2 Land Use

Property Containing Source Area of Release

The questions below pertain to the property containing the source area of the release.

1. Does the property contain one or more primary or secondary residences (permanent or
temporary)? NO

Describe. The property is developed with a convenience store and active UST system
(Figure 2).

2. Does the property contain a school, daycare center, hospital, playground, park, recreation
area, church, nursing home, or other place of public assembly? NO

Describe. The property is developed with a convenience store.

3. Does the property contain a commercial (e.g., retail, warehouse, office/business space,
etc.) or industrial (e.g., manufacturing, utilities, industrial research and development,
chemical/petroleum bulk storage, etc.) enterprise, an inactive commercial or industrial
enterprise, or is the land undeveloped? YES

Describe. The property is developed with a convenience store.

3. Do children visit the property? YES

Explain. The property is developed with convenience store and children visit the site since
access is not restricted.

4. Is access to the property reliably restricted consistent with its use (e.g., fences, security
personnel or both)? NO

Explain. Access restrictions are not deemed necessary.

5. Do pavement, buildings, or other structures cap the contaminated soil? YES

If yes, explain what mechanisms are in place or can be put into place to ensure that the
contaminated soil will remain capped in the foreseeable future.

The remaining impacted soil is located in an area of the site overlain by asphalt and the
building. Due to the extent of the impacted soil not having been delineated, it is unknown if
the remaining impacted soil is capped by the building.

C RECEPTOR INFORMATION

1 Water-Supply Wells

Twenty-two water-supply wells were identified within approximately 1,000 feet of the
subject site (Table B-5 and Figure 4). It is Progress’ understanding that municipal water is
not available in the vicinity of the site; therefore, each nearby residence or business
utilizes a water-supply well. Based on municipal water not being available in the vicinity
of the site, Progress did not mail water-supply well information request.

2 Public Water Supplies

Are public water supplies available within 1,500 feet of the source are of the release? NO

If yes, where is the location of the nearest public water line and the source(s) of the public
water supply?

3 Surface Water

An unnamed pond is located approximately 1,350 feet to the southwest of the source area.

4 Wellhead Protection Areas

The source area is not located within an established wellhead protection area.

5 Deep Aquifers in the Coastal Plain Physiographic Region

The subject site is not located in the Coastal Plain Physiographic Province.

6 Subsurface Structures

Overhead electrical and phone utility lines service the subject site. Subsurface utilities
were not identified in the vicinity of the former UST system.

7 Property Owners and Occupants

Inez Saunders Wrenn currently owns the subject property. Adjacent properties are either
developed with residential or commercial properties. The names and addresses of the
adjacent property owners are provided in Table B-6 and referenced on Figure 3.

D SITE GEOLOGY AND HYDROGEOLOGY

According to the Geologic Map of North Carolina, the subject site is located in the Carolina
Stale Belt of North Carolina. The rocks beneath the site have been characterized as
metamorphosed granitic rocks. Groundwater generally 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 and the relatively
shallow depths to bedrock, 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
an east-west trending 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 southeast toward an
intermittent tributary of Stony Creek. (Figure 1).

E SAMPLING RESULTS

1 Soil

Progress did not collect soil samples for vertical delineation purposes during the Phase II
LSA due to the depth to groundwater being measured at approximately one foot below the
base of the previous excavation.

2 Groundwater

A permanent monitoring well (MW-1) was installed in the location shown on Figure 6
during the LSA activities using a Geoprobe® drill rig and solid-stem augers on October
22, 2014 by 3D. Approximately 0.69 feet of free product was detected in monitoring well
MW-1 during the additional well installation activities on November 11, 2014. Based on
the presence of free product and the apparent presence of water-supply wells within 1,000
feet of the source area, three additional monitoring wells (MW-2, MW-3, and MW-4) were
installed on November 11, 2014 in an effort to horizontally delineate the plume of
impacted groundwater. Well construction information is provided in Table B-7. The Non-
Residential Well Construction Records, which include boring logs, are included in
Appendix A.

Progress returned to the site on November 12, 2013 to collect groundwater samples from
monitoring wells MW-2 through MW-4. Monitoring well MW-1 was not sampled due to
the presence of free product. The groundwater samples were decanted into laboratory-
supplied bottles and placed into a cooler packed with ice. The cooler was delivered under
chain-of-custody to Research and Analytical Laboratories, Inc. (R&A) in Kernersville,
North Carolina for testing. R&A analyzed the groundwater samples for volatile organic
compounds (VOCs) by EPA Method 602, for semi-volatile organic compounds (SVOCs)
using EPA Method 625BNA plus ten tentatively identified compounds (TICs), and for
volatile and extractable petroleum hydrocarbons (VPH) by the Massachusetts Department
of Environmental Protection (MADEP) Methods. A summary of the groundwater sample
analytical results is included in Table B-4. The groundwater sample was collected using the
methods described in Appendix B.

Laboratory analysis of the groundwater samples collected from monitoring wells MW-2
through MW-4 did not detect targeted compounds above their North Carolina 2L
Groundwater Quality Standards (NC2LGWQS). Laboratory analysis of the groundwater
sample collected from monitoring well MW-2 detected C9-C22 Aromatics (111 µg/L).
Laboratory analysis of the groundwater sample collected from monitoring well MW-3 did
not detect targeted compounds at concentrations exceeding the laboratory detection limits.
Laboratory analysis of the groundwater sample collected from monitoring well MW-4
detected ethylbenzene (1.94 µg/L), toluene (2.15 µg/L), total xylenes (12.3 µg/L), C9-C18
Aliphatics (402 µg/L), and C9-C22 Aromatics. The laboratory analytical report for the
groundwater samples is provided in Appendix C.

Prior to sampling, the wells were developed until the development water ran relatively
clear, and the well was purged of an additional three casing volumes of water prior to
sampling. The depth to the groundwater surface in each of the wells was measured prior
to well purging using a decontaminated electric sounder. The wells were surveyed by
Progress using a relative benchmark that was arbitrarily given an elevation of 100 feet.
The elevations of the monitoring wells and the groundwater surface are both relative to
that benchmark. The relative groundwater elevations are shown in Table B-7.
Groundwater elevations are depicted on Figure 5. Based on information collected during
the Phase II LSA, the groundwater flow direction appears to be generally to the south-
southwest beneath the site.

F CONCLUSIONS AND RECOMMENDATIONS

Our findings are as follows:

1. The site meets the criteria for a High Risk classification based on the presence of active
drinking water-supply wells within 1,000 feet of the site. The site is not within a wellhead
protection area.

2. Progress did not collect a groundwater sample from monitoring well MW-1 due to the
presence of approximately 0.69 feet of free product. Progress installed monitoring wells
MW-2 through MW-4 on November 11, 2014 and returned to collect groundwater samples
from monitoring wells MW-2 through MW-4 on November 12, 2014. Laboratory analysis
of the groundwater samples collected from monitoring wells MW-2 through MW-4 did not
detect targeted compounds above their respective NC2LGWQS.

3. Progress recommends that the current property owner be notified and a copy of this report be
submitted to the Winston-Salem Regional Office of the NCDENR, Division of Waste
Management, UST Section. Progress recommends the completion of a Mobile Multi-Phase
Extraction (MMPE) event followed by a groundwater sampling event, as part of a Pre-
Corrective Action Plan Monitoring Report and prior to a Comprehensive Site Assessment in
an effort to remove the free product from the vicinity of monitoring well MW-1.

G FREE PRODUCT INVESTIGATION/RECOVERY

Approximately 0.69 feet of free product was detected in monitoring well MW-1 on
November 11, 2014.

H SITE HISTORY

Progress was contracted by Eden Oil Company to conduct UST closure activities at the
Pagetown Exxon located at 8035 Cherry Grove Road South in Reidsville, Caswell County,
North Carolina (Figure 1). The site consists of a convenience store which stores
petroleum products in USTs for retail sale. Prior to removal of the UST systems,
aboveground storage tanks were installed to store the kerosene and diesel fuel. The site is
located in a commercial and residential area of rural Caswell County. The surrounding
properties are served by water-supply wells within 1,500 feet of the source area. The
closure activities included the removal of one 1,000-gallon kerosene UST and one 2,000-
gallon diesel UST.

An Initial Abatement Action Report was submitted to the NCDENR on July 24, 2014.
Information regarding the on site USTs is presented below:

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.
