B. Executive Summary
A LSA was issued October 26, 2013. After review of the LSA, the DENR required annual
groundwater sampling. The three monitor wells and two water supply wells were sampled
January 21 and 24, 2020 for analysis by method 6200B. No compounds were detected in any of
the wells.

D. Site History and Characterization
Poplar Tent Service Station was closed and taken by the NCDOT for road construction, all but
the back of the property was secured. The back portion was sectioned off, named parcel 47, and
is currently owned by United Oil Company. Some old reports refer to the site as Parcel 47.
The UST facilities were removed by the NCDOT; contamination as high as 7060 ppm of
TPH/GRO was detected in the main UST basin. A LSA was required after the tank closure, but
the NCDOT constructed a road atop the former tank basin. The NCDENR determined that the
assessment could consist of three monitor wells installed in parcel 47. Monitor well -1 is within
fifteen feet (upgradient) of the former tank basin and MW-2 is in the eastern portion of the
former site building. Monitor well — 3 is in the southern (back - up gradient) portion of the
property, it was installed to establish the direction of groundwater flow.
E. Site Assessment Information
WSWs 1 & 2 and MW-1 were sampled January 21, 2020; MWs 2 & 3 were sampled January 24,
2020. Sampling was halted on January 21, 2020 due to an emergency call received before
MW-2 was fully purged. All five samples were non -detect. A historical sampling table is
attached; the lab analysis is on the accompanying CD.
The monitor well samples were obtained after first purging three well casing volumes with a
new, disposable bailer. The water supply wells were sampled after running the well taps for

fifteen minutes. For both sampling events the samples were placed in laboratory provided vials,
fixed with a chain of custody, and placed on ice for immediate delivery to PACE Analytical.
F. Free Product— not applicable
G. Soil Remediation — not applicable
H. Groundwater Remediation — not applicable
I. Conclusions
Petroleum compounds have not been detected in the monitor wells nor the water supply wells in
eight sampling events. A monitor well could not be installed directly into the source area due to
NCDOT construction. Monitor well 1 is directly upgradient of the former UST basin. Based on
the LSA and the follow up sampling, it appears that the soil contamination detected by the
closure has not impacted the groundwater. This is a reasonable assumption given the distance of
MW-1 from the source, and the fact that the water table is approximately 40 feet beneath the
surface. Additionally, the water supply wells are upgradient of the former UST basin.

QUALIFIERS
Project: PTSS
Pace Project No.: 92461617
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI -The NELAC Institute.
LABORATORIES
PASI-C Pace Analytical Services - Charlotte
ANALYTE QUALIFIERS
E Analyte concentration exceeded the calibration range. The reported result is estimated.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.

QUALIFIERS
Project: PTSS
Pace Project No.: 92462228
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI -The NELAC Institute.
