2.0 EXECUTIVE SUMMARY
This Groundwater Monitoring Report (GW Report) summarizes petroleum hydrocarbon impacts in
groundwater from an apparent release of petroleum-related constituents in March 1989, identified
during a subsurface investigation (Incident Number 6760), and subsequently in April 2005, during
the removal of underground storage tanks (USTs) (Incident Number 36190), located at Exprezit
#503, 910 First Avenue SW, Hickory, Catawba County, North Carolina (Site). CES Group
Engineers, LLP (CES) has been authorized to perform groundwater monitoring activities by the
North Carolina Department of Environmental Quality (NCDEQ), represented by Scott Ryals, PE,
Environmental Engineer.
During this monitoring period, groundwater samples were collected from monitoring wells MW-3,
MW-5, MW-7, MW-10, MW-21, and MW-23 on August 2, 2023, and analyzed for petroleum
hydrocarbon constituents. Petroleum hydrocarbon constituents in groundwater were reported
ABOVE the 2L Standard from the following monitoring well:
MW-21: naphthalene (41.8 ug/l) and aliphatic C5-C8 (1,530 ug/l).
All other petroleum constituents in groundwater were reported BELOW 2L Standards from MW-3,
MW-5, MW-7, MW-10, MW-21, and MW-23.
Petroleum hydrocarbon constituents in groundwater were reported BELOW the Gross Contaminant
Level (GCL) Standard in MW-3, MW-5, MW-7, MW-10, MW-21, and MW-23.
Free product was not detected in any of the onsite groundwater monitoring wells.
According to information retrieved from the NCDEQ UST Incidents Map, the subject site was
previously assigned a Low-Risk classification by NCDEQ.
No water supply wells and/or other receptors were identified within 1,500-feet of the site during the
completion of a Receptor Survey in May, 2023.
This report provides data necessary to fulfill a GW Report, in accordance with 15A NCAC 2L.0100,
and is formatted in conformance with Appendix A of the Guidelines for Assessment and Corrective

4.0 SITE HISTORY AND CHARACTERIZATION
The subject site is located at 910 First Avenue SW, Hickory, North Carolina, at the intersection of
First Avenue SW and Ninth Street SW, and is currently unoccupied and vacant, and has been
further identified as Catawba County Parcel ID Number (PIN) 370205197350. Figures 1 and 2
depict a Site Location Map and Site Plan, respectively.
According to an online review of the NCDEQ UST Incidents Map and historical reports, apparent
releases of petroleum-related constituents were reported to NCDEQ on March 3, 1989, and April
13, 2005, and were subsequently assigned Incident Numbers 6760 and 36190, respectively, with
the site classified as Low-Risk for a regulated (R) and commercial (C) UST system. The site is
bordered to the north by an unoccupied and vacant building, on the east by Ninth Street SW with a
business (Buy It Right Auto Sales #1, Inc.) located across the roadway, to the south by First Avenue
SW with a business (Sheets Wrecker Service & Storage) located across the roadway, and on the
west by a single-family residence (mobile home). The subject site is situated in an area of
commercial, industrial, and residential land uses. Subject Property structures include a main
structure located on the north-central portion of the site, with a detached canopy immediately to the
south of the main structure, and with the former USTs located immediately to the northeast of the
main structure.
According to a review of historical reports prepared for TOC Retail, Inc (TOC Retail) by Edgerton
Environmental Services, Inc of Cary, North Carolina (Edgerton), previous investigations at the site
for Incident Number 6760 included the installation of soil borings and up to 20 groundwater
monitoring wells in the early 1990’s, with subsequent soil and groundwater sampling reporting
concentrations of petroleum-related constituents above applicable NCDEQ Standards, and the
operation and maintenance of a Vacuum Extraction System (VES) from March, 1992 to an
undetermined date, with known operation of the VES for at least 1.5-years based on reviewed
reports.
Additionally, according to a review of historical reports prepared for Exprezit ! Convenience Stores,
LLC (Exprezit !) by Advanced Environmental Technologies, LLC of Lakeland, Florida (Advanced),
previous investigations at the site for Incident Number 36190 included the installation of additional
soil borings and groundwater monitoring wells in 2005 and 2006, with subsequent soil and
groundwater sampling reporting concentrations of petroleum-related constituents remaining above
applicable NCDEQ Standards, and the excavation and removal of the UST system in February,
2005. During the removal of the UST system in February 2005, it was reported by Advanced that
contaminated soils were not excavated from the area of former USTs, dispenser islands or product
lines.
Historical reports for Incident Numbers 6760 and 36190 are included in Appendix A.
Since the completion of soil and groundwater sampling, conducted in October 2005 and September
2006, respectively, no further investigative measures are known to have occurred for Incident
Numbers 6760 and 36190. No further information regarding the site history and/or release
characterization been made available to CES, nor is believed to be readily available to review for
this site.

4.4 Release Description
Incident Number 6760
Facility ID Number: 00-0-0000029594
According to a review of a Comprehensive Site Assessment Addendum and Vacuum Extraction
System Operation Report, dated February, 1994, prepared for TOC Retail by Edgerton, Incident
Number 6760 was issued by NCDEQ to TOC Retail in May, 1989, after subsurface investigation
activities (i.e., the installation of soil borings and groundwater monitoring wells) reported that soil
and groundwater at the site had been impacted by petroleum-related constituents.
Incident Number 36190
Facility ID Number: 00-0-0000007549
According to a review of a Tank Closure Report, dated April 11, 2005, prepared for Exprezit ! by
Advanced, Incident Number 36190 was issued by NCDEQ to Exprezit in April 2005, after
contaminated soils were encountered during the excavation and removal of the UST system at the
site.
4.5 Site Characteristics
According to Catawba County GIS Maps, the subject property is zoned General Business (C-2),
with Catawba County Parcel Identification Number 370205197350, occupying an approximate area
of 0.52-acres. The subject site is situated at the intersection of First Avenue SW, a 2-lane, asphalt
surfaced, urban section roadway, and Ninth Street SW, a 2-lane, asphalt surfaced, urban section
roadway. The subject site contains one main structure located on the north-central portion of the
CES Project No. 8123.0323E
September 1, 2023
8
site, an approximate 1,612-square feet building that is currently unoccupied and vacant with a
detached canopy, which previously operated as a convenience store and gasoline service station,
and was reportedly constructed in the year 1961. The remainder of the subject site contains
asphalt-pavement and concrete entrance ways and parking areas, and landscaped areas.
Based on onsite observations and a review of historical documents, natural surface drainage at the
subject property generally flows in a westerly direction. While not always the case, groundwater
flow direction typically follows the direction of surface water flow, and is, therefore, anticipated to
flow westerly. The subject site is served by electrical and telecommunication utilities, as well as
public water distribution and sanitary sewer services provided by the City of Hickory. No water
supply wells or septic systems were observed onsite. The subject site is situated in an area of
commercial, industrial, and residential land use. A railroad right-of-way is located approximately
300-feet to the north of the site. The site location in relation to area land use is illustrated in
Figures 1 and 2.
4.6 Affected Property Owners and Occupants
The subject site where the contamination was initially discovered in March 1989 and April 2005,
with residual contamination remaining in-situ, as evident by groundwater analytical results reported
from MW-21 during the August 2, 2023, groundwater monitoring and sampling event, has been
found to be centrally located on the subject site and southwest of the former USTs. The 2L
groundwater contaminate plume is presumed to extend around groundwater monitoring well MW-
21, and based on the estimated extent of VOC concentrations from monitoring wells located on the
perimeter of the site, nearby property owners and occupants are not expected to be affected.
4.7 Receptor Information
.
A Receptor Survey was previously completed at the site in March and April, 2023, with the
information submitted to NCDEQ in a Receptor Survey Report, dated May 31, 2023, which is
summarized below:
Water Supply Wells:
A water supply well survey was conducted by completing the windshield and walking survey on
March 24, 2023, contacting the City of Hickory Public Utilities Department, and sending out Request
for Water Supply Well Information forms to property owners located within a 500-feet radius of the
subject property.
During the walking and windshield survey, no water supply wells were visually observed within 500-
feet of the site. According to information obtained from the subject property owner, nearby and
surrounding property owners, a review of NCDEQ SWAPInfo 2.0 and historical documents, no
water supply wells are known to exist within a 1,500-feet radius of the site.
On May 5, 2023, CES sent out Appendix A - Request for Water Supply Well Information forms to
the 30 properties within a 500-feet radius of the subject property. A total of five Water Supply Well
Information forms were returned to CES, or information was otherwise communicated to CES,
which did not report the presence of water supply wells within a 500-feet radius of the site. CES
reviewed applicable online sources for properties within 1,500-feet of the site, including the NC
SWAPInfo 2.0 Map and NC One Map - Public Water Supply Water Resources Map and Catawba
County’s GIS Real Estate System, which did not report the presence of water supply wells.
CES Project No. 8123.0323E
September 1, 2023

Public Water Supplies:
According to the NC One Map - Public Water Supply Water Resources Map, no public water supply
wells are known to exist within a 1,500-feet radius of the subject property.
Municipal water distribution systems provided by the City of Hickory are available to serve the
subject property and surrounding properties.
Surface Water:
The nearest surface water body to the site, Geitner Branch, a Class C surface water body according
to the NC One Map - Surface Water Classifications, is located approximately 1,350-feet to the
southwest of the site.
According to the NC One Map – Surface Water Intakes Map, no surface water intakes are located
within a 1,500-feet radius of the subject site.
Wellhead Protection Areas:
According to the NC SWAPInfo 2.0 Map and Database, no approved wellhead protection areas or
plans are located within a 1,500-feet radius of the subject site.
Deep Aquifers in the Coastal Plain Physiographic Region:
Not Applicable to the subject site as the site lies within the Piedmont Physiographic Region.
Subsurface Structures:
Underground utilities have been identified at and adjacent to the subject site, and the potential
exists for soil and groundwater contamination to be in contact with these underground utilities.
Groundwater has historically been measured at approximately 22 to 26-feet below ground surface
at the site. Because the underground utilities are expected to be at a shallower depth than 22 to
26-feet, the utility lines would not be considered receptors or conduits for ground water contaminant
migration. No subsurface structures have been identified at the site.
Table B-5 summarizes public and private water supply well and other receptor information.
4.8 Remedial Plan Implementation
To date, it is the understanding of CES that a remedial plan has not been submitted and/or
implemented for the subject site.
4.9 Remediation Progress
Not applicable.

5.0 CURRENT SITE ASSESSMENT INFORMATION
Prior to the commencement of the groundwater monitoring and sampling event, CES prepared and
reviewed a site-specific Job Hazards Analysis (JHA) and Emergency Management and Health &
Safety Plan (HASP) acknowledging that potential hazards exist onsite, which were properly
recognized and evaluated by onsite personnel. A copy of the site-specific JHA and HASP are
included in Appendix C.
5.1 Water Level and Free Product Thickness Measurements
During the groundwater monitoring and sampling event, depth to groundwater measurements were
collected from MW-3, MW-5, MW-7, MW-10, MW-21, and MW-23.
Depth to groundwater was measured and recorded utilizing a water level meter capable of detecting
light non-aqueous phase liquid (LNAPL or Free Product) to an accuracy of 0.01 feet.
Free product was not detected in any site related monitoring wells.
After measuring depth to groundwater at each monitoring well, the water level meter was
decontaminated by using a soapy water mixture (alconox and water).
Depth to groundwater ranged from 23.30-feet below top of casing (TOC) in MW-5 to 25.90-feet
below TOC in MW-23 on August 2, 2023. Based on visual observations and depth to groundwater
measurements collected on August 2, 2023, groundwater flow direction is anticipated to flow in a
westerly direction. A summary of depth to groundwater measurements are included in Table B-9
and in Appendix C, respectively.
5.2 Groundwater Monitoring and Sampling Event
After collecting depth to groundwater measurements, and after calculating the volume of water to be
removed from the above referenced monitoring wells, a dedicated 1.5-inch disposable bailer was
used to purge approximately three to five well volumes from each monitoring well. Groundwater
samples were then collected in laboratory provided glassware, placed on ice, and submitted under
chain of custody (COC) procedures to Waypoint Analytical (Waypoint), of Charlotte, NC on August
2, 2023, for analysis of 6200B, including MTBE and IPE/EDB, VPH, EPH, and Lead.
5.3 Surface Water Monitoring Event
Not applicable. No surface water monitoring events were conducted during this groundwater
monitoring and sampling event.
5.4 Soil Monitoring Events
Not applicable. No soil monitoring events were conducted during this groundwater monitoring and
sampling event.
5.5 Summary of Groundwater and Free Product Assessment Information
Petroleum hydrocarbon constituents in groundwater were reported ABOVE the 2L Standard from
the following monitoring wells:
CES Project No. 8123.0323E
September 1, 2023
11
MW-21: naphthalene (41.8 ug/l) and aliphatic C5-C8 (1,530 ug/l).
A groundwater elevation plan for the August 2, 2023, groundwater monitoring event is included as
Figure 3. A VOC isoconcentration plan for the August 2, 2023, groundwater monitoring and
sampling event is included as Figure 4. A summary of groundwater analytical results is included on
Table B-4. Copies of groundwater laboratory analytical reports are included as Appendix D.
5.6 Site Geology and Hydrogeology
According to the Geological Map of North Carolina (1985), the subject site is located within the
Piedmont Physiographic Province, is underlain by the metamorphic rocks of the Inner Piedmont,
Chauga Belt, Smith River Allochthon, and Sauratown Mountain Anticlinorium, and is within a mica
schist formation. A description of the underlying Rock Unit CZms is garnet, staurolite, kyanite or
sillimanite occurring locally; lenses and layers of quartz schist, micaceous quartzite, calc-silicate
rock, biotite gneiss, amphibolite and phyllite.
According to the US Department of Agriculture, Natural Resources Conservation Service, Web Soil
Survey, soils at the subject property consist of Clifford sandy loam (CfB), which generally have 2 to
6 percent slopes, and are classified as well drained sandy loam (0 to 10-inches), clay (10 to 47-
inches), clay loam (47 to 57-inches) and loam (57 to 80-inches). Parent materials were classified
as saprolite derived from granite and gneiss and/or schist.
According to a Limited Site Assessment Report, dated May 5, 2006, and prepared by Advanced
Environmental Technologies, LLC, apparent groundwater flow direction at the site is in a westerly
direction.
Based upon groundwater surface elevations, as measured from onsite monitoring wells on August
2, 2023, as summarized in Table B-9, and from onsite observations relative to the general gradient
at the site, apparent groundwater movement across the site is presumed to flow in a westerly
direction. A groundwater elevation plan for the August 2, 2023, groundwater monitoring event,
depicts groundwater elevations and apparent flow direction to the west, is presented as Figure 3.
5.7 Evaluation of Groundwater and Free Product Thickness Information
Based on VOC concentrations (naphthalene and aliphatic C5-C8) reported above the 2L Standard
from MW-21, located southwest of the former USTs, and with MW-3, MW-5, MW-7, MW-10, and
MW-23 reporting VOC concentrations below the 2L Standard, the extent of the contamination plume
is estimated to extend around groundwater monitoring well MW-21 for an unknown extent. The
estimated extent of the contaminant plume, as reported by VOC concentrations, is depicted on
Figure 4.
Free product was not detected in any of the onsite groundwater monitoring wells.
No soil or surface water monitoring events were conducted during this groundwater monitoring and
sampling event.
The data obtained and reported herein is representative of conditions only at the referenced
monitoring well locations, and is not necessarily indicative of conditions elsewhere on the subject
site.

9.0 CONCLUSIONS AND RECOMMENDATIONS
9.1 Conclusions
The findings of the August 2, 2023, groundwater monitoring and sampling event are as follows:
Six groundwater monitoring wells (MW-3, MW-5, MW-7, MW-10, MW-21, and MW-23) were
monitored and sampled for 6200B, including MTBE and IPE/EDB, VPH, EPH, and Lead.
LNAPL or Free Product was not detected in MW-3, MW-5, MW-7, MW-10, MW-21, and
MW-23,
Depth to groundwater measurement ranged from 23.30-feet below TOC in MW-5 to
25.90feet below TOC in MW-23,
Apparent groundwater flow direction is to the west,
Petroleum constituents (naphthalene and C5-C8 aliphatics) were reported ABOVE the 2L
Standard in MW-21, and
Petroleum constituents were reported BELOW the GCL Standard in all sampled wells, MW-
3, MW-5, MW-7, MW-10, MW-21, and MW-23.
9.2 Recommendations
Based upon groundwater concentration levels reported above the 2L Standard but below the GCL
Standard from MW-21, and the previously reported Low-Risk classification, without a foreseeable
risk of impacting nearby receptors due to the reported concentration levels of petroleum-related
constituents, and with the historical and future planned use of the subject site as a commercial
business, it is the opinion of CES that a Notice of Residual Petroleum (NRP) can be placed on the
property.
However, during any potential and/or future site redevelopment activities, property transactions,
and/or site improvements, it is the recommendation of CES that additional soil and groundwater
assessment, monitoring and/or remediation activities be conducted at the site, as the data obtained
and reported herein is representative of conditions only at the referenced monitoring well locations
(MW-3, MW-5, MW-7, MW-10, MW-21, and MW-23), and are not necessarily indicative of
conditions elsewhere on the subject site.

2.0 EXECUTIVE SUMMARY
This Receptor Survey Report was prepared to identify potential receptors located within a 1,500-
feet radius of the property located at 910 First Avenue, Southwest, Hickory, Catawba County, North
Carolina (the Site), which has been identified as Exprezit #503 within the Underground Storage
Tank (UST) section of the North Carolina Department of Environmental Quality (NCDEQ). CES
Group Engineers, LLP (CES) has been authorized to perform this receptor survey by the NCDEQ,
represented by Scott Ryals, PE, Environmental Engineer.
As part of this work scope, a water supply well survey was conducted by performing a windshield
and walking survey on March 24, 2023, contacting the City of Hickory Public Utilities Department,
and sending out Request for Water Supply Well Information forms to property owners located within
a 500-feet radius of the subject property. Additionally, available historical documents for Incident
Numbers 6760 and 36190 were reviewed for information relative to the apparent release condition,
and potential impacts to nearby water supply wells.
According to a review of available and selected historical documents, retrieved from NCDEQ’s
Division of Waste Management’s Document Management System (aka Laserfiche) for Incident
Numbers 6760 and 36190, subsurface impacts to soil and groundwater are known to exist at the
site, based on the last round of samples collected by other environmental consultants, which
reported petroleum-related constituents in soil (September, 2006) above applicable state standards
from the areas of the former USTs, product lines and dispensers, with concentrations of petroleum-
related constituents in groundwater reported above 2L Standards (October, 2005) from monitoring
wells located across the site.
No water supply wells and/or other receptors were identified within 1,500-feet of the site during the
Receptor Survey.
Based on the reported presence of petroleum-related constituents in soil and groundwater above
applicable standards from the last round of sampling conducted at the site in September, 2006 and
October, 2005, respectively, it is recommended that up to four soil borings be installed in the areas
of previous soil exceedances, ie the area of the former USTs, dispenser islands and product lines,
and up to six existing groundwater monitoring wells be sampled from wells previously reporting 2L
exceedances and/or located along the property boundaries, as depicted on Figure 2, in order to
evaluate current subsurface soil and groundwater conditions in comparison to updated state
standards, and to determine if regulatory closure can be achieved through a Notice of Residual
Petroleum (NRP) or No Further Action (NFA).

4.0 SITE HISTORY AND CHARACTERIZATION
The subject site is located at 910 First Avenue, Southwest, at the intersection of First Avenue,
Southwest and Ninth Street, Southwest, is currently unoccupied and vacant, with one main
structure located on the north-central portion of the site, with a detached canopy immediately to the
south of the main structure, and has been further identified as Catawba County Parcel ID Number
(PIN) 370205197350. The former USTs were reportedly located to the east of the main structure ,
on the northeastern portion of the site. Figures 1 and 2 depict a Site Location Map and Site Plan,
respectively.
According to Catawba County GIS Maps, the subject property is zoned General Business (C-2),
with Catawba County Parcel Identification Number 370205197350, occupying an approximate area
of 0.52-acres. The subject site is situated at the intersection of First Avenue, Southwest, a 2-lane,
asphalt surfaced, urban section roadway, and Ninth Street, Southwest, a 2-lane, asphalt surfaced,
urban section roadway. The subject site contains one main structure located on the north-central
portion of the site, an approximate 1,612-square feet building that is currently unoccupied and
vacant, which previously operated as a convenience store and gasoline service station, and was
reportedly constructed in the year 1961. The remainder of the subject site contains asphalt-paved
and concrete entrance ways and parking areas, and landscaped areas. Based on onsite
observations and a review of historical documents, natural surface drainage at the subject property
generally flows in a westerly direction. While not always the case, groundwater flow direction
typically follows the direction of surface water flow, and is, therefore, anticipated to flow westerly.
The subject site is served by electrical and telecommunication utilities, as well as public water
distribution and sanitary sewer services provided by the City of Hickory. No water supply wells or
septic systems were observed onsite. The subject site is situated in an area of commercial,
industrial and residential land use. A railroad right-of-way is located approximately 300-feet to the
north of the site. The site location in relation to area land use is illustrated in Figures 1 and 2.

4.5 Receptor Information
Windshield and Walking Survey:
On March 24, 2023, a representative of CES conducted a windshield and walking survey of the
subject property, and accessible properties withing a 500-feet radius of the site. Visual information
obtained from the windshield and walking survey has been summarized as follows:
Water supply well(s) were not visually identified on the site, nor on properties located along
First Avenue, Southwest; Ninth Street, Southwest; Tenth Street, Southwest and Main Street,
Southwest; and
Municipal water lines, meters and fire hydrants were observed along First Avenue,
Southwest; Ninth Street, Southwest; Tenth Street, Southwest and Main Street, Southwest.
Water Supply Wells:
As part of this work scope, a water supply well survey was conducted by completing the windshield
and walking survey on March 24, 2023, contacting the City of Hickory Public Utilities Department
and sending out Request for Water Supply Well Information forms to property owners located within
a 500-feet radius of the subject property.
During the walking and windshield survey, no water supply wells were visually observed within 500-
feet of the site. According to information obtained from the subject property owner, nearby and
surrounding property owners, a review of NCDEQ SWAPInfo 2.0 and historical documents, no
water supply wells are known to exist within a 1,500-feet radius of the site.
On May 5, 2023, CES sent out Request for Water Supply Well Information forms to the thirty
properties within a 500-feet radius of the subject property. A total of five Water Supply Well
Information forms were returned to CES, or information was otherwise communicated to CES,
which did not report the presence of water supply wells within a 500-feet radius of the site. CES
reviewed applicable online sources for properties within 1,500-feet of the site, including the NC
SWAPInfo 2.0 Map and NC One Map - Public Water Supply Water Resources Map and Catawba
County’s GIS Real Estate System, which did not report the presence of water supply wells.
Public Water Supplies:
According to the NC SWAPInfo 2.0 Map and NC One Map - Public Water Supply Water Resources
Map, no public water supply wells are known to exist within a 1,500-feet radius of the subject
property.
Municipal water distribution systems provided by the City of Hickory are available to serve the
subject property and surrounding properties.
Surface Water:
The nearest surface water body to the site, Geitner Branch, a Class C surface water body according
to the NC One Map - Surface Water Classifications, is located approximately 1,350-feet to the
southwest of the site.
According to the NC One Map – Surface Water Intakes Map, no surface water intakes are located
CES Project No. 8123.0323E Page 9
May 31, 2023
within a 1,500-feet radius of the subject site.
Wellhead Protection Areas:
According to the NC SWAPInfo 2.0 Map and Database, no approved wellhead protection areas or
plans are located within a 1,500-feet radius of the subject site.
Deep Aquifers in the Coastal Plain Physiographic Region:
Not Applicable to the subject site as the site lies within the Piedmont Physiographic Region.
Subsurface Structures:
Underground utilities have been identified at and adjacent to the subject site, and the potential
exists for soil and groundwater contamination to be in contact with these underground utilities.
Groundwater has historically been measured at approximately 22 to 26-feet below ground surface
at the site. Because the underground utilities are expected to be at a shallower depth than 22 to
26-feet, the utility lines would not be considered receptors or conduits for ground water contaminant
migration. No subsurface structures have been identified at the site.
Figure 3 depicts a 1,500-feet Potential Receptor and Land Use Map.
Table B-5 summarizes public and private water supply well and other receptor information.
4.6 Land Use
Land use in the vicinity of the subject property can be characterized as commercial, industrial and
residential uses.
Table B-6 summarizes contiguous property owners and occupants.
No sensitive land use features, such as schools, daycare centers, nursing homes, hospitals,
playgrounds, churches, camps, or other places of assembly, have been identified within 1,500-feet
of the source of the release, with the exception of Hickory Optimist Park located approximately 900-
feet to the southeast and Vintage City Church located approximately 1,500-feet to the northeast of

6.0 ASSESSMENT INFORMATION
6.1 Site Geology and Hydrogeology
According to the Geological Map of North Carolina (1985), the subject site is located within the
Piedmont Physiographic Province, is underlain by the metamorphic rocks of the Inner Piedmont,
Chauga, Smith River Allochthon and Sauratown Mountain Belt, and is within a mica schist
formation. A description of the underlying Rock Unit CZms is garnet. Staurolite, kyanite or
sillimanite occurring locally; lenses and layers of quartz schist, micaceous quartzite, calc-silicate
rock, biotite gneiss, amphibolite and phyllite.
According to the US Department of Agriculture, Natural Resources Conservation Service, Web Soil
Survey, soils at the subject property consist of Clifford sandy loam (CfB), which generally have 2 to
6 percent slopes, and are classified as well drained sandy loam (0 to 10-inches), clay (10 to 47-
inches), clay loam (47 to 57-inches) and loam (57 to 80-inches). Parent materials were classified
as saprolite derived from granite and gneiss and/or schist.
According to a Limited Site Assessment Report, dated May 5, 2006, and prepared by Advanced
Environmental Technologies, LLC, apparent groundwater flow direction at the site is in a westerly
direction.
6.2 Sampling Activities
No soil, groundwater, surface water or water supply well samples were collected as part of the
receptor survey. However, based on a review of historical soil and groundwater laboratory results
from samples last collected in September, 2006 and October, 2005, respectively, petroleum-related
constituents in soil and groundwater were reported above their respective standards.
CES Project No. 8123.0323E Page 15
May 31, 2023
7.0 CONCLUSIONS AND RECOMMENDATIONS
Based on the reported presence of petroleum-related constituents in soil and groundwater above
applicable standards from the last round of sampling conducted at the site in September, 2006 and
October, 2005, respectively, it is recommended that up to four soil borings be installed in the areas
of previous soil exceedances, ie the area of the former USTs, dispenser islands and product lines,
and up to six existing groundwater monitoring wells be sampled from wells previously reporting 2L
exceedances and/or located along the property boundaries, as depicted on Figure 2, in order to
evaluate current subsurface soil and groundwater conditions in comparison to updated state
standards, and to determine if regulatory closure can be achieved through a NRP or NFA.
