Monitoring Report May 22, 2019
(Former) SERVCO No. 00311 Incident No. 27502
Concord, North Carolina ECEA No. 23056
PROJECT SUMMARY
Groundwater quality samples were collected from nine monitor wells on May 7, 2019, and
laboratory analyzed for volatile organics by EPA Method 6200B. It is ECEA's standard
operating procedure not to gauge monitoring wells with an oil -water interface probe prior to
sampling if said well has not historically shown free product. Static water levels were collected
with a decontaminated water level indicator at locations where free product has not previously
been encountered.
The results of the laboratory data indicate that the groundwater samples collected from
monitoring wells MW-8, MW-9 and MW-10R were above NCAC 2L standards for benzene
and that samples collected from monitoring well MW-1 OR exceeded the NCAC 2B standard
for toluene. The laboratory analysis further indicates NCAC 2L standards for ethylbenzene
and total xylenes were exceeded in the groundwater sample collected from MW-1OR and for
naphthalene in the groundwater samples collected from MW-8 and MW-1 OR. MTBE exceeded
NCAC 2L standards in the groundwater samples collected from MW-9; and PCE exceeded
the NCAC 2L standard in samples collected from MW-2, MW-4, MW-5, MW-7 and MW-9.
None of the groundwater samples collected indicated any constituents exceeding Gross
Contamination Levels (GCLs). No free product was measured in the gauged monitoring wells
during the May 2019 sampling event.
■ Review of the current liquid level data indicates that the predominant groundwater flow at the
site is in a northeasterly direction.
Based on receptor surveys completed by Excel Civil & Environmental Associates (ECEA),
there is one water supply well utilized for irrigation purposes only and located approximately
170 feet upgradient of the release source area. A review of the USGS topographic map
indicates the closest surface water body appears to be an unnamed tributary of Three Mile
Branch located approximately 500 feet north of the subject property. It appears the surface
water is classified as class "C" surface water. Based on the presence of the irrigation well
located within 250 feet of the source area, the site is ranked as a "High" risk site.
■ ECEA submitted a right of entry request to close the irrigation well at Central United Church
on March 18, 2019. Mr. Gary Shue responded on March 21, 2019 that they were unwilling to
allow the well to be abandoned.
The soil and groundwater remediation system, consisting of a soil vapor extraction and air
sparge system was started on June 28, 2010. The system was operational after belts were
installed during the July and August site visits. Based on the TA dated September 13, 2018
ECEA shut the system down on September 27, 2018. The system was off during the May
2019 sampling event.
PLUME STABILITY EVALUATION
ECEA conducted a Mann -Kendall constituent trend analysis (Appendix D) which relies on
three statistical metrics, an "S" statistic which indicates whether concentration trend vs. time
is generally decreasing or increasing; a confidence factor (CF) which modifies the S statistic
to indicate the degree of confidence in the trend result; and a coefficient of variation (COV) to
distinguish describe the variability in the data set. The analysis included an evaluation of both
the overall reductions in the areal extent and plume length for constituents of concern as well

Monitoring Report May 22, 2019

Concord, North Carolina ECEA No. 23056
as an evaluation of the stability of the plume constituent concentrations for monitor wells in
the core and leading edge of the plume.
■ The results of the concentrations evaluation for benzene (MW-1, MW-2, MW-5, MW-8, MW-9
and MW-1 OR), for MTBE (MW-1, MW-2, MW-5, MW-9, MW-1 OR and MW-12), for naphthalene
(MW-8, MW-9, and MW-1 OR), and for toluene, ethylbenzene, and xylenes (MW-8 and MW-
10R) indicated the following:
■ Benzene, MTBE, toluene, and total xylenes concentration trends for all wells evaluated
continue to indicate decreasing trendlines;
■ Naphthalene concentration trends for MW-8 and MW-9 continue to indicate
decreasing trendlines and for MW-1 OR are no trend; and
■ Ethylbenzene concentration trends for MW-8 continue to indicate decreasing
trendlines and for MW-1 OR are stable.
■ A review of the results indicates a consistent and continued reduction in the constituents of
concern with no significant rebound after active system shutdown.
■ Based on a review of previous groundwater modeling and historical concentration trends at
the site, the surface water body does not appear to be threatened at this time.
RECEPTOR SURVEY
An updated receptor survey was conducted by ECEA at the above referenced site.
During the 2019 survey, forty-seven (47) Request for Water Supply Information surveys
were issued to all property owners/occupants located within the source area. Nineteen
(19) of the surveys were returned with more information pertaining to well use at each
property. As part of the receptor survey update, ECEA also conducted a receptor survey
by vehicular reconnaissance within approximately 1,500 feet of the source area.
Based on the receptor survey completed by ECEA, there is one water supply well utilized
for irrigation purposes only and located approximately 170 feet upgradient of the release
source area. A review of the USGS topographic map indicates the closest surface water
body appears to be an unnamed tributary of Three Mile Branch located approximately
500 feet north of the subject property. It appears the surface water is classified as class
"C" surface water. Based on the presence of the irrigation well located within 250 feet of
the source area, the site is ranked as a "High" risk site.
Copies of the returned well surveys are provided in Appendix E.

(Former) SERVCO No. 00311 Incident No. 27502
Concord, North Carolina ECEA No. 23056
CONCLUSIONS & RECOMMENDATIONS
■ In summary, current laboratory analytical data indicates that overall dissolved phase
hydrocarbon constituents (primarily BTEX and MTBE) continues to occur at the site and are
decreasing with some seasonal fluctuations. Remaining constituent levels exceed NCAC 2L
standards at multiple locations for various constituents and at one monitor well exceed NCAC
2B standards (benzene and toluene).
■ Groundwater flow direction in the shallow aquifer is consistently in the northeasterly direction;
the irrigation well is located upgradient of the source area and does not appear to be
threatened at this time.
■ To evaluate a risk to surface water, ECEA previously completed a groundwater flow model on
constituents benzene and toluene that exceeded applicable NCAC 2B standards. The results
of the analysis indicated that hydrocarbon constituents would be degraded before impact to
the surface water body.
■ At this time, based on the information in this report, we recommend incident closure through
a Notice of Residual Petroleum and issuance of a No Further Action for the incident.

PROJECT INFORMATION
PRIMARY CONSULTANT: Excel Civil & Environmental Associates, PLLC
PROJECT MANAGER: Mike Stanforth
SERVCO CONTACT: Robert Gresham
SITE HISTORY: All five regulated UST's were removed as part of one excavation
during the closure activities in April 2003. A review of the results
reportedly indicated soil -sampling results with elevated levels of
petroleum hydrocarbons above the applicable NCDEQ
standards. A Limited Site Assessment Report was completed in
September 2003, which identified contaminated soils and
groundwater beneath the site with one water supply well utilized
for irrigation purposes located approximately 200 feet
upgradient of the site. The nearest surface water body is an
unnamed tributary of Three Mile Branch, which is located
approximately 500-feet north of the site. A Comprehensive Site
Assessment Report was completed in July 2004, further defining
the extent of soils and groundwater contamination.
ECEA completed a Corrective Action Plan for the property in
February 2009, which recommended the utilization of air
sparging & soil vapor extraction (SVE) for remediation of
underlying soils & groundwater at the site. ECEA contracted
Onion Equipment Company and Harvest Environmental
Services, Incorporated for the installation and startup of the SVE
and air sparge remediation system, comprised of nine air sparge
points and twelve SVE wells. The remediation system was
started up in June, 2010 and shut down in September 2018.
GENERAL GEOLOGY:
Geologically, the subject site is located in the Central Piedmont
Physiographic Province. The 1985 USGS Geologic Map of North
Carolina indicates this area of the Central Piedmont consists of
metamorphosed quartz diorite, which is foliated to massive. The
soils were identified as silts and clays with heavy weathered rock
encountered at 45-fbgl.

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
Guide to Reading and Understanding Your Laboratory Report
ONE LAB. NATIONWIDE.
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.
Abbreviations and Definitions
CP
IP
FTC
MDL
Method Detection Limit.
RDL
Reported Detection Limit.
FSS
Rec.
Recovery.
RPD
Relative Percent Difference.
SDG
Sample Delivery Group.
[Cn]
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
detected in all environmental media.
FSr
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
Fc
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
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
FAI
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
FSC
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.
