1.0 SITE HISTORY

The site is located at 1103 Huffman Mill Road in Burlington, North Carolina (Drawings 1 and 2). The
site is currently developed with an active gasoline station. Pilot was requested to provide Limited
Site Assessment (LSA) services related to the Notice of Regulatory Requirements (NORR) issued
by the North Carolina Department of Environmental Quality (NCDEQ) dated June 17, 2020. A
release was previously identified by others in the vicinity of the northeastern dispenser.

Pilot previously completed a LSA dated July 21, 2020. Based on the findings of the LSA, the
NCDEQ issued a NORR dated October 19, 2020 requiring that an Additional Risk Assessment
Report (ARA) be completed.

Pilot previously completed an Additional Risk Assessment Report (ARA) dated February 17, 2021.
Based on the findings of the ARA, the NCDEQ issued a NORR dated March 26, 2021 requiring that
a CSA be completed. The ARA assessment indicated that the extent of the impacted groundwater
was not reasonably defined. The concentrations of benzene detected in monitoring wells MW-3
and MW-4 exceeded its GCL.

Pilot completed a CSA dated June 7, 2021. Based on the findings of the CSA, the NCDEQ issued a
NORR dated August 19, 2022 requiring semi-annual groundwater monitoring events to
determine if monitored natural attenuation is feasible.

Project information is based on correspondence between NCDEQ personnel, McLeod Oil Company,
Inc. and Pilot and the previously completed activities.

1.1 UST Information

A suspected release was identified during a previous assessment by others. Laboratory analysis
of a soil sample (S-1) collected on September 18, 2017 detected gasoline range TPH above the
NC Action Level in the vicinity of the northeastern dispenser. UST information is summarized in
Table 1.

2.0 SITE GEOLOGY AND HYDROGEOLOGY

The United States Geological Survey (USGS) Topographic Map, Gibsonville and Burlington, North
Carolina Quadrangles depict a structure on the site. Elevations on the site range from
approximately 652 feet above mean sea level on the northeastern portion of the site to
approximately 659 feet above mean sea level on the southwestern portion of the site. Gum
Creek is depicted approximately 1,890 feet east of the site. Based on the review of the USGS
topographic map and observations of the general area and site topography, surface run-off
would be expected to flow generally to the southeast across the site.

The subject site is located within the Piedmont Physiographic Province. The Piedmont
Physiographic Province generally consists of hills and ridges which are dissected by a system of
swales and streams. The Piedmont Physiographic Province is predominantly underlain by
metamorphic rock (formed by heat, pressure and/or chemical action) and igneous rock (formed
directly from molten material). The topography and relief of the Piedmont Province has
developed from differential weathering of the igneous and metamorphic rock. Ridges and hills
have been developed in areas of less weathered rock. Because of the continued chemical and
physical weathering, rock in the Piedmont Physiographic Province is generally covered with a
mantle of soil that has weathered in place from the parent bedrock. These soils vary in thickness
and are referred to as residuum or residual soils. The residuum is typically finer grained and has
higher clay content near the surface because of the advanced weathering. Similarly, the soils
typically become coarser grained with increasing depth because of decreased weathering. As the
weathering decreases, the residual soils generally retain the overall appearance, texture and
foliations of the parent rock.

In general, groundwater movement in the Piedmont Physiographic Province is from higher to
lower elevations. As such, the presumed direction of groundwater flow is generally to the
southeast across the site. Based on the presumed groundwater flow direction, areas
immediately west are potentially up-gradient of the site.

Soils at the site consist of sandy clay from the ground surface to approximately 15 feet bgs and
silty clay from approximately 15 feet bgs to 75 feet bgs.

3.0 FIELD ACTIVITIES

The field activities were completed by Pilot on September 9, 2022. The field activities consisted
of collecting groundwater samples from existing monitoring wells MW-1, MW-2, MW-4, MW-6,
MW-7, MW-8, MW-9 and DW-1 (Drawing 3). Monitoring wells MW-3 and MW-5 were not
sampled based on approximately 2.53 feet and 1.91 feet, respectively, of free product being
measured in the wells.

3.1 Monitoring Well Sampling

Groundwater samples were collected from the existing monitoring wells that did not contain free
product, using a disposable bailer and new length of nylon string or peristaltic pump and new
length of polyethylene tubing. Prior to sampling, approximately three well volumes were purged
from the monitoring wells. The monitoring wells were purged to remove silt and sediment from
the groundwater and collect a representative sample of groundwater. After the purging was
completed, groundwater samples were collected in the sample containers provided by the
laboratory. Pilot personnel wore a new pair of disposable nitrile gloves during purging and
sampling. Each container was labeled and placed in a cooler containing ice to maintain the
samples at approximately 4 Celsius. The samples were then transported to Pace Analytical
(Pace) for chemical analysis. The groundwater samples collected were analyzed for volatile

organic compounds (VOCs) using Standard Method 6200B plus Oxygenates. A chain of custody
was maintained and is included in Appendix C. Isoconcentration maps for the compounds that
exceed their respective 2L Standard are included as Drawings 8 through 19, respectively. Copies
of the Monitoring Well Sampling Sheets are included in Appendix B.

The depth to the groundwater surface in monitoring wells MW-1 through MW-9 and DW-1 was
measured using a decontaminated water level indicator. The top of casing elevation for each
well was previously surveyed relative to an arbitrary benchmark (MW-1) with an assumed
elevation of 100.00 feet above mean sea level. The monitoring well elevations were utilized to
prepare a potentiometric surface map (Drawing 4). The relative groundwater elevations
collected from each monitoring well on September 9, 2022 are provided in Table 3. Based on
data collected during the assessment activities, the groundwater flow direction appears to be
generally toward the east-southeast beneath the site.

3.2 Water Supply Wells

Visual evidence of water supply wells; such as well houses, were observed within 1,500 feet of
the source area during the site reconnaissance. Water supply well questionnaires were sent to
13 property owners within 500 feet of the site. Three questionnaires were returned. Pilot
contacted the City of Burlington water department to determine if it supplied water to
surrounding properties that were identified to have water supply wells on the Alamance County
GIS website. Four properties that reportedly contain water supply wells are not provided
municipal water within 1,500 feet of the source area of the release. One of the water supply
wells is located within 1,000 feet of the source area of the release. Receptor information is
included on Table 4 and Drawing 5.

3.3 Groundwater Modeling

Groundwater modeling was not completed based on a surface water featuring not being
identified within 500 feet of the source area of the release.

3.4 Free Product Investigation and Recovery

Free product was observed in monitoring wells MW-3 and MW-5 during this sampling event, and
was not detected in previous sampling events. Approximately 2.53 feet of free product was
measured in MW-3 and 1.91 feet of free product was measured in MW-5.

3.5 Land Use

Currently the site is developed with a convenience store. The property is zoned as General Business.
A copy of the Alamance County zoning map is included as Drawing 6.

3.6 Property Owners and Occupants

The names and addresses of the property owners of the site and adjacent properties are included
in Table 2. A portion of an Alamance County GIS map with surrounding property locations is
presented as Drawing 7.

4.0 LABORATORY ANALYTICAL RESULTS

4.1 Groundwater Sample Analysis

Laboratory analysis of the groundwater samples collected from monitoring well MW-9 did not
detect targeted compounds above the laboratory detection limits. Laboratory analysis of the
groundwater samples collected from monitoring wells MW-1, MW-2, MW-4, MW-6, MW-7, MW-
8 and DW-1 detected several targeted compounds above their respective 2L Standards. The
concentration of benzene exceeds its GCL in the groundwater sample collected from monitoring
well MW-4. A summary of the groundwater analytical results is presented in Table 5. The
laboratory data sheets are included in the Appendix C. Groundwater Elevation versus
Concentration versus Time Graphs for monitoring wells MW-1, MW-4 and DW-1 are included in
Appendix A.

Pilot completed a mass contaminant calculation for the site (see table below), utilizing the
groundwater data. Please note that monitoring wells MW-3 and MW-5 contained free product;
therefore, an arbitrary estimated concentration of 30,000 ppb for benzene was utilized. The
groundwater contaminant mass is calculated by multiplying the mean groundwater
concentration by the source area calculation (surface area) by the depth of the groundwater
contamination zone by the porosity. The benzene concentrations were utilized for the
groundwater mass contaminant concentration. Based on the calculation, the total groundwater
contaminant mass is 360.98 Kg, a 124.21% increase in contaminant mass since November 29,
2021.

5.0 CONCLUSIONS

Based on the activities, Pilot concludes the following:

 Monitoring wells MW-3 and MW-5 were not sampled since 2.53 feet and 1.91 feet of free-
product was measured in the wells. It is Pilot’s understanding that the UST system has passed
Groundwater Monitoring Report

annual inspections and testing and it is Pilot’s understanding that there have been no
indications of a new release. The free product may be a result of the initial release that was
repaired. Based on the location of the monitoring wells, soil type and depth to groundwater
it may have taken some time for the product to migrate through the subsurface and be
detected in the downgradient wells from the dispenser release.

 Laboratory analysis of the groundwater samples collected from monitoring well MW-9 did not
detect targeted compounds above the laboratory detection limits. Laboratory analysis of the
groundwater samples collected from monitoring wells MW-1, MW-2, MW-4, MW-6, MW-7,
MW-8 and DW-1 detected several targeted compounds above their respective 2L Standards.
The concentration of benzene exceeds its GCL in the groundwater sample collected from
monitoring well MW-4. The overall concentrations in groundwater samples MW-1 and DW-1
are exhibiting a decreasing trend.

 The groundwater flow was calculated to be to be generally to the east-southeast.

 One of the water supply wells is located within 1,000 feet of the source area of the release
and upgradient from the site. Based on the Intermediate Risk classification for the incident,
the concentrations in the groundwater will need to decrease to below the GCLs to qualify for
incident closure.

 Based on the findings and intermediate ranking of the site, Pilot recommends free product
removal through an Aggressive Fluid and Vapor Removal (AFVR) event with continued
monitored natural attenuation and for this report to be submitted by the property
owner/responsible party to the NCDEQ, UST Section for their review.

6.0 RECOMMENDATIONS

Pilot recommends that the current property owner/responsible party submit a copy of this
Groundwater Monitoring Report to the NCDEQ, UST Section for their review. A Notice of Residual
Petroleum (NORP) is required to be recorded prior to a property transaction occurring.

7.0 QUALIFICATIONS OF REPORT

The activities and evaluative approaches used in this assessment are consistent with those
normally employed in assessment projects of this type. Our evaluation of site conditions has
been based on our understanding of the site project information and the data obtained during
our field activities.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
ANALYTE QUALIFIERS
The EPA or method required sample preservation degrades this compound, therefore acceptable recoveries may not be
achieved in sample matrix spikes.P5
