Introduction
Ecology and Environment, Inc., (E & E) was tasked by the United States
Environmental Protection Agency (EPA) to provide technical support for
completion of Preliminary Assessments (PAs) at several properties in West Salem
in Salem, Oregon. E & E completed PA activities under Technical Direction
Document (TDD) Number 13-04-0002, issued under EPA, Region 10, Superfund
Technical Assessment and Response Team (START) Contract Number EP-S7-06-
02 and TDD 13-09-0016, issued under EPA, Region 10, START-IV Contract
Number EP-S7-13-07.
The specific goals for the West Salem PAs, identified by the EPA, are to:
• Determine the potential threat to public health or the environment posed by
the sites;
• Determine the potential for a release of hazardous constituents into the
environment; and
• Determine the potential for placement of the site on the National Priorities
List (NPL).
Completion of the PAs included reviewing existing site information, collecting
receptor information within the range of site influence, determining regional
characteristics, and conducting a site visit and a limited sampling event. To help
contextualize the facilities under study during this effort, the introductory sections
of this report describe the general/common development and land use in the area
of and surrounding the sites. The following subsections provide details regarding
site-specific features, use history, and similar data for each individual site.

2.2 Site Description
The West Salem PAs site (Figure 2-1) includes several locations that are being
investigated in response to petitions submitted by local residents concerned about
multiple occurrences of osteosarcoma (a rare form of bone cancer) in the West
Salem area of Oregon.
This assessment focused on five different properties in the area: Walker Middle
School, West Salem High School, Wallace Marine Park, Orchard Heights Park,
and the 7th and Patterson Ballfields, and included sampling at a Minto-Brown
Island Park to represent background conditions (Figure 2-2). These properties
were selected for inclusion in the West Salem PAs study during discussions that
took place between the EPA, parents of the children who contracted
osteosarcoma, and other interested parties. Locations selected for this assessment
were identified as places where the children had frequented.
These sites are all located within an approximately 1.75-square-mile area on the
west side of the Willamette River. Three of the properties (Walker Middle
School, Wallace Marine Park, and 7th and Patterson Ballfields) are located at a
lower relative elevation, within the ancestral alluvial flood plain of the Willamette
River. The two remaining sites (West Salem High School and Orchard Heights
Park) are located in upland areas of West Salem. Land use in the vicinity of all of
these sites is a mix of light industrial/commercial and residential, with the light-
industrial/commercial usage typically located in the lower elevation alluvial plain
area.

2. Site Background
The Willamette River is the predominant surface water feature within the study
area, running through Salem and eventually discharging to the Columbia River
approximately 80 miles downstream. Glenn Creek, a small tributary of the
Willamette River, has head waters in the vicinity of West Salem High School, and
from that source runs through various residential neighborhoods, transects
Orchard Heights Park, and discharges to the Willamette River approximately
2.7 miles north of Orchard Heights Park, at a location approximately 3.2 river
miles north of Wallace Marine Park.
2.3 Ownership and Development History
In all but one case, sites included in this project are owned and operated by public
agencies. These include two sites owned by the Salem-Keizer School District
(Walker Middle School and West Salem High School) and two sites owned by the
City of Salem Parks Department (Wallace Marine Park and Orchard Heights
Park). The fifth site is currently owned by KFP Investment LLC (7th and
Patterson Ballfields) (PCA 2012a, 2012b, 2012c, 2013a, 2013b).
2.4 Operations and Waste Characteristics
As discussed above, the sites targeted by this assessment include two public parks
(Wallace Marine and Orchard Heights Parks), two public schools (Walker Middle
and West Salem High Schools), and community used baseball fields located on
privately owned land (7th and Patterson Ballfields). With the exception of the 7th
and Patterson Ballfields property, none of the sites are currently or historically
associated with industrial or commercial operations or ownership. The 7th and
Patterson Ballfields are located on a portion of a parcel that is currently used by a
precision machining business (Hanard Machine) and was historically used by a
textile/manufacturing businesses(Asten-Hill) (EDR2012, 2013a, 2013b, 2013c,
2013d; Carter 2013; PCA 2012a, 2012b, 2012c, 2013a, 2013b). No
industrial/commercial use of the ballfields has been documented.
Based on historic aerial photographs, the park and school properties generally
appear to have been used as agricultural land and/or were residentially occupied
prior to their current uses (EDR 2012, 2013a, 2013b, 2013c, 2013d). Prior to
construction of Walker Middle School, that property appears to have been
developed with athletic fields (SKPS 1959). Aerial photographs depict baseball
fields at their present location on the 7th and Patterson site through at least 1950;
no industrial use, disposal, or storage activities were observed on the ballfields in
these photographs (EDR 2013a).
2.4.1 Geology/Hydrogeology
The Willamette Valley is a structural depression with hills of moderate relief
separating broad alluvial flats. The valley lies between the Cascade Range and
the Coast Range and extends from the Portland Basin southward to a point near
the city of Cottage Grove. The Willamette Valley consists of numerous terraces
and reworked floodplains, primarily of Pleistocene and more recent age.
Regional geology within the alluvial flats consists of a stratigraphic sequence of
largely Quaternary sediments and flow deposits associated with the Willamette

2. Site Background
River and its tributaries. These deposits overlie older parent materials, including
Cascade volcanic rocks and Columbia River Basalts (TechLaw 2011).
Regarding the specific sites included in this assessment, the Walker Middle
School, Wallace Marine Park, 7th and Patterson Ballfields, and background
sampling location (Minto-Brown Island Park, shown on Figure 2-2) are all
situated within the alluvial flats of the Willamette River basin. The remaining
sites (Orchard Heights Park and West Salem High School) are located on uplifted
areas of local basement rock formations (Cascade volcanic rocks and Columbia
River Basalts) (Beja 1981). In general, the sites in the alluvial flats are located at
approximately 120- to 140-feet above sea level, in a topographic regime that
slopes down towards the Willamette River. The Orchard Heights Park and West
Salem High School sites are located approximately 160- to 200-, and 380- to 450-
feet above sea level, respectively (USGS 2011).
In the Willamette Valley, surficial basin deposits include alluvium and flood
deposits often grouped together and commonly referred to as the "over-bank
deposits." Ground water is typically encountered in the "over-bank" units as an
unconfined aquifer (TechLaw 2011). The over-bank deposits consist of
approximately 15 to 20 feet of silt/clayey silt overlying sands, gravels, and some
cemented gravels (Troutdale Formation) to a depth of greater than 100 feet.
Columbia River basalts underlie the Troutdale Formation, and are generally
encountered at 300 to 400 feet below ground surface (bgs) in this area (TechLaw
2011).
2.4.2 Drinking Water Sources
The Oregon Water Resource Department well logs for wells in the area indicate
that the main water-bearing zone for domestic use is from 30 feet to 60 feet bgs,
and the main water-bearing zone for industrial and municipal supply is from 100
feet to greater depths bgs. While non-continuous lenses of silts and clays are
likely present within the sands and gravels and may locally affect the vertical
hydrologic gradient, no significant aquitard or low permeability zone separates
the shallow sands and gravels from the deeper, higher yield gravel zones
(TechLaw 2011).
While some legacy wells are expected to provide drinking water to select
residences in West Salem, the City of Salem provides the vast majority of the
residential drinking water supply. This water is obtained from intakes on the
Santiam River, approximately 19 miles southeast of the site, a location that would
not be influenced by environmental conditions in the West Salem area (Salem
2012).
In accordance with the Safe Drinking Water Act, the City of Salem conducts
ongoing monitoring of drinking water quality. Parameters tested include
inorganic, microbiological, radioactive, and other disinfection (i.e., chlorination)
related constituents. During this testing, the water district collects samples from
the Geren Island Treatment Facility, the water distribution network, and from end

user locations (i.e., taps). According to the 2012 water quality report, none of the
parameters tested for were present at concentrations in excess of the EPA's
published Maximum Contaminant Levels (MCLs) (Salem 2012).
With respect to testing for radioactive constituents, one sample was collected by
the water district from the "backup" drinking water supply well located in the
West Salem area and analyzed for the presence of total radium. Radium levels in
this well were 0.26 picocuries per liter (pCi/L), well below the EPA's MCL of
5 pCi/L. In addition, although this well is a part of the City of Salem's system,
the well is not used since the surface water source provides ample supply (Salem
2012).
2.5 Previous Investigations
In cooperation with the Oregon Health Authority, Dr. Scott Burns at the Geology
Department of Portland State University has lead efforts to compile data on radon
testing conducted in the State of Oregon. This work grouped available radon
testing results by zip code. The potential radon hazard in the zip codes was
evaluated using the maximum test result, average test result, and the percentage of
tests that exceeded 4 pCi/L; these data points were then evaluated by rank sum
distribution analysis which was used to assign radon exposure risk in a given zip
code as a low, moderate, or high potential rating (Burns 2013b). Based on these
evaluations, the short-term test results (i.e., less than 90 days) characterize the
West Salem zip code as having a "high" radon hazard, though the long-term test
results (i.e., 91 days to 1 year) characterize the area as having a moderate radon
hazard (Burns 2013 a). A summary of radon test results for zip codes in the
vicinity of the study area is included as Table 2-1.
During a telephone conversation between the START and Dr. Burns seeking
clarification on the methodology used in evaluating the relative radon exposure
risk, Dr. Burns theorized that the higher levels may relate to exposed areas of
sedimentary rock derived landslide deposits encountered in the West Salem area
(Burns 2013b). Such deposits are located on the south-southwest side of the West
Salem hills (Beja 1981), within unincorporated areas of Polk County zoned for
farm use or low-density (one residence per 5 acre) development (Polk 2008). No
further study of this theory was readily apparent in the literature.
Given the history of these sites, the properties included in this assessment have
not been the target of significant environmental investigatory review in the past.
In preparing this report, the property owners provided available background
documentation on individual sites. To supplement this information, an
environmental database report was generated for each facility. These database
reports included searches of the same databases and target radii as would be used
in an All Appropriate Inquiries/ASTM-1527-05 compliant Phase I Environmental
Site Assessment. In addition, historic aerial photographs and Sanborn Fire
Insurance Maps (as available) were obtained from the database provider. Printed
copies of the historic aerial photographs and maps are included in Appendix B of

included with this report.
More specific information on the environmental databases reports generated and a
review of reports available for each site are included in site-specific sections
presented as Sections 7 through 11 of this report.
2.6 START Site Visit and Community Meetings
Between February 25, 2013 and February 27, 2013, the START and EPA staff
conducted site visits at the Walker Middle School, West Salem High School,
Orchard Heights Park, and 7th and Patterson Ballfields sites included in this PA.
(Note: Wallace Marine Park was later added to the list of PAs based on input
provided by community members at public meetings.) EPA/START staff was
accompanied by property owners/representatives at all but the Orchard Heights
Park site. For information relating to site visits and observations, please refer to
Sections 7 through 11 that follow within this report.
In addition, on the afternoon and evening of February 26, 2013 city, county, state,
and federal governmental parties held two community meetings. These meetings
were meant to provide an opportunity for community members to learn about the
preliminary assessments to provide feedback on the proposed work.
Governmental agency representatives included:
• Anthony Barber, EPA, Director, Oregon Operations Office;
• Joanne LaBaw, EPA, Site Assessment Manager;
• Jae Douglas, Oregon Health Authority, Administrator, Center for Prevention
and Health Promotion;
• Katrina Hedberg, Oregon Health Authority, State Epidemiologist;
• Randy Phillips, Polk County Public Health, Public Health Manager;
• Mike Gotterba, City of Salem, Public Information Officer; and
• Mike Wolf, Salem-Keizer School District, Chief Operations Officer,
Members of the audience included the parents of several children that had
developed osteosarcoma, state and local elected officials, reporters from
Salem/Portland area print and broadcast media, local business owners and
representatives, and concerned citizens.
EPA provided a brief description of the approach to be taken during the EPA's
PAs. In addition, representatives from Oregon Health Authority discussed how
cancer occurrences are tracked by the State of Oregon, and how these data are
used by the State to identify areas where additional epidemiological study may be
warranted. Oregon Public Health officials also answered questions from
community members concerning radon gas levels in the community.

Field Activities and
Analytical Protocol
A Quality Assurance Plan (QAP) for the West Salem PAs was developed by the
START prior to field sampling (E & E 2013). The QAP described the sampling
strategy, sampling methodology, and analytical program to be used to investigate
potential hazardous substance sources and potential targets in the area.
In general, PA field activities were conducted in accordance with the approved
QAP; however, there were several deviations, including: a reduction in the
number of samples collected from the Walker Middle School property; adding
sample collection at the West Salem High School property; and adding more
analytes to the project analytical scope. These deviations are documented in the
Sample Plan Alteration Forms (SPAFs) provided in Appendix C. All deviations
to the SQAP were pre-approved by the EPA Site Assessment Manager during the
field sampling event. The site-specific deviations are explained in the individual
property sections that describe site work.
In addition, based upon comments provided by an environmental advocate
interested in this project, the EPA elected to submit certain samples for analysis of
select total recoverable rare/exotic metals. These constituents included titanium,
zirconium, niobium, tantalum, hafnium, and tungsten. As these analytes are not
typically considered in standard toxicological/risk based assessments, the EPA's
Manchester Environmental Lab (MEL) developed specific methods to test for
their presence and concentration.
The field sampling event for the PAs was conducted from June 10, 2013 through
June 14, 2013. A total of 45 samples, including background samples, were
collected for the PAs. Sample types and methods of collection are described
below. A list of all samples collected for laboratory analysis for the West Salem
PAs is contained in Table 3-1. Chain-of-custody forms, laboratory data sheets of
analytical results, and data validation memoranda for all samples are provided in
Appendix D.
Alphanumeric identification numbers applied by the START to each sample
location (e.g., OHOISS) are used in this report as the sample location identifiers.
Table 3-2 summarizes the sample coding system used for formulating sample
numbers. For example, the sample number OHOISS indicates the following:
• OH for the source code (in this case, Orchard Heights Park);

3. Field Activities and Analytical Protocol
• 01 for the sequential number of samples from a given source area by matrix
(in this case, the first soil sample from Orchard Heights Park); and
• SS for the sample matrix (in this case, surface soil).
This section describes sampling methodology, analytical protocol, global
positioning system (GPS) coordinates, and investigation-derived waste (IDW).
3.1 Sampling Methodology
All PA samples were stored on ice in coolers continuously maintained under the
custody of START personnel. Sampling methods used for each sample type are
described below.
3.1.1 Gamma Field Screening
Field screening was performed at all target properties included in this sampling
event. This screening utilized a Ludlum™ Model 44-2 probe and a Ludlum™
Model 2241-2 rate meter set to relay gamma activity data in kilo-counts per
minute to a Viper data logging system. The Viper system receives simultaneous
inputs from the Ludlum™ meter and a co-located GPS data logger. These
collocated data are then wirelessly transmitted to a field computer that records,
compiles, and uploads the data to project-specific website for data presentation
and visualization (EPA 2013).
The Viper unit, Ludlum™, and GPS link set-up used a wheeled cart for field
screening activities. Screening was performed by walking this cart across select
areas of each site at predetermined transect intervals, ranging from approximately
25 to 50 feet. Prior to performing transects, operational checks were performed
on the Ludlum™ using a Cesium-137 check source. Photographs of a typical
gamma-screening transect and the associated equipment set-up are included in
Appendix A, Sampling Photos 34 and 35.
3.1.2 Soil and Sediment Sampling
Surface soil and sediment were collected from 0 to 6 inches deep using dedicated
stainless steel spoons. Due to the density of the ground surface, several soil
samples required the use of a non-dedicated hand pick to break up the ground
surface prior to sample collection. The hand pick was decontaminated prior to
use and between all subsequent sample locations using distilled de-ionized water
and Alconox. One or more soil samples from each property were collected from
soils underlying the gamma screening transects.
Collected material was placed in a dedicated stainless steel bowl. Grass, leaves,
and other vegetative material, as well as rocks and other debris unsuitable for
analysis, were removed from samples; sediment and other samples with high-
moisture content were decanted, as necessary, then thoroughly homogenized, and
placed into pre-labeled sample containers.

3. Field Activities and Analytical Protocol
3.2 Analytical Protocol
Analytical protocols applied to the PA samples included the following off-site
fixed laboratory analysis (see Table 3-1 for a detailed summary of analyses
applied to individual samples):
• Pesticides/Polychlorinated Biphenyls (PCBs): Thirty-nine samples were
submitted for pesticide and PCB analysis using EPA Method SOM01.2, which
includes analysis by SW-846 8082. The samples were submitted to Shealy
Environmental (Shealy), an EPA Contract Laboratory Program (CLP)
laboratory located in West Columbus, South Carolina.
• Semivolatile Organic Compounds (SVOCs): Thirty-nine samples were
submitted for SVOCs analysis using EPA Method SOM01.2 SIM or SW-846
8270 methodology. All of the samples were submitted to Shealy.
• Target Analyte List (TAL) Metals plus Mercury and Molybdenum:
Thirty-nine samples were submitted for TAL metals analysis using EPA
Method ISM01.2 or SW-846 6000 methodology. All of the samples were
submitted to A4 Scientific, an EPA CLP laboratory, located in The
Woodlands, Texas.
• Gamma Spectrometry with 21-day Ingrowth: Twenty-six samples were
submitted for gamma spectrometry analysis by NAREL-GAM-01
methodology (similar to EPA 901.0). The 21-day ingrowth part of the method
involves sealing the samples tightly for a 21-day period to allow any natural
radon gas to collect and decay through several half-lives (radon-222 gas has a
half-life of 3.8 days), thereby reaching equilibrium with daughter
radionuclides lead-214 and bismuth-214, which can be used to approximate
the radium-226 content of the sample. The method also allows for ingrowth
of actinium-228 from radium-228 so that the actinium-228 activity can be
used to approximate the radium-228 content of the sample. All samples were
submitted to the National Analytical Radiation Environmental Laboratory
(NAREL), located in Montgomery, Alabama.
• Gross Alpha and Beta: Twenty-six samples were submitted to be analyzed
for gross alpha and beta using method NAREL-GR03. All samples were
submitted to NAREL.
• Select Radionuclides (Plutonium, Uranium, Americium, Thorium, and
Strontium): Twenty-six samples were submitted to be analyzed for
individual radionuclides by extraction chromatography. All samples were
submitted to NAREL.
• Rare/Exotic Metals (Tungsten, Titanium, Hafnium, Tantalum,
Zirconium, and Niobium): Twenty-two samples were submitted for analysis
by EPA Method 3050B/200.8/6020 for total recoverable rare/exotic metals.
These samples were sent to the EPA's Manchester Environmental Laboratory
(MEL) located Manchester, Washington. It should be noted that due to the
relatively inert nature of these metals, this data is for recoverable rather than
total metals, and many/most sample results include a low-bias.

3.3 Global Positioning System
GPS coordinates for individual sample points were collected using a Trimble™
Geo XH handheld unit. Recorded GPS coordinates by sample point are listed in
Appendix E. The GPS coordinates obtained in the field for four samples
(WM01SD, OHOISD, OH03SD, and OH05SS) were not sufficiently accurate to
use in mapping. The positions of these samples were estimated from field
knowledge of their locations relative to site features, and the coordinates for these
positions were obtained from GoogleEarth™.
Sample locations for gamma field screening efforts were recorded using the GPS
link of the Viper system. Given the large number of screening locations for
which this screening/Viper data were collected, these locations are not provided in
this report, but rather are graphically displayed on figures included with this
report.
3.4 Investigation-Derived Waste
IDW generated during the sampling effort for the PAs included disposable
personal protective clothing and dedicated sampling equipment. IDW generated
during field activities was rendered unusable by tearing (when appropriate),
bagged in opaque plastic garbage bags, and disposed of at a municipal landfill.
Recyclable field supplies (cardboard, stainless steel bowls, and stainless steel
spoons) were separately bagged and recycled at the EPA's warehouse in Seattle,
Washington.

Quality Assurance/
Quality Control
Quality assurance (QA)/quality control (QC) data are necessary to determine
precision and accuracy and to demonstrate the absence of interferences and/or
contamination of sampling equipment, glassware, and reagents. Specific QC
requirements for laboratory analyses are incorporated in the Contract Laboratory
Program Statement of Work for Organic Analyses (EPA 2007) and the Contract
Laboratory Program Statement of Work for Inorganic Analyses (EPA 201 lb).
These QC requirements or equivalent requirements found in the analytical
methods were followed for analytical work on the project. This section describes
the QA/QC measures taken for the project and provides an evaluation of the
usability of data presented in this report.
Data from the CLP laboratories were reviewed and validated by EPA chemists.
Data from the EPA radiation laboratory were reviewed by EPA personnel at the
laboratory. Data qualifiers and labels were applied, as necessary, according to the
following guidance:
• EPA (2008) USEPA Contract Laboratory Program National Functional
Guidelines for Superfund Organic Methods Data Review;
• EPA (2009) Guidance for Labeling Externally Validated Laboratory Data for
Superfund Use; and
• EPA (2010) USEPA Contract Laboratory Program National Functional
Guidelines for Inorganic Superfund Data Review.
In the absence of other QC guidance, method- and/or SOP-specific QC limits
were also utilized to apply qualifiers to the data.
4.1 Satisfaction of Data Quality Objectives
The following EPA (EPA 2000) guidance document was used to establish data
quality objectives (DQOs) for this project:
• Guidance for the Data (Duality Objectives Process (EPA QA/G-4),
EPA/600/R-96/055.
The EPA Site Assessment Manager determined that definitive data without error
and bias determination would be used for the sampling and analyses conducted
during the field activities. The data quality achieved during the field work
produced sufficient data that met the DQOs stated in the QAP (E & E 2013a). A

4. Quality Assurance/Quality Control
detailed discussion of accomplished project objectives is presented in the
following sections.
4.2 QA/QC Samples
Trip blank QA samples are only required for volatile organic compound (VOC)
analyses and were not collected for this project. Rinsate blank QA samples were
collected for each of the 20 samples using non-dedicated sampling equipment.
QC samples included matrix spike/matrix spike duplicate (MS/MSD) and/or
blank spike (BS) samples at a rate of one MS/MSD and/or BS per 20 samples per
matrix.
4.3 Project-Specific Data Quality Objectives
The laboratory data were reviewed to ensure that DQOs for the project were met.
The following sections describe the laboratories' and/or field team's abilities to
meet project DQOs for precision, accuracy, and completeness, and the field
team's ability to meet project DQOs for representativeness and comparability.
The laboratories and the field team were able to meet DQOs for the project.
4.3.1 Precision
Precision measures the reproducibility of the sampling and analytical
methodology. Laboratory and field precision is defined as the relative percent
difference (RPD) between duplicate sample analyses. The laboratory duplicate
samples or MS/MSD samples measure the precision of the analytical method.
The RPD values were reviewed for all commercial laboratory samples. No
sample results were qualified based on precision outliers; therefore, the project
DQO for precision was met.
4.3.2 Accuracy
Accuracy indicates the conformity of the measurements to fact. Laboratory
accuracy is defined as the surrogate spike percent recovery (%R) or the
MS/MSD/BS %Rs for all laboratory analyses. The surrogate %R values were
reviewed for all appropriate sample analyses. A total of five sample results
(approximately 0.1% of the data) were qualified as estimated quantities (J) based
on surrogate outliers.
The %R values were reviewed for all MS/MSD/BS analyses. A total of 76
sample results (approximately 1.3% of the data) were qualified as estimated
quantities (J) based on MS/MSD/BS outliers; therefore, the project DQO for
accuracy of 90% was met.
4.3.3 Completeness
Data completeness is defined as the percentage of usable data (usable data divided
by the total possible data). All laboratory data were reviewed for data validation
and usability. No sample results were rejected (R); therefore, the project DQO for
completeness of 90% was met.

4.3.4 Representativeness
Data representativeness expresses the degree to which sample data accurately and
precisely represent a characteristic of a population, parameter variations at a
sampling point or environmental condition. The number and selection of samples
were determined in the field to accurately account for site variations and sample
matrices. The DQO for representativeness was met.
4.3.5 Comparability
Comparability is a qualitative parameter expressing the confidence with which
one data set can be compared to another. Data produced for this site followed
applicable field sampling techniques and specific analytical methodology. The
DQO for comparability was met.
4.4 Laboratory QA/QC Parameters
The laboratory data also were reviewed for holding times/temperatures/sample
containers, laboratory blank samples, serial dilution analyses, and rinsate blanks.
These QA/QC parameters are summarized below.
4.4.1 Holding Times/Temperatures/Sample Containers
All holding times, sample temperatures, and containers were acceptable.
4.4.2 Laboratory Blanks
All laboratory blanks met the frequency criteria. The following potential
contaminants of concern were detected in the laboratory blanks:
• Inorganics: Aluminum, antimony, arsenic, beryllium, cadmium, chromium,
lead, molybdenum, mercury, selenium, silver, sodium,
thallium, and vanadium.
See the data validation memoranda for results qualified based on blank
contamination (Appendix D).
4.4.3 Serial Dilution Analyses
Serial dilution analyses met the frequency criteria. A total of 389 sample results
(approximately 6.5% of the data) were qualified based on serial dilution outliers.
4.4.4 Rinsate Blanks
Rinsate blank analyses were performed at a frequency of one per 20 samples
collected using non-dedicated sampling equipment (surface soil samples). There
were no detections in the rinsate blank radiochemical analyses that exceeded the
minimum detectable concentration; therefore, no qualifications were applied to
the associated radiochemical results. Beta-BHC (0.0072 JQ micrograms per liter
[|ag/L]), chromium (0.11 JQ ng/L), and magnesium (0.1 JQ ng/L) were detected
in the rinsate blank. None of these analytes were detected at elevated
concentrations in the surface soil samples; therefore, no qualifications were
applied to these associated sample results.

Analytical Results Reporting
This section describes the reporting methods applied to analytical results
presented in this report.
5.1 Analytical Results Evaluation Criteria
Analytical results presented in the summary tables included at the end of this
report show all analytes detected above laboratory detection limits in bold type.
Analytical results indicating elevated concentrations of contaminants in source
samples and target samples (i.e., surface soil and sediment) with respect to
background concentrations are shown underlined/bold type.
Background concentrations are based on the analysis of samples collected at
Minto-Brown Island Park. Based on its location upriver from both Wallace
Marine Park and current and former industrial facilities, and the absence of
reported industrial use of the park, Minto-Brown Island Park was interpreted to
have a low probability of being influenced or impacted by contaminants that may
be present in the study area. For the purposes of this investigation, elevated
concentrations of inorganic and organic constituents are those concentrations that
are:
• Equal to or greater than the sample's Contract Required Quantitation Limit
(CRQL) or the Sample Quantitation Limit when a non-CLP laboratory was
used; and
• Equal to or greater than the background sample's CRQL or Sample
Quantitation Limit when the background concentration was below detection
limits; or
• At least three times greater than the background concentration when the
background concentration equals or exceeds the detection limits.
For the purposes of this investigation, elevated concentrations of naturally
occurring or otherwise environmentally ubiquitous radionuclides are those
concentrations that are:
• Equal to or greater than the sample's CRQL or, in this case, the laboratory's
Minimum Detectable Concentration; and
• At least two standard deviations above the project-specific mean background
level. To allow for the calculation of mean background levels, four sediment
and soil samples were collected from the background site for radiological
analysis. The mean background activity levels and associated standard

5. Analytical Results Reporting
deviation calculations for each radionuclide are included in Tables 6-3 and
6-6.
The radionuclides detected in samples collected for this report are naturally
occurring, with the exception of cesium-137. Cesium-137 is ubiquitous in the
environment at low levels primarily from man-made sources. It should also be
noted that gross alpha and gross beta are tests that measure general alpha and beta
radiation from any source, both natural and man-made.
It is recognized that the above criteria for determining elevated concentrations of
radionuclides is very conservative. In response to this concern, EPA and START
corresponded with a Health Physicist at the Oregon Health Authority regarding
radiation exposure and dosage risk. This is further discussed in Section 5.2. This
report will focus discussions on the sampling results, with regard to health-based
criteria.
Finally, gamma screening results at each target site were compared to gamma data
obtained during field screening at the background site (Minto-Brown Island Park).
For the purposes of this report, individual screening results (i.e., each gamma
activity count reading) were compared to the mean background gamma activity
level measured in gamma screening transects at Minto-Brown Island Park. Any
single reading at a target location that was greater than two times the mean
background gamma level would have been elevated. It should be noted that the
gamma screening data generated during this assessment is considered provisional,
and was generated with the expressed intent to provide broad level comparison of
the properties under study, rather than form the basis for decisions regarding site
conditions.
The analytical results summary tables provided in this report are a condensed
version of the laboratory data. Data validation memoranda and laboratory data
sheets will be included as Appendix D. The presentation of data in the analytical
summary tables are as follows:
• Analytes that were not present in any sample above their CRQL or minimum
detectable concentration were omitted from their respective tables;
• All detected concentrations are shown in bold type; a non-detect concentration
is shown as the detection limit reported by the laboratory (e.g., 0.66 U);
• The background concentrations and regulatory cleanup levels are provided in
the first columns of the tables;
• Concentrations meeting the elevated definition are underlined.
Based on EPA Region 10 policy, evaluation of aluminum, calcium, iron,
magnesium, potassium, and sodium (i.e., common earth crust metals) is generally
used in mass tracing, which is beyond the scope of this report. Furthermore, these
analytes are not associated with toxicity to humans under normal circumstances
(EPA 1996). For these reasons, these analytes are not included in the evaluation,

but are provided in the analytical summary tables if they were detected above the
instrument detection limit.
5.2 Regulatory Standards
Although not typically part of a PA investigation, soil and sediment sample
results for organic and inorganic constituents in this investigation will be
compared to the Risk Based Concentrations (RBCs) promulgated by the Oregon
Department of Environmental Quality (ODEQ) as a cleanup value for the surface
soil direct contact pathway in a residential scenario. The values presented in
ODEQ's RBC tables have been developed based on contaminated media,
exposure pathway, and receptor scenario.
In the event that an analyte has no available RBC, the sample result was
compared to the EPA Regional Screening Level (RSL) (EPA 201 la). These
screening levels are risk-based concentrations derived from equations combining
exposure information assumptions with EPA toxicity data. They are developed in
accordance with the EPA soil screening guidance and are based on future
residential land use assumptions and related exposure scenarios (EPA 1996).
As ODEQ has not developed RBCs for sediments, the residential soil values were
conservatively applied to these samples for comparison.
Metals and other inorganic elements occur naturally in soil and other matrices,
such as ground water and sediment. The ODEQ has determined that default
background concentrations for inorganic contaminants can be used, at the
discretion of the ODEQ, for sites where site-specific background metals
concentrations are not known. Therefore, the default background concentrations
of certain metals have also been included in summary tables.
Similar to radionuclides, discussion of organic and inorganic constituents within
this report will also be based on a comparison to these RBC or RSL values.
Finally, as no RBCs or RSLs have been developed for radionuclides the START
corresponded with a Health Physicist at the Oregon Health Authority regarding
radiation exposure and dosage risk. Oregon maintains a whole body radiation
dose limit equivalent to 25 millirem (mrem) above background levels (OAR 333-
117-0120).
Additionally, 40 Code of Federal Regulations (CFR) 192 includes soil cleanup
guidance for several radionuclides (radium-226, radium-228, etc.) that specifies a
residual activity from a combination of radium-226 and radium-228 of less than
5 picocuries per gram (pCi/g) for surface soils. That said, the guidance provided
in 40 CFR 192 is not an enforceable statute and was developed to address a very
specific exposure route (i.e., exposure from inhalation of radon decay products
and/or exposure to gamma radiation in houses built on land covered with
radionuclide contaminated tailings from uranium mining sites). For this reason,

this value does not have direct applicability for this PAs evaluation, but may
provide a broad point of comparison for radionuclide results.
Regulatory standards to be applied to soil samples collected for this project are
presented in Table 5-1, as well as included in the first columns of the analytical
summary tables.

6.2 Site Description
Minto-Brown Island Park includes approximately 889 acres of land situated along
the Willamette River at a location that is upstream of the downtown core of
Salem, Oregon and Wallace Marine Park (Figure 2-2). The park includes wooded
and cleared areas transected by paved and unpaved recreational paths, play
equipment, a dog park area, and picnic tables and benches (Figure 6-1). Prior to
its use as a park, the site had been owned by Isaac Brown and John Minto who
raised livestock, farmed, and/or lived on the parkland (Salem 2013a). (Figure 2-
2).
Minto-Brown Island Park was selected as a location that would be representative
of background conditions due to its location upriver from current and former
industrial facilities and Wallace Marine Park, the absence of reported industrial
use of the park, and the low probability of being influenced or impacted by
contaminants that may be present in the study area. Selection of this location as

the representative "background" location had not occurred at the time of the
preliminary site reconnaissance work; therefore, the START did not conduct a site
visit at this property prior to sampling activities.
6.3 Geologic Features
Surficial geology beneath Minto-Brown Island Park site is comprised of recently
deposited river alluvium. The alluvium includes unconsolidated cobbles, coarse
gravel, sand, and some silt and clay. The alluvium is generally 15 to 45 feet thick
and consists of stratified sands and well-rounded pebbles, gravels, and cobbles
(Beja 1981).
6.4 PA Sampling
Soil and sediment samples were collected from two principal locations at the
Minto-Brown Island Park property:
• Soil samples were collected from an upland "farm field" area of the property;
and
• Sediment samples were collected along the Willamette River.
The farm field area was also field screened for gamma radiation using the Viper
system. Figure 6-2 depicts soil and sediment sample locations across the PA
study area. Figure 6-3 depicts soil and sediment sample locations specific to
Minto-Brown Island Park. Figure 6-4 depicts the approximate alignment of
transects with the Viper unit and range of gamma detections. All field work at the
Minto-Brown Island Park site occurred on June 10, 2013.
At the suggestion of NAREL representatives, all four soil and sediment samples
were analyzed for radiological constituent classes (gross alpha, gross beta, gamma
spectrometry, and individual radionuclides). One soil and sediment sample from
Minto-Brown Island Park was submitted for organic and inorganic constituents
analysis (i.e., metals, pesticides, PCBs, SVOCs).
6.4.1 Gamma Radiation Field Screening
Gamma radiation field screening was conducted in a 100-foot by 200-foot area
within a farm field on the property. Screening in this area proceeded on 25-foot
transect intervals with alignment roughly northeast to southwest. Figure 6-4
depicts the transect alignments and corresponding screening results. A summary
of gamma screening readings is included in Table 6-1.
6.4.2 Surface Soil Samples
Four soil samples (BG01SS through BG04SS) were collected from the Minto-
Brown Island Park property to characterize "background" conditions in the PAs
study area (Appendix A, Sampling Photos 1 to 4). These samples were all
collected from within the area of the Viper transects. All four samples were
submitted for analysis of radiological constituents. Sample BG02SS was
submitted for organic and inorganic constituents. The background sample results
are included in the first column(s) of Tables 6-2, 6-3, and 6-4.

7.2 Site Description
The Walker Middle School site includes six tax lots and approximately 15.3 acres
of land that are developed with the middle school buildings, an assortment of
athletic playfields, and vehicular infrastructure including driveways and parking
lots (Figure 7-1). A city-operated swimming pool is also located on the property;
however, the pool has been closed in the recent past as a result of city budget
shortfalls.
Surrounding property is predominantly residential, with single- and multi-family
dwellings constructed north, south, and west of the site. Industrial/commercial
development is located to the east-southeast. The nearest businesses include a
boat storage/repair company, a transmission repair shop, and Hanard Machine
which provides precision machining work (Figure 7-2). An additional machine
shop and a steel sales and processing business are located further to the southeast.
Until the mid- to late-1990s, Gould Battery had been located on the south side of
the steel business (Figure 7-2) (EDR 2012). The Willamette River is located

approximately 0.45 mile south-southeast of the Walker Middle School site
(Figure 7-2).
7.3 Geologic Features
Surficial geology beneath the Walker Middle School site is characterized as high-
terrace deposits that include semi-consolidated light-brown sand, silt, and clay
ranging from 3 to 15 feet thick. These deposits are typical for many terraced
areas adjacent to sedimentary bedrock foothills in the study area. Such bedrock
foothills are present on the northern margin of the site and form much of the
upland area within the West Salem study area. In general, the high-terrace
deposits are mantled by moderately well-drained and well-drained silt loam soils
(Beja 1981).
In 1993, geotechnical investigation work at the site by Foundation Engineering
(FE) included four exploratory boreholes advanced to a maximum depth of 46.5
feet bgs. These boreholes revealed a similar material profile as described above,
with 2 to 4 feet of brown gravelly or rocky silt (interpreted as fill), followed by
approximately 14 feet of grey, very moist, soft silt, with lenses of fine sand.
Below 19 feet bgs, the silt became a saturated, low-density sandy material.
Fractured basaltic bedrock was encountered at between 25 and 29 feet bgs, and
extended to the lowest depths of exploration (FE 1993).
During drilling activities, FE encountered ground water at approximately 15 feet
bgs. As drilling occurred during the dry season, and given observed rust staining
noted at shallower depths, FE anticipated ground water may reach to within
several feet of the ground surfaces during wetter seasons (FE 1993).
7.4 Soil Exposure Pathway
The soil exposure pathway is evaluated based on the threat to residents, nearby
residents, students, and workers from soil contamination within the first 2 feet of
the ground surface and within one mile of the source of contamination.
Approximately 10,972 people reside within one mile of Walker Middle School,
with an additional 951 students attending Walker Middle School or Myers
Elementary School, which are both within the one-mile distance ring.

7. Walker Middle School
Walker Middle School is not used for commercial agriculture or silviculture,
livestock production, or livestock grazing. Further, no terrestrial sensitive
environments occur at the school. The school is accessible and used for
recreation during school hours and during after school programs.
7.5 Surface Water Migration Pathway
As discussed in the previous geologic section, the site is located on a generally
flat alluvial plain; a steep embankment abuts the northern margin of the site, and
is interpreted to locally coincide with the northern limits of the Willamette River's
historic meanders. Surface water runoff on the school grounds is handled by
storm sewer catchments in the paved areas across the site. A small fence-
enclosed, and apparently man-made, wetland is located on the north side of the
property (Figure 7-1). The Willamette River is located approximately 0.5 mile to
the south-southeast.
Surface water runoff is anticipated to be captured by the storm sewer catchments.
For the purposes of this report, runoff from the Walker Middle School site is not
anticipated to provide an overland migratory route from the school to the
Willamette River. The site is located in a Zone X flood area, which is within the
500-year floodplain (FEMA 2003).
The surface water migration pathway target distance limit (TDL) begins at the
probable points of entry of surface water runoff from a site to a surface water
body and extends downstream for 15 miles. As surface water is not anticipated to
reach the Willamette River from the Walker Middle School grounds, no probable
point of entry has been established for this river. With respect to the on-site
wetland, while this may be defined characteristically as a wetland (i.e., saturated
soils, presence of surface water, moisture tolerant vegetation), this wetland is not
included in the National Wetland Inventory. Given the above, targets such as
fisheries and sensitive environmental receptors within the surface water pathway
were not assessed for this property.
7.6 Ownership and Development History
The Walker Middle School property is currently owned by the Salem-Keizer
School District. Other than an appraisal report prepared in 1961 listing Gerald
and Inez Perry as owners of one of the lots that now comprise the Walker Middle
School property, previous ownership information was not available (Geiser 1961).
Based on a review of historic aerial photos, assessor records, and discussions with
site-knowledgeable individuals, the school was first constructed in the late
1950s/early 1960s and underwent a major expansion in the mid-1990s (EDR
2012).
A ground-level photo in a newspaper clipping contained in school district files
depicts the property as vacant land used as a playground, and provides 1961 as the
projected opening time frame for the school (SKPS 1959). Prior to construction
of the school, a 1955 dated aerial photo depicts the school site as a cleared and
predominantly grass covered lot, with an east-west oriented running track visible

on the west side of the property, several smaller access drives on the central and
northwest corner of the site, and several smaller buildings constructed on the site
(EDR 2012). Details regarding construction or use of those smaller structures
were not readily available. An earlier plat map of the site drawn prior to
construction depicted a drainage ditch crossing the site from east to west
(Boatwright 1948).
7.7 Previous Reports
In addition to the environmental database report generated for this facility, the
school district provided limited documentation on the subsurface and
environmental conditions at the property. This information is summarized in the
following sections.
7.7.1 Environmental Database Report
A search of environmental database listings for the site and vicinity revealed
numerous listings, the majority of which are located in the industrial/commercial
area east-southeast of the site. Releases and contamination issues documented in
this area are not considered to represent conditions significantly different than
what may be encountered in most any industrially developed area, generally
consisting of release of various petroleum hydrocarbons, solvents, and heavy
metals. While both Walker Middle School and Hanard Machine were listed in
these database reports, these listings were related to releases discovered during
removal of underground storage tanks (USTs) that had stored petroleum products
(EDR 2012). Further discussion of UST removal activities at the Walker Middle
School property follow within Section 7.7.3 of this report.
As a result of chlorine cylinder leaks at the on-site pool, Walker Middle School
was listed as a "HAZMAT" site. Several properties in nearby residential areas
were also listed, generally in connection with heating oil tank removals (EDR
2012).
Gould Battery/GNB was also listed in the database report in relation to a
petroleum release and a spill of lead oxide. After participating in the Oregon's
Voluntary Cleanup Program and filing an environmental covenant that limits that
site to industrial use, the Gould Battery/GNB site was granted a No Further
Action status by ODEQ (EDR 2012).
7.7.2 Geotechnical Investigation (1993)
In October of 1993, FE presented the Salem-Keizer Public Schools with a
Geotechnical Investigation for the Walker Middle School additions. No
environmental sampling and/or testing occurred in conjunction with this work,
which is discussed in further detail in Section 7.3 (FE 1993).
7.7.3 UST Removal Report (2000)
In December of 2000, Century West Engineering (CWE) oversaw
decommissioning of one 8,000-gallon UST from the Walker Middle School
property that had stored heating oil for use in the school's boiler. Approximately

7. Walker Middle School
100 gallons of product and sludge were removed from the tank prior to removal.
While some pitting and rusting was noted, the removed tank was observed to be
free of holes. Following tank removal, approximately 107 tons of petroleum
stained soil were excavated and stockpiled for characterization. An additional
5 tons of soil were removed from beneath the decommissioned remote fill port.
Remote fill lines were drained, capped, and abandoned in place (CWE 2000).
A total of eight samples were collected during tank decommissioning work.
Confirmation sampling revealed soil conditions at the end of excavation work to
be compliant with ODEQ cleanup standards. The decommissioned tank was
cleaned and sent to Cherry City Metals for recycling; the associated contaminated
soil was transported to United Soil Recycling for thermal desorption treatment,
and the excavation was backfilled with imported clean gravel. Ground water was
not encountered during decommissioning or remedial activities (CWE 2000).
Following decommissioning work, CWE returned to the site to advance five
borings along the abandoned filling line and port alignment to a depth of 8 feet
bgs. Samples were collected from 5 feet bgs in all borings and sent for laboratory
analysis. No petroleum hydrocarbons were detected in any of the samples (CWE
2000).
7.7.4 Radon Sampling
Beginning in 2001, the Salem School District implemented a district-wide radon
screening protocol. This screening involved placing a radon test kit in each
school in the district at locations thought to have the greatest likelihood for the
presence of radon. Following that screening, entire school buildings were then
sampled, focusing first on those structures where radon was detected, and then on
other schools closest to those locations (SKPS 2012). In January of 2013, radon
levels in the Walker Middle School were tested. Testing involved placing a total
of 44 radon test kits in school rooms that were in contact with or below the
ground surface. Radon concentrations were below the detection levels in 30 of
these test kits (i.e., <0.3 pCi/L). The average radon level in 14 kits where
detections occurred was 0.79 pCi/L, with the highest radon level detected in the
school being 1.5 pCi/L. All detected concentrations were below the 4 pCi/L
action level established by the EPA (Ellis 2013a).
7.8 Site Visit Observations
Prior to sampling activities, a site visit was conducted to review conditions at and
surrounding the Walker Middle School property. Participants included:
• Joanne LaBaw, EPA, Site Assessment Manager;
• Derek Pulvino, E & E, Project Manager;
• Jim Jenney, Salem Keizer School District, Interim Director-Facilities and
Planning; and
• David Fridenmaker, Salem Keizer School District, Manager, Planning and
Property Services.

Property conditions noted during the field reconnaissance were considered typical
for public school buildings; concrete block bearing and exterior walls define the
majority of the structure, with a slab-on-grade foundation, a central boiler
supplies hot-water/steam for convective heat, and interior finishes consist of
gypsum board, cellulose ceiling panels, vinyl floor tiles, and carpet. The school
has wood shop and science classrooms. The two laboratory science classrooms
include a front desk/table with running water, natural gas, and non-reactive
countertops. Chemicals are stored in a room located between the two classrooms.
As classes were in session during the original screening review at the site, this
room was not accessed (E & E 2013b).
Exterior areas at the school were primarily grass-covered, with asphalt drives and
parking areas, and landscaping at near-building locations. Select portions of the
property observed during this site visit are included in Appendix A, Site Visit
Photos 1 through 12.
7.9 PA Sampling
Soil and sediment samples were collected from locations distributed across the
Walker Middle School property. Sampling locations were selected to target areas
where it appeared more likely that students or site users would spend time,
focusing on locations where overlying vegetation was either not present or
thinned by occupancy/usage (i.e., baseball infields, walking paths, near benches,
in play areas, etc.). One sediment sample was collected from a fence-enclosed
wetland area on the north-central portion of the property. The athletic fields on
the east and west sides of the school, as well as a small grass covered area north
of the west side of the school building, were field screened for gamma activity
levels using the Viper system. Figure 7-3 depicts soil and sediment sample
locations. Figure 7-4 depicts the approximate alignment of transects with the
Viper unit and range of gamma detections. All field work at the Walker Middle
School site occurred on June 12, 2013.
7.9.1 Gamma Radiation Field Screening
Gamma radiation field screening was conducted at three principal areas on the
Walker Middle School property: the east athletic field; the west athletic field, and
the grass covered area north of the west end of the school building. Screening in
all three areas proceeded on 25 foot transect intervals. Figure 7-4 depicts the
transect alignments and corresponding screening results. A summary of Viper
screening readings from this site is included in Table 6-1.
7.9.2 Surface Soil Samples
Soil samples collected from the Walker Middle School property included five
samples from baseball diamond infield areas (WM01SS, WM02SS, WM03SS,
WM04SS, WM05SS) (Appendix A, Sampling Photos 9 to 13). WM06SS was
collected from the grass area north of the western margin of the school building
(Appendix A, Sampling Photo 15), while WM07SS was collected from an area of
exposed soil near the southern main entrance to the school building.

The QAP called for the collection of up to nine soil samples from this property.
Sample locations were to be selected based on field observations to target areas
with relatively elevated potential for human use that may result in direct contact.
During the field review, exterior areas of the property were observed to be
predominantly grass covered or paved, with broad areas of exposed soils limited
to the baseball diamond infields. Since few other areas of exposed soils were
observed, additional sample collection did not appear warranted.
Sample results are presented in Tables 6-2, 6-3, and 6-4. The detected analytes
were present at concentrations below the RBCs promulgated by ODEQ as a
cleanup value for the surface soil direct contact pathway in a residential scenario
or the applicable naturally occurring concentration.
7.9.3 Sediment Samples
One sediment sample (WM01SD) was collected from the fence-enclosed wetland
area on the north-central portion of the property (Figure 7-3 and Appendix A,
Sampling Photo 14). This sample was collected from the interpreted southwest
margin of the wetland area.
Sample results are presented in Tables 6-5, 6-6, and 6-7. As no human direct
contact RBC has been developed for sediments, the START has conservatively
compared the contaminant concentrations to the ODEQ direct contact RBCs for
surface soil or the applicable naturally occurring concentration. Using this
comparison, the detected analytes were present at concentrations well below the
ODEQ surface soil RBCs for the direct contact pathway in a residential scenario
or the applicable naturally occurring concentration.

8.2 Site Description
The West Salem High School site occupies a single parcel that includes
approximately 54 acres of land. This parcel is developed with the school
building, athletic fields, and other parking- and school-related infrastructure. The
athletic fields extend from the school parcel onto two adjacent lots owned by the
City of Salem Parks Department (PCA 2012c); use of these athletic fields is
shared by the parks department and school district. The school, itself, includes
one interconnected, multi-story building (Figure 8-1).
Surrounding property is residential, predominated by single-family dwellings.
The nearest industrial/commercial land use is approximately 1.25 miles southeast
of the site, in the vicinity of the Walker Middle School and 7th and Patterson
Ballfields sites. At its closest point, the Willamette River is located
approximately 1.6 miles southeast of the West Salem High School site (Figure
2-2).
8.3 Geologic Features
Surficial geology beneath the West Salem High School site is characterized as
Columbia River Basalt. Basalt in the area can range from 400 to 600 feet deep.

8. West Salem High School
Local areas of reddish brown weathered basalt, and can weather into red clay
(laterite) to depths of up to 30 feet (Beja 1981).
In 2000, geotechnical investigation work was performed on the site for design
purposes, included advancing 19 exploratory test pits to between 8 and 20 feet
bgs, and six exploratory borings to between 27 and 41.5 feet bgs. These
explorations revealed a similar material profile as described above, with 2 to over
15 feet of fine-grained, residual soil underlain by highly weathered to
decomposed basalt. Residual soil consists of very stiff to hard, dry to damp silt or
clay, with some scattered fragments of basalt. The bedrock consists of closely
jointed, highly weathered to decomposed extremely weak to weak flood basalt.
Most of the basalt was decomposed to the consistency of medium stiff to hard
soil. Some core-stones were noted and, based on test explorations, appeared to be
discontinuous bodies of strong rock floating in a matrix of decomposed basalt (FE
2000).
No springs, seepage, or ground water were observed within test pits to a
maximum depth of 20 feet. No ground water was detected in piezometers
installed in test borings. Local well logs indicate ground water in the area of West
Salem High School is encountered at approximately 150 to 300 feet of bgs (FE
2000).
8.4 Soil Exposure Pathway
The soil exposure pathway is evaluated based on the threat to residents, nearby
residents, students, and workers from soil contamination within the first 2 feet of
the ground surface and within one mile of the source of contamination.
Approximately 9,743 people reside within one mile of West Salem High School,
and 2,606 students attend West Salem High School, Chapman Hill Elementary,
and Myers Elementary Schools, which are all are present within the one-mile
distance ring. Populations by distance ring within one mile of West Salem High
School are as follows.

8.5 Ownership and Development History
Similar to the Walker Middle School property, the West Salem High School site
is owned by the Salem-Keizer School District. Prior to construction of the school
in 2000, aerial photos depict the property as undeveloped. Fruit orchards were
visible on the site through at least 1954 (EDR 2013b). Assessor records list the
prior usage of the school property as a cherry orchard and for grain cultivation
(PC A 2013c). Prior to school development, other structures noted on the site
were limited to several small buildings located near the east-central margin and
northwest corner of the school/ballfields property. Between 1954 and school
development, the number of fruit trees on the property decreased, with those areas
cleared of fruit trees being grass covered and/or vegetated (EDR 2013b). Sanborn
Fire Insurance Maps did not include coverage of West Salem High School and/or
the property immediately surrounding it.
Appraisal reports covering three of the parcels that were later purchased by the
school district and/or city provide further confirmation of the site's residential
history. These reports list previous owners as follows:
• 2346 Orchard Heights Road: This was a 23-acre area of land developed
with a 1947 vintage, wood-framed residence that was served by an on-site
septic system and drinking water well. Prior owners included H.H and C. A.
Taylor (husband and wife), who purchased the property from Robert and Bette
Worral in May of 1996. Pre-1993 ownership information was not available
(CSP 1999a). By comparing map, text description, and address information
contained in the appraisal report to grading plans provided by the school
district, this property appears to comprise the western side of the school
property. Additionally, the location of some or all of these former buildings
appears to have been in what is now the Titan Drive NW right-of-way.
• Portion of 1655 Doakes Ferry Road NW: While the parcel associated with
this address included 1.5 acres of residentially developed land, this appraisal
report only covered the rear 0.5 acre undeveloped portion of the parcel and did
not include information about the residential development on the other portion
of the parcel. Prior owners were limited to members of the D'Amico family.
Pre-1993 ownership information was not available (CSP 1999b). This
property is situated along the east side of site and is a part of the property
currently owned by the City Parks Department.
• SWC (Southwest Corner) of Orchard Heights & Doakes Ferry Roads
NW: This property included approximately 34.6 acres of undeveloped land.
While properties situated on the east side of this lot were reported to utilize
private septic systems and wells, no such improvements were listed for this
property. Previous owners of this site were detailed to only include Robert
and Floretta Young (CSP 1999c). Review of assessor records list the Young
family to have owned the property as long ago as 1984 (PCA 2013c). This
property makes up most of the east half of the high school site.

8.6 Previous Reports
With the exception of a geotechnical investigation performed for design purposes,
data on subsurface sampling and testing were not available for this property.
Available information on this property is summarized in the following sections.
Applicable details from the geotechnical investigation are included in Section 8.3,
above.
8.6.1 Environmental Database Report
A search of environmental database listings for the site and vicinity revealed that
those listings located within approximately one-half of a mile of the site were
associated with heating oil tank removals. Listings beyond a half-mile are
discussed in further detail in the sections of this report pertaining to Walker
Middle School (see Section 7) and Wallace Marine Park (see Section 9).
8.6.2 Radon Sampling
Beginning in 2001, the Salem School District implemented a radon screening
protocol. This screening involved placing a radon test kit in each school in the
district at a location thought to have the greatest likelihood for the presence of
radon. Following on from that screening, entire school buildings were then
sampled, focusing first on those structures were radon was detected, and then
other schools located nearby (SKPS 2012). In January of 2013, radon levels in
the West Salem High School were tested. Testing involved placing a total of 92
radon test kits in school rooms that were in contact with or below the ground
surface. With two exceptions, radon levels measured in all of the test kits were
less than 2.0 pCi/L; the two exceptions were two lower-level classrooms (Room
B105B at 5.8 pCi/L, and Room B117 at 4.9 pCi/L) (Ellis 2013b).
In response to these results, school maintenance personnel worked to better seal
cracks and trench plates in the floors and adjust the air supply to increase air
circulation in the rooms such that Rooms B105B and B117 are under "positive
pressure." Monitoring data collected immediately after the mitigation efforts
were implemented revealed that radon levels remained above the EPA
recommended 4 pCi/L action level (SKPS 2013a).
Additional steps were then taken to address the continued high levels of radon.
These included additional sealing of the cracks in the floor at one location; after
these additional steps were taken, follow-on testing revealed radon levels of 3.7
pCi/L. At the other location, a sub-slab depressurization mitigation system was
installed; after these additional steps were taken, follow-on testing revealed radon
levels of 0.8 to 1.0 pCi/L. Long-term monitoring of radon levels continues at
these locations (SKPS 2013b).
8.7 Site Visit Observations
Prior to sampling activities, a site visit was conducted to review conditions at and
surrounding the property. Participants included:
• Joanne LaBaw, EPA, Site Assessment Manager;

• Jim Jenney, Salem Keizer School District, Interim Director-Facilities and
Planning; and
• David Fridenmaker, Salem Keizer School District, Manager, Planning and
Property Services.
Property conditions noted during the preliminary field reconnaissance were
considered typical for public school buildings: concrete block bearing and exterior
walls supported with metal columns and trussing define the majority of the
structure, with a slab-on-grade foundation, a central boiler that supplies hot
water/steam for convective and/or forced-air heat, and interior finishes consisting
of gypsum board, cellulose ceiling panels, vinyl floor tiles, and carpet. As per the
current understanding, the school does not include automotive or metal working
spaces. Four laboratory science classrooms were noted, with two on the ground-
floor and two on the second story. These classrooms include lab benches with
running water and natural gas. A utility trench runs through the floor of the two
ground-level laboratory classrooms. Chemicals used in each pair of laboratory
classrooms are stored in a room located between the two classrooms. The
chemicals are segregated on shelving dependent on chemical type (i.e., inorganic,
organic, sulfates, acetates, etc.). The storage rooms also have flammable material
and acid storage cabinets. Evidence of spills or releases was not observed on the
floors in these storage areas.
Exterior areas at the school were primarily grass-covered, with asphalt drives and
parking areas, and landscaping at near-building locations. The site is near the
crest of a hilltop within an area with a locally undulating topography, and the
gradient generally sloping away from the site in all directions. Surface water
drainage in parking areas is predominantly managed by storm water catchment
basins observed in paved areas across the site. A surface water drainage
trench/swale was also observed at the eastern edge of the eastern parking lot,
separating the parking area from the softball/baseball/soccer field complex on the
eastern portion of the site. The trench/swale drains to the south and, apart from
localized area of standing water, was dry at the time of the site reconnaissance
(Figure 8-1). Otherwise, surface water runoff in the area would appear to be
collected by either Glenn Creek, which is located approximately 0.33 mile to the
south, or an unnamed drainage channel mapped to the north of the site that
empties into Glenn Creek. From the confluence of that drainage channel and
Glenn Creek, surface water flows into the Willamette River, which is located
approximately 2.5 miles downstream from the site. As West Salem High School
is located at the crest of a hillside, runoff from this property would only be
expected to reach those drainage channels during heavy rainfall events. A
selection of features observed during the preliminary reconnaissance is included
in Appendix A, Site Visit Photos 13 to 29.

8.8 PA Sampling
Soil samples were collected from locations distributed across the West Salem
High School property. Sampling locations were selected based on the presence of
either exposed soils, and/or target locations where increased exposure risk may be
present from students spending time at a given location. Viper gamma screening
was performed at four principal locations. Figure 8-2 depicts soil sample
locations. Figure 8-3 depicts the approximate alignment of transects with the
Viper unit and range of gamma detections. All field work at the West Salem High
School property occurred on June 14, 2013.
8.8.1 Gamma Radiation Field Screening
Gamma radiation field screening was conducted at four principal areas on the
West Salem High School property: the east athletic field; the south athletic field;
the gravel parking area at the northwest corner of the property; and the small grass
covered area outside the main eastern entrance to the school building. Screening
in all but the grass covered areas proceeded on 50-foot transect intervals aligned
roughly north to south. Transects on the grass covered area east of the school
entrance were spaced approximately 25 feet apart (Figure 8-3).
With respect to the east athletic area, an equipment malfunction prevented the
ability of the Viper system to record data during the first transects. As such, a
second set of transects was conducted in this area. One of the ballfields in this
complex was being used for practice at the time the second set of screening passes
was performed; the START was unable to collect data from this area. Figure 8-3
depicts the transect alignments and corresponding screening results. A summary
of Viper gamma screening results from this site is included in Table 6-1.
8.8.2 Surface Soil Samples
Although the QAP did not include collecting samples from the West Salem High
School property, during the course of the field event, and to help generate
comparable and consistent data for all of the facilities included in the PA, the
START collected three soil samples from this property
The three soil samples collected from the West Salem High School property
included one sample from a landscape planter in the eastern parking lot
(WH01SS), one sample from the grass covered slope leading to the outdoor
assembly area on the west side of the school (WH02SS), and one sample from the
dirt path that leads to the northwest parking lot (WH03SS) (Appendix A,
Sampling Photos 17 to 19).
Sample results are presented in Tables 6-2, 6-3, and 6-4. The detected analytes
were present at concentrations well below the surface soil ODEQ RBCs for the
direct contact pathway in a residential scenario or the applicable naturally
occurring concentration.

9.2 Site Description
The Wallace Marine Park occupies 10 separate tax lots and approximately 101
acres of land along the western bank of the Willamette River. This park includes
a variety of sports fields, open and forested park land, a boat ramp, floating docks,
riverfront beaches, walking trails, picnic areas, and play equipment. Surrounding
property includes what appears to be a gravel mining operation to the north, and a
mix of residential and retail/commercial property to the west. The Willamette
River abuts the southern end and eastern margin of this property (Figure 9-1).
9.3 Geologic Features
Surficial geology beneath the Wallace Marine Park site is a mix of recently
deposited river alluvium and lower terrace deposits of the Willamette River. The
alluvium is located along the river channel and includes unconsolidated cobbles,
coarse gravel, sand, and some silt and clay. The alluvium is generally 15 to 45
feet thick, and consists of stratified sands and well-rounded pebbles, gravels, and
cobbles. Terrace deposits are located on the more inland areas of the site, and are

typically comprised of unconsolidated to semi-consolidated cobbles, gravel, sand,
silt, clay, muck, and organic matter of variable thickness (30 to 50 feet). The
lower terrace deposits are located on the flood plain and lowland terrace area
immediately above the river alluvium. In the case of Wallace Marine Park, these
terrace deposits constitute the upland area of the site, generally from the tree band
along the river inland. A typical profile of lower terrace deposits can include 5 to
20 feet of light-brown silt and clay or very fine sand overlying 10 to 45 feet of
moderately well-sorted sand and locally cemented gravel (Beja 1981).
9.4 Soil Exposure Pathway
The soil exposure pathway is evaluated based on the threat to residents, nearby
residents, students, and workers from soil contamination within the first 2 feet of
the ground surface and within one mile of the source of contamination.
Approximately 13,256 people reside within one mile of Wallace Marine Park,
with 4,725 students attending a university and several public schools within the
one-mile distance ring. Populations by distance ring within one mile of Wallace
Marine Park are as follows.

Wallace Marine Park is not used for commercial agriculture or silviculture,
livestock production, or livestock grazing. Further, no terrestrial sensitive
environments occur at the park. The park is, however, a designated recreation
area.
9.5 Surface Water Migration Pathway
The park is on gently sloping land adjacent to the Willamette River and includes a
small peninsula that extends approximately 0.5 mile into the river. Surface water
runoff can be expected to both infiltrate the ground surface and to flow by sheet
action to the Willamette River throughout the park's frontage with the river.

9. Wallace Marine Park
When evaluating the surface water pathway for a site, EPA considers the target
distance limit, that is, the stretch of a water body that could be impacted by
contamination. The target distance limit begins at the point where site
contaminants may enter the water body, and extends downstream for 15 miles.
When assessing this pathway, the EPA considers the potential for impacts to
drinking water supplies, fisheries, and sensitive environments, such as wetlands
and endangered species, that may be present within the target distance limit.
The 15-mile target distance limit for Wallace Marine Park begins near the
southern margin of the park, at sample WP01SD. This 15-mile target distance
limit is contained wholly within the Willamette River (Figure 9-2).
A search of Oregon Division of Water Resource water rights information query
system for drinking water intakes within the target distance limit revealed that no
such intakes exist, though several intakes exist for irrigation and livestock
watering (ODWR 2013).
The Willamette River is approximately 300 miles in length. Oregon City is
located at approximately river mile 26. The Willamette River is extensively used
for fishing, boating, rafting, and other recreational activities. Sport fish catch for
the river is reported by the Oregon Department of Fish and Wildlife, and is
divided by catch in the table below. The most recent reported fish catch year is
2011. Catch is reported by numbers of individual fish caught. The number of
fish caught is multiplied by the average weight per species to determine the total
pounds of fish catch. Based on these values, it is estimated that the 15-mile target
distance limit spans 5% of the catch area above Oregon City (i.e., 3 001 - 262 =
274; [15 / 274] x 100 = 5%). For this reason, 5% of the total catch above Oregon
City will be attributed as occurring within the 15-mile target distance limit. Sport
catch figures for the target distance limit are provided in the table below.

The Willamette River contains habitat for the federal-threatened steelhead trout
(oncorhynchus mykiss) and Chinook salmon (oncorhynchus tshciwytschci) within
the 15-mile target distance limit (Zawistoski 2013a). Approximately 3.38 miles
of wetland frontage occur on the Willamette River within the target distance limit
with nearest wetland occurring approximately 0.8 mile downstream of the
probable point of entry (Zawistoski 2013a).
9.6 Ownership and Development History
The Wallace Marine Park site is owned by the City of Salem and maintained by
the parks department. Prior to use as a park, historic aerial photos depict the site
as either agricultural, or generally undeveloped, vegetated land between 1954 and
1975 (EDR 2013d). Information provided by the City reports the park was
created after Paul Wallace donated 24 acres of riverfront land to the City.
Development and use as a park began in the late 1950s. Many park features have
been present from the time the park was first developed; however, much of this
infrastructure (roads, boat ramps, and various docks) represents the most recent
"generation" of improvements, as most have suffered periodic damage and have
required rebuilding after local flooding of the Willamette River (Salem 2013b).
Available aerial photographs first show the central baseball/softball field complex
in 1984, when this complex, as well as other roads and parking areas, are
apparently under construction. By 1987, much of the development on the park
was consistent with present day conditions. Sanborn Fire Insurance Maps did not
include coverage of Wallace Marine Park and/or the immediately adjacent area
(EDR 2013d).
9.7 Previous Reports
No previous environmental sampling and testing or review work was readily
available in connection with this property. The results of the environmental
database report generated for this PA are discussed below.
9.7.1 Environmental Database Report
A search of environmental database listings for the site and vicinity revealed
numerous listings in the search radius. In general, the greatest numbers of listings
were located in the industrial/commercial area west-southwest of the site and in
the downtown Salem area, on the opposite side of the Willamette River. No
listings were encountered in connection with the Wallace Marine Park property
(EDR 2013d).

9. Wallace Marine Park
Releases and contamination issues documented in these areas generally include
various petroleum hydrocarbons, solvents, and heavy metals, and are not
considered to represent conditions significantly different than what may be
encountered in most any industrially developed area. Other listings, such as the
Courthouse Athletic Facility, were related to the storage of various chemicals
used during business operations. In the case of Courthouse Athletic Facility, this
included items such as salt (sodium chloride), calcium hypochlorite, carbon
dioxide, hydrochloric acid, etc. (EDR 2013d).
The database report also included a listing for one Comprehensive Environmental
Response, Compensation, and Liability Act of 1980 (CERCLA) No Further
Remedial Action Planned site. That site (Salem Gas Manufacturing) is located on
the opposite side of the Willamette River, approximately 950 feet east of the site,
and is currently a portion of Riverfront Park. Riverfront Park has been the subject
of remedial investigation and feasibility study work. In addition to the
manufactured gas plant, previous uses of the Riverfront Park property include
sawmills, iron works, junkyards, paper manufacturing, and meat packing.
Environmental studies of Riverfront Park have documented impacts to soil,
ground water, and sediments by lead, polycyclic aromatic hydrocarbons (PAHs),
tars, ferrocyanides, benzene, diesel, acids, and caustics. Based on the results of
bioassay testing, impacts to sediments did not appear to be affecting aquatic life.
As part of remedial measures, a deed restriction was placed on the Riverfront Park
parcel, and a soil cap was constructed and is regularly maintained (EDR 2013d,
ODEQ 2013).
9.8 Site Visit Observations
As the Wallace Marine Park property had not been identified for sampling during
original project scoping, the START did not perform a site visit at this property
prior to sampling activities. During sampling activities, observations of
conditions, usage, and development at the Wallace Marine Park site were as
previously discussed in section 9.2.
9.9 PA Sampling
Soil and sediment samples were collected from locations distributed across the
Wallace Marine Park property. Sampling locations were selected based on the
presence of either exposed soils/sediment, the potential for relatively high usage
(e.g., picnic areas), or soils that had a greater potential for mechanical suspension
as airborne dust. In addition, Viper gamma radiation screening was performed at
three areas in the park. Figure 9-3 depicts soil and sediment sample locations.
Figure 9-4 depicts the approximate alignment of transects with the Viper unit and
range of gamma detections. All field work at the Wallace Marine Park property
took place on June 11, 2013. Photographs of sample locations are included as
Appendix A, Sampling Photos 20 to 33.
9.9.1 Gamma Radiation Field Screening
Gamma radiation field screening was conducted at three principal areas on the
Wallace Marine Park property: the southern and northern grass fields; and two of

the baseball diamonds in the baseball/softball complex. Screening in the two
grass fields utilized 25-foot transect spacing aligned roughly north to south.
For the baseball diamonds, during field activities, the START elected to use "ray"
patterns for these transects, with points-of-origin centered on home plate and
radiating to a maximum of 25-foot spacing in the outfield area. Although the
work plan had included Viper gamma radiation screening transects of all five
baseball fields, as tournaments were scheduled to use three fields later in the day,
the park's maintenance personnel requested that field personnel limit occupancy
on those infields. For this reason, Viper gamma radiation screening occurred on
only two ballfields. Figure 9-4 depicts the transect alignments and corresponding
screening results. A summary of Viper gamma radiation screening readings from
this site is included in Table 6-1.
9.9.2 Surface Soil Samples
A total of eight soil samples were collected from the Wallace Marine Park
property. These included the following samples:
• WP01SS and WP08SS: These samples were collected from the soccer fields
in the southern (WP01SS) and northern (WP08SS) grass fields. WP01SS was
collected from soils pushed up within a mole hill. Sample WP08SS was
collected from an area of exposed soil within the eastern soccer goal of the
northern field.
• WP03SS, WP04SS, and WP05SS: Two of these samples (WP03SS and
WP04SS) were collected from beneath the sod along the right (WP03SS) and
left (WP04SS) foul lines for two of the ballfields. The START had planned to
collect these samples from infields; however, due to the aforementioned
tournaments, maintenance personnel requested that field personnel limit
access to, and refrain from diggings holes in, these areas.
At the time of the field work, maintenance personnel also informed the field
personnel that, as a result of flooding that inundated the park in 2012, the
material that been previously been used on the infields of these ballfields had
been removed and replaced with the current material. As the removed infield
material was stockpiled on the site, one additional sample (WP05SS) was
collected from this stockpile.
• WP02SS: This sample was collected from an area of exposed soil near a
lifejacket exchange and instructional sign near the park's boat ramp.
• WP06SS: This sample was collected from soil that had been pushed up in a
mole hill in the picnic area at the southern portion of the park.
• WP07SS: This sample was collected from the crest of the gravel bar east of
the southern picnic area.
Sample results are presented in Tables 6-2, 6-3, and 6-4. The analytes were
detected at concentrations well below the surface soil ODEQ RBC for the direct
contact pathway in a residential scenario or the applicable naturally occurring
concentration.

9.9.3 Sediment Samples
Five sediment samples were collected from the park's Willamette River frontage.
Samples were collected from the sand/silt beach at the southern margin of the
park, near the boat ramp (WP01SD), from a silt/sand beach between the Marion
Street and Center Street Bridges where people's footprints and dog tracks were
noted (WP02SD), and from the southeast corner of the gravel bar located east of
the picnic area (WP03SD). Two additional sediment samples (WP04SD and
WP05SD) were collected north of sample WP03SD. For all of the gravel bar
samples, the matrix included a large percentage of rounded river gravels. In order
to facilitate collection of finer grained and/or organic materials, the fines were
washed and separated from the gravels in the sampling hole, placed in the
homogenizing bowl, and decanted.
Sample results are presented in Tables 6-5, 6-6, and 6-7. As no human direct
contact RBC has been developed for sediments, the START has conservatively
compared the contaminant concentrations to the ODEQ direct contact RBCs for
surface soil or the applicable naturally occurring concentration. Using this
comparison, only the benzo(a)pyrene concentrations detected in sample WP01SD
exceeded the surface soil ODEQ RBCs for the direct contact pathway in a
residential scenario.

10.2 Site Description
Orchard Heights Park is a single parcel that includes approximately 28 acres of
land. Three additional parcels owned by the City of Salem are located along the
southeast border of the site. While it is not apparent whether the three additional
parcels are formerly part of the park, one of these lots was noted to be used as a
public community "pea patch" garden at the time of the original site
reconnaissance. Park development includes tennis and basketball courts, baseball
diamonds, a swing set/play area, various trails and footbridges, and a dog off-
leash area. The park as a whole is a combination of cleared and forested land.
Surrounding property is residential, predominated by single-family dwellings
(Figure 10-1). Historically, much of this developed area appears to have been
agricultural/or chard land. The nearest industrial/commercial land use is
approximately 0.6 mile south-southeast of the site, along the Willamette River,
with the Willamette River located approximately one mile east of the site (Figure
2-2).
10.3 Geologic Features
Surficial geology beneath the Orchard Heights Park site is a mix of lower terrace
deposits of alluvial bottomlands and high-terrace deposits. The lower terrace

deposits are situated at lower elevations within the park, located along the Glenn
Creek alignment. These deposits are generally located in flat, moderately to
poorly drained areas with soft, organic compressible soils, and typically coincide
with areas of low relief, surface water ponding, and high ground water. The
lower terrace deposits typically consist of somewhat stratified very fine sands,
silty sandy clays, silty clays, and silty clay loams, with slight to moderate
plasticity. These deposits can be 4 to 12 feet thick along in the bottomlands of
interior drainages within low, rolling, sedimentary bedrock units, such as found at
the Orchard Heights Park site (Beja 1981).
With respect to the high terrace deposits, these are located at higher elevations
within the park, upgradient from the lower terrace bottomlands deposits, and
include semi-consolidated light-brown sand, silt, and clay ranging from 3 to 15
feet thick. These deposits are typically located in terraced areas adjacent to
sedimentary bedrock foothills. In general, the high-terrace deposits are mantled
by moderately well-drained and well-drained silt loam soils (Beja 1981).
10.4 Soil Exposure Pathway
The soil exposure pathway is evaluated based on the threat to residents, nearby
residents, students, and workers from soil contamination within the first 2 feet of
the ground surface and within one mile of the source of contamination.
Approximately 11,476 people reside within one mile of Orchard Heights Park,
and 1,268 students attend three schools within one mile of the site. Populations

Orchard Heights Park is not used for commercial agriculture or silviculture,
livestock production, or livestock grazing. Further, no terrestrial sensitive
environments occur at the park. The park is a designated recreation area.
10.5 Surface Water Migration Pathway
Glenn Creek transects the site on a north-south alignment. A plastic drainage
conduit discharges to Glenn Creek; however, the source of water flowing from the
conduit was not apparent. Surface water drainage in parking areas is managed by
storm sewer catchment basins observed in the paved areas. Other noted drainage

features include a catchment basin at the northwest corner of the baseball
diamond area and smaller hand-dug ditches along the uphill edges of several
trails. Other than runoff captured by the parking lot and ballfield catchment
basins, surface water runoff would be expected to discharge to Glenn Creek via
sheet flow. Based upon geographic information system (GIS) information
provided by the City of Salem, storm water captured in nearby residential areas
discharges to Glenn Creek at numerous locations within and upstream of Orchard
Heights Park. Figure 10-2 shows outfalls (mapped by the City) that discharge to
the creek as well as storm water infiltration galleries/ponds in the vicinity of
Orchard Heights Park.
When evaluating the surface water pathway for a site, EPA looks at the target
distance limit, that is, the stretch of a water body that could be impacted by
contamination. The target distance limit begins at the location where site
contamination may enter the water body, and extends downstream for 15 miles.
When assessing this pathway, the EPA considers the potential for impacts to
drinking water supplies, fisheries, and sensitive environments, such as wetlands
and endangered species, which may be present within the target distance limit.
For Orchard Heights Park, the 15-mile target distance limit begins where Glenn
Creek enters the park property, which is taken to represent the probable point of
entry for this site. The target distance limit then continues along Glenn Creek,
flowing north to discharge into the Willamette River approximately 2.7 miles
downstream, and concluding 12.3 miles downstream in the Willamette River
(Figure 10-3).
A search of the Oregon Division of Water Resource water rights information
query system for drinking water intakes within the target distance limit revealed
that no such intakes exist, though several intakes exist for irrigation and livestock
watering (ODWR 2013).
The Willamette River is extensively used for fishing, boating, rafting, and other
recreational activities. Sport fish catch is reported by the Oregon Department of
Fish and Wildlife. These data do not report catch for Glenn Creek. For the
Willamette River, harvest is divided by catch below and above Oregon City. The
most recent reported fish catch year is for 2011. Catch is reported by numbers of
individual fish caught. The number of fish caught is multiplied by the average
weight per species to determine the total pounds of fish catch. Based on these
values, it is estimated that the 15-mile TDL spans 4% of the catch area above
Oregon City (i.e., 3003 - 264 = 274; (12.3 / 274) x 100 = 4%). For this reason, 4%
of the total catch above Oregon City will be attributed as occurring within the 15-
mile target distance limit. Sport catch figures for the target distance limit are
provided in the table below.
3 The Willamette River is approximately 300 miles in length.
4 Oregon City is located at approximately river mile 26.

The Willamette River contains habitat for the federal threatened steelhead trout
(oncorhynchus mykiss) and Chinook salmon (oncorhynchus tshciwytschci) within
the 15-mile target distance limit (Zawistoski 2013a). Approximately 1.59 miles
of wetland frontage occur on Glenn Creek, and additional 3.35 miles of wetland
frontage occur on the Willamette River within the target distance limit. The
nearest wetland to the park is approximately 750 feet downstream of the probable
point of entry to Glenn Creek (Zawistoski 2013d).
10.6 Ownership and Development History
The Orchard Heights Park property was purchased from the Salem-Keizer School
District in 1960 by the City's Parks Department. In 1974, development of the
park began when a multi-use court, gravel paths, and landscaping were added to
the site (PCA2013a, 2013d). Historic aerial photos and assessor records show
these developmental changes. Prior to use as a park, the site appears to have been
an undeveloped and predominantly cleared parcel. In the earliest photo (1954),
the western portion of the site appears to have been used as an orchard. Trees
planted in a grid remained in this same area up until sometime between 1987 and
1994. Sanborn Fire Insurance Maps did not include coverage of Orchard Heights
Park and/or the immediately adjacent area (EDR 2013c).
10.7 Previous Reports
No previous environmental sampling and testing or review work was readily
available in connection with this property. The results of the environmental
database report generated for this report are discussed below.
10.7.1 Environmental Database Report
A search of environmental database listings for the site and vicinity revealed that
those listings located within approximately 0.5 mile of the site were associated

Middle School and 7th and Patterson Ballfields sites.
10.8 Site Visit Observations
Prior to sampling activities, a site visit was conducted of the Orchard Heights
Park property. Participants included:
• Joanne LaBaw, EPA, Site Assessment Manager; and
• Derek Pulvino, E & E, Project Manager.
Current site conditions are generally as described in Section 10.2, with a mixture
of cleared and forested land interspersed with the various athletic fields, trails, and
other recreational areas. A paved driveway and parking lot provide access to the
property from Orchard Heights Road, located along the southern property margin.
Photographs from this reconnaissance are included as Appendix A, Site Visit
Photos 30 to 41.
10.9 PA Sampling
Soil and sediment samples were collected from locations distributed across the
Orchard Heights Park property. Sampling locations were selected based on the
presence of either exposed soils/sediment, potential for relatively high occupancy
(i.e., picnic areas), or soils that had a greater potential for mechanical suspension
as airborne dust. In addition, Viper gamma radiation screening was performed on
a large portion of the cleared area of the park. Figure 10-4 depicts soil and
sediment sample locations. Figure 10-5 depicts the approximate alignment of
transects with the Viper unit and the range of gamma detections. All field work at
the Orchard Heights Park property took place on June 13, 2013.
10.9.1 Gamma Radiation Field Screening
Gamma radiation field screening was conducted at two nearly contiguous areas on
the Orchard Heights Park property: the southern baseball field, and the grass area
north of the parking lot and playground. Screening of both areas proceeded on
approximately 25-foot transect intervals aligned roughly north to south. Figure
10-5 depicts the transect alignments and corresponding screening results. A
summary of Viper gamma radiation field screening readings from this site is
included in Table 6-1.
10.9.2 Surface Soil Samples
A total of five soil samples were collected from the Orchard Heights Park
property. These included two samples from southern athletic field (OH01SS and
OH02SS), one sample from exposed soil near the picnic table west-northwest of
the basketball court on the property (OH03SS), one sample from the grass field

Sample results are presented in Tables 6-2, 6-3, and 6-4. The analytes were
present at concentrations well below the surface soil ODEQ RBCs for the direct
contact pathway in a residential scenario or the applicable naturally occurring
concentration.
10.9.3 Sediment Samples
Three sediment samples were collected from readily accessible areas of Glenn
Creek within Orchard Heights Park. These samples were collected working from
downstream to upstream areas of the creek, and included: sample OHOISD,
collected just north of the elevated wood foot bridge that crosses Glenn Creek;
sample OH02SD, collected from sediment on the bottom and banks of Glenn
Creek at the concrete semi-submerged crossing of Glenn Creek; and sample
OH03SD, collected beneath the Orchard Heights Road bridge, at the point where
Glenn Creek enters the park. These sampling locations are depicted as Appendix
A, Sampling Photos 41 to 43.
Sediment sample results are presented in Tables 6-5, 6-6, and 6-7. As no human
direct contact RBC has been developed for sediments, the START has
conservatively compared the contaminant concentrations to the ODEQ direct
contact RBCs for surface soil, or the applicable naturally occurring concentration.
Using this comparison, five SVOCs [benzo(a)anthracene, benzo(a)pyrene,
benzo(b)fluoranthene, dibenzo(a,h)anthracene, and indeno(l,2,3-cd)pyrene] were
present in sediment samples at concentrations above soil RBCs. Two metals,
cobalt and manganese, were detected at concentrations above the EPA Regional
Screening Level and the applicable naturally occurring concentration
(respectively).

11.2 Site Description
The 7th and Patterson Ballfields site is located on a portion of a single tax parcel
that includes approximately 4.45 acres of land. The ballfields area is on the west
margin of this tax parcel, is enclosed with a fence, and is predominantly covered
with grass. Exposed soils are only present in the infield areas. Nearby land
surrounding the property is used for both residential and industrial purposes, with
single- and multi-family dwellings constructed to the west, and industrial/
commercial development to the immediate north, east, and south. Walker Middle
School is located to the west-northwest. The nearest off-property businesses
include a boat storage/repair company and a transmission repair shop, both to the
north, and a machine shop and a steel sales and processing business to the south.
Until the mid- to late-1990s, Gould Battery had been located on the south side of
the steel business. Hanard Machine facilities are directly east of the ballfields and
on the same tax lot. Hanard Machine provides precision machining work for a
variety of manufacturing uses (Figure 11-1). The Willamette River is located
approximately 0.4 mile south-southeast of the site (Figure 2-2).
As previously discussed, the 7th and Patterson Ballfields are located on property
that has been shared by two light-industrial businesses, including the current
Hanard Machine shop and previous textile manufacturer, Asten-Hill. While the
exact process used during textile manufacturing operations is not known,
materials potentially associated with such operations include asbestos (Stengel

2007) as well as petroleum based lubricants and solvents. Hanard Machine uses
various lubricants and coolants in the machining process. The coolants are
maintained in closed-loop systems, distilled, and then recycled. Approximately
50 pounds of coolant still-sludge is disposed of annually by Hanard Machine
(Carter 2013). Various metals in the form of shavings, cuttings, or other similar
machining remnants are also byproducts of Hanard Machine operations.
11.3 Geologic Features
Surficial geology beneath the 7th and Patterson Ballfields site is characterized as
high-terrace deposits that include semi-consolidated light-brown sand, silt, and
clay ranging from 3 to 15 feet thick. These deposits are typical for many terraced
areas adjacent to sedimentary bedrock foothills in the study area. Such bedrock
foothills are present to the north of the site, beginning at the steep embankment on
the northern side of the boat repair business. In general, the high-terrace deposits
are mantled by moderately well-drained and well-drained silt loam soils (Beja
1981).
11.4 Soil Exposure Pathway
The soil exposure pathway is evaluated based on the threat to residents, nearby
residents, students, and workers from soil contamination within the first 2 feet of
the ground surface and within one mile of the source of contamination.
Approximately 9,226 people reside within one mile of the 7th and Patterson
Ballfields, and 530 students attend Walker Middle School, which is within 0.25
mile of the site. Populations by distance ring within one mile of 7th and Patterson
Ballfields are as follows.

The 7th and Patterson Ballfields site is not used for commercial agriculture or
silviculture, livestock production, or livestock grazing. Further, no terrestrial
sensitive environments occur at the school. The site is a designated recreation
area.
11.5 Ownership and Development History
The 7th and Patterson Ballfields site is owned by KFP Investments LLC.
Although there is no record of prior development in the locations occupied by the
ballfields, the lot as a whole includes three buildings that were constructed
sometime between 1936 and 1950, which currently are owned by Hanard
Machine. Over time, the nearest of these buildings has expanded westward, until
reaching their present extent abutting the eastern edge of the ballfields area. A
1936 dated aerial photo shows the entire Hanard Machine property as cleared and

covered with low-vegetation (Hahn 2012). A 1950 dated aerial photograph
depicts what appears to be a baseball diamond at the location of the current
ballfields and the eastern-most portion of the building that is currently occupied
by Hanard Machine (EDR 2013a).
While Hanard Machine has operated in the West Salem area since the late 1960s,
Hanard Machine did not own or occupy the parcel on which the ballfields are
located until their 1995 acquisition from Asten-Hill (PCA 2012a, 2012e).
According to a representative of Hanard Machine, Asten-Hill, now Asten-
Johnson, had manufactured textile products such as "dryer-sheets" for use by the
pulp/paper production business (E & E 2013b). While the exact process and
materials used at the Salem location is not currently known, based on legal
proceedings against other Asten-Hill dryer-sheet manufacturing locations,
asbestos can be associated with the manufacture of these dryer-sheets (Stengel
2007). Earlier Sanborn Fire Insurance Maps show the property occupied by a
"felt manufacturing" business (1978) and a "flax textile" business (1950) (EDR
2013a). Again, little detail is currently available with regard to the processes
employed, resources used, or potential contaminants that may have been
associated with these earlier businesses.
Hanard Machine facilities directly east of the site and on the same tax parcel
provide high-precision machining work for a variety of clients and operations.
Machining work can include the use of various rare/exotic earth metals, such as
titanium, zirconium, hafnium, silver, tungsten, and others (Hanard 2013).
According to company representatives, machining involves turning, lathing, and
machining of metals delivered to the shop. No foundry, smelting, or other
extractive refining work is performed on site (E & E 2013b).
In response to concerns raised by interested parties, the START reviewed NPL-
related files on the Teledyne Wah Chang Albany (TWCA) facility available from
the Albany Public Library. TWCA has been a client of Hanard Machine since at
least the early 1980s (TWCA 1982). The TWCA facility is located approximately
20 miles south of the 7th and Patterson facility (Figure 2-1). TWCA is a facility
that produces zirconium and is included on the EPA's NPL. Hanard Machine has
performed milling/machining work for TWCA on such zirconium products
(TWCA 1982). To process these zirconium products, TWCA receives zirconium
sands and through a process of chlorination, separation, precipitation, and
reduction, isolates the zirconium to produce high-purity zirconium metal
products. As zirconium sands often include low levels of radionuclides, including
radium 226 and radium 228, those radionuclides are a byproduct of the zirconium
production process, and were among the contaminants of concern in TWCA's
NPL listing. NPL documents describe radium laden sands and waste water
sludges being stockpiled on the TWCA manufacturing property. Off-site disposal
of these materials occurred at the U.S. Ecology Low Level Radioactive Waste
Site in Hanford Reservation, Washington, or the U.S. Ecology facility in
Grandview, Idaho (Parametrix 2008).

11. 7th and Patterson Ballfields
Given that radium is removed from the zirconium source sands fairly early in the
extraction/refining process, the documented disposal of the waste material, that
Hanard Machine's association with TWCA is reportedly limited to machining of
finished items, and that Hanard Machine's occupancy of the ballfields lot did not
occur until 1995, disposal of TWCA associated radium laden waste products at
the Hanard Machine facility or the adjacent ballfields appears extremely unlikely.
11.6 Previous Reports
Previous environmental sampling and testing performed at the Hanard Machine
property has included sampling and testing performed in connection with UST
removal from the site; this report was not reviewed in connection with this PA.
The results of the environmental database report generated for this PA are
discussed below.
11.6.1 Environmental Database Report
A search of environmental database listings for the site and vicinity revealed
numerous listings, the majority of which are located in the industrial/commercial
area east-southeast of the site. Releases and contamination issues documented in
this area are not considered to represent conditions significantly different than
what may be encountered in most any industrially developed area, generally
consisting of releases of various petroleum hydrocarbons, solvents, and heavy
metals. While both Walker Middle School and Hanard Machine were listed in
these databases, these listings were related to releases discovered during removal
of USTs that had stored petroleum products (EDR 2013 a). While the UST
removal efforts at the Hanard Machine site were discussed with the property
owner's representative, copies of the associated removal report(s) were not
provided.
Gould Battery/GNB was also listed in database report in relation to a petroleum
release, and the spill of lead oxide. After participating in the Oregon's Voluntary
Cleanup Program and filing an environmental covenant that limits use of the
Gould Battery/GNB property to industrial purposes, that site was granted a No
Further Action status by ODEQ (EDR 2013a).
Regarding other nearby properties, Walker Middle School was listed as a
"HAZMAT" site in response to a chlorine cylinder leak that had occurred at the
on-site pool. Several other properties in nearby residential areas were also listed,
generally in connection with heating oil tank removals (EDR 2013a).
11.7 Site Visit Observations
Prior to sampling activities, a site visit was conducted at the site. Participants
included:
• Joanne LaBaw, EPA, Site Assessment Manager;
• Derek Pulvino, E & E, Project Manager; and

• Mike Carter, Hanard Machine, General Manager.
At the time of the site reconnaissance, the ballfields were enclosed by a fence,
predominantly covered with grass, and exposed soils were only present in
baseball diamond infield areas. No disturbed vegetation, odors, or other similar
conditions were noted during site review. Surface water catchment basins were
noted along curbs in the adjacent roadways.
Similar to the neighboring Walker Middle School site, the 7th and Patterson
Ballfields property and immediate vicinity is a generally flat alluvial plain; a steep
embankment is located several hundred feet to the north and is interpreted to
locally coincide with the northern limits of the Willamette River's historic
meanders. The Willamette River is located approximately 0.5 mile to the south-
southeast. When necessary, the ballfields are irrigated with City water. No hose
bibs or drinking water fountains were observed. Photos of the 7th and Patterson
Ballfields and surrounding area are included as Appendix A, Site Visit Photos 42
to 52.
11.8 PA Sampling
Soil samples were collected from locations with exposed soils. In addition,
gamma field screening was performed across the ballfields area prior to sample
collection. Figure 7-3 depicts soil sample locations. Figure 7-4 depicts the
approximate alignment of transects with the Viper gamma radiation screening unit
and the range of gamma detections. All field work at the 7th and Patterson
Ballfields property took place on June 12, 2013.
11.8.1 Gamma Radiation Field Screening
Gamma radiation field screening was conducted on the ballfields area on 25-foot
transect intervals aligned roughly north to south. Figure 7-4 depicts the transect
alignments and corresponding screening results. A summary of the Viper gamma
radiation screening readings from this site is included in Table 6-1.
11.8.2 Surface Soil Samples
A total of four soil samples were collected from the property. These included two
samples each from exposed soil on the northern (SP01SS and SP02SS) and
southern (SP03SS and SP04SS) baseball diamond infields.
Sample results are presented in Tables 6-2, 6-3, and 6-4. The analytes were
present at concentrations well below the surface soil ODEQ RBCs for the direct
contact pathway in a residential scenario or the applicable naturally occurring
concentrations.

Summary and Conclusions
The West Salem PAs site focused on five individual properties located within an
approximately 1.75-square-mile area on the west side of the Willamette River, in
Salem, Oregon. This investigation was undertaken in response to petitions
submitted by local residents concerned over multiple occurrences of osteosarcoma
(a rare form of bone cancer) in the West Salem area of Oregon. The specific
properties were selected for inclusion in the West Salem PAs during discussions
that took place between the EPA, parents of the children who had osteosarcoma,
and other interested parties. Locations selected for this assessment were
identified as places where the children had frequented.
One of the sites under review (7th and Patterson Ballfields) is part of a parcel that
is, and has been, owned and occupied by commercial/industrial interests;
however, there is no record of the ballfields area of the property having been used
for commercial purposes such as storage, manufacturing, disposal, etc. The
remaining sites included in the West Salem PAs are currently two parks (Wallace
Marine Park, Orchard Heights Park) and two schools (Walker Middle School and
West Salem High School). Prior to these occupancies, these properties had been
used as orchard/agricultural land and/or residential property (West Salem High
School and Orchard Heights Park), or as athletic fields (Walker Middle School).
Prior to use as a park, Wallace Marine Park was not previously developed.
To help with identifying properties with the potential for environmental
contamination, an environmental database report was generated for each site.
While these reports identified multiple cleanup sites within the database search
radii, the types of contamination and cleanup work performed was similar to what
one would expect to find in most any industrial/commercially developed area
across the country. Two sites under study (Walker Middle School and 7th and
Patterson Ballfields) were both listed in the database report; the listings were
related to removal and cleanup of USTs that had stored petroleum products.
To supplement the background research and documentation, sampling and testing
of sediment and soil was undertaken by the START from June 10, 2013 through
June 14, 2013. A total of 45 samples, including background samples, were
collected for the PAs. At least three samples were collected from each site and
submitted for the analysis of pesticides, PCBs, metals, SVOCs, and radionuclides.
In addition, gamma activity level field screening was performed at each property.

12. Summary and Conclusions
Based on analysis of these samples, with few exceptions, the concentrations iden-
tified in the samples were well below established health-based residential screen-
ing levels. These exceptions included some organic and inorganic constituents
detected in sediment samples.
The organic constituents, or SVOCs, identified above a health-based screening
levels were benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, diben-
zo(a,h)anthracene, and indeno(l,2,3-cd)pyrene. These five SVOCs were present
in the three sediment samples collected from Orchard Heights Park at concentra-
tions in excess of the soil RBC for direct contact in a residential scenario. One
sample (WP01SD) collected from Wallace Marine Park contained benzo(a)pyrene
at a concentration above the residential soil RBC.
In addition, cobalt was detected in the three sediment samples from Orchard
Heights Park at concentrations in excess of the EPA RSL for direct contact with
soil. Manganese was detected in one of the Orchard Heights Park sediment sam-
ples at a concentration above the naturally occurring concentration established by
ODEQ.
The five SVOCs, also referred to as PAHs, can be created by naturally occurring
processes, as well as through the incomplete combustion of organic materials such
coal, oil, gas, or garbage (EPA 2008). PAHs are classified as carcinogens,
exposure to which can result in lung, skin, bladder, liver, and stomach cancer;
however, these cancers typically develop as a result of long-term occupational
exposure (ATSDR 2008). The carcinogenicity of cobalt and manganese, both of
which are naturally occurring metals, has not been established (EPA 2014a,
2014b)
With respect to the detections at Orchard Heights Park, following receipt of
sample results, the START reviewed GIS data obtained from the City of Salem
regarding storm water management systems in the vicinity of the Orchard Heights
Park. Based on this information, surface water runoff captured by the drainage
basins along the roadways from many of the surrounding residential
developments is discharged to Glenn Creek. As a point of reference, four outfalls
are mapped as discharging to Glenn Creek in the first approximately 400 feet after
the creek enters the park.
Finally, it should be emphasized that the above discussion comparing sediment
sample results to RBCs and RSLs developed for direct contact with soil in a
residential scenario likely represents a very conservative comparison. This relates
to the methodology used in developing action levels, which take into account both
the toxicity/carcinogenicity of the substance and the time one may be in contact
with the substance. Higher toxicity values and longer potential exposure times
result in lower cleanup levels. As one may expect, a population spends less time
in a park than at their residence, and less time still in contact with sediments in a
creek or river at the park; therefore, the use of the residential soil cleanup levels
for sediment samples is conservative since sediment exposure times can be
expected to be lower than for soils and these lower exposure times would result in
sediment cleanup values that are higher than soil cleanup values.

12. Summary and Conclusions
Various radiological substances have been detected above the minimum
detectable concentration in samples analyzed during this review. In comparing
these results to analysis of samples collected from the background location, many
results were "elevated," as defined in Section 5 of this report. It is recognized that
this method of determining elevated concentrations of radionuclides represents a
very conservative approach. In response to this concern, EPA and START
consulted with a Health Physicist at the Oregon Health Authority regarding
radiation exposure and dosage risk.
The State of Oregon has established 25 mrem/year above natural background
radiation as the annual health-based ceiling for whole-body radiation dosage.
Exposure to radiation above these levels could result in negative health effects.
To compare data obtained from this sampling, Oregon Health Authority
calculated an inhalation dose based on the soil results for all of the samples. For
example, for West Salem High School, the annual inhalation dose calculated
based on the concentrations of the radionuclides, uranium 238 and thorium 232,
would be 0.008 mrem/yr and 0.050 mrem/yr, respectively, which are dosages well
below the annual exposure limit of 25 mrem/year. Further, even if the most
prevalent natural radionuclide maximums encountered at this same location were
summed, the annual inhalation dose would still be less than 0.1 mrem. The
annual external radiation dose would be even lower than that calculated for the
inhalation dose (OHA 2013).
In summary and given the foregoing, none of the environmental factors measured
were present at concentrations that would be expected to contribute to an
increased risk of osteosarcoma. Further, these assessments did not identify any
sources of contamination that would require further investigation or cleanup by
EPA
