SUBJECT: April 2007 Soil Assessment,Tigard Library,Tigard, Oregon
l Qui
INTRODUCTION
On April 23 and June 21, 2007, GeoEngineers collected soil samples at the southeast portion of the Tigard
Library property, located at 13500 SW Hall Boulevard, Tigard, Oregon (site). The Oregon Department of
Environmental Quality (DEQ) Environmental Cleanup Site Information (ECSI) site identification number is
4063.
Soil samples were collected on April 23, 2007 to refine the understanding of the extent of arsenic in soil in
areas scheduled to be disturbed during planned road construction and stream/wetland restoration activities at
the site. The June 21, 2007 soil samples were collected to assess subsurface soil quality in areas where
stream/wetland restoration was planned. The site layout and sampling locations are shown on Figure 1. The
sampling events were conducted at the request of Ms. Vannie Nguyen of the City of Tigard and in accordance
with City of Tigard Work Orders No. 2 and No. 3 —Agreement No. 0560002.
FIELD ACTIVITIES
April 2007
GeoEngineers collected soil samples from eight locations near the south side of the site during the April 2007
sampling event. GeoEngineers also collected a three point composite sample for waste profiling purposes.
Soil samples were collected from surface (0-1 foot) and subsurface (2-3 feet) intervals at the eight locations
(HA-1 through HA-8) shown on Figure 1. The composite sample was collected from three locations (14A-9A,
HA-9B, and HA-9C) in the interval between 1 and 2 feet below ground surface (bgs). The composite sample
was collected in the vicinity of a retention pond at the southwest portion of the site, in the area where the
highest concentrations of arsenic were previously detected.
The soil samples were collected using a stainless steel hand auger that was decontaminated between each
boring using an Alconox wash and a double rinse with tap water and distilled water. Samples were collected
from the hand auger using new disposable nitrile gloves and placed directly into laboratory-provided sample
containers. GeoEngineers recorded the location of each hand auger boring using a sub-meter grade global
positioning system (GPS) instrument that was differentially corrected.
June 2007
GeoEngineers collected subsurface soil samples from eight locations (SP-1 through SP-8) in planned
stream/wetland restoration areas during the June 2007 sampling event. Soil samples were collected from
target surface for the restored stream/wetland bottom and two feet below the target surface. The elevation of
the target surface was determined based on stream/wetland restoration plans provided by the City of Tigard

and a TopCon0 surveying instrument. The depth to the target surface varied between approximately 2 and 5-
feet below the pre-construction ground surface.
The June 2007 soil samples were collected from test pits that were excavated with a tracked excavator,
operated by Landis and Landis, Inc., a City of Tigard contractor. Soil samples were collected from the center
of the excavator bucket using new disposable nitrile gloves and immediately placed in laboratory-provided
sample containers. GeoEngineers recorded the horizontal location of each test pit using a sub-meter grade
global positioning system (GPS) instrument that was differentially corrected.
SOIL CHEMICAL DATA
The April 2007 soil samples were submitted to TestAmerica laboratory in Beaverton, Oregon for analysis of
arsenic by U.S. Environmental Protection Agency (EPA) Method 6020. The waste profiling composite
sample was submitted for analyses of leachable arsenic using EPA Methods 1311/601 OB. The June 2007 soil
samples were submitted to Apex Labs in Tigard, Oregon for expedited analysis of arsenic by EPA Method
6020. Chemical analytical data are summarized in Table 1 and laboratory reports are included in
Attachment A.
April 2007 Sample Chemical Data
Arsenic was detected in eight soil samples collected from five borings at concentrations (7.22 to 20.4
milligrams per kilogram [mg/kg]) above the DEQ default background concentration (7 mg/kg). The highest
concentrations of arsenic were detected in soil collected from boring HA-1, at the southwest side of the site.
Arsenic was not detected in samples collected at the far southeast portion of the site (HA-7 and HA-8).
Leachable arsenic was not detected in the waste profiling sample. Figure I shows sample locations.
GeoEngineers reviewed all data quality exceptions documented by the accredited laboratory. No significant
data quality exceptions were noted by the laboratory.
The April 2007 chemical analytical data indicate that arsenic is present at concentrations exceeding the DEQ
default background concentration in soil between the surface and approximately 3 feet bgs in much of the
planned stream/wetland restoration area. Figure 1 shows the approximate extent of soil that contains arsenic
at concentrations exceeding the DEQ default background concentration. Soil that contains concentrations of
arsenic above 7 mg/kg should be considered contaminated and should be managed in accordance with
GeoEngineers' April 11, 2007 Contaminated Soil Management Plan, Tigard Library, Tigard, Oregon.
June 2007 Sample Chemical Data
Arsenic was detected in six soil samples collected from eight test pits at concentrations (7.96 to 21.1 mg/kg)
above the DEQ default background concentration. The highest concentrations of arsenic were detected in
soil collected from test pit SP-1, at the west side of the site, near the April 2007 hand auger sample HA-1. No
significant data quality exceptions were noted by the laboratory.
The June 2007 sample analytical data indicate that arsenic in soil exceeds the default background
concentration at the target depths in several areas of the planned stream/wetland restoration area. Arsenic
concentrations generally decrease to levels that are less than or only slightly exceed the default background
concentration approximately 2 feet below the target depths.

SUMMARY AND CONCLUSIONS
Arsenic was detected in soil at concentrations exceeding the DEQ default background concentration in nine
locations. The highest concentrations of arsenic were detected near the southwest corner of the site, in the
vicinity of an outfall for Pinebrook Stream. Arsenic concentrations varied between approximately 2.43 and
21.1 mg/kg. The highest concentrations of arsenic were detected in soil collected between the ground surface
and approximately 3.5 feet bgs. Below 3.5 feet bgs, arsenic was no detected at a concentration exceeding
8.49 mg/kg.
The data collected in April and June 2007 indicate that portions of the planned stream/wetland restoration
area are located within soil that contains concentrations of arsenic that exceed the DEQ default background
concentration. The data also indicate that the highest concentrations of arsenic are present in soil between the
surface and approximately 3.5 feet bgs.
Soil that contains arsenic at concentrations exceeding 7 mg/kg should be considered contaminated and should
be managed in accordance with GeoEngineers' April 11, 2007 Contaminated Soil Management Plan, Tigard
Library, Tigard, Oregon. Leachable arsenic was not detected in the composite waste profiling sample,
indicating that the contaminated site soil will be accepted at a Subtitle D landfill, such as Waste
Management's Hillsboro Landfill.
Samples collected at target depths for the stream/wetland restoration indicate that some soil in that area
contains concentrations of arsenic that exceed the default background concentration. GeoEngineers will
coordinate with the City of Tigard and DEQ regarding short term management of soil during stream/wetland
restoration activities and to implement a permanent remedy for the site.

Report Specific Notes:
M2 - The MS and/or MSD were below the acceptance limits due to sample matrix interference. See Blank Spike(LCS).
R3 - The RPD exceeded the acceptance limit due to sample matrix effects.
R4 - Due to the low levels of analyte in the sample,the duplicate RPD calculation does not provide useful information.
Laboratory Reporting Conventions:
DET - Analyte DETECTED at or above the Reporting Limit. Qualitative Analyses only.
ND - Analyte NOT DETECTED at or above the reporting limit(MDL or MRL,as appropriate).
NR/NA - Not Reported/Not Available
dry - Sample results reported on a Dry Weight Basis. Results and Reporting Limits have been corrected for Percent Dry Weight.
wet Sample results and reporting limits reported on a Wet Weight Basis(as received). Results with neither wet'nor'dry'are reported
on a Wet Weight Basis.
RPD - RELATIVE PERCENT DIFFERENCE (RPDs calculated using Results,not Percent Recoveries).
MRL - METHOD REPORTING LIMIT. Reporting Level at,or above,the lowest level standard of the Calibration Table.
MDL* - METHOD DETECTION LIMIT. Reporting Level at,or above,the statistically derived limit based on 40CFR,Part 136,Appendix B.
*MDLs are listed on the report only if the data has been evaluated below the MRL. Results between the MDL and MRL are reported
as Estimated Results.
Dil - Dilutions are calculated based on deviations from the standard dilution performed for an analysis,and may not represent the dilution
found on the analytical raw data.
Reporting - Reporting limits(MDLs and MRI-s)are adjusted based on variations in sample preparation amounts,analytical dilutions and
Limits percent solids,where applicable.
Electronic -, Electronic Signature added in accordance with TestAmerica's Electronic Reporting and Electronic Signatures Policy.
Signature Application of electronic signature indicates that the report has been reviewed and approved for release by the laboratory.
Electronic signature is intended to be the legally binding equivalent of a traditionally handwritten signature.
