Re: Remediation and Groundwater Monitoring Report, December 2024
Main Street Service Facility ID: 3000110
45 N Main Street Release ID: OIB
Layton, Utah

Dear Mr. Goble:

Rockwell Solutions, Inc. oversaw high vacuum dual phase extraction (HVDPE) activities for the above-
referenced release from September 3 through November 3, 2024. Four groundwater extraction/
monitoring wells were installed in August 2024 and all thirteen monitoring wells were sampled prior to
beginning remediation activities.

Monitoring/Extraction Well Installation
Prior to remediation activities four additional wells, MW-10, MW-11, MW-12, and MW-13, were
installed to serve as both monitoring and extraction wells. MW-10 was installed inside the former bay of
the service station. Figure 1 shows the locations of the wells.

As in previous investigations, the native soil at the site consists of silt to a depth of approximately five to
seven feet below grade which is underlain by a well-sorted sand layer to a depth of approximately
fourteen to sixteen feet below grade. A silty clay layer is below the sand layer to at least twenty feet
below grade. Boring logs are attached.

The two-inch monitoring wells were installed to a depth of twenty feet with fifteen feet of screen. The
borings were advanced using direct push methodology and the wells were installed in each boring with
sand from the bottom of the boring to approximately one foot above the screen. A bentonite seal was
placed above the sand to one foot below the ground surface. Well protectors were installed around each
well and set with concrete.

The monitoring wells were developed using a disposable bailer. The top of casing of each monitoring
well was surveyed and tied into the existing monitoring well network.

Soil samples were collected continuously at each monitoring well boring in five-foot liners. A portion of
the soil sample from each liner was put in a zip-lock baggie to allow hydrocarbons to volatilize. The air
in the zip lock baggie was then screened with a photoionization detector (PID). The soil sample with the
highest PID reading or the sample from just above the groundwater table was collected for laboratory
analysis. Soil samples were analyzed for MTBE, benzene, toluene, ethylbenzene, and total xylenes

(MBTEXN), and total petroleum hydrocarbons-gasoline range organics (TPH-GRO) using EPA Method
8260 and TPH-diesel range organics (TPH-DRO) using EPA Method 8015.

PID readings were very low or nonexistent in soil from the monitoring well borings. Table 1 shows
historical soil analytical data collected at the site. No hydrocarbons were detected in any of the soil
samples collected on August 19, 2024. Laboratory reports and boring logs/well construction diagrams are
attached.

Pre-Remediation Event Groundwater Monitoring
On August 23, 2024, groundwater samples were collected from all thirteen monitoring wells. Depth to
water was measured at each well. Free product was present in MW-1. Groundwater samples were
collected from the other twelve wells using a disposable bailer. Each groundwater sample was
immediately placed on ice and retained under chain-of-custody documentation until relinquished to the
laboratory.

Groundwater samples were submitted for analysis of MBTEXN and TPH-GRO using EPA Method 8260
and TPH-DRO using EPA Method 8015. Table 2 shows historical groundwater analytical data for the
site. Tier 1 levels were exceeded in samples from monitoring wells MW-10 and MW-12. Laboratory
analytical reports are attached.

CalClean Event
From September 3, 2024 to November 3, 2024, CalClean conducted high vacuum dual phase extraction
(HVDPE), extracting groundwater and vapors from monitoring wells MW-1, MW-8, MW-10, MW-12,
and MW-13.

Groundwater Extraction
The HVDPE system ran continuously during the 60-day event and extracted approximately 74,020
gallons of groundwater. The extracted groundwater was treated and discharged into the sewer system
through an onsite sewer cleanout with authorization from the North Davis Sewer District.

Vapor Extraction
The HVDPE system removed soil vapors in conjunction with the groundwater extraction. Vapor
readings were collected from the field analyzer in the system three times a day and vapor samples were
collected on a weekly basis to monitor hydrocarbon removal. Vapors were destroyed by a thermal
oxidizer unit in the truck. CalClean has prepared an extraction report which calculates, based on the daily
readings and weekly vapor samples, that approximately 6,156 pounds of hydrocarbons were removed
during the 60-day event. Vapor analyses indicated 98% and 75% reductions in benzene and TPH vapors,
respectively, from the initial to the final air samples. The CalClean report is attached.

Post-Remediation Event Groundwater Monitoring
On December 6, 2024, groundwater samples were collected from the nine monitoring wells that were
involved in, or adjacent to, the HVDPE wells. Depth to water was measured. There was no longer
measurable free product in MW-1. Groundwater samples were collected from each well using a
disposable bailer. Each groundwater sample was immediately placed on ice and retained under chain-of-
custody documentation until relinquished to the laboratory.

Remediation and Groundwater Monitoring Report, Sept-Oct 2024, Main Street Service., Facility ID #3000110
3

Groundwater samples were submitted for analysis of MBTEXN and TPH-GRO using EPA Method 8260
and TPH-DRO using EPA Method 8015. The results are included in Table 2 and the analytical reports
are attached.

Results
The five extraction wells showed significant reduction in hydrocarbon concentrations. Measurable free
product was no longer present in MW-1, but the TPH-DRO concentration was very high. Perimeter and
downgradient wells MW-4 and MW-9 showed increases in hydrocarbon concentrations. Figures 2 and 3
are isoconcentration maps showing the approximate areas of dissolved TPH-DRO contamination for the
August 2024 and December 2024 sampling events, respectively. The ISL plume does not show
significant shrinkage, but the interior of the plume appears to have shrunk.

Groundwater Flow
Table 2 lists the top-of-casing elevations and depths to water at the site monitoring wells. Groundwater
monitoring data indicates depth to groundwater is between ten and twelve feet below grade. Groundwater
flow on December 6, 2024, was to the southwest, as shown on Figure 4.

Conclusions and Recommendations
The extraction event appears to have removed much of the center of the plume, but contamination
remains at MW-1. Additional corrective action will be required. Rockwell Solutions recommends
replacing MW-1, as it is an old well and the screen may be compromised. One additional well in the Tier
1 plume area may also be necessary for remediation purposes. Also recommended is installing one or two
wells downgradient of MW-4 to define the extent of contamination. Future groundwater monitoring may
include analysis of TPH-DRO fractionation at key wells.

REVISION
The report being provided is a revision of the original report sent on 9/18/2024.The report (revision 1)is being revised due to
updating the client project name..
Analytical test results meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary
Page unless otherwise noted under the individual analysis.Data qualifiers and/or narrative comments are included to explain any
exceptions,if applicable.
Matrix QC may not be reported if insufficient sample is provided or site-specific QC samples were not submitted.In these
situations,to demonstrate precision and accuracy at a batch level,a LCS/LCSD may be performed,unless otherwise
specified in the method.
Surrogate and/or isotope dilution analyte recoveries (if applicable)which are outside of the QC window are confirmed
unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g.SDWA,NPDES)must comply with the associated agency requirements/permits.
Please note that one or more samples in the following analytical report have exceeded the laboratory recommended holding time
for tedlar bags (3 days).As per client-specific program requirements,associated qualifiers concerning holding time have been
removed.

Analytical test results meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary
Page unless otherwise noted under the individual analysis.Data qualifiers and/or narrative comments are included to explain any
exceptions,if applicable.
·Matrix QC may not be reported if insufficient sample is provided or site-specific QC samples were not submitted.In these
situations,to demonstrate precision and accuracy at a batch level,a LCS/LCSD may be performed,unless otherwise
specified in the method.
·Surrogate and/or isotope dilution analyte recoveries (if applicable)which are outside of the QC window are confirmed
unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g.SDWA,NPDES)must comply with the associated agency requirements/permits.
Please note that one or more samples in the following analytical report have exceeded the laboratory recommended holding time
for tedlar bags (3 days).As per client-specific program requirements,associated qualifiers concerning holding time have been
removed.
Receipt
The sample was received on 9/19/2024 7:30 PM.Unless otherwise noted below,the sample arrived in good condition,and,where
required,properly preserved and on ice.The temperature of the cooler at receipt time was 22.0°C.
Air -GC/MS VOA
Method TO15_PF:Surrogate recovery for the following sample was outside control limits:TOTAL INLET (570-199784-1).

Analytical test results meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary
Page unless otherwise noted under the individual analysis.Data qualifiers and/or narrative comments are included to explain any
exceptions,if applicable.
·Matrix QC may not be reported if insufficient sample is provided or site-specific QC samples were not submitted.In these
situations,to demonstrate precision and accuracy at a batch level,a LCS/LCSD may be performed,unless otherwise
specified in the method.
·Surrogate and/or isotope dilution analyte recoveries (if applicable)which are outside of the QC window are confirmed
unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g.SDWA,NPDES)must comply with the associated agency requirements/permits.
Please note that one or more samples in the following analytical report have exceeded the laboratory recommended holding time
for tedlar bags (3 days).As per client-specific program requirements,associated qualifiers concerning holding time have been
removed.
