EXECUTIVE SUMMARY
The Trindale Mini Mart site is an active convenience store and gasoline retail facility located at 7619 NC
Highway 62 in Trinity, Randolph County, North Carolina. The site is covered by concrete and asphalt. The
surrounding area consists of a mixture of residential, institutional, and commercial properties. One 3,000-
gallon kerosene, one 3,000-gallon gasoline, and one 4,000-gallon gasoline USTs were closed on April 27,
1990. One 7,000-gallon fuel oil UST was closed on July 31, 1990. One 3,000-gallon kerosene UST was
closed on August 1, 2016. Three 8,000-gallon gasoline USTs and associated pumps and product piping are
active at the site.

On August 1, 2016, one 3,000-gallon kerosene UST, associated dispenser and product piping were
removed from the site. Soil samples collected during the UST closure activities contained contaminant
concentrations that exceeded the soil-to-water MCCs, confirming the presence of a release at the site and
a LSA was required.

A receptor survey was conducted on April 25, 2017, during which eleven water supply wells were
identified within a 1,500-foot radius of the site. All residences with identified water supply wells were
connected to municipal water. No water supply wells were identified within a 250-foot radius of the
source area. No surface water bodies were identified within 500 feet of the source area. Public water is
available to the site and the surrounding properties.

One Type II monitoring well (MW-1) was installed during the LSA conducted at the site in April 2017. A
free product thickness of 0.10 feet was measured in MW-1 subsequent to installation. Well MW-1 was
again gauged on September 5, 2020, and 5.91 feet of free product was measured. Two 8-hour AFVR
events have been conducted on MW-1 to recover free product. On April 22, 2020, four additional Type II
monitoring wells (MW-2 through MW-5) were installed around the UST basin, to delineate free product.
Based on the results of the LSA and additional assessment activities, a CSA was required.

Between August 17 and August 19, 2021, five Type II monitoring wells (MW-6 through MW-10) and one
Type III telescoping well (TW-1) were installed as part of the CSA activities. The MACs were below
contaminant concentrations of benzene, MTBE, naphthalene, tert-amyl alcohol, tert-butyl alcohol, 1,2-
dichloroethane, di-isopropyl ether, 1-methylnaphthalene, 2-methylnaphthalene, C5-C8 aliphatics, C9-C12
aliphatics, C9-C10 aromatics, C9-C18 aliphatics and/or C11-C22 aromatics reported in the ground water
samples collected from MW-7, MW-8, MW-9, and TW-1. The GCL was below the MTBE concentration
reported in the ground water sample collected from MW-7. Free product was measured in MW-1, MW-
3, and MW-6 with thicknesses of 0.66, 0.03 and 0.01 feet, respectively.

Based on observations made during assessment activities, surficial soils observed at the site consist of
clayey to sandy silt and silty clay to depths of approximately 65 feet BGS. There appears to be a ground
water trough oriented toward the northeast and centered around the UST basin. The horizontal hydraulic
gradient was convergent from the southeast and northwest with gradients of approximately 0.04 feet per
foot. There is a general ground water flow trend toward the north-northeast. The vertical hydraulic

iii
gradient calculated for paired wells MW-4/TW-1 was approximate 0.05 feet per foot in the upward
direction.

Rising head slug tests were conducted on MW-8, MW-9, and TW-1. The average hydraulic conductivity
calculated for the Type II monitoring wells was 1.449 x 10-3 feet per minute (2.086 feet per day) and the
average seepage velocity was 4.17 x 10-1 feet per day (152 feet per year). The hydraulic conductivity
calculated for the Type III monitoring well was 1.015 x 10-2 feet per minute (14.62 feet per day). The
seepage velocity calculated for the Type III monitoring well was 2.34 feet per day (854 feet per year).

The site risk classification has been deemed as intermediate risk based on the presence of free product
and/or GCL exceedances. Therefore, free product must be removed from the site and the ground water
contamination must be remediated to concentrations less than the GCLs.

Free product removal should continue at the site until free product is no longer present. A ground water
sampling event should be conducted at the site in February 2022 to confirm the results of the CSA ground
water sampling events. Based on the results of the February 2022 sampling event, a decision to pursue
corrective action or allow for natural attenuation can be made.

1.0 SITE HISTORY AND CHARACTERIZATION
GRI presents the results of the August 2021 CSA activities at the Trindale Mini Mart site; located at 7619
NC Highway 62 (Trindale Road) at the intersection with Sealy Drive in Trinity, Randolph County, North
Carolina (Figure 1). These activities were conducted in accordance with GRI Proposal No. 20-459, which
was submitted to the NCDEQ on September 23, 2020, and was approved as Task Authorization No. 44719-
09 on October 2, 2020. A change order was submitted for this proposal to include a DEQ well permit. The
change order was submitted to the NCDEQ on July 20, 2021 and was approved as Task Authorization No.
44719-09-1 on July 26, 2021. State correspondence has been included as Appendix A.

The site is currently owned by Joan S. Angel and is operated by Angels, Inc. Tindale Mini Mart as a
petroleum retail facility. A release was discovered in August 2016 during the removal of a 3,000-gallon
kerosene UST at the site. One 3,000-gallon kerosene, one 3,000-gallon gasoline, and one 4,000-gallon
gasoline USTs were closed on April 27, 1990. One 7,000-gallon fuel oil UST was closed on July 31, 1990.
Three 8,000-gallon gasoline USTs and associated pumps and product piping are active at the site. UST
owner/operator information and UST system information are included as Tables 1 and 2, respectively.
The Registered Tank Report is shown below:

On August 1, 2016, one 3,000-gallon kerosene UST was removed from the site. Soil samples collected
during the UST closure activities contained contaminant concentrations that exceeded the soil-to-water
MCCs. The UST closure results confirmed a release at the site and a LSA was required by the NCDEQ.

On April 26, 2017, one monitoring well (MW-1) was installed in the area of the former 3,000-gallon
kerosene UST basin. Two soil samples were collected during the installation of monitoring well MW-1.
The reported contaminant concentrations of several analyzed contaminants exceeded the soil-to-water
MCCs and/or the residential SCLs for the submitted soil samples. Subsequent to installation, free product
was measured in MW-1 with a thickness of 0.10 feet; therefore, the well was not sampled. Two AFVR
events have been conducted on MW-1 to recover free product.

On April 22, 2020, four additional Type II monitoring wells (MW-2 through MW-5) were installed in order
to delineate the free product plume. All on-site monitoring wells were gauged, purged and/or sampled.
Free product was observed in monitoring wells MW-1 and MW-3 with free product thicknesses of 0.64
feet and 0.03 feet, respectively. The MACs were exceeded by several analyzed contaminants in the
ground water samples collected from MW-2, MW-4 and MW-5. Based on the results of the LSA activities,
the site was assigned an intermediate risk classification and a CSA was required by the NCDEQ.

In August 2021, a CSA was conducted in order to delineate the horizontal and vertical extent of the
petroleum contamination. Between August 17 and August 24, 2021, five additional Type II monitoring
wells (MW-6 through MW-10) and one Type III telescoping monitoring well (TW-1) were installed, gauged
and/or sampled as part of the CSA activities. The MACs were below contaminant concentrations of
benzene, MTBE, naphthalene, tert-amyl alcohol, tert-butyl alcohol, 1,2-dichloroethane, di-isopropyl
ether, 1-methylnaphthalene, 2-methylnaphthalene, C5-C8 aliphatics, C9-C12 aliphatics, C9-C10 aromatics,
C9-C18 aliphatics and/or C11-C22 aromatics reported in the ground water samples collected from MW-7,
MW-8, MW-9, and TW-1. The GCL was below the MTBE concentration reported in the ground water
sample collected from MW-7. Free product was measured in MW-1, MW-3, and MW-6 with thicknesses
of 0.66, 0.03 and 0.01 feet, respectively. Therefore, MW-1, MW-3 and MW-6 were not sampled. Slug
tests were performed on MW-8, MW-9, and TW-1 at the site on August 24, 2021. A Site Map showing the
locations of the monitoring wells and the structures on-site has been included as Figure 2. A copy of the
site-specific Health and Safety Plan has been included as Appendix B.

On April 22, 2020, four additional Type II monitoring wells (MW-2 through MW-5) were installed on the
site to delineate free product. All on-site monitoring wells were subsequently gauged, purged and/or
sampled. Free product was observed in monitoring wells MW-1 and MW-3 with free product thicknesses
of 0.64 feet and 0.03 feet, respectively; therefore, those wells were not sampled. The MACs were below
the concentrations of benzene, MTBE, naphthalene, TAA, p-isopropyltoluene, n-propylbenzene, 1,2,4-
trimethylbenzene, methyl chloride, 1,2-dichloroethane, 1-methylnaphthalene, 2-methylnaphthalene, C5-
C8 aliphatics, C9-C12 aliphatics, C9-C10 aromatics, C9-C18 aliphatics, and/or C11-C22 aromatics reported
in the ground water samples collected from MW-2, MW-4 and MW-5. None of the contaminant
concentrations were above the GCLs. Based on the results of the LSA activities, a CSA was required by the
NCDEQ.

Between August 17 and August 19, 2021, five additional Type II monitoring wells (MW-6 through MW-10)
and one telescoping monitoring well (TW-1) were installed at the site. Monitoring wells MW-6 through
MW-10 were drilled to total depths ranging from 30 to 35 feet and were all completed with 20-foot
screened intervals. Telescoping well TW-1 was completed to a total depth of 65 feet with a five-foot
screen interval. Well photos have been included in Appendix C.

On August 24, 2021, monitoring wells MW-1 through MW-10 and TW-1 were gauged. Only the newly
installed monitoring wells (MW-6 through MW-10 and TW-1) were purged and sampled. The Macs were
below the concentrations of benzene, MTBE, naphthalene, tert-amyl alcohol, tert-butyl alcohol, 1,2-
dichloroethane, di-isopropyl ether, 1-methylnaphthalene, 2-methylnaphthalene, C5-C8 aliphatics, C9-C12
aliphatics, C9-C10 aromatics, C9-C18 aliphatics and/or C11-C22 aromatics reported in the ground water
samples collected from MW-7, MW-8, MW-9 and TW-1. The GCL was below the MTBE concentration
reported in the ground water sample collected from MW-7. Free product was measured in MW-1, MW-
3 and MW-6 with free product thicknesses of 0.66, 0.03 and 0.01 feet, respectively, and therefore were
not sampled. Please note that monitoring wells MW-2 and MW-4 were gauged in order to determine
ground water flow for the site, and were not sampled as part of the CSA activities. A summary of the

6.0 FREE PRODUCT INVESTIGATION AND RECOVERY
Free product has historically been present in MW-1, MW-3 and MW-6. On August 16, 2017, two free
product evaluations were conducted on monitoring well MW-1. A free product thickness of 5.91 feet was
measured in MW-1 prior to the tests. Approximately 2 gallons of free product was hand bailed from MW-
1 prior to the start of Test #1. Due to equipment error, Test #1 was stopped after one hour. Test #2 was
started approximately 2 hours following the conclusion of Test #1 and lasted approximately 1.5 hours.
Approximately 2 gallons of free product were bailed from MW-1 before Test #2. Prior to Test #2, free
product was first measured at a thickness of 1.85 feet at the start of the event and achieved a measurable
thickness of 2.12 feet by the end of the 90-minute evaluation. A summary of the free product evaluation
and test has been provided in Table 8 with recovery graphs included as Appendix F.

Two 8-hour AFVR events were conducted on monitoring well MW-1 to recover free product in August
2017 and February 2019. A combined total of approximately 1,176 gallons of petroleum impacted ground
water was removed during these events. At the conclusion of these events, no free product was measured
in MW-1 or in the tanker. Summaries of the free product removal results and costs have been included
as Tables 9 through 11. Based on the results of the AFVR event, AFVR appears to be a cost effective
method of free product removal.

7.0 HYDROGEOLOGIC INVESTIGATION
The depths to ground water in the Type II monitoring wells (MW-1 through MW-10) measured on August
24, 2021, ranged from 18.56 to 25.43 feet below the tops of well casings. Ground water elevations at the
site, based on an assumed datum of 100 feet, ranged from 74.73 to 77.43 feet relative to a temporary
benchmark. Based on this information, there appears to be a ground water trough oriented toward the
northeast and centered around the UST basin. The horizontal hydraulic gradient was convergent from
the southeast and northwest with gradients of approximately 0.04 feet per foot. There is a general ground
water flow trend toward the north-northeast. The vertical hydraulic gradient calculated for paired wells
MW-4/TW-1 was approximate 0.05 feet per foot in the upward direction. A summary of ground water

elevation data obtained during assessment activities to date is presented in Table 12. A Water Table
Surface Map based on the August 24, 2021, gauging data is included as Figure 12.

Rising head slug tests were conducted in MW-8, MW-9 and TW-1 on August 24, 2021. Hydraulic
conductivities in the Type II monitoring wells calculated using the Bouwer and Rice method, ranged from
1.389 x 10-4 feet per minute (0.200 feet per day) to 2.759 x 10-3 feet per minute (3.973 feet per day). The
average hydraulic conductivity was 1.449 x 10-3 feet per minute (2.086 feet per day). Seepage velocities,
calculated using the equation V = k(dh/dl)/ne, ranged from 4.00 x 10-2 to 7.95 x 10-1 feet per day (14.6 to
290 feet per year). The average seepage velocity was 4.17 x 10-1 feet per day (152 feet per year). The
hydraulic conductivity in the Type III monitoring well calculated using the Bouwer and Rice method was
1.015 x 10-2 feet per minute (14.62 feet per day). The seepage velocity calculated for the Type III
monitoring well was 2.34 feet per day (854 feet per year). A summary of the results of slug test analyses
is presented in Table 13. Calculations and raw data from the slug tests have been included as Appendix
G.

8.0 REGIONAL GEOLOGY AND HYDROGEOLOGY
According to the 1985 Geologic Map of North Carolina, the site is in the Carolina Slate Belt within the
Piedmont Physiographic Provence of North Carolina. The rocks underlaying the site are primarily
metamorphosed foliated granitic rocks
9.0 SITE GEOLOGY AND HYDROGEOLOGY
Based on observations made during assessment activities, surficial soils observed at the site consist of
clayey to sandy silt and silty clay to depths of approximately 65 feet BGS. A summary of the August 2021
ground water gauging data is shown below:

identified a release from the UST system.

To date, ten Type II monitoring wells and one telescoping well have been installed to determine the
horizontal and vertical extent of the release. Free product has been observed in the vicinity of the UST
basin in monitoring wells MW-1, MW-3 and MW-6. Monitoring well MW-7 contained the highest ground
water contamination levels during the CSA activities with the GCL below the reported concentration of
MTBE. Please note that MW-7 is also in the vicinity of the UST basin. Based on the current risk ranking of
the site, it was determined that the contaminant plume remains undefined both horizontally and
vertically.

The risk ranking for the site has been established as intermediate due to the presence of free product and
GCL exceedances. In order to lower the risk ranking of the site, free product recovery should continue at
the site until free product is no longer present and ground water concentrations are below GCLs.
11.0 CONCLUSIONS AND RECOMMENDATIONS
 Ground water flow direction is to the north.
 The ground water contaminant plume remains undefined vertically, as well as horizontally to the
north, east and west at the site; however, the NCDEQ Incident Manager has determined it to be
sufficiently delineated for the site specific cleanup goals.
 Based on this site assessment, the site risk classification should remain intermediate.
 Free product removal should continue until free product is no longer present and ground water
concentrations are below GCLs.
 GRI recommends additional assessment be conducted at the site in order to adequately define
the free product and GCL plume. AFVR events should continue at the site for wells containing
free product and GCL exceedances. Comprehensive ground water sampling should be conducted
at the site in February 2022. Based on the results of the February 2022 sampling event, further
recommendations can be made.

Re: Notice of Regulatory Requirements 15A NCAC 2L .0407(c) Risk-based Assessment and Corrective Action for Petroleum Underground Storage Tanks Trindale Mini Mart 7619 NC Highway 62 Trinity, Randolph County Incident Number: 44719 Risk Classification: Intermediate Ranking: I232D
Dear Mr. Angel:
The Limited Site Assessment Report received by the UST Section, Division of Waste Management, Winston-Salem Regional Office on June 26, 2017 and a Groundwater Monitoring Report received on June 4, 2020 have been reviewed. The risk posed by the discharge or release at the subject site is classified by
the Department of Environmental Quality as intermediate, as stipulated under Title 15A NCAC 2L .0406. The land use at the site is classified as industrial/commercial. Title 15A NCAC 2L .0407(a) requires you to notify the Department of any changes that might affect the risk or land use classifications that have been assigned. Title 15A NCAC 2L .0407(c) requires you to comply with assessment and cleanup requirements of Title 15A NCAC 2N .0706 and Title15A NCAC 2L .0106(c) and 2L .0106(g). A Comprehensive Site Assessment (CSA) Report prepared in accordance with these requirements and the most recent version of the Guidelines for Assessment and Corrective Action for UST Releases must be received by this office within 90 days of the date of this notice. In addition, you must submit a summary of the CSA Report to the local Health Director and the local Chief Administrative Officer in accordance with 15A NCAC 2L .0114. The summary should be submitted to these persons no later than five working days after submittal of the CSA Report to this office. Failure to comply in the manner and time specified, may result in the assessment of civil penalties and /or the use of other enforcement mechanisms.
Effective October 1, 2004, the Department requires that all work following the submittal of the Limited Site Assessment Report (Title 15A NCAC 2L .0405) be preapproved if State Trust Fund reimbursement is
anticipated. To comply with this requirement, a completed Preapproval/Claim Authorization Form,

encompassing the required remedial activities, must be received in this office within 14 days of the date of this letter. Upon completion of the preapproved activities, you should submit your claim promptly. Reimbursement funds are budgeted based on completed preapprovals, but lengthy delays in reimbursement
can occur if claims are not submitted immediately following work completion. Because a release or discharge has been confirmed, a Licensed Geologist or a Professional Engineer,
certified by the State of North Carolina, is required to prepare and certify all reports submitted to the Department in accordance with Title 15A NCAC 2L .0103(e) and 2L .0111(b).
If you have any questions regarding trust fund eligibility or reimbursement from the Commercial or Noncommercial Leaking Petroleum Underground Storage Tank Cleanup Funds, please contact the UST Section Trust Fund Branch at [phone]. If you have any questions regarding the actions that must be taken or the rules mentioned in this letter, please contact me at the address or telephone number listed below. Sincerely,
Doug Whitmire, PG Hydrogeologist

EXECUTIVE SUMMARY
The Trindale Mini Mart site is an active convenience store and gasoline retail facility located at 7619 NC
Highway 62 in Trinity, Randolph County, North Carolina. The site is covered by concrete and asphalt. The
surrounding area consists of a mixture of residential, institutional, and commercial properties. One 3,000-
gallon kerosene, one 3,000-gallon gasoline, and one 4,000-gallon gasoline USTs were closed on April 27,
1990. One 7,000-gallon fuel oil UST was closed on July 31, 1990. One 3,000-gallon kerosene UST was
closed on August 1, 2016. Three 8,000-gallon gasoline USTs and associated pumps and product piping are
active at the site.

On August 1, 2016, one 3,000-gallon kerosene UST, associated dispenser and product piping were
removed from the site. Soil samples collected during the UST closure activities contained contaminant
concentrations that exceeded the soil-to-water MCCs, confirming the presence of a release at the site and
a LSA was required.

A receptor survey was conducted on April 25, 2017, during which eleven water supply wells were
identified within a 1,500-foot radius of the site. All residences with identified water supply wells were
connected to municipal water. No water supply wells were identified within a 250-foot radius of the
source area. No surface water bodies were identified within 500 feet of the source area. Public water is
available to the site and the surrounding properties.

One Type II monitoring well (MW-1) was installed during the LSA conducted at the site in April 2017. A
free product thickness of 0.10 feet was measured in MW-1 subsequent to installation. Well MW-1 was
again gauged on September 5, 2020, and 5.91 feet of free product was measured. Two 8-hour AFVR
events have been conducted on MW-1 to recover free product. On April 22, 2020, four additional Type II
monitoring wells (MW-2 through MW-5) were installed around the UST basin, to delineate free product.
Based on the results of the LSA and additional assessment activities, a CSA was required.

Between August 17 and August 19, 2021, five Type II monitoring wells (MW-6 through MW-10) and one
Type III telescoping well (TW-1) were installed as part of the CSA activities. The MACs were below
contaminant concentrations of benzene, MTBE, naphthalene, tert-amyl alcohol, tert-butyl alcohol, 1,2-
dichloroethane, di-isopropyl ether, 1-methylnaphthalene, 2-methylnaphthalene, C5-C8 aliphatics, C9-C12
aliphatics, C9-C10 aromatics, C9-C18 aliphatics and/or C11-C22 aromatics reported in the ground water
samples collected from MW-7, MW-8, MW-9, and TW-1. The GCL was below the MTBE concentration
reported in the ground water sample collected from MW-7. Free product was measured in MW-1, MW-
3, and MW-6 with thicknesses of 0.66, 0.03 and 0.01 feet, respectively.

Based on observations made during assessment activities, surficial soils observed at the site consist of
clayey to sandy silt and silty clay to depths of approximately 65 feet BGS. There appears to be a ground
water trough oriented toward the northeast and centered around the UST basin. The horizontal hydraulic
gradient was convergent from the southeast and northwest with gradients of approximately 0.04 feet per
foot. There is a general ground water flow trend toward the north-northeast. The vertical hydraulic

gradient calculated for paired wells MW-4/TW-1 was approximate 0.05 feet per foot in the upward
direction.

Rising head slug tests were conducted on MW-8, MW-9, and TW-1. The average hydraulic conductivity
calculated for the Type II monitoring wells was 1.449 x 10-3 feet per minute (2.086 feet per day) and the
average seepage velocity was 4.17 x 10-1 feet per day (152 feet per year). The hydraulic conductivity
calculated for the Type III monitoring well was 1.015 x 10-2 feet per minute (14.62 feet per day). The
seepage velocity calculated for the Type III monitoring well was 2.34 feet per day (854 feet per year).

The site risk classification has been deemed as intermediate risk based on the presence of free product
and/or GCL exceedances. Therefore, free product must be removed from the site and the ground water
contamination must be remediated to concentrations less than the GCLs.

Free product removal should continue at the site until free product is no longer present. A ground water
sampling event should be conducted at the site in February 2022 to confirm the results of the CSA ground
water sampling events. Based on the results of the February 2022 sampling event, a decision to pursue
corrective action or allow for natural attenuation can be made.

RE: Comprehensive Site Assessment – Public Notice
Trindale Mini Mart
7619 NC Highway 62
Trinity, North Carolina
Randolph County
Incident Number: 44719
GRI Project Number: 4236

Dear Ms. Aker:

In August 2016, a petroleum release was reported at the above referenced property. In conjunction
with the North Carolina Department of Environmental Quality (NCDEQ), soil and ground water
assessment activities, including Phase I Limited Site Assessment (LSA) and Comprehensive Site
Assessment (CSA), were conducted at the site.

Please find enclosed a copy of the executive summary and pertinent figures and tables associated with
the CSA Report for the above referenced site in accordance with the public notice requirements listed
15A NCAC 2L .0114 of the Guidelines for Assessment and Corrective Action published by the UST Section
of NCDEQ.

Please do not hesitate to contact the undersigned at [phone] if you have any questions or

EXECUTIVE SUMMARY
The Trindale Mini Mart site is an active convenience store and gasoline retail facility located at 7619 NC
Highway 62 in Trinity, Randolph County, North Carolina. The site is covered by concrete and asphalt. The
surrounding area consists of a mixture of residential, institutional, and commercial properties. One 3,000-
gallon kerosene, one 3,000-gallon gasoline, and one 4,000-gallon gasoline USTs were closed on April 27,
1990. One 7,000-gallon fuel oil UST was closed on July 31, 1990. One 3,000-gallon kerosene UST was
closed on August 1, 2016. Three 8,000-gallon gasoline USTs and associated pumps and product piping are
active at the site.

On August 1, 2016, one 3,000-gallon kerosene UST, associated dispenser and product piping were
removed from the site. Soil samples collected during the UST closure activities contained contaminant
concentrations that exceeded the soil-to-water MCCs, confirming the presence of a release at the site and
a LSA was required.

A receptor survey was conducted on April 25, 2017, during which eleven water supply wells were
identified within a 1,500-foot radius of the site. All residences with identified water supply wells were
connected to municipal water. No water supply wells were identified within a 250-foot radius of the
source area. No surface water bodies were identified within 500 feet of the source area. Public water is
available to the site and the surrounding properties.

One Type II monitoring well (MW-1) was installed during the LSA conducted at the site in April 2017. A
free product thickness of 0.10 feet was measured in MW-1 subsequent to installation. Well MW-1 was
again gauged on September 5, 2020, and 5.91 feet of free product was measured. Two 8-hour AFVR
events have been conducted on MW-1 to recover free product. On April 22, 2020, four additional Type II
monitoring wells (MW-2 through MW-5) were installed around the UST basin, to delineate free product.
Based on the results of the LSA and additional assessment activities, a CSA was required.

Between August 17 and August 19, 2021, five Type II monitoring wells (MW-6 through MW-10) and one
Type III telescoping well (TW-1) were installed as part of the CSA activities. The MACs were below
contaminant concentrations of benzene, MTBE, naphthalene, tert-amyl alcohol, tert-butyl alcohol, 1,2-
dichloroethane, di-isopropyl ether, 1-methylnaphthalene, 2-methylnaphthalene, C5-C8 aliphatics, C9-C12
aliphatics, C9-C10 aromatics, C9-C18 aliphatics and/or C11-C22 aromatics reported in the ground water
samples collected from MW-7, MW-8, MW-9, and TW-1. The GCL was below the MTBE concentration
reported in the ground water sample collected from MW-7. Free product was measured in MW-1, MW-
3, and MW-6 with thicknesses of 0.66, 0.03 and 0.01 feet, respectively.

Based on observations made during assessment activities, surficial soils observed at the site consist of
clayey to sandy silt and silty clay to depths of approximately 65 feet BGS. There appears to be a ground
water trough oriented toward the northeast and centered around the UST basin. The horizontal hydraulic
gradient was convergent from the southeast and northwest with gradients of approximately 0.04 feet per
foot. There is a general ground water flow trend toward the north-northeast. The vertical hydraulic

gradient calculated for paired wells MW-4/TW-1 was approximate 0.05 feet per foot in the upward
direction.

Rising head slug tests were conducted on MW-8, MW-9, and TW-1. The average hydraulic conductivity
calculated for the Type II monitoring wells was 1.449 x 10-3 feet per minute (2.086 feet per day) and the
average seepage velocity was 4.17 x 10-1 feet per day (152 feet per year). The hydraulic conductivity
calculated for the Type III monitoring well was 1.015 x 10-2 feet per minute (14.62 feet per day). The
seepage velocity calculated for the Type III monitoring well was 2.34 feet per day (854 feet per year).

The site risk classification has been deemed as intermediate risk based on the presence of free product
and/or GCL exceedances. Therefore, free product must be removed from the site and the ground water
contamination must be remediated to concentrations less than the GCLs.

Free product removal should continue at the site until free product is no longer present. A ground water
sampling event should be conducted at the site in February 2022 to confirm the results of the CSA ground
water sampling events. Based on the results of the February 2022 sampling event, a decision to pursue
corrective action or allow for natural attenuation can be made.
