1 BACKGROUND

The site is located at 6530 Fairview Road, Charlotte, Mecklenburg County, North Carolina,
southwest of the intersection of Fairview Road and Sharon Road (Figure 1). The site is identified
by the Mecklenburg County, NC Tax Assessor’s Office as Parcel ID Number (PIN) 17901167 and
consists of 0.415-acres of developed commercial land. The site is the location of former
ExxonMobil (Exxon) facility #40563, listed by the North Carolina Department of Environmental
Quality (NCDEQ) as Facility Number 00-0-0000014845, which reportedly operated from 1965 to
1998. The site was then redeveloped as an expansion of the southern adjoining Harper’s
Restaurant – Charlotte, which reportedly remained in operation until 2010. The site is currently
owned by C/O Foundry Commercial and BLT I, LLC., and is associated with a Verizon Wireless
cell phone retail store and paved asphalt parking lot areas.

Exxon reportedly operated the site as an automotive repair service operation as early as 1965. In
1970, four (4) underground storage tanks (USTs) were reportedly installed to service two to four
fuel pump islands for retail gasoline service operations. The tanks included two (2) 8,000-gallon
gasoline USTs, one (1) 6,000-gallon gasoline UST, and one (1) 1,000-gallon new/used oil UST.
These USTs were reportedly removed on April 30, 1988, when Exxon redeveloped the site to
construct a new retail automotive service station. An upgraded UST system was installed at the
time, consisting of one (1) 12,000-gallon regular unleaded gasoline UST, one (1) 10,000-gallon
middle-grade unleaded gasoline UST, and one (1) 10,000-gallon premium unleaded gasoline
UST.

Free product was discovered during the excavation activities of the new UST bed in 1988. In
November 1990, the USTs and product lines were reportedly tested due to a product inventory
variation. Results indicated a leak of the product line associated with the 12,000-gallon regular
unleaded gasoline UST. A petroleum hydrocarbon release incident was reported on December 3,
1990, following the discovery of free product in one of the UST field observation wells. The
incident was documented as UST Incident Number 9122. The site was divested by Exxon and
redeveloped in 1998, and the tanks were reportedly removed on April 16, 1998.

Kleinfelder took over groundwater monitoring responsibilities from the previous consultant, Arcadis
G&M of North Carolina, Inc. (Arcadis) in November 2021. The tables from the 2020 Annual
Corrective Action Plan Monitoring Report from Arcadis are provided in Appendix B. The NCDEQ
Risk Classification for the site is “Intermediate” due to the reported presence of dissolved-phase
constituents at concentrations exceeding applicable NCDEQ Gross Contaminant Level
Standards (NC GCL Standards). Therefore, concentrations of chemicals of concern (COCs) in
groundwater are being compared to the NC GCL Standards.

Adjoining properties include commercial retail buildings associated with Burger King, FedEx
Office Print & Ship Center, Vintage Nail Bar, and Jimmy Johns to the east beyond Sharon Road;
Harper’s Restaurant - Charlotte abuts the site to the south, beyond which a paved asphalt parking
lot and commercial retail properties are apparent; a paved asphalt parking area to the west,
beyond which is a Circle K retail gasoline fueling station and convenience store; and another
Circle K retail gasoline fueling station and convenience store to the north beyond Fairview Road.
The surrounding area is occupied by a mix of residential and commercial land uses.

1.1 FREE PRODUCT HISTORY
Approximately 50 to 75 gallons of free product was reportedly removed from the site by Exxon in
1988 as part of the installation of a new gasoline UST system. Free product was detected at the
site in five (5) groundwater monitoring events between October 10, 2008 and November 23, 2009
within groundwater monitoring well MW-1 at a maximum apparent thickness of 0.53-ft. Free
product was detected at the site in one (1) groundwater monitoring event on October 10, 2008
within groundwater monitoring well MW-2R at a thickness of 0.04-ft. Free product has not been
reported within the sampled groundwater monitoring wells since November 23, 2009, and was
historically recovered by manual bailing and periodic aggressive fluid vapor recovery (AFVR)
events.

1.2 SITE REMEDIATION HISTORY
Approximately 50 to 75 gallons of free product and approximately 30 tons of petroleum-impacted
soil were reportedly removed from the site by Exxon in 1988 as part of the installation of a new
gasoline UST system. Based on a review of previous environmental reports, site remediation
activities began in 1991. Between January 1991 and May 1996, Environmental Resources
Management – Southeast, Inc. (ERM) reportedly conducted a series of site investigations and
assessments. ERM constructed three (3) 2-inch diameter groundwater monitoring wells, MW-1,

20233796.004A /RAL23R158411 Page 3 of 11 November 6, 2023

KLEINFELDER 3200 Gateway Centre Blvd., Suite 100, Morrisville, NC 27560 p | 919.755.5011 f | 919.755.1414

MW-2, MW-3, on February 14, 1991, to total depths of 20, 16, and 16 feet below ground surface
(ft bgs), respectively. Two (2) additional 2-inch diameter groundwater monitoring wells, MW-4
and MW-5, were constructed on August 22, 1991, to total depths of 17 ft bgs. ERM operated a
vacuum vaporizing well using an Unterdruck-Verdampfer-Brudden Technology (UVB) in-situ
circulation/air stripping soil and groundwater remediation system from November 1994 through
June 1996. Two UVB wells, UVB-S and UVB-D, were installed on September 12, 1994, to a total
depth of 16 ft bgs and on October 5, 1994, to a total depth of 30.42 ft bgs, respectively. One (1)
2-inch diameter groundwater monitoring well, DW-6, was installed on February 7, 1996, to a total
depth of 46 ft bgs.

As part of site closure activities in April 1998, approximately 645.32 tons of petroleum impacted
soil was reportedly removed from the site. Arcadis assumed groundwater monitoring around this
time and conducted at least ten (10) 8-hour AFVR events at the site between September 18,
1998, and July 26, 2011. Monitoring wells MW-2 and MW-5 were abandoned and replaced with
4-inch diameter monitoring wells MW-2R and MW-5R on October 17, 2003, to total depths of 30
ft bgs. Two (2) 2-inch diameter groundwater monitoring wells, MW-6 and MW-7 were installed
on August 17, 2012, to a total depth of 21 ft bgs and on August 16, 2012, to a total depth of 23
ft bgs, respectively. Injection wells IW-1 and IW-2 were installed on July 5, 2013, and were
injected with 1,312 gallons of sodium persulfate, ferrous sulfate, and heptahydrate/citric acid
mixture between December 9 and 12, 2013. Arcadis conducted groundwater natural attenuation
and annual groundwater monitoring from September 1999 to September 2020. Kleinfelder took
over groundwater monitoring responsibilities from the previous consultant, Arcadis G&M of North
Carolina, Inc. (Arcadis) in November 2021.

2 PURPOSE

This report details the results of the September 5, 2023, groundwater sampling event completed
by Kleinfelder. Groundwater samples were collected on-site from four (4) onsite monitoring wells
and water levels were gauged from six (6) onsite monitoring wells. Four (4) monitoring wells,
MW-1, MW-3, MW-4, and DW-6 could not be located at the time of site sampling.

3 METHODS

3.1 MONITORING WELL SAMPLING
A groundwater monitoring event was conducted on September 5, 2023, which included sampling
four (4) onsite monitoring wells and water levels were gauged from six (6) onsite monitoring
wells. Four (4) monitoring wells, MW-1, MW-3, MW-4, and DW-6 could not be located at the time
of site sampling.

Upon arrival at the site, each of the groundwater monitoring wells to be sampled was opened and
allowed to equilibrate to atmospheric conditions. Static water levels were obtained from the
monitoring wells using a decontaminated water level meter. The locations of the monitoring wells
are shown on Figure 2. The monitoring wells were purged of approximately three (3) well volumes
of groundwater or until dry. Groundwater samples were collected using a disposable bailer. The
samples were placed into laboratory-provided sampling vials, labeled, and maintained on ice and
shipped via FedEx™ to Eurofins Lancaster Laboratories Env., LLC in Lancaster, Pennsylvania.
The samples were analyzed for volatile organic compounds (VOCs) by EPA Method 6200B. A
Chain-of-Custody document was utilized throughout the collection and transportation process and
is included with the laboratory report in Appendix A.

4 RESULTS

4.1 GROUNDWATER FLOW DIRECTION
Potentiometric data collected from monitoring wells on September 5, 2023, were used to
generate a contour plot for the shallow zone. Data presented in Table 2 summarizes the current
groundwater elevations at each monitoring well. Water levels measured during the September
2023 sampling event were an average of 0.91 feet higher than those measured in September
2022. Groundwater flow in the shallow zone is generally trending toward the North-Northwest
(Figure 3) with an average horizontal gradient of 0.04 ft/ft. The vertical gradient could not be
calculated since the top of casing elevation for paired monitoring have not been measured.

4.2 MONITORING WELL SAMPLING RESULTS
Analytical results for the latest groundwater samples, which were collected on September 5,
2023, are summarized in Table 1. Groundwater samples were collected from four (4) onsite
monitoring wells and water levels were gauged from six (6) onsite monitoring wells. Four (4)
monitoring wells, MW-1, MW-3, MW-4, and DW-6 could not be located at the time of site
sampling. A map of selected petroleum hydrocarbon constituent concentrations is included as
Figure 3. All groundwater samples were analyzed via EPA Method 6200B.

The following is a summary of the analytical results from the September 5, 2023 sampling that
exceeded the NC 2L Standard:

 Monitoring well MW-2R: Concentrations exceeded the 2L Standard for toluene (1,500
µg/L); ethylbenzene (1,400 µg/L); total xylenes (3,700 µg/L); methyl tert-butyl ether
(MTBE; 170 µg/L); diisopropyl ether (; 710 µg/L); naphthalene (440 F1 µg/L); 1,2,4-
trimethylbenzene (860 F1 µg/L); n-propylbenzene (91 µg/L).

 Monitoring well MW-5R: Concentrations exceeded the 2L Standard for toluene (5,200
µg/L); ethylbenzene (2,500 µg/L); total xylenes (11,000 µg/L); MTBE (210 µg/L);
diisopropyl ether (1,500 µg/L); naphthalene (1,100 µg/L); 1,2-dichloroethane (83 µg/L);
isopropylbenzene (75 µg/L); n-propylbenzene (220 µg/L ); styrene (150 µg/L );1,2,4-
trimethylbenzene (1,700 µg/L); 1,2,5-trimethylbenzene (590 µg/L).

KLEINFELDER 3200 Gateway Centre Blvd., Suite 100, Morrisville, NC 27560 p | 919.755.5011 f | 919.755.1414

 Monitoring well MW-6: Concentrations exceeded the 2L Standard for toluene (12,000
µg/L); ethylbenzene (2,200 µg/L); total xylenes (10,000 µg/L); MTBE (330 µg/L);
diisopropyl (1,400 µg/L); naphthalene (700 µg/L); 1,2-dichloroethane (140 µg/L); n-
propylbenzene (180 µg/L); 1,2,4-trimethylbenzene (1,500 µg/L).

 Monitoring well MW-7: Concentrations exceeded the 2L Standard for benzene (2,800
µg/L); toluene (1,200 µg/L); ethylbenzene (1,100 µg/L); total xylenes (2,800 µg/L); MTBE
(240 µg/L); diisopropyl ether (1,000 µg/L); naphthalene (290 µg/L); 1,2-dichloroethane
(25 µg/L); 1,2,4-trimethylbenzene (450 µg/L); n-propylbenzene (92 µg/L).

The following is a summary of the analytical results from the September 5, 2023 sampling that
exceeded the GCLs:

 Monitoring well MW-2R: The benzene concentration exceeded the GCL of 5,000 µg/L
(7,200 µg/L).
 Monitoring well MW-5R: The benzene concentration exceeded the GCL of 5,000 µg/L
(7,800 µg/L).
 Monitoring well MW-6: The benzene concentration exceeded the GCL of 5,000 µg/L
(11,000 µg/L).

The concentrations listed above are higher than those detected during the September 2022
monitoring event. These increases are likely related to the significant rise in groundwater levels
across the site.

5 CONCLUSIONS AND RECOMMENDATIONS

This report details the results of the September 5, 2023, groundwater sampling event conducted
by Kleinfelder. Groundwater samples were collected from four (4) onsite monitoring wells and
water levels were gauged from six (6) onsite monitoring wells. Four (4) monitoring wells, MW-1,
MW-3, MW-4, and DW-6 could not be located at the time of site sampling.

Groundwater levels are on average 0.91 feet higher than they were during the September 2022
monitoring event. Based on current and historical groundwater elevation data, the shallow
groundwater flow is generally to the north-northwest.

The concentrations are higher than those detected during the September 2022 monitoring event.
These increases are likely related to the significant rise in groundwater levels across the site.

The down-gradient extent of groundwater impact is not defined.

The site should be eligible for closure once all COC concentrations are below their applicable NC
GCL Standards for two consecutive monitoring events.

6 LIMITATIONS

Kleinfelder offers various levels of investigative and engineering services to suit the varying needs
of different clients. It should be recognized that definition and evaluation of geologic and
environmental conditions are a difficult and inexact science. Judgments leading to conclusions
and recommendations are generally made with incomplete knowledge of the subsurface
conditions present due to the limitations of data from field studies. Although risk can never be
eliminated, more detailed and extensive studies yield more information, which may help
understand and manage the level of risk. Since detailed study and analysis involves greater
expense, our clients participate in determining levels of service that provide adequate information
for their purposes at acceptable levels of risk.

The information included on graphic representations in the Annual Corrective Action Plan
Monitoring Report has been compiled from a variety of sources and is subject to change without

Job Notes
This report may not be reproduced except in full, and with written approval from the laboratory. The results relate only to the
samples tested. For questions please contact the Project Manager at the e-mail address or telephone number listed on this
page.
Analytical test results meet all requirements of the associated regulatory program (i.e., NELAC (TNI), DoD, and ISO 17025)
unless otherwise noted under the individual analysis.

Compliance Statement
Analytical test results meet all requirements of the associated regulatory program (e.g., NELAC (TNI), DoD, and ISO 17025)
unless otherwise noted under the individual analysis. Data qualifiers are applied to note exceptions. Noncompliant quality
control (QC) is further explained in narrative comments.
· QC results that exceed the upper limits and are associated with non-detect samples are qualified but further narration is not
required since the bias is high and does not change a non-detect result. Further narration is also not required with QC blank
detection when the associated sample concentration is non-detect or more than ten times the level in the blank.
· Matrix QC may not be reported if insufficient sample or site-specific QC samples were not submitted. In these situations, to
demonstrate precision and accuracy at a batch level, a LCS/LCSD is performed, unless otherwise specified in the method.
· Surrogate and/or isotope dilution analyte recoveries (if applicable) which are outside of the QC window are confirmed
unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g. SDWA, NPDES) must comply with the associated agency requirements/permits.
Measurement uncertainty values, as applicable, are available upon request.
Test results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological
analysis is the collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved,
the test results will be meaningless. If you have questions regarding the proper techniques of collecting samples, please
contact us. We cannot be held responsible for sample integrity, however, unless sampling has been performed by a member
of our staff. Times are local to the area of activity. Parameters listed in the 40 CFR Part 136 Table II as "analyze
immediately" and tested in the laboratory are not performed within 15 minutes of collection.
This report shall not be reproduced except in full, without the written approval of the laboratory.
WARRANTY AND LIMITS OF LIABILITY - In accepting analytical work, we warrant the accuracy of test results for the
sample as submitted. The foregoing express warranty is exclusive and is given in lieu of all other warranties, expressed or
implied, except as otherwise agreed. We disclaim any other warranties, expressed or implied, including a warranty of fitness
for particular purpose and warranty of merchantability. In no event shall Eurofins Lancaster Laboratories Environmental, LLC
be liable for indirect, special, consequential, or incidental damages including, but not limited to, damages for loss of profit or
goodwill regardless of (A) the negligence (either sole or concurrent) of Eurofins Lancaster Laboratories Environmental and
(B) whether Eurofins Lancaster Laboratories Environmental has been informed of the possibility of such damages. We
accept no legal responsibility for the purposes for which the client uses the test results. Except as otherwise agreed, no
purchase order or other order for work shall be accepted by Eurofins Lancaster Laboratories Environmental which includes
any conditions that vary from the Standard Terms and Conditions, and Eurofins Lancaster Laboratories Environmental
hereby objects to any conflicting terms contained in any acceptance or order submitted by client.
