B SITE HISTORY AND CHARACTERIZATION
Progress Environmental Group, Inc. (Progress) was contracted by McLeod Oil Company, Inc. to
conduct underground storage tank (UST) closure activities at the West 70 Curb Market located at
110 Woodlawn Road in Mebane, Alamance County, North Carolina (Figure 1). The site consists of
a former convenience store which stored petroleum products in USTs for retail sale. At the time of
the removal the site was undergoing remodeling, and the USTs had not been used to store petroleum
product since 2005. The site is located in a mixed use area of Mebane, including commercial,
residential, and industrial uses.It is likely that the surrounding properties are served by the Town of
Mebane municipal water-supply system. The closure activities included the removal of one 1,000-
gallon gasoline UST and one 4,000-gallon gasoline UST and associated piping. Information
regarding the on-site USTs is presented below:

Based on the results of the initial abatement activities, Progress concluded the following:
Progress supervised the removal of one 1,000-gallon gasoline UST and one 4,000-gallon UST, and
associated fuel dispensing lines from the subject site.
Progress collected a total of five soil samples beneath the gasoline USTs (S-1 through S-5).
Laboratory analysis of soil samples S-3 (23,500 mg/Kg) and S-4 (3,720 mg/Kg) collected beneath
the USTs indicated Total Petroleum Hydrocarbons as Gasoline (TPH-G) concentrations in excess
of the North Carolina Action Level.
Progress collected a total of two soil samples beneath the dispensers (S-6 and S-7). Laboratory
analysis of soil sample S-6 (1,720 mg/Kg) collected from beneath the northernmost dispenser
indicated TPH-G concentrations in excess of the North Carolina Action Level.
Progress collected one soil sample beneath the fuel distribution lines (S-8). Laboratory analysis of
soil sample S-8 (2,740 mg/Kg) collected from beneath the fuel distribution lines indicated TPH-G
concentrations in excess of the North Carolina Action Level.
Based on the presence of notably contaminated soil, Progress supervised the over-excavation of
contaminated soil beneath the USTs. Soil samples were screened using Redlabs mobile laboratory
to complete the guided excavation. Approximately 484.07 tons of petroleum-impacted soil were
excavated from the site and transported to an off-site permitted disposal facility.

Following the over-excavation of the contaminated soil, Progress screened the soil samples from
the sidewalls of the excavation via Redlabs mobile laboratory. Each of the soil samples selected
for laboratory analysis did not exhibit TPH as gasoline at concentrations exceeding the North
Carolina Action Level when analyzed using the UVF Method. Progress collected confirmation
soil samples from the sidewalls and base of the over-excavation. Prior to collecting the soil samples
laboratory analysis of soil samples SW-1 and SW-6 collected from the sidewalls of the over-
excavation did not detect targeted compounds above their respective Soil-to-Groundwater
Maximum Soil Contaminant Concentrations (MSCCs) or Residential Soil Cleanup Levels.
Laboratory analysis of soil samples SW-2 through SW-5 and SW-7 through SW-12 collected from
the sidewalls and soil samples B-1 through B-4 collected from the base of the over-excavation
detected at least one targeted compound above its respective Soil-to-Groundwater MSCC. C9-C10
Aromatics were detected in soil sample B-3 at a concentration that exceeds its Residential Soil
Cleanup Level.

at 168 Woodlawn Road was confirmed via conversation with the property owner to be used
for irrigation and livestock watering. Each of the identified water-supply wells are located
more than 500 feet from the source area. An additional out of use well was identified more
than 1,000 feet from the source area and, therefore, was not included on Figure 4 or in Table
B-5. Copies of the returned water-supply well questionnaires are included in Appendix D.
Progress understands that public water is available in the vicinity of the site.
2 Public Water Supplies
Are public water supplies available within 1,500 feet of the source are of the release? YES
If yes, where is the location of the nearest public water line and the source(s) of the public
water supply? The public water lines are located within the adjacent rights-of-way. Please
note, properties proximal to the site are provided water by either the City of Mebane or the
Alamance-Orange Water System. The source of drinking water in the City of Mebane is
from the Graham-Mebane Reservoir (surface water supply). The Orange-Alamance Water
System include Corporation Lake, four water-supply wells, and purchased water from the City
of Burlington through the Town of Haw River. Lake Orange provides additional water during
drought conditions. The water-supply wells associated with the Alamance-Orange water
supply do not appear to be located proximal to the site.
3 Surface Water
According to the USGS topographic map, an unnamed pond is located approximately 1,400
feet to the west-northwest of the source area.
4 Wellhead Protection Areas
The source area is not located within an established wellhead protection area according to

7 Property Owners and Occupants
MACMOM, LLC. currently owns the subject property. Adjacent properties are developed
as commercial properties or are undeveloped. The names and addresses of the adjacent
property owners are provided in Table B-6.
E SITE GEOLOGY AND HYDROGEOLOGY
According to the Geologic Map of North Carolina (1985), the subject property is situated in
the Carolina Slate Belt of the Piedmont Physiographic Province of North Carolina. The site is
located in an area underlain by intermediate metavolcanic rock characterized by
metamorphosed andesitic tuffs and flows. In the Piedmont Physiographic Province,
groundwater generally occurs under water-table conditions and is stored in the pore space
between individual grains of residual soil and in the fractures within the underlying parent
rock. Due to the intense shearing associated with the thrust faulting in the area, it can be
expected that the fractures play a major role in the flow of groundwater in the subsurface.
Recharge to the water table is primarily by precipitation infiltrating the upper soils and
percolating downward, under the influence of gravity, to the groundwater table. Typically, the
water table is not a level surface, but a subdued reflection of the land surface. However, the
depth to the water table is not constant, and depends on many factors, which include the amount
of rainfall, the permeability of the soil, and the amount of groundwater being pumped in the
area.
Based on our review of the topographic map and on-site observation, the site is located on a
ridge. Groundwater generally flows in directions sub-parallel to the ground surface slopes
and under the influence of gravity toward points of discharge such as creeks, swamps,
drainage swales, or pumped groundwater wells. Based on topographic inference,
groundwater beneath the site most likely flows to the west.
Soil encountered during the UST removal included fine sandy silt. During the advancement
of the soil boring to install the monitoring well, Progress consistently encountered fine sandy
silt beneath the imported fill material (21 feet bls). Bedrock was not encountered during
drilling activities. Groundwater was encountered at an approximate depth of 18 feet bls in
the monitoring well installed on site. Groundwater flow beneath the site appears to be
migrating to the west. An unnamed pond is located approximately 1,400 feet to the west of
the source area (Figure 1).
F SAMPLING RESULTS
1 Soil
Based on the depth to groundwater being identified shallower than the former excavation of
contaminated soil, Progress did not collect a soil sample for laboratory analysis as part of
this assessment.

2 Groundwater
On January 15, 2021 3D Environmental Investigations, LLC installed one, two-inch
monitoring well (MW-1) to an approximate depth of 30 feet bls with 15 feet of 0.01 slotted
Schedule 40 PVC screen using the hollow stem auger drilling method. Following proper
well development and purging, Progress collected a groundwater sample from the
monitoring well using a disposable bailer and new length of cord and transferred to the
laboratory containers into a cooler packed with ice. The groundwater sample collected from
monitoring well MW-1 was analyzed for volatile organic compounds (VOCs) using
Standard Method 6200B, for ethylene dibromide using EPA Method 504.1, for lead using
the Standard Method, and for volatile petroleum hydrocarbons using the Massachusetts
Department of Environmental Protection (MADEP) Method.
Laboratory analysis of the groundwater sample collected from monitoring well MW-1
detected benzene (4,380 µg/L), chloroform (78.5 µg/L), ethylbenzene (1,410 µg/L), di-
isopropyl ether (317 µg/L), methyl tert-butyl ether (18,900 µg/L), toluene (14,300 µg/L),
1,2,4-trimethylbenzene (1,440 µg/L), total xylenes (7,660 µg/L), ethylene dibromide (1.1
µg/L), C5-C8 Aliphatics (57,100 µg/L), C9-C12 Aliphatics (22,000 µg/L), and C9-C10
Aromatics (6,350 µg/L) at concentrations exceeding their respective North Carolina 2L
Groundwater Quality Standards (NC2LGWQS). Please note, none of the detected
concentrations exceed the applicable Gross Contamination Levels (GCLs).
Copies of the laboratory data sheet and chain-of-custody record are included in the Appendix
D. The groundwater sample was collected using the methods described in Appendix A.
G CONCLUSIONS AND RECOMMENDATIONS
Based on the results of the receptor survey and groundwater sampling activities, Progress
makes the following conclusions:
1.The site meets the criteria for a Low Risk site based on the absence of active water-supply
wells being identified within 1,000 feet of the source area. The site is not located within a
wellhead protection area.
2.Based on the depth to groundwater being identified shallower than the former excavation of
contaminated soil, Progress did not collect a soil sample for laboratory analysis as part of
this assessment.
3.Laboratory analysis of the groundwater sample collected from monitoring well MW-1
detected benzene (4,380 µg/L), chloroform (78.5 µg/L), ethylbenzene (1,410 µg/L), di-
isopropyl ether (317 µg/L), methyl tert-butyl ether (18,900 µg/L), toluene (14,300 µg/L),
1,2,4-trimethylbenzene (1,440 µg/L), total xylenes (7,660 µg/L), ethylene dibromide (1.1
µg/L), C5-C8 Aliphatics (57,100 µg/L), C9-C12 Aliphatics (22,000 µg/L), and C9-C10
Aromatics (6,350 µg/L) at concentrations exceeding their respective NC2LGWQS. Please
note, none of the detected concentrations exceed the applicable GCLs.

APPENDIX A
STANDARD SAMPLING PROCEDURES
EXHIBIT A
Procedures for Developing the Monitoring Wells
Well development will be performed no sooner than 24 hours after well construction is completed.
Wells will be developed by bailing or pumping a minimum of five well-volumes of groundwater
from the well.
The turbidity, pH, specific conductivity, dissolved oxygen and temperature of the development
water will be measured and recorded, and used as an indicator parameter to determine the
completion of the development process.
EXHIBIT B
Procedures for Collecting Groundwater Samples
Each well will be purged of three standing well volumes prior to sample collection to remove
stagnant water from the well and well bore in an effort to collect samples that are representative of
the water quality in the formation surrounding each well.
Chemical preservatives, if applicable, will be added to sample bottles by the laboratory.
Sample bottles will be labeled prior to sample collection.
Sample bottles will be filled directly from the Teflon or disposable bailer. Volatile organic samples
will be collected first.
The pH, temperature, and specific conductance of the sample will be measured and recorded.
These measurements will be taken from a sample deposited in a separate container. Visual
characteristics of the sample, including insoluble materials, will be recorded.
Caps will be secured on bottles, bottle will be placed in plastic bags and the bags will be sealed.
Documentation, including Chain-of-Custody Record and laboratory analytical request form, will
be completed for all samples.
Samples will be packed in coolers with "bubble wrap" and ice packs for shipment.
Chain-of-Custody Record and analytical request form will be placed inside cooler sealed with
security tape.
Samples will be shipped via overnight express to the analytical laboratory within 24 hours
following collection.
Laboratory will be advised of each sample shipment.
