary to fully assess the behavior of PCE at
the Breen Property.
5.1.3 Thurman Berwick Creek Area
As with the Breen Property, PCE in groundwater appears to be migrating in the shallow aquifer in the
dissolved phase in the Thurman Berwick Area. Upper zone groundwater PCE concentrations may be
related to an additional PCE release to Berwick Creek south of the Breen Property or migration of PCE
contamination from another PCE source within the Site between Berwick Creek and monitoring wells
MW-22/MW-23 and sampling locations RS-19/RS-19A. PCE in the lower zone likely includes a
contribution (less than 1,000 (ig/L) that has migrated from the HRIA. Additional characterization is
necessary to determine if a potential source (possibly a DNAPL source) is present immediately
upgradient of the Thurman Property, and, if it is from disposal into Berwick Creek, how far
downstream it extends.
5.1.4 Downgradient Areas West of Labree Road
Data are limited immediately west of Labree Road, but farther downgradient, the core of the plume
(greater than 500 (ig/L) is apparently relatively narrow and long and does not appear to attenuate much
over a 3,000-foot distance based on analytical data. This pattern suggests that much of the
downgradient plume is from an older, discrete PCE point source that may have been stable for an
extended period. Alternatively, additional sources may be present downgradient, perhaps in Berwick
Creek near where it crosses the plume centerline.
5.1.5 Secondary Release Mechanisms
When a released contaminant is retained in an environmental medium such as soil or sediment, the
medium functions as a secondary source for further release of the contaminants. The following
paragraphs discuss the release mechanisms from the secondary media sources.
Sediment Migration in Berwick Creek
Contaminated sediment in Berwick Creek has the potential to migrate downstream under the influence
of the stream current. The timing and magnitude of migration depends upon surface water flow
conditions that change seasonally due to precipitation. Area-wide flood events in recent years appear to
have scoured certain portions of Berwick Creek, including the channel within the HRIA, down to the
silt cap, so that the original contaminated sediment is no longer present.
Leaching from Contaminated Berwick Creek Sediment to Surface Water
Contaminated sediment that migrates downstream is in constant contact with surface water, creating the
potential for leaching of PCE to surface water at points downstream from the original release to
Berwick Creek.
Volatilization from Surface Water to Air
PCE dissolved in Berwick Creek water would be subject to volatilization from the water into the
ambient air. The magnitude of this volatilization would depend upon the concentrations in the stream,
turbulence, and ambient weather conditions.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
49
-------
Section 5 • Contaminant and Transport •
Volatilization from Soil to Air
PCE in soil may volatilize to ambient air, depending upon the concentration, distance between the
contamination and the surface of the soil, and weather conditions. This may be a particular concern for
excavations into contaminated soils.
Leaching to Groundwater
Precipitation infiltrating through soil contaminated with PCE may result in migration of PCE to
groundwater. Groundwater occurs at relatively shallow depths in the HRIA, and the rate and magnitude
of migration depends on the nature of the soils above the water table and the amount of seasonal
precipitation.
Volatilization from Groundwater through Soil to Air
Volatilization of PCE in groundwater has the potential to migrate to the soil and ultimately to ambient
air and, potentially, indoor air. Such releases would be dependent upon the concentration in
groundwater, the depth of groundwater below the land surface, presence and thickness, or absence of a j
low-permeability layer above the groundwater table, and weather conditions. In addition, although |
impacted private water wells are purported to no longer be in use, particularly as a drinking water J
source, continued use of these wells for secondary uses such as irrigation, showering, toilets, or wash j
water, may result in exposures through volatilization and subsequent inhalation.
Downgradient Discharge from Groundwater to Surface Water
Hydrogeologic data collected in the HRIA indicate that the reach of Berwick Creek that flows through
the HRIA is underlain by fine-grained silt and clay, which separates the stream from groundwater. If
this layer is absent, fractured, or breached by Berwick Creek, Dillenbaugh Creek, or the Newaukum
River downstream of the HRIA, PCE-contaminated groundwater can discharge to surface water.
Sampling results indicate that contaminated groundwater is likely discharging to the creeks.
Further discussion of the CSM as it relates to potential risk to human health and the environment is
discussed in Section 6, Baseline Risk Assessment.
5.2 Contaminant Persistence
The process of reducing mass, toxicity, mobility, volume and/or concentrations of contaminants from
soil or groundwater without human intervention is referred to as natural attenuation (EPA 1997a).
These in situ processes include dispersion, dilution, sorption, volatilization, and chemical or biological
stabilization, transformation, or destruction of contaminants (EPA 1997a). The methods, degree of
transformation that occurs, and timing of natural attenuation depend upon a multitude of factors,
including the contaminant type, magnitude of the release, and site-specific subsurface conditions.
Many of the physical processes of natural attenuation (i.e., dispersion, volatilization, dilution) rely more
on mass transfer, rather than destruction. These processes are the secondary release mechanisms that
were discussed in Section 5.1.5. Under appropriate conditions PCE biodegrades, whether partially or
fully. The biodegradation processes of PCE and an evaluation of biodegradation of PCE at the Site is
described in the following sections.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
50
-------
Section 5 • Contaminant and Transport •
5.2.1 Biodegradation Processes of PCE
The primary degradation pathway for PCE is microbially-mediated reductive dehalogenation, whereby
its chlorine atoms are successively stripped off to form less chlorinated compounds. PCE is
successively degraded to TCE, DCE, vinyl chloride, ethene, and finally carbon dioxide as shown on
Figure 5-2. DCE occurs as three isomers: 1,1-DCE, cis-l,2-DCE, and trans-l,2-DCE. The cis-1,2-
DCE isomer is by far the most prevalent product of the degradation of PCE and TCE. The
biodegradation pathways for PCE's daughter products can vary and include electron donor reactions
(anaerobic oxidation and aerobic oxidation), electron acceptor reactions (reductive dehalogenation), and
aerobic cometabolism (oxidation) as shown on Figure 5-2.
5.2.2 Assessment of In Situ Biodegradation
The assessment of in situ biodegradation of PCE is typically demonstrated through assessment of
multiple lines of evidence. The most obvious evidence of PCE biodegradation is the presence of its
daughter products. The daughter products of PCE were not always analyzed in Site samples, but when |
they were analyzed they were rarely detected, and when they were detected the concentrations were |
relatively low. One exception is an area west of Building B on the Breen property, which is discussed j
later in this section. !
To evaluate whether conditions are conducive for biodegradation and to further demonstrate that
biodegradation is occurring requires analysis of a variety of additional parameters in groundwater, such
as: dissolved oxygen (DO), nitrate, ferrous iron, sulfate, sulfide, methane, ethene, oxidation reduction
potential (ORP), total organic carbon, and chloride. In 2004, a suite of conventional chemistry analyses
was completed on groundwater samples collected from wells MW-600 through MW-608 within the
HRIA (Table 2-11). MW-600 through MW-604 are located within the Southeastern Hot Spot. MW-
605 is located just downgradient of the hot spot. MW-606 through MW-608 are located down or cross
gradient of the hot spot. Table 2-12 presents field measured parameters of DO, ORP, temperature, pH,
conductivity, and turbidity for 10 Site-wide monitoring wells in July 2007.
PCE Daughter Products: One area on the Breen Property shows significant concentrations of the PCE
daughter products. Downgradient of Building B, groundwater from the upper zone of the shallow
aquifer at three locations (MW-17 (19.7-23 feet), B-14 (20 feet), and SP-8 (15 feet)), and one location
on the upgradient side (SP-6 (15 feet)), contained virtually no PCE or TCE, but instead contained
significant concentrations of cis-l,2-DCE and vinyl chloride. More specifically, in B-14, PCE and TCE
were non-detect at the laboratory reporting limit (<1.0 (ig/L). while cis-l,2-DCE and vinyl chloride
concentrations were 610 (ig/L and 68 (ig/L, respectively. Concentrations of PCE and TCE in MW-17
were less than 4 (ig/L, but cis-l,2-DCE concentrations ranged between 230 (ig/L and 510 (ig/L and
vinyl chloride concentrations ranged between 230 (ig/L and 480 (ig/L. In SP-7, PCE and TCE were
non-detect and cis-l,2-DCE and vinyl chloride were 101 (ig/L and 449 (ig/L, respectively. In SP-8,
PCE and TCE were non-detect and cis-l,2-DCE and vinyl chloride were 700 (ig/L and 857 (ig/L,
respectively.
In addition, it is noted that at MW-R3, located in the Northwestern Hot Spot area, cis-l,2-DCE was low
to non-detect from 1999 until 2002. In August 2002, cis-1,2- DCE concentrations began to increase,
while PCE concentrations generally declined. The changes coincided with notation of sample
collection depths from the upper zone of the shallow aquifer. Previously, the depth interval was not
noted, so it is likely that the earlier samples were collected from the lower zone and that no change has

occurred in the groundwater chemistry related to the degradation of PCE. These results indicate that
PCE in the upper zone is being at least partially degraded (vinyl chloride concentrations were all low to
non-detect).
Dissolved Oxygen: Reductive dechlorination is not expected to occur if DO is above about 0.5 mg/L.
DO concentrations in the HRIA monitoring wells ranged between 0.69 and 4.06 mg/L. DO
concentrations in the Site-wide wells ranged between 3.21 and 5.87 mg/L. The only sample with DO
less than 1 mg/L was collected from MW-600. DO data should be used in a qualitative manner since
accurate DO measurements are difficult to obtain, especially when measuring below 1.0 mg/L. DO
concentrations at the Site are generally too high to be conducive for reductive dechlorination processes.
Oxidation Reduction Potential: ORP is a measure of the electrochemical potential associated with the
transfer of electrons from one substance to another. ORP is a qualitative measurement because
measurements assume the system is at equilibrium and several factors affect the accuracy of the
measurements. ORP values of -100 millivolts (mV) or less are favorable for reductive dechlorination.
ORP measurements in the HRIA wells ranged between 140 and -63 mV. In the Site-wide wells, ORP
ranged between 351 and 413 mV. Values between about 50 mV and -100 mV are not within the
optimal range for reductive dechlorination, but they are low enough for it to occur. Only five samples
were below 50 mV; all were HRIA wells.
Ferrous Iron: When ferric iron (Felll) is used as an electron acceptor during anaerobic biodegradation
of organic carbon, it is reduced to ferrous iron (Fell) (Weidemeier 1998). Thus, the presence of ferrous
iron in groundwater indicates reducing conditions. Ferrous iron was not detected in any of the
groundwater samples analyzed.
Sulfate: The role of sulfur in the bioremediation of chlorinated solvents is complex and multifaceted,
as it can be both problematic and advantageous. Sulfate must be reduced in order to reach
methanogenic conditions where reductive dechlorination proceeds most readily, but there is ample
evidence in the literature for dechlorination of a wide variety of chlorinated solvents under sulfate
reducing conditions (ARCADIS G&M, Inc. 2002). Sulfur and sulfur-containing compounds can aid in
the biological degradation of chlorinated solvents through a variety of mechanisms, including
stimulation of dehalogenation by sulfate reducers, abiotic degradation of chlorinated solvents by iron
sulfide, and involvement as reductants and/or intermediates in the degradation mechanisms of
chlorinated solvents (ARCADIS G&M, Inc. 2002). However, elevated levels of sulfide [as a result of
sulfate reduction] may be toxic to dechlorinating microorganisms (ARCADIS G&M, Inc. 2002).
Weidemeier (1998) states that "Concentrations of sulfate greater than about 20 mg/L may cause
competitive exclusion of dechlorination." Sulfate concentrations in the HRIA groundwater samples
ranged between 1 and 34 mg/L. Sulfide was not detected in any of the groundwater samples (<2 mg/L).
Nitrate: Nitrate concentrations ranged between 0.5 and 1.7 mg/L. Concentrations greater than 1 mg/L
may compete with the reductive dechlorination pathway. Nitrate concentrations at the Site do not
appear to be high enough to compete with the reductive declorination pathway.
Alkalinity: In general, a positive correlation between zones of microbial activity and increased
alkalinity is expected because the carbon dioxide produced by biological activity increases alkalinity in
typical groundwater pH ranges. Alkalinity ranged between 72 and 150 mg/L. Except for MW-602,
alkalinity concentrations in and just downgradient of the Southeastern Hot Spot area were over 100
mg/L. Alkalinity concentrations in monitoring wells downgradient of the hot spot were slightly lower.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
52
-------
Section 5 • Contaminant and Transport •
While the difference is not really significant, the increased alkalinity concentrations may indicate slight
increased biological activity in the source area.
Chloride. Chloride concentrations greater than two times background can be indicative of
biodegradation. Chloride concentrations ranged between 1 and 1.3 mg/L in the four wells
downgradient of the Southeastern Hot Spot, while chloride concentrations in wells located within the
Southeastern Hot Spot were significantly higher, ranging between 5.4 and 9 mg/L.
5.2.2.1 Conclusions
Available analytical data suggest that biodegradation of PCE throughout the Site is very minimal with
the exception of a small area in the shallow zone of the upper aquifer west (downgradient) of Building
B on the Breen property. Minimal groundwater data are available to evaluate why PCE degradation is
occurring downgradient of Building B as only ORP and DO data were collected for MW-17. DO
concentrations ranged between 0.39 to 1.0 mg/L, lower than nearly all other locations where DO data
are available. ORP ranged from 65 to 170 mV which do not appear favorable for reductive
dechlorination.
Field monitoring data indicates that conditions throughout the Site are not generally conducive for
biodegradation of PCE. DO and total organic carbon concentrations are likely the most limiting factors
for biodegradation processes. Additional studies would need to be completed to determine the
dynamics in the one area of the Breen property where conditions are conducive for biodegradation of
PCE.
5.3 Contaminant Fate: Concentration Trend Analysis
An evaluation of concentration trends in groundwater and surface water data was completed at various
well locations and surface water sampling points. Wells and surface water sampling points were
selected based on the location and number of data points available. Sampling locations with fewer than
three data points were not evaluated. Statistical analysis was not conducted, so the evaluation was semi-
qualitative in nature. Moreover, several wells have long screens through aquifer zones of varying
concentration, so apparent trends may reflect variability in the depth at which the sampling pump was
set. Concentration trend plots are presented in Appendix F.
5.3.1 Monitoring Wells
5.3.1.1 HRIA
In general, most monitoring wells within and immediately downgradient of the HRIA showed an
increase in PCE concentrations in groundwater between 1999 and 2003. MW-R1, MW-R2, MW-R4,
MW-R5, MW-R7, and MW-R10 all show generally increasing PCE concentrations. These wells are all
located downgradient of the release area, and all, except MW-R10, are screened in the upper zone of
the shallow aquifer. MW-R1, MW-R2, and MW-R5 are located closest to the HRIA and show the
highest increase in concentration.
Decreasing PCE concentrations were observed in upper zone wells MW-R6 and MW-R9 (screened
across both zones) between 1999/2000 and 2002, but they showed an increase in 2003. Both of these
wells are located downgradient of the HRIA. PCE concentrations in upper zone well MW-R3, located
northwest of the release area, fluctuate with no apparent increasing or decreasing trend.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
53
-------
Section 5 • Contaminant and Transport •
Decreasing concentrations are apparent in lower zone well MW-9, located adjacent to the HRIA, and at
MW-R11 (screened across both zones), located southeast of the United Rental building. Between
August 2000 and November 2003, MW-9 has shown a decrease of almost 35,000 (ig/L of PCE.
5.3.1.2 Breen Property
PCE concentrations in monitoring wells on the Breen Property are fluctuating, relatively constant, or
slightly increased. PCE concentrations in lower zone monitoring well MW-6 fluctuate, but the overall
change in concentration is relatively small. PCE concentrations in lower zone well MW-8, located
downgradient of the wash-down pad, fluctuated between approximately 1,400 j^ig/L and 2,100 (ig/L
between 1997 and 2003, but no overall increasing or decreasing trend is apparent.
Slightly increasing trends in PCE concentrations are indicated in lower zone wells MW-2 and MW-21
and upper zone well MW-20. However, there is insufficient data for MW-20 and MW-21 to evaluate a
trend. MW-20 and MW-21 are a well cluster located downgradient of the wash-down pad near the west
property boundary (Figure 2-2). MW-2 is located in an area between Building C and the Torpedo
Tube.
PCE concentrations in lower zone well MW-19, located downgradient of the Torpedo Tube area, were
relatively constant at about 1,400 (ig/L between 2002 and 2007. The most significant concentration
difference occurred in two samples taken less than two weeks apart in August 2002 (1,400 (ig/L versus
1,600 (ig/L). which likely indicates a variation between samples (i.e., sampling, analytical variation),
rather than over time.
Lower zone well MW-18, located west and downgradient of Building B, showed a steady increase in
PCE concentrations from 54 (ig/L to 89 ug/L between 2002 and 2003.
5.3.1.3 Thurman Berwick Creek Area
MW-23 and MW-24 are lower zone wells located upgradient of the Thurman Berwick Creek area,
south of the Breen Property, and between United Rentals and the Thurman Berwick Creek Area. PCE
data for the three sampling events in 2002 and the first part of 2003 were relatively consistent, after
which PCE concentrations increased. MW-4, located south of the Thurman Berwick Creek Area and
generally downgradient of MW-24, showed an overall increasing trend in PCE concentrations, but quite
a bit of variation between individual sampling events. The concentration of PCE in MW-4 showed a
sharp increase in 2001 (900 (ig/L). followed by a steady decrease (down to 460 (ig/L in February 2003),
then an increase between November 2003 and July 2007 (up to 920 (ig/L). similar to MW-23 and MW-
24. The recent increases may be related to the migration of the southern and northern lower zone lobes
of the PCE plume from the HRIA.
Within the Thurman Berwick Creek Area proper there are only two monitoring wells: lower zone well
MW-31 and upper zone well MW-32, both located on either side of Berwick Creek just south ofNorth
Hamilton Road. MW-31 was sampled only twice within a period of few months in 2003, so no trend
can be established. Between 2003 and 2007, the well was buried under a mound of dirt and could not be
sampled. MW-32, sampled only three times between 2003 and 2007, showed an increase in PCE
between 2003 and July 2007 (from approximately 2,000 (ig/L to 2,700 j^ig/L). Since the upper zone well
MW-22, located upgradient of MW-32, showed a maximum concentration of 38 (ig/L of PCE
(February 23, 2003), the increase in MW-32 does not appear to be attributed to an advance of the HRIA
plume.

5.3.1.4 Downgradient Areas West of Labree Road
There is only one monitoring well located within the PCE plume downgradient of Labree Road: lower
zone monitoring well MW-25. This well is located 2,400 feet west of Labree Road. PCE concentrations
at MW-25 appeared to be relatively stable between 2002 and 2007.
5.3.2 Private Wells
Groundwater data collected from private wells between 1993 and 2007 reflect different trends, but
many wells outside source areas indicate recent overall decreasing concentrations. The downward
concentration trend in a number of the private wells may be associated with decreased well pumping
following installation of the new City of Chehalis water supply line in 2002 and shut down of dairy
wells. PW-2, located north of the Smith Tractor building (Figure 4-1), was replaced by a new well
completed in the deeper aquifer. PW-4, located at a dairy farm south of the Breen Property along
Labree Road, and PW-5, located to the southeast of PW-4, were also shut down. Based on
conversations with Michael Meyers of URS (URS 2005), PW-4 was used as a production well for the |
|
dairy farm and may have been in part responsible for pulling the PCE groundwater plume to the south. |
Private wells PW-4, PW-5, and PW-7 show substantial variation between sampling events until about j
2002. In late 1998, a sharp decline in PCE was observed in all three wells, then in 2002 PCE showed a j
more consistent decline. PCE concentrations in PW-2 were fairly consistent from 1993 until 1998,
when the level declined by about 25 percent.
PW-3, located on the United Rentals Property within the HRIA (Figure 2-1), showed generally
increasing PCE concentrations between 1993 and January 2001, with an abrupt increase between
August 2000 and January 2001 (from 350 (ig/L to 930 j^ig/L). PCE concentrations declined to 560 (ig/L
in November 2002.
PW-9 showed substantial fluctuations in PCE concentrations between 1994 and 2003 from 460 (ig/L to
3,740 (ig/L. This well is located in the Thurman Berwick Creek Area within an area of elevated PCE
concentrations in groundwater.
PW-21 is located along the southern edge of the plume about 1,800 feet west of Labree Road. Since
PCE contamination was first observed at this well in 2001, it has shown a steady trend close to or
slightly above 5 (ig/L. Because PW-21 is located on the southern edge of the plume, it may record the
arrival of contamination from the HRIA that was pulled south by former production wells located south
of the HRIA and the Thurman Berwick Creek Area. Alternately, it may be associated with another
potential source upgradient of PW-21.
5.3.3 Surface Water Monitoring Stations
PCE concentrations in samples collected from Berwick Creek monitoring stations (SW-5 through SW-
10) were generally low with occasional peaks, but there is insufficient data to indicate whether PCE
concentrations are fluctuating. The largest peaks occur mostly during the winter months. This type of
trend is anticipated because of seasonal changes in flow rate in the creek and the potential for releases
of PCE from creek bed sediment during periods of high flow and creek bed scouring.
5.3.4 Trend Conclusions
The following general PCE concentration trends were observed during data analysis.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11

-------
Section 5 • Contaminant and Transport •
In general, monitoring wells located downgradient of the HRIA continue to show an increase in
concentration of PCE overtime (e.g., MW-R1, MW-R2, MW-R4, MW-R5, MW-R7 and MW-R10).
Wells located at the upgradient edge of the HRIA release area (i.e., MW-9) or cross-gradient (i.e., MW-
R11) have shown decreasing concentrations with time. However, the PCE concentration decrease
observed at MW-R11 may be related to shutdown of nearby shallow private wells and not related to a
declining PCE source at the HRIA.
The concentrations in most of the lower zone wells upgradient of the Thurman Berwick Creek Area
showed an increase during the last few sampling rounds, most likely in response to increasing
contributions from the advancing PCE plume from the HRIA.
Overall, PCE concentrations on the Breen Property fluctuate with little apparent declining or increasing
trends.
A downward concentration trend has occurred in a number of the private wells located outside of
source areas that may be associated with decreased well pumping following installation of the new City
of Chehalis water supply line in 2002 and shut down of dairy wells. |
5.4 Modeling of Contaminant Fate and Transport
Several modeling efforts have been completed for the Site to assess contaminant fate and transport in
groundwater. These efforts are summarized in the following sections.
5.4.1 History of Modeling Efforts
Four modeling efforts have been performed at the Site, three for the HRIA and its plume, and one for
the Breen Property source and plume. None of the models adequately reproduces the observed plume(s)
or explains apparent plume behavior. As such, none of the models based on existing Site data are
capable of making useful predictions regarding either current or eventual plume length, contaminant
distribution within the plume(s), or plume longevity. However, the numerical modeling results provide
some insights into the hydrologic system at the Site, including likely interactions between the plume
and the two creeks running through the Site.
5.4.1.1 Analytical Modeling
During completion of the HRIA EE/CA, the future fate and transport of PCE at the HRIA was
evaluated using EPA's screening tool Biochlor, Version 2.2. This model was used to estimate the
maximum eventual extent of the PCE plume downgradient of the HRIA in the absence of source
control and to estimate the general effects of implementing source control.
The HRIA Biochlor analysis showed the following results:
One or more sources located downgradient of the HRIA are contributing to the Site-wide plume. The
HRIA alone cannot account for the downgradient distribution of PCE.
With biodegradation assumed, the eventual maximum plume length resulting from a constant source at
Berwick Creek is unlikely to exceed 3 miles; without biodegradation, the maximum plume length
cannot be estimated and concentrations beyond 3 miles will eventually exceed 30 |a,g/L. However,
sampling and analysis conducted during the EE/CA investigations, and as discussed above, show that
biodegradation is likely not a major attenuation process at the Site.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
56
-------
Section 5 • Contaminant and Transport •
With the constant source (DNAPL) removed and dissolved concentrations reduced by 85 percent in the
HRIA, the eventual maximum plume length attributable to the source is unlikely to exceed 2 miles even
with no biodegradation.
With dissolved concentrations at the HRIA reduced by 85 percent, the plume is predicted to eventually
attenuate to an average concentration below MCLs, although attenuation in the release areas and within
the groundwater plume would require hundreds of years because of back diffusion from finer-grained
layers and lenses.
Modeling using Biochlor was completed by Farallon (2004, unpublished) during completion of Phase II
RI/FS activities. The Biochlor analysis was conducted for sources at the HRIA, the Thurman Berwick
Creek Area, and the Breen Property. It concluded that PCE concentrations would not migrate greater
than 3,500 feet from the Breen Property, with or without biodegradation occurring. Thus, it would most
likely be reduced through natural attenuation processes to concentrations below MCLs prior to reaching
additional downgradient drinking water sources.
|
The same modeling results made a similar prediction for the PCE concentration at PW-9 at the |
Thurman Berwick Creek Area under that same scenario. j
5.4.1.2 Three-Dimensional Numerical Modeling
Three-dimensional groundwater modeling was completed using MODFLOW-96 and MT3DMS (CDM
2007). The modeling was completed to assess the existing Site-wide groundwater contaminant plume
and the potential future impacts related to plume migration. The groundwater modeling task had the
following objectives:
Develop a steady-state numerical model of the hydrogeologic system at the Site.
Build a solute transport model into the numerical model to describe the fate and transport of
dissolved PCE within the aquifer.
Assess the behavior of the PCE in groundwater assuming a "no action" remedial alternative and
assuming source removal or hydraulic containment at the HRIA.
The results of the groundwater modeling effort showed the following:
Appreciable amounts of hydrogeologic and transport data are available from locations near the
Site properties. However, at distances from the properties, especially west of Labree Road
where approximately 75% of the PCE plume exists (as estimated from the modeled area of the
plume), available data are limited.
No, or negligible biodegradation is occurring since minimal concentrations of PCE daughter
products are detected in wells with exceedingly high concentrations of PCE.
If the HRIA source is removed and dissolved concentrations are reduced by 85 percent, the
eventual maximum plume length in the shallow aquifer is unlikely to reach active drinking
water sources and will eventually be remediated through natural attenuation, including physical
advection of dissolved PCE in groundwater, chemical dispersion, and simultaneous dilution.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
-------
Section 5 • Contaminant and Transport •
For the purposes of groundwater modeling, biodegradation was not considered to be a natural
attenuation process at the Site. Incorporating dilution and dispersion properties, the numerical
model predicted that most of the modeled (HRIA) plume would naturally attenuate through
dilution and dispersion within 30 years. Under a Source Removal Alternative, the model
predicted PCE concentrations at the release area would decrease to below 5 (ig/L within 5
years.
Modeling results showed that only a minor amount of the PCE concentrations detected in
groundwater at MW-25 (located about 2,400 feet downgradient of Labree Road, the Breen
Property, and Thurman Berwick Creek Area source areas) were associated with the HRIA
source area. This emphasized a need for additional investigations and further delineation of the
Breen and Thurman Berwick Creek Area source areas.
The model estimated that groundwater flow discharges to Dillenbaugh Creek downgradient
from the Site properties near the current mapped limit (based on field data) of the plume.
|
Under the No Action Alternative, the groundwater plume was estimated to expand slightly at |
the lateral extents and migrate to Dillenbaugh Creek near the plume's leading edge. j
Under the Source Removal Alternative, PCE concentrations in groundwater are expected to
drop below 5 (ig/L in the treatment area within 5 years after the source is removed and
treatment area concentrations are reduced by 85%.
5.4.1.3 Geostatistical Modeling
Three-dimensional geostatistical modeling was completed by CDM using Environmental Visualization
Software (EVS) [CDM 2009], This modeling was used, in part, to help identify possible areas of the
site where available groundwater data was insufficient to adequately characterize the area. To assist in
assessing site-wide data gaps, uncertainty plots were created using EVS and presented in the Study
Limitations Technical Memorandum (Appendix C).
This modeling pointed to the following areas with the greatest degree of uncertainty:
The area west of the Thurman Berwick Creek area, east of PW-21, and south of RS-49
The downgradient area west and northwest of the Breen Property and Thurman Berwick Creek
area, including the area around and downgradient of MW-25
5.4.2 Modeling Limitations
The Biochlor and numerical modeling efforts used important inputs that are not fully representative of
actual Site conditions. For instance, in the case of the Biochlor models, the groundwater gradient used
was double the observed Site gradient over most of the plume and the model did not account for
vertical gradients or seasonal shifts in gradients. The three-dimensional numerical model used a
hydraulic conductivity at least an order of magnitude higher than has been generally observed in order
to conservatively evaluate contaminant plume migration. Additionally, none of the models were able to
reproduce the observed downgradient plume, either in the length or the width of the >500 (ig/L plume
core west of Labree Road. The HRIA models were unable to reproduce or explain the relatively low-
concentration zone between the United Rentals Property and the Thurman Berwick Creek/Breen wash-
down pad areas. Consequently, they both overpredict concentrations from the HRIA downgradient of
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
58
-------
Section 5 • Contaminant and Transport •
that zone by about an order of magnitude. As for the Breen Biochlor model, not enough is known about
the original source, particularly its strength over time, to input a defensible source term. Since the
HRIA source cannot account for a large proportion of the contamination extending downgradient from
Labree Road, the Breen Property and/or Thurman Berwick Creek Area sources must account for more
of the downgradient plume than the Farallon Biochlor model estimates.
The three-dimensional numerical modeling, besides ignoring the Breen Property and Thurman Berwick
Creek Area sources, advanced (and attenuated) the groundwater contamination too quickly,
consequently providing an overly optimistic prediction of downgradient plume attenuation associated
with removing the HRIA source. Moreover, contaminant diffusion and back diffusion from aquifer
materials immediately downgradient of the HRIA source were ignored, resulting in an overly optimistic
prediction of plume attenuation near the head of the HRIA plume following source removal or
containment. However, the water-balance portion of the model provides insight into how the plume
may interact with Berwick and Dillenbaugh Creeks within the model domain. It predicted groundwater
discharge to Dillenbaugh Creek in the reach just below the confluence with Berwick Creek. Surface
water sampling in that reach in 2007 showed concentrations of PCE that indicate likely discharge of the |
northeastern edge of the plume in that area. !
When evaluating EVS modeling output, the user should consider data limitations and other factors that
increase the uncertainty associated with that output. This uncertainty may contribute to under- or
overestimation of mass, area, and/or volumes. For example, if data are sparse and/or clustered, the EVS
model may expand contamination to areas where there is a lack of bounding data and significantly
overestimate mass. In contrast, the EVS model has limited ability to consider groundwater flow paths,
which means it will not extrapolate or connect portions of a plume. This can result in an
underestimation of mass. Further, the model's limited ability to consider flow gradients means that it
may inappropriately assign mass in upgradient and cross gradient directions leading to an
overestimation of actual contaminant mass.
In addition, the user should also consider uncertainty associated with the analytical data used in the
various models due to data quality issues or limits associated with the analytical methods themselves.
There may be soil data quality issues stemming from soil sampling/preserving methodologies because
EPA Method 3035 was not used during soil sampling. As a result, there may have been a significant
loss of volatiles from the soil samples, especially the deeper gravely soils, thus biasing soil analytical
results and resulting PCE mass estimates low. Alternately, high detection limits for nondetect results
potentially lead to a high bias, e.g., the EVS model assigns a value of one half the detection limit to
represent nondetect results. Initial runs of the EVS model showed contamination extending under and
east of 1-5 because of high detection limits associated with samples collected from locations east of 1-5.
These results were subsequently removed from consideration. In summary, data and information
derived from the modeling effort should be considered in conjunction with known Site conditions to
minimize the impact of uncertainty attributed to model and data limitations.

Section 6
Baseline Risk Assessment Summary
The Baseline Risk Assessment Report (BRA) for the Site is included as Appendix G. A
summary of the baseline risk assessment results is included below. The BRA was conducted
in accordance with federal and regional Superfund technical guidance for human health (EPA
1989, 1991a, 1991b, 1992, 1996, 1998a, and 2004 in Appendix G) and ecological risk
assessment (EPA 1997b, 1997c, 1998b and in Appendix G). The BRA included an
evaluation of the two areas where releases of hazardous wastes are known to have occurred:
the HRIA and the Breen Property. In addition, the BRA evaluated areas downgradient from
the HRIA and cross-gradient from the Breen Property. The downgradient area includes the
Thurman Berwick Creek Area and the areas west of Labree Road. The BRA had the
following objectives:
Evaluate the risks associated with exposure of human and ecological receptors to
chemicals detected in groundwater, soil, sediment, surface water and indoor and
ambient air at the HRIA and the Breen Property.
Evaluate the risks associated with exposure of human and ecological receptors to
chemicals detected in groundwater, indoor air and ambient air downgradient of the
HRIA and the Breen Property.
Evaluate the risks associated with exposure of human and ecological receptors to
chemicals detected in surface water and sediments in Berwick Creek associated with
the HRIA and the Breen Property, and surface water in Dillenbaugh Creek
(downstream of Berwick Creek).
Existing environmental data, including groundwater and surface water data collected in July
2007 and indoor and outdoor air data collected in November 2007, were reviewed to
determine COPCs. Chemical concentrations were summarized for five Site locations (areas
upgradient of the HRIA, the HRIA, the Breen Property, downgradient areas, and Berwick and
Dillenbaugh Creeks) and compared to risk-based screening benchmarks for human and
ecological health. The following COPCs related to human health at the HRIA, Breen
Property, downgradient areas, and Berwick and Dillenbaugh Creeks were identified from the
risk screening and evaluated in the BRA:
• PCE
• TCE

No COPCs were identified for the areas upgradient of the HRIA.
The following COPCs were evaluated for ecological risk:
• PCE
• TCE

For both human health and ecological risk, petroleum hydrocarbons (gasoline and heavier fractions)
were retained as presumptive primary COPCs. These constituents will be further assessed once
sufficient data are obtained.
6.1 Summary of the Human Health Risk Assessment
The human health risk assessment examined several exposure pathways that were considered
potentially complete for receptors working at the HRIA or the Breen Property or for residents living in
downgradient areas. As shown on the conceptual site model included as Figure 6-1, the exposure
pathways evaluated include:
HRIA and Breen Property:
Indoor commercial/industrial worker:
Incidental soil ingestion and dermal contact (current/future).
Inhalation of vapors from the subsurface (groundwater and soil) in outdoor or indoor air
(current/future).
Ingestion of groundwater in the shallow aquifer as drinking water (future).
Inhalation of VOCs from groundwater vapors while showering (future).
Construction/utility worker:
Incidental soil ingestion and dermal contact (current/future).
Inhalation of vapors from the subsurface (groundwater and soil) in outdoor air (current/future).
Inhalation of vapors in a trench from groundwater at three subareas within the HRIA
(current/future).
Ingestion of groundwater in the shallow aquifer as drinking water (future).
Potential Trespasser
Incidental soil ingestion and dermal contact (current/future).
Inhalation of vapors from the subsurface soil in outdoor air (current/future).
Downgradient Areas:
Resident receptor (adult and child):
Inhalation of vapors from the subsurface (shallow groundwater) in indoor and outdoor air
(current/future).

Inhalation of VOCs from groundwater vapors while showering (future).
Berwick Creek/Dillenbaugh Creek:

Incidental ingestion and contact with surface water or sediments during recreation in Berwick
Creek and/or Dillenbaugh Creek.
¦ Ingestion of fish taken from Berwick or Dillenbaugh Creek.
The estimated noncancer and individual excess lifetime cancer risks to the aforementioned receptors are
summarized below:
HRIA Commercial/Industrial Worker: Noncancer hazards and cancer risks were estimated for a
long-term commercial/industrial employee working at either the main building or maintenance building
of the United Rentals property located at the HRIA. Exposure to contaminants in soil (incidental
ingestion, contact, and volatilization to outdoor air) and groundwater (drinking, vapors during
showering, and volatilization to indoor air) were evaluated. Under current use scenarios (indoor and
ambient air inhalation and soil contact and ingestion), HQs and individual excess lifetime cancer risks
were less than 1 and less than 8xl0"5, respectively. If chemical concentrations persist in groundwater
and it is used as a drinking water source in the future, estimated noncancer hazard indices would be
elevated (HI = 55-65) and individual excess lifetime cancer risks would be approximately lxlO"1 (i.e., a
10% probability of an excess cancer risk). Noncancer and cancer risks were primarily driven by PCE
concentrations found in groundwater (i.e., the drinking water pathway). Because the total risk from
exposure to contaminated soil for commercial/industrial worker in the HRIA is 8xl0~5; which is higher
than MTCA C acceptable cancer risk level of 1 x 10"5, the soil pathway may pose the most current risk
to individuals who work in this area.
HRIA Construction/Utility Worker: Noncancer hazards and cancer risks were estimated for a short-
term employee working at the HRIA. Exposure to contaminants in soil (incidental ingestion, contact,
and volatilization to outdoor air) and groundwater (drinking and volatilization to trench air) were
evaluated. Outdoor air and soil HQs and individual excess lifetime cancer risks were less than 1 and
less than lxlO"5, respectively, under current use scenarios. If chemical concentrations persist in
groundwater and it is used as drinking water source in the future, estimated noncancer hazard indices
would be 4.4 and estimated individual excess lifetime cancer risks would be approximately 3xl0"4.
Based on a model that estimates COPC concentrations in trench air from groundwater at three HRIA
subareas, estimated noncancer hazard indices ranged from 1.3 to 121 and estimated individual excess
lifetime cancer risks ranged from 4xl0"5 to 2xl0"3. Noncancer and cancer risks from a possible future
drinking water pathway were primarily driven by PCE concentrations found in groundwater, while the
estimated cancer risks from trench exposures were driven by both PCE and TCE. Based on trench air
concentrations that were modeled (estimated) from groundwater concentrations in three subareas of the
HRIA, construction or utility workers may be at substantial risk from inhalation of VOCs if exposed for
a sufficient duration without any personal protection. This assessment assumed a total exposure of 500
hours over the course of one year. Given the high risk estimates (individual excess lifetime cancer risks
up to 2x10~3 and a noncancer hazard index up to 121), even the assumption of a much lower exposure
duration by workers in HRIA subarea trenches would have resulted in estimates of unacceptable risk.
However, the accuracy of the model for estimating VOC concentrations in trench air from groundwater

-------
Section 6 • Baseline Risk Assessment Summary •
concentrations has not been validated for the Site and this represents a large uncertainty. If trenching
does occur in these subareas in the future, it is recommended that workers use appropriate personal
protection and/or air concentrations of VOCs in the trench(es) should be analytically verified to refine
the risk estimates.
Breen Commercial/Industrial Worker: Noncancer hazards and cancer risks were estimated for a
long-term commercial/industrial employee working at one of four buildings (A, B, C, and Livestock
Auction) on the Breen Property. Exposure to contaminants in soil (incidental ingestion, contact, and
volatilization to outdoor air) and groundwater (volatilization to indoor air, drinking, and showering)
were evaluated. Soil, outdoor air, and indoor air HQs and individual excess lifetime cancer risks were
less than 1 and less than lxlO"5, respectively, under current use scenarios. If chemical concentrations
persist in groundwater and it is used as drinking water source in the future, estimated noncancer hazard
indices would be slightly elevated (HI = 1.5) and estimated individual excess lifetime cancer risks
would be approximately 3xl0"3. Noncancer hazards and cancer risks were primarily driven by PCE
concentrations found in groundwater (i.e., drinking water pathway). Thus, the current concentrations of
VOCs, particularly PCE, have the potential to result in increased health risks to people drinking |
contaminated groundwater and working long-term at the Breen Property. However, the buildings at the !
Breen Property are currently using municipal water sources rather than local groundwater sources for j
drinking water.
Breen Construction Worker: Exposure to contaminants in soil (incidental ingestion, contact, and
volatilization to outdoor air) and groundwater (drinking) were evaluated. Outdoor air and soil HQs and
individual excess lifetime cancer risks were more less than 1 and less than lxlO"5, respectively, under
current use scenarios. If chemical concentrations persist in groundwater and it is used as drinking water
source in the future, estimated noncancer hazard indices would be less than 1.0 and estimated individual
excess lifetime cancer risks would be approximately 9xl0~6. Noncancer hazards and cancer risks were
primarily driven by PCE concentrations found in groundwater (i.e., drinking water pathway). Based on
the risk estimates derived for current use, it appears that contaminants detected in soil, as well as
outdoor air do not pose unacceptable risks to construction workers in the Breen area.
HRIA and Breen Potential Trespasser: Individual excess lifetime cancer risks to a construction or
utility worker at the HRIA or Breen area were based on the assumption that a construction worker could
work at the Site for twenty eight-hour days for one year, and excess individual lifetime cancer risks due
to exposures to outdoor air and soil are estimated to be less than lxlO"6. Given the potential trespasser
exposures would likely be less frequent and of shorter duration, cancer risks to a trespasser would also
be less than lxlO"6.
Downgradient Residents: Indoor air samples were collected at six downgradient residences, one of
which also operates as a commercial business. Estimated noncancer hazards were all below 1.0 and
estimated total individual excess lifetime cancer risks ranged from 6.9 x 10-7 to 4.7 x 10-6 (Table 2-
10a). For the majority of the residences, TCE contributed the most to the total individual excess lifetime
cancer risk. Overall, excess cancer risks from inhalation of indoor air at the six locations do not exceed
1 x 10-5.
Noncancer hazards and cancer risks were evaluated for a number of downgradient groundwater wells,
representing a range of exposure for potential future single-family residences (under a scenario where
future residences obtain their water from wells, rather than municipal water supply, and COPC
concentrations in groundwater are unchanged). Risks were evaluated for children and adults using the
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
63

Section 6 • Baseline Risk Assessment Summary •
groundwater system for domestic use (pathways include drinking water, showering). Estimated
noncancer risk (ingestion and dermal pathways, all COPCs) for children ranged from 24.75-49.97.
Estimated noncancer hazards (ingestion and dermal pathways, all COPCs) for children ranged from 25
to 50 and for adults ranged from 7 to 13 Individual excess lifetime cancer risks for children varied by
groundwater well and ranged from lxlO"2 to 2xl0"2. Individual excess lifetime cancer risks for adults
varied by groundwater well and ranged from 2xl0"2 to 3xl0"2. Thus, depending on the well, current
groundwater concentrations indicate the potential for increased health risks (primarily from drinking or
showering pathways) to future residents living downgradient of the HRIA and the Breen Property if the
COPC concentrations persist and groundwater is used as a drinking source rather than the municipal
water supply. As discussed previously, those wells located at residences downgradient of the water
supply line do not show signs of contamination or risks under current use exposures.
Berwick Creek and Dillenbaugh Creek Recreator: Noncancer and cancer risks were estimated for
adults and children recreating infrequently at Berwick Creek or Dillenbaugh Creek. Exposure to
contaminants in surface water (incidental ingestion and contact) and sediment (incidental ingestion and
contact) were evaluated. At Berwick Creek, estimated noncancer hazard indices for both adults and
children were less than 1.0. The estimated individual excess lifetime cancer risks were approximately
2x10~4 for the HRIA (both adults and children) and 7x10~6 and 2x10~6 for adults and children,
respectively, for the downgradient areas. Individual excess lifetime cancer risks were predominantly
driven by PCE concentrations identified in sediment associated with the HRIA in Berwick Creek. At
Dillenbaugh Creek, hazard indices were less than 1.0 and the estimated cancer risks were lxl0"6 and
4x10~7 for adults and children, respectively (due to the lack of sediment chemistry data for Dillenbaugh
Creek, downgradient sediment concentrations for Berwick Creek were assumed).
The screening level assessment for anglers that may consume fish taken from Berwick or Dillenbaugh
Creeks shows that surface water concentrations of PCE in these creeks exceed surface water screening
concentrations that correspond to a cancer risk of 10"6 or a hazard index of 1.0. Concentrations of TCE
and methylene chloride do not exceed their screening level benchmarks.
6.2 Summary of the Ecological Risk Assessment
The ecological risk assessment examined several exposure pathways that were considered potentially
complete for ecological receptors living or visiting the Site. As shown on the conceptual site model
included as Figure 6-1, the exposure pathways evaluated include:
HRIA, Breen Property, and Downgradient Areas: Birds and mammals were evaluated for incidental
ingestion of contaminants in soils located at the HRIA. In addition, burrowing mammals (shrew) were
evaluated for inhalation of volatile organics in burrow air. Terrestrial plants were evaluated for uptake
of contaminants in groundwater and soils.
Berwick Creek/Dillenbaugh Creek: Birds (bald eagle, American robin, and mallard duck) and
mammals (shrew, raccoon, and white-tailed deer) were evaluated for incidental ingestion of
contaminants in surface water and sediment. Salmonids were evaluated for direct contact with surface
water.
The estimated risks to ecological receptors are summarized below.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
64
-------
Section 6 • Baseline Risk Assessment Summary •
Wildlife
Avian Receptors (Bald Eagle, American Robin, and Mallard Duck): No elevated risks for bald eagles
were identified for any COPCs at any of the locations evaluated. However, American robin risks were
elevated for PCE from ingestion of soils, surface waters, and sediments at all Site locations (HQs =1.3
to 11). Mallards had slightly elevated HQs (3.0) for PCE at the HRIA and the Breen Property. The risks
to robins and mallards are primarily due to their high soil/sediment ingestion rate and the elevated PCE
concentrations identified in Berwick Creek sediments.
Mammalian Receptors (Shrew, Raccoon, and Deer): Mammalian receptors were evaluated for
incidental ingestion of Site soils, Berwick Creek surface water and sediments, Dillenbaugh Creek
surface water, and inhalation of volatiles from Site soils (shrews only). Elevated risks were found for
shrews at the HRIA from ingestion of PCE in soils, surface water or sediment (HQ = 1.2) and
inhalation of PCE in burrows (HQ = 50). Elevated risks were also identified for PCE at the Breen
Property from inhalation of VOCs in burrow air (HQs = 1.3 to 6.8). Raccoons (HQs = 8.5 to 43) and
deer (HQs = 1.2 to 6.6) had elevated HQs for PCE at the HRIA and the Breen Property. Ingestion of (
|
PCE in soils, surface water, and sediments in the downgradient areas did not indicate an elevated risk to |
any mammalian receptor (HQs < 1.0). Ingestion risks were primarily driven by the high PCE j
concentrations found in Berwick Creek sediments associated with the HRIA.
Aquatic Life
Aquatic receptors (e.g., salmonids) were evaluated for direct contact to chemicals in surface waters of
Berwick Creek and Dillenbaugh Creek. Current concentrations of cis-l,2-DCE, PCE, and TCE are not
expected to result in elevated risks to aquatic organisms.
Terrestrial Plants
Minimal risks were quantified for terrestrial plant receptors at all Site locations, with the exception of
PCE in groundwater at the HRIA area (HQ = 7.3).
6.3 Conclusions of the Baseline Risk Assessment
The following are the general conclusions from the Hamilton/Labree Roads BRA:
The overall results of the human health risk assessment indicate that current contaminant concentrations
(predominantly PCE) in groundwater represent a potential for adverse risks to future Site workers and
downgradient residents if the plume persists and groundwater is used for domestic purposes. Currently,
these receptors are either connected to the municipal water system or are not currently affected by the
contaminated groundwater plume. In addition, construction or utility workers potentially working in a
trench at the HRIA may be at unacceptable risk from inhalation of VOCs based on trench air
concentrations estimated from groundwater concentrations; however, the estimated trench air
concentrations have high uncertainty. Nevertheless, as a precaution, it is recommended that workers use
appropriate personal protection if trench work is required (or VOC concentrations in trenches should be
analytically verified prior to commencement of work). The total estimated individual excess lifetime
cancer risks for commercial/industrial workers at the Breen area slightly exceed the risk threshold under
MTCA C. However, the exceedance is not significant and suggests that contaminants at the Site would
not pose any appreciable individual excess lifetime risk to commercial/industrial workers. Estimated
risks from the volatilization of contaminants in groundwater to indoor air are below the risk threshold
level at the HRIA and the Breen Property, as well as downgradient residences. However, additional
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11

Section 6 • Baseline Risk Assessment Summary •
indoor air sampling is necessary to refine the indoor air inhalation risk estimates. Recreational activities
at Berwick Creek are anticipated to be of minimal concern if conducted away from the primary PCE
spill source at the HRIA.
The overall results of the ecological risk assessment indicate that current contaminant concentrations of
PCE in subsurface soils and sediment associated with the HRIA spill area may represent a potential for
elevated risks to organisms. The potential risk estimates for ecological receptors can be refined in
further evaluations because (1) highly conservative exposure estimates were utilized in this BRA, and
(2) the HRIA spill area is generally confined to a small area within Berwick Creek, although PCE (but
not the other COPCs) was detected in Dillenbaugh Creek surface water.
Overall, PCE and associated VOC risks are localized in groundwater, soils, and sediments. Domestic
use of groundwater is the primary concern at the Site (i.e., HRIA and Breen Property, and downgradient
areas) and institutional controls (i.e., use of municipal water systems rather than groundwater sources
and restricted access to the HRIA and Breen Property) will minimize exposure to contaminants
associated with the HRIA and the Breen Property. The potential inhalation risks from VOCs,
particularly PCE and TCE, in trenches at select subareas of the HRIA are also of concern and necessary
institutional controls (e.g., personal protection) should be considered to reduce exposures via this route
(or trench air concentrations could be empirically determined to refine the risk estimates before workers
spend time in a trench).
Due to the uncertainties and limitations summarized in the Sections 2.4.2 and 3.5.4 of the Draft
Baseline Risk Assessment Technical Memorandum, and as detailed in the Section 7.5 of this remedial
investigation report, additional sampling and analysis will need to be conducted across the Site. This is
especially true for contaminated groundwater in the upper portion of the shallow aquifer and the
potential risks from vapor intrusion. Additional characterization of the HRIA will be completed after
an interim Record of Decision is implemented for this source area. Characterization of the rest of the
Site will be completed separately from the HRIA during continued remedial investigations culminating
in a separate and final Record of Decision for the Site. As new information is obtained, new risk
assessments will be performed.

Section 7
Summary and Conclusions
This RI report focuses mainly on the contamination originating at the HRIA. The Breen
Property, Thurman Berwick Creek Area, and the downgradient areas have not yet been fully
characterized. A separate RI report will be prepared for these other areas. This report,
however, does include information on the investigations and data results from these three
other areas to better understand Site-wide groundwater contamination, especially
contamination attributable to the HRIA.
This section focuses on the characteristics, migration, and potential impacts of the HRIA
contamination, and it provides a summary of the findings of the RI and conclusions based on
these findings. However, Section 7.5 (Recommendations for Future Actions) includes
recommended future investigations for the other areas of the Site that will help to better
understand downgradient migration of the groundwater plume from the HRIA and interactions
with the plumes originating from other Site areas.
7.1 Contamination Summary
The COPCs across the Site are PCE and its degradation products TCE, cis-l,2-DCE, and vinyl
chloride, and the chemicals tetrahydrofuran and methylene chloride. PCE has been detected
more frequently and at much higher concentrations than the other COPCs, and it is the
primary risk driver according to the BRA. Therefore, for the purpose of discussing
contamination at the Site, PCE is the indicator or primary COPC. Petroleum hydrocarbons
(gasoline and heavier fractions) are also considered a presumptive COPC until proven
otherwise.
7.1.1 Soil
Soil depths have been divided into three categories for purposes of delineating PCE
contamination: surface, near surface and subsurface. In general, surface soils at this Site are
defined as 0 to 5 feet bgs and near surface soil at 5 to 10 feet bgs. Subsurface soils exist at
depths greater than 10 feet to typically the top of the aquitard at 50 feet bgs.
7.1.1.1 Surface and Near Surface Soils
Currently, the only identified surface/near surface soil source of PCE in groundwater is creek
bed sediment/soil in the HRIA (Section 7.1.5). Only minor surface soil contamination has
been identified at the Breen Property.
No surface or near surface soil samples from the Thurman Berwick Creek Area or
downgradient areas west of Labree Road contained detectable PCE concentrations.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11

-------
Section 7 • Summary and Conclusions •
Additional investigations are required at the Breen Property to attempt to identify the source of
groundwater contamination, which may include unidentified surface or near surface soil contamination.
A technical memorandum describing data gaps related to the Breen Property is presented in
Appendix C.
7.1.1.2 Subsurface Soil
The highest concentrations of PCE were detected in subsurface soil at the HRIA and appeared to be
directly related to PCE DNAPL (based on the high PCE concentrations) in subsurface soils beneath the
apparent PCE release in Berwick Creek. Only minor subsurface concentrations of PCE have been
detected in subsurface soils at the Breen Property.
Available subsurface soil data for the Thurman Berwick Creek Area and downgradient areas west of
Labree Road are limited. PCE has been detected in soil at four locations in the Thurman Berwick Creek
Area with a maximum concentration of 1.3 mg/kg. Soil data are available for one boring located west of
Labree Road (MW-25) where there was a maximum detected concentration of 0.13 mg/kg in a sample
from 40 feet bgs. PCE was not detected in shallower samples.
Additional investigations are required at the Breen Property to attempt to identify the source of
groundwater contamination, which may include unidentified subsurface soil sources.
7.1.2 Groundwater
At the HRIA, the primary source of PCE in groundwater is where PCE was spilled or released to
Berwick Creek in the Southeastern Hot Spot (Figure 4-1). Based on high PCE concentrations, DNAPL
is inferred to exist in the shallow aquifer beneath the apparent release location to a depth of
approximately 35 feet. Additional investigations are required to identify remaining sources for the
shallow aquifer PCE contamination at the Breen Property and the downgradient extent of the associated
groundwater plume.
PCE concentrations greater than 1,000 (ig/L have been detected in groundwater samples collected from
private well PW-9 and in shallow groundwater samples collected from several monitoring wells located
in the Thurman Berwick Creek Area downgradient of, and adjacent to, Berwick Creek. Because PCE
concentrations have been identified in shallow groundwater, a local source of contamination is
probable.
Based on the groundwater modeling completed for the Site, the plume emanating from the HRIA is
estimated to end approximately 500 feet west of Labree Road, assuming the release into Berwick Creek
did not occur much before 1990. If so, the majority of the downgradient groundwater plume west of
Labree Road most likely originated from the Breen Property and the Thurman Berwick Creek Area.
Moreover, a north-south zone east of where North Hamilton Road crosses Berwick Creek, between RS-
2 and RS-24, appears to act as a vertical PCE transport "bottleneck", where significant amounts of PCE
transport in the upper zone of the shallow aquifer to the Breen Property and the Thurman Berwick
Creek Area is limited. Within this zone, the upper 20 feet of the shallow aquifer has little to no PCE
contamination. Therefore, the PCE contamination in the upper portion of the aquifer west of this north-
south zone could not have come from the HRIA. PCE concentrations in lower portions of the shallow
aquifer in the Thurman Berwick Creek Area reflect mixing between deeper groundwater contamination
from the Breen Property or upgradient Berwick Creek sources and deeper groundwater contamination
from the HRIA.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
68
-------
Section 7 • Summary and Conclusions •
Currently, the extent of the PCE groundwater plume downgradient of the Breen Property and the
Thurman Berwick Creek Area west of Labree Road is unknown. In contrast to the area between United
Rentals and the suspected Breen and Thurman Berwick Creek source areas, PCE concentrations in the
core of this portion of the plume decline very little with distance, suggesting that the plume could
extend much further downgradient than currently observed. In addition, the plume edges in the
downgradient area west of Labree Road have not been adequately established, particularly on the
northeast edge parallel to 1-5.
Additional investigations are needed to define the extent of groundwater contamination.
7.1.3 Surface Water
Surface water data indicate that concentrations of PCE in surface water do not pose a risk to aquatic
receptors within Berwick Creek or Dillenbaugh Creek. The source of the PCE detected in surface water
samples collected at several stations may be residual contamination that is dissolving from PCE
entrained in the creek bed sediment/soil.
S;
No surface water sampling has been completed in Berwick Creek in the northern portion of the HRIA |
between MW-R4 and MW-5/MW-33. High PCE concentrations have been detected in upper zone wells j
MW-R3 (Northwestern Hot Spot) and MW-33. It is unknown if contaminated groundwater related to
these areas is potentially discharging to surface water in this area.
Surface water sampling in Dillenbaugh Creek in July 2007 indicated that PCE is present in surface
water. The concentrations are most likely related to discharge of PCE-contaminated groundwater to
Dillenbaugh Creek. The extent of the groundwater plume is unknown, and if the centerline of the plume
crosses Dillenbaugh Creek, higher concentrations may discharge farther downstream. Additional
chemical data are necessary to adequately characterize impacts to surface water in the downgradient
areas.
7.1.4 Creek Bed Sediment/Soil
Creek bed sediment/soil contamination appears to be primarily confined to the HRIA and an area
immediately downstream of this location. PCE DNAPL has been identified in a silt layer beneath the
Berwick Creek bed. This layer likely provides a continuing source of PCE to groundwater.
No creek bed sediment/soil samples have been collected from Berwick Creek in the northern portion of
the HRIA, particularly in the segment between MW-R4 and MW-5/MW-33 where there appears to be
another contamination source. It is unknown if there is a separate potential creek source for the
contamination detected in MW-33.
PCE concentrations up to 3,740 (ig/L have been detected in groundwater samples collected from private
well PW-9 located in the Thurman Berwick Creek Area downgradient of the portion of the HRIA
plume that exceeds 1,000 (ig/L. No source for the PCE in excess of 1,000 (ig/L in groundwater has been
identified (Section 4.3.3). A possible source for the contamination may be release(s) to Berwick Creek
south of the Breen Property immediately upstream of North Hamilton Road (near MW-30) and
downstream in the area of MW-32. Conceivably, PCE DNAPL flowed down Berwick Creek from the
HRIA release and settled into this reach, but the lack of evidence of DNAPL in the intervening creek
bed deposits makes this scenario highly speculative. Additional sampling of sediment/soil in Berwick
Creek in this area is necessary to assess if a release has occurred. A technical memorandum describing
data gaps related to this and other downgradient areas is presented in Appendix C.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
69
-------
Section 7 • Summary and Conclusions •
7.1.5 Indoor and Ambient Air Quality
Air sampling data collected from the Site showed low levels of PCE in the majority of the residential,
commercial, and ambient locations. However, the estimated risks from the volatilization of
contaminants in groundwater to indoor air are below the risk threshold level at the HRIA and Breen
Property, as well as downgradient residences.
Based on the results of investigations to assess the downgradient extent of upper zone groundwater
contamination (Section 7.1.2), additional air sampling and assessment of vapor intrusion may be
required at residences along Rice Road and other downgradient locations.
7.2 Results of Fate and Transport Analysis
In general, monitoring wells located downgradient of the HRIA release area continue to show an
increase in PCE concentration over time. Wells located at the upgradient edge of the release area (i.e.,
MW-9) or cross-gradient (i.e., MW-R11) have shown decreased concentrations with time. Biochlor
modeling suggests that the HRIA plume is likely to continue to migrate for some time even if PCE
concentrations in the release area are removed and the dissolved concentrations are reduced by 85
percent. The PCE remaining in groundwater will continue to attenuate through natural processes,
including physical advection of dissolved PCE in groundwater, chemical dispersion, simultaneous
dilution, and sorption to aquifer materials. Biodegradation is not considered to be a major natural
attenuation process at the Site, with the possible exception of contamination in the upper zone of the
shallow aquifer around Building B on the Breen Property. Based on the results of the modeling
completed using Biochlor, natural attenuation of the PCE concentrations remaining in groundwater will
require several hundred years near the HRIA release area.
PCE-contaminated groundwater appears to have discharged to surface water (Dillenbaugh Creek)
downgradient and cross-gradient of MW-25. It is not understood how contaminated groundwater
discharge to the creek is affecting the plume migration (i.e., is the majority of the PCE plume
discharging to the creek or continuing down the valley?). Additional data related to
groundwater/surface water interaction in the downgradient areas are needed to adequately characterize
impacts to surface water.
The evaluation of fate and transport is limited by an incomplete understanding of site conditions
including:
Horizontal and vertical gradients in and between the upper and lower zones of the shallow
aquifer
Seasonal variations in gradients
Depth-discrete variations in hydraulic conductivities and preferential pathways associated with
relatively higher-conductivity stratigraphic layers
7.3 Results of Risk Assessment
Overall, PCE and associated VOC risks are localized in groundwater, soil, and sediment. Domestic use
of groundwater is the primary human health concern at the Site (i.e., HRIA and Breen Property, and
downgradient areas) and institutional controls (i.e., use of municipal water systems rather than
groundwater sources and restricted access to the HRIA and Breen Property) will minimize exposure to
contaminants associated with the HRIA and the Breen Property. The potential inhalation risks from
VOCs, particularly PCE and TCE, in trenches at select subareas of the HRIA are also of concern, and
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
70
-------
Section 7 • Summary and Conclusions •
necessary institutional controls (e.g., personal protection) should be considered to reduce exposures via
this route (or trench air concentrations could be empirically determined to refine the risk estimates
before workers spend time in a trench).
The overall results of the ecological risk assessment indicate that current contaminant concentrations of
PCE in subsurface soil and sediment associated with the HRIA spill area may represent a potential for
elevated risks to organisms. However, risks to ecological receptors are ultimately considered to be
minimal because (1) highly conservative exposure estimates were used in the BRA, and (2) the HRIA
spill area is generally confined to a small area within Berwick Creek, although PCE (but not the other
COPCs) was detected in Dillenbaugh Creek surface water.
Due to the uncertainties and limitations related to data gaps for soil, groundwater, and surface water
analysis, additional sampling and analysis will need to be conducted across the Site. This is especially
true for contaminated groundwater in the upper zone of the shallow aquifer and the potential risks from
vapor intrusion, as well as the downgradient extent of the plume and whether it discharges to surface
water.
7.4 Study Limitations
The limitations of this RI range from data gaps affecting the ability to delineate the magnitude and
extent of PCE contamination to gaps in the fundamental understanding of the Site which could
significantly alter the CSM. Resolution of some of these issues could require information that may
never be available (e.g., historical information regarding activities in source areas).
7.4.1 Conceptual Limitations
Investigations at the Site have not been sufficient to explain basic contaminant migration relationships
and processes, including:
Determining the nature, age, and location of all sources contributing to the Site-wide
contaminant plume.
Explaining the large spatial differences in source-to-plume mass-transfer processes, both
vertically and horizontally, as evidenced by the apparent "bottleneck" downgradient of the
HRIA (Figure 4-5), which is in sharp contrast to the much lower rate of contaminant decline
with distance downgradient of Labree Road.
Delineating the fate and limits of the Site plume as it extends beyond RS-20, particularly,
whether it discharges to surface water.
Understanding site hydraulic conditions including:
o Horizontal and vertical gradients in and between the upper and lower zones of the
shallow aquifer
o Seasonal variations in gradients
o Depth-discrete variations in hydraulic conductivities and preferential pathways
associated with relatively higher-conductivity stratigraphic layers within the shallow
aquifer
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
-------
Section 7 • Summary and Conclusions •
Delineating the impacts of contamination in the deep aquifer within the HRIA, Breen Property,
and Thurman Berwick Creek Areas.
¦ Evaluating the relative contribution from the HRIA, Breen Property and/or Thurman Berwick
Creek Area contaminant sources on contaminant mass loading to the Site-wide contaminant
plume.
Additional characterization can resolve some of these issues, while others will require more
sophisticated analysis. For example, a stable isotope study may be conducted to attempt to distinguish
between the PCE from the HRIA, the Breen Property, and the Thurman Berwick Creek Area.
Analyzing for tentatively identified compounds (TICs) may also be useful to distinguish PCE from
different disposal sources if the PCE was used for different purposes and contained different additives
and stabilizers. This study may also provide information on how the groundwater plume is migrating
through the Site and help resolve the following data gaps:
¦ Whether the PCE at the Thurman Berwick Creek Area is related to the HRIA release or
associated with the Breen Property contamination.
The extent of PCE related to the HRIA source in the deeper portion of the plume downgradient
of Labree Road.
The source of PCE detected in private well PW-21.
7.4.2 Data Limitations
The data used to develop this RI report were collected during numerous investigations conducted at the
Site between 1993 and 2007. In several cases, conclusions developed by the entity that collected and
interpreted the original data were used to complete this RI. This was primarily true for the data and
interpretation completed for the HRIA as described in the EE/CA (URS 2004).
Based on review of historical data, soil samples collected at the Site for VOC analysis do not appear to
have been collected and preserved using the protocols under EPA Method 5 03 5A with the exception of
the sampling done in the HRIA in 2003 for the EE/CA (URS 2004). The primary goal of this VOC
collection and preservation technique is to minimize the direct volatilization of contaminants in soil to
the atmosphere. Since EPA Method 5035A does not appear to have been used during soil sample
collection at either the Breen Property or the Thurman Berwick Creek Area, there is a strong probability
that VOC analytical results are biased low for those areas, especially for samples collected from the
gravelly materials that comprise the shallow aquifer.
A large body of groundwater data exists for the Site, but it is unevenly distributed, both horizontally
and vertically. For example, little data are available in the plume downgradient of Labree Road.
Vertically, the data come from a wide mix of screened-interval lengths, including: 1) 1-foot intervals in
temporary borings, 2) monitoring wells with conventional 10-foot screens, 3) monitoring wells
screened across the entire shallow aquifer, and 4) private wells of unknown construction. Consequently,
data interpretation requires subjective judgments as to which data should be honored, emphasized, or
disregarded.
The most recent groundwater monitoring and sampling data collected at the Site were used to assess
groundwater flow and plume migrations. The last extensive groundwater sampling occurred at the Site

72
-------
Section 7 • Summary and Conclusions •
in November 2003. These 2003 groundwater data were supplemented with the results of a limited
groundwater sampling event conducted in July 2007 to assess the current PCE plume movement
throughout the Site.
Creek channel samples CC-1 through CC-9 were collected by Farallon (2004) from Berwick Creek
south of the Breen Property. The samples were collected from the creek bed at approximately 1 foot
bgs. Based on available sample collection information, it is unclear whether these samples were
collected from sediment accumulations in the creek channel or if the samples were collected from the
silt layer that composes the creek bottom. Based on the creek bed sampling results for the HRIA (URS
2004), the PCE concentrations were mainly detected within the silt layer. Creek bed samples CC-1
through CC-9 may not represent the actual PCE concentration in the Berwick Creek bed near the Breen
Property.
Limited data regarding groundwater and surface water interaction were available downgradient of the
Breen Property. Surface water data were collected in July 2007 from Dillenbaugh Creek, but were
limited to two samples.
7.5 Recommendations for Future Actions
A summary of recommended future actions at the Site is presented below. Additional details are
presented in Technical Memorandum: Revision 4 Final Hamilton/Labree Roads Study Limitations
Analysis (EPA 201 lb) contained in Appendix C.
Site-Wide
Conduct aquifer testing in the area downgradient of the United Rentals facility and
downgradient and west of Labree Road to better define Site-wide hydraulic conductivity.
Evaluate depth-discrete variations in hydraulic conductivities and preferential pathways
associated with relatively higher-conductivity stratigraphic layers within the shallow aquifer by
conducting aquifer testing within temporary boreholes and completed wells screened at discrete
depths within the aquifer and including information in numeric and 3D EVS modeling.
Evaluate horizontal and vertical hydraulic gradients Site-wide in and between the upper and
lower zones of the shallow aquifer and assess seasonal gradient shifts in direction by collecting
comprehensive gradient data at least quarterly for one year.
Collect soil core samples for analysis of porosity, density, and grain size to better define Site-
wide aquifer characteristics.
Conduct additional assessment and mapping of the Site-wide vertical distribution of PCE in
groundwater. In particular, contaminant characterization of the upper zone of the shallow
aquifer between the transport "bottleneck" and the Thurman Berwick Creek Area; in the lower
zone of the shallow aquifer between the United Rentals building and the transport "bottleneck,"
and vertical and horizontal plume transects from Labree Road to the end of the plume.
¦ Evaluate the relative contribution of the HRIA, Breen Property and/or Thurman Berwick Creek
Area contaminant sources on contaminant mass loading to the Site-wide contaminant plume by
evaluating mass discharge of contaminants from the proposed transects.
Sound the depth of private wells with no logs that are within the plume.

-------
Section 7 • Summary and Conclusions •
Conduct a stable isotope study, including analysis of TICs, to distinguish PCE from the HRIA.
the Breen Property, and the Thurman Berwick Creek Area.
Update Site-wide EVS modeling using newly acquired Site chemical and physical data and the
three dimensional modeling using newly collected aquifer parameters.
Install shallow piezometers within the stream bed along Berwick and Dillenbaugh Creeks to
measure head differences between the surface water of the creek and the groundwater within
the bed/or slightly below the bed of the creek in order to determine where gaining and losing
reaches of the creek exist and their influence on contaminant fate and transport.
Conduct additional indoor and ambient air sampling following completion of the remedial
action at the HRIA.
Since completion of the City water main extension in November 2002, production wells local
to the HRIA and Thurman Berwick Creek Areas have not been influencing the groundwater
flow regime. However, numerous water supply wells exist within a 4-mile radius of these sites
and may have some influence on gradient conditions recorded at the site during these historical |
investigations. This influence needs further characterization through analytical and/or j
numerical modeling efforts to enhance understanding of past and present pumping well
influence to plume migration and inform institutional controls, if needed, to maintain protection f
of existing potable water supplies.
Delineate the impacts of contamination in the deep aquifer within the HRIA, Breen Property
and Thurman Berwick Creek Areas by installing additional, deep monitoring wells. These wells
would need to be carefully installed using best practices to prevent contamination from the
shallow aquifer from migrating to the deep aquifer during and after well construction.
HRIA
Collect surface water samples in the section of Berwick Creek between approximately MW-R4
and MW-33. No surface water sampling appears to have been conducted in this length of
Berwick Creek.
Collect sediment/soil samples in the section of Berwick Creek between approximately MW-R4
and MW-33 to attempt to identify potential creek sources to groundwater contamination.
Collect depth-specific groundwater samples from the MW-600 series wells. If results indicate
significant downward migration of contamination, these wells should be abandoned.
Conduct pre-remedial design soil sampling to validate which VOCs and other contaminants
(such as petroleum hydrocarbons) are present and at what concentrations. The need for this
investigation would be assessed once a remedial alternative is selected and prior to remedial
design.
Conduct pre-remedial design groundwater sampling and analysis for petroleum hydrocarbons,
metals, SVOCs, and pesticides, especially at source areas.
"Bottleneck"
Conduct one to two north-south transects between MW-3 and MW-22/23. Groundwater
samples would be collected at four different intervals in each boring: a shallow interval (upper
5 feet of the aquifer), from approximately 15 to 25 feet bgs, from approximately 30 to 40 feet
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
-------
Section 7 • Summary and Conclusions •
bgs, and a deep sample from approximately 40 feet bgs to the bottom of the aquifer (typically
around 50 feet bgs).
Install borings to characterize and define the north and south ends of the "bottleneck" and south
of MW-24 to RS-24.
Install east-west centerline borings in both the northern and southern plume lobes to fill in
between north-south transects.
Install a transect extending east and west from the HRIA source area containing DNAPL
(Southeastern Hot Spot) to the Thurman Berwick Creek area. Collect lithologic information
and aquifer parameters. Groundwater sampling would be completed at the same intervals as
discussed for the two north-south transects between MW-3 and MW-22/23. Use information
from this transect to prepare a cross-section identifying conditions from the HRIA, through the
"bottleneck", and to the Thurman Berwick Creek Area.
Breen Property
Conduct a geophysical investigation in areas not previously investigated to attempt to locate
potential sources.
Conduct a subsurface investigation in the areas described in Section 4.3.2 and areas containing
geophysical anomalies that were not previously evaluated. Analysis would include VOCs and
petroleum hydrocarbons.
Install additional monitoring wells in areas identified by the subsurface investigation to better
assess the groundwater plume and its migration.
Install additional monitoring wells in the southeastern and central portions of the property to
evaluate a potential northern migration pathway from the HRIA.
Complete a round of groundwater sampling and analysis (including VOCs, petroleum
hydrocarbons, metals, field monitored parameters, and conventional chemistry analyses) that
would include newly installed wells and existing wells to obtain a current snapshot of the
groundwater plume at the Breen Property.
Soil samples collected from borings must be handled and preserved per EPA Method 5035A
and analyzed for VOCs and petroleum hydrocarbons.
Thurman Berwick Creek Area
Conduct additional sampling of sediment/soil in Berwick Creek between RS-46 and Labree
Road to attempt to identify potential creek sources for groundwater contamination in PW-9.
Soil samples collected for VOC analysis must be properly preserved per EPA Method 5035A.
Complete a north-south boring transect running south from boring B-8 to a line running from
MW-4 to MW-24. Collect soil and groundwater samples in the same manner as discussed for
the "bottleneck" area and Breen Property borings.
Downgradient Areas West of Labree Road
Install monitoring wells along the plume axis downgradient of the Breen Property between
Labree Road and MW-25 to better assess the groundwater plume and its migration.
Draft Final Hamilton/Labree Roads Remedial Investigation Report - 09/01/11
75
-------
Section 7 • Summary and Conclusions •
Install monitoring wells downgradient of MW-25 along the approximate plume axis, based on a
series of boring transects. Proposed well locations should include the area between MW-25 and
the suspected leading edge of the plume, at or near the leading edge of the plume, and between
the leading edge and a downgradient point(s) where the PCE concentration is not detectable.
Groundwater samples would be collected at four different intervals in each boring: a shallow
interval (upper 5 feet of the aquifer), from approximately 15 to 25 feet bgs, from approximately
30 to 40 feet bgs, and a deep sample from approximately 40 feet bgs to the bottom of the
aquifer (typically around 50 feet bgs).
Install subsurface borings and collect soil and groundwater samples between RS-47 and 1-5 to
assess the extent of the groundwater plume from the Breen Property.
Install subsurface borings and collect soil and groundwater samples in the high-uncertainty area
identified in the EV S modeling to the south of RS-49 to assess the extent of the apparent plume
from the Thurman Berwick Creek Area and to better assess the portion of the plume upgradient
of PW-21.
Collect surface water samples in Dillenbaugh and Berwick Creeks between Labree Road and
MW-28 to assess groundwater/surface water interaction. In addition, collect generally co-
located groundwater samples along Dillenbaugh Creek to evaluate the PCE concentrations in
groundwater potentially being discharged.
Depending upon the results of the soil/sediment sampling in the Thurman Berwick Creek Area,
collect sediment/soil samples in Berwick Creek between Labree Road and the confluence with
Dillenbaugh Creek to attempt to evaluate whether additional creek sources may exist.

Four phases of work as part of a time-critical removal action. Installed and sampled
temporary borings, monitoring wells, and combined monitoring and recovery wells.
All temporary and permanent sampling locations assessed the shallow aquifer, with
various sampling and screen depths. Evaluated removal action alternatives.
Implemented the alternative drinking water supply
alternative, connecting affected residences and
businesses to the City of Chehalis municipal water
supply.

Phase I investigation work for preparation of a site-wide remedial
investigation/feasibility study. Within the HRIA study area, collected surface water
from Berwick Creek and groundwater from existing monitoring and private water
supply wells. Outside of HRIA study area, installed and sampled temporary borings
and permanent monitoring wells, collected stream-bed soil samples from Berwick
Creek, collected soil gas samples on Breen property.
To date, eliminated some potential sources areas on
the Breen property from consideration. Added to
understanding of distribution of PCE in soil and
groundwater. Found greater downgradient extent of
PCE in groundwater than previous investigations.

Notes:
1. PCE concentrations for some wells were ignored
d ue to the sample being located in a transition
zone between the shallow and deep zones of
the shallow aquifer. It is presumed that these
I ocations underestimate true maximum
co ncentrations in the deep zone, especially
do wngradient of the United Rentals Building.
2. Contours are based on maximum groundwater
co ncentrations and do not represent a single

MEMORANDUM
SUBJECT: Revision 4 - Hamilton/Labree Superfund Site Study Limitations Analysis
Project Name: EPA R-10 AES - Hamilton/Labree Negotiation Support
FROM: Marcia Knadle, Hydrogeologist
TO:
Tamara Langton, Project Manager
1.0 INTRODUCTION
EPA Region 10, with the support of the Parametrix Team (Contractor), is currently developing a
Remedial Investigation/Feasibility Study (RI/FS) for the Hamilton/Labree Roads Groundwater
Contamination Site in Chehalis, Washington (Site). The purpose of this technical memorandum is to
present an analysis of the limitations of the investigation data collected to date and to identify additional
data and activities needed to characterize the Site prior to selection of a remedy. A primary focus of
further investigation will be to better understand the interaction of the identified groundwater plumes to
assist in development of a refined conceptual site model (CSM) for the Site.
2.0 SITE DESCRIPTION
The Site is located near the intersection of North Hamilton Road and Labree Road, west of Interstate 5 (I-
5), about 2 miles south of the City of Chehalis, Washington. The Site includes two areas where releases
of hazardous wastes are known to have occurred: Operable Unit 1, which is hereafter referred to as the
Hamilton Road Impact Area (HRIA), and the S.C. Breen Construction Company (Breen) Property. The
Site also contains an area where a release is likely to have occurred called, for purposes of the Remedial
Investigation (RI) Report, the Thurman Berwick Creek Area (Attachment 1). Contaminated groundwater
plumes originate from these areas extending downgradient and west of Labree Road. The Breen Property,
the Thurman Berwick Creek Area, and downgradient areas outside of the HRIA compose Operable Unit
2.
The primary contaminant of potential concern (COPC) at the Site is tetrachloroethylene (PCE). Minor
amounts of reductive dechlorination products (trichloroethylene [TCE], cis-l,2-dichloroethylene [DCE]
and vinyl chloride) also occur mostly near source areas, but the groundwater is too oxygenated for
biodegradation to be a major natural attenuation process. Other COPCs across the Site are
tetrahydrofuran and methylene chloride. Total Petroleum Hydrocarbons (TPH) is also being considered
as a presumptive COPC until proven otherwise.

3.0 STUDY LIMITATIONS
The data used to prepare the RI Report represents a compilation of numerous published documents and
data not previously presented in reports, which were generated by a variety of consultants and the EPA
between 1993 and 2007. Investigations were conducted on behalf of the EPA, the Department of Ecology
(Ecology) and the Breen Company over the years. The table in Attachment 2 provides a summary of
investigations conducted to date at the Site. The challenges in compiling the RI Report using the various
data sources included:
• The varying purposes of the different phases of investigations
• Varying investigation methods utilized over the years
• Improvements in various technologies (i.e., soil sample collection methods)
• Loss of data
• Transcription errors
• Unsurveyed exploration locations
• Changes in personnel working on the project over time
• Differing opinions by the various consultants and agencies working on the project
• The complexity of this site
It is therefore acknowledged that there may be inconsistencies in the RI Report at times, and there are
numerous data gaps remaining for the RI.
The limitations of the remedial investigations conducted to date across the Site range from data gaps
affecting our ability to delineate confidently the magnitude and extent of PCE contamination to gaps in
our fundamental understanding of the physical controls on how PCE migrates in groundwater which
could significantly alter the CSM. These "gaps" include:
• Understanding of the nature, age, and location of all sources, and plume dynamics.
• Explaining the large spatial differences in source-to-plume contaminant mass-transfer processes
both vertically and horizontally, as evidenced by an apparent transport "bottleneck" downgradient
of the HRIA (see Section 6 for further discussion of the "bottleneck"). The graph in
Attachment 3 depicts concentrations versus distance from the HRIA and illustrates the
"bottleneck."
• Identifying the location and fate of the downgradient edge of the plume, in particular, whether it
discharges to surface water (Dillenbaugh Creek).
Additional characterization can resolve some of these gaps such as site-wide hydraulic characteristics and
the vertical distribution of PCE in the plume downgradient of Labree Road, while others will require
more sophisticated analysis such as a stable isotope study or analyzing for tentatively identified
compounds (TICs) to distinguish between the PCE from the HRIA, the Breen Property, and the Thurman
Berwick Creek area. However, resolution of other gaps could require information that may never be
available (e.g., historical information regarding activities in potential source areas).
This "data gaps analysis" first looks at several site-wide data needs and suggests activities to address
these needs. It then discusses the HRIA followed by the Breen Property, the area between the HRIA and
-------
3
the Thurman Berwick Creek Area (the "bottleneck"), the Thurman Berwick Creek area, and finally the
downgradient area west of Labree Road.
4.0 SITE-WIDE
4.1 Potential Sources of Contamination/Identified Data Gaps
This section presents the identified Site-wide data gaps based on historical data review and analysis and
recommended additional activities to fill those gaps.
4.1.1 Groun d wa ter Plum e
The estimated groundwater plume configuration in the area of the HRIA, Breen Property, and Thurman
Berwick Creek area, and site-wide are shown in Attachments 4 and 5, and RI Report Figures 4-6 and 4-
7, respectively. The RI Report figures for the PCE plume in the source areas (HRIA, Breen Property, and
Thurman Berwick Creek Area) show worst-case scenarios for both the upper zone (5-25 feet deep) and
the lower zone (25-45 feet deep) of the shallow aquifer. These hand-drawn isoconcentration contours are
biased to show as much contaminant mass migrating from the HRIA to the other sources as can
reasonably be inferred. As such, the contours ignore some isolated low concentration data points.
In contrast, the upper and lower zone plume maps for the shallow aquifer shown in Attachments 4 and 5
use the same data but show contours produced by a natural-neighbor contouring program. These maps
suggests two isolated sources of PCE contaminate the upper zone while in the lower zone less than 500
micrograms per liter (j^ig/L) of PCE from the HRIA reaches the Breen Property, and little to no PCE from
the HRIA reaches the Thurman Berwick Creek area. Because contouring programs do not take
groundwater flow into account and use all active data points, they do not connect areas of high
concentration along flow lines that have been connected on the hand-drawn figures. EPA considers the
hand-drawn figures to be more representative of true site conditions, but the computer contoured figures
help highlight areas where additional groundwater data are needed to confirm the extent of PCE migration
from the HRIA and to identify any other source(s) of lower zone PCE in the area between the former
United Rentals Building and the Thurman Berwick Creek area.
As shown on the hand-drawn contours (RI Report Figures 4-6 and 4-7), PCE in groundwater at
concentrations greater than 1,000 |a,g/L originating from the HRIA does not appear to have reached the
Thurman Berwick Creek area. Assuming the hand-contoured lower zone figure is correct, concentrations
of PCE slightly greater than 1,000 (ig/L may have reached the suspected Breen Property source areas
along Labree Road. Little or no PCE contamination from the HRIA has reached either the Breen Property
or Thurman Berwick Creek Area sources in the upper zone. PCE at concentrations at or less than 1,000
|jg/L has presumably commingled with the PCE plume originating from the Breen property and an
apparent PCE plume originating from or just upgradient of the Thurman Berwick Creek area.
Currently, the extent of the PCE groundwater plume downgradient of the Breen Property and the
Thurman Berwick Creek area west of Labree Road is unknown, but a narrow plume of about 1,000 (ig/L
appears to extend at least 3,000 feet downgradient of Labree Road, based on concentrations in MW-25
and boring RS-20, the most downgradient data points in the plume. Because the end of the plume has
never been located, it is unknown whether the plume is stable or expanding, or whether it (or some
portion of it) discharges to surface water (Dillenbaugh Creek). Without this information, it's impossible
to produce a robust ecological risk assessment, to be confident that no additional private wells may be
impacted, or to evaluate whether natural attenuation processes can contain the plume. In addition, the
plume edges in the downgradient area west of Labree Road have not been adequately established,
particularly on the northeast edge parallel to 1-5.

4.1.2 Un certain ty R el a ted To Groun d wa ter Plum e
Three-dimensional geostatistical modeling was completed by CDM using Environmental Visualization
Software (EVS) (CDM 2009). This modeling was used, in part, to help identify possible areas of the site
where available groundwater data was insufficient to adequately characterize the area. To assist in
assessing site-wide data gaps, uncertainty plots were created using EVS. Uncertainty plots generated
using EVS are included as Attachment 6.
Uncertainty tends to be highest where the model predicts a high concentration, but there are no samples in
the area to provide any confidence. On these plots, areas with green, yellow or red coloration have the
highest uncertainty and are areas where additional sampling is recommended. As shown in these plots,
areas with the highest uncertainty include:
• The area west of the Thurman Berwick Creek Area, east of PW-21, and south of RS-49
• The downgradient area west and northwest of the Breen Property and Thurman Berwick Creek
Area, including the area around and downgradient of MW-25
Other areas of the site where high uncertainty exists were also identified using the completed EVS model
and through non-EVS related evaluation, including whether high concentrations of PCE actually exist in
the southeastern corner of the Breen Property as indicated by the EVS model.
4.2 Other Site-Wide Data Gaps
This section discusses other data gaps that are common to all areas of the Site.
4.2.1 Hydraulic Conductivity and Other Aquifer Parameters
The hydraulic conductivity for the aquifer at the Site requires further evaluation, especially in
downgradient areas. Aquifer testing was conducted and hydraulic conductivity values were generated for
the HRIA and the Breen Property (URS 2004, Farallon 2004). However, there are no hydraulic
conductivity values for the areas west of the United Rentals facility and west of Labree Road. For
assessing and modeling plume migration in groundwater, a site-wide understanding of hydraulic
conductivity is necessary. To evaluate whether the hydraulic conductivity measurements from the
sources of contamination are applicable to the entire site, hydraulic conductivity should be determined for
the aquifer in the downgradient areas, including the "bottleneck" area between the HRIA and the
Thurman Berwick Creek Area. Existing logs do not indicate any significant geologic discontinuity in the
area downgradient of United Rentals to explain the transfer "bottleneck"; however, there are few well
logs for that area.
In addition, other aquifer characteristics, such as porosity (total/effective), vertical/horizontal gradients
and anisotropy should be determined for the downgradient areas to assist in plume modeling and
migration assessment.
4.2.2 Vertical Distrib u tion of PCE in Groun dwa ter
The vertical distribution of PCE in groundwater requires further assessment. Information on the vertical
distribution of groundwater contamination at the HRIA, Breen Property, and the Thurman Berwick Creek
Area is available, and separate cross-sections showing the distribution have been prepared. Three-
dimensional geostatistical modeling (CDM 2009) was completed for the Site, but showed several areas
where data gaps existed in vertical distribution of PCE including an area located between the HRIA and
-------
5
Thurman Berwick Creek Area. In addition, information on the vertical distribution of PCE in the area
downgradient and west of Labree Road is limited. The collection of additional groundwater samples at
various depth intervals within the shallow aquifer is required. This information is useful in assessing
groundwater/surface water interaction in downgradient areas to determine the volume of PCE
contaminated water that is potentially discharging to the surface water of Berwick Creek and Dillenbaugh
Creek versus the volume that is potentially migrating past. The vertical distribution of PCE is also
necessary for interpreting the interaction of contaminated groundwater for the various sources in the
shallow aquifer and identifying additional sources at the Site.
The vertical distribution is also useful in assessing potential vapor intrusion since the volatile organic
compound (VOC) concentration at the groundwater water table is normally directly related to the
potential VOC concentrations in indoor or ambient air.
4.2.3 Groun d wa ter Plum e Modeling
Groundwater contaminant fate and transport modeling efforts have been completed for the Site by
Farallon (2004) and URS (2004) using Biochlor, and groundwater flow and contaminant fate and
transport modeling was performed by CDM (2007) using MODFLOW-96 and MT3DMS. However, very
different hydrologic characteristics were used for different models, so it is difficult to compare or use the
fate and transport results. Moreover, none of the existing models take the transport "bottleneck" into
consideration, which seriously limits their usefulness. Groundwater modeling should be completed
following collection of new chemical and physical data discussed elsewhere in this technical
memorandum and determination of site-wide aquifer parameters including hydraulic conductivity and
porosity, assuming that these data collection efforts improve the fundamental understanding of the site. A
three-dimensional model would be most appropriate because of the spatial variability in vertical
distribution of PCE in groundwater. Fate and transport modeling should be done using a model that can
at least generally account for contaminant matrix diffusion and back diffusion processes (e.g., RemChlor).
As stated in Section 4.1.2, three-dimensional geostatistical modeling using EVS was completed by CDM
in 2009. This modeling effort should also be updated using the newly collected chemical data for soil and
groundwater discussed elsewhere in this technical memorandum to provide a better depiction of the
current groundwater plume configuration.
4.2.4 Evaluation of Production Well Influences on Plume
Since completion of the City water main extension in November 2002, production wells local to the
HRIA and Thurman Berwick Creek Area have not been influencing the groundwater flow regime.
However, numerous water supply wells exist within a 4-mile radius of these sites and may have some
influence on gradient conditions recorded at the site during these historical investigations. This influence
needs further characterization through analytical and/or numerical modeling efforts to enhance
understanding of past and present pumping well influence to plume migration. This information can also
be used to determine if additional institutional controls may be needed to protect existing potable water
supplies.
4.2.5 Evalua tion of Deep Aquifer
The deep aquifer has never been specifically characterized and no monitoring wells have been screened
within it. A few private wells are completed in the deep aquifer across the Site. However, only two of the
deep aquifer private wells (PW-1 and PW-8) are located in areas of significant shallow aquifer
contamination and these two wells are situated within and near the Breen Property. No deep aquifer wells
are located within the HRIA. The data is too limited to conclude that the deep aquifer has not been
-------
6
impacted. Further, the data from the two deep wells is relatively old (last sampled in 2003). No recent
data has been collected from the deep aquifer to determine if PCE may have migrated below the aquitard.
4.2.6 Stable I sot op e Study
A stable isotope study, including analysis of TICs, should be conducted to attempt to distinguish between
the PCE from the HRIA, the Breen Property, and the Thurman Berwick Creek Area. A similar study was
successfully completed at the nearby Palermo Well Field Superfund Site in Tumwater, Washington
(Vlassopoulos 2006) to determine the party responsible for contamination identified in the City of
Tumwater drinking water source wells. Presuming that PCE migrating from the different sources has
sufficiently different isotopic or TIC characteristics, the study should be completed to:
• Determine whether the PCE at the Thurman Berwick Creek area is related to the HRIA release or
associated with Breen Property contamination
• Determine the extent of PCE related to the HRIA source in the deeper portion of the plume
downgradient of Labree Road
• Determine the source of PCE detected in private well PW-21
4.2.7 Vapor Intrusion Sampling
Sub-slab, indoor, and ambient air sampling to assess vapor intrusion was conducted at the Site in
November 2007. Limited potential risk related to vapor intrusion was identified. The results of the
sampling are described in the Baseline Risk Assessment Report (CDM 2011). The risk estimates for air
and the corresponding source evaluation for COPCs in indoor air for the Baseline Risk Assessment are
based on one round of sampling in November 2007.
Several significant uncertainties, however, lower confidence in this vapor intrusion risk evaluation.
• Data collected (groundwater, soil, air, etc.) are relatively old and may not reflect current
conditions; thus, the evaluation may not be relevant for 2011.
• Air data were collected only once over a two day period. Air data may vary significantly over
time and by season, and it is not possible to determine how available data reflect air
concentrations over time. Possible exposure concentrations could be significantly under- or over-
estimated.
• Outdoor air data suggest that this medium may be a major source to indoor air. A large
contribution from outdoor air could make a smaller contribution from the subsurface. It was
difficult to determine how shallow groundwater data reflect VOC concentrations at the top of the
water table. Such data best characterize the source of VOCs in soil gas, and would be best for
estimating ratios between indoor air and groundwater. Ratios could be either under- or over-
estimated.
Air sampling is recommended following completion of remedial action at the HRIA to assess changing
conditions resulting from the action.
4.3 Activities to Fill Gaps
A summary of the activities recommended to fill the Site-wide gaps identified above include:
-------
7
• Conducting aquifer testing in the area downgradient and west of Labree Road and downgradient
of the United Rentals facility. Aquifer testing west of Labree Road would be completed using
existing well MW-25 and new monitoring wells. Testing would be conducted on multiple wells
to provide adequate spatial distribution of hydraulic conductivity in the downgradient area.
• Evaluating horizontal and vertical hydraulic gradients Site-wide in and between the upper and
lower zones of the shallow aquifer and assessing seasonal gradient shifts in direction by
collecting comprehensive gradient data at least quarterly for one year.
• Evaluating depth-discrete variations in hydraulic conductivities and preferential pathways
associated with relatively higher-conductivity stratigraphic layers within the shallow aquifer by
conducting aquifer testing within temporary boreholes and completed wells screened at discrete
depths within the aquifer and include findings in numeric and 3D EVS modeling.
• Collecting soil core samples for analysis of porosity, density, and grain size analysis. Collect
core samples from up to two borings and at several depth intervals in the area downgradient and
west of Labree Road.
• Conducting additional assessment and mapping of the site-wide vertical distribution of PCE in
groundwater. In particular, contaminant characterization is needed for the upper zone of the
shallow aquifer between the transport "bottleneck" and the Thurman Berwick Creek area; the
lower zone of the shallow aquifer between the United Rentals building and the transport
"bottleneck," and centerline- and cross-plume transects from Labree Road to the end of the
plume.
• Evaluating the relative contribution of the HRIA, Breen Property and/or Thurman Berwick Creek
Area contaminant sources on contaminant mass loading to the Site-wide contaminant plume by
evaluating mass discharge of contaminants from proposed transects.
• Installing shallow piezometers within the stream bed along Berwick and Dillenbaugh Creeks to
measure head differences between the surface water of the creek and the groundwater within the
bed/or slightly below the bed of the creek in order to determine if and where groundwater may be
discharging to the creeks.
• Sounding the depth of private wells with no logs that are located within the plume. A better
understanding of the depth intervals represented by samples from private wells would be helpful
for mapping or modeling the data.
• Installing monitoring wells screened in the deep aquifer within the HRIA, Breen Property and
Thurman Berwick Creek Areas to determine if it has been impacted by migration of
contamination from the shallow aquifer. These wells would need to be carefully installed using
best practices to prevent contamination from the shallow aquifer from migrating to the deep
aquifer during and after well construction.
• Updating site-wide EVS modeling using newly acquired Site chemical and physical data
discussed in other sections of this technical memorandum. Update three-dimensional modeling
using the newly collected aquifer parameters.
• Conducting a stable isotope study, including analysis of TICs, to distinguish between PCE from
the HRIA, the Breen Property, and the Thurman Berwick Creek area.
-------
8
• Conducting additional indoor and ambient air sampling following completion of remedial action
at the HRIA.
In addition to the above activities, sampling and analysis of the following constituents needs to take place
across the Site:
• Limited sampling and analysis for petroleum hydrocarbons has been conducted at the Site.
During completion of the Baseline Risk Assessment, petroleum hydrocarbons were identified as
requiring further evaluation. Additional sampling and analysis for petroleum hydrocarbons in
soil and groundwater is required at the Site.
• No analyses have ever been conducted for metals in groundwater at the Site. Future site-wide
groundwater sampling activities should include this analysis.
• Limited sampling of semi-volatile organic compounds (SVOCs) and pesticides has been
conducted at the Site. These constituents should be sampled and analyzed especially at the source
areas.
5.0 HAMILTON ROAD IMPACT AREA (HRIA)
This section presents the data gaps identified for the HRIA specifically based on historical data review
and analysis, and recommended additional activities to fill those gaps.
5.1 Potential Sources of Contamination/Identified Data Gaps
Soil and groundwater in the HRIA appear to be adequately characterized for the purpose of determining
nature and extent of contamination in these media for purposes of the remedial investigation and selection
of a remedial action. However, the activities identified below should be conducted at the HRIA prior to
or during remedial design.
5.1.1 Soils
Based on review of historical data, soil samples collected for VOC analysis did not appear to have been
collected and preserved using the protocols under EPA Method 5 03 5A with the exception of the sampling
done in the HRIA in 2003 for the Engineering Evaluation/Cost Analysis (EE/CA) (URS 2004). The
primary goal of this VOC collection and preservation technique is to minimize the direct volatilization of
contaminants in soil to the atmosphere. Although there is a possibility that VOC results from earlier
studies are biased low, no additional soil sampling is recommended at this time as the nature and extent of
contamination appear to have been adequately characterized in this area during the EE/CA.
5.1.2 Groun d wa ter
The MW-600 series wells installed in 2003 for the EE/CA (URS 2004) are fully screened through the
shallow aquifer and were supposed to be decommissioned if not used soon as groundwater extraction
wells. Depth-specific sampling conducted in 2003 revealed strong vertical PCE gradients within the
screened interval in many of these wells, including one well (MW-602) that had concentrations greater
than the PCE solubility limit in the upper zone of the shallow aquifer, indicating the presence of DNAPL.
These wells have since sat unused, which may have resulted in increased vertical migration of
contaminants within the shallow aquifer.
-------
9
5.1.3 Surface Water
No surface water sampling has been completed in Berwick Creek in the northern portion of the HRIA
between MW-R4 and MW-33 (see Attachment 7, Figure 2-1). High PCE concentrations have been
detected in nearby MW-R3 (Northwestern Hot Spot) and MW-33. Currently it is unknown if
contaminated groundwater related to these high PCE concentration areas is discharging to surface water
or vice versa in this stretch of Berwick Creek.
5.1.4 Creek Bed Sedim en t/Soil
The quality of soil/sediment in the stretch of Berwick Creek between MW-R4 and MW-33 has not been
evaluated. Additional characterization of soil/sediment and water quality in this area is required.
5.2 Activities to Fill Gaps
In addition to the activities suggested under the Site-wide section of this report, the following activities
are recommended for the HRIA to fill the above gaps:
• Conduct pre-remedial design soil sampling to validate what VOCs and other contaminants (such
as petroleum hydrocarbons which were identified during completion of the Baseline Risk
Assessment as requiring further evaluation) are present and at what concentration. The need for
this investigation would be assessed once a remedial alternative is selected and prior to remedial
design.
• Collect depth-specific groundwater samples from the MW-600 series wells. If results indicate
significant downward migration of contamination, these wells should be abandoned.
• Collect surface water samples at 6 to 8 locations in Berwick Creek, in the section of creek between
roughly MW-R4 and MW-33. No surface water sampling appears to have been collected within
this length of Berwick Creek.
• Collect soil/sediment samples in the section of Berwick Creek between roughly MW-R4 and MW-
33. Install four to six borings within Berwick Creek and collect two soil/sediment samples from
each boring. Samples need to be collected from the silt layer comprising the creek bed, as opposed
to newly deposited sediments.
6.0 "BOTTLENECK"
6.1 Identified Data Gaps
A north-south zone located between the HRIA and the Thurman Berwick Creek Area and characterized
by a dramatic reduction in PCE groundwater contamination has been identified and confirmed by EVS
modeling. This zone is located east of where North Hamilton Road crosses Berwick Creek, beginning in
the area between the former United Rentals building and continuing west through the line of wells
containing MW-22, MW-23 and MW-24 (see Attachment 7). It appears to act as a PCE transport
"bottleneck," preventing significant amounts of PCE from reaching the Breen Property and the Thurman
Berwick Creek Area. Within the "bottleneck," the upper zone (upper 25 feet) of the shallow aquifer has
little to no PCE contamination, so that the plume is confined to the lower zone (approximately 25 to 50
feet below ground surface [bgs]). Even there, the concentrations are much lower than modeling predicts.
Additional evaluation should be conducted to assess this transport "bottleneck," including better
-------
10
definition of the north and south ends. Conceptual site plume centerline and transect cross-sections
depicting this area of low PCE concentration in groundwater are presented in Attachment 8.
There is an area upgradient of the "bottleneck" and just west of the HRIA where little groundwater and
soil data is available. Only a couple of sampling points (B6 and B7) have been installed between
monitoring wells MW-3 and MW-22/MW-23. Groundwater data is limited to two sampling intervals per
location and does not include data for the shallowest (0 to 15 bgs) or deepest portions (greater than 35 feet
bgs) of the shallow aquifer. Additional data is necessary in this area to fill the data gaps related to the
upper and lower zone contamination in the shallow aquifer and to provide additional data for evaluating
and mapping out the extent of the "bottleneck." This information may also help confirm that the apparent
southern lobe of the PCE plume in the lower zone is from the HRIA.
6.2 Activities to Fill Gaps
In addition to the activities suggested under the Site-wide section of this report, the following activities
are recommended for the "bottleneck" area:
• Complete one to two north-south boring transects between MW-3 and MW-22/23 to assess
contaminant mass discharge at the outlet of the HRIA source area and the inlet of the interface
with the Breen/Thurman Berwick Creek source(s). The boring transect(s) should consist of three
to four borings and extend north to the building south of the livestock auction building on the
Breen Property and south to the area east of RS-24. Groundwater samples should be collected
from four different intervals in each boring: at approximately 5 feet bgs, from 15 to 25 feet bgs,
from 30 to 40 feet bgs, and from 40 feet to the base of the aquifer, typically at 50 feet bgs. This
sampling strategy will provide two samples from the shallow zone and two from the lower zone
for characterization since the apparent bottom of the "clean" zone in the "bottleneck" ranges from
20 to 30 feet.
• Install at least two borings to characterize and define the north and south ends of the "bottleneck"
and two additional borings between MW-24 and RS-24. Groundwater sampling would be
completed at the same intervals as discussed in the previous bullet.
• Install two to three centerline borings in both the northern and southern plume lobes as needed to
fill in between north-south transects. These should extend as far as the Breen wash-down pad for
the northern plume lobe and to Labree Road for the southern plume lobe.
• Install a transect extending east and west from the HRIA source area containing DNAPL
(Southeastern Hot Spot) to the Thurman Berwick Creek Area. Collect lithologic information and
aquifer parameters as discussed in the Site-wide section. Groundwater sampling would be
completed at the same intervals as discussed for the two north-south transects between MW-3 and
MW-22/23. Use information from this transect to prepare a cross-section identifying conditions
from the HRIA, through the "bottleneck", and to the Thurman Berwick Creek Area.
An alternative investigative methodology to consider for the investigations described above is the use of
down-hole subsurface profile technologies. Specifically, the use of:
• Hydraulic Profiling Tool (HPT) to obtain soil hydraulic property profiles and measure static
water levels. The HPT uses a sensitive down-hole transducer to measure the pressure response of
the soil to injection of water.
-------
11
• Membrane Interface Probe (MIP) to obtain real time information on where PCE is and is not
present at depth, the relative concentrations at depth, and where the contaminant occurs in
relationship to the lithology.
• Electrical Conductivity (EC) probe to obtain the lithic composition, as well as soil hydraulic
properties.
These down-hole tools are advanced using Direct Push Technology (DPT) methods. While past attempts
to utilize DPT at the Site have been met with less than optimal results, current equipment may have better
success. Besides being able to obtain continuous data, economically speaking, the number of borings that
can be extended using DPT is typically much greater than traditional drilling methods. The data gained
would generate more accurate cross sections of the Site lithology and contaminant distribution than would
traditional drilling methods. Further, if these screening technologies are utilized, the information gained
would be used to minimize subsequent drilling efforts as the number and location of subsequent borings
and monitoring wells would be reduced and situated in such a manner that will provide the most useful
information.
7.0 BREEN PROPERTY
This section presents the data gaps identified for the Breen property based on historical data review and
analysis, and activities to fill these gaps.
7.1 Potential Sources of Contamination/Identified Data Gaps
In September 1999, approximately 70 5 5-gallon drums and other containers, and 600 tons of PCE and
petroleum contaminated soil were removed from beneath the southeast end of Building B on the Breen
Property (Attachment 9). Samples collected from the final excavation were either non-detect or
contained contaminants below Ecology's Model Toxics Control Act (MTCA) Method A and/or Method B
cleanup levels (GeoEngineers 2001) applicable at that time.
Since that time, no other sources of contamination to groundwater have been found; however, based on
the interpretation of historical and more recently collected (July 2007) groundwater analytical data, there
appears to be several additional sources on the Breen Property that may be contributing to groundwater
contamination. The exact locations have not been identified but may include the following:
• In the area of the wash-down pad
• In the area between Building B and Building C including:
> The area upgradient of monitoring well MW-27
> The Torpedo Tube area
• In the area surrounding Building B
These areas are shown in Attachment 9.
Wash-Down Pad and Surrounding Area
The wash-down pad, located near the southwest corner of the Breen Property, has been the subject of
several investigations (GeoEngineers 2001, Farallon 2003). Based on historical accounts, waste from the
-------
12
steam cleaning operation conducted at the wash-down pad was collected in an approximately 5-foot deep
pit excavated adjacent to the pad, which has not been located to date. Up to 2,100 (ig/L of PCE has been
detected in MW-8 (screened in the lower zone of the shallow aquifer) immediately adjacent to the
downgradient side of the wash-down pad. Even more suggestive of an active source separate from the
HRIA, 2,400 (ig/L PCE was found in groundwater sampled at 24 feet bgs in boring RS-7 and 1,500 (ig/L
in groundwater sampled at about 20 feet bgs in boring SG2-15, both located about 40 feet east of the
wash-down pad. These concentrations are far higher than upper zone concentrations found in the
"bottleneck" area 200 feet to the east, or in MW-29 (a shallow well located just 50 feet to the east),
strongly suggesting a local source just upgradient of the wash-down pad.
Between Building B and Building C
Area Upgradient of MW-27:
The source of groundwater contamination in MW-27 is still not known. In 2003, PCE was detected in
MW-27 at a maximum concentration of 1,500 (ig/L. This well is screened in the lower zone of the
shallow aquifer from 27 to 42 feet bgs. PCE was detected in RS-1, located upgradient and approximately
400 feet east of MW-27, at 260 (ig/L at a depth of 30 feet bgs and at 84 (ig/L at a depth of 46 feet bgs.
Since that time, no sampling has been conducted immediately upgradient of MW-27 or in the area
between MW-27 and RS-1. A 1969 aerial photograph of the Breen property shows a possible trench
containing debris or drums roughly 100 feet east and upgradient of MW-27. The area containing this
trench does not appear to have been part of the 2000 GeoPotential investigation, or a 1996 GeoRecon
geophysical investigation conducted at the site.
A metal cover was observed in the area of MW-27 during the July 2007 sampling event. A second metal
cover/plate was observed just north/northwest of the wash-down pad and south/southeast of Building C.
What these objects are covering is unknown and will require further evaluation to determine if it could be
associated with a potential source for groundwater contamination.
Building B
As stated above, a cleanup was conducted in 1999 under Building B to remove drums identified by a
ground penetrating radar survey (GeoEngineers 2001). PCE was detected in air samples collected in
November 2007 in and under the building. This may suggest a source of contamination to groundwater
under or around Building B.
Other Potential Source Areas
Other potential sources may also exist at the Breen Property including a possible area upgradient of RS-6.
There are several other areas of the site with PCE concentrations in groundwater exceeding 200 (ig/L.
This includes an area located south of the Livestock Auction Building in the southeast corner of the Breen
Property (see Attachment 9). Although some soil and groundwater investigations were completed in the
area of geophysical anomalies by Farallon (2003), no source for this contamination was identified. EVS
modeling places significant amounts (>1,000 (ig/L) of PCE in groundwater beneath the southeast end of
the Livestock Auction Building, extending southeast to merge with contamination from the HRIA. Since
no contamination source was found in this reach of Berwick Creek, the area of groundwater directly to the
north was assumed to be mostly clean and has been mapped as such on the RI plume maps (RI Report
Figures 4-6 and 4-7). In light of the contamination in the upper and lower zones of the shallow aquifer
just downgradient of the building south of the Livestock Auction Building, as well as the geostatistical
modeling results, this assumption needs to be tested.
Potentially Naturally Occurring Biodegradation
-------
13
Natural biodegradation of PCE is apparent around Building B, particularly at the downgradient side of the
building, based on DCE and vinyl chloride concentrations being higher than PCE concentrations.
Understanding the reason for this may be useful in evaluating: 1) processes that may be limiting the
migration of PCE originating from this area, 2) evaluating remedial options of the site, and 3) the
presence of other COPCs (i.e., petroleum hydrocarbons) and the role they have in biodegrading PCE.
Soil Sampling
Based on review of historical data, soil samples collected for VOC analysis did not appear to have been
collected and preserved using the protocols under EPA Method 5035A. The primary goal of this VOC
collection and preservation technique is to minimize the direct volatilization of contaminants in soil to the
atmosphere. Since EPA Method 5035A does not appear to have been utilized during soil sample
collection, there is a strong possibility that VOC analytical results have been biased low, especially for
samples collected from the gravelly materials that comprise the shallow aquifer.
7.2 Activities to Fill Gaps
In addition to the activities suggested under the Site-wide section of this report, the following activities
are recommended for the Breen Property to fill the above gaps:
• Conduct a passive soil gas survey that covers most of the area generally between the Livestock
Auction Building and Labree Road, and between Hamilton Road and Building A as a first level
screening effort to evaluate potential contaminant source areas. Gore® or Beacon are examples of
two passive soil gas module types that can be utilized in this type of survey.
• Conduct a geophysical investigation in areas not previously investigated (such as the 1969 trench
area, area east of MW-27, the metal cover near MW-27, the metal cover north/northwest of the
wash-down pad, the area surrounding the wash-down pad, and in areas identified by the passive
soil gas survey) to attempt to locate potential sources.
• Conduct a subsurface investigation in the following areas and additional areas identified by the
geophysical and soil gas survey investigations:
> Around the wash-down pad and upgradient of the wash-down pad (area between the wash-
down pad and RS-1)
> Between Building B and Building C, and between RS-1 and MW-27, including the area of
the 1969 trench
> Around and upgradient of the Torpedo Tube
> Surrounding Building B
> Other areas identified by the passive soil gas survey and/or geophysical investigation
described above, and areas containing geophysical anomalies that were not previously
evaluated
• Install two to three additional monitoring wells in areas identified by the subsurface investigation.
• Install additional monitoring wells in the southeastern and central portions of the property to
evaluate a potential northern migration pathway from the HRIA.
-------
14
Soils analyses would include VOCs (with samples properly preserved per EPA Method 5035A) and
petroleum hydrocarbons.
Since comprehensive groundwater monitoring has not been completed at the site since 2003, a current
"snapshot" of groundwater conditions at the Breen Property is unknown. Additional area-wide
groundwater sampling is necessary. Complete a round of groundwater sampling that would include
newly installed wells and existing wells. Analysis would include VOCs, petroleum hydrocarbons, and
metals. In addition, field monitored parameters should be measured and recorded for all wells during
sampling. These parameters include: pH, temperature, oxidation reduction potential, specific
conductivity, dissolved oxygen, turbidity, and ferrous iron (field test kit). Groundwater samples collected
from the upper zone of the shallow aquifer should be analyzed for conventional chemistry parameters
(sulfate/sulfide, nitrate/nitrite, alkalinity, chloride) and for methane, ethane, and ethene (detection limit
0.025 jj./L). Field monitored parameters, general chemistry, and methane/ethene/ethane analyses will be
helpful in evaluating biodegradation processes.
Based on historical information, completing borings and sampling using DPT has been difficult. During
the EE/CA sampling in 2003, the DPT rig was able to complete borings to approximately 30 feet bgs at a
rate of 1 to 1.5 borings per day. The presence of gravelly soils resulted in damage to the DPT tools and
rods and also led to poor sample recovery. A hollow-stem auger was also used for boring/well
installation. The auger rig also experienced problems and a low production rate, but was able to complete
borings/wells to the aquitard at 45 to 55 feet bgs. Because of the apparent boring depth limitation with
the DPT, borings would most likely need to be completed using either hollow-stem auger or sonic drilling
methods. Sonic drilling would likely be the most effective drilling method for completing borings
through the sand and gravel aquifer at the Site. However, boring installation using DPT could be
attempted to determine the applicability of this technology at the Site. Newer, heavier-duty DPT rigs may
be available that could potentially complete boring to a greater depth and in less time than those used
during earlier investigations at the Site.
Approximately 12 to 17 borings should be completed and samples of both soil and groundwater (at
multiple elevations within the aquifer) should be collected. Four soil and four groundwater samples
should be collected per boring. Groundwater samples should be collected at four different intervals in
each boring: a shallow depth (the upper 5 feet of the aquifer), from approximately 15 to 25 feet bgs, from
approximately 30 to 40 feet bgs, and a deep sample from approximately 40 feet bgs to the bottom of the
aquifer (typically around 50 feet bgs). This will provide two samples from the upper zone (< 25 feet bgs)
and two from the lower zone (> 25feet bgs) of the shallow aquifer.
8.0 THURMAN BERWICK CREEK AREA
The Thurman Berwick Creek Area is located immediately south of the Breen Property across North
Hamilton Road. Based on review and analysis of available data, a source to groundwater contamination
may exist in this area. Further discussion of this suspected groundwater source and recommended
activities are discussed in the following sections.
8.1 Potential Sources of Contamination/Identified Data Gaps
PCE concentrations up to 3,740 (ig/L have been detected in groundwater samples collected from private
well PW-9, located in the area. There is no log for this well, so the screened interval is unknown.
However, PCE has been detected in upper zone monitoring wells in this area at concentrations up to 2,700
(ig/L and in lower zone monitoring wells up to 2,000 (ig/L. No source for the high concentrations of PCE
in groundwater detected in the Thurman Berwick Creek Area wells has been identified. These
concentrations are higher than what can be attributed to the HRIA. A possible source for the
-------
15
contamination includes a potential release to Berwick Creek where it turns south from the Breen Property.
Such a release could have migrated through the creek bed and spread throughout the shallow aquifer.
Alternatively, PCE disposal may have occurred in the area between the MW-22/23/24 well line and
Berwick Creek (see Attachment 10).
PCE isoconcentration contour maps completed based on groundwater data for the Site show the 1,000
(ig/L PCE contour from the HRIA in the lower zone of the shallow aquifer bifurcates into a northern and
a southern lobe. The southern lobe does not appear to extend to the Thurman Berwick Creek Area, and
little or no shallow contamination (less than 25 feet deep) from the HRIA extends to wells MW-22 or RS-
19. This would indicate a potential local PCE source upgradient of PW-9 at or upgradient of Berwick
Creek as indicated by high concentrations in upper zone wells MW-31 (2,300 (ig/L) and MW-32 (2,700
(ig/L), as well as in borings RS-31 (1,700 (ig/L at 18 feet) and RS-33 (1,400 (ig/L at 18.5 feet). These
concentrations may be associated with an additional PCE release to Berwick Creek south of the Breen
Property or migration of PCE contamination from another source within the Site. The PCE source for
this groundwater contamination has not been identified.
Creek channel samples CC-1 through CC-9 were collected by Farallon (2004) from Berwick Creek south
of the Breen Property. The samples were collected from the creek bed at approximately 1 foot bgs.
Based on available sampling collection data, it is unclear whether these samples were collected from
sediment accumulations in the creek channel or if the samples were collected into the silt layer that
composes the creek bottom. Based on the creek bed sampling results for the HRIA (URS 2004), the PCE
concentrations were mainly detected within the silt layer. Creek samples CC-1 through CC-9 may not
represent the actual PCE concentrations in the Berwick Creek bed downstream of the Breen Property.
Based on review of historical data, soil samples collected in this area for VOC analysis did not appear to
have been collected and preserved using the protocols under EPA Method 5035A. The primary goal of
this VOC collection and preservation technique is to minimize the direct volatilization of contaminants in
soil to the atmosphere. Since EPA Method 5035A does not appear to have been utilized during soil
sample collection, there is a strong possibility that VOC analytical results have been biased low,
especially for samples collected from the gravelly materials that comprise the shallow aquifer.
8.2 Activities to Fill Gaps
In addition to the activities suggested under the Site-wide section of this report, the following activities
are recommended for the Thurman Berwick Creek Area to fill the above gaps:
• Conduct additional sampling of soil/sediment in Berwick Creek upstream between the North
Hamilton Road bridge and RS-46, and downstream between North Hamilton Road bridge and
Labree Road. To identify potential creek sources for groundwater contamination in this area,
install 6 to 8 borings within Berwick Creek and collect two soil/sediment samples from each
boring (with soil samples properly preserved per EPA Method 5035A). Borings should be
completed into the silt layer comprising the creek bed.
• Complete a north-south boring transect running south from boring B-8 to a line running from
MW-4 to MW-24. Collect soil and groundwater samples in the same manner as discussed for the
"bottleneck" area and Breen Property borings.
-------
16
9.0 DOWNGRADIENT AREA WEST OF LABREE ROAD
This area includes the downgradient portion of the groundwater plume west of the Breen Property and the
Thurman Berwick Creek Area. Identified data gaps and recommended activities to fill these gaps are
discussed in the following sections.
9.1 Extent of Groundwater PCE Contamination/Identified Data Gaps
The extent of the PCE groundwater plume downgradient of the Breen Property and the Thurman Berwick
Creek Area west of Labree Road is unknown (Attachment 1). Currently, there are only two monitoring
wells located in this area, MW-25 and MW-28, although two north-south transects (RS-20/RS-23 and RS-
47/RS-49) of temporary borings with multilevel groundwater samples were installed within the
downgradient plume in 2002 and 2004 (shown on Attachment 1). Borings in the more downgradient
transect were not sampled in the upper zone of the shallow aquifer, so the downgradient extent of the
plume in the upper zone is also unknown.
MW-25 is located approximately 2,000 feet downgradient of Labree Road, and was installed by the
location of temporary boring RS-21. RS-21 was sampled at two different depths in the lower zone of the
shallow aquifer and PCE ranged from 380 to 640 (ig/L. Temporary boring RS-20, located 480 feet
downgradient and sampled at similar depths contained PCE at 450 and 890 (ig/L (highest of a triplicate
sample). RS-20 and RS-21 were installed and sampled in 2002.
MW-25 is screened in the lower zone of the shallow aquifer and has been sampled four times between
August 2002 and July 2007. PCE concentrations in the well have ranged from 760 (ig/L in November
2002 to 600 (ig/L in July 2007. PCE concentrations have been relatively stable between 2002 and 2007
and there is insufficient data to indicate a clear trend over time. It is unclear why MW-25 was located by
RS-21 since RS-20 is another 480 feet downgradient of RS-21and has a similar PCE concentration.
MW-28 is approximately 4,000 feet downgradient of MW-25, and was installed by Dillenbaugh Creek at
the east end of a transect of borings [RS-41/RS-43, all of which had consistently non-detect results (<0.2
(ig/L) at all depths sampled]. MW-28 was sampled twice in 2003 for PCE. The results were non-detect
(<0.2 (ig/L) and 0.35 (ig/L in September and November, respectively. During the July 2007 sampling, the
well could not be sampled due to access issues. As a result, it is unknown how far the downgradient
extent of the plume has advanced past MW-25 and RS-20 and if significant concentrations have reached
MW-28, or if MW-28 is located directly downgradient of MW-25 and RS-20.
9.2 Source of Downgradient PCE Contamination/Identified Data Gaps
The groundwater contamination found at MW-25 appears to be related to the Breen Property and/or the
Thurman Berwick Creek Area, and not significantly associated with the contamination migrating from the
HRIA. This assessment is based on evaluation of sampling data and concentration trends analyses. It is
also based on the apparent constraint in transport from the HRIA imposed by the "bottleneck" located
upgradient of the Breen Property and Thurman Berwick Creek Area.
During completion of the EE/CA (URS 2004), the future fate and transport of PCE at the HRIA was
evaluated using EPA's screening tool Biochlor, Version 2.2. This model was used to estimate the
maximum extent of the PCE plume downgradient of the HRIA in the absence of source control and to
estimate the general effects of implementing source control. Model assumptions included the relative
ages of the two sources (less than 20 years for the HRIA; approximately 40 years for the Breen Property),
and the current understanding of the hydraulic properties of the aquifer which govern how fast the
-------
17
groundwater and any associated contaminants can flow from these sources. Based on the results of the
Biochlor analysis, the following conclusions were made:
• Assuming a 1990 release, the plume emanating from the HRIA would barely have reached MW-
25 by 2002 (observed concentrations in MW-25 were at least 20 times what were predicted by the
model and 100 times the predicted concentrations at RS-20).
• One or more sources located downgradient of the HRIA are contributing to the downgradient
plume west of Labree Road; therefore, the majority of the downgradient portion of the
groundwater plume west of Labree Road most likely originated from the Breen Property.
Evaluation of sampling data and concentration trends analyses appears to confirm the results of the
Biochlor model regarding the extent of the higher concentration portion of the HRIA plume. During the
first three groundwater sampling rounds in 2002/2003, MW-23 and MW-24, located downgradient of the
HRIA, south of the Breen Property and upgradient of the Thurman Berwick Creek Area, showed
generally consistent PCE concentrations. In late 2003, PCE concentrations increased at both wells. In
luly 2007, PCE concentrations had increased further in MW-23, and had restabilized at MW-24. MW-4,
which is located downgradient of MW-23 and MW-24, has also shown an increase in PCE concentrations
with time. The concentration at this well showed a sharp increase in 2001 followed by a steady decrease
in concentration then an increase between late 2003 and 2007. PCE isoconcentration contour maps based
on 2007 groundwater data show that the 1,000 (ig/L PCE contour from the HRIA has not yet reached
Labree Road or even the Thurman Berwick Creek Area.
While the results of the Biochlor model indicated that the HRIA plume extended to MW-25, the model
used a hydraulic gradient that is nearly double that observed over most of the site. Plume extent
calculations using corrected gradients suggest that the plume limit (<5 j^ig/L) should occur at
approximately 500 feet west of Labree Road, and that the majority of the groundwater contamination west
of Labree Road is more likely attributable to the plume originating from the Breen Property and the
Thurman Berwick Creek Area. Only the PCE contamination from the Breen Property appears to have
existed long enough for associated contaminated groundwater to have reached MW-25 and RS-20. This
conclusion is based on current understanding of aquifer hydraulic conductivity, a measure directly related
to how fast groundwater can flow through an aquifer. These measurements have been made only at the
Breen Property and HRIA and have been extrapolated throughout the plume area. This technical
memorandum proposes collecting additional data to confirm that hydraulic conductivity is consistent
throughout the Site.
PCE in private drinking water well PW-21, located along Rice Road, was non-detect (<0.02 j^ig/L) in
1999 and had a detection of 4 (ig/L in 2001. The PCE concentration has subsequently been hovering
slightly above and below 5 (ig/L. Since this well is on the southern edge of the plume, it may record the
arrival of contamination from the HRIA that was pulled south by a pumping production well located
south of the Thurman Berwick Creek Area or it may be associated with another potential source located
upgradient. Additional evaluation is necessary to assess whether the PCE detected in PW-21 is from the
HRIA. If it is, then the assumption that HRIA disposal occurred around 1990 is not supported. It would
suggest that disposal occurred sometime in the 1970s. If this is the case, then the HRIA contribution to
contamination in the lower portion of the plume downgradient of Labree Road may extend considerably
further downgradient than estimated above. However, the proportion attributable to the HRIA would be
limited to the mass flux from the "bottleneck" area, well under half of the PCE mass found in the lower
zone of the shallow aquifer (below 25 feet) and none of the PCE in the upper zone.
As stated previously, a possible source for the contamination identified in the Thurman Berwick Creek
Area includes a potential release to Berwick Creek south of the Breen Property. If a release did occur, it
-------
18
is unknown how far the released contaminant migrated along the creek and where deposition occurred.
The vertical extent of impact to creek bed soil/sediment should be assessed.
9.3 Groundwater/Surface Water Interaction/Identified Data Gaps
The results of sampling in July 2007 showed that PCE in groundwater is potentially being discharged to
surface water in Dillenbaugh Creek near MW-25. It is not understood how this discharge to the creek is
impacting the plume migration (i.e., is the majority of the PCE plume discharging to the creek or
continuing down the valley?). If discharge to Dillenbaugh Creek is controlling the migration of the
plume, it may discharge more directly to the creek where the creek bends to the west between MW-25
and MW-28. There is also a potential for additional groundwater discharge points in Berwick Creek
between Labree Road and the confluence with Dillenbaugh Creek.
9.4 Activities to Fill Gaps
In addition to the activities suggested under the Site-wide section of this report, the following activities
are recommended for the downgradient area west of Labree Road:
• Install two monitoring wells along the plume axis downgradient of the Breen Property between
Labree Road and MW-25. Results of groundwater sampling for transect of soil borings (RS-47,
RS-48, and RS-49) completed by Farallon in 2004 should be used for placement of one well. A
second transect consisting of three soil borings between the RS-47/RS-49 transect and MW-25
should also be installed for placement of the second well.
• Install three to four monitoring wells downgradient of MW-25 along the approximate plume axis.
For determining well placement, install soil borings along three to four transects perpendicular to
the assumed plume axis between Rice Road and Dillenbaugh Creek. Each transect would consist
of three to four borings. Proposed well locations should include between MW-25 and the
suspected "leading edge" of the plume, at or near the "leading edge" of the plume, and between
the "leading edge" and at a downgradient point(s) where the PCE concentration is undetectable.
Groundwater samples would be collected at four different intervals in each boring: a shallow
interval (upper 5 feet of aquifer), from approximately 15 to 25 feet bgs, from approximately 30 to
40 feet bgs, and a deep sample from approximately 40 feet bgs to the bottom of the aquifer
(typically around 50 feet bgs).
• Install two additional borings to the north between RS-47 and 1-5 and collect soil and
groundwater samples to assess the extent of the plume from the Breen Property.
• Install two additional borings in the high-uncertainty area identified in the EVS modeling to the
south of RS-49 and collect soil and groundwater samples to assess the extent of the apparent
plume from the Thurman Berwick Creek Area and to better assess the portion of the plume
upgradient of PW-21.
• Collect surface water samples at 10 to 12 locations in Dillenbaugh and Berwick Creek between
Labree Road and MW-28. This sampling should be conducted in the dry and wet seasons to
assess seasonal effects on concentrations related to changes in groundwater table elevation and
changes in creek flow volume. In addition, collect generally co-located groundwater samples
along the west side of this reach of Dillenbaugh Creek to evaluate the concentrations of PCE in
groundwater potentially being discharged. This could be conducted using borings along the bank
or more innovative approaches, such as phytoscreening (i.e., coring samples from mature trees
along the creek bank) (Sorek 2008).
-------
19
• Depending upon the results of the soil/sediment sampling in the Thurman Berwick Creek Area,
install four to six borings in Berwick Creek between Labree Road and the confluence with
Dillenbaugh Creek and collect two soil/sediment samples from each boring. At least one boring
should be located where Berwick Creek crosses the plume centerline. Samples should be
collected from the silt layer comprising the creek bed, as opposed to the recently deposited
sediment.
As described in Section 6, an alternative investigative methodology to consider as a precursor and to
further focus the investigations described above is the use of down-hole subsurface profile technologies
(HPT, MIP, EC) prior to boring/monitoring well installations.
8.0 SUMMARY OF DATA GAPS AND RECOMMENDED INVESTIGATION
A summary of the identified data gaps and recommended investigations to "fill" these gaps is presented in
the table on the following page.
-------
TECHNICAL MEMORANDUM (CONTINUED)
Summary of Data Gaps and Recommended Investigations
Area
Identified Data Gaps
Recommended Investigations
Site Wide
The hydraulic conductivity for the aquifer at the Site
requires further evaluation, especially in downgradient
areas and in the "bottleneck" area.
Aquifer characteristics, such as porosity (total/effective),
vertical/horizontal gradients and anisotropy should be
determined for the downgradient areas to assist in plume
modeling and migration assessment.
The vertical distribution of PCE in groundwater requires
further assessment. Information on the vertical distribution
of PCE in the area downgradient and west of Labree
Road is limited as is the information for the "bottleneck"
area between the HRIA and the Thurman/Berwick Creek
area. Collection of additional groundwater samples at
various depth intervals within the shallow aquifer is
needed.
A better understanding of the depth intervals represented
by samples from private wells is needed for mapping or
modeling data obtained from these locations.
The deep aquifer has never been specifically
characterized and no monitoring wells have been
screened within it. The data is too limited to conclude that
the deep aquifer has not been impacted.
Site-wide groundwater models should be revised based
collection of new chemical and physical data.
The impact of production wells currently and formerly in
use within a 4-mile radius of the source areas needs to be
evaluated to determine any influences on plume
migration.
A stable isotope study should be conducted to attempt to
distinguish between the PCE from the HRIA, the Breen
Property, and the Thurman Berwick Creek area.
Air sampling is recommended following completion of
remedial action at the HRIA to assess changing
conditions resulting from the action.
Evaluation of petroleum hydrocarbons is needed based
on results from the baseline risk assessment
Metals evaluation is needed.
Conduct aquifer testing in the area downgradient and west of Labree
Road and downgradient of the United Rentals facility. Aquifer testing
west of Labree Road would be completed using existing well MW-25
and the new monitoring wells, discussed earlier in this memo. Testing
would be conducted on multiple wells to provide adequate spatial
distribution of hydraulic conductivity in the downgradient area.
Evaluate horizontal and vertical hydraulic gradients Site-wide in and
between the upper and lower zones of the shallow aquifer and assess
seasonal gradient shifts in direction by collecting comprehensive
gradient data at least quarterly for one year.
Evaluate depth-discrete variations in hydraulic conductivities and
preferential pathways associated with relatively higher-conductivity
stratigraphic layers within the shallow aquifer by conducting aquifer
testing within temporary boreholes and completed wells screened at
discrete depths within the aquifer. Include findings in numeric and 3D
EVS modeling.
Collect soil core samples for analysis of porosity, density, and grain
size analysis. Collect core samples from up to two borings and at
several depth intervals in the area downqradient and west of Labree
Road.
Additional assessment and mapping of the site-wide vertical
distribution of PCE in groundwater.
Evaluate the relative contribution of the HRIA, Breen Property and/or
Thurman Berwick Creek Area contaminant sources on contaminant
mass loading to the Site-wide contaminant plume by evaluating mass
discharge of contaminants from proposed transects.
Install shallow piezometers within the stream bed along Berwick and
Dillenbaugh Creeks to measure head differences between the surface
water of the creek and the groundwater within the bed/or slightly below
the bed of the creek in order to determine if and where groundwater
may be discharging to the creeks.
Sound the depth of private wells with no logs that are located within
the plume.
Install monitoring wells screened in the deep aquifer within the HRIA,
Breen Property and Thurman Berwick Creek Areas to determine if it
has been impacted by migration of contamination from the shallow
aquifer.

Additional soil sampling may be required to validate what
VOCs and other contaminants are present and at what
concentration for the purpose of remedial design.
Surface water requires additional characterization,
particularly in the section of Berwick Creek between MW-
R4 and MW-33 (see Attachment 7, Figure 2-1).
The quality of soil/sediment in this section of Berwick
Creek should also be collected to assess if other potential
PCE sources exist in the creek channel.
The MW-600 series wells installed in 2003 for the EE/CA
are fully screened through the shallow aquifer and were
supposed to be decommissioned if not used as
groundwater extraction wells. They have since sat
unused, which may have resulted in vertical migration of
contaminants within the aquifer.
Pre-remedial design soil sampling to validate what VOCs and other
contaminants (such as petroleum hydrocarbons which were identified
during completion of the baseline risk assessment as requiring further
evaluation) are present and at what concentration. The need for this
investigation would be assessed once a remedial alternative is
selected and prior to remedial design. Soil samples to be collected
using the protocols specified under EPA Method 5035A.
Collect surface water samples at 6 to 8 locations in Berwick Creek, in
the section of creek between roughly MW-R4 and MW-33. No surface
water sampling appears to have been collected within this reach.
Collect soil/sediment samples in the section of Berwick Creek between
roughly MW-R4 and MW-33. Install four to six borings within Berwick
Creek and collect two soil/sediment samples from each boring.
Borings should be completed into the silt layer comprising the creek
bed.
Collect depth-specific groundwater samples from the MW-600 series
wells. If results indicate significant downward migration of
contamination, these wells should be abandoned.

Mass Transfer • A north-south zone located between the HRIA and
Bottleneck Thurman Berwick Creek area was identified during EVS
modeling. This zone is located east of where North
Hamilton Road crosses Berwick Creek and appears to
act as a PCE transport "bottleneck," preventing significant
amounts of PCE from reaching the Breen Property and
the Thurman Berwick Creek area.
• Limited groundwater and soil data is available in an area
upgradient of the "bottleneck" and just west of the HRIA.
Only a couple sampling points (B6 and B7) have been
installed between monitoring well MW-3 and MW-22/MW-
23. Additional data is necessary in this area to fill the
data gaps related to the shallow and deep contamination
in the shallow aquifer and to provide additional data for
evaluating the "bottleneck."
Complete one to two north-south boring transect(s) between MW-3 and
MW-22/23. The boring transect(s) should consist of three to four
borings and extend north to roughly Berwick Creek and south to the
area east of RS-24. Groundwater samples would be collected from four
different intervals in each boring: approximately 5 feet bgs, from 15 to
25 feet bgs, from 30 to 40 feet bgs, and from 40 feet to the base of the
aquifer, typically at 50 feet bgs .
Install two borings to define the north and south ends of the
"bottleneck" and two additional borings between MW-24 and RS-24.
Groundwater sampling would be completed at the same intervals as
discussed in the previous bullet.
Install two to three centerline borings in both the northern and southern
plume lobes as needed to fill in between north-south transects. These
should extend as far as the Breen wash-down pad for the northern
plume lobe and to Labree Road for the southern plume lobe.
Install a transect extending east and west from the HRIA source area
containing DNAPL (Southeastern Hot Spot) to the Thurman Berwick
Creek Area. Collect lithologic information and aquifer parameters as
discussed in the Site-wide section. Collect groundwater samples for the
same intervals noted above. Use information from this transect to
prepare a cross-section identifying conditions from the HRIA, through
the "bottleneck", and to the Thurman Berwick Creek Area.

Breen Property • Only one source (Building B drum cache) has been
identified; however, based on the interpretation of
historical and recently collected groundwater analytical
data there appears to be several additional areas of
contamination still active on the Breen Property that are
contributing to groundwater contamination.
• Comprehensive groundwater monitoring has not been
completed at the site since 2003; a current "snapshot" of
groundwater conditions at the Breen Property is
unknown. Additional area-wide groundwater sampling is
necessary.
• Based on review of historical data, soil samples collected
for VOC analysis did not appears to have been collected,
preserved, and analyzed using the protocols under EPA
Method 5035A.
Conduct a passive soil gas survey that covers most of the area
generally between the Livestock Auction Building and Labree Road,
and between Hamilton Road and Building A as a first level screening
effort to evaluate potential contaminant source areas.
Conduct a geophysical investigation in areas not previously
investigated (such as the 1969 trench area, area east of MW-27, metal
cover near MW-27, metal cover north/northwest of the wash-down pad,
and area surrounding the wash-down pad) to attempt to locate potential
sources.
Conduct a subsurface investigation in the areas identified below.
Advance approximately 12 to 17 borings. Collect four soil and four
groundwater samples from each boring at the intervals discussed in
previous sections. Areas to be investigated include:
o In the area of the wash-down pad and upgradient area (to RS-1)
o In the area between Buildings B and C and between MW-27 and
RS-1
o In the area of the Torpedo Tube
o Surrounding Building B
o Other areas identified by the passive soil gas survey and/or
geophysical investigation described above, and areas containing
geophysical anomalies that were not previously evaluated
Analysis would include VOCs (collected and analyzed per EPA Method
5035A), petroleum hydrocarbons, and metals.
Install two to three additional monitoring wells in areas identified by the
subsurface investigation.
Install monitoring wells in the southeast and central portion of the site
to assess the potential migration pathway from the HRIA.
Complete a round of groundwater sampling that would include newly
installed wells and existing wells. Analysis would include VOCs,
petroleum hydrocarbons, and metals. Groundwater samples collected
from the upper zone would be analyzed for conventional chemistry
parameters (sulfate/sulfide, nitrate/nitrite, alkalinity, chloride), and
methane, ethane, and ethane to assess biodegradation processes.

Downgradient • The extent of the PCE groundwater plume downgradient
Plume West of of the Breen Property and the Thurman Berwick Creek
Labree Road area west of Labree Road is unknown.
• PCE has been detected in PW-21, located on the
southern edge of the plume. It may record the arrival of
contamination from the HRIA that was pulled south by a
pumping production well located south of the Thurman
Berwick Creek area or it may be associated with another
potential source located upgradient. Additional
evaluation is necessary to assess whether the PCE
detected in PW-21 is from the HRIA.
• The results of sampling in July 2007 showed that PCE in
groundwater is potentially being discharged to surface
water in Dillenbaugh Creek near MW-25. It is not
understood how this discharge to the Creek is impacting
the plume. There is also a potential for additional
groundwater discharge points in Berwick Creek between
Labree Road and the confluence with Dillenbaugh Creek.
• A possible source for the contamination identified in the
Thurman Berwick Creek area includes a potential release
to Berwick Creek south of the Breen Property. If a
release did occur, it is unknown how far the released
contaminant migrated along the creek and where
deposition occurred. The vertical extent of impact to
creek bed soil/sediment should be assessed.
Install two monitoring wells along the plume axis downgradient of the
Breen Property between Labree Road and MW-25. Results of
groundwater sampling for transect of soil borings (RS-47, RS-48, and
RS-49) completed by Farallon in 2004 should be used for placement of
one well. A second transect consisting of three soil borings between
the RS-47/RS-49 transect and MW-25 should also be installed for
placement of the second well.
Install three to four monitoring wells downgradient of MW-25 along the
approximate plume axis. For determining well placement, install soil
borings along three to four transects perpendicular to the assumed
plume axis between Rice Road and Dillenbaugh Creek. Each transect
would consist of three to four borings. Groundwater samples would be
collected at four different intervals in each boring: approximately 5 feet
bgs, from 15 to 25 feet bgs, from 30 to 40 feet bgs, and from 40 feet to
the base of the aquifer, typically at 50 feet bgs Proposed well locations
should include between MW-25 and the suspected "leading edge" of
the plume, at or near the "leading edge" of the plume, and between the
"leading edge" and at a downgradient point(s) where the PCE
concentration is undetectable.
Advance two additional borings to the north between RS-47 and I-5 to
assess the extent of the plume from the Breen Property.
Advance two additional borings to the south of RS-49 to assess the
extent of the apparent plume from the Thurman Berwick Creek area
and to better assess the portion of the plume upgradient of PW-21.
Collect surface water samples at 10 to 12 locations in Dillenbaugh and
Berwick Creek between Labree Road and MW-28. This sampling
should be conducted in the dry and wet seasons to assess seasonal
effects on concentrations related to changes in groundwater table
elevation and changes in creek flow volume. In addition, collect
generally co-located groundwater samples along the west side of this
reach of Dillenbaugh Creek to evaluate the concentrations of
groundwater potentially being discharged. This could be conducted
using borings along the bank or more innovative approaches, such as
phytoscreening, (i.e., coring samples from mature trees along the creek
bank) (Sorek 2008).
Install four to six borings in Berwick Creek between Labree Road and
the confluence with Dillenbaugh Creek and collect two soil/sediment
samples from each boring. Borings should be completed into the silt
layer comprising the creek bed.

INTRODUCTION
EPA Region 10 has requested that Parametrix (Contractor) provide technical support for the development
of a Remedial Investigation/Feasibility Study (RI/FS) for the Hamilton/Labree Roads Groundwater
Contamination Site (Site) in Chehalis, Washington. The goal of this technical memorandum is to present
the results of a data usability review of available chemical data collected during historical investigations
completed at the Site. The technical memorandum also includes an evaluation of data collected in 2007
during groundwater monitoring and indoor air monitoring.
Table 1 presents a summary of relevant historical investigations conducted at the Site. The Contractor
anticipated that the data from these investigations could be used as presented in the respective original
data sources. However, this technical memorandum summarizes the efforts completed by the original
investigators to evaluate data quality and evaluates the usability of this third-party data for completing the
RI/FS.
The evaluation of data usability included reviewing available documentation to determine the following:
• Had a Quality Assurance Project Plan (QAPP), Sampling and Analysis Plan (SAP), or Field
Sampling Plan (FSP) been prepared for each investigation?
• What procedures were used to collect samples?
-------
TECHNICAL MEMORANDUM (CONTINUED)
• What analytical methods were used and who provided analytical services?
• Were the protocols presented in the QAPP, SAP, or FSP followed?
• Was chain-of-custody documentation prepared and was it available for review?
• Was data reviewed/validated and who completed the task?
• What were the results of the data review/validation and are reports available?
• Was an investigation report completed?
A detailed review of available QAPPs, SAPs, and FSPs was not conducted to determine if all procedures
presented in these documents had been followed. Instead, a cursory review of these documents was
completed and discussions on deviations from required sampling protocols presented in the corresponding
investigation documents were used to determine if/what procedures had been revised in the field.
Sampling and analysis methodologies described in this technical memorandum were primarily taken from
the final investigation documents completed for the Site.
True "data validation" would require a complete review of all relevant study documents, including
planning documents, analytical data packages, field notes, and data verification notes. As noted in the
Guidance on Environmental Data Verification and Data Validation (EPA 2002), these evaluation
procedures are not routinely performed for third-party data. In regards to the Site, obtaining all of the
necessary information to support a formal data validation effort would be particularly difficult, given the
number of investigators involved and the extended time period over which these investigations have been
conducted (i.e., greater than 10 years). Therefore, the effort documented in this technical memorandum
primarily consisted of reviewing the data quality evaluations included in the third-party investigation
reports. These reviews do not constitute an attempt to re-validate any of the third-party data; however, in
several cases, available quality control (QC) data were evaluated to confirm data quality where
information was limited.
DATA SOURCESAND EVALUATION
Reports, databases and other files containing historic chemical and physical data were received from the
EPA contractor (URS) and the S.C. Breen Construction Company (Breen) contractor, Farallon Consulting
(Farallon). These reports, databases and files contained data pertaining to contaminant evaluations
conducted between 1993 and 2004 on or in the vicinity of the Breen Property and the Hamilton Labree
Roads Impact Area (HRIA) source area by Washington State Department of Ecology (Ecology) and
contractors, EPA Region 10 and contractors, and Breen and contractors. In addition, a file search was
completed at Ecology's Southwest Regional Office to obtain any relevant data, reports, and other
information not previously included in the databases and files.
In addition, data recently collected by EPA Region 10 Contractor Parametrix and the EPA Emergency
Response Team (ERT) was also evaluated.
The following investigation reports and other data sources were reviewed:

The results of the data usability review are presented below in chronological order.
Washington Department of Health
In 1993 and 1994, eighteen private water supply wells (PW-1 through PW-18) were sampled for volatile
organic compounds (VOCs) (Ecology 1999a, 1999b). PCE was detected at six of these wells (PW-2, PW-
3, PW-4, PW-5, PW-7, PW-9). Five of these wells were re-sampled (PW-2, PW-3, PW-4, PW-5, PW-9)
in June of 1996. Some laboratory data sheets from 1993 is presented in the Ecology (1999a) Source
Investigation Report for the Site, but the remaining data was only available in various spreadsheets and
databases supplied to the Contractor.
No QAPP, SAP, or descriptions of the sampling methods used were available for review.
Samples from 1993 were analyzed by EPA Method 524.2 by the Washington Department of Health
Laboratory. No chain-of-custody documentation was available. No information on data
review/validation was available for these samples.
Washington Department of Ecology
Ecology conducted various investigations at the Site (SAIC 1997; Ecology 1999a; Ecology 1999b,
Ecology 2000) with a goal to locate the source(s) of PCE contamination.
SAIC 1997b
This report presented data for groundwater and soil samples collected in February/March 1997 (Phase I
investigation) and April/May 1997 (Phase II investigation). Sampling was conducted per the Final
Sampling and Analysis Plan for Hamilton/Labree Roads Perchloroethylene (PCE) in Groundwater Site,
Chehalis, Washington (SAIC 1997a). However, this SAP was not available for review and no discussion
of deviations from the proposed sampling methods was presented in the investigation report.
Sampling Methods: As a contractor for Ecology, SAIC collected subsurface soil samples throughout the
HRIA source area using a hollow-stem auger equipped with an 18-inch long, 2-inch diameter split-spoon
sampler. Soil samples were collected at five-foot intervals beginning five feet below ground surface. Soil
was screened for VOCs using a HNu™ photoionization detector (PID).
Several monitoring wells were installed and both monitoring wells and private wells were sampled.
Monitoring wells were purged using either disposable bailers (Phase I sampling) or a Grundfos Rediflow

2 submersible pump (Phase 2 sampling). All samples were collected using disposable hand bailers.
Samples for the private wells were collected using the dedicated well pump.
Data Analysis and Validation: Laucks Testing Laboratories, Inc. in Seattle, Washington conducted all
chemical analyses. Samples were analyzed for VOCs using EPA Method 8260. Chain-of-custody
documentation was included with laboratory reports in the investigation report.
A data review/validation summary was not included in the report; however, field QC sample results
(equipment rinsate blanks) were discussed and laboratory case narratives and data summary sheets were
included. A limited review of the available analytical QC data and laboratory case narratives indicated
acceptable results and no rejected data were identified. All data reported were judged to be acceptable for
further use.
Ecology 1999a
Ecology contracted Transglobal Environmental Geosciences Northwest, Inc. (TEG) of Lacey,
Washington to conduct additional site investigation. This investigation report presented data for soil,
groundwater, and surface water samples collected during a site investigation in March/April 1998. It also
includes historical data reported by the Department of Health in 1994 and 1996. No Quality Assurance
Project Plan (QAPP) or Sampling and Analysis Plan (SAP) were available for review.
Sampling Methods: Vadose zone soil samples were collected from borings B21 through B27 located near
private supply well PW-3, using Strataprobe™ direct-push technology. Samples were collected using an
18-inch long, 2-inch diameter split-spoon sampler lined with stainless-steel sleeves. The content of the
split-spoon sampler were transferred directly to glass jars.
TEG also collected shallow and deep groundwater samples from temporary borings (B1 through B20 and
B-23 through B27) near the intersection of Hamilton and Labree Roads. Samples were collected using a
combination of a peristaltic pump and syringe to help minimize VOC loss.
Surface water samples were collected from Berwick Creek sampling stations SW-1 through SW-3, and
the east end of the culvert emptying into unnamed ditch (SW-4). Samples were collected directly into
sampling containers at the approximate mid-point of the creek channel.
Data Analysis and Validation: TEG conducted all analyses on-site using a mobile laboratory. Samples
were analyzed for benzene, toluene, ethylbenzene, and xylene (BTEX) and/or specific halogenated
hydrocarbons using EPA Method 8010/8020. All samples were analyzed within 30 to 60 minutes of
collection. Chain of custody documentation was not included in the investigation report.
A data review/validation summary was not included in the report; however, laboratory data and QC
summary sheets were included, as well as a summary of TEG's QC procedures. No field QC data were
identified. A limited review of available analytical QC data, including an evaluation of method blank
results, surrogate recoveries, and analytical and field duplicate precision, indicated acceptable results and
no rejected data were identified. All data reported were judged to be acceptable for further use.
Ecology 1999b
This report presented data for soil, groundwater, and surface water samples collected between October
1997 and July 1998. Sampling was conducted per the Hamilton/Labree Soil Sampling and Ground Water
Monitoring Quality Assurance Project Plan (Ecology 1997). Based on a review of the QAPP and final

investigation report, it appears that most field and laboratory protocols were followed during the
investigation. However, no discussion of deviations for the QAPP was included in the investigation
report.
Sampling Methods: Ecology collected six soil samples near PW-9 using a JMC portable soil sampler in
January of 1998. The JMC sampler was equipped with a 3-foot long, 1-inch diameter sampling tube lined
with stainless-steel sleeves. Samples were collected from 1-3 feet and 4-6 feet below ground surface.
The content of the sleeves was emptied into a stainless steel bowl and homogenized before being placed
into sampling containers.
Ecology also conducted quarterly monitoring of permanent monitoring wells (MW-1 through MW-9),
monitoring and recovery wells (MWR-1 through MWR-7), and private wells (PW-2 through PW-22).
Groundwater samples from the monitoring wells were collected using a stainless-steel submersible pump
and a low-flow sampling technique. Samples for the private wells were collected using the dedicated well
pump.
Surface water samples were collected from Berwick Creek sampling stations SW-1 through SW-3.
Samples were collected directly into sampling containers at the approximate mid-point of the creek
channel.
Data Analysis and Validation: The EPA Manchester Environmental Laboratory in Port Orchard,
Washington conducted all analyses. Samples were analyzed for VOCs using EPA Method 8260. Chain-
of-custody procedures were referenced in the investigation document, but no chain-of-custody
documentation was available for review.
A data quality review summary and laboratory case narratives were included in the report. All data were
judged to be acceptable for further use; with the exception of sample results from private well PW-9
collected January and April 1998. These data were rejected because they were not representative of site
conditions, as water from the contaminated well was diluted by an alternate water supply that also fed the
water distribution piping at that location. As the alternate supply was disconnected, PCE concentrations
returned to historic levels observed in samples collected prior to an installed wellhead treatment system
(Ecology 2000).
Ecology2000
This report presented data for quarterly groundwater monitoring samples collected in February and July
1999. No QAPP or SAP was available for review; however, a description of the sampling and analytical
methods used was included in the investigation document.
Sampling Methods: Ecology continued quarterly monitoring of permanent monitoring wells (MW-1
through MW-9), monitoring and recovery wells (MWR-1 through MWR-7), and private wells (PW-2
through PW-22). Groundwater samples from the monitoring wells were collected using a stainless-steel
submersible pump and a low-flow sampling technique. Samples for the private wells were collected

GeoEngineers2001
This report presented data for groundwater and soil samples collected during remedial action (including
drum removal activities) and monitoring activities at the Breen Property by GeoEngineers between July
1999 and July 2000. No project QAPP or SAP was available for review.
Sampling Methods: Soil samples were collected from Strataprobe™ sampling locations (SP-1 through
SP-8) on the Breen Property. Samples were collected using 1.5-inch, 2-inch, or 3-inch split spoon
samplers.
Samples were also collected from test pits (TP-1 through TP-7) installed around Building B prior to drum
excavation and removal using a backhoe. Additional soil samples were collected from the drum
excavation (Building B) using an excavator. Samples from the test pits and excavation were collected
from the center of the backhoe/excavator bucket using stainless steel hand tools. Soil samples from the
excavation were screened using an organic vapor monitor (OVM) and field testing for oil sheen by
placing soil in water.
Groundwater samples were collected from Strataprobe™ borings (SP-1 through SP-8) at depths of 15 and
40 feet using a peristaltic pump with polyethylene tubing or a 60 cubic centimeter syringe with a shutoff
valve at the end of the polyethylene tubing.
Data Analysis and Validation: TEG (onsite mobile laboratory), Sound Analytical Services, Inc. in
Tacoma, Washington, and North Creek Analytical, Inc. in Bothell, Washington conducted the chemical
analyses. Soil and groundwater samples collected from the Stratatprobe™ borings and test pits were
analyzed for VOCs using EPA Method 8021B. In addition, two soil samples were also analyzed for
VOCs using EPA Method 8260, total petroleum hydrocarbons using WTPH-HCID, semivolatile organic
compounds (SVOCs) using EPA Method 8270, and metals using EPA Series 6000/7000 methods. Chain-
of-custody documentation was included with laboratory reports in the investigation report.
A data quality review summary was included in the report. All data were judged to be acceptable for
further use, with the exception of positively-detected methylene chloride (dichloromethane) data for these
samples. These data were rejected due to high analyte levels seen in the corresponding analytical method
blanks. Methylene chloride data (detections only) for the 2001 GeoEngineers groundwater and soil
samples will be excluded from use in completing the RI/FS.

Phase IV soil investigations were conducted to assist in the evaluation of a proposed water supply piping
route. Sampling and analysis was conducted following Phase IV Hamilton-Labree Quality Assurance
Plan (E&E 2001b); however, this document was not available for review. According to information
presented in the investigation report, sampling and analysis was conducted per the QAPP except for a
deviation related to the purge method used for PW-4 (see discussion below).
Sampling Methods: Phase IV soil investigations were conducted to assist in the evaluation of a proposed
water supply piping route. Ninety soil borings were installed (GP-102 through GP-191) and samples
collected every 50 feet along Hamilton Road North to the intersection with Labree Road using a
Geoprobe™ direct-push technique.
Additional groundwater monitoring was conducted as part of Phase IV investigations during
October/November of 2001. Sampling locations included several private wells (PW-1 through PW-9,
PW-16, PW-17, PW-21 through PW-37), monitoring wells (MW-1 through MW-10), and
monitoring/recovery wells (MWR-1 through MWR-11). Monitoring wells were sampled using dedicated,
submersible EasyPumps, except on the Breen Property where dedicated bailers were used.
Samples for the private wells were collected from an outside spigot (before the treatment unit) using the
dedicated well pump. The sample from PW-7 was collected directly from the well using a dedicated
EasyPump. The sample from PW-4 was collected using a low-flow purge and sampling method. All
other groundwater samples were collected following purging of three casing volumes before sampling.
Data Analysis: Soil and groundwater samples were submitted to OnSite Environmental for VOC analysis
using EPA Method 8260. In addition, soil samples collected from four of the borings were analyzed for
semi-volatile organic compounds (SVOCs) using EPA Method 8270. One soil sample was also submitted

TECHNICAL MEMORANDUM (CONTINUED)
Farat/on 2003
This report presented data for soil, groundwater, surface water, and soil gas samples collected during a
Phase I RI/FS Investigation conducted from July to December 2002 at the Breen property. Sampling and
analysis was conducted following the Phase I Investigation Work Plan, Sampling and Analysis Plan,
Health and Safety Plan (Farallon 2002). This document included the QAPP and FSP as appendices.
A soil vapor survey was also conducted during the Phase I investigation, but was not included in the
Work Plan. No sampling plan was available for review; however, a statement in the Remedial
Investigation/Feasibility Study Work Plan, Hamilton/Labree Roads Groundwater Contamination
Superfund Site (Farallon 2003) stated that the soil vapor survey was approved by EPA.
Sampling Methods: Soil samples were collected at reconnaissance points (RS-1, RS-2, RS-5, RS-8, RS-
9, RS-12, and RS-16) and monitoring wells (MW-18, MW-19, MW-12, MW-23, MW-24, and MW-25)
on the Breen Property. Soil sampling was completed primarily using a hollow-stem auger. For the
reconnaissance borings (RS-1 through RS-24), the FSP stated that Geoprobe™ or Strataprobe™ would be
used for boring installation; however, because of apparent problem with shallow refusal using the push-
probe technology, most borings were installed using a hollow-stem auger. In addition, the FSP called for
collection of continuous soil samples from the surface to 50 feet below ground surface in well borings
(MW-18, MW-19, MW-21, and MW-23 through 25). Based discussions with EPA on July 9, 2002, soil
samples from groundwater monitoring well borings were collected at approximately 5, 10 and 45 feet
below ground surface. The reason for this change was because of slow sample collection with continuous
coring and the associated resulting schedule delays.
Soil vapor samples were also collected from 5 feet below ground surface at several locations in the area of
RS-1, RS-2, and RS-7. No information on the sampling method was available.
Groundwater monitoring and sampling occurred during June/July 2002 and November 2002. Samples
were collected from existing and new monitoring wells (MW-1 through MW-25, MWR-1 through MWR-
11), private wells (PW-7, PW-21) and reconnaissance groundwater stations (RS-1 through RS-24) on or
downgradient of the Breen Property. Sampling was conducted using low-flow sampling procedures using
a peristaltic pump and syringe method to reduce VOC loss.
The Phase I Investigation also included the establishment of six surface water monitoring stations; five
along Berwick Creek (SW-6 through SW-10) and one on the unnamed ditch (SW 5). Sampling of these
locations occurred during July 2002 and November 2002. Surface water samples were collected using a
peristaltic pump with dedicated tubing from mid-channel at approximately 0.6 of the depth from the
stream surface to the stream bottom.
Data Analysis and Validation: OnSite Environmental, Inc. conducted all chemical analyses. All soil,
groundwater, and surface water samples collected and submitted for the Phase I Investigation were
analyzed for the presence of VOCs by EPA Method 8260B. Analyses for additional contaminants,
including SVOCs using EPA Method 8270 and gasoline- and diesel-range total petroleum hydrocarbons
using NWTPH-Gx and NWTPH-Dx were also conducted for selected groundwater and surface water
samples collected in areas downgradient of potential and/or confirmed sources.
Soil vapor samples were analyzed for PCE and TCE by EPA Method 802IB. No information on the
laboratory that conducted these analyses was available.

TECHNICAL MEMORANDUM (CONTINUED)
Data validation reports were prepared by an independent consultant, EcoChem, Inc. in Seattle,
Washington and it was determined that the analytical data met the QA/QC requirements set forth in the
project work plan. Final data validation reports were submitted to EPA under separate covers, along with
the complete laboratory data packages. All data were judged to be acceptable for further use, with the
following exceptions:
• VOC (EPA 8260) data for sample RS-071002-01. The initial (July 17, 2002) analytical result for
PCE exceeded the linear calibration range of the instrument. The sample was reanalyzed twice
(July 22 and 24, 2002), but the results were substantially lower than the original result.
Therefore, in an effort to be conservative, the analytical result from the original analysis was
considered acceptable, while the reanalysis results were rejected ("R" qualifier) and judged to be
unsuitable, due to potential low bias from sample inhomogeniety or volatilization. These "R"-
qualified data will be excluded from use in the RI/FS.
• VOC (EPA 8260) data for sample PW-080602-05. The initial analytical result for PCE exceeded
the linear calibration range of the instrument. A lOOx dilution (PW-080602-05DL) was analyzed
on August 20, 2002. The original lx PCE result was rejected ("DNR" qualifier), while the results
for all other compounds (i.e., those excluding PCE) from the lOOx dilution were also rejected
("DNR" qualifier). These "DNR"-qualified data will be excluded from use in the RI/FS.
• VOC (EPA 8260) data for samples PW-080602-06, -06DL, -07, -08, -09, -10, and PW-080702-
01, through -09. These sample results were rejected ("DNR" qualifier) due to a laboratory error
and these samples were re-sampled and re-analyzed at a later date. These original "DNR"-
qualified data will be excluded from use in the RI/FS.
Chain-of-custody documentation was available for all sampling conducted.

URS2004
This report presented data for soil, creek soil/sediment, and ground water samples collected during the
EE/CA field investigation conducted August through November 2003 by URS for EPA (URS 2004).
Sampling and analysis was conducted following the Quality Assurance Project Plan EE/CA Investigation,
Hamilton Road Impact Area, Hamilton-Labree Roads Superfund Site, Chehalis, Washington (URS 2003).
A summary of the actual sampling methods used are described in detail in Appendix A of the Draft
(Revision 1) Engineering Evaluation/Cost Analysis Report, Hamilton Road Impact Area, Hamilton-
Labree Roads Superfund Site, Chehalis, Washington (URS 2004) and discussed briefly below. Appendix
A also includes information on deviation in sampling procedures from the QAPP.
Sampling Methods: Soil sampling was conducted using a Geoprobe™ in the upper 30 feet of the shallow
aquifer, while a hollow-stem auger drill rig was used to explore the lower 20 feet of the shallow aquifer to
collect relatively undisturbed soil samples and to install permanent monitoring and recovery wells.
Sample collection from Geoprobe borings was completed using a Macro Core Soil Sampler. Sampling
with the hollow-stem auger was accomplished using a Dames & Moore split spoon sampler. Soil vapor
samples were collected using a Geoprobe™ and a vacuum pump.
During this investigation groundwater samples were collected from Geoprobe™ and hollow-stem auger
borings and from new monitoring wells. Depth-specific groundwater samples were collected at the
Geoprobe™ locations using the Screen Point 16 Groundwater Sampler. Groundwater samples were
collected from hollow-stem auger borings using the hydropunch method, which involves driving a
sampler ahead of the lead auger and collecting a small, discrete volume of groundwater. The wells were
sampled using a low-flow pneumatic bladder pump set at the depth in the well screen where the highest
PCE concentrations were found in discrete water samples.
Creek bed soil/sediment and bank samples were collected along Berwick Creek and the unnamed ditch.
A hand-held Geoprobe™ tool called a Large Bore Sampler, consisting of a 24 inch-long, 1 inch-diameter
steel sample tube with a steel drive shoe and an acrylic liner, was used for sample collection.
Data Analysis and Validation: The ESAT mobile laboratory conducted analysis of soil and groundwater
samples collected from soil borings using an approved field screening procedure (ESAT PCE analysis).

from volatilization of contaminants from groundwater to indoor and ambient air.
EPA 2008, Lockheed Martin 2008
Sampling was conducted per the Quality Assurance Project Plan for Hamilton Labree Vapor Intrusion,
Chehalis, WA. (EPA 2007b).
Sampling Methods: A total of 35, 24-hour composite samples (including one trip blank) were collected
including 14 indoor air, seven crawl space, six sub-slab, and seven ambient air. Samples were collected
using 6-liter Summa canisters. Sub-slab air samples were collected from beneath the concrete floor slabs
by coring through the concrete slab and installing a temporary soil gas well near the center of the slab.
Data Analysis and Validation: All air samples were analyzed for VOCs including PCE, TCE, cis-1,2-
DCE, trans-1,2-DCE, 1,1-DCE, methylene chloride, and vinyl chloride using EPA Method TO-15 SIM.
Analyses were conducted by Columbia Analytical Services for Lockheed Martin Technology Services in
Edison, New Jersey. Data validation was completed by Lockheed Martin; no data were rejected and all
data were found to be acceptable.
Chain-of-custody documentation was available for all sampling conducted.
GENERAL COMMENT ON SOIL ANALYSIS
Based on the information reviewed, soil samples collected for VOC analysis did not appears to have been
preserved using the protocols under EPA Method 5035A. The primary goal of this VOC collection and
preservation technique is to minimize the direct volatilization of contaminants in soil to the atmosphere.
Since EPA Method 5035A does not appear to have been utilized during soil sample collection, there is a
possibility that VOC analytical results are biased low, especially for samples collected from the gravelly
materials that comprise the shallow aquifer.
GENERAL COMMENT ON MI SSI NG SAM PL E LOCATION AND DEPTH
INFORMATION
The horizontal coordinates of some sample locations are missing. Analytical data associated with these
samples is unusable since the data cannot be located at the Site. Samples with unknown locations
include: AB-9, AB-10, B9, B10, B12, RS-32, GP-161, PW-10, PW-11, PW-13, PW-18, PW-19, PW-20,
SG1-11, SG1-14 through SG1-19, SG2-10 through SG2-14, SG-206, and SG-210. Missing sample depth
information is also problematic as any analytical data obtained at a known horizontal position cannot be
located vertically.
In addition, the use of groundwater data from wells with long screens where the sample collection depth
is unknown is problematic since it is not clear what zone within the shallow aquifer the sample

concentration may represent. The difficulty with using this data is demonstrated by the results obtained
from several wells which were vertically characterized by using low-flow sampling methods and placing
the pump at different depths within the well screen. In MW-R8 and MW-602, setting the pump at
different depths within the screen clearly made a significant difference in the concentration, indicating a
strongly stratified plume. However, in MW-R11 the difference in concentrations was not observed with
changes in depth. It is unclear why these varying results were obtained. Based on observed results from
wells such as MW-R8 and MW-602, using data from wells with long screen intervals where the sample
depth is unknown may compromise the validity of trend plots and modeling efforts.
The usability/interpretation of data obtained from groundwater samples collected from private wells is
also an issue for several reasons. First, well logs are not available for many of the private wells such that
the depth and screen interval of the well is unknown. For those private wells where well logs are
available, data has typically not been evaluated vertically by looking at well construction information
such as screen interval depths and the type of screen in use (e.g., perforated interval or open end finish).
Determining this information could make a difference in how this data is used for modeling efforts and
other evaluations of the nature and extent of contamination.

INTRODUCTION
EPA Region 10 has requested the Parametrix Team (Contractor) to provide technical support for the
development of a Remedial Investigation/Feasibility Study (RI/FS) for the Hamilton/Labree Roads
Groundwater Contamination Superfund Site (Site) in Chehalis, Washington. The purpose of this technical
memorandum is to present the results of a desktop land use survey of the Site to assess potential impacts
to current and future land-use from contaminated plume migration.
LAND USE INFORMATION
The Lewis County website (http://www.co.lewis.wa.us') and the City of Chehalis website
("http ://www.citvofchehalis .com) were contacted to obtain available information on both current and
future land use for the Hamilton Road Impact Area (HRIA) and Breen Property source areas, and the area
downgradient of the source areas. Figures from the Lewis County Comprehensive Plan (June 1, 1999,
amended April 4, 2002, December 22, 2008, August 2009, and December 27, 2010), the Lewis County
Official Zoning Map, and the City of Chehalis Official Zoning Map were reviewed. Additional
information related to zoning was also reviewed at the Lewis County website. A discussion of the
findings is presented in the following sections.
-------
TECHNICAL MEMORANDUM (CONTINUED)
Current Land Use
The portion of the Site containing the HRIA and Breen Property source areas is within the City of
Chehalis Urban Growth Area (UGA) boundary and is zoned commercial general (CG) [Attachment 1,
City of Chehalis Official Zoning Map].
Current land use downgradient of the HRIA and Breen Property source areas consists primarily of
residential (Rural Development District [RDD]-20) and Agricultural Resource Lands (west of Rice
Road). Figures 4-la and 4-la_2 in Attachment 1 show the existing land use. There is a small area in the
far northwestern corner of the area bounded by 1-5 and Rogers Road (just south of the City of Chehalis)
that is currently shown as Public/Quasi Public. This area is located approximately 5,000 feet northwest of
the current known extent of the groundwater plume. This area is shown as being within the City limits on
the 2009 Lewis County Official Zoning Map and is zoned as a Park (Stan Hedwall Park) on the City of
Chehalis Official Zoning Map. A small area adjacent to the northeastern boundary of the Park and
adjacent to an 1-5 interchange (Exit 76) in this area is shown as City UGA on the 2009 Lewis County
Official Zoning Map and is zoned as Commercial Freeway (CF) on the 2009 City of Chehalis Official
Zoning Map.
Future Land Use
Future land use at the HRIA and Breen Property source areas is anticipated to be similar to current land
use, which is CG. A new freeway interchange was recently constructed where LaBree Road crosses
Interstate 5 (1-5) just north of the Breen Property source area. Additional commercial use of this area is
anticipated due to the completion of the interchange.
Future land use in the area downgradient of the HRIA and Breen Property source areas is anticipated to be
similar to current land use with the exception of one area: the small section located northeast of the
Parkand adjacent to the 1-5 interchange (Exit 76), that is shown as undeveloped and Public /Quasi Public
on the Existing Land Use Map (see Attachment 1). This area is shown as City UGA on the Lewis County
Future Land Use of Rural Lands Map (Figure 4.17a) and zoned as CF on the City of Chehalis Official
Zoning Map. The Lewis County future land use map is provided in Attachment 2.
Bob Nacht (personal communication, October 8, 2007), the City of Chehalis Community Development
Director, was contacted regarding future land use at the Site.
Most of the area downgradient of the HRIA and Breen Property source areas is not within the Chehalis
UGA (except for a small area west of the HRIA and south of the Breen Property, which is zoned CG [see
Attachment 1]) and probably would not be considered so unless commercial development approached the
City of Chehalis. With the construction of the new I-5/Labree Road interchange, this could happen in the
near future. Either general commercial or freeway-oriented commercial zoning would eventually be
applied to the area in the vicinity of the new interchange. However, the area around and downgradient of
the Hamilton/Labree Roads intersection is located in an environmentally sensitive area and less
challenging areas to develop have been sought. Because of floodplain issues, it is unlikely that any
residential zoning would be adopted by the City of Chehalis for the properties nearer to the interchange.
The properties that lie further from the freeway frontage (including along Rice Road) would probably
remain residential.
There have been discussions in the past regarding commercial development of the dairy farm. The cost of
obtaining utility service, and the potential for flooding in that area would probably be a deterrent to

anything but commercial development. It is unlikely that any major residential subdivisions would occur
in that vicinity.
If the area downgradient of the source areas is designated Chehalis UGA in the future, the City of
Chehalis could establish development conditions that would restrict the use of onsite groundwater. The
City's water system would become eligible to be extended to that area. However, this could make the cost
of development in the area high.

Lewis County Zoning District Information
This guide is intended to briefly describe the major zoning districts in Lewis County. Specific information about each zone,
subdivision requirements or development regulations can be obtained from the Planning Division at
(360) 740-1146 or at 2025 NE Kresky Ave. in Chehalis.
Agricultural Resource Land: This zone is primarily devoted to commercial production of aquaculture,
horticultural, viticultural, floricultural, diary, apiary, vegetable, or animal products or berries, grain, hay, straw,
turf, seed, Christmas trees, or livestock. Agricultural resource lands are currently subject to an order of
invalidity imposed by the Western Washington Growth Management Hearings Board. For more information
please contact the Planning Division at (360) 740-1146.
CC (Crossroads Commercial): This is a commercial zone that only allows residential development on existing
lots. For more information on allowed uses please consult LCC 17.42.030. The purpose of the CC zone is to
identify small, concentrated areas that have historically provided commercial services to rural residents and
allow infill development.
City Limits: This zone is intended for residential and commercial use. They are managed by the individual
city. For more information, please contact the individual city's planning department.
FC (Freeway Commercial): This is a commercial zone that provides service to the traveling public along
major transportation routes. The purpose of this zone is to provide areas for new commercial development and
provide convenient access to transportation routes. Allowed land uses include all types of commercial
development and limited industrial development, residential uses are not allowed. For more information please
see LCC 17.42.030.
Forest Resource Land: This zone is intended for land primarily useful for growing trees and Christmas
trees for commercial purposes. Forest resource lands are currently subject to an order of invalidity
imposed by the Western Washington Growth Management Hearings Board. For more information please
contact the Planning Division at (360) 740-1146.
Mineral Resource Land: This zone is primarily devoted the extraction of minerals of commercial
significance. Mineral resource lands are currently subject to an order of invalidity imposed by the Western
Washington Growth Management Hearings Board. For more information please contact the Planning Division
at (360) 740-1146.
RDD (Rural Development District): This is a mixed-use zoning district that allows a number of different land
uses such as single family residential, resource uses and limited types of commercial activity. For more
information please consult LCC 17.42.040. There are three density designations for this zone that determine the
potential for future subdivision in this zone. RDD-5 allows a density of one dwelling unit per five acres for
subdivision purposes. RDD-10 allows a density of one dwelling unit per ten acres for subdivision purposes.
RDD-20 allows a density of one dwelling unit per twenty acres for subdivision purposes. The purpose of the
RDD zone is to achieve a variety of lot sizes, protect rural character, and protect small rural businesses that have
historically served the people of Lewis County.
RRC (Rural Residential Center): This zone represents areas that have historically developed at densities and
intensities greater than rural development, but outside of urban areas. Residential uses and very limited types of
business uses are allowed in this zone. For more information please see LCC 17.42.030. There are four
designations for this zone that determine average density of the established pattern of development and
minimum lot size. RRC-R.5 allows a maximum density and minimum lot size of one dwelling per an acre.
RRC-R1 allows a maximum density and minimum lot size of one dwelling per acre. RRC-R2 allows a
-------
maximum density and minimum lot size of one dwelling per two acres. And RRC-R10000 allows a maximum
density and minimum lot size of one dwelling per 10,000 sq. ft. Please note that minimum lot sizes are allowed
only if compliant with current environmental health regulations.
STI (Small Town Industrial): This zone allows for industrial development, resource uses, and limited types of
commercial and residential development. For more information please consult LCC 17.42.030. The STI
designation was created to assure that areas historically devoted to intensive employment activities are protected
and to assure the continuation of locations that support long-term commercially significant resource activities.
STMU (Small Town Mixed Use): This zone allows commercial and residential activities. For more
information please consult LCC 17.42.030. The STMU designation is designed to assure infill development
that is consistent with the surrounding uses, existing public facilities and character of the area.
STR-4 (Small Town Residential-maximum four dwellings per acre): This zone promotes and protects
areas that have been historically exclusively residential in character. Allowed uses in this zone include
various types of residential development and very limited types of business use. For more information please
see LCC 17.42.030.
PTSA (Tourist Services Area): This is a floating zone that may be created through a master plan process.
PTSA zones are intended to support tourist and recreation areas. Currently there are no designated PTSA
zones in Lewis County.
UGA (Urban Growth Area): A designated area for urban growth. Urban growth areas are within county
jurisdiction but when attached to an incorporated city, development within this zone is subject to the rules and
regulations set forth in that city's Comprehensive Plan and Development Regulations.

Introduction
On May 10, 2010, a team from the U.S. Environmental Protection Agency Region 10
office measured water levels and assessed the condition of most of the monitoring wells
at the Hamilton/Labree Roads Superfund Site in Chehalis, Washington. A subset of
wells had been sampled and measured in 2007, but many of the wells had not been
measured since 2004. Additionally, two private wells were also measured in areas with
poor monitoring well coverage. The site is in the process of completing the Remedial
Investigation and Feasibility Study (RI/FS) for the Hamilton Road Impact Area (OU 1).
EPA site managers desired an up-to-date water level measurement and an assessment of
the condition of site wells. The cost of any selected remedial action could be impacted if
many of the monitoring wells need replacement or repair.
The field personnel included Tamara Langton, Remedial Project Manager for the site,
and Marcia Knadle, Office of Environmental Assessment (OEA) hydrogeologist for the
site, as well as OEA hydrogeologists Bernie Zavala and Rebecca Gerhart.
The site consists of two operable units: OU 1 is the Hamilton Road Impact Area (HRIA),
a tetrachloroethylene (PCE) DNAPL source area along and immediately downgradient of
Berwick Creek in the eastern portion of the site, and OU 2 includes the suspected PCE
source areas at the Breen Property and Thurman Berwick Creek properties, as well as the
plume extending downgradient to the north-northwest (see Figure 1). Site groundwater
flow direction is generally west-northwest between the HRIA and Labree Road, and then
turns north-northwest downgradient of Labree Road, generally following the surface
water features, Berwick and Dillenbaugh Creeks. The PCE plume is in a shallow aquifer
comprised of glacial outwash deposits, mainly heterogeneous silty sands and gravels with
occasional silt lenses. Groundwater seepage velocities are likely within the range of 50
to 150 feet/year. The aquifer occurs generally between 5 and 50 ft deep and is stratified
over much of the site, with the upper and lower halves of the aquifer exhibiting
dramatically different concentrations over much of the site.
Water Level Measurements
Field data and observations, as well as basic information about site wells, are summarized
on Table 1.
Monitoring wells
Water levels were measured from markings at the top of the inner PVC casing with an
electric water level sounding device. If no marking was visible, the measurement was
taken from the north edge of the casing. Water levels and notes as to the condition of
wells were recorded in field notebooks.
Besides measuring the water levels, the field crew replaced most of the locks, many of
which either had no key or were in such poor condition that they had to be removed with
2
-------
bolt cutters. In many of the wells with flush mount completions, there was nothing for
the locks to anchor to. In this case, the well cap was simply lifted in order to access the
well, and any existing locks were left in place "for show." If there was no lock in place,
none was left "for show." No lock was installed on one well with an above-ground well
completion because there was a yellow jacket nest in the well housing. This well is
located within a locked fenced area, so the risk of well tampering is low. The
replacement lock numbers were generally recorded in the field notebooks for future
reference, but this was overlooked in the case of a few wells.
Three flush mount monitoring wells located on the Breen property (MW-27, MW-29, and
MW-30) have caps that require a special tool to open. EPA doesn't have this tool, so the
field team was unable to access them. The wells appear to be in good condition. It's
possible that some of the other wells that could not be accessed on the Breen OU would
also require this tool to open.
Three monitoring wells were difficult or unsafe to access and were not measured or
assessed. Two of them (MW-9 and MW-10) are located between Berwick Creek and the
southwest edge of 1-5 and would have required either parking along the freeway to access
or crossing Berwick Creek, which had relatively high flow at the time. One (MW-28) is
located far downgradient, and EPA had no access agreement with the property owner.
Private Wells
Three privately owned wells were selected for water level measurement because they
help define the southern/southwestern boundary of the plume: one currently used
domestic well located west of the downgradient portion of the plume, one unused former
domestic well located on the southwestern margin of the plume, and one unused former
dairy well located near the south edge of the plume south of the source areas. The
elevations of the tops of all 3 wells had been surveyed previously. Water levels were
measured from the well cap with a steel tape marked with chalk. The dairy well was
inaccessible because it was in a low concrete box surrounded by manure slurry, and the
concrete box itself was flooded with water to the top of the open casing. It was deemed
unsafe to access.
Water Level Surface Mapping
Water level contours were hand drawn on maps. Water levels in the two measured
downgradient wells are consistent with the site-wide gradient pattern shown on historical
maps (see Figure 1). No site-wide map for May 2010 is presented because the
combination of the inclusion of PW-34 and the absence of a measurement from farthest
downgradient monitoring well MW-28 (to which the team was unable to obtain legal
access) skews the downfield water level contours to the west. The contours in the
vicinity of the source areas (Figure 2) generally compare well to earlier water level maps,
even with many missing wells. However, there are some differences. In particular, the
loss of access to the wells northeast of 1-5 and in the southern portion of the HRIA limits
and slightly alters the gradient pattern in the HRIA. The water level in MW-32 was so
3
-------
inconsistent compared to nearby wells that it was largely ignored. The water level in this
well has also been anomalously high in earlier water level measurements.
Well Network Status
Many wells were found to be inaccessible for a variety of reasons. Several have been
graveled over, either because they are located along road rights-of way where shoulders
have been re-graded or because they are located in parking lots which have had additional
gravel spread over them. It's possible these wells could be relocated with the use of a
metal detector and excavated. However, the upgradient wells located along the northeast
shoulder of 1-5, may be buried too deeply, especially the northern ones, which are likely
beneath the buildup for the new Labree Road exit ramp. In any event, these wells are
difficult to access because of the safety issues related to parking along 1-5. If they are
located and excavated, they should be abandoned.
Two wells (MWR-11 and MW-607), located on the former United Rentals property, have
been paved over by parking lot asphalt. These wells could probably be relocated, but it
would be difficult to excavate them out. The well cap for one well (MWR-10), located in
another parking lot on the same property, has been damaged and can't be removed. It's
possible a well driller could remove and replace the cap.
One well (MW-31) was apparently buried under a 3-4 ft high pile of clayey dirt some
time before the July 2007 sampling event. It's also possible that it's under some old
boards and other wood debris along Berwick Creek, but the dirt pile matches the
surveyed location better. This well could be excavated.
The condition of the monitoring well network in the area of the HRIA and the Breen and
Thurman Berwick properties is summarized on Figure 5.
Recommendations
Excavate buried monitoring wells and either repair/rehabilitate them or properly
abandon them per WAC 173-160-415. This may not be practicable for the buried wells
on the NE side of 1-5. Moreover, because the groundwater is not contaminated in that
area, there are no serious implications associated with leaving these wells in place.
Abandon wells with long screens, particularly wells in the HRIA source area. There
are several wells (MW-600 through MW-608) along Hamilton Road in the HRIA and
immediately downgradient that were installed by URS in 2003. They were intended to be
extraction wells and were screened across the entire shallow aquifer. Michael Meyer at
URS (Pers. Comm., 2010a) says that URS had recommended at the time of drilling that if
the wells were not promptly put into service as extraction wells, they should be
abandoned so as not to provide pathways for contamination to migrate vertically within
the aquifer. This recommendation was not implemented by EPA, which may have lead to
4
-------
some migration of PCE from the upper zone to the lower zone of the shallow aquifer,
especially if local vertical gradients are downward or if mobile PCE DNAPL can enter
the wells. (There are very few well clusters across the site, so EPA's understanding of
vertical gradients is very limited. There's some indication that they may vary with
proximity to the creeks, but this may vary seasonally and/or along the creek reach.) The
primary implication is that the 2003-2004 plume characterization data EPA is using as
the basis for its RI/FS may no longer be accurate: the deeper zone in OU 1 may be more
contaminated than EPA realizes. Moreover, the usefulness of the water levels is
somewhat limited since they integrate water levels within the aquifer. As such, they may
not compare well to water levels collected in wells with more restricted screened
intervals. Unless these wells would be used as part of the selected remedy, they should
be abandoned, even after several years. Other long screened wells installed earlier in the
HRIA should also be abandoned, including MWR-8, MWR-9, MWR-10, and MWR-11.
In addition, there is one long-screened well on the Breen Property, MW-34. This well is
located in the most contaminated area on the Breen Property and should also be
abandoned.
Resurvey the remaining monitoring well network. Monitoring wells MW-33 and
MW-34 have apparently never been surveyed vertically, although horizontal survey
information exists. Consequently, although the water levels were measured, groundwater
elevations cannot be determined. MW-33 is especially important as part of one of the
few existing shallow aquifer well clusters. Surveying it would provide a vertical gradient
measurement close to the HRIA. MW-34 should be surveyed prior to any abandonment
in order to make the existing water level measurements usable. In addition, there are
several wells with water levels that appear anomalous relative to the mapped piezometric
field, in particular MW-32 and MW-5. Minor inconsistencies (perhaps up to a few tenths
of a foot) may be due to the wide range of screened intervals and the presence of minor
vertical gradients over portions of the site. Larger inconsistencies suggest either a
measurement error or that the well casing elevation has changed since 2004. Finally, a
number of wells have been graded over or otherwise possibly disturbed in ways that
could change their wellhead elevation.
Acquire the special tool to open the three wells (and possibly more) that require it.
Scott Elkind (Parametrix) (Pers. Comm., 2010b) says that they were able to open some of
those wells in 2007 using a 5/16" hex wrench (which we didn't have), so that could also
be attempted. However, the tool designed to work with those caps would probably work
better and be less likely to strip the bolts, so EPA should contact a well driller to acquire
one.
Drill two new piezometers on properties to the northeast of 1-5 for water levels only.
These piezometers should have above ground completions if at all possible, since flush
mount completions are apparently much more difficult to maintain long term. These
locations appear to be important for defining the flow field in the area of the HRIA PCE
source.

2. Soil type designations are interpretations based on field characterization of discrete soil samples.
3. Elevations are based on interpolation from Lewis County PUD topographic data, not site-specific ground surveys.
4. The groundwater sample from the installed well MW-602 exhibits a lower PCE concentration than nearby discrete
groundwater samples. This lower value was not used for contouring on this cross-section.

MEASUREMENT OF WATER LEVEL
AND WELL VOLUME
• Prior to sampling, the static water level
and total depth of the well will be
measured with a calibrated weighted line.
Care will be taken to decontaminate
equipment between each use to avoid
cross contamination of wells.
• The number of linear feet of static water
(difference between static water level and
total depth of well) will be calculated.
• The static volume will be calculated using
the formula:
V = Tr*(Q.163)
Where:
V * Static volume of well in gallons;
T e Depth of water in the well, measured in
feet:
r = Inside radius of well casing in inches;
and 0.163 s A constant conversion factor
which compensates for i*h factor for the
conversion of the casing radius from indies
to feet, the conversion of cubic feet to
gallons, and (pi).
1 well volume (v) = gallons.

MEASUREMENT OF WATER LEVEL
AND WELL VOLUME
• Prior to sampling, the static water level
and total depth of the well will be
measured with a calibrated weighted Bne.
Care win be taken to decontaminate
equipment between each use to avoid
cross contamination of wells.
• The number of linear feet of static water
(difference between static water level and
total depth of well) will be calculated.
• The static volume will be calculated using
the formula:
V*Tr*(0.163)
Where:
V e Static volume of well In gallons;
T s Depth of water in the wed, measured in
feet;
r s Inside radius erf well casing in indies;
and 0.163 = A constant conversion factor
which compensates for r*h factor for the
conversion of the casing radius (ram inches
to feet, the conversion of cubic feet to
gallons, and (pi).
1 well volume (v) = gallons.
