NCDEQ Incident No. 2067
UST No. RA-494

Dear Ms. Blalock:

ATC Associates of North Carolina, P.C. (ATC) is pleased to submit the results of an aggressive fluid vapor
recovery (AFVR) event conducted on June 20, 2023, at the Faisons Community property located at the
intersection of Galatia Road and US Highway 158, Conway, North Carolina. The AFVR event was
performed based on an May 15, 2023, Task Authorization (TA-01) by the Trust Fund Branch of the
Underground Storage Tank (UST) Section, Division of Waste Management (DWM), North Carolina
Department of Environmental Quality (NCDEQ). The work is being performed as part of State Lead Contract
#N70522-B between NCDEQ and ATC.

The property is associated with one parcel that is developed with a residential building and the other that is
developed with a commercial building that appears to be used as a storage unit by the property owner. A
site topographic map is included as Figure 1. The site formerly utilized one 400-gallon UST, one 14,000-
gallon UST, and one 10,000-gallon UST, all of unknown contents and were removed in 2009. Eight Type II
monitoring wells (MW-1 through MW-8) are associated with the site. A site map depicting pertinent site
features is included as Figure 2. Based on ATC’s findings, it appears there are nine water supply wells
within 1,000 feet of the source area. Of the nine wells, six are inactive, one is used for drinking purposes,
and two are used for irrigation purposes, none of the water supply wells are within 250 feet of the source
area. Municipal water is available to all properties within the area. Water supply well ownership information
is included in Table 1 and the water supply well locations are depicted on the Potential Receptor Map
included as Figure 3.

On June 20, 2023, Eastern Environmental Management, LLC (Eastern) was subcontracted to perform an
eight-hour aggressive fluid vapor recovery (AFVR) event using MW-8 as an extraction point. Light non-
aqueous phase liquid (LNAPL) was previously detected in well MW-8 during the January 13, 2023 sampling
event. Prior to and following the event, ATC gauged MW-8 for liquid levels. LNAPL was detected at a
thickness of 0.26 feet prior to the AFVR event and was not detected following the event. Monitoring well
construction details and groundwater elevation data are included as Table 2 and 3, respectively. The AFVR
event began at 08:00 am and ended at 04:00 pm and generated approximately 675 gallons of petroleum
impacted groundwater from well MW-8. The AFVR calculations are included as Table 4. Field notes for the
field activities are included in Appendix A. The waste disposal manifest from the event is provided in
Appendix B. Based on calculated recovery volumes for the AFVR event, an estimated 3.39 gallons (0.54
pounds) of petroleum were recovered as vapors.

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.
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.
Q Sample was prepared and/or analyzed past holding time as defined in the method. Concentrations should be
considered minimum values.
