2.0 EXECUTIVE SUMMARY
ATC Associates of North Carolina, P.C. (ATC) has completed a Groundwater Monitoring Report
(GMR) documenting a monitoring event conducted on October 17, 2019, of seven on-site
monitoring wells at Hodge’s Exxon, located at 145 East Broad Street, Statesville, Iredell County,
North Carolina. The GMR is being performed based on a October 11, 2019, Task Authorization
(TA-03) 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 is
being performed as part of the State Lead Contract #N17004 between NCDEQ and ATC.
A release associated with the removal of four former on-site petroleum USTs was reported in April
1991. During a Limited Site Assessment (LSA) in 1999, a second release from the heating oil UST
was confirmed, and it was removed later in 1999. The site is currently occupied by ACE Cash
Express Money Service and HD Wireless with no retail fuel operations.
As part of the TA, ATC collected groundwater samples from three monitoring wells, MW-1R,
MW-3, and MW-4. ATC was unable to sample monitoring wells MW-02, MW-05 and MW-06 due
to obstructions. ATC was unable to collect a sample from monitoring well MW-07 because the well
was purged dry during sampling and did not recharge. Historically, groundwater sampling results
from monitoring wells MW-05 and MW-06 indicated no detections of VOCs exceeding detection
limits. The most recent sampling of monitoring wells MW-02 and MW-07 indicated only MTBE in
MW-02 at concentrations of 20 micrograms per liter (µg/L). The groundwater was analyzed for
volatile organic compounds (VOCs) including petroleum constituents. The findings from the
monitoring event indicate the following:
No water supply wells are located within 1,000 feet and no surface water bodies are
located within 500 feet of the source areas;
Light Non-Aqueous Phase Liquid (LNAPL) was not encountered during the groundwater
monitoring event;
None of the detected concentrations exceeded Gross Contaminant Levels (GCLs);
Monitoring wells MW-01R, MW-03, and MW-04 contained concentrations of several
constituents above the 2L Standards;
Based on groundwater elevation data, groundwater appears to flow toward the south, which
is consistent with previous interpretations; and
Mann Kendall trend analyses indicated a decreasing trend for concentrations in MW-1R,
stable to probably decreasing/decreasing trend in well MW-3, and a decreasing trend in well
MW-4.
Based on the above, ATC recommends evaluation of the site for closure.

3.0 SITE DESCRIPTION
3.1 Site Characterization
The NCDEQ retained ATC to provide environmental consulting services for Hodge’s Exxon,
located at 145 East Broad Street, Statesville, Iredell County, North Carolina. Figure 1 depicts the
site location on a topographic map. The site currently operates as ACE Cash Express Money
Service, and HD Wireless, a wireless retail business. Municipal water is available to the site and
vicinity.
3.2 Site Background
The site formerly operated as Hodge’s Exxon, a gasoline service station. Five USTs were used at
the site, including one 6,000-gallon gasoline UST, one 5,000-gallon gasoline UST, one 2,000-
gallon gasoline UST, one 1,000-gallon heating oil UST, and one 550-gallon waste oil UST. Four
of the USTs were installed in March 1956, the 6,000-gallon gasoline UST was installed in March
1966. In April 1991, all of the USTs, with the exception of the 1,000-gallon heating oil UST
were removed. Impacted soil was excavated from the tank basin in April 1991 to a depth of 28
feet below ground surface (bgs). A release was confirmed during the 1991 tank removal.
Because soil samples were not collected from the piping and dispenser island the UST Closure
was considered incomplete.
In January 1999, a UST Closure Addendum was prepared by Schnabel Engineering that
indicated impacted soil was present along the piping run and that a Limited Site Assessment
(LSA) was required.
A LSA was completed in July 1999 by Southeastern Geological Services Inc. (Southeastern),
that included the installation of monitoring wells MW-01, MW-02, MW-03, and MW-04 and
vertical extent well VMW-01. During the LSA, a second release was discovered associated with
the heating oil UST. Groundwater impact was identified in the monitoring well network,
including two inches of free product in monitoring well MW-04.
Subsequent to the LSA, the 1,000-gallon heating oil UST was reportedly removed in 1999. The
1999 UST Closure Report was not available for review. A Comprehensive Site Assessment
(CSA), completed in September 2000 by Southeastern included the installation of monitoring
wells MW-05, MW-06, and MW-07; groundwater monitoring; a receptor survey for the site; and
a discussion of the 1999 heating oil UST removal. According to the CSA, closure samples from
the 1999 heating oil UST removal reportedly indicated no evidence of a release. A free product
thickness of 2.90 feet was detected in monitoring well MW-04. Groundwater impact above 2L
Standards was identified in monitoring wells MW-01, MW-02, MW-03, and MW-07. No
potential receptors were identified within a 1,000 foot radius of the site.
A groundwater monitoring event on June 3, 2010, was performed by Force Environmental
Service Company, LLC (Force). During the groundwater monitoring event, monitoring wells
MW-01 and VMW-01 were observed to have accumulated large quantities of silt. A free product
thickness of 0.10 feet was detected in monitoring well MW-04, and a sheen was observed in
monitoring well MW-02. Monitoring wells MW-02, MW-03, and VW-01 indicated aliphatic

impact above GCLs. Monitoring wells MW-02, MW-03, MW-07, and VMW-01 contained
petroleum impact above 2L Standards.
In August 2010, monitoring wells MW-01 and VW-01 were abandoned due to the high content
of silt in the well screen. Monitoring well MW-01R was subsequently installed near the previous
monitoring well MW-01. A groundwater monitoring event was also performed that indicated a
free product thickness of 0.15 feet in monitoring well MW-04. Groundwater sampling results
indicated aliphatic impact above established GCLs in monitoring wells MW-02 and MW-03.
Petroleum impact of one or more constituents above 2L Standards was identified in monitoring
wells MW-01R, MW-02, MW-03, and MW-07.
An AFVR event was performed using well MW-04 in October 2010. Post-AFVR sampling was
performed in December 2010 that indicated that no measurable free product was detected in the
monitoring well network; however, impact above GCLs and 2L Standards was identified.
In August 2011, Force completed a Mobile Multi-Phase Extraction (MMPE) event and
groundwater monitoring at the site using monitoring wells MW-01R, MW-03, and MW-04 as
extraction points. Free product was not identified in the recovered groundwater. A groundwater
monitoring event was performed following the completion of the MMPE event. Monitoring well
MW-01R contained impact above the established GCL for benzene. Groundwater analytical
results for samples collected from monitoring wells MW-01R, MW-02, MW-03, MW-04 and
MW-07 indicated concentrations of one or more constituents above 2L Standards.
In September 2012, Force injected an oxygenate compound into the monitoring wells to reduce
concentrations below GCLs in the monitoring well system. Five-hundred pounds of Klozur
sodium persulfate, 680 pounds of Klozur Caustic, and 119 gallons of potable water were gravity
fed into impacted wells. A PermeOx solution was injected into two of the upgradient wells.
A groundwater monitoring report, dated March 22, 2013, did not identify impact above GCLs at
the site. Monitoring wells MW-01R, MW-03, and MW-04 contained concentrations of one or
more petroleum constituents above 2L Standards. Monitoring wells MW-02 and MW-07 were
not sampled in 2013. However, another monitoring event performed in December 2014,
indicated impact above the GCL for benzene in well MW-01R and several wells with impact
above the 2L Standard for multiple petroleum compounds.
To enhance the natural degradation of dissolved phase petroleum impact, Adventus remedial
oxygen releasing socks (ORS) were installed in monitoring wells MW-01R and MW-03 on
August 27, 2015. A groundwater monitoring event was performed in February 2016 to evaluate
groundwater quality following the ORS installation. Contaminants above 2L Standards were
observed in monitoring wells MW-01R, MW-03, and MW-04. Monitoring well MW-01R contained
benzene at a concentration exceeding the GCL.
In June 2016, ATC conducted an 8-hour AFVR event and replaced ORS at the site. The AFVR
event used monitoring wells MW-01R and MW-04 as the extraction wells. A total of 225 gallons of
petroleum-impacted groundwater and 0.99 pounds of petroleum emissions as vapor were recovered

during the event. Following the AFVR event, two ORS were installed in monitoring wells MW-
01R, MW-03, and MW-04.
ATC conducted groundwater monitoring on January 22, 2018, to further evaluate groundwater
quality. Laboratory analysis indicated a concentration of EDB above GCLs in well MW-03.
Concentrations of petroleum constituents exceeded NC 2L Standards in wells MW-01R, MW-
03, and MW-04.
ATC conducted groundwater monitoring on September 28, 2018. Petroleum constituents
exceeding 2L Standards were detected in monitoring wells MW-01R, MW-03, and MW-04;
however, no exceedances of the GCLs were indicated.
3.3 Site and Regional Geology
According to the Geologic Map of North Carolina, produced by the State of North Carolina in
1985, the site is located in the Charlotte Belt of the Piedmont Physiographic Province of North
Carolina. The rock type at the site has been identified as granite, which is crystalline igneous
rock. The shallow subsurface in most areas of the Piedmont contains residual soil overburden,
including structure-free residuum, saprolite, and partially weathered rock (PWR) that derive
from in-place weathering of the crystalline bedrock. Occasional areas containing recent deposits
of alluvium in the uppermost subsurface are found near streams and rivers. Saprolite and PWR
typically contain some relict structures from the original rock material. Depth to rock ranges
from ground surface at occasional outcrops to depths of greater than 100 feet in areas of easily
weathered rock. According to monitoring well installation records from the 1999 Phase I LSA,
the primary soil types encountered consisted of a surface layer of silty clay, followed by saprolite
mica schist.
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 the data from the
monitoring well network, shallow groundwater flows generally to the southeast, with depth to
groundwater around 21 ft bgs.
The bedrock fractures or other planar features of the Charlotte Belt 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, likely including those in the site vicinity, 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
4.1 Groundwater Levels
On October 17, 2019, groundwater monitoring was conducted using the site monitoring well
network. Water levels were gauged in monitoring wells MW-01R, MW-03, MW-04, and MW-
07. Table 1 presents monitoring well construction details. Monitoring wells MW-02, MW-05,
and MW-06 were obstructed and depth the water could not be measured. LNAPL was not
identified in the monitoring well network. Figure 2 depicts a site map. Groundwater elevation
data is summarized in Table 2. A groundwater contour map depicting groundwater flow is
presented in Figure 3, indicating groundwater flow to the south. Field notes from the October
17, 2019, groundwater monitoring event is presented in Appendix A.
4.2 Groundwater Quality
Groundwater monitoring was conducted on October 17, 2019. Groundwater samples were collected
from monitoring wells MW-01R, MW-03, and MW-04. Monitoring wells MW-02, MW-05, and
MW-06 were obstructed and could not be sampled. Monitoring well MW-07 was purged dry and
did not recharge and could not be sampled. Historically, groundwater sampling results from
monitoring wells MW-05 and MW-06 indicated no detections of VOCs exceeding detection limits.
The most recent sampling of monitoring wells MW-02 and MW-07 indicated only MTBE in MW-
02 at concentrations of 20 micrograms per liter (µg/L). During sampling activities, a three-volume
well purge was implemented prior to groundwater sample collection to ensure a representative
groundwater sample. Upon completion of purging, groundwater quality parameters were measured
in each well and are summarized in Table 3. The groundwater samples were collected in
laboratory-supplied, preserved containers; entered into chain of custody control; placed on ice; and
shipped to North Carolina accredited Pace Analytical Laboratories, located in Huntersville, NC. The
groundwater samples were analyzed by EPA Method 6200B for VOCs, including petroleum
constituents. The analytical report is included in Appendix B.
Current groundwater analytical results are summarized in Table 4. Historical groundwater analytical
results are summarized in Table 5. Groundwater analytical results indicated the following:
LNAPL was not encountered during the groundwater monitoring event;
None of the detected concentrations exceeded GCLs;
Monitoring wells MW-01R, MW-03, and MW-04 contained concentrations of several
constituents above the 2L Standards; and
Based on groundwater elevation data, groundwater appears to flow toward the south, which
is consistent with previous interpretations.

Figure 4 depicts a groundwater quality map showing detected constituents exceeding the 2L
Standards for each well.
As part of ATC’s quality assurance and quality control (QA and QC) measures, a data review of the
laboratory reports 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 lab report, and the chain of custody was
properly completed by all parties. The laboratory QC report shows that an internal blank was
analyzed for each method that was used for the original samples. The laboratory fortified blank
(LFB) and laboratory control sample (LCS) data results were also provided for each analytical
method. Methylene chloride was detected in the field blank collected on October 17, 2019, but was
not detected in any of the groundwater samples. Refer to the laboratory reports 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.
ATC completed a concentration trend evaluation using the GSI Mann-Kendall Toolkit for
Constituent Trend Analysis. Data from monitoring wells with historical LNAPL or high dissolved-
phase impact above or near the GCLs were entered into the toolkit for trend analyses. Monitoring
wells MW-1R, MW-3, and MW-4 were evaluated for primary constituents of concern which
indicated a decreasing trend for concentrations in monitoring well MW-1R, stable to decreasing
trend in monitoring well MW-3, and a decreasing trend in monitoring well MW-4. Documentation
from the Mann-Kendall trend analyses is included in Appendix C.
5.0 CONCLUSIONS AND RECOMMENDATIONS
On behalf of the Trust Fund Branch of the UST Section, ATC has completed a GMR
documenting the October 17, 2019, groundwater monitoring event for Hodge’s Exxon, located at
145 East Broad Street, Statesville, Iredell County, North Carolina. Based on the information
provided in this report, ATC offers the following conclusions:
No water supply wells are located within 1,000 feet and no surface water bodies are
located within 500 feet of the source areas;
LNAPL was not encountered during the groundwater monitoring event;
None of the detected concentrations exceeded GCLs;
Monitoring wells MW-01R, MW-03, and MW-04 contained concentrations of several
constituents above the 2L Standards;
Based on groundwater elevation data, groundwater appears to flow toward the south, which
is consistent with previous interpretations; and
Mann Kendall trend analyses indicated a decreasing trend for concentrations in MW-1R,
stable to probably decreasing/decreasing trend in well MW-3, and a decreasing trend in well
MW-4.
Based on the above, ATC recommends evaluation of the site for closure.

Notes:
1.At least four independent sampling events per well are required for calculating the trend. Methodology is valid for 4 to 40 samples.
2.Confidence in Trend = Confidence (in percent) that constituent concentration is increasing (S>0) or decreasing (S<0): >95% = Increasing or Decreasing;
≥ 90% = Probably Increasing or Probably Decreasing; < 90% and S>0 = No Trend; < 90%, S≤0, and COV ≥ 1 = No Trend; < 90% and COV < 1 = Stable.
3.Methodology based on "MAROS: A Decision Support System for Optimizing Monitoring Plans", J.J. Aziz, M. Ling, H.S. Rifai, C.J. Newell, and J.R. Gonzales,
