2.0 EXECUTIVE SUMMARY
ATC Associates of North Carolina, P.C. (ATC) submits this Groundwater Monitoring Report
documenting the results of a groundwater monitoring event at the Former Rudisill’s 66 site. The
report has been completed based the March 28, 2023, Task Authorization (TA-01) by the Trust
Fund Branch of the Underground Storage Tank (UST) Section, Division of Waste Management,
North Carolina Department of Environmental Quality (NCDEQ). The work was performed as part of
the State Lead Contract # N70522-B between the NCDEQ and ATC. The incident is associated
with releases of gasoline from the UST system removed in April 1996.

As part of TA-01 ATC conducted a groundwater sampling event including the sampling of four
groundwater monitoring wells (MW-1, MW-2, MW-4, and MW-6) on April 5, 2023. The purpose of
this report is to evaluate the current status of the groundwater quality at the Former Rudisill’s 66
(site) located at 2707 1st Avenue in Hickory, Catawba County, North Carolina. The scope of
services also included evaluation of a reported surface water body within 500 feet southwest of the
source area. The following site conditions are noted based on the recent and historical assessment
activities and are listed in the Conceptual Site Model (Appendix A):

 No active water supply wells are located within 1,500 feet of the source area. Municipal water
is provided to the site and surrounding properties.
 No surface water bodies are located within 500 feet of the source area.
 Concentrations of 1,2-dibromoethane (ethylene dibromide or EDB) exceeded the Gross
Contamination Level (GCL) in MW-2.
 Concentrations of several volatile organic compounds (VOCs) were reported in each of the
monitoring wells at concentrations exceeding the 15A NCAC 02L .0202 Groundwater
Quality Standards (2L Standards).
 The depth to groundwater ranged from 28.39 feet below top of casing (ft-toc) to 29.95 ft-toc.
Groundwater flow based on the April 5, 2023 data is indicated to be to the southeast;
however, prior reports indicate a more southerly groundwater flow direction.

The risk classification for the incident is Intermediate due to the exceedances of the GCL for EDB
in well MW-2. EDB concentrations were less than the GCLs between July 2018 and June 2021.
However, concentrations increased to 63.7 micrograms per liter (µg/L) and 121 µg/L for the
October 2021 and January 2022 sampling events, respectively. The April 5, 2023 EDB
concentration was 77.8 µg/L, indicating an approximate 35% decrease from the January 2022
concentration, but still exceeding the GCL. ATC recommends considering remedial actions to
reduce the EDB concentrations to below the GCL, with possible actions including chemical
injection or air sparging.

3.0 SITE DESCRIPTION
3.1 Site Characterization
ATC, under contract to the NCDEQ, provided environmental services at the Former Rudisill’s 66
Motors site, which is located at 2707 1st Avenue in Hickory, Catawba County, North Carolina.
Figure 1 depicts the site on a topographic map. Former Rudisill’s 66 (site) is comprised of 0.34
acres and is developed as a vehicle repair facility. Adjacent properties to the north, across a
railroad line, are occupied by residences; the adjacent property to the east across 27th Street SW,
is occupied by Longview Drug; the adjacent property to the south is occupied by the Resurrected
Life Baptist Church; and the adjacent property to the west is occupied by Dollar General.

3.2 Site Background
The UST system at the site consisted of two 3,000-gallon gasoline tanks, one 2,000-gallon
gasoline tank, one 550-gallon used oil tank, and one 550-gallon heating oil tank that operated at
the site until 1990s. In April 1996, the USTs and associated piping were removed. Soil analytical
results indicated total petroleum hydrocarbon (TPH) contamination ranging from 940 ppm to
40,000 ppm in the closure samples. No investigative or remedial activities were performed
between 1996 and 1999. In July 1999, the site was accepted into the State Lead Cleanup
Program.

In August 2003, S&ME performed a Limited Site Assessment (LSA) that included a receptor
survey and the installation and sampling of monitoring wells MW-1 through MW-3. Water supply
wells or surface water features were not identified within 1,000 or 500 feet of the source area,
respectively, and municipal water is provided to the area. Monitoring wells MW-1 (former
dispenser island) and MW-2 (former UST basin) indicated groundwater contamination.
Groundwater sampling in February 2004 indicated similar results.

In February 2006, six soil borings were installed by Force Environmental, three of which were
converted into monitoring wells MW-4 through MW-6. Groundwater contamination was
discovered in MW-6 (former UST basin) above both the 2L standards and GCLs. Groundwater
was determined to be delineated with the installation of these wells. A surface water body
(“small surface stream”) was reportedly located approximately 425 feet southwest of the source
area. This surface water body was not reported to be present in the LSA Report or subsequent
reports.

Between May 2006 and September 2020, groundwater monitoring events were conducted at
the site by S&ME. Constituents generally decreased over time with Well Booms® and oxygen-
releasing media (O-SOX) installed annually in wells MW-1, 2, 4 and 6 in order to aide in
contaminant degradation. During the sampling in September 2020, S&ME sampled all six
monitoring wells and the total concentrations of dissolved phase petroleum constituents
increased in MW-1 and MW-6, decreased in MW-2, and remained stable in MW-3, MW-4, and
MW-5 since the previous sampling in May 2020. Multiple constituents were detected at
concentrations above their 2L standards in wells MW-1, MW-2, MW-4 and MW-6. EDB was
reported at a concentration of 72 µg/L in well MW-1, which is in excess of its GCL. S&ME
recommended reducing EDB below the GCL in monitoring well MW-1 and then closing the site
with a Notice of Residual Petroleum

In June 2021, Terracon conducted a groundwater monitoring event and collected samples from
MW-1 through MW-6. Multiple constituents were detected at concentrations in exceedance of
their 2L standards in MW-1, MW-2, MW-4, and MW-6. No constituents were detected above

their GCLs. The total concentrations of dissolved phase petroleum constituents increased in
MW-2, decreased in MW-1 and MW-6, and remained stable in MW-3, MW-4, and MW-5.

Between October 2021 and January 2022, Terracon conducted two groundwater monitoring
events and collected samples from MW-1, MW-2, and MW-6. Multiple constituents were
detected at concentrations above their 2L standards in MW-1, MW-2, and MW-6. In both events,
MW-2 had increasing EDB concentrations above its GCL. The total concentrations of dissolved
phase petroleum constituents on-site are generally stable. Terracon recommended the
continued monitoring of groundwater monitoring wells to evaluate plume stability, and reducing
the EDB levels in MW-2 to achieve site closure with a Notice of Residual Petroleum.

3.3 Site and Regional Geology

According to the Geologic Map of the Charlotte 1° x 2° Quadrangle, North Carolina and South
Carolina, produced by Goldsmith, et. al. in 1988, the site lies within the Inner Piedmont 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. The rocks in the site area are predominantly described
as sillamanite-mica schist. 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 County Soil Survey for
Catawba County, depicts soils on the site as Clifford sandy loam (CfB). Based on the well logs
for wells MW-1 through MW-3 included in the LSA Report, soil was described as clayey silt and
sandy, clayey silt to approximately 20 feet below ground surface (ft-bgs) and sandy, silty clay to
termination depths of 40 ft-bgs. Bedrock was not reported to the termination depths of 40 ft-bgs.

3.4 Site and Regional Hydrogeology

The shallow aquifer occurrence varies in depth from ground surface at springs, creeks, and
rivers to as deep as 50 feet or more beneath upland surfaces in some parts of the Piedmont.
Water in the alluvium or unconsolidated residual material, including saprolite and PWR, usually
behaves as an unconfined aquifer, or water table, and will yield water with head elevation
equivalent to the first elevation where water was encountered. Permeability varies with lithology
and is typically relatively low in residual soils, with higher permeability in saprolite or PWR due
to relict rock texture and variable susceptibility to weathering exhibited by different minerals in
the rock. Groundwater flow in residual soils or alluvium is usually in rough concurrence with
local topographic conditions and is toward local drainage features. Based on historical
groundwater elevations from the site monitoring wells, groundwater flow across the site is
generally to the south, although the April 5, 2023 groundwater data (without data from MW-3 or
MW-5) indicate groundwater flow to the southeast. Depth to groundwater in the overburden
aquifer at the site has historically ranged from approximately 23.5 to 34.8 ft-toc.

The bedrock fractures or other planar features of the Piedmont Physiographic Province
generally constitute the bedrock aquifer, with the surrounding rock material being effectively
impermeable. Along with fractures, contacts between rock bodies probably constitute zones of
significant groundwater occurrence in the bedrock. The surrounding material and overlying
residuum tend to make the bedrock aquifer a semi-confined aquifer. That is, the overlying water

and soil weight normally results in pressure that causes water in a borehole, which intersects a
fracture or other feature, to rise above the elevation of the fracture or feature. Modern water
supply wells in the Piedmont are typically installed with a surface casing through the
unconsolidated material, and an open borehole into the bedrock where water-bearing fractures
are encountered.

4.0 GROUNDWATER CHARACTERIZATION
While at the site to sample the monitoring wells, ATC conducted a site reconnaissance by
walking along roads and open areas on commercial properties south of the site to check for the
reported surface water body located approximately 425 feet southwest of the site. No surface
water bodies were identified within 500 feet of the site during this site reconnaissance. A
drainage feature was indicated on a nearby parcel to the west, 330 feet southwest of the site.
Photographs of the drainage feature from approximately 480 feet from the site is included in
Appendix B, along with a county GIS image of the area and drainage feature.

4.1 Groundwater Levels
On April 5, 2023, groundwater levels were measured in monitoring wells MW-1, MW-2, MW-4, and
MW-6. Figure 2 depicts a site map with well locations. Recent and historical depth to
groundwater data are summarized in Table 1. The depth to groundwater in the shallow
monitoring wells ranged from 28.39 ft-toc in MW-4 to 29.95 ft-toc in MW-2. Based on the
groundwater levels and calculated groundwater elevations, groundwater was determined to flow
to the southeast with a horizontal hydraulic gradient of 0.022 feet per foot (Figure 3). Field
notes and site photographs from the April 5, 2023 groundwater monitoring event are presented
in Appendix B.

4.2 Groundwater Quality
On April 5, 2023, groundwater samples were collected from monitoring wells MW-1, MW-2, MW-4,
and MW-6. Prior to sampling, the wells were purged a minimum of three well volumes. Upon
completion of purging activities, water quality field parameters were measured in each well. Field
parameters are included in Table 2. The water samples were collected in laboratory-supplied,
preserved containers; entered into chain-of-custody control; placed on ice; and delivered to Pace
Analytical Services, LLC in Huntersville, NC. The groundwater samples were analyzed by EPA
Method 6200B for VOCs including ethanol and oxygenates. The analytical report is included as
Appendix C.

Groundwater analytical results from the April 5, 2023 monitoring event are summarized in Table 3.
Historical groundwater analytical results are summarized in Table 4. Figure 4 depicts dissolved-
phase compounds detected above 2L Standards in sampled monitoring wells. Groundwater
analytical results indicated the following:

 EDB concentration exceeded the GCL in MW-2.
 Benzene concentrations exceeded the 2L Standard in MW-1, MW-2, and MW-6
(Figure 5).
 EDB concentrations exceeded the 2L Standard in MW-1, MW-2, MW-4, and MW-6
(Figure 6).
 Other VOCs exceeded the 2L Standards in wells MW-1, MW-2, MW-4, and MW-6.

As part of ATC’s quality assurance and quality control (QA and QC) measures, a data review of the
laboratory report was conducted. During the review, it was found that the samples were received

from the laboratory in acceptable condition and properly preserved. The samples were analyzed
within correct holding times and reported within the laboratory report, and the chain-of-custody was
properly completed by all parties. The laboratory QC report shows that an internal blank was
analyzed for EPA Method 6200B. The laboratory fortified blank (LFB) and laboratory control
sample (LCS) data results were also provided for EPA Method 6200B. A field blank was also
analyzed during the groundwater monitoring event, and VOCs were not detected in the field blank
sample. Refer to the laboratory report in Appendix B for details regarding QA results for the
laboratory samples and any noted exceptions. Overall, ATC concludes that the laboratory results
are usable and any exceptions do not significantly impact the conclusions presented in this report.

5.0 CONCLUSIONS AND RECOMMENDATIONS
On behalf of the Trust Fund Branch of the UST Section, ATC conducted a groundwater sampling
event including the sampling of four groundwater monitoring wells (MW-1, MW-2, MW-4, and MW-
6.) on April 5, 2023. The following site conditions are noted based on the recent and historical
assessment activities and are listed in the Conceptual Site Model (Appendix A):

 No active water supply wells are located within 1,500 feet of the source area. Municipal water
is provided to the site and surrounding properties.
 No surface water bodies are located within 500 feet of the source area.
 Concentrations of EDB exceeded the GC) in MW-2.
 Concentrations of VOCs were reported in each of the monitoring wells at concentrations
exceeding the 2L Standards.
 The depth to groundwater ranged from 28.39 ft-toc to 29.95 ft-toc. Groundwater flow based
on the April 5, 2023 data is indicated to be to the southeast; however, prior reports indicate a
more southerly groundwater flow direction.

The risk classification for the incident is Intermediate due to the exceedances of the GCL for EDB
in well MW-2. EDB concentrations were less than the GCLs between July 2018 and June 2021.
However, concentrations increased to 63.7 µg/L and 121 µg/L for the October 2021 and January
2022 sampling events, respectively. The April 5, 2023 EDB concentration was 77.8 µg/L, indicating
an approximate 35% decrease from the January 2022 concentration, but still exceeding the GCL.
ATC recommends considering remedial actions to reduce the EDB concentrations to below the
GCL, with possible actions including chemical injection or air sparging.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPAMethod 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
