1 INTRODUCTION
This report has been prepared as required by NCDEQ UIC Program Injection Permit No.
W10300345, specifically Part IV — Monitoring and Reporting Requirements. The permit was issued
to Trex Properties, LLC (Trex) on July 21, 2017 in response to an Application for Permit to
Construct and/or Use a Well(s) for Injection, for In -Situ Groundwater Remediation dated January
18, 2017. The injection and monitoring work are being conducted by Trex to satisfy environmental
remediation requirements of the NCDEQ Hazardous Waste Section (HWS).
The Trex site consists of two properties that together comprise +/-1.68 acres and accommodate
two warehouse structures each approximately 11,000 square feet in size that were constructed
in the early 1960s. The building at 3114 Cullman Avenue was previously used by Detrex, Inc. to
store various hazardous waste (HW) codes and recycle HW codes F001 & F002 under a
Resource Conservation and Recovery Act (RCRA) Part B permit issued in 1983. Products,
storage containers, and non-RCRA/non-hazardous solid wastes such as used oil were previously
stored at the adjacent building located at 3124 Cullman Avenue. Both properties were acquired
by Trex on June 18, 2013 and are located east of but within the limits of the City of Charlotte. All
of the hazardous and non -hazardous wastes were removed from the two buildings in 2014 and
both are currently unoccupied.
The general locations of the properties and surrounding topography, roads and railways are
shown on the Site Location Map provided as Figure 1. The aerial photograph in Figure 2 shows
the general land use within the immediate vicinity of the properties, local topography, and the
locations of permanent monitoring wells installed as part of the RCRA Facility Investigation. Past
incidental spills of solvents resulted in contamination of unsaturated materials occurring beneath
and adjacent to the two buildings, and underlying groundwater. Solvent contaminated
groundwater has slowly migrated to vacant downgradient properties to the north, and threatens a
perennial stream known as Little Sugar Creek.
The soil and groundwater remediation activities for the site were described in the Conceptual
Approach to Remediation (CAR) prepared by WR and dated July 15, 2016. The NCDEQ HWS
approved these activities in a letter dated October 24, 2016. A soil vapor extraction (SVE) system
consisting of 30 extraction wells was constructed within the two Trex buildings and began
operating in August 2017. The SVE system has operated since that time resulting in significant
reduction of soil contaminant concentrations, and alleviation of vapor intrusion issues at adjacent
properties. Trex provides monthly reports to the NCDEQ HWS to document and track the soil
remediation process. Graphs visibly illustrate the decreasing trends in Photo Ionization Detector
(PID) readings, at some of the vacuum extraction wells having the highest readings in 2017, are
presented in Appendix F.
The approved CAR included injection of iron -activated sodium persulfate at locations on the Trex
properties and adjacent properties to the north. Figure 3 illustrates the UIC Program approved

injection strategy and the approximate locations where nineteen of the twenty proposed injection
wells were installed by Innovative Environmental Technologies, Inc. (IET) on behalf of Trex in
2018. Description of the injection activities are provided in Section 2 of this report, and the results
of post -injection groundwater and surface water monitoring activities are discussed in Section 3.
2 INJECTION OF IRON -ACTIVATED PERSULFATE
IET implemented the oxidant injection strategy described in the UIC application and permit for the
site using the product "Ferric Oxide activated Sodium Persulfate" between January 7th and 17th,
2019 and on behalf of Trex. This product combines a self -activating oxidation persulfate
chemistry while providing components for a longer lasting biological attenuation process following
the initial oxidation event. A copy of the Injection Event Record (IER) dated January 24, 2019 that
IET submitted to the UIC Program is included in Appendix A. A copy of IET's Technology
Discussion and Field Report dated January 2019 is also included in Appendix A, with
photographs to document the event.
Details of the injection event including descriptive logs for each injection point are included in
IET's January 2019 reports. A total of approximately 159,000 pounds of sodium persulfate were
mixed with approximately 14,000 pounds of ferric oxide powder and municipal water to create
about 69,500 gallons of injectant that was introduced into nineteen of the twenty injection wells
referenced previously. Several attempts were made to install injection well IW-16; however,
subsurface obstacles encountered prior to reaching the targeted injection depth prevented
installation of that well. Day -lighting of injectant in the vicinity of wells IW-1 and IW-2 was noted
to the south of the building at 3114 Cullman Avenue. IET consequently utilized direct -push
machinery to inject the prescribed amount of injectant into the subsurface at seven nearby
locations. More detailed descriptions and information regarding the injection event are included
in Appendix A.
3 WATER QUALITY MONITORING
3.1 Monitoring Well Construction
Type II monitoring wells screened in the saprolite include PMW-1A, PMW-2A, PMW-3A, PMW-
4A, PMW-5A, PMW-6A, PMW-7A, PMW-8A, PMW-9A & 9B, PMW-10A, and PMW-11A. Type III
monitoring wells screened in bedrock include PMW-1 B, PMW-2B, PMW-7B, PMW-8B, PMW-9C,
PMW-10B, PMW-11 B, and PMW-13B, Type III monitoring wells have an outer casing that extends
into and is grouted in the top of bedrock to prevent infiltration of water from the saprolite. Table
1 provides construction information for all of the active monitoring wells at the site.
3.2 Groundwater Sampling Procedures
The monitoring plan contained in the UIC application and permit prescribed collection of pre -
injection groundwater and surface water samples that were collected between the dates of

November 26th and 29th, 2018. Groundwater samples were obtained from twenty permanent
monitoring wells, specifically: PMW-1A & 1B, PMW-2A & 2B, PMW-3A, PMW-4A, PMW-5A,
PMW-6A, PMW-7A & 7B, PMW-8A & 8B, PMW-9A, 9B, & 9C, PMW-10A & 10B, PMW-11A &
11 B, and PMW-13B. The sampling locations are shown on Figure 2. Post -injection samples from
these wells were collected approximately one month following the injection event (February 19th
and 20th, 2019), approximately six months following the injection event (July 23rd and 24th, 2019)
and approximately twelve months following the injection event (January 14th and 15th, 2020).
The following procedures were utilized during each of the three sampling events.
Each well's identity and location were confirmed. The depth to the static groundwater level within
the well to be sampled was measured from the reference point on top of the well casing. Field
measurements of volatile organic vapors in the air space at the well head using a calibrated Photo
Ionization Detector (PID) were recorded on the sampling form for the well. The well was then
purged according to the EPA -approved low flow methods using a peristaltic pump equipped with
a variable speed flow controller capable of limiting the purge rate to less than one-half liter per
minute. Field parameters including; water level during purging, volume of water removed,
dissolved oxygen (DO), temperature (degrees 'Celsius), electrical conductivity (or EC in milli -
Siemens per centimeter, mS/cm), pH, oxidation-reduction potential (ORP), and turbidity (NTU)
were monitored during purging and recorded on the sampling forms included in Appendix B. The
post -injection groundwater samples were also field tested for persulfate content using an assay
kit consisting of colorimetric strips, and the test results were also recorded on the sampling forms.
Field parameter measurements were observed to stabilize (less than 10% variance over three
consecutive readings) prior to collecting groundwater samples by decanting directly into
laboratory prepared containers in the order shown below, stored in an ice -chilled cooler, and
transported under standard chain -of -custody protocols to the Pace Analytical Services (Pace)
laboratory located in Huntersville, NC. Each sample was analyzed as follows:
• Volatile Organic Compounds (VOCs) via EPA Test Method 8260D
• Ethene via RSK 175 Method
• Iron via EPA Method 6010D with Preparation Method EPA 3010A
• Chloride and Sulfate by EPA Method 300.0 Rev 2.1 1993
• Total Organic Carbon via Standard Method 531OB-2011
Table 1 also provides depth to groundwater measurements obtained on January 13, 2020 from
the 20 monitoring wells referenced in this section. The depth to groundwater measurements were
used to determine the groundwater elevations shown on Table 1 and in Figure 4. The piezometric
contours depicting equal shallow groundwater elevation shown in Figure 4 indicate that the
direction of groundwater flow is northerly towards Little Sugar Creek. This makes intuitive sense
and is consistent with previous determinations of groundwater flow direction at the site.

3.3 Groundwater Sampling Results
Table 2 provides a summary of the laboratory analytical results for the pre -injection monitoring
event in November 2018, and the three post -injection monitoring events conducted in February,
July 2019 and January 2020. The laboratory analytical reports and chain of custody records for
these events are included in Appendix C. The January 2020 samples contain concentrations of
ten VOCs exceeding their respective North Carolina Groundwater Standards established in Title
15A of the NC Administrative Code Subchapter 2L (21- Standards) at one or more locations. The
VOCs and locations where their concentrations exceed their 2L Standards are shown in the table

The VOCs Tetrachloroethene (PCE), Trichloroethene (TCE) and Cis 1,2 Dichlorothene (Cis 1,2
DCE) were reported above lab detection limits at most monitoring well locations and are
considered the primary contaminants of concern (COCs) at the site. The extent and
concentrations of these three VOCs in groundwater is discussed in the following sections.
3.3.1 Tetrachloroethylene (PCE)
PCE is considered to be a primary COC in groundwater at the site. The January 2020
monitoring event reported PCE concentrations that exceeded its 2L Standard of 0.7 pg/L at
all of the twenty groundwater monitoring locations. The January 2020 PCE concentrations
are shown in Table 2 and are depicted spatially on Figure 5.
The PCE concentrations that exceeded the 2L Standard (0.7 pg/L) ranged from 2.6 pg/L
(PMW-9A) to 29,900 pg/L (PMW-6A). The highest PCE concentrations are present in the
central portion of the site immediately down -gradient from presumed source(s) near
monitoring wells PMW-5A, PMW-6A and PMW-13B, and in the northern portion near the
PMW-9 and PMW-10 well clusters.

Concentration versus time graphs for each VOC detected at a concentration exceeding its
2L standard are included in Appendix D. The graphs of PCE concentration versus time for
shallow groundwater visually illustrate stable or decreasing concentration trends in all
cases. The PCE concentration versus time graphs for deeper groundwater document stable
concentration trends in all cases except that for deep downgradient monitoring wells PMW-
9C and PMW-13B. In the case of 9C, this well is installed within the treatment zone and
downgradient of the treatment area so migration of PCE maybe occurring from the IW-13,
IW-9 area. PMW-13B is screened from 98 to 103 feet below ground surface, approximately
25 feet deeper than the deepest injection well, although within the treatment area. This is
the only monitoring well within the treatment area screened in bedrock. PCE could
potentially be migrating down a compromised grout seal at PMW-13B, or the groundwater
from the highly impacted area around PMW-5A has possibly migrated down vertical
fractures into this deeper well screen.
3.3.2 Trichloroethylene (TCE)
TCE is also considered to be a primary COC in groundwater at the site. The January 2020
monitoring event detected TCE concentrations that exceeded its 2L Standard at all twenty
groundwater monitoring locations. The January 2020 TCE concentrations are shown in
Table 2 and are depicted spatially on Figure 6.
The TCE concentrations that exceeded the 2L Standard of 3 pg/L ranged from 14.3 pg/L
(PMW-2B) to 93,600 pg/L (PMW-5A). The highest TCE concentrations are present in the
central portion of the site near wells PMW-5A and PMW-6, and in the northern portions near
PMW-13B and the PMW-9 and PMW-10 well clusters, similar to the occurrence of PCE.
TCE is a possible degradation product of PCE.
Concentration versus time graphs for each VOC detected at a concentration exceeding its
2L standard are included in Appendix D. The graphs of TCE concentration versus time for
shallow groundwater visually indicate stable or decreasing concentration trends in all cases
except that for PMW-5A, which shows an increasing trend. The TCE concentration versus
time graphs for deeper groundwater also show stable concentration trends in all cases
except that for locations PMW-9C and PMW-13B. In the case of 9C, this well is installed
within the treatment zone and downgradient of the treatment area so migration of TCE
maybe occurring from the IW-13, IW-9 area. PMW-13B is screened from 98 to 103 feet
below ground surface, approximately 25 feet deeper than the deepest injection well,
although within the treatment area. This is the only monitoring well within the treatment area
screened in bedrock. TCE could potentially be migrating down a compromised grout seal
at PMW-13B, or the groundwater from the highly impacted area around PMW-5A has
possibly migrated down vertical fractures into this deeper well screen.

3.3.3 Cis 1,2 Dichloroethene (Cis 1,2 DCE)
PCE and TCE degradation product Cis 1,2 DCE was detected at concentrations that
exceeded its 2L Standard at thirteen of the twenty groundwater monitoring locations. The
January 2020 Cis 1,2 DCE concentrations are shown in Table 2 and are depicted spatially
on Figure 7.
The Cis 1,2 DCE concentrations that exceeded the 2L Standard of 70 pg/L ranged from
94.2 pg/L (PMW-1 B) to 2,610 pg/L (PMW-6A). The highest Cis 1,2 DCE concentrations are
also present in the central portion of the site near wells PMW-5A and PMW-6, and in the
northern portions near PMW-13B and the PMW-9 and PMW-10 well clusters.
The graphs of Cis 1,2 DCE concentration versus time for shallow groundwater reveal the
same stable or decreasing concentration trends in all cases. The Cis 1,2 DCE concentration
versus time graphs for deeper groundwater also show stable concentration trends in all
cases except for deep downgradient locations PMW-9B, PMW-9C and PMW-13B.
Concentration versus time graphs for the all of the VOCs detected in site groundwater by
individual well location are included in Appendix D.
3.4 Surface Water Sampling Procedures
Three surface water samples (SW-1 through SW-3) were collected from Little Sugar Creek (Class
C stream) during the pre and post injection monitoring events at the locations shown in Figure 2.
Each sample was collected by submerging a laboratory -cleaned, non -preserved, one -liter glass
container into the stream and then decanting the water into the laboratory -prepared bottleware
containing the appropriate amount of preservative for the analysis to be conducted.
The samples were stored on ice and transported under standard chain -of -custody protocol to
Pace for analysis of VOCs by EPA Method 8260D. The post -injection surface water samples were
field tested for: persulfate, temperature, pH, electrical conductance, dissolved oxygen, and redox.
The field readings are included on the sampling forms in Appendix B and are summarized in
Table 3.
3.5 Surface Water Analytical Results
PCE concentrations in excess of its North Carolina Surface Water Standard established in Title
15A of the NC Administrative Code Subchapter 2B (213 Standard) of 3.3 pg/L were detected in
the January 2020 surface water samples from locations SW-2 and SW-3 (see Table 3). The
detected PCE concentrations in surface water samples from these locations were 12.1 pg/L (SW-
2) and 8.2 pg/L (SW-3).
TCE concentrations exceeding the 2B Standard of 30 pg/L were also identified in the surface
water samples from location SW-2 (55.4 pg/L) and SW-3 (35.3 pg/L). The concentration of TCE

at upstream surface water location SW-1 (26.4 pg/L) was slightly less than the 2B Standard of 30
pg/L.
Detectable concentration of Cis 1,2 DCE were also identified in all three of the surface water
samples; however, all of the concentrations were below the EPA Tap Water Screening level of 36
pg/L. A 2B Standard for Cis 1,2 DCE has not been established.
The surface water sampling locations and analytical results are also illustrated on Figures 2
through Figure 7. Table 3 summarizes the current and historic surface water analytical results.
Copies of the laboratory analytical reports and chains of custody are included in Appendix C.
4 OBSERVATIONS
A copy of IET's 360-day data evaluation report to Trex is included as Appendix E. IET's report
contains more detailed discussion of the results of the injection in terms of chemical parameter
changes observed in the post -injection analytical results.
Tables 2 and 3 provide comparisons of pre- and post -injection total VOC concentrations at all of
the groundwater and surface water sample locations. The aggregated VOC concentration
comparisons indicate substantial contaminant concentration decreases as a result of the injection
activities documented in this report.
Graphs of total VOC concentrations versus time trends since groundwater monitoring began at
the site in 2012 are included in Appendix D. Overall decreasing VOC concentration trends over
time are apparent at all twenty of the groundwater monitoring locations that are part of the post -
injection monitoring program for the site.
Graphs of pre- and post -injection PCE, TCE and Cis 1,2 DCE concentrations versus time for each
of the surface water samples are included in Appendix D. The graphs of VOC concentrations
versus time for the three surface water samples indicate decreasing or stable concentrations over
the post -injection monitoring period thus far.
Cross -sections showing monitoring and injection wells within the treatment area are provided as
Figures 8 through 10. PCE, PCE and Cis 1,2 DCE concentrations detected in the January 2020
samples are shown by monitoring well location on these cross -sections.
According to IET, chemical oxidation reactions via production of sulfate free radicals appears to
have diminished across the treatment area, overall degradation of total VOCs has been observed;
however, concentrations of primary COCs exceeding target levels remain in most wells.

According to the UIC injection permit requirements, monitoring of injection related byproducts
should continue until their concentrations attenuate to pre -injection conditions or to below the
applicable 2L Standard, whichever is greater.

QET
Executive Summary
On behalf of Trex Properties, Innovative Environmental Technologies, Inc. (IET) has prepared the
following injection report. This report has been prepared to document remediation activities conducted
at the site.
The injection program was implemented from January 7t" to 17t" 2019. The remedial approach
employed the oxidation remediation product "Ferric Oxide activated Persulfate". This product pairs a
self -activating oxidation persulfate chemistry while providing the appropriate components for a longer
lasting biological attenuation process following the initial oxidation event.
The materials introduced across 19 of 20 injection wells included 158,858 pounds of sodium persulfate,
13,826 pounds of ferric oxide powder in approximately 69,536 gallons of solution. Although several
attempts were made IW-16 was not installed due to obstacles encountered prior to reaching the desired
depth. Surfacing of remedial material was encountered during the implementation of the design at
several of the Injection Wells; namely (IW-1, IW-2, IW-3, IW-6, IW-7, IW-10, IW-11 and IW-13).
Ultimately full dosages were applied to IW-3, IW-6 and IW-7 using decreased flow and pressure and
revisiting the location multiple times. IW-1 and IW-2 were not completed in full, but 7 direct push
locations were installed in the area around these two locations in order to distribute the material via
injection. IW-10, IW-11 and IW-13 did not receive a full dosage but IW-12 received the materials left
over from these wells. IW-12 is immediately upgradient of the uninstalled IW-16 location and 10, 11
and 13 were not accepting any more volume without excessive daylighting occurring in and along the
road (Cullman Ave). IW-12 shares a screened interval with IW-13 so the extra material was added there.
The point by point dosages along with instances of surfacing and other field notes are noted in the
attached field logs.
Introduction
The Cullman Ave site located in Charlotte, NC, was identified as having soils and groundwater impacted
by the historical release of chlorinated hydrocarbons. An injection program was conducted by IET for
the remediation of CVOC impacts in both soil and groundwater throughout the designated areas utilizing
advanced oxidation technologies.
Remediation Implementation
Injection Procedures
IET injected a total of injection wells and 7 direct push locations at the Cullman Ave. site. Details
regarding each injection attempt are provided in the field logs in the Appendix.

Direct -Push -Driven Perforated Rod
Placement
A Powerprobe 9500 unit comparable to the one
pictured in Figure 1, was utilized to drive the injection
screen (as seen in Figure 2) to depths ranging from 5
to 27 feet below ground surface (bgs). It is at these
depths, that the likelihood exists of being in close
proximity to the targeted waters in the more
permeable layers that were identified during
FIGURE 1: AMS POWER PROBE 9500 VTR characterization of the site. These more permeable
layers are those believed to have historically
provided the preferential pathways taken by the dissolved -phase CVOCs.
Subsurface Pathway Development
Compressed air was used to propel all injectants
into the subsurface. Compressed air was first
injected into the subsurface at approximately
150 pounds per square inch (psi) until a
significant pressure drop was observed at the
injection pressure vessel. This process is referred
to as pathway development. The intent of this
step is to open pathways in the subsurface for FIGURE 2: RETRACTABLE INJECTION SCREEN
the injectants to follow. These pathways are
believed to be those more permeable pathways along which VOCs are more likely to have
migrated, both in the vadose and saturated zones. Liquid and liquid -entrained injectants are then
delivered with pressurized gas to the pathways that were produced during the development step.
Liquid Injection
A predetermined volume of the sodium persulfate and ferric oxide material was immediately
injected into the subsurface fractures and voids that were developed during the compressed air
injection step.
Liquid Rinse
A small amount of water was injected to clear the injection lines and sand packs of the injectant.
Post Injection Line Purge
Compressed air was injected to clear the lines of all material and to force the remedial components
further into the formation before moving to the next injection location.

Conclusion
The injection program at the Cullman Ave. site was implemented based on the proposed design with
slight field modifications. All proposed injectants were introduced at the targeted depths. It is expected
that the injection event will yield positive results and IET looks forward the assessing the data following
future sampling events.

Photo #1: Innovative Environmental Technologies (IET) injection trailer rig set up in front of 3114
Cullman Avenue. Each of the 20 injection locations is to receive ^3,700 gallons of activated persulfate
solution, in about 17-200 gallon batches. Nine 55 pounds of Klozur persulfate and one 50 pound bag of
ferric oxide are mixed with municipal water to create each 200 gallon batch. Each pallet holds 40 bags
of either persulfate (white bags) or ferric iron (red bags).
Photo #2: Mixing room (left) and injection control room (right). Each empty pallet on left represents
2,200 pounds of persulfate mixed and injected since injection work started on January 7, 2019.

ANALYTE QUALIFIERS
IH This analyte exceeded secondary source verification criteria high for the initial calibration. The reported results should be
considered an estimated value.
IK The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should
be considered an estimated value.
IL This analyte exceeded secondary source verification criteria low for the initial calibration. The reported results should be
considered an estimated value.
J Analyte detected below the reporting limit, therefore result is an estimate. This qualifier is also used for all TICs.
L1 Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated
samples may be biased high.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
M6 Matrix spike and Matrix spike duplicate recovery not evaluated against control limits due to sample dilution.
ML Matrix spike recovery and/or matrix spike duplicate recovery was below laboratory control limits. Result may be biased
low.
v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.

Re: 360-Day Data Evaluation for 3114-3124 Cullman Ave. Site in Charlotte, NC
Dear Mr. Dostal:
Innovative Environmental Technologies, Inc. (IET) is pleased to provide an evaluation of
the groundwater data collected at the Cullman Ave. site in Charlotte, NC. The sampling is
being done to monitor the remedial injections that were completed from 1/7/2019-
1/17/2019. The injection plan included the direct injection of ferric iron activated
persulfate at 20 permanent injection wells. One well (IW-16) was unable to be installed
and three others (IW-1, IW-2 and IW-13) did not accept the proposed amount of reagent.
In these instances field modifications were required in order to apply all the proposed
reagent to the subsurface. In total IET injected 158,858 pounds of sodium persulfate,
13,826 pounds of ferric oxide powder in approximately 69,536 gallons of reagent across
the site.
The figure pictured below identifies the monitoring locations that are installed within the
injection area and over the targeted injection zones. Each of these monitoring locations is
evaluated below.

This monitoring location is located south of the building and is screened at the shallower
depth of 7-12' bgs. Injection wells 1 and 2 were installed in this area but daylighting from
both wells occurred and a change in the application method of the reagent was applied.
DPT locations were installed south of the building in order to apply the remaining reagent
in this area. PMW-lA was sampled during the 30,120 and 360-day monitoring events and
appears to have been impacted by the injection event, increases in sulfate, a drop in pH and
increase in ORP confirm that the injected reagent was successfully applied to this area.
The geochemical and analytical parameters have been included in the table below along
with further discussion on the collected data.

The proliferation of sulfate seen during the 30-day sampling event has since decreased
along with the ORP value in the 360-day sampling event. This is likely a result of mineral
formation of iron sulfates, as the concentration of iron increased during the 120-day event,
but has since decreased to below it's baseline levels during the 360 day sampling event.
pH is beginning to rebound, but remains below 6 which is just out of optimal range for
enhanced attenuation via biological mechanisms. The ORP has remained slightly elevated
at +132mV which is also out of the optimal range for facultative biological attenuation
(typically -100mV to +100 mV). The total HVOC concentrations have decreased by 29%
since the baseline sampling event and 74% since the 120-day rebound. Assuming the
shallower soil's buffering capacity can increase the pH back to it's baseline level of 6.25,
further decreases in these concentrations are expected in the next sampling events at PMW-
lA as sulfate and iron concentrations have remained available.

The proliferation of sulfate in PMW-3A continued through the 120-day sampling event,
but has since decreased to 232,000 ug/L in the 360-day sampling period. The ORP has
remained highly oxidizing at +450 mV, which indicates that the chemical oxidation via
production of sulfate free radicals is continuing to occur. pH remains depressed as a result
of generation/exhaustion of the sulfate free radicals causing temporarily acidic conditions.
The HVOC concentrations have decreased in the 360-day sampling event by approximately
74%, when compared to they're baseline levels. Given PMW-3A's location on the
upgradient edge of the plume and it's screened interval along the deeper zone of the
targeted treatment area, fluctuations in HVOC concentrations seem to correlate with
groundwater level. When groundwater is high, untreated water from under the building
seems to migrate within this well screen, when groundwater is low during the summer
months, concentrations decrease. So long as the well remains highly oxidizing overall
degradation will occur, although at a slower rate than during the 120-day post injection
period. For biological attenuation to occur at an enhanced rate the pH would need to return
to neutral which depends on the bicarbonate alkalinity and buffering capacity of the
groundwater is this area. Noting that baseline pH values were around 5.6 in PMW-3A.

This monitoring location is located northeast of the building and is screened at 30-40' bgs.
Injection wells 4 and 7 were installed and completed as proposed in this area. Daylighting
from IW-7 was observed and thus was completed using a lower injection pressure. PMW-
5A was sampled during the 30, 120 and 360-day monitoring events and appears to have
been impacted by the injection event, increases in sulfate, a drop in pH and increase in
ORP confirm that the injected reagent was successfully applied to this area. The
geochemical and analytical parameters have been included in the table below along with
further discussion on the collected data.

The proliferation of sulfate in PMW-5A occurred during the 30-day sampling event and
has remained elevated during the 360-day sampling event. ORP values have remained
elevated during the 360-day sampling event, sustaining at +366mV. The HVOC
concentrations decreased in the 30-day sampling event, but PCE and TCE have since
rebounded to at or above they're baseline levels. This is likely a result of desorption of the
more hydrophobic compounds having occurred due to the increase in groundwater
temperature from 16.02' in February 2019 to 23.11 ° in July 2019, along with downgradient
migration of more heavily impacted groundwater. The rate of chemical degradation has
slowed in PMW-5A based of concentrations of chloride having remained in the 67,000
mg/L range during the 360-day sampling event. Chloride is the end product of TCE having
been completely oxidized by a sulfate free radical.

Sulfate reduction of HVOCs has not been enhanced as of the 360-day sampling event, due

The proliferation of sulfate in PMW-6A occurred during the 30-day sampling event and
has decreased during the 120 and 360-day sampling events. This is likely a result of the
formation of iron sulfate minerals. ORP values initially increased to +431.3 in PMW-6A
and have remained elevated at +491.0 during the 360-day sampling event. This indicates
that the chemical oxidation via production of sulfate free radicals and hydroxyl radicals is
continuing to occur. pH remains depressed as a result of generation/exhaustion of the
sulfate free radicals causing temporarily acidic conditions. The HVOC concentrations
decreased by approximately 39% in the 360-day sampling event, but concentrations of PCE
and TCE have remained elevated in the 360-day sampling event. This is likely a result of
an initial desorption of the more hydrophobic compounds having occurred due to the
increase in groundwater temperature from 16.23 ° in February 2019 to 23.21 ° in July 2019,
along with an exhaustion of chemical oxidants. An increase in TOC concentrations
indicate that the background SCOD of this area may have been underestimated. PMW-

6A should continue to be monitored as the oxidation event expires ORP values are expected
to decrease and biological attenuation via sulfate reduction expected to occur in the next 6
to 8 months, however pH in this area may need to be adjusted manually if the aquifer's
buffering capacity isn't able to neutralize the pH naturally.

The proliferation of sulfate in PMW-l0A occurred during the 30-day sampling event and
has decreased during the 120 and 360-day sampling events. This is likely a result of the

Sulfate concentrations have depleted to below 100 ppm and iron concentrations have
depleted to 45 ppb. The pH has started to rebound in this monitoring well location,
however it is unlikely that the remaining HVOC concentration will be attenuated via

A slight proliferation of sulfate in PMW-IOB occurred during the 30-day sampling event
and has remained slightly elevated during the 360-day sampling event at 88,600 ug/L. ORP
values initially increased to +243.5 in PMW-lOB and have remained elevated at +224.0
during the 360-day sampling event. The HVOC concentrations decreased by
approximately 43% in the 360-day sampling event, but PCE and TCE have remained
elevated. This is likely a result of the migration of untreated groundwater from upgradient
having impacted PMW-lOB as the depth to water has decreased, noting that IW-16 was
not installed. It is expected that the deeper groundwater at the site will equilibriate and
further reductions of PCE and TCE are expected to occur as the site transitions to a reducing
environment, however complete biological degradation of these compounds is unlikely due
to the lower concentrations of bio-available sulfate and iron in PMW-1 OB.

PMW-11A
This monitoring location is located at the northeastern end of the plume and is screened at
53-63' bgs. Injection wells 14 and 18 were installed and completed as proposed in this
area. PMW-11A was sampled during the 30, 120 and 360-day monitoring events and
appears to have been slightly impacted by the injection event, increases in sulfate, a drop
in pH and increase in ORP confirm that the injected reagent was successfully applied
within or immediately upgradient of this area. The geochemical and analytical parameters
have been included in the table below along with further discussion on the collected data.

A slight proliferation of sulfate in PMW-IOB continues to occur during the 360-day
sampling event. ORP values initially increased to +136mV, and have continued to
increase, having been measured at +447mV during the 360-day sampling event. This
indicates that the injections that occurred upgradient are beginning to impact this area. The
HVOC concentrations decreased by approximately 95% in the 360-day sampling event.
The water entering this location seems to be indicative of the fringe area of injection, likely
from IW-14, and it's possible that injection into IW-18 migrated west rather than towards
this monitoring location. As reducing conditions are enhanced further degradation of the
HVOCs in the area around this monitoring location are expected in the next few sampling
events.

Other On -site monitoring locations
Several other wells have been sampled, but fall either outside of the treatment area or are
screened outside of the injection interval, these include (PMW-4A, PMW-lB, PMW-2A,
PMW-213, PMW-8A, PMW-813, PMW-I IB, PMW-13B, PMW-9A, PMW-913, and PMW-
9C). Generally, these wells were unimpacted by the injection event. Sight increases in
sulfate were noted in PMW-IB, PMW-4A and PMW-9C, and hits of persulfate at PMW-
1113 and PMW-13B. Substantial increases in HVOC concentrations were observed in
PMW-13B and PMW-9C. In the case of 9C, this well is installed within the treatment zone
and downgradient of the treatment area so migration of PCE and TCE maybe occurring
from the IW-13, IW-9 area. PMW-13B is screened from 98-103' bgs, approximately 25'
deeper than the deepest injection well, although within the treatment area. PCE and TCE
could be migrating down a compromised grout seal at PMW-13B, but more likely the
groundwater from the highly impacted area around PMW-5A has migrated down vertical
fractures into this deeper well screen. Geochemical parameters of the groundwater don't
match that of the PMW-5A area but HVOC concentration and chloride/sulfate/iron
concentrations are similar and appear to correlate with the groundwater collected in that
area.
Conclusion and Recommendations
Chemical oxidation via production of sulfate free radicals appears to have run it's course
across the treatment area, overall degradation of total HVOCs has been observed, however
elevated concentrations of HVOCs remain in most wells. Site wide sulfate concentrations
remain elevated and pH levels remain slightly acidic, in order to gain degradation of HVOC
via sulfate reduction a pH buffer is recommended to be applied in these areas, specifically
the PMW-5a and PMW-6a area. In addition, the installation of more injection wells should
be considered, specifically between IW-15 and IW-17, where IW-16 was originally
proposed, another injection well should be considered between IW-13 and IW-17 to catch
some of the migrating HVOC impacted grounwater in that area. Monitoring wells are
recommended to be installed both inside the building and west of PMW-5a to further
delineate the plume both vertically and horizontally, based on this data additional injection
wells may be recommended to be both installed and injected. Deeper injection wells are
likely necessary to address the HVOC concentrations in PMW-13B. If a follow up
injection event is designed an additional oxidation event would also be recommended while
the work within the new injection wells and the pH buffer is being applied.
Please let me know if you have any questions or comments.
