1 BACKGROUND

The site is located at 2701 The Plaza, Charlotte, Mecklenburg County, North Carolina (Figure 1).
The site is identified by the Mecklenburg County, NC Tax Assessor’s Office as
Parcel ID Number (PIN) 08314217 and consists of 1.533 acres of developed commercial
land associated with a retail gasoline filling station and convenience store.

Adjoining properties include retail buildings to the east, beyond Brook Road; residential land to
the north and south, beyond Woodside Avenue and The Plaza Road, respectively; and vacant
commercial land to the west. The surrounding area is occupied by a mix of residential and
commercial land uses.

1.1 FREE PRODUCT HISTORY
Free product was intermittently observed within groundwater monitoring well MW-9 from 2008 to
2013 at a maximum apparent thickness of 1.41 feet.

1.2 SITE REMEDIATION HISTORY
A review of previous reports of the assessment and remedial activities that have occurred at
the site indicates that the Former ExxonMobil (Exxon) Facility #40544 reportedly began operation
as a service station in August 2000. There are two (2) 15,000-gallon fiberglass, gasoline,
underground storage tanks (USTs) located in the southwestern portion of the site. Site
characterization activities were initiated in April 2007, which confirmed subsurface petroleum
impacts to soil and groundwater. Five (5) aggressive fluid vapor recovery (AFVR) events were
conducted utilizing groundwater monitoring well MW-9 as an extraction well from August 2009 to
March 2011. Dissolved-phase chemicals of concern (COCs) remain present in groundwater at
concentrations above applicable NC Administrative Code (NCAC) Title 15A, Subchapter 2L .0202
Groundwater Standards (NC 2L Standards), and benzene remains apparent above the NC Gross
Contamination Limits Standard (NC GCL Standard).

Kleinfelder took over groundwater monitoring responsibilities from the previous consultant, Arcadis
G&M of North Carolina, Inc. (Arcadis) in August 2021.

2 PURPOSE

This report details the results of the November 9, 2022, groundwater sampling event completed
by Kleinfelder. Groundwater samples were collected on-site from a total of three (3) monitoring
wells. A total of six (6) monitoring wells were gauged. One monitoring well, MW-8, could not be
located at the time of site sampling. One injection well, INJ-1, was dry at the time of the sampling
event.

3 METHODS

3.1 MONITORING WELL SAMPLING
A groundwater monitoring event was conducted on November 9, 2022, which included sampling
three (3) on-site monitoring wells. A total of six (6) monitoring wells were gauged. One
monitoring well, MW-8, could not be located at the time of site sampling. One injection well, INJ-
1, was dry at the time of the sampling event.

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 either a peristaltic pump
with disposable polyethylene tubing or a submersible Grundfos pump with disposable
polyethylene tubing. Field measurements of pH, specific conductivity, dissolved oxygen,
oxidation reduction potential and temperature were measured, except where access limitations
prevented some of the measurements. A summary of field attenuation data from the November
2022 sampling event is provided in Table 3. 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 November 9, 2022, were used to
generate a contour plot for the shallow zone. Data presented in Table 1 and Table 2 summarizes
the current groundwater elevations at each monitoring well. Water levels measured during the
November 2022 sampling event were an average of 2.07 feet lower than those measured in
November 2021. Based on current and historical groundwater elevation data, the shallow
groundwater flow is generally to the north with an average horizontal gradient of 0.009 ft/ft.
(Figure 3).

4.2 MONITORING WELL SAMPLING RESULTS
Analytical results for the latest groundwater samples, which were collected on November 9, 2022,
are summarized in Table 1 and Table 2. Groundwater samples were collected from three (3)
on-site monitoring wells MW-4, MW-5, and MW-9. The well locations are depicted on Figure 2
and monitoring well laboratory analytical data are illustrated on Figure 3. The laboratory analytical
report is included as Appendix A. Historic cumulative groundwater monitoring data tables from
Arcadis are included as Appendix B.

Groundwater samples collected from the following three (3) groundwater monitoring wells
exhibited detectable concentrations of constituents above their respective NC 2L Standards:
 Monitoring well MW-4: Benzene (1,600 µg/L); methyl tert-butyl ether (MTBE; 640 µg/L);
naphthalene (70 µg/L).
 Monitoring well MW-5: Benzene (11 µg/L); methyl tert-butyl ether (MTBE; 46 µg/L).
 Monitoring well MW-9: Benzene (8,700 µg/L); toluene (23,000 µg/L); ethylbenzene
(1,900 µg/L); total xylenes (10,000 µg/L); MTBE (1,100 µg/L); naphthalene (310 µg/L);
propylbenzene (150 µg/L); 1,2,4-trimethylbenzene (1,400 µg/L).

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

5 CONCLUSIONS

Groundwater samples were collected from three (3) on-site monitoring wells. A total of six (6)
monitoring wells were gauged. All wells were screened for the presence of standing free product
using an interface probe. One monitoring well, MW-8, could not be located at the time of site
sampling. One injection well, INJ-1, was dry at the time of the sampling event.

Based on current and historical groundwater elevation data, the shallow groundwater flow is
generally to the north.

One (1) constituent concentration in the shallow groundwater zone exceeded their applicable
NC GCL Standard. Benzene was detected at a concentration of 8,700 micrograms per liter (µg/L)
in the groundwater sample collected from monitoring well MW-9, above the applicable NC GCL
Standard of 5,000 µg/L. No other constituent concentrations in the shallow groundwater zone
exceeded their applicable NC GCL Standards.

Kleinfelder recommends continued annual groundwater monitoring until COC concentrations in
all sampled groundwater monitoring wells are below their respective applicable NC 2L Standards
for at least two (2) consecutive groundwater 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 Groundwater Monitoring
Report has been compiled from a variety of sources and is subject to change without notice.

Eurofins Lancaster Laboratories Environment Testing, LLC
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.
