RE: Site Inspection Analytical Results Report
900 South 200 West Solvents
SEMS EPA ID UTN000821040
Dear Mr. Dunham:
Enclosed for your review is a Site Inspection (SI) Analytical Results Report (ARR) for 900
South 200 West Solvents (SEMS EPA ID UTN000821040) (herein referred to as “Site”) located in
Salt Lake City, Salt Lake County, Utah.
This investigation was initiated due to the detection of chlorinated solvents in soil,
groundwater, indoor air, and soil gas at the Site since 1999. These chlorinated solvents include:
Tetrachloroethene (PCE),
Trichloroethene (TCE),
1,1-dichloroethene (1,1-DCE),
cis-1,2-dichlorethene (cis-1,2-DCE),
trans-1,2-dichloroethene (trans-1,2-DCE), and
vinyl chloride (VC).
These substances, known nervous system depressants, were found at concentrations
exceeding the U.S. Environmental Protection Agency’s (EPA) benchmark concentrations, posing
potential risks to human health and the environment. The Utah Department of Environmental
Quality, Division of Environmental Response and Remediation (DERR), completed a Preliminary
Assessment in May 2021, followed by this SI to further evaluate potential risks.
Page 2
Key findings in the SIARR are:
Groundwater: PCE, TCE, DCE, and VC were detected at levels exceeding the EPA
Tapwater Screening Levels and/or Maximum Contaminant Levels. However, the nearest
municipal well (1.8 miles away) and the closest non-monitoring well (1,000 feet away)
are both outside the contaminant plume, making groundwater exposure unlikely.
Soil Gas: PCE and TCE were detected at levels exceeding the EPA Vapor Intrusion
Screening Levels for commercial use, primarily near the former dry-cleaner site.
However, the design of the adjacent Slate Apartments, with residential areas positioned
away from the source zone, minimizes potential exposure. The absence of chlorinated
solvents in down-gradient locations further suggests minimal risk of vapor intrusion into
occupied spaces.
For these reasons, the DERR recommends a No Further Remedial Action Planned for this
Site.
Thank you for your attention to this matter. If you have any questions, please contact me at
(385) 391-8147 or etagliaferri@utah.gov.

SUMMARY:
The purpose of this site visit was to perform soil gas and groundwater sampling in the public
ways northwest of the site, in accordance with the 900s 200w Site Inspection Work Plan
(February 2023, Sandlin), to delineate current plume boundaries and assess the risk that soil
vapor intrusion poses to properties downgradient of the site.
- On Monday 10/23 Rudi, Swistak, and I met with Thompson to perform the private utility-
locate on each of the eight future boring locations. Blue Stakes were scheduled for 8am,
but some showed up later that day (electricity, phone, google fiber, gas) and sewer/water
the next day, though Rudi stayed on-site to wait for them until 16:00.
- On Tuesday 10/24 Rudi, Swistak and I were joined by the rest of the Tetratech crew.
Tom from the city located sewer/water utilities. Cleared for drilling, a safety meeting was
conducted and we began soil gas boring, purging, and collection of samples. Throughout
the day, all 8 soil gas samples were collected. After the first was bored to 6’ bgs per the
work plan, the second hit refusal at 5’bgs; the decision was then made to bore all
remaining soil gas holes to 5’bgs, for time, continuity between samples, and 5’bgs being
standard in other samplings. SG-05 was re-sampled because while performing the first
sample, the pressure rose to -5mmHg faster than the prescribed hour. All soil gas borings
were patched. Sampling was attempted on an existing monitoring well but pushed to the
next day due to overly slow flow speed from bladder pump, excessive well drawdown,
and time constraints.
- On Wednesday 10/25 the full Tetratech team and I continued sampling. SG-03 was
redone due to the initial pressure being -19.9 mmHg instead of -25 mmHg, and was
patched afterwards. Three of the four temporary monitoring wells were drilled today;
MW-08 was postponed until the car above it had moved. The new borings and existing
monitoring wells were scanned with a photoionization detector (PID) for worker safety;
low-flow sampling & purging methods were used with a GeoTech GeoPump peristaltic
pump, and water quality parameters were measured in five-minute intervals until stable
using a YSI multi-parameter reader. For the samples, water was drawn into the tubing,
the pump was stopped, the tubing was pulled out of the well, and the flow was reversed
to fill the sampling vial. Due to high turbidity and sediment in the water column of the
temporary wells, no temporary wells were sampled this day, and the decision was made
to let them sit overnight, protected by duct tape, a vinyl glove, and a cone. All the
existing monitoring wells were sampled today, using the same methods. Daniels joined
briefly to walk the site and see the sampling in action.
- On Thursday 10/26 the full Tetratech team (minus Ellen) and I continued sampling. MW-
08 was unoccupied by the car and was bored. All four temporary monitoring wells
achieved stabilization quickly and were sampled, and subsequently patched. An end-of-
work meeting was held, we ensured all work had been completed, and departed the site.
On Tuesday Kevin Higgs from Granite Environmental, the contractor who made the new road
construction for the city over the past three years, was passing by the site on other business and
told us there was a box culvert that was not marked by the city nor private locator, passing within
the marked private locate marked box; when we re-drilled SG-03 on Wednesday refusal was hit
at 3 feet, seeming to confirm the presence of the box culvert (SG-03 was successfully re-redrilled
one foot north).
After the bladder pump was not able to pump water out at an acceptable rate to take the
parameters/samples, the idea of using a peristaltic pump was posed to Ryan Dunham; the
concern with using the peristaltic was that Tetratech thought that VOC’s might be stripped from
the water when going through the pump. After Dunham’s approval, the peristaltic pump was
used, with the main deviation from general practice that we reversed the pump so that the water
being sampled was never going through the pump. Eisman believed this last edition would make
for more accurate results.
Throughout the week, the types of blanks to use were discussed. Because a lab did not
supply the sampling vials to Tetratech and they put together their own kit, they made their own
trip blanks in the field at the site. These served as trip blanks. After conversation we added a
temperature blank before they sent the samples to the lab.
During planning maps and tables were revised, and therefore there was some confusion
on which maps and sample points to use. The main clarification that I needed to make was which
samples were to be field duplicates, and which were to be MS/MSDs. The field duplicate for
groundwater was taken at MW-107M, and the field duplicate for soil gas was taken at SG-05.
The MS/MSD was taken at MW-101.

Dear Mr. Dunham:
Tetra Tech, Inc. (Tetra Tech) is pleased to submit the following letter report for the 900 South 200 West Solvents
Site in Salt Lake City, Salt Lake County, Utah. The Superfund Technical Assessment and Response Team
(START) assisted the U.S. Environmental Protection Agency (EPA) and Utah Department of Environmental
Quality(UDEQ) with assessment activities at the site from October 24 through 26, 2023. Enclosure 1 provides
figures that depict the site location and sample locations. Enclosure 2 provides three tables that summarize the
sampling and analytical results. Enclosure 3 provides the photographic log. Enclosure 4 provides the data
validation report. Enclosure 5 contains the laboratory data packages. Enclosure 6 contains scanned copies of field
notes.
SITE DESCRIPTION AND BACKGROUND
The site is located on 900 South between the intersections of 200 West and 300 West in Salt Lake City, Salt
Lake County, Utah (Figure 1 in Enclosure 1). The approximate center of the site is located at
40.7494047, -111.896997. The site includes multiple parcels, including one which contained a now demolished
dry cleaning facility (the Facility) at 906 South 200 West. The Facility hosted dry cleaning operations from 1920
to 2015 when Henrie’s Dry Cleaners, the most recent occupant, closed (UDEQ 2023).
The site is located in a mixed-use area, with residential developments bordering the Facility to the south and
southwest. There are various restaurants, residential units, and small businesses in the area. A Utah Transit
Authority TRAX rail line and passenger station is at the intersection of 900 South and 200 West.
Two underground storage tanks (USTs) containing a dry-cleaning solvent mixture (Stoddard solvent) and an oil-

water separator were previously used at the Facility. In 1990, the USTs were removed after they were found to
be leaking, and impacted soil was removed in 1992 (UDEQ 2023).
In a 1992 report published by Sitex Environmental, Inc., minor residual ethylbenzene and xylene contamination
was found after the soil removal clean-up efforts (UDEQ 2023).
In a 1999 Phase II Subsurface Investigation, Granite Environmental, Inc. found tetrachloroethene (PCE) at a
concentration of 300 micrograms per kilogram (µg/kg) in a soil sample from the Facility. Since then, multiple
environmental investigations have identified chlorinated solvents in soil, groundwater, and soil gas at
concentrations exceeding EPA Regional Screening Levels (RSLs), Maximum Contaminant Levels (MCLs), and
Vapor Intrusion Screening Levels (VISLs). These contaminants include PCE, trichloroethene (TCE), 1,1-
dichloroethene (1,1-DCE), cis-1,2-dichloroethene (cis-1,2-DCE), trans-1,2-dichloroethene, and vinyl chloride
(UDEQ 2023).
Two source areas for chlorinated solvent contamination were located—one near the northwest corner of the
Facility associated with the Stoddard solvent UST basin, and one near the west-central portion of the Facility
associated with a drum storage area and dry-cleaning equipment (UDEQ 2023).
In 2021, the Utah Division of Waste Management and Radiation Control approved a Corrective Action Plan
(CAP) and Baseline Risk Assessment and Work Plan for the Facility in an effort to remediate contamination and
reduce migration from the site. Since beginning remediation efforts, follow-up soil sampling events have shown
that contaminants at the two source areas are at lower concentrations than residential RSLs (UDEQ 2023).
A Preliminary Assessment in 2021 by the Utah Division of Environmental Response and Remediation for 900
South 200 West states that chlorinated solvents have migrated from the Facility to nearby adjacent properties.
The boundaries of the current plume are unknown (UDEQ 2023).
FIELD ACTIVITIES
START conducted field activities at the site from October 24 through 26, 2023 based on a work plan prepared by
UDEQ. Figure 2 in Enclosure 1 depicts the site features and sampling locations associated with the site. Prior to
field activities, START arranged subsurface utility clearance through Blue Stakes of Utah and Ground
Penetrating Radar Systems (GPRS). UDEQ obtained necessary access agreement and worked with START on
site to provide guidance for sampling. The following subsections provide a description of the field activities and
samples collected.
Soil Gas Sampling
Between October 24 and 25, 2023, soil gas implants were installed at eight locations chosen by UDEQ using
direct-push technology (DPT) to advance push rods to a depth of 5 feet below ground surface (bgs) (Figure 2).
The rods were pulled up approximately 1 foot out of the boring and a stainless-steel implant attached to 0.25-
inch-diameter Teflon tubing was inserted in each rod. There was no need for hydrated granular bentonite to
create a tight seal because the rod was tightly sealed in the borehole and the sample was being pulled directly
from a port at the bottom of the rod. Each soil gas sample was collected using a batch-certified, 1-liter Summa
canister affixed with a flow controller calibrated to collect a sample over an approximately 1-hour period.
Starting times and vacuum pressures were recorded along with Summa canister and flow controller serial
numbers for each sample. A field duplicate sample pair was collected with both Summa canisters affixed with
flow controllers that connected to a common sampling port using a stainless-steel sampling “T” provided by the
laboratory. Ending times and vacuum pressures were recorded after samples were collected (see Table 1 in
Enclosure 2). No refusal was encountered during this field sampling event.
Soil gas samples were shipped under chain of custody via FedEx to ALS Environmental (Simi Valley,
California) for analysis of volatile organic compounds (VOCs) using EPA Method TO-15. Table 2 in Enclosure
2 summarizes the analytes detected in soil gas samples. Enclosure 5 contains a copy of the laboratory data
package.
Groundwater Sampling
From October 24 through 26, 2023, START collected six groundwater samples and one duplicate sample from
an existing network of permanent monitoring wells (MW-100, MW-100M, MW-101, MW-105M, MW-105S,
and MW-107M) and four groundwater samples from temporary monitoring wells (MW-02, MW-05, MW-06,
and MW-08) (Figure 2). Temporary monitoring wells were installed using DPT to advance borings to a total
depth of 15 feet bgs at each location. Equipment was then removed from the hole, and a 10-foot-long slotted,
schedule 40 polyvinyl chloride (PVC) screen with 5 feet of riser (solid casing) above was installed in each well.
There were no apparent visual or olfactory indications of contamination observed during the soil borehole
logging process.
Samples were collected from each well using a peristaltic pump with 0.25-inch-diameter Teflon tubing.
Groundwater monitoring wells were purged until groundwater parameters stabilized.
Groundwater samples were shipped under chain-of-custody via FedEx to Bonner Analytical Testing Co.
(Hattiesburg, Mississippi) for analysis of VOCs using EPA Method 8260D under the EPA Contract Laboratory
Program (CLP). Analytical results can be found in Table 3 in Enclosure 2. Enclosure 5 contains a copy of the
CLP data package.
DEVIATIONS FROM SCOPE OF WORK
The scope of work initially called for soil gas samples to be collected at a depth 6 feet bgs but was changed to 5
feet bgs by UDEQ in the field based on time constraints.
Two groundwater and four soil gas sampling locations were moved based on proximity to marked utilities. SG-
04 was moved approximately 40 feet west across Washington Street to the southwest corner of 900 South and
Washington Street. SG-07 and MW-08 were moved to approximately 50 feet south from their originally
proposed locations. SG-03 was moved approximately 90 feet northwest to the median parking area in the center
of 900 South between 200 West and Washington Street because of the thickness of concrete in the originally
proposed location. MW-05 and SG-05 were also moved approximately 90 feet toward the corner of Washington
Street and 900 South.
The work plan prepared by UDEQ called for daily collection of field blanks, and the preparation of trip blanks
before departure to the field (UDEQ 2023). However, trip blank samples were not prepared before the sampling
event and instead were prepared on site. Trip blanks are typically prepared prior to the sampling event rather than
on site so that the trip blanks accompany the sample containers to the site. UDEQ confirmed that collecting the
trip blank samples in the field fulfilled the requirement of daily collection of field blanks; however, these field
blanks were identified as trip blanks for laboratory purposes.
The four temporary groundwater wells were sampled on October 26 after and during a mixed snow and rain
precipitation event. The PVC well openings were covered, in addition to cones being placed over the pavement
openings, on October 25 prior to leaving the site in anticipation of the precipitation. In case any precipitation had
entered the wells, the top of the water column in the well was purged for approximately 10 minutes prior to
beginning parameter collection.
The YSI water quality meter was first calibrated on October 24, 2023; however, conductivity could not be
calibrated on this date because of a possible instrument malfunction, and insufficient standard solution remained
to calibrate the instrument a second time. Calibration was achieved for all other parameters on October 24, 2023.
Monitoring wells were also sampled on October 25 and 26, 2023; however, the YSI meter could not be
calibrated for any parameters on those days because of an insufficient quantity of standard solutions.
The work plan prepared by UDEQ called for collection of 20 groundwater field samples, 10 soil gas field
samples, 2 groundwater field duplicates, 4 trip blanks, and two matrix spike (MS) / matrix spike duplicate pairs.
Only 11 groundwater field samples (including one field duplicate), 9 soil gas field samples (including one field
duplicate), 2 trip blanks, and one MS/MSD were collected. The changes were caused by the reduction in the
number of field samples by UDEQ prior to sampling event. Only one MS/MSD sampling location was needed,
and the MS/MSD was collected from well MW-101. The reductions in field samples, field duplicates, trip
blanks, and MS/MSD samples were all approved by UDEQ.
DECONTAMINATION AND INVESTIGATION-DERIVED WASTE
All sampling equipment sample was disposable, was removed from the site, and disposed of as non-hazardous
waste.
DATA VALIDATION
START conducted a Stage 2B data validation of the laboratory analytical results in accordance with the Tetra
Tech Quality Assurance Project Plan for Region 8 Site Assessment Task Orders, Superfund Technical
Assessment and Response Team, EPA Region 8 (Tetra Tech 2023) and EPA National Functional Guidelines for
Superfund Organic Methods Data Review (EPA 2020). A review of quality control samples and methods is
included in the data validation reports. Enclosure 4 provides the data validation reports. Enclosure 5 provides
copies of the laboratory analytical data packages.
RESULTS
Various analytes were detected in both soil gas and groundwater samples at concentrations exceeding screening
levels. Tables 2 and 3 in Enclosure 2 contain a summary of analyte detections and exceedances in both matrices.
VOCs 1,3-butadiene, benzene, chloroform, PCE, and TCE were all detected at concentrations exceeding the
screening level in one or more soil gas samples. Several other analytes were not detected in any sample, but the
laboratory reporting limit exceeded the screening level in one or more samples.
VOCs 1,1-DCE, benzene, cis-1,2-DCE, ethylbenzene, PCE, TCE, and vinyl chloride were detected at
concentrations exceeding a screening level in one or more groundwater samples. Several other analytes were not
detected in any sample, but the laboratory reporting limit exceeded a screening level in one or more samples.
