ADDITIONAL SITE INVESTIGATION WITH INITIAL GROUND-WATER MONITORING
Chimacum Confluence, Port Hadlock, Washington
EVREN Northwest, Inc. 1 June 18, 2025
Project No. 1643-22001-03
1.0 Introduction
On behalf of Jefferson County Public Health (JCPH, Client), EVREN Northwest, Inc. (ENW) has prepared
this report documenting Additional Site Investigation and Initial Ground-Water Monitoring performed at
the site located at 890 Old Hadlock Road in Port Hadlock, Washington (subject site - see Figures 1 and 2).
The subject site is a 5.3-acre parcel of land with a history of auto salvage and vehicle storage operations.
Ongoing investigations have been completed in support of JCPH’s acquisition of certain sub-parcels for a
conservation easement (Chimacum Confluence Project). JCPH contracted ENW to fill data gaps from
previous work and expand the environmental assessment onto additional land to be acquired by JCPH.
The work was completed in accordance with ENW’s September 2024 Work Plan Addendum, which was
approved by JCPH in coordination with the Washington Department of Ecology (Ecology) Toxics Cleanup
Program.1
1.1 Background
1.1.1 Historical Site Operations
On-site vehicle wrecking operations at the subject site are reported to have started in the early 1970s.
The property owner, Michael Anderson, operated two businesses, Michael’s Custom Rebuild and Towing,
and Michael’s Hulk Hauling. One of the businesses is located on the subject property and the other is
located a few miles offsite.
1.1.2 Early Environmental Reports/Investigations
On October 4, 2005, Ecology received a complaint from a private individual who witnessed car batteries
and automobile fluids having been buried and disposed of on the subject property.
On November 29, 2005, a representative of JCPH visited the site and reported numerous solid waste
violations, including:
• More than 100 junk vehicles, some stored within 40 feet of Chimacum Creek.
• Improperly stored batteries.
• Exposed engines, transmissions, and various automobile engine parts with heavy petroleum
residue.
• An estimated 800 to 1,000 waste tires.
• Pools of petroleum products and sheens on soil and surface water.
• Open and exposed hazardous material containers (antifreeze bottles, oil cans, 55-gallon drums,
etc.) containing product.
• No secondary containment for a diesel fuel tank.

During a subsequent visit on December 21, 2005, JCPH collected four soil samples and two water samples
from the subject property. Laboratory analysis of three of the soil samples reported diesel-range organics
(DRO) over Ecology’s Model Toxic Control Act (MTCA) soil cleanup level of 2,000 milligrams per kilogram
(mg/Kg) and two of the samples exceeded the MTCA soil cleanup level for gasoline-range organics (GRO)
of 30 mg/Kg. Based on results of JCPH’s investigation, the site was referred to Ecology’s Confirmed and
Suspected Contaminated Site List (CSCSL) and JCPH recommended a Site Hazard Assessment (SHA). An
SHA Worksheet 1 (Summary Score Sheet) was completed 2; however, a comprehensive SHA was deemed
impractical since the property was covered with vehicles.
On April 24, 2009, the U.S. Environmental Protection Agency’s (EPA’s) subcontractor, Ecology and
Environment (EE), collected eight soil samples, a background soil sample, three sediment samples from
Chimacum Creek near the site and two background sediment samples, and one wetland sediment
sample.3 Samples were analyzed for pesticides, polychlorinated biphenyls (PCBs), semi-volatile organic
compounds (SVOCs), volatile organic compounds (VOCs), gasoline-range organics (GRO), diesel-range
organics (DRO), and total metals. Sample results identified DRO at a significant concentration with respect
to the background 4 in one sample collected from beneath a rusted 55-gallon drum (sample AP01SS).
Significant concentrations of SVOCs (bis[2-ethylhexyl]phthalate and butylbenzylphthalate) and ten metals
were also detected. Three VOCs (2-butanone, acetone, and toluene) were detected at elevated
concentrations with respect to background concentrations. Of the VOCs detected, acetone was not
detected in source soil samples, and suggests that acetone is unlikely to be attributed to onsite sources.
Because organic hazardous substance concentrations (SVOCs, VOCs, GRO and DRO) were generally
limited, the Anderson property did not warrant further action by the EPA and Ecology’s Toxic Cleanup
Program was assigned as the overseeing regulatory agency.
1.1.3 Recent Environmental Site Investigations
ENW completed a Phase I Environmental Site Assessment (ESA) for the prospective 2-acre stream buffer
project in June 2022.5 The findings of the ESA below were:
• The Anderson property is listed on Washington Ecology’s CSCSL as Site ID 1559 for historical land
use practices suspected of having impacted the subsurface and/or surface waters in adjoining
Chimacum Creek.
• Previous sampling at the Anderson Property had confirmed the presence of gasoline and diesel in
shallow soils at concentrations exceeding MTCA soil cleanup levels.
Based on these findings, ENW conducted a Focused Site Investigation in February through May of 2023.6
This investigation focused on assessment of the same 2-acre western portion of the Chimacum Crossing
property and found residual-range organics (RRO) along with lower concentrations of polynuclear

aromatic hydrocarbons (PAHs), total arsenic, total chromium, and total lead in surface soil that exceeded
MTCA cleanup levels (CULs). Elevated concentrations of arsenic, barium, cadmium, and lead were also
found in reconnaissance ground water samples collected from the proposed acquisition site in
exceedance of MTCA CULs.
Based on the results of the Focused Site Investigation and recent discussions with Ecology and the JCPH,
the following data gaps and/or proposed additional work were identified:
• The additional area to be acquired by JCPH, located adjacent to the originally assessed 2-acre
area, had the same historical land use, but was not investigated as part of ENW’s Focused Site
Investigation.
• During ENW’s Focused Site Investigation, surface soil was assessed using Incremental Sampling
Methodology (ISM) to assess for the presence or absence of hazardous substance for due
diligence purposes. Only one (1) of six (6) decision units (DUs) were sampled using discrete
sampling methods. Ecology does not allow use of composite samples for comparison to cleanup
levels under MTCA. Since JCPH is interested in pursuing regulatory closure, additional discrete soil
sampling is required for five of the six previous decision units and for the new parcel to be
acquired.
• Due to the presence of total and dissolved metals in shallow ground water at the site, further
assessment of shallow ground water flow direction and seasonal changes in dissolved constituent
concentrations over time will be required for site characterization purposes.
ENW developed a Work Plan, which outlines a scope of work (SOW) to further assess the subject property.
Ecology approved of the Work Plan on September 26, 2024 and JCPH authorized the proposed work on
December 18, 2024.1

2.0 Purpose & Scope of Work
The purpose of this investigation was to further investigate whether residual petroleum, heavy metals,
and other contaminants have adversely impacted soil and shallow ground water table beneath the subject
property, including an expanded area, as described in Section 1.1.3, above. ENW performed the following
SOW for this project during three separate mobilizations:
• Performed a geophysical survey of the newly expanded portion of the site to the south of the
southeast quadrant of the original area assessed in 2023.
• Conducted ISM surface soil sampling within the expanded area.
• Collected three (3) discrete soil samples each from DU01 through DU03, and DU05 through DU07.
• Installed, developed, and sampled three (3) monitoring wells to assess ground water flow
direction and analyte concentration changes, to be monitored quarterly for one (1) year
(subsequent ground-water monitoring reports will be submitted under separate cover).
• Submitted samples to an independent laboratory under chain-of-custody protocols for
appropriate analysis.
• Evaluated analytical results with respect to Washington regulatory standards and Ecology
guidance documents.
• Prepared this report documenting investigative methods, site conditions, and findings.
ADDITIONAL SITE INVESTIGATION WITH INITIAL GROUND-WATER MONITORING
Chimacum Confluence, Port Hadlock, Washington
EVREN Northwest, Inc. 5 June 18, 2025
Project No. 1643-22001-03
3.0 Site Setting
Description and Location. The 5.3-acre property is located south of Port Hadlock on Old Hadlock Road.
Chimacum Creek runs along the western property boundary of the subject property. Over half of the
property is considered to be a wetland and about one-quarter of the property is within a special aquifer
recharge protection area (SARPA). A 1948 two story farmhouse is located in the southeastern corner of
the property. The portion of the Anderson Property subject to this investigation lies south of the residence
beyond a walking path and immediately east of Chimacum Creek. It has a shed, a primitive access road
and several junk vehicles and equipment stored within a grassy sloped area that encroaches onto the
Chimacum Creek flood plain. A seasonal pond occupies the northern third of the proposed site.
Topography. The U.S. Geological Survey (USGS) Townsend South, Washington 7.5-Minute Quadrangle
Topographic Map places the subject property at an elevation of approximately 99 feet above mean sea
level within the Chimacum Valley (Figure 1). The property and upland hills north of Old Hadlock Road slope
gently from the east to the west toward the floodplain and wetlands adjacent to Chimacum Creek. Given
its position and gradual slope regionally, Old Hadlock Road likely diverts surface run on from the
surrounding upland area and does not enter the subject site. Storm water landing on the site is likely to
either infiltrate or discharge via overland flow to Chimacum Creek and associated wetlands.
Geologic Setting. Port Hadlock is located on the northeastern Olympic Peninsula at the southwest end of
Port Townsend Bay, which opens up into the north end of the Puget Sound before it joins the Salish Sea.
The subject site is located approximately 1 mile inland, southwest of Port Townsend Bay. The Olympic
Peninsula and Puget Sound were created by the advance and retreat of the glacial ice sheets advancing
from out of what is now British Columbia. Based on mapping 7 provided by the Washington Department
of Natural Resources, the subject site is identified as recessional outwash (Qgo) of the Vashon Stage of
Fraser Glaciation. These recessional outwash sediments are described as pebble to cobble gravel and
sand, gray to tan in color, and generally unoxidized with little iron staining except in the upper 3 to 4 feet
of the unit. Pebble and gravel clasts are of northern provenance, well rounded, unconsolidated, and planar
to cross-bedded. Thickness of the unit ranges from 5 to 100 feet and lies stratigraphically above the
Vashon till.
Soils in the upper portion of the property near Old Hadlock Road are reported to consist of the San Juan
Series, a gravelly sandy loam forming up to 8 percent slopes, exhibiting slight erosion, and somewhat
excessive drainage. The Semiahmoo muck and Mukilteo peat are mapped in the northwest corner of the
site. The upper portion of the Semiahmoo consists of 10 to 15 inches of black organic rich muck which
overlies mineral soils. The Tisch loam covers the west central portion, and the Wapato loam borders
Chimacum Creek.
Soils encountered during previous site investigations were almost exclusively fine-grained with no greater
than 2 mm diameter in grain size.
Surface Water and Ground Water. The subject site borders the east bank of the Chimacum River, a former
sensitive salmon habitat, which has been adversely impacted by runoff from surrounding dairy production
farms and has been re-engineered straighter than its original native meandering mainstem channel. The

creek flows 3.3 miles north where it enters Port Townsend Bay within Puget Sound. Chimacum Creek is
recharged primarily by surface water from higher elevations and is supplemented by shallow ground
water inflow during the rainy season.
Well logs of water wells drilled in the vicinity of the subject property report static ground water levels
ranging from 7 to 27 feet bgs.8 First water observed in well borings was encountered between 1.5 and 3
feet bgs during this investigation. Based on the results of the 2nd Quarter 2025 ground water monitoring
event, the ground-water flow direction was measured to be to the northwest, consistent with topography
and the location of the Chimacum River, with a hydraulic gradient of 0.013 feet/feet.
4.0 Methods and Procedures
This section describes the methods and procedures used to conduct the SOW. Field activities are
documented in the photographic log, included as Appendix A. Monitoring well logs are included in
Appendix B, Field Data Sampling Sheets (FSDS) are included in Appendix C, a laboratory ISM standard
operating procedure is included in Appendix D, and laboratory analytical reports are included in Appendix
E.
4.1 Field Work Objectives
Field work performed for this project was developed with the following general objectives:
• To perform the work efficiently and cost-effectively, minimizing interference with any site
operations.
• To perform the work in a safe manner for technical personnel and site employees / visitors.
• To document information and data generated in a professional manner that is valid for the
intended use.
Field activities were performed during three separate mobilizations in April 2025.
4.2 Preparation Activities
ENW performed or coordinated the following activities prior to conducting field activities:
Plan Preparation. In-house Sampling and Analysis Plan was prepared for the project, specific to this SOW.
One Call Notification. Prior to any subsurface site work, a call was placed with One Call Utility Notification
Service to identify and locate all public utilities near each of the proposed sampling locations.
Planning. ENW scheduled and coordinated with the Client to begin site work.

4.3 Geophysical Survey
The geophysical survey and interpretation of the geophysical data was performed on April 8, 2025, by
Geopotential, Inc. of Clackamas, Oregon under ENW’s oversight. The survey was performed to screen for
the presence of buried features of potential environmental concern within the expanded area and to clear
sampling and well boring locations of underground utilities.
The survey utilized geophysical instruments to identify subsurface magnetic “anomalies.” Geophysical
anomalies result from contrasts of geophysical signatures of subsurface materials but can also result from
interference with surface and overhead features. Geophysical characteristics result from a variety of
factors (e.g., density, distribution, porosity, fill placement, contrasts in soil composition, intergranular fluid
composition and saturation, contaminant impacts, etc.), as well as buried artifacts, and similar anomalies
may be produced by different sources. Except where investigated by excavation, all anomalies and
interpretations should be considered (somewhat) speculative.
Multiple instrument types were used during the survey to maximize recognition of contrasting subsurface
materials. These included:
Aqua-Tronics Electronic Tracer - electromagnetic sensing equipment designed to identify
subsurface anomalies. In the inductive mode, the equipment is used to sense metallic objects in
the subsurface. A conductive mode allows for tracing electrical conduit and metallic pipelines.
Schonstedt Gradiometer (Magnetometer) – used as a complement to the Aqua-Tronics
instrument, the magnetometer senses horizontal variations in the local magnetic field caused by
buried ferrous metal objects such as underground storage tanks (USTs), drums, pipes, and debris-
filled trenches. (Magnetic surveys can only detect ferrous metal objects. Interference caused by
observed surface metal objects limits the accuracy of the survey. The anomalies produced by
fences, power lines, cars, and buildings can easily mask an anomaly caused by an underground
target.)
4.4 Soil Sampling
For additional soil characterization purposes, soil increments and discrete soil samples were collected by
ENW on April 8 and 9, 2025. A Trimble® Global Positioning System (GPS) unit was utilized by ENW
personnel to record the location coordinates of all soil samples and key site features. Sample locations
are illustrated on Figure 3.
4.4.1 Incremental Soil Sampling
ENW assessed surface soils, using Incremental Sampling Methodology (ISM) developed by the Interstate
Technology Regulatory Council (ITRC). ISM is a structured composite sampling and processing protocol
that provides a reasonably unbiased estimate of the mean contaminant concentration in a volume of soil
targeted for sampling (decision unit, or DU). ISM provides representative samples of each DU by collecting
numerous increments of soil (typically 30 to 100 increments) that are combined, processed, and
subsampled according to specific protocols. ISM sampling has the advantage of reducing heterogeneity in
soil (both micro- and macro-scale) to provide an average concentration within the target sample area.
Sample Locations and Depths. On April 8, 2025, surface soil increments were collected from the
uppermost 0.5 feet of soil within DU07, which encompasses the additional area in the southeast portion
ADDITIONAL SITE INVESTIGATION WITH INITIAL GROUND-WATER MONITORING
Chimacum Confluence, Port Hadlock, Washington
EVREN Northwest, Inc. 8 June 18, 2025
Project No. 1643-22001-03
of the site. DU07, along with previous investigation decision units DU01 through DU06, are illustrated on
Figure 3.
Methods. Samples were collected by dividing the DU into a grid pattern with 50 grids and marking with
flags. Increments of equal mass were collected from the approximate center node of each increment grid
(grid-centered systematic sampling), resulting in collection of 50 soil increments from each DU. Increment
locations were distributed evenly within the DU to ensure that the entire area was equally represented in
the final multi-increment sample.
Soil increments were sampled with a decontaminated stainless-steel hand auger. Wood debris and soil or
mineral fragments were removed from each soil increment prior to combining in the laboratory-provided
1-gallon sample container.
All laboratory subsampling and sample preparations were conducted in accordance with ITRC protocols
(air dried, sieved, subsampled, and composited). An ISM sub-sampling and compositing standard
operating procedure prepared by Friedman & Bruya, Inc. (F&BI) of Seattle, Washington, is included in
Appendix D.
4.4.2 Discrete Soil Sampling
On April 9, 2025, three discrete soil samples were collected from each DU01 through DU03 and DU05
through DU07, in accordance with the work plan. Discrete surface soil samples were collected of any
surficial soils that exhibited evidence of petroleum contamination [i.e., staining, odor and/or elevated
photoionization detector (PID) readings]. In the absence of field evidence of impacts, discrete samples
were collected from locations randomly selected in the field.
At DU06 (stockpiled soil), a discrete soil sample was collected from the top, middle, and bottom portion
of the soil stockpile per state guidance.9
4.5 Monitoring Well Installations and Monitoring
Three (3), 2-inch diameter monitoring wells were installed on April 8, 2025, by Anderson Environmental
Contracting (AEC) of Kelso, Washington under ENW’s oversight, in accordance with the work plan. The
monitoring wells were installed for the purpose of collecting quarterly ground water samples, to assess
ground water flow direction and analyte concentrations, over the period of one (1) year. Well construction
details are recorded on monitoring well logs (Appendix B) and summarized in Table 4-1, below. The
locations of monitoring wells are illustrated on Figure 3.

Table 4-1. Well Construction Details
Well reports were prepared by the driller and submitted to Ecology’s Water Resource Program, as
required by WAC 173-160-141. On April 24, 2025, all monitoring wells were surveyed by a Washington
Professional Surveyor, relative to the horizontal North American Datum of 1983 (NAD83), and vertical
North American Datum of 1988 (NAVD 88).
4.5.1 Monitoring Well Borehole Soil Logging & Screening
During monitoring well borehole advancement, soil cuttings were collected continuously and examined
for soil type and field evidence of impacts. Soil cuttings were described using the Unified Soil Classification
System. Vapor headspace readings were collected using a PID to screen for the presence of VOCs. Field
screening results and soil descriptions were recorded onto boring logs included in Appendix B.
4.5.2 Monitoring Well Development
Monitoring wells were developed on April 9, 2025, no sooner than 24 hours after installation.
Approximately six (6) well volumes were purged during development of each well. All purge water from
well development was transferred into drums at the property pending appropriate disposal.
Measurements gathered during monitoring well development were recorded on FSDS, included as
Appendix C.
4.5.3 Monitoring Well Monitoring
On April 16 and 17, 2025, ENW field staff monitored and sampled site monitoring wells (MW01, MW02,
and MW03), in accordance with the Work Plan.
Ground Water Elevations. Ground water elevations in each monitoring well were measured by first
opening the wells to allow water levels to stabilize to ambient pressure and then measuring depth-to-
water (DTW) levels relative to the top-of-casing (TOC). Depth-to-water measurements were collected
using an electronic water-level indicator to the nearest 0.01 feet. Water-level measurements were
recorded on FSDS (Appendix C). Depth to water measurement were subtracted from relative top-of-
monument elevations to determine ground water elevations.
Ground Water Parameters. Approximately 2 to 3 liters of ground water was pumped from each
monitoring well using a low-flow peristaltic pump and dedicated LDPE tubing to “purge” standing water
from the well and draw in representative ground water. Water quality parameters were monitored by
pumping water through a flow-through cell equipped with a water quality probe. Readings for dissolved

oxygen (DO), pH, temperature, specific conductivity, oxidation-reduction potential (ORP), and turbidity
were recorded every 3 to 5 minutes. All sampling data were recorded on FSDS for each monitoring well
(Appendix C).
Ground Water Sampling. When readings stabilized, ground water samples were collected from clean,
dedicated PE tubing connected to a peristaltic pump set at its lowest setting. The flow rate was minimized
to reduce off-gassing of volatile contaminants during sampling. Ground water samples were collected
directly into laboratory-supplied glass sample containers prepared with appropriate sample preservatives,
uniquely labeled, documented on a chain-of-custody (COC), and placed in a cooler on ice, pending
transport to the laboratory.
All non-disposable sampling tools were decontaminated using a sequential wash of Alconox® solution, tap
water rinse, and a final rinse in deionized water. Fresh nitrile gloves were worn by all personnel during
sampling activities. Purge and decontamination water were contained in drums at the property for future
disposal.
4.6 Laboratory Analysis
All soil and ground water samples were transported to F&BI in Seattle, Washington under COC protocol
for analytical testing. Samples were analyzed according to the analytical plan presented in Table 4-2,

4.7 Cleanup Standards
The State of Washington MTCA Regulations [Washington Administration Code (WAC) Chapter 173-340]
sets numeric CULs for “routine cleanup actions”. “Routine cleanup actions” are defined as those sites
where: 1) cleanup standards for each hazardous substance are obvious and undisputed, allowing for an
adequate margin of safety for protection of human health and the environment; 2) does not require
preparation of an environmental impact statement, and 3) qualifies for an exclusion from conducting a
terrestrial ecological evaluation. CULs are defined as the concentration of a hazardous substance in soil,
water, air, or sediment that is determined to be protective of human health and the environment under
specified exposure conditions. MTCA’s two (2) methods for establishing cleanup levels are briefly
described below.
Method A: Method A provides tables of cleanup levels that are protective of human health for the most
common hazardous substances found in soil and ground water at sites. Note that these levels were
developed by procedures of Method B. The Method A cleanup must meet the concentrations listed in the
Method A table and, if not listed in the table, the concentration standards established under applicable
state or federal laws. If neither the Method A table nor applicable state and federal laws provide an
appropriate cleanup level, then natural background concentration or the practical quantitation limit (PQL)
may be used as the cleanup level. Method A is the simplest, most streamlined approach to cleanup, but
is meant to be applied with sites that have releases of only a few, common, hazardous substances.
Method B: Method B provides cleanup levels using risk assessment equations developed for various
exposure pathways, as well as by using standards specified by applicable state and federal laws. Standard
Method B uses generic default assumptions; Modified Method B uses chemical-specific and/or site-
specific parameters in calculating the cleanup levels. Natural background concentrations and PQLs are
also considered in this method. Method B is considered the universal approach to site closure and is the
method most commonly used.
4.8 Investigation Derived Waste Disposal
Potentially impacted investigation-derived waste (IDW) was generated during well installation. All soil
cuttings were placed in DOT-approved 55-gallon drums. Well development water was also stored in 55-
gallon drums. All containers were properly sealed/covered and labeled. Analytical data from this phase of
investigation will be used to profile the IDW for disposal.
Disposable personal protective clothing and sampling equipment (i.e., dedicated Nitrile gloves, towels)
generated during the investigation was bagged in opaque plastic garbage bags and disposed of as
municipal waste.

5.1 Geophysical Survey
On April 8, 2025, GeoPotential conducted the geophysical survey of DU07 using the electromagnetic
scanner followed by the magnetometer and manual excavation (i.e., shovel) where necessary to further
investigate magnetic anomalies. Fourteen (14) magnetic anomalies (MA01 through MA14) were detected
by the survey at the locations presented on Figure 2.
The survey did not suggest the presence of underground storage tanks, dry wells, or septic systems. A
summary of the findings are presented on Table 5-1 and discussed briefly below.
Table 5-1. Summary of Geophysical Survey Findings
Most magnetic anomalies were caused by surficial or buried metal debris (solid waste) typical of an
automotive junk yard.
Magnetic anomaly MA06 represents multiple zones of electromagnetic signals with a significant amount
of buried degraded car parts, including engine parts. Based on the results of the geophysical survey, a
discrete soil sample (GS04) was collected close to MA06.
5.2 Summary of Samples
In total, ENW collected one (1) ISM surface soil sample, 18 discrete soil samples, and three (3) ground
water samples in general accordance with the approved Work Plan. A summary of soil and ground water
samples is presented in table 5-2, below.

Table 5-2. Summary of Soil and Ground Water Samples
Soil encountered during surface soil sampling was generally moist, dark brown, silty, and highly organic
(with roots and decaying matter), with sand present at some locations. Saturated conditions were
encountered at sample locations GS19 through GS21 within the low-lying area prone to ponding during
the rainy season.
Stockpiled soil (GS16 through GS18) consisted of moist, micaceous brown soil, with small amounts of fine
sand with silt.
The PID did not record any organic volatile vapor [i.e., 0.0 parts per million by volume (ppmv)] during
headspace screening of discrete soil samples. Grab sample GS06 was the only discrete soil sample
exhibiting olfactory and visual evidence of petroleum hydrocarbons (e.g., staining and odor). Sample GS04
was collected near MA06, where significant debris, including car parts, was observed.
5.3 Soil Analytical Results
Analytical results of soil samples, including those collected during ENW’s previous investigation, are
presented in Table 1, behind the Tables tab following the text. Results are screened against Ecology’s
Method A and Method B soil CULs and default background concentrations of metals in Washington state.
Results from this investigation are summarized below. Soil sample locations are shown on the Sample
Location Diagram on Figure 3.
Total Petroleum Hydrocarbons (TPH). Laboratory analysis by method NWTPH-HCID detected the
presence of DRO and RRO in the ISM surface soil sample from DU07 and discrete surface soil samples
GS04 and GS06. None of the remaining samples were suggested to contain TPH above laboratory method
reporting limits (MRLs).
Further quantification of TPH detections by method NWTPH-Dx suggested a maximum aggregate
concentrations of DRO and RRO of 1,800 mg/kg, which is below the MTCA Method A soil CUL of 2,000
mg/Kg.
Volatile Organic Compounds (VOCs). Samples with detections of DRO and RRO were further analyzed for
VOCs by EPA Method 8260D. No analyzed VOCs were detected above their respective MRLs.

Semi-Volatile Organic Compounds (SVOCs). Samples with detections of DRO and RRO were further
analyzed for polychlorinated biphenyls (PCBs) by EPA Method 8082A and polycyclic aromatic
hydrocarbons (PAHs) by EPA Method 8270E.
• PCBs were detected in all three samples at concentrations below its MTCA Method A CUL.
However, the detected concentration in sample GS04 exceeded the MTCA Method B Protective
of Ground Water CUL.
• Several PAH constituents were detected in all three samples at concentrations below their
respective MTCA CULs.
Total Metals. The ISM soil sample collected from DU07, and all discrete soil samples from DU01 through
DU03 and DU05 through DU07 were analyzed for total Priority Pollutant 13 (PP13) metals by EPA Method
6020B. The following is a summary of the results:
• Total Antimony was detected in discrete soil samples GS04 and GS05 at concentrations of 3.4
below the MTCA Method B CUL. Antimony was not detected in remaining samples above the
laboratory MRL.
• Total Arsenic was detected in all soil samples with concentrations in four (4) samples exceeding
the MTCA Method A CUL of 20 mg/Kg. Thirteen (13) sampled locations have total arsenic
concentrations above the published background concentration for Washington soils, suggesting
possible anthropogenic enrichment at these locations.
• Total Beryllium was detected in three (3) discrete soil samples (GS07, GS08, and GW10) at
concentrations below its MTCA Method B CUL. Beryllium was not detected in remaining samples
above the laboratory MRL.
• Total Cadmium was detected in the ISM surface soil sample DU07 and discrete surface soil
samples GS04 and GSS05 collected from DU07, exceeding its MTCA CULs and background levels
for Washington, suggesting possible anthropogenic enrichment at these locations. Cadmium was
not detected in any other samples above its laboratory MRL.
• Total Chromium was detected in all soil samples at concentrations below the MTCA Method A
CUL of 2,000 mg/Kg. Only one soil sample (GS07) marginally exceeded its published background
concentration for the State of Washington.
• Total Copper was detected in all soil samples at concentrations below the MTCA Method B CUL.
• Total Lead was detected in all soil samples with one sample (GS04) exceeding the MTCA Method
A CUL of 250 mg/kg. Lead was detected in the ISM surface soil sample DU07 and discrete surface
soil samples collected from DU07 at concentrations greater than its background concentration for
Washington, suggesting possible anthropogenic enrichment in this area.
o Further Evaluation of Total Lead in Surface Soil. The 20x rule, or the Rule of 20 10, is used
to compare the total concentration of a constituent to its RCRA Toxicity Characteristic
Leaching Procedure (TCLP) toxicity limits. Since the concentration of total lead exceeded
10 The 20x rule is based on the 20:1 ratio of extraction fluid to solid sample used in the TCLP procedure. The rule
states that the concentration of a compound in the extraction fluid will be 20 times less than its original
concentration in the sample.

20 times its toxic characteristic concentration (or 100 mg/Kg), sample GS04 was further
evaluated to determine if the concentration of leachable lead in this ISM sample may be
characteristic based on toxicity. Based on this result of TCLP analysis of this sample, the
concentration of leachable lead is below its toxic characteristic concentration (see Table
2). Therefore, while soils containing lead above its CUL may suggest possible enrichment,
they do not appear to exhibit toxic characteristics of leachability from a hazardous waste
characterization perspective.
• Nickel was present in all soil samples at concentrations below its MTCA Method B CUL; however,
was detected at grab sample locations GS07, GS08 and GS10 at concentrations slightly above its
background concentration for Washington, suggesting possible enrichment at these locations.
• Selenium and compounds was only detected in soil sample GS07 at a concentration of 1.1 mg/kg,
which is below its MTCA Method A and B CULs.
• Silver was detected in soil sample GS04, with a concentration of 2.2 mg/kg, which is below its
MTCA Method B CULs. Silver was not detected in any other samples above its laboratory MRL.
• Zinc was detected in all soil samples at concentrations below its MTCA Method B CUL; however,
was detected at DU07 and grab sample locations GS04 through GS06 collected within DU07 at
concentrations above its background concentration for Washington, suggesting possible
enrichment at these locations.
• Mercury and thallium were not detected in any soil samples above laboratory their respective
laboratory MRLs.

5.4.2 Ground Water Parameters
Prior to sample collection, monitoring wells were purged using dedicated polyethylene tubing and
peristaltic pump. During purging, a Horiba U-50 series water quality instrument and flow cell was used to
collect water quality parameters. Table 3 (behind the Tables tab) presents ground water parameter data
measured at the site.
• pH measurements ranged from 6.31 to 7.07 standard units (S.U.), which are within the typical
range of natural waters in Washington (6 to 9).
• Dissolved oxygen ranged from 0.58 to 0.79 milligrams per Liter (mg/L), suggesting anaerobic
conditions.
• Specific conductivity ranged from 0.486 to 0.958 milliSiemens per centimeter (mS/cm),
suggesting slightly high electrical conductivity.
• ORP is typically measured to determine the oxidizing or reducing potential of ground water with
positive values suggesting oxidizing conditions, and negative values suggesting reducing
conditions. Measured OPR values at MW01 and MW03 were -164 and -70 millivolts (mV),
respectively, suggesting reducing conditions at these locations. The measured ORP value at
MW02 was 3 mV, suggesting slightly oxidizing conditions.
• Turbidity values were relatively low in MW01 and MW02 and much higher in MW03. However, it
should be noted that, due to slow recharge, MW03 was pumped dry during purging and sample
collection occurred the next morning following recharge. The turbidity during sampling was
observed to be much lower than during purging.
5.4.3 Ground Water Analytical Results
The results of laboratory analysis of ground water samples are summarized in Table 4, behind the Tables
tab following text. Results in Table 4 are compared to MTCA Method A or B CULs.
Metals. Samples from all three (3) monitoring wells were analyzed for PP13 metals by EPA 6020B. Of the
detected metals, the following were detected at concentrations exceeding their respective CULs.
• Arsenic was detected in all samples with the detected concentration the MW03 sample marginally
exceeding the MTCA Method A and B CUL.
TPH. Ground water samples collected from MW01 were additionally analyzed for TPH by methods
NWTPH-Gx and NWTPH-Dx.
• DRO was detected in the sample at a concentration of 380 µg/L, below its MTCA CUL. The reported
concentration was flagged by the laboratory as likely the result of organic interference. MTCA
regulations and Ecology guidance 11 allow silica gel cleanup (SGC) of sample extracts be performed
to remove non-hydrocarbon polar organics from the sample. Biodegradation of petroleum via
microbial oxidation plays a major role in production of polar organics in ground water. Because
polar organics are less toxic than petroleum, the proportion of petroleum and non-petroleum
polar organics can provide a more accurate understanding of the toxicity of a weathered ground

water plume. ENW instructed the lab to analyze a split of the samples with SGC and laboratory
analysis reported a concentration of 96 µg/L. Interestingly, this result remained flagged due to
the suggestion of organic concentrations not typical of diesel fuel. Regardless, the detected
concentration is below the MTCA CUL.
• Laboratory analysis did not suggest a detection of GRO at a concentration above the laboratory
MRL.
VOCs and SVOCs. Since DRO was detected in the sample collected from MW01, the sample was further
analyzed for VOCs, PAHs and PCBs. Neither VOCs, PAHs, or PCBs were detected in the sample at
concentrations above their respective laboratory MRLs.
5.5 Quality Control
Data validation check sheets are included with the analytical reports in Appendix E and summarized in
laboratory annotations and quality control notes. A review of the laboratory reports for soil and ground
water samples indicates samples were generally analyzed within appropriate quality assurance/quality
control procedures and specified holding times.
6.0 Conclusions and Recommendations
The findings of this investigation have led ENW to the following conclusions:
The geophysical survey within the expanded area did not suggest evidence of USTs or other buried
features of potential environmental concern. However, various vehicles and automotive components
observed on the property could pose an ongoing potential for leaking fluids and/or hazardous substances
onto unprotected ground surfaces.
Analysis of the incremental sample collected from DU07 did not suggest that surface soil has been grossly
impacted with petroleum hydrocarbons or heavy metals above MTCA Method A or B Cleanup Levels.
However, total arsenic, cadmium, and lead were identified in discrete surface soil samples at
concentrations above their respective MTCA CULs. This, along with the presence of buried solid waste
onsite, suggests surface soils on the site may not qualify as clean fill for the purposes of off-site disposal.
Therefore, preparation of a Contaminated Media Management Plan is recommended to provide guidance
for appropriate future handling and management of onsite soils.
In ground water, only total arsenic in monitoring well MW03 was detected at a concentration slightly
above its MTCA CUL (within 10%). The ground water monitoring event included in this investigation
represents the first quarterly monitoring event. Following the schedule outlined in the Work Plan, three
(3) additional quarters of ground water monitoring events will be conducted to further assess hydraulic
fluctuations in response to seasonal changes and its effect on constituent concentrations over time. These
additional monitoring events will be conducted during the 3rd Quarter 2025, 4th Quarter 2025, and the
1st Quarter 2026.
We recommend this report is kept as part of the permanent property records.

7.0 Limitations
The scope of this report is limited to observations made during on-site work; interviews with
knowledgeable sources; and review of readily available published and unpublished reports and literature.
As a result, these conclusions are based on information supplied by others as well as interpretations by
qualified parties.
The focus of the site closure does not extend to the presence of the following conditions unless they were
the express concerns of contacted personnel, report and literature authors or the work scope.
1. Naturally occurring toxic or hazardous substances in the subsurface soils, geology and water,
2. Toxicity of substances common in current habitable environments, such as stored chemicals,
products, building materials and consumables,
3. Contaminants or contaminant concentrations that are not a concern now but may be under future
regulatory standards,
4. Unpredictable events that may occur after ENW’s site work, such as illegal dumping or accidental
spillage.
There is no practice that is thorough enough to absolutely identify the presence of all hazardous
substances that may be present at a given site. ENW’s investigation has been focused only on the
potential for contamination that was specifically identified in the SOW. Therefore, if contamination other
than that specifically mentioned is present and not identified as part of a limited SOW, ENW’s
environmental investigation shall not be construed as a guaranteed absence of such materials. ENW has
endeavored to collect representative analytical samples for the locations and depths indicated in this
report. However, no sampling program can thoroughly identify all variations in contaminant distribution.
We have performed our services for this project in accordance with our agreement and understanding
with the client. This document and the information contained herein have been prepared solely for the
use of the client.
ENW performed this study under a limited scope of services per our agreement. It is possible, despite the
use of reasonable care and interpretation, that ENW may have failed to identify regulation violations
related to the presence of hazardous substances other than those specifically mentioned at the closure
site. ENW assumes no responsibility for conditions that we did not specifically evaluate or conditions that
were not generally recognized as environmentally unacceptable at the time this report was prepared.

Sample Drying and Sieve Preparation for
Multi Increment Soil Sampling
Friedman & Bruya, Inc.
Standard Operating Procedure
Revision Number 3
May 9, 2023
Approved by
Extraction Manager:
Eric Young
Quality Assurance Manager:
Stephanie Pham
This document may contain confidential and/or proprietary information and disclosure or reproduction of
these materials without written authorization of Friedman and Bruya, Inc. is prohibited.
Document Control
Number: Internal Use
Only
Revision 2, 09/25/19, DCN Internal Use Only sops\methods\Multi Increment Sampling Rev3 1
1.0 SCOPE, APPLICATION, AND SUMMARY
1.1 This Standard Operating Procedure (SOP) is used by Friedman and Bruya, Inc.
(F&BI) to prepare soil and solid samples that require sieve and/or drying prior to
extraction and analysis, including sub samples collected for soil multi increment
sampling.
1.2 Deviation from the procedures outlined in this SOP may sometimes be needed,
due to specific project requirements, or due to laboratory circumstances.
Deviations are documented using the extraction worksheet, analysis logs, and/or
other documents such as the non-conformance report form.
2.0 METHOD BASIS
The following regulatory method serves as the basis for this standard operating
procedure. Adherence to the minimum criteria set forth in this method is a general
data quality objective of this SOP.
2.1 State of Alaska Department of Environmental Conservation, “Draft Guidance on
Multi Increment Soil Sampling”, March 2009.
3.0 DEFINITIONS
3.1 A list of definitions for terms used in this SOP may be found in the F&BI
Quality Assurance Manual, appendix F.
4.0 SAFETY
4.1 The most important safety measure is to handle all samples and equipment in
an appropriate manner to ensure a minimum of personal danger and exposure to
potentially hazardous chemicals.
4.2 When samples are handled, appropriate personal protection equipment (PPE)
should be used. Gloves, lab coat, and goggles are all available for use.
4.3 Glassware can break at any time, so caution needs to be used at all times when
handling it. Cut resistant gloves are available for use.
4.4 MSDSs for all chemicals in the lab are available to all employees. They are
located in the GC room, and all employees are strongly encouraged to read them.
4.5 Analysts are required to complete general safety training prior to performing
any analysis. Details of initial and on-going safety training are provided in the
F&BI Quality Assurance Manual and “Training” SOP.
4.6 If uncertain about the safety of a material or procedure or in the event that a
spill or other potentially hazardous situation arises, notify your supervisor or
any chemist immediately.
Revision 2, 09/25/19, DCN Internal Use Only sops\methods\Multi Increment Sampling Rev3 2
5.0 INTERFERENCES
5.1 Certain sample matrices may not be amenable to sieving, such as peat or
tundra. Alternate sample processing measures would be required for those
media.
6.0 APPARATUS AND EQUIPMENT
6.1 #10 Sieve – particle size <2mm
6.2 Drying Pans (Aluminum or Pyrex)
6.3 Stainless Steel Scoopula
6.4 Analytical Balance
6.5 4 oz. or 8 oz. Glass Jars with Lid
6.6 Steel Baking Sheet or Other Tray
6.7 Stainless Steel Bowl
7.0 REAGENTS AND CHEMICALS
7.1 Methylene Chloride, pesticide grade or better
7.2 Alconox
8.0 SAMPLE HANDLING, PRESERVATION, AND PREPARATION
8.1 Before preparing the samples, double check the sample identification on the
container to that listed on the Chain of Custody. Document that the sample ID
has been checked by initialing the extraction worksheet.
8.1.1 If more than one container exists for the sample, write the corresponding
letter of the container used in the extraction on the extraction paperwork.
8.2 Note any unexpected sample characteristics on the extraction worksheet under
“Observations” heading.
8.3 Sample Moisture Determination Procedure
8.3.1 The analyst will perform the following to determine if the sample will
require a drying procedure. Drying should only be performed if necessary.
8.3.2 Visually inspect the sample to determine if free liquid is present. Samples
containing a visible liquid layer will require drying prior to sieve
Revision 2, 09/25/19, DCN Internal Use Only sops\methods\Multi Increment Sampling Rev3 3
preparation.
8.3.3 For samples that do not contain free liquid but appear moist, a small
amount of sample (~10.0 grams) will be tested in the sieve. The sample will
require the drying procedure if sample fines do not pass through the sieve
screen.
8.4 Sample Drying Procedure
8.4.1 Assign F&B sample ID to a drying pan.
8.4.2 Empty the entire contents of the sample container into the drying pan to a
depth of ½ to 1 inch in thickness.
8.4.3 Place drying pan in fume hood at ambient temperature until processing.
8.4.4 Drying at elevated temperatures, i.e. “baking” is not allowed. Turning the
soil can be used to facilitate the drying process.
8.4.5 Drying is acceptable for less temperature sensitive contaminants such as
metals, PCBs, DRO, RRO, etc. Drying may not be appropriate for some
contaminants, including volatile constituents or PAHs. If samples are
processed for non-appropriate testing, the data will be estimated and
qualified appropriately.
8.5 Sieve Procedure
8.5.1 Wash sieve with warm water and Alconox and allow to dry.
8.5.2 For samples requiring organic analysis, triple rinse sieve screen with
methylene chloride and allow to dry.
8.5.3 Place entire contents of sampling container or drying pan into the sieve.
The minimum amount of sample required for sieve preparation is 30 g.
8.5.4 Shake sieve for 2 minutes.
8.5.5 Remove sample collection tray from sieve and collect the entire contents
into a labeled 4 oz. or 8 oz. glass jar.
8.5.6 When multiple sub samples are sieved, the entire contents of each sieved
sub sample will be poured into a stainless steel bowl, stirred for a minimum
of 30 seconds and collected for sample analysis.
9.0 SAMPLE ANALYSIS
9.1 Wash a steel baking sheet or other tray with warm water and Alconox and allow
to dry.
Revision 2, 09/25/19, DCN Internal Use Only sops\methods\Multi Increment Sampling Rev3 4
9.2 For samples requiring organic analysis, triple rinse the tray with methylene
chloride and allow to dry.
9.3 Pour the entire contents of the sample into the tray to a depth of no more than ½
inch.
9.4 Individual aliquots of sample will be randomly scooped from a minimum of 30
distinctly different areas of the tray and added to the extraction vessel until the
required sample amount is reached.
10.0 QUALITY CONTROL AND CORRECTIVE ACTIONS
General quality control procedures are outlined in the corresponding F&B analytical
method SOPs. F&BI QC procedures are described in sections 12 and 13 of the QA
Manual. If, following corrective actions, quality control results still fail, or if corrective
actions are not possible, then affected results are reported with appropriate qualifying
flags.
The minimum requirements for QC samples analyzed with each preparation batch
(within 24 hours) of up to 20 samples are:
1 sample duplicate
11.0 DATA ARCHIVAL
11.1 The hardcopy of the QA paperwork is filed in the extraction room on the
paperwork desk.
11.2 The extraction paperwork for each project is filed in the downstairs filing
cabinets with the hardcopies of the final reports.
12.0 HAZARDOUS WASTE MANAGEMENT AND POLLUTION PREVENTION
12.1 Hazardous waste managements procedures are found in the F&BI QA Manual
section 10, and the “Disposal” SOP.
12.2 Actions that can result in the reduction or elimination of chemical wastes and
chemical pollutants associated with this SOP are strongly encouraged. Such
actions should be discussed with the Executive Committee for approval prior to
implementation.

The 8260D sample aliquots were taken from four ounce glass jars. The results were
qualified accordingly.
The 8260D calibration standard did not meet the acceptance criteria for several
analytes. The data were flagged accordingly.
Acetone did not meet the acceptance criteria in the 8260D matrix spike samples. The
laboratory control samples met the acceptance criteria, therefore the data were likely
due to sample matrix effect.
Selenium in the 6020B matrix spike and matrix spike duplicate did not meet the
acceptance criteria. The laboratory control sample passed the acceptance criteria,
therefore the results were due to matrix effect.
The 6020B antimony calibration standard exceeded the acceptance criteria for several
samples. The metal was not detected, therefore this did not represent an out of control
condition, and were qualified with a “k” qualifier.

CASE NARRATIVE (continued)
A 6020B internal standard did not meet the acceptance criteria for samples GS13-S
and DU02, GS14-SS-DU02. The samples were diluted and reanalyzed with acceptable
results. Both data sets were reported.
All other quality control requirements were acceptable.

The 8260D calibration standard did not meet the acceptance criteria for several
analytes. The data were flagged accordingly.
Chloroethane exceeded the acceptance criteria in the 8260D matrix spike sample. The
compound was not detected, therefore this did not represent an out of control condition.
Methylene chloride was detected in the 8260D analysis of the method blank. The data
were flagged as due to laboratory contamination.
The 6020B calibration standard exceeded the acceptance criteria for several metals.
The metals were not detected, therefore this did not represent an out of control
condition, and were qualified with a “k” qualifier.
All other quality control requirements were acceptable.

Data Qualifiers & Definitions a - The analyte was detected at a level less than five times the reporting limit. The RPD results may not provide reliable information on the variability of the analysis.
b - The analyte was spiked at a level that was less than five times that present in the sample. Matrix spike recoveries may not be meaningful.
ca - The calibration results for the analyte were outside of acceptance criteria, biased low; or, the calibration results for the analyte were outside of acceptance criteria, biased high, with a detection for the analyte in the sample. The value reported is an estimate.
c - The presence of the analyte may be due to carryover from previous sample injections.
cf - The sample was centrifuged prior to analysis.
d - The sample was diluted. Detection limits were raised and surrogate recoveries may not be meaningful.
dv - Insufficient sample volume was available to achieve normal reporting limits.
f - The sample was laboratory filtered prior to analysis.
fb - The analyte was detected in the method blank.
fc - The analyte is a common laboratory and field contaminant.
hr - The sample and duplicate were reextracted and reanalyzed. RPD results were still outside of control limits. Variability is attributed to sample inhomogeneity.
hs - Headspace was present in the container used for analysis.
ht – The analysis was performed outside the method or client-specified holding time requirement.
ip - Recovery fell outside of control limits due to sample matrix effects.
j - The analyte concentration is reported between the method detection limit and the lowest calibration point. The value reported is an estimate.
J - The internal standard associated with the analyte is out of control limits. The reported concentration is an estimate.
jl - The laboratory control sample(s) percent recovery and/or RPD were out of control limits. The reported concentration should be considered an estimate. js - The surrogate associated with the analyte is out of control limits. The reported concentration should be considered an estimate.
k – The calibration results for the analyte were outside of acceptance criteria, biased high, and the analyte was not detected in the sample.
lc - The presence of the analyte is likely due to laboratory contamination.
L - The reported concentration was generated from a library search.
nm - The analyte was not detected in one or more of the duplicate analyses. Therefore, calculation of the RPD is not applicable.
pc - The sample was received with incorrect preservation or in a container not approved by the method. The value reported should be considered an estimate. ve - The analyte response exceeded the valid instrument calibration range. The value reported is an estimate.
vo - The value reported fell outside the control limits established for this analyte.
x - The sample chromatographic pattern does not resemble the fuel standard used for quantitation.

Data Qualifiers & Definitions a - The analyte was detected at a level less than five times the reporting limit. The RPD results may not provide reliable information on the variability of the analysis.
b - The analyte was spiked at a level that was less than five times that present in the sample. Matrix spike recoveries may not be meaningful.
ca - The calibration results for the analyte were outside of acceptance criteria, biased low; or, the calibration results for the analyte were outside of acceptance criteria, biased high, with a detection for the analyte in the sample. The value reported is an estimate.
c - The presence of the analyte may be due to carryover from previous sample injections.
cf - The sample was centrifuged prior to analysis.
d - The sample was diluted. Detection limits were raised and surrogate recoveries may not be meaningful.
dv - Insufficient sample volume was available to achieve normal reporting limits.
f - The sample was laboratory filtered prior to analysis.
fb - The analyte was detected in the method blank.
fc - The analyte is a common laboratory and field contaminant.
hr - The sample and duplicate were reextracted and reanalyzed. RPD results were still outside of control limits. Variability is attributed to sample inhomogeneity.
hs - Headspace was present in the container used for analysis.
ht – The analysis was performed outside the method or client-specified holding time requirement.
ip - Recovery fell outside of control limits due to sample matrix effects.
j - The analyte concentration is reported between the method detection limit and the lowest calibration point. The value reported is an estimate.
J - The internal standard associated with the analyte is out of control limits. The reported concentration is an estimate.
jl - The laboratory control sample(s) percent recovery and/or RPD were out of control limits. The reported concentration should be considered an estimate. js - The surrogate associated with the analyte is out of control limits. The reported concentration should be considered an estimate.
k – The calibration results for the analyte were outside of acceptance criteria, biased high, and the analyte was not detected in the sample.
lc - The presence of the analyte is likely due to laboratory contamination.
L - The reported concentration was generated from a library search.
nm - The analyte was not detected in one or more of the duplicate analyses. Therefore, calculation of the RPD is not applicable.
pc - The sample was received with incorrect preservation or in a container not approved by the method. The value reported should be considered an estimate. ve - The analyte response exceeded the valid instrument calibration range. The value reported is an estimate.
vo - The value reported fell outside the control limits established for this analyte.
x - The sample chromatographic pattern does not resemble the fuel standard used for quantitation.

CASE NARRATIVE
This case narrative encompasses samples received on April 18, 2025 by Friedman &
Bruya, Inc. from the Evren Northwest 1643-22001-05, F&BI 504306 project. Samples
were logged in under the laboratory ID’s listed below.
Laboratory ID Evren Northwest
504306 -01 MW01-GW-250416
504306 -02 MWFD-GW-250416
504306 -03 MW02-GW-250416
504306 -04 MW03-GW-250417
The 8270E PAH sample was analyzed outside of the holding time. The sample was
kept in refrigeration maintained at 4 degrees Celsius prior to extraction, therefore the
loss of any target compounds would be minimal.
All other quality control requirements were acceptable.

hs - Headspace was present in the container used for analysis.
ht – The analysis was performed outside the method or client-specified holding time requirement.
ip - Recovery fell outside of control limits due to sample matrix effects.
j - The analyte concentration is reported between the method detection limit and the lowest calibration point. The value reported is an estimate.
J - The internal standard associated with the analyte is out of control limits. The reported concentration is an estimate.
jl - The laboratory control sample(s) percent recovery and/or RPD were out of control limits. The reported concentration should be considered an estimate. js - The surrogate associated with the analyte is out of control limits. The reported concentration should be considered an estimate.
k – The calibration results for the analyte were outside of acceptance criteria, biased high, and the analyte was not detected in the sample.
lc - The presence of the analyte is likely due to laboratory contamination.
L - The reported concentration was generated from a library search.
nm - The analyte was not detected in one or more of the duplicate analyses. Therefore, calculation of the RPD is not applicable.
pc - The sample was received with incorrect preservation or in a container not approved by the method. The value reported should be considered an estimate. ve - The analyte response exceeded the valid instrument calibration range. The value reported is an estimate.
vo - The value reported fell outside the control limits established for this analyte.
x - The sample chromatographic pattern does not resemble the fuel standard used for quantitation.
