1.0 INTRODUCTION
The U.S. Environmental Protection Agency (EPA) retained HydroGeoLogic, Inc. (HGL) to
conduct Remedial Design (RD) activities for the Holcomb Creosote Company (HCC) Superfund
Site (Site), in Yadkinville, North Carolina (Figures 1.1 and 1.2). The Site (EPA identification
number NCD024900987) is located at 5016 U.S. Highway 601 just north of the town of
Yadkinville, in Yadkin County, North Carolina. EPA published a Record of Decision (ROD) for
the Site in August 2018 to address soil and groundwater contamination (EPA, 2018). The selected
groundwater remedy in the ROD includes treating highly contaminated portions of the
groundwater plume using in situ chemical oxidation (ISCO).
An ISCO pilot test was performed between July 2021 (monitoring and injection well installation)
and December 2021 to support the groundwater RD addressing naphthalene and other semivolatile
organic compound (SVOC) contamination in the saprolite and partially weathered rock (PWR)
aquifer zone. The ISCO pilot test was performed in accordance with Addendum to the Final Work
Plan - In Situ Chemical Oxidation Treatability Study and In Situ Enhanced Bioremediation Pilot
Test (Work Plan) submitted to EPA in July 2021 (HGL, 2021a).
This report describes the procedures followed and results obtained during the ISCO pilot test to
(i) evaluate the in situ oxidation of site contaminants of concern (COCs) via the delivery of two
ISCO reagents (modified Fenton’s reagent [MFR] and sodium permanganate) into the subsurface;
and (ii) assess field injection parameters including radius of influence (ROI) and injection pressure
and flow rate for the saprolite and PWR aquifer zones. HGL and team subcontractor Geosyntec
Consultants of NC, P.C. (Geosyntec) have prepared this report under EPA Design and Engineering
Services contract 68HE0318D0006, Task Order 68HE0419F0104.
1.1 SITE OVERVIEW
1.1.1 Site History
Information in this subsection is based on information provided in the ROD (EPA, 2018) and the
Remedial Investigation (RI) Report (Versar, 2017a) and Feasibility Study Report (Versar, 2017b).
A Site facility plan is provided in Figure 1.2.
From 1951 to 2009, HCC operated a wood treating facility on the Site, manufacturing
pressure-treated posts and lumber using creosote coal tar solutions. During facility operations,
wood products were placed into a pressurized treatment vessel and heated with steam to open the
pores of the wood and remove sap and resin. After an allotted time, the vessel was vented to
decrease the interior pressure, and a vacuum was drawn to remove moisture. Following application
of the vacuum, creosote was forced into the pores of the wood. The vapor stream from the
treatment vessel was passed through a condenser, where the water/creosote mixture was liquefied.

U.S. EPA Region 4

After treatment, condensate from the condenser and from depressurization of the treatment vessel
was pumped to a concrete-lined settling tank (i.e., the concrete storage pit). This liquid was
pumped from the concrete storage pit to a steel settling tank, where the solids settled to the bottom.
The liquids were then pumped to an unlined surface impoundment for storage and evaporation.
After treatment, the wood was transported to a drip pad immediately south of the treatment vessel,
where it was allowed to drip dry. In the early 1990s, HCC reportedly ceased using the drip pad;
instead, the wood was allowed to dry inside the treatment vessel and was then moved to a transfer
area located at the end of the treatment vessel. The transfer area measured approximately 25 feet
(ft) by 100 ft and consisted of soil and gravel over a plastic liner and covered by a metal roof. One
55-gallon (gal) sump was located at each end of the treatment vessel to contain any spills that
occurred when the treatment vessel doors were opened. Spilled creosote was pumped back into the
treatment vessel. A catch basin was also located at the end of the treatment vessel where the treated
lumber was removed. The treatment vessel was cleaned from time to time due to buildup of
creosote and solids. This sludge-like waste was removed and placed in 55-gal containers that were
stored in the drum storage area, until they were shipped off Site for disposal.
The surface impoundment, located at the southeastern corner of the facility, reportedly was 30 ft
by 60 ft by 6 ft deep (approximately 80,000-gal capacity) and was used by HCC to store liquid
wastes until 1983. The surface impoundment contained waste classified as EPA hazardous waste
K001 defined as: “bottom sediment sludge from the treatment of wastewaters from wood
preserving processes that use creosote and/or pentachlorophenol.”
Before 1981, HCC constructed a 0.587-acre landfarm on the east side of an unnamed tributary of
North Deep Creek across from the operations area. Residual liquids from the surface impoundment
were pumped to the landfarm, where an irrigation system was used to spray liquids onto the land
surface. The landfarm was utilized when weather conditions did not allow for evaporation in the
surface impoundment and when the surface impoundment was near its storage capacity. From
1982 to 1983, the landfarm was used as a remediation unit for disposal of K001-contaminated
sludge and wastewater removed during closure of the surface impoundment.
HCC ceased wood treating operations on the property in February 2009 and subsequently sold its
assets at auction later that year. In October 2011, the Site was referred to the Comprehensive
Environmental Response, Compensation, and Liability Act program to address known and
potentially hazardous waste contamination. The transfer from former regulation under the
Resource Conservation and Recovery Act (RCRA) program was required because all remediation
activities at HCC had ceased due to lack of funds.
1.1.2 Site Geology
Lithologies identified during previous soil boring and monitoring well (MW) installation at the
Site consist of non-native/remolded fill, alluvium, saprolite, PWR, and metamorphic bedrock.
These lithologic features are discussed below.
• Non-native/remolded fill. Fill material in the form of a thin (approximately 1 to 2 ft thick)
orange-brown silty clay was deposited on the Site following an EPA-lead removal of
contaminated soils during 2011. This surface “cap” covers the Site from Highway 601 to
HGL, ISCO Pilot Test Report, Holcomb Creosote Company Site, Yadkinville, NC
U.S. EPA Region 4
1-3
the west to within approximately 10 ft of an unnamed tributary of North Deep Creek to the
east. A similar clay covers the hilltop near the closed RCRA landfarm to the east of the
unnamed tributary. Additional remolded soils are present near the process buildings, likely
remnants of Site construction and grading.
• Alluvium. Alluvial sediments/soil are present flanking the stream channel of the unnamed
tributary of North Deep Creek. Alluvial materials consist of graded beds of clay, silt,
quartz, lithic and mica sands/gravels, and entrained organic/vegetative matter. The
historical stream channel appears to have been broader than its present course, extending
west toward the facility buildings. Reduction in the stream channel breadth is the result of
backfill with remolded soil. Such fill materials cover the western margin of the unnamed
tributary channel to a depth of approximately 5 ft.
• Saprolite. Saprolitic soil at the Site was derived from in-place chemical weathering of the
native metamorphic bedrock. Site-specific geology descriptions from the RI and Feasibility
Study reports describe the saprolite as a predominantly clay matrix with abundant
vermiculite and other silt to sand-sized micaceous phases and angular quartzite sand lenses.
Soil descriptions from the pre-RD soil borings indicate higher than expected content of silt,
sand, and gravel in the saprolite. Pre-RD saprolite soil samples submitted for geotechnical
laboratory analysis were classified as either silty sand or sandy silt.
• PWR. The saprolite transitions to an underlying weathered gneiss unit, identified in
previous Site reports as PWR. Based on review of previous RI boring logs and soil
descriptions from the pre-RD soil borings, the transition from saprolite to PWR occurs at
a relatively consistent elevation of approximately 835 to 840 ft mean sea level (msl) over
most of the western portion of the Site, generally west of the unnamed tributary that
transects the Site from north to south. The upper portion of the PWR is highly weathered
gneiss that consists of moderately dense, fined to coarse grained silty sand that is gray,
white, and black in color. The PWR becomes increasingly dense with depth until it
transitions to the underlying competent metamorphic bedrock.
• Metamorphic bedrock. Bedrock beneath the Site consists of biotite and amphibolite
gneisses with varying concentrations of purple garnet. Foliation dips from near horizontal
to approximately 20 degrees, with localized foliation discontinuities at small scale folds
and faults. Only a limited number of previous Site borings have been advanced into the
bedrock. Review of the previous boring logs indicates that the top of competent rock is
generally found at elevations of approximately 820 to 825 ft msl.
1.1.3 Site Hydrogeology
Hydrogeologic units at the Site include the surficial aquifer and the gneiss bedrock aquifer. The
surficial aquifer is comprised of the saprolite zone and the PWR zone. The saprolite zone is
composed of the highly weathered portion of surficial aquifer closest to the land surface. The PWR
zone contains weathered bedrock and saprolite and sits immediately above the bedrock. The
surficial aquifer is from 10 to 40 ft thick at the former operations area. Water level measurements
collected during the RI and the pre-RD investigations indicate that groundwater flow direction
within the saprolite zone is generally toward the southeast. The flow direction is slightly more to
the east-southeast in the PWR, and more eastward in the bedrock. The groundwater elevation
contours in the saprolite and PWR from the February 2020 and March 2020 pre-RD investigations

are presented in Figures 1.3A to 1.3D. The vertical groundwater gradient is downward from the
saprolite zone to the PWR zone to the bedrock aquifer in the higher surface elevations of the Site,
which act as a recharge area. The distribution of groundwater contamination from the source area
suggests that the unnamed tributary that transects the Site from north to south is acting as a
discharge area and barrier to contaminant movement.
1.2 CONTAMINANTS OF CONCERN
Based on the groundwater sampling results obtained during the RI and the human health risk
assessment, the COCs presented below were identified for groundwater (based on assumed use as
a residential drinking water source) and for soil (based on protection of the underlying
groundwater). COCs based on direct contact to soil (ingestion, inhalation, and dermal contact)
were not designated because there is no unacceptable risk for direct exposure to the soil for a future
industrial worker. Preliminary remediation goals are provided in parenthesis for the COCs
presented below.
Groundwater
• Cobalt (9 micrograms per liter [µg/L])
• Iron (20,256 µg/L)
• Manganese (694 µg/L)
• 1,1-Biphenyl (400 µg/L)
• 2-Methylnapthalene (30 µg/L)
• Acenaphthene (1,736 µg/L)
• Dibenzofuran (28 µg/L)
• Naphthalene (6 µg/L)
• Benzo(a)pyrene (BaP) toxicity equivalent (TEQ) 0.005 µg/L
• Ethyl benzene (600 µg/L)
Soil
• Naphthalene (180 micrograms per kilogram)
The ISCO pilot test targeted SVOCs in groundwater, specifically 1,1-biphenyl,
2-methylnapthalene, acenaphthene, dibenzofuran, and naphthalene.

2.0 ISCO PILOT TEST OBJECTIVES AND APPROACH
This section presents the ISCO pilot test objectives and a summary of the pilot test approach.
2.1 ISCO PILOT TEST OBJECTIVES
The primary objective of the ISCO pilot test is to assess the effectiveness of the application of
permanganate and MFR to degrade naphthalene and other SVOCs in groundwater, and to assess
injection design parameters for the full-scale design of the selected ISCO remedy in the saprolite
and PWR zones.
The specific objectives of the ISCO pilot test are to:
• Assess the effectiveness of sequential or standalone application of permanganate and MFR
to oxidize naphthalene and other SVOCs (i.e., reduce their concentrations);
o Sequential application of MFR and permanganate was tested in the PWR zone.
o Standalone application of permanganate was tested in the saprolite zone.
• Assess oxidant longevity in both the saprolite and PWR zones;
• Assess the injection parameters such as injection flow rate, injection pressure, and injection
ROI; and
• Evaluate potential changes in geochemistry (e.g., pH and oxidation-reduction potential
[ORP], dissolved oxygen [DO], dissolved metals) from the amendment applications.
2.2 SUMMARY OF ISCO PILOT TEST APPROACH
Details of the ISCO pilot test design are provided in the Work Plan Addendum (HGL, 2021a) and
summarized below.
The ISCO pilot test area was located in the former surface impoundment in the vicinity of MWs
MW-2 and MW-6 in the PWR zone and saprolite zone, respectively.
The PWR zone design included the sequential injection of MFR (a combination of a hydrogen
peroxide solution and a chelated iron catalyst solution) and sodium permanganate into the
subsurface. MFR injections included two rounds of field injections, approximately two weeks
apart. During MFR injections multiple injection fluids were injected including potable water (to
establish flow and push material into the subsurface), diluted hydrogen peroxide, and a chelated
iron catalyst solution. Two weeks following the second round of MFR injection, diluted sodium
permanganate was injected into the subsurface.
Two oxidants were selected for the PWR zone because treatability testing results indicated that
each oxidant was effective at reducing concentrations of specific SVOCs. Permanganate treatment
was generally successful at reducing concentrations of naphthalene, acenaphthene,
2-methynapthalene, and BaP TEQ, but was not effective for 1,1-biphenyl and dibenzofuran
degradation. MFR treatment was the most effective for 1,1-biphenyl and dibenzofuran degradation
but less effective than permanganate treatment in reducing BaP TEQ.

The saprolite zone design included the injection of sodium permanganate into the subsurface
during a single mobilization.
RemOx®-L, which is manufactured by Carus Group, Inc., was chosen as the sodium permanganate
amendment. RemOx-L contains 40 percent (%) by weight sodium permanganate. A 30% by weight
hydrogen peroxide solution was selected for the MFR design.
The target intervals for the pilot test were the 10-ft injection intervals in the saturated saprolite
zone above the PWR zone and saturated PWR zone. Direct-push technology (DPT) was used to
deliver the oxidant into the saprolite zone at one location. Four injection wells were installed to
deliver the oxidants into the PWR zone.

3.0 ISCO PILOT TEST IMPLEMENTATION
This section presents details of the ISCO pilot test implementation, including performance
monitoring and injection well installation, ISCO field injections, and performance monitoring
sampling.
3.1 ISCO PILOT TEST INJECTIONS
This section provides details of the implementation of the ISCO pilot test injections. Field forms
documenting performance MW and injection well installation are provided in Appendix A. Field
forms documenting the ISCO injections (including Daily Field Reports, batching and injection
logs, and other monitoring logs) are provided in Appendix B. A photographic record of the
injections is provided in Appendix C.
3.1.1 Injection Overview and Schedule
ISCO pilot test injections were completed across four separate mobilizations. During these
mobilizations performance monitoring and injection wells were installed, MFR and sodium
permanganate were sequentially injected into the PWR zone, and sodium permanganate was
injected into the saprolite zone. The general timeline for pilot test-related activities and a short
summary is provided below. Details of these events are provided in the following subsections.
• Performance Monitoring and Injection Well Installation: 26 to 30 July 2021
o HGL and subcontractors Geosyntec and Geologic Exploration, Inc. (GEX) installed
two MWs and four permanent injection wells.
• MFR Injections – Mobilization 1: 18 and 19 August 2021
o HGL and subcontractors Geosyntec and Redox Tech, LLC (Redox Tech) injected the
first dose of MFR into the PWR zone using permanent injection wells.
• MFR Injections – Mobilization 2: 2 September 2021
o HGL and subcontractors Geosyntec and Redox Tech injected the second dose of MFR
into the PWR zone using permanent injection wells.
• Sodium Permanganate Injections: 15 to 17 September 2021
o HGL and subcontractors Geosyntec and GEX completed sodium permanganate
injections in the PWR zone and saprolite zone. They injected sodium permanganate
into the PWR zone using permanent injections wells and into the saprolite zone using
a temporary DPT injection point.
3.1.2 Performance Monitoring and Injection Well Installation
HGL and subcontractor GEX installed the ISCO pilot test performance MWs (MW-57 and
MW-58) and the ISCO pilot test injection wells (INJ-1 through INJ-4) from 26 to 30 July 2021
using sonic drilling techniques. The well locations are shown on Figure 3.1.
During well installation, continuous soil cores were collected from each performance MW and
injection well location. The soil cores were logged for color and soil classification, and screened

with a photoionization detector (PID) at regular intervals. Soil boring logs are provided in
Appendix D. Transition from saprolite to PWR was gradual at each boring, and appeared to start
at approximately 19 ft below ground surface (bgs). Elevated PID readings (greater than 20 parts
per million [ppm]) were detected from 22 ft bgs to 26 ft bgs (MW-57) and 18 ft bgs to 27 ft bgs
(MW-58), with maximum PID readings of 78.2 ppm (24 ft bgs at MW-57) and 64.8 ppm (21 ft
bgs at MW-58). Compared to the MW soil cores, injection well soil cores exhibited more elevated
PID readings at shallower intervals; PID readings greater than 100 ppm were measured near
ground surface at injection wells INJ-1 and INJ-2.
The MWs in the PWR zone were constructed of 2-inch Schedule 40 polyvinyl chloride (PVC) with
10 ft, 0.01-inch slotted screens installed from 23 to 33 ft bgs (at MW MW-57, bentonite chips were
placed from 38 ft bgs up to the bottom of the screen at 33 ft bgs). A 20/30 sand filter pack was
placed from the bottom of the screen to 1 ft above the top of screen. Each monitoring and injection
well was constructed with a screen interval located approximately 2 ft below the bottom of the
saprolite aquifer unit to allow for COC monitoring within the PWR layer. Monitoring Well
Construction Forms are provided in Appendix E and the Monitoring Well Development Logs are
provided in Appendix A.
Each MW was constructed with a 3.0-ft bentonite seal above the filter pack, and grout was placed
in the annular space between the borehole and the performance MW casing from the top of the
bentonite seal to ground surface. Each MW was completed with a 2-ft by 2-ft concrete pad and an
above-grade finish. MW casings extend approximately 3 ft above land surface and are protected
with a locking casing.
Each performance MW was developed 2 days following installation using a submersible pump
and new tubing. During development, field parameters were collected, including temperature,
specific conductivity, DO, pH, and turbidity. Approximately 40 gal and 55 gal of groundwater
were purged from wells MW-57 and MW-58, respectively. Turbidity was measured to be 58
nephelometric turbidity units (NTUs) and 21 NTUs upon completion (MW-57 and MW-58,
respectively).
The injection wells were constructed of 2-inch Schedule 40 PVC with 10-ft, 0.01-inch slotted
screens installed from 23 to 33 ft bgs. A 20/30 sand filter pack was placed from the bottom of the
screen to 1 ft above the top of screen, except at INJ-4 (no filter pack was placed above the screen).
Each injection well was constructed with a screen interval located approximately 1 to 2 ft below
the bottom of the saprolite aquifer unit to allow for oxidant injection within the PWR layer.
Injection Well Construction Forms are provided in Appendix E.
Each injection well was constructed with a 3.0 to 7.0-ft bentonite seal above the filter pack, and
grout was placed in the annular space between the borehole and the performance MW casing from
the top of the bentonite seal to ground surface. Each MW was left uncompleted until after the
injections were completed. Following completion of injection, each injection well was completed
with a 2-ft by 2-ft concrete pad and an above-grade finish from 27 to 30 September 2021. Injection
well casings extend approximately 3 ft above land surface and are protected with a locking casing.

3.1.3 Mobilization and Site Setup
HGL and subcontractors Geosyntec and Redox Tech mobilized to the Site on 18 August 2021 to
set up for the MFR injections. Site setup included staging injection and MFR batching equipment
and materials and filling a potable water pillow tank that was staged at the entrance of the site. The
equipment and materials were left on-Site in between MFR injection events.
HGL and subcontractors Geosyntec and GEX mobilized to the Site on 15 September 2021 to set
up for the sodium permanganate injections. Site setup included staging injection and sodium
permanganate batching equipment and materials.
3.1.4 Injection Equipment
Equipment used to inject the MFR solution into injection wells included:
• One 250-gal tote for MFR solution mixing;
• One 4,000-gal pillow tank;
• One diaphragm pump to inject the MFR solution;
o An air compressor was used to operate the diaphragm pump;
• One injection manifold (during the second MFR injection event only), which allowed for
injections to occur at two locations simultaneously, that included the following
components:
o Recordall® Model 25 flow meter to measure the total volume injected;
o Assured Automation WM-PT Series paddle wheel flow meter to measure injection
rates and volumes into one of the two injection locations;
o GPI TM Series flow meter to measure injection rates and volumes into one of the two
injection locations;
o One pressure gauge for each manifold outlet; and
o One ball valve for each manifold outlet flow control;
• Hose, connections, and fittings to connect the injection equipment to the injection wells.
Equipment used to inject the diluted sodium permanganate solution into the injection wells and
DPT tooling included:
• One DPT rig (Geoprobe 7822DT) to advance the temporary injection tooling into the
saprolite zone;
• Two 500-gal sodium permanganate solution mixing tanks;
• One potable water storage tank;
• Diaphragm pumps to transfer RemOx-L to batching tanks and inject the diluted sodium
permanganate solution;
o An air compressor was used to operate the diaphragm pump;
HGL, ISCO Pilot Test Report, Holcomb Creosote Company Site, Yadkinville, NC

• One injection manifold, which allowed for injections to occur at two locations
simultaneously, that included the following components:
o Assured Automation WM-PT Series paddle wheel flow meters to measure injection
rates and volumes into each injection location;
o One pressure gauge for each manifold outlet; and
o One ball valve for each manifold outlet flow control;
• Injection well wellheads with bleed valves;
• 2-ft DPT injection tooling;
• Hose, connections, and fittings to connect the injection equipment to the injection wells
and DPT injection head; and
• Secondary containment for injection material, mixing equipment, and injection equipment.
3.1.5 Injection Solution Batching
The injection solution batching process was similar for the MFR and sodium permanganate
injections. Prior to injection each day, and as needed throughout the day, the injection solutions
were generated by mixing the liquid oxidant with potable water. For MFR injections, sodium
citrate was also added to each batch as a stabilizer. Across the three mobilizations, multiple mixing
ratios were used based on field conditions, and they are summarized below:
• MFR: Diluted hydrogen peroxide solutions were batched at approximately 8.4%, 4.2%,
and 0.5% by weight using a 34% by weight hydrogen peroxide solution and potable water.
o These relied on mixing ratios (34% hydrogen peroxide : potable water) of
approximately 1 : 3.4, 1 : 8, and 1: 68, respectively.
• Sodium permanganate: Diluted sodium permanganate solutions were batched at
approximately 8.6% and 12.6% by weight sodium permanganate.
o These relied on 500-gal batches with mixing ratios (40% sodium permanganate :
potable water) of 83 : 417 and 126 : 374, respectively.
A ferrous sulfate catalyst was also batched as part of the MFR injections. The catalyst was batched
such that 1 pound (lb) of ferrous sulfate was added to 119 gal of potable water.
MFR liquid measurements were made based on visual observations of levels in the 250-gal totes
used for mixing. Scales were used to measure the amount of sodium citrate and ferrous sulfate.
Sodium permanganate liquid measurements were made using in-line flow meters on the diaphragm
pumps used to transfer RemOx-L and potable water to the 500-gal mixing tanks.
Notes documenting that batching process are provided in Appendix B.
3.1.6 Injection Process Summary
During the ISCO pilot study, two amendment delivery methods, permanent injection wells for the
PWR zone and DPT for the saprolite zone, were used,. The general injection process was the same
for both delivery methods. Low-pressure and low-flow injection techniques were used to inject the

U.S. EPA Region 4
3-5
MFR and sodium permanganate solutions into either the four permanent injection wells (INJ-1
through INJ-4) or the temporary DPT injection point (DPT-13). A diaphragm pump or gravity
feeding was used to transfer the MFR or sodium permanganate solutions from the batching area to
the active injection location(s) and into the subsurface. Injection pressures and flow rates were
monitored and adjusted to maintain a sustainable injection rate. During the second MFR
mobilization and sodium permanganate injections, a manifold was used to inject into up to two
locations simultaneously.
During injections, the following measurements were collected (details are provided in the
subsequent section).
• The injection flow rate, injection pressures (at the injection location), and total injection
volumes were recorded at regular intervals.
• Depth-to-water measurements were taken at regular intervals from MWs in and near the
injection area before, during, and immediately following injections each day to evaluate
potential groundwater mounding caused by the injectate. These MWs were MW-2, MW-3,
MW-6, MW-7, MW-57, and/or MW-58.
• Field parameters (pH, temperature, specific conductivity, ORP, and DO) were measured at
MWs in and near the injection area at the beginning and end of each injection day (prior to
injections starting and after injections stopped). Measurements were collected by
deploying a water quality meter directly into each MW. This meter was decontaminated
between wells. Monitoring wells MW-2, MW-3, MW-7, MW-57, and/or MW-58 were
used for monitoring field parameters.
During injection of both MFR and sodium permanganate, daylighting (surfacing of injectate to the
ground surface through a preferential pathway) occurred across the injection area, which resulted
in field adjustments. The field adjustments are reflected in the description of the injection processes
below. Further details of the injections are provided in the subsequent section.
For the PWR zone injections, diluted hydrogen peroxide and sodium permanganate solutions were
injected into each injection well until the target injection volume was achieved or daylighting
occurred. When daylighting occurred, injections were stopped and either restarted at a later time
or moved to another injection well. The overall injection order for the PWR zone injections is
outlined below:
• An 8.4% (by weight) hydrogen peroxide solution was injected into the active injection well
using a diaphragm pump, which resulted in daylighting at most locations.
• A 4.2% (by weight) hydrogen peroxide solution was injected into the active injection well
using a diaphragm pump, which resulted in daylighting at most locations.
• A 0.5% (by weight) hydrogen peroxide solution was injected into active injection wells (up
to two at a time) using gravity feed methods and/or a diaphragm pump, which resulted in
daylighting at most locations.
• An 8.6% (by weight) sodium permanganate solution was injected into active injection wells
(up to two at a time) using gravity feed and/or a diaphragm pump, which resulted in
daylighting at one location (INJ-3).

U.S. EPA Region 4
3-6
The overall injection process for the saprolite zone occurred via DPT as outlined below:
• DPT injection tooling was advanced from land surface to the estimated top of the PWR
aquifer zone (i.e., refusal).
• Injection of a 12.6% (by weight) sodium permanganate solution was completed in four 2-
foot intervals or lifts extending from the top of the PWR aquifer zone to 8 ft above the top
of the PWR zone. Due to daylighting and damage to the injection tool, the planned fifth
injection interval was not completed.
• Injection continued in each injection interval until the target injection volume was reached
or daylighting occurred. Once the target injection volume for that interval had been
emplaced into the subsurface, the injection tooling was raised 2 ft and injection began
again, unless subsurface conditions did not allow the target injection volume to be injected
(discussed in the subsequent section).
• The target injection volume of diluted sodium permanganate solution per interval was
131 gal.
At the end of the saprolite injection, the injection borehole was abandoned using tremie grouting
methods from the bottom up. All injection tooling used at an injection location was decontaminated
with a heated pressure washer prior to leaving the Site.
3.1.7 Injection Implementation Details and Results
Table 3.1 summarizes the oxidant quantities injected during the ISCO pilot test. Due to daylighting
(discussed further below), the injection volumes deviated from the design. Field modifications
were made with the goal of injecting the maximum volume of oxidant possible and injecting the
maximum total volume of injection solutions. During the MFR injections, only one injection well
(INJ-2) was able to receive chase water and catalyst (ferrous sulfate); all other injection wells
received only a diluted hydrogen peroxide solution. During sodium permanganate injections, each
injection well received diluted sodium permanganate; however, only INJ-1 and INJ-2 received the
design volume. In total:
• 81 gal of 34% hydrogen peroxide was injected into the injection wells; and
o Design amount: 248 gal of 30% hydrogen peroxide
• 350 gal of RemOx-L was injected into the subsurface (266.5 gal into injection wells and
88.5 gal into DPT-13).
o Design amount: 525 gal
Daylighting occurred during each injection mobilization and with both injection techniques
(injection wells and DPT). A summary of when and where daylighting occurred, including what
oxidant solution was being injected and how much had been injected before daylighting was
observed, is provided in Table 3.2. Notable observations made during the injection are provided
below.
HGL, ISCO Pilot Test Report, Holcomb Creosote Company Site, Yadkinville, NC
U.S. EPA Region 4
3-7
• During the MFR injection, except injection well INJ-2, all injection wells experienced
daylighting. No discernable difference was observed from the lithology of INJ-02 to the
remaining injection wells that would explain the daylighting.
• Injection of the 8.4% (by weight) hydrogen peroxide solution resulted in strong subsurface
reactions that caused daylighting to occur relatively quickly (less than 40 gal of injection)
at INJ-1, INJ-3, and INJ-4. Furthermore, the injection caused the groundwater table to
increase within the injection area and side-gradient to it near MW MW-3. The depth-to-
water measurements are provided in Table 3.3.
o Routine depth-to-water measurements were halted during the 8.4% (by weight)
hydrogen peroxide injections to avoid removing the compression well caps for health
and safety purposes. Groundwater mounding was measured during all injections, but
to a lesser extent when more dilute hydrogen peroxide solutions or dilute sodium
permanganate solutions were injected.
o There was no notable groundwater mounding measured downgradient of the injection
area at MW MW-7.
• Reducing the concentration of hydrogen peroxide did not decrease the occurrence of
daylighting at injection locations INJ-1, INJ-3, and INJ-4.
• Daylighting from the injection wells decreased during sodium permanganate injections, as
INJ-3 was the only well associated with daylighting of sodium permanganate.
• Daylighting in the saprolite zone was observed at the shallowest injection interval of 17 to
19 ft bgs. Injecting at an offset location was not attempted as the injection tool was
damaged and could not be reused, and no other injection tools were on hand.
The range of injection pressures and flow rates measured during the ISCO injections are
summarized in Table 3.4 (no measurements were collected during the first MFR injection event
because flow meters and pressure gauges were not provided by Redox Tech). Since injections used
diaphragm pumps and gravity feeding to emplace oxidant solutions into the subsurface, a wide
range of injection pressures were measured. Generally, injection flow rates were maintained below
3 gallons per minute (gpm) at both injection wells and DPT injection location DPT-13. Injection
pressures were often measured to be 0 lb per square inch (psi) because gravity feeding was used.
When the diaphragm pump was used for injections, pressures were generally between 20 and
35 psi.
Geochemical parameters were measured directly from MWs within and near the ISCO injection
area using a water quality meter, and the results are presented on Table 3.5. Observations from the
geochemical parameter monitoring are provided below.
• Following MFR injections, elevated DO concentrations were measured within the injection
area at MWs MW-57 and MW-58. Two weeks after the second MFR injection (15
September 2021), DO had decreased at MW-57 but remained elevated at MW-58.
Increases in DO were not measured at MWs downgradient (MW-2 and MW-7) or side-
gradient (MW-3) of the injection area.

• In general, an increase in ORP was measured within the injection area at MWs MW-57
and MW-58 following the first round of MFR injections. A similar increase was also
measured at downgradient MW MW-2.
o The increase of ORP measured at MW-2 suggests that injections had an impact on
groundwater geochemistry immediately downgradient of the injection area, as MW-2
was approximately 8 ft from injection well INJ-4.
o All locations exhibited a large decrease in ORP during the last measurement collected
on 17 September 2021, after the sodium permanganate injections were completed. It is
suspected that the water quality meter malfunctioned based on the previous results and
other geochemical readings collected at that time.
During the injection event, other methods were used to assess the distribution of oxidant in the
subsurface. These methods are discussed below.
• Field test kits for hydrogen peroxide were procured and used during the first MFR injection
event; however, the field test kit was unable to be used accurately, likely due to interference
from compounds naturally present in Site groundwater. During pre-injection testing, the
field kit measured elevated concentrations of hydrogen peroxide (up to 30 milligrams per
liter [mg/L]). The field kit was tested against store-bought purified water and hydrogen
peroxide concentrations were measured to be 0.6 mg/L. Based on these results, the
hydrogen peroxide field test kits were not used.
• Visual observations were used to assess the presence of sodium permanganate, which is
purple. Bailers were placed down well or water color was evaluated during geochemical
parameter measurements. No visual evidence of sodium permanganate was observed
during the injections.
Based on the geochemical parameters measured during injections, it appears as if the target ROI
of 6 ft was achieved with the MFR injections. The lack of visual observation of sodium
permanganate suggests that the actual ROI for this oxidant was less than 6 ft.
3.1.8 Deviations from the Work Plan During Injection
Notable deviations from the Work Plan Addendum (HGL, 2021a) during the ISCO injection pilot
test are described below.
• Baseline samples were analyzed only for iron and manganese due to an error in the
Scribe/chain of custody (CoC). By the time the error was discovered, the samples had been
removed by the laboratory for disposal.
• Mercury was not included in the target analyte list (TAL) metals analyses due to errors in
the Scribe/CoCs. The EPA regional laboratory requires that mercury be explicitly
requested as part of TAL metals analysis (i.e., TAL metals plus mercury). By the time the
error was discovered, the samples were outside the 28-day hold time.
• Prior to drilling, the monitoring and injection well locations were located from Site features
using a measuring tape. The final injection locations (Figure 3.1) recorded by a global
positioning system were slightly different than the proposed locations in the Work Plan
HGL, ISCO Pilot Test Report, Holcomb Creosote Company Site, Yadkinville, NC
U.S. EPA Region 4
3-9
Addendum (HGL, 2021a). The shift resulted in the four injection wells, MW-2, MW-57,
and MW-58 being located approximately 5 to 6 ft north-northwest of the proposed
locations in the Work Plan Addendum. This shift did not result in a significant change to
how existing Site MWs could be used to monitor the ISCO pilot test.
• Due to daylighting, the concentration of hydrogen peroxide was decreased from the design
to reduce the reactivity in the subsurface. This change resulted in less total hydrogen
peroxide being injected into the PWR zone across two mobilizations than designed. In
addition, the iron catalyst for MFR was applied only at INJ-2.
• The total volume of injected RemOx-L was less than the design volume based on site
conditions, field observations, and subsurface responses.
• Due to daylighting, the total oxidant solution volumes injected into the permanent injection
wells and temporary DPT injection point were different than designed. Table 3.1 details
how much diluted oxidant solution was injected into each injection location. For
comparison, Table 3.1 includes the design injection volumes from the Work Plan
Addendum (HGL, 2021a).
• The injection interval for DPT-13 was adjusted from the planned interval of 15 to 25 ft bgs.
No sodium permanganate solution was injected at 23 to 25 ft bgs because flow could not
be established, and from 15 to 17 ft bgs due to daylighting.
3.1.9 Performance Monitoring Sampling
HGL completed ISCO pilot test performance monitoring by collecting groundwater samples from
performance MWs MW-2, MW-6, MW-57, and MW-58 on the dates outlined below. The
sampling schedule relative to the timing of the oxidant injections is provided in parenthesis.
• 28 July 2021 (Baseline; prior to MFR or permanganate injection);
• 14 September 2021 (Week 2: approximately 2 weeks post-MFR injection and before
sodium permanganate injection);
• 13 and 14 October 2021 (Month 1: approximately 1 month post-sodium permanganate
injection); and
• 7 December 2021 (Month 3: approximately 3 months post-sodium permanganate
injection).
Monitoring well sampling was conducted in general accordance with the approved Sampling and
Analysis Plan (SAP) (HGL, 2020) and the groundwater samples were analyzed for performance
monitoring parameters presented in the ISCO pilot test monitoring plan provided in Table 3.6 and
described below.
• SVOCs: Naphthalene and other SVOCs were monitored to evaluate the efficacy of ISCO
in reducing contaminant concentrations.
• Dissolved metals: Dissolved metals were monitored to evaluate potential metals
mobilization following ISCO implementation.
HGL, ISCO Pilot Test Report, Holcomb Creosote Company Site, Yadkinville, NC
U.S. EPA Region 4
3-10
• Permanganate: Permanganate was measured using a field test kit to evaluate distribution
and permanganate consumption rates. Following the permanganate injections, the field test
kits were only used when visual evidence (a purple or pink color in groundwater) was not
observed.
• Hydrogen peroxide: Hydrogen peroxide was measured using a field test kit to evaluate the
concentration of residual hydrogen peroxide in the subsurface. As described in Section
3.1.7, comparison of results for hydrogen peroxide solutions diluted with potable water and
Site groundwater indicated that the Site groundwater contained chemicals that interfered
with the test kit results. For this reason, hydrogen peroxide was not measured in the field
after the first MFR injection.
• Iron: Iron was measured using a field test kit during the baseline sampling and the Week 2
sampling following the MFR injections.
• Field parameters: General field parameters were collected using a calibrated water quality
meter during groundwater sampling to evaluate the geochemical characteristics of the
aquifer following the ISCO injections.
Groundwater samples were collected using low-flow groundwater sampling techniques and
submitted to the EPA Region 4 laboratory under CoC protocol. Field screening was conducted for
select compounds (permanganate, hydrogen peroxide, and iron) using field test kits at the
frequency indicated in Table 3.6.
3.2 INVESTIGATION-DERIVED WASTE
Investigation-derived waste (IDW) generated during the implementation of the ISCO pilot test
included soil cuttings from well installation, MW development/purge water, decontamination
fluids, personal protective equipment, and empty oxidant containers. IDW generated during field
activities (e.g., decontamination water, purge water) was placed in 55-gal drums. For solid IDW,
effort was made to reduce that amount of liquid being placed into the solid IDW drums. IDW was
managed, characterized, and disposed of in accordance with the approved Waste Management
Plan, which was included in the SAP (HGL, 2020). Injection subcontractors (Redox Tech and
GEX) managed the empty oxidant containers.

4.0 BASELINE AND PERFORMANCE MONITORING RESULTS
This section presents the performance monitoring results for the ISCO pilot test, from baseline
monitoring through the Month 3 performance monitoring event (December 2021) at the four
performance MWs (MW-2 [downgradient PWR], MW-6 [downgradient saprolite], MW-57
[within treatment zone], and MW-58 [within treatment zone]). Analytical results are provided on
Table 4.1 (SVOCs) and Table 4.2 (metals). Laboratory analytical reports are provided in Appendix
F.
4.1 FIELD PARAMETERS
Field parameters measured during groundwater sampling are presented on Table 4.1. Select field
parameters collected during the performance monitoring sampling events were used to evaluate
the geochemical characteristics of the aquifers following the ISCO injections. Of particular interest
were DO or ORP, which could be impacted by the injection of MFR (DO, ORP) and sodium
permanganate (ORP). Results for these parameters are summarized below, by MW.
• MW-57 (within treatment zone): DO increased from 0.2 mg/L (baseline) to 17.8 mg/L 2
weeks after MFR injection (September 2021). DO remained elevated 1 month (October
2021) and 3 months (December 2021) after sodium permanganate injections (22.1 mg/L
and 6.7 mg/L respectively). ORP increased from a baseline of 85.1 millivolts (mV) to 153.8
mV 2 weeks after MFR injection. ORP increased further 1 month after sodium
permanganate injections (811.0 mV) and remained elevated 3 months after sodium
permanganate injections (761.1 mV).
o These results indicate that MFR and sodium permanganate injections impacted this
MW.
o DO concentrations measured above saturation in October 2021 indicate that oxygen
generated from hydrogen peroxide injection persisted in the subsurface for at least two
months.
• MW-58 (within treatment zone): DO increased from 0.4 mg/L (baseline) to 17.4 mg/L 2
weeks after MFR injection (September 2021). DO remained elevated 1 month (October
2021) after sodium permanganate injections (7.6 mg/L) and returned to near baseline
conditions 3 months after sodium permanganate injections (December 2021). ORP
increased from negative 147.3 mV (baseline) to 84.4 mV 2 weeks after MFR injection.
ORP continued increasing 1 month and 3 months after sodium permanganate injections
(494.1 mV and 637.8 mV, respectively).
o These results indicate that MFR and sodium permanganate injections impacted this
MW.
o DO concentrations measured above saturation in September 2021, but not October
2021, indicate that oxygen generated from hydrogen peroxide injection persisted in the
subsurface for at least 4 weeks after MFR injections.
• MW-2 (downgradient PWR): DO increased from 1.2 mg/L (baseline) to 4.1 mg/L 2 weeks
after MFR injection (September 2021), then returned to near baseline concentrations
following sodium permanganate injections. ORP fluctuated between baseline (12.2 mV),
HGL, ISCO Pilot Test Report, Holcomb Creosote Company Site, Yadkinville, NC
U.S. EPA Region 4
4-2
2 weeks following MFR injections (56.6 mV), and 1 month following sodium
permanganate injections (3.0 mV). ORP increased by two orders of magnitude 3 months
following sodium permanganate injections (806.3 mV).
o These results indicate that MFR injections and sodium permanganate injections had
some impact on the downgradient area. There was a notable lag in impact following
sodium permanganate injections, as ORP increases were not measured during the
Month 1 monitoring event. This suggests that sodium permanganate migrated into the
vicinity of MW MW-2 area 3 months post-injection.
• MW-6 (downgradient saprolite): DO generally remained low during the performance
monitoring period; the maximum DO measurement was 1.4 mg/L during the Month 2
performance monitoring event. ORP increased from 39.8 mV (baseline) to 545.0 mV
(Month 1) before decreasing back to near baseline conditions (29.0 mV).
o These results indicate that MFR injections in the PWR zone may have had a minor
impact on the downgradient saprolite zone, as DO did not increase but ORP increased
two weeks following MFR injections.
o A continued, and more pronounced ORP increase one month following the sodium
permanganate indicates that sodium permanganate injections in the saprolite zone may
have impacted the downgradient area around MW MW-6.
Based on the field parameter results, MFR and sodium permanganate were distributed within and
downgradient of the treatment zones.
4.2 SVOCs
SVOCs were monitored to evaluate the efficacy of ISCO in reducing contaminant concentrations.
Table 4.1 summarizes the SVOC concentrations. The semivolatile groundwater COCs detected
during the pilot study are acenaphthene, naphthalene, 1,1-biphenyl, 2-methylnaphthalene, and
dibenzofuran. The polynuclear aromatic hydrocarbons (PAHs) that comprise the BaP TEQ were
not detected. Graphs presenting a comparison of acenaphthene, naphthalene, 1,1-biphenyl, 2-
methylnaphthalene, and dibenzofuran concentrations measured at performance MWs over time,
from baseline through Month 3, are provide on Figure 4.1 (MW-57), Figure 4.26 (MW-58), Figure
4.3 (MW-2), and Figure 4.4 (MW-6). In addition, ORP measurements were also depicted in these
figures to present SVOC concentration changes with respect to changes in ORP. A summary of
results, organized by MW, is provided below.
• MW-57 (within the treatment zone):
o The naphthalene concentration decreased from 11,000 µg/L during the baseline event
to 8,800 µg/L at Week 2 (20% decrease) and 5,800 µg/L at Month 1 (47% decrease),
and then rebounded at Month 3 (7,500 µg/L). The lowest detection of 5,800 µg/L
during Month 1 coincided with the maximum ORP measurement.
o The acenaphthene concentration decreased from 690 µg/L during the baseline event to
510 µg/L after the MFR injection (26% decrease) and then continued to decrease to 27
µg/L during Month 3 (96% decrease).
HGL, ISCO Pilot Test Report, Holcomb Creosote Company Site, Yadkinville, NC

4-3
o Similar to naphthalene, the 2-methylnaphthalene concentration decreased between the
baseline event (980 µg/L) and Week 2 (830 µg/L; 15% decrease) and Month 1 (450
µg/L; 54% decrease), and then increased by Month 3 (730 µg/L).
o The dibenzofuran concentration decreased from a baseline concentration of 360 µg/L
to 320 µg/L at Week 2 (11% decrease) and then to 260 µg/L at Month 1 (28% decrease),
then increased slightly to 290 µg/L at Month 3.
o The 1,1-biphenyl concentration fluctuated between 130 µg/L and 140 µg/L between
the baseline and Month 1 events then increased to 180 µg/L in Month 3.
• MW-58 (within the treatment zone):
o The naphthalene concentration decreased from a baseline value of 6,600 µg/L to 5,200
µg/L at Week 2 (21% decrease) and 3,000 µg/L at Month 1 (55% decrease), then
increased to 7,600 µg/L in Month 3. During the Month 3 sampling event, the ORP was
still elevated and sodium permanganate was observed in the purge water.
o The acenaphthene concentration decreased from 450 µg/L during the baseline event to
410 µg/L at Week 2 (9% decrease) and 9.5 µg/L at Month 1 (98% decrease), then
increased to 460 µg/L during Month 3.
o Similar to naphthalene, the 2-methylnaphthalene concentration decreased from a
baseline detection of 730 µg/L to 480 µg/L at Week 2 (34% decrease) and 230 µg/L at
Month 1 (68% decrease). The concentration increased to 1,000 µg/L during Month 3.
o The dibenzofuran concentration decreased slightly (8%) after the baseline event and
then increased from 230 µg/L at Week 2 to 380 µg/L at Month 3.
o The 1,1-biphenyl concentration decreased from 100 µg/L during the baseline event to
80 µg/L at Week 2 (20% decrease) then increased to 140 µg/L by Month 3.
• MW-2 (downgradient of the treatment zone in PWR):
o The naphthalene concentration was stable between the baseline (5,100 µg/L) and Week
2 (5,000 µg/L) sampling events. Following sodium permanganate injection, the
naphthalene concentration decreased to 2,800 µg/L in Month 1 (45% decrease) and
then increased to 3,800 µg/L in Month 3.
o The acenaphthene concentration was 470 µg/L during both the baseline and Week 2
sampling events, then increased to 590 µg/L at Month 1. Between Month 1 and Month
3, the acenaphthene concentration decreased to 520 µg/L.
o The 2-methylnaphthalene concentration decreased slightly from a baseline value of 810
µg/L to 760 µg/L at Week 2 (6% decrease) then increased to 1,000 µg/L at Month 1
and 1,100 µg/L at Month 3.
o Between the baseline event and Week 2, the dibenzofuran concentration decreased
slightly from 260 µg/L to 240 µg/L (8% decrease). Between Week 2 and Month 3, the
dibenzofuran concentration increased to 290 µg/L.
o The 1,1-biphenyl concentration decreased from a baseline detection of 110 µg/L to 84
µg/L at Week 2 (24% decrease), then increased to 120 µg/L at Month 3.

• MW-6 (downgradient of the treatment zone in saprolite):
o The naphthalene concentration decreased slightly from the baseline event (14,000
µg/L) to Week 2 (13,000 µg/L; 7% decrease), and then decreased further to 9,200 µg/L
at Month 1 (34% decrease) following the injection of sodium permanganate. By Month
3, the naphthalene concentration had rebounded to its baseline level (14,000 µg/L). The
maximum ORP of 545 mV for MW-6 was reported during the Month 1 sampling event.
o The acenaphthene concentration increased from 670 µg/L during the baseline event to
710 µg/L at Week 2, then decreased to 130 µg/L during Month 1 (82% decrease from
the Week 2 concentration). Between Month 1 and Month 3, the acenaphthene
concentration increased to 210 µg/L.
o Similar to acenaphthene, the 2-methylnaphthalene concentration increased slightly
between the baseline event (1,000 µg/L) and Week 2 (1,100 µg/L). Between the Week
2 and Month 1 sampling events, the 2-methylnaphthalene concentration decreased to
580 µg/L; 47% decrease). The concentration then increased to 800 µg/L in Month 3.
o The dibenzofuran concentration increased slightly from a baseline value of 350 µg/L
to 370 µg/L during the Week 2 sampling event, then decreased by 41% to a
concentration of 220 µg/L during the Month 1 sampling event. Between Month 1 and
Month 3, the dibenzofuran concentration increased slightly to 240 µg/L.
o The 1,1-biphenyl concentration was 140 µg/L during the baseline event and 150 µg/L
during the Week 2 sampling event. The results for the Month 1 and Month 3 sampling
events were 120 µg/L and 110 µg/L, respectively. The latter result is 21% lower than
the baseline concentration.
It is possible that some of the slight concentration changes noted above were due to natural
variability instead of the pilot study. In addition, the volume of oxidant solution could have diluted
the SVOC concentrations. The Work Plan Addendum for this pilot study (HGL, 2021a) estimated
the total pore volume of the PWR treatment zone to be 7,107 gal. Between the two MFR injection
events, a total volume of 1,064 gal was injected. This injection volume represents 15% of the pore
volume. The total volume of sodium permanganate solution, 1,669 gal, is 24% of the treatment
zone pore volume.
Figure 4.5 compares the percent concentration decreases observed in MW-57 and MW-58 between
the baseline and Week 2 sampling events to the estimated MFR pore volume displacement of 15%.
Percent concentration decreases at or less than 15% may be solely due to dilution; percent
concentration decreases greater than 15% are likely due to a combination of dilution and
degradation. As shown in Figure 4.5, it is likely that the MFR treatment resulted in some
degradation of naphthalene at both wells, acenaphthene at MW-57, and 2-methylnaphthalene and
1,1-biphenyl at MW-58.
Figure 4.6 compares the percent concentration decreases observed at MW-57 and MW-58 between
the Week 2 and Month 1 sampling events to the pore volume displacement of 24% associated with
the sodium permanganate injection. Percent concentration decreases less than 24% might be due
to dilution instead of actual degradation. Percent concentration decreases greater than 24% are
likely due to degradation in addition to dilution. As shown in Figure 4.6, naphthalene,
acenaphthene, and 2-methylnaphthalene concentrations at both wells in the treatment zone

4-5
decreased by more than 24%, indicating that these compounds were degraded in addition to
diluted. The decrease in dibenzofuran concentration at MW-57 could have been solely due to
dilution.
As noted in Section 2.2, the bench-scale study results indicated that sodium permanganate could
effectively degrade the low molecular weight PAHs (naphthalene, 2-methylnaphthalene,
acenaphthene) but was less effective in treating 1,1-biphenyl and dibenzofuran. Conversely, MFR
could effectively degrade the latter two SVOCs but was not effective in treating the low molecular
weight PAHs. The limited degradation of 1,1-biphenyl and dibenzofuran observed during the pilot
study is likely due to the inability to inject the design quantity of hydrogen peroxide. The data
indicate that MFR degraded some of the low molecular weight PAHs. It is not known whether
degradation by MFR occurred through oxidation or aerobic biodegradation from the oxygen
released by the hydrogen peroxide. The sodium permanganate solution degraded the low molecular
weight PAHs. The contaminant rebound that occurred between Month 1 and Month 3 suggests
that sodium permanganate was largely consumed within a month or two after injection.
At downgradient well MW-2, naphthalene was the only SVOC to show a substantial decrease in
concentration. Better treatment was observed at MW-6, where the naphthalene, acenaphthene, 2-
methylnaphthalene, and dibenzofuran concentrations substantially decreased between the baseline
event and Month 1 before rebounding in Month 3. The decrease in dibenzofuran concentration
suggests some downgradient effects of treatment by MFR.
All 1,1-biphenyl and acenaphthene results were less than the cleanup levels, while all naphthalene,
dibenzofuran, and 2-methylnaphthalene results were greater than the cleanup levels. Although the
pilot study decreased concentrations of the latter three compounds, there was not enough
degradation to meet the cleanup levels.
4.3 METALS
Metals may be temporarily mobilized in the aquifer following the ISCO injections due to the
oxidant’s composition and changes in groundwater geochemistry. This section discusses results of
dissolved and total metals analyses. Due to a Scribe/CoC error, baseline monitoring data are
available for only iron and manganese; therefore, changes in other metals can only be evaluated
following MFR injections.
Changes in manganese concentrations can be used qualitatively to assess the presence of sodium
permanganate. At MWs MW-57 and MW-58, manganese concentrations increased by multiple
orders of magnitude between Week 2 and Month 1 performance monitoring events. Concentrations
of dissolved manganese then decreased between the Month 1 and Month 3 performance monitoring
events, indicating that dissolved manganese mostly precipitated at Month 3. The manganese
concentration at downgradient well MW-6 also increased between Week 2 and Month 1, then
decreased between Month 1 and Month 3. At well MW-2, the greatest increase in manganese
concentration occurred between Months 1 and 3, suggesting that sodium permanganate influenced
this downgradient area between 1 month and 3 months post-injection.
Dissolved iron concentrations at each MW were greater than 1,000 µg/L during baseline sampling.
At all MWs, dissolved iron concentrations decreased to non-detectable levels by Month 1 (MW-57,
HGL, ISCO Pilot Test Report, Holcomb Creosote Company Site, Yadkinville, NC
U.S. EPA Region 4
4-6
MW-58, and MW-6) or Month 3 (MW-2). Between Month 1 and Month 3, there was some rebound
towards the baseline concentration measured at MW MW-6.
Many of the metals were not detected in the groundwater samples or did not show appreciable
changes in concentration. The bullets below discuss the metals that exhibited substantial
concentration changes between the Week 2 and Month 3 performance monitoring events.
• Barium: At MW-57, the dissolved barium concentration increased from 61 µg/L during the
Week 2 monitoring event to 510 µg/L during the Month 1 monitoring event, while the
concentration at MW-58 increased from 100 µg/L to 1,300 µg/L. By Month 3, the barium
concentration at both wells had decreased to less than the initial detections. In the
downgradient wells, barium concentrations appeared to have been unaffected by the
permanganate injection.
• Calcium: Calcium concentrations at MW-57 and MW-58 increased by more than an order
of magnitude from less than 10,000 µg/L before sodium permanganate injection to 160,000
µg/L one month after sodium permanganate injection. By Month 3, calcium concentrations
had decreased to 82,000 µg/L at MW-57 and 6,800 µg/L at MW-58. At MW MW-2, the
calcium concentration increased from 6,300 µg/L during Month 1 to 31,000 µg/L during
Month 3 after being stable between Week 2 and Month 1. At MW MW-6, the calcium
concentration appeared to be stable.
• Chromium: Chromium concentrations increased at each MW following sodium
permanganate injection. Concentrations increased from non-detect to greater than 100 µg/L
at MWs MW-57 and MW-58 (160 µg/L and 390 µg/L, respectively) and greater than or
equal to 10 µg/L at MW-2 and MW-6 (10 µg/L and 62 µg/L, respectively). At Month 3,
the dissolved chromium concentration at MW-57 (150 µg/L) remained elevated while the
dissolved chromium concentrations at MW-58 (8.9 µg/L) and MW-6 (46 µg/L) had
decreased. Because the samples were not analyzed for hexavalent chromium, it is not
known how much of the increases in chromium concentrations were due to generation of
hexavalent chromium.
• Lead: Within the treatment zone, the lead concentration increased from non-detectable
levels at MW-57 and MW-58 to 34 µg/L and 78 µg/L, respectively, during the Month 1
monitoring event. This concentration increase was temporary. By Month 3, the lead
concentration had decreased to non-detectable levels at both wells, with reporting limits of
12 µg/L for MW-57 and 16 µg/L for MW-58. Lead was not detected in the filtered samples
from the downgradient wells, suggesting that the temporary increase in lead concentration
within the treatment zone did not migrate downgradient.
• Magnesium: Magnesium concentrations increased by one order of magnitude at MWs
MW-57 and MW-58 following sodium permanganate injections. Concentrations increased
at MW-57 from 1,400 µg/L to 40,000 µg/L and at MW-58 from 2,400 µg/L to 39,000 µg/L.
Concentrations remained elevated through Month 3 at MW MW-57 (23,000 µg/L) but
decreased at MW MW-58 (1,700 µg/L).
• At MW MW-2, the magnesium concentration increased from Month 1 to Month 3 (1,700
µg/L to 9,400 µg/L) after being stable between Week 2 and Month 1. The magnesium
concentration at MW MW-6 did not appear to have been affected by the oxidant injections.

• Nickel: At both MW-57 and MW-58, nickel was not detected in the Week 2 monitoring
event and Month 3 monitoring event samples. During the Month 1 sampling event, the
dissolved nickel concentrations were 34 µg/L in MW-57 and 81 µg/L in MW-58,
suggesting temporary dissolution of this metal. In the downgradient wells, nickel was not
detected until Month 3. At that time, the dissolved nickel concentration was 5.1 µg/L at
MW-2 and 90 µg/L at MW-6. Because the reporting limit for the non-detect results was 40
µg/L, it is not known if the Month 3 detection for MW-2 represented an increase in nickel
concentration. The detection for MW-6 indicates downgradient migration of nickel from
the treatment zone.
• Selenium: Although the detections were not confirmed by the analytical method, the Month
1 selenium results suggest a temporary spike in dissolved selenium concentration within
the treatment zone following the sodium permanganate injection.
• Silver: The dissolved silver concentration within the treatment zone increased from non-
detectable levels during the Week 2 monitoring event to 83 µg/L in MW-57 and 200 µg/L
in MW-58 during the Month 1 monitoring event, then decreased to non-detectable levels
during the Month 3 event. Silver concentrations for MW-2 and MW-6 did not appear to
have been affected by the permanganate injection.
• Thallium: Similar to selenium, the data suggest that the dissolved thallium concentration
within the treatment zone spiked one month after the sodium permanganate injection and
then decreased. Because the detections were not confirmed by the analytical method, there
is uncertainty in these results.
• Sodium: Sodium permanganate injection increased the sodium concentrations at all four
MWs. At MW-2, the change in sodium concentration was not apparent until Month 3. For
all four wells, the Week 2 sodium results ranged from approximately 7,000 µg/L to 8,000
µg/L. At MW MW-57, the sodium concentration increased to 100,000 µg/L during Month
1 and remained elevated through Month 3 (130,000 µg/L). At MW MW-58, the sodium
concentration increased to 380,000 µg/L Month 1 and then decreased to 17,000 µg/L
during Month 3. At MW MW-2, the sodium concentration increased to 19,000 µg/L during
Month 3. At MW MW-6, the sodium concentration increased to 92,000 µg/L during Month
1 and then decreased to 27,000 µg/L during Month 3.
The data indicate that cobalt, which is a groundwater COC, was not affected by the oxidant
injections. In summary, injection of sodium permanganate caused a temporary increase in the
dissolved concentrations of multiple metals.
4.4 PERMANGANATE, HYDROGEN PEROXIDE, AND IRON FIELD TESTS
The results from field tests are provided in Table 4.1. Hydrogen peroxide field tests were not used
during the majority of the performance monitoring due to interference from compounds naturally
present in Site groundwater, as discussed in Section 3.2.8.
Iron field tests were used during only the baseline and Week 2 performance monitoring events per
the Work Plan Addendum (HGL, 2021a). The purpose of this testing was to evaluate the presence
of the iron catalyst associated with MFR. Decreases in iron concentrations were measured at MWs
HGL, ISCO Pilot Test Report, Holcomb Creosote Company Site, Yadkinville, NC
U.S. EPA Region 4
4-8
MW-58, MW-2, and MW-6. The iron concentration increased from 0.9 mg/L to 5.7 mg/L at MW
MW-57.
Permanganate field tests were utilized intermittently during the monitoring period. Following
sodium permanganate injections, visual observations were the primary means of evaluating
whether permanganate was still present in groundwater or whether the oxidant had been consumed.
During the Month 3 performance monitoring event, there was visual evidence of permanganate (a
purple or pink color in groundwater) in MWs MW-57, 58, and MW-2. A measurement was made
at MW-6 during Month 3, and the result was 0.4 mg/L of permanganate. Based on descriptions
provided during Month 1 performance monitoring, permanganate concentrations decreased
between Month 1 and 3 performance monitoring events (color descriptions during Month 3 were
more often described as “light”).

5.0 CONCLUSIONS AND RECOMMENDATIONS
This section provides conclusions and recommendations from the implementation of the ISCO
pilot test completed at the Site. The following subsections are organized in accordance with the
objectives described in Section 2.0.
5.1 INJECTION PROCESS AND PARAMETERS
Based on the ISCO injection execution, sequential injection of MFR and sodium permanganate is
not appropriate at the Site. It was observed that MFR injections were generally prone to daylighting
regardless of injection rate, and intense reactions occurred in the subsurface when the design
dosage was injected, making it difficult or not possible to inject the required oxidant dosing at the
Site. Permanganate was injected with limited daylighting using low-pressure injection techniques.
It appears that low-pressure injection via DPT or injection wells is an appropriate method for
distributing a permanganate solution in the subsurface.
Injection pressures were generally less than 30 psi and injection rates ranged from less than 1 to 3
gpm. Visual observation and geochemical evidence indicated that an ROI of at least 6 ft can be
achieved in the PWR and saprolite zones at the design volume.
5.2 GROUNDWATER CHEMISTRY
Performance monitoring during the two weeks following the injection of MFR and three months
following the injection of sodium permanganate indicated the following regarding the effect of the
oxidants on the groundwater chemistry, primarily changes in DO and ORP:
• DO generally increased within the treatment zone following MFR injections and was
measured at concentrations greater than saturation levels during the Week 2 performance
monitoring event (MW-57 and MW-58) and Month 1 performance monitoring event (MW-
57). DO increased, but to a lesser extent, at the downgradient PWR MW (MW-2) during
the Week 2 performance monitoring event. DO did not increase at the downgradient
saprolite MW (MW-6), which is expected as MFR was not injected directly into the
saprolite zone.
• ORP generally increased from baseline to Month 3 at performance MWs MW-57, MW-
58, and MW-2. At MW MW-6, ORP increased from baseline through Month 1, then
decreased to near baseline conditions during Month 3. At all MW locations, ORP increases
were greatest following sodium permanganate injections.
5.3 CONTAMINANT REDUCTION EFFICACY
Performance monitoring during the three months following the ISCO injections indicated the
following regarding the ability of MFR and sodium permanganate to reduce target SVOC
concentrations:
• Within the treatment area (MW-57 and MW-58), the MFR injection appeared to have
degraded naphthalene at both wells, acenaphthene at MW-57, and 2-methylnaphthalene
and 1,1-biphenyl at MW-58. The sodium permanganate injection degraded low molecular

U.S. EPA Region 4
5-2
weight PAHs (naphthalene, acenaphthene, and 2-methylnaphthalene) at both wells. SVOC
concentrations, however, did not decrease to less than the cleanup values.
• Both downgradient MWs (MW-2 in the PWR and MW-6 in the saprolite) were influenced
by the ISCO injections. At well MW-2, naphthalene was the only SVOC to show a
substantial decrease in concentration. Better treatment was observed at MW-6, where the
naphthalene, acenaphthene, 2-methylnaphthalene, and dibenzofuran concentrations
substantially decreased between the baseline event and Month 1 before rebounding in
Month 3. The decrease in dibenzofuran concentration suggests some downgradient effects
of treatment by MFR.
The limited degradation that occurred after the MFR injection was likely due to the inability to
inject the design quantity of hydrogen peroxide. Sodium permanganate was able to reduce the
concentration of multiple target SVOCs (naphthalene, acenaphthene, and 2-methylnaphthalene),
but was not effective at treating other target SVOCs (1,1-biphenyl and dibenzofuran). Multiple
permanganate injections would likely be required to reduce contaminant concentrations below Site
cleanup target levels, and even then this oxidant might not degrade all of the semivolatile COCs.
Sodium permanganate increased the dissolved concentrations of multiple metals within the
treatment zone, and some of these elevated metal concentrations migrated to the downgradient
wells. The Month 3 data suggest that the increases in metal concentrations are temporary and that
concentrations will return to baseline levels with time.
5.4 RECOMMENDATIONS
Based on the results presented in Section 4 and the conclusions present above, the following
recommendations and observations should be considered in developing a remedial strategy for the
Site.
• MFR does not appear to be a viable oxidation technology for the Site because of the
challenges delivering the design dose of the oxidant,
• Permanganate is a viable oxidant for the Site. During the pilot test, sodium permanganate
was successful at treating naphthalene, acenaphthene, and 2-methylnaphthalene, but not
1,1-biphenyl and dibenzofuran. If ISCO with sodium permanganate injection is selected as
a remedial technology for the Site, it should be paired with another remedial technology,
such as aerobic bioremediation, to treat all of the target SVOCs. HGL evaluated the
effectiveness of the aerobic bioremediation technology with a pilot test in the saprolite zone
(HGL, 2021b).
• Injection activities can achieve an ROI of at least 6 ft, and the Site’s groundwater flow can
aid in the distribution of oxidant to enhance downgradient distribution.
• Multiple rounds of sodium permanganate injection would likely be required to reduce
concentrations of the target SVOCs below their cleanup levels. The injection frequency
should be selected based on field measurement of residual permanganate levels in the
MWs. The rebound in SVOC concentrations observed during the Month 3 monitoring
event indicates that the oxidant dose administered was consumed within 3 months.

• Permanganate injection temporarily increases the dissolved concentrations of multiple
metals. If this technology is implemented full-scale, the performance monitoring program
would need to include TAL metals analysis to track changes in dissolved metals
concentrations.

Field Summary Report for Holcomb Creosote Company
in Yadkinville, North Carolina
Summary of Events for Holcomb Creosote Company MFR injections
Redox Tech was tasked with injecting into 4 wells (INJ-01, INJ-02, INJ-03, and INJ-04) located at the former
Holcomb Creosote Company in Yadkinville, NC. Each well was screened from 33-23 ft bgs and had glued on
2” PVC pipe to NPT thread adapters. This was supposed to be a two-event project separated by roughly 2
weeks.
Redox Tech mobilized to the site on August 18th, and accepted forklift and air compressor rentals, along with
chemicals for the first event. Redox Tech also had a 4,000-gallon pillow tank that was filled up via a large
water tanker for use on the project.
Redox Tech used a 250-gallon IBC tote to mix the chemicals together. Water was first pumped from the pillow
tank to the IBC tote, and then 34% wt hydrogen peroxide was added by using the forklift on site to lift the
hydrogen peroxide tote above the mixing tote then drain the required volume through a 2” cam lock hose that
was fed into the top of the mixing tote, by visually looking at the marks on the front of the tote to indicate the
volume remaining in the hydrogen peroxide tote. The first batch was mixed to the original scope of the project,
for 8.4% solution of hydrogen peroxide. The mix tote held 184 gallons of water, and then 54 gallons of 34 wt%
hydrogen peroxide was added as well as 2 lbs of sodium citrate to create the 8.4% solution. Once mixed, the
solution was then pumped into individual wells using a 2” ARO double diaphragm pump. By adjusting the air

pressure to the pump using a regulator, we were able to control the injection flow rate. An inline pressure gauge
allowed us to determine and regulate injection pressure going into the well.
INJ-02 was the first well to receive the amendment. We first injected ~15 gallons of water and then followed
that immediately with the hydrogen peroxide solution. Injections started off as slowly as possible by keeping
the air pressure regulator on the pump as low as possible yet allowing the pump to operate. From initially slow
flow rates, the air pressure regulator was increased until a flow rate of ~0.9 gallons per minute was achieved,
and at this observed flow rate, the observed injection pressures for this well were relatively high (around 40-45
psi). Injections continued at INJ-02 for just over 2 hours, which received ~113 gallons of solution, before
switching to the next well, INJ-04. INJ-04 took ~40 gallons of solution before amendment surfaced at a point
between all the injection and monitoring wells. Final injection pressure was observed to be 40 psi, and the flow
rate was observed to be ~6.7 gallons per minute. INJ-01 took ~25 gallons of solution before it also surfaced at
the same location that INJ-04 surfaced at. The injection pressure observed at INJ-01 was 20 psi, and the flow
rate observed was ~3.6 gallons per minute. Finally INJ-03 received ~25 gallons of solution as well before it
surfaced around a nearby old monitoring well. The observed injection pressure for INJ-03 was 10 psi, with an
observed flow rate of ~1.6 gallons per minute. After observing injections in all four wells, it became apparent
that only INJ-02 was able to receive a reasonable amount of solution without surfacing. Since we had some
remaining solution left from the first batch of 8.4% wt solution that had been mixed up, the remaining solution
was injected into INJ-02, and then flushed with ~20 gallons of water at the end of the day. Refer to the attached
injection data for more detailed information.
The following day, the original plan was modified to test how the wells would do at half the concentration
(~4.2% wt) of the hydrogen peroxide solution. Injections began with the 4.2% wt hydrogen peroxide and 2 lbs
of sodium citrate into INJ-02 to complete the remaining volume that was initially set out in the scope, 238
gallons of hydrogen peroxide solution. The injection pressure at INJ-02 was observed to be about the same as
the day before, ~40-45 psi, and the observed flow rate was ~0.7 gallons per minute. INJ-02 then received ~10
gallons of flush water, and then followed up with 119 gallons of ferrous sulfate solution. The injection pressure
observed during this solution injection was 40 psi, and the flow rate was noticeably faster, as observed to be
~6.3 gallons per minute.
The rest of the day was spent testing the other three injection wells to see how they would respond to the lower
concentration of hydrogen peroxide. The three injection wells received nearly the same volumes into each well
before they surfaced again in the same locations as the day before. While injecting into INJ-04, it was observed
that the 4.2% wt solution had made its way around the MW-57 casing and filled the stick-up vault with the
bubbly peroxide solution. There was some solution remaining after testing the other 3 wells, and that volume
was injected into INJ-02 to get rid of all mixed peroxide solution. It was observed that this last injection into
INJ-02 was seen to have a faster flow rate of ~4.2 gallons per minute at an observed injection pressure of 10 psi.
This concluded the first injection event at the Holcomb Creosote Company. All rentals were called off rent, all
trash was collected and disposed of off-site, and all equipment was packed up except the pillow tank and one
tote of 34% hydrogen peroxide that had 100 gallons remaining in it, and the crew demobed on August 19th,
2021.
On August 27th, a conference call was held to discuss the next injection event at site, and it was decided to try a
0.5% wt hydrogen peroxide solution into each well and see if injections could be completed. The start of this
event would be to see if gravity feeding into the wells was a viable option, and if not, then switch to a pump.
Using a two-way manifold and injecting into two wells at the same time was also discussed to see if that had
any effect to get more product into the ground.
Redox Tech, Geosyntec, and HGL representatives mobilized back to site on September 2nd to try to get more
information about the site as discussed on the conference call on August 27th. Manifolded injections began in
INJ-01 and INJ-03 by gravity feeding water, and then following that by gravity feeding 0.5% wt hydrogen
peroxide solution. Injections into INJ-03 caused surfacing after ~38 gallons of solution in the same location as
the first event. INJ-01 took ~29 gallons of solution before it stalled. The diaphragm pump was then turned on to
continue injections. INJ-01 received ~42 gallons of solution before it surfaced in the same location as the first
event. Gravity feed injections were then started at INJ-04. After ~35 minutes, INJ-04 received ~29 gallons of
solution, and appeared to have slowed down significantly to a point where the flow rate was less than 0.2
gallons per minute. The pump was turned on to continue injections, and it was noticed that INJ-04 started to fill
up the vault again at MW-57. After injecting into INJ-01, INJ-03, and INJ-04 and realizing that the 0.5% wt
solution had little effect on whether we could get more solution into the ground, it was decided to inject the
remaining volume of 357 gallons as per the original scope of the project, into INJ-02. Injections were completed
with the diaphragm pump. The observed injection pressure was 20 psi, and the average flow rate for the well for
the entire volume was observed as ~2.5 gallons per minute. For more details regarding injections, please refer
to the attached spreadsheet that contains all injection data.
This concluded the second event of injections for the Holcomb Creosote Company site. All remaining chemical
and equipment was packed up and carried back to the Redox Tech’s shop in Cary. All trash was collected and
disposed of offsite. And all rental equipment was fueled up and called off rent. HGL, Geosyntec and Redox
Tech, personnel demobed from site on September 2nd, 2021

Note: Analytes with no known CAS identifiers have been assigned codes beginning with "E", the EPA ID as assigned by
the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigned by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analyte concentration is greater than zero.
MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable
quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.
TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the
estimated concentration reported.

ACRONYMS AND ABBREVIATIONS
CAS Chemical Abstracts Service
Note: Analytes with no known CAS identifiers have been assigned codes beginning with "E", the EPA ID as assigned by
the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigned by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analyte concentration is greater than zero.
MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable
quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.
TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the
estimated concentration reported.

Inorganic Data Review and Validation Report
Site Name: Holcomb Creosote, Yadkinville, NC
Case No.: 49820, Project No.: 22-0051, Work Order Nos.: C215304 (PES), C215305
ELEMENT Sample IDs.: C215304-01-02 (PES), C215305-01-16
Sampling Date(s): 9/14/21-10/13/21
Validated Time of Sample Receipt: 12/1/21
Laboratory Performing Inorganic Analyses: Chemtech Consulting Group, Mountainside, NJ
Date Received from Lab: 12/21/21 (SMO portal)
Analyses conducted: Total Metals and Dissolved Metals (ICP-AES)
The ESAT Work Team has reviewed the above-captioned CLP data package consisting of 18 water samples for total and/or dissolved
metals by ICP-AES analyses according to the contract Statement of Work SFAM01.1 (SOW) and EPA guidelines. This package presents
acceptable contractual and technical performance with qualifications. Additional details are provided below.
The samples were collected between 9/14/21 and 10/13/21 but were not received by the laboratory until 12/1/21.
Examination of laboratory blanks revealed apparent low-level contamination with several metals. Reported detection limits were adjusted
as high as ten times the blank levels to discount possible false positives due to contamination in laboratory blanks.
ICP-AES Analysis
PE Sample Results
The PES recoveries for total metals were scored as within limits by the web-based SPS Web software except for chromium which was
scored warning high in one PES only. All detected chromium results were considered estimated and “J” qualified.
Other QA/QC Results
The sampler did not use separate CLP Nos. as instructed for total and dissolved metals samples so the laboratory was instructed to do so.
Generally, the total metals results were approximately the same results or greater than dissolved metals as expected. However, manganese
was reported as 19,000 ug/L in sample C215305-16 (DBLS6 - dissolved) but 4600 ug/L in sample C215305-15 (DBLR5 - total) for
MW-6_101321 collected 10/13/21 at 15:18. The pH for both samples was measured as <2 by laboratory at the time of digestion. These
reported results were consistent with the raw data submitted.
The laboratory addressed this issue stating that both the samples were analyzed again and “got the same results… [and] suspects the
sampler might have accidentally interchanged total for dissolved and dissolved for total for those two samples as we could see clearly
that the digestate for total metals is lighter in color and the digestate for dissolved is darker.”
A Stage 4 validation consisting of manual review was performed on the inorganic samples submitted for this case.

ACRONYMS AND ABBREVIATIONS
CAS Chemical Abstracts Service
Note: Analytes with no known CAS identifiers have been assigned codes beginning with "E", the EPA ID as assigned by
the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigned by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analyte concentration is greater than zero.
MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable
quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.
TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the
estimated concentration reported.

ACRONYMS AND ABBREVIATIONS
CAS Chemical Abstracts Service
Note: Analytes with no known CAS identifiers have been assigned codes beginning with "E", the EPA ID as assigned by
the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigned by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analyte concentration is greater than zero.
MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable
quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.
TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the
estimated concentration reported.

Report Narrative for Work Order: C215303 Analysis: DMTL
Inorganic Data Review and Validation Report
Site Name: Holcomb Creosote, Yadkinville, NC
Case No.: 49842, Project No.: 22-0052, Work Order Nos.: C215302(PES), C215303
ELEMENT Sample IDs.: C215302-01-02 (PES), C215303-01-08
Sampling Date(s): 12/7/21
Validated Time of Sample Receipt: 12/9/21
Laboratory Performing Inorganic Analyses: Chemtech Consulting Group, Mountainside, NJ
Date Received from Lab: 12/29/21 (SMO portal)
Analyses conducted: Total Metals and Dissolved Metals (ICP-AES)
This report is being re-issued to combine the total metals and dissolved metals data into one report instead of producing two separate
reports.
The ESAT Work Team has reviewed the above-captioned CLP data package consisting of 10 water samples for total and/or dissolved
metals by ICP-AES analyses according to the contract Statement of Work SFAM01.1 (SOW) and EPA guidelines. This package presents
acceptable contractual and technical performance with qualifications. Additonal details are provided below.
Examination of laboratory blanks revealed apparent low-level contamination with several metals. Reported detection limits were adjusted
as high as ten times the blank levels to discount possible false positives due to contamination in laboratory blanks.
ICP-AES Analysis
PE Sample Results
The PES recoveries for total metals were scored as within limits by the web-based SPS Web software except for selenium which was
scored warning low in one PES only. All selenium results were considered estimated and “J” qualified.
Other QA/QC Results
Arsenic was reported as 13 ug/L in the original analysis of sample C215303-07 but as not detected at the CRQL (Contract Required
Quantitation Limit) of 10 ug/L in the duplicate analysis performed. The arsenic result for sample C215303-07 is considered estimated and
“J” qualified.
A Stage 4 validation consisting of manual review was performed on the inorganic samples submitted for this case.

ACRONYMS AND ABBREVIATIONS
CAS Chemical Abstracts Service
Note: Analytes with no known CAS identifiers have been assigned codes beginning with "E", the EPA ID as assigned by
the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigned by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analyte concentration is greater than zero.
MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable
quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.
TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the
estimated concentration reported.

Organic Data Review and Validation Report
Site Name: Holcomb Creosote, Yadkinville, NC
CLP Case No. 49842, Element® Sample Nos. C215303-01, 03, 05, 07, C215301-01 (PES)
Sampling Date(s): 12/7/21
Validated Time of Sample Receipt: 12/9/21
Laboratory Performing Organic Analysis: Chemtech Consulting Group, Mountainside, NJ
Date Received from Lab: 12/29/21 (posted at SMO portal)
Analyses conducted: Semivolatile Extractables
The ESAT Work Team reviewed data for 4 water samples analyzed for Semivolatile Extractables only, per CLP statement
of Work (SOW) SFAM01.1.
The analytical results were reported in one sample delivery group (SDG) by the laboratory. One performance evaluation
sample (PES) for evaluating the laboratory’s performance with using the method was submitted to the laboratory.
A Stage 4 validation consisting of an electronic/manual review (S4VEM) was performed on the organic samples submitted
for this case. The data package presents acceptable technical performance with qualifications.
The laboratory satisfied all contractual and technical holding time limits.
All results associated with erratic initial calibration (ICAL)) performance were flagged “J” with the appropriate Element®
qualifier (CLP16). The percent difference between an initial calibration (ICAL) and a second source verification standard
exceeded 20% for Benzaldehyde. The associated Benzaldehyde results were qualified “J” (QC-3). Deuterated
Monitoring Compounds (DMCs) were used as surrogates in each sample for GC/MS analysis to monitor extraction
efficiency.
Pertinent data quality factors are discussed below.
1.The performance evaluation sample (PES) recoveries for Semivolatile Extractables were scored within limits by
the web-based SPS Web software. Therefore, no data qualification was required based on these criteria.
2.Percent recovery of the DMC 2,4-Dichlorophenol-d3 was less the lower QC limit in sample C215303-07. The
associated results were non-detects and were qualified “UJ” (QS-3).

ACRONYMS AND ABBREVIATIONS
CAS Chemical Abstracts Service
Note: Analytes with no known CAS identifiers have been assigned codes beginning with "E", the EPA ID as assigned by
the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigned by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analyte concentration is greater than zero.
MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable
quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.
TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the
estimated concentration reported.
