EXECUTIVE SUMMARY
On behalf of Pilot Flying J (Pilot), Apex Companies, LLC (Apex) has completed
groundwater monitoring activities associated with the soil and groundwater remediation system
located at the Pilot Travel Center #56, a retail gasoline station. In accordance with North
Carolina Department of Environmental Quality (NCDEQ) regulatory reporting requirements,
Apex has prepared a Corrective Action Monitoring Report for the subject property located at
2825 Lane Street in Kannapolis, North Carolina. This report includes results of the semi-annual
groundwater sampling for the period beginning January 1, 2021 and ending June 30, 2021. Per
NCDEQ directives dated March 5, 2021, two additional soil borings were advanced between the
site and potable residential supply wells and converted to monitoring wells during this phase to
further assist in delineation of the gasoline plume.
The site has been a working supplier of gasoline, diesel, and kerosene since at least 1984
and probably much earlier. From 1966 to 1972 the site was owned by the Humble Oil Company.
In 1972 the property owner became Exxon Corporation via a name change. Aerial photographs
obtained from Cabarrus County GIS department suggest that the site was a gas station by 1975.
It operated as a Starvin Marvin from 1984 and then Speedway America until October 26, 2001,
when Pilot Travel Centers, LLC purchased the property.
The objective of the Corrective Action Plan (CAP) prepared by Apex, was to maintain
groundwater quality conditions at the site below the applicable 2L Standards for benzene and
methyl tertbutyl ether (MTBE) while aggressively remediating source area groundwater and
minor soil contamination. The corrective action approach to achieve the aforementioned goals
for groundwater at the site consisted of an engineered air sparging and soil vapor extraction
(SVE) system coupled with monitored natural attenuation. Air sparging is effective in removing
volatile hydrocarbon constituents, including MTBE from groundwater. SVE captures volatile
organic vapors from the subsurface and provides an increased pressure gradient to enhance the
efficacy of the air sparging. The end of active remediation will be determined when asymptotic
conditions are reached in dissolved hydrocarbon concentrations in groundwater or when the
applicable 2L standards have been achieved, or risk can be reduced.
CAP implementation at the site began in April 2012. Prior to CAP implementation seven
monitoring wells (MW-11, MW-12, MW-19, MW-21, MW-23, MW-24, and DMW-3) were
above the benzene 2L limit of 1.0 micrograms per liter (µg/L). The MTBE 2L limit of 20 µg/L
was exceeded in eight monitoring wells (MW-11, MW-14, MW-17, MW-19, MW-21, MW-23,
MW-24, and DMW-3) prior to CAP implementation.
At the conclusion of 2nd Quarter 2021 CAP implementation there was no measurable
free -phase petroleum product at the site and the benzene 2L CAP endpoint was not exceeded in
any monitoring wells sampled. Monitoring wells MW-14 exceeded the MTBE 2L CAP
endpoint. Average analytical results decreased across the site as compared with previous
sampling events. Petroleum compounds have never been detected in any of the area potable
water supplies and sentinel wells such as MW-21, MW-22, and MW-25 continue to indicate that
the gasoline plume is confined to the original source zone identified and described in both the
Comprehensive Site Assessment (CSA) and approved CAP. Additional sentinel wells MW-27

Incident#36096

and MW-28 were installed during this phase and groundwater analytical results were consistent
with other sentinel wells, further documenting the gasoline plume confinement to the original
source zone.
Mass balance calculations indicate that the mass of MTBE and benzene remaining in the
aquifer are approximately 23 grams in groundwater, down from approximately 32 grams at the
conclusion of 2nd Quarter 2020 monitoring. Apex recommends initiating post -CAP monitoring
of the site for the following reasons:
• Mass balance calculations of remaining benzene and MTBE at the site show
approximately 23 grams of combined MTBE and benzene remain onsite as a
result of the incident. Additionally, a mass reduction for MTBE and benzene of
99.95% has been accomplished with the remediation system.
• Absence of measurable dissolved -phase petroleum compounds in area water
supply wells since source identification in June 2006.
• Absence of measurable dissolved -phase petroleum concentrations in sentinel
wells, MW-21, MW-22, MW-25, MW-27, and MW-28.
• Direction of shallow groundwater flow to the North -Northwest, which is cross -
gradient from potable water supplies.
• Presence of municipally supplied potable water to many of the area businesses
and residences.
Apex recommends continued system deactivation and an additional groundwater
monitoring event in November/December 2021 to continue observing dissolved -phase trends in
groundwater after system activation. Based on November/December 2021 dissolved -phase
analytical results, Apex will make recommendations regarding system reactivation, additional
groundwater monitoring events, and/or site risk reduction to achieve site closure.

1.0 INTRODUCTION
On behalf of Pilot Flying J (Pilot), Apex Companies, LLC (Apex) has completed semi-
annual groundwater monitoring activities associated with the soil and groundwater remediation
system located at the Pilot Travel Center #56, a retail gasoline station. In accordance with North
Carolina Department of Environmental Quality (NCDEQ) regulatory reporting requirements,
Apex has prepared a Corrective Action Monitoring Report for the subject property located at
2825 Lane Street in Kannapolis, North Carolina (Figure 1). This report includes semi-annual
groundwater sampling for the period beginning January 1, 2020 and ending June 30, 2021. Per
NCDEQ directives dated March 5, 2021, two additional soil borings were advanced between the
site and potable residential supply wells and converted to monitoring wells during this phase to
further assist in delineation of the gasoline plume.
The remediation system was installed by Apex in accordance with the NCDEQ-approved
Corrective Action Plan (CAP) to address the multiple -phase contaminants identified on the
subject property. A description of the remediation system design and function is presented in
Section 2.0. A site plan depicting pertinent features of the subject site and surrounding area is
provided as Figure 2. This report for semi-annual groundwater monitoring at the Pilot #56
facility is being submitted to Ms. Trudy Beverly of NCDEQ, on behalf of Pilot.
2.0 SITE HISTORY AND BACKGROUND
The site has been a working supplier of gasoline, diesel, and kerosene since at least 1984
and probably much earlier. From 1966 to 1972 the site was owned by the Humble Oil Company.
In 1972 the property owner became Exxon Corporation via a name change. Aerial photographs
obtained from Cabarrus County GIS department suggest that the site was a gas station by 1975.
It operated as a Starvin Marvin from 1984 and then Speedway America until October 26, 2001,
when Pilot Travel Centers, LLC purchased the property.
According to records reviewed by Apex, seven underground storage tanks (USTs) were
closed by removal in May 1994. The UST Closure Report also documented that two 12,000-
gallon USTs were removed from service in 1991. A list of current and historical USTs for the
site are provided in Table 1. The report also documented that there were releases associated with
both product lines and the southern UST tank basin. The release was assigned incident number
6379 by the North Carolina Department of Environment and Natural Resources (NCDENR).
The site was redeveloped and subjected to active remediation. Following 18 months of active
remediation, the incident was closed by NCDENR in 1998. Historical release information is
provided in Table 2.
In April 2006, a contractor mobilized to the site to gauge monitoring wells prior to
abandonment on behalf of the responsible party for incident 6379. The contractor reportedly
discovered light non -aqueous phase liquid (LNAPL) in RW-8 and MW-9. Follow-up
investigation in the tank areas and product lines failed to determine a new source. NCDENR
considered the LNAPL to be a new release and assigned incident number 36096.
CA Monitoring Report (Jan. 1 to June 30, 2021) 1 May 28, 2021
Pilot # 56
Incident#36096

Several phases of assessment have occurred since 2006. A site check on the south side of
the facility was performed which focused on soils around the new UST basin and the dispenser
lines. A total of 22 soil samples were collected for total petroleum hydrocarbons (TPH)
gasoline -range organics (GRO) analysis. Nine of the 22 soil samples were analyzed for TPH
diesel -range organics (DRO) as well. Four soil samples were reported with GRO concentrations
above the NCDENR UST action level of 10 milligrams per kilogram (mg/kg) at the time of the
investigation. DRO were detected in five of the soil samples above 10 mg/kg. A Phase II
Limited Site Assessment was conducted and submitted, and the site was assigned a "High Risk"
ranking by NCDENR. On February 20, 2009, NCDENR issued a Notice of Regulatory
Requirements requesting a Comprehensive Site Assessment (CSA) for the site.
A CSA was prepared for the site in December 2009 that delineated the dissolved -phase
groundwater concentrations vertically and horizontally. An additional round of sampling
conducted in September 2010 confirmed the previous delineation. The dissolved -phase
hydrocarbon plume did not extend beyond the site property line and the detected groundwater
analytes did not exceed the gross contaminant levels (GCLs). The site is ranked `high risk' due
to the presence of water supply wells located within a 1,000-foot radius of the source area. It is
important to note that all the identified supply wells are located hydraulically cross -gradient of
the site and over 425 feet from any exceedances of the North Carolina 15A NCAC 2L
groundwater standards (2L). Repeated sampling and analysis of the water supply wells have
never detected petroleum hydrocarbons in the samples collected since identification of the
release in June 2006. Potable water supply well locations and other receptors are identified on
Figure 3 corresponding to property owners, land use classifications, and other receptors as
documented in Tables 3, 4, and 5, respectively. Furthermore, sentinel wells such as MW-21,
MW-22, and MW-25 continue to indicate that the gasoline plume is confined to the original
source zone identified and described in both the CSA and approved CAP. Additional monitoring
wells MW-27 and MW-28 installed in April 2021 further documented the confinement of the
gasoline plume to the site. Monitoring well locations are depicted on Figure 4. Municipally
supplied potable water is available to area residents for connection.
Silty sands dominate the lithology at the site. Shallow soil on site is disturbed and very
heavily compacted. Bedrock was encountered at approximately 45 ft below land surface (bls) at
DMW-2. Shallow groundwater is encountered at approximately 22 ft bls in the developed
portion of the site and flows to the north-northwest. Geologic cross -sections prepared during
CAP development are included as Appendix A.
The product of concern is unleaded gasoline. The two primary analytes of concern are
methyl tertbutyl ether (MTBE) and benzene. Historically there were other exceedances of the 2L
standard, but there were no 2L exceedances in wells without having either benzene or MTBE
present above 2L standards. The source area was presumed as south of the building, near MW-
24. At the time of CAP development, the assumed dissolved -phase groundwater contaminant
plume across the site was approximately 180 feet long by 90 feet wide and 30 feet deep. Mass
balance calculations indicated that the MTBE mass in the aquifer prior to active remediation was
approximately 124 kilograms in groundwater.

Incident#36096

Based on the risk ranking for the site, corrective action objectives (CAOs) listed below
were established for each site media by NCDENR. The status of the site in achieving the
established CAOs are also noted. According to the North Carolina Administrative Code,
(NCAC) 15A 2L .0407 soil must be cleaned up to Maximum Soil Contaminant Concentrations
(MSCCs) for soil to groundwater or residential standards, whichever is lower. As documented in
the approved CAP, the CAOs for residential soil were achieved prior to CAP
implementation. The remediation design in the CAP addressed the nominal soil impact in the
southern area subsurface that remained above soil -to -groundwater standards. According to
NCAC 15A 2L .0202, surface water must be remediated to NCAC, 15A 2B standards (2B). The
2B standard for benzene was 70 µg/L. As documented in the approved CAP, the CAOs for
surface water at the site were achieved prior to CAP implementation as no measurable
surface water impact has been detected at the site. As such, remedial measures for stormwater
and surface water treatment were not carried forward in the CAP. According to NCAC 15A 2L
.0202, groundwater at the site must be remediated to the applicable 2L Standards which are 1.0
µg/L and 20 µg/L for benzene and MTBE, respectively.
The objective of the CAP was to maintain groundwater quality conditions at the site
below the applicable 2L Standards for benzene and MTBE while aggressively remediating
source area groundwater and minor soil impact. The corrective action approach to achieve the
aforementioned goals for groundwater at the site consisted of an engineered air sparging and soil
vapor extraction (SVE) system coupled with monitored natural attenuation. Air sparging is
effective in removing volatile hydrocarbon constituents, including MTBE from groundwater.
SVE captures volatile organic vapors from the subsurface and provides an increased pressure
gradient to enhance the efficacy of the air sparging. The end of active remediation will be
determined when asymptotic conditions are reached in dissolved hydrocarbon concentrations in
groundwater or when the applicable 2L standards have been achieved, or risk can be reduced. A
full description of the remediation system is provided below in Section 3.0.
CAP implementation at the site began in April 2012. Prior to CAP implementation seven
monitoring wells (MW-11, MW-12, MW-19, MW-21, MW-23, MW-24, and DMW-3) were
above the benzene 2L limit of 1.0 µg/L. The MTBE 2L limit of 20 µg/L was exceeded in eight
monitoring wells (MW-11, MW-14, MW-17, MW-19, MW-21, MW-23, MW-24, and DMW-3)
prior to CAP implementation. On December 12, 2017 Apex met with Department of
Transportation (DOT) staff and their consultant to inspect monitoring wells that were proposed
for abandonment during a road construction project at the site. As a result of the construction
project Apex turned off AS-5 supplying air to MW-18 pending abandonment by others.
Additional wells requiring abandonment for the construction project were MW-3 and MW-19.
At the conclusion of 2nd Quarter 2020 CAP implementation the dissolved -phase endpoint for
benzene of 1.0 µg/L was not exceeded in any monitoring wells. The dissolved -phase endpoint
for MTBE of 20 µg/L was exceeded in monitoring wells MW-14 and MW-23. Based on 2nd
Quarter 2020 analytical results of an average MTBE concentration across the site of 7.3 µg/L
and an average benzene concentration of 0.50 µg/L, mass balance calculations indicate the mass
of MTBE and benzene remaining in the aquifer are approximately 32 grams.

3.0 REMEDIATION SYSTEM
The SVE and air sparge remediation system at the Pilot #56 facility was successfully
activated on April 18, 2012. The SVE system consists of a Roots Universal RAI® 36 blower
(replaced February 2017) paired with a ten horsepower Baldor Electric motor. Together the
system module is capable of a maximum extraction rate of 195 actual cubic feet per minute
(ACFM) at a vacuum of 12.0 inches of mercury (in Hg). The air sparge system consists of a 15
horsepower "rotary screw" compressor capable of 44-cubic feet per minute (CFM) at 55.0
pounds per square inch (PSI). The complete system is housed in a mobile eight -foot by 16-foot
enclosed cargo trailer. The SVE manifold contains three "legs" capable of supplying a vacuum
at recovery locations SVE-1 through SVE-3. The remediation system layout with SVE well
locations is depicted on Figure 5. An air sparge manifold within the remediation system
enclosure includes individual gate valves, pressure gauges, pressure regulators, flow meters, and
check valves required to properly regulate air flow to allow for optimum treatment of the
identified subsurface petroleum constituents at air sparge points AS-1 through AS-16.
Activation activities included transportation of the turn -key system to the site and connection to
the sub -gradient infrastructure and separately metered power from other site activities. The
remediation system layout with air sparge well locations is depicted on Figure 6. In response to
NCDEQ directives dated August 8, 2019, the SVE and air sparge system components were
deactivated on August 14, 2019.
4.0 SUBSURFACE INVESTIGATION
4.1 Soil Boring Activities
Apex performed a subsurface investigation at the site on April 22, 2021 to assist
with further delineation of the gasoline plume at the site. Per NCDEQ directives dated
March 5, 2021 two additional soil borings were advanced between the site and potable
residential supply wells and converted to monitoring wells. Two soil borings were drilled
and converted to monitoring wells MW-27 and MW-28. The soil boring locations were
selected based on the location of the source area, potable supply wells, and NCDEQ
directives. Prior to advancement of the soil boring, Apex conducted a ground penetrating
radar (GPR) survey of the DEQ-approved area proposed for soil boring and monitoring
well installation. The GPR survey was conducted to assist with identifying private
utilities that are not marked in accordance with standard One Call Utility protocol. Apex
also utilized soft dig techniques to physically clear the boring to a depth of five feet.
Soil borings were drilled using a track -mounted Geoprobe drill rig equipped with
continuous -flight, hollow -stem augers with an internal diameter (I.D.) of 4.25 inches.
Hollow -stem auger drilling methods were utilized to collect split -spoon soil samples for
identification and to facilitate monitoring well construction upon completion of the
borings. Two-inch diameter, 24-inch long split -spoon samplers were used to collect
subsurface soil samples at five-foot minimum intervals during drilling. Drilling and split -
spoon sampling were conducted in accordance with ASTM-D-1586-87 protocol. Contact
downhole drilling equipment (hollow -stem augers, drill rods) was decontaminated prior
CA Monitoring Report (Jan. 1 to June 30, 2021) 4 May 28, 2021
Pilot # 56
Incident#36096

to drilling using a steam cleaner with a design discharge of 180°F. Sampling equipment
was decontaminated between each sample interval using a phosphate -free detergent
solution and water rinse. The borings were advanced to a depth of 30 feet. Disposable
latex gloves were used during all phases of sample collection. A soil boring log is
included as Appendix B. Drill cuttings generated during soil boring activities were
dispersed onsite in the vicinity of the boring locations and covered with grass seed and
straw. Per NCDEQ directives, soil samples were not collected during soil boring
advancement.
4.2 Groundwater Monitoring Well Construction
Apex completed the soil borings as monitoring wells MW-27 and MW-28. The
monitoring well locations are depicted on Figure 4. The groundwater monitoring wells
were installed to a depth of 30 feet to collect groundwater samples, perform aquifer
testing, and to monitor for the presence of free -phase petroleum product accumulation.
The groundwater monitoring well was constructed of two-inch I.D. schedule 40 PVC
casing and 0.010-inch factory -slotted well screen. All screen and casing was flush -
threaded and equipped with "O" rings to prevent leakage at joints. End caps for the
screened intervals consisted of threaded well points. The well is equipped with an
expansion -type locking well cap. The well annulus was filled with washed, #2 quartz
filter sand. Apex brought the sand pack up to approximately seven feet above the top of
the screened interval. A pelletized bentonite seal was placed above the sand filter pack
and hydrated with potable water. The remainder of the annulus was completed with neat
Portland grout and a flush -mount protective well cover cemented at the ground surface.
A monitoring well construction diagram is included on the boring logs provided as
Appendix B. The well was developed by the North Carolina licensed well driller at the
completion of monitoring well construction.
5.0 GROUNDWATER MONITORING
During this phase, Apex performed a semi-annual groundwater monitoring event to
assess water table elevations and current dissolved -phase contaminant levels. Pursuant to the NC
DEQ-approved CAP, Apex performed monitoring and sampling at monitoring wells MW-9,
MW-11, MW-12, MW-14, MW-17, MW-20, MW-21, MW-22, MW-23, MW-24, MW-25, and
DMW-3. Monitoring wells MW-27 and MW-28 were also sampled during this phase. On May
12, 2021, Apex used a Solinst' electronic interface probe to investigate for the presence of free
product and to measure groundwater elevations. Free product was not detected in any of the
groundwater monitoring wells gauged during this phase. Groundwater elevation data for the
gauging event is presented in Table 6. Groundwater flow at the site was determined by the
triangulation method of the relative groundwater elevations within the fourteen monitoring wells.
Figure 7 is a water table gradient map generated from the relative elevations of equilibrated
groundwater as measured on May 12, 2021. Relative groundwater elevations based on surveyed
top of casing elevations predict shallow groundwater flow is to the north-northwest, which is
consistent with previous investigations. Monitoring/recovery/air sparge well locations are

depicted on Figures 4, 5, and 6. Shallow groundwater flow direction is depicted on Figures 1, 3,
and 7.
Per NC DEQ directives, on May 12, 2021, Apex collected groundwater samples from
fourteen monitoring wells (MW-9, MW-11, MW-12, MW-14, MW-17, MW-20, MW-21, MW-
22, MW-23, MW-24, MW-25, MW-27, MW-28, and DMW-3). Prior to sampling, Apex purged
each well to remove suspended sediment from the water column and to collect samples
representative of aquifer conditions. Each well was purged until a minimum of three well
volumes had been displaced. Groundwater samples were collected using dedicated, disposable,
high -density polyethylene bailers and were transferred directly into the appropriate sample
containers immediately upon collection. The samples were stored on ice pending delivery to the
laboratory. Disposable, latex gloves were used during all phases of sample collection.
Groundwater samples were submitted to Pace National (Pace) in Mount Juliet, Tennessee for
volatile organic compound (VOC) analysis via U.S. EPA SW-846 method 6200B. Strict sample
security and chain -of -custody documentation were maintained during all phases of transport.
Analytical results yielded petroleum compounds in six of the fourteen monitoring wells sampled,
with a maximum MTBE concentration 36.8 µg/L in monitoring well MW-14. Benzene was not
detected in any monitoring wells above the laboratory method detection limit during this phase.
A summary of current groundwater quality data is presented in Table 7. Chain -of -custody
documentation and the laboratory Certificates of Analyses are included as Appendix C.
Historical groundwater analytical results are provided in Appendix D. The dissolved -phase
endpoint for MTBE of 20 µg/L was exceeded in monitoring well MW-14. Average analytical
results decreased as compared with previous sampling events. An isoconcentration map for
MTBE is provided as Figure 8. Trend graphs depicting benzene and MTBE concentrations over
time as compared to CAP endpoints are provided as Appendix E.
Per NC DEQ directives, on May 12, 2021, Apex also collected groundwater samples
from five of six supply wells (5922, 5925, 5927, 5955 Turkey Road and 2847 Lane Street). A
sample was not collected during this phase from 2865 Lane Street as no one was home at the
time of the site visit and there was no outside access to potable water. Supply well locations are
depicted on Figure 3. A list of property owners for the supply wells and land use classifications
are provided as Tables 3 and 4, respectively. The supply well samples were collected from
outdoor spigots after being purged for approximately ten minutes. Clean, disposable latex gloves
were used during all phases of sample collection. The samples were labeled and stored on ice
pending delivery to the laboratory. Supply well samples were submitted to Pace for VOC
analysis via U.S. EPA SW-846 method 6200B. Strict sample security and chain -of -custody
documentation were maintained during all phases of transport. Petroleum constituents were not
detected in any of the supply well samples; however, tetrachloroethene at a concentration of 1.89
µg/L was detected in supply well SW-5922, which was consistent with the previous sampling
events. Tetrachloroethene is typically associated with the use of solvents and could be the result
of some recent plumbing repairs at the residence. The laboratory Certificate of Analysis and
chain -of -custody records are provided as Appendix C.
The site is ranked `high risk' due to the presence of water supply wells located within a
1,000-foot radius of the source area. It is important to note that all the identified supply wells are
located hydraulically cross -gradient of the site (shallow groundwater flow is to the
CA Monitoring Report (Jan. 1 to June 30, 2021) 6 May 28, 2021

North/Northwest) and over 425 feet from any exceedances of the North Carolina 15A NCAC 2L
groundwater standards (2L). Repeated sampling and analysis of the water supply wells have
never detected petroleum hydrocarbons in the samples collected since identification of the
release in June 2006. Furthermore, sentinel wells such as MW-21, MW-22, and MW-25
continue to indicate that the gasoline plume is confined to the original source zone identified and
described in both the CSA and approved CAP. Additional subsurface investigations conducted
during this phase, including the installation of monitoring wells MW-27 and MW-28, further
documented that the gasoline plume is confined to the site.
Mass balance calculations were updated using May 2021 dissolved -phase groundwater
analytical results. The source area was presumed as south of the building, near MW-24. At the
time of CAP development, the assumed dissolved -phase groundwater contaminant plume across
the site was approximately 180 feet long by 90 feet wide and 30 feet deep (486,000 cubic feet).
Multiplying by 7.48 gallons per cubic foot equals a total volume of 3.6 million gallons. Using
30% porosity yields 1.1 million gallons of impacted groundwater above the 2L standard. Using
30,000 µg/L and 1,000 µg/L as average concentrations for MTBE and benzene, respectively,
mass balance calculations indicated that the MTBE mass in the aquifer was approximately 124
kilograms and the benzene mass was approximately four kilograms prior to CAP
Implementation. Based on 2nd Quarter 2021 analytical results of an average MTBE concentration
across the site of 5.1 µg/L and an average benzene concentration of 0.50 µg/L, mass balance
calculations indicate the mass of MTBE and benzene remaining in the aquifer are approximately
23 grams.
6.0 CORRECTIVE ACTION MONITORING REPORT SUMMARY
Apex has completed CAP monitoring activities associated with the Pilot #56 facility
located in Kannapolis, North Carolina for the period beginning January 1, 2021 and ending June
30, 2021. At the conclusion of 2nd Quarter 2021 CAP implementation there was no measurable
free -phase petroleum product at the site and the benzene 2L CAP endpoint was not exceeded in
any monitoring wells sampled. Monitoring well MW-14 exceeded the MTBE 2L CAP endpoint.
Average analytical results decreased across the site as compared with previous sampling events.
Petroleum compounds have never been detected in any of the area potable water supplies and
sentinel wells such as MW-21, MW-22, and MW-25, along with new monitoring wells MW-27
and MW-28, continue to indicate that the gasoline plume is confined to the original source zone
identified and described in both the CSA and approved CAP.
Mass balance calculations presented in this report indicate that the mass of MTBE and
benzene remaining in the aquifer are approximately 23 grams in groundwater, down from
approximately 32 grams at the conclusion of 2nd Quarter 2020 monitoring. Apex recommends
initiating post -CAP monitoring of the site for the following reasons:
• Mass balance calculations of remaining benzene and MTBE at the site show
approximately 23 grams of combined MTBE and benzene remain onsite as a
result of the incident. Additionally, a mass reduction for MTBE and benzene of
99.95% has been accomplished with the remediation system.
CA Monitoring Report (Jan. 1 to June 30, 2021) 7 May 28, 2021
Pilot # 56
Incident#36096

• Absence of measurable dissolved -phase petroleum compounds in area water
supply wells since source identification in June 2006.
• Absence of measurable dissolved -phase petroleum concentrations in sentinel
wells, MW-21, MW-22, MW-25, MW-27, and MW-28.
• Direction of shallow groundwater flow to the North -Northwest, which is cross -
gradient from potable water supplies.
• Presence of municipally supplied potable water to many of the area businesses
and residences.
Apex recommends continued system deactivation and an additional groundwater
monitoring event in November/December 2021 to continue observing dissolved -phase trends in
groundwater after system activation. Based on November/December 2021 dissolved -phase
analytical results, Apex will make recommendations regarding system reactivation, additional
groundwater monitoring events, and/or site risk reduction to achieve site closure. This report,
prepared in accordance with NCDEQ-approved scope of work, is being submitted to Ms. Trudy
Beverly of NCDEQ on behalf of Pilot.

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
CID
IID
FTC
FSS
MDL
Method Detection Limit.
ND
Not detected at the Reporting Limit (or MDL where applicable).
rCn
RDL
Reported Detection Limit.
Rec.
Recovery.
FSr
RPD
Relative Percent Difference.
SDG
Sample Delivery Group.
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
6
QC
(S)
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.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
a
Dilution
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.
FSC
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
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.
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"
Result
(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.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
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
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
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.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
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.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
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
The remainder of this page intentionally left blank, there are no qualifiers applied to this SDG.

Attached is the CAP Monitoring Report for the Pilot 56 facility which included the install of the 2 additional MWs.
As you will see the MWs confirmed the confinement of the plume to the site.
I did recommend additional sampling late this year to confirm.
Please let me know if you have any questions or need anything else at this time.
Have a great long weekend.
Thanks,
Robert
