Executive Summary
Monitoring Report
January 31, 2020
Page i
The Carolina Fast Mart #4 Pit Stop site is considered a High Risk site assigned groundwater incident
#201 l7 and is located in Cabarrus County, North Carolina. The site currently operates as a BP
petroleum filling station and convenience store. The site does not have an active remedial system
and is monitored via groundwater sampling events that are conducted semi-annually in June and
December, Mobile Multi -Phase Extraction (MMPE) events have been conducted historically prior
to sampling events. The following information pertains to the findings of the December 2019
sampling event(s):
• Free product was not present at the site during this monitoring period and has never been
present in any of the site wells.
• Dissolved phase petroleum constituent compounds were detected in concentrations
above the 15A NCAC 2L Groundwater Standards (2L Standards) in monitoring wells
MW-10B, MW-13, and MW-16.
• The contaminant plume appears to be relatively stable. Constituent concentrations have
overall decreased since the initial September 2013 sampling event.
• The concentration of benzene increased above the 2L Standard in MW-13 since the
previous routine sampling event.
• Diisopropyl ether (IPE) at the site has decreased below 2L Standards.
■ Contaminant Mass has decreased from approximately 3,400 grams in July 2019 to
approximately 1,800 grams in December, 2019.
• Due to no power at the well, WSW-1 was not sampled during the December 2019
sampling event. Also, the owner was not at home during the sampling event.
■ Previous active remediation at the site consisted of soil excavation at the time of the UST
removal. Soil delineation sampling was conducted in association with Comprehensive
Site Assessment (CSA) addendum activities in September 2013. Based on information
presented in the CSA Addendum, soil contamination in the form of benzene only was
found near one former sidewall of the large UST excavation above the Soil -to -
Groundwater (STG) maximum soil contaminant concentration levels (MSCCs) but not
above the Residential MSCCs. No soil contamination was found near the former diesel
UST area above the STG or Residential MSCCS. All four samples collected from
around the smaller UST excavation area exceeded the STG MSCCs for gasoline related
constituents of concern (COCs) but none of these samples exceeded the Residential
MSCCs.

• Shield's project director discussed the site with the current NCDEQ incident manager on
November h, 2019 as follow up to the NCDEQ NO RR letter dated September 24, 2019.
It was determined that two more sampling rounds, after the July 2019 sampling event,
with similar sampling results to the July 2019 results were needed before the site could
be closed with a Notice of Residual Petroleum (NDRP) deed restriction.
Based on the December 2019 sampling results, only one more round of sampling with
similar results should be required before the site can be closed with a Notice of Residual
Petroleum (NORP) deed restriction.

1.0 SITE HISTORY AND CHARACTERIZATION
1.1 Historical Information on Release
Monitoring Report
January 3I, 2020
Page I
According to the August 2002 Pre -CAP Monitoring Report prepared by Engineering
Tectonics, P.A. (ETPA), three 10,000 gallon gasoline underground storage tanks (USTs),
and one 8,000 gallon diesel UST were removed in November 1997. Upon the removal of the
USTs, soil contamination was detected and associated with the UST system. The exact
source of the release is unknown and can be one or a combination of the USTs, the piping,
and/or the dispensers. Carolina Oil Company was the owner and/or operator of the USTs.
The site was historically classified as an Intermediate Risk site by the North Carolina
Department of Environmental Quality (NCDEQ). Ongoing semi-annual monitoring and
reporting was being conducted by others during this time.
A Notice of Regulatory Requirements (NORR) dated May 3, 2012 indicated that the Pit Stop
BP site, of Intermediate Risk, was determined by the NCDEQ to be of sufficiently high
priority to allow funding by the State Trust Fund Program, Pursuant to the NORR and a
Notice of Violation (NOV) dated July 26, 2012, a Natural Attenuation Monitoring Report
(NAMR) was submitted by Shield Engineering, Inc. (Shield) to the NCDEQ on December
20, 2012. The December 2012 NAMR found that dissolved phase petroleum constituent
concentrations exceeded the NCDEQ Gross Contaminant Levels (GCLs) in monitoring well
MW-10B.
Additional soil sampling was performed in September 2013 in order to further delineate soil
contamination and was presented in a Comprehensive Site Assessment (CSA) Addendum. It
was noted that no soil contamination was found to be above the Residential Maximum Soil
Contaminant Concentration levels (MSCCs).
Based on groundwater results from the April 2014 sampling event, methyl tertiary butyl
ether (MTBE) and diisopropyl ether (IPE) were detected in water supply well WSW-1.
MTBE was detected at 29.9 micrograms per liter (ug/L) which was above the 15A NCAC 2L
Groundwater Standards (2L Standards) of 20 ug/L. Since MTBE was detected above the 2L
Standards and according to an NORR dated May 16, 2014, the Pit Stop BP site was
reclassified as High Risk. There are other petroleum fueling stations at this traffic
intersection so we are uncertain of the true source of the MTBE in WSW- 1. Since MTBE
has historically been detected above the 2L Standards and WSW-1 could not be sampled
during the July 2019 sampling event the Pit Stop BP site remains classified as High Risk,
according NORR dated September 24, 2019.
No Corrective Action Plan was ever conducted or implemented for this site. Semi-annual
Mobile Multi -Phase Extraction (MMPE) events along with routine sampling and reporting
are ongoing.
No non -LISTS are believed to have added to the site contamination.

Page 2
The site is located at 3690 Concord Parkway South in Concord, North Carolina (See Figures
l & 2). The property currently operates as a BP petroleum filling station and convenience
store. The surrounding properties are residential, commercial, or agricultural in use.
Groundeover at the site is comprised ofasphalt/concrete paved surfaces and landscaped areas
of grass. A one-story convenience store building along with a canopy is also located on the
site. Geology and hydrogeology information can be seen in Section 2.5
1.3 Existing Area Receptors:
Refer to the following figure for information and locations of property owners/occupants and
area receptors.
Refer to Table: Table I
Refer to Figures): Figure 3
Pursuant to NCDEQ requirements in 2012, a Site Reconnaissance and Receptor Survey
(receptor survey) was conducted by Shield by walking and/or driving publicly accessible
roads within a 1,500-foot radius of the site. During the survey, Shield personnel observed
supply wells and/or water meters from the streets and interviewed available occupants.
Figure 3 depicts the subject site and all properties within 1,500 feet of the site. Refer to
Table l for specific information. Locations of addresses are approximate, based on
perceived locations, using a topographic map, a tax map, and observations in the field,
There may be other supply wells or water teeters that were not readily visible at the time of
our survey,
Based on the 2012 receptor survey, seven water supply wells were observed within 1,500
feet of the source area. According to the property owner of WSW-1, located approximately
430 feet from the source area, the water supply well is used for irrigation and washing
vehicles and they are connected to municipal water for other water uses. The property owner
of WSW-2 approximately 530 feet from the source stated that they did not use the water
supply well. No one was home at WSW-3, WSW-4, and WSW-5 at the time of the supply
well survey. WSW-3 is approximately 740 feet from the site. WSW-4 is approximately 840
feet from the site. WSW-5 is approximately 940 feet from the site. The property owner at
WSW-6 located approximately 890 feet from the site stated that they did not use the well.
WSW-7 is approximately 1,290 feet from the site and is located on undeveloped land. Water
supply well survey letters were left at residences of WSW-4, WSW-5, and mailed to the
residences at WSW-3 and WSW-7. The survey letters from the residents of WSW-4 and
WSW-5 stated that they did not use the wells. The survey letter from the residents of WSW-
3 stated they use the well for washing vehicles. No information was returned by the
residents of WSW-7. All other parcels shown on Figure 3 are either connected to municipal
water or are undeveloped.

A receptor survey update was performed by Shield personnel on July 2, 2019 in order to
review the status ofknown receptors and present information on new receptors, if applicable.
Based on this receptor survey update, nine water supply wells were observed within 1,500
feet of the source area. No well was observed at 15 Pitts School Road NW. No well was
observed in the formerly shown location of WSW-2, however, a potential water supply well
was observed on this property. The WSW-2 property is currently vacant and the well is
approximately 270 feet from the source, A water supply well, WSW-8, is used for irrigation
and is located at 3200 Concord Parkway S. A water supply well, WSW-9, is used for
domestic purposes, such as drinking water, irrigation etc., is located at 172 Pitts School Road
SW. In addition, request for water supply well information surveys were sent to all known
properties were water supply wells have been observed. Only four surveys were returned at
the time of this report. The returned surveys are included in Appendix K.
There is an unnamed intermittent drainage feature approximately 50 feet west of the site that
ultimately flows into Rocky River and another unnamed intermittent drainage feature
approximately 900 feet west of the site that flows into Coddle Creek.
Because of the receptor information and previous groundwater contaminant level(s) being
detected in supply we]1 WSW -I, the site remains ranked by the NCDEQ as a "High Risk"
site according to NCDEQ NORR letter dated September 14, 2019. There are other
petroleum fueling stations at this traffic -intersection so we are uncertain of the true source of
the MTBE in WSW-1 .
e Proximity of Plume to Nearest Receptor(s):
There is an unnamed intermittent drainage feature approximately 50 feet west of the site that
ultimately flows into Rocky River.
The closest active water supply well (WSW-1) is located approximately 430 feet west
southwest from the source area of release. WSW-1 was used for washing cars; the residents
have municipal water for other water uses. Sometime after the .tune, 2018 sampling event, a
pipe in WSW-1 broke, the party(ies) who live at the property disconnected the electricity to
the well, and the well is not being used. This was confirmed in July, 20I9 by Shield's field
services manager. Previous interviews with the owner(s) of the well were not successful in
getting them to abandon their well and connect their car washing station to municipal water.
We previously advised the property owners of concern relative to drinking water from this
well, although the levels of MTBE and IPE are now below the 2L Standards. There are other
petroleum fueling stations at this traffic intersection so we have always been uncertain of the
true source of the MTBE and IPE in WSW-L

Corrective Action Plan activities have not been conducted at this site. Based on information
presented in the CSA Addendum, soil contamination in the form of benzene only was found
near one former sidewall ofthe large UST excavation above the Soil -to -Groundwater (STG)
MSCCs but not above the Residential MSCCs. No sail contamination was found near the
former diesel UST area above the STG or Residential MSCCS. All four samples collected
from around the smaller UST excavation area exceeded the STG MSCCs for gasoline related
constituents of concern (COCs) but none ofthese samples exceeded the Residential MSCCs.
MMPE events are currently being conducted semi-annually utilizing monitoring wells MW-
10B and MW-16 in July and January. MMPE events have been conducted in March 2014,
April 2015, January 2016, October 2016, .Tune 2017, November 2017, July 2018, and

The project site is located in the Charlotte Belt Litho -Tectonic Province of the Piedmont
Physiographic Province. The Piedmont Province is approximately 20,000 square miles located
in the State of North Carolina and lies between the Coastal Plain to the east and the Blue Ridge
Province to the west_ The topography is characterized as a plateau with ridges and valleys
formed as a result of stream erosion. Elevations within the Piedmont Province vary from
approximately 400 feet above sea level in the east to approximately 1,800 feet above sea level
near the foot of the Blue Ridge Province to the west. The soil overburden in the Piedmont
Plateau consists of predominately fine grained sediments transitioning into saprolites. The
residual saprolites are predominately underlain by northeast/southwest trending metamorphic
and igneous rocks.
Based on soil classifications (Unified Soil Classification system), the soil lithology at the site
generally consists of silty sands, sands, clays, sandy clays, clayey silts, and sandy silts.
According to the Geologic Map ofNorth Carolina (1985), the site soils should be underlain by
Gabbro of the Concord Plutonic Suite.
Hydrogeological investigations were; to be performed during the CSA by others. Shield does
not have information pertaining to the CSA. CSA addendum activities were performed by
Shield in September and October 2013, however, no bydrogeological investigation was
performed as a part of those activities.
2.7 Evaluation of Site Assessment Information
Groundwater— The following Groundwater Summary and referenced figures are based on the
December 12, 2019 routine sampling event:
* Dissolved phase petroleum constituent compounds were detected in concentrations
above the 2L Standards in monitoring wells MW-1 OB, MW-13, and MWA 6.
* The two largest contaminant plumes are benzene and MTBE.
■ The benzene plume greater than the 2L Standards is approximately 113 feet in length and
approximately 44 feet in width. The areal extent of the benzene plume is approximately
3,951 square feet.
■ The MTBE plume greater than the 2L Standards is approximately 43 feet in length and
30 feet in width. The areal extent of the MTBE plume is approximately 987 square feet.

MTBE was detected at a concentration of 1 micrograms per liter (ug11) in supply well
WSW-1 during the June 26, 2018 sampling event. There was no power to well during
the December 12, 2019 sampling event and the well was not sampled. There are other
petroleum fueling stations at this traffic intersection so we are uncertain of the true
source of the MTBE in WSW-1. Refer to the following Tables and Figures:
Refer to Tables: Tables 3 and 4
Refer to Figures: Figures 5 through 7
• Soil
• Based on information presented in the CSA Addendum dated December 3, 2013, soil
contamination in the form of benzene only was found near one former sidewall of the
large LIST excavation above the STG MSCCs but not above the Residential MSCCs. No
soil contamination was found near the former diesel UST area above the STG or
Residential MSCCS. All four samples collected from around the smaller UST
excavation area exceeded the STG MSCCs for gasoline related CRCs but none of these
samples exceeded the Residential MSCCs.
• Soil monitoring was not required by the NCDEQ during this reporting period. Historical
soil information has been provided in previous reports.

5.0 CONCLUSIONS AND RECOMMENDATIONS
5.1 Interpretations of Submitted Data:
Monitoring Report
January 31, 2020
Page 10
■ The site is a High Risk site because of supply well W SW- I being located within 500 feet
of the site. WSW-1 has also been historically impacted with MTBE. There are other
petroleum fiteling stations at this traffic intersection so we are uncertain of the true
source of the MTBE in WSW-1. Due to the no power at the well, WSW-1 was not
sampled during the December 2019 sampling event. The owner was not at home during
the routine sampling event.
• Dissolved phase petroleum constituent compounds were detected in concentrations
above 2L Standards in MW-10B, MW-13, and MW-16.
• The current contaminant mass, as calculated from the December 12, 2019 routine
sampling event and areal plume area (combination of benzene and MTBE plumes) is
approximately 1,783 grams and 3,951 square feet, respectively. This contaminant mass
is an decrease from the July 2019 sampling event which was approximately 3,368 rams.
• The concentration of benzene increased above the 2L Standard in MW-13 since the
previous routine sampling event.
• Diisopropyl ether (1PE) at the site has decreased below 2L Standards.
• Contaminant Mass has decreased from approximately 3,400 grams in July 2019 to
approximately 1,800 grams in December, 2019.
• Due to power at the well, WSW- i was not sampled during the July 2019 sampling event.
The owner was not at home during the routine sampling event.
5.2 Recommendations
• Shield recommends the continuance of semi-annuai sampling of the site monitoring
wells and water supply well WSW-1.
• Shield's project director discussed the site with the current NCDEQ incident manager on
November 6, 2019 as follow up to the NCDEQ NORR letter dated September 24, 2019.
It was determined that two more sampling rounds, after the July 2019 sampling event,
with similar sampling results to the July 2019 results were needed before the site could
be closed with a Notice of Residual Petroleum (NORP) deed restriction.
■ Based on the December 2019 sampling results, only one more round of sampling with
similar results should be required before the site can be closed with a Notice of Residual
Petroleum (NORP) deed restriction.
