Dear Ms. Markey,
Geosyntec Consultants of NC, PC (Geosyntec), on behalf of Wilmington Waterfront Property
Owner, LLC1 (the Prospective Developer [PD]), is submitting this Supplemental Soil Gas Sampling
Report (Report) to the North Carolina Department of Environmental Quality (NCDEQ) Division
of Waste Management (DWM) Brownfields Program for the above -referenced Brownfields
Property (Site).
This Report presents the results from the soil gas screening and sampling completed in October and
November 2021 to support the issuance of a Brownfields Agreement (BFA) for the Site and guide
contaminated vapor and methane mitigation system design.
1. BACKGROUND
The Site and surrounding area operated as the former Almont Shipping terminal from 1870 to
2005. As indicated in the Work Plan for Soil Gas Sampling (Work Plan), a BFA was executed
between the NCBP and Riverfront Holdings II, LLC on 23 June 2008 for the Almont Shipping
Brownfields Property (NCBP No. 10040-06-065; the 19 Harnett Street parce12 and northwestern
'Wilmington Waterfront Property Owner, LLC is the Prospective Developer; the new/current ownership entity is
Wilmington Riverfront Holding Company, LLC.
2 The 19 Harnett Street parcel (originally R04716-001-026-000 in the Brownfields Property Application [BPAI) was
sub -divided into two parcels (R04716-001-026-000 and R04716-001-030-000) to accommodate a zoning requirement.
The Site boundary remains the same as the BPA.

portion of the 41 Harnett Street parcel are included in the Almont Shipping BFA until a new BFA
is executed for the Site). The BFA was amended in 2014 to include an additional land tract owned
by CSX. The Site received eligibility for entry into the NCBP on 18 February 2020 to establish a
new, stand-alone BFA for the two Harnett Street parcels.
The Site is planned to be developed for multi -family apartments, retail space, and an associated
parking garage. The Site redevelopment strategy will incorporate two buildings, defined as
Building 1 and Building 2. Each building is further subdivided into five areas, as follows and
shown on Figure 1.
• Building 1 is the proposed western -most building, and includes subareas Building A,
Building B, and Building C.
• Building 2 is the proposed eastern -most building, and includes subareas defined as
Building D and Building E.
Buildings A, B, C, and D are proposed to include either first floor multi -family use residential or
retail spaces. Building E consists of an open/ventilated parking garage with a small, enclosed
storage and mechanical space.
Geosyntec performed soil and groundwater sampling at the Site in 2020; the results of the sampling
were summarized in a 13 July 2020 NCDEQ Brownfields Site Assessment Report. In May 2021,
NCDEQ subsequently requested that soil gas sampling be performed to evaluate for the potential
for vapor intrusion risk at the Site. The soil gas sampling scope of work was described in the Work
Plan and approved by NCDEQ on 11 May 2021. Eight temporary soil gas probes were installed
and sampled in May 2021 to evaluate potential vapor intrusion exposures at the Site. The results
of this sampling indicated elevated concentrations of volatile organic compounds (VOCs) and
methane. The source of VOCs was not identified; however, the source of methane appeared to be
localized buried debris in the eastern portion of the Site identified during subsequent test pitting
activities. May 2021 soil gas testing results and testing pitting were summarized in an 11 August
2021 Soil and Soil Gas Sampling Report to NCBP.
Removal and off -site disposal of debris and organic material was completed during Site grading
activities that commenced in September 2021 and are still ongoing under the approved
Environmental Management Plan (EMP) for the Site. Removal of debris and organic material was
performed to reduce methane concentrations. Supplemental soil gas sampling was completed in
October 2021 to evaluate methane concentrations following removal work. This scope of work
was described in the Work Plan for Supplemental Soil Gas Sampling (Supplemental Sampling

Work Plan) and Work Plan for Supplemental Soil Gas Sampling - Addendum (Work Plan
Addendum) dated 15 September 2021 and 9 December 2021, respectively. The Supplemental
Sampling Work Plan was approved by NCDEQ on 7 October 2021. The Work Plan Addendum
was submitted retroactively and was verbally acknowledged during a 2 December 2021 conference
call; formal approval is pending.
The remainder of this Report provides information regarding:
• Soil gas screening and sampling (Section 2)
• Additional soil gas screening (Section 3)
• Soil gas screening and analytical results (Section 4)
• Discussion and conclusions (Section 5).
2. SOIL GAS SCREENING AND SAMPLING
On 13 October 2021, Geosyntec and its subcontractor Catlin Engineers and Scientists (Catlin)
installed 10 soil gas probes throughout the Site (SGP-2B to SGP-8B and SGP-9 to SGP-11) as
shown in Figure 1. Probes SGP-213 through SGP-813 were generally co -located with probes SGP-
2 through SGP-8 which were installed and sampled in May 2021 but were abandoned or damaged
during subsequent Site work. Groundwater was encountered at shallower depths than previously
observed. Therefore, the probes were generally installed from 3.5 to 8 feet below ground surface
(ft bgs) as shown in Table 1.
The soil gas probes were constructed using 1/4-inch Nylaflow® tubing connected via a speed -fit
fitting to a six-inch stainless -steel implant. Approximately one foot of sand filter pack was placed
in the borehole to a height of approximately six inches above the probe. Granular bentonite was
then placed in six-inch lifts and hydrated with distilled water to seal the remainder of the borehole
to ground surface. The soil gas probes were fitted with valves at the ground surface to maintain an
air -tight seal. Following installation, soil gas probes were allowed to equilibrate for approximately
48 hours prior to initiating purging and sampling activities.
On 15 October 2021, prior to purging and sampling, a shut-in test was completed to confirm that
the flow controller and Summa® canister fittings in the sampling train did not have evidence of
leaks. Following confirmation of the sampling train integrity, and prior to sampling, a minimum
of 3-liters (L) of soil gas was purged and screened for the presence of VOCs using a
photoionization detector (PID); and pressure, methane, oxygen, and carbon dioxide using a landfill
multi -gas meter. Given the historical presence of methane in Site soil gas, static subsurface
pressure (i.e., subsurface gas pressure relative to atmospheric pressure) was recorded from each
GN7035/202101 Supplemental Soil Gas Sampling Report

soil gas probe prior to purging in general accordance with the NCBP Methane Assessment
Protocol. The static pressure data was collected using a Landfill GEM 5000 (or equivalent multi -
gas meter) and a DG-700 Pressure Gauge manufactured by The Energy Conservatory for
redundancy. Helium was initially used as a tracer gas to complete leak testing during purging to
confirm that each probe was securely sealed and to confirm that ambient air was not present in the
sampling train. However, at SGP-313, SGP-413, SGP-9 to SGP-11, methane was detected in the
field screening samples at concentrations ranging from 18% by volume (% vol) to 65.7% vol. As
noted in the Work Plan, the MGD-2002 helium meter (along with other commonly used helium
meters) indicates in the operator manual that the presence of methane will interfere with the helium
screening results. This could indicate a false positive screening of helium in the sample train, when
the meter is actually detecting methane. Accordingly, helium was not used during the purging and
sampling process if methane was detected in field screening samples. In the cases where methane
was identified in field screening samples, carbon dioxide was also elevated, and oxygen
concentrations were below atmospheric concentrations. These lines of evidence were used to
provide confidence in the integrity of the surface seal, despite not being able to use a helium shroud
at each sampling location.
After purging, seven soil gas samples and one duplicate sample were collected from each location
in pre -evacuated, batch certified 3-L Summa® canisters equipped with 200 milliliter per minute
(ml/min) flow controllers (i.e., 15 minute). Soil gas samples were not obtained from probes SGP-
513, SGP-613, and SGP-813 due to the presence of water identified during purging activities. After
sample collection, the canisters were shipped overnight via FedEx under standard chain -of -custody
protocol to Pace Analytical Services, LLC in Minneapolis, Minnesota (Pace) for VOC analysis by
United States Environmental Protection Agency (USEPA) Method TO-15 and determination of
methane by Method 3C. Following sampling, soil gas probes were left in place for future screening
purposes. Soil gas sampling field forms are provided in Attachment A.
On 18 October 2021, approximately 72-hours following the soil gas purging and analytical
sampling, an additional round of soil gas screening was performed, as follows. Static pressure
measurements were collected from each soil gas probe, and oxygen, carbon dioxide, and methane
were also screened while purging soil gas from the subsurface using the equipment mentioned
previously. Field screening data are summarized on Table 1 and field forms are provided in
Attachment A.
3. SUPPLEMENTAL SOIL GAS SCREENING
On 28 October 2021, Geosyntec and NCDEQ NCBP conducted a conference call to discuss the
preliminary results of the October 2021 soil gas screening and sampling. Due to the elevated
GN7035/202101 Supplemental Soil Gas Sampling Report

concentrations of methane detected during screening, Geosyntec proposed collecting additional
soil gas field screening samples to better understand the lateral extent of the elevated subsurface
methane concentrations. NCDEQ NCBP verbally authorized the installation and screening of
additional soil gas probes as outlined in the 9 December 2021 Work Plan Addendum.
On 2 November 2021, Geosyntec worked with Site General Contractor (GC) Clancy and Theys
Construction Company and subcontractor Regional Probing Services (Regional Probing) to install
19 soil gas probes (B-1 through B-18 and B-2A), shown on Figure 1. Subsequently, 23 additional
soil gas probes (B-19 through B-41) were installed on 15 November 2021 by Geosyntec's
subcontractor Bridger Drilling. The 42 additional soil gas probes were installed in general
accordance with the Supplemental Sampling Work Plan and construction outlined in Section 2,
with the following exceptions:
• Due to the shallow groundwater table and presence of water observed at SGP-513, SGP-
6B, and SGP-8B, soil gas probes B-1 through B-18 were installed approximately 3 ft bgs,
B-2A was installed at 7 ft bgs, and 13-19 through B-41 were installed approximately 2.5 to
3 ft bgs. Although these probes were installed at shallow depths, groundwater was still
encountered during screening activities at multiple locations.
• Borings B-1 through B-3 were advanced with a rotary hammer drill instead of by a direct
push technology (DPT) equipped drill rig.
• B-16 through B-18 and B-2A were constructed using an aquarium air -stone instead of a
six-inch stainless -steel implant.
The soil gas probes were constructed using 1/4 Nylaflow® tubing connected via a speed -fit fitting
to a six-inch stainless -steel implant, except for probes B-16, 13-17, 13-18 and B-2A, as listed above.
Approximately one foot of sand filter pack was placed in the borehole to a height approximately
six inches above the probe. Following installation, soil gas probes were allowed to equilibrate for
at least 2 hours prior to initiating purging and screening activities. No analytical samples were
collected from the probes installed in November 2021. The additional probes were abandoned
during subsequent Site work.
Geosyntec notes that significant additional subgrade debris, including encountered former building
foundations, has subsequently been excavated and removed for off -site disposal since the most
recent (November 2021) soil gas screening. The results of the October and November 2021
analytical testing and field screening are presented in the following sections. It is possible and even
likely that concentrations have decreased following this additional work. Nevertheless, a vapor
intrusion mitigation system (VIMS) is planned below all occupied structures; therefore, no

additional screening or sampling was performed or is planned prior to VIMS installation (discussed
in a separate report).
4. SOIL GAS AND SOIL ANALYTICAL RESULTS
This section summarizes the results of the field screening and laboratory analytical results for soil
gas samples. Soil gas screening results are summarized in Table 1 and analytical results (as
collected during the October 2021 event only) are summarized in Table 2. Laboratory analytical
reports are provided in Attachment B. Soil gas analytical results were compared to the NCDEQ
Soil Gas Screening Levels (SGSLs) for Residential and Non -Residential settings.
4.1 Soil Gas Screening Results
Soil gas field screening results from methane screening events conducted in 2021 are presented in
Table 1 and summarized below:
• Total VOCs (PID Readings)
o Total VOCs were detected by PID at SGP-2B, SGP-4B, SGP-6B, SGP-9, SGP-10,
B-12, and B-19. The highest detection was from SGP-4B with 1.9 parts per million
(ppm) and the lowest detection was from SGP-10 with 0.1 ppm.
• Fixed Gases
o Methane was detected at most locations during at least one screening event, with a
broad range of concentrations, and detected up to 77% vol at B-19. Generally,
methane concentrations are highest on the eastern third and middle third of the Site
(generally co -located with proposed Buildings B, C, D, and E). Methane
concentrations generally decrease toward the west, below proposed Building A.
Methane was not detected at locations SGP-6B and B-30. Methane concentrations
were below 30% vol at locations SGP-2B, SGP-4B through SGP-7B, B-1 through
B-9, B-11 and B-12, B-14 through B-18, B-20 through B-25, and B-28 through B-
33 during the most recent screening events. Methane concentrations in probes
located below proposed Building A (the western -most portion of the Site) were all
below 10% vol in all screening events, which is also below the NCBP residential
threshold of 30% vol. Methane concentrations below proposed Buildings B through
D were above 30% vol in at least one probe.
■ SGP-8B and B-10 were not screened due to the groundwater entrained in
the sampling network. Probes B-34 through B-41 were not screened

because (i) the sampling data set collected near these locations was deemed
sufficient for developing a general understanding of Site conditions for the
purposes of this investigation, and (ii) scheduling constraints with ongoing
site activities precluded access to these locations for field screening.
o Carbon dioxide field screening data is valuable for understanding the general
subsurface conditions and providing confidence that the soil gas sampling probe is
adequately sealed from potential atmospheric air entrainment. Carbon dioxide in
atmospheric air is generally less than 0.1 % vol; which means carbon dioxide levels
detected well above this general threshold provides a line of evidence that
atmospheric air is not interfering with the integrity of the sample. This is especially
important when screening for methane, which will indicate false -positive readings
of helium tracer gas using a helium meter. As a result, other lines of evidence are
important for evaluating the integrity of the surface seal at methane impacted sites,
which can include, in part, an evaluation of carbon dioxide conditions. Carbon
dioxide was detected above 2% by volume in most cases, often over 4-5% by
volume, and up to 35% by vol. The consistently elevated detections of carbon
dioxide above typical atmospheric levels provides confidence in the integrity of the
soil gas screening process.
o Similar to carbon dioxide, oxygen field screening data is valuable for understanding
the general subsurface conditions and providing confidence that the soil gas
sampling probe is adequately sealed from potential atmospheric air entrainment.
Atmospheric oxygen levels are generally around 20-21 % by volume. Oxygen was
detected well below typical ambient air conditions in most samples, except for
locations SGP-613, B-3 and B-17. Decreased subsurface oxygen concentrations are
expected at the Site given the prevalence of methane, as the methane is produced
by methanogenic bacteria under anaerobic conditions (i.e., in the absence of
oxygen). In the three locations where oxygen was comparable to atmospheric
conditions, SGP-613, B-3 and B-17, both methane and carbon dioxide levels are
also low. This may be suggestive of oxygenated shallow soil gas and is not
necessarily indicative of atmospheric air entrainment. Overall, the oxygen field
screening data, when also considered in combination with the methane and carbon
dioxide data, provide confidence in the integrity of the soil gas sampling process
and are generally consistent with what may be expected at sites with subsurface
methane.

o Static pressure (measured in inches of water) was measured at all locations prior to
purging each soil gas probe. The pressure readings from the DG700 and GEM 5000
instruments were typically an order of magnitude different from each other, with
the GEM often recording a static pressure an order of magnitude greater than the
DG700. The DG700 is manufactured by The Energy Conservatory and is a standard
field instrument device that has been used for monitoring pressure in both the
environmental and mechanical industries for many years. Conversely, the GEM
5000 is a comparatively newer piece of equipment that is primarily used as a multi -
gas meter. For these reasons, the DG700 pressure results are recommended to be
relied upon for this scope of work. In general, the DG700 static pressure readings
indicated pressures well below 0.1 inch of water, though a static pressure of 0.49
inches of water was identified at 13-14. Further, static pressure was recorded as 1.2
inches of water at B-17; however, methane was not detected in the sample. Overall,
subsurface static gas pressures are generally negligible, and in only one case above
0.5 inches of water, though methane was not detected in the corresponding sample.
4.1 Soil Gas Sampling Results
Soil gas analytical samples were collected as part of the October 2021 sampling effort; analytical
samples were not collected as part of the November 2021 effort. According to the laboratory
analytical report, the Summa® canisters containing six (SGP-2B, SGP-413, SGP-9, SGP-10, SGP-
11, and SGP-DUP1) of the eight obtained samples were received at the laboratory at zero or
positive pressures. The canisters were under vacuum following sampling as indicated on the
sampling logs. Methane was not detected in any of the pressurized samples, despite corresponding
methane field screening results ranging from 21.0% vol to 65.7% vol for all the pressurized
samples except SGP-213. Due to the difference between field screening data and laboratory results,
the analytical results for these samples likely do not reflect current on -site conditions because of a
possible vacuum loss during transit and/or at the analytical laboratory. The laboratory analytical
report and a case narrative prepared by Pace personnel are included in Attachment B and
Attachment C, respectively.
Despite the challenges with the summa canisters, the soil gas laboratory analytical results were
compared to NCDEQ residential and non-residential SGSLs for completeness and are presented
in Table 2 and summarized below.

• VOCS

Geosyntec Consultants of NC, RC.
o Various VOCs were detected from multiple samples. Benzene and naphthalene
concentrations were reported above the residential SGSLs in one or more samples.
However, no detection was above the non-residential SGSLs.
• Fixed Gases
o The laboratory analytical results are were not consistent with the field screening
results for most of the samples. The only reported methane detection was from the
sample obtained from SGP-3B (46.7% vol), which is relatively consistent with its
field screening result.
The NCDEQ Risk Calculator (June 2021) was used as a screening tool to conservatively evaluate
potential VI risk associated with VOCs in the soil gas (methane is not evaluated using the Risk
Calculator) to residents and non-residential workers assuming: (1) current site conditions; and (2)
that the compounds in soil gas beneath the Site migrate into indoor air. Unacceptable residential
risk was not exceeded based on the supplemental VOC soil gas results. As noted above, this data
may not be reliable based on potential shipping and/or laboratory issues with the canisters.
Attachment D presents the risk screening results as determined by the Risk Calculator.

5. DISCUSSION AND CONCLUSIONS
Ten soil gas probes were installed, and seven locations were screened and/or sampled and
laboratory analyzed in October 2021. During sample collection, elevated methane concentrations
were detected in the field screening results. Subsequently 42 additional probes were installed, and
multiple supplemental screening events were conducted. The results of these events indicate that
a vapor intrusion mitigation system (VIMS) is recommended based upon the NCDEQ Methane
Guidance (NCDEQ, 2020) to mitigate potential vapor intrusion from VOCs and methane at the
Site. A traditional aggregate vent -based VIMS is planned for Building A where subsurface
methane concentrations are below 30% vol. Based on the concentrations of methane above 30%
vol below proposed Buildings B through D, an aerated floor (i.e., CupolexTM) VIMS is planned
below occupied spaces in these areas, as discussed with NCDEQ. A design plan will be
subsequently submitted to NCDEQ for approval prior to installation. We also understand the
results detailed above will be included in Exhibit 2 of the BFA for the Site.

Notes:
1. Data are screened against the North Carolina Department of Environmental Quality (NCDEQ) Sub -slab and Exterior Soil Gas Screening Levels (SGSLs), amended May 2020.
2. Analytical samples were collected on 15 October 2021.
3. Only constituents detected or for which the reporting limit exceed its respective SGSL are included in this table.
4. "U' indicates not detected above reporting limit (RL).
5. "J" indicates an estimated concentration.
6. "C8" indicates that the result may be biased high due to carryover from previously analyzed sample.
5. "-" indicates SGSL not established.
6. µg/m' indicates microgram per cubic meter.
7. If applicable, concentrations exceeding SGSLs are highlighted as shown: Residential SGSL Non -Residential SGSL
8. Chemicals concentrations not detected above the laboratory RL, but where the RL exceeds a residential SGSL, are italicized.
9. Chemical concentrations detected are bolded.
10. "It bgs" indicates feet below ground surface.
11. " indicates that the pressure inside the sample canister was measured by the laboratory at zero or positive pressure upon reciept. Due to the difference between field screening data and laboratory results, the analytical results for
these samples likely do not reflect current sub -surface conditions.

QUALIFIERS
Project: Kettler GN7035
Pace Project No.: 92567959
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TN -The NELAC Institute.
ANALYTE QUALIFIERS

Laboratory Case Narrative

ANALYTICAL SERVICES
Narrative Summary
Pace Charlotte Project # 92567959 Client project ID Kettler GN7035
Pace MN project #10584238
A data review was initiated by Pace Analytical Services Minneapolis air lab at client request due to anomalous results.
The following narrative includes a summary of the steps Pace performs when receiving and handling air samples in
Summa canisters, and a review of the analytical procedures performed for this SDG.
Eight air samples in Summa canisters were received by Pace Analytical Services Minneapolis Air laboratory on October
20, 2021. Analysis requested was EPA TO15 and methane by 3C.
At arrival, the canister vacuums were measured using a NIST certified meter. The vacuum was recorded as "initial
pressure" on the Sample Condition Upon Receipt form. One canister for this project was measured at 0 PSIG, one at -2.5
PSIG and the remaining 6 canisters recorded positive pressures of +5 to +6.5 PSIG. It is unusual for canisters to show an
initial pressure but depending on the type of sample and collection technique used, positive pressures have been noted
in the past.
In the sample receiving process, the initial pressure of the canisters are taken via NIST calibrated gauges and noted on
the SCUR, followed by pressurization if necessary with nitrogen. For samples requiring analysis by Method 3C, the
canister pressures are recorded, but they are not pressurized initially. Instead, they are pressurized by the primary
analyst with Argon gas, so as not to interfere with the analysis of nitrogen. Samples 92567959001 and 92567959002
were received at vacuums of 0 and -2.5 PSIG. These samples were pressurized at analysis of Method 3C by the analyst.
For samples 92567959003 - 008, the initial pressures indicated that they were already at positive pressure, so no
additional pressurization steps were necessary.
The first analysis performed on these samples was Method 3C. For the samples received at a positive pressure, the
analyst made a note that the canisters were already under pressure when they arrived at the instrument from the
receiving group, so no additional pressurization was necessary. Following the Method 3C analysis, the samples were
analyzed by Method TO15. The logbooks notes from the analyst indicate the samples in question were at positive
pressure, which results in a dilution factor of 1x. In normal collection scenarios, a client samples would expect to see a
small dilution as a result of the additional gas (nitrogen or argon) added at the pressurization step.
All the notes indicate that samples 92567959003 - 008 were received under pressure. Additionally, had the lab
accidentally pressurized them, they would have all been pressurized to exact pressures, and these samples varied in
their final pressure.
In closing, all laboratory notes indicate that the sample flow and handling occurred without error and the notes by each
technician and analyst appear to confirm the samples were indeed received under positive pressure.
