Dear Ms. Beverly:
Excel Civil & Environmental Associates, PLLC (Excel) submits for your review and approval
this Groundwater Sampling Letter Report for the above -referenced facility. As per the
approved scope of work, Excel obtained groundwater samples from monitoring wells MW-
8, MW-9 and MW-10R on November 1, 2019. Laboratory analytical data indicates that
overall dissolved phase hydrocarbon constituents continues to occur at the site and are
decreasing with some seasonal fluctuations. Remaining constituent levels exceed NCAC
2L standards for all three monitoring wells for various constituents and at MW-1OR exceed
NCAC 2B standards for toluene. At this time, we recommend incident closure through a
Notice of Residual Petroleum and issuance of a No Further Action for the incident.
If you have any questions, please contact me.
Sincerely yours,
EXCEL CIVIL & ENVIRONMENTAL ASSOCIATES, PLLC
M.T. Stanforth, P.E.
Principal Engineer
p.c. Bob Gresham — SERVCO, Albemarle, NC

CASE NARRATIVE
ONE LAB. NATIONWIDE.
FP1
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
FTChave
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
FSS
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
ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report
FP1
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,
FTC
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
FSS
MDL
Method Detection Limit.
RDL
Reported Detection Limit.
[Cn]
Rec.
Recovery.
RPD
Relative Percent Difference.
FSr
SDG
Sample Delivery Group.
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
(S)
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
rqC
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.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
Dilution
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
FAI
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.
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
SC
duplicated within these ranges.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
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.
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"
Result
(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.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
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
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
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.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
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.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
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.
J4
The associated batch QC was outside the established quality control range for accuracy.

ACCREDITATIONS & LOCATIONS ONE LAB. NATIONWIDE.
Pace National is the only environmental laboratory accredited/certified to support your work nationwide from one location. One phone call, one point of contact, one laboratory. No other lab is as
accessible or prepared to handle your needs throughout the country. Our capacity and capability from our single location laboratory is comparable to the collective totals of the network
laboratories in our industry. The most significant benefit to our one location design is the design of our laboratory campus. The model is conducive to accelerated productivity, decreasing FP1
turn -around time, and preventing cross contamination, thus protecting sample integrity. Our focus on premium quality and prompt service allows us to be YOUR LAB OF CHOICE.
Not all certifications held by the laboratory are applicable to the results reported in the attached report.
Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace National. Z
