SUBJECT: Groundwater Monitoring and Sub-Slab Vapor Sampling Work Plan and Price
Work Assignment FQU-15-KLE
Former Jack’s Auto
606 West Center Street
Midvale, Utah
Dear Ms. Coe:
Kleinfelder is pleased to submit this Work Plan and Price for environmental services at the former
Jack’s Auto facility located at 606 West Center Street in Midvale, Utah (Site). Kleinfelder received
work assignment FQU-15-KLE from the Utah Department of Environmental Quality (UDEQ) Division
of Environmental Response and Remediation (DERR) on November 26, 2024, which requested that
Kleinfelder prepare a Work Plan and Price to conduct a groundwater monitoring well survey and
groundwater monitoring at the Site. Additionally, the work assignment requested that Kleinfelder
arrange access agreements and complete sub-slab vapor sampling at potentially affected residences
in the Site vicinity.
BACKGROUND AND SITE DESCRIPTION
The Site owners formerly operated four underground storage tanks (USTs). In 1991, the four USTs
were removed from the Site. In 1989 and 1990, UST removal subsurface investigation work was
conducted at the west adjacent former Handimart property. Petroleum releases affecting soil and
groundwater at the two properties were reported to the UDEQ in 1991 and 1992. Sometime after
1991, a soil vapor extraction (SVE) system was installed at the former Handimart property.
From 1993 through the present-day, additional groundwater monitoring wells, piezometers, and
soil borings were advanced at the Site and nearby properties to assess the two releases. Light
non-aqueous phase liquid (LNAPL), up to 6.6 feet thick, was observed in several groundwater
monitoring wells and piezometers. In 1995, a LNAPL recovery system was installed at the Site. The
LNAPL recovery system was only operated for approximately one month due to limited LNAPL
recharge and recovery. Following shutdown of the LNAPL recovery system, bailing was the primary
method used for LNAPL recovery.

In general, groundwater across the Site ranges from approximately 30 to 48 feet below ground
surface (bgs). The groundwater flow direction is generally towards the west-northwest. Soils at the
Site generally consist of silty clay underlain by alternating layers of silt, sand, and gravel to the
maximum depth explored (approximately 50 feet bgs).
SCOPE OF SERVICES
Our scope of services is based on our conversations with you on 14 November 2024 regarding the
work completed in April 2023 under work assignment FQU-14-KLE, and the tasks described in Work
Assignment FQU-15-KLE.
Task 1 – Groundwater Monitoring Well Survey
Prior to conducting work at the Site, Kleinfelder will update the Health and Safety Plan (HASP) for
the project. The HASP will include project and emergency contact information, descriptions of
project hazards, required personal protective equipment, and maps to a clinic and hospital.
Psomas, under the supervision of Kleinfelder field personnel, will survey the 25 existing monitoring
wells at the Site (see Figure 1). Psomas will provide the location and top of casing elevation for each
monitoring well. The survey will be completed in the State Plane coordinate system with
Latitude/Longitude locations provided. The elevations will be collected using the North American
Vertical Datum of 1988 (NAVD88) and will be referenced to an existing survey monument near the
Site.
Task 2 – Groundwater Monitoring
All 25 monitoring wells on Site will be measured to gauge depth to LNAPL and groundwater as well
as total depth. Of the 25 monitoring wells on Site, 16 are proposed for monitoring. Four of those
16 groundwater monitoring wells were dry in April 2023 and are not proposed for sampling during
this event. If enough groundwater is measured in one or more of the four previously dry wells,
Kleinfelder will contact the DERR for approval to sample the monitoring wells. A list of wells
proposed for monitoring is shown in Table 1. Total well depths were recorded during the April 2023
monitoring event.

*below top of casing
Following gauging activities, one groundwater sample will be collected from each of the twelve
groundwater monitoring wells proposed for sampling in Table 1. Prior to sample collection, each well
will be purged of three casing volumes of groundwater using a new, factory-sealed, weighted,
disposable bailer and allowed to recover to at least 80 percent of the static water level. Samples will
not be collected from wells with measurable LNAPL. Groundwater purged from wells during
sampling activities will be spread across the paved ground surface and allowed to evaporate if
measurable LNAPL is not observed.
The samples will be decanted into appropriate containers, labeled, stored on ice, and transported
under chain-of-custody documentation to Pace National Center for Testing and Innovation (Pace) in
Mt Juliet, Tennessee (a Utah certified analytical laboratory) for analysis. The groundwater samples
(including
two blind duplicates) will be analyzed for methyl tertiary-butyl ether (MTBE), benzene, toluene,
ethylbenzene, total xylenes, and naphthalene (MBTEXN) and total petroleum hydrocarbons (TPH) as
gasoline range organics (GRO) by EPA Method 8260 and TPH as diesel range organics (DRO) by EPA
Method 8015. Additionally, one trip blank will accompany the groundwater samples to the
laboratory and will be submitted for analysis of volatile organic compounds by EPA Method 8260.
Task 3 – Groundwater Monitoring Report
Groundwater monitoring data obtained during our investigation will be reviewed, evaluated, and a
report will be prepared documenting the results of the monitoring activities. The report will include
a summary of the field methods used, field observations, figures, and analytical results compared to
DERR ISLs, DERR Tier 1 Screening Criteria, and EPA RSLs, as appropriate. Kleinfelder will also include
updated historical data tables for the Site. One electronic copy of the report will be provided to
DERR no later than ten business days following the receipt of all analytical results.
This task will also include the generation of two geologic cross sections for the Site to help better
understand the subsurface lithologies and how they may be impacting groundwater conditions and
LNAPL migration at the Site. Based on previous reports, no cross sections have been made for the
Site to explain the groundwater high point that is roughly centered on MW-17. A better
understanding of the subsurface would provide important information for future remedial actions

KLEINFELDER 849 West Levoy Drive, Suite 200 Salt Lake City, UT 84123-2964 p | 801.261.3336
at the Site. In addition to the cross sections, this task will include previous hydrographs showing
historical LNAPL thickness at the Site. This information will allow for a better understanding of
where the subsurface may be most impacted and aid in any future remedial actions at the Site.
Task 4 – Access Agreements for Sub-Slab Vapor Sampling
Kleinfelder proposes to collect sub-slab vapor samples from four residential properties located
above or near the LNAPL plume. Figure 1 (included as Attachment A) shows the LNAPL plume as
observed in April 2023. Based on our interpretation of the lateral extent of the LNAPL plume at the
Site, we recommend the collection of sub-slab vapor samples from four residential structures
located at the following addresses:
•7673 Allen Street,
•7692 Allen Street,
•640 West Center Street, and
•648 West Center Street.
Kleinfelder will work to obtain access agreements with the property owners of the four above-listed
residential properties. Based on our experience with businesses and residents in the Site vicinity,
we anticipate the need for English to Spanish translation services. A Kleinfelder employee will work
with the four property owners to explain the scope of work and terms of the agreements.
Kleinfelder will use the DERR’s standard access agreement form. If it becomes necessary to
translate the access agreements into Spanish (or any other language), Kleinfelder will need the
UDEQ to provide Kleinfelder the translated document. Kleinfelder assumes that UDEQ personnel
will be available to meet with private property owners if they are unwilling to meet with Kleinfelder
or sign the access agreements.
Task 5 – Sub-Slab Vapor Sampling
Prior to installing the soil vapor monitoring points (SVMPs), Kleinfelder will contact Utah BlueStakes
to clear public utilities on the Site. Penhall, under the supervision of Kleinfelder, will conduct a
private utility locate at each of the four proposed soil vapor monitoring points. A Kleinfelder
representative will be on-site during the utility clearance activities.
Following the utility locate, Kleinfelder will use an AMS Sub-Slab Vapor Probe Installation Kit with a
slide hammer or rotary hammer drill to install four soil vapor monitoring points at the Site. At each
of the four SVMP locations, a six-inch vapor monitoring point will be installed at approximately
8.5-9 ft below ground surface (bgs). This sampling depth assumes that each residence has a
basement and that the foundation slab is approximately eight feet bgs. If this is not the case, the
SVMPs may be installed at a more appropriate depth. The data from these probes will help
characterize the risk of vapor intrusion at the four residential properties. Each piece of equipment
will be decontaminated with a Liquinox® solution between each location. The vapor points will be
installed in locations with the highest likelihood of impacts or where each property owner allows

them to be installed. To minimize impacts to the private residences, the preferred locations for
SVMP installation will be near the foundation along the exterior of each residence.
After the SVMPs have been installed and allowed to stabilize for 24 hours, Kleinfelder will collect a
vapor sample from each location. Sampling will begin by purging three vapor point volumes of air
using a Landtec GEM 5000 Gas Analyzer. Purge start and end time as well as initial and final
readings for methane, oxygen, and carbon dioxide will be recorded prior to sample collection. Pri or
to sample collection, a “shut-in” test will be performed at each sampling point to ensure that the
sampling chain does not leak. During sample collection, helium will be used as a tracer gas to
evaluate the extent of atmospheric air intrusion, if any. Samples will be collected using the negative
pressure of each 1-liter SUMMA canister and with a 100 milliliter per minute flow controller
attached. Initial and final vacuum pressures will be recorded for each SUMMA Canister. Each
sample will be shipped under proper Chain of Custody documentation to Pace National Laboratory
in Mt. Juliet Tennessee for analysis of volatile organic compounds (VOCs) and total petroleum
hydrocarbons – gasoline range organics (TPH-GRO) via Environmental Protection Agency (EPA)
Method TO-15. Results will be compared against screening levels from the Environmental
Protection Agency Regional Screening Levels (EPA RSLs). Samples will be analyzed under standard
turnaround time which is typically 10 days after the samples are received.
Task 6 – Sub-Slab Vapor Monitoring Report
Soil vapor data obtained during our investigation will be reviewed, evaluated, and a report will be
prepared documenting the results of the monitoring activities. The report will include a summary of
the field methods used, field observations, figures, and analytical results compared to EPA RSLs.
Kleinfelder will also include updated historical data tables for the Site. One electronic copy of the
report will be provided to DERR no later than ten business days following the receipt of all analytical
results.
ESTIMATED PROJECT FEE
A detailed cost itemization for each task described above is presented as Attachment B. The
estimated costs to complete the work described above are $31,785.80. The work will be performed,
and payment for completed tasks will be made, according to the terms and conditions of our
existing Master Services Contract #216378.
ASSUMPTIONS
Our proposed scope of services is based on the following assumptions:
•MW-25 will not be surveyed, gauged, or sampled since benzene, TPH-GRO, and TPH-DRO
concentrations were not reported by the laboratory during the December 2022
groundwater monitoring event. MW-25 is located in the left turn lane in Center Street and
would require a permit from the City of Midvale and traffic control to temporarily close the
turn lane.

KLEINFELDER 849 West Levoy Drive, Suite 200 Salt Lake City, UT 84123-2964 p | 801.261.3336
•MW-9, MW-10, MW-14, and MW-18 will not be sampled since they were dry during the
April 2023 monitoring event. If enough groundwater is measured in one or more of the four
previously dry wells, Kleinfelder will contact the DERR to secure additional funds for sample
collection and laboratory analysis.
•All wells will be accessible and in adequate condition for sample collection and no well
development will be required to collect representative samples.
•The monitoring well survey can be completed in one 5-hour field half-day.
•The groundwater gauging and sampling activities can be completed in three ten-hour field
days.
•Utility locating activities can be completed in one 5-hour field half-day.
•The sub-slab vapor monitoring point installation and subsequent vapor sampling can be
completed in a total of three ten-hour field days.
•Kleinfelder does not need access agreements with private property owners to sample and
purge groundwater monitoring wells.
•Purged groundwater will be spread on a non-permeable surface and allowed to evaporate.
No costs have been included in this Workplan and Price for investigation derived waste
groundwater storage, characterization, or disposal.
•One electronic copy of the report shall be forwarded to DERR. No hard copies are included
in our scope of services. Client meetings, revisions, and any work following the submittal of
the report are not included in the budget estimate but can be provided on a time-and-
materials basis.
•Samples submitted for laboratory analysis will be conducted on a standard turnaround time.
No rush fees are included in our proposal.
•Subcontractor fees will be marked up 10 percent.
•Kleinfelder may not be able to secure the four access agreements for the residential
properties with the budget included in this Workplan and Price. In this case, the scope may
need to be modified (fewer or different sample locations), or an additional fee may be
required to continue efforts to obtain legal access to the properties proposed for vapor
sampling.
LIMITATIONS
Our work will be performed in a manner consistent with that level of care and skill ordinarily
exercised by other members of Kleinfelder’s profession practicing in the same locality, under
similar conditions and at the date the services are provided. Our conclusions, opinions, and
recommendations will be based on a limited number of observations and data. It is possible that
conditions could vary between or beyond the data evaluated. Kleinfelder makes no guarantee or
warranty, express or implied, regarding the services, communication (oral or written), report,
opinion, or instrument of service provided.

The Client should be aware that penetrating the ground surface is inherently risky and it is
impossible to determine with certainty the precise location of all utilities and/or structures that may
be buried in the ground. Kleinfelder's fee is not adequate to compensate for both the performance
of the services and the assumption of risk of damage to such structures or encountering
obstructions from buried debris in the fill covering the site. Although Kleinfelder will make all
reasonable effort to avoid damage to utilities, disruption of utilities or damage to underground
structures will be the responsibility of the Client. Services rendered by Kleinfelder to repair them
will be billed at cost.
During the course of the performance of Kleinfelder's services, hazardous materials may be
discovered. Kleinfelder will assume no responsibility or liability whatsoever for any claim, loss of
property value, damage, or injury that results from pre-existing hazardous materials being
encountered or present on the project site, or from the discovery of such hazardous materials.
AUTHORIZATION
If our proposed scope of services and fee meet your needs, please provide a Work Assignment for
the activities discussed herein.
CLOSURE
We appreciate the opportunity to submit this Work Plan and Price and look forward to continuing
to work with you on this project. If you have any questions concerning this document, please
