CATLIN Project No. 221233 2 April 2023
2.0 EXECUTIVE SUMMARY
The M&M Grill site is located at 217 E. South Main Street, Littleton, Halifax County,
North Carolina. Ten underground storage tanks (USTs) were previously operated at
the site. One 1,000-gallon waste oil, two 3,000-gallon gasoline, one 4,000-gallon gasoline, two 550-gallon heating oil, and four 550-gallon USTs with unknown last contents were removed from the site in 2021. A petroleum release was discovered during tank closure activities.

The purpose of this report is to document the latest remediation efforts and groundwater sampling activities. On February 7, 2023, CATLIN Engineers and Scientists (CATLIN) personnel coordinated with Eastern Environmental Management, LLC (EEM) to conduct an aggressive fluid vapor recovery (AFVR)
event utilizing monitoring wells MW-02 and MW-03. A total of 625 gallons of
impacted groundwater were recovered and a calculated 6.84 pounds of petroleum vapors (equivalent to 1.09 gallons of petroleum) were emitted. CATLIN returned to the site on March 15, 2023 and measured groundwater at
approximately eight feet deep across the site in the shallow wells. Groundwater
samples from five monitoring wells were collected. The samples were 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 reported one or more VOCs in the MW-01D, MW-02, MW-03, and MW-04 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). Benzene was also reported above its Gross
Contaminant Levels (GCL) in the MW-03 sample. Low or estimated concentrations
(“J”-values) of some VOCs were detected in the MW-01 sample, but they were all below their 2L GWQS. Benzene, toluene, ethylbenzene, and total xylenes (BTEX) concentrations appear to
have decreased in samples from shallow monitoring wells MW-02, MW-03, and
MW-04, and deep well MW-01D since the previous sampling event in December 2022. In order to help reduce groundwater contaminant concentrations to below GCL,
CATLIN recommends to:
• Conduct a mobile multi-phase extraction (MMPE) event utilizing wells MW-02, MW-03 and MW-04 as extraction points; and
• Conduct an additional sampling event following the MMPE event.

3.0 SCOPE OF SERVICES The scope of services for this report was performed in general accordance with
CATLIN proposal number 221233.04P, dated January 5, 2023. Services were
authorized by the North Carolina Department of Environmental Quality’s (NCDEQ’s) Task Authorization (TA) #04, accepted on January 9, 2023, and Contract Number N122019D.
The approved scope of services for this Task Authorization included to:
• Coordinate and oversee an AFVR event utilizing monitoring wells MW-02 and MW-03 as extraction points;
• Approximately 30 days after the event, gauge and sample five monitoring wells (MW-01, MW-01D, MW-02, MW-03, and MW-04);
• Analyze six water samples (five monitoring wells and one field blank) per SM 6200B (plus EDB, MTBE, and DIPE); and
• Prepare a monitoring report summarizing the findings. The scope of services was conducted in general accordance with the approved TA.
4.0 SITE HISTORY AND CHARACTERIZATION
The M&M Grocery site is located at 217 E. South Main Street, Littleton, Halifax County, North Carolina (Figures 1 and 2). Summarized available historical sampling and gauging data are provided in Appendix A. Site photographs are presented in
Appendix B.
4.1 UST OWNER AND OPERATOR INFORMATION Ten USTs were historically operated at the site. The owners and operators of
the tanks are unknown. All the USTs were removed from the site on April 5,
2021 (MAA, 2021). Available UST information is presented on Table 1.
4.2 UST INFORMATION
Based on information provided in the tank closure report and according to the NCDEQ UST database, two 3,000-gallon gasoline USTs were installed at the site in 1956 and one 4,000-gallon gasoline UST was installed in 1971. During
UST closure activities in April 2021, seven additional orphan USTs were
discovered. The tanks had reportedly been inactive for the past 20 years, but the exact dates of operation are unknown (MAA, 2021). Due to the lack of a responsible party, the site was accepted into the State
Lead program in June 2021 (NCDEQ, 2021).
Available UST information is presented on Table 1 and the approximate former UST locations are illustrated on Figure 3.
NCDEQ; 47687_M&M Grill CATLIN Engineers and Scientists
CATLIN Project No. 221233 4 April 2023
4.3 CONTAMINANT SOURCE INVENTORY A petroleum release was discovered on April 5, 2021 during tank closure
activities. Soil samples were collected from the sidewalls of one excavation
and the bottom of another. Laboratory analytical results from several of the samples revealed total petroleum hydrocarbons (TPH) gasoline- and diesel-range organics (GRO and DRO) at concentrations exceeding their State Action Levels. Groundwater samples were not collected at the time of the
UST closure, but impacted groundwater was noted in one of the excavations
(MAA, 2021). 4.4 SITE CHARACTERISTICS
The site is currently owned by Casa Mia’s, Inc. and is a vacant lot which is
used as parking for the adjacent restaurant. The former M&M Grill structure was demolished on April 5, 2021, prior to UST removal activities. Site photographs are presented in Appendix B.
4.5 OWNERS AND OCCUPANTS OF ADJOINING/NEARBY PROPERTIES AND LAND USE Properties in the site vicinity are mostly businesses and residences. The subject site is bound by E. South Main Street to the south and west, and
Plant Street to the north. The parcels to the north of the site (across Plant
Street) are commercial businesses. The southern adjacent parcel (across E. South Main Street) is occupied by a gas station and an associated drive through car wash; residential properties are further to the south.
4.6 RECEPTOR INFORMATION
The most recent receptor survey for the M&M Grill site was conducted by CATLIN in August 2021. Pertinent receptor information is summarized below. Potential receptors are illustrated on Figure 2 and receptor information
obtained from CATLIN (2021) is shown on Table 2.
Based on utility data obtained from the Town of Littleton, municipal water is available to the site vicinity. One inactive non-potable well was identified approximately 890 feet north-northwest of the source area (upgradient of the
site).
No surface water bodies were identified within 1,500 feet of the site during the last receptor survey.
4.7 PREVIOUS INVESTIGATIONS AND REMEDIAL ACTIVITIES
An Underground Storage Tank Closure Report was prepared by Mid-Atlantic Associates Engineering & Environmental Solutions (MAA) on behalf of the Upper Coastal Plain Council of Governments (UCPCOG) and submitted on
NCDEQ; 47687_M&M Grill CATLIN Engineers and Scientists
CATLIN Project No. 221233 5 April 2023
May 3, 2021. A UST-61 24-Hour Release and UST Leak Reporting Form was submitted on April 8, 2021.
CATLIN conducted a Limited Site Assessment (LSA) in 2021. A receptor
survey was conducted, and two shallow monitoring wells (MW-01 and MW-02) were installed and sampled. The groundwater samples were submitted for analysis via SM 6200B (plus EDB, MTBE, and DIPE), Environmental Protection Agency (EPA) Method 625 [(plus base, neutrals,
and acids (BNA) and tentatively identified compounds (TICs)],
Massachusetts Department of Environmental Protection (MADEP) Method for volatile petroleum hydrocarbons (VPH) and extractable petroleum hydrocarbons (EPH), and lead per EPA Method 6020B. Analytical results revealed multiple VOC, SVOC, and MADEP VPH/EPH concentrations above
their corresponding 2L GWQS in the groundwater sample from MW-02, but
none above 2L GWQS in the sample from MW-01. Both samples contained lead above its 2L GWQS. No targeted analytes were detected above GCL (CATLIN, 2021).
In April 2022, CATLIN installed two shallow/Type II monitoring wells (MW-03
and MW-04) and one deep/Type III monitoring well (MW-01D), followed by groundwater sampling in May 2022. Groundwater samples from the five monitoring wells (MW-01 through MW-04 and MW-01D) were collected and analyzed per SM 6200B and EPA Method 625. Laboratory results indicated
multiple VOCs and semi-VOCs in the MW-01D, MW-02, MW-03, and MW-04
samples at concentrations above 2L GWQS; however, none were above GCL. Contaminant concentrations had decreased in MW-02 since the August 2021 sampling event (CATLIN, 2022).
CATLIN conducted a sampling event in December 2022. Laboratory analysis
indicated several VOCs above 2L GWQS in the samples from MW-01D, MW-02, MW-03, and MW-04. Benzene was also reported at a concentration above its GCL in the MW-03 sample. Contaminant concentrations had increased in shallow monitoring wells MW-02 and MW-03, but decreased in
deep well MW-01D (CATLIN, 2023). 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.
NCDEQ; 47687_M&M Grill CATLIN Engineers and Scientists
CATLIN Project No. 221233 6 April 2023
The site is underlain by terrace deposits and upland sediment from the Coastal Plain belt. According to the 1985 Geologic Map of North Carolina, gravel, clayey sand, and sandstone are exposed in the site area.

According to the well logs in CATLIN (2021), an artificial brown silty sand underlies the site to approximately five feet below land surface (BLS). A brown lean clay with trace sand was encountered from five to ten feet BLS. Mottled silt was encountered at further depths to boring termination.
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 – No surface water bodies were identified within 1,500 feet of the site.
6.0 SITE ASSESSMENT INFORMATION
CATLIN conducted field activities on February 7 and March 15, 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 on electronic Job Hazard Analysis (JHA) forms. The JHA forms are
included in Appendix C. Photographs from the site visits are presented in Appendix B. CATLIN personnel gauged and collected groundwater samples for laboratory
analysis of VOCs per SM 6200B from five monitoring wells (MW-01, MW-01D, MW-02, MW-03, and MW-04). Well locations and site features are shown on Figure 3 and well construction details are presented on Table 3. 6.1 AFVR EVENT
CATLIN mobilized to the site on February 7, 2023 to supervise an AFVR event conducted by EEM. The event was conducted for a duration of eight hours utilizing monitoring wells MW-02 and MW-03 as extraction points. Prior to the event, CATLIN personnel gauged the monitoring wells and the depth to
water was 8.32 feet below top of casing (BTOC) in MW-02 and 8.94 feet BTOC in MW-03. Light non-aqueous phase liquid (LNAPL) was not encountered in the wells. A total of 625 gallons of impacted groundwater were removed from the
subsurface. The vacuum at the recovery pump ranged from 21 to 20 inches of mercury. Airflow rates ranged from 641 to 195 feet per minute with an average of approximately 267 feet per minute. The system temperature ranged from 54 to 150 degrees Fahrenheit and humidity stabilized at 100 percent. Field-gauged VOCs ranged from 1,174 parts per million (ppm) to
NCDEQ; 47687_M&M Grill CATLIN Engineers and Scientists
CATLIN Project No. 221233 7 April 2023
2,484 ppm throughout the event. A calculated 6.84 pounds of petroleum vapors were emitted during this event, equivalent to approximately 1.09 gallons of petroleum.

Gauging results are presented on Table 3. Emissions calculations are included in Appendix D. Disposal documents are presented in Appendix E. 6.2 GAUGING DATA

Depth to water at the M&M Grill site has ranged from 7.63 feet BTOC (MW-02) to 11.06 feet BTOC (MW-01). During the previous monitoring period, groundwater flow direction was calculated to be towards the southeast (CATLIN, 2023).

During the March 2023 sampling event, CATLIN personnel measured depth to water in five 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 North Carolina Department of Environmental and Natural Resources (NCDENR) and NCDEQ Guidelines, and EPA Region 4 Operating Procedures.

Depth to water ranged from 7.55 feet BTOC (MW-04) to 8.68 feet BTOC (MW-01) in the shallow/Type II wells and was 8.11 feet BTOC in the deep/Type III well (MW-01D). LNAPL was not encountered during this sampling event. Based on groundwater elevations calculated for this
monitoring period, groundwater flow direction continues to be towards the
southeast. Monitoring well gauging results for events conducted by CATLIN are presented in Table 3. Groundwater elevations are illustrated on Figure 4 and
groundwater sampling forms are provided in Appendix C. 6.3 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 1.17.12). The Aqua TROLL was decontaminated according to manufacturer’s recommendations and rinsed with distilled water between use at each
NCDEQ; 47687_M&M Grill CATLIN Engineers and Scientists
CATLIN Project No. 221233 8 April 2023
monitoring well. Groundwater parameter data were transferred from the VuSitu mobile application to the electronic groundwater sampling forms. Copies of the groundwater sampling forms are available in Appendix C.

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

A field blank was collected by pouring water from a new, sealed gallon of distilled water directly into laboratory-provided, pre-preserved glassware. The glassware was labeled and placed on ice in an insulated cooler.
The groundwater samples and field 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 F.
6.4 SUMMARY OF GROUNDWATER INFORMATION During the previous monitoring event (December 2022), samples from MW-01, MW-01D, MW-02, MW-03, and MW-04 contained petroleum
constituent concentrations above 2L GWQS. Benzene was reported above its GCL in the sample from MW-03. The latest groundwater sampling laboratory results for SM 6200B analysis are summarized in Table 4. Historical results from samples collected by
CATLIN are included in Tables 5 and 6. Monitoring well sample analytical results are presented on Figure 5. A copy of the complete laboratory report and COC documentation are in Appendix F. Monitoring Wells
During the March 2023 monitoring event, five monitoring well groundwater samples (MW-01, MW-01D, MW-02, MW-03, and MW-04) were collected and submitted for analysis via SM 6200B (including EDB, MTBE, and DIPE). Laboratory analysis did not detect any constituents above their respective 2L
GWQS limits in the sample from MW-01. Benzene was above its GCL in the MW-03 sample. Analytical results reported the following constituents at concentrations above their 2L GWQS in samples MW-01D, MW-02, MW-03, and MW-04:
• MW-01D: benzene;
• MW-02: benzene, n-butylbenzene, ethylbenzene, naphthalene, n-propylbenzene, toluene, 1,2,4-trimethylbenzene, and total xylenes;
• MW-03: benzene (GCL exceedance), ethylbenzene, naphthalene, n-
propylbenzene, toluene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, and total xylenes; and
NCDEQ; 47687_M&M Grill CATLIN Engineers and Scientists
CATLIN Project No. 221233 9 April 2023
• MW-04: benzene, ethylbenzene, naphthalene, n-propylbenzene, styrene, toluene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, and
total xylenes.

Field Blank One field blank sample was submitted for analysis per SM 6200B (including
EDB, MTBE, and DIPE). An estimated (“J”-value) concentration of acetone (a
common laboratory artifact) was detected. No other targeted analytes were detected. 6.5 EVALUATION OF ASSESSMENT INFORMATION

Extent of Contamination Several petroleum constituents were detected above their respective 2L GWQS in samples from MW-01D, MW-02, MW-03, and MW-04. Benzene
was above its GCL in the MW-03 sample. A summary of monitoring well
groundwater sample analytical results are illustrated on Figure 5. The estimated horizontal extent of benzene is shown on Figure 6. The contaminant plume has not been horizontally or vertically delineated.
Historically, the highest BTEX concentrations were reported in the samples
from MW-02, MW-03, and MW-04. Based on the most recent results, the BTEX concentrations in samples obtained from MW-01D, MW-02, MW-03, and MW-04 appear to have decreased since the December 2022 event.

Cleanup Levels Achieved
Soil – Approximately 121 tons of impacted soil were removed from the site during tank closure activities; however, over-excavation of additional
impacted soil was not permitted under the terms of the work authorization at
the time of the UST removals. Analysis of tank closure soil samples indicated that TPH GRO and DRO concentrations were above State Action Levels (MAA, 2021).
Groundwater – Groundwater contaminant concentrations are above 2L
GWQS, and benzene was detected above the GCL in the sample from MW-03.
LNAPL – LNAPL has never been observed at the site.

7.0 CONCLUSIONS AND RECOMMENDATIONS Conclusions

Groundwater monitoring findings for this period are summarized below:
• An AFVR event was conducted utilizing monitoring wells MW-02 and MW-03. A total of 625 gallons of impacted groundwater were recovered and 6.84
pounds of petroleum vapors (equivalent to 1.09 gallons of petroleum) were
emitted.
• Approximately 30 days after the AFVR event, groundwater samples were collected from five monitoring wells (MW-01, MW-01D, MW-02, MW-03, and
MW-04) and analyzed via SM 6200B (including EDB, MTBE, and DIPE).
• Multiple petroleum constituent concentrations were reported above their respective 2L GWQS in the samples from shallow wells MW-02, MW-03, and MW-04.
• Benzene was reported above its 2L GWQS in deep well MW-01D.
• Benzene was above its GCL in the MW-03 sample.
• Groundwater flow direction is toward the southeast.
• Contaminant concentrations in MW-01D, MW-02, MW-03, and MW-04 have decreased since the December 2022 event.
• The groundwater plume has not been delineated.

Recommendations In order to help reduce groundwater contaminant concentrations to below GCL,
CATLIN recommends to:
• Conduct a MMPE event utilizing wells MW-02, MW-03 and MW-04 as extraction points; and
• Conduct an additional sampling event following the MMPE event.
