GROUNDWATER SAMPLING

Three temporary monitoring wells were installed on May 16, 2019 at the locations shown on
the attached exhibit: W-5 is located at a suspected former location of a UST; W-6 is located at a
suspected former location of a UST; and W-7 is located at the rear of the building to obtain
background data.

All monitoring wells were constructed in accordance with 15A NCAC 2C .0100 utilizing hollow
stem auger drilling, 2-inch PVC casing and screen, filter sand, bentonite seal, well cap and
concrete pad. Well Construction Records for each monitoring well are attached.

On May 17, 2019 each well was sampled. The top of casing elevation and ground elevation was
surveyed at each well location and the groundwater elevation was measured at each location
to determine groundwater flow across the property. Each well was developed by removal of
10-gallons of water from each well. A volume of 0.5 gallons of water was removed prior to
sampling Well W-5. The sample was slightly turbid. A volume of 1.5 gallons of water was
removed prior to sampling Well W-6. The water would not clear up; the sample was turbid. A
volume of 0.5 gallons of water was removed prior to sampling Well W-7. The sample was
slightly turbid.

Groundwater samples were obtained using new weighted hand bailers. The field technician
used a new pair of latex gloves for each water sample collected and took specific precautions to
ensure no cross-contamination occurred. Samples were transported to the laboratory for
analyses for Volatile Organic Compounds (VOCs) by EPA Method 8260, Semi-VOCs (SVOCs) by
EPA Method 8270, and Resource Conservation and Recovery Act (RCRA) metals by EPA Method
6020. Chain-of-custody forms were maintained for each sample and are attached for reference.

Chromium was detected in monitoring well W-5 at a concentration in excess of the 2L Standard.
Barium, Lead, Selenium and TCE were detected in monitoring well W-6 at concentrations in
excess of the 2L Standards. Chromium and TCE were detected in monitoring well W-7 at
concentrations in excess of the 2L Standards. Laboratory analytical results are attached. A
summary table of analytical results is shown on the following page.

A land survey was performed to record the exact location and elevation of each monitoring well
installed. Horizontal location is referenced to North Carolina State Plane, NC Grid,
NAD83(2011). Elevation information is feet above mean sea level, referenced to NAVD88. The
depth to groundwater was measured at each monitoring well. The groundwater elevation was
calculated for each monitoring well location. Based on the data collected, the direction of
groundwater flow gradient is in a southerly direction, from W-5 to W-7.

SOIL SAMPLING

On May 16, 2019 three soil samples, S-9A, S-9B and S-9C were collected at a depth of 0 to 2 feet
below the ground surface utilizing a hand auger at the proposed borrow area shown on the
attached exhibit where it is anticipated that no more than 1,000 cubic yards of soil is proposed
to be moved to fill a ditch and regrade to provide positive drainage. Each sample was screened
utilizing a Photoionization Detector (PID) and one sample was selected based on visual,
olfactory, and PID readings for VOC analysis. The three samples were composited in the
laboratory and the composite sample, S-9, was analyzed for VOCs by EPA Method 8260, SVOCs
by EPA Method 8270, and RCRA metals by EPA Method 6020. The grab sample was not
analyzed by the laboratory for VOCs as planned.

On October 16, 2019 three additional soil samples, S-16A, S-16B and S-16C were collected at a
depth of 0 to 2 feet below the ground surface utilizing a hand auger at the proposed borrow
area shown on the attached exhibit. Each grab sample was analyzed for VOCs by EPA Method
8260. The three samples were composited in the laboratory and the composite sample, S-16,
was analyzed for SVOCs by EPA Method 8270, and RCRA metals by EPA Method 6020.

Two soil samples were collected at the three monitoring well locations shown on the attached
exhibit on May 16, 2019. Samples were collected utilizing Direct Push Technology (DPT). The
first sample was collected at a depth of 0 to 2 feet below the ground surface. The second
sample was collected a depth greater than 2 feet below the ground surface but above the
water table, based on visual, olfactory, and/or PID readings. Each sample was analyzed for VOCs
by EPA Method 8260, SVOCs by EPA Method 8270, and RCRA metals by EPA Method 6020.

Field soil sampling kits provided by the laboratory consisting of sterile sample containers with
preservatives as necessary were used. The field technician used a new pair of latex gloves for
each soil sample collected and took specific precautions to ensure no cross-contamination
occurred. Samples were transported to the laboratory for analyses. A chain-of-custody form
was maintained for each sample and is attached for reference.

At the proposed borrow area, Chromium was detected in sample S-9 and sample S-16 at
concentrations in excess of the Preliminary Soil Remediation Goal (PSRG) for both Protection of
Groundwater and Industrial/Commercial Health Based PSRG.

At the proposed borrow area, Silver was detected in sample S-9 and sample S-16 at
concentrations in excess of the PSRG for Protection of Groundwater but below the
Industrial/Commercial Health Based PSRG.

SOIL-GAS VAPOR SAMPLING

On May 15, 2016 seven soil-gas samples were collected from beneath the bottom of the
concrete floor slab of the building at locations shown on the attached exhibit. A hammer drill
was used to drill holes in the concrete floor slab at the sample locations. Prior to collecting the
soil-gas samples, a leak test was performed on the sample point and sample train fittings using
a stainless-steel shroud, helium gas, and a helium gas detector. Samples were collected from
each sample point in a cannister at a flow rate of approximately 200 mL/min. Upon completion
of sampling, sample points were sealed with grout and abandoned. Each sample was
transported to the laboratory and analyzed for VOCs by EPA Method TO-15.

TCE was detected in sample V-4 at a concentration in excess of the Sub-slab Soil Gas Screening
Level. A summary table of analytical results is shown below. A chain-of-custody form was
maintained for each sample and is attached. Laboratory analytical results are attached.
