Introduction
This report presents the results of the December 2023 water supply well monitoring event conducted for the seven water supply wells surrounding the Four Point 76 located at 1702 Hickory
Grove Road in Belmont, Gaston County, North Carolina. NCDEQ requested WSW-1 be dropped from the sampling list and sample water supply wells WSW-2, WSW-7, WSW-8, WSW-9, WSW-17, WSW-18, and WSW-19.
Field Activities

The seven water supply wells surrounding Four Point 76 were sampled on December 21, 2023.
Each well was sampled following a purge of approximately 20 minutes to allow the well to equalize and clean out each pressure tank. Each water sample was transferred directly from the spigot to the appropriate sample container provided by the laboratory. The samples were stored on ice and delivered to Pace Analytical. All samples were submitted for laboratory analysis of
Volatile Organics (VOCs) by method 6200B. A copy of the laboratory deliverable package is included in the Appendix of this report. Sampling Results
Groundwater
Laboratory analysis of wells WSW-2, WSW-7, WSW-8, WSW-9, WSW-17, WSW-18, and
WSW-19 did not detect any compounds above the NCAC 2L groundwater standards.
Water Supply Well Information
Currently, there are 68 water supply wells located within 1,000 feet of the site. This report represents the sampling and analysis of the seven water supply wells closest to the Site.
Groundwater Flow Direction
During the Comprehensive Site Assessment (CSA), the groundwater flow direction at the site was determined to be to the east-southeast.
Conclusions and Recommendations

None of the seven water supply wells contained any compounds exceeding the NCAC 2L groundwater standards. Singleton Environmental recommends forwarding this report to the NCDEQ Toxicologist for review.

QUALIFIERS
Pace Project No.:
Project:
92705311
Four Point 76 12/21
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 EPAMethod 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.
