2.0 EXECUTIVE SUMMARY
ATC Associates of North Carolina, P.C. (ATC) has completed a Groundwater Monitoring Report
documenting a sampling event for ten site monitoring wells and one water supply well on October 13,
2022, at Amity Hill Grocery. The report has been completed based on a September 1, 2022, Task
Authorization (TA-02) 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 # N122019A between the NCDEQ and ATC.

On October 13, 2022, ATC gauged liquid levels in the site wells, sampled one water supply well (Supply
Well), and sampled ten monitoring wells (MW-1, MW-2, MW-3, MW-7, MW-9, MW-12, MW-13, MW-15,
MW-16, and DMW-1). Monitoring wells MW-5 and MW-6 were dry, MW-8 was inaccessible due to
vegetation beneath the overhead porch, monitoring wells MW-10 and MW-17 were damaged, and MW-4
and MW-11 contained measurable Light Non-Aqueous Phase Liquid (LNAPL). ATC installed petroleum
absorbing socks in monitoring wells MW-4 and MW-11. Permission to sample water supply well SW-1
was denied by the property owners. The water samples were analyzed for volatile organic compounds
(VOCs) by Standard Method (SM) 6200B including oxygenates. Site conditions based on the recent and
prior assessment activities are summarized below:

 Five drinking water supply wells are located within 1,000 feet of the source area, with water supply
wells Supply Well and SW-1 located within 250 feet of the source area. Municipal water is not
available to the area;
 No surface water bodies are located within 500 feet of the source area;
 VOCs were not detected in the water supply well sample (Supply Well);
 LNAPL was detected in monitoring wells MW-4 and MW-11 (0.24 feet LNAPL in both);
 Concentrations of benzene and ethylene dibromide (EDB) exceeded the Gross Contamination
Levels (GCLs) in the following monitoring wells: MW-1, MW-2, MW-12, MW-13, and MW-15. The
concentration of 1,2-dichloroethane (1,2-DCA) also exceeded the GCL in MW-2;
 Concentrations of VOCs exceeded the 15 NCAC 2L .0202 groundwater quality standards (2L
Standards) in the following monitoring wells: MW-1, MW-2, MW-3, MW-7, MW-12, MW-13, MW-15,
and DMW-1; and
 Depth to water at the site ranged from 35.32 feet below top of casing (ft-toc) in MW-9 to 38.20 ft-
toc in MW-15. Groundwater flow is projected to be to the north-northeast.
 An evaluation of the approximate dimensions of the VOC plume was conducted in order to further
demonstrate that the VOC plume is stable over time. The approximate area the GCL and 2L
Standard exceedances have remained relatively stable over the past five years.

The VOC plume dimension evaluation and recent and historical sampling results for the shallow perimeter
monitoring wells indicate that the VOC plume is stable, with the only exceedances of the 2L Standards in
the perimeter wells indicated in the downgradient well MW-22. Wells without historical LNAPL also
indicated stable or decreasing VOC concentrations. Wells with historical LNAPL continue to indicate
fluctuating VOC concentrations. VOCs in the deep well DMW-1 exceed the 2L Standards and appear to
be relatively stable based on the last four sampling events.

Based on the findings of the recent monitoring event and the historical remedial actions taken, ATC
recommends the following:

 Quarterly installation and/or replacement of LNAPL absorbing socks in the applicable wells,
including wells that are expected to have measurable LNAPL with water table fluctuation;
 Consider conducting Mobile Multi-Phase Extraction (MMPE) events, enhanced with air sparging
(new deeper wells in the LNAPL plume area) and air injection in selected existing shallow wells;
 Abandonment and replacement of MW-17 as a shallow side-gradient monitoring point; and
 Semi-annual groundwater monitoring events and groundwater monitoring following enhanced
MMPE events.

3.0 SITE DESCRIPTION
3.1 Site Characterization
ATC, under contract to the NCDEQ, provided environmental consulting services at the Amity Hill Grocery
site, located at 1495 Ostwalt Amity Road in Cleveland, Iredell County, North Carolina. Figure 1 depicts
the site on a topographic map. The site contains a church building for House of Prayer of Faith, which is
generally used for on-line/internet religious services. Five water supply wells have been previously
identified within 1,000 feet of the site with two additional wells within 1,500 feet of the site. Figure 2
depicts the locations of water supply wells within 1,500 feet of the subject property. Information regarding
the water supply wells is provided in Table 1. Figure 3 depicts the locations of monitoring wells on the
subject property. Municipal water is not available in the area.

3.2 Site Background
Four petroleum USTs (two 1,000-gallon gasoline and two 550-gallon diesel) were removed from the
subsurface of the site in June 1989. The petroleum release incident (No. 6677) is associated with these
former tanks. Total petroleum hydrocarbon (TPH) concentrations for soil samples collected as a part of
the UST closure activities exceeded the NCDEQ UST Section Action Limit at the time (10 milligrams per
kilogram [mg/kg]). Concentrations of up to 1,600 mg/kg TPH as gasoline and 3,200 mg/kg TPH as diesel
were detected in UST closure soil samples.

The former petroleum UST systems at the site released product to the subsurface prior to their removal in
June 1989. No USTs have been installed at the site since the removal of the former USTs. Thus, this
report documents impact conditions likely related to the former UST systems.

Monitoring wells MW-1 and MW-2 were installed at the site in 1994 by Terraine Environmental Services
(Terraine). Soil samples collected during well installation activities indicated elevated TPH concentrations.
LNAPL was present in wells MW-1 and MW-2.

In March 1998, Law Engineering and Environmental Services (Law) installed monitoring wells MW-3,
MW-4, MW-5, and MW-6. During a subsequent groundwater sampling event, LNAPL was noted in
monitoring wells MW-1, MW-2, and MW-5. Additionally, Law conducted a receptor survey that identified
six water supply wells within a 1,500-foot radius of the site.

In March 1999, Law gauged LNAPL in site monitoring wells and subsequently conducted an Aggressive
Fluid/Vapor Recovery (AFVR) event at wells MW-1, MW-2, MW-4, and MW-6. The recovery event yielded
508 gallons of fluids. No measurable LNAPL was present in the vacuum truck at the conclusion of the
event.

In October 1999, S&ME, Inc. (S&ME) oversaw the installation of eight additional monitoring wells (MW-7
through MW-14) at the site. Monitoring wells MW-15 through MW-20 and DMW-1 were then installed
under the supervision of S&ME in March 2000. According to a report from S&ME dated July 13, 2002,
wells MW-21 and MW-22 were installed by another consultant, and no record of installation is available.

Hart & Hickman conducted 96-hour Mobile Multi-Phase Extraction (MMPE) events in April 2005 and June
2006. A groundwater monitoring event conducted in July 2006 indicated LNAPL in wells MW-2, MW-4,
MW-6, MW-14, and MW-15.

A report submitted by Hart & Hickman dated July 28, 2008, identified six water supply wells within 1,500
feet of the site. Sampling of accessible water supply wells in June 2008 (SW-1, SW-2, SW-3, and SW-5)
indicated no petroleum compounds above laboratory detection limits.

In 2011, the NCDEQ contracted Progress Environmental (Progress) to conduct multiple 96-hour MMPE
events and subsequent groundwater monitoring events. The first MMPE event took place from February
28 through March 4, 2011, and removed 5,739 gallons of contaminated groundwater. The second event
was only conducted for 75-hours (from April 18 through 21, 2011) due to an upcoming religious holiday. A
subsequent groundwater monitoring well and water supply well sampling event was conducted in June
2011. Laboratory analysis showed 10 wells (MW-1, MW-2, MW-4, MW-6, MW-8, MW-11, MW-13, MW-
14, MW-15, and MW-19) contained at least one compound above GCLs. Five wells (MW-5, MW-7, MW-9,
MW-10, and DMW-1) contained at least one compound above 2L Standards, and four wells (MW-16,
MW-18, MW-20, and MW-21) contained detectable compounds below 2L Standards. None of the
sampled water supply wells (SW-1, SW-2, SW-4, and SW-5) contained detectable compounds.
Monitoring well MW-3 was not sampled due to the placement of a modular building over the manhole,
and MW-17 had a damaged casing.

An additional groundwater monitoring event conducted by Progress in June 2012 identified LNAPL in four
wells (MW-2, MW-4, MW-8, and MW-14). Laboratory analysis showed seven wells (MW-1, MW-6, MW-
11, MW-12, MW-13, MW-15, and MW-19) contained at least one compound above GCLs. Five wells
(MW-5, MW-7, MW-9, MW-10, and DMW-1) contained at least one compound above 2L Standards, and
four wells (MW-16, MW-18, MW-20, and MW-21) contained detectable compounds below 2L Standards.
None of the sampled water supply wells (SW-1, SW-2, SW-4, and SW-5) contained detectable
compounds.

ATC conducted a groundwater monitoring event in July 2014 which indicated LNAPL in one well (MW-4).
Laboratory analysis showed 11 wells (MW-1, MW-2, MW-5, MW-6, MW-8, MW-11, MW-12 MW-13, MW-
14, MW-15, and MW-19) contained at least one compound above GCLs. None of the sampled water
supply wells (Supply Well, SW-1, SW-3, SW-4, and SW-6) contained detectable compounds.

On June 3, 2015 and July 16, 2015, Cardno, Inc. (Cardno) conducted a ground-penetrating radar (GPR)
assessment to investigate for a potential heating oil UST at the site. Cardno conducted a visual inspection
for evidence of fill ports or vents and used a cart-mounted GPR system to conduct a subsurface
investigation around the perimeter of the existing building and in the vicinity of the former classroom
building. The GPR equipment identified the former gasoline and diesel UST pits along the southeast and
southwest sides of the former Amity Hill Grocery building. The GPR investigation did not identify any
additional UST pits, tanks, or lines that may be associated with a heating oil UST.

ATC conducted a limited groundwater monitoring event in June 2015 which indicated LNAPL in one well
(MW-4) and a sheen in one well (MW-14). Laboratory analysis showed three (MW-2, MW-5, and MW-6)
of the sampled wells contained at least one compound above GCLs. Water supply well SW-1 did not
contain detectable compounds. Power to the on-site Supply Well had been disconnected and the well
could not be sampled as proposed.

ATC conducted a limited, pre-surfactant injection groundwater monitoring event in March 2018 which
indicated LNAPL in six wells (MW-2, MW-11, MW-12, MW-13, MW-14, and MW-15). Wells MW-4 and
MW-6 did not contain sufficient water to be sampled and well MW-17 was dry. Laboratory analysis
showed well MW-1 contained at least one compound above GCLs.

ATC subcontracted Redox Tech, LLC (Redox) to conduct a BioSolve® Activator™ surfactant injection
pilot test at the site from March 19 through March 22, 2018. A total of 34 borings were advanced on the
eastern side of the former Amity Hill Grocery building, in the vicinity of the former gasoline UST basin. A
total of 12 borings, located in the vicinity of MW-1 and MW-14 (closest to the former USTs), were
advanced to 40 feet below ground surface (bgs), with injection performed at 2.5-foot intervals between 10
feet and 40 feet bgs. The injection interval in the 12 borings was intended to extend from the approximate
bottom of the former USTs to the water table. A total of 22 additional borings were advanced to 41 feet
bgs, with injection performed at 2.5-foot intervals between 38.5 feet and 41 feet bgs. The injection interval
in the 22 borings was intended to be within the smear zone.

ATC subcontracted Zava Industrial, Inc. to conduct a five day MMPE event from March 26 through March
30, 2018. Monitoring wells MW-1, MW-4, MW-13, and MW-14 were used as extraction points during the
MMPE event. The four wells were gauged prior to the event, and LNAPL was identified in well MW-13 at
a thickness of 0.18 feet. The remaining wells did not contain LNAPL. Approximately 2,707 gallons of
petroleum-contact water were recovered during the MMPE event. LNAPL was not observed in the tanker
following recovery activities. Approximately 473.60 gallons of VOCs as vapor were calculated to have
been recovered during the event. At the conclusion of the MMPE event, monitoring wells MW-1, MW-4,
MW-13, and MW-14 were gauged for depths to product and water. No measurable LNAPL was detected
in the monitoring wells during post-MMPE event gauging activities.

ATC conducted a post-surfactant injection groundwater monitoring event in May 2018, which indicated
LNAPL in four wells (MW-2, MW-8, MW-12, and MW-13). Well MW-4 did not contain sufficient water for
sample collection and well MW-6 was dry. Well MW-17 was damaged and could not be gauged or sampled.
The remaining site monitoring wells were sampled and analyzed for VOCs. Wells within the pilot surfactant
injection area (MW-11, MW-14, and MW-15) were also analyzed for methylene blue active substances
(MBAS). Detectable concentrations of MBAs were not reported in wells MW-11, MW-14, and MW-15.
Laboratory analysis showed wells MW-1, MW-5, MW-11, MW-14, MW-15, and MW-19 contained at least
one compound above GCLs. Well MW-1, which was straddled by two injection points, indicated
substantial contaminant decreases post-injection event. Wells MW-11, MW-14, and MW-15 indicated a
phase change from LNAPL during pre-injection gauging to high dissolved contaminant concentrations
indicative of LNAPL during post-injection monitoring. Other wells did not indicate substantial contaminant
decreases following the surfactant injection, did not contain sufficient liquid to gauge or sample, or were
not located in the vicinity of the limited pilot test area.

ATC conducted a limited groundwater monitoring event in November 2018, which included monitoring
wells MW-1, MW-4, MW-11, MW-12, MW-13, and MW-14. The event indicated LNAPL in MW-1 and MW-
13. Laboratory analysis showed monitoring wells MW-4, MW-11, MW-12, and MW-14 contained at least
one compound above GCLs.

ATC conducted a groundwater monitoring event in November 2019, which included monitoring wells MW-
1, MW-3, MW-5, MW-7, MW-10, MW-12, MW-13, MW-15, MW-16, MW-18, MW-19, MW-20, MW-21, MW-
22, and DMW-1 and water supply wells WSW-1, WSW-2, and Supply Well. The event indicated LNAPL in
MW-2, MW-4, MW-11, and MW-14, and a thin layer of LNAPL was observed in MW-6. Laboratory analysis
showed monitoring wells MW-1, MW-5, MW-13, and MW-15 contained at least one compound above
GCLs.

On January 21, 2021, ATC gauged liquid levels in the site wells, sampled two water supply wells (WSW-1
and Supply Well), and sampled seven monitoring wells (MW-5, MW-7, MW-10, MW-12, MW-13, MW-22,
and DMW-1). Monitoring well MW-17 was damaged and therefore not included in this monitoring event.
The water samples were analyzed for volatile organic compounds (VOCs). ATC also installed a petroleum
product absorbing sock in monitoring well MW-15. Laboratory analysis showed monitoring wells MW-5,
MW-7, MW-12, MW-13, MW-22 and DMW-1 contained constituents above the 2L standards, and
monitoring wells MW-12 and MW-13 contained constituents above the GCLs. MW-15 contained
measurable LNAPL.

3.3 Site and Regional Geology
According to the Geologic Map of North Carolina, dated 1985, the property lies within the Piedmont
Physiographic Province, in the Charlotte Belt, within an area of fine-grained biotite gneiss, which is a
crystalline metamorphic rock. In most areas, the upper Piedmont subsurface consists of unconsolidated
residual soil, variously known as residuum, saprolite, or partially weathered rock (PWR) that has
developed from in-place weathering of the underlying metamorphic bedrock. The residual soils vary in
consistency and depth based on local conditions. Bedrock can be found at depths ranging from the
surface as outcrops down to greater than 100 feet in areas of easily weathered rock types. Sites near
streams and rivers in the Piedmont may also contain alluvium deposited during flood events.

ATC Project No. SLC0667703 NCDEQ State Lead Program
Boring logs from the November 1994 letter report by Terraine Environmental Services indicated that the
site subsurface consisted of red clay with high organic content in the upper approximately 5 feet bgs;
followed by brownish silt or clayey silt with mica from approximately 5 ft bgs to a boring termination depth
of 42 feet bgs. In March 2000, monitoring well DMW-1 was installed to a depth of 65 feet bgs, and
bedrock was not encountered. Bedrock was also not encountered during advancement of borings for
other monitoring wells at the site.

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. Since 1999,
groundwater levels have been approximately 30 to 40 feet below ground sourface (ft-bgs), with a range of
approximately 10 feet. 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 gauging of site wells, groundwater flow across the site
is to the north-northeast.

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. Most modern water supply wells in the Piedmont consist of a casing set through
the residual soils into the upper bedrock followed by an open borehole into the bedrock where water
bearing fractures were encountered during the drilling.

4.0 GROUNDWATER CHARACTERIZATION
4.1 Water Supply Wells
On October 13, 2022, ATC collected a water supply well sample from water supply well Supply Well. ATC
attempted to collect a sample from water supply well SW-1, however the property owner denied access.
The water 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 Laboratory
(Pace) in Huntersville, North Carolina. The water supply well samples were analyzed by SM 6200B for
VOCs. Laboratory analysis did not identify detectable concentrations of VOCs in the water supply well
sample. Recent and historical water supply well analytical results are summarized in Table 2. Field notes
and photographs from the sampling event are included in Appendix A. The laboratory analytical report
for the water supply well sample is included in Appendix B.

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 noted that the samples were received and
analyzed within correct holding times. 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 method blank and laboratory control sample (LCS) data results were
also provided for each analytical method and a Matrix Spike (MS) and Matrix Spike Duplicate (MSD) was
completed by the lab to determine if any bias could be introduced into the results by the sample matrix.
MS/MSD results were outside QC limits for several constituents; however the batches were still accepted
by the lab based on LCS recovery being within QC limits. ATC also collected a field blank during the

groundwater monitoring event for the analysis using SM 6200B, and no VOCs were detected. 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.

4.2 Groundwater Levels
On October 13, 2022, ATC measured the depth to liquid (groundwater and LNAPL) using an oil/water
interface probe (Table 3). Historically, LNAPL was detected in monitoring wells MW-1, MW-2, MW-4,
MW-6, MW-8, and MW-11 through MW-15. LNAPL was detected in MW-4 and MW-11 (0.24 feet in both
wells) during this sampling event. Following the measurement of liquid levels, new absorbent socks were
installed in MW-4 and MW-11. Following the removal of the LNAPL absorbent socks from wells MW-4
and MW-11, ATC contracted Haz~Mat Environmental to remove and dispose of the socks. A copy of the
manifest is included in Appendix C.

A groundwater elevation contour map depicting the groundwater surface and the projected groundwater
flow direction is presented in Figure 4. Historical depth to groundwater and LNAPL, and groundwater
elevation data are presented in Table 3. Depth to water at the site ranged from 36.90 feet bgs in MW-5 to
36.82 feet bgs in MW-12. Groundwater flow is projected to be to the north-northeast with a gradient of
approximately 0.029. Field notes from the October 13, 2022 groundwater monitoring event are presented
in Appendix A.

4.3 Groundwater Quality
On October 13, 2022, ATC collected groundwater samples from monitoring wells MW-1, MW-2, MW-3,
MW-7, MW-9, MW-12, MW-13, MW-15, MW-16, and DMW-1. A three-volume well purge was
implemented prior to groundwater sample collection to ensure a representative sample was collected.
Wells that did not contain adequate water to conduct a three-volume purge were allowed to recharge for
one hour prior to sampling (MW-1 and MW-3). Upon completion of purging activities, water quality
parameters were measured in each well (Table 4). The water samples were collected in laboratory-
supplied, preserved containers; entered into chain-of-custody control; placed on ice; and delivered to
PACE for analysis. The groundwater samples were analyzed by SM 6200B for VOCs. The analytical
report is included in Appendix B.

Analytical results from the October 13, 2022 monitoring event are summarized in Table 5. Historical
analytical results are shown in Table 6. The analytical results indicated the following:

 Concentrations of benzene and EDB) exceeded the GCLs in the following monitoring wells: MW-1,
MW-2, MW-12, MW-13, and MW-15. The concentration of 1,2-DCA also exceeded the GCL in MW-
2; and
 Concentrations of VOCs exceeded the 2L Standards in the following monitoring wells: MW-1, MW-2,
MW-3, MW-7, MW-12, MW-13, MW-15, and DMW-1.

Figure 5 through Figure 7 depict dissolved-phase isoconcentration contour maps for benzene, EDB, and
1,2-DCA, respectively.

At the request of NCDEQ, an evaluation of the approximate dimensions of the VOC plume was
conducted. The table below shows the approximate areas of the GCL and 2L Standard exceedances in
square feet (SF) from approximately five years ago (5/9/2018) to recent (10/13/2022):

Date 2L Exceedance Area (SF) GCL Exceedance Area (SF)
5/9/18 14,470 6,080
10/13/22 13,700 6,140

The VOC plume dimension evaluation and recent and historical sampling results for the shallow perimeter
monitoring wells indicate that the VOC plume is stable, with the only exceedances of the 2L Standards in
the perimeter wells indicated in the downgradient well MW-22. Wells without historical LNAPL also
indicated stable or decreasing VOC concentrations. Wells with historical LNAPL continue to indicate
fluctuating VOC concentrations. VOCs in the deep well DMW-1 exceed the 2L Standards, and appear to
be relatively stable based on the last four sampling events.

The QA and QC measures and conditions applicable to the water supply well monitoring, as discussed in
section 4.1, also apply to the monitoring well sampling.
5.0 CONCLUSIONS AND RECOMMENDATIONS
On behalf of the Trust Fund Branch of the UST Section, ATC has completed a Groundwater Monitoring
Report documenting monitoring well sampling activities conducted on October 13, 2022 for Amity Hill
Grocery, located at 1495 Ostwalt Amity Road, Cleveland, Iredell County, North Carolina. ATC gauged
liquid levels in the site wells, sampled one water supply well (Supply Well), and sampled ten monitoring
wells (MW-1, MW-2, MW-3, , MW-7, MW-9, MW-12, MW-13, MW-15, MW-16, and DMW-1).

Site conditions based on the recent and prior assessment activities are summarized below:

 Five drinking water supply wells are located within 1,000 feet of the source area, with water supply
wells Supply Well and SW-1 located within 250 feet of the source area. Municipal water is not
available to the area;
 No surface water bodies are located within 500 feet of the source area;
 VOCs were not detected in the water supply well sample (Supply Well);
 LNAPL was detected in monitoring wells MW-4 and MW-11 (0.24 feet LNAPL in both);
 Concentrations of benzene and DB) exceeded the GCLs in the following monitoring wells: MW-1,
MW-2, MW-12, MW-13, and MW-15. The concentration of 1,2-DCA also exceeded the GCL in MW-
2;
 Concentrations of VOCs exceeded the 2L Standards in the following monitoring wells: MW-1, MW-2,
MW-3, MW-7, MW-12, MW-13, MW-15, and DMW-1; and
 Depth to water at the site ranged from 35.32 feet below top of casing (ft-toc) in MW-9 to 38.20 ft-
toc in MW-15. Groundwater flow is projected to be to the north-northeast.
 An evaluation of the approximate dimensions of the VOC plume was conducted in order to further
demonstrate that the VOC plume is stable over time. The approximate areas in square feet (SF)
of GCL and 2L standard exceedances have remained relatively stable over the past five years.

The VOC plume dimension evaluation and recent and historical sampling results for the shallow perimeter
monitoring wells indicate that the VOC plume is stable, with the only exceedances of the 2L Standards in
the perimeter wells indicated in the downgradient well MW-22. Wells without historical LNAPL also
indicated stable or decreasing VOC concentrations. Wells with historical LNAPL continue to indicate
fluctuating VOC concentrations. VOCs in the deep well DMW-1 exceed the 2L Standards, and appear to
be relatively stable based on the last four sampling events.

Based on the findings of the recent monitoring event and the historical remedial actions taken, ATC
recommends the following:

 Quarterly installation and/or replacement of LNAPL absorbing socks in the applicable wells,
including wells that are expected to have measurable LNAPL with water table fluctuation;
 Consider conducting MMPE events, enhanced with air sparging (new deeper wells in the LNAPL
plume area) and air injection in selected existing shallow wells;
 Abandonment and replacement of MW-17 as a shallow side-gradient monitoring point; and
 Semi-annual groundwater monitoring events and groundwater monitoring following enhanced
MMPE events.

TOC Elevations based on arbitrary on-site benchmark
NM = Not Measured
LNAPL = Light Non-Aqueous Phase Liquid
When free product is present, the following formula is used to calculate the groundwater elevation:
Groundwater Elevation = TOC - (Water Level Measurement + LNAPL Thickness x 0.8581)
Groundwater elevations measured on 3/19/18 and 3/22/18 were collected pre- and post-surfactant injection.
Groundwater elevations measured on 3/26/18 and 3/30/18 were collected immediately pre- and post-MMPE event.
* Groundwater elevations were collected 20 minutes post-MMPE event on 3/30/18

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.
TNI - The NELAC Institute.
