RE: Quantitative High Resolution Site Characterization Report
Wake Forest Deli & Grocery
711 N Main Street
Wake Forest, North Carolina
Dear Mr. Buchanan,

AST Environmental, Inc. (AST) appreciates the opportunity to collaborate with Withers Ravenel
and NCDEQ to complete the Quantitative High Resolution Site Characterization (qHRSC) at the
above referenced location. The proposed scope of work was to complete 6 soil borings to
approximately 55 ft-bgs. The overall goal of this qHRSC program is to:

1. Quantify the TVPH and benzene soil concentrations, on site and off.
2. Provide a visual interpolation of a high-resolution data set to aid in future investigation and
remedial activities.
3. Design a BOS 200+ injection plan to bring groundwater concentrations in compliance with
regulatory requirements.

This letter report provides a summary of field activities during the RDC and an overview of
analytical soil and groundwater data.

REMEDIAL DESIGN CHARACTERIZATION

On June 16, 2023 AST mobilized to the site to begin direct push drilling with the Geologic
Exploration (GEX) drilling team. During the RDC event, a total of 6 soil borings were advanced
via direct push drilling by GEX using their Geoprobe 3230. At each boring location, a 2.25 inch
diameter direct push, dual tube tooling was advanced in five foot runs. Samples were collected
every two feet beginning at PID or olfactory presence of hydrocarbon mass. All intervals were
logged for lithology and PID readings were collected to guide the sampling process. Soil samples
were collected and shipped to the RPI Project Support Laboratory in Golden, CO for VOC and
Total Volatile Petroleum Hydrocarbon (TVPH) analysis via EPA method 8260B. Soil data has
been tabulated and is included in the attachments as Table 1. Although this data is used for
injection design purposes, the lab is not a certified or accredited laboratory, this data should not
be used for regulator or compliance purposes.

Existing monitoring wells MW-03, MW-06, MW-07, MW-08, MW-09, and MW-12 were developed
and sampled. Groundwater samples were shipped to the RPI Project Support Laboratory in
Golden, CO for VOC and Total Volatile Petroleum Hydrocarbon (TVPH) analysis via EPA method
8260B, anions via EPA method 300.1 and dissolved gases via EPA method RSK 175.
Groundwater data has been tabulated and is included in the attachments as Table 2, Table 3,
and Table 4.

Groundwater in MW-03 and MW-07 contains benzene in concentrations greater than 5,000 ug/L,
and MW-08, MW-09, and MW-12 contain concentrations above 1 ug/L. Select results from the

RDC have been tabulated within this report and can be found below. According to the ITRC
LNAPL Guidance Document, TVPH concentrations indicative of residual LNAPL in the subsurface
are between 250 and 500 mg/kg, depending on the soil type. TVPH concentrations observed at
this site range from less than 0.5 to over ~4,500 mg/kg TVPH at RDC-05.

Boring logs for each location are included in Attachment B.

3-Dimensional Quantitative Model

The soil data collected from the RDC program was loaded into Ejlskov Environmental Site Model
(ESM), a proprietary data visualization and acquisition software developed by Ejlskov A/S, a RPI
Wake Forest Deli
September 8, 2023
Page 3

Group member. Once entered in the software, a 3-dimensional interpolation of the benzene and
TVPH soil data was produced by using the ESM inverse distance algorithm. From the review of
this data, 2-dimensional figures of the benzene and TVPH maximum soil concentrations, benzene
groundwater isoconcentration map, and cross sections of both contaminant plumes were created
and are included in the Figures attachment.

Conclusions and Recommendations

As indicated above, the ITRC LNAPL Guidance Document states that TVPH concentrations
indicative of residual LNAPL in the subsurface are between 250 and 500 mg/kg, depending on
the soil type. Based on the data collected during the RDC event and the subsequent interpolation
of the data, the subsurface distribution of residual LNAPL is confined to the area immediately
surrounding and below the former tank pit. In addition to the quantification of residual LNAPL
using the TVPH concentrations, the saturated benzene soil concentrations are also used for
determination of injection locations and depths in order to meet the groundwater standard. Using
the state of Washington three phase partitioning model
(https://www.ezview.wa.gov/Portals/_1987/Documents/Documents/WAC_173-340-
747_SoilDefaultHydrogeologicParameterData_2001.pdf), to be protective of groundwater at
5,000 ug/L benzene, soil concentrations of benzene must be below 2,050 ug/kg. Considering
detection limits for soil are at 0.5 ug/kg, AST has targeted benzene concentrations with reportable
concentrations in excess of 1 ug/kg or above the detection limit listed at or above 50 ug/kg.

Based on the data generated during this qHRSC, AST recommends that a BOS 200+ injection
program be considered to reach the groundwater goal of GCL’s at this site.

Based on the GCL remediation goal of 5,000 ug/L benzene, and the elevated soil mass present
in the injection area, a BOS 200+ plan has been completed that includes supplemental additives
to increase the rate of degradation on the activated carbon surface and prolong the ability of the
facultative microbes to continue the degradation process for years.

BOS 200+ INJECTION DESIGN – SEE ATTACHED FOR DESIGN LOADINGS & FIGURE FOR
LOCATIONS
BOS 200® provides the unique capability (Trap & Treat® process) to utilize two proven and
powerful technologies that rapidly and effectively remediate petroleum hydrocarbon sites:

1) Trapping of the contaminants via activated carbon adsorption.
2) Subsequent treatment via biological degradation within the BOS 200® matrix utilizing both
aerobic and anaerobic microbial processes.

The “Trap” provides the immediate mass reduction and plume control, while the “Treat” provides
the continued long-term remedial degradation using synergistic facultative bacteria. No other
activated carbon product can emplace a biological treatment mechanism on activated carbon for
injection; this intellectual property is protected by RPI patents. AST is designed by RPI as the
product design arm and distributor for the RPI Group.

BOS 200® is a fine-grained, dry material which consists of activated carbon, calcium sulfate,
nitrate, phosphate, and ammonia in a proprietary blend. It is 77% by weight activated carbon and
up to 19% gypsum. The gypsum component itself is 79% by weight sulfate, which translates to
approximately 15% by weight sulfate in BOS 200®. The product is mixed with water and a
facultative blend of aerobic and anaerobic microbes to create a solids suspension. This is now an
ideal environment for biological degradation, where hydrocarbons are adsorbed on to BOS 200®
particles made up of:
• Terminal Electron Acceptors: oxygen, nitrate, ammonia, and sulfate (primary)
• Micro- and Macro-Nutrients - phosphorus and nitrogen
• Aerobic and anaerobic blend of facultative microbes (over 27 species)

On flexibility, with BOS 200® product, the design approach can vary from a treatment objective
where complete and immediate contaminant mass removal from the groundwater is achieved, to
a partial contaminant mass reduction working in conjunction with biological degradation driving
the groundwater cleanup effort, or any combination somewhere in between. The end effect is that
the plume can be controlled in a short period of time and treatment can be extended over a longer
period.

The revised BOS 200® injection design has been prepared for each area using the following
approach/basis:

1. RDC and historical data from soil and groundwater sampling (i.e., analytical results, the
screened interval of the wells, the soil sampling depth intervals) were used to determine
the vertical and horizontal extent of impacts in each area.

2. Using the same data for each area a contaminant mass loading on a unit basis (lb.
benzene per ft3 of impacted media) was determined for each of the designated areas.

3. The contaminant mass loadings were then used to determine the BOS 200® loadings (lbs.
installed per ft3 of impacted media) necessary to remediate a specific depth interval within
each injection area. This is a balance between the need to have an immediate mass
reduction or to allow the biological process to be the controlling process. This is
specifically discussed for each area below.

4. Quarterly monitoring of the dissolved phase contaminant trends (BTEX, TVPH), along
with terminal electron acceptor consumption will dictate if/when a second additional
event occurs.

POST INJECTION SAMPLING

Following the injection, AST will collect groundwater samples from all of the monitoring wells
within the injection area prior to demobilizing. AST recommends performance progress
groundwater sampling events at intervals of one week, two weeks, one-month post injection and
quarterly until remediation goals are obtained. AST understands that this will be performed by
others. The performance samples can be sent to Remediation Products, Ince. Laboratory in
Golden, CO for no cost of analyses. The cost of shipment will be the responsibility of the
consultant. The analyses will be consistent with that described previously.
