2.0 EXECUTIVE SUMMARY
The McCain Grocery (aka Former McCain Grocery) site is located at 10018
Lancaster Highway, Waxhaw, Union County, North Carolina. Five underground
storage tanks (USTs) were previously operated at the site. One 1,000-gallon gasoline, one 550-gallon gasoline, one 280-gallon kerosene, and two 520-gallon gasoline USTs were removed from the site in 2005. A petroleum release was discovered during tank closure activities.

The purpose of this report is to document the latest remediation injection and groundwater sampling events. AST Environmental, Inc. (AST) provided BOS 200®+ (BOS) injection services at the site. These activities were conducted from June 5 through 21, 2023. Based on the Injection Summary Report, AST injected a total of
16,900 pounds (lbs) of BOS200®+ into 25 injection points in “Area A” and 8,400 lbs of BOS200®+ into 32 injection points in “Area C”. CATLIN Engineers and Scientists (CATLIN) personnel met the AST team on site on June 6 and 20, 2023 to observe the initial and final days of the injection activities.
On June 28, 2023, CATLIN personnel returned to the site for the one week post-injection sampling event. During the June 28 site activities, CATLIN measured groundwater at an average of approximately 38.4 feet deep across the site. Groundwater samples from three monitoring wells (MW-1R, MW-2, and MW-6) were collected. The samples were submitted to the Remediation Products, Inc. (RPI)
Project Support Laboratory for laboratory analysis of volatile organic compounds (VOCs) and total volatile petroleum hydrocarbons (TVPH) per Environmental Protection Agency (EPA) Method 8260B, Anions per EPA Method 300.1, and dissolved gasses per Method RSK-175.
On July 24, 2023, CATLIN personnel returned to the site for the second of two post-
injection sampling events (5-weeks post-injection). During the July 24 site activities, CATLIN measured groundwater at an average of approximately 38.5 feet deep across the site. Groundwater samples from the same three monitoring wells were collected. The samples were again submitted to RPI for laboratory analyses as
detailed above.
Laboratory results for VOC analyses indicated the presence of many dissolved petroleum constituents in the samples from wells MW-2 and MW-6 at concentrations greater than those established in Title 15A of the North Carolina Administrative
Code, Subchapter 2L, Section .0202 Groundwater Quality Standards (2L GWQS) in
both the one week and 5-weeks post-injection samples. However, no targeted analytes exceeded their respective Gross Contaminant Levels (GCLs) in any of the monitoring well samples.
Review of the baseline sampling event (June 6, 2023) and the 5-weeks post
injection sampling event (7/24/2023) revealed the following reductions of TVPH and benzene concentrations in monitoring wells MW-1R, MW-2 and MW-6:
NCDEQ; 27981_McCain Grocery CATLIN Engineers and Scientists

Well ID TVPH Reduction
(%)
Benzene Reduction
(%)
MW-1R >99 % >99.9
MW-2 +18.2 % (increase) 26.3
MW-6 97 % 99.7

It should be noted that 1,2-dibromoethane (EDB) was detected above the GCL in the MW-1R sample collected in March 2023; however, EDB was not analyzed during the baseline or any of the post injection sampling events.
CATLIN recommends continuing with quarterly monitoring and sampling events for
the first year following the injection. The next event should be conducted in November 2023. Samples should be sent to a North Carolina certified laboratory to be analyzed per SM 6200 and also sent to RPI to be analyzed as specified by AST.

NCDEQ; 27981_McCain Grocery CATLIN Engineers and Scientists
CATLIN Project No. 223071 4 October 2023
4.1 UST OWNER AND OPERATOR INFORMATION The tank owner and operator are unknown. The site was accepted into the
North Carolina UST Section Trust Fund Branch State Lead Program in 2005.
4.2 UST INFORMATION One 1,000-gallon gasoline, one 550-gallon gasoline, two 520-gallon gasoline,
and one 280-gallon kerosene USTs were previously operated on-site. The
installation and operation dates of the tanks are unknown. The tanks and product lines were removed from the site in September 2005. The dispenser pumps were removed prior to tank removal (Solutions, 2005).
Available UST system information is presented in Table 1 and the
approximate former UST system locations are illustrated on Figure 3. 4.3 CONTAMINANT SOURCE INVENTORY
An on-site release was discovered in 2005 during UST removal activities.
Soil sample analytical results revealed total petroleum hydrocarbons (TPH) above State Action Levels and VOCs above Soil-to-Groundwater (STGW) Maximum Soil Contaminant Concentrations (MSCCs) (Solutions, 2005).
4.4 SITE CHARACTERISTICS
The former store building was removed from the site. The property is currently owned by Richard and Karen Bronson and is occupied by an unknown resident. The parcel is comprised of the residence building, grass,
and several mature trees. Site photographs are presented in Appendix B.
4.5 OWNERS AND OCCUPANTS OF ADJOINING/NEARBY PROPERTIES AND LAND USE
Properties in the site vicinity are mostly residences and wooded land. The
site is bound by Lancaster Highway to the east. Residences adjoin the site to the north, south, and east across Lancaster Highway. Undeveloped land adjoins the site to the west, bounded by Tirzah Church Road on the opposite side.

Another UST Incident (No. 27776) is located on the adjacent property to the north. The Best Stop #2 site is a former gas station. 4.6 RECEPTOR INFORMATION

Conducting a receptor survey was outside the scope of this monitoring event. A review of historical files available on the NCDEQ Waste Management Online Database (aka Laserfiche) indicates that the last receptor survey for
NCDEQ; 27981_McCain Grocery CATLIN Engineers and Scientists
CATLIN Project No. 223071 5 October 2023
the McCain Grocery site was conducted in 2022 by Terracon Consultants, Inc. (Terracon).
According to previous reports, municipal water is not available to the site
vicinity. Eighteen water supply wells have been identified within 1,500 feet of the site. An active potable well (WSW-1) is located on-site, approximately 149 feet from the source area. Another active potable well (WSW-3) is located 375 feet from the site and an unconfirmed well (WSW-2) may be
located 384 feet from the site. Ten active potable wells are located between
500 to 1,000 feet from the site, and an additional five are located more than 1,000 feet. Three surface water bodies are located within 1,500 feet of the site. A pond is
located approximately 850 feet east of the site. Unnamed tributaries of
Simpson Branch and Keener Branch (both Class C surface water bodies) are located 1,450 feet east and 850 feet west of the site, respectively. Potential receptors are illustrated on Figure 2 and receptor information
obtained from Terracon (2022) is shown in Table 2.
4.7 PREVIOUS INVESTIGATIONS AND REMEDIAL ACTIVITIES The release was discovered in 2005 during UST closure activities by
Solutions Industrial and Environmental Services, Inc. (Solutions-IES). Soil
samples obtained from below UST-3, -4, and -5 as well as under the former gasoline and kerosene dispensers, contained TPH diesel range organics (DRO) concentrations up to 290 milligrams per kilogram (mg/kg). TPH gasoline range organics (GRO) were reported at 1,700 mg/kg below UST-3.
Multiple VOCs were above their STGW MSCCs in the sample from UST-3
(Solutions, 2005). Hart & Hickman, PC (H&H) performed a Phase I Limited Site Assessment (LSA) in 2006. The site was determined to be ranked as high risk, residential
due to no municipal water being available in the area and all properties assumed to have active potable water supply wells. A monitoring well (MW-1) was installed and two soil samples [13-15 feet below land surface (BLS) and 28-30 feet BLS] were collected from the boring and analyzed for VOCs, semi-VOCs, extractable petroleum hydrocarbons (EPH), and volatile petroleum
hydrocarbons (VPH). Multiple targeted analytes were detected above their respective STGW MSCCs in both samples; however, none were above Residential or Industrial/Commercial MSCCs. Groundwater samples were collected from on-site monitoring MW-1, a monitoring well from the adjacent Best Stop #2 site (MW-4), and three water supply wells (WSW-2, WSW-3,
and WSW-4). Multiple VOCs were detected in both monitoring well samples above their 2L GWQS. Benzene was reported at a concentration of 23,000 micrograms per liter (µg/L) in the MW-1 sample above its GCL of 5,000 µg/L. Lead was also detected in MW-1 (199 µg/L). Chloroform was detected in the
NCDEQ; 27981_McCain Grocery CATLIN Engineers and Scientists
CATLIN Project No. 223071 6 October 2023
WSW-4 sample above the method detection limit, but well below the 2L GWQS (H&H, 2006).
Multiple groundwater monitoring events have been conducted by various
parties between 2006 and 2021. To date, six monitoring wells are viable for sampling on-site. Targeted analytes have historically not been detected above their 2L GWQS in samples from MW-5 and MW-10. Dissolved phase petroleum constituents at concentrations above 2L GWQS have persisted in
samples from MW-1R, MW-2, MW-3, and MW-6. LNAPL has been previously
measured in monitoring wells MW-1 and MW-6. Benzene, EDB, and/or 1,2-dichloroethane (1,2-DCA) have been detected at concentrations above GCL in samples from MW-1R and MW-6 (Terracon, 2021).
Regular water supply well sampling events have also been performed in the
site vicinity. Benzene and/or EDB have been detected above 2L GWQS in samples from WSW-4, WSW-5 (Influent), WSW-8, and WSW-16. Bromodichloromethane was also detected above its 2L GWQS in the sample collected from WSW-17 in 2021 (Terracon, 2021).

Progress Environmental, Inc. (Progress) conducted soil sampling in 2011 as part of a Source Investigation Report. Ten soil borings (S-1 through S-10) were advanced up to 30 feet BLS for sample collection. The samples were analyzed for VOCs, semi-VOCs, and EPH/VPH. Petroleum-related
compounds were detected above their STGW MSCCs in nine of the soil
samples and above Residential MSCCs in three samples. The samples with the highest contamination concentrations (S-1, S-8, and S-9) were in the vicinity of the former dispenser island (Progress, 2011).
In February 2016, Terracon oversaw the removal of approximately 300 tons
of the previously identified petroleum impacted soils. Soil samples were collected from each sidewall and the bottom of the excavation. The sidewall samples were analyzed for TPH, and both GRO and DRO were reported above the State Action Levels in all samples. Multiple VOCs, semi-VOCs,
and EPH/VPH were detected in the bottom sample above their respective
STGW MSCCs. All VPH were above their Residential MSCCs in the bottom sample, but below Industrial/Commercial MSCCs (Terracon, 2016). Terracon coordinated a mobile multi-phase extraction event (MMPE) in
November 2019. The event lasted for a duration of 96 hours utilizing
monitoring wells MW-1R and MW-6 as the extraction points. A total of 4,791 gallons of impacted groundwater and LNAPL were removed, and 24.04 equivalent gallons of petroleum vapors were emitted (Terracon, 2019).
A Remedial Design Characterization (RDC) investigation was conducted by Terracon and AST, beginning on November 8, 2022. AST completed a Quantitative High Resolution Site Characterization (QHRSC) and recommended a BOS 200® injection program (Terracon, 2023).

CATLIN Project No. 223071 7 October 2023
Summarized available historical sampling and gauging data from previous consultants are provided in Appendix A.
CATLIN conducted a groundwater sampling event in March 2023.
Groundwater samples were collected from six monitoring wells (MW-1R, MW-2, MW-3, MW-5, MW-6, and MW-10) and seven water supply wells [WSW-1, WSW-4, WSW-5 (pre-treatment, post-treatment, and fridge tap), WSW-6, WSW-7, WSW-8, and WSW-16]. Laboratory results did not indicate
any dissolved petroleum constituents above their respective laboratory
reporting limits in the samples from MW-5 and MW-10. One or more VOCs were detected in the MW-1R, MW-2, MW-3, and MW-6 samples at concentrations above their respective 2L GWQS. Benzene and EDB were detected above their GCLs in the sample from MW-1R. No targeted analytes
were detected in the samples WSW-1, WSW-4, WSW-5 (pretreatment), and
WSW-5 (fridge). Low or estimated concentrations of targeted analytes were reported in the WSW-4, WSW-6, WSW-5 (post-treatment), WSW-7, WSW-8, and WSW-16 samples; none of these detections were above their respective 2L GWQS. Benzene was reported in the WSW-16 sample above 2L GWQS.
Contaminant concentrations had generally decreased in MW-1R and MW-6
since the October 2021 sampling event (CATLIN, 2023). 5.0 REGIONAL AND SITE GEOLOGY AND HYDROGEOLOGY
5.1 SOIL AND BEDROCK
As defined in the Geologic Map of North Carolina, published by the North Carolina Department of Natural Resources and Community Development (1985), the site lies within the Piedmont physiographic province.
The site is underlain by a felsic metavolcanic rock formation within the Carolina Slate Belt metamorphic rocks. According to the 1985 Geologic Map of North Carolina, metamorphosed flows and tuffs interbedded with mafic and intermediate volcanic rock, meta-argillite, and metamudstone crop out in the
site area. Boring logs provided in Terracon (2018) indicate that red/orange silty clay is present to approximately 10 feet BLS. Red/orange clayey silt was encountered from approximately 10 to 25 feet BLS. Brown to grey clayey silt
was observed from 25 to 35 feet BLS, and brown to grey silty sand was noted at further depths up to 48 feet BLS. 5.2 HYDROGEOLOGY
Groundwater - The 2020 Visual Hydrogeologic Framework (VHF) – North Carolina Hydrogeological Database did not identify sufficient boreholes near the site to draw a cross-section.
NCDEQ; 27981_McCain Grocery CATLIN Engineers and Scientists
CATLIN Project No. 223071 8 October 2023
Reports on file (by others) indicate the water table ranges from roughly 30 feet to 45 feet BLS. Saturated and capillary fringe saprolite soils vary from clayey silts/silty clays to silty sands. A southwesterly groundwater flow
direction has consistently been calculated and illustrated on historical figures.

Surface Water – Three surface water bodies (one pond and two tributaries) were identified within 1,500 feet of the site. According to the NCDEQ North Carolina Surface Water Classifications GIS viewer, the Simpson Branch and
Keener Branch are identified as Class C surface water bodies.
6.0 SITE ASSESSMENT INFORMATION CATLIN conducted all field activities in general accordance with the approved TAs.
Upon each arrival at the site, potential hazards were evaluated before beginning
field work and are documented on electronic Job Hazard Analysis (JHA) forms and Daily Activities Logs. The JHA forms and the Daily Activities Logs are included in Appendix C. Photographs from the site visits are included in Appendix B.
AST performed a series of injections across the impacted areas of the site between
June 5 and 21, 2023. CATLIN personnel were on site on June 6 and 20 to observe the beginning and end of the injection process. CATLIN personnel returned to the site and gauged and collected groundwater
samples from monitoring wells MW-1R, MW-2, and MW-6 at approximately one-
week (June 28, 2023) and five-weeks (July 24, 2023) post-injection. The samples were sent to RPI for analysis of VOCs and TVPH per EPA Method 8260B, Anions per EPA Method 300.1, and dissolved gasses per Method RSK-175. Well locations and site features are shown on Figure 3 and well construction details are presented
in Table 3.
6.1 REMEDIATION INJECTION OF BOS 200® + SOLUTION AST performed the BOS 200®+ injections at the site. Prior to initiating the
remedial process, AST was on site to complete pre-injection sampling of
selected wells. Two remedial injection areas, designated Area A (approximately 1,400 square feet with 25 points) and Area C (approximately 1,595 square feet with 29 points), were set up with a grid spacing of approximately 7.5 feet and a vertical injection interval of 30 to 50 feet below
ground surface (BGS) in Area A and 42 to 50 feet BGS in Area C. Prior to
injecting, AST collected “baseline” groundwater samples from MW-1R, MW-2, and MW-6 on June 6, 2023. Following sampling, the injections were completed in a staggered sequence of every other point in a row and skipping a row as work progressed to facilitate hydraulic loading and to allow
time for the injected solution to be assimilated. AST used a “top down”
injection strategy to ensure more comprehensive coverage of the vertical area. AST was on site from June 5 through 21, 2023 to complete the activities. Complete information concerning the equipment used, injection point spacing, injection pressure, rate of pumping, and additional process
NCDEQ; 27981_McCain Grocery CATLIN Engineers and Scientists
CATLIN Project No. 223071 9 October 2023
details is presented in AST’s final injection report, included in its entirety in Appendix D.
Following the completion of injection activities, AST collect post-injection
groundwater samples from MW-1R, MW-2 and MW-6 on June 21, 2023. 6.2 GAUGING DATA
Between 2016 and 2021, depth to water has ranged from 29.40 feet below
top of casing (BTOC) (MW-5) to 45.41 feet BTOC (MW-1R). LNAPL has historically been measured in former monitoring well MW-1 and monitoring well MW-6. Groundwater flow direction has been previously illustrated towards the west (Terracon, 2021).

During the June 28, 2023 and July 24, 2023 sampling events, CATLIN personnel measured depth to water in three monitoring wells (MW-1R, MW-2, and MW-6) using an electronic water interface probe. To prevent cross contamination, the probe and cabling were decontaminated according
to manufacturer’s recommendations between use in each well. Gauging data
were recorded on an electronic groundwater sampling form using a tablet device. Gauging procedures were performed in general accordance with North Carolina Department of Environmental and Natural Resources (NCDENR) and NCDEQ Guidelines, and EPA Region 4 Operating
Procedures.
On June 28, 2023, depth to water ranged from 36.45 feet BTOC (MW-2) to 40.33 feet BTOC (MW-1R). Light non-aqueous phase liquid (LNAPL, aka free product) was not encountered during this event. Based on groundwater
elevations calculated for this monitoring period, groundwater flow direction is
towards the west-northwest. On July 24, 2023, depth to water ranged from 36.37 feet BTOC (MW-2) to 40.62 feet BTOC (MW-1R). LNAPL was not encountered during this event.
Based on groundwater elevations calculated for this monitoring period,
groundwater flow direction is towards the west-northwest. Monitoring well gauging results for events conducted by CATLIN are presented in Table 3. Groundwater elevations and flow direction during the
June 28, 2023 and July 24, 2023 sampling events are illustrated on Figures 4
and 5, respectively. Groundwater sampling forms with gauging data are provided in Appendix C. 6.3 SAMPLING DATA

Following gauging, the monitoring wells MW-1R, MW-2, and MW-6 were sampled in general accordance with NCDENR and NCDEQ Guidelines, and EPA Region 4 Operating Procedures. Prior to obtaining representative groundwater samples, each monitoring well was purged by removing a
NCDEQ; 27981_McCain Grocery CATLIN Engineers and Scientists
CATLIN Project No. 223071 10 October 2023
minimum of three well volumes using a new, disposable bailer. Groundwater sampling data were transferred to the electronic groundwater sampling forms. Copies of the field data sheets are available in Appendix C.

After a minimum of three well volumes were removed (or the well was bailed dry), groundwater samples were collected from the wells and poured into appropriate, laboratory-provided, pre-preserved glassware, labeled, and placed on ice in an insulated cooler.

The groundwater samples were submitted to the RPI Project Support Laboratory in Golden, Colorado under proper chain of custody (COC) protocol and analyzed per EPA Method 8260B, EPA Method 300.1, and EPA Method RSK-175. The laboratory analytical data and COC are included in
Appendix E.
6.4 SUMMARY OF GROUNDWATER INFORMATION Historically, samples from monitoring wells MW-1R, MW-2, and MW-6 have
contained the highest petroleum constituent concentrations. During the
previous sampling event conducted by CATLIN (March 2023), samples from MW-1R, MW-2, MW-3, and MW-6 contained VOCs at concentrations above the 2L GWQS. The MW-1R sample also contained benzene and EDB concentrations exceeding their respective GCL. AST conducted pre-injection
sampling for selected wells on June 6, 2023 to determine the baseline levels
of targeted analytes. The current laboratory analytical results are presented in Tables 4 and 5 and the historical results are summarized in Tables 6 and 7. These are discussed in the following sections. Summarized available historical sampling and gauging data from previous consultants are provided
in Appendix A.
VOCs per EPA Method 8260B Prior to the injection event, AST conducted sampling of selected wells
(analyzed by RPI per EPA Method 8260B) on June 6, 2023 and a post injection sampling event on June 21, 2023. Laboratory analytical results reported by RPI during the pre-injection sampling identified many petroleum constituents at concentrations which exceeded their respective 2L GWQS in MW-1R, MW-2, and MW-6. Additionally, benzene was reported at a
concentration which exceeded its GCL in MW-1R. During the June 28, 2023 monitoring event conducted by CATLIN, three monitoring well groundwater samples (MW-1R, MW-2, and MW-6) were collected and submitted to RPI for analysis per EPA Method 8260B.
Laboratory analyses detected multiple petroleum constituents above their respective 2L GWQS in the samples from MW-2 and MW-6. However, no targeted analytes were reported above their respective GCLs. Concentrations in MW-1R were reduced to below laboratory method detection limits.
NCDEQ; 27981_McCain Grocery CATLIN Engineers and Scientists
CATLIN Project No. 223071 11 October 2023
During the July 24, 2023 monitoring event, the same three monitoring well groundwater samples were collected and submitted to RPI for the method detailed above. Laboratory analysis detected the same constituents above
their respective 2L GWQS in the sample from MW-2. Only benzene was
reported above its 2L GWQS in the MW-6 sample. No targeted analytes were reported above their respective GCLs. The latest groundwater sampling laboratory results for EPA Method 8260B
analyses are summarized in Table 4 and the historical laboratory results for
these analyses are summarized in Table 6. Pre-injection monitoring well sample analytical results (June 6, 2023) are illustrated on Figure 6 and post-injection monitoring well sample analytical results (June 28 and July 24, 2023) are illustrated on Figure 7. A summary of RPI data and the individual

for TVPH per Method 8260B. Laboratory analysis of these samples reported detections in each of the samples at concentrations which exceeded their respective reporting limits. During the June 28, 2023 monitoring event, three monitoring well
groundwater samples (MW-1R, MW-2, and MW-6) were collected and submitted to RPI for analysis per 8260B. Laboratory analysis revealed detections of targeted analytes in well MW-2 and MW-6. During the July 24, 2023 monitoring event, the same three monitoring well
groundwater samples were collected and submitted to RPI for the same analysis. Laboratory analysis revealed detections of targeted analytes in MW-2 and MW-6. The latest groundwater sampling laboratory results for the Method 8260B

6.5 EVALUATION OF ASSESSMENT INFORMATION
Extent of Contamination The highest contaminant concentrations have historically been reported in
samples from MW-1R and MW-6. The contaminant concentrations in samples obtained from MW-1R and MW-6 have generally decreased in comparison to those historically reported. Many petroleum constituents were detected above their respective 2L GWQS
NCDEQ; 27981_McCain Grocery CATLIN Engineers and Scientists
CATLIN Project No. 223071 13 October 2023
in samples from wells MW-2 and MW-6 during both sampling events. However, no targeted analytes were reported above GCL. A summary of monitoring well groundwater sample analytical results and the extent of 2L
GWQS for both sampling events are illustrated on Figure 6. The dissolved
phase contaminant plume has not been horizontally or vertically delineated. Review of the baseline sampling event (June 6, 2023) and the 5-weeks post injection sampling event (7/24/2023) revealed the following reductions of
TVPH and benzene concentrations in monitoring wells MW-1R, MW-2 and
MW-6:
Well ID TVPH Reduction (%) Benzene Reduction (%)
MW-1R >99 % >99.9
MW-2 +18.2 % (increase) 26.3
MW-6 97 % 99.7
It should be noted that EDB was detected above the GCL in the MW-1R sample collected in March 2023; however, EDB was not analyzed during the baseline or any of the post injection sampling events.
Cleanup Levels Achieved
Soil – To date, approximately 300 tons of impacted soil have been removed from the site. Soil samples obtained in 2016 indicate that VOC, semi-VOC, and EPH/VPH are above STGW MSCCs. VPH were above their Residential
MSCCs, but below Industrial/Commercial MSCCs (Terracon, 2016).
Groundwater – Groundwater contaminant concentrations are above 2L GWQS but below GCL at the site.
LNAPL – LNAPL was not measured during this monitoring period. LNAPL has not been detected since 2019. 7.0 CONCLUSIONS AND RECOMMENDATIONS

Conclusions Groundwater monitoring findings for this period are summarized below:
• Remedial injections of BOS 200®+ were completed according to the AST bid
package received and approved by NCDEQ.
• Groundwater sample EPA Method 8260B analytical results revealed one or more targeted analytes above their 2L GWQS in samples collected from
monitoring wells MW-2 and MW-6 during both sampling events.
• Groundwater concentrations have decreased to below laboratory method detection limits in MW-1R. In the pre-injection (baseline) sampling event, benzene was above the GCL in the sample collected from source area monitoring well MW-1R.
NCDEQ; 27981_McCain Grocery CATLIN Engineers and Scientists
CATLIN Project No. 223071 14 October 2023
• No targeted analytes were reported at concentrations greater than their respective GCLs during both sampling events.
• Groundwater sample EPA Method RSK-175 analytical results revealed detections of targeted analytes in each of the wells in both sampling events.
• Groundwater sample EPA Method 300.1 analytical results revealed
detections of targeted analytes in each of the wells in both sampling events.
• Groundwater flow direction was calculated to be toward the west-northwest during both monitoring events.
As indicated in Section 6.5, overall TVPH and benzene concentrations have
decreased in MW-1R and MW-6. The 5-weeks post injection sample from MW-2 revealed a slight increase in TVPH concentration and a slight decrease in benzene concentration. As illustrated on Figures 6 and 7, MW-2 is outside the injection areas.
Recommendations
CATLIN recommends continuing with quarterly monitoring and sampling events for the first year following the injection. The next event should be conducted in November 2023. Samples should be sent to a North Carolina certified laboratory to
be analyzed per SM 6200 and also sent to RPI to be analyzed as specified by AST.
8.0 LIMITATIONS
The groundwater samples analyzed as part of this investigation only provide isolated
data points and may not represent conditions at every location in the project area.
Analyses and conclusions of this report, being based on interpolation between data points at the project area, may not be completely representative of all site conditions. Conclusions and recommendations of this investigation and report are based on the best available data in an effort to comply with current regulatory
requirements.

All results in micrograms per liter (µg/L).
BMDL = Below Method Detection Limit (refer to analytical report for a complete list of analytes and detection limits)
VOCs = Volatile Organic Compounds
NA = Not Analyzed
NE = Not Established
GCL = Gross Contaminant Level
2L GWQS = NCAC T15A:02L Groundwater Quality Standards
Bold results indicate concentrations above 2L GWQS.
Shaded results indicate concentrations above GCL.
< = Less than Reporting or Method Detection Limit
* = The value represents the sum of the reported practical quantitation limit of one analyte and the detected concentration of the other analyte.
ƚ = The method detection limit is above the 2L GWQS.
J = Detected but below the Reporting Limit (lowest calibration standard); result is an estimated concentration (CLP J-Flag).
L = Laboratory fortified blank/laboratory control sample recovery and duplicate recovery are outside of control limits. Reported value for this compound is likely to be biased on the low side (L-04 Flag).
** = Sample analyzed via SM 6200B by Pace Analytical Laboratory. All other samples were analyzed via EPA Method 8260B by RPI Group Project Support Laboratory.

RE: BOS 200® Injection Summary Report
Former McCain Grocery
10018 Lancaster Hwy, Waxhaw, NC 28173

Dear Mr. Ashba,

AST Environmental, Inc. (AST) appreciates the opportunity to provide injection services to address
petroleum impacts in soil and groundwater at the 10018 Lancaster Hwy, Waxhaw, NC from June 6th
to June 21st, 2023. AST has prepared the following report to summarize field activities and provided
detailed information on injection locations and loadings, Figure 1 and Table 1, respectively.
Additionally, a photographic log (Attachment A) is included.

The scope was to inject BOS 200+® (BOS) to address petroleum hydrocarbon contamination in the
saturated soil and groundwater. A Kinetic design approach uses traditional BOS 200® Trap & Treat®
processes, with the addition of supplemental nutrients and substrates (starch, magnesium sulfate,
and yeast extract) to create conditions conducive to accelerate the biodegradation rate of the
microbial activity on the activated carbon.

The following are the cleanup goals for the site:

• Mass reduction – Petroleum concentrations below 2Ls

SUMMARY OF FIELD OPERATIONS

On Monday, June 5, 2023, AST mobilized to the site with the Injection Trailer and all associated
tooling for the scope of work. The first day was spent staging the injection system and Geoprobe
3230 track rig and offloading/staging product deliveries. The product was offloaded and staged in
the parking lot of adjacent property (10014 Lancaster Hwy, Waxhaw, NC). Also on June 5, Rain for
Rent delivered a mini-frac tank for onsite water storage. A 55kW generator and track loader were
procured from Herc Rental of Charlotte.

On June 6, the injection system setup continued, the injection grid was laid out, and the three
impacted monitoring wells were purged and sampled. Below is a table including the groundwater
data acquired during the pre-injection sampling process.

MW-6 39.2’ 48’ ~ 5 gal Clear, BTEX odor
MW-2 36.8’ 45’ ~ 4 gal Clear, no odor

Injections began the afternoon of Tuesday, June 6, in Area A. Following the injection of point A-03,
discolored water was visible in water purged from MW-1R, confirming the injection volume planned
for the each interval. Injections in Area A continued through June 8. Early refusal was encountered
at 48’ bgs and 45’ bgs while drilling A-23 and A-25, respectively. Based on the exclusion of some of
these deeper intervals due to limitations of the injection tooling in the underlying lithology, the
decision was made to inject unused product at points that exhibited high levels of contamination.

Area C injections began on June 9 and continued until June 15. As in Area A, AST encountered
early refusal at 5 of the 28 points. Unlike Area A, unused product in Area C was injected in four
additional injection points on the southwest side of the site to provide additional treatment area of
the down gradient dissolved phase plume. While injecting C-12, the water level within MW-6 rose
to, and overtopped the casing of MW-6. On June 15, Area A injections resumed. All injections were
completed on June 20.

On June 21, AST completed site restoration by rough grading, seeding, and laying down straw on
disturbed ground. All impacted monitoring wells were purged and sampled follow injections. While
purging MW-1R and MW-6, it was discovered that a considerable amount of BOS 200 had settled in
the bottom of both wells’ casings. To remove this product, the wells were flushed with fresh water
from a garden hose and purged using a Typhoon pump until there was no discernible product in the
bottom of the casing. AST mobilized off site at 13:00 on June 21, 2023.

The BOS 200® slurries were prepared using AST’s trailer mounted mixing and injection system. AST
utilized a top-down injection technique to ensure effective distribution within the subsurface during
in-situ injection. Injection was performed using a Wanner Engineering Hydracell D35 positive
displacement diaphragm pump system capable of 35-70 gallons per minute (gpm) and up to 1,200
psig. This is critical to ensuring effective distribution of suspended slurries in fine-grained low
permeability sediments and was confirmed by observing water level rise and BOS 200 infiltration
into the monitoring wells.

Injection points within the 7.5 triangular grid were completed at alternating vertical intervals
(compared to the closest adjacent points) to provide both overlap and separation off-sets, but they
were also completed in a staggered sequence of every other point in a row and skipping a row as
work progresses. This process is used to minimize hydraulic loading and allow enough time to
discharge accumulated subsurface pressure in an area from hydraulic injection of fluids. Finally,
allowing injection point back-pressure to stabilize before tooling removal and proper abandonment
of completed injection points following tooling removal prevents daylighting and short-circuiting to
adjacent injection points during subsequent borehole completion.

To mitigate daylighting and its perceived hazards and/or concerns, detailed pressure logs and
continuous monitoring of the immediate surroundings by field personnel is maintained throughout
the injection project. Pressure logs maintained during injections are particularly important as they
can shed light on the type of soil where injection is being completed and whether injectate is simply
bypassing to a previous depth or other preferential path. During injections, instances of moderate to
major daylighting occurred, however, these occasions were infrequent and sporadic. It should be
noted that while injecting A-02, major daylighting occurred around the casing of MW-1R, indicating
a poor seal during well construction. This daylighting ceased at 40’ bgs.

RESULTS AND CONCLUSIONS
Over the course of the injection there were numerous observations of water level rise both visually
and using a water level indicator of 10’ or more from a well. There was one occasion in which water
rose to the top of the casing and out of the well from MW-6. BOS was also found in the purge water
from MW-1R and MW-6 after developing them. These combined visual observations of BOS
slurry/formation water purged from both wells provide good evidence of subsurface distribution of
BOS slurry in the formation.
Site restoration included spreading of grass seed and straw in all areas along with smoothing ruts
caused by the weather and heavy equipment. Groundwater samples were collected from the 3 wells
on site, summarized in the below table. AST demobilized the injection trailer from the site the
afternoon of the same day.
Below are additional recommendations moving forward at this site:
● Continue to monitor VOC, TVPH and anion data post injection. AST recommends continued
post injection groundwater sampling events until remediation goals are obtained. AST
understands that this will be performed by others. The performance samples can be sent to
Remediation Products, Inc. Laboratory in Golden, Colorado for no cost of analyses. The
analyses will be consistent with that described previously. Quarterly monitoring will dictate
if/when additional injection events occur.
● Post injection development and purging of the wells may be necessary to obtain a clear
sample.
AST recommends performing progress groundwater sampling events at intervals of one week post
injection, one-month post-injection and quarterly thereafter. Post injection samples should be sent
to the RPI Laboratory for tracking of VOC, TVPH, anion and dissolved gas concentration trends.
The post injection samples can be submitted to RPI for no-cost analysis.
If you have any questions or wish to discuss the information provided herein, please feel free to

Sincerely,
AST Environmental, Inc.
