EXECUTIVE SUMMARY
Handy Stop #7 is located at 1500 Rock Barn Road in Conover, Catawba County, North Carolina The site is
currently owned and operated by C.C. Royal Enterprises, LLC as a petroleum retail facility and convenience
store. According to the North Carolina Registered Tank database, three 10,000-gallon gasoline USTs, one
5,200-gallon diesel UST and one 5,200-gallon kerosene UST are in use at the site. According to historical
information from the previous consultants, a release was discovered in March 2006 during a Phase II ESA.
The site and surrounding area are primarily commercial and residential. According to the 2013 update to
the receptor survey, a total of fourteen water supply wells were identified within 1,500 feet of the subject
site. There are five non-potable water supply wells located within 1,000 feet of the site. Public water is
available to the site and surrounding properties within 1,500 feet of the site.

In accordance with the 2009 CAP and 2016 system redesign, an AS and SVE system was installed at the
site and activated on February 20, 2018. The system installation included the installation and connection
of a total of five AS wells and six SVE wells throughout the contaminant plume. The May 2017 ground
water sampling data was used to establish the baseline contaminant mass for each area of the plume.
Overall, it is estimated that approximately 58,349 grams of contamination were present at the site during
the baseline sampling event. No projected milestones were established in the CAP.

O&M site visits were conducted on June 21, July 25, and August 25, 2022. Hour meter, system vacuum,
pressure, air flow and temperature, AS well pressure, and SVE well vacuum readings were collected during
each site visit. Additionally, SVE effluent air samples were collected during the June, July, and August
2022 site visits and submitted for laboratory analysis. Please note that due to the lab transferring the July
2022 air sample to a different facility, the hold time elapsed and the sample could not be analyzed.

The concentrations reported from the May 2017 sampling event were used as a baseline for contaminant
mass calculations. Based on the May 2017 sampling event, the contaminant plume was divided into four
areas (Areas #1 (MW-4), #2 (OW-2), #3 (OW-1) and #4 (MW-1R and MW-8)) based on the proximity to
impacted monitoring wells to determine the baseline contaminant mass at the site. Calculations based
on the April 5, 2022 ground water sampling event indicate that the contaminant mass has decreased by
75.6%, 4.3%, 88.0% and 76.7% in Areas 1 through 4, respectively, when compared to the baseline sampling
event. The contaminant concentrations in Areas 1 through Area 4 have generally decreased over time;
however, Area 2 has intermittently contained free product. The overall contaminant mass at the site has
decreased by approximately 30.2% from the May 2017 sampling event to the April 2022 sampling event.

Based on the results of the April 2022 ground water sampling event and the municipal water connection
for the property containing WSW-3 in July 2021, GRI recommends the risk ranking for the site be lowered
to intermediate. GCL exceedances remain in telescoping well DW-2 and OW-2; however, the remediation
system was not designed to address deep contamination. GRI is gathering information about potential
injection technologies to address the contamination in DW-2; however, some of the options are still in
the process of getting approved as an approved innovative technology. Semi-annual ground water
monitoring should continue for telescoping well DW-2 and observation well OW-2; while annual ground

water monitoring should be conducted on wells MW-1R, MW-3, MW-4, MW-8 through MW-10, OW-1,
and DW-1 through DW-3 to monitor for potential rebound of contaminant concentrations. Based on the
April 2022 sampling event, contaminant concentrations in OW-2 rebounded; therefore, continued
operation of the remediation system is recommended until concentrations in OW-2 are reduced to below
the GCLs. The next semi-annual ground water sampling event for TW-2 and OW-2 is scheduled tentatively
for April 2023.

1.0 SITE HISTORY AND CHARACTERIZATION
GRI presents the results of ongoing O&M activities conducted between June and August 2022 at the
Handy Stop #7 site; located at 1500 Rock Barn Road in Conover, Catawba County, North Carolina (Figure
1). These activities were conducted in accordance with GRI Proposal No. 22-396, which was submitted to
the NCDEQ on June 3, 2022, and approved as Task Authorization No. 36069-59 on June 9, 2022. State
correspondence is included Appendix A.

The site is currently owned and operated by C.C. Royal Enterprises, LLC as a petroleum retail facility and
convenience store. According to the North Carolina Registered Tank database, three 10,000-gallon
gasoline USTs, one 5,200-gallon diesel UST and one 5,200-gallon kerosene UST are in use at the site.
According to historical information from the previous consultants, a release was discovered in March 2006
during a Phase II ESA. UST owner/operator information and UST system information are included as
Tables 1 and 2, respectively. The Registered Tank Report is shown below:

The site and surrounding area are primarily commercial and residential. The site contains three buildings
(the convenience store, a carwash and the remediation system building) and is primarily capped with
concrete and asphalt. No surface water bodies were identified within a 500-foot radius of the site and
the closest surface water body being an unnamed tributary of Mull Creek, located approximately 800 feet
southeast of the site. During previous assessment and remediation activities, ten Type II monitoring wells
(MW-1R and MW-2 through MW-10), three Type III telescoping wells (DW-1 through DW-3), two
observation wells (OW-1 and OW-2), five air sparging wells (AS-1 through AS-5) and six vapor extraction
wells (SVE-1 through SVE-6) were installed at the site. Monitoring wells (MW-1R and MW-2) are 4”
recovery wells. Monitoring well MW-3’s well casing was previously damaged at grade level and was
repaired during the February 2019 site visit. A Site Map showing the locations of the monitoring wells
and the structures on-site and on surrounding properties has been included as Figure 2.

The site is located in the Piedmont Physiographic Province of North Carolina. The soils in the area are the
result of in-place weathering of the underlying bedrock, except along stream valleys where the soils are
comprised of alluvial materials and their weathered products. The water table has a seasonal high depth
to water of approximately 29 to 36 feet bgs.

An update to the receptor survey was conducted in January 2013. A total of fourteen water supply wells
were identified within 1,500 feet of the subject site. There are five non-potable water supply wells located
within 1,000 feet of the site. In July 2021, the property associated with water supply well WSW-3 was
connected to the public water supply. WSW-3 is currently used for non-potable uses only. Public water
is available to the site and surrounding properties within 1,500 feet of the site. Adjacent property owner
information and water supply well information based on the 2013 receptor survey update is presented in
Tables 3 and 4, respectively. A Site Vicinity Map showing the location of the water supply wells has been
included as Figure 3.

Please note that the historical information contained in this report was obtained under the supervision of
the previous consultants. Although GRI cannot verify the accuracy of the information obtained by
previous consultants, for the purpose of this report it is assumed to be correct and any inferences or
interpretations made by GRI based on data that may be incorrect are not the responsibility of GRI. Please
refer to earlier submittals for additional information regarding previous assessment activities.
2.0 FREE PRODUCT REMOVAL
Free product was historically present in monitoring wells MW-1R, MW-3 and OW-2. To date, six MMPE
events have been conducted at the site. A total of approximately 18,052.30 gallons of contaminated
ground water and free product have been removed from the site. No free product has been identified
since the January 2020 sampling event.
3.0 REMEDIATION SYSTEM
In accordance with the 2009 CAP and 2016 system redesign, a SVE and AS system was installed at the site
and activated on February 20, 2018. The system installation included the installation and connection of a
total of five AS wells and six SVE wells throughout the contaminant plume. A map showing the locations
of the remediation wells is included as Figure 4.

O&M site visits were conducted on June 21, July 25 and August 25, 2022. Hour meter, system vacuum,
pressure, air flow and temperature as well as AS well pressure and SVE well vacuum readings were
collected during each of the site visits. Additionally, SVE effluent air samples were collected during each
site visits and submitted for laboratory analysis. Please note that due to the lab transferring the July 2022
air sample to a different facility, the hold time elapsed and the sample could not be analyzed.

The SVE system operated for a total of 383 hours and the system vacuum ranged from 1.7 to 2.1 inches
of Hg during the current quarter of O&M (June through August 2022). The AS system operated for a total
of 280 hours during the reporting period with system pressures ranging from 14.5 to 17.0 psi. Please refer

to the individual O&M data sheets for additional system measurements. System flows were adjusted as
needed. General condition of the system was also noted.

Based on the recommendations in the previous report and a phone conversation with Mr. Brad Newton
of the NCDEQ on January 7, 2022, the remediation system was shut down and winterized during the
January 2022 site visit. The remediation system was restarted in June 2022 following a rebound in
contaminant concentrations in OW-2. Work conducted during the site visits along with hour meter
readings is summarized in Table 5. O&M Field data sheets are included as Appendix B.
4.0 AIR SAMPLING
Air samples were collected from the exhaust of the SVE system on June 21, July 25 and August 25, 2022.
Please note that due to the lab transferring the July 2022 air sample to a different facility, the hold time
elapsed and the sample could not be analyzed. A summary of the analytical results for air samples
collected during the current quarter of system operation is presented in Table 6. Complete reports of
laboratory analyses have been included as Appendix C. A summary of air sampling results during the
current quarter is shown below:

5.0 SOIL AND GROUND WATER REMEDIATION
The May 2017 ground water sampling event was used as the baseline event per the direction of the
NCDEQ. Based on the May 2017 Benzene Isoconcentration Map, the contaminant plume was broadly
divided into four areas based on their proximity to the target wells (MW-1R, MW-4, MW-8, OW-1, OW-2
and AS-1 through AS-5) in order to determine the baseline contaminant mass at the site. Areas #1 (MW-
4), #2 (AS-2 and OW-2), #3 (AS-3 and OW-1) and #4 (MW-1R, MW-8, AS-1, AS-4 and AS-5) are
approximately 2,975 square feet, 6,517 square feet, 4,116 square feet and 4,373 square feet, respectively.
Historical ground water gauging data was used to establish the height of the water column. For each area,
the shallowest depth to ground water was used to estimate the total volume of the contaminant plume.

The total volume was then multiplied by the effective porosity in order to calculate the total effective
volume for each area. A map showing the estimated contaminant mass areas has been included as Figure
5.

Available historical data for the site was reviewed in order to develop a strategy for measuring
remediation progress against an established baseline for the contaminant plume. To calculate
contaminant mass present at the site, the following three avenues of contaminant migration/source were
evaluated as well as the data required for each source. The calculations were revised to estimate the
influence of fluctuations in ground water elevation.

Contamination present in ground water: The May 2017 ground water sampling data and total BTEX, MTBE
and naphthalene constituents were used to determine the baseline contaminant mass in each area. Area
#1 had approximately 3.57 grams of contaminant mass; Area #2 had approximately 36,954.63 grams of
contaminant mass; Area #3 had approximately 13,116.70 grams of contaminant mass and Area #4 had
approximately 8,274.37 grams of contaminant mass, respectively.

Calculations based on the April 5, 2022 ground water sampling event indicate that the contaminant mass
has decreased by 75.6%, 4.3%, 88.0% and 76.7% in Areas 1 through 4, respectively, when compared to
the baseline sampling event. The contaminant concentrations in Areas 1 through Area 4 have generally
decreased over time; however, Area 2 has intermittently contained free product. The overall contaminant
mass at the site has decreased by approximately 30.2% from the May 2017 sampling event to the April
2022 sampling event. A significant rebound of 166.7% was observed in Area 2 from the October 2021
sampling event to the April 2022 sampling event. Change in contaminant mass calculations and
Contaminant Concentration vs. Time Graphs have been included as Appendix E. A chart depicting the
overall trend in contaminant mass, and the change in average water column depth over time is shown
below:

1. Contamination due to leaching effect from unsaturated soils: Soil quality data from the former
source areas as well as from the vicinity of the above referenced source area monitoring wells is
not available. Therefore, it is not possible at this point to factor in the effect of this potential on-
going source of ground water contamination. However, since the water table surface is much
shallower than during the baseline event, it is likely that contaminant leaching from previously
unsaturated soils is contributing to increases in contaminant mass. If soil sampling is deemed
necessary for the calculation of any secondary source inputs, they will be proposed at a later date.
2. Contamination input due to the presence of free product: Free product was observed in
observation well OW-2 during the August 2018, October 2018, January 2019, April 2019, July
2019, and January 2020 ground water sampling events and prior to the September 2019 MMPE
event and the site has had a history of free product in the past. Free product was also observed
in MW-3 during the February 2019 ground water sampling event. If free product is observed at
the site in future sampling events, free product removal should be continued in order to reduce
the effects of free product acting as a secondary source of ground water contamination.

• Collect a ground water sample from telescoping well DW-1 and observation well OW-2 on a semi-
annual basis since the contamination concentrations in DW-1 and OW-2 remain above the GCLs.
• Include a comprehensive ground water sampling event that includes wells MW-1, MW-3, MW-4,
MW-8 through MW-10, OW-1, OW-2 and DW-1 through DW-3 on an annual basis to monitor for
rebound and downgradient migration.
• Conduct soil sampling on an as needed basis.

Performance Monitoring:
• The remediation system was restarted in June 2022. Monthly O&M visits are recommended to
monitor the system and adjust flows as needed.

The contaminant concentrations in Areas 1 through Area 4 have generally decreased over time; however,
Area 2 has intermittently contained free product. Semi-annual ground water monitoring should continue
until remediation options for DW-2 have been evaluated. Milestones and a time frame for completion of
remediation goals for the site can be estimated once remediation has been established.

6.0 CONCLUSIONS
• The remediation system was restarted in June 2022 at the direction of the NCDEQ. Three site visits
were conducted during the current quarter of O&M. Air samples were collected during the June
21, July 25, and August 25, 2022 O&M site visits. Please note that due to the lab transferring the
July 2022 air sample to a different facility, the hold time elapsed and the sample could not be
analyzed.
• Calculations based on the April 5, 2022 ground water sampling event indicate that the contaminant
mass has decreased by 75.6%, 4.3%, 88.0% and 76.7% in Areas 1 through 4, respectively, when
compared to the baseline sampling event. The contaminant concentrations in Areas 1 through
Area 4 have generally decreased over time; however, Area 2 has intermittently contained free
product.
• Based on the results of the April 2022 ground water sampling event and the municipal water
connection for the property containing WSW-3 in July 2021, GRI recommends the risk ranking for
the site be lowered to intermediate. GCL exceedances remain in telescoping well DW-2 and OW-
2; however, the remediation system was not designed to address deep contamination. GRI is
gathering information about potential injection technologies to address the contamination in DW-
2; however, some of the options are still in the process of getting approved as an approved
innovative technology. Semi-annual ground water monitoring should continue for telescoping well
DW-2 and observation well OW-2; while annual ground water monitoring should be conducted on
wells MW-1, MW-3, MW-4, MW-8 through MW-10, OW-1, and DW-1 through DW-3 to monitor
for potential contaminant rebound. Based on the April 2022 sampling event, concentrations in
OW-2 rebounded; therefore, continued operation of the remediation system is recommended
until concentration in OW-2 are reduced to below the GCLs. The next semi-annual ground water
sampling event for TW-2 and OW-2 is scheduled tentatively for April 2023.

7.0 LIMITATIONS
This report has been prepared for the exclusive use of Shell Brothers Distributors, Inc. and NCDEQ for
specific application to the referenced site in Catawba County, North Carolina. The assessment was
conducted based on the scope of work and level of effort desired by the NCDEQ and with resources
adequate only for that scope of work. Our findings have been developed in accordance with generally
accepted standards of environmental practices in the State of North Carolina, available information, and
our professional judgment. No other warranty is expressed or implied.

The data that is presented in this report is indicative of conditions that existed at the precise locations

CHANGE IN CONTAMINANT MASS CALCULATIONS
HANDY STOP #7 (INCIDENT NO. 36069)
Baseline Event
0.20
Note:
• In areas containing free product, the last known contaminant mass without free product is used to calculate the total contaminant mass calculations.
• The air sparging wells have not been included in the total contaminant mass calculations due to the inability to sample the air sparging wells during future ground water sampling events.
• The telescoping wells have not been included in the total contaminant mass calculations due to the inability to calucate a volume.
• The percentage reduction for areas containing free product cannot be caluclated.
