1.0 BACKGROUND AND GENERAL SITE INFORMATION
The Amoco #9 site is located at 7810 Lyles Lane in Concord, Cabarrus County, North Carolina. The site is
currently identified with Cabarrus County parcel identification number 4589-92-4798. The property is owned
by the Bermuda Company, and the UST systems are currently owned and operated by Monroe Oil Company
(Monroe) as a convenience store and gasoline station. The McDonalds Corporation also operates a
McDonald's restaurant on the subject property. The site location is depicted as Figure 1 and Figure 2,
included in Appendix A.
Monroe currently operates two UST systems at the subject site. UST #1 is a 25,000-gallon compartmentalized
UST, which contains regular gasoline (15,000 gallon) and premium gasoline (10,000 gallon). UST #2 is a
3,000 single compartment UST, which contains diesel fuel.
According to Monroe representatives, during the night of September 25, 2009, a school activity bus collided
with Dispenser #1 located at the site. The collision resulted in damage to the dispenser system, which
resulted in the release of gasoline. The gasoline was not released to the ground surface; instead, the fuel was
released to secondary containment sumps associated with the UST system. The driver of the vehicle that
collided with the fuel dispenser left the scene of the incident; however, the incident was witnessed by other
individuals at the site and the owner of the vehicle was identified. Based on information provided by EMC
Insurance Companies, the incident eyewitness identified the school activity bus as being from Mount Zion
Christian Academy in Durham, North Carolina.
During the incident, the released fuel entered the containment sumps beneath the fuel dispenser, and back -
flowed into the secondary containment sumps located atop the USTs. Approximately 304 gallons of fuel were
recovered from the secondary containment sumps; however, at least one of the containment sumps (atop the
USTs) was cracked, which allowed the fuel to be released to the backfill within the UST basin.
Following the completion of incident response activities, Monroe noted a discrepancy of approximately 296
gallons between the apparent volume of recovered fuel and the UST inventory. Monroe then contacted their
insurance provider (EMC Insurance Companies). EMC contacted Highlands Environmental Solutions, Inc.
(HES) on October 20, 2009, to provide environmental services to investigate the incident and to assess for
residual petroleum impacts at the site. On behalf of Monroe Oil Company, HES prepared and submitted a
UST-61 Release Notification Form to the NCDEQ for the incident on October 21, 2009.
HES conducted a site check investigation, which included the collection of soil samples from several borings
around the damaged fuel dispenser and UST basin. Field and laboratory data collected during soil sampling
and subsequent analysis indicated the presence of petroleum -impacted soil/backfill material inside the UST
basin. HES reported the results of the investigation in a Site Check Report submitted to the North Carolina
Department of Environmental Quality (NCDEQ) on January 5, 2010.
Following review of the Site Check Report, the NCDEQ sent a Notice of Regulatory Requirements (NORR)
dated January 20, 2010, to Monroe Oil Company. HES personnel mobilized to the field on March 31, 2010, to
address the issues presented within the NORR. Additional soil borings were advanced around the perimeter
of the UST basin, at each submersible pump secondary containment sump, and under the previously
damaged fuel dispenser. Soil samples collected during subsequent assessment activities were submitted for
laboratory analysis of gasoline range organics (GRO), and diesel range organics (DRO). Selected soil
samples collected around the perimeter of the UST basin were analyzed for volatile organic compounds
(VOCs), and volatile petroleum hydrocarbons (VPH).
During subsequent site assessment activities, HES also installed one groundwater monitoring well (MW-1)
immediately downgradient of the UST basin, and collected a groundwater sample for analysis of VOCs, VPH,
and lead. Free -product was detected on the water surface at a thickness of 0.09 feet in the groundwater
monitoring well. VOCs and VPH were also detected in monitoring well MW-1 at concentrations above the
North Carolina Groundwater Quality Standard (NCGWQS). VOCs were also detected in monitoring well MW-1
at concentrations above Gross Contamination Levels for Groundwater. GRO and DRO were detected in soil
samples collected during environmental assessment activities at concentrations greater than the North

Groundwater Monitoring Report - July 2019

Carolina State Action Limit in six, and three of the soil samples respectively. VOCs and/or semi -volatile
organic compounds (SVOCs) were detected at concentrations greater than their respective Soil -to -
Groundwater, Residential, and Industrial/Commercial North Carolina Maximum Soil Contaminant
Concentrations (MSCCs) in four soil samples.
On August 18, 2010, HES installed three additional groundwater monitoring wells (MW-2, MW-3, MW-4), and
collected a groundwater sample from each well for analysis of VOCs, VPH, and lead. Free -product was not
detected on the water surface of MW-2, MW-3, or MW-4. VOCs were detected in MW-2 and MW-3 at
concentrations greater than their respective North Carolina Administrative Code Subchapter 2L Groundwater
Quality Standards (NCAC 2L Standards). VPH and lead were not detected in MW-2, MW-3, and MW-4 at
concentrations greater than their respective NCAC 2L Standards.
On February 23 and 24, 2011, HES installed five additional groundwater monitoring wells (MW-1D, MW-5,
MW-6, MW-7, and MW-8), and replaced monitoring well MW-1 with a two-inch EPA type II well. HES collected
a groundwater sample from each well for analysis of VOCs, VPH, and lead.
Also, on February 23 and 24, 2011, HES advanced four soil borings near the dispenser island adjacent to the
UST basin (SB-1, SB-2, SB-3, and SB-4). One soil boring (SB-5) was advanced near the Northwest corner of
the UST basin, and one soil boring (SB-6) was advanced near the Southwest corner of the UST basin. HES
collected six soil samples (SB-1, SB-2, SB-3, SB-4, SB-5, and SB-6) for laboratory analysis of VOCs and
VPH.
To date, two active liquid petroleum hydrocarbons (LPH) recovery events have been performed at the site.
The first recovery event was a manual (i.e. bailing) event performed on MW-1 on October 13, 2010. During
this event, LPH was measured at a thickness of 0.07 feet. Approximately 22 gallons of liquid (product and
groundwater) was recovered from monitoring well MW-1 during this event. All recovered liquids were
containerized in a 55-gallon drum at the site. Following completion of the event, the thickness of LPH in the
well demonstrated no measurable change.
A second LPH recovery event (Aggressive Fluid Vapor Recovery - AFVR) was performed at the site on July
14, 2011. During the AFVR event, HES utilized a vacuum truck to recover liquids and vapor from the well.
The wellhead was sealed to maximize vacuum pressures in the well, which enhanced the recovery of
volatilized gasoline (i.e. vapors). During the recovery event, HES depressed the water table surface local to
the well, to maximize LPH recovery. During the AFVR event, HES personnel monitored liquid levels in nearby
monitoring wells, as well as, temperature, airflow, relative humidity, and the total concentration of VOCs in the
effluent air stream from the vacuum truck. Monitoring well MW-1 was evacuated of liquid and the AFVR event
was performed for approximately 8 hours. A total of 1,239 gallons of liquid (free product and groundwater)
were removed from monitoring well MW-1. The purpose of this recovery event was to aggressively remove
most of the liquid from the well, and to determine if LPH returned to the well following the event.
On October 26 and 27, 2011, HES installed two additional groundwater monitoring wells (MW-9 and MW-10).
HES collected a groundwater sample from each well at the site for laboratory analysis of VOCs, VPH, and
lead.
A two-inch passive skimmer was installed in MW-1 on April 11, 2012. At that time product thickness was
measured at 0.08 feet prior to the installation of the passive skimmer. HES personnel have monitored the
passive skimmer monthly since it was installed. The amount of liquid and product located in the collection
chamber of the passive skimmer recorded each month is as follows:
■ May 25, 2012 - Approximately 8.0 inches of total liquid (product and water) were removed
and approximately 0.1 inch of liquid in the chamber appeared to be product.
■ June 14, 2012 - Approximately 4.0 inches of total liquid (product and water) were removed
and approximately 1.5 inches of the liquid appeared to be product.

On September 17, 2012, HES installed an additional groundwater monitoring well (MW-11). HES collected a
groundwater sample from each well at the site for laboratory analysis of VOCs, VPH, and Lead.
On February 20, 2019, HES installed three groundwater monitoring wells MW-1 R and MW-1 DR, (replacement
wells for MW-1 and MW-1 D, respectively) s and MW-12. A site diagram depicting the locations of monitoring
wells on site is depicted as Figure 3.
Adjacent properties consist of commercial land uses and do not show evidence of impact by the subject
release. All properties within 1500 feet of the site utilize municipal water supplies for potable water. Three
water supply wells (used for irrigation purposes) are located within 1500 feet of the release area. The closest
irrigation well is located approximately 90 feet Northwest of the UST basin, and has been out of service for
approximately seven years. The other two irrigation wells are located more than 1000 feet to the Southeast of
the site. Surface water bodies are not located within 250 feet of the release area.

2.0 SITE INVESTIGATION
2.1 Monitoring Well Installation and Site Survey
Monitoring well MW-1 was installed on April 1, 2010. Probe Technologies (Probe) was subcontracted for well
installation. The well installation location is depicted on Figure 3. MW-1 was installed to a total depth of 30
feet below the ground surface and was constructed as a one -inch well. The well was constructed of Schedule
40 PVC casing and manufactured well screen (25 feet). A sand filter pack was installed to a depth
approximately two feet above the top of the well screen. The remaining annulus was backfilled with a neat
Portland cement grout, and the well was completed with a flush -mount steel cover and locking cap.
Monitoring wells MW-2, MW-3, and MW-4 were installed on August 18, 2010. HES again subcontracted
Probe for drilling services. The well installation locations are depicted on Figure 3. The borings for these
wells were advanced using the same methodology and extended to depths of 20 feet below ground surface.
The monitoring wells were constructed of two-inch Schedule 40 PVC manufactured well screen (15 feet) and
casing. A sand filter pack was installed to a depth approximately one foot above the top of the well screens.
The remaining annulus was backfilled with concrete, and the wells were completed with a flush -mount steel
covers and locking caps. Additional details regarding well construction are presented as Table 1, included in
Appendix B.
Monitoring wells MW-5, MW-6, MW-7, and MW-8 were installed between February 22, 2011, and February24,
2011. HES again contracted Probe for drilling services. The well installation locations are depicted on Figure
3. The borings for these wells were advanced using the same methodology and extended to depths of 20 feet
below ground surface, with the exception of monitoring well MW-1 D, that extended to a depth of 40 feet below
ground surface. Monitoring wells MW-5, MW-6, MW-7, and MW-8 were constructed of two-inch Schedule 40
PVC manufactured well screen (15 feet) and casing. A sand filter pack was installed to a depth approximately
one foot above the top of the well screens. The remaining annulus was backfilled with a neat Portland cement
grout, and the wells were completed with a flush -mount steel covers and locking caps.
On February 23, 2011, monitoring well MW-1 was replaced and installed as two-inch well. Monitoring well
MW-1 was installed to a depth of 20 feet below ground surface and constructed of two-inch Schedule 40 PVC
manufactured well screen (15 feet) and casing. A sand filter pack was installed to a depth approximately one
foot above the top of the well screen. The remaining annulus was backfilled with concrete, and the wells were
completed with a flush -mount steel cover and locking cap.
Monitoring well MW-1 D was installed as an EPA Type III telescoping well on February 23, 2011. The well was
constructed of thirty feet of four -inch Schedule 40 PVC surface casing and grouted in -place. The grout was
allowed to cure for twelve hours prior to installing the one -inch Schedule 40 PVC. The one -inch PVC was
installed to forty feet below grade, and MW-1 D was constructed with five feet of Schedule 40 pre -packed well
screen. A sand filter pack was installed to a depth approximately one foot above the top of the well screen. A
bentonite seal was installed atop the well screen to a depth of twenty-five feet below grade. The remaining
annulus was backfilled with a neat Portland cement grout, and the well was completed with a flush -mount steel
cover and locking cap.
Monitoring wells MW-9 and MW-10 were installed on October 26, 2011. HES again contracted Probe for
drilling services. The well installation locations are depicted on Figure 3. The borings for these wells were
advanced using the same methodology and extended to depths of 20 feet below ground surface. Monitoring
wells MW-9 and MW-10 were constructed of two-inch Schedule 40 PVC manufactured well screen (15 feet)
and casing. A sand filter pack was installed to a depth approximately one foot above the top of the well
screens. The remaining annulus was backfilled with a neat Portland cement grout, and the wells were
completed with a flush -mount steel covers and locking caps.
Monitoring well MW-11 was installed on September 17, 2012. HES again contracted Probe for drilling
services. The well installation location is depicted on Figure 3. The boring for monitoring well MW-11 was
advanced using the same methodology and extended to a depth of 44.0 feet below the ground surface.
Monitoring well MW-11 was constructed of two-inch Schedule 40 PVC manufactured well screen (20 feet) and
casing. A sand filter pack was installed to a depth approximately one foot above the top of the well screens.

The remaining annulus was backfilled with a neat Portland cement grout, and the well was completed with a
flush -mount steel cover and locking cap.
Monitoring wells MW-1 R, MW-1 DR, and MW-12 were installed on February 20, 2019. Wells MW-1 R and MW-
1 DR were replacement wells for monitoring wells MW-1 and MW-1 D (respectively that were previously
damaged. HES again contracted IET for drilling services. The well installation location is depicted on Figure
3. The boring for monitoring well MW-1 R was advanced using the same methodology and extended to a
depth of 20.0 feet below the ground surface. MW-12 was advanced using the same methodology and
extended to a depth of 17.0 feet below the ground surface. Monitoring well MW-1 DR was installed as an EPA
Type III telescoping well on February 20, 2019. MW-1 DR was constructed of forty feet of four -inch Schedule
40 PVC surface casing and grouted in -place. The grout was allowed to cure for twelve hours prior to installing
the two-inch Schedule 40 PVC. The two-inch PVC was installed to thirty-five feet below grade, and MW-1 D
was constructed with five feet of Schedule 40 pre -packed well screen. Monitoring well MW-1 R was
constructed of two-inch Schedule 40 PVC manufactured well screen (20 feet) and casing. Monitoring well MW-
12 was constructed of two-inch Schedule 40 PVC manufactured well screen (17 feet) and casing. A sand filter
pack was installed to a depth approximately one foot above the top of the well screens. The remaining
annulus was backfilled with a neat Portland cement grout, and the well was completed with a flush -mount steel
cover and locking cap.
Following completion of well construction, the depth to liquid in each well was determined using a Testwell
Oil/Water Interface Meter. The well volume was calculated, and the wells were developed by the use of
bailers. All recovered liquids were visually examined for the presence of free -product and/or hydrocarbon
sheens. Free product was not observed in any of the wells on site, and all liquids generated during well
development were discharged to paved areas on the property, in accordance with NCDEQ regulations. The
wells were allowed to recover for two hours before sampling. All monitoring well locations are depicted on
Figure 3.
2.2 Water Level Measurements
The July 2019 groundwater monitoring activities were performed at the site on July 11, 2019. Monitoring well
MW-9 was gauged and sampled on Jul 17, 2019 (the well was not accessible during July 11 sampling event.
During the groundwater monitoring event, monitoring wells MW-7 and MW-8 were found to be damaged and
could be neither gauged nor sampled. The damage appeared to have occurred during site repaving activities.
Depth -to -liquid data were collected from the remaining monitoring wells at the site. An electronic oil -water
interface probe was utilized to collect the depth -to -liquid data, and all depth -to -liquid measurements were
referenced to the top of each well casing. The oil -water interface probe was cleaned between each use, and
the least impacted wells were checked first, while the two most impacted wells were checked last.
Water level data were utilized to create a graphical representation of the water table surface in the surficial
aquifer (Figure 4). Depth -to -liquid and well construction data are summarized on Table 1 (in Appendix B).
2.3 Monitoring Well Sampling
During the July 11, 2019 monitoring event, groundwater samples were collected from monitoring wells MW-
1 R, MW-1 DR, MW-2, MW-3, MW-4, MW-5, MW-6, MW-9 (sampled on July 17, 2019), MW-10, MW-11, and
MW-12. As noted earlier, monitoring wells MW-7 and MW-8 were unable to be sampled during the sampling
event due to apparent damage. Using the depth -to -water and total -well -depth data, the well -volumes of each
monitoring well were calculated, and three times that volume was to be removed prior to sampling each well in
order to collect a current representative groundwater sample. HES personnel used new, non -reactive
sampling gloves, a new dedicated disposable bailer, and new nylon rope in each of the wells during purging.
After removing three well -volumes of water or bailing the wells dry three times (whichever occurred first), the
groundwater samples were collected from each well. To collect the groundwater sample, the dedicated bailer
was carefully lowered to a depth just beneath the water level in the well. The bailer was allowed to fill, and
then the bailer was recovered. The groundwater samples were placed in labeled, pre -preserved, laboratory -
supplied containers, maintained on ice, and transferred to a courier for a North Carolina -certified laboratory
(Con -test Analytical Laboratories — ConTest, NC Certification #652). The courier then shipped the samples

under proper chain -of -custody protocol to the laboratory for analysis of VOCs, by Method 6200D; and VPH by
the MADEP Method.
Laboratory analytical data for groundwater samples collected on July 11, 2019, are summarized on Table 2
and Table 2a. A copy of the complete laboratory analytical data report for the July 2019 sampling event is
included in Appendix C.

3.0 DISCUSSION
The Amoco #9 site is a retail gasoline and convenience store located at 7810 Lyles Lane, in Concord, Cabarrus
County, North Carolina. A petroleum release occurred at the site in September 2009, due to a third -party motor
vehicle colliding with a petroleum dispenser at the site (dispenser #1). The third party has been identified, and
EMC Insurance is investigating the identified third party for insurance coverage.
The subject site is zoned and utilized for commercial use. Adjacent properties are zoned and utilized for
commercial land uses. Underground utilities are located on site. Underground utilities (piping and electrical
lines) associated with the UST systems transect the UST basin at the site. Public utilities observed in the area
of the property included electrical, telephone, cable television and public water and sewer service, however,
these utilities do not transect the petroleum -impacted area of the site.
Surface water bodies are not located within a 250-foot radius of the site. The closest surface water feature is a
drainage ditch situated approximately 360 feet northwest of the UST basin. The property slopes to the south,
therefore, stormwater from the site and adjacent properties would be expected to flow towards the south. The
surface water body was neither impacted nor significantly threatened by the subject release.
The site is not located within a wellhead protection area. One water supply well, formerly used for irrigation
purposes, is located within 250 feet of the UST basin. Based on information provided by the owner of this well,
the well is damaged and not currently in service. No other water supply wells were identified within 1000 feet of
the site. The subject site and all adjacent properties utilize public water supplies for potable water.
Groundwater in the shallow aquifer beneath the site has historically been inferred to flow predominantly toward
the south. However, water level data suggests the water table beneath the Amoco #9 property itself is locally
influenced. This is most likely due to natural and/or manmade structures in the subsurface. Local mounding of
the water table near the UST basin is not considered to be unusual, given the differences between the
hydraulic conductivity and porosity of the UST basin backfill materials, and the native soil at the site.
A total of eleven monitoring wells have been installed at the site, to include eleven EPA Type II), and one EPA
Type III monitoring wells. The most recent groundwater monitoring event was completed on July 11, 2019.
During this event, one groundwater sample was collected from each monitoring well at the site utilizing
disposable bailers, with the exception of MW-7 MW-8 which were damaged. During the most recent monitoring
event, none of the monitoring wells contained any free product.
During the July 2019 monitoring event, several dissolved phase petroleum constituents were detected in site
monitoring wells at concentrations greater than their respective NCAC 2L Standard as follows:
MW-1 R — VOCs
- Benzene at 270 ug/L
- Ethylbenzene at 700 ug/L
- Isopropylbenzene at 98 ug/L
- Naphthalene at 320 ug/L
- n-Propylbenzene at 130 ug/L
- 1,2,4-Trimethylbenzene at 860 ug/L
- Xylenes at 2600 ug/L
- C5-C8 Aliphatics at 2600 ug/L
- C9-C10 Aromatics at 4200 ug/L
MW-1 DR — VOCs
- Acetone at 1200ug/L
- Benzene at 1.3 ug/L
- MTBE at 27 ug/L

• MW-10 — VOcs
- MTBE at 35 ug/L
Historically, the bulk of the dissolved -phase petroleum plume in groundwater beneath the site is situated on the
Amoco #9 site in the vicinity of the initial spill area, with the geometry of the plume being enlarged toward the
South and Southeast. A diagram depicting the benzene and MTBE plumes are included as Figure 5 and 6,
respectively. Additionally, a diagram depicting NCAC 2L Standard exceedances is included as Figure 7.
HES prepared and submitted a Corrective Action Plan (CAP) for this site. This CAP has been reviewed and
approved by the NCDEQ — Mooresville Regional Office. The technology to be utilized at the site is an approved
technology. An agreement with the property owner (The Bermuda Corporation) is being negotiated for the
implementation of the CAP.
HES recommends the following:
• Implementation of the proposed CAP.
• Continued semi-annual groundwater monitoring.
The site has been assigned a "high" risk ranking due to the presence of a former irrigation well within 250 feet
of the source area. This well is out of service, and was sampled during the December 2018 sampling event,
with no detectable concentrations of petroleum hydrocarbons. If this well was properly abandoned, then the
site would qualify as "low" risk, and the incident could receive regulatory closure via a Notice of Residual
Petroleum on the property.

MADEP-VPH-Feb 2018 Rev 2.1
No significant modifications were made to the method. All VPH samples were received preserved properly at pH <2 in the proper containers as specified on the chain -of -custody
form unless specified in this narrative.
Analytical column used for VPH analysis is Restek, Rtx-502.2, 105meter, 0.53mmID, 3um df. Trap used for VPH analysis is Carbopack B/CarboSieveS-III.
The results of analyses reported only relate to samples submitted to the Con -Test Analytical Laboratory for testing.
I certify that the analyses listed above, unless specifically listed as subcontracted, if any, were performed under my direction according to the approved methodologies listed
in this document, and that based upon my inquiry of those individuals immediately responsible for obtaining the information, the material contained in this report is, to the
best of my knowledge and belief, accurate and complete.

FLAG/QUALIFIER SUMMARY
* QC result is outside of established limits.
fi Wide recovery limits established for difficult compound.
$ Wide RPD limits established for difficult compound.
# Data exceeded client recommended or regulatory level
ND Not Detected
RL Reporting Limit is at the level of quantitation (LOQ)
DL Detection Limit is the lower limit of detection determined by the MDL study
MCL Maximum Contaminant 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.
J Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
L-07 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.
RL-11 Elevated reporting limit due to high concentration of target compounds.
5-17 Surrogate recovery is outside of control limits. Data validation is not affected since all associated results are less
than the reporting limit and bias is on the high side.
