5 Deep Aquifers in the Coastal Plain Physiographic Region
The subject site is not located in the Coastal Plain Physiographic Province.
6 Subsurface Structures
Overhead electrical and phone utility lines are located at the subject site. Subsurface water
and sewer lines are at the site and along the Stratford Court right-of-way. Subsurface utilities
were not identified in the location of the former UST systems.
7 Property Owners and Occupants
Carol Page Armstrong Revocable Trust currently owns the subject property. Adjacent
parcels are developed with commercial use properties. The names and addresses of the
adjacent property owners are provided in Table B-6 and referenced on Figure 3.
D SITE GEOLOGY AND HYDROGEOLOGY
According to the Geologic Map of North Carolina (1985), the subject property is situated in
the Milton Belt of the Piedmont Physiographic Province of North Carolina. The site is located
in an area underlain by biotite gneiss and schist. In the Piedmont Physiographic Province,
groundwater generally occurs under water-table conditions and is stored in the pore space
between individual grains of residual soil and in the fractures within the underlying parent
rock. Due to the intense shearing associated with the thrust faulting in the area, it can be
expected that the fractures play a major role in the flow of groundwater in the subsurface.
Recharge to the water table is primarily by precipitation infiltrating the upper soils and
percolating downward, under the influence of gravity, to the groundwater table. Typically, the
water table is not a level surface, but a subdued reflection of the land surface. However, the
depth to the water table is not constant, and depends on many factors, which include the amount
of rainfall, the permeability of the soil, and the amount of groundwater being pumped in the
area.
Based on our review of the topographic map and on-site observation, the site slopes gently
to the south-southeast. Groundwater generally flows in directions sub-parallel to the ground
surface slopes and under the influence of gravity toward points of discharge such as creeks,
swamps, drainage swales, or pumped groundwater wells. Based on topographic inference,
groundwater beneath the site most likely flows to the south-southeast toward a railroad right-
of-way. Little Creek is located approximately 1,400 feet to the northwest of the source area
(Figure 1). Note that the area is highly developed and influenced by various stormwater
management structures.

E SAMPLING RESULTS
1 Soil
Groundwater was encountered during the over-excavation activities and, therefore, soil
samples were not collected during the assessment. Note that groundwater levels within the
site monitoring wells ranged from approximately 22 – 23 feet bls.
2 Groundwater
Two Type II permanent monitoring wells were installed during the LSA activities using a
truck-mounted drill rig and hollow-stem augers on May 18, 2020 by 3D Environmental
Investigations, LLC (3D). 3D installed two, two-inch monitoring wells (MW-1 and MW-2)
to approximate depths of 35 and 30 feet bls, respectively, with 15 feet of 0.01 slotted
Schedule 40 PVC screen using the hollow stem auger drilling method. Progress developed
and sampled the monitoring wells on May 18, 2020 following installation. The groundwater
samples were collected using a disposable bailer and new length of cord and transferred to
laboratory containers. The groundwater samples collected from monitoring wells MW-1 and
MW-2 were analyzed for volatile organic compounds (VOCs) using EPA Method 602, for
sei-volatile organic compounds (SVOCs using EPA Method 625, and for volatile and
extractable petroleum hydrocarbons (VPH and EPH) using the Massachusetts Department
of Environmental Quality (MADEP) Method.
Laboratory analysis of the groundwater sample collected from monitoring well MW-1
detected naphthalene (78.2 µg/L), 2-methylnaphthalene (359 µg/L), 1-methylnaphthalene
(312 µg/L), C9-C18 Aliphatics (50,280 µg/L), and C9-C22 Aromatics (18,130 µg/L) at
concentrations exceeding their respective North Carolina 2L Groundwater Quality Standards
(NC2LGWQS). None of the concentrations of targeted compounds detected exceed the
applicable applicable Gross Contamination Level (GCL).
Laboratory analysis of the groundwater sample collected from monitoring well MW-2
detected naphthalene (82.0 µg/L), 1-methylnaphthalene (99.8 µg/L), 2-methylnaphthalene
(139 µg/L), C9-C18 Aliphatics (2,470 µg/L), and C9-C22 Aromatics (1,647 µg/L) at
concentrations exceeding their respective NC2LGWQS. None of the concentrations of
targeted compounds detected exceed the applicable GCL.
A summary of the groundwater analytical results is included in Table B-4. Copies of the
laboratory data sheets and chain-of-custody record are included in the Appendix D. The
groundwater sample was collected using the methods described in Appendix B.
F CONCLUSIONS AND RECOMMENDATIONS
Based on the results of the receptor survey and groundwater sampling activities, Progress
makes the following conclusions and recommendations:
1.The site meets the criteria for an Low Risk site based on the absence of detected
concentrations of targeted petroleum compounds exceeding the applicable Gross
Contamination Level, a surface water feature not being identified within 500 feet, and water-

Office of the North Carolina Department of Environmental Quality (NCDEQ), Division of
Waste Management, UST Section.
G FREE PRODUCT INVESTIGATION/RECOVERY
Free product was not detected in the monitoring wells during the May 2020 sampling event.
H SITE HISTORY
Progress Environmental Group, Inc. (Progress) was contracted by Page Distributing Company, Inc.
to conduct underground storage tank (UST) closure activities at the Page Distributing Company Site
located at 150 Stratford Court in Winston-Salem, Forsyth County, North Carolina (Figure 1). The
site consists of a former bulk oil facility which stored petroleum products in USTs for distribution
and retail sale. At the time of the removal the site was not an operating facility. The site is located
in a generally commercial area of Winston-Salem.It is likely that the surrounding properties are
served by the Winston-Salem municipal water-supply system. The closure activities included the
removal of three gasoline USTs, two new oil USTs, one diesel fuel UST, one waste oil UST,
associated piping, and fuel dispensers. The site is depicted on Figure 2.
On September 30, 2019 through October 4, 2019 Stewarts Grading and Hauling excavated the
overburden soil from the vicinity of the USTs using a trackhoe. Progress personnel provided
oversight during excavation activities. The USTs were encountered approximately three to four feet
below land surface (bls). Stewarts Grading and Hauling evacuated the fluids (approximately 1,525
gallons) via a vacuum truck and tanker prior to the UST removals. Progress did not note significant
damage or perforations on the USTs. The USTs were transported off-site via flatbed trailer to a metal
recycling facility.
The excavation for the gasoline USTs was approximately 36 feet by 27 feet by 13 feet deep.
Petroleum odors were noted in the vicinity of the fillports at the time of removal. The excavation for
the new oil USTs was approximately 22 feet by 25 feet by 13 feet deep. The excavation for the
diesel fuel UST was approximately 25 feet by 12 feet by 13 feet deep. Noticeable petroleum odors
were noted during the excavation of the diesel fuel UST. The excavation of the waste oil UST was
approximately 21 feet by 9 feet by 9 feet deep.
A total of nine soil samples were obtained beneath the gasoline USTs from the bucket of the trackhoe
for analysis for gasoline range total petroleum hydrocarbons (TPH-G) (T-1-1, T-1-2, T-1-3, T-2-1, T-
2-2, T-2-3, T-3-1, T-3-2, and T-3-3). Progress collected a total of six soil samples beneath the two
8,000-gallon new oil USTs (T-4-1, T-4-2, T-4-3, T-5-1, T-5-2, and T-5-3) from the bucket of the
trackhoe for analysis for diesel range total petroleum hydrocarbons (TPH-D). Progress collected a total
of three soil samples beneath the 8,000-gallon diesel UST (T-6-1, T-6-2, T-6-3) from the bucket of the

trackhoe for analysis for total petroleum hydrocarbons as TPH-G and TPH-D. Progress collected a
total of two soil samples beneath the 2,000-gallon waste oil UST (T-7-1 and T-7-2) from the bucket of
the trackhoe for analysis for volatile organic compounds, semi-volatile organic compounds, volatile
and extractable petroleum hydrocarbons, and lead and chromium. Progress collected a total of 13 soil
samples beneath the fuel distribution lines (L-1 through L-13) from the bucket of the trackhoe for
analysis for TPH-G, with samples collected from beneath distribution lines associated with the diesel
fuel UST also analyzed for TPH-D. Progress collected a total of 4 soil samples beneath the dispensers
(D-1 through D-4) from the bucket of the trackhoe for analysis for TPH-G, with samples collected from
beneath the dispensers associated with the diesel fuel UST also analyzed for TPH-D. After obtaining
each soil sample, the soil samples were transferred to laboratory-prepared containers and immediately
placed on ice. A label with the facility name, soil sample number, date and time of sampling, and
parameter to be analyzed was affixed to each container for identification. New disposable latex gloves
were used to maintain sample integrity during the sampling process. Proper preservation methods and
chain-of-custody procedures were followed throughout the sampling process.
Progress supervised soil excavation activities on November 11 through 14, 2019 following removal
of the UST system. Soil excavation activities were completed by Stewarts Grading and Hauling
utilizing a trackhoe. Accessible contaminated soil was loaded into awaiting dump trucks and
transported to the AES, Inc. facility in Thomasville, North Carolina. Approximately 624.24 tons of
contaminated soil were excavated in an effort to remove the impacted soil. The over-excavation of
contaminated soil proximal to the diesel fuel UST was an irregularly shaped polygon, with a larger
area in the vicinity of the southern end of the UST and former dispenser location. The excavation of
the former UST area had an approximate width of 16 feet on the northern end and 20 feet on the
southern end, an approximate length of 31 feet, and a depth of approximately 20 feet bls. The over-
excavation proximal to the release identified along the diesel fuel dispensing line was approximately
15 feet by four feet and extended less than a foot beneath the former product line. The over-
excavation in the area of the former diesel fuel dispenser area had an approximate width of 15 feet
by 15 feet and a depth of approximately 25 feet bls.
Progress collected soil samples from the sidewalls of the excavations (SW-1 through SW-10) and
from the base of the over-excavation proximal to the diesel fuel UST (B-1) to be analyzed for volatile
organic compounds (VOCs) by EPA Method 8260/5035, for semi-volatile organic compounds using
EPA Method 8270, and for volatile and extractable petroleum hydrocarbons (VPH and EPH) by the
Massachusetts Department of Environmental Protection (MADEP) Methods. The sidewall soil
samples were collected from an approximate depth of 14 feet bls. The soil sample collected from the
base of the excavation in the areas of the identified soil contamination at the time of the UST Closure
were collected from an approximate depth of 20 feet bls. Progress collected soil samples Truck 1
through Truck 39 from the excavated soil for disposal purposes. The disposal soil samples were
analyzed for TPH-G and TPH-D using the UVF Method by Redlabs mobile laboratory. The soil
samples were collected using the bucket of the trackhoe from soil being excavated for off-site
disposal.
The confirmation soil samples were appropriately packaged and delivered to Research and Analytical
Laboratories, Inc. (R&A) in Kernersville, North Carolina. Proper chain-of-custody procedures were
maintained throughout the sample collection and transportation process. Following the collection of
soil samples, Stewarts Grading and Hauling backfilled the excavation with imported fill material
from a nearby quarry.

Laboratory analysis of soil sample L-10 collected beneath the product line and soil sample T-6-1
collected beneath the diesel fuel UST detected TPH-G above the North Carolina Action Level of 50
mg/Kg. Laboratory analysis of soil samples T-6-1, T-6-2, and T-6-3 collected beneath the diesel fuel
UST detected TPH-D above the North Carolina Action Level of 100 mg/Kg. Laboratory analysis of
soil samples D-1 and D-2 collected beneath the diesel fuel dispensers detected TPH-D above the
North Carolina Action Level of 100 mg/Kg. Laboratory analysis of the remaining soil samples
collected from beneath the fuel distribution lines and dispensers did not exhibit concentrations above
the applicable standards.
Laboratory analysis of soil samples SW-1 and SW-6 collected from the sidewalls of the over-
excavation did not detect targeted compounds above their respective Soil-to-Groundwater Maximum
Soil Contaminant Concentrations (MSCCs) or Residential Soil Cleanup Levels. Laboratory analysis
of soil samples SW-7, SW-8, and SW-10 from the sidewalls and B-1 from the base of the over-
excavation of contaminated soil proximal to the former diesel fuel dispensing island detected at least
one targeted compound above its respective Soil-to-Groundwater MSCC and/or Residential Soil
Cleanup Level.
Groundwater was encountered in the over-excavation in the vicinity of the former diesel fuel
dispensers at a depth of approximately 24 feet bls in the open excavation. Therefore, a soil sample
was not collected from the base of the excavation in the vicinity of the former diesel fuel dispensers.
Free product was not observed during the UST removal activities.
Following the completion of the initial abatement activities, Progress concluded the following:
Progress supervised the removal of a total of seven USTs, associated fuel dispensing lines, and fuel
dispensers from the subject site.
Progress collected a total of nine soil samples beneath the three gasoline USTs (T-1-1, T-1-2, T-1-
3, T-2-1, T-2-2, T-2-3, T-3-1, T-3-2, and T-3-3). Progress collected a total of six soil samples
beneath the two 8,000-gallon new oil USTs (T-4-1, T-4-2, T-4-3, T-5-1, T-5-2, and T-5-3).
Progress collected a total of three soil samples beneath the 8,000-gallon diesel UST (T-6-1, T-6-2,
T-6-3). Progress collected two soil samples beneath the 3,000-gallon waste oil UST (T-7-1 and T-
7-2).
Laboratory analysis of the soil samples T-6-1 (18,500 mg/Kg), T-6-2 (14,700 mg/Kg), and T-6-3
(667 mg/Kg) collected beneath the diesel fuel UST indicated TPH-D concentrations in excess of
the North Carolina Action Level. Additionally, laboratory analysis of soil sample T-6-1 (82.0
mg/Kg) collected beneath the diesel fuel UST indicated a TPH-G concentration in excess of the
North Carolina Action Level.
Progress collected a total of 13 soil samples beneath the fuel distribution lines (L-1 through L-13).
Laboratory analysis of the soil samples collected from beneath the fuel distribution lines did not
exhibit detectable concentrations of TPH-G and/or TPH-D, except for line sample L-10 (94.1
mg/Kg TPH-G and 221 mg/Kg TPH-D).
Progress collected a total of 4 soil samples beneath the dispensers (D-1 through D-4). Laboratory
analysis of the soil samples D-3 and D-4 collected from beneath the gasoline dispensers did not
exhibit detectable concentrations of TPH-G. Laboratory analysis of the soil samples D-1 (22,300
mg/Kg) and D-2 (22,700 mg/Kg) collected beneath the diesel fuel dispensers indicated TPH-D
concentrations in excess of the North Carolina Action Level.
Based on the presence of notably contaminated soil, Progress supervised the over-excavation of
contaminated soil beneath the diesel fuel UST, fuel distribution lines, and former diesel dispensers.

Soil samples were screened using Redlabs mobile laboratory to complete the guided excavation.
Approximately 624.24 tons of petroleum-impacted soil were excavated from the site and
transported to an off-site permitted disposal facility.
Following the over-excavation of the contaminated soil, Progress screened the soil samples from
the sidewalls of the excavation via Redlabs mobile laboratory. Each of the soil samples selected
for laboratory analysis did not exhibit TPH as gasoline at concentrations exceeding the North
Carolina Action Level when analyzed using the UVF Method. Progress collected conformation
soil samples from the sidewalls and base of the over-excavations. Prior to collecting the soil
samples for confirmation sampling, Progress utilized the Redlabs mobile laboratory to screen the
soil samples for TPH-G and TPH-D. Laboratory analysis of soil samples SW-1 and SW-6 collected
from the sidewalls of the over-excavation did not detect targeted compounds above their respective
Soil-to-Groundwater Maximum Soil Contaminant Concentrations (MSCCs) or Residential Soil
Cleanup Levels. Laboratory analysis of soil samples SW-7, SW-8, and SW-10 from the sidewalls
of the over-excavation of contaminated soil proximal to the former diesel fuel dispensing island
detected at least one targeted compound above its respective Soil-to-Groundwater MSCC and/or
Residential Soil Cleanup Level.
Groundwater was encountered in the over-excavation in the vicinity of the former diesel fuel
dispensers at a depth of approximately 24 feet bls in the open excavation. Therefore, a soil sample
was not collected from the base of the excavation in the vicinity of the former diesel fuel dispensers.
Progress recommended submitting a copy of this report to the Winston-Salem Regional Office of the
NCDEQ.

APPENDIX B
STANDARD SAMPLING PROCEDURES
EXHIBIT A
Procedures for Developing the Monitoring Wells
Well development will be performed no sooner than 24 hours after well construction is completed.
Wells will be developed by bailing or pumping a minimum of five well-volumes of groundwater
from the well.
The turbidity, pH, specific conductivity, dissolved oxygen and temperature of the development
water will be measured and recorded, and used as an indicator parameter to determine the
completion of the development process.
EXHIBIT B
Procedures for Collecting Groundwater Samples
Each well will be purged of three standing well volumes prior to sample collection to remove
stagnant water from the well and well bore in an effort to collect samples that are representative of
the water quality in the formation surrounding each well.
Chemical preservatives, if applicable, will be added to sample bottles by the laboratory.
Sample bottles will be labeled prior to sample collection.
Sample bottles will be filled directly from the Teflon or disposable bailer. Volatile organic samples
will be collected first.
The pH, temperature, and specific conductance of the sample will be measured and recorded.
These measurements will be taken from a sample deposited in a separate container. Visual
characteristics of the sample, including insoluble materials, will be recorded.
Caps will be secured on bottles, bottle will be placed in plastic bags and the bags will be sealed.
Documentation, including Chain-of-Custody Record and laboratory analytical request form, will
be completed for all samples.
Samples will be packed in coolers with "bubble wrap" and ice packs for shipment.
Chain-of-Custody Record and analytical request form will be placed inside cooler sealed with
security tape.
Samples will be shipped via overnight express to the analytical laboratory within 24 hours
following collection.
Laboratory will be advised of each sample shipment.
