B. EXECUTIVE SUMMARY
This report covers the semi-annual period July 2022 through December 2022. The contaminant
levels increased in MW-1: benzene, MTBE, naphthalene, and 1,2 DCE were detected above their
standards, but all are well below their gross contaminant level.

D. SITE HISTORY and CHARACTERIZATION
Ray’s Country Store is a former convenience store that sold petroleum products from an
underground storage tank system. A release occurred from the system and the groundwater was
impacted. The AS/SVE system was shut down on February 1, 2017. This report covers the
period July 2022 through December 2022.
E. SITE ASSESSMENT INFORMATION
1.0 WATER SUPPLY WELL SAMPLING
The Kendrick well is the only water supply well within 1,500 feet of the site, it was not sampled
during this event. The former Ray’s building and Ms. Kendrick’s home were condemned by the
City of Gastonia. The buildings have been locked and Ms. Kendrick lives in a tent on the
property. The water supply well has not been used for several years because the pump is down
and Ms. Kendrick has not had it repaired or replaced. Additionally, there is no power to the
wellhouse – the meter box for the residence has been removed.

2.0 MONITOR WELL SAMPLING
2.1 Well Abandonment
The following wells have been abandoned due to construction: MW – 2, 7, 8, 9, 10, 11, 12, 13,
14 and 15. A monitor well from the adjacent site has been utilized for MW-2, it is within ten feet
of the original MW-2’s location and it is designated MW-2R.
2.2 Sampled Wells and Protocol
DEQ requires that the following wells be sampled: MWs 1-3-5. The wells were sampled with
new, disposable bailers after first gauging the wells and then purging three well casing volumes.
The samples were placed in laboratory provided vials, fixed with a chain of custody, and placed
on ice for shipment between the field, office, and laboratory. They were collected January 5,
2023 and immediately delivered to PACE Analytical.
2.3 Sampling Results
The following four compounds were detected above their standards in MW-1: benzene, MTBE,
naphthalene, and 1,2 DCE. Benzene was detected at its standard in MW-3. All are well below
their gross contaminant levels. There have now been twenty-eight consecutive sampling events
with all contaminants below their gross contaminant level. This is due to the overall contaminant
reductions in MWs – 1 & 3, both of which initially contained free product. A review of the
sampling results follows:
MW-1: benzene (20 ppb), MTBE (27 ppb), naphthalene (7 ppb), and 1,2 DCE (2 ppb)
all four > standard, but < GCL;
MW-3: benzene: 1 ppb, = standard, but < GCL; and
MW-5: non-detect.
A comparison with the last sampling event follows:
MW-1: BTEX/MTBE increase,
MW-3: TEX increase, and
MW-5: BTEX/MTBE remain non-detect.
Natural attenuation is effective as the contaminant levels have decreased to minor levels, with
all compounds well below their gross contaminant level. The results are presented in Table B-4,
Table 1 is a historical summary of the sampling results, linear and log time/concentration graphs
are attached, and the laboratory analysis is attached. Individual BTEX/MTBE maps are
attached; two maps are presented for each compound, a large scale map shows the entire area,
and the other focuses on the site property.

I. CONCLUSIONS
Compound levels increased in MWs 1 & 3, but they remain extremely low; MW-5 remained
non-detect. Four compounds were detected above their standard but all four are well below their
gross contaminant level. Natural attenuation has been effective in reducing the contaminants to
minor levels,

QUALIFIERS
Pace Project No.:
Project:

RAYS COUNTRY STORE
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.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
