1.0 INTRODUCTION
Terracon has prepared this Groundwater Monitoring Report on behalf of the North Carolina
Department of Transportation (NCDOT) Roadside Environmental Unit. It presents the findings of
recent field activities conducted by Terracon at the Mt. Pleasant Maintenance Facility (the site),
located at 150 Dutch Road in Mt. Pleasant, Cabarrus County, North Carolina (Figure 1).
1.1 Site Description
The site is located at 150 Dutch Road approximately 650 feet north of its intersection with
NC Highway 73 in Mt. Pleasant, Cabarrus County, North Carolina. The site is bisected by Dutch
Road. Topography at the site slopes gently to the west towards Dutch Buffalo Creek, which is
located along the western property boundary.
The site is currently occupied by the NCDOT Cabarrus County Maintenance Yard. The site is
primarily asphalt -paved with isolated lawn and landscaped areas. Several buildings are located
on the site including various administrative offices, maintenance shops, and storage buildings.
Various NCDOT machinery, vehicles, and equipment are also staged on the site. The
surrounding area is primarily used for agricultural and rural residential purposes. The Cabarrus
Correction Center is located south of the site.
1.2 Site Operational History
The site is currently occupied by the NCDOT Mt. Pleasant Maintenance Yard. Dating back to
1958, 12 underground petroleum storage tanks (USTs) have been maintained at the site. The
USTs have contained gasoline, diesel, kerosene, and waste oil. Nine (9) of the USTs have been
removed from the site, while three (3) remain in -place and are currently active. The following
table provide details on the current and former on -site USTs.

NCDOT Mt. Pleasant Maintenance Yard
December 7, 2018 Terracon Project No. 71177023
1.3 Site Investigation History
The site was first investigated in May 1992 when three (3) monitoring wells were installed
following the removal of USTs 1 through 8 in 1990 and 1991. Additional data regarding the
identification, location, or analytical results associated with these wells was not available in the
NCDEQ incident file associated with the site.
Thirteen (13) monitoring wells (MW-1 through MW-10 and TP-1 through TP-3) were reported to
have been located at the site (ECS, 1997). Groundwater has been estimated to flow to the north.
Petroleum constituent concentrations are known to have historically been identified in monitoring
wells MW-2, MW-4, MW-6, MW-7, MW-8, and MW-9. Free product was historically measured in
monitoring well MW-6 (1.5 inches on November 14, 1996 [ECS, 1997]). Naphthalene was
detected at a concentration of 197 micrograms per liter (µg/L) during the November 22, 1996
sampling event (ECS, 1997).
Residual soil contamination has been reported in the vicinity of USTs 1 and 5 (ECS, 1997). The
most recent investigation occurred in 2005 after the removal of UST 9 (2,000-gallon waste oil
UST).
1.4 Historical Receptor Information
Subsurface utilities consisting of water, sewer, and storm drain lines are present at the site
generally buried at depths up to 3 feet below land surface (bls). Existing on -site buildings are
constructed as slab -on -grade; thus, crawlspaces are not present.
The closest surface water feature is Dutch Buffalo Creek, which extends along the western
property boundary. Seven (7) water supply wells were previously identified within 1,500 feet of
the source area (ECS, 1997). Public water is available to the site and surrounding properties by
the Town of Mt. Pleasant.
1.5 Site Remedial History
Remedial activities at the site have been limited to the removal of USTs and over -excavation of
soils near the USTs. USTs 1 through 8 were removed in 1990 and 1991. Approximately 185
cubic yards of soil was reportedly removed and spread on the site with NCDEQ approval. The
location of the spread soils is unknown. UST 9 was removed in 2005. Excavated soils were not
reported during the removal of UST 9.

1.6 Site Regulatory Status
A September 2018 Notice of Regulatory Requirements (NORR) issued by the NCDEQ indicated
that the site's risk ranking was "High". The NORR stated the following requirements:
sample the existing on -site monitoring wells on a semi-annual basis (May and
November); and
sample water supply wells within 1,000 feet of the site.
The NORR was dated September 13, 2018 and indicated a completed monitoring report
summarizing the requested activities be submitted to the NCDEQ by November 30, 2018.
Terracon submitted a request for an extension to Ms. Trudy Beverly of the NCDEQ — Mooresville
Regional Office. Ms. Beverly granted an extension until December 14, 2018.
1.7 Objectives and Scope of Work
The objective of the scope of work was to monitor the dissolved phase plume conditions and
sample supply wells. This report contains a summary of the following activities and results:
sampling of the existing monitoring well network;
sampling of supply wells within 1,000 feet of the source area; and
recommendations for future site activities.
1.8 Standard of Care
Terracon's services were performed in a manner consistent with generally accepted practices of
the profession undertaken in similar studies in the same geographical area during the same time
period. Terracon makes no warranties, either express or implied, regarding the findings,
conclusions, or recommendations. Please note that Terracon does not warrant the work of
laboratories, regulatory agencies, or other third parties supplying information used in the
preparation of the report. These services were performed in accordance with the scope of work
agreed with you, our client, as reflected in our proposal.
1.9 Additional Scope Limitations
Findings, conclusions, and recommendations resulting from these services are based upon
information derived from the on -site activities and other services performed under this scope of
work; such information is subject to change over time. Subsurface conditions may vary from
those encountered at specific borings or wells or during other surveys, tests, assessments,
investigations, or exploratory services; the data, interpretations, findings, and our

recommendations are based solely upon data obtained at the time and within the scope of these
services.
2.0 RECEPTOR INFORMATION
2.1 Private Water Supply Wells
Terracon conducted a windshield water supply well survey on February 3, 2017 in an attempt to
locate water supply wells within a 1,500-foot radius from the site boundary. During the visual
reconnaissance, properties were assumed to have a water supply well if a wellhead cover was
observed, such as faux rock, concrete block, or ornamental `wishing well' style structures.
Results are summarized on Table 1 and Figure 3.
Terracon identified the following items:
The service area provided by the Town of Mt. Pleasant Water and Sewer Department
includes properties within a 1,500-foot radius of the site.
Visual evidence of four (4) private water supply wells was identified based on the
reconnaissance survey (Figure 3). Two (2) water supply wells were identified within a
1,000-foot radius of the site.
Terracon contacted the Town of Mt. Pleasant Water and Sewer Department in an effort to
determine if developed properties located within a 1,500-foot radius of the site had a water
account. Based on information provided by Ms. Amy Schueneman of the Town of Mt. Pleasant,
the properties located within the 1,500-foot radius to the north and one property to the south of
the site are not connected to municipal water. In total, six properties were identified within a
1,500-foot radius of the source area that could potentially have water supply wells due to being
developed and not having water accounts. Terracon observed visual evidence of water supply
wells on four of these six properties. Property owners were not directly contacted nor were water
supply well questionnaires issued to property owners in the search radius. As such, the use of
each suspected well (potable water or irrigation) was not confirmed.
2.2 Surface Water
Surface water in the vicinity of the site is part of the Yadkin -Pee Dee River Basin. Dutch Buffalo
Creek is located approximately 300 feet to the west of the source area. A pond is also located
approximately 400 feet to the north of the source area. Surface water runoff at the site generally
flows to the west and southwest towards Dutch Buffalo Creek that is located along the west side
of the property. Surface water features are shown on an excerpt from the Mount Pleasant, NC
7.5-Minute Topographic Quadrangle Map, which is depicted on Figure 1.

2.3 Land Use and Places of Public Gathering
Terracon did not identify properties considered places of public gathering within 1,500 feet of the
site. According to the Cabarrus County GIS database, land use within 1,500 feet of the site is
primarily residential and agricultural with some light commercial.
3.0 FIELD ACTIVITIES AND METHODS
Sampling activities were conducted in general accordance with the September 2018 NORR
issued by the NCDEQ. Field activities conducted during the November 2018 field event included
collection of water level measurements, groundwater samples from 10 monitoring wells, and a
groundwater sample from one water supply well. Site wells are shown on Figure 2 and supply
wells are shown on Figure 3.
3.1 Water Supply Well Sampling
Terracon was able to sample water supply well WSW-3 during the November 2018 sampling
event. However, Terracon was unable to collect samples from the other water supply wells
located within 1,000 feet of the site during the November 2018 sampling event. Terracon staff
knocked on the door of these residences and no one answered. Letters requesting permission to
sample the water supply wells were also left on the front door of the residence. Letters
requesting permission to sample the water supply wells were mailed to the property owners via
certified mail and to date, Terracon has not received the signed certified mail green card or a
response from the letter that was left at the residences.
3.2 Site Inspection and Well Network Evaluation
Terracon conducted an inspection of site monitoring wells. Monitoring well construction details
are provided on Table 2. The following summarizes observations:
As mentioned in the previous report, several wells (MW-2, MW-3, MW-4, and TP-3) could
not be located and were likely paved over based on information gathered from
discussions with NCDOT employees at the site office.
Monitoring well MW-6 was not able to be sampled. The well appears to be constructed of
corrugated plastic pipe and the well is not vertical. MW-6 bends at approximately three
feet below grade which prevented the purging and sampling of the well.
MW-4R and MW-6R were installed on November 3, 2017 to replace MW-4 and MW-6.
The majority of the wells were in good condition.
During the November 2018 groundwater sampling event, water level measurements and
groundwater samples were collected from the following nine monitoring wells:

3.3 Water Level Measurements
Irerracon
MW-9
TP-1
TP-2
Water level measurements were collected from accessible site monitoring wells on
November 14, 2018 to estimate the groundwater flow direction and horizontal and vertical
hydraulic gradient. The water levels were measured with an electronic water level probe that was
decontaminated before and after each use. The water level measurements were converted to
water level elevations using existing top -of -casing elevation data for each well (Table 2). The
water level elevations were used to prepare a water level contour map to estimate the shallow
groundwater flow directions at the site, as discussed in Section 4.1 of this report.
3.4 Groundwater Sample Collection
Groundwater samples were collected using a peristaltic pump. Low flow purging and sampling
techniques were used to the extent practical for each well. During purging, the field geochemical
parameters of temperature, pH, conductivity, dissolved oxygen (DO), and oxidation-reduction
potential (ORP) were measured using a handheld YSI 556 multiparameter probe units. Purging
continued until pH and conductivity parameters stabilized. Table 3 summarizes indicator
parameter measurements of temperature, pH, specific conductance, DO, and ORP.
Sampling equipment was thoroughly decontaminated with phosphate -free soap and distilled
water prior to fieldwork and between each well to prevent cross -contamination. New polyethylene
tubing was used during the purging and sampling of each monitoring well. Decontamination
water and purge water was poured on the land surface.
3.5 Sample Analysis
Once collected, the groundwater samples were placed in appropriately labeled containers and
packed on ice pending delivery to Shealy Environmental Services, Inc. (Shealy). Water samples
collected in the field remained in the presence of a project representative until picked up by
Shealy personnel and delivered to the laboratory in West Columbia, South Carolina. A completed
chain -of -custody record was provided with the cooler containing groundwater samples.

December 6, 2018 Terracon Project No. 71177023
The following analytical methods were requested on the chain -of -custody for the wells sampled
in November 2018:
Volatile organic compounds (VOCs) by EPA Method 8260,
Semi -volatile organic compounds (SVOCs) by EPA Method 8270, and
MADEP Methods EPH and VPH.
3.6 Quality Assurance/Quality Control Samples
The quality assurance/quality control (QA/QC) sampling included one field equipment blank, one
trip blank, and one matrix spike/matrix spike duplicate (MS/MSD). QA/QC samples were
submitted to the laboratory for analysis of VOCs by EPA Method 8260.
4.0 RESULTS
Field and laboratory analytical results from the soil and groundwater sampling events conducted
in November 2018 are discussed in detail below. Laboratory analytical reports from Shealy were
reviewed and validated to ensure that they met specific data -quality objectives. Laboratory
analytical results are provided in Appendix A.
4.1 Groundwater Flow System
Water level measurements were collected from the site monitoring wells on November 14, 2018.
The depth -to -water measurements and the converted water level elevations are listed in Table 2.
Depth to water measurements for the shallow wells (10 to 15 feet bls) ranged from approximately
3.11 to 5.48 feet bls.
Water elevations were used to produce a groundwater surface elevation map for the shallow
wells (Figure 4). Based on the water level measurements collected in November 2018, the
groundwater flow direction in the shallow aquifer zone appears directed to the north.
Groundwater flow directions are generally consistent with historical site data. Shallow
groundwater generally has a hydraulic gradient of approximately 0.023.
4.2 Groundwater Analytical Results
The results of analytical and field parameter results from the November 2018 sampling event are
described below. Constituent concentrations in groundwater are presented in Table 4.
Groundwater analytical results for VOCs, SVOCs, EPH, and VPH were compared with their
NCAC groundwater quality 2L standards (2L standard).

December 6, 2018 Terracon Project No. 71177023
4.2.1 Monitoring Well Network (November 2018)
Seven of the 10 sampled monitoring wells had dectatable concentrations of petroleum
compounds. C11-C22 aromatics were detected at a concentration above the 2L Standards in
MW-6R. Compounds were not detected above 2L Standards in the remaining nine monitoring
wells sampled.
4.3 Evaluation for Vapor Intrusion
Based on the Interstate Technology and Regulatory Council (ITRC) Petroleum Vapor Intrusion
(PVI) guidance, additional evaluation of the PVI pathway for the dissolved -phase plume is not
warranted. The on -site buildings are not likely at a potential risk for PVI based on the observed
groundwater concentration data.
4.4 Quality Control
Field equipment blank and trip blank samples did not contain compounds at concentrations
above laboratory method detection limits. QC samples confirmed that data is usable for its
intended purpose.
4.5 Data Review and Validation
This section provides an evaluation of the laboratory analytical data for the completeness of data
package deliverables. Additionally, field data was reviewed to verify completion of required
documentation. A copy of the laboratory analytical reports is provided in Appendix A.
Field activities were documented on groundwater sampling logs. Groundwater samples were
appropriately labeled, stored in sample containers on ice, and delivered to Shealy in good
condition and properly preserved. The sample container chain -of -custody forms were forwarded
with the samples to the analytical laboratory.
The samples were analyzed for parameters as detailed in Section 3.4. For the November 2018
sampling event, one trip blank accompanied the cooler sent to the laboratory for analysis of
VOCs by EPA Method 8260. VOCs were not detected in the method blanks or trip blanks.
Sample criteria were met for the primary sample. The surrogate, laboratory control sample, and
MS/MSD recoveries and precision on client samples were within the advisory limits. Matrix spike
and matrix spike duplicates that were performed on non -project samples were not evaluated
because matrix similarity to project samples could not be assumed.

5.0 FINDINGS AND RECOMMENDATIONS
The findings of this report are as follows:
The groundwater flow direction in the shallow aquifer (3 to 25 feet bls) is estimated to be
to the north;
C11-C22 Aromatics were detected at a concentration above 2L Standards in MW-6R.
Compounds were not detected above 2L Standards in the remaining nine monitoring
wells sampled;
Visual evidence of water supply wells within a 500-foot radius of the site was not
observed. Two water supply wells were visually observed within 1,000 feet to the north of
the site;
Dutch Buffalo Creek is located approximately 300 feet to the west of the source area; and
Based on measured groundwater concentrations, petroleum vapor intrusion is likely not a
concern for this site.
Based on the current and historical results, Terracon offers the following recommendations:
Conduct at least two (2) additional sampling events of monitoring well network to monitor
for temporal trends particularly in monitoring well MW-6R, which was recently installed.
Obtain top -of -casing elevations via a survey of monitoring wells TP-1, TP-2, MW-4R, and
MW-6R during the next sampling event.
