2.0 EXECUTIVE SUMMARY
ATC Associates of North Carolina, P.C. (ATC) has completed a Monitoring Report documenting a
groundwater monitoring event conducted March 15-16, 2023, at L&TA Enterprises. The report has
been completed based on a February 13, 2023, 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 was performed as part of the
State Lead Contract # N122019A between the NCDEQ and ATC.

The former petroleum UST system at the site released product to the subsurface prior to its
removal on August 30, 2007. The former UST system consisted of two 10,000-gallon gasoline
USTs, one 8,000-gallon gasoline UST, and associated piping and dispensers. During removal
activities, two 3,000-gallon gasoline USTs were removed from the site. A new UST system,
consisting of one 12,000-gallon gasoline UST, one 3,000-gallon gasoline UST, and one 10,000-
gallon diesel UST, was installed in September 2007. The USTs were removed on December 1,
2020. The site is currently vacant with the above ground structures removed from the site and the
site is secured with fencing and locked gates with access provided by Charlotte-Douglas
International Airport staff.

As part of TA-03, ATC conducted a groundwater monitoring event on March 15-16, 2023 with
analyses of the samples for volatile organic compounds (VOCs).

The findings from the groundwater monitoring event indicate the following:

 ATC gauged eighteen accessible monitoring wells for the depth to water and light non-
aqueous phase liquid (LNAPL) on March 15, 2023. LNAPL was detected in MW-6 with
thickness of 0.1 feet. MW-19 was unable to be located. Groundwater levels were above the
screen in ten of the shallow wells with no LNAPL detected.

 On March 15-16, 2023, groundwater samples were collected from seventeen monitoring
wells: MW-1 through MW-5, MW-7 through MW-10, MW-15 through MW-18, MW-20, MW-
21, TW-1, and TW-2.

 The Gross Contamination Levels (GCLs) were exceeded for benzene in wells MW-1 , MW-
2, MW-4, MW-5, MW-7, MW-8, MW-10, MW-17, MW-18, MW-20 and MW-21; for
Naphthalene in MW-17; for tert-amyl alcohol (TAA) in wells MW-2, MW-4, MW-5, MW-7,
MW-8, MW-10, MW-18, and MW-21; for tert-Butyl Alcohol in wells MW-2, MW-7, MW-
10, and MW-18; and for ethanol in well MW-17.

 The 15A NCAC 2L .0202 groundwater quality standards (2L Standards) were exceeded
for one or more VOCs in all wells sampled.

Historically, LNAPL has been detected in shallow wells MW-2, MW-6, MW-7, MW-8, MW-10,
MW-15, MW-17, MW-18, MW-20, and MW-21. LNAPL has not been detected in shallow wells
MW-1, MW-3, MW-4, MW-5, MW-9, MW-16, and MW-19 (last measured November 2021).
Compared to the November 2021 samplings results, VOC concentrations have generally
increased in wells MW-1, MW-4, MW-5, MW-8, MW-10, MW-16, MW-17, and MW-21; and,
decreased in wells MW-7, MW-15, MW-20, TW-1, and TW-2. VOC concentrations have
fluctuated substantially in wells with historical LNAPL.

Over time, measured LNAPL thicknesses in site monitoring wells have been significantly
reduced compared to initial levels, indicating recovery efforts has have been successful in
reducing the amount of LNAPL in the subsurface. However, note that when groundwater levels
are above the well screens, the presence and thickness of LNAPL is not likely representative of
actual condition. Seven of the wells sampled contained total concentrations of benzene,
ethylbenzene, toluene, and xylenes above 65,000 micrograms per liter (µg/L), suggesting the
presence of LNAPL.

Based on the findings presented above, ATC recommends the following depending on funding
availability from the State Lead Trust Fund:

 Based on the quantity of LNAPL removed during the MMPE/AS events, conduct annual
or semi-annual MMPE and monitoring events.

 Consider conducting High Resolution Site Characterization (HRSC) study to further
evaluate the horizontal and vertical extent of LNAPL.

3.0 SITE DESCRIPTION
3.1 Site Characterization
ATC, under contract to the NCDEQ, provided environmental consulting services at the L&TA
Enterprises site, which is located at 6020 Wilkinson Boulevard in Charlotte, Mecklenburg County,
North Carolina. Figure 1 depicts the site on a topographic map. The site formerly operated an
active service station and convenience store as Airport Express. The site is currently vacant,
secured with fencing and locked gates, and all above ground structures have been removed from
the site. Based on historical information, up to 24 private water supply wells may exist within 1,500
feet of the source area, but many may be abandoned and the properties connected to municipal
water. Based on Mecklenburg County’s Well Information System, there are no active potable wells
within 1,000 feet of the source area. Potable water is provided to the area by the Charlotte Water.

3.2 Site Background
Five USTs, located east of the product dispenser islands, were removed from the site on August
30, 2007. The former UST system consisted of two 10,000-gallon gasoline USTs, one 8,000-gallon
gasoline UST, and associated piping and dispensers. During removal activities, two 3,000-gallon
gasoline USTs were also observed and removed from the site. Soil impact was identified during
the UST system removal, with total petroleum hydrocarbons (TPH) as gasoline at a maximum
observed concentration of 4,140 milligrams per kilogram (mg/kg). The highest concentrations of
TPH as gasoline were generally observed in the area of the product dispensers. The USTs
showed minor surface corrosion with no visible holes. As part of initial abatement action
activities, approximately 730 tons of impacted soil was removed from the site in September
2007. Maximum excavation depths of approximately 17 feet and 13 feet below grade were
achieved in the former UST basin and product dispenser area, respectively. Post-excavation
soil samples indicated residual contaminant concentrations above Maximum Soil Contaminant
Concentrations (MSCCs) in the UST basin, but below MSCCs in the product dispenser area.
Information regarding the UST removal and overexcavation activities are summarized in the
UST Closure, 20 day, and Initial Abatement Action Report, dated November 5, 2007, by
Paragon Environmental Consulting.

In September 2007, one 12,000-gallon gasoline UST, one 3,000-gallon gasoline UST, and one
10,000-gallon diesel UST were installed at a location west of the product dispenser islands. A
new product dispenser island was installed in the location of the former dispenser island, south
of the store building.

Subsequent assessment activities, conducted through October 2015, were performed by
Environmental Compliance Services of North Carolina, P.C. A Phase I and II Limited Site
Assessment (LSA) report was completed for the site on April 10, 2008. Soil samples (SB-1 and
SB-2) were collected during installation of Type II groundwater monitoring wells MW-1 and MW-
2, which were located in the former UST basins. Soil impact above the Soil-to-Water MSCCs
were observed. Dissolved impact above 2L Standards were observed in the two monitoring
wells. Additional assessment consisted of installation of Type II groundwater monitoring wells
MW-3, MW-4, and MW-5 in locations north and south of the former UST basins. Dissolved
contaminant concentrations were identified in wells MW-4 and MW-5 above 2L Standards, and
VOCs were not observed in the sample collected from well MW-3. Based on site and area
surface topography, the general groundwater flow direction appeared to be towards the
southeast. A total of seven active and six inactive water supply wells were identified within 1,500
feet of the site, including one inactive water supply well on the release source property.
Municipal water was provided to the site and surrounding area by the City of Charlotte. The
closest surface bodies were observed as an unnamed perennial creek located approximately
400 feet south-southeast from the site (mapped by Mecklenburg County to be approximately
760 feet from the site), a pond located approximately 1,500 feet southeast from the site, and an
unnamed creek located approximately 1,400 feet west-northwest from the site.

A Comprehensive Site Assessment (CSA) report was completed for the site on November 30,
2008. Six soil borings (CSA-1 through CSA-6) were advanced in the areas of the former UST
basins, former piping, and product dispenser islands. Five Type II groundwater monitoring wells
(MW-6 through MW-10) and one Type III groundwater monitoring well (TW-1) were also
installed. Soil assessment activities indicated soil impact above the Soil-to-Water and
Residential MSCCs, with the greatest concentrations in the area around the southern fuel
dispenser island and the center of the former UST basin. Dissolved concentrations above 2L
Standards were identified in wells MW-1, MW-4, MW-5, MW-9, and TW-1. Measurable LNAPL,
with a maximum thickness of approximately four feet, was observed in wells MW-2, MW-6, MW-
7, MW-8, and MW-10. The report noted that six water supply wells within 1,500 feet of the site
remained active, and the closest active water supply well was located approximately 720 feet
southeast of the site. Updated information indicated a groundwater flow direction towards the
southwest; however substantial LNAPL accumulation in site monitoring wells may have
depressed and locally affected hydrology. No significant vertical hydraulic gradient was
observed between wells MW-2 and TW-1. Rising-head slug tests indicated hydraulic
conductivities of 7.587 x 10-5 centimeters per second (cm/sec) and 4.103 x 10-5 cm/sec for Type
II wells MW-4 and MW-5, respectively, and a hydraulic conductivity of 4.947 x 10-4 cm/sec for
Type III well TW-1. A mean hydraulic conductivity was used to calculate a groundwater flow
velocity of 7.3 feet per year.

One, 8-hour Aggressive Fluid/Vapor Recovery (AFVR) event was conducted at the site on
January 28, 2009. Immediately prior to the event, LNAPL, at an approximate maximum
thickness of 11 feet, was observed in wells MW-2, MW-6, MW-7, MW-8, and MW-10. The AFVR
event utilized wells MW-2, MW-4, MW-6, MW-7, MW-8, and MW-10 as extraction points. Liquid

levels collected approximately 20 minutes following the AFVR event indicated measurable
LNAPL, at an approximate maximum thickness of eight feet, in wells MW-2, MW-6, MW-7, MW-
8, and MW-10. A calculated total of approximately 11.91 pounds (1.98 gallons) of petroleum as
vapor was removed from the extraction points during the event. Approximately 71 gallons of
LNAPL were recovered from the extraction points. Approximately 23 days following the AFVR
event, LNAPL thicknesses had rebounded to, or exceeded, the pre-AFVR event levels.

An updated water supply well survey was conducted in April 2009. Twenty-four suspect water
supply wells were visually observed and occupants were interviewed where available. It
appeared that many water supply wells had been abandoned due to nearby Charlotte Douglas
International Airport expansion activities.

A Free Product Recovery Report dated May 13, 2009, detailed hand-bailing of site wells that
contained free product (MW-2, MW-6, MW-7, MW-8, and MW-10) and conducting product bail-
down tests by measuring product recovery rates at wells MW-6 and MW-10 (wells with the
greatest measured product thicknesses). A total of 36.5 gallons of product were bailed from site
monitoring wells. Wells MW-6 and MW-10 indicated average product recovery rates of 0.0196
and 0.02 gallons per minute, respectively, during the first five minutes of each test.

One, 5-day Mobile Multi-Phase Extraction (MMPE) event was conducted at the site from
November 16 through 20, 2009. Wells MW-2, MW-6, and MW-7, which were utilized as
extraction points for the event, contained LNAPL immediately prior to the MMPE event, at a
maximum thickness of approximately 11 feet. A calculated total of approximately 1295.34
pounds (210.56 gallons) of petroleum as vapor was removed from the extraction points during
the event. Approximately 340 gallons of LNAPL and 4,833 gallons of petroleum-contact water
were recovered from the extraction points. Liquid levels collected following the MMPE event
indicated measurable LNAPL in wells MW-6 and MW-7, at an approximate maximum thickness
of 0.04 feet. Well MW-2 did not contain measurable LNAPL following the MMPE event.
Approximately one month following the MMPE event, LNAPL levels rebounded in the extraction
wells. A report receipt letter from the NCDEQ, dated February 4, 2010, indicated a calculated
total of 9,650 gallons of LNAPL are present at the site based on calculated true thicknesses, so
passive skimming would be more cost-effective than active recovery in the form of AFVRs
because the November 2009 MMPE event only recovered approximately 550 total gallons of
petroleum product as vapor and liquid.

A CSA Addendum Report was completed on January 22, 2010, which detailed additional
assessment activities including installation of Type II groundwater monitoring wells MW-11
through MW-14 and Type III groundwater monitoring wells TW-2 and TW-3. Groundwater flow
direction was estimated using only wells containing no measurable LNAPL and was determined
to be generally towards the southwest. An average horizontal hydraulic gradient of 0.0011
feet/foot was calculated at the site. Downward vertical hydraulic gradients of 0.026 and 0.036
feet/foot were calculated between wells MW-4/TW-2 and MW-12/TW-3, respectively. The report
indicated a groundwater flow velocity at the site ranging from 1.47 to 2.73 feet per year.
Groundwater from the new wells and existing well MW-A was sampled as part of the
assessment activities. Wells MW-A, MW-11, TW-2, and TW-3 contained contaminant
concentrations above 2L Standards.

Additional assessment activities, including installation of Type II groundwater monitoring wells
MW-15 through MW-19, were conducted in May and June 2010 to continue contaminant

delineation at the site. Groundwater flow direction was again determined to be towards the
southwest, with an average horizontal hydraulic gradient of 0.0088 feet/foot. Downward vertical
hydraulic gradients of 0.001981 and 0.007203 feet/foot were calculated between wells MW-
4/TW-2 and MW-12/TW-3, respectively. Wells MW-15 and MW-16 contained contaminant
concentrations above 2L Standards. Wells MW-17 and MW-18 each contained approximately
nine feet of LNAPL during monitoring activities.

Groundwater monitoring wells MW-20 and MW-21 were installed at the site in August 2010.
Wells MW-20 and MW-21 subsequently contained measurable levels of LNAPL, at thicknesses
of approximately seven feet and 0.08 feet, respectively. Additional groundwater monitoring
activities were not conducted beyond August 2010 by the responsible party, L&TA Enterprises
LLC.

On October 29, 2013, a Site Check Activities letter report was completed due to a failed spill
bucket tightness test at the regular gasoline UST at the site. Two soil borings were advanced
with a hand auger at locations adjacent to the UST basin for soil sample collection.
Concentrations of TPH as gasoline were not reported above method detection limits in the two
soil samples collected.

Groundwater monitoring wells MW-11 through MW-14 and TW-3 were abandoned in July 2014
due to expansion of the Charlotte Douglas International Airport.

A request for bid had been prepared for an active LNAPL skimming system at the site in July
2010. However, the responsible party did not proceed with installation of the system, citing
financial constraints. In August 2013, the NCDEQ required hand-bailing of wells with LNAPL
thicknesses greater than 0.01 feet. Hand-bailing was completed approximately every other
week between May and October 2015, and a total of approximately 277.14 gallons of LNAPL
were recovered during that period.

The L&TA Enterprises site was recommended for cleanup by the NCDEQ under the State Lead
Program on March 21, 2016, because L&TA Enterprises LLC remained recalcitrant with regards
to installation of the proposed LNAPL recovery system despite enforcement proceedings and a
settlement that was reached in March 2015. The site was accepted into the State Lead Program
on March 29, 2016.

On February 13 and 14, 2019, groundwater samples were collected from monitoring wells MW-1,
MW-3, MW-4, MW-5, MW-9, MW-16, MW-19, MW-20, MW-21, TW-1, and TW-2. LNAPL was
measured in MW-2, MW-6, MW-7, MW-8, MW-10, MW-15, MW-17, and MW-18. The results of the
sampling event indicated dissolved contaminant concentrations in wells MW-1, MW-3, MW-4,
and MW-5 had increased substantially since the most recent sampling event which occurred in
2009. ATC concluded that based on historical data over time, measured LNAPL thicknesses in
site monitoring wells have significantly reduced compared to initial levels, indicating recovery
efforts may have been successful in reducing the amount of free-phase product in the
subsurface.

ATC conducted two 96-hour MMPE events at the site between February 10 and 14, 2020 and
between February 17 and 21, 2020. Calculated effluent airflow rates and the vapor concentration
readings from the vacuum truck indicated that an estimated 851.69 pounds (138.44 equivalent
gallons) of petroleum hydrocarbons were recovered as vapor during the MMPE event. The

L&TA Enterprises

7
MMPE event removed approximately 4,994 gallons of total fluids, including an estimated 30
gallons of LNAPL.

On February 24 & 25, 2020 ATC gauged the accessible monitoring wells for depth to water and
light non-aqueous phase liquid (LNAPL), and collected samples monitoring wells: MW-1, MW-2,
MW-3, MW-4, MW-5, MW-9, MW-16, MW-19, TW-1, and TW-2. Wells MW-6, MW-7, MW-8, MW-
10, MW-15, MW-17, and MW-18 contained LNAPL and were not sampled. The Gross
Contamination Levels (GCLs) were exceeded for benzene in wells MW-1, MW-3, MW-4, and MW-
5, and for tert-amyl alcohol (TAA) in wells MW-4 and MW-5. The 15A NCAC 2L .0202
groundwater quality standards (2L Standards) were exceeded for one or more VOCs in wells
MW-1, MW-2, MW-3, MW-4, MW-5, MW-9 and TW-1.

On September 1, 2020, the property was purchased by the City of Charlotte, and Charlotte-
Douglas International Airport is managing the property. The USTs and dispensers were
removed on December 1, 2020

ATC conducted one 96-hour MMPE event at the site between October 11 and 15, 2021.
Calculated effluent airflow rates and the vapor concentration readings from the vacuum truck
indicated that an estimated 4,307 pounds (700 equivalent gallons) of petroleum hydrocarbons
were recovered as vapor during the MMPE event. The MMPE event removed approximately
9,790 gallons of total fluids, including an estimated 16 gallons of LNAPL.

On November 5, 2021 ATC gauged the accessible monitoring wells for depth to water and light
non-aqueous phase liquid (LNAPL), and collected samples from monitoring wells: MW-1
through MW-10, MW-15 through MW-21, TW-1, and TW-2. LNAPL was not detected during the
groundwater sampling event. The Gross Contamination Levels (GCLs) were exceeded for
benzene in wells MW-1, MW-2, MW-3, MW-4, MW-5, MW-6, MW-7, MW-8, MW-10, MW-15,
MW-17, MW-18, MW-20 and MW-21; for tert-amyl alcohol (TAA) in wells MW-5, MW-6, MW-8,
MW-10, and MW-18; and for ethanol in well MW-17. The 15A NCAC 2L .0202 groundwater
quality standards (2L Standards) were exceeded for one or more VOCs in all wells sampled
excluding well MW-19.

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 lies in the Charlotte Belt of the Piedmont Physiographic Province of North
Carolina. The rock type in this area has been identified as metamorphosed granitic rock, diorite,
and gabbro. 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.

Boring logs from historical assessment activities conducted at the site indicate that the
subsurface consists of residual tan silty fine sand fill material to a depth of approximately four feet
below grade, underlain by reddish tan, tan to red, and red sandy, silty clay and clayey silt to a

L&TA Enterprises
April 10, 2023

depth of approximately 65 feet below grade. Bedrock was not encountered during installation of
Type III monitoring well TW-1 to a depth of approximately 65 feet below grade.

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 gauging of the
monitoring well network, groundwater flow across the site is generally toward the south-
southwest. Depth to groundwater in the overburden aquifer at the site has historically ranged
from approximately 17 to 34 feet below grade. Some reporting inconsistency exists regarding
groundwater velocity at the site but, based on historical reports, a groundwater velocity ranging
from approximately 1.47 to 7.3 feet/year has been estimated.

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
4.1 Groundwater Levels
On March 15-16, 2023, groundwater monitoring was conducted for the site monitoring well
network. Figure 2 depicts a site map with well locations. Well MW-A and MW-19 could not be
located during the March 2023 monitoring activities. An oil/water interface probe was used to
measure liquid levels from the top-of-well casing (TOC) at the site wells. Groundwater
elevations were then calculated based on TOC elevations, which are referenced to an arbitrary
datum of 100.00 feet. LNAPL was detected in MW-6 at a thickness of 0.10 feet.

A groundwater flow map was not generated due to inconsistent groundwater elevations which may
be due to groundwater levels being above the screened interval of several of the wells.
Historically, groundwater flow has been reported to be to the south-southwest.

Depth to groundwater and elevation data are summarized in Table 1. Groundwater elevations
are presented on Figure 3. Field notes from the March 15-16, 2023, groundwater monitoring
event are presented in Appendix A.

4.2 Groundwater Quality
On March 15-16, 2023, groundwater samples were collected from monitoring wells MW-1 through
MW-5, MW-7 through MW-10, MW-15 through MW-18, MW-20, MW-21, TW-1, and TW-2.

A three-volume well purge was implemented prior to groundwater sample collection to ensure a
representative sample was collected. Upon completion of purging activities, water quality
parameters were measured in each well. Water quality parameters recorded prior to sample
collection 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, located in Huntersville, North Carolina. The groundwater samples were
analyzed by Standard Method (SM) 6200B for VOCs including oxygenates. The analytical report is
included as Appendix D.

Groundwater analytical results from the March 15-16, 2023, monitoring event are summarized in
Table 3. Historical groundwater analytical results are shown in Table 4. The groundwater analytical
results were compared to 2L Standards and GCLs.

The findings from the monitoring event indicate the following:

 The Gross Contamination Levels (GCLs) were exceeded for benzene in wells MW-1 , MW-
2, MW-4, MW-5, MW-7, MW-8, MW-10, MW-17, MW-18, MW-20 and MW-21; for
Naphthalene in MW-17; for tert-amyl alcohol (TAA) in wells MW-2, MW-4, MW-5, MW-7,
MW-8, MW-10, MW-18, and MW-21; for tert-Butyl Alcohol in wells MW-2, MW-7, MW-
10, and MW-18; and for ethanol in well MW-17.

 The 2L Standards were exceeded for one or more VOCs in all wells sampled.

Compared to the November 2012 samplings results, VOC concentrations have generally
increased in wells MW-1, MW-4, MW-5, MW-8, MW-10, MW-16, MW-17, and MW-21; and,
decreased in wells MW-7, MW-15, MW-20, TW-1, and TW-2.

Figure 4 depicts VOCs exceeding the 2L Standards.

As part of ATC’s quality assurance and quality control (QA and QC) measures, a data review of the
laboratory report was conducted. 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 SM 6200B. The
laboratory fortified blank (LFB) and laboratory control sample (LCS) data results were also
provided for SM 6200B. A field blank was also collected during the groundwater monitoring event.
Laboratory analysis of the field blank indicated no constituents above method detection limits.
Refer to the laboratory report in Appendix D 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 has completed a Monitoring
Report documenting remediation and groundwater monitoring activities for the L&TA
Enterprises site, located at 6020 Wilkinson Boulevard, Charlotte, Mecklenburg County, North
Carolina.

As part of TA-03, ATC conducted a groundwater sampling event on March 15-16, 2023.

The findings from the groundwater monitoring event indicate the following:

 ATC gauged the accessible monitoring wells for the depth to water and LNAPL thickness
on March 15, 2023. LNAPL was detected in MW-6 with thickness of 0.1 feet. MW-19 was
unable to be located. Groundwater levels were above the screen in eleven of the wells with
no LNAPL detected.

 On March 15-16. 2023, groundwater samples were collected from seventeen monitoring
wells MW-1 through MW-5, MW-7 through MW-10, MW-15 through MW-18, MW-20, MW-
21, TW-1, and TW-2. LNAPL was detected in MW-6 during the groundwater sampling
event.

 The Gross Contamination Levels (GCLs) were exceeded for benzene in wells MW-1 , MW-
2, MW-4, MW-5, MW-7, MW-8, MW-10, MW-17, MW-18, MW-20 and MW-21; for
Naphthalene in MW-17; for tert-amyl alcohol (TAA) in wells MW-2, MW-4, MW-5, MW-7,
MW-8, MW-10, MW-18, and MW-21; for tert-Butyl Alcohol in wells MW-2, MW-7, MW-
10, and MW-18; and for ethanol in well MW-17.

 The 15A NCAC 2L .0202 groundwater quality standards (2L Standards) were exceeded
for one or more VOCs in all wells sampled.

Compared to the November 2012 samplings results, VOC concentrations have generally
increased in wells MW-1, MW-2, MW-4, MW-5, MW-8, MW-10, MW-16, MW-17, and MW-21;
and, decreased in wells MW-7, MW-15, MW-20, TW-1, and TW-2.

Over time, measured LNAPL thicknesses in site monitoring wells have been significantly
reduced compared to initial levels, indicating recovery efforts may have been successful in
reducing the amount of LNAPL in the subsurface. Seven of the wells sampled contained total
concentrations of benzene, ethylbenzene, toluene, and xylenes above 65,000 µg/L, suggesting
the presence of LNAPL.

Based on the findings presented above, ATC recommends the following depending on funding
availability from the State Lead Trust Fund:

 Based on the quantity of LNAPL removed during the MMPE/AS events, conduct annual
or semi-annual MMPE and monitoring events.

 Consider conducting an HRSC study to further evaluate the horizontal and vertical
extent of LNAPL.

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 EPA
Method 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.
