2.0 EXECUTIVE SUMMARY
The Willis Grocery, Inc. (aka T&P Quick Stop) site is located at 4025 NC Highway
10, Newton, Catawba County, North Carolina. Five underground storage tanks
(USTs) were previously operated at the site. One 550-gallon gasoline, one 500-gallon kerosene, and three 1,000-gallon gasoline USTs were removed from the site in 1999. A petroleum release was discovered while taking tank inventory in 1985.

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 July 10 through 22, 2023 and AST injected a total of 30,850 pounds of BOS200+ into 54
injection points. CATLIN Engineers and Scientists (CATLIN) personnel met the AST
team on site on July 11, 2023 to observe the initial day of the injection activities. On August 7, 2023, CATLIN personnel returned to the site for the first of two post-injection sampling events. During the August 7, 2023 site activities (2-weeks post-
injection), CATLIN measured groundwater at an average of approximately 23.7 feet
depth feet deep across the site. Light non-aqueous phase liquid (LNAPL; aka free-phase product) was measured at 0.5 feet thick in MW-6 and 0.01 feet thick in MW-7A. Approximately 0.5 gallons of LNAPL was bailed and placed into the on-site drum. Groundwater samples from six monitoring wells (MW-2, PMW-4, PMW-5,
MW-6, MW-7A, and MW-8A) were collected. The samples were submitted to Con-
Test Analytical Laboratory (Con-Test) for laboratory analysis of volatile organic compounds (VOCs) per Standard Method (SM) 6200B plus ethylene dibromide (EDB), methyl tert-butyl ether (MTBE) and diisopropyl ether (DIPE). Additionally, samples from the same wells were submitted to Remediation Products, Inc.
Laboratory (RPI) for laboratory analysis of 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 August 21, 2023, CATLIN personnel returned to the site for the second of two
post-injection sampling events. During the August 21, 2023 site activities (4-weeks post-injection), CATLIN measured groundwater at an average of approximately 23.8 feet depth feet deep across the site. LNAPL was measured at 1.0 feet thick in MW-6 and 0.05 feet thick in MW-7A. Approximately 0.7 gallons of LNAPL was bailed and placed into the on-site drum. Groundwater samples from the same six monitoring
wells were collected. After sampling activities were completed, a sorbent sock was placed in MW-6 to assist with collection of LNAPL. The samples were again submitted to both Con-Test and 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, MW-6, MW-7A, and MW-8A 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 2-weeks and 4-weeks post-injection samples. Additionally, benzene and/or MTBE were detected at concentrations which
NCDEQ; 20091_Willis Grocery.doc CATLIN Engineers and Scientists
CATLIN Project No. 223094 3 October 2023
exceeded their respective Gross Contaminant Levels (GCLs) in wells MW-6, MW-7A, and MW-8A in both the 2-weeks and 4-weeks post-injection samples.
Trends were not obvious across the VOC analyses (SM 6200B versus Method
8260B) for either the 2-weeks or 4-weeks post-injection samples. The laboratory analytical results from the Method RSK-175 and the Method 300.1 analyses appeared to show a slight downward trend. For the wells where baseline sampling was conducted on July 10, 2021, TVPH constituent concentrations have decreased
by 78.7% (MW-6), 73.7% (MW-7A), and 50% (MW-8A) as of the 4-weeks post-
injection period. The TVPH concentrations in MW-2 did not experience any significant change. Benzene concentrations (as analyzed per EPA Method 8260B) decreased by 29.7% (MW-6), 52.4% (MW-7A) and 51.5% (MW-8A). It should be noted that during the baseline sampling event samples were not analyzed per SM
6200B and the August 21, 2023 results per SM 6200B were generally higher than
the EPA Method 8260B analysis from the same sampling event. CATLIN recommends to:
• Continue with quarterly monitoring and sampling events for the first year
following the injection. The next event should be conducted in November 2023;
• Conduct monthly LNAPL removal from MW-6, MW-7A and MW-8A with the
use of a submersible pump; and
• Replace and maintain sorbent socks in MW-6, MW-7A, and MW-8A to passively collect LNAPL.

The presence of the suspected UST identified during the private utility location at the site was investigated using a backhoe to remove the surface soil. Upon excavation to approximately five feet deep, the anomaly was found to be a 12-inch diameter corrugated metal pipe. This pipe was found to be truncated on both ends and no
fluid was present inside. Soils were replaced into the excavation and compacted
using the equipment. The remaining scope of services was conducted in general accordance with the approved TAs. 4.0 SITE HISTORY AND CHARACTERIZATION

The Willis Grocery site is located at 4025 NC Highway 10, Newton, Catawba County, North Carolina (Figures 1 and 2). Summarized available historical sampling and gauging data from previous consultants are provided in Appendix A. Recent site photographs are presented in Appendix B.
4.1 UST OWNER AND OPERATOR INFORMATION Robert Foxx owned the five USTs historically operated on-site. Fuel was supplied by Superior Petroleum & Fuel Co., Inc. The tanks were operated by
Terry Welch for petroleum retail sales. The site was accepted into the North Carolina UST Section Trust Fund Branch State Lead Program in 2004 (NCDEQ, 2017). Available information regarding UST owners and operators is presented in
Table 1.
NCDEQ; 20091_Willis Grocery.doc CATLIN Engineers and Scientists
CATLIN Project No. 223094 5 October 2023
4.2 UST INFORMATION Three 1,000-gallon gasoline, one 550-gallon gasoline, and one 500-gallon
kerosene USTs were previously operated on-site. The 1,000-gallon tanks
were installed in 1985 and the 550 and 500-gallon tanks were installed in 1964. The tanks were removed from the site in January 1999 (Terracon, 2020).
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 July 1985 when a loss of inventory (370
gallons of gasoline) was reported to the North Carolina Department of Environment and Natural Resources (NCDENR, now NCDEQ) Division of Waste Management (DWM). In July 1985, a NCDEQ representative collected a groundwater sample from an on-site hand-dug well. Analytical results
indicated multiple petroleum constituents were present in the well above the
2L standards. In January 1999, the five on-site USTs were closed by removal. Petroleum impacted soils were encountered beneath the 500-gallon kerosene UST and an adjacent 1,000-gallon gasoline UST. Approximately 20 cubic yards of petroleum-impacted soil were removed from the tank pit.
Confirmation soil samples indicated petroleum-impacted soils remained in
the tank excavation. 4.4 SITE CHARACTERISTICS
The property was formerly owned by Salvador and Cynthia Hernandez and
the property is occupied by a retail business (Crossroads Pet Supplies). On October 9, 2023, the property was purchased by Ms. Diana Najera Perez. The parcel is comprised of the store building, paved parking area, and grass groundcover. 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 a mix of residences, commercial
warehouses, forest, and agricultural land. The site is bound by NC Highway
10 to the north and Hickory Lincolnton Highway to the southwest. A residence adjoins the site to the south and the parcel to the east is undeveloped.
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; 20091_Willis Grocery.doc CATLIN Engineers and Scientists
CATLIN Project No. 223094 6 October 2023
the Willis Grocery site was conducted in 2017 by Terracon Consultants, Inc. (Terracon).
According to previous reports, municipal water is available to the site vicinity,
although not all properties are connected. Based on the 2017 receptor survey the following were identified:
• Fourteen water supply wells within 1,500 feet of the site.
• An active non-potable well (SW-3) located at an adjacent property south of the site.
• Eight active (assumed potable) wells located within 1,000 feet from
the site.
• One well of unknown status (SW-9) located 470 feet north of the site.
• An unnamed tributary of the South Fork Catawba River, a Class
Water Supply Well-5 (WS-V) surface water body located 365 feet
southeast from the site. 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 As discussed above, an on-site release was discovered in July 1985 when a loss of inventory (370 gallons) was reported to the NCDENR, DWM. In July
1985, a NCDEQ representative collected a groundwater sample from an on-site hand-dug well. Analytical results indicated multiple petroleum constituents were present in the well above the 2L standards. As a result, two monitoring wells (MW-1 and MW-2) were installed downgradient of the UST system and two wells (MW-3 and MW-4) were installed upgradient and cross
gradient of the tank basin, respectively. Petroleum constituents were detected in the downgradient wells (Terracon, 2020). In January 1999, the five on-site USTs were closed by removal. Petroleum impacted soils were encountered beneath the 500-gallon kerosene UST and
an adjacent 1,000-gallon gasoline UST. Approximately 20 cubic yards of petroleum-impacted soil were removed from the tank pit. Confirmation soil samples indicated petroleum-impacted soils remained in the tank excavation (Terracon, 2020).
Beginning in 1999, S&ME conducted a series of on-site activities. Seventeen water supply wells were identified within 1,000 feet of the source area. Three additional wells were installed (PMW-3, PMW-4, and PMW-5). A July 2000 monitoring event revealed various petroleum constituents above their respective 2L standards in wells MW-1, MW-2, and PMW-5. Additionally,
benzene was also detected in wells MW-1 and MW-2 above its GCL. The direction of groundwater was estimated to be toward the southeast. The next sampling event was conducted in 2009 (MW-3 and MW-4 could not be located and were presumed destroyed). Three nearby water supply wells were sampled but no targeted analytes were detected. Additionally, the
NCDEQ; 20091_Willis Grocery.doc CATLIN Engineers and Scientists
CATLIN Project No. 223094 7 October 2023
receptor survey was updated which indicated that SW-1, SW-2, SW-3, SW-6 and SW-7 had been connected to municipal water supplies. S&ME conducted an aggressive fluid and vapor recovery (AFVR) event in February
2010 during which a total of 1,053 gallons of fluid were removed from the
wells and approximately 15 gallons of gasoline as vapor were recovered. Samples collected from MW-1 and MW-2 after the AFVR event contained petroleum constituents above 2L GWQS and benzene above its GCL in well MW-2. Two additional groundwater sampling events were conducted by
S&ME in 2011 and 2012, indicating that petroleum constituents remained
above their 2L GWQS and benzene remained above its GCL (Terracon, 2020). In 2013, Crawford Environmental Services (CES) installed well MW-6 near
the former tank excavation and collected a soil sample from the boring for the
well at a depth of approximately 20 feet below ground surface (BGS). The analytical results of the soil sample detected petroleum constituents above the Soil to Groundwater (STGW) Maximum Soil Contaminant Concentration (MSCC). Analytical results of the groundwater sample from well MW-6
detected benzene above its GCL and various other target analytes above
their respective 2L standards (Terracon, 2022). Between October 2017 and November 2022, Terracon conducted a receptor survey update and a series of various groundwater activities. Groundwater
concentrations at the site have remained above the 2L standards, and
LNAPL has consistently been encountered in MW-6. At various times, Terracon deployed/replaced absorbent socks in well MW-6. Terracon conducted mobile multi-phase extraction (MMPE) events in January and July of 2019, removing a total of 9,122 gallons of water/product mixture and VOC
emissions of approximately 101.4 gallons. Sampling event results indicated
that the concentrations in the wells were not significantly reduced. In June 2021, Terracon supervised the completion of a Remedial Design Characterization event at the site. AST advanced soil borings, collected groundwater samples, and performed slug testing on wells MW-2 and MW-6.
Analysis and modeling of the soil sample analytical results indicated that
approximately 40,265 pounds of TVPH remained at the site. Air sparge (AS) and soil vapor extraction (SVE) test wells (AS-1 and SVE-1, respectively) were installed, and groundwater sampling was conducted in July 2022. In August 2022, the AS/SVE pilot test was conducted using the newly installed
wells, and indoor air sampling was performed. The AS/SVE pilot test data
indicated that the radius of influence was 10 feet or less. Terracon concluded that a system could be designed for the site using closely spaced wells. Additionally, while elevated VOCs were not identified in the on-site building, there was concern about that potential if the AS/SVE system was in
operation for a long period of time. Because of this, a vapor intrusion
mitigation system (VIMS) Terracon suggested that should be considered for the building if the AS/SVE system is implemented (Terracon, 2022).

Summarized available historical sampling and gauging data from previous consultants are provided in Appendix A.
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 an amphibolite and biotite gneiss formation within the Inner Piedmont Belt. According to the 1985 Geologic Map of North Carolina,
interlayered metagabbro, mica schist, and granitic rock crop out in the site
area. Boring logs provided by S&ME, Inc. (2000) indicate that mainly clayey-sandy-silt is present to approximately 35 feet BGS with a narrow band of silty
coarse sand from approximately 11-13 feet BGS (S&ME, 2000).
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.

Surface Water – One surface water body was identified within 1,500 feet of the site. An unnamed tributary of the South Fork Catawba River is located
approximately 365 feet southeast of the site. According to the NCDEQ North
Carolina Surface Water Classifications GIS viewer the South Fork Catawba River is identified as a Class WS-V surface water body. 6.0 SITE ASSESSMENT INFORMATION
CATLIN conducted all field activities in general accordance with the approved TAs and pre-prepared, site-specific Health and Safety Plan (HASP). Upon each arrival at the site, potential hazards were evaluated before beginning field work. Electronic Job Hazard Analysis (JHA) forms and 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 July 10 and 22, 2023. CATLIN personnel were on site on July 11, 2023 to observe the beginning of the injection process.
After the remediation injection had been completed, CATLIN personnel returned to the site to gauge and collect groundwater samples from monitoring wells MW-2, MW-6, MW-7A, MW-8A, PMW-4, and PMW-5 at 2-weeks and 4-weeks post-injection. The samples were sent to two different laboratories for different analyses;
NCDEQ; 20091_Willis Grocery.doc CATLIN Engineers and Scientists
CATLIN Project No. 223094 9 October 2023
one set of samples was sent to Con-Test for analysis of VOCs per SM 6200B plus DIPE, EDB, and MTBE, and the second set was sent to RPI laboratory 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 1,750 square feet with 31 points) and Area B (approximately 1,270 square feet with 23 points), were set up with a grid spacing of
approximately 7.5 feet and a vertical injection interval of 18 to 36 feet BGS. 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 July 10 through July 22, 2023 to complete the activities. Complete information concerning the equipment used, products included in the remedial mixture, injection point spacing, injection pressure, rate of pumping, and additional process details is presented in AST’s final injection report, included in its entirety in Appendix
D. 6.2 GAUGING DATA Historically, depth to water has ranged from 15.50 feet below top of casing
(BTOC) (PMW-5) to 32.72 feet BTOC (PMW-3). LNAPL has historically been measured in monitoring wells MW-6. Groundwater flow direction has been previously illustrated towards the east-southeast (Terracon, 2022). During the August 7 and 21, 2023 gauging and sampling events, CATLIN
personnel measured depth to water in six monitoring wells 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 NCDENR and NCDEQ Guidelines, and EPA Region 4 Operating Procedures. On August 7, 2023, the depth to water ranged from 18.87 feet BTOC (PMW-5) to 30.45 feet BTOC (MW-6). LNAPL (0.5 feet thick and 0.01 feet
thick) was measured in monitoring wells MW-6 and MW-7A, respectively. The depths to water measured in PMW-5 was above its screened interval. Based on groundwater elevations calculated for this monitoring period, groundwater flow direction is towards the southeast.
NCDEQ; 20091_Willis Grocery.doc CATLIN Engineers and Scientists
CATLIN Project No. 223094 10 October 2023
On August 21, 2023, the depth to water ranged from 19.44 feet BTOC (PMW-5) to 25.72 feet BTOC (MW-6). LNAPL (1.0 feet thick and 0.05 feet thick) was measured in monitoring wells MW-6 and MW-7A, respectively.
The depths to water measured in PMW-5 was above its screened interval.
Based on groundwater elevations calculated for this monitoring period, groundwater flow direction is towards the south-southeast. Monitoring well gauging results for both August 2023 events are presented in
Table 3. Groundwater elevations and flow directions for the August 7 and
August 21, 2023 events are illustrated on Figure 4 and Figure 5, respectively. Field data sheets with gauging data are provided in Appendix C. 6.3 SAMPLING DATA

Following gauging, the monitoring wells were sampled by CATLIN 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 minimum of three
well volumes using a new, disposable bailer. Groundwater sampling data
was 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 directly into appropriate, laboratory-provided, pre-preserved glassware, labeled, and placed on ice in an insulated cooler. A laboratory-provided trip blank from Con-Test was maintained in the Con-Test cooler for the duration of each of the events.
One set of groundwater samples and a laboratory-provided trip blank for each of the two events were submitted to Con-Test Analytical Laboratory (Certification NC 652 and NC-DW 25703) in East Longmeadow, Massachusetts, under proper chain of custody (COC) protocol and analyzed
per SM 6200B (including EDB, MTBE, and DIPE). One set of groundwater samples for each of the two events were submitted to RPI laboratory in Golden, Colorado under proper COC protocol and analyzed per EPA Method 8260B (for VOCs and TVPH), EPA Method 300.1,
and EPA Method RSK-175. 6.4 SUMMARY OF GROUNDWATER INFORMATION Historically, samples from monitoring wells MW-2, MW-6, MW-7A, and
MW-8A have contained the highest petroleum constituent concentrations. During the previous sampling event conducted by Terracon (2022), samples from MW-7A and MW-8A contained multiple VOCs at concentrations above the 2L GWQS as well as benzene and MTBE above GCL. AST conducted pre-injection sampling for selected wells on various dates to determine the

baseline levels of targeted analytes. These are discussed in the following sections. Summarized available historical sampling and gauging data from previous consultants are provided in Appendix A.

Monitoring Wells VOCs per SM 6200B and Method 8260B
Prior to the injection event, AST conducted sampling of selected wells
(analyzed by RPI per Method 8260B) on various dates to determine the baseline levels of the targeted analytes. Laboratory analytical results reported by RPI identified many petroleum constituents at concentrations which exceeded their respective 2L GWQS in MW-2, MW-6, MW-7A, and
MW-8A. Additionally, benzene and naphthalene were reported at
concentrations which exceeded their respective GCLs in MW-6; benzene and MTBE were reported at concentrations which exceeded their respective GCLs in MW-7A; and benzene was reported at a concentration which exceeded its GCL in MW-8A.

During the August 7, 2023 monitoring event, six monitoring well groundwater samples (MW-2, MW-6, MW-7A, MW-8A, PMW-4, and PMW-5) were collected and submitted to Con-Test for analysis per SM 6200B (including EDB, MTBE, and DIPE) and also to RPI for analysis per Method 8260B.
Laboratory analyses detected many petroleum constituents above their
respective 2L GWQS in the samples from MW-2, MW-6, MW-7A, and MW-8A. Benzene and MTBE concentrations were detected above their respective GCLs in MW-8A, and benzene was detected above its GCL in MW-6 and MW-7A.
During the August 21, 2023 monitoring event, the same six monitoring well groundwater samples were collected and submitted to Con-Test and to RPI for the methods detailed above. Laboratory analysis detected many constituents above their respective 2L GWQS in the samples from MW-2,
MW-6, MW-7A, and MW-8A. Benzene and MTBE concentrations were detected above their respective GCLs in MW-7A and MW-8A, and benzene was detected above its GCL in MW-6. The latest groundwater sampling laboratory results for SM 6200B and
Method 8260B analyses are summarized in Table 4 and the historical
laboratory results for these analyses are summarized in Table 6. Monitoring well sample analytical results for both sampling events conducted (August 7 and August 21, 2023) are illustrated on Figure 6. A copy of the complete laboratory reports and COC documentation from Con-Test and a laboratory-
provided summary of RPI data and the individual COCs are included in Appendix E.

EPA Method 8260B (TVPH) Pre-injection samples from wells MW-2, MW-6, MW-7A, and MW-8A were
analyzed 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 August 7, 2023 monitoring event, six monitoring well groundwater
samples (MW-2, MW-6, MW-7A, MW-8A, PMW-4, and PMW-5) were
collected and submitted to RPI for analysis per 8260B. Laboratory analysis revealed detections of targeted analytes in wells MW-2, MW-6, and MW-8A. During the August 21, 2023 monitoring event, the same six monitoring well
groundwater samples were collected and submitted to RPI for the same
analysis. Laboratory analysis revealed detections of targeted analytes in MW-2. The latest groundwater sampling laboratory results for the Method 8260B
analysis for TVPH are summarized in Table 5 and the historical laboratory
results for this analysis are summarized in Table 7. A summary of RPI data and the individual COCs are included in Appendix E. EPA Method RSK-175
Pre-injection samples from wells MW-2, MW-6, MW-7A, and MW-8A were analyzed per Method RSK-175. Laboratory analysis of these samples reported detections in each of the samples at concentrations which exceeded their respective reporting limits.

EPA Method 300.1 Pre-injection samples from wells MW-2, MW-6, MW-7A, and MW-8A were
analyzed per Method 300.1. Laboratory analysis of these samples reported
detections in each of the samples at concentrations which exceeded their respective reporting limits. During the August 7, 2023 monitoring event, six monitoring well groundwater
samples (MW-2, MW-6, MW-7A, MW-8A, PMW-4, and PMW-5) were
collected and submitted to RPI for analysis per Method 300.1. Laboratory analysis revealed detections of targeted analytes in each of the wells at concentrations which exceeded their respective reporting limits.
During the August 21, 2023 monitoring event, the same six monitoring well
groundwater samples were collected and submitted to RPI for the same analysis. Laboratory analysis revealed detections of targeted analytes in each of the wells at concentrations which exceeded their respective reporting limits.

The latest groundwater sampling laboratory results for the Method 300.1 analysis are summarized in Table 5 and the historical laboratory results for this analysis are summarized in Table 7. A summary of RPI data and the individual COCs are included in Appendix E.

Trip Blanks One laboratory-provided trip blank sample was submitted to Con-Test for each of the two sampling events on August 7 and 21, 2023 for analysis per
SM 6200B (including EDB, MTBE, and DIPE). No targeted analytes were
detected in either of the samples. The two packages of laboratory analytical data and COCs from Con-Test for both sampling events are included in Appendix E.
6.5 EVALUATION OF ASSESSMENT INFORMATION Extent of Contamination
The highest dissolved phase concentration BTEX compounds has historically
been reported in samples from monitoring wells MW-2, MW-6, MW-7A, and MW-8A. Many petroleum constituents were detected above their respective 2L GWQS
in samples from wells MW-2, MW-6, MW-7A, and MW-8A during both
sampling events. Benzene and MTBE were reported above their respective GCLs in MW-7A and MW-8A during both sampling events, and benzene was reported above its GCL in MW-6 during both sampling events. A summary of monitoring well groundwater sample analytical results and the extent of 2L
NCDEQ; 20091_Willis Grocery.doc CATLIN Engineers and Scientists
CATLIN Project No. 223094 14 October 2023
GWQS and GCL exceedances for both sampling events are illustrated on Figure 6. The dissolved phase contaminant plume has not been horizontally or vertically delineated.

For the wells where baseline sampling was conducted on July 10, 2021, TVPH constituent concentrations have decreased by 78.7% (MW-6), 73.7% (MW-7A), and 50% (MW-8A) as of the 4-weeks post-injection period. The TVPH concentrations in MW-2 did not experience any significant change.
Benzene concentrations (as analyzed per EPA Method 8260B) decreased by
29.7% (MW-6), 52.4% (MW-7A) and 51.5% (MW-8A). It should be noted that during the baseline sampling event samples were not analyzed per SM 6200B and the August 21, 2023 results per SM 6200B were generally higher than the EPA Method 8260B analysis from the same sampling event.

Cleanup Levels Achieved
Soil – To date, approximately 20 cubic yards of impacted soil have been removed from the site. Soil samples obtained in 1999 indicated that
confirmation soil samples detected that petroleum-impacted soils still
remained in the tank basin (Terracon, 2020).
Groundwater – Groundwater contaminant concentrations remain above 2L GWQS, and benzene and MTBE are above their respective GCLs at the site.

LNAPL – LNAPL was measured at 0.5 feet thick in MW-6 and 0.01 feet thick in MW-7A during the August 7, 2023 sampling event and was also measured at 1.0 feet thick in MW-6 and 0.05 feet thick in MW-7A during the August 21, 2023 event. LNAPL has been periodically measured at the site since at least
2013.
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 SM 6200B and Method 8260B analytical results revealed multiple targeted analytes above their 2L GWQS in samples collected from monitoring wells MW-2, MW-6, MW-7A, and MW-8A during both sampling events.
• Groundwater sample SM 6200B and Method 8260B analytical results revealed both benzene and/or MTBE at concentrations greater than their respective GCLs in the samples collected from MW-6, MW-7A, and MW-8A during both sampling events.
• Groundwater sample Method RSK-175 analytical results revealed detections of targeted analytes in each of the wells except PMW-5 in both sampling events, and also PMW-4 on August 21, 2023.
NCDEQ; 20091_Willis Grocery.doc CATLIN Engineers and Scientists
CATLIN Project No. 223094 15 October 2023
• Groundwater sample 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 southeast during the August 7, 2023 sampling event and toward the south-southeast during the August 21, 2023 sampling event.
Recommendations
CATLIN recommends to:
• Continue with quarterly monitoring and sampling events for the first year
following the injection. The next event should be conducted in November 2023;
• Conduct monthly LNAPL removal from MW-6, MW-7A and MW-8A with the use of a submersible pump; and
• Replace and maintain sorbent socks in MW-6, MW-7A, and MW-8A to passively collect LNAPL. 8.0 LIMITATIONS

RE: BOS 200+® Injection
Willis Grocery
4025 NC Highway 10
Newton, NC – Catawba County

Dear Ms. Ghiold,

AST Environmental, Inc. (AST) appreciates the opportunity to provide injection services at the above-
referenced site. This letter summarizes the BOS 200®+ (BOS) injection activities conducted from July 10th,
2023, through July 22nd, 2023. The original scope as proposed is outlined below:

Proposed Injections:

Injection Area Surface Area # of Points Grid Spacing Vertical Interval BOS 200®+ (lbs.)
Area A ~1,750 ft2 31 7.5’ 18’-36’ 34,115 lbs
Area B ~1,270 ft2 23 7.5’ 18’-36’ 25,360 lbs

SUMMARY OF FIELD ACTIVITIES

On July 10th, 2023, AST personnel mobilized with injection equipment and reagents to the site. AST set up
the injection system, marked the injection point on a 7.5’ triangular grid, and gauged/redeveloped/purged
monitoring wells MW-6, MW-7, and MW-8 using a typhoon pump. Groundwater samples were then
collected using bailers. The samples were submitted for laboratory analysis at RPI Group Project Support
Laboratory in Golden, CO. Pre-injection groundwater samples submitted to RPI will be analyzed for VOCs
using EPA Method 8260b, Anions using EPA Method 300.1 Ion Chromatography, and Dissolved Gases
using EPA Method RSK-175. The attached Figure depicts a layout of the injection points and other
pertinent features; photographs documenting injection activities are included in Attachment A.

The BOS 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 the injection
effort. Injections were performed using a positive displacement pump of up to 35-70 gallons per minute

(gpm) at 1,200 psi. The flow rate was set at 35 gpm for the initial injection points, then increased to 45
gpm. Based on the observations of the water response and pressures observed, the speed increased to
60 gpm for the entire project to optimize the fluid velocity at the injection tip during BOS installation. This
is critical to effectively distributing suspended slurries in coarse-grained soil. Two-and-a-Quarter Inch
(2.25”) diameter direct-push rods were advanced to the target intervals using a track-mounted Geoprobe®
3230DT drilling unit; BOS slurries were delivered through an injection tip with six (6) 5/32” diameter ports
oriented 60° apart on the horizontal plane.

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.

Table 1 details and summarizes the injection metrics recorded during remedial injections. This table
includes the following:

1. The injection point location identification (e.g., A01)
2. The time each injection occurred.
3. The pressure metrics used to support induced fracture emplacement have occurred.
4. The quantity of BOS and supplements injected at each interval, the total amount per day, the total
amount per area, and the total for the project.
5. The vertical interval of each injection in feet below ground surface (bgs)
6. Any comments or observations by staff while performing the remedial injections.

It is important to note that the “Injection Pressure” column in Table 1 represents the sum of the internal
system pressure plus formational pressure. The internal system pressure includes all losses due to fittings,
hoses, valves, and drill tooling. A close approximation of the actual pressure seen at the injection tip outlet
can be determined by subtracting the system pressure losses from the recorded value observed at the
discharge end of the pump. The system losses are approximately 180 psi and then 220 psi for the
components used during this injection event. This calculation has been included under a separate column
titled “Formation Pressure.”

injections points (514 vertical intervals). Once each injection point was completed and the tooling string
removed from the ground, the borehole was plugged with hydrated bentonite and capped with matching
surface conditions.

Injection Observations:
 July 19th, 2023 - injecting on A23, groundwater overflowed MW-6 casing on intervals 33’ & 35’ bgs

 July 20th, 2023 - injecting on A29 at intervals 31’, 33’, and 35’ bgs, groundwater overflowed MW-
6 casing.

 July 12th, 2023 - injecting on A20, 2’ groundwater rise observed in MW-8 casing on intervals 30’,
32’ & 33’ bgs

 July 19th, 2023 - injecting on B29 at intervals 29’, 31’, and 33’ bgs, groundwater overflowed MW-
6 casing.

After injections, existing monitoring wells MW-8, MW-7, and MW-6 were redeveloped and purged using
a downhole pump. Groundwater samples were collected on July 22nd, 2023, using a peristaltic pump and
bailers. The samples were submitted for laboratory analysis at RPI Group Project Support Laboratory in
Golden, CO. Post-injection groundwater samples submitted to RPI will be analyzed for VOCs using EPA
Method 8260b, Anions using EPA Method 300.1 Ion Chromatography, and Dissolved Gases using EPA
Method RSK-175. The laboratory analytical results for the pre- and post-injection groundwater samples
were unavailable in this report and will be submitted under separate cover letter transmittal.

CONCLUSIONS AND RECOMMENDATIONS

Adequate distribution was observed throughout the injection event; instances of distribution include (but
are not limited to) a hydraulic response and visual identification of BOS in monitoring wells,
surfacing/daylighting at a distance from the point of injection, or the presence of a sheen, free product,
or hydrocarbon odor during the injection.

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 others will perform this. The performance samples can be sent to Remediation Products, Inc.
Laboratory in Golden, Colorado, for no analysis cost. The analyses will be consistent with those
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 transparent
sample.

AST recommends performing progress groundwater sampling events at intervals of one-week post-
injection, one-month post-injection, and quarterly after that. Post-injection samples should be sent to
the RPI Laboratory to track 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, please call me at [phone] or

CASE NARRATIVE SUMMARY
All reported results are within defined laboratory quality control objectives unless listed below or otherwise qualified in this report.
For method 6200B elevated reporting limits for samples 23H1410-01,04,05+06 due to high concentrations of target compounds.
[TOC_1]Case Narrative[TOC]
SM21-23 6200B
Qualifications:
Laboratory fortified blank/laboratory control sample recovery and duplicate recoveries outside of control limits. Data validation is not
affected since all results are "not detected" for associated samples in this batch and bias is on the high side.
Analyte & Samples(s) Qualified:
L-02
Bromomethane
B348788-BS1, B348788-BSD1
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.
Analyte & Samples(s) Qualified:
L-04

*QC result is outside of established limits.
Wide recovery limits established for difficult compound.
Wide RPD limits established for difficult compound.
#Data exceeded client recommended or regulatory level
Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
No results have been blank subtracted unless specified in the case narrative section.
FLAG/QUALIFIER SUMMARY
Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
J
Laboratory fortified blank/laboratory control sample recovery and duplicate recoveries outside of control limits.
Data validation is not affected since all results are "not detected" for associated samples in this batch and bias is
on the high side.
L-02
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
Either laboratory fortified blank/laboratory control sample or duplicate recovery is outside of control limits, but
the other is within limits. RPD between the two LFB/LCS results is within method specified criteria.
L-07
Elevated reporting limit due to high concentration of target compounds.RL-11
