1.0 BACKGROUND INFORMATION
The subject site is the Speedway 7972 (former WilcoHess 353) located at 502
Wilkesboro Boulevard SE in Lenoir, North Carolina (Drawing 1.1). On October 1, 2014,
Speedway LLC acquired the site from Hess Corporation, who had previously acquired
the site from WilcoHess LLC. The site is currently in use as a convenience store and retail
petroleum dispensing facility. The facility operates three 12,000-gallon gasoline USTs,
one 12,000-gallon diesel UST, and one 10,000-gallon kerosene UST. The layout of the
facility is shown on Drawing 1.2.
Gasoline free product was historically present on the water table in monitoring wells
MW-1 and MW-8, but has not been detected at the site since September 2012. The
site is currently classified as intermediate risk due to the presence of a downgradient
surface water body (UT to Lower Creek) located within 500 feet of the source area of the
release. The UT to Lower Creek is located approximately 125 feet south and hydraulically
downgradient of the source area of the release, and petroleum-related constituents have
historically been detected in surface water samples collected from this drainage feature
at concentrations exceeding the NCSWQS. The approximate surface water sampling
locations are identified on Drawing 1.2. Selected historical site assessment data is
included in Appendix A.
This report documents the results of the groundwater monitoring and surface water
sampling activities conducted at the site in November 2020.The opinions included
herein are based on our experience and information obtained during the study. This
report is based on limited observations made on the dates noted using procedures
described herein. If additional information becomes available, we request the opportunity
to review the information, reassess the potential environmental concerns, and modify our
conclusions, if appropriate.
A Trust Fund Pre-Approval Task Authorization (TA #21) was obtained from NCDEQ
on September 17, 2020 and covered the sampling and laboratory analysis of six
groundwater monitoring wells and three surface water points. This report documents
these activities and the results.
2.0 SITE HISTORY AND SOURCE CHARACTERIZATION
2.1 UST Information
According to the UST Section’s Registration database, the site’s Facility I.D. number is
0-033119. The following table summarizes the UST System information.
Tank No.Const.Type Install Date Size (Gallons)Status Last Contents
Previous

5 Steel 11/1/1989 10,000 In Use Kerosene None
2.2 UST System Owner/Operator
The UST system is owned and operated by Speedway LLC.
2.3 Information on Source of Release
Based on impacted soil and the historical presence of free product near the gasoline
USTs, it appears that a release occurred from these tanks. Although the causes and
dates of the release(s) are unknown, it appears that the releases are not on-going, since
the UST system passed Precision’s tightness tests and the UST systems have been
upgraded to current standards.
2.4 Regional Geology and Hydrogeology
According to the map titled Geology of North Carolina (1985), prepared by the North
Carolina Geological Survey Section of the NCDENR, the subject site is located in the
intrusive rocks of the Inner Piedmont physiographic province. The site appears to be
located on top of metamorphic rocks described as “Migmatitic Granitic Gneiss - foliated
to massive, granitic to quartz dioritic; biotite gneiss and amphibolite common.”
Groundwater in the North Carolina Piedmont region is typically found within the pore
spaces of the saprolite and alluvium deposits and within the fractures of the underlying
bedrock. In general, larger quantities of groundwater are available in valleys and
low‑lying areas where saprolite thickness is usually greater.
2.5 Site Geology and Hydrogeology
Refer to the historical documents in Appendix A for a summary of the geological and
hydrogeological parameters encountered during performance of the site activities as well
as the soil boring logs and well constructions logs for the well system.
Measurements taken during historical site activities indicate the following conditions:
•Groundwater flow across the site is generally toward the south-southwest;
•The average horizontal hydraulic gradient across the site is estimated at 0.038
foot/foot;
Groundwater Monitoring Report

Lenoir, North Carolina
January 22, 2021
Page 2
•The horizontal seepage velocity for shallow groundwater at the site is estimated
at approximately 98 feet/year;
•The vertical hydraulic gradient is approximately 0.046 foot/foot downward; and
•The hydraulic conductivity was estimated to be 0.18 feet/day.
3.0 POTENTIAL RECEPTORS
Receptor information for the site was previously documented in Mid-Atlantic’s Phase I
Limited Site Assessment Report dated November 13, 2006.A receptor survey update
was not conducted during this monitoring event. Please refer to previous reports for
detailed receptor information. As indicated, the site is currently classified as
“intermediate” risk due to the presence of a surface water body (UT to Lower Creek)
located approximately 125 feet south and hydraulically downgradient of the release area
(Drawing 1.2).
According to Classifications and Water Quality Standards Assigned to the Waters of the
Yadkin-Pee Dee River Basin, Lower Creek is classified as a Class C Water. A Class C
Water is defined as freshwaters that must be protected for secondary recreation, fishing,
aquatic life including propagation and survival, and wildlife.
4.0 FIELD ACTIVITIES
4.1 Liquid Level Measurements
Mid-Atlantic personnel collected groundwater level measurements from selected site
monitoring wells MW-1, MW-3, MW-8, MW-11, MW-15, and MW-16 on November 18,
2020 using an electronic water level indicator. Monitoring well construction details are
provided in Table 4.1. Groundwater level measurements were collected using the
procedures outlined in Appendix B. The results of these activities, along with historical
measurements, are summarized in Table 4.2.
4.2 Monitoring Well Sample Collection
Mid-Atlantic personnel collected groundwater samples from six selected site monitoring
wells (MW-1, MW-3, MW-8, MW-11, MW-15, and MW-16) on November 18, 2020. The
sampling event was conducted to monitor plume concentrations in the vicinity of the
source area of the release (MW-1, MW-3 and MW-8) and immediately upgradient of
the receiving UT to lower Creek (MW-11, MW-15 and MW-16). Groundwater samples
were collected using the procedures outlined in Appendix B. Samples were shipped to
Pace Analytical in Mt. Juliet, Tennessee and analyzed by the methods shown on the
chain-of-custody record provided in Appendix C.

4.3 Surface Water Sample Collection
On November 18, 2020, Mid-Atlantic personnel collected three surface water samples
from the UT to Lower Creek, located to the south and downgradient of the source
area of the release. The approximate sample locations (Stream #1, Stream #2, and
Stream #3) are shown on Drawing 1.2.Surface water samples were collected using
the procedures outlined in Appendix B. Samples were shipped to Pace Analytical in Mt.
Juliet, Tennessee and analyzed by the methods shown on the chain-of-custody record in
Appendix C.
5.0 DISCUSSION OF SAMPLING RESULTS
5.1 Summary of Analytical Results
Groundwater
The laboratory analytical report and chain-of-custody record for groundwater samples
collected in November 2020 are provided in Appendix C and summarized in Table 5.1,
which also includes a summary of historical groundwater sampling data for selected
target compounds.As summarized, the groundwater sample collected from source area
monitoring well MW-1 exhibited an increase in toluene and naphthalene concentrations
to an excess of ten times the NCSWQS but below the GCLs. Source area monitoring
well MW-8 exhibited benzene, toluene and naphthalene concentrations in excess of
ten times the NCSWQS but below the GCLs. No other samples collected during the
monitoring event exceeded ten times the NCSWQS, including the wells located
immediately upgradient of the UT to Lower Creek (MW-11, MW-15 and MW-16).
Surface Water
The laboratory analytical report and chain-of-custody record for surface water samples
collected in November 2020 are provided in Appendix C and summarized in Table 5.2,
which also includes a summary of historical surface water sampling data for selected
target compounds. As summarized, target compounds were not detected in surface
water samples Stream #1, Stream #2, or Stream #3 at concentrations in excess of their
applicable NCSWQS or EPA NWQC for the November 2020 sampling event.
5.2 Description of Current Plume Size and Location
Free product has not been detected at the site since September 2012 and
dissolved-phase groundwater contaminants appear to have migrated hydraulically
downgradient of the source area of the release, in the direction of the UT to Lower
Creek.The dissolved-phase groundwater contaminant plume appears to be defined
by the current monitoring well network to the extent of ten times the NCSWQS as
Groundwater Monitoring Report
Speedway 7972 (Former WilcoHess 353)
Lenoir, North Carolina
January 22, 2021
Page 4
concentrations did not exceed ten times the NCSWQS for samples collected from
monitoring wells MW-11, MW-15 or MW-16, located immediately upgradient of the UT to
Lower Creek.
Benzene and toluene isoconcentration maps for the November 2020 sampling event
are provided as Drawings 5.1 and 5.2, respectively. When compared with the results
of previous sampling events, the groundwater contaminant concentrations appear to be
generally consistent with more recent sampling events, with the exception of MW-1,
which exhibited an increasing trend. Since the release was discovered, an overall
attenuation of contaminant concentrations appears evident.
Target compound concentrations for surface water samples collected from the UT to
Lower Creek have not been detected in excess of the NCSWQS since February 2013.
Based on the current available data, additional monitoring events appear to be warranted
to continue to evaluate contaminant trends associated with wells MW-1, MW-3, MW-8,
MW-11, MW-15 and MW-16 and the downgradient UT to Lower Creek.
5.3 Additional Monitoring Information
•Elevation Comparison of the Water Table to the UT to Lower Creek
The elevations of the shallow water table for three monitoring wells (MW-2, MW-11,
and MW-12) in the vicinity of the UT to Lower Creek were previously compared to
the elevations of two surveyed points in the drainage feature. These activities were
documented in Mid-Atlantic’s Groundwater Monitoring and Free Product Recovery
Report dated June 15, 2012 and the results of water elevation comparisons since that
time are summarized in Table 5.3. As indicated, it appears the bottom of the ditch is
lower in elevation than the water table, suggesting that groundwater is discharging into
the drainage feature.
•Proximity of Plume to Nearest Receptor
The nearest surface water body is the UT to Lower Creek, located approximately 125
feet to the south and hydraulically downgradient of the source area of release. Based on
relative elevations of the water table in this area to the bottom of the UT, groundwater
appears to be discharging to this drainage feature (Table 5.3). Monitoring wells MW-11,
MW-15 and MW-16 are located immediately upgradient of the UT to Lower Creek
and thus provide the best data for use in groundwater to surface water comparisons.
Therefore, based on the results of the current and historical sampling events, the
dissolved-phase groundwater contaminant plume appears to be migrating off-site and
discharging to the UT to Lower Creek.
•Groundwater Flow Direction
Groundwater Monitoring Report
Speedway 7972 (Former WilcoHess 353)
Lenoir, North Carolina
January 22, 2021
Page 5
Groundwater flow direction in the surficial aquifer was determined by development of a
water table contour map (Drawing 5.3) based upon water table elevation data obtained
from select site monitoring wells in November 2020. Interpretation of the water level data
for the current sampling event suggests that the groundwater flow direction is primarily
towards the southwest, with a hydraulic gradient (measured from MW-8 toward MW-15)
of approximately 0.073 ft/ft. The hydraulic gradient was calculated using the procedure
discussed in Appendix B.
6.0 FUTURE SITE REMEDIATION
The site is currently ranked intermediate risk due to the presence of surface water within
500 feet of the source area of release. The UT to Lower Creek is located approximately
125 feet south and hydraulically downgradient of the release, and petroleum-related
constituents have historically been detected in the surface water samples collected
from this drainage feature (note that these constituents have not been detected in
concentrations exceeding the NCSWQS since February 2013). As such, the proposed
remedial approach for the site at this time includes continued monitored natural
attenuation. Although contaminants are present in groundwater near the downgradient
receptor (UT to Lower Creek), the plume appears to be relatively stable and the
contaminants do not appear to be causing surface water standard exceedances in the
downgradient receptor.
If groundwater contaminant concentrations should significantly increase, supplemental
remedial measures may be required. In that case, the proposed remedial approach will
utilize chemical oxidation technologies to reduce contaminant concentrations within the
source area of the release (i.e. the immediate vicinity of wells MW-1 and MW-8) and
mitigate the discharge of petroleum-related constituents to the receiving surface waters.
Under this approach, monitoring wells MW-11, MW-15, and MW-16 will be used to
support the application of ISOC (or similar) and formation of an “oxygen barrier” between
the source area of the release and the UT to Lower Creek.
7.0 SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS
The November 2020 groundwater/surface water monitoring activities are summarized as
follows:
•Groundwater samples were collected from six selected site monitoring wells on
November 18, 2020 to monitor plume concentrations in the vicinity of the source
area of the release (MW-1, MW-3 and MW-8) and immediately upgradient of the
receiving UT to lower Creek (MW-11, MW-15 and MW-16); and
•Three surface water samples were collected from the downgradient UT to Lower
Creek, located approximately 125 feet south of the source area of the release.
Based on the results of the sampling event, Mid-Atlantic concludes the following:
Groundwater Monitoring Report
Speedway 7972 (Former WilcoHess 353)
Lenoir, North Carolina
January 22, 2021
Page 6
•Free product was not detected at the site during the November 2020 groundwater
monitoring event and has not been detected at the site since September 2012;
•The groundwater sample collected from source area monitoring well MW-1
exhibited toluene and naphthalene concentrations in excess of ten times the
NCSWQS but below the GCLs.MW-8 exhibited benzene, toluene, and
naphthalene concentrations in excess of ten times the NCSWQS but below the
GCLs. No other samples collected during the monitoring event exceeded ten
times the NCSWQS, including the wells located immediately upgradient of the UT
to Lower Creek (MW-11, MW-15 and MW-16);
•Surface water samples collected from the UT to Lower Creek did not exhibit
target compound concentrations in excess of the NCSWQS for the current
monitoring event. Additionally, target compounds for surface water samples
collected from the UT to Lower Creek have not been detected at concentrations
exceeding the NCSWQS since February 2013;
•When compared with the results of previous sampling events, the overall
groundwater contaminant concentrations appear to be generally consistent with
recent sampling events, with the exception of a general increase in
concentrations in MW-1. During this sampling event, an increase in benzene,
toluene, xylenes, and naphthalene concentrations was observed in the
groundwater sample collected from this well. However, since the release was
discovered, an overall attenuation of contaminant concentrations appears
evident;and
•The dissolved-phase groundwater contaminant plume is currently defined by the
existing monitoring well network to the extent of ten times the NCSWQS.
Based on these conclusions, Mid-Atlantic recommends the following:
•Continued groundwater/surface water monitoring to gain additional information
regarding the stability/decay of the contaminant plume and the potential for
impact to the downgradient surface water receptor. If the plume remains stable
and the NCSWQS are not exceeded, the site should continue to be monitored
until NCDEQ can confirm that the site is eligible for risk downgrade; however, if
groundwater concentrations increase significantly, the use of chemical oxidation
technologies should be considered; and
•Submittal of this report to the NCDEQ, Asheville Regional Office, UST Section

If the answer to question #3 is “YES”, please generally describe in this cell the possible
reason(s) and outline proposed remedies. (This should be described in more detail in the
report text above.)
Natural attenuation is not currently part of the remedial strategy at this site, although it may
be in the future. Remedial efforts to date have focused on removing free product from the
water table
4 Does any known or suspected source zone soil contamination or free
product remain outside of the assessed area that could be inhibiting
natural attenuation?
5 Has there been an unexpected increase in contaminant mass sufficient
to suggest a potential new release from a separate onsite or offsite
source?
If the answer to either question #4 or #5 is “YES”, generally describe in this cell any actions
recommended to further assess or clean up this known or suspected source.
Estimated mass calculations indicate fluctuations in volume of free product in the subsurface
over time. Ethanol and oxygenates analysis of the free product was performed in December
2018 and the sample did not contain these compounds (were not indicative of a new/ongoing
release). Therefore, fluctuations in volume may be related to natural fluctuation of the water
table, resulting in fluctuating free product thicknesses. These data are best evaluated as
trends over time. Free product thicknesses have remained relatively steady overall since the
beginning of 2019.

APPENDIX B MID-ATLANTIC FIELD PROCEDURES
Groundwater Sampling Procedures
I. Sample Collection
A. Monitoring Wells
Prior to sample collection, each well is purged of three to five standing well volumes
or to dryness to remove stagnant water from the well and well bore in an effort to
collect samples that are representative of the water quality in the formation
surrounding each well. Purging is performed either with a new, polyethylene bailer
dedicated to each well, or with a decontaminated pump. Samples are retrieved from
the monitoring well using the dedicated bailer. New nylon string is used on each
dedicated bailer, and new nitrile sampling gloves are donned prior to purging and
sampling of each well.
B. Geoprobe “Screen Point Sampler”
The screen point sampler is a “grab” sampling device that is driven into the
saturated zone and a surrounding metal sheath is retracted, exposing a screen.
Groundwater entering the screen is then drawn to land surface through disposable
tubing that is placed through the hollow push rods. The sample is collected from the
tubing into the appropriate sampling glassware.
C. Water-Supply Wells
Water samples are typically collected from the available spigot that is nearest to the
well. The water is allowed to run at a high flow from the spigot for approximately 10
to 15 minutes to allow the water in the delivery lines to be purged. The sample flow
is then reduced and the samples are collected directly into pre-labeled containers as
described below. New nitrile sampling gloves are donned prior to sampling of each
well.
D. Treatment System Influent/Effluent
Samples are typically collected from the influent or effluent of pump-and-treat
groundwater remediation systems using designated sampling ports in the influent
and effluent water transport lines. The water is typically allowed to run for several
seconds to clear potential debris in the sampling port. The sample is then collected
directly into sampling containers as described below. New nitrile sampling gloves
are donned prior to sample collection.
II. Preparation for Laboratory Analysis
Groundwater samples are decanted directly into laboratory-prepared, pre-labeled,
sampling containers, packed in ice, and shipped to a certified laboratory under chain-of-
custody control. Laboratory analyses performed on the samples are specified on the chain-
of-custody.
Surface Water Sampling Procedures
I. Sample Collection
Surface water samples are collected using properly decontaminated equipment or directly into
laboratory-supplied sampling containers. Samples are generally collected at or near a suspected
discharge point for contaminated groundwater. In small streams and ditches, samples are
collected as close to mid-channel as possible. Samples are not collected from stagnant areas or
areas of turbulent flow.
II. Preparation for Laboratory Analysis
Surface water samples are decanted directly into laboratory-prepared, pre-labeled, sampling
containers, packed in ice, and shipped to a certified laboratory under chain-of-custody control.
Laboratory analyses performed on the samples are specified on the chain-of-custody.
Hydraulic Gradient Determination Procedure
The hydraulic gradient, which is a measure of the “steepness” of the water table, is
determined by dividing the change in the elevation (in feet) of the water table over the
change in horizontal distance (in feet) between two measuring points. Typically, the
gradient is determined after the Water Table Elevation Contour Map is prepared. Two
wells are typically selected that, when a line is drawn between the wells, the orientation of
this line approximates the direction of groundwater flow. The greater the horizontal
distance between the lines, the more representative the hydraulic gradient value will be for
the site. If two wells are not arranged in line with groundwater flow, the hydraulic gradient
can be estimated by performing the same calculation using the contours generated for the
groundwater flow direction map. The units for the hydraulic gradient are feet/feet.
The hydraulic gradient (measured from MW-8 to MW-15) for the subject site was
determined as follows:
Gradient = dh/dl = (91.55 – 84.10) / 102 = 0.073 ft/ft
where:
dh = change in head (more specifically, water table elevation) in feet
dl = horizontal distance (in feet) between monitoring wells or other head measurement
points.

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

1.0 BACKGROUND INFORMATION
The subject site is the Speedway 7972 (former WilcoHess 353) located at 502
Wilkesboro Boulevard SE in Lenoir, North Carolina (Drawing 1.1). On October 1, 2014,
Speedway LLC acquired the site from Hess Corporation, who had previously acquired
the site from WilcoHess LLC. The site is currently in use as a convenience store and retail
petroleum dispensing facility. The facility operates three 12,000-gallon gasoline USTs,
one 12,000-gallon diesel UST, and one 10,000-gallon kerosene UST. The layout of the
facility is shown on Drawing 1.2.
Gasoline free product was historically present on the water table in monitoring wells
MW-1 and MW-8.Free product, which had not been detected at the site since September
2012, was present in MW-1 during Mid-Atlantic's June 8, 2021 and July 15, 2021 site
visits. The site is currently classified as intermediate risk due to the presence of a
downgradient surface water body (UT to Lower Creek) located within 500 feet of the
source area of the release. The UT to Lower Creek is located approximately 125
feet south and hydraulically downgradient of the source area of the release, and
petroleum-related constituents have historically been detected in surface water samples
collected from this drainage feature at concentrations exceeding the NCSWQS. The
approximate surface water sampling locations are identified on Drawing 1.2. Selected
historical site assessment data is included in Appendix A.
This report documents the results of the groundwater monitoring and surface water
sampling activities conducted at the site on June 8, 2021, aggressive fluid-vapor recovery
(AFVR) remedial activities conducted at the site on June 14, 2021, and additional
groundwater monitoring and surface water sampling conducted at the site on July
15,2021.The opinions included herein are based on our experience and information
obtained during the study. This report is based on limited observations made on the dates
noted using procedures described herein. If additional information becomes available, we
request the opportunity to review the information, reassess the potential environmental
concerns, and modify our conclusions, if appropriate.
A Trust Fund Pre-Approval Task Authorization (TA #22) was obtained from NCDEQ
on April 14,2021 and covered the sampling and laboratory analysis of six groundwater
monitoring wells and three surface water points. Following discovery of free product
during sampling events on June 8, 2021, a Trust Fund Pre-Approval Task Authorization
(TA #23) was obtained on June 10, 2021 which covered an AFVR event and the
sampling of one groundwater monitoring well and surface water points.This report
documents the activities and results for the groundwater sampling for both TAs. A
separate Free Product Recovery Report will be generated to document the AFVR results.
2.0 SITE HISTORY AND SOURCE CHARACTERIZATION
2.1 UST Information
According to the UST Section’s Registration database, the site’s Facility I.D. number is
0-033119. The following table summarizes the UST System information.

2.2 UST System Owner/Operator
The UST system is owned and operated by Speedway LLC.
2.3 Information on Source of Release
It appears that a release originally occurred from the gasoline tanks based on impacted
soil and the historical presence of free product near the gasoline USTs. The causes
and dates of the original release(s) are unknown. Mid-Atlantic visited the site on June
8, 2021 to perform semi-annual groundwater and surface water sampling at the site
and discovered approximately four feet of free product in MW-1. Testing of the UST
system was subsequently conducted by Crompco, LLC on June 10, 2021 and the regular
unleaded gasoline line as well as the premium unleaded gasoline spill bucket did not
pass the tests. The line failure occurred across the manifold in the former midgrade
unleaded piping run.Tideland Construction capped the line at the dispenser and former
midgrade unleaded STP.Crompco re-tested the regular unleaded line after repairs
and obtained passing results on June 14, 2021.Although the spill bucket failed the
hydrostatic testing, it is not believed to be a significant contributor to the free product
found in well MW-1.

2.4 Regional Geology and Hydrogeology
According to the map titled Geology of North Carolina (1985), prepared by the North
Carolina Geological Survey Section of the NCDENR, the subject site is located in the
intrusive rocks of the Inner Piedmont physiographic province. The site appears to be
located on top of metamorphic rocks described as “Migmatitic Granitic Gneiss - foliated
to massive, granitic to quartz dioritic; biotite gneiss and amphibolite common.”
Groundwater in the North Carolina Piedmont region is typically found within the pore
spaces of the saprolite and alluvium deposits and within the fractures of the underlying
bedrock. In general, larger quantities of groundwater are available in valleys and
low‑lying areas where saprolite thickness is usually greater.
2.5 Site Geology and Hydrogeology
Refer to the historical documents in Appendix A for a summary of the geological and
hydrogeological parameters encountered during performance of the site activities as well
as the soil boring logs and well constructions logs for the well system.
Measurements taken during historical site activities indicate the following conditions:
•Groundwater flow across the site is generally toward the south-southwest;
•The average horizontal hydraulic gradient across the site is estimated at 0.038
foot/foot;
•The horizontal seepage velocity for shallow groundwater at the site is estimated
at approximately 98 feet/year;
•The vertical hydraulic gradient is approximately 0.046 foot/foot downward; and
•The hydraulic conductivity was estimated to be 0.18 feet/day.
3.0 POTENTIAL RECEPTORS
Receptor information for the site was previously documented in Mid-Atlantic’s Phase I
Limited Site Assessment Report dated November 13, 2006.A receptor survey update
was not conducted during this monitoring event. Please refer to previous reports for
detailed receptor information. As indicated, the site is currently classified as
“intermediate” risk due to the presence of a surface water body (UT to Lower Creek)
located approximately 125 feet south and hydraulically downgradient of the release area
(Drawing 1.2).
According to Classifications and Water Quality Standards Assigned to the Waters of the
Yadkin-Pee Dee River Basin, Lower Creek is classified as a Class C Water. A Class C
Water is defined as freshwaters that must be protected for secondary recreation, fishing,
aquatic life including propagation and survival, and wildlife.

4.0 FIELD ACTIVITIES
4.1 Liquid Level Measurements
Mid-Atlantic personnel collected groundwater level measurements from selected site
monitoring wells MW-3, MW-8, MW-11, MW-15, and MW-16 on June 8, 2021 using
an electronic water level indicator. During well gauging free product was discovered in
MW-1. A bailer was used to confirm presence of free product which was found to have
a thickness of approximately four feet. Mid-Atlantic personnel did not have an oil/water
interface probe on site to gauge this well during this sampling event. Utilizing an oil/water
interface probe during subsequent sampling on July 15, 2021 free product thickness
was measured to be 3.38 feet.Monitoring well construction details are provided in Table
4.1. Groundwater level measurements were collected using the procedures outlined in
Appendix B. The results of these activities, along with historical measurements, are
summarized in Table 4.2.
4.2 Monitoring Well Sample Collection
Mid-Atlantic personnel collected groundwater samples from five of six selected site
monitoring wells (MW-3, MW-8, MW-11, MW-15, and MW-16) on June 8, 2021. Free
product was discovered in MW-1 and thus was not sampled. The sampling event was
conducted to monitor plume concentrations in the vicinity of the source area of the
release (MW-1, MW-3 and MW-8) and immediately upgradient of the receiving UT to
lower Creek (MW-11, MW-15 and MW-16). Groundwater samples were collected using
the procedures outlined in Appendix B. Samples were shipped to Pace Analytical in Mt.
Juliet, Tennessee and analyzed by the methods shown on the chain-of-custody record
provided in Appendix C.
4.3 Surface Water Sample Collection
On June 8, 2021 and July 15, 2021,Mid-Atlantic personnel collected three surface water
samples (six surface water samples total)from the UT to Lower Creek, located to the
south and downgradient of the source area of the release. The approximate sample
locations (Stream #1, Stream #2, and Stream #3) are shown on Drawing 1.2.Surface
water samples were collected using the procedures outlined in Appendix B. Samples
were shipped to Pace Analytical in Mt. Juliet, Tennessee and analyzed by the methods
shown on the chain-of-custody record in Appendix C.

The laboratory analytical report and chain-of-custody record for groundwater samples
collected on June 8, 2021 are provided in Appendix C and summarized in Table 5.1,
which also includes a summary of historical groundwater sampling data for selected
target compounds.Free product was detected in MW-1 during initial measurement
activities and thus was not sampled. The groundwater sample collected from monitoring
well MW-3 exhibited detectable benzene concentrations above the NCGQS.MW-8
exhibited benzene, toluene, and naphthalene concentrations in excess of ten times the
NCSWQS but below the GCLs. No other samples collected during the monitoring event
exceeded ten times the NCSWQS, including the wells located immediately upgradient of
the UT to Lower Creek (MW-11, MW-15 and MW-16)
Surface Water
The laboratory analytical reports and chain-of-custody records for surface water samples
collected on June 8, 2021 and July 15, 2021 are provided in Appendix C and summarized
in Table 5.2, which also includes a summary of historical surface water sampling data
for selected target compounds. As summarized, target compounds were not detected in
surface water samples Stream #1, Stream #2, or Stream #3 at concentrations in excess
of their applicable NCSWQS or EPA NWQC for either the June 8, 2021 or July 15,
2021 sampling event.
5.2 Description of Current Plume Size and Location
Until this recent groundwater sampling event, free product had not been detected at the
site since August of 2012 (in well MW-8) and dissolved-phase groundwater contaminants
appear to have been migrating hydraulically downgradient of the source area of the
release, in the direction of the UT to Lower Creek.The dissolved-phase groundwater
contaminant plume appears to be defined by the current monitoring well network to
the extent of ten times the NCSWQS as concentrations did not exceed ten times
the NCSWQS for samples collected from monitoring wells MW-11, MW-15 or MW-16,
located immediately upgradient of the UT to Lower Creek.
Benzene and toluene isoconcentration maps for the June 8, 2021 sampling event are
provided as Drawings 5.1 and 5.2, respectively. When compared with the results of
previous sampling events, the groundwater contaminant concentrations appear to be
generally consistent with more recent sampling events, with the exception of free product
in MW-1 and an increasing trend in MW-8, MW-15, and MW-16. The increase
of groundwater contaminant concentrations appear to coincide with a recent release
from the abandoned product line. Although the spill bucket failed the hydrostatic test, it is
not believed to be a significant contributor to the free product found in well MW-1.

For surface water samples collected from the UT to Lower Creek, target compounds
have not been detected in excess of the NCSWQS since September 2014. Based on the
current available data, additional monitoring events appear to be warranted to continue
to evaluate contaminant trends in the groundwater and the downgradient UT to Lower
Creek.
5.3 Additional Monitoring Information
•Elevation Comparison of the Water Table to the UT to Lower Creek
The elevations of the shallow water table for three monitoring wells (MW-2, MW-11,
and MW-12) in the vicinity of the UT to Lower Creek were previously compared to
the elevations of two surveyed points in the drainage feature. These activities were
documented in Mid-Atlantic’s Groundwater Monitoring and Free Product Recovery
Report dated June 15, 2012 and the results of water elevation comparisons since that
time are summarized in Table 5.3. As indicated, it appears the bottom of the ditch is
lower in elevation than the water table, suggesting that groundwater is discharging into
the drainage feature.
•Proximity of Plume to Nearest Receptor
The nearest surface water body is the UT to Lower Creek, located approximately 125
feet to the south and hydraulically downgradient of the source area of release. Based on
relative elevations of the water table in this area to the bottom of the UT, groundwater
appears to be discharging to this drainage feature (Table 5.3). Monitoring wells MW-11,
MW-15 and MW-16 are located immediately upgradient of the UT to Lower Creek
and thus provide the best data for use in groundwater to surface water comparisons.
Therefore, based on the results of the current and historical sampling events, the
dissolved-phase groundwater contaminant plume appears to be migrating off-site and
discharging to the UT to Lower Creek.
•Groundwater Flow Direction
Groundwater flow direction in the surficial aquifer was determined by development of a
water table contour map (Drawing 5.3) based upon water table elevation data obtained
from select site monitoring wells on June 8, 2021. Interpretation of the water level data
for the current sampling event suggests that the groundwater flow direction is primarily
towards the southwest, with a hydraulic gradient (measured from MW-8 toward MW-15)
of approximately 0.069 ft/ft. The hydraulic gradient was calculated using the procedure
discussed in Appendix B.

6.0 FUTURE SITE REMEDIATION
The site is currently ranked intermediate risk due to the presence of surface water within
500 feet of the source area of release. The UT to Lower Creek is located approximately
125 feet south and hydraulically downgradient of the release, and petroleum-related
constituents have historically been detected in the surface water samples collected
from this drainage feature (note that these constituents have not been detected in
concentrations exceeding the NCSWQS since September 2014). Free product was
discovered in MW-1 on June 8, 2021 during this sampling event.An AFVR event was
conducted on June 14, 2021 and is described in a separate report. The proposed
remedial approach for the site at this time includes future AFRV events on MW-1.
Although contaminants are present in groundwater near the downgradient receptor (UT
to Lower Creek), the plume appears to be relatively stable and the contaminants do not
appear to be causing surface water standard exceedances in the downgradient receptor.
7.0 SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS
The June 8, 2021 and July 15, 2021 groundwater/surface water monitoring activities are
summarized as follows:
•Groundwater samples were collected from five of six selected site monitoring
wells on June 8, 2021 to monitor plume concentrations in the vicinity of the source
area of the release (MW-3 and MW-8; free product in MW-1) and immediately
upgradient of the receiving UT to Lower Creek (MW-11, MW-15 and MW-16);
•Free product was discovered during both attempts to collect groundwater sample
from MW-1 on June 8, 2021 and July 15, 2021 and thus was not sampled. The
free product is believed to have been released from a portion of abandoned
product line, which has since been repaired; and
•A total of six surface water samples (three on June 8, 2021 and three on July
15, 2021)were collected from the downgradient UT to Lower Creek, located
approximately 125 feet south of the source area of the release.
Based on the results of the sampling event, Mid-Atlantic concludes the following:
•Free product was detected in MW-1 at the site during the June 8, 2021
groundwater monitoring event;
•After the discovery of free product in well MW-1, an AFVR was conducted on the
well (results will be reported in a separate report);
•MW-8 exhibited benzene, toluene, and naphthalene concentrations in excess
of ten times the NCSWQS but below the GCLs. No other samples collected
during the monitoring event exceeded ten times the NCSWQS, including the
wells located immediately upgradient of the UT to Lower Creek (MW-11, MW-15
and MW-16);

•Surface water samples collected from the UT to Lower Creek did not exhibit
target compound concentrations in excess of the NCSWQS for the current
monitoring event. Additionally, target compounds for surface water samples
collected from the UT to Lower Creek have not been detected at concentrations
exceeding the NCSWQS since September 2014;
•When compared with the results of previous sampling events, the overall
groundwater contaminant concentrations appear to be generally consistent with
more recent sampling events, with the exception of free product in MW-1 and
an increasing trend in MW-8, MW-15, and MW-16. The increase of groundwater
contaminant concentrations appear to coincide with a recent release from the
abandoned product line. Although the spill bucket failed the hydrostatic test, it is
not believed to be a significant contributor to the free product found in well MW-1;
•The new release from the line appears to be commingled with the existing
Incident No. 28414;
•The dissolved-phase groundwater contaminant plume is currently defined by the
existing monitoring well network to the extent of ten times the NCSWQS.
Based on these conclusions, Mid-Atlantic recommends the following:
•Continued free product recovery using AFVR;
•Continued groundwater water sampling with the inclusion of wells MW-6 and
MW-7 to gain additional information regarding the northern extent/source of
the plume following the recent release. Also, inclusion of wells MW-2 and MW-12
to gain additional information regarding the southern extent of the plume to
downgradient adjacent properties;
•Continued surface water sampling to monitor the potential for impact to the
downgradient surface water receptor;and
•Submittal of this report to the NCDEQ, Asheville Regional Office, UST Section

NO.DESCRIPTION YES NO
3 If applicable, will any of the proposed attenuation milestones under the
schedule approved in the Corrective Action Plan not be met? (within a
reasonable margin of error)
Not applicable (N/A).No Corrective Action Plan is in place.
If the answer to question #3 is “NO”, skip to the certification under #6 below.
If the answer to question #3 is “YES”, please generally describe in this cell the possible
reason(s) and outline proposed remedies. (This should be described in more detail in the
report text above.)
Natural attenuation is not currently part of the remedial strategy at this site, although it may
be in the future. Remedial efforts to date have focused on removing free product from the
water table.
4 Does any known or suspected source zone soil contamination or free
product remain outside of the assessed area that could be inhibiting
natural attenuation?
5 Has there been an unexpected increase in contaminant mass sufficient
to suggest a potential new release from a separate onsite or offsite
source?
If the answer to either question #4 or #5 is “YES”, generally describe in this cell any actions
recommended to further assess or clean up this known or suspected source.
Four feet of free product found during routine groundwater sampling on June 8, 2021 and
appears to have originated from an abandoned product line. Recommend additional AVFR
remedial events until the free product is eliminated.

APPENDIX B MID-ATLANTIC FIELD PROCEDURES
Groundwater Sampling Procedures
I. Sample Collection
A. Monitoring Wells
Prior to sample collection, each well is purged of three to five standing well volumes
or to dryness to remove stagnant water from the well and well bore in an effort to
collect samples that are representative of the water quality in the formation
surrounding each well. Purging is performed either with a new, polyethylene bailer
dedicated to each well, or with a decontaminated pump. Samples are retrieved from
the monitoring well using the dedicated bailer. New nylon string is used on each
dedicated bailer, and new nitrile sampling gloves are donned prior to purging and
sampling of each well.
B. Geoprobe “Screen Point Sampler”
The screen point sampler is a “grab” sampling device that is driven into the
saturated zone and a surrounding metal sheath is retracted, exposing a screen.
Groundwater entering the screen is then drawn to land surface through disposable
tubing that is placed through the hollow push rods. The sample is collected from the
tubing into the appropriate sampling glassware.
C. Water-Supply Wells
Water samples are typically collected from the available spigot that is nearest to the
well. The water is allowed to run at a high flow from the spigot for approximately 10
to 15 minutes to allow the water in the delivery lines to be purged. The sample flow
is then reduced and the samples are collected directly into pre-labeled containers as
described below. New nitrile sampling gloves are donned prior to sampling of each
well.
D. Treatment System Influent/Effluent
Samples are typically collected from the influent or effluent of pump-and-treat
groundwater remediation systems using designated sampling ports in the influent
and effluent water transport lines. The water is typically allowed to run for several
seconds to clear potential debris in the sampling port. The sample is then collected
directly into sampling containers as described below. New nitrile sampling gloves
are donned prior to sample collection.
II. Preparation for Laboratory Analysis
Groundwater samples are decanted directly into laboratory-prepared, pre-labeled,
sampling containers, packed in ice, and shipped to a certified laboratory under chain-of-
custody control. Laboratory analyses performed on the samples are specified on the chain-
of-custody.
Surface Water Sampling Procedures
I. Sample Collection
Surface water samples are collected using properly decontaminated equipment or directly into
laboratory-supplied sampling containers. Samples are generally collected at or near a suspected
discharge point for contaminated groundwater. In small streams and ditches, samples are
collected as close to mid-channel as possible. Samples are not collected from stagnant areas or
areas of turbulent flow.
II. Preparation for Laboratory Analysis
Surface water samples are decanted directly into laboratory-prepared, pre-labeled, sampling
containers, packed in ice, and shipped to a certified laboratory under chain-of-custody control.
Laboratory analyses performed on the samples are specified on the chain-of-custody.
Hydraulic Gradient Determination Procedure
The hydraulic gradient, which is a measure of the “steepness” of the water table, is
determined by dividing the change in the elevation (in feet) of the water table over the
change in horizontal distance (in feet) between two measuring points. Typically, the
gradient is determined after the Water Table Elevation Contour Map is prepared. Two
wells are typically selected that, when a line is drawn between the wells, the orientation of
this line approximates the direction of groundwater flow. The greater the horizontal
distance between the lines, the more representative the hydraulic gradient value will be for
the site. If two wells are not arranged in line with groundwater flow, the hydraulic gradient
can be estimated by performing the same calculation using the contours generated for the
groundwater flow direction map. The units for the hydraulic gradient are feet/feet.
The hydraulic gradient (measured from MW-8 to MW-15) for the subject site was
determined as follows:
Gradient = dh/dl = (90.65 – 83.66) / 102 = 0.069 ft/ft
where:
dh = change in head (more specifically, water table elevation) in feet
dl = horizontal distance (in feet) between monitoring wells or other head measurement
points.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.
J4 The associated batch QC was outside the established quality control range for accuracy.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.
J4 The associated batch QC was outside the established quality control range for accuracy.

Is it possible to change sample names on this after they have been submitted? I had a new guy do the sampling on
Thursday and he was not aware they had to be exactly the same name in order to enter into IDS. Or do I just have to
make new sample entry names in IDS?
