RE: State Painting Analytical Results Report

Dear Mr. Dunham:

Enclosed for your review is the Analytical Results Report (ARR) for State Painting (SEMS
ID# UTN000820797), located in West Valley City, Salt Lake County, Utah. The ARR focuses on
sampling performed on the West Valley City wetlands property (herein referred to as the “Site”),
located west and north-adjacent to the State Painting property.

A Removal Action was conducted by the U.S. Environmental Protection Agency (EPA)
Emergency Removal Branch in May 2018 at the State Painting residential property located at
6594 Parkway Boulevard, West Valley City, Salt Lake County Utah. Removal activities included
collecting surface water and sediment samples from a stormwater retention pond at the Site.
Analytical results for metals in the surface water were as high as 757 micrograms per liter (µg/L)
for total arsenic and 764 µg/L for dissolved arsenic. Samples collected from sediment were as high
as 76.3 milligrams per kilogram (mg/kg). The Division of Environmental Response and
Remediation (DERR) developed a Site Inspection Work Plan in 2023 to evaluate unknowns
concerning potential off-Site contributors to contamination, the extent of arsenic contamination, and
the risk of exposure to human and environmental health.

Results from the DERR sampling in August 2023 indicate elevated arsenic concentrations
in surface water from two locations in the stormwater retention pond; one with concentrations of
390 g/L and 370 g/L for total and dissolved arsenic, respectively, and the other with
concentrations of 470 g/L and 450 g/L, respectively. The dissolved concentrations exceed the
Utah Standards of Quality for Waters criteria for aquatic wildlife for both acute (340 g/L; 1-hour
average) and chronic (150 g/L; 4-day average) parameters, and are significantly higher than the
Page 2
background concentration of 13 g/L. The corresponding arsenic concentrations in the sediment
were 44 and 43 mg/kg, which exceeds the Los Alamos National Laboratory Low Effect Ecological
Screening Level of 33 mg/kg for aquatic community organisms, and significantly exceeds the
background concentration of 5.8 mg/kg. Additional surface water and sediment samples from the
same locations were analyzed for inorganic arsenic, and the data indicates the presence of mainly
inorganic arsenic, which is more toxic than organic forms. Soil samples throughout the Site
contained relatively low arsenic concentrations, slightly exceeding the Regional Screening Level of
3 mg/kg for Industrial Soil (including the background concentration of 5.1 mg/kg), but this is not
uncommon for Utah soils.
The stormwater retention pond appears to be the only surface water body sampled at the Site
that exhibits significantly elevated concentrations of arsenic above relevant screening levels in both
the surface water and sediment, and the risk of contaminant migration to other areas is low. The
likely source of contamination is from arsenic-containing urban and rural stormwater runoff that
has been transported to the pond and accumulated over time. Although there is a potential risk of
human exposure at the stormwater retention pond, West Valley City will implement measures to
ensure public access in this area is limited. Further investigations under CERCLA are not warranted
at this time; therefore, the DERR recommends a designation of No Further Remedial Action
Planned for the Site.
If you have any questions, please contact me at [phone], or via email at
[e-mail].

State Painting – UTN000820797

1.0 INTRODUCTION

Under authority of the Comprehensive Environmental Response, Compensation, and Liability
Act (CERCLA) of 1980, the Superfund Amendments and Reauthorization Act (SARA) of 1986,
in accordance with the National Oil and Hazardous Substances Pollution Contingency Plan
(NCP), and through a Cooperative Agreement with the U.S. Environmental Protection Agency
(EPA) Region 8, the Utah Department of Environmental Quality (UDEQ), Division of
Environmental Response and Remediation (DERR), has prepared this Site Inspection Analytical
Results Report (ARR) for State Painting (EPA SEMS ID# UTN000820797), located at 6594
Parkway Boulevard in West Valley City, Salt Lake County, Utah. This ARR presents data on the
sampling performed on the West Valley City (WVC) wetlands property (herein referred to as the
“Site”), located west and north-adjacent to the State Painting property.

A DERR Site Inspection Work Plan (SIWP) was initiated after arsenic contamination was
discovered in a stormwater retention pond at the Site during an EPA Removal Action on the
State Painting property in May 2018. The Removal Action included removing and disposing of
spent blast material containing chromium and hexavalent chromium that was spread across the
property, several drums containing sandblasted lead-based paint, and other numerous containers
and drums consisting of hazardous substances that posed a risk to nearby residences and the
wetlands to the west and north of the property. During removal activities, surface water and
sediment samples were collected from the stormwater retention pond to analyze for total and
dissolved metals, volatile organic compounds (VOCs), and semi-volatile organic compounds
(SVOCs). The analytical results for metals indicated elevated arsenic concentrations in the
surface water as high as 757 micrograms per liter (µg/L) for total arsenic and 764 µg/L for
dissolved arsenic (Table 1; Matrix Spike/Matrix Spike Duplicate; MS/MSD). Arsenic
concentrations in sediment samples ranged from 68.6–76.3 milligrams per kilogram (mg/kg)
(Table 1).

This ARR presents new analytical data from sampling at the Site in August 2023, summarizes
pertinent results, discusses potentially hazardous conditions, describes data gaps, and determines
if further work under CERCLA is warranted at the Site.

2.0 OBJECTIVES

The primary objective of the sampling performed at the Site was to determine the current status
and extent of arsenic contamination that could potentially pose a risk to human health and the
environment. The objectives of the sampling associated with this ARR were to:

Site Inspection Analytical Results Report

State Painting – UTN000820797

• Evaluate arsenic concentrations in the surface water and sediment from the stormwater
retention pond, and characterize the main form of arsenic;
• Evaluate arsenic concentrations in the surface soil and additional surface waters and
sediments at the Site;
• Evaluate the potential sources of arsenic contamination and determine if arsenic
contamination from the stormwater retention pond is migrating or has the potential to
migrate off-site via the surface water and overland flow;
• Evaluate human health and environmental exposure routes and determine exposure risks
for surface water, soil exposure, and air pathways; and,
• Determine if continued assessment under CERCLA or another appropriate authority is
warranted.

3.0 SITE LOCATION AND DESCRIPTION

The Site is situated in the northwest corner of WVC in Salt Lake County, Utah, at approximately
40° 42' 38" North Latitude and -112° 02' 59" West Longitude (Esri Inc. 2022; Figure 1). The
WVC Parks and Recreation maintenance building is located on the Site at 2729 South 6750 West
(Figure 2). The Site consists of approximately 83 acres of wetlands composed of perennial and
ephemeral ponds owned by WVC, immediately west and north (downgradient) from the State
Painting property (Figure 2). A large portion of the wetlands is zoned as low-density residential
and limited agricultural uses (Salt Lake County Assessor n.d.). The stormwater retention pond is
a natural pond of approximately 3.3 acres and is used for flood control; however, it’s a playa and
dry most of the year, consisting of a salt residue layer that doesn’t allow for plant growth (WVC
Parks and Recreation, phone communication, June 8, 2022).

One ranch-style home is located on the west side of 6750 West across from the Parks and
Recreation building, and another home resides on the northwest corner of 6750 West and
Parkway Boulevard. The Magna Water Treatment Plant is located at the northern end of 6750
West on a no-through road, and two Magna City well fields are located to the west (Barton) and
east (Haynes) of the Site (Figure 2). The surrounding area consists of mixed rural, residential,
and commercial land. Small farms and older homes predominate the north side of Parkway
Boulevard near the Site, and a newer subdivision is located on the south side of Parkway
Boulevard. The Riter Canal and several commercial warehouses are located near the Site’s north
property boundary.

4.0 SITE HISTORY

Historical satellite imagery shows nearly no changes in the WVC 83-acre property since 1997
(Google Earth Pro n.d.). The land was historically used for agriculture and was acquired by
WVC Parks and Recreation in 2019. Prior to 2019, it was owned by the WVC Public Works
Department since 2000, but some parcels of the property were acquired over time during 2002,
2010, and 2013 (WVC Public Works, email communication, December 20, 2022). The Magna
Water Treatment Plant was built in 2008 and the WVC Parks and Recreation maintenance
building was built in 2019 (Google Earth Pro n.d.; Salt Lake County Assessor n.d.). Two
residential homes located on 6750 West were built in 1949 and 1951, and the development of the
subdivision south of Parkway Boulevard began in 2005 (Google Earth Pro n.d.; Salt Lake
County Assessor n.d.). The DERR was notified by WVC that construction on the property for a
public park will begin in the spring of 2024 and will include pavilions, walking trails, restrooms,
a learning barn, an equestrian arena, a 9-hole disc golf course, and other attractions.

4.1 Previous Investigations: State Painting

In July 2016, the independent contractor, State Painting, contracted with the Jordan Valley Water
Conservancy District (JVWCD) to perform tank painting and repair work that included the
removal of lead-based paint from the exterior of a one million-gallon steel water tank. All
abrasive and other associated waste material used for the paint removal was collected and stored
in six 55-gallon drums. The engineering firm Infinity Corrosion Group, Inc. (ICG) was hired by
JVWCD to act as Project Engineer and oversee State Painting’s work.

The UDEQ Division of Waste Management and Radiation Control (DWMRC) received a call
from ICG on December 15, 2016, stating that six waste drums containing spent blast media and
lead-based paint from a JVWCD work site were improperly managed by State Painting. ICG
explained they instructed State Painting not to remove the six drums of waste from the work site
until they collected samples and received the laboratory analytical results for Toxicity
Characteristic Leaching Procedure (TCLP) for lead. State Painting informed ICG that two
samples were collected and submitted to American West Analytical Laboratories in November
2016; however, ICG discovered that State Painting removed the six drums from the work site
and transferred them to the State Painting property without receiving the laboratory results first.
The following outline of events were discussed in the SIWP (DERR 2023a) and are summarized
below:

Site Inspection Analytical Results Report

State Painting – UTN000820797

• On December 2, 2016, ICG collected six samples from the six waste drums at the State
Painting property due to not receiving analytical results from the laboratory that State
Painting submitted samples to previously.

• Laboratory records indicate the samples previously collected by State Painting were not
received by the laboratory until December 9. The analytical results for the two samples
collected indicated the TCLP for lead was below the regulatory level of 5 mg/L;
however, it was not known where the samples were taken from, and there was no
documentation on the Chain-of-Custody (COC) form for the date the samples were taken,
and may or may not have been received within the method-specific holding time
(DWMRC 2017a).

• On December 16, 2016, ICG submitted the samples they collected on December 2 to
American West Analytical Laboratories for TCLP lead analysis.

• On December 21, 2016, the DWMRC and Salt Lake County Health Department visited
the State Painting property. The DWMRC noted drums and buckets of unknown material
were stored in several outbuildings and trailers, and the six waste drums that were
removed from the work site were stored on a flatbed trailer. The resident reported her
son, the owner of State Painting, buried buckets and other materials behind her house and
disposed of toluene along the north end of the property. Additionally, she stated her son
spread spent blast media (Green Diamond grit) from the work performed on the interior
of the JVWCD water tanks onto their property to fill in low areas. The DWMRC
inspectors collected two samples of the spent blast media and one waste sample each
from three of the six drums for TCLP lead analysis.

• On December 28, 2016, ICG received the analytical results from samples collected on
December 16. Results indicated three of the six samples exceeded the TCLP regulatory
level of 5 mg/L for lead and therefore were characterized as hazardous waste. (DWMRC
2017a).

• The analytical results from the samples collected by the DWMRC on December 21
indicated two of the three drums failed the TCLP for lead and therefore were
characterized as hazardous waste.

• The DWMRC issued a Notice of Violation (NOV) to State Painting on April 12, 2017,
outlining failure to obtain an EPA identification number from the Director prior to

Site Inspection Analytical Results Report

State Painting – UTN000820797

transporting and storing hazardous waste, transporting hazardous waste without a
manifest, and disposing of solid waste without a permit (DWMRC 2017b).

• The DWMRC issued a NOV to JVWCD on September 22, 2017, which included an order
for JVWCD to develop a Sampling and Analysis Plan (SAP) for the State Painting
property.

• The DWMRC reviewed the SAP prepared by Environmental Resource Management
(ERM) on behalf of JVWCD and it was finalized on March 15, 2018. The SAP aimed to
assess if contaminants within the ground media and one drum containing unknown
material were potentially hazardous, if concentrations exceeded the EPA Regional
Screening Levels (RSLs) for Resident Soil, and if there was a potential for groundwater
contamination.

• On March 28, 2018, the DWMRC and ERM collected soil samples from the State
Painting property. The samples were analyzed for total metals, TCLP for metals,
hexavalent chromium (chromium-6), SVOCs, and VOCs. Analytical results showed all
chromium-6 concentrations (0.64–59.94 mg/kg) exceeded both the RSL for Resident Soil
and Dilution Attenuation Factor (DAF)-20 groundwater protection value, and total
chromium (171–1,560 mg/kg) was significantly elevated compared to chromium-6
concentrations in all samples (Table 2). Metals did not exceed TCLP values; however, it
was noted several metals were leachable, and other elevated concentrations of arsenic,
benzyl alcohol, cobalt, lead, and nickel exceeded either the RSL for Resident Soil, the
DAF-20, or both (Table 2). Several SVOCs and polycyclic aromatic hydrocarbons were
detected at low concentrations. Three waste samples were analyzed for VOCs but were
not detected above the reporting limit.

• Based on the analytical results, the DWMRC recommended further evaluation through
the EPA Emergency Removal Branch. The EPA On-Scene Coordinator and Superfund
Technical Assessment and Response Team (START) contractor, Weston Solutions,
mobilized to the State Painting property on May 9, 2018.

• On May 10, 2018, Weston Solutions collected a background soil sample and several soil
samples containing the spent blast media from the property. Analytical results showed
total chromium concentrations ranged from 2,130 mg/kg to 2,460 mg/kg, which was
approximately 100 times greater than the background concentration of 19.9 mg/kg
detected in a sample from an in-home daycare property located across the street (Table
3). Chromium-6 concentrations ranged from 0.847 mg/kg to 1.41 mg/kg, which exceeded

Site Inspection Analytical Results Report
6

State Painting – UTN000820797

the Resident Soil RSL of 0.3 mg/kg (Table 3). Arsenic concentrations exceeded the
Resident Soil RSL of 0.68 mg/kg but were not notably high except for one concentration
of 18.5 mg/kg; the background concentration was 9.9 mg/kg (Table 3).

• On May 31, 2018, Weston Solutions collected surface water and sediment samples from
the WVC stormwater retention pond located along the western perimeter of the State
Painting property, and the samples were analyzed for total and dissolved metals, VOCs,
and SVOCs. Three surface water samples (including one field duplicate) detected total
arsenic at concentrations of 666 µg/L, 743 µg/L, and 703 µg/L, and the MS/MSD for
total arsenic was 757 µg/L (Table 1). Dissolved arsenic was detected at concentrations of
662 µg/L, 709 µg/L, and 701 µg/L; the MS/MSD for dissolved arsenic was 764 µg/L
(Table 1). Arsenic concentrations for three corresponding sediment samples were
detected at 74.3 mg/kg, 76.3 mg/kg, and 68.6 mg/kg; the MS/MSD was 74.3 mg/kg
(Table 1).

• On June 3, 2018, the EPA signed an Action Memorandum to initiate a cleanup of the
State Painting property. The cleanup involved the excavation and disposal of
contaminated soil as well as the collection and disposal of abandoned containers and
drums.

• Following the EPA cleanup, the DERR collected confirmation soil samples from three
different areas of the property on June 13, 2018. Each soil sample was a composite of
five aliquots taken at a depth of six inches or less below ground surface (bgs) and was
analyzed for total metals. Chromium concentrations in zones 1–3 were 0.044 mg/kg, 0.16
mg/kg, and 0.015 mg/kg, respectively; lead concentrations in zones 1–3 were 0.04 mg/kg,
0.033 mg/kg, and 0.033 mg/kg, respectively; and arsenic concentrations in zones 1–3
were 0.0094 mg/kg, 0.0092 mg/kg, and 0.0095 mg/kg, respectively. The results
confirmed there were no exceedances above the EPA RSLs based on a target cancer risk
of 10-6 and a target hazard quotient of 0.1 (DERR 2018).

• EPA contractors and equipment were demobilized, and the abandoned drums and
containers consisting of hazardous materials were shipped to an appropriate facility for
disposal in July 2018. Since the source of the arsenic found in the WVC stormwater
retention pond was unknown, the EPA recommended a follow-up investigation by the
DERR.

5.0 FIELD ACTIVITIES

Site Inspection Analytical Results Report
7 State Painting – UTN000820797
Sampling was conducted at the Site on August 7, 9, 10, and 14, 2023. Sample locations are
shown in Figure 3 and XRF locations are shown in Figure 4. Field activities are summarized
below:
•Due to the short window of available surface water, six surface water samples and four
sediment samples were collected at the stormwater retention pond first on August 7
(Tables 4, 5). The surface water samples included two samples for total metals, two
samples for dissolved metals, and two samples for inorganic arsenic analysis.
•Thirty in-situ soil scans for heavy metals were performed throughout the WVC property
with a portable X-ray fluorescence (XRF) unit on August 9.
•Sixteen surface water samples (eight samples for total metals and eight samples for
dissolved metals), eight sediment samples, and two soil samples were collected on
August 10 (Tables 4, 5, 6).
•Two surface water samples (one sample for total metals and one sample for dissolved
metals), one sediment sample, and three soil samples were collected on August 14
(Tables 4, 5, 6).
Field activities were coordinated by DERR Project Manager Robin Keeler and are documented
in the Site Inspection Work Plan Field Activities Report (Appendix A). Photographs and GPS
coordinates were taken at each sample location. All field data was entered into a Survey123
electronic form and documented on field data sheets as a backup (Appendix B). Consent for
access to properties owned by West Valley City was obtained from the City Manager prior to
field activities (Appendix C). COC forms and sample documentation were prepared using Scribe
software for samples shipped to the EPA’s contract laboratory, and a separate COC form and
sample labels for samples analyzed for inorganic arsenic were provided by Eurofins
Environment Testing Northwest (Eurofins Seattle). COC records are provided in Appendix D.
5.1 Sampling Methods
Water quality measurements were performed in the field with a Horiba U-50 multi-parameter
water quality meter at surface water sample locations on August 7 and 10, 2023. The Horiba was
auto-calibrated using a pH buffer standard 4.01 solution at the office prior to leaving for field
sampling. The Horiba, cap, and collection cup were rinsed with a spray bottle of deionized water
after measurements were performed at each water body.

Site Inspection Analytical Results Report

State Painting – UTN000820797

Surface water samples were collected 0–2 inches below surface water using a Masterflex® L/S®
peristaltic pump portable sampler. A short piece of 3/16” inner diameter by 3/8” outer diameter
silicone tubing was inserted into the pump head, and a .17” inner diameter by 1/4” outer diameter
polyethylene tubing was inserted into the ends of the silicone tubing. One end of the
polyethylene tubing was affixed to a garden rake with zip ties and was extended out into shallow
water to avoid sediment disturbance with our feet while collecting the water. The other end of
the tubing was used to collect water directly into 500 and 250-milliliter (mL) TraceClean® high-
density polyethylene (HDPE) sample bottles. Water was purged for approximately 30 seconds
before filling the sample bottles. After samples were collected for total metals, the polyethylene
tubing was removed from the end where water was collected and a disposable filter was inserted
into the silicone tubing to collect for dissolved metals.

Five mL of nitric acid was added to the samples after collection for preservation except for the
sample bottles for inorganic arsenic analysis, which were prefilled with hydrochloric acid for
preservation. All samples were labeled and placed in an ice cooler after collection. A water depth
measurement was taken with a water level gauge where water was collected and recorded on
field data sheets. All tubing, disposable gloves, and filters were disposed of in a garbage bag and
replaced for each different sample location to avoid cross-contamination.

Sediment samples were collected with stainless steel spoons 0–2 inches bgs where surface water
samples were collected except where sediment couldn’t be reached or was obstructed by sticks,
then it was collected at the banks. Small sticks and vegetation that were easily visible were
removed before placing the sediment in 8 oz. glass sample jars. Sediment samples collected for
inorganic arsenic analysis were placed in 4 oz. polypropylene bottles. All samples were labeled
and placed in an ice cooler after collection. Disposable gloves and spoons were replaced at each
different sample location to avoid cross-contamination.

Field screening with a Thermo ScientificTM NitonTM XL2 Goldd XRF Analyzer was used to
determine potential “hot spots” of elevated arsenic around the Site prior to collecting soil
samples (Figure 4). Locations were screened in areas near future walking trails and attractions
once the property is developed into a park according to the draft Master Plan provided by WVC
(Appendix E). Prior to scanning surface soil, two system checks and a standard test using a sand
matrix spiked with a known concentration of metals including arsenic were performed each time
the unit was turned on and after 20 shots. Surface soil was cleared of grass and small rocks prior
to being scanned, and the XRF trigger was held for a maximum duration of 120 seconds per
scan. All XRF locations were assigned a shot number, marked with pin flags, and photographs
and GPS coordinates were taken.

Site Inspection Analytical Results Report

State Painting – UTN000820797

In order to determine sample locations for lab correlation, XRF results were sorted into low,
medium, and high range values from 30 XRF readings, and five locations were randomly
selected using the Microsoft Excel random number generator function. The background soil
sample was previously determined to be collected from the south side of Parkway Boulevard
near a residential area west of a drainage channel (SP-SO-05; Figure 3). Soil samples were taken
at a depth of 0–2 inches bgs using stainless steel spoons and placed into resealable clear plastic
storage bags labeled for identification. The storage bags served as a temporary container until the
soil was later sieved, returned to the bag, and scanned three times in the bag with the XRF to
obtain an average reading; then the sample was transferred into 8 oz. glass jars. Disposable
gloves and spoons were replaced at each unique sample location to avoid cross-contamination.
All samples were placed in a dry cooler after collection.
6.0 DEVIATIONS FROM THE WORK PLAN

Deviations from the SIWP (DERR 2023a) are outlined below. These changes did not alter the
ability of this ARR to sufficiently describe conditions at the Site.

• The SIWP stated 12 surface water samples plus one field duplicate would be collected,
but it was later realized that the dissolved water samples were not accounted for and
needed their own sample ID number; the SIWP did not provide ID numbers for dissolved
surface water samples. All dissolved surface water samples were labeled with the same
assigned ID as total metals followed by “-DSLVD.”

• The dissolved oxygen (DO) water quality readings on the Horiba U-50 were not recorded
on data sheets for the surface water sample locations due to a torn membrane cap for the
DO sensor. A phone conversation with a Horiba representative confirmed this would not
affect other water quality parameters. Additionally, the water temperature sensor was not
manually calibrated prior to fieldwork, and the recorded values may have some degree of
inaccuracy.

• When arriving at the Site on August 7, the original sampling location for SP -SW-05, SP-
SW-05-DSLVD, SP-SE-05, SP-SW-06, and SP-SE-06 was dried up. The location for
these samples was moved approximately 300 feet southwest where there was enough
water to sample.

• The SIWP stated XRF readings would be taken from approximately 40 locations within
the WVC property, however, it was determined in the field that 30 locations were a
sufficient representation.

• Tables 5, 6, and 7 in the SIWP identifies SP-SO-02 as the MS/MSD, however, the
MS/MSD was incidentally taken with SP-SO-01 instead of SP-SO-02.

• The sediment samples for SP-SE-11 and SP-SE-12 could not be collected at the same
location as the corresponding surface water samples due to the bank and bottom of where
the water was being collected being covered with boulders. Therefore, the sediment
samples were taken approximately 20 feet upstream from the surface water location along
the bank.

• Sampling events were originally anticipated to take two days to complete but were
completed in four separate events. Only a couple of hours of field crew help were
available for the first sampling event, and the XRF scanning throughout the WVC
property took a full day to complete. Due to time and scheduling constraints, samples SP-
SW-02, SP-SW-02-DSLVD, SP-SE-02, retake of SP-SO-01 for the MS/MSD, and retake
of SP-SO-03 for the field duplicate were collected on the fourth sampling event.

• It was noted in the SIWP that every effort would be made to ship samples to the
laboratory the day after the field sampling event, however, it was advised by the EPA
Contract Laboratory Program (CLP) manager to ship all the samples together after they
were all collected. This did not include the samples for the inorganic arsenic analysis;
those were shipped to Eurofins Seattle laboratory earlier on August 10. The day after the
last sampling event was spent entering data into the Scribe software for the CLP samples;
therefore, the CLP samples were not shipped until two days after the last sampling event,
on August 16. All samples were stored in a sample-designated refrigerator until ready for
shipment.

• The COC for Eurofins Seattle laboratory was incidentally never signed and dated by the
Project Manager. The analytical results are still applicable, but no qualifiers were applied
in the Data Validation Report due to this circumstance.

• The SIWP stated the surface water and sediment analytical results will be compared to
the National Oceanic and Atmospheric Administration (NOAA) Screening Quick
Reference Table (SQuiRT) ecological benchmark values; however, it was determined
since NOAA's Office of Response and Restoration decided to remove the SQuiRT cards
from their website because they are outdated, surface water samples were compared to
Utah Standards of Quality for Waters criteria for aquatic wildlife (Utah OAR 2023) and
sediment samples were compared to the Los Alamos National Laboratory (LANL)

benchmarks for aquatic community organisms (RAIS 2022).

7.0 WASTE CHARACTERIZATION

The contaminant of concern at the Site is arsenic. Arsenic occurs naturally in the earth’s crust,
and like many regions in the western U.S., a good portion of Utah soils contain elevated arsenic
concentrations due to the underlying parent rock materials. Arsenic is primarily obtained as a
byproduct of the smelting of copper, lead, cobalt, and gold ores. The U.S. ceased production of
arsenic in 1985, and most arsenic that is imported is used as a wood preservative for industrial
applications in the form of copper chromated arsenate (ATSDR 2007). Organic arsenic is used as
an herbicide primarily on cotton fields and turf and as an antimicrobial in feed additives for
poultry and swine. Inorganic arsenic pesticides have not been used for agricultural purposes
since 1993 (IARC 2012). Arsenic can become mobile and soluble when reduction conditions
occur in the soil during redox reactions, and it can be transported to surface waters during
surface runoff and also leach into the groundwater (ATSDR 2007). Arsenic is known to have
adverse effects on bird reproduction, egg hatchability, hatchling survivorship, and can cause
neurobehavioral disorders and death (Eisler 1988). Most human cases of adverse health effects
from exposure to arsenic are from inorganic arsenic, and breathing high levels can cause throat
and lung irritation, while oral exposure can cause nausea, vomiting, diarrhea, neurological
effects, and reproductive effects, and ingesting very high levels can result in death (ATSDR
2007). Long-term exposure to arsenic in drinking water is linked to increased risks of cancer in
the skin, lungs, liver, bladder, and kidney. The IARC classifies arsenic and inorganic arsenic
compounds as “carcinogenic to humans,” and the NTP’s 15th Report on Carcinogens classifies
arsenic and inorganic arsenic compounds as “known to be human carcinogens” (IARC 2012;
NTP 2021).

The DWMRC reported one soil sample collected from the State Painting property on March 28,
2018, had an elevated arsenic concentration of 44.4 mg/kg, but four other soil samples had
arsenic concentrations of less than 2 mg/kg (Table 2). Soil samples collected from the State
Painting property by Weston Solutions on May 10, 2018, showed the highest concentration of
arsenic was 18.5 mg/kg, and concentrations were less than 2 mg/kg in three locations (Table 3).
Additionally, several soil samples from May 10 were analyzed for TCLP for metals but were
either not detected above the detection limit or were well below the regulatory levels for defining
the characteristic of toxicity for hazardous waste. Surface water and sediment samples collected
from the stormwater retention pond on May 31, 2018, showed total and dissolved arsenic
concentrations were detected in the surface water as high as 757 µg/L and 764 µg/L,
respectively, and as high as 76.3 mg/kg in the sediment (Table 1).

Site Inspection Analytical Results Report
12

State Painting – UTN000820797

The surface water and sediment results from samples collected from the stormwater retention
pond in August 2023 showed lower arsenic concentrations compared to 2018. The dissolved
surface water results indicate arsenic concentrations exceed the aquatic wildlife benchmarks for
Utah Standards of Quality for Waters, with concentrations of 370 and 450 µg/L (Table 4). The
sediment sample results indicate arsenic concentrations exceed the Low Effect Ecological
Screening Level for aquatic community organisms, with concentrations ranging from 38–48
mg/kg (Table 5). Two surface water samples collected and analyzed for inorganic arsenic had
concentrations of 230 µg/L (SP-SW-04) and 370 µg/L (SP-SW-06) (Table 4). The corresponding
sediment samples analyzed for inorganic arsenic had concentrations of 48 mg/kg (SP-SE-04) and
38 mg/kg (SP-SE-06) (Table 5).

7.1 Waste Sample Locations

Twenty-four surface water samples (including two field duplicates), 13 sediment samples
(including one field duplicate), and 5 soil samples (including one field duplicate) were collected
from the Site in August 2023 to determine contaminant source areas, establish background
concentrations, and assess the risk of exposure to employees and future park visitors. Sample
locations were dependent on water accessibility and safety considerations. Sample locations,
descriptions, and rationale are provided in Table 7 and are shown in Figure 3. Photographs of
sample locations can be found in Appendix A.

7.2 Waste/Source Data Assessment

As specified by the EPA Hazard Ranking System (HRS), analytical results from field samples
are typically compared to analytical results from background samples and to the Sample
Quantitation Limit (SQL) for determining observed releases. An observed release by chemical
analysis is established when at least one hazardous substance in a release sample is significantly
increased above its background level (EPA 1992). When a sample concentration exceeds its
SQL, the following criteria are used for determining significance above the background level:

• If the background concentration is equal to or greater than its SQL (or its detection limit
if there is no SQL), the concentration in the release sample must be at least three times
greater than the background concentration; or

• If the background concentration is below its SQL, the concentration in the release sample
must be equal to or greater than the background SQL (EPA 1992).

The surface water, sediment, and soil samples collected on August 7, 10, and 14, 2023 were

Site Inspection Analytical Results Report

State Painting – UTN000820797

analyzed by the CLP, Chemtech Consulting Group. Surface water samples were analyzed for
total and dissolved metals under the EPA Superfund Analytical Methods (SFAM01.1) Statement
of Work, except for two surface water samples and two sediment samples collected from the
stormwater retention pond that were analyzed for inorganic arsenic by Eurofins Seattle under
method 1632A. Inorganic arsenic results can be used to compare to total organic arsenic results
to estimate how much of the total arsenic sample is in the form of inorganic arsenic, which is
generally more toxic than organic forms. The Data Validation Report for this ARR was
performed under the EPA START contractor, Tetra Tech, Inc.

Surface water samples were compared to the Utah Standards of Quality for Waters, numeric
criteria for aquatic wildlife, R-317-2-14 (Utah OAR 2023). The standards are based on dissolved
metals except for aluminum, which is based on total recoverable metals. Although the area
sampled does not have a designated beneficial use class, it’s known to be frequented by
waterfowl, shore birds, and other water-oriented wildlife, which would place it in Class 3D.
Hardness-dependent metals include cadmium, copper, lead, nickel, silver, and zinc. For these
metals, sample results for calcium and magnesium from each dissolved surface water sample
were incorporated into a hardness calculator, and conversion factors for the ratio of total
recoverable metals to dissolved metals were computed for acute and chronic values. The
maximum hardness per this criterion is 400,000 µg/L. The adjusted acute and chronic values for
hardness-dependent metals are noted in Table 4. For aluminum, the pH of all water bodies was
greater than seven and the hardness for all total aluminum samples was greater than 50,000 µg/L;
therefore, the chronic criterion does not apply.

Utah’s aquatic life criteria are very similar to the EPA's National Recommended Water Quality
Criteria - Aquatic Life Criteria Table. Although the sampled areas are not drinking water
sources, the EPA Maximum Contaminant Level (MCL) is provided as a frame of reference in
Table 4. Sediment samples were compared to the LANL benchmarks for aquatic community
organisms using the Low Effect Ecological Screening Levels (ESLs) (RAIS 2022). The Low
Effect ESLs are very similar to the SQuiRT Probable Effect Concentration values for inorganics
in sediment. Soil samples were compared to the EPA’s RSL for Industrial Soil based on a target
cancer risk of 10-6 and a target hazard quotient of 0.1 (EPA 2024). Exceeding a given benchmark
does not constitute a confirmed threat to human or environmental health; rather, exceeding a
benchmark is an indication that a sampling location might warrant further consideration along
other site-specific factors.

8.0 GROUNDWATER PATHWAY

Site Inspection Analytical Results Report
14

State Painting – UTN000820797

8.1 Hydrogeology

Groundwater in the Salt Lake Valley generally moves laterally from the mountain fronts in the
direction of the potentiometric surface gradient towards the center of the valley, where it
becomes confined by fine-grained sediments, and eventually flows west-northwest towards the
Jordan River and the Great Salt Lake (Thiros 1995). Four main aquifer systems consist of a
confined (artesian) aquifer, a shallow unconfined (water table) aquifer overlying the confined
aquifer, a deep unconfined aquifer between the confined aquifer and the mountains, and
localized unconfined perched aquifers. The confined aquifer and the deep unconfined aquifers
together constitute the principal aquifer, which is the primary source of groundwater withdrawn
from wells (Hely, Mower, and Harr 1971).

The confined aquifer consists of Quaternary deposits of clay, silt, sand, and gravel, which are all
hydraulically interconnected with individual beds ranging in thickness but can extend to more
than 1,000 feet in the northern part of the valley (Hely, Mower, and Harr 1971). The deep
unconfined aquifer along the margins of the Wasatch Range and Oquirrh Mountains consists of
thick, coarse-grained deposits with no confining layers; thus, it supplies much of its water to the
confined aquifer and is the primary recharge area in the valley for the principal aquifer (Baskin
1990; Thiros 1995). In the primary and secondary (downgradient) recharge areas, the direction of
groundwater moves from the land surface to the shallow unconfined aquifer, which is primarily
composed of clay, silt, and fine sand, and then moves to the principal aquifer. The Site is a
wetlands area where groundwater discharge occurs, e.g., the direction of groundwater flow
moves upward from the principal aquifer to the water table; however, groundwater recharge can
also occur seasonally.

Within the valley, information from well logs indicates a large portion of Tertiary deposits
consist of semi-consolidated clay, sand, and gravel intermixed with lava, and include cemented
layers of sand and gravel which yield a small quantity of water to wells (Arnow, Van Horn, and
Lapray 1970). Conversely, the overlying unconsolidated Quaternary deposits can be very porous
and permeable, yielding a large quantity of water to wells. Groundwater samples were not
previously collected at the Site or State Painting property; however, groundwater sampling
conducted in 2017 approximately two miles northeast at the CERCLA Bland Landfill site
(SEMS ID# UTN980635932) encountered groundwater at depths of 5.6–10.5 feet bgs, and local
groundwater flow was to the north-northwest (DERR 2022).

8.2 Groundwater Targets and Conclusions

There are 2,497 underground points of diversion located within four miles of the Site (UDNR,

Site Inspection Analytical Results Report
15

DWR 2020). Of these, 941 include municipal and/or domestic uses, excluding abandoned wells.
The Magna Water District operates two municipal drinking water well fields: the Barton Well
Field, located approximately one-quarter of a mile northwest (downgradient) from the
stormwater retention pond, and the Haynes Well Field, located approximately three-quarters of a
mile east (upgradient) from the stormwater retention pond (Figure 2). The wells draw water from
units as shallow as 100 feet bgs, generally drawing water from a gravel zone of 100–400 feet bgs
(UDNR, DWR 2009a). The Magna Water District is part of a blended water system that includes
purchased water from JVWCD and serves a population of approximately 32,100 people (DDW
2023). The Magna Water Treatment Plant located near the Barton Well Field incorporates
electrodialysis reversal (EDR), a process that uses an adjustable direct current field applied
across ion-exchange membranes to reduce total dissolved solids, naturally occurring arsenic, and
perchlorate concentrations in the water supply (Magna Water District 2021). Samples collected
from the EDR feed, EDR finished blend, and water treatment plant are routinely submitted to the
Utah Division of Drinking Water in compliance with the Safe Drinking Water Act. Arsenic
concentrations analyzed during 2018–2022 from the EDR feed indicated several groundwater
samples exceeded the EPA drinking water Maximum Contaminant Level (MCL) of 10 μg/L,
ranging from 10 to 11.9 μg/L (DDW n.d.). Arsenic concentrations analyzed from the EDR
finished blend and water treatment plant during 2018–2022 showed levels below the MCL
except for one occurrence where the EDR finished blend had a concentration of 10 μg/L of
arsenic in 2018 (DDW n.d.).

In addition to Magna Water District, two wells operated by Kearns Improvement District (KID)
supply drinking water to communities within a three-mile radius south (upgradient) of the Site.
The system includes blended water from JVWCD. The KID conducts water quality sampling
quarterly from one combined pump station, and the two wells south of the Site are only used
during the summer (KID, phone communication, March 27, 2023). The 2022 and 2023 water
quality reports indicate the highest concentration of arsenic was detected at 6.2 μg/L and 5.1
μg/L, respectively (KID 2022; 2023).

There are four non-community non-transient water system wells operated by Kennecott Utah
Copper located within a two-mile radius northwest (downgradient) from the Site (Kennecott-
Section 21, Figure 2). Monitoring locations for the four wells were combined into one sampling
station in 2008, and sampling results from 2008 detected arsenic at 16 μg/L (DDW n.d.).
Sampling results during 2009–2012 detected a range of arsenic from 12 μg/L to 14 μg/L, and
results from sampling during 2014, 2017, and 2022, detected arsenic concentrations at 13 μg/L,
15 μg/L, and 10 μg/L, respectively (DDW n.d.). In 2012, Point of Use Arsenic Treatment Units
were established at several locations, where water undergoes reverse osmosis before being
dispensed. The units are sampled quarterly in accordance with Kennecott’s operation permit.

Site Inspection Analytical Results Report
16

State Painting – UTN000820797

During 2012–2022 arsenic concentrations at these units were either below the contract-required
detection limits or below the MCL of 10 μg/L; there was only one instance where sampling
results from one treatment unit detected arsenic at 11 μg/L in August 2013 (DDW n.d.). The
results from the quarterly sampling of the treatment units in February 2023 did not detect arsenic
above the contract-required detection limit (DDW n.d.).

The nearest private underground water well is located approximately one-quarter of a mile
southeast (upgradient) from the Site. The total depth of the well is 105 feet bgs with depth to
water at 16 feet bgs (UDNR, DWR 2009b). According to water rights records from the 1980s,
the well is used for irrigation and stock watering and is no longer used for domestic purposes due
to the public service connection with Magna Water District. A second private well is located
approximately one-half mile west of the Site. The total depth of the well is 100 feet bgs and
listed uses include irrigation and stock watering (UDNR, DWR 2009c). This well was sampled
in August 2008 under the Utah Department of Agriculture and Food State Ground Water
Program, and results detected arsenic below the MCL at a concentration of 5.2 μg/L (UDNR,
DWR 2009c). The Utah Division of Water Rights map server indicates that other numerous
private wells are located in downgradient residential areas west and north of the Site, but it’s
unlikely that homes continue to use private wells for drinking water due to public water supply
connections with the Magna Water District.

Due to the current low risk of arsenic exposure via the groundwater pathway within the four-mile
radius of the Site, groundwater samples were not collected as part of the SIWP.
9.0 SURFACE WATER PATHWAY

9.1 Hydrology

The stormwater retention pond is a natural pond approximately 3.3 acres that receives less than
0.01% of WVC’s water runoff (WVC Public Works, email communication, December 20, 2022).
On average, the pond is approximately two feet deep during the first part of the year but dries up
during the summer months. There is one inlet that drains into the area located near the southwest
corner of the stormwater retention pond, but the pond does not have any outlets. Stormwater and
irrigation runoff near the pond flows east through a culvert south of Parkway Boulevard,
converges with an open drainage ditch near the southern subdivision, and flows north in an
underground tunnel into the wetlands area. An additional inlet drainage is located immediately
south of the Magna Water Treatment Plant and flows east into the wetlands area. Water then
flows into a larger pond complex just north of the stormwater retention pond. Within the city’s
35.5 square miles, approximately 20% of surface runoff drains into these larger perennial ponds,

Site Inspection Analytical Results Report
17

State Painting – UTN000820797

which are also fed by groundwater discharge (WVC Public Works, email communication,
December 20, 2022). Water flows out of this system and enters the Riter Canal, near the Site’s
north boundary (Figure 2). The Riter Canal receives water from urban and agricultural runoff
and from the North Jordan Canal, located approximately four miles southeast of the Site (SLCo
Public Works n.d.). Water in the Riter Canal flows west for approximately two miles, then
diverges north and enters the C-7 Ditch. Water in the C-7 Ditch flows north-northwest and
discharges into the Great Salt Lake, approximately 12 miles downstream from the Site (Figure
5).

Lee Creek is located within a one-mile radius northeast of the Site (Figures 2, 5). The creek
originates in this area near the Riter Canal, flows northwest, and discharges into the Great Salt
Lake near Gilbert Bay, approximately ten miles downstream from the Site. Historical data on the
flow rate taken near the discharge point in April 2008 was recorded as 12 cubic feet per second
(USGS n.d.).

9.2 Surface Water Targets

The stormwater retention pond is located immediately east of the WVC Parks and Recreation
maintenance building (Figure 2). The building is located on a no-through road and currently
receives little traffic; however, the WVC wetlands property will be developed into a public park
which will receive numerous visitors in the future. This will increase the potential risk of human
exposure to the contaminated pond, particularly when the pond dries up during the summer
months. The ponds on the Site do not support fisheries, but are frequented by waterfowl,
migratory birds, sandhill cranes, deer, and other wildlife (WVC Parks and Recreation, personal
communication, October 3, 2022). Anglers were observed fishing in the Riter Canal north of the
Site during the August 10, 2023 sampling event. There are no surface drinking water intakes
within the 12-mile downstream target distance limit of the Site (Figure 5).

The nearby Lee Creek is protected for beneficial uses of infrequent primary contact recreation
and waterfowl, shore birds, and associated aquatic life (DWQ n.d.). The National Audubon
Society manages the 305-acre Lee Creek Natural Area along Gilbert Bay as part of the South
Shore Preserve and Gillmor Sanctuary. The Lee Creek Natural Area provides critical habitat for
nesting and migrating birds, including Snowy Plovers, American Avocets, Long-billed Curlews,
and Spotted Sandpipers.

The Lee Kay Ponds are east-adjacent to Lee Creek and are managed by the Utah Division of
Wildlife Resources as a non-fishing conservation area that requires registration to access for
public use (UDNR, DWR 2023). The surrounding facilities include a public shooting range in

Site Inspection Analytical Results Report

State Painting – UTN000820797

the southeast corner of the property, a dog training area, and a warm-water fish hatchery that
breeds Northern Pike northwest of the shooting range. The area is also used for bird watching;
there have been over 221 bird species identified in the area, including 18 rare bird species
(UDNR, DWR 2023).

9.3 Surface Water and Sediment Sample Locations

Twenty-four surface water samples (including two field duplicates and dissolved samples) and
13 corresponding sediment samples (including one field duplicate) were collected during the
August 7, 10, and 14 sampling events (Tables 4, 5). Sample locations are shown in Figure 3 and
are described in Table 7. Total and dissolved samples were collected from the stormwater
retention pond located west-adjacent to the State Painting property, from four other pond areas in
the wetlands complex north of the stormwater retention pond, from an open drainage channel
near an underground tunnel south of Parkway Boulevard, from a drainage area on the southwest
corner of the Site, from a downstream location in the Riter Canal near the northwest corner of the
Site, and from an upstream location in the Riter Canal, northeast of the Site.

9.4 Surface Water and Sediment Analytical Results

9.4.1 Surface Water Results

The Utah Standards of Quality for Waters criteria for aquatic wildlife are based on the dissolved
analytical results (except for aluminum) which are generally a better approximation of the
concentration that is bioavailable to aquatic organisms (Utah OAR 2023). All dissolved surface
water results presented high concentrations of magnesium (23,000–220,000 µg/L), potassium
(15,000–1,700,000 µg/L), sodium (160,000–17,000,000 µg/L), and calcium (9,900–120,000
µg/L) (Table 4, Appendix F). The magnesium concentration of 220,000 µg/L (SP-SW-05-
DSLVD) was greater than three times the background concentration of 60,000 µg/L (SP-SW-13-
DSLVD). Potassium concentrations of 1,000,000 (SP-SW-03-DSLVD) and 1,700,000 µg/L (SP-
SW-05-DSLVD) were at least 50 times the background concentration of 20,000 µg/L. Sodium
concentrations of 17,000,000 (SP-SW-05-DSLVD) and 11,000,000 µg/L (SP-SW-03-DSLVD)
in the stormwater retention pond also grossly exceeded the background concentration of 240,000
µg/L, but these elevated concentrations are typical of saline playas. The highest concentration of
dissolved calcium was 120,000 µg/L (SP-SW-12-DSLVD) but was not greater than three times
the background concentration of 110,000 µg/L.

Dissolved arsenic concentrations of 370 μg/L (SP-SW-03-DSLVD) and 450 μg/L (SP-SW-05-
DSLVD) were detected in the stormwater retention pond and were significantly higher than the

Site Inspection Analytical Results Report
19

State Painting – UTN000820797

background concentration of 13 μg/L (SP-SW-13-DSLVD). These concentrations also exceed
both acute (340 μg/L; 1-hour average) and chronic (150 μg/L; 4-day average) standards for
aquatic wildlife. Samples SP-SW-04 and SP-SW-06 from the stormwater retention pond were
analyzed for inorganic arsenic and were detected in surface water at 230 µg/L and 370 µg/L,
respectively. In comparing these values to the total arsenic values of 390 μg/L (SP-SW-03) and
470 µg/L (SP-SW-05), it can be estimated that about 59% ([230/390]x100) and 79%
([370/470]x100) of the arsenic concentration is comprised of inorganic arsenic. However, it’s
noted that total arsenic includes both organic and inorganic arsenic, and there is no separate
measurable concentration and associated detection limit for organic arsenic; therefore, the results
cannot definitively isolate how much of the total arsenic is organic, which may slightly
overestimate the toxic potential. The second-highest dissolved arsenic concentration was
detected in sample SP-SW-02-DSLVD at 37 μg/L, located in a drainage area near the stormwater
retention pond on the southwest corner of the Site. The concentration is just under three times the
concentration of the background sample (13 μg/L) and does not exceed aquatic wildlife
benchmarks. Other dissolved arsenic concentrations across the Site were generally much lower,
ranging from 7.2 to 20 μg/L.

Elevated total aluminum concentrations of 1,400 μg/L (SP-SW-11), 1,500 μg/L (SP-SW-12), and
1,100 μg/L (SP-SW-13; background sample) were detected in the Riter Canal and surpassed the
acute standard of 750 μg/L. Total aluminum concentrations in other surface water samples were
generally much lower, particularly in the stormwater retention pond (17 μg/L and 26 μg/L). No
other analytes in surface water were detected significantly above background concentrations and
did not exceed aquatic wildlife benchmarks where applicable.

Water quality readings taken from the stormwater retention pond show the average water depth
was 0.25 feet, average water temperature was 29.5 °C (85.1 ℉), pH was 9.5, average oxidation-
reduction potential (ORP) was 67.5 millivolts (mV), average conductivity was 33.5
microsiemens per centimeter (mS/cm), average total dissolved solids (TDS) was 20.6 grams/liter,
and average salinity was 21 parts per thousand (ppt) (Appendix B). The high salinity,
conductivity, and TDS levels in the stormwater retention pond are consistent with characteristics
of a salty playa. The pH, salinity, conductivity, and TDS were considerably lower at other water
bodies sampled (Appendix B).

9.4.2 Sediment Results

Elevated concentrations of magnesium, potassium, sodium, and calcium in sediment samples
generally correlated with elevated concentrations in the corresponding surface water samples,
although most of the sediment concentrations were not greater than three times the background

Site Inspection Analytical Results Report
20

State Painting – UTN000820797

samples. However, a magnesium concentration of 39,000 mg/kg was detected in sample SP-SE-
05 from the stormwater retention pond, which is exactly three times the background
concentration of 13,000 mg/kg (SP-SE-13), and a sodium concentration of 20,000 mg/kg was
detected from the same sample, which significantly exceeds the background sample of 380
mg/kg (Table 5, Appendix F). Additionally, sample SP-SE-03 from the stormwater retention
pond showed a significantly high concentration of 19,000 mg/kg of sodium. Other concentrations
of sodium that were greater than three times the background concentration were detected in
samples SP-SE-07 (2,500 mg/kg), SP-SE-08 (2,400 mg/kg), and SP-SE-09 (1,200 mg/kg).

Arsenic concentrations in sediment samples SP-SE-03 (44 mg/kg) and SP-SE-05 (43 mg/kg)
from the stormwater retention pond significantly exceeded the background concentration of 5.8
mg/kg by slightly more than sevenfold. These concentrations also exceeded the LANL Low
Effect ESL of 33 mg/kg. Samples SP-SE-04 and SP-SE-06 from the stormwater retention pond
were analyzed for inorganic arsenic and were detected in sediment at 48 mg/kg and 38 mg/kg,
respectively. Given the total arsenic value of 44 mg/kg for sediment sample SP-SE-03 and the
corresponding inorganic arsenic value of 48 mg/kg for sample SP-SE-04, it can be estimated that
all of the arsenic concentration is in the inorganic form ([48/44]x100). Likewise, in comparing
the total arsenic of 43 mg/kg for SP-SE-05 and corresponding inorganic arsenic of 38 mg/kg for
SP-SE-06, it can be estimated that most (88%) of the arsenic concentration is in the inorganic
form ([38/43]x100). Arsenic concentrations in sediment at other sample locations did not exceed
the Low Effect ESL, ranging from 5.8 to 16 mg/kg.

Chromium concentrations of 45 mg/kg (SP-SE-01) and 66 mg/kg (SP-SE-02) significantly
exceeded the background concentration of 13 mg/kg, but these concentrations did not exceed the
Low Effect ESL benchmark of 110 mg/kg. Copper concentrations of 280 mg/kg (SP-SE-01), 93
mg/kg (SP-SE-03), and 130 mg/kg (SP-SE-07) are greater than three times the background
concentration of 25 mg/kg, and the copper concentration of 75 mg/kg (SP-SE-08) is exactly three
times the background concentration. The copper concentration of 280 mg/kg also exceeds the
Low Effect ESL benchmark of 140 mg/kg. One lead concentration of 57 mg/kg from the
stormwater retention pond (SP-SE-05) significantly exceeded the background concentration of
18 mg/kg, but did not exceed the Low Effect ESL benchmark of 120 mg/kg. One manganese
concentration of 1,300 mg/kg from the drainage area near the stormwater retention pond (SP-SE-
02), significantly exceeded the background concentration of 390 mg/kg and exceeded the Low
Effect ESL benchmark of 1,100 mg/kg. One zinc concentration of 340 mg/kg from an open
drainage channel south of Parkway Boulevard (SP-SE-01) significantly exceeded the background
concentration of 57 mg/kg but did not exceed the Low Effect ESL benchmark of 450 mg/kg.
Other concentrations of metals in sediment were within acceptable screening limits.

9.5 Surface Water and Sediment Conclusions

The analytical results demonstrate that the stormwater retention pond appears to be the only
surface water body sampled at the Site that exhibits significantly elevated concentrations of
arsenic above relevant screening levels in both the surface water and sediment. This shallow
playa undergoes seasonal cycles of drying and refilling, receiving mineral input from urban
runoff during wet periods followed by evaporation and accumulation of magnesium, potassium,
and sodium ions, leading to very high ion concentrations when the pond refills. This is
exacerbated due to the closed system of this pond where there is no outflow, and shallow water
yields less dilution and higher concentrations of pollutants. The alkaline conditions and high
ionic strength in this pond can prevent arsenic from binding to particles, allowing a large
proportion to exist in the dissolved phase. This could explain the similar concentrations of
arsenic detected in both total and dissolved samples. The data also indicates most of the arsenic
in stormwater retention pond is in the form of inorganic arsenic, which is generally more soluble
in water than organic arsenic. This coincides with the fact that the stormwater retention pond
collects stormwater runoff that carries pollutants from streets, agricultural lands, commercial and
residential lawns, and construction sites. Inorganic arsenic is the more toxic form and is of
greater concern from a regulatory and human/wildlife health perspective.

Arsenic concentrations in the stormwater retention pond appear to have decreased since the
sampling in May 2018, which could be due to a seasonal difference in when the pond was
sampled; May would tend to have more spring precipitation and diffuse runoff than the normally
drier month of August and thus carry a greater influx of pollutants into the drainage areas.
Arsenic concentrations may also become displaced from flooding events or be redistributed in
the sediment load over time. Although arsenic concentrations were not found at the same levels
of magnitude in other sample locations and do not appear to be migrating, arsenic levels in the
stormwater retention pond pose a potential risk of exposure to humans and wildlife.

Total aluminum concentrations in surface water were elevated in the Riter Canal, including the
background concentration (1,100 µg/L), and exceeded the acute standard of 750 µg/L. These
concentrations were also significantly higher than the dissolved concentrations. The background
sediment sample for aluminum (6,300 mg/kg) was also higher than all the other sediment
samples except for SP-SE-01; 10,000 mg/kg. Total aluminum concentrations in water are
influenced by suspended particulate matter, which a large portion of aluminum is bound to,
resulting in a much higher concentration in the total versus dissolved samples. The Riter Canal
also likely receives a higher sediment load from erosion and stormwater runoff than the ponds,
resulting in higher total aluminum concentrations. The aluminum concentration of 10,000 mg/kg
in sediment was detected in a different canal; however, the corresponding surface water sample

Site Inspection Analytical Results Report
22

State Painting – UTN000820797

concentration was relatively low (120 µg/L; SP-SW-01). This is likely due to the low flow in this
canal, allowing for substantial deposition of aluminum-bound particulates that settle in the
sediment while only a small amount remains in the water. Other factors such as a more neutral
pH of 7.4 at this location can contribute to aluminum remaining in the particulate form and
accumulating over time. Calcium concentrations Site-wide were elevated in both surface water
and sediment samples (up to 120,000 µg/L in surface water and 110,000 mg/kg in sediment) but
were found at lower levels in the stormwater retention pond. Unlike aluminum, calcium tends to
remain in the dissolved phase rather than adsorb to particles, similar to the behavior of
magnesium, potassium, and sodium.

10.0 SOIL EXPOSURE PATHWAY

10.1 Geology

The Site is located along the northwestern edge of the Salt Lake Valley at an elevation of
approximately 4,241 feet above mean sea level, and the general topography slopes downgradient
to the northwest (EPA n.d.). The north-south trending intermontane valley lies on the eastern
edge of the Basin and Range Physiographic Province, and on the western edge of the Colorado
Plateau Province. The general geology of the valley is characterized by fine-grained sediments,
silts, and clays which were deposited from prehistoric Lake Bonneville, and by extensive
Quaternary and Tertiary deposits of conglomerates, sands, and silts deposited by the erosion of
and deposition from the surrounding mountain ranges (Hintze 1988). The mostly unconsolidated
saturated valley fill is more than 2,000 feet thick and is primarily composed of clay, silt, sand,
gravel, tuff, and lava (Hely et al. 1971).

Soils in the wetland area primarily consist of Lasil silt loam and Saltair silty clay loam from
lacustrine deposits, are strongly saline, and are characterized as hydrologic soil Group D; soils
having a very slow infiltration rate when thoroughly wet (e.g., high runoff potential), and a very
slow rate of water transmission (USDA, NRCS 2019). Soil lithology recorded from the well
driller log on the nearest private underground water well located approximately one-quarter of a
mile southeast (upgradient) from the Site, consisted of clay (0–32 feet bgs), sand (32–40 feet
bgs), clay and hardpan (40–55 feet bgs), gravel (55–62 feet bgs), clay (62–78 feet bgs), gravel
(78–84 feet bgs), and rock and gravel (84–105 feet bgs) (UDNR, DWR 2009b).

10.2 Soil Targets

The nearest residences include two homes located approximately 360 feet west and
approximately 400 feet southwest of the stormwater retention pond. The State Painting

Site Inspection Analytical Results Report
23

State Painting – UTN000820797

residential property is located approximately 400 feet southeast of the stormwater retention pond,
and two homes are located just east of the State Painting property. Several other homes are
located along the north side of Parkway Boulevard, and residential subdivisions are located on
the south side of Parkway Boulevard. It was noted in the EPA’s 2018 State Painting Action
Memorandum that an in-home daycare was operating across the street from the State Painting
property; however, the current status of the daycare operation is unknown.

The WVC Parks and Recreation maintenance building located immediately west of the
stormwater retention pond operates Monday–Friday and employs between 13–25 people
depending on the time of year (WVC Public Works, email communication, April 6, 2023). The
property is fenced off from the general public. There are no schools located within 200 feet of
the Site, but one school is located approximately 0.3 miles south (upgradient) from the Site and
one school is located approximately 0.7 miles northwest (downgradient) from the Site. Several
other schools are located 0.75 miles or more upgradient from the Site. Approximately 585 people
live within a quarter-mile radius of the Site (U.S. Census Bureau 2021).

10.3 XRF Soil Screenings and Soil Sample Locations

The XRF soil screening locations were based on areas where there was potential for a lot of foot
traffic or communal gathering once the property is developed into a park. Thirty XRF screenings
occurred during the August 9 sampling event. XRF locations are shown in Figure 4. Screening
zones included areas around the stormwater retention pond, north, northeast, and northwest of
the stormwater retention pond, north and west of the State Painting property, and near a playa on
the west side of 6400 West. Five soil samples (including one field duplicate) were collected on
WVC’s property during the August 10 and 14 sampling events. Sample locations are shown in
Figures 3 and 4 and are described in Table 7. The background soil sample (SP-SO-05) was
located on the south side of Parkway Boulevard near a residential area west of a drainage
channel (Figure 3). Two samples (including one field duplicate) were collected north of the
stormwater retention pond near a storage shed (SP-SO-03/04), one sample was collected in a
large field on the tail end of a playa west of 6400 West (SP-SO-02), and one sample was
collected in an open field north of a pond complex between SP-SW-08 and SP-SW-09 (SP-SO-
01).

10.4 XRF Soil Screening Results and Soil Analytical Results

XRF readings were only evaluated for arsenic and are shown in Table 8. Raw data for all metals
is included in Appendix G. Corresponding soil analytical results are shown in Table 6. All soil
analytical results exceeded the arsenic RSL of 3 mg/kg for Industrial Soil, ranging from 3.9–8.5

Site Inspection Analytical Results Report
24

State Painting – UTN000820797

mg/kg. The values for 30 arsenic XRF readings ranged from 4–15 mg/kg with a mean of 8
mg/kg. The maximum reading (15 mg/kg) was taken at the same location as soil sample SP-SO-
02 (Figure 4). The following comparisons of XRF arsenic results (based on the average of three
readings) versus fixed laboratory arsenic results taken from the same locations are closely
correlated, which suggests good confidence in the results:

XRF Shot # Sample ID # Arsenic – XRF
(mg/kg)
Arsenic – Laboratory
(mg/kg)
1223 SP-SO-01 11 6.7
1207 SP-SO-02 7 8.5
1204 SP-SO-03 4 3.9
1204 SP-SO-04 6 4.6
1198 SP-SO-05 6 5.1

10.5 Soil Conclusions

Low concentrations of arsenic were found in both XRF soil readings and soil analytical results.
Although all soil analytical results exceeded the arsenic RSL of 3 mg/kg for Industrial Soil
including the background sample (5.1 mg/kg), this is not uncommon for Utah soils; sampling
data from DERR historic site assessments showed the mean soil background level for arsenic
calculated from 18 sites in the Salt Lake Valley was 16 mg/kg (DERR 1999) and the background
soil sample collected during State Painting investigations on May 10, 2018, was 9.9 mg/kg.
Sediment sample results from the stormwater retention pond detected arsenic concentrations at
43 and 44 mg/kg, which will be exposed once the pond dries up. According to the city’s draft
Master Plan, a boardwalk will be constructed across the stormwater retention pond which may
help prevent direct contact with the soils. Additionally, WVC will be posting signs to keep off
the playa once the park is developed and accessible to the public (WVC Parks and Recreation,
personal communication, April 2, 2023). Aside from other playas on the Site that become
seasonal dry, the majority of areas are largely covered with thick vegetation and present a low
risk of exposure to soils.
11.0 AIR PATHWAY

11.1 Meteorology and Air Pathway Background

The Salt Lake Valley is located in a semi-arid climate where mountain ranges and the Great Salt
Lake strongly influence climate conditions. Long-term meteorological data recorded closest to
the Site was obtained from the Salt Lake City weather monitoring station. Over the time period

Site Inspection Analytical Results Report
25

State Painting – UTN000820797

1991–2020, the normal daily maximum temperature was highest in the month of July at 94.0 ºF
and the normal daily minimum temperature was lowest in the month of January at 24.2 ºF
(NCEI-NOAA n.d.). Normal precipitation is 15.52 inches/year. The two-year 24-hour rainfall is
1.28 inches (NOAA n.d.). Although wind conditions are variable at the Site, winds generally
come from the north/northeast with an average speed of 8.3 miles per hour (NCEI-NOAA n.d.).
During winter months, heavy fog can develop under temperature inversions and persist for
several days. These conditions allow for the creation of fine particulate matter (PM2.5) in
secondary aerosols to build up and become trapped in valleys at unhealthy air quality levels.

11.2 Air Pathway Targets and Conclusions

Approximately 119,441 people live within a four-mile radius of the Site (U.S. Census Bureau
2021). In addition to employees who work at the WVC Parks and Recreation maintenance
building, the nearest residences live within 360–400 feet of the stormwater retention pond and
would be at the greatest risk of air exposure from windblown dust. Outdoor air samples were not
collected as part of this ARR. Wind direction varied throughout the sampling events in August
and was either calm or absent. Although high wind events could transport contaminated particles
from the stormwater retention pond to off-site areas, it was observed the high salt content in the
pond hardens into a micro crust on the soil surface once dry, and this could make particles less
susceptible to wind transport. The majority of other areas on the property are largely covered
with thick vegetation and no waste piles were observed. Human health risk from inhalation
appears to be low.

12.0 DATA QUALITY OBJECTIVES AND ASSESSMENT

Samples were collected and evaluated in accordance with the DERR CERCLA Branch Quality
Assurance Program Plan (DERR 2023b) and relevant EPA guidance documents. A Stage 2B
Data Validation Report includes quality control (QC) laboratory analytical results for all samples
that were analyzed by Chemtech Consulting Group (Appendix F). The Data Validation Report
indicates no samples were qualified as “R” (rejected) and the results may be used as qualified
based on the findings of the validation effort. A Stage 2A Data Validation Report was performed
on samples analyzed by Eurofins Seattle for inorganic arsenic based on a standard level 2 data
package (results and batch QC samples). No rejection or qualification of results was required for
this data package and the results may be used as reported by the laboratory (Appendix F).
Quality assurance (QA) criteria are outlined in the Data Quality Objectives (DQOs) for the Site
(Table 9). The DQOs aimed to determine the extent of elevated arsenic contamination at the Site,
potential sources, and potential risks to human health and the environment. Data from this ARR
suggests that arsenic contamination is limited to the stormwater retention pond and can pose a

Site Inspection Analytical Results Report
26

State Painting – UTN000820797

risk to human health and wildlife, but no definitive point source of pollution has been identified.

The QA/QC samples collected as part of this ARR included field duplicate samples for all
matrices and MS/MSD samples for all matrices. The analytical results for the field duplicate are
compared to the analytical results for the parent field sample to establish the relative percent
difference (RPD) to assess the limits of variability when results are greater than or equal to five
times the practical quantitation limit (reporting limit; RL). Control limits of 20% RPD for water
and 35% RPD for solid matrix samples are common and provide a means to objectively assess
precision (DERR 2023b). RPD is calculated as follows:

RPD = Absolute difference between duplicate results x 100 = %
Mean of duplicate results

If the parent sample and/or the duplicate sample is non-detect, the RPD is typically not
calculated. The validated results that were less than the method detection limit (MDL) were
reported as non-detect at the RL and received a “U” qualifier.

The RPDs for surface water sample SP-SW-11 and field duplicate SP-SW-12 were within the
20% limit except for lead, which was 65% (Table 4). Lead was given a J+ qualifier which
indicates results are estimated and may be biased high (Appendix F). The actual value is
uncertain, which could contribute to the observed variability between the parent and duplicate
samples. The high RPD could be due to surface water samples being highly heterogeneous, and
samples taken from the same location at the same time can have different concentrations of
analytes due to localized variations in water composition, sediment, or particulate matter.
Analytical method limitations could also be a factor; small errors in measurement or sample
preparation can lead to significant differences when the concentrations are low. The percent
recovery criteria for the parent sample and field duplicate SP-SW-11-DSLVD and SP-SW-12-
DSLVD were also not met, and the absolute difference between the two results was greater than
the RL for chromium. These results were qualified as estimated. The RPDs for sediment sample
SP-SE-11 and field duplicate SP-SE-12 were within the 35% limit. (Table 5). The RPDs for soil
sample SP-SO-03 and field duplicate SP-SO-04 were also within the 35% limit (Table 6).

For laboratory QC checks it’s noted the MS for soil sample SP-SO-01 was not within the criteria.
Lead had a negative percent recovery and the manganese percent recovery was above upper
acceptance limits (Appendix F). The MS for sediment sample SP-SE-07 was also not within the
criteria; copper and lead had negative percent recoveries and zinc and manganese parent
recoveries were below lower acceptance limits. The MS for total and dissolved surface water
samples were within the criteria. A MS/MSD was not requested for samples analyzed for

inorganic arsenic (SP-SW-04, SP-SW-06, SP-SE-04, SP-SE-06) because the speciation data is
being used for informational purposes and is not needed for legally defensible purposes. Method
blanks for the samples analyzed by Chemtech Consulting Group were not within the criteria for
several analytes in all matrices; these are described in detail in Appendix F. Method blanks for
solid and water inorganic arsenic analysis were non-detect. All laboratory duplicates and
laboratory control samples/laboratory control sample duplicates were within the criteria for both
analytical methods.
13.0 SUMMARY AND CONCLUSIONS

Investigations from the State Painting Removal Action in May 2018 included surface water and
sediment samples collected from the stormwater retention pond that revealed elevated
concentrations of arsenic. The August 2023 sampling conducted by the DERR was to further
assess the arsenic contamination at the stormwater retention pond, collect additional sampling
throughout the Site to determine the extent and possible migration of arsenic contamination, and
evaluate potential risks to human health and the environment. Key findings are summarized
below:

• Arsenic concentrations in the surface water and sediment from the stormwater retention
pond were elevated, exceeding the aquatic wildlife benchmarks for Utah Standards of
Quality for Waters and the LANL Low Effect ESLs.

• The majority of the arsenic in the surface water and sediment from the stormwater
retention pond was inorganic arsenic, which is more toxic than organic forms.

• Soil samples contained low arsenic concentrations, slightly exceeding the RSL for
Industrial Soil, which is not uncommon for Utah soils.

• The XRF average readings for arsenic closely correlated with corresponding soil sample
results.

• Surface water and sediment samples analyzed from other areas on the Site did not detect
the same magnitude of arsenic contamination that was found at the stormwater retention
pond and indicates no migration of the contamination.

There is no evidence that illegal dumping has occurred at the stormwater retention pond and the
source is likely from urban and rural stormwater runoff transported and accumulated at the pond

over time, or possibly from pesticide and herbicide applications formerly containing arsenic that
may have been used in the pond historically.

Determining the speciation of arsenic in the stormwater retention pond is of value in assessing
risks to human health and the environment because different forms of arsenic have varying
degrees of toxicity. For purposes of this ARR, arsenic speciation was not further characterized
into arsenite (As3+) and arsenate (As5+). The similar concentrations of arsenic in both total and
dissolved surface water results can be due to the alkaline conditions of the water (pH >7) where
arsenic is likely to exist in its more soluble forms, which leads to a larger proportion of arsenic
being present in the dissolved phase rather than bound to particles. Ionic competition from high
concentrations of sodium, potassium, magnesium, and calcium can prevent arsenic from binding
to particles and could also be a factor. The pond may also receive stormwater runoff that may
contain fewer particulates compared to natural bodies of water. The specific hydrochemical
properties of the playa and the overall ionic strength of the water can influence the speciation and
solubility of arsenic.

Although surface water and sediment arsenic concentrations are elevated in the stormwater
retention pond, they are not indicative of a wide-scale release requiring remedial action. The
pond has no outlets, which reduces the likelihood of migration and risk exposure, and the
analytical data indicates there are no other heavily arsenic-contaminated areas at the Site.
Additionally, the stormwater retention pond will not be used for recreation, and no-trespassing
signs will be posted around the pond (WVC Parks and Recreation, personal communication,
April 2, 2023). No further sampling is planned for the Site; however, the DERR recommends
that WVC establish periodic monitoring to ensure public access is limited at the stormwater
retention pond.

Optimization of Sample

During the State Painting
Removal Action, elevated
arsenic was detected in the
surface water and sediments in a
stormwater retention pond west-
adjacent to the State Painting
property. The source of the
arsenic is unknown. The DERR
will collect surface water,
sediments, soil samples, and
XRF field screenings to
determine the extent of elevated
arsenic contamination and
potential risks to human health
and the environment.

West Valley City will be
developing the wetlands
property (the Site) into a
public nature park. Further
evaluation is warranted to
assess if improper disposal of
wastes from the State Painting
site is responsible for the
contamination, if historic use
of agricultural pesticides is a
factor, or if other off-site
sources are contributing to the
arsenic levels found in the
stormwater retention pond.

Analytical data from collected
samples will be used to
determine arsenic
concentrations within the
stormwater retention pond,
wetlands ponds, Riter Canal,
inlet areas, and proposed
gathering areas for the future
park. Arsenic values are likely
to vary throughout the Salt
Lake Valley, but in order to
help determine risk exposure
from the stormwater retention
pond, DERR will request the
laboratory data be analyzed for
inorganic arsenic for the two
surface water and collocated
sediment samples collected at
this location.

The current primary targets are
wildlife receptors that may
reside in or frequent the ponds
and wetlands, the downstream
Riter Canal, workers on the
Site, and the surrounding
residential properties.
Additionally, visitors will be
gathering in numerous areas
throughout the Site when the
park is developed.

If review of the analytical data
determines that the arsenic
concentrations within the West
Valley City wetlands property
poses a threat to human health
and the environment, then the
DERR will consult with the
EPA to determine if further
investigation is warranted.
West Valley City will also be
consulted to determine
appropriate measures to
protect human health at the
property, if needed.
Additionally, data may be
shared with other agencies
involved in the protection of
wetland resources.

Analytical results for surface
water will be compared to
Utah Standards of Quality for
Waters criteria for aquatic
wildlife, sediment results will
be compared to the Los
Alamos National Laboratory
(LANL) benchmarks for
aquatic community organisms
using the Low Effect
Ecological Screening Levels
(ESLs), and soil results will be
compared to EPA’s Regional
Screening Levels for Industrial
Soil to determine the potential
risks, and if further work is
warranted at the Site. The
proximity of the Site to the
mineralized Oquirrh
Mountains will be considered
if variances are observed.

• Review the previous Data
Quality Objectives (DQOs)
step results.
• Develop data collection
design alternatives.
• Select the sample size that
satisfies the DQOs.
• Decide on the most
resource-effective design,
or agreed alternative; and,
• Document details and
decisions made.

Surface water samples,
sediment samples, soil
samples, and XRF field
screenings will be collected as
specified in the SIWP.
Additional opportunity
samples will be collected at the
discretion of the Project
Manager if field conditions
warrant the need for additional
samples. Samples should be
collected while the ponds still
contain water.
Sample locations were selected
based on several factors to
evaluate risk including:
proximity to known arsenic
contamination, proximity to
potential human health and
environmental targets, and
accessibility of the individual
locations.

WEATHER: 1050: Sunny, 79℉, calm wind from the west.

0930: Prior to leaving the office, a Horiba U-50 multi-parameter water quality meter was auto-
calibrated using pH buffer standard 4.01 solution. Due to a torn membrane cap for the dissolved
oxygen (DO) sensor, a scan calibration error for DO was displayed. Sensors were rinsed with
deionized water and recalibrated. A zero-point calibration error was displayed for turbidity.
Because of these errors, the DO and turbidity readings were discarded from the water quality
measurements.
1050: Arrived at the West Valley City wetlands property, Parks & Recreation Maintenance
Building at 2729 South 6750 West. I gave a health and safety briefing on the Site.
1100: Arrived at the sample location for SP-SW-03 and SP-SW-04. West Valley City had a
heavy rain storm on August 3, so there was plenty of water at the Site to sample; however, the
Site's northeast corner was dried up. Since that area was predetermined for surface water samples
SP-SW-05 and SP-SW-06, and sediment samples SP-SE-05 and SP-SE-06, those sample
locations were moved approximately 300 feet southwest where there was enough water to
sample.
1108: I performed water quality measurements with the Horiba at sample location SP-SW-03/04
and entered data on the datasheet and in the Survey123 app. Tom set up equipment for collecting
samples.

1122: Tom collected sample SP-SW-03. I was trying to figure out why I couldn’t enter multiple
samples under the same survey in the Survey123 app; I had to exit the survey and add a new
sample for a new survey each time, and this didn’t seem right to me (it was later discovered that
it was, in fact, right).
1130: A disposable filter was placed on the pump tubing. Tom collected SP-SW-03-DSLVD.
Five mL of nitric acid was added to samples SP-SW-03 and SP-SW-03-DSLVD after collection.
1134: Filter was removed. Tom collected SP-SW-04 (total inorganic arsenic sample). The
container was prefilled with hydrochloric acid by Eurofins lab.
1137-8: Tom collected sediment samples SP-SE-03 and SP-SE-04. A water depth measurement
was taken with a water level gauge where water was collected.
1142: Completed sampling at first location and mobilized to location for SP-SW-05/06. All
samples were stored in an ice cooler. All tubing, disposable gloves, the filter, and the spoon used
to collect sediment samples were disposed of in a garbage bag, and the Horiba, cap, and
collection cup was rinsed with a spray bottle of deionized water.
1214: I performed water quality measurements with the Horiba. Tom collected surface water
samples SP-SW-05 and SP-SW-06 using the same procedures described above. Both samples
were collected unfiltered from the same location; SP-SW-06 was collected for total inorganic
arsenic. I believe SP-SW-05-DSLVD was collected after SP-SW-06, however, this is not how
the time was recorded on the datasheet.
1216: It was documented SP-SW-05-DSLVD was collected, but this time could have been for
SP-SW-06.
1219: It was documented SP-SW-06 was collected, but this time could have been for SP-SW-05-
DSLVD. Five mL of nitric acid was added to samples SP-SW-05 and SP-SW-05-DSLVD after
collection. SP-SW-06 was prefilled with hydrochloric acid by Eurofins lab.
1221: Tom collected sediment samples SP-SE-05 and SP-SE-06. All samples were stored in an
ice cooler. A water depth measurement was taken with a water level gauge where water was
collected. All tubing, disposable gloves, the filter, and the spoon used to collect sediment
samples were disposed of in a garbage bag, and the Horiba was rinsed with a spray bottle of
deionized water.
12:38: Sampling at the Site was completed. All data was recorded on a datasheet and entered into
the Survey123 app. See separate documentation for all data. GPS coordinates and photographs
were taken for all samples.
12:48: Left the West Valley City wetlands property.

DATE: August 9, 2023

FIELD CREW: Robin Keeler and Hannah Tremble-Marty, DERR

WEATHER: 0925: Sunny, 72℉, calm wind from the east/southeast.

0825: Prior to leaving the office, a Horiba U-50 multi-parameter water quality meter was auto-
calibrated using pH buffer standard 4.01 solution. Due to a torn membrane cap for the dissolved
oxygen (DO) sensor, a scan calibration error for DO was displayed.
0925: Arrived at the first location to take an XRF scan for the background soil sample, SP-SO-
05. I gave a health and safety briefing. The XRF was powered on and two system checks were
performed. We used the RCRA sand matrix for the standard test. This was shot # 1197. Arsenic
(As) result was 414 ppm. Standard Deviation was 9.
0945: XRF shot #1198 (background soil sample location). Each shot was held for 120 seconds
per scan and recorded. All data was recorded on a datasheet and entered into the Survey123 app.
See separate documentation for all data and times. All XRF locations were marked with pin
flags, photographed, and GPS coordinates were recorded. It was determined in the field that 30
XRF shots were sufficient to determine the locations of soil samples.
1245-1345: Lunch break and charged cell phone for Survey123 app.
1630: Left site. The plan was to collect surface water samples and XRF soil readings today but
time only allowed for XRF soil readings; therefore, the Horiba was not used.

DATE: August 10, 2023

FIELD CREW: Robin Keeler, Hannah Tremble-Marty (until 1230), and Edoardo Tagliaferri,
DERR

WEATHER: 1019: Sunny, 81℉, wind from the south/southeast.

0836: Prior to leaving the office, a Horiba U-50 multi-parameter water quality meter was auto-
calibrated using pH buffer standard 4.01 solution. Sensors were rinsed with deionized water prior
to calibration. Received a scan calibration error for DO due to the torn membrane cap. Due to
this error, DO readings were discarded from the water quality measurements.
0915: Arrived at the West Valley City wetlands property, Parks & Recreation Maintenance
Building. I gave a health and safety briefing. Gathered equipment and mobilized to surface water
sample location SP-SW-07/-DSLVD.
1019: I collected samples SP-SW-07 and SP-SW-07-DSLVD. Hannah and Edoardo helped with
bottle labeling, preservation, water quality measurements, and entering data on datasheets.
Procedures were followed the same as on 8/7. All data was recorded on a datasheet and entered
into the Survey123 app. See separate documentation for all data and times. All sample locations
were photographed, and GPS coordinates were recorded. All samples were stored in an ice
cooler after collection and water depth was taken for surface water sample locations.
1245-1345: Lunch break and charged cell phone for Survey123 app.

2015: Completed last sample, SP-SE-13. Long day!! 28 samples collected, and also picked up
the majority of pin flags from the XRF locations that were not going to have corresponding soil
samples. Left site.
DATE: August 14, 2023

FIELD CREW: Robin Keeler

WEATHER: 1000: Sunny, 78℉, gentle breeze from the east.

Friday, August 11 was a shorter work day that was spent cleaning up and putting away
equipment from the August 10 sampling, sieving the soil samples, scanning the soil samples in
the clear storage bag with the XRF three times, and creating a spreadsheet to calculate the
average XRF readings. It was not realized until near the end of the work day that I missed
collecting the surface water samples SP-SW-02, SP-SW-02-DSLVD, and corresponding
sediment sample SP-SE-02, so these were collected today.
1000: Arrived at the West Valley City wetlands property, Parks & Recreation Maintenance
Building at 2729 South 6750 West. Gathered equipment and mobilized to sample location.
1009: The drainage area was dry. I collected surface water sample SP-SW-02 right at the mouth
of the culvert where there was still some water left. I did not collect water quality measurements
because there was not enough pH buffer standard 4.01 solution to calibrate the Horiba. I added 5
mL of nitric acid to SP-SW-02 for preservation. All data was recorded on datasheets and in the
Survey123 app. See separate documentation for all data and times. All sample locations were
photographed, and GPS coordinates were recorded.
1017: I placed a disposable filter on the pump tubing and collected SP-SW-02-DSLVD. I added
5 mL of nitric acid to SP-SW-02-DSLVD for preservation.
1021: I collected sediment sample SP-SE-02. A water depth measurement was taken with a
water level gauge where water was collected. All samples were stored in an ice cooler.
I walked the property and collected the rest of the XRF pin flags.
1205: Left site.
1640: Returned to the West Valley City wetlands property. After organizing data at the office, I
realized when collecting the soil samples on August 10, extra soil was not collected for the
MS/MSD and the field duplicate, so I recollected them.
1647: Collected SP-SO-03. (XRF shot #1204.)
1653: Collected the field duplicate, SP-SO-04.
1714: Collected SP-SO-01 and the MS/MSD of SP-SO-01. (XRF shot #1223.)
1736: Left site.

Method blanks:
Within
Criteria Exceedance/Notes
N
The opening continuing calibration blank (CCB009) and closing CCB (CCB010) contained antimony, lead, and zinc at concentrations
greater than the method detection limit (MDL) but less than the reporting limit (identified as the CRQL in the lab report). CCB010
also contained beryllium at a concentration greater than the MDL but less than the reporting limit (RL). The initial calibration blank
analyzed 8/29/2023 also contained zinc between the MDL and RL.
• All antimony and beryllium results were between the MDL and RL; therefore, the sample results were raised to the RL and
qualified as nondetect (flagged U).
• All lead and zinc results were positive detections above the RL and greater than 10 times the concentration of the blank;
therefore, qualifications were not applied.

Interference Check Samples (ICS) (ICP metals only):
Within
Criteria Exceedance/Notes
N
The ICS was assessed because the concentrations of one or more interfering analytes in all samples was greater than or within 80
percent of the concentrations of the interfering analytes in the ICSA.
The ICSA concentrations for arsenic, beryllium, and cobalt were positive and greater than the method detection limit (MDL).
• All beryllium results for were already qualified nondetect due to blank contamination and were not further qualified.
• The results for arsenic and cobalt were greater than ten times the ICSA concentration and were not qualified.
The ICSA concentrations for antimony, cadmium, and vanadium were negative with absolute values greater than the MDL.
• The results for cadmium in samples MH0AA1, MH0AD5, MH0AD6, and MH0AD7 were detected at less than ten times the
absolute ICSA concentration and were qualified as estimated, with possible low bias (flagged J-).
• The results for antimony in all samples were already qualified nondetect due to blank contamination and were further
qualified as estimated (flagged UJ).
• All other results were greater than ten times the absolute ICSA concentrations and were not qualified.

MS/MSDs:
Within
Criteria Exceedance/Notes
N
A matrix spike (MS) was performed on sample MH0AA0. Lead has a negative percent recovery and the manganese percent
recovery was above upper acceptance limits. The parent sample results for the affected analytes were greater than four times the
concentration of the spike; therefore, no qualifications were applied.
While no qualifications were applied, data users should be aware that the matrix spike was not analyzed for aluminum, calcium,
iron, magnesium, potassium, and sodium. These analytes are not required spike analytes by SFAM01.1.

Overall Qualifications:

See results summary pages attached for changes to the laboratory qualifiers based upon this validation. The following is a list of qualifiers and
definitions that may be used for the validation of this data package:

J The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample.
J+ The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased high.
J- The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased low.
NJ The analysis indicates the presence of an analyte that has been “tentatively identified” and the associated value is the approximate
concentration of the analyte in the sample.
R The sample result is rejected as unusable due to serious deficiencies in one or more quality control criteria. The analyte may or may not
be present in the sample.
U The analyte was analyzed for, but was not detected at or above the associated value (reporting limit).
UJ The analyte was analyzed for, but was not detected at or above the associated value (reporting limit), which is considered approximate
due to deficiencies in one or more quality control criteria.

Method blanks:
Within
Criteria Exceedance/Notes
N
Initial calibration blank (LB127047ICB022), continuing calibration blanks (CCB004, CCB005, CCB007, and CCB008), and preparation
blank (PBW006) contained analytes with positive and negative analyte concentrations with absolute values between the method
detection limit (MDL) and reporting limit (identified as CRQL in report). Nondetects and results greater than 10 times the blank
concentration for positive blanks and results greater than 10 times the RL for negative blanks were not qualified. The below table
summarizes the blank results and sample qualifications.
Analyte Contaminated Method Blanks Sample Qualifications
Antimony Positive detections in CCB004, CCB005,
CCB007, and CCB008
Antimony in samples MH0AA6, MH0AA8, MH0AB0, MH0AB2, MH0AB4, MH0AB6, MH0AB8, MH0AC0, and MH0AC2
was detected between the method detection limit (MDL) and reporting limit (RL). The results were raised to the RL
and qualified as nondetect (flagged U). These results were further qualified as estimated (flagged UJ) due to a
negative ICSA result.
Beryllium Positive detections in CCB004, CCB005,
CCB007
Beryllium in sample MH0AB8 was detected between the MDL and RL and was raised to the RL. The result was
qualified as nondetect (flagged U).
Cadmium Negative detections in CCB005, CCB007,
CCB008, LB127047ICB022 Cadmium was nondetect in all samples; therefore, the results were qualified as estimated (flagged UJ).
Calcium
Positive detections in CCB04
Negative detections for CCB007, CCB008
and PBW006
The preparation blank and bracketing CCBs associated with sample MH0AA4 contained negative concentrations of
calcium and the sample result was less than 10 times the RL; therefore, the result was qualified as estimated,
possibly low bias (flagged J-).
Lead Positive detections in CCB004, CCB005, and
CCB007
Lead in samples MH0AA8, MH0AB0, MH0AB2, MH0AB4, and MH0AC2 were detected between the MDL and RL;
therefore, the results were raised to the RL and qualified as nondetect (flagged U).
Lead in samples MH0AA2, MH0AA4, MH0AA6, MH0AB6, MH0AB8, and MH0AC0 were greater than the RL but less
than 10 times the concentration of the blanks; therefore, the results were qualified as estimated, possibly high bias
(flagged J+).
Zinc
Positive detections in CCB005, CCB007,
CCB008, and LB127047ICB022
Negative detections in CCB004 and
PBW006
Samples MH0AA6, MH0AA8, MH0AB0, MH0AB2, MH0AB4, MH0AB6, MH0AB8, MH0AC0, and MH0AC2 had positive
detections between the MDL and RL and were associated with CCBs and preparation blank with negative results;
therefore, the results were qualified as estimated, possibly low bias (flagged J-).
Sample MH0AA2 result had a positive detection above the MDL but less than 10 times the RL. The sample is
associated to a preparation blank with negative results and CCBs with positive results; therefore, the sample result
was qualified as estimated (flagged J).
Samples MH0AA4 result was nondetect. The sample is associated with the preparation blank with negative results
and CCBs with positive results; therefore, the sample result was qualified as estimated (flagged UJ).
Copper,
manganese,
potassium,
silver, and
sodium
Positive detections for copper in CCB008
Positive detections for manganese and
potassium in CCB005, CCB007, and CCB008
Positive detections for silver and
manganese in CCB004
Positive detection for sodium in CCB005
Associated sample results were nondetect or greater than 10 times the concentration of the blanks for the affected
analytes; therefore, no qualifications were applied.

Interference Check Samples (ICS) (ICP metals only):
Within
Criteria Exceedance/Notes
N
The ICS was assessed because the concentrations of one or more interfering analytes in all samples was greater than or within 80
percent of the concentrations of the interfering analytes in the ICSA. The ICS A results for arsenic and beryllium were positive and
greater than the MDL, and antimony, cadmium, and vanadium were negative with an absolute value greater than the MDL. The
following qualifications were applied:
• Cadmium results in all samples were nondetect and qualified as estimated (flagged UJ).
• Antimony results in samples MH0AA6, MH0AA8, MH0AB0, MH0AB2, MH0AB4, MH0AB6, MH0AB8, MH0AC0, and MH0AC2
were qualified nondetect due to blank contamination and were further qualified as estimated (flagged UJ).
• Vanadium in sample MH0AB0 was detected at less than 10 times the ICSA concentration and was qualified as estimated,
with possible low bias (flagged J-).
• Beryllium in sample MH0AB8 was qualified nondetect due to blank contamination; therefore, the result was not further
qualified.
• Results greater than 10 times the absolute ICS A result were not qualified, and nondetected results associated with a
positive ICSA result were not qualified.

Overall Qualifications:

See results summary pages attached for changes to the laboratory qualifiers based upon this validation. The following is a list of qualifiers and
definitions that may be used for the validation of this data package:

J The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample.
J+ The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased high.
J- The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased low.
NJ The analysis indicates the presence of an analyte that has been “tentatively identified” and the associated value is the approximate
concentration of the analyte in the sample.
R The sample result is rejected as unusable due to serious deficiencies in one or more quality control criteria. The analyte may or may not
be present in the sample.
U The analyte was analyzed for, but was not detected at or above the associated value (reporting limit).
UJ The analyte was analyzed for, but was not detected at or above the associated value (reporting limit), which is considered approximate
due to deficiencies in one or more quality control criteria.

Method blanks:
Within
Criteria Exceedance/Notes
N
Initial calibration blank (LB127047ICB022), continuing calibration blanks (CCB004, CCB005, CCB006, CCB007, and CCB008), and
preparation blank (PBW008) contained analytes with positive and negative concentrations with absolute values between the
method detection limit (MDL) and reporting limit (identified as CRQL in report). Nondetects and results greater than 10 times the
blank concentration for positive blanks and results greater than 10 times the reporting limit (RL) for negative blanks were not
qualified. The below table describes blank detections and sample qualifications.
Analyte Contaminated Method Blanks Sample Qualifications
Antimony Positive detections for antimony in CCB004, CCB005,
CCB006, CCB007, and CCB008
Antimony in samples MH0AA7, MH0AA9, MH0AB1, MH0AB3, MH0AB5, MH0AB7, MH0AB9, MH0AC1,
and MH0AC3 were detected at less than the RL. The results were raised to the RL and qualified as
nondetect (flagged U).
Cadmium Negative detections in CCB005, CCB006, CCB007,
CCB008, LB127047ICB022, and PBW008
All sample results for cadmium were nondetect; therefore, the sample results were qualified as
estimated nondetect (flagged UJ).
Calcium
Positive detections in CCB04
Negative detections for CCB006, CCB007, CCB008 and
PBW008
The preparation blank and bracketing CCBs associated with sample MH0AA5 both contained negative
concentrations. The result for sample MH0AA5 was less than 10 times the RL; therefore, the result
was qualified as estimated, possibly low bias (flagged J-).
Lead Positive detections in CCB004, CCB005, CCB006, and
CCB007
The lead results for samples MH0AA3, MH0AA7, MH0AA9, MH0AB1, MH0AB3, MH0AB5, MH0AB7,
MH0AB9, MH0AC1, and MH0AC3 were detected between the MDL and RL. The results were raised to
the RL and qualified as nondetect (flagged U).
Zinc
Positive detections in CCB005, CCB006, CCB007,
CCB008, and LB127047ICB022

Zinc in samples MH0AA7, MH0AA9, MH0AB3, MH0AB7, MH0AB9, and MH0AC1 had positive
detections between the MDL and RL. The samples results were detected between the MDL and RL;
therefore, were raised to the RL and qualified as nondetect (flagged U).
The zinc results for MH0AB5 and MH0AC3 results were greater than the RL but less than 10 times the
concentrations of the blank; therefore, the sample results were qualified as estimated, with possible
high bias (flagged J+).
Antimony,
beryllium
copper,
manganese,
potassium,
silver, and
sodium
Positive detections for beryllium in CCB004, CCB005,
and CCB007
Positive detections for copper in CCB008
Positive detections for manganese in CCB004 and
CCB007
Positive detections for potassium in CCB005, CCB006,
CCB007, and CCB008
Positive detections for silver in CCB004
Positive detection for sodium in CCB005 and CCB006
Associated sample results were nondetect or greater than 10 times the concentration of the blanks
for the affected analytes; therefore, no qualifications were applied.

Interference Check Samples (ICS) (ICP metals only):
Within
Criteria Exceedance/Notes
N
The ICS was assessed because the concentrations of one or more interfering analytes in all samples was greater than or within 80
percent of the concentrations of the interfering analytes in the ICSA. The ICSA results for arsenic and beryllium were positive and
greater than the MDL, and antimony and cadmium were negative with an absolute value greater than the MDL. The following
qualifications were applied:
• Cadmium results in samples MH0AA3, MH0AA5, MH0AA7, MH0AA9, MH0AB1, MH0AB3, MH0AB5, MH0AB7, MH0AB9,
MH0AC1, and MH0AC3 were nondetect and are qualified as estimated (flagged UJ).
• Antimony results in samples MH0AA7, MH0AA9, MH0AB1, MH0AB3, MH0AB5, MH0AB7, MH0AB9, MH0AC1, and MH0AC3
were qualified nondetect due to blank contamination and were further qualified as estimated (flagged UJ).
• Results greater than 10 times the absolute ICS A result were not qualified, and nondetected results associated with a
positive ICSA result were not qualified.

MH0AA3 analyzed 8/25/2023 4:31:00 PM percent relative intensities for terbium and bismuth were outside acceptance criteria.
The associated analytes were reported from a reanalysis with acceptable relative intensities; therefore, no qualifications were
applied.
MH0AA5 analyzed 8/25/2023 4:38:00 PM percent relative intensities for scandium, yttrium, terbium, and bismuth were outside
acceptance criteria. The sample was reanalyzed at a dilution and percent relative intensities for yttrium, terbium, and bismuth
were still outside acceptance criteria. Antimony, arsenic, barium, cadmium, lead, selenium, silver, and thallium results were
reported from sequences with relative intensities that were outside acceptance criteria; therefore, the sample results were
qualified as estimated (flagged J/UJ).

Analyte quantitation and MDLs/RLs:
Within
Criteria Exceedance/Notes
Y
Positive results greater than the MDL but less than the RL were qualified as estimated by the laboratory (flagged J). Results less
than the MDL were reported as non-detect at the RL (flagged U). MDLs and RLs are provided in the attached analytical data table

Overall Qualifications:

See results summary pages attached for changes to the laboratory qualifiers based upon this validation. The following is a list of qualifiers and
definitions that may be used for the validation of this data package:

J The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample.
J+ The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased high.
J- The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased low.
NJ The analysis indicates the presence of an analyte that has been “tentatively identified” and the associated value is the approximate
concentration of the analyte in the sample.
R The sample result is rejected as unusable due to serious deficiencies in one or more quality control criteria. The analyte may or may not
be present in the sample.
U The analyte was analyzed for, but was not detected at or above the associated value (reporting limit).
UJ The analyte was analyzed for, but was not detected at or above the associated value (reporting limit), which is considered approximate
due to deficiencies in one or more quality control criteria.

Method blanks:
Within
Criteria Exceedance/Notes
N
The opening continuing calibration blanks (CCB009, CCB010, and CCB011) contained antimony, lead, and zinc at concentrations
greater than the method detection limit (MDL) but less than the reporting limit (identified as the CRQL in the lab report). CCB009
and CCB011 contained beryllium at concentrations greater than the MDL but less than the reporting limit (RL). The initial
calibration blank analyzed on 8/29/2023 contained zinc between the MDL and RL. Results greater than 10 times the blank
concentration or nondetect were not qualified. The following qualifications were applied:
Antimony and beryllium results for samples MH0AC5, MH0AC6, MH0AC7, MH0AC8, MH0AC9, MH0AD0, MH0AD1, and
MH0AD3 were between the MDL and RL; therefore, the sample results were raised to the RL and qualified as nondetect
(flagged U).
• Antimony in samples MH0AC4, MH0AD2, and MH0AD4 were detected between the MDL and RL; therefore, the sample
results were raised to the RL and qualified as nondetect (flagged U).
• Beryllium in samples MH0AC4, MH0AD2, and MH0AD4 were detected at greater than the RL but less than 10 times the
blank concentration and were qualified as estimated, with possible high bias (flagged J+).
• Lead and zinc sample results were detect at concentrations above the RL and greater than 10 times the concentration of
the associated blank; therefore, qualifications were not applied.

Interference Check Samples (ICS) (ICP metals only):
Within
Criteria Exceedance/Notes
N
The ICS was assessed because the concentrations of one or more interfering analytes in all samples was greater than or within 80
percent of the concentrations of the interfering analytes in the ICSA. Arsenic and beryllium were detected at positive
concentrations, and antimony, cadmium, and vanadium were detected at negative concentrations with absolute values greater
than the MDL. The following results were qualified.
• Beryllium results in samples MH0AC4 and MH0AD2 was detected at less than 10 times the ICSA concentration and was
qualified as estimated, with possible high bias (flagged J+). All other results for beryllium were qualified nondetect due to
blank contamination and were not further qualified.
• Cadmium results in all samples were detected at less than ten times the absolute ICSA value and were qualified as
estimated, with possible low bias (flagged J-).
• Antimony results in all samples were qualified nondetect due to blank contamination and were further qualified as
estimated (flagged UJ).
• Results greater than 10 times the absolute ICS A result were not qualified, and nondetected results associated with a
positive ICSA result were not qualified.

MS/MSDs:
Within
Criteria Exceedance/Notes
N
A matrix spike (MS) was performed on sample MH0AC8. Copper and lead had negative percent recoveries and the parent sample
results were greater than four times the concentration of the spike; therefore, no qualifications were applied. Zinc and manganese
percent recoveries were below lower acceptance limits and results were less than four times the concentration of the spike;
therefore, the parent sample results were qualified as estimated, possibly low bias (flagged J-/UJ).
The data users should be aware that the matrix spike was not analyzed for aluminum, calcium, iron, magnesium, potassium, and
sodium. These analytes are not required spike analytes by SFAM01.1.

Overall Qualifications:

See results summary pages attached for changes to the laboratory qualifiers based upon this validation. The following is a list of qualifiers and
definitions that may be used for the validation of this data package:

J The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample.
J+ The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased high.
J- The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased low.
NJ The analysis indicates the presence of an analyte that has been “tentatively identified” and the associated value is the approximate
concentration of the analyte in the sample.
R The sample result is rejected as unusable due to serious deficiencies in one or more quality control criteria. The analyte may or may not
be present in the sample.
U The analyte was analyzed for, but was not detected at or above the associated value (reporting limit).
UJ The analyte was analyzed for, but was not detected at or above the associated value (reporting limit), which is considered approximate
due to deficiencies in one or more quality control criteria.

INTRODUCTION

This checklist summarizes the Stage 2B validation performed on the subject laboratory report, in accordance with the U.S. Environmental
Protection Agency (EPA) Guidance for Labeling Externally Validated Laboratory Analytical Data for Superfund Use (January 2009). Analytical data
were evaluated in general accordance with the Tetra Tech Programmatic Quality Assurance Project Plan for Region 8 Site Assessment Task
Orders, Revision 3 (March 2023), and the EPA National Functional Guidelines (NFG) for Inorganic Superfund Methods Data Review (November
2020).

OVERALL EVALUATION

No rejection or qualification of results was required for this data package. The results may be used as reported by the laboratory.

Data completeness:
Within
Criteria Exceedance/Notes
N
Arsenic speciation was requested on the chain of custody (COC); however, arsenite (As3+) and arsenate (As5+) were not
individually reported. The client was contacted and stated that only total inorganic arsenic was required for this project.
The electronic data deliverable provided is an outdated Scribe EDD format. Laboratory control sample duplicate (LCSD) was also
not provided in the EDD. The LCSD data can be found in the data package. Revisions were not requested at the time of this
validation effort.

Overall Qualifications:

See results summary pages attached for changes to the laboratory qualifiers based upon this validation. The following is a list of qualifiers and
definitions that may be used for the validation of this data package:

J The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample.
J+ The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased high.
J- The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased low.
NJ The analysis indicates the presence of an analyte that has been “tentatively identified” and the associated value is the approximate
concentration of the analyte in the sample.
R The sample result is rejected as unusable due to serious deficiencies in one or more quality control criteria. The analyte may or may not
be present in the sample.
U The analyte was analyzed for, but was not detected at or above the associated value (reporting limit).
UJ The analyte was analyzed for, but was not detected at or above the associated value (reporting limit), which is considered approximate
due to deficiencies in one or more quality control criteria.
