On January 15 and 16, 2020, ECS collected a field blank and groundwater samples from monitoring wells MW-1 through MW-5, MW-7 through MW-14, and deep monitoring well DW-1. Monitoring well MW-6 was observed to be dry; therefore, ECS was unable to collect a
groundwater sample. ECS also collected groundwater samples from active water supply wells PW-3R, PW-4B, WSW-2, and WSW-3. During the site reconnaissance, ECS spoke with Mr. Ray Foushee on the phone to inquire about the well construction of water supply well PW-4B. Mr. Foushee informed ECS that well depth and screen length interval is unknown and that Person
County Public Utilities did not have construction records for the well on file. ECS additionally spoke with Mr. Clifton Bradsher, property of water supply well WSW-2 located at 50 Glen Fogleman Road, and according the Mr. Bradsher, his water supply well was installed to an
approximate depth of 50 feet. According to the well I.D. tag for water supply well WSW-3, this water supply well was installed to a depth of 180 ft. bgs and screened from 48 ft. bgs to 180 ft. bgs. ECS was unable to identify a well tag or obtain well construction information on water supply well PW-3R. On October 16, 2020, ECS contracted with KCI Technologies, Inc. (KCI) to
conduct a professional survey to obtain the top of casing elevations for the fifteen (15) monitoring wells.
Laboratory analysis of the groundwater samples collected reported several targeted analytes identified at concentrations exceeding their respective North Carolina 2L Groundwater Quality Standards (NC2LGWQS), with the concentrations of benzene, methyl-tert-butyl ether (MTBE) and 1,2-dibromoethane (EDB) also reported above their respective Gross Contamination Levels
(GCLs). Laboratory analysis of the water supply well samples identified several volatile organic compounds (VOCs) at concentrations above their respective laboratory reporting limits from water supply wells WSW-3, PW-3R, and PW-4B with the detected concentrations of MTBE in PW-3R
and PW-4B exceeding the NC2LGWQS. Laboratory analysis did not report targeted analytes above their respective laboratory reporting limits in the groundwater sample from water supply well WSW-2.
Mr. Matt Gillis of ECS and Mr. Mark Petermann of NCDEQ discussed the possibility of installing a new water supply well to replace PW-3R near the agricultural field located north of the residence located on the subject site. Based on the results and conclusions of this Groundwater Monitoring Report, ECS recommends the following:
• ECS and NCDEQ meet to discuss the hydrogeology at the site to develop approaches for
future environmental assessments. Topics to discuss include, but not limited to, include: developing cross sections, determining information regarding water supply well depths, installation of piezometers, and/or performing additional assessment using a Hydraulic
Profiling Tool (HPT) to estimate fracture locations and densities within the bedrock.
• Further discuss the possibility of installing a replacement water supply well for PW-3R.
• Consider excavation in the area of the anomaly which may indicate the presence of a UST along the southern side of the site building. Consider removal of UST if one is uncovered
• Consider excavation and removal of the concrete pad, product piping, and residual soils where the dispensers were formerly located.
• Consider use of a well camera system or geophysical tools to evaluate construction and
total depths of water supply wells WSW-2, WSW-3, PW-3R, and PW-4B.

1.0 SITE HISTORY
The subject site is known as Mt. Harmony Grocery and is located at 1818 Mt. Harmony Church Road in Rougemont, Person County, North Carolina (Figures 1 and 2). According to information provided to ECS by the North Carolina Department of Environment Quality (NCDEQ), the site formerly operated as a convenience store and gasoline station, known as Little Huff Oil Company. Reportedly, the station operated two 1,000-gallon gasoline USTs, which were removed in March
1990 (Table 1).
In March of 1990, Groundwater Management Associates Inc. (GMA) reportedly conducted soil and groundwater sampling at the site. GMA collected ten soil samples from the walls and floor of the excavation after the removal of the two USTs. Composite soil samples from the walls (S1
through S5) were taken from depths of three to nine feet below ground surface (ft. bgs). Grab soil samples from the bottom of the excavation (S6 through S10) ranged from six to nine ft. bgs. Laboratory analysis reported total petroleum hydrocarbons gasoline range organics (TPH-GRO)
above the current action level of 50 mg/kg in soil samples S1 and S4 through S10. Laboratory analysis also reported TPH-GRO above the laboratory reporting limit but below the action level
of 50 mg/kg in soil samples S2 and S3 (Table 2). Additionally, GMA collected three groundwater samples from water supply wells PW-2 through PW-4. Laboratory analysis reported benzene, toluene, and total xylenes at concentrations above their respective North Carolina 2L Groundwater Quality Standard (NC2LGWQS) but below their respective Gross
Contaminant Level (GCL) in groundwater sample collected from water supply well PW-2. Laboratory analysis reported xylenes above the laboratory reporting limits but below its NC2LGWQS in the groundwater sample collected from PW-3, which reportedly supplied water
to the former store. According to a figure, PW-3 appeared to be located to the south-southwest behind the building on the subject site. Since then, water supply well PW-3 has been replaced by the current active water supply well PW-3R located near the subject sites western property boundary.
In September of 2005, GeoLogix conducted a Phase I and II Limited Site Assessment (LSA). During the Phase I portion of the LSA, Geologix installed a monitoring well (MW-UST) within the
former location of the USTs. Soil samples were collected at depths of eleven and twenty-one ft. bgs. Laboratory analysis reported benzene and methyl-tert butyl ether (MTBE) at concentrations above their respective GCLs in the groundwater sample collected from MW-UST. Based on the results of the Phase I LSA, Geologix determined a Phase II LSA was
required. During the Phase II LSA, one deep/vertical extent well (DW-1) and three shallow monitoring wells (MW-1 through MW-3), were constructed. Geologix collected groundwater samples from monitoring well DW-1 and MW-1 through MW-3. Laboratory analysis reported
MTBE at a concentration above its NC2LGWQS but below its GCL in the groundwater sample collected from monitoring well DW-1. Laboratory analysis reported benzene above its GCL in the groundwater sample collected from monitoring well MW-1 through MW-3. Laboratory analysis reported several additional analytes above their respective NC2LGWQSs but below
their respective GCLs in the groundwater sample collected from monitoring wells MW-1 through MW-3. Based on the levels of benzene and MTBE in the groundwater from monitoring wells MW-1 through MW-3, Geologix stated it appears the highest level of petroleum contamination is directed to the southeast and may be an indicator of groundwater flow.
Geologix identified three water supply wells adjacent to the subject site. Geologix stated laboratory analysis of the water supply well (PW-2) located on the Latta property (adjacent to
Groundwater Monitoring Report – Mt. Harmony Grocery Rougemont, Person County, North Carolina
NCDEQ Incident No. TF-3831 NCDEQ Contract No. N17006 ECS Project No. 49:3051-F

the south) reported several targeted analytes in the groundwater sample. Additionally, xylenes were reported in the currently inactive water supply well (PW-3) located to the south-southwest of the subject site, replaced by the current active water supply well PW-3R located near the
western property boundary of the subject site. Little Huff Oil Company agreed to construct a new potable water supply well for the Latta residence located south of the subject site (WSW-3). Reportedly, a new well, replacing its predecessor, was also constructed for the residence located on the subject property north of the source area (PW-1). Water from that well was also
shared by the grocery store. Geologix stated a Comprehensive Site Assessment (CSA) may be required.
On October 10, 2016, ECS collected groundwater samples from monitoring wells MW-1 through MW-4 and DW-1. The resident at the subject site (1818 Mt. Harmony Church Road) was not present at the time of sampling and ECS did not observe an exterior spigot on the house; therefore, ECS did not sample water supply well PW-1. ECS observed water supply well
structures presumably containing PW-2 and PW-4. ECS did not receive written permission to collect groundwater samples from these wells. Additionally, ECS performed a receptor survey and identified eleven potable water supply wells located within 1,000 feet of the subject site.
ECS contacted the City of Roxboro Public Services to inquire if municipal water is available for the subject site and surrounding area. According to the City of Roxboro Public Services, municipal water is not connected to the subject site and is not available to the surrounding area. Laboratory analysis from the October 2016 sampling event reported benzene at a concentration
above its GCL in the groundwater sample collected from monitoring well MW-2. Additionally, laboratory analysis reported benzene and MTBE at concentrations above their respective GCLs in the groundwater sample collected from monitoring well MW-3. Laboratory analysis reported
methyl butyl ketone at a concentration above its NC2LGWQS but below its GCL in the groundwater sample collected from monitoring well DW-1. On August 10, 2017, ECS collected a field blank and groundwater samples from monitoring wells
MW-UST, MW-1 through MW-3, DW-1, and water supply well WSW-3. However, for the sake of consistency, ECS will hereby refer to the monitoring well previously named MW-UST as MW-1; MW-1 as MW-2; MW-2 as MW-3; and MW-3 as MW-4 after observing monitoring well identification tags observed during site reconnaissance and a review of the previous September 2005 Phase I & II Limited Site Assessment (LSA). Quantex, Inc. (Quantex) installed monitoring wells MW-5 and MW-6 on the adjacent property occupied by Mt. Tirzah Park. ECS also collected soil samples for risk-based analysis along the sidewalls of the former UST location and dispenser
island to determine the extent of contaminated soils on the subject site. Petroleum hydrocarbons were detected in one of the soil samples collected adjacent to the former pump island at concentrations above the Soil-to-Groundwater MSCCs (Table 2). On August 11, 2017, ECS collected groundwater samples from water supply well PW-4A (Ball
Park) (formerly identified as WSW-4) and PW-4B (Fire Department) (formerly identified as PW-4). Based on conversations with the NCDEQ and Mr. Ray Foushee of Person County, it was determined that the Mt. Tirzah Park and the Mt. Moriah Fire Department share water supply well PW-4B and water supply well PW- 4A are not active. ECS collected a groundwater sample from
monitoring well MW-5 and attempted to sample monitoring well MW-6 but it was dry at the time. Also, ECS spoke with the tenant of the single-family residence associated with the subject site. She informed ECS that the water supply well (PW-1) is inactive. She indicated that she is not
connected to municipal water and does not currently have water supplied to her home. Before site departure, ECS horizontally and vertically located the two newly installed monitoring wells,

relative to the existing well network and common site benchmark. On August 21, 2017, ECS returned to the site and collected a groundwater sample from
monitoring well MW-6. On August 24, 2017, ECS collected an additional groundwater sample from water supply well PW-4A. On September 26, 2017, the North Carolina Division of Waste Management (DWM) issued a
Health Risk Evaluation regarding the groundwater samples collected at the Mt. Moriah Volunteer Fire Department and Mt. Tirzah Park on August 11, 2017. In this document, DWM stated:
“This water is not recommended for any residential use at this time. This water should pose no significant health risk for its current use, which is to flush toilets and for hand washing at a ball field.”
Based on the results and conclusions of the October 2017 groundwater monitoring report, ECS noted that the contaminant plume had not been delineated to the west, east, south or vertically.
On November 21, 2017, ECS collected a field blank and a groundwater sample from water supply well WSW-2 after obtaining a signed water supply well permission letter. The laboratory did not report targeted analytes at concentrations above the laboratory reporting limits in the groundwater sample collected from water supply well WSW-2 or the field blank.
On January 5, 2018, ECS collected a field blank and groundwater samples from monitoring wells MW-1 through MW-4, and DW-1. ECS attempted to collect groundwater samples from
monitoring wells MW-5 and MW-6; however, these wells were dry at the time. ECS deployed O-Sox in monitoring wells MW-1, MW-3, and MW-4. On January 5, 2018, Quantex, on behalf of ECS, installed one Type II groundwater monitoring well (MW-7) northwest of the former store at the subject site.
On January 8, 2018, ECS collected a groundwater sample from water supply well PW-3R after the tenant identified the location of the well house in the northwestern portion of the subject site. She informed ECS that water supply well PW-3R supplies potable water to the single family residence associated with the subject site. ECS collected a groundwater sample from monitoring well MW-7 after development and purging. Quantex installed Type II groundwater monitoring wells MW-8 through MW-10 on the adjacent Mt. Tirzah Park property. Laboratory
analysis reported multiple NC2LGWQS and/or GCL violations. On September 13, 2018, KCI Technologies, Inc. (KCI) conducted a geophysical survey at the site utilizing ground penetrating radar (GPR) to investigate the soil disturbances and an earthen depression previously documented in the rear of the former store. The GPR survey indicated a negative anomaly that appeared to be a mass of buried metal such as a UST located besides the building.
On September 18-19, 2018, ECS contracted with Quantex, to install two Type II groundwater monitoring wells: MW-11 and MW-12. Monitoring well MW-11 was installed west of monitoring well MW-3 beside the single-family residence. Monitoring well MW-12 was installed north of
monitoring well MW-7 and the former store at the subject site. ECS also collected field blank and a groundwater sample from active water supply wells PW-3R, PW-4B, WSW-2, and WSW-3 and monitoring wells MW-1 through MW-10, and DW-1.

NCDEQ Incident No. TF-3831 NCDEQ Contract No. N17006 ECS Project No. 49:3051-F

On October 1, 2018, ECS deployed O-Sox in monitoring wells DW-1, MW-1, MW-3, MW-4, MW-5, and MW-7 and collected groundwater samples from newly installed monitoring wells MW-11 and MW-12. ECS horizontally and vertically located the two newly installed monitoring
wells (MW-11 and MW-12), relative to the existing well network and common site benchmark. Based on the results and conclusions of the September and October 2018 field activities presented in the February 2019 Groundwater Monitoring Report prepared for the NCDEQ,
ECS recommended contacting Mr. Billy Barber, Mrs. Kristi Williams (Latta), and Mrs. Bobbie Latta to request permission to install two off-site monitoring wells on the southern properties owned by the aforementioned parties. ECS recommended installing two additional monitoring
wells on the adjoining, southern Latta/Williams properties, sample, and horizontally and vertically locate the two proposed monitoring wells, relative to the existing well network and common site benchmark. ECS recommended collecting a soil sample from down-gradient of the anomaly identified during the GPR assessment. ECS recommended installing Enviro-Bac or
similar devices in monitoring wells MW-1, MW-3, MW-4, MW-7 and MW-11 and then resampling monitoring wells DW-1, MW-1 through MW-12 within 60 days to determine efficacy. ECS recommended collecting groundwater samples from water supply wells WSW-2, PW-3R,
WSW-3 and PW-4B and attempt to obtain permission for a second time to collect groundwater samples from water supply wells WSW-5, WSW-6, WSW-7, and WSW-8. On April 17-18, 2019, ECS collected a field blank and groundwater samples from monitoring
wells MW-1 through MW-12, and DW-1. ECS also collected groundwater samples from active water supply wells PW-3R, PW-4B, WSW-2, and WSW-3. On May 3, 2019, ECS contracted with Quantex to advance two soil borings to collect one soil sample from each boring at depths
ranging from 5 to 10 ft. bgs for risk-based analysis. The borings were located downgradient of the negative anomaly from a geophysical survey conducted in September 2018. The anomaly was suspected to be a UST, located adjacent to the building, in an effort to determine if there is potential soil contamination related to the anomaly on the subject site. Historical soil sample
analytical results are included in Table 2. Quantex also installed two Type II groundwater
monitoring wells: MW-13 and MW-14. Monitoring well MW-13 was installed near the northeast
corner of Latta property and monitoring well MW-14 was installed near the southeast corner of the Latta property. Following installation, on May 3, 2019 ECS collected groundwater samples from the two newly installed monitoring wells (MW-13 and MW-14). On May 9, 2019, ECS
horizontally and vertically located the two newly installed monitoring wells (MW-13 and MW-14), relative to the existing well network and common site benchmark. Based on the results and conclusions of the April and May 2019 field activities presented in the
June 21, 2019 Comprehensive Site Assessment and a discussion with Mr. Mark Petermann of NCDEQ, ECS recommended:
• ECS and NCDEQ meet to discuss the hydrogeology at the site to develop approaches for future environmental assessments. Topics to discuss include, but not limited to, include: developing cross sections, determining information regarding water supply well depths,
installation of piezometers, and/or performing additional assessment using a Hydraulic Profiling Tool (HPT) to estimate fracture locations and densities within the bedrock.
• Consider excavation in the area of the anomaly which may indicate the presence of a UST along the southern side of the site building. Consider removal of UST if one is uncovered
• Consider excavation and removal of the concrete pad, product piping, and residual soils
where the dispensers were formerly located.
Groundwater Monitoring Report – Mt. Harmony Grocery Rougemont, Person County, North Carolina
NCDEQ Incident No. TF-3831 NCDEQ Contract No. N17006 ECS Project No. 49:3051-F

• Consider use of a well camera system or geophysical tools to evaluate construction and total depths of water supply wells WSW-2, WSW-3, PW-3R, and PW-4B.

2.0 SITE GEOLOGY AND HYDROGEOLOGY
As determined from the USGS Topographic Maps, Moriah and Timberlake, North Carolina Quadrangles dated 2016 (Figure 1), the site is at an approximate elevation of 655 feet above mean sea level. According to the topographic map, the site is located on the northwestern edge of a topographic high point. Surface runoff from the site appears to flow radially from the site.
The subject site is situated in the Piedmont Physiographic Province. The soils encountered in this area are the residual product of in-place chemical weathering of rock presently underlying the site and/or historic depositional events. In general, shallow unconfined groundwater
movement within the overlying soils is controlled largely by topographic gradients. However, as the groundwater percolates downward, it becomes controlled by the subsurface geologic conditions. Thus, the direction of groundwater movement in the deeper aquifers may not be
consistent with the reflecting topography. The elevation of the shallow water table is transient and can vary with seasonal fluctuations in precipitation. 3.0 RECEPTOR INFORMATION 3.1 Water Supply Wells On October 10, 2016, ECS performed a walking and vehicular reconnaissance of properties
within 1,000 feet of the site. Water supply wells were observed at residences along Mt. Harmony Church Road within 1,000 feet of the site. ECS contacted the City of Roxboro Public Services and according to municipal records, municipal water supply wells are not located within 1,000 feet of the subject site. Water supply well questionnaires were mailed via United
States Postal Service (USPS) to the property owners located within 500 feet of the source area. On September 26, 2016, ECS received a completed water supply well questionnaire from Mr.
Billy Barber (1818 Mt. Harmony Church Road; subject site) stating the property contains an active water supply well (PW-1) and is not connected to municipal water. On September 29, 2016, ECS received a completed water supply well questionnaire from Mr. Pete Thomas (1655 Mt. Harmony Church Road; Mount Harmony Baptist Church) stating that the property contains
an active water supply well (WSW-1) that supplies drinking water to 250 people. Water supply well WSW-1 is located 745 feet to the north-northeast. On December 13, 2016, ECS received a completed water supply well questionnaire from Mr. Ray Foushee, the General Services Director of the Person County Government, associated with the Mt. Tirzah Ball Park. He indicated that the Concessions Stand near the baseball diamond has an active water supply well (PW-4A (formerly identified as WSW-4)) that supplies drinking water and restroom fixtures to the public.
During the field activities conducted on August 10 and 11, 2017, ECS received a completed water supply well questionnaire from Mrs. Kristi Latta (1850 Mt. Harmony Church Road; adjoining southern residence) stating the property contains one active, potable water supply well (WSW-3) that supplies water to her home. Mrs. Kristi Latta informed ECS that water supply well PW-2 is inactive but the pump house dispenses water from water supply well WSW-3. ECS received Ms. Bobbie Latta’s (131 Peed Road; adjoining vacant agricultural land) permission to
sample water supply well WSW-3 on August 10, 2017. Additionally, ECS spoke with the tenant
Groundwater Monitoring Report – Mt. Harmony Grocery Rougemont, Person County, North Carolina
NCDEQ Incident No. TF-3831 NCDEQ Contract No. N17006 ECS Project No. 49:3051-F

of the single-family residence associated with the subject site. She informed ECS that the water supply well (PW-1) is inactive. She indicated that she is not connected to municipal water and does not currently have water supplied to her home.
On August 24, 2017, ECS spoke with Mr. Foushee on the phone and learned that the Mt. Tirzah Ball Park and the Mt. Moriah Volunteer Fire Department property share active water supply well (PW-4B) (formerly identified as PW-4) and that water supply well PW-4A (Ballpark)
is not active. He indicated that the Fire Department uses their water supply well for cleaning, special events, restroom fixtures, and fundraising cook-outs. He noted that they do not fill their fire-trucks with groundwater from the water supply well.
On November 21, 2017, ECS collected a groundwater sample from active, potable water supply well WSW-2 (Bradsher Well) after obtaining a signed water supply well permission letter.
On January 8, 2018, ECS collected a groundwater sample from water supply well PW-3R after the tenant identified the location of the well house in the northwestern portion of the subject site. She informed ECS that water supply well PW-3R supplies potable water to the single
family residence associated with the subject site where she resides. On September 18, 2018, ECS collected a groundwater sample from active water supply wells PW-3R, PW-4B, WSW-2, and WSW-3. ECS was informed by the current tenants of 1850 Mt.
Harmony Church Road that the former tenants had moved but the property owner, Ms. Bobbie Latta, arrived on-site to grant ECS permission to sample the active, potable water supply well WSW-3, which is located on her property.
On January 16, 2020, ECS spoke with Mr. Foushee on the phone to inquire about the well construction of water supply well PW-4B. Mr. Foushee informed ECS that well depth and screen length interval is unknown and that Person County Public Utilities did not have construction
records for the well on file. ECS additionally spoke with Mr. Clifton Bradsher, property of water supply well WSW-2 located at 50 Glen Fogleman Road, and according the Mr. Bradsher, his water supply well was installed to an approximate depth of 50 feet. According to the well I.D. tag for water supply well WSW-3, ECS noted the water supply well was installed to a depth of 180 ft. bgs and screened from 48 ft. bgs to 180 ft. bgs. ECS was unable to identify a well tag or obtain well construction information regarding water supply well PW-3R.
Mr. Matt Gillis of ECS and Mr. Mark Petermann of NCDEQ discussed the possibility of installing a new water supply well to replace PW-3R near the agricultural field located north of the residence located on the subject site. The names and addresses of the property owners with water supply wells located within 1,000
feet of the site are included in Table 3 and shown on Figure 3. The names and addresses of the
adjacent property owners are included in Table 4 and shown on Figure 4.

3.2 Public Water Supplies On November 6, 2018, ECS contacted the City of Roxboro Public Services and was told that municipal water is not connected to the subject site and not available to the surrounding area. The closest waterline that could be run to the area is reportedly located approximately 3.5 miles to the south of the subject site along Helena-Moriah Road.

4.0 FIELD ACTIVITIES

4.1 Monitoring Well Sampling and Surveying Activities

On January 15 and 16, 2020, ECS collected a field blank and groundwater samples from monitoring wells MW-1 through MW-5 and MW-7 through MW-14 and DW-1. Monitoring well MW-6 was observed to be dry; therefore, ECS was unable to collect a groundwater sample.
The locations of the monitoring wells are shown on Figure 5. Purging and sampling of monitoring wells were accomplished using a disposable bailer. Site photographs documenting
field activities are included in Appendix A.

On January 15, 2020, ECS contracted with KCI to conduct a professional survey of the top of casing elevations for the fifteen (15) monitoring wells (MW-1 through MW-14 and deep monitoring well DW-1). The survey data collected provided by KCI is included in Appendix B. Prior to the sampling activities, ECS measured the depth to groundwater in each of the monitoring wells using a decontaminated water level meter and used this data to calculate
groundwater flow direction. A summary of the monitoring well construction data and
groundwater elevations are included on Table 5. Groundwater flow was determined to generally
flow outward in an approximate radial pattern away from subject site as shown on Figure 3.
Prior to beginning groundwater sampling activities, ECS collected a field blank by pouring DI water over the water level meter probe and into the laboratory prepared sample containers. Purging and sampling of the monitoring wells were accomplished using a peristaltic pump and
dedicated tubing, respectively. ECS collected geochemical measurements at each well for each well volume purged using a YSI-556 multi-parameter meter. Geochemical measurements are shown in Table 6. Groundwater Monitoring Well Sampling Data sheets and ECS personnel field
notes are provided in Appendix C.

4.2 Water Supply Well Sampling Activities On January 16, 2020, ECS collected groundwater samples from active water supply wells PW-3R, PW-4B, WSW-2, and WSW-3. The water supply wells were purged by discharging water
from the wells for approximately 10-15 minutes. After purging was completed, the sampler wearing a new pair of disposable nitrile gloves for each sampling point collected a sample from the exterior spigot on the well. Immediately after collection, the groundwater samples were
transferred into sample containers provided by the laboratory. 4.3 Sample Preparation The sample containers were labeled with ECS project number, sample identification, sample
date and time, and requested analytical analysis. The containers were placed into protective packaging material and placed into a cooler with ice to maintain the samples at approximately
4° Celsius (°C). The samples were submitted to Con-Test Analytical Laboratory in East
Longmeadow, Massachusetts for chemical analysis for Volatile Organic Compounds (VOCs) using Standard Method 6200B. ECS maintained proper chain of custody (COC) procedures throughout the sample collection and transportation process. The laboratory analytical data and the COC are included in Appendix D.

5.0 LABORATORY ANALYTICAL RESULTS

5.1 Monitoring Well Sampling Analytical Results
Laboratory analysis reported benzene and EDB at concentrations above their GCLs of 5,000 µg/L and 50 µg/L, respectively, in the groundwater sample collected from monitoring wells MW-5 and MW-11. Laboratory analysis reported MTBE at concentrations above its GCL of 20,000 µg/L in the groundwater sample collected from monitoring wells MW-4 and DW-1. Laboratory analysis reported several targeted analytes above their respective NC2LGWQS but
below their respective GCL in the groundwater samples collected from monitoring wells MW-1, MW-3, MW-4, MW-5, MW-7, MW-8, MW-11, MW-12, and MW-13 and deep monitoring well DW-1. Laboratory analysis reported several additional targeted analytes above their respective laboratory reporting limits but below their respective NC2LGWQS in the groundwater samples
collected from monitoring wells MW-1 through MW-5, MW-7, MW-8, MW-11, MW-12, and MW-13 and deep monitoring well DW-1.
Acetone was detected in the field blank and the groundwater sample collected from monitoring well MW-10 above its laboratory reporting limit; however, the detections were at concentrations that were not in exceedance of its reporting limit (lowest calibration standard). It should be noted that acetone is a common laboratory artifact, and based on the historical groundwater
analytical results, the reported estimated detections may not be indicative of acetone being present in groundwater at the site. ECS considers this detection to be possible laboratory contamination and unrepresentative of site conditions or sampling procedures.
Laboratory analysis did not report targeted analytes above their respective laboratory reporting limits in the field blank or the groundwater samples collected from monitoring wells MW-9 and MW-14.
5.2 Water Supply Well Sampling Analytical Results Laboratory analysis of the water supply well samples identified select VOCs at concentrations above their respective laboratory reporting limits from water supply wells WSW-3, PW-3R, and
PW-4B with the detected concentrations of MTBE in PW-3R and PW-4B exceeding the NC2LGWQS. Laboratory analysis did not report targeted analytes above their respective laboratory reporting limits in the groundwater sample from water supply well WSW-2.
A summary of the current groundwater laboratory analytical results, including water supply well
results, are included in Table 7 and on Figures 7 and 8. Isoconcentration maps depicting the
horizontal extent of benzene, EDB, and MTBE are shown on Figures 9 through 11. A summary
of the historical groundwater laboratory analytical results are included in Table 8. The laboratory
analytical data sheets and COCs are included in Appendix D. 7.0 CONCLUSIONS
Based on the results of this Groundwater Monitoring Report, ECS has the following conclusions:
• A release from the two USTs has impacted the groundwater with several targeted analytes
Groundwater Monitoring Report – Mt. Harmony Grocery Rougemont, Person County, North Carolina
NCDEQ Incident No. TF-3831 NCDEQ Contract No. N17006 ECS Project No. 49:3051-F
identified at concentrations exceeding their respective NC2LGWQS, with the concentrations of benzene, MTBE, and EDB also reported above their respective GCLs.
•Based on the groundwater elevation data, the groundwater is inferred to flow outward fromthe site in a radial pattern.
•There are nine active water supply wells identified within 1,000 feet of the release. Three ofthe active water supply wells, WSW-3, PW-3R, and PW-4B, are located within 500 feet of
the release.
•According to the City of Roxboro Public Services, municipal water is not connected to the
subject site and not available to the surrounding area. Additionally, according to Mr.Foushee, it is unknown as to the depth and screen interval of water supply well PW-4B withno construction record on file.
•During the site reconnaissance, ECS observed the water supply well WSW-3 was installed toa depth of 180 ft. bgs and screened from 48 to 180 ft. bgs according its well tag. ECS
additionally spoke with Mr. Bradsher, property of water supply well WSW-2 located at 50 GlenFogleman Road, and according the Mr. Bradsher, ECS was informed that his water supplywell was installed to an approximate depth of 50 feet. ECS was unable to identify a well tag or
obtain any well construction information regarding water supply well PW-3R.
•The extent of the contaminant plume has not been delineated to the west and north of the
site.
8.0 RECOMMENDATIONS
Based on the results and conclusions of this Groundwater Monitoring Report, ECS
recommends the following:
•ECS and NCDEQ meet to discuss the hydrogeology at the site to develop approaches forfuture environmental assessments. Topics to discuss include, but not limited to, include:developing cross sections, determining information regarding water supply well depths,installation of piezometers, and/or performing additional assessment using a HydraulicProfiling Tool (HPT) to estimate fracture locations and densities within the bedrock.
•Further discuss the possibility of installing a replacement water supply well for PW-3R.
•Consider excavation in the area of the anomaly which may indicate the presence of a USTalong the southern side of the site building. Consider removal of UST if one is uncovered.
•Consider excavation and removal of the concrete pad, product piping, and residual soilswhere the dispensers were formerly located.
•Consider use of a well camera system or geophysical tools to evaluate construction andtotal depths of water supply wells WSW-2, WSW-3, PW-3R, and PW-4B.

*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
Reported result is estimated. Value reported over verified calibration range.E
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
pH of sample (pH 3) is outside of method specified preservation criteria.PR-06
pH of sample (pH 4) is outside of method specified preservation criteria.PR-07
pH of sample (pH 6) is outside of method specified preservation criteria.PR-09
pH of sample (pH 7) is outside of method specified preservation criteria.PR-10
Elevated reporting limit due to high concentration of target compounds.RL-11
