◼ Ten (10) petroleum-related constituents were detected in monitoring wells MW-2, MW-3,
and/or MW-5 at concentrations that exceeded their respective Title 15A North Carolina
Administrative Code Subchapter 2L Groundwater Standards (2L standards).
◼ A Gross Contamination Level (GCL) exceedance for benzene was detected in MW-5. GCL
exceedances of benzene were historically detected in MW-5 from September 2014 to November
2018.
◼ Measurable thicknesses of free product were not observed in the monitoring wells. Free product
thicknesses have not historically been identified at the site; however, concentrations of petroleum
constituents in monitoring wells MW-3 and MW-5 are indicative of the presence of residual light
non-aqueous phase liquid (LNAPL).
◼ Surficial groundwater is estimated to flow toward the south.
◼ The contaminant plume has not been delineated to the north; however, the site is bounded to the
north by Hillsborough Street, which is a topographic high and a likely groundwater divide.
◼ Three potable water supply wells were identified within 1,000 feet of the source area. WSW-1,
WSW-2, and WSW-3 which are located on Singleton Street and are approximately 880, 970,
and 950 feet east-southeast of the source area, respectively. Municipal water is reportedly
available to the site and properties located within 1,000 feet of the source area with the
exception of properties located along Singleton Street.
◼ The nearest surface water feature is an unnamed, intermittent tributary of Walnut Creek, which
is situated approximately 400 feet south of the source area.
◼ Petroleum constituents were not detected above laboratory reporting limits within WSW-1,
WSW-2, and WSW-3.
C. SITE HISTORY AND CHARACTERIZATION
The purpose of this report is to evaluate the current status of the groundwater quality at Former
Annie Sprinkles Property site. Terracon completed this report to summarize the findings of
assessment activities performed on February 12, 2020 at the site located at
6319 Hillsborough Street in Raleigh, Wake County, North Carolina (Figure 1). This Subsequent
Monitoring report was prepared for the site in response to a request by the Incident Manager, Mr.
Mark Petermann, with the NCDEQ 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. Donald R. Malone, a North Carolina registered professional engineer
(North Carolina Professional Engineering License No. 20195).

C.1 Site Setting
The Former Annie Sprinkles Property site is located at 6319 Hillsborough Street in Raleigh, Wake
County, North Carolina (Figure 1) and is comprised of approximately 1.63-acres. The site includes
an approximately 545-square foot sales office building for Java Auto Sales with the remainder of the
site comprised of landscaping, asphalt-paved parking and driveway areas and wooded land.
The land use in the surrounding area is generally commercial/industrial and residential. The site is
bound by Hillsborough Street and a railroad right-of-way to the north; by Pine Stump Lane, the Old
Time Barbecue restaurant and a mobile home park to the east; by wooded land and a portion of a
townhome development to the south; and by the Secure Car Self Storage facility to the west.

The site is situated on the south side of an east-west oriented topographic divide. The divide likely
also serves as a groundwater divide and groundwater flow from the site based on topography is
anticipated to be towards the south.

C.2 Release Summary
The following underground storage tanks (USTs) were previously operated at the site:

UST Map ID Closed In-place Removed
4,000-gallon gasoline T-1 2001 2003
3,000-gallon kerosene/diesel T-2 Not Applicable 2003
4,000-gallon gasoline T-3 2001 2003
2,000-gallon gasoline T-4 Not Applicable 2003
1,000-gallon gasoline T-5 2001 2003

According to regulatory incident files, confirmation soil samples collected in November 2003 during
closure activities for USTs and their associated product lines revealed petroleum contamination
above the NCDEQ standards. A chronological summary of UST removal and subsequent
assessment activities at the site is discussed in the following section of the report.

C.3 Previous Investigations
During UST closure activities in 2003, a total of approximately 374 tons of petroleum-impacted soils
were excavated from the UST basin associated with USTs T-3, T-4 and T-5 (ECE, 2003).
Petroleum impacts were not observed in the UST basins containing the remaining USTs. Analytical
results from post-excavation confirmation soil sample indicated the presence of total petroleum
hydrocarbon (TPH) diesel range organic (DRO) and/or TPH gasoline range organics (GRO) at
concentrations exceeding the NCDEQ action level in the vicinity of tanks T-1, T-2 (eastern UST
basins), and the former dispenser island (ECE, 2003). The release was not reported to NCDEQ until
2013.

Subsequent investigations at the site since 2014 have included the installation and sampling of ten
monitoring wells, a receptor survey, sampling of water supply well WSW -1, and soil sampling.
Investigation results were used to generate a conceptual site model of current conditions, which is
included as Table 1.

A vapor intrusion study was also completed in April 2015, which included the collection of two indoor
and one background ambient air samples and the installation and sampling of two sub-slab soil
vapor points. Ambient air and sub-slab soil vapor results indicate that the petroleum vapor intrusion
pathway was incomplete; however, the 2015 vapor intrusion study did not include soil vapor
analyses for PCE.
An aggressive fluid-vapor recovery (AFVR) event was completed on monitoring wells MW-3 and
MW-5 in March 2016 in an attempt to extract free phase product. Approximately 600 gallons of free
product/groundwater mixture were removed from the site. The data indicated that the AFVR event
was not effective in removing a significant amount of residual NAPL.

In November 2018, Terracon mobilized to the site to conduct a soil investigation. Ten soil samples
were collected from depths between approximately 4 and 15 feet below land surface (bls) in the
area up-gradient of MW-5 to evaluate residual soil contamination at the site. Petroleum constituents
were identified above their soil-to-groundwater maximum soil contaminant concentrations (MSCCs)
in samples collected to the south of the former pump island and east of the former basin containing
Tanks 3, 4, and 5. The detected concentrations do not appear large enough to explain the
magnitude of benzene detections within groundwater at MW-5. The November 2018 soil data
suggest residual soil contamination at the site is located within the vadose zone.

In November 2018, Terracon also conducted a soil vapor investigation. One shallow exterior soil
vapor sample was collected from near the northwest corner of the Java Auto Sales building. Based
on field screening results, Terracon analyzed the sample for methane in addition to VOCs. Analytical
results indicated a concentration of 23% methane in the sample. Two VOCs, PCE and hexane, were
detected above laboratory reporting limits. The PCE concentration exceeded its NCDEQ Non-
Residential Vapor Intrusion Screening Level (VISL), and hexane was detected at an estimated
concentration above its Residential VISL. PCE has not historically been detected within groundwater
at the site; however, high concentrations of petroleum constituents in MW-3 and MW-5 requiring
dilution have resulted in elevated reporting limits for PCE.

Terracon conducted a limited review of historical and regulatory information for the site and
surrounding area to identify potential off-site sources of PCE (Terracon, 2019b). The review
identified several nearby facilities that may have utilized PCE, the closest of which (Linder Industrial
Machinery) is/was located approximately 350 feet northeast and topographically up- to cross-
gradient of the site. The review did not identify new information pertaining to the former on-site gas
station operations between 1960 and 2003 or Java Auto Sale’s current operations. It is not known

whether these operations have included the use of solvents containing PCE. Waste oil or non-
petroleum USTs have not been identified at the site.

The source of the methane in soil gas is not known with certainty; however, it is likely due to ongoing
in situ bioremediation of the fuel hydrocarbons in groundwater beneath the site that is now
anaerobic, due to oxygen update and subsequent depletion. Likewise, PCE is likely absent from
groundwater due to in situ reductive dechlorination reactions that occur during anaerobic conditions.
Other less probable sources of methane include the presence of buried municipal waste or a natural
gas pipeline leak. Numerous soil borings have been advanced on the site and evidence of buried
waste has not been reported or observed. Information indicating former landfilling or dumping
operations on the site has not been identified. Given that natural gas is primarily composed of
methane, a natural gas leak is also possible.

Most recently, Terracon conducted a subsequent monitoring event in August 2019 that identified 2L
standard exceedances for 10 petroleum constituents in MW-1, MW-2, MW-3, and/or MW-5. Three
water supply wells (WSW-1, WSW-2, and WSW-3) were also sampled in the August 2019 event
and petroleum constituents were not detected above laboratory reporting limits for each of the water
supply wells.

C.4 Water Supply Wells and Other Potential Receptors
Three water supply wells (WSW-1, WSW-2, and WSW-3) have been identified within 1,000 feet of
the source area, all of which have been confirmed to be an active potable wells). WSW-1, WSW-2,
and WSW-3 are situated approximately 880, 970, and 950 feet east-southeast the source area,
respectively. The Mann’s (owners of 200 Singleton Street property/WSW-9) previously indicated that
the residences located along Singleton Street (WSW-1 through WSW-14) are not connected to the
municipal water system and utilize private water supply wells and septic systems. The water supply
wells are located down-gradient of the site based on groundwater flow in the surficial aquifer.
Municipal water is provided by the City of Raleigh Public Utilities Department to the site and
properties located within 1,000 feet of the source area except for those located along Singleton
Street. Results of the water supply well inventory are presented in Table 2 and well locations are
depicted on Figure 3.

The nearest surface water feature is an unnamed tributary of Walnut Creek, which is situated
approximately 400 feet south of the source area. The tributary is not shown on Figures 1 or 2.

D. ASSESSMENT INFORMATION
D.1 Groundwater Sampling Activities

D.1.1 Free Product Evaluation
Measurable thicknesses of free product were not observed in the monitoring wells during this
sampling event. Free product thicknesses have not historically been measured at the site.

D.1.2 Depth to Groundwater Evaluation
Terracon mobilized to the site on February 12, 2020 to conduct groundwater sampling as requested
by the NCDEQ. Prior to sample collection, Terracon gauged the groundwater elevations in the
monitoring wells (MW-1 through MW-11). The approximate locations of the wells are shown on the
Site Map (Figure 2). Depth to groundwater measurements ranged from approximately 1.98 to 16.72
feet bTOC. Current and historical groundwater elevation measurements are provided in
Table 3. Surficial groundwater is estimated to flow toward the south based on current groundwater
elevations. The estimated flow direction is generally consistent with historical groundwater flow
direction. A groundwater elevation map is included as Figure 5. Copies of field notes are provided
in Appendix A.

D.1.3 Monitoring Well Sampling Activities
Terracon sampled eleven monitoring wells (MW-1 through MW-11). A field blank (FB-01) was also
collected during the sampling event. Copies of field notes are provided in Appendix A.

Prior to sampling, the wells were purged with a peristaltic pump using low flow sampling techniques
(i.e., <200 milliliters per minute). Field parameters consisting of pH, temperature,
oxidation-reduction potential (ORP), dissolved oxygen, and conductivity were measured at each of
the well locations. After stabilization of pH and conductivity, the groundwater sample was collected
directly into laboratory-supplied glassware, labeled and stored in an ice-packed cooler. The
samples, along with chain-of-custody documentation, were delivered to Shealy Environmental
Services, Inc. of West Columbia, South Carolina for analysis of VOCs by EPA Method 6200B
including xylenes, MTBE, ethylene dibromide (EDB), and di-isopropyl ether (IPE).

D.1.4 Water Supply Well Sampling Activities
Terracon sampled three water supply wells (WSW-1, WSW-2, and WSW-3). The water supply well
samples were obtained by allowing water to flow from an exterior spigot for approximately 15
minutes prior to collecting a fresh sample from the well. Flow from the spigot was reduced when the
sample was collected.

The groundwater samples were placed in laboratory-supplied glassware, labeled and stored in an
ice-packed cooler. The samples, along with chain-of-custody documentation, were delivered to
Shealy Environmental Services, Inc., in West Columbia, South Carolina for analysis of VOCs by
EPA Method 6200B including xylenes, MTBE, IPE, and ethylene dibromide (EDB).

D.2 Analytical Results

Based on the laboratory analytical reports, 10 petroleum-related constituents were identified at
concentrations above 2L standards in monitoring wells MW-2, MW-3, and/or MW-5. A Gross
Contamination Level (GCL) exceedance for benzene was detected in MW-5.

Petroleum constituents were not detected above 2L standards in the remaining monitoring wells or
above their laboratory reporting limits in the field blank. Compounds were not detected above
laboratory reporting limits in the water supply well samples WSW-1, WSW-2, and WSW-3.

The groundwater analytical results are summarized on Table 5 and Figure 5. An isoconcentration
map for benzene is provided as Figure 6. The map depicts the estimated lateral extent of benzene
in the groundwater. The source area for the elevated concentrations in monitoring well MW-5 is
likely the former dispenser area and/or former western UST basin. The contaminant plume has not
been delineated to the north; however, the site is bounded to the north by Hillsborough Street, which
is a topographic high and a likely groundwater divide.

Copies of the laboratory analytical reports are provided in Appendix B.

The data in the field logs in Appendix A indicate low oxygen concentrations and ORP levels in
several of the wells (MW-2, MW-3, MW-5) that have elevated concentrations of petroleum
constituents. Depleted oxygen concentrations in these wells are indicators of in situ bioremediation
of the fuel hydrocarbons in groundwater.
E. CONCLUSIONS AND RECOMMENDATIONS
Based on information obtained during the completion of groundwater monitoring activities, Terracon
provides the following conclusions and findings.

◼ Ten (10) petroleum-related constituents were detected in monitoring wells MW-2, MW-3,
and/or MW-5 at concentrations that exceed their respective Title 15A North Carolina
Administrative Code Subchapter 2L Groundwater Standards (2L standards).
◼ A Gross Contamination Level (GCL) exceedance for benzene was detected in MW-5. GCL
exceedances of benzene were historically detected in MW-5 from September 2014 to November
2018.

available to the site and properties located within 1,000 feet of the source area with the
exception of properties located in the eastern vicinity along Singleton Street. The nearest
surface water feature is unnamed tributary of Walnut Creek, which is situated approximately
400 feet south of the source area.
◼ The low oxygen concentrations and ORP levels in several of the wells (MW-2, MW-3, MW-5)
indicate the depletion of oxygen from in situ bioremediation of the fuel hydrocarbons.
◼ Petroleum constituents were not detected above laboratory reporting limits within WSW-1,
WSW-2, and WSW-3.

Based on the data presented in this Subsequent Monitoring report, Terracon recommends the
following activities be completed at the site.

◼ Semi-annual sampling of the monitoring well network to monitor groundwater conditions.
◼ Collection of a surface water sample from the unnamed, intermittent tributary of Walnut Creek
located approximately 400-feet south of the source area.
◼ Additional vapor intrusion evaluation should be conducted to assess temporal trends in
petroleum vapor intrusion risk. The evaluation should include sub-slab samples from beneath the
Java Auto Sales building.
◼ Complete a Corrective Action Feasibility Study to evaluate possible remediation methods for
impacted groundwater associated with the former on-site petroleum UST system. Methods under
consideration would include low-cost in situ remediation strategies such as the injection of
oxygen-release compounds that will replace the oxygen lost from groundwater due to naturally
occurring bioremediation of petroleum hydrocarbons. We would also consider other injection
amendments that utilize alternative electron acceptors (e.g., sulfate and nitrate) to drive
anaerobic bio-oxidation reactions. The overall intent of the corrective actions would be to lower
groundwater concentrations in the source area, and subsequently, downgradient of the source
area.

◼ The NCDEQ Inactive Hazardous Sites Branch (IHSB) should be informed of the PCE detected
within soil vapor.
◼ Attempt to obtain well construction details for supply wells WSW-1, WSW-2, and WSW-3 by
contacting the Wake County Health Department and/or contacting property owners and attempt
to measure the depth to the bottom of the wells.
◼ Install three deep monitoring wells paired with existing shallower wells (MW-5, MW-8, and
MW-10) to vertically delineate the plume.
◼ Contact the City of Raleigh to attempt to connect houses within 1,000 feet to public water and
then abandon water supply wells WSW-1, WSW-2, and WSW-3.

Indoor Air Concentrations > VISLs?Concentrations above indoor air screening levels but data indicates PVI pathway incomplete; however,
indoor air samples not analyzed for PCE.
Is the VI Pathway Complete?Paired sub-slab and ambient air data indicates petroleum VI not a concern; however, temporal variations
in petroleum concentrations in soil vapor have not been evaluated
Soil excavated (374 tons) from western UST basin during UST removal in 2003. Confirmation samples
contained TPH GRO & DRO concentrations above NCDEQ Action Levels. Subsequent soil investigations
indicate residual soil impacts below residential MSCCs
An AFVR event was completed on monitoring wells MW-3 and MW-5 in March 2016. Data indicated that
AFVR was not effective in removing a significant amount of residual NAPL.
Number within 250 feet None identified
Number within 250-500 feet None identified
Number within 500-1,000 feet 3 (2 known to be potable, one assumed to be potable)
Unnnamed intermittent stream 400 ft south; groundwater plume delineated to south
Paired sub-slab and ambient air data indicates petroleum VI not a concern; however, PCE detected above
Non-Residential VISL in exterior soil vapor.
Restrict to Commercial/Industrial Use
Unsaturated soil not impacted above residential MSCCs; can close without soil restriction
NAPL and/or >GCLs Monitored natural attenuation until concentrations consistently remain below GCLs
Water Supply Wells Vertically delineate plume or connect to public water
Intermittent stream located 400 ft to south; monitored natural attenuation until groundwater
concentrations are below 10 times the NCAC 02B Surface water standards.
Additional evaluation of VI pathway is necessary to evaluate temporal variation.
