WORK PLAN FOR REPLACEMENT MONITORING WELL INSTALLATION
THE BEVERLY
63 SOUTH 600 WEST
SALT LAKE CITY, UTAH
1. INTRODUCTION
On behalf of C.W. Land, the owner of The Beverly (Facility), Wasatch Environmental, Inc., (Wasatch) has
prepared this work plan for Replacement Monitoring Well Installation to continue evaluating the residual
chlorinated solvent impacts to groundwater following remediation activities at the Facility.
1.1 Facility Description
The Facility has recently been redeveloped as a residential apartment complex located at 63 South 600
West, in Salt Lake City, Utah as depicted on Figure 1. The Facility occupies a single 0.90-acre parcel
(Parcel Number 15-01-105-007). The Facility is surrounded by mixed commercial and residential land
use. A Facility vicinity map is presented as Figure 2.
1.2 Facility Background
Under the regulatory oversight of the Utah Department of Environmental Quality, Division of Waste
Management and Radiation Control (DWMRC), an environmental response project, as defined in Section
57-25-102(5) of the Utah Code Annotated, approved by the DWMRC for The Beverly, has been
undertaken to address a release, prior to owner’s purchase of the real property on which The Beverly is
located. Soil and shallow groundwater of chlorinated solvents and/or semi-volatile organic compounds
(SVOCs) that likely originated from former occupants of the buildings were removed in 2019, which
included American Barrel (at least 1970s to 1980s) and Myers Container (1990s).
The Owner purchased The Beverly on July 30, 2019. During November 2019, the former buildings
located on the Facility were removed. During demolition and slab removal activities, and under the
direction and approval of the DWMRC, numerous soil characterization samples were collected beneath
features where releases to the subsurface could have potentially occurred. These areas included
oil/water separators, trench floor drains, pits, underground piping, and a former waste management area.
Soil samples were analyzed for volatile organic compounds (VOCs) and SVOCs.
Based on the analytical results from the investigation activities, two areas of SVOC -impacted soil at
concentrations that exceeded U.S. Environmental Protection Agency (EPA) Regional Screening Levels
(RSLs) for Residential Soil were identified. In January 2020, two excavations were completed in the
areas of SVOC impacts. Soil confirmation samples were collected from each excavation and no VOCs or
SVOCs were detected in the soil confirmation samples at concentrations exceeding their respective U.S.
EPA RSLs for Residential Soil.
Based on analytical results from previous subsurface investigations conducted at the Facility, it appeared
that a small tetrachloroethene (PCE) plume with concentrations exceeding its U.S. EPA federal Maximum
Contaminant Level (MCL) was present beneath the southern portion of the Facility.
Wasatch supervised the installation of five groundwater monitoring wells MW-1 through MW-5 at the
Facility in January 2021 and May 2021 (see Figure 3). The first round of groundwater monitoring
activities was conducted on the Facility in May 2021. Based on the analytical results, the groundwater
sample (MW-1) collected near the western property boundary exhibited concentrations of PCE at 110
micrograms per liter (µg/L) and trichloroethene (TCE) at 5.54 µg/L, both of which exceed their U.S. EPA
MCL of 5 µg/L. The second round of groundwater monitoring activities was conducted in October 2021.
The analytical results were consistent with those previously reported, as the groundwater sample
collected from monitoring well MW-1 exhibited concentrations of PCE and TCE and 105 µg/L and 6.11
µg/L, respectively.

Based on the depth to groundwater measurements, the groundwater flow direction is to the west.
Given the groundwater data, it appeared that the groundwater impacts originate from the southern portion
of the Facility and may be migrating off-site. Based on the results of the groundwater sampling, Wasatch
recommended the installation of an additional monitoring well off-site to the west to evaluate if significant
chlorinated solvent impacts to groundwater are migrating off-site.
In April 2022, Wasatch supervised the installation of off-site monitoring well MW-6 (see Figure 3). The
analytical results indicate that TCE was detected in the groundwater sample collected from monitoring
well MW-6 at a concentration of 1.4 µg/L, below its U.S. EPA MCL of 5 µg/L. PCE was detected in the
groundwater sample collected from monitoring well MW-6 at a concentration of 12.2 µg/L, which slightly
exceeded its U.S. EPA MCL of 5 µg/L; however, it was Wasatch’s opinion that this off-site concentration
was not significant enough to warrant further off-site investigation. Additionally, these concentrations
were significantly lower than previous concentrations detected in the groundwater samples collected from
monitoring well MW-1 located along the western edge of the Facility.
During the December 2023 sampling event, monitoring MW-1 well could not be located. According to
C.W. Land personnel, a bench was inadvertently installed on top of monitoring well MW -1. Pursuant to
conversation with Utah DWMRC personnel, Wasatch has prepared this work plan to install a replacement
monitoring well in the area former monitoring well MW-1.
1.3 Objective
The objective of the monitoring well installation is to install a replacement monitoring well at the western
Facility boundary so that future groundwater monitoring events can continue to evaluate chlorinated
solvent impacts to groundwater at the hydraulically downgradient Facility boundary.
2. GROUNDWATER MONITORING WELL INSTALLATION ACTIVITIES
PCE has been identified at concentrations exceeding its U.S. EPA federal MCL within the groundwater
beneath the Facility near the west and hydraulically downgradient boundary of the Facility. Previously
installed monitoring well, MW-1, located at the western and hydraulically downgradient Facility boundary
is no longer assessable due to a bench being installed over the monitoring well. Therefore, Wasatch
proposes installing a replacement monitoring well (MW-1R) in the public right-of-way near the location of
former monitoring well MW-1 so that long-term groundwater monitoring at the Facility can continue to be
further evaluated as part of the Site Management Plan (SMP) that was approved by the Utah DWMRC.
The monitoring well will be installed using direct-push techniques with a GeoProbe 7822 drill rig.
Wasatch proposes installing the monitoring well as depicted on Figure 3.
Prior to installation of the monitoring well, Wasatch will obtain the necessary permits and traffic control
plan from the City of Salt Lake.
The monitoring well will consist of 2-inch inner-diameter (I.D.) polyvinyl chloride (PVC) casing with 10-
foot, 0.010-slot, pre-packed sand screen. The monitoring well surface completion will be flush mount.
Based on depth-to-groundwater at the Facility, Wasatch anticipates the total depth of the monitoring well
will be approximately 15 to 25 feet below ground surface.
Subsequent to monitoring well installation, the monitoring well will be developed to remove fines from the
well screen using a peristaltic pump. The monitoring well top-of-casing elevation will be surveyed to
within 0.01-foot using an on-site benchmark (MW-3) assigned an arbitrary value of 100.00 feet above
mean sea level.
Once groundwater monitoring well installation activities are completed, Wasatch will deploy a
HydraSleeve no-purge sampler in monitoring well MW-1R in preparation for the next sampling event.

3. WASTE CHARACTERIZATION SAMPLING AND ANALYSIS
Wasatch anticipates generating a small quantity of groundwater waste during the groundwater monitoring
well development activities. Groundwater generated during monitoring well development activities will be
properly stored, labeled, characterized, transported, and disposed.
4. HEALTH AND SAFETY
All groundwater monitoring well installation and monitoring activities at the Facility would be performed by
Wasatch in accordance with Wasatch’s general health and safety policy. A site-specific health and safety
plan has previously been prepared to address specific health and safety concerns and establish protocols
for conducting work related activities in a safe manner.
5. PROJECT SCHEDULE
Wasatch proposes completing the monitoring well installation activities in early to mid-2024. Ongoing
monitoring well sampling activities will be completed subsequent to monitoring well installation and are
scheduled for October 2024.
