NCDEQ Incident No. 5367
UST No. RA-728

Dear Ms. Blalock:

ATC Associates of North Carolina, P.C. (ATC) is pleased to submit a Letter Report for the groundwater
sampling activities conducted at the site on June 21, 2023. The sampling activities were performed based on a
May 24, 2023, Task Authorization (TA-01) by the Trust Fund Branch of the Underground Storage Tank (UST)
Section, Division of Waste Management, North Carolina Department of Environmental Quality (NCDEQ). The
work is being performed as part of the State Lead Contract #N70522-B between NCDEQ and ATC.

Graham’s Grocery is located at 3957 Eastern Avenue (Old US Highway 64 West) in Rocky Mount, Nash
County, North Carolina. The site is developed with a vacant single-story building. Six monitoring wells (MW-3,
MW-5R, MW-6, MW-8, MW-9, and MW-10) are associated with the site. Two water supply wells (WSW-1 and
WSW-5) are located within 1,000 feet of the site. The onsite water supply well (WSW-1) had previously been
used for drinking purposes, but was found to be inactive when the site was vacated circa September 2021.
Well WSW-5 is an inactive well located 550 feet north of the site. According to the City of Rocky Mount,
municipal water is available to the site; however, excessive municipal tap and acreage fees make water
connection expensive. Water supply well information is included as Table 1. Historical water supply well
analytical data is summarized in Table 2. A site topographic map is included as Figure 1. A site map depicting
pertinent site features is included as Figure 2. Water supply well locations are shown on Figure 3.

ATC personnel conducted a groundwater sampling event on June 21, 2023. During the event, groundwater
levels measurements were collected from MW-8 and MW-10. During the event, monitoring well MW-6 could
not be located. Road widening activities were observed along Eastern Avenue and the well may have been
destroyed. In addition, underground utility work was observed along South Old Carriage Road and MW-9 was
found to be filled in with apparent concrete and was determined to be destroyed. Groundwater levels ranged
from 12.68 feet below ground surface (bgs) in MW-8 to 13.55 feet bgs in MW-10. Monitoring well construction
and groundwater elevation data are summarized in Table 3. The groundwater samples were placed in
laboratory-supplied containers, entered into chain-of-custody control, placed on ice, and shipped to Pace
Analytical in Mount Juliet, Tennessee for analysis by Standard Method 6200B. Field notes from the sampling
event are included as Appendix A. Site photographs of the site and monitoring wells are included in
Appendix B.

Monitoring well MW-8 exhibited concentrations of benzene, toluene, ethylbenzene, total xylenes, naphthalene,
isopropylbenzene, n-propylbenzene, 1,2,4-trimethylbenzene, and 1,3,5-trimethylbenzene above Title 15A
NCAC 02L .0202 Groundwater Quality Standards (2L Standards). No other petroleum constituents were
detected above 2L Standards. No petroleum consituents were detected above the Gross Contamination
Levels. Field parameters collected during the sampling event are shown in Table 4. Current groundwater
analytical data is summarized in Table 5. Historical groundwater analytical data is summarized in Table 6.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.
J3 The associated batch QC was outside the established quality control range for precision.
J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high.
