EXECUTIVE SUMMARY
This executive summary section provides an abbreviated reporting of our Site observations and
findings. Refer to the main text and appendices for a complete reporting of our observations and
findings.
ESP Associates, Inc. (ESP) has completed a Subsequent Monitoring Report documenting
assessment activity performed at the Rimtrax Corporation site (Incident No. 7079). The site is an
approximate 5.898-acre developed site (Tax Parcel No. 02526104) located at 10701 Reames Road in
Charlotte, Mecklenburg County, North Carolina. This report was completed to summarize the
findings of assessment activities performed on June 1, 2023, in accordance with North Carolina
Department of Environmental Quality (NCDEQ), Task Authorization No. 1, approved on May 23,
2023.
The work was performed as part of the State Lead Contract #N70522-D between NCDEQ and ESP.
This report was prepared in general accordance with the 15A NCAC 2L .0115 regulations and the
NCDEQ Underground Storage Tank (UST) Section Guidelines for Assessment and Corrective Action
for UST Releases, January 2021, under the supervision of Christopher J. Ward, North Carolina
registered professional geologist (North Carolina License No. 1600).
On June 1, 2023, ESP performed the following field activities:
• Gauging static water levels in site monitoring wells MW-2R, MW-5R and MW-6R;
• Collecting groundwater samples from monitoring wells MW-2R and MW-5R, along with
a field duplicate. Although planned, ESP was unable to obtain a water sample from
monitoring well MW-6R as the well was considered dry due to insufficient recharge
following purging; and
• Collecting surface water sample SW-1 from the unnamed intermittent creek along the
eastern boundary of the site.
Collected water samples were analyzed for volatile organic compounds (VOCs) for comparison to
both North Carolina Groundwater Quality Standards 15A NCAC 2L .0202 (2L Standards) and Gross
Contaminant Levels (GCLs).
Results of the assessment activities revealed the following:
• Static water level depths ranged from 7.55 ft to 14.70 ft bTOC.
• The general direction of groundwater flow beneath the site is to the north-northeast.
• The site and surrounding areas are connected to municipal water provided by Charlotte
Water.

Rimtrax Corporation (Incident #7079) July 25, 2023
iv
• No active water supply wells are located within 1,000-feet of the site;
• Due to the lack of significant recharge following purging of MW-6R, a sufficient volume
of water was not available for sampling.
• MTBE was the only analyte detected above its 2L standard of 20 µg/L in monitoring well
MW-2R (238 µg/L);
• In monitoring well MW-5R, analytes generally increased in concentrations with benzene
(356 µg/L), ethylbenzene (1,220 µg/L), isopropylbenzene (72.9 µg/L), MTBE (102 µg/L),
naphthalene (477 µg/L), and n-propylbenzene (292 µg/L) detected above their respective
2Lstandards; and
• The only analyte detected in surface water sample SW-1 was ethylbenzene at an estimated
concentration of 0.45J µg/L, which is significantly below its 2L standard of 600 µg/L.
The general trend in groundwater contaminant concentrations at the site has been relatively stable
since 2020. Groundwater concentrations have remained above 2L standards; however, no GCLs
have been exceeded since 2006.
Based on the above results, ESP offers the following recommendations:
• Continue to sample site monitoring wells and surface water on a semiannual basis to further
understand concentration trends and plume stability;
• Use low flow sampling to collect a representative groundwater sample from MW-6R,
which is a low producing monitoring well; and
• Install oxidation sleeves in monitoring wells MW-2R and MW-5R to attempt to reduce
VOC concentrations.

1.0 INTRODUCTION
1.1 Site Setting
The Rimtrax Corporation site is an approximate 5.898-acre developed site (Tax Parcel No. 02526104)
located at 10701 Reames Road in Charlotte, Mecklenburg County, North Carolina (see Figures 1
and 2). The site includes an approximate 21,805-sqft active service garage/office building built in
1977 along with paved parking on the southwestern and southeastern portions of the tax parcel while
the northern portion of the tax parcel includes dirt and gravel surfaces. The on-site structure is
currently occupied by Carolina CAT Rental Store (owned by CTE Reams Road LLC). The site is
bounded to the north by Maxi Crane Works commercial property, to the east by an Estes Express
Lines commercial facility, to the west by an equipment rental commercial facility, and to the south
by Old Reames Road and beyond by a gas station.
1.2 Site Geology and Hydrogeology
A consideration of surface and subsurface drainage and geology are of interest since they provide
an indication of the direction that contamination, if present on-site or off-site, could be transported.
The site is located within the Charlotte Belt of the Piedmont Physiographic Province. The
Piedmont Physiographic Province generally consists of low to medium elevation, rounded hills,
and long rolling northeast to southwest trending ridges with incised creeks and river channels.
Rock at the site is described as Metamorphosed Quartz Diorite - foliated to massive. In-place
chemical and physical weathering of parent rocks typically form residual soils in the Piedmont
region. Weathering is facilitated by the presence of fractures, joints, and less resistant minerals in
the rock. In areas not altered by erosion, alluvial deposition or the activities of man, the typical
residual soil profile consists of clay-rich unconsolidated materials at the surface, transitioning to
sandy silts and silty sands at depth. Typically, the boundary between soil and rock is not sharply
defined. This transitional zone is termed “partially weathered rock” or saprolite. Information
obtained from the Web Soil Survey for Mecklenburg County depicts soils on the site as Cecil
sandy clay loam, 2 to 8 percent slopes, moderately eroded (CeB2); Cecil sandy clay loam, 8 to 15
percent slopes, moderately eroded (CeD2); and Urban land (Ur).
In the Piedmont, groundwater generally occurs in pore spaces within soils and in the structural
features present in the underlying rock (i.e., joints, fractures, and faults). Recharge to the water
table is primarily by precipitation infiltrating the surficial soils and percolating downward under
Subsequent Monitoring Report ESP Project No. 23-00200-008
Rimtrax Corporation (Incident #7079) July 25, 2023
2
the influence of gravity to the water table. Typically, the water table is not a level surface, but a
subdued reflection of the land surface. The depth to the water table is not consistent and is
dependent upon several factors that include the amount of rainfall, permeability of the soil, the
extent of fracturing in the underlying rock and the influences of groundwater pumping.
The direction and movement of groundwater through soil is generally dependent on soil type, the
presence of relict structures, and the textures of the underlying rock. Fractures, faults, folds, and
foliation planes affect the migration of groundwater in rock. No major geologic features (faults,
etc.) are present at or near the site. Groundwater typically flows in directions parallel to the ground
surface and under the influence of gravity, migrates to discharge points such as surface water
features, the toes of slopes or natural springs. Fluctuations in the depth of the water table can be
expected depending on variations in precipitation, surface water run-off and other factors.
Normally, the highest levels of the water table occur in late winter and spring and the lowest levels
occur in the late summer and fall. Based on historical data and June 1, 2023 water level
measurements, groundwater at the site is expected to flow generally to the north and northeast.
1.3 Surface Water
A drainage steam is located along the site’s eastern boundary (see Figures 1 and 2). The drainage
is a natural intermittent stream and serves as a tributary of Dixon Branch Watershed. This stream is
the only surface water feature within 500 feet of the site.
1.4 Water Supply Wells
Based on previous receptor surveys conducted by others, a water supply well (WSW-1) was
identified on a down-gradient property located at 10815 Reames Road (currently Estes Express
Lines), approximately 275 feet northeast of the source area (see Figure 2). The water supply well
at the Estes Express Lines property was reportedly abandoned. According to the receptor
information, the remaining properties near the site are reportedly connected to municipal water.

2.0 SITE HISTORY
The following description of historical site activities was obtained from a report titled “State-Lead
Monitoring Report, Rimtrax Corporation, 10701 Reames Road, Charlotte Mecklenburg County,
North Carolina” dated February 10, 2021, by Terracon Consultants Inc. (Terracon).
• The site and surrounding areas are connected to municipal water provided by Charlotte
Water.
• The site’s former UST system comprised of one 1,034-gallon diesel UST and one 987-
gallon gasoline UST and associated piping was removed in September 1991 when a leak
of petroleum constituents was discovered as a result of corrosion of the tanks.
Approximately 180 cubic yards of petroleum impacted soils were removed from the
former tank basin to a depth of sixteen feet.
• Monitoring wells MW-1 through MW-12 were installed between December 1991 and
May 1992. Petroleum constituents exceeded GCLs in MW-5.
• Free product recovery was performed from MW-6 by Cooper Environmental Inc. (CEI)
from March to June of 1994. Following free product recovery, CEI conducted a soil
venting pilot study (feasibility study) and installed additional monitoring well MW-5A.
• In June 1994, a temporary air sparge well (AS) and a soil vapor extraction (SVE) point
were installed as part of a Corrective Action Plan (CAP). Petroleum constituents were
detected that exceeded GCLs in MW-5A. A permanent, on-site SVE system was
subsequently installed.
• CEI performed multiple follow-up sampling events on a semi-annual basis from 1995
through 1999. Responsibility for the site remediation was given to The Structures Group
(TSG).
• In 2002, TSG installed two replacement monitoring wells that were destroyed due to
exposure to heavy machinery and large construction vehicles over time. The wells
replaced were not specified. TSG abandoned the on-site monitoring wells in November
2004. It is unclear as to the reasoning behind the abandonment of the monitoring wells.
It is also unclear when the remediation system was deactivated and removed from the
site.
• During a visit to the site in July 2019, Terracon noted a large portion of the source area
had been paved with concrete and fresh gravel had been placed on the site after the
current tenant occupied the property. After multiple attempts to locate the on-site wells,
Terracon was unable to locate any monitoring wells. Terracon also spoke with several
employees of the on-site tenant The CAT Rental Store regarding monitoring well
locations. Terracon also contacted the adjacent facility to the east regarding the use of a
water supply well formerly located on the property. A water supply well use

questionnaire was sent by certified mail to the adjacent property owner on July 16, 2019.
According to Mr. Kevin Fitz, Director of Facility Maintenance for Estes Express Lines,
the supply well was formerly utilized to supply water for the fire suppression system at
the facility. According to Mr. Fitz, the facility has been connected to municipal water
and the water tower has been drained, but the supply well has not been properly
abandoned.
• On October 9, 2019, Terracon installed monitoring well MW-5R in proximity to the
former location of MW-5. Terracon collected a soil sample (SB-01) from a depth of 5-10
ft below ground surface (bgs). A groundwater sample was also collected from MW-5R
which revealed that benzene, ethylbenzene, isopropylbenzene, MTBE, naphthalene, n-
propylbenzene, 1,2,4 trimethylbenzene, total xylenes, and several aromatics were present
above 2L standards.
• Terracon personnel mobilized to the site on November 30, 2020 to install two
additional groundwater monitoring wells (MW-2R and MW-6R) to replace destroyed
wells in their respective locations and evaluate current groundwater conditions.
Monitoring well MW-6R was installed north of the on-site vehicle wash bay.
Monitoring well MW-2R was installed southwest of the on-site drainage feature within
a vehicle staging area. The two monitoring wells were advanced to a depth of
approximately 18 feet bgs.
• On December 31, 2020, Terracon collected groundwater samples from monitoring
wells MW-2R, MW-5R, and MW-6R and a surface water sample. Benzene (254 µg/L),
ethylbenzene (905 µg/L), MTBE (34.2 µg/L), n-propylbenzene (195 µg/L), and
naphthalene (290 µg/L) were detected in well MW-5R at concentrations that exceed
their respective 2L standards. MTBE was detected in well MW-2R (496 µg/L) at a
concentration that exceeds its respective 2L standard. Various other constituents of
concern were detected in wells MW-2R, MW-5R, and MW-6R at concentrations below
their respective 2L standards. MTBE (0.75 µg/L) was detected in the surface water
sample collected from the on-site drainage feature at a concentration below the 2L
standard for MTBE.
• On March 31, 2021, Terracon collected groundwater samples from the on-site
monitoring wells MW-2R, MW-5R, and MW-6R. Benzene (244 µg/L), ethylbenzene
(964 µg/L), MTBE (30.6 µg/L), n-propylbenzene (207 µg/L), naphthalene (321 µg/L)
and total xylenes (660.9 µg/L) were detected in MW-5R above their respective 2L
standards. MTBE was detected in MW-2R (297 µg/L) above its 2L standard while
benzene (11.9 µg/L) was detected in MW-6R above its 2L standard. Various other
constituents of concern were detected in wells MW-2R, MW-5R, and MW-6R at
concentrations below their respective 2L standards. No constituents were detected
above the GCLs.
• Terracon stated in their February 10, 2021 report, that although MTBE is present in the
surface water sample collected in December 2020, the RBCA Tool Kit® Domenico

Model with First-Order Decay model simulation results indicate the concentrations will
not exceed the regulatory standards. The GSI Mann-Kendall Tool Kit® modeling
results indicate most of the detected constituent concentrations in the groundwater are
decreasing. Historical analytical data support biodegradation conditions at the site.
• On December 6, 2021 and on March 7, 2022, Terracon collected groundwater samples
from site monitoring wells MW-2R, MW-5R, and MW-6R and surface water sample
SW-1. Benzene, ethylbenzene, MTBE, and n-propylbenzene were detected above 2L
standards in MW-5R while MTBE was the only analyte detected above 2L standards
in MW-2R or surface water sample SW-1. No analytes were reported above GCLs.
Historical groundwater elevations and analytical results are provided in Appendix A.

3.0 FIELD ACTIVITIES
Field activities performed by ESP on June 1, 2023, included:
• Gauging static water levels in site monitoring wells MW-2R, MW-5R and MW-6R;
• Collecting groundwater samples from monitoring wells MW-2R and MW-5R, along with
a field duplicate. Although planned, ESP was unable to obtain a water sample from
monitoring well MW-6R as the well was considered dry due to insufficient recharge
following purging; and
• Collecting surface water sample SW-1 from the unnamed intermittent creek along the
eastern boundary of the site.
Sample locations are depicted on Figure 2. Field logbook entries along with water level survey
forms, groundwater sampling forms, and field instrument calibration forms were completed in the
field to document site activities (see Appendix C). Photographs are provided in Appendix B.
Details of field activities are provided below.
3.1 Water Level Gauging
On June 1, 2023, prior to purging or collecting groundwater samples, depth to groundwater from
the top of casing (TOC) within each monitoring well was measured and recorded using a
decontaminated electronic water level meter. The water level measurements were collected by
first removing covers and plunger caps from all site monitoring wells and allowing water within
the wells to stabilize. The electronic water level meter probe was then lowered into the well and
the depth to water measured relative to the well’s TOC.
As noted on Table 1, static water level depths ranged from 7.55 ft to 14.70 ft below top of casing
(ft bTOC). Figure 3 depicts the groundwater elevations based off a benchmark of 100.00 ft given
to the MW-5R TOC. As depicted on Figure 3, groundwater flow beneath the site is toward the
north-northeast.
3.2 Groundwater Sampling
On June 1, 2023, groundwater samples were collected from monitoring wells MW-2R and
MW-5R. Due to the lack of significant recharge following purging of MW-6R, a sufficient volume
Subsequent Monitoring Report ESP Project No. 23-00200-008
Rimtrax Corporation (Incident #7079) July 25, 2023
7
of water was not available for sampling. Less than one bailer of very turbid groundwater was
recovered from MW-6R after a 30-minutes pause to the purging process and thus was not suitable
for sampling.
Groundwater samples were collected using dedicated and disposable polyvinyl chloride (PVC)
bailers (1.5” x 3’) attached to braided nylon rope. Prior to groundwater sample collection, each
well was purged using the bailer. During purging, water quality parameters including pH,
conductivity, temperature, and turbidity were measured using calibrated field water quality
instruments. Readings were taken at the start of purging and periodically until a minimum of three
well volumes were removed from the well and water quality parameters stabilized. Following
purging, a groundwater sample for laboratory analysis was collected from the well using the bailer.
The water quality parameters were recorded on groundwater sampling forms along with time,
water level depth, and cumulative volume of water purged (see groundwater sampling forms in
Appendix C).
Groundwater samples were collected following Guidelines for Sampling by the Underground
Storage Tank Section, Division of Waste Management, North Carolina Department of
Environmental Quality (NCDEQ, 2022). Groundwater samples were placed in laboratory-
prepared vials preserved with hydrochloric acid (HCl), labeled, and stored on ice in a cooler for
subsequent delivery under standard chain-of-custody (COC) procedures to Pace Analytical (Pace),
a North Carolina-certified laboratory, located in Huntersville, North Carolina, for analysis. The
groundwater samples were analyzed for VOCs by EPA Method 6200B including MTBE, ethylene
dibromide (EDB), and isopropyl ether (IPE).
3.3 Water Supply Well Sampling
No water supply wells were sampled as part of this field effort as no active water supply wells are
reported to be located within 1,000-feet of the site. The site and vicinity properties are reportedly
connected to municipal water.
3.4 Surface Water Sampling
On June 1, 2023, a surface water sample (SW-1) was collected from the unnamed intermittent
creek that runs along the eastern boundary of the site (see Figure 4). SW-1 was collected from a
portion of the creek that was accessed near MW-2R and was the approximate location of previous
surface water sampling events. SW-1 was collected by dipping a new unpreserved laboratory
bottle into the surface water body. The water was then poured from the unpreserved bottle into the
Subsequent Monitoring Report ESP Project No. 23-00200-008
Rimtrax Corporation (Incident #7079) July 25, 2023

laboratory provided preserved glass sample vials. A surface water sampling sheet was filled out
with water quality parameters measured at the time of sample collection (Appendix C).
3.5 Field Quality Control Sampling and Analysis
A field duplicate groundwater sample was collected on June 1, 2023 from MW-5R and analyzed
for VOCs by EPA Method 6200B including MTBE, EDB, and IPE to assess variance between
collected samples.

4.0 ANALYTICAL RESULTS
Results of the laboratory analysis of groundwater samples MW-2R and MW-5R and surface water
sample SW-1 are tabulated in Table 2. As noted in Table 2, the analytical results are compared
to both 2L standards and GCLs. The Pace laboratory analytical report is provided in Appendix
D.
No analytes were detected at concentrations exceeding their respective GCLs; however, various
analytes were detected at concentrations greater than their respective 2L groundwater standards in
the two sampled monitoring wells while no analytes were detected above 2L standards in surface
water sample SW-1 (see Table 2 and Figures 4 and 5). A summary of the analytical results is as
follows:
• MTBE was the only analyte detected above its 2L standard of 20 µg/L in monitoring well
MW-2R (238 µg/L);
• In monitoring well MW-5R, analytes generally increased in concentrations with benzene
(356 µg/L), ethylbenzene (1,220 µg/L), isopropylbenzene (72.9 µg/L), MTBE (102 µg/L),
naphthalene (477 µg/L), and n-propylbenzene (292 µg/L) detected above their respective
2Lstandards; and
• The only analyte detected in surface water sample SW-1 was ethylbenzene at an estimated
concentration of 0.45J µg/L, which is significantly below its 2L standard of 600 µg/L.
A comparison of groundwater laboratory analytical results from the June 1, 2023 sampling event
to the March 7, 2022 sampling event reveals the following:
• MTBE concentrations in MW-2R decreased slightly from the March 7, 2022 sampling
event to the June 1, 2023 sampling event.
• Benzene and MTBE concentrations in MW-5R both decreased from the March 7, 2022
sampling event to the June 1, 2023 sampling event.
• The other analytes detected above 2L standards in MW-5R (i.e., ethylbenzene,
naphthalene, cumene, and n-propylbenzene) increased somewhat from the March 7, 2022
event to the June 1, 2023 event.
The general trend in groundwater contaminant concentrations at the site has been relatively stable
since 2020. Groundwater concentrations have remained above 2L standards; however, no GCLs
have been exceeded since 2006.

The general trend in groundwater contaminant concentrations at the site has been relatively stable
since 2020. Groundwater concentrations have remained above 2L standards; however, no GCLs
have been exceeded since 2006.
Based on the above results, ESP offers the following recommendations:
• Continue to sample site monitoring wells and surface water on a semiannual basis to further
understand concentration trends and plume stability;
• Use low flow sampling to collect a representative groundwater sample from MW-6R,
which is a low producing monitoring well; and
• Install oxidation sleeves in monitoring wells MW-2R and MW-5R to attempt to reduce
VOC concentrations.
