2.0 EXECUTIVE SUMMARY
The M&R Grocery site (aka M&R Grocery) is located at 7995 NC Highway 43,
Rocky Mount, Edgecombe County, North Carolina. Four underground storage tanks
(USTs) were previously operated at the site. Two 550-gallon and one 1,000-gallon gasoline USTs were reportedly closed by removal in 1987. Additionally, one 500-gallon UST was reportedly closed by removal in December of 1991. Two 10,000-gallon aboveground storage tanks (ASTs) are currently operating on site. The
release was discovered in 1990 during sampling of the on-site water supply well.
The purpose of this report is to document the latest groundwater sampling event. On May 2, 2023, CATLIN Engineers and Scientists (CATLIN) personnel measured depth to water at approximately 4.4 feet deep across the site. Groundwater samples
were collected from seven monitoring wells and submitted 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). Laboratory results did not indicate any dissolved petroleum constituents above their
respective laboratory reporting limits in the sample from MW-6R. Several VOCs
were detected in the MW-1, MW-4, MW-5, and MW-7R samples at concentrations greater than those established in Title 15A of the North Carolina Administrative Code, Subchapter 2L, Section .0202 Groundwater Quality Standards (2L GWQS), but below the Gross Contaminant Levels (GCL). Only benzene was above its 2L
GWQS in the sample from MW-8R.
Benzene, toluene, ethylbenzene, and total xylenes (BTEX) compound concentrations appear to have increased in the sample from monitoring well MW-5 since the previous sampling event conducted by CATLIN in September 2022.
However, BTEX concentrations have decreased in the samples from monitoring
wells MW-1 and MW-7R. The concentrations in MW-3, MW-4, and MW-8R have fluctuated since the previous event (CATLIN, 2021). CATLIN recommends to:
• Continue to make attempts to get permission to abandon the two inactive water supply wells within 250 feet of the subject site; and
• Conduct an annual groundwater sampling event in May 2024.
3.0 SCOPE OF SERVICES The scope of services for this report was performed in general accordance with CATLIN proposal number 221043.03P, dated April 19, 2023. Services were
authorized by the North Carolina Department of Environmental Quality (NCDEQ) Task Authorization (TA) #03, accepted on April 19, 2023, and Contract Number N122019D.
NCDEQ; 5720_M&R Grocery.doc CATLIN Engineers and Scientists
CATLIN Project No. 221043 3 June 2023
The approved scope of services for this Task Authorization included to:
• Collect groundwater samples from seven monitoring wells (MW-1, MW-3,
MW-4, MW-5, MW-6R, MW-7R, and MW-8R);
• Analyze nine water samples (seven monitoring well samples, one equipment rinsate blank, and one trip blank) per SM 6200B (including EDB, MTBE, and DIPE); and,
• Prepare and submit a monitoring report summarizing the findings.
The scope of services was conducted in accordance with the approved TA.
4.0 SITE HISTORY AND CHARACTERIZATION
M&R Grocery is located at 7995 NC Highway 43, Rocky Mount, Edgecombe County, North Carolina (Figures 1 and 2). Summarized available historical sampling and gauging data from previous consultants are provided in Appendix A. Site
photographs are presented in Appendix B.
4.1 UST/AST OWNER AND OPERATOR INFORMATION One UST was owned and operated by Mr. Ronald Van Rogers from an
unknown date to 1966. Beginning in 1966, Lee Oil Company (now dissolved)
owned and operated three USTs until 1987. The site was accepted into the North Carolina UST Section Trust Fund Branch State Lead Program following the dissolution of Lee Oil Company. The current property owner (Mr. Karim) operates two ASTs on the property.
Available information regarding UST and AST owners/operators is presented in Table 1. 4.2 UST/AST INFORMATION
Reportedly, one orphan 500-gallon petroleum steel UST was operated on-site until 1966. This UST was removed in December 1991. Lee Oil Company operated two 550-gallon gasoline steel USTs between 1966 and 1987, and one 1,000-gallon gasoline steel UST between 1981 and 1987. These USTs
were removed in 1987 (S&ME, 2019; NCDEQ UST Tanks Database). Currently, two 10,000-gallon gasoline ASTs are on-site and used for petroleum retail purposes (S&ME, 2019).
Available UST and AST system information is presented in Table 1 and the approximate former UST basin and the current AST locations are illustrated on Figure 3.

CATLIN Project No. 221043 4 June 2023
4.3 CONTAMINANT SOURCE INVENTORY In March 1990, Edgecombe County Health Department sampled the on-site
water supply well and laboratory results revealed petroleum constituents in
the groundwater (Bryson, 1996). In addition, a soil sample collected on June 5, 1990 (in the former UST system vicinity) revealed a total xylenes concentration above the Soil-to-Groundwater (STGW) Maximum Soil Contaminant Concentration (MSCC) (S&ME, 2019).

In July 1990, during Comprehensive Site Assessment (CSA) activities, Underground Tank Testing Services, Inc. (UTTS) collected eight additional soil samples between one and six feet below land surface (BLS). The samples were located across the site and noted on a map provided by UTTS.
Total petroleum hydrocarbons (TPH) gasoline range organics (GRO) were
detected in each sample, but below the State Action Levels (S&ME, 2019) (UTTS, Site Map of M&R Grocery). The volume of product released from the UST system is unknown. Available
historical information from previous consultants is provided in Appendix A.
4.4 SITE CHARACTERISTICS The property is owned by Mr. Noor Karim and operates as Midway Grocery
(a convenience mart and petroleum retailer). The parcel is comprised of the
store building, two 10,000-gallon gasoline ASTs, and a fuel dispenser island. The ground surface is a combination of an asphalt parking lot in the front of the building with the remainder of the parcel being either grassy or landscaped areas with trees.

The site structures, ASTs, dispenser island, and former UST locations are illustrated on Figure 3. Site photographs are included in Appendix B. 4.5 OWNERS AND OCCUPANTS OF ADJOINING/NEARBY PROPERTIES
AND LAND USE Properties in the site vicinity are mostly residences and undeveloped land. The property to the east of the site is a residential property. The site is bound by an undeveloped wooded parcel to the west and south, and by NC
Highway 43 to the north. 4.6 RECEPTOR INFORMATION CATLIN conducted the most recent receptor survey in May 2021. Pertinent
receptor information is summarized below. Based on correspondence with the Edgecombe County Water and Sewer Department on June 16, 2021, municipal water is available to the subject site and surrounding area. Three water supply wells have been identified within
NCDEQ; 5720_M&R Grocery.doc CATLIN Engineers and Scientists
CATLIN Project No. 221043 5 June 2023
1,500 feet of the site. Within 250 feet of the site, two inactive wells were identified. One active non-potable well is located approximately 590 feet from the site.

One surface water body is located within 1,500 feet of the site. An unclassified pond is located 1,060 feet northwest from the site. Potential receptors are illustrated on Figure 2 and receptor information
obtained from CATLIN (2021) is shown in Table 2.
4.7 PREVIOUS INVESTIGATIONS AND REMEDIAL ACTIVITIES As discussed above, the release was discovered in 1990 after sampling the
on-site water supply well. Two 550-gallon gasoline steel USTs and one
1,000-gallon gasoline steel UST were removed in 1987 (S&ME, 2019). On June 5, 1990, one soil sample was collected near the UST system. Analytical results revealed a total xylene concentration above its STGW
MSCC. In July 1990, during CSA activities, UTTS collected eight additional
soil samples between one and six feet BLS. TPH GRO concentrations were present in each soil sample; however, the concentrations were below the State Action Levels (S&ME, 2019).
Between December 1990 and May 1991, eight groundwater monitoring wells
(MW-1 through MW-8) were installed on the site. Three additional “temporary hand driven” wells were later installed (and sampled) across NC 43 north of the site, results indicated VOC impacts to the groundwater. (Bryson, 1996). In 1991, an orphan UST was discovered and removed by Environmental
Technical Services, Inc. (ETS). Monitoring well MW-2 was abandoned in
November 2007. Replacement wells MW-6R, MW-7R, and MW-8R were installed on November 28, 2012 (S&ME, 2019). Groundwater sampling events have been conducted at this site since 1991
and petroleum constituents above 2L GWQS have consistently been present in MW-1, MW-3, MW-4, MW-5, MW-7/7R, and MW-8R. CATLIN conducted a groundwater sampling event in September 2022. Three temporary monitoring wells (TMW-01, TMW-02, and TMW-03) were installed
to 15 feet BLS; TMW-01 was installed near the former 500-gallon UST basin, TMW-02 was near the edge of NC Highway 43, and TMW-03 was to the north across NC Highway 43. Groundwater samples were collected from the temporary monitoring wells and seven permanent monitoring wells (MW-1, MW-3, MW-4, MW-5, MW-6R, MW-7R, and MW-8R). Several petroleum
constituent concentrations were detected above 2L GWQS in the samples from MW-1, MW-4, MW-5, MW-7R, MW-8R, and TMW-03; however, none were above GCL (CATLIN, 2022).

Summarized available historical data from previous consultants is presented 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 Coastal Plain physiographic province. The site is underlain by the Yorktown formation, and consists of fossiliferous clay, fine-grained sand, and bluish gray shell material (Rhodes et al., 1985).
Soils at the site are comprised mainly of Wagram loamy sand (0-6 percent
slope), which is well-drained and grades from loamy sand to sandy clay loam and sandy loam with depth. Based on limited boring logs prepared by others, soils encountered during
the installation of the monitor wells consisted of clays and fill material (S&ME,
2019). During boring advancement by CATLIN for temporary well construction in September 2022, silty fine sands were encountered near the surface to
approximately six feet deep and were underlain by a highly plastic clay to
roughly 14 feet deep. Borings were terminated at 16 feet BLS in a clayey coarse sand / sandy clay. 5.2 HYDROGEOLOGY

Groundwater - The 2020 Visual Hydrogeologic Framework – North Carolina Hydrogeological Database identified three boreholes near the site. The closest borehole is C.A. Powell, J 28S (A), which is located approximately 1,140 feet west-southwest of the site. This borehole shows the surficial
aquifer extending approximately 15 feet BLS. This is underlain by an approximately 60-foot-thick confining unit (CU), the Upper Cape Fear Aquifer (~60 feet), the Upper Cape Fear CU (~60 feet), and then the Lower Cape Fear Aquifer (~40 feet).
Depth to water at the site has ranged from approximately two to 15 feet BLS.

Surface Water – One pond is located approximately 1,060 feet northwest from the source area.
6.0 SITE ASSESSMENT INFORMATION CATLIN conducted field activities on May 2, 2023, in accordance with the approved TA and pre-prepared Health and Safety Plan (HASP). Upon arrival at the site, potential hazards were evaluated before beginning field work and are documented
NCDEQ; 5720_M&R Grocery.doc CATLIN Engineers and Scientists
CATLIN Project No. 221043 7 June 2023
on an electronic Job Hazard Analysis (JHA) form. The JHA form is included in Appendix C. Photographs from the site visit are included in Appendix B.
CATLIN personnel collected groundwater samples from seven monitoring wells
(MW-1, MW-3, MW-4, MW-5, MW-6R, MW-7R, and MW-8R) and they were submitted for laboratory analysis of VOCs per SM 6200B plus, MTBE, DIPE, and EDB. Well locations and site features are shown on Figure 3 and well construction details are presented in Table 3.
6.1 GAUGING DATA Historically, depth to groundwater in the monitoring wells has ranged from 1.21 below top of casing (BTOC) (MW-7) to 13.05 feet BTOC (MW-3). During
the previous monitoring period, groundwater flow direction was illustrated to
be towards the west-northwest (CATLIN, 2022). Depth to water was measured using an electronic water interface probe. To prevent cross contamination, the probe and cabling were decontaminated
according to the manufacturer’s recommendations between use in each well.
Gauging data were recorded on electronic groundwater sampling forms using a tablet device. Gauging procedures were performed in general accordance with North Carolina Department of Environment and Natural Resources (NCDENR) and NCDEQ Guidelines, and Environmental Protection Agency
(EPA) Region 4 Operating Procedures.
Depth to water ranged from 2.76 feet BTOC (MW-7R) to 6.67 feet BTOC (MW-4). The depths to water measured in all the gauged wells were above their respective screened intervals. Water depths were an average of seven
feet shallower than during the previous monitoring event. Based on
groundwater elevations calculated for this monitoring period, there appears to be localized higher groundwater elevations in the vicinity of both MW-5 and MW-8R, with a general overall groundwater flow towards the east-southeast.
Monitoring well gauging results for events conducted by CATLIN are
presented in Table 3. Groundwater elevations and flow direction are illustrated on Figure 4. 6.2 SAMPLING DATA

Following gauging, the monitoring wells 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 minimum of three well volumes
using a new, disposable bailer. Monitoring well groundwater field parameter
data were measured at one-minute intervals using an In-Situ Aqua TROLL 600 Multiparameter Sonde (Aqua TROLL). Conductivity, pH, oxidation reduction potential (ORP), dissolved oxygen, and temperature measurements were recorded utilizing the VuSitu mobile application (version
NCDEQ; 5720_M&R Grocery.doc CATLIN Engineers and Scientists
CATLIN Project No. 221043 8 June 2023
1.17.12). Groundwater parameter data were transferred from the VuSitu mobile application to the electronic groundwater sampling forms. Monitoring wells MW-3 and MW-5 were bailed dry. Copies of the groundwater sampling
forms are available in Appendix C.
After a minimum of three well volumes were removed (or the well was bailed dry), a groundwater sample was collected from each well and poured into appropriate, laboratory-provided, pre-preserved glassware, labeled, and
placed on ice in an insulated cooler. A laboratory-provided trip blank was
maintained in the cooler for the duration of the sampling event. To verify that sampling equipment was decontaminated sufficiently between wells, an equipment rinsate blank sample was collected from the electronic
water level indicator. Clean distilled water was allowed to cascade down the
electronic indicator wand and into appropriate, laboratory-provided, pre-preserved glassware. The glassware was labeled and placed on ice in an insulated cooler.
The groundwater samples, equipment rinse blank, and laboratory-provided
trip blank 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). The laboratory analytical data and COC are
included in Appendix D.
6.3 SUMMARY OF GROUNDWATER INFORMATION Historically, samples from monitoring wells MW-1, MW-5, and MW-7R have
contained the highest petroleum constituent concentrations, although
monitoring wells MW-3, MW-4, and MW-8R have also exhibited petroleum concentrations which exceeded their respective 2L GWQS. Light non-aqueous phase liquid (LNAPL; aka free phase product) was detected in MW-1 during the 1996 and 2004 sampling events at this site. During the
previous sampling event conducted by CATLIN (September 2022), samples
from MW-1, MW-4, MW-5, MW-7R, and MW-8R contained several targeted analyte concentrations above their respective 2L GWQS. No petroleum constituents have been detected at concentrations above GCL. Portions of historical information prepared by other consultants are included in
Appendix A.
The latest groundwater sampling laboratory results for SM 6200B analysis are summarized in Table 4. Historical results for events conducted by CATLIN are in Table 5. Monitoring well sample analytical results are
illustrated on Figure 5. A copy of the complete laboratory report and COC
documentation are in Appendix D.
NCDEQ; 5720_M&R Grocery.doc CATLIN Engineers and Scientists
CATLIN Project No. 221043 9 June 2023
Monitoring Wells During the May 2023 monitoring event, groundwater samples from seven
monitoring wells (MW-1, MW-3, MW-4, MW-5, MW-6R, MW-7R, and MW-8R)
were collected and submitted for analysis via SM 6200B (including EDB, MTBE, and DIPE). Laboratory analysis did not detect any constituents above the laboratory reporting limits in the sample from MW-6R. No analyte concentrations were detected above GCL in any of the groundwater samples.
Analytical results reported the following constituents at concentrations above
their 2L GWQS in the following samples:
• MW-1: benzene, ethylbenzene, isopropylbenzene, naphthalene, n-propylbenzene, toluene, 1,2,4-trimethylbenzene, 1,3,5-
trimethylbenzene, and total xylenes;
• MW-4: benzene, naphthalene, n-propylbenzene, and total xylenes;
• MW-5: benzene, ethylbenzene, naphthalene, n-propylbenzene,
toluene, 1,2,4-trimethylbenzene, and total xylenes;
• MW-7R: benzene, p-isopropyltoluene, naphthalene, n-propylbenzene, and 1,2,4-trimethylbenzene; and
• MW-8R: benzene.

Equipment Rinsate Blank and Trip Blank One equipment blank (EB) and one trip blank (TB) were submitted for SM
6200B analysis. An estimated (“J”-value) concentration of acetone (a common laboratory artifact) was detected in the equipment blank sample. No additional targeted analytes were detected in the equipment blank sample. No targeted analytes were detected in the trip blank sample.
6.4 EVALUATION OF ASSESSMENT INFORMATION Extent of Contamination
Several petroleum constituents were detected above their respective 2L GWQS in samples from MW-1, MW-4, MW-5, and MW-7R. Only benzene was above its 2L GWQS in the MW-8R sample. No targeted analytes were above GCL. A summary of monitoring well groundwater sample analytical results are illustrated on Figure 5. The estimated extents of benzene and
naphthalene are provided in Figures 6 and 7, respectively. Currently, the groundwater plume is neither horizontally nor vertically delineated. The highest dissolved phase concentrations of petroleum constituents have historically been reported in samples from MW-1, MW-5, and MW-7R.
Contaminant concentrations have decreased in samples from MW-1 and MW-7R, increased in MW-5, and fluctuated in MW-3, MW-4, and MW-8R.

CATLIN Project No. 221043 10 June 2023
Cleanup Levels Achieved Soil – On June 5, 1990, one soil sample was collected in the vicinity of the
UST system. Analytical results revealed a total xylene concentration above
the STGW MSCC. Eight additional soil samples collected in July 1990 revealed TPH GRO concentrations below the State Action Levels (S&ME, 2019).
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 2004 (S&ME, 2019).
7.0 CONCLUSIONS AND RECOMMENDATIONS
Conclusions
Groundwater monitoring findings for this period are summarized below:
• Seven monitoring wells (MW-1, MW-3, MW-4, MW-5, MW-6R, MW-7R, and MW-8R) were sampled.
• The groundwater flow direction is generally towards the west-northwest.
• No analyzed compound concentrations were detected above the laboratory reporting limits in the sample from MW-6R.
• Several petroleum constituents above their 2L GWQS were reported in the
samples from MW-1, MW-4, MW-5, and MW-7R. Only benzene was above 2L GWQS in the MW-8R sample.
• The horizontal extent of groundwater contamination is not defined to the
north of either MW-1/TMW-01 location or to the southwest of MW-7R. The vertical extent of contamination is not defined.
• No targeted analytes were above GCL in any of the monitoring well samples.
• The concentrations of petroleum contaminants in monitoring wells MW-3,
MW-1 and MW-7R were generally lower than the September 202 sampling event. However, contaminant concentrations have increased in monitoring well MW-5 and fluctuated in MW-3, MW-4, and MW-8R.
• The groundwater plume is neither horizontally nor vertically delineated.

Recommendations CATLIN recommends to:
• Continue to make attempts to get permission to abandon the two inactive water supply wells (WSW-1 and WSW-2) within 250 feet of the subject site; and
• Conduct an annual groundwater sampling event in May 2024.

*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 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
