B. EXECUTIVE SUMMARY
The purpose of this report is to evaluate the current status of groundwater quality at the Rainbow
Pantry #5 site (Incident No. 3856) located at 1833 Elk Park Highway in Newland, Avery County, North
Carolina. Terracon completed this report to summarize the findings of assessment activities
performed on January 22, 2020. The site, located in a rural residential area, is currently unoccupied
and formerly operated as a convenience store with fueling services that appeared to be closed
during our site visit.
Based on limited regulatory file review information, an apparent release was reported on December
5, 1988 by the property owner when gasoline was discovered in an on-site vapor monitoring well
(leak detection monitoring) and evidence of gasoline was observed seeping into White Oak Creek
which is located approximately 80 feet west of the tank basin. A UST closure report was submitted to
the NCDEQ – Asheville Regional Office on February 27, 1999 by Tank Removal Service, Inc. The
report indicates an on-site 1,000-gallon kerosene tank was removed on January 29, 1999; however,
due to reporting inconsistencies, the closure report was deemed unsatisfactory by the NCDEQ. No
additional information was provided regarding the status of closure for the kerosene UST. A second
on-site UST (7,500-gallon gasoline tank) was reportedly removed from the site in May 2010 by
Southeastern Geological. The former location of the 7,500-gallon UST is apparently occupied by a
new underground tank. Reportedly, potable water is provided to the site from a water supply well
located on the adjacent property to the south. Based on our observations and historical information,
two gasoline USTs, a 4,000-gallon diesel UST and a heating oil UST (unknown capacity) are
apparently maintained on the property at the present time.
The release at the site was controlled initially by a pump and treat system installed by Delta
Environmental Consultants, Inc. (Delta). The remediation system suffered from multiple
operations/maintenance issues to the extent that Delta replaced the pump and treat system with an
air sparge system that was activated on October 29, 1997. Reportedly, the air sparge system
continued sporadic operations until approximately 2016 when Gipe & Associates (Gipe) transitioned
remedial activities to natural attenuation monitoring.

Terracon mobilized to the site on January 22, 2020 to conduct groundwater sampling activities at
monitoring wells MW-4/RW-4, MW-5/RW-5, an unidentified well located at the southeastern corner
of the store building, the water supply well located at the Pritchard residence, and a surface water
sample from White Oak Creek. Initially, Terracon gauged the groundwater levels in the three on-site
monitoring wells. Depth to groundwater ranged from approximately 3.33 feet below top of casing
(btoc) in well MW-4/RW-4 to 5.56 feet btoc in the unknown well. No free product was encountered at
the site. Based on groundwater elevations and topography, the flow direction is generally to the
southwest towards White Oak Creek. After purging, water samples were collected from wells MW-
4/RW-4, MW-5/RW-5 and the unknown well. Terracon also collected one water supply well sample
(Pritchard Residence, 22 Cardie Lane) and one surface water sample (SW-2) from White Oak Creek.
The water samples were submitted for laboratory analysis of volatile organic compounds (VOCs) by
Standard Method 6200, including MTBE, IPE, and EDB.
According to the laboratory analytical report, benzene (72.5 micrograms per liter [µg/L]),
ethylbenzene (1590 µg/L), isopropylbenzene (88.4 µg/L), naphthalene (886 µg/L), n-propylbenzene
(292 µg/L), 1,2,4-trimethylbenzene (2,700 µg/L), 1,3,5-trimethylbenzene (795 µg/L), and xylenes
(5,164 µg/L) were detected in the unknown well at concentrations above their respective 15A NCAC
2L groundwater standards (2L standards). Benzene (3.4 µg/L) and naphthalene (24.8 µg/L) were
detected in well MW-5/RW-5 at concentrations above the 2L standards. Various other constituents
were detected in wells MW-4/RW-4 and MW-5/RW-5 at concentrations below their respective 2L
standards. No constituents of concern were detected above the Method Detection Limits (MDLs) in
the Pritchard water supply well. The surface water sample obtained from White Oak Creek had an
estimated concentration for 1,2,4-trimethylbenzene at 0.37J µg/L. At the present time, no 15A
NCAC 2B surface water quality standard is established for 1,2,4-trimethylbenzene. The constituent
concentrations in the unknown well appear to be relatively stable while concentrations appear to be
increasing in well MW-5/RW-5.
Based on information obtained during the completion of these assessment activities, Terracon
provides the following conclusions and findings.
Free product was not encountered at the site.
No constituents of concern were detected above Gross Contamination Levels (GCLs).
Benzene, ethylbenzene, isopropylbenzene, naphthalene, n-propylbenzene, 1,2,4-trimethylbenzene,
1,3,5-trimethylbenzene, and xylenes were detected in the unknown well at concentrations above their
respective 2L standards. Benzene and naphthalene were also detected in well MW-5/RW-5 at
concentrations above the 2L standards.
The constituent concentrations in the unknown well appear to be relatively stable while
concentrations appear to be increasing in well MW-5/RW-5.

Benzene (72.5 µg/L) and toluene (593 µg/L) concentrations detected in the unknown well exceed the
15A NCAC 2B surface water quality standards. The unknown well is located approximately 145 feet
east of White Oak Creek.
Various other constituents were detected in monitoring wells MW-4/RW-4 and MW-5/RW-5 at
concentrations below their respective 2L standards.
No target analytes were detected in the Pritchard water supply well above the MDLs.
The surface water sample obtained from White Oak Creek had an estimated concentration for 1,2,4-
trimethylbenzene at 0.37J µg/L.
The estimated groundwater flow direction at the site is to the southwest towards White Oak Creek.
According to previous assessment reports, the site is provided potable water from a water supply well
located on the adjacent property to the south.
No active remedial activities are currently operational at the site.
Based on the findings of our assessment activities, the following comments and recommendations are
provided for the site.
Terracon recommends the on-site wells, the Pritchard water supply well and White Oak Creek be
sampled on a semi-annual basis.
Terracon recommends installing an O-Sox insert into MW-Unknown and MW-5/RW-5.
C. SITE HISTORY AND CHARACTERIZATION
The purpose of this report is to evaluate the current status of groundwater quality at the Rainbow
Pantry #5 site. Terracon completed this report to summarize the findings of assessment activities
performed on January 22, 2020. The site is located at 1833 Elk Park Highway in Newland, Avery
County, North Carolina (Figure 1). This Subsequent Monitoring Report was prepared for the site in
response to a request by NCDEQ Incident Manager, Mr. Scott Ryals with the Division of Waste
Management, State Lead Program.
The Subsequent Monitoring Report was prepared in general accordance with the 15A NCAC 2L.0115
regulations and the NCDEQ Underground Storage Tank (UST) Section Guidelines for Assessment
and Corrective Action for UST Releases, dated July 15, 2008, revised December 2013, under the
supervision of Mr. Christopher L. Corbitt, a North Carolina registered professional geologist (North
Carolina License No. 1015).
C.1 Site Setting
The site is located within a rural residential area of northwestern North Carolina. Specific land uses
are further described in Section C.6.

C.2 Release Summary
Based on limited regulatory file review information, an apparent release was reported on December
5, 1988 by the property owner when gasoline was discovered in an on-site vapor monitoring well
(leak detection monitoring) and evidence of gasoline was observed seeping into White Oak Creek
which is located approximately 80 feet west of the tank basin. As a result of the detected release,
multiple monitoring wells and recovery wells were installed on the site in 1989 by Delta.
The release at the site was controlled initially by a pump and treat system installed by Delta. The
remediation system suffered from multiple operations/maintenance issues to the extent that Delta
replaced the pump and treat system with an air sparge system that was activated on October 29,
1997. Reportedly, the air sparge system continued sporadic operations until approximately 2016
when Gipe & Associates (Gipe) transitioned remedial activities to natural attenuation monitoring.
Based on our observations and historical information, two gasoline USTs, a 4,000-gallon diesel UST
and a heating oil UST (unknown capacity) are apparently maintained on the property at the present
time. Historical UST information is provided in Table 1.
C.3 Previous Investigations
According to a Pollution Incident Reporting Form submitted to the NCDEQ by the property owner
(MD Ledbetter Oil Company) in December 1988, gasoline was discovered in an on-site vapor
monitoring well (leak detection monitoring) and evidence of gasoline was observed seeping into
White Oak Creek which is located approximately 80 feet west of the tank basin. After the release
incident was reported, Delta began assessment/remediation activities at the site by installing eight
groundwater monitoring wells and two recovery wells in 1989. Analytical results from a sampling
event in February 1989 indicated benzene and MTBE were detected in monitoring well MW-5/RW-5
at levels exceeding the GCLs while other gasoline constituents exceeded their respective 2L
groundwater standards in monitoring wells MW-4/RW-4 and MW-5/RW-5. Petroleum constituents
were also detected below the 2L standards in well MW-6.
In August 1991, Delta began operations of a pump and treat groundwater recovery system at the
site. The remediation system included four recovery wells (RW-1, RW-2, MW-4/RW-4 and MW-
5/RW-5). Analytical results from August 1991 indicated petroleum constituents exceeded the GCLs
in wells MW-2, MW-5/RW-5 and RW-1. Various petroleum constituents exceeded the 2L standards
in wells MW-4/RW-4, MW-7 and RW-2. Petroleum constituents were detected in well MW-8 at
concentrations below their respective 2L standards. The groundwater recovery system was
reportedly deactivated in December 1996 due to multiple system maintenance issues resulting in a
lack of improvement of the water quality at the site. After conducting a pilot study, Delta replaced the
pump and treat system with an air sparge system that was activated on October 29, 1997.
Reportedly, the air sparge system continued sporadic operations until approximately 2016.
A tank closure report prepared by Tank Removal Service, Inc. in February 1999 indicated a 1,000-
gallon kerosene UST was removed from the site. Soil samples collected from the tank basin were

transported to PAR Laboratories, Inc. for laboratory analysis. The analytical results indicated no
evidence of a release in the soils beneath the former tank. Due to reporting inconsistencies, the
closure report was deemed unsatisfactory by the NCDEQ and no incident closure letter was issued
by the NCDEQ. No additional regulatory information was provided regarding the status of closure for
the kerosene UST.
A second on-site UST (7,500-gallon gasoline tank) was reportedly removed from the site in May
2010 by Southeastern Geological. The UST Closure Report dated May 13, 2010 indicated the UST
was removed on April 20, 2010. Analytical results from the tank closure activities indicated Total
Petroleum Hydrocarbons were not detected above laboratory reporting limits. The former location of
the 7,500-gallon UST as noted in the Southeastern Geological report is apparently occupied by an
underground tank based on Terracon’s observations at the site.
Gipe & Associates, PA (Gipe) conducted various groundwater monitoring events at the site. The last
event occurred in October 2016. Gipe obtained water samples from monitoring wells MW-6 and MW-
9, former recovery wells RW-2, MW-4/RW-4 and MW-5/RW-5 and from two nearby water supply
wells on the Pritchard and Buchanan properties. Gipe indicated certain wells (MW-1, MW-3 and MW-
7) were destroyed or not found. Analytical results indicated petroleum constituents were detected in
wells MW-4/RW-4 and MW-5/RW-5 above 2L standards. No constituents were detected in the water
supply wells. Gipe also indicated the air sparge system would be deactivated and the site would
transition to natural attenuation monitoring.
Terracon conducted two groundwater sampling events in March 2019 and August 2019 to evaluate
the groundwater and surface water conditions at the site. Terracon was unable to locate wells MW-1,
MW-2, MW-6 and MW-9 during the sampling events but identified an unknown well located near the
former diesel/kerosene dispenser at the southeastern corner of the building. Analytical results
indicated benzene, ethylbenzene, isopropylbenzene, naphthalene, n-propylbenzene, toluene, 1,2,4-
trimethylbenzene, 1,3,5-trimethylbenzene, and xylenes were detected in the unknown well and
benzene and naphthalene was detected in well MW-5/RW-5 above their respective 2L standards.
C.4 Water Supply Wells
Three water supply wells were identified in the vicinity of the release as reported by Gipe in the 2016
monitoring report. The wells are identified as Site SW (site), Pritchard SW and Buchanan SW. The
Site SW well is currently disconnected. The Pritchard SW well is located south of the site and
reportedly provides potable water to the site. The location and status of the Buchanan SW well is
unknown. Water supply well information is summarized in Table 2.
C.5 Surface Water
White Oak Creek is located along the western boundary of the site. Surface waters near the site are

C.6 Land Use Information
The site is currently occupied by a convenience store with fueling services that appeared to be
closed during our site visit. The site is bound to the north by Turbyfill Road and Blue Ridge Propane,
to the east by Elk Park Highway, a vacant commercial building and residences, to the south by
residences, and to the west by White Oak Creek and residences. The site and surrounding
properties are depicted on Figures 1 and 2.
D. ASSESSMENT INFORMATION
D.1 Site Geology and Hydrogeology
The following resources were reviewed to evaluate site-specific geological and hydrogeological
characteristics.
Newland, North Carolina, USGS 7.5-minute topographic map, dated 1994 (Figure 1).
Geologic Map of North Carolina, dated 1985.
The Geology of the Carolinas, Carolina Geological Society Fiftieth Anniversary Volume, edited by J.
Wright Horton, Jr., and Victor A. Zullo, The University of Tennessee Press, dated 1991.

Conservation Service, Web Soil Survey via the Internet, http://websoilsurvey.nrcs.usda.gov/app/.
The site is located within the Grandfather Mountain Window (GMW) of the Blue Ridge Physiographic
Province. The Grandfather Mountain Window formed by thrust faulting creating a nonconformity of
older Proterozoic rocks (gneiss) overlying younger Pre-Cambrian rocks (meta-greywackes). Within
the GMW, the older rocks have been eroded exposing the younger aged rocks. The Blue Ridge
Province is a deeply dissected mountainous area with numerous steep mountain ridges,
intermontane basins and trench valleys. The Blue Ridge contains the highest elevations and the
most rugged topography in the Appalachian Mountain system of eastern North America.
In-place chemical and physical weathering of parent rocks typically form residual soils in the Blue
Ridge region. Weathering is facilitated by the presence of fractures, joints, and less resistant
minerals in the rock. In areas not altered by erosion, alluvial deposition or the activities of man, the
typical residual soil profile consists of clay-rich unconsolidated materials at the surface, transitioning
to sandy silts and silty sands at depth. Typically, the boundary between soil and rock is not sharply
defined. This transitional zone is termed “partially weathered rock” or saprolite. Information obtained
from the Web Soil Survey for Avery County, depicts soils at the site as Nikwasi loam (NkA) and
Whiteoak fine sandy loam (WkC).
In the Blue Ridge region, groundwater generally occurs in pore spaces within soils and in the
structural features present in the underlying rock (i.e. joints, fractures, and faults). Recharge to the
water table is primarily by precipitation infiltrating the surficial soils and percolating downward under
Rainbow Pantry #5

Incident No. 3856

Responsive ■ Resourceful ■ Reliable 8
the influence of gravity to the water table (vadose zone). Typically, the water table is not a level
surface, but a subdued reflection of the land surface. The depth to the water table is not consistent
and is dependent upon several factors that include the amount of rainfall, permeability of the soil, the
extent of fracturing in the underlying rock and the influences of groundwater pumping. Groundwater
typically flows in directions parallel to the ground surface and under the influence of gravity, migrates
to discharge points such as surface water features, the toes of slopes or natural springs.
Fluctuations in the depth of the water table can be expected depending on variations in precipitation,
surface water run-off and other factors not evident at the time of our subsurface exploration.
Normally, the highest levels of the water table occur in late winter and spring and the lowest levels
occur in the late summer and fall. Based on an interpreted groundwater flow direction from historical
data, groundwater is expected to flow to the southwest from the site.
D.2 Sampling Activities
D.2.1 Free Product Evaluation
Free product was not encountered at the site.
D.2.2 Groundwater Sampling Activities
Terracon mobilized to the site on January 22, 2020 to conduct groundwater sampling activities at
monitoring wells MW-4/RW-4, MW-5/RW-5, an unidentified well located near the southeastern
corner of the store building (MW-Unknown Well), collect one surface water sample (SW-2) from
White Oak Creek, and collect one water supply well sample (WSW) from the Pritchard Residence
(22 Cardie Lane).
Initially, Terracon gauged the groundwater levels in the wells. Depth to groundwater ranged from
approximately 3.33 feet below top of casing (btoc) in well MW-4/RW-4 to 5.56 feet btoc in the
unknown well. Based on groundwater elevations and topography, the flow direction is generally to
the southwest towards White Oak Creek. After purging, water samples were collected from wells
MW-4/RW-4, MW-5/RW-5 and the unknown well. Terracon also collected one surface water sample
(SW-2) downstream of the on-site building from White Oak Creek and one water supply (WSW)
sample from the Pritchard Residence (22 Cardie Lane). The groundwater and surface water samples
were placed in laboratory-supplied glassware, labeled and stored in an ice-packed cooler and were
submitted to Pace Analytical Laboratory in Huntersville, North Carolina for laboratory analysis of
volatile organic compounds (VOCs) by Standard Method 6200, including MTBE, IPE, and EDB. A
copy of Terracon’s field notes is included in Appendix B. Current and historical groundwater depth
measurements are provided in Table 4.
