RE: Letter Report Bradley Food Store US Highway 70 East Nebo, McDowell County, North Carolina NCDEQ Incident No.: 23994
NCDEQ Contract No. N17006 ECS Project No. 49:1203-C
Dear Ms. Ghiold:
As authorized by your acceptance of ECS Southeast, LLP’s (ECS) Task Authorization Request
No. 3 dated November 12, 2019, ECS has prepared a Letter Report for the above referenced site. This report includes a description of the work performed, the results obtained, and our conclusions and recommendations.
PROJECT UNDERSTANDING
The subject site is known as the Former Bradley Food Store and is located on US Highway 70 East, northwest of the intersection with Sherwood Forest Drive, in Nebo, McDowell County, North Carolina (Figures 1 and 2). The property is a vacant, former convenience store/gasoline station which was identified as a potential source of petroleum compounds identified in nearby water supply wells.
FIELD ACTIVITIES
Monitoring Well Sampling
On January 8, 2020, ECS personnel mobilized to the site to gauge monitoring well MW-1using a
decontaminated electronic water level meter. The locations of the monitoring well is shown on
Figure 3. The depth to water in monitoring well MW-1 on January 8, 2020, was 53.51 feet below the top-of-casing. A summary of the current and historic groundwater depth measurements are included on Table 1.
Following the gauging of the well, ECS personnel collected a groundwater sample from monitoring well MW-1. Prior to sampling, the well was purged using a new disposable polyethylene bailer and new length of nylon cord. The well was developed/purged by evacuating a minimum of three well volumes using the bailer and cord. The well was developed/purged to
remove sand, silt and other fine sediments and to promote communication between the surrounding formation and the sand pack surrounding the well’s screened interval. After purging was completed, the sampler poured the groundwater sample from the bailer into laboratory

prepared containers. Each container was labeled and placed in a cooler containing ice to maintain the samples at approximately four degrees Celsius. The sample containers were then submitted to Pace Analytical Services, LLC (Pace) in Huntersville, North Carolina to be analyzed for volatile
organic compounds (VOCs) using Standard Method 6200B. A Chain of Custody Record was maintained and is attached. A copy of the sample collection field notes are also attached.
Water Supply Well Sampling
ECS also collected samples from water supply wells WSW-A, WSW-B, and WSW-C on January
8, 2020. The locations of the water supply wells are indicated on Figure 4. Information regarding the water supply wells is included in Table 2. The water supply wells and associated piping were purged for approximately 15 minutes each prior to sample collection. The samples were collected directly into laboratory prepared containers. Each container was labeled and placed in a cooler containing ice to maintain the samples at approximately four degrees Celsius. The sample containers were then submitted to Pace to be analyzed for VOCs using Standard Method 6200B. A Chain of Custody Record was maintained and is attached. A copy of the sample collection field notes are also attached.
RESULTS
Review of the laboratory analytical report did not indicate any compounds in any of the samples collected at concentrations greater than the laboratory method reporting limit. A summary of current and historical sample analytical results is presented in Table 3. A copy of the laboratory
analytical report is attached.
CONCLUSIONS AND RECOMMENDATIONS
Compound concentrations have not been indicated in samples collected from monitoring well MW-1 since June 2012. In addition, compound concentrations have not been indicated in water supply
wells WSW-A, WSW-B, and WSW-C since July 2011, July 2015, and July 2011, respectively. As such, ECS recommends granting the site a status of No Further Action.

QUALIFIERS
Pace Project No.:
Project:
92459849
49-1203C
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 andbias 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 isa 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 foreach 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.
