2.0 EXECUTIVE SUMMARY

The Apple Auto/McBroom Rental site is located at 3341 North Roxboro Street,
Durham, Durham County, North Carolina. One 1,100-gallon gasoline underground
storage tank (UST) was previously operated at the site and was removed in 1995.
The associated petroleum release was discovered during an investigation performed
at the McBroom Rental Property.
The purpose of this report is to document the latest groundwater sampling event.
On June 20, 2023, CATLIN Engineers and Scientists (CATLIN) personnel measured
groundwater at approximately 12.6 feet deep across the site. Light non-aqueous
phase liquid (LNAPL; aka free-phase product) was measured in MW-8 at 0.15 feet thick. Groundwater samples from 11 monitoring wells and one water supply well
(WSW-2) were collected. The samples were submitted for laboratory analysis of
volatile organic compounds (VOCs) per Standard Method (SM) 6200B plus ethylene
dibromide (EDB), methyl tert-butyl ether (MTBE), and diisopropyl ether (DIPE).
Laboratory results did not indicate any dissolved petroleum constituents above their
respective laboratory reporting limits in the samples from MW-1, MW-6, and MW-11.
Multiple VOCs were detected in the MW-2A, MW-3, MW-5, and MW-12 samples at
concentrations greater than those established in Title 15A of the North Carolina
Administrative Code, Subchapter 2L, Section .0202 Groundwater Quality Standards (2L GWQS), but below the Gross Contaminant Levels (GCL). The sample from
MW-4 had a concentration of tetrachloroethylene (chlorinated solvent) above the 2L
GWQS.

Contaminant concentrations appear to have increased in samples from monitoring wells MW-5 and MW-12 since the previous sampling event in August 2021, while
those in MW-2A and MW-3 have fluctuated. The concentrations in VE-1 have
decreased to below 2L GWQS.

The sample from WSW-2 contained a concentration of MTBE above its 2L GWQS. DIPE, tetrachloroethylene, and toluene were also detected above the laboratory
method detection limits.

CATLIN recommends to:
• Conduct a surfactant injection event followed by a mobile multi-phase
extraction (MMPE) event to reduce the LNAPL concentrations and dissolved
phase contamination.
• Perform a sampling event approximately 30 days after the MMPE event.
• Determine if the parcel owner for WSW-2 is willing to connect to municipal
water and have the well abandoned.
3.0 SCOPE OF SERVICES
The scope of services for this report was performed in general accordance with
CATLIN proposal number 221141.01P, dated June 6, 2023. Services were
authorized by the North Carolina Department of Environmental Quality’s (NCDEQ’s)

4.0 SITE HISTORY AND CHARACTERIZATION

The Apple Auto/McBroom Rental site is located at 3341 North Roxboro Street,
Durham, Durham County, North Carolina (Figures 1 and 2). Summarized available historical sampling and gauging data are provided in Appendix A. Site photographs
are presented in Appendix B.

4.1 UST OWNER AND OPERATOR INFORMATION
TTM Properties, LLC owned the UST system historically operated on the site,
which was used for retail petroleum sale prior to 1973. Available information
regarding UST owners/operators is presented on Table 1.
4.2 UST INFORMATION
One 1,100-gallon gasoline UST was historically operated to serve a retail fuel
pump. It was removed in 1995, along with the associated piping and pump
system. Installation and operation dates are unknown (ECS, 2020).
Available UST system information is presented in Table 1 and the
approximate former UST basin location is illustrated on Figure 3.

4.3 CONTAMINANT SOURCE INVENTORY
During a Phase II Environmental Site Assessment conducted by GAI
Consultants in 1993 on the neighboring McBroom Property, monitoring well
NMW-1 was installed in the vicinity of Apple Auto UST. Laboratory analysis
of the groundwater sample from NMW-1 revealed petroleum constituents
which could be attributed to the UST (ECS, 2020).

NCDEQ; 10915_Apple Auto-McBroom Rental CATLIN Engineers and Scientists
CATLIN Project No. 221141 4 August 2023
During tank closure activities conducted in 1995, soil samples also revealed
petroleum contamination. LNAPL was found in NMW-1 at this time (ECS, 2020).

4.4 SITE CHARACTERISTICS

The property is currently owned by TTM Properties, LLC, and previously operated as a National Pawn retail store. The site consists of a retail building
and surrounding asphalt parking lot with small patches of grass on the
northern end of the property.
4.5 OWNERS AND OCCUPANTS OF ADJOINING/NEARBY PROPERTIES AND LAND USE

Properties in the site vicinity are a combination of commercial retail stores
and private residences. All the adjacent properties, and those across Acker
Avenue to the northwest and across North Roxboro Street to the northeast, are commercial retail properties. Single family homes are located to the west
of the site.

It should also be noted that there are several UST and/or above ground
storage tank (AST) incidents within 1,000 feet of the subject site. The incident numbers are listed below and the locations are illustrated on Figure 2.
• UST Incident Number 6592
• UST Incident Number 39572
• UST Incident Number 33612
• UST Incident Number 22877
• AST Incident Number 92738

4.6 RECEPTOR INFORMATION

Conducting a receptor survey was outside the scope of this monitoring event. A review of historical files available on the NCDEQ Waste Management
Online Database (aka Laserfiche) indicates the most recent receptor survey
update was conducted in October 2010 by Pyramid Environmental and
Engineering.
According to previous reports, municipal water is available to the site vicinity.
Two water supply wells have been identified within 1,000 feet of the source
area. No surface water has been identified within 1,000 feet of the source
area (ECS, 2018). Water supply well WSW-1 is located approximately 830
feet southeast of the site, in an upgradient direction, and is used for irrigation purposes. Water supply well WSW-2 is located approximately 590 feet
downgradient of the subject site and was identified as a potable well. As of
August 2020, the owners of WSW-2 drink bottled water, but use the well for
washing clothes and bathing.

NCDEQ; 10915_Apple Auto-McBroom Rental CATLIN Engineers and Scientists
CATLIN Project No. 221141 5 August 2023
Potential receptors are illustrated on Figure 2 and receptor information is
shown on Table 2.
4.7 PREVIOUS INVESTIGATIONS AND REMEDIAL ACTIVITIES

The McBroom property provided evidence there had been a release on this
site, and tank removal activities in 1995 confirmed the presence of petroleum impacted soils. Following tank closure activities, monitoring well MW-1 was
installed in the former UST basin. Monitoring wells MW-2 through MW-9 were
installed between 1996 and July 2010 by Pyramid. In July 2010, a receptor
survey update was conducted. In October 2010, soil samples obtained from
the multiple locations revealed numerous contaminants present above soil-to-groundwater and residential maximum soil contaminant concentration
levels (MSCCs). Recovery well RW-1 was installed in May 2011 by Pyramid
and VE-1 is only known to be installed before 2013. Monitoring wells MW-10
through MW-13 were installed in February 2016 by ECS (ECS, 2020). Details
about well construction are included in Table 3.
Aggressive fluid vapor recovery (AFVR) events were conducted in 1996 and
2006 using MW-1 as an extraction point, and in November 2017 using MW-8
as an extraction point. Mobile multi-phase extraction (MMPE) events were
conducted at this site in May 2011, January 2013, and August 2013. All of the above recovery events were conducted in response to discovery of
LNAPL at the site. Historically, LNAPL has been measured in MW-1, MW-8,
and MW-9. ECS deployed a LNAPL absorbent boom in MW-8 in 2018 which
has been used to extract several ounces of LNAPL on an annual basis since
installation. Since 2016, O-Sox devices have been deployed in MW-2A, MW-3, MW-4, MW-5, MW-8, MW-10, MW-11, MW-12, and/or RW-1 (ECS,
2020).

The monitoring wells on-site and water supply wells identified in the vicinity of
the site have been sampled periodically since 2010. GCL exceedances have been revealed in samples taken from MW-8, and once in MW-2A. All other
monitoring wells have had 2L GWQS exceedances of targeted contaminants
except for MW-6. However, since 2018, no samples collected from MW-1,
MW-10, or MW-11 have contained any contaminants in excess of the 2L
GWQS. While samples from WSW-1 have never contained petroleum constituents in excess of 2L GWQS, samples from WSW-2 have contained
concentrations of MTBE and 1,2-dichloroethane in excess of 2L GWQS
(ECS, 2020).

In 2018, ECS conducted a geophysical survey of the site including a ground penetrating radar (GPR) survey to determine if there were any anomalies
indicative of remaining USTs and product piping. The survey found no
evidence of further USTs or associated piping (ECS, 2020).

On March 3, 2020, ECS conducted hydraulic conductivity tests on the shallow aquifer in monitoring wells MW-2A, MW-4, and MW-12. Based on the

NCDEQ; 10915_Apple Auto-McBroom Rental CATLIN Engineers and Scientists
CATLIN Project No. 221141 6 August 2023
results, they concluded that the existing non-compliant plume of petroleum
related compounds is not expected to migrate more than 50 feet from MW-2A over a period of 100 years (ECS, 2020).

CATLIN conducted a groundwater sampling event in August 2021. LNAPL
was measured in monitoring well MW-8 at 0.88 feet thick. Laboratory results
did not indicate any petroleum constituents above their laboratory reporting limits in the sample from MW-6. Multiple VOCs were detected in the MW-2A,
MW-3, MW-5, MW-12, and VE-1 samples at concentrations above 2L GWQS
but below GCL. The sample from MW-4 had a concentration of
tetrachloroethylene (chlorinated solvent) above the 2L GWQS. The
contaminant concentrations in samples from all wells except MW-3 had increased since the August 2020 monitoring event (CATLIN, 2021).

On July 12, 2022, CATLIN oversaw a Laser Induced Fluorescence (LIF)
investigation performed by Dakota Technologies (Dakota). Following the
investigation, Dakota prepared a High-Resolution Site Characterization (HRSC) Report that concluded the LNAPL is generally located at a depth of
nine to ten feet BLS (CATLIN, 2022).

Summarized available historical sampling and gauging data are provided in
Appendix A.
5.0 REGIONAL AND SITE GEOLOGY AND HYDROGEOLOGY

5.1 SOIL AND BEDROCK
As defined in the Geologic Map of North Carolina, published by the North
Carolina Department of Natural Resources and Community Development
(1985), the site lies within the Piedmont physiographic province.

The site is within the Durham-Sanford subsection of the Triassic basin and underlain by the Diabase formation. According to the 1985 Geologic Map of
North Carolina, gray to black dikes are common.

Specific soil information is not available due to the lack of boring logs on-file
in Laserfiche.
5.2 HYDROGEOLOGY

Groundwater - The 2020 Visual Hydrogeologic Framework – North Carolina
Hydrogeological Database did not identify sufficient boreholes near the site in order to draw a cross-section.

Surface Water – No surface water has been found within 1,000 feet of the
site (ECS, 2020).

NCDEQ; 10915_Apple Auto-McBroom Rental CATLIN Engineers and Scientists
CATLIN Project No. 221141 7 August 2023
6.0 SITE ASSESSMENT INFORMATION
CATLIN conducted field activities on June 20, 2023 in accordance with the approved
TA. Upon arrival at the site, potential hazards were evaluated before beginning field
work and are documented on an electronic Job Hazard Analysis (JHA) form. The
JHA form is included in Appendix C. Photographs from the site visit are included in
Appendix B.
CATLIN personnel gauged and collected groundwater samples for laboratory
analysis per SM 6200B from 11 monitoring wells (MW-1, MW-2A, MW-3, MW-4,
MW-5, MW-6, MW-11, MW-12, MW-13, RW-1, and VE-1). Monitoring well MW-8
contained 0.15 feet of LNAPL. Well locations and site features are shown on Figure 3 and well construction details are presented on Table 3.

6.1 GAUGING DATA

Depth to groundwater at this site can change from year to year with recent historical levels varying between 10.67 feet below land surface (BLS) at
MW-6 in 2021 to 19.31 feet BLS in MW-11 in 2018. Historically, groundwater
flow has been identified as moving in the north-northwestern direction (ECS,
2020).
During the June 2023 event, CATLIN personnel measured depth to water
using an electronic water interface probe. To prevent cross contamination,
the probe and cabling were decontaminated according to manufacturer’s
recommendations between use in each well. Gauging data were recorded on
an electronic groundwater sampling form using a tablet device. Gauging procedures were performed in general accordance with North Carolina
Department of Environmental and Natural Resources (NCDENR), and
NCDEQ Guidelines, and Environmental Protection Agency (EPA) Region 4
Operating Procedures.
Depth to water ranged from 2.55 feet below top of casing (BTOC) (MW-1) to
15.36 feet BTOC (MW-11). The depths to water measured in monitoring well
MW-1 and recovery well RW-1 were above their respective screened
intervals. LNAPL was measured in MW-8 at a thickness of 0.15 feet. The
water level at VE-1 was above the well shield and no well cap could be placed. Based on groundwater elevations calculated for this monitoring
period, the groundwater flow direction is north-northwest.

Monitoring well gauging results for events conducted by CATLIN are
presented in Table 3. Groundwater elevation is illustrated on Figure 4 and groundwater sampling forms are provided in Appendix C.

6.2 SAMPLING DATA

Following gauging, the monitoring wells and water supply well were sampled in general accordance with NCDEQ Guidelines and U.S. EPA Region 4

NCDEQ; 10915_Apple Auto-McBroom Rental CATLIN Engineers and Scientists
CATLIN Project No. 221141 8 August 2023
Operating Procedures. Prior to obtaining representative groundwater
samples, each monitoring well was purged by removing a minimum of three well volumes using a new, disposable bailer. The water supply well was
purged by allowing the spigot to run for approximately 15 minutes.
Groundwater field parameter data were measured at one-minute intervals
using an In-Situ Aqua TROLL 600 Multiparameter Sonde (Aqua TROLL). The
Aqua TROLL measured specific conductivity, pH, oxidation reduction-potential (ORP), dissolved oxygen, and temperature, which were recorded
utilizing the VuSitu mobile application (version 1.17.12). Groundwater
parameter data were transferred from the VuSitu mobile application to the
electronic groundwater sampling forms. Copies of the groundwater sampling
forms are available in Appendix C.
After purging activities, a groundwater sample was collected from each well
and poured directly into appropriate laboratory-provided, pre-preserved
glassware, labeled, and placed on ice in an insulated cooler. A laboratory-
provided trip blank was maintained in the cooler for the duration of the sampling event.

The groundwater samples a laboratory-provided trip blank were submitted to
Con-Test Analytical Laboratory (Certification NC 652 and NC-DW 25703) in
East Longmeadow, Massachusetts, under proper chain of custody (COC) protocol and analyzed per SM 6200B (including EDB, MTBE, and DIPE).
The laboratory analytical data and COC are included in Appendix D.

6.3 SUMMARY OF GROUNDWATER INFORMATION
Historically, samples from monitoring wells MW-2A, MW-5, MW-8, and
MW-12 have contained the highest petroleum constituent concentrations.
LNAPL has been detected at this site in MW-1, MW-8 and MW-9. During the
previous sampling event conducted by CATLIN (August 2021), MW-8
contained LNAPL, and samples from MW-2A, MW-3, MW-5, MW-12, and VE-1 contained at least one petroleum constituent concentration above its 2L
GWQS, but below GCLs. Historically, GCL exceedances have been detected
in MW-2A, MW-8 and MW-9. Summarized available historical sampling and
gauging data are provided in Appendix A.
The latest groundwater sampling laboratory results for SM 6200B analysis
are summarized in Table 4. Historical results for events conducted by
CATLIN are in Table 5. Monitoring well sample analytical results are
presented on Figure 5 and the estimated horizontal extent of benzene is
illustrated on Figure 6. Water supply well sample analytical results are shown on Figure 7. A copy of the complete laboratory report and COC
documentation are in Appendix D.

NCDEQ; 10915_Apple Auto-McBroom Rental CATLIN Engineers and Scientists
CATLIN Project No. 221141 9 August 2023
Monitoring Wells During the June 2023 monitoring event, 11 monitoring well samples (MW-1,
MW-2A, MW-3, MW-4, MW-5, MW-6, MW-11, MW-12, MW-13, RW-1, and
VE-1) were collected and submitted for analysis via SM 6200B (including
EDB, MTBE, and DIPE). Laboratory analysis did not detect any constituents
above the laboratory reporting limits in the samples from MW-1, MW-6, and MW-11. No analyte concentrations were detected above GCL in any of the
monitoring well samples. Analytical results reported the following constituents
at concentrations above their 2L GWQS in samples MW-2A, MW-3, MW-4,
MW-5, and MW-12:
• MW-2A: benzene, naphthalene, toluene, and total xylenes;
• MW-3: benzene, 1,2-dichloroethane, 1,2-dichloropropane, and
naphthalene;
• MW-4: tetrachloroethylene (chlorinated solvent); and
• MW-5: benzene, 1,2-dichloropropane, ethylbenzene, naphthalene, n-
propylbenzene, toluene, 1,2,4-trimethylbenzene, and total xylenes;
• MW-12: benzene, 1,2-dichlorobenzene, 1,4-dichlorobenzene, ethylbenzene, naphthalene, 1,2,4-trimethylbenzene, and total
xylenes.

Water Supply Well

A groundwater sample was obtained from one water supply well (WSW-2).
The following analytes were detected above the laboratory method detection
limits: DIPE, MTBE, tetrachloroethylene, and toluene. MTBE was also
detected above its 2L GWQS. No other targeted analytes were detected above their laboratory reporting limits in the water supply well sample.

Trip Blank

One laboratory-provided trip blank sample was submitted for analysis per SM 6200B (including EDB, MTBE, and DIPE). No targeted analytes were
detected in the trip blank sample.

6.4 EVALUATION OF ASSESSMENT INFORMATION

Extent of Contamination

Several petroleum constituents were detected above their respective 2L
GWQS in samples from MW-2A, MW-3, MW-5, and MW-12.
Tetrachloroethylene (chlorinated solvent) was above its 2L GWQS in the MW-4 sample. Monitoring well MW-8 contained LNAPL at the time of
sampling. A summary of groundwater sample analytical results for the
monitoring wells are illustrated on Figure 5 and the estimated horizontal
extent of benzene is illustrated on Figure 6. Water supply well sample
analytical results are presented on Figure 7.

NCDEQ; 10915_Apple Auto-McBroom Rental CATLIN Engineers and Scientists
CATLIN Project No. 221141 10 August 2023
The highest contaminant concentrations have historically been reported in
samples from MW-2A, MW-5, MW-8, and MW-12. Analytical results from the previous monitoring event (August 2021) revealed several petroleum
constituents above 2L GWQS in the samples obtained from the previously
listed monitoring wells. The contaminant concentrations in samples from
MW-5 and MW-12 have increased since the previous monitoring event, while
those in MW-2A and MW-3 have fluctuated. However, the concentrations in VE-1 have decreased to below 2L GWQS.

Cleanup Levels Achieved

Soil – Soil samples obtained in 2010 indicate that numerous contaminants above soil-to-groundwater and Residential MSCCs.

Groundwater – Groundwater contaminant concentrations are above 2L
GWQS, but below GCL at the site.

LNAPL – LNAPL (0.15 feet thick) was measured in MW-8 during this
monitoring period.

7.0 CONCLUSIONS AND RECOMMENDATIONS

Conclusions

Groundwater monitoring findings for this period are summarized below:
• Eleven monitoring wells (MW-1, MW-2A, MW-3, MW-4, MW-5, MW-6, MW-11, MW-12, MW-12, MW-13, RW-1, and VE-1) and one water supply
well (WSW-2) were sampled.
• LNAPL (0.15 feet thick) was measured in monitoring well MW-8.
• No analyzed compound concentrations were detected above the laboratory
reporting limit in the samples from MW-1, MW-6, and MW-11.
• Several petroleum constituents above their 2L GWQS were reported in the
samples from MW-2A, MW-3, MW-5, and MW-12, but none were found above GCL limits.
• Tetrachloroethylene (chlorinated solvent) was above its 2L GWQS in the
MW-4 sample.
• The sample from water supply well WSW-2 was found to contain MTBE
above 2L GWQS. It should be noted that there is another UST Incident and
an AST Incident downgradient of this site that could potentially be
contributing to the contaminants detected in WSW-2.
• The groundwater flow direction was found generally to be to the north-northwest.

NCDEQ; 10915_Apple Auto-McBroom Rental CATLIN Engineers and Scientists
CATLIN Project No. 221141 11 August 2023
Recommendations
CATLIN recommends to:
• Conduct a surfactant injection event followed by a MMPE event to reduce the
LNAPL concentrations and dissolved phase contamination.
• Perform a sampling event approximately 30 days after the MMPE event.
• Determine if the parcel owner for WSW-2 is willing to connect to municipal
water and have the well abandoned.

Wide RPD limits established for difficult compound.
#Data exceeded client recommended or regulatory level
Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
No results have been blank subtracted unless specified in the case narrative section.
FLAG/QUALIFIER SUMMARY
Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
J
Laboratory fortified blank/laboratory control sample recovery and duplicate recovery are outside of control limits.
Reported value for this compound is likely to be biased on the low side.
L-04
Either laboratory fortified blank/laboratory control sample or duplicate recovery is outside of control limits, but
the other is within limits. RPD between the two LFB/LCS results is within method specified criteria.
L-07
Elevated reporting limit due to high concentration of target compounds.RL-11
