2.0 EXECUTIVE SUMMARY

This Groundwater Monitoring Report (GW Report) summarizes petroleum hydrocarbon impacts in
groundwater since the submission of the last GW Report, dated April 22, 2022, for the suspected
release of gasoline from two (2) adjacent underground storage tank (UST) systems at the Former
East Lincoln Fire Station, located at 7654 NC Highway 73 in Stanley, North Carolina (hereafter
identified as the site, subject site, subject property, or property). CES has been authorized to
perform groundwater monitoring and sampling activities by the East Lincoln Fire Department
(ELFD), represented by Timothy Tench, Fire Chief.

During this monitoring period, groundwater samples were collected from monitoring wells (MW)
MW-101, MW-103, MW-104, MW-201, MW-202, MW-203, MW-301, MW-303, MW-401, MW-402,
and MW-501 and analyzed for petroleum hydrocarbon constituents on September 26, 2023.
Petroleum hydrocarbon constituents were reported above the 2L Standards in monitoring wells
MW-101, MW-103, MW-104, MW-301, MW-401, and MW-501. Petroleum hydrocarbon constituents
were reported above the Gross Contamination Level (GCL) from the following monitoring wells
during this monitoring and sampling period:

 MW-101: benzene (24,000 ug/l), 1,2-dibromoethane (818 ug/l) and 1,2-dichloroethane
(1,690 ug/l).

 MW-104: benzene (24,100 ug/l) and 1,2-dibromoethane (445 ug/l).

 MW-301: benzene (6,820 ug/l).

 MW-401: benzene (8,510 ug/l) and 1,2-dibromoethane (93.1 ug/l).

A summary of groundwater analytical results for this September 26, 2023, groundwater monitoring
and sampling event are included in Table B-4A. A summary of historical groundwater analytical
results dating back to June 2014 are included in Table B-4B. A summary of historical water supply
well analytical results dating back to July 2014 are included in Table B-4C.

Light non-aqueous phase liquid (LNAPL) or free product was not detected in any of the onsite
groundwater monitoring wells. Because active water supply wells were identified within 1,000-feet of
the site, and groundwater contamination was reported above the GCLs, the site was previously
assigned a High-Risk classification by North Carolina Department of Environmental Quality
(NCDEQ). However, based on a defined linear contaminant plume, historical groundwater flow
direction to the southeast, the previous abandonment of water supply well (SW-5) located on the
adjacent property to the south-southwest, and during recent conversations with NCDEQ
representatives, reclassification of the site will be evaluated during the implementation of the
Corrective Action Plan (CAP). A CAP – Record of Decision (ROD), summarizing the objectives,
schedules, and milestones to track cleanup progress for the air sparge (AS) and soil vapor
extraction (SVE) system that was approved in the previously submitted CAP – Corrective Action
Design (CA Design) has been approved, and CES is currently working with remedial subcontractors
and vendors to revise costs, schedules, and timelines after noted delays in the approval process.

To date, no receptors have been reported to have been impacted by the reported petroleum
release, nor are said receptors at imminent risk of being impacted based on a review of historical
and current groundwater and water supply well data. Figure 1 depicts the 1,500-feet radius and
potential receptor map.

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
Action for UST Releases, effective June 21, 2023.

3.0 SITE HISTORY AND CHARACTERIZATION

The subject site consists of two (2) parcels, identified as east and west, respectively, situated along
the south line of NC Highway 73, with the west parcel being adjacent to the east line of South Pilot
Knob Road, as shown on Figure 2. A general merchandise retail store that also sold gasoline was
located on the west parcel, from the 1930s until approximately 1969. A wrecker service, owned and
operated by Shelton Duckworth, occupied the referenced retail store building from 1969 until 2004.
The retail sale of gasoline was reportedly conducted in association with both the general
merchandise store and the wrecker service until 1984. The gasoline UST systems, consisting of two
(2) adjacent 500-gallon tanks and a dispenser pump directly above each tank, were reportedly
removed from the site in early 1985, prior to tank registration mandates by the State of North
Carolina.

A building housing the newly formed ELFD was constructed on the site’s east parcel in 1956.
Following demolition of the first ELFD building in February 1990, the currently existing onsite
building was constructed and first occupied by the ELFD in October 1990. In 2002, ELFD acquired
the subject property from Shelton Duckworth, including both the east and west parcels. Duckworth
Wrecker Service moved to an offsite location in 2004, and the building on the site’s west parcel was
demolished to provide space for the currently existing parking lot, where the former tank basin is
located. ELFD occupied the existing onsite building from 1990 until 2008, when ELFD moved to its
current location at 406 South Pilot Knob Road. The existing onsite building was leased and
occupied by Tim Norman, Norman Tire and Auto from 2011 until January 2017. At that time, Mr.
Norman purchased the property from the ELFD and continues to operate an automobile tire and
repair facility. It is understood that Mr. Norman did not assume the environmental liability for
NCDEQ Incident 40323 from the ELFD during this property transaction.

An onsite water supply well reportedly served both the retail store/wrecker service building and the
initial ELFD building. The currently existing building, first occupied by ELFD in October 1990, has
reportedly been served by the Lincoln County public water distribution system since 1991. The
onsite well was reportedly abandoned in conjunction with the demolition of the former retail
store/wrecker service building in 2004.

3.2 UST Information
The retail sale of gasoline at the site was reportedly terminated in 1984, and the subject tanks were
reportedly removed in early 1985, prior to tank registration mandates by the State of North Carolina.
The gasoline UST systems reportedly consisted of two (2) adjacent 500-gallon tanks and a
dispenser pump directly above each tank. Procedural details of the 1985 closure and removal of the
two (2) gasoline UST systems are reportedly undocumented and unknown. Disposal details
concerning the UST systems, tank contents, soils, and/or other residual materials are reportedly
undocumented and unknown. The estimated location of the former adjacent UST systems was
determined in consultation with the tank owner/operator, Shelton Duckworth, and the current site
representative, Timothy Tench. Orientation of the adjacent tanks could not be recalled by the
owner/operator.

Currently available information concerning the two (2) subject USTs is summarized in Tables B-1
and B-2.
3.3 Non-UST Information
Not applicable. No aboveground storage tanks (AST) or other above ground vessels or substantial
petroleum storage containers are known to exist at the site.
3.4 Release Description
Soil contamination indicative of a petroleum product release near the reported location of two (2)
500-gallon gasoline USTs that were removed in 1985 was discovered during a Limited Phase II
Environmental Site Assessment in March 2014. Following receipt of laboratory data for collected
soil samples on March 5, 2014, indicating total petroleum hydrocarbon (TPH) levels equal to or
greater than the action level of 10-parts per million (ppm), a release was reported to NCDEQ on
March 6, 2014, and NCDEQ Incident 40323 was subsequently issued for the release condition.
Procedural details of the 1985 closure and removal of the two (2) 500-gallon gasoline UST systems
are reportedly undocumented and unknown. Disposal details concerning the UST systems, tank
contents, soils, and/or other residual materials are reportedly undocumented and unknown. The
release is believed to have occurred over an extended period, prior to 1985.
3.5 Site Characteristics
The subject commercial property, zoned for Neighborhood Business (B-N) use, includes two (2)
parcels, with Lincoln County Parcel Identification Number (PIN) 53015 and 30063, occupying a total
area of approximately 0.95-acre. Site improvements include an approximately 6,000-square feet,
single story, slab-on-grade building, with limited concrete paving along the building’s front face,
additional gravel-surfaced drives and parking areas, limited asphalt paving, and appurtenances.
The onsite building is situated on the eastern parcel, while the western parcel, where the subject
former tank basin is located, is occupied by a gravel-surfaced parking lot. The onsite building was
formerly a fire station utilized by the previous property owner, East Lincoln Fire Department, and the
entire site is currently occupied by Norman Tire & Auto, a retail and service business. The site is
situated in an unincorporated area of Lincoln County, in the southeastern quadrant of the
intersection of NC Highway 73 and South Pilot Knob Road, both of which are two (2)-lane, asphalt
surfaced, rural section roadways, with additional turn lanes at the referenced intersection. The
subject site is served by electrical and natural gas public utilities, as well as water distribution
service provided by Lincoln County. The site is currently served by an onsite septic system, with no
county sewer system service.

CES Project No. 7604.0321ED
November 30, 2023

The subject site is situated in an area of mixed commercial, agricultural, and low-density single-
family residential land use. Adjacent down-gradient land to the south and east of the site is an
approximately 45-acre tract that is undeveloped, except for a single-family residence that is
currently unoccupied. The site location in relation to area land use is illustrated in Figures 1 and 2.
3.6 Affected Property Owners and Occupants
The subject property (i.e., Lincoln County PIN 53015 and 30063) where the contamination was
discovered, and where the reported source area of the contaminated plume has come to be located
is currently owned by Tim Norman, who owns and operates Norman Tire & Auto on these two (2)
adjoining parcels.

An adjoining, and downgradient property (i.e., Lincoln County PIN 32896) to the south of the subject
property, where the contaminant plume has been documented to have migrated, is currently owned
by Chastain Terry Napier (Nixon Family).

Currently available information concerning Affected Property Owners and Occupants and Land Use
are summarized in Tables B-6 and B-10, respectively.
3.7 Receptor Information
Water Supply Wells:
Three (3) confirmed active drinking water supply wells, including two (2) inactive wells, were
identified within 1,000-feet of the subject site during initial site assessment activities. In July 2014,
samples were collected from the three (3) active drinking water supply wells, identified as SW-1,
SW-2, and SW-3, with historical analytical results presented in Table B-4C. A review of the
analytical results for these active water supply wells by an NCDEQ Environmental Toxicologist in
July 2014 resulted in a finding that no detected contaminants exceed applicable water standards,
and no use restrictions were recommended. The two (2) inactive water supply wells have reportedly
not been in use for more than 20 years and could not be sampled by conventional procedures in
July 2014. One (1) additional active drinking water supply well was identified within 1,500-feet from
the site and was not sampled in July 2014. On May 26, 2016, one (1) of the inactive private wells,
located approximately 270-feet downgradient of the site at 133 S. Pilot Knob Road (identified as
Well #5, PIN 32896, Owner: Bernice Nixon on Figure 3 and Table B-5), was abandoned by
Carolina Soil Investigations, Inc.

In June 2017, samples were collected from four (4) active drinking water supply wells, identified as
SW-1, SW-2, SW-3, and SW-4, and reported concentrations relatively consistent with the results
from the July 2014 event. Additionally, in March 2018, a sample collected from a newly installed
drinking water supply well, identified as SW-7 and located approximately 1,220-feet downgradient of
the contaminant plume, reported concentrations of chloroform (1.0 ug/l) and tetrachloroethylene
(1.6 ug/l) above laboratory method detection limits. A review of historical water supply well results
indicate that the concentrations reported from water supply well SW-7 in March 2018 are relatively
consistent with concentrations reported from water supply wells SW-1, SW-3, and/or SW-4.

Active drinking water supply wells (WSW-1, WSW-3, WSW-4, WSW-7) are scheduled to be
sampled in late November 2023, with the results being provided to Mr. Chris Clark of the Inactive
Hazardous Waste Section of NCDEQ, with a copy of the results to be provided to the UST Section
of NCDEQ.

CES Project No. 7604.0321ED
November 30, 2023
A summary of historical water supply well analytical results dating back to June 2014 are included in
Tables B-4B. Specific information concerning each of the water supply wells within 1,500-feet from
the site is presented in Table B-5. Corresponding supply well locations are depicted on Figure 1.

Public Water Supplies:
No public water supplies were identified within 1,500-feet of the subject site. The Lincoln County
public water distribution system is available at the site.

Surface Water:
No surface water bodies were identified within 500-feet of the site.

Wellhead Protection Areas:
Per the NCDEQ website, no wellhead protection areas are in Lincoln County.

Deep Aquifers in the Coastal Plain Physiographic Region:
Not applicable to the subject site.

Subsurface Structures:
Underground utilities have been identified at and adjacent to the subject site, and soil contamination
may be in contact with these underground utilities. Groundwater has historically been measured at
approximately 10 to 25-feet below ground surface (bgs) at the site. Because the underground
utilities are expected to be at a substantially shallower depth than 10-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.
3.8 Remedial Plan Implementation
A CAP – ROD, summarizing the objectives, schedules, and milestones to track cleanup progress
for the AS/SVE system proposed in the CAP – CA Design has been approved, and CES is currently
working with remedial subcontractors and vendors to revise costs, schedules, and timelines after
noted delays in the approval process.
3.9 Remediation Progress
Upon planned implementation of the proposed AS/SVE remedial system, progress of remediation
will be reported in future monitoring reports.

November 30, 2023
4.0 CURRENT SITE ASSESSMENT INFORMATION
4.1 Water Level and Free Product Thickness Measurements
During this groundwater monitoring and sampling period, depth to groundwater (DTW)
measurements were collected from monitoring wells MW-101, MW-103, MW-104, MW-201, MW-
202, MW-203, MW-301, MW-303, MW-401, MW-402, and MW-501 on September 26, 2023.

Depth to groundwater was measured and recorded utilizing a water level meter capable of detecting
LNAPL or free product to an accuracy of 0.01-feet.

Free product was not detected in any site related monitoring wells.

After measuring DTW at each monitoring well, the water level meters were decontaminated by
using a soapy water mixture (alconox and water).

Depth to groundwater September 26, 2023, ranged from 19.29-feet below top of casing (TOC) in
monitoring well MW-203 to 22.03-feet below TOC in monitoring well MW-501. A summary of
historical DTW measurements is included on Table B-9.
4.2 Groundwater Monitoring Event
After calculating the volume of water to be removed from the above referenced monitoring wells,
dedicated 1.5-inch disposable bailers were used to purge approximately three to five well volumes
from each monitoring well. Groundwater samples were then collected, placed on ice, and hand
delivered under chain of custody (COC) procedures to Waypoint Analytical (Waypoint), of Charlotte,
North Carolina, for analysis of volatile organic compounds (VOCs) by the U.S. Environmental
Protection Agency (EPA) Method 6200B and volatile petroleum hydrocarbons (VPH) by
Massachusetts Department of Environmental Protection (MADEP) methodologies.
4.3 Surface Water Monitoring Event
Not applicable. No surface water monitoring events were conducted during this groundwater
monitoring and sampling period.
4.4 Soil Monitoring Events
Not applicable. No soil monitoring events were conducted during this groundwater monitoring and
sampling period.
4.5 Summary of Soil, Groundwater, Surface Water and Free Product Assessment
Information
Petroleum hydrocarbon constituents were reported above the 2L Standards in monitoring wells
MW-101, MW-103, MW-104, MW-301, MW-401, and MW-501. Petroleum hydrocarbon
constituents, including site concentration levels, were reported above the GCL from the following
monitoring wells during this monitoring and sampling period:

 MW-101: benzene (24,000 ug/l), 1,2-dibromoethane (818 ug/l) and 1,2-dichloroethane
(1,690 ug/l).

10
CES Project No. 7604.0321ED
November 30, 2023
 MW-104: benzene (24,100 ug/l) and 1,2-dibromoethane (445 ug/l).

 MW-301: benzene (6,820 ug/l).

 MW-401: benzene (8,510 ug/l) and 1,2-dibromoethane (93.1 ug/l).

A groundwater elevation plan for the September 26, 2023, groundwater monitoring and sampling
event is included as Figure 3. A benzene isoconcentration plan for the September 26, 2023,
groundwater monitoring and sampling event is included as Figure 4. A summary of historical
groundwater analytical results dating back to June 2014 are included in Table B-4B. Copies of
groundwater laboratory analytical reports are included as Appendix A.
4.6 Site Geology and Hydrogeology
Underlying rock stratigraphy near the subject site is of the Paleozoic era, the Ordovian system, and
the Lower Paleozoic granitic rocks series. The area's predominant surficial soil component is
identified as Gaston, having the texture of a sandy clay loam. Gaston soils reportedly have
moderately fine or fine textures and slow infiltration rates. While the corrosion potential of site soils
is reported to be high, Gaston soils do not meet the requirements for classification as a hydric soil.
Other surficial and deeper soil types that may be expected to be found near the subject site are
generally classified as sandy loam, clay, loam, gravelly sandy loam, and fine sandy loam.

Site specific soils noted during the monitoring well installations at the site have consisted of mostly
Silt and Silty Clays from grade to approximately 30-feet bgs. Deeper soils observed during the
installation of two (2) Type III monitoring wells in the immediate vicinity of the source area were
comprised of Silt and Silty Clays to approximately 45-feet bgs, with Partially Weathered Rock
around 60-feet bgs and bedrock being encountered at 95-feet bgs.

Based upon top of casing and groundwater surface elevations, as measured in onsite and offsite
monitoring wells, and summarized in Table B-9, apparent groundwater movement across the site
during this groundwater monitoring and sampling period is in a southeasterly direction, which is
consistent with historical groundwater flow directions. A groundwater elevation plan for the
September 26, 2023, groundwater monitoring and sampling event, depicting the groundwater
elevations and flow direction, is presented as Figure 3.
4.7 Evaluation of Soil, Groundwater, Surface Water and Free Product Thickness
Information
The extent of the petroleum hydrocarbon plume appears to be defined in the northern, eastern,
western, and vertical directions. Concentrations of the contaminants of concern appear to be
generally reducing in the southern direction, yet petroleum hydrocarbon detections beyond the
natural gas pipeline easement, in MW-501 (previously above GCLs and currently above 2L
Standards), indicate that the southern extent of the plume has not been reached. Further soil
sampling and laboratory analysis would be necessary to evaluate the extent of petroleum
hydrocarbons in soil. In accordance with recent NCDEQ correspondences, upon completion and
implementation of the CAP, additional downgradient monitoring wells, located beyond the natural
gas pipeline and monitoring well MW-501, may be installed to evaluate the southern extent of the
contaminant plume.

Free product was not detected in any of the onsite groundwater monitoring wells.

The data obtained and reported herein is representative of conditions only at the referenced boring
and monitoring well locations and is not necessarily indicative of conditions elsewhere on the
subject or adjacent properties. During the groundwater monitoring and sampling of all offsite
monitoring wells, access agreements previously executed with the adjacent property owners were
utilized.
4.8 Soil and Groundwater Remediation
No soil and/or groundwater remediation activities were conducted during this groundwater
monitoring and sampling event.

5.0 CONCLUSIONS AND RECOMMENDATIONS
5.1 Conclusions
Since the submission of the GW Report, dated April 22, 2022, one groundwater monitoring and
sampling event has been conducted at the site to monitor groundwater concentrations and trends.
Active drinking water supply wells (WSW-1, WSW-3, WSW-4, WSW-7) are scheduled to be
sampled in late November 2023, with the results being provided to Mr. Chris Clark of the Inactive
Hazardous Waste Section of NCDEQ, with a copy of the results to be provided to the UST Section
of NCDEQ.

During this September 26, 2023, groundwater monitoring and sampling event, petroleum
hydrocarbon constituents were reported above the 2L Standards in monitoring wells MW-101, MW-
103, MW-104, MW-301, MW-401, and MW-501. Petroleum hydrocarbon constituents were reported
above GCL in monitoring wells MW-101, MW-104, MW-301 and MW-401, with maximum site
concentration levels of 24,100 ug/l (benzene in MW-104), 818 ug/l (1,2-dibromoethane in MW-101),
and 1,690 ug/l (1,2-dichloroethane in MW-101).

Free product was not detected in any of the onsite groundwater monitoring wells.

Groundwater laboratory results from this September 26, 2023, groundwater monitoring and
sampling event are relatively consistent with historical results, and indicate that the contaminant
plume is stable, not expanding, but exhibiting continued migration along the calculated groundwater
flow direction to the south (MW-501).

A review of groundwater analytical results from monitoring well MW-501 indicates that the southern
extent of the contaminant plume has not been reached, based on petroleum hydrocarbon
constituents remaining above 2L Standards and previously above GCLs.
5.2 Recommendations
Based upon groundwater concentration levels reported above GCLs, and the High-Risk
classification, it is recommended that groundwater and drinking water supply well monitoring
activities continue on a semi-annual to annual basis, until the remedial strategy under the recently
approved CAP is implemented. In accordance with recent NCDEQ correspondences, upon
completion and implementation of the CAP, additional downgradient monitoring wells, located
beyond the natural gas pipeline easement and monitoring well MW-501, may be installed to
evaluate the southern extent of the contaminant plume. Additionally, based on a defined linear
contaminant plume, historical groundwater flow direction to the southeast, the previous
abandonment of water supply well (WSW-5) located on the adjacent property to the south-
southwest, and during recent conversations with NCDEQ representatives, reclassification of the
Site from High-Risk to Low-Risk will be evaluated upon implementation and operation of the
AS/SVE remedial system.

During the proposed semi-annual to annual groundwater sampling events, monitoring wells located
within the GCL plume, and immediately up gradient (i.e., monitoring wells MW-103 and/or MW-303),
cross gradient (i.e., monitoring wells MW-201, MW-203 through MW-206, MW-302 and/or MW-305)
and down gradient (i.e., monitoring well MW-501) should be analyzed for petroleum hydrocarbon
constituents.

CES Project No. 7604.0321ED
November 30, 2023
As previously reported in Groundwater Monitoring Reports and the CA Design, if modifications to
the AS/SVE remedial system are required based on final NCDOT design and/or construction plans
associated with NC Highway 73 Project (STIP: R-5721/U-5765), which currently includes the
preliminary design of a turn-lane over a portion of the source area, NCDEQ representatives will be
contacted to discuss the proposed changes and potential impacts to the operation of the remedial
system.
