1.0 Introduction

Hart & Hickman, PC (H&H) has prepared this New Technology Cleanup Plan (Cleanup Plan) on
behalf of Siemens Energy, Inc. (SEI) for the former underground storage tank (UST) W-3 release
area located at 5101 Westinghouse Boulevard in Charlotte, Mecklenburg County, North Carolina
(the “Site”). The Site location is shown on Figure 1 and a layout of the Site including the
location of groundwater monitoring wells and former UST W-3 release area is provided on
Figure 2.

The purpose of this Cleanup Plan is to summarize the results of an in-situ groundwater
microcosm pilot study conducted at the Site from July 2022 to October 2022, summarize the
results of pre-remedial soil and groundwater assessment conducted in July 2023, and present the
groundwater remedial technology selected for implementation at the Site. The general format of
this Cleanup Plan was discussed with Mr. Daniel Bowser of the North Carolina Department of
Environmental Quality (DEQ), Division of Waste Management, UST Section in a telephone
conversation conducted on December 14, 2022.

In accordance with the Corrective Action Plan (CAP) submitted in 2009, annual groundwater
sampling from select monitoring wells has been conducted at the Site and annual groundwater
monitoring reports were prepared and submitted to the DEQ from 2009 through 2019.
Additional assessment activities were conducted at the Site from 2018 through 2022 by H&H
and AECOM Technical Services of North Carolina, Inc. (AECOM), on behalf of SEI and
Siemens Real Estate, Inc. (former property owner), respectively. The results of these additional
assessment activities were provided to DEQ in the following H&H documents:

 Summary of Additional Assessment, February 2019;
 Soil Remediation and Recommended Sampling Plan, March 2, 2020;
 Groundwater Sampling Results, July 9, 2020;
 Groundwater Sampling Results, February 26, 2021;
 Groundwater Sampling Results, April 30, 2021;
 ISCO Groundwater Remediation Pilot Study Report, February 9, 2022; and
 Groundwater Sampling Summary Report, April 6, 2022.

Based on the results of the In-Situ Chemical Oxidation (ISCO) pilot study test as implemented
(ISCO Groundwater Remediation Pilot Study Report, February 9, 2022), H&H concluded that
this remedial approach would not achieve reductions in concentrations of chlorinated volatile
organic compounds (CVOCs) to levels below UST Section, Gross Contamination Levels
(GCLs). The CVOCs of concern at the Site include tetrachloroethene (PCE) detected in
groundwater samples collected from monitoring wells MW-3-S and MW-31-S (and
intermittently in MW-1-S and MW-35-I) and vinyl chloride detected groundwater samples
collected from monitoring well MW-3-S. Historical PCE concentrations detected in these four
wells from 2002 to 2022 are presented on the graphs contained in Appendix A and summarized
in Table 1.

H&H subsequently recommended evaluating alternative remedial technologies to reduce
contaminants of concern in groundwater to concentrations below GCLs (Groundwater Sampling
Summary Report, April 6, 2022). As a result, H&H conducted additional groundwater sampling
activities at the site in March 2022 for the purpose of evaluating potential In-Situ Chemical
Reduction (ISCR) technologies. These activities included collecting groundwater samples from
monitoring wells MW-1-S, MW-3-S, MW-31-S, and MW-35-I for analysis of VOCs, total
organic carbon, total iron, ferrous iron, total manganese, alkalinity, volatile fatty acids, methane,
ethane, ethene, sulfate, nitrite, nitrate, and chloride. In addition, groundwater samples were
collected from these four monitoring wells for analysis of microorganisms and functional genes
capable of bioremediating the CVOCs of concern at the site using Microbial Insights (MI)
Census® and QuantArray® analyses. Based on the results of the groundwater sampling event
conducted in March 2022, H&H recommended conducting an in-situ microcosm pilot study to

further evaluate the potential for groundwater remediation via ISCR. Results of the microcosm
pilot study are summarized in Section 2.0.

2.0 In-Situ Microcosm Pilot Study

H&H conducted the in-situ microcosm pilot study test from July 11, 2022 to October 12, 2022
(91 days). The pilot study consisted of emplacing Bio-Trap® Advanced Diagnostic Samplers
provided by MI into monitoring wells MW-3-S and MW-31-S. Each Bio-Trap® assembly
consisted of a monitored natural attenuation (MNA) unit, a bio-stimulation (BioStim) unit, and a
bio-augmentation (BioAug) unit. Each BioStim unit was amended with Terra Systems’ SRS®-
SD EVO, a small droplet emulsified vegetable oil with a nonionic emulsifier. The BioAug unit
placed in monitoring well MW-3-S contained a TSI DC® Dehalococcoides mccarti (DHC)
culture amended with SRS®-SD EVO. The BioAug unit in monitoring well MW-31-S contained
a DHC culture amended with SRS®-EZVI, a combination of soybean oil, surfactant, water, and
fine microscale Zero Valent Iron (ZVI). The results of the in-situ microcosm pilot study test are
presented in the report prepared by MI dated October 28, 2022 and contained in Appendix B.

In summary, the results of the in-situ microcosm pilot study test indicated that the potential for
complete reductive dichlorination of the CVOCs of concern at the Site was moderate in each unit
emplaced in both MW-3-S and MW-31-S. The analysis of both the BioStim and BioAug units
emplaced in each monitoring well reported increased concentrations (when compared to the
MNA unit) of degradation products indicative of reductive dichlorination. These degradation
products included: cis-1,2-dichlorothene, trans-1,2-dichloroethene, vinyl chloride, methane,
ethane, and ethene. In addition, both BioAug units indicated appreciable enhancement of the
genetic potential for complete reductive dichlorination of the CVOCs by the increased presence
of dechlorinating bacterial genera and functional genes.

3.0 Remedial Design Characterization

Following completion of the in-situ microcosm pilot study test, H&H contracted the services of
AST Environmental, Inc. (AST), an injection contractor, to review the site data. After AST’s
review, H&H and AST conducted a meeting at the site on February 15, 2023 to visually inspect
the area of concern and associated infrastructure (i.e., monitoring well locations, former UST
W-3 location, building structures, utilities, etc.). Based on AST’s review of the site data and
physical layout, additional subsurface characterization of the former UST W-3 release area was
recommended.

From July 10 through July 14, 2023, AST conducted remedial design characterization sampling
activities at the SEI site. Assessment consisted of the advancement of 19 soil borings using
direct push, dual tube tooling technology and the installation of nine temporary monitoring wells
in five bore holes. A total of 255 saturated and unsaturated soil samples and 12 groundwater
samples were collected during the assessment and submitted to the Remediation Products, Inc.
(RPI) Project Support Laboratory for analysis of CVOCs according to EPA SW-846 Method
8260B. In addition, the groundwater samples were submitted to the laboratory for analysis of
multiple anions according to EPA Method 300.1 and dissolved gases according the Method RSK
175 for evaluation of aquifer geochemicals that affect remedy implementation and CVOC
degradation.

Based on the results of the additional assessment, no significant saturated or unsaturated soil was
identified in the investigation area which would likely leach to groundwater in concentrations
above GCLs. CVOC impact in groundwater was further defined and indicated only an area
south of the former UST W-3 area that exhibited concentrations of PCE and vinyl chloride above
GCLs. A copy of AST’s Quantitative High Resolution Site Characterization Report is provided
in Appendix C. Investigation-derived waste (IDW) generated during the assessment was
sampled and containerized in secured, 55-gallon steel drums and disposed by SEI. The
laboratory analytical results of the IDW samples are provided in Appendix D.

4.0 Selected Remedial Approach

AST is an approved injection contractor of products manufactured by RPI. RPI’s products
include BOS 100® and CAT 100® which are products used to treat soil and groundwater
impacted by CVOCs. Both products are approved as injectants by DEQ.

BOS 100® consists of activated carbon that has been impregnated with metallic iron. The
manufacturing process results in an extremely large (metallic iron) surface area that is highly
active. Typically, the product is mixed with water and the resulting slurry is then injected using
high pressure pumps. Since the product is granular, in clay/silt formations its installation results
in seams of material that form preferential pathways throughout the formation. This enhances
contact and provides a long-term mechanism for “effective contact” and this mechanism remains
active for an indefinite period. In sands or sandy soils, uniform distributions are possible.
Contaminants are “trapped” by the activated carbon and then degraded by reaction with the
metallic iron.1

CAT 100® is a fusion of RPI’s BOS 100® and biotechnology to produce a technology capable of
achieving results beyond the capabilities of either one alone. Electron transfer is promoted as the
contaminant binds to the metal creating an electrical connection extending throughout the
carbon. An electron pump created by slow degradation of complex carbohydrates and peptides
feeds electrons to the conductor which shuttles them to the site of depletion. In this process the
metallic iron facilitates catalytic degradation of the contaminant without significant depletion of
the iron. This overall cycle enables degradation of far more contaminant mass than would be
estimated by simple iron demand.2

4.1 Notice of Intent
The proposed injection area encompasses approximately 3,000 square feet (ft2). Because the
proposed injection area is less than 10,000 ft2, the proposed injection activities are “permitted by

rule” and do not require an individual permit. H&H will prepare and submit a Notice of Intent
(NOI) to Construct or Operate Injection Wells to the NCDEQ, Division of Water Resources in
accordance with 15A NCAC 02C .0225.

4.2 Remedial Product Application
Prior to initiating the injection activities, SEI will clear the areas targeted for remediation of
surface obstacles including staged parts and equipment, container pods, and other stored
materials/items. H&H will subsequently locate the proposed injection points and contract with a
private utility locator to screen the locations for subgrade utilities using geophysical methods. In
addition to the private utility locator, the injection locations will be hand cleared to
approximately five ft bgs prior to the use of mechanical injection equipment to further screen the
locations for the presence of subsurface utilities.

A direct-push drill rig and injection rods will be used to emplace the substrate into the
subsurface. Injection is proposed to be conducted from depths of approximately 31 to 17 ft bgs
in 44 points. The 12 injection points advanced in the northern section of the remediation area
(purple shading on Figure 3) will be spaced approximately 10 ft apart, and the 32 injection
points advanced in the southern section of the remediation area (yellow shading on Figure 3) will
be spaced approximately 7.5 ft apart. Approximately 90 vertical intervals will be injected in the
12 northern points (seven to eight intervals in each boring) and approximately 320 vertical
intervals will be injected in the 32 southern points (10 intervals in each boring). Approximately
3,600 pounds of the BOS 100®/CAT 100® mix will be injected in the northern section, and
approximately 8,000 pounds of the BOS 100®/CAT 100® mix will be injected in the southern
section. Additional details of the proposed substrate loading are presented on the injection
design basis sheet in Attachment F.

5.0 Groundwater Monitoring

To monitor the performance of the injection event, H&H will collect groundwater samples from
select monitoring wells at the following intervals: 1) after approximately two weeks following
the injection, 2) after approximately one month following the injection, and 3) quarterly
thereafter for one year (total of six events). The groundwater samples will be collected using
new disposable bailers or a subsurface pump with new tubing. Groundwater samples will be
collected from the following 10 monitoring wells: MW-1-S, MW-3-S, MW-9-S, MW-9-I, MW-
30-S, MW-31-S, MW-31-I, MW-35-I, MW-47-S, and MW-49-S. Groundwater samples
collected during each performance monitoring event will be submitted to a North Carolina
certified laboratory for analysis of volatile organic compounds (VOCs) according to EPA SW-
846 Method 8260. In addition, during three of the performance sampling events, groundwater
samples will be collected for analysis of methane, ethene, and ethane (MEE) according to
Method RSK-175 and carbon dioxide according to Standard Method 2320. H&H will also
collect field measurements of pH, electrical conductivity, temperature, dissolved oxygen, and
oxidation-reduction potential at the time the groundwater samples are collected.

Following the completion of the six performance monitoring events, H&H will prepare a
summary report for submittal to NCDEQ. The report will include tabulated laboratory analytical
results, updated groundwater contaminant plume maps, and our conclusions and
recommendations.

Executive Summary

QuantArray®-Chlor analysis was performed on samples collected from In Situ Microcosm (ISM) Bio-Traps® deployed for 91
days in monitoring wells MW-3-S, and MW-31-S. The purpose of this ISM study was to assess the potential for enhanced
anaerobic reductive dechlorination of chlorinated solvents under electron donor amendments. The ISM assemblies deployed
in both wells consisted of three Bio-Trap units: (i) a control monitored natural attenuation (MNA) unit with no exogenous
amendment, (ii) a BioStim unit amended with SRS-SD as the electron donor, and (iii) a BioAug unit with TSI DC microbial
culture, which was amended with SRS-SD in MW-3-S and SRS-EZVI in MW-31-S. Concentrations of chlorinated
contaminants, dissolved gases, volatile fatty acids (VFAs), and anions are provided in Tables 1 - 2. Results of QuantArray®-
Chlor analysis for the samples are summarized in Tables 3 – 12 and Figures 1 – 14. Background information on the spectrum
of potential biodegradative processes indicated by QuantArray®-Chlor analysis is provided at the end of this report as a
guide to the interpretation of the taxonomic and functional gene data. Key observations for each sample are described in
detail below.
MW-3-S MNA, BioStim, and BioAug Units
• Overall, QuantArray®-Chlor results indicated that the potential for the complete reductive dechlorination of
chlorinated ethenes (PCE, TCE, cis-DCE, vinyl chloride) was moderate under all ISM conditions. However, both
biostimulation with SRS-SD and bioaugmentation with the TSI DC culture and SRS-SD amendment appreciably
enhanced the genetic potential for complete reductive dechlorination of chlorinated ethenes compared to the MNA
unit.
• Genetic lines of evidence indicated a moderate potential for the aerobic cometabolism of chlorinated ethenes under
all ISM Bio-Trap conditions.
• Total bacteria (EBAC) concentrations were measured on the order of 107 cells/bead in the MNA, BioStim and BioAug
units. With respect to specific microbial groups, sulfate-reducing bacteria (APS) were detected at a similar
concentration of 105 cells/bead in the MNA and BioAug units, while it was an order of magnitude higher in BioStim
unit (106 cells/bead). Methanogens were only detected in the BioAug unit at a concentration of 103 cells/bead,
whereas it was below the detection limit in the MNA and BioStim units.
Reductive Dechlorination
• Overall, QuantArray®-Chlor results indicated that the potential for the complete reductive dechlorination of
chlorinated ethenes was moderate under MNA, BioStim, and BioAug conditions.
– Dehalococcoides (DHC) is capable of mediating the complete reductive dechlorination of PCE to non-toxic
ethene. DHC was detected at a moderate concentration of 104 cells/mL in the MNA, whereas it was an order
of magnitude higher in the BioStim and BioAug units, i.e., 105 cells/bead. Concentrations of DHC in all ISM
units exceeded the threshold cell density (104 cells/mL) proposed by Lu et al. as a screening criterion for
generally useful rates of biological reductive dechlorination1.
– In addition, key dehalogenase genes (tceA reductase, bvcA, and vcrA vinyl chloride reductase genes) were
detected at concentrations of 103 cells/bead, 104 cells/bead, and 103 cells/bead, respectively, in the MNA
unit. In the BioStim and BioAug units, tceA reductase (103 cells/bead and 105 cells/bead, respectively), bvcA

(105 cells/bead, each), and vcrA (102 cells/bead, and 104 cells/bead, respectively) genes were detected.
Collectively, these results demonstrate that the genetic potential for the complete biodegradation of PCE to
ethene was moderate under all Bio-Trap units, and was enhanced under BioStim and BioAug conditions.
– Notable levels of other halorespiring genera were detected in all units.
o Dehalobacter (DHBt) was an order of magnitude higher in the BioStim and BioAug units (105
cells/bead) compared to the MNA unit (104 cells/bead). Dehalobacter DCM (DCM) and
Dehalogenimonas (DHG) genes were below the detection limits in all three ISM units.
Dehalogenimonas is known for dichloroelimination of chlorinated alkanes, but some strains have
been shown to be capable of reductive dechlorination of trans-1,2-dichloroethene and vinyl chloride.
o The concentration of Desulfitobacterium (DSB) was on the order of 105 cells/bead, in all Bio-Trap
units. Desulfitobacterium is capable of the reductive dechlorination of PCE and TCE to cis-DCE.
Desulfitobacterium strain PR sequentially dechlorinates 1,1,1-TCA to 1,1-DCA and chloroethane.
o Desulfuromonas spp. (DSM) was only detected in the BioAug unit at a high concentration of 106
cells/bead. DSM can mediate the anaerobic reductive dechlorination of PCE and TCE. Dehalobium
chlorocoercia (DECO) was measured at a moderate concentration of 104 cells/bead in the BioStim and
BioAug units, whereas it was not detected in the MNA unit. Dehalobium chlorocoercia DF-1 has been
shown to be capable of reductive dechlorination of chlorinated benzenes including
hexachlorobenzene, pentachlorobenzene, and tetrachlorobenzene.
– PCE Reductase gene (PCE-1) was only detected in the BioStim unit at a low concentration of 103 cells/bead.
• Contaminant analysis indicated that cis-DCE and vinyl chloride were the primary chlorinated compounds detected
in all units including the MNA unit (921 μg/L and 151 μg/L, respectively), BioStim unit (2440 μg/L and 2350 μg/L,
respectively), and BioAug unit (685 μg/L and 805 μg/L, respectively).
• The methane concentration was an order of magnitude higher in the BioStim (5000 μg/L) and BioAug (6000 μg/L)
units compared to the MNA (230 μg/L) unit, suggesting that environmental redox conditions were strongly
reducing and therefore, conducive to anaerobic reductive dechlorination. Ethene was detected in all ISM units with
higher concentrations of 240 μg/L and 140 μg/L in the BioStim and BioAug units, compared to 15 μg/L in the MNA
unit. Elevated concentrations of vinyl chloride and ethene daughter products suggested that complete reductive
dechlorination had occurred in the BioStim and BioAug units at a larger scale. Ethane was detected in BioStim and
BioAug units at concentrations of 18 μg/L and 16 μg/L, whereas its concentration was below the practical
quantitation limit in the MNA unit.
• The VFA analysis indicated that acetic acid and propionic acid concentrations were higher in the BioStim unit (50
mg/L and 5.8 mg/L, respectively) and BioAug unit (67 mg/L and 5.3 mg/L, respectively), relative to the MNA unit
where they were both below the practical quantitation limit. These results suggest that indigenous microorganisms,
and TSI DC culture were actively fermenting the electron donor components of the SRS amendment. These findings
were consistent with the elevated dissolved methane concentrations measured in the BioStim and BioAug units.
• Sulfate, which is an alternative electron acceptor used by other hydrogen-consuming microorganisms (e.g., sulfate-
reducing bacteria), was measured at low concentrations of 0.2 mg/L or less in all of the units. These data suggest
that competing alternative electron-accepting processes may not be impacting the consumption of hydrogen by
halorespiring bacteria in reductive dechlorination processes.
• Field parameters indicated that the groundwater pH of MW-3-S was 6.7, which is within the optimal range for
efficient growth of dechlorinating bacteria.

Aerobic (Co)Metabolism
• In general, the genetic potential for the aerobic cometabolism of chlorinated ethenes was moderate in all three Bio-
Trap units deployed in well MW-3-S.
– In the MNA unit, phenol hydroxylase (PHE) was detected at concentrations of 102 cells/bead, whereas PHE
was an order of magnitude higher in the BioStim and BioAug units (103 cells/bead). Toluene
monooxygenase (RMO) was measured at a similar concentration of 104 cells/bead in all ISM units, whereas
toluene monooxygenase 2 (RDEG) was only detected in the BioStim and BioAug units at a moderate
concentration of 104 cells/bead. Other functional genes involved in the aerobic cometabolism of chlorinated
ethenes were not detected, including toluene dioxygenase (TOD) and soluble methane monooxygenase
(SMMO).
• The ethene monooxygenase (etnC) gene and the epoxyalkane transferase (etnE) gene were measured on the order
of 103 cells/bead in the BioStim and BioAug units, suggesting that the potential for the aerobic oxidation of vinyl
chloride was moderate under these conditions. Only etnC (103 cells/bead) was present in the MNA unit.

MW-31-S MNA, BioStim, and BioAug Units
• Overall, QuantArray®-Chlor results indicated that the potential for the complete reductive dechlorination of
chlorinated ethenes was low under MNA and BioStim conditions and moderate under the BioAug condition.
• Genetic lines of evidence indicated that a moderate potential for the aerobic cometabolism of chlorinated ethenes
was present in all ISM units.
• Total bacteria (EBAC) were detected at high concentrations of 107 cells/bead in all ISM units. With respect to specific
microbial groups, APS concentrations were measured on the order of 105 cells/bead in the MNA and BioStim units,
whereas it was measured at a high concentration of 106 cells/bead in the BioAug unit. Methanogens were detected
at a concentration of 103 cells/bead in the MNA unit, while the methanogen concentration was an order of
magnitude higher in the BioStim and BioAug units, i.e., 104 cells/bead.
Reductive Dechlorination
• Overall, QuantArray®-Chlor results indicated that the potential for the reductive dechlorination of chlorinated
ethenes was moderate in all Bio-Trap units deployed at the MW-31-S well, and bioaugmentation with TSI DC
enhanced the genetic potential for complete reductive dechlorination of chlorinated ethenes and increased the
concentrations of key reductase genes during the deployment period over that observed under MNA conditions.
– DHC was detected at a low concentration of 102 cells/bead in the MNA and BioStim units, whereas it was
three orders of magnitude higher in the BioAug unit, measured at a moderate concentration of 105
cells/bead. In the BioAug unit, the DHC concentration exceeded the threshold cell density (104 cells/mL)
proposed by Lu et al. as a screening criterion for generally useful rates of biological reductive dechlorination.
However, in the MNA and BioStim units, the DHC concentrations fell below the threshold.
– With respect to key reductive dehalogenase genes, tceA was detected at a similar concentration of 102
cells/mL in the MNA and BioStim units, and 105 cells/mL in the BioAug unit. The vcrA gene was measured
at concentrations of 102 cells/bead in the MNA, 101 cells/bead in the BioStim, and 104 cells/bead in the
BioAug units deployed at the MW-31-S well location. The bvcA gene was not detected in any ISM unit.
Collectively, these results demonstrate that the genetic potential for the complete biodegradation of PCE to
ethene was low under MNA and BioStim conditions and moderate under BioAug condition.
– Moderate concentrations of other halorespiring genera were detected in all units.

o DHBt and DSB genes were present in all Bio-Trap units at moderate concentrations of 105
cells/bead. DCM was detected in the BioStim (103 cells/bead), and BioAug (104 cells/bead) units
and was below the detection limit in the MNA unit. The DECO concentration was similar in the
MNA and BioStim units (104 cells/bead), and an order of magnitude higher in the BioAug unit (105
cells/bead). DSM was only detected in the BioAug unit, at a high concentration of 106 cells/bead.
– PCE Reductase genes (PCE-1, and PCE-2) were below the detection limit in the BioStim and BioAug units,
and only PCE-1 was present in the MNA unit (103 cells/bead).
• Contaminant analysis indicated that cis-DCE was the primary chlorinated compound, followed by vinyl chloride, in
the MNA unit (544 μg/L and 7.5 μg/L, respectively), BioStim unit (468 μg/L and 9.5 μg/L, respectively), and BioAug
unit (237 μg/L and 17.4 μg/L, respectively). Elevated concentrations of vinyl chloride and ethene suggested that
some complete reductive dechlorination had occurred in all ISM units deployed at the MW-31-S location.
• Methane was present in all units at high concentrations: MNA (4,000 μg/L), BioStim (8,400 μg/L), and BioAug
(13,000 μg/L) units, suggesting that conditions in all units were strongly reducing and, therefore, conducive to
anaerobic reductive dechlorination. Ethene was present in all ISM units, with the highest detected in the BioAug
unit (36 μg/L).
• The VFA analysis indicated that acetic acid and propionic acid were detected in all ISM units, including the MNA
unit (140 mg/L and 17 mg/L, respectively), BioStim unit (110 mg/L and 18 mg/L, respectively), and BioAug unit
(110 mg/L and 31 mg/L, respectively). Butyric acid was only detected in the MNA unit (7.3 mg/L). The
concentrations of the other volatile fatty acids, including lactic acid, and pyruvic acid were below the detection limit
for all units deployed at MW-31-S.
• Sulfate was only detected in the BioStim unit at a concentration of 0.1 mg/L. These data suggest that competing
alternative electron-accepting processes may not be impacting consumption of hydrogen by halorespiring bacteria
in reductive dechlorination processes.
• Field parameters indicated that the groundwater pH of MW-31-S was 6.9, which is within the optimal range for
efficient growth of dechlorinating bacteria.
Aerobic (Co)Metabolism
• In general, the genetic potential for the aerobic cometabolism of chlorinated ethenes was moderate in all ISM units
deployed at the MW-31-S well location.
– Three of the five biomarkers for aerobic cometabolism of chlorinated ethenes were detected in all ISM units:
PHE, RDEG, and RMO were all detected at a similar concentration of 104 cells/bead in the MNA unit. In the
BioStim unit, both PHE and RDEG were detected at 103 cells/bead, whereas the RMO concentration was
measured at 104 cells/bead. For the BioAug unit, PHE, RDEG, and RMO were detected at concentrations of
104 cells/bead, 103 cells/bead, and 105 cells/bead, respectively.
• The etnC and etnE genes were only detected in the BioAug unit deployed in MW-31-S at concentrations of 103
cells/bead and 104 cells/bead, respectively.

Overview of Approach
Site managers have frequently turned to laboratory microcosms or small pilot studies to evaluate bioremediation. However,
duplication of in situ conditions in the laboratory is difficult and the results often do not correlate to the field. Pilot studies
are performed in the field but are often prohibitively expensive as an investigative tool. Bio-Trap studies serve as cost-
effective, in situ microcosms providing microbial, chemical, and geochemical evidence to evaluate biodegradation as a
treatment mechanism and to screen remedial alternatives.
Typically, each Bio-Trap Unit will contain samplers to evaluate the following:

How does it work?

The MICRO sampler (microbial populations) contains Bio-Sep® beads, an engineered composite of Nomex® and powdered
activated carbon which provides an incredibly large surface area (~600 m2/g) that is readily colonized by subsurface
microorganisms. In addition to a matrix for microbial growth, the Bio-Sep® beads can be “baited” with amendments
including electron donors (e.g., hydrogen releasing compounds) to investigate biostimulation approaches to enhance
biodegradation. The Bio-Trap units also contain a COC (contaminant of concern) sampler to measure contaminant
concentrations, daughter product formation, and dissolved gases and a GEO (geochemical fingerprint) sampler for
quantification of geochemical parameters (nitrate, iron, sulfate, etc.), chloride production, and metabolic acids (pyruvic,
lactic, acetic, propionic, etc.).

Bio-Trap® In Situ Microcosm studies at chlorinated solvent sites typically include three types of Bio-Trap Units deployed
within a monitoring well. Each Bio-Trap Unit corresponds to one of the three most common remedial options: monitored
natural attenuation (MNA), Biostimulation (BioStim), and Bioaugmentation (BioAug). All three Bio-Trap Units contain COC
and GEO samplers for chemical and geochemical analyses. The key difference between the Bio-Trap Units is in the MICRO
sampler.

Types of Bio-Trap Units typically deployed and MICRO sampler configurations:

MNA Unit: The purpose of the Control Bio-Trap Unit is to quantify contaminant degrading bacteria and daughter product
formation under monitored natural attenuation (MNA) conditions and to serve as a baseline for comparison to BioStim
and/or BioAug Units.

Following in-well deployment, DNA or phospholipid fatty acids (PLFA) can be extracted from the Bio-Sep beads for further
analysis. For example, DNA extracted from the Bio-Sep beads can be used in CENSUS analysis of Dehalococcoides (DHC)
and vinyl chloride reductase (bvcA and vcrA) genes to evaluate the potential for complete reductive dechlorination of PCE
to ethene under MNA conditions. The VOC and anion samplers can be used to determine concentrations of contaminants,
daughter products, dissolved gases, terminal electron acceptors, and chloride.

BioStim Unit: The Biostimulation Bio-Trap Unit is designed to test the hypothesis that electron donor addition will stimulate
growth of dechlorinating bacteria and enhance biodegradation. As with the MNA Unit, the BioStim Unit contains COC and
GEO samplers for chemical analyses. The BioStim Unit contains an amendment supplier to release the desired amendment
over the incubation time.

BioAug Unit: The Bioaugmentation Bio-Trap Unit is designed to evaluate bioaugmentation as a treatment technology. The
MICRO sampler contains Bio-Sep® beads pre-inoculated with the desired commercial culture. An amendment supplier may
also be used to deliver an amendment. As with the MNA and BioStim Units, the BioAug Unit also contains a COC and GEO
samplers for chemical analyses.

•Bio-Sep®beads contain no additional amendment and represent
current aquifer conditions.
Control
(MNA)
•An amendment supplier is used to release the desired specified
electron donor (sodium lactate, molasses, EVO, etc.) or electron
acceptor (oxygen release compound, sulfate, etc.).
Biostimulation

•Bio-Sep®beads are pre-inoculated with a bioaugmentation
culture, such as Dehalococcoides. These units can also be baited
with an additional amendment.

The QuantArray® Approach
Quantification of Dehalococcoides, the only known bacterial group capable of complete reductive dechlorination of PCE and
TCE to ethene, has become an indispensable component of assessment, remedy selection, and performance monitoring at
sites impacted by chlorinated solvents. While undeniably a key group of halorespiring bacteria, Dehalococcoides are not the
only bacteria of interest in the subsurface because reductive dechlorination is not the only potential biodegradation pathway
operative at contaminated sites, and chlorinated ethenes are not always the primary contaminants of concern. The
QuantArray®-Chlor not only includes a variety of halorespiring bacteria (Dehalococcoides, Dehalobacter, Dehalogenimonas, etc.)
to assess the potential for reductive dechlorination of chloroethenes, chloroethanes, chlorobenzenes, chlorophenols, and
chloroform, but also provides quantification of functional genes involved in aerobic (co)metabolic pathways for
biodegradation of chlorinated solvents and even competing biological processes. Thus, the QuantArray®-Chlor will give site
managers the ability to simultaneously yet economically evaluate the potential for biodegradation of a spectrum of common
chlorinated contaminants through a multitude of anaerobic and aerobic (co)metabolic pathways to give a much more clear
and comprehensive view of contaminant biodegradation.
The Chlorinated QuantArray® is used to quantify specific microorganisms and functional genes to evaluate the following:

How do QuantArrays® work?

The QuantArray®-Chlor in many respects is a hybrid technology combining the highly parallel detection of microarrays
with the accurate and precise quantification provided by qPCR into a single platform. The key to highly parallel qPCR
reactions is the nanoliter fluidics platform for low volume, solution phase qPCR reactions.

•Quantification of important halorespiring bacteria (e.g. Dehalococcoides, Dehalobacter, Dehalogenimonas, Desulfitobacterium spp.) and key functional genes (e.g vinyl chloride reductases, TCE reductase, 1,2-DCP reductase) responsible for reductive dechlorination
of a broad spectrum of chlorinated solvents.
Anaerobic Reductive
Dechlorination
•Several different types of bacteria including methanotrophs and some toluene/phenol utilizing bacteria can co-oxidize TCE, DCE, and vinyl chloride. The QuantArray®-Chlor quantifies functional genes like soluble methane monooxygenase encoding enzymes capable of co-oxidation of chlorinated ethenes.
Aerobic Cometabolism
•Ethene oxidizing bacteria are capable of cometabolism of vinyl chloride. In some cases, ethenotrophs can also utilize vinyl chloride as a growth supporting substrate. The QuantArray®-Chlor targets key functional genes in ethene metabolism.

How are QuantArray® results reported?
One of the primary advantages of the QuantArray®-Chlor is the simultaneous quantification of a broad spectrum of different
microorganisms and key functional genes involved in a variety of pathways for chlorinated hydrocarbon biodegradation.
However, highly parallel quantification combined with the various metabolic and cometabolic capabilities of different target
organisms can complicate data presentation. Therefore, in addition to Summary Tables, QuantArray® results will be
presented as Microbial Population Summary and Comparison Figures to aid in data interpretation and subsequent
evaluation of site management activities.

Interpretation
The overall purpose of the QuantArray®-Chlor is to give site managers the ability to simultaneously yet economically evaluate
the potential for biodegradation of a spectrum of common chlorinated contaminants through a multitude of anaerobic and aerobic
(co)metabolic pathways in order to provide a clearer and more comprehensive view of contaminant biodegradation. The following
discussion describes the interpretation of results in general terms and is meant to serve as a guide.
Reductive Dechlorination - Chlorinated Ethenes:While a number of bacterial cultures including Dehalococcoides,Dehalobacter,Desul-
fitobacterium, and Desulfuromonas spp. capable of utilizing PCE and TCE as growth-supporting electron acceptors have been isolated
[1–5],Dehalococcoides may be the most important because they are the only bacterial group that has been isolated to date which is
capable of complete reductive dechlorination of PCE to ethene [6]. In fact, the presence of Dehalococcoides has been associated with
complete reductive dechlorination to ethene at sites across North America and Europe [7], and Lu et al. [8] have proposed using a
Dehalococcoides concentration of 1 x 104 cells/mL as a screening criterion to identify sites where biological reductive dechlorination is
predicted to proceed at “generally useful” rates.
At chlorinated ethene sites, any “stall” leading to the accumulation of daughter products, especially vinyl chloride, would be a sub-
stantial concern. While Dehalococcoides concentrations greater than 1 x 104 cells/mL correspond to ethene production and useful rates
of dechlorination, the range of chlorinated ethenes degraded varies by strain within the Dehalococcoides genus [6, 9], and the pres-
ence of co-contaminants and competitors can have complex impacts on the halorespiring microbial community [10–15]. Therefore,
QuantArray®-Chlor also provides quantification of a suite of reductive dehalogenase genes (PCE, TCE, BVC, VCR, CER, and TDR)
to more definitively confirm the potential for reductive dechlorination of all chlorinated ethene compounds including vinyl chloride.
Perhaps most importantly, QuantArray®-Chlor quantifies TCE reductase (TCE) and both known vinyl chloride reductase genes (BVC,
VCR) from Dehalococcoides to conclusively evaluate the potential for complete reductive dechlorination of chlorinated ethenes to non-
toxic ethene [16–18]. In addition, the analysis also includes quantification of reductive dehalogenase genes from Dehalogenimonas spp.
capable of reductive dechlorination of chlorinated ethenes. More specifically, these are the trans-1,2-DCE dehalogenase gene (TDR)
from strain WBC-2 [19] and the vinyl chloride reductase gene (CER) from GP, the only known organisms other than Dehalococcoides
capable of vinyl chloride reduction [20]. Finally, PCE reductase genes responsible for sequential reductive dechlorination of PCE
to cis-DCE by Sulfurospirillum and Geobacter spp. are also quantified. In mixed cultures, evidence increasingly suggests that partial
dechlorinators like Sulfurospirillum and Geobacter may be responsible for the majority of reductive dechlorination of PCE to TCE and
cis-DCE while Dehalococcoides functions more as cis-DCE and vinyl chloride reducing specialists [10, 21].
Reductive Dechlorination - Chlorinated Ethanes:Under anaerobic conditions, chlorinated ethanes are susceptible to reductive
dechlorination by several groups of halorespiring bacteria including Dehalobacter,Dehalogenimonas, and Dehalococcoides. While the
reported range of chlorinated ethanes utilized varies by genus, species, and sometimes at the strain level, several general observa-
tions can be made regarding biodegradation pathways and daughter product formation.Dehalobacter spp. have been isolated that
are capable of sequential reductive dechlorination of 1,1,1-TCA through 1,1-DCA to chloroethane [13]. Biodegradation of 1,1,2-TCA
by several halorespiring bacteria including Dehalobacter and Dehalogenimonas spp. proceeds via dichloroelimination producing vinyl
chloride [22–24]. Similarly, 1,2-DCA biodegradation by Dehalobacter,Dehalogenimonas, and Dehalococcoides occurs via dichloroelimina-
tion producing ethene. While not utilized by many Desulfitobacterium isolates, at least one strain,Desulfitobacterium dichloroeliminans
strain DCA1, is also capable of dichloroelimination of 1,2-DCA [25]. The 1,2-dichloroethane reductive dehalogenase gene (DCAR)
from members of Desulfitobacterium and Dehalobacter is known to dechlorinate 1,2-DCA to ethene, while the 1,1-dichloroethane re-
ductive dehalogenase (DCA) targets the gene responsible for 1,1-DCA dechlorination in some strains of Dehalobacter. In addition to
chloroform,chloroform reductase (CFR) has also been shown to be responsible for reductivedechlorination of 1,1,1-TCA [26].
Reductive Dechlorination - Chlorinated Methanes:Chloroform is a common co-contaminant at chlorinated solvent sites and can
inhibit reductive dechlorination of chlorinated ethenes. Grostern et al. demonstrated that a Dehalobacter population was capable of
reductive dechlorination of chloroform to produce dichloromethane [27]. The cfrA gene encodes the reductase which catalyzes this
initial step in chloroform biodegradation [26]. Justicia-Leon et al. have since shown that dichloromethane can support growth of a
distinct group of Dehalobacter strains via fermentation [28]. The Dehalobacter DCM assay targets the 16S rRNA gene of these strains.
Reductive Dechlorination - Chlorinated Benzenes:Chlorinated benzenes are an important class of industrial solvents and chem-
ical intermediates in the production of drugs, dyes, herbicides, and insecticides. The physical-chemical properties of chlorinated
benzenes as well as susceptibility to biodegradation are functions of their degree of chlorination and the positions of chlorine sub-
stituents. Under anaerobic conditions, reductive dechlorination of higher chlorinated benzenes including hexachlorobenzene (HCB),

pentachlorobenzene (PeCB), tetrachlorobenzene (TeCB) isomers, and trichlorobenzene (TCB) isomers has been well documented [29],
although biodegradation of individual compounds and isomers varies between isolates. For example,Dehalococcoides strain CBDB1
reductively dechlorinats HCB, PeCB, all three TeCB isomers, 1,2,3-TCB, and 1,2,4-TCB [9, 30].Dehalobium chlorocoercia DF-1 has been
shown to be capable of reductive dechlorination of HCB, PeCB, and 1,2,3,5-TeCB [31]. The dichlorobenzene (DCB) isomers and
chlorobenzene (CB) were considered relatively recalcitrant under anaerobic conditions. However, new evidence has demonstrated
reductive dechlorination of DCBs to CB and CB to benzene [32] with corresponding increases in concentrations of Dehalobacter spp.
[33].
Reductive Dechlorination - Chlorinated Phenols:Pentachlorophenol (PCP) was one of the most widely used biocides in the
U.S. and despite residential use restrictions, is still extensively used industrially as a wood preservative. Along with PCP, the
tetrachlorophenol and trichlorophenol isomers were also used as fungicides in wood preserving formulations. 2,4-Dichlorophenol
and 2,4,5-TCP were used as chemical intermediates in herbicide production (e.g. 2,4-D) and chlorophenols are known byproducts
of chlorine bleaching in the pulp and paper industry. While the range of compounds utilized varies by strain, some Dehalococ-
coides isolates are capable of reductive dechlorination of PCP and other chlorinated phenols. For example,Dehalococcoides strain
CBDB1 is capable of utilizing PCP, all three tetrachlorophenol (TeCP) congeners, all six trichlorophenol (TCP) congeners, and
2,3-dichlorophenol (2,3-DCP). PCP dechlorination by strain CBDB1 produces a mixture of 3,5-DCP, 3,4-DCP, 2,4-DCP, 3-CP, and 4-CP
[34]. In the same study, however,Dehalococcoides strain 195 dechlorinated a more narrow spectrum of chlorophenols which included
2,3-DCP, 2,3,4-TCP, and 2,3,6-TCP, but no other TCPs or PCP. Similar to Dehalococcoides, some species and strains of Desulfitobacterium
are capable of utilizing PCP and other chlorinated phenols.Desulfitobacterium hafniense PCP-1 is capable of reductive dechlorination
of PCP to 3-CP [35]. However, the ability to biodegrade PCP is not universal among Desulfitobacterium isolates.Desulfitobacterium
sp. strain PCE1 and D. chlororespirans strain Co23, for example, can utilize some TCP and DCP isomers, but not PCP for growth [2, 36].
Reductive Dechlorination - Chlorinated Propanes:Dehalogenimonas is a recently described bacterial genus of the phylum Chlo-
roflexi which also includes the well-known chloroethene-respiring Dehalococcoides [23]. The Dehalogenimonas isolates characterized to
date are also halorespiring bacteria, but utilize a rather unique range of chlorinated compounds as electron acceptors including chlo-
rinated propanes (1,2,3-TCP and 1,2-DCP) and a variety of other vicinally chlorinated alkanes including 1,1,2,2-tetrachloroethane,
1,1,2-trichloroethane, and 1,2-dichloroethane [23].
Aerobic - Chlorinated Ethene Cometabolism:Under aerobic conditions, several different types of bacteria including methane-
oxidizing bacteria (methanotrophs), and many benzene, toluene, ethylbenzene, xylene, and (BTEX)-utilizing bacteria can
cometabolize or co-oxidize TCE, DCE, and vinyl chloride [37]. In general, cometabolism of chlorinated ethenes is mediated
by monooxygenase enzymes with “relaxed’ specificity that oxidize a primary (growth supporting) substrate (e.g.methane)
and co-oxidize the chlorinated compound (e.g.TCE). QuantArray®-Chlor provides quantification of a suite of genes encoding
oxygenase enzymes capable of co-oxidation of chlorinated ethenes including soluble methane monooxygenase (sMMO). Soluble
methane monooxygenases co-oxidize a broad range of chlorinated compounds [38–41] including TCE,cis-DCE, and vinyl chloride.
Furthermore, soluble methane monooxygenases are generally believed to support greater rates of aerobic cometabolism [40].
QuantArray®-Chlor also quantifies aromatic oxygenase genes encoding ring hydroxylating toluene monooxygenase genes (RMO,
RDEG), toluene dioxygenase (TOD) and phenol hydroxylases (PHE) capable of TCE co-oxidation [42–46]. TCE or a degradation
product has been shown to induce expression of toluene monooxygenases in some laboratory studies [43, 47] raising the possibility
of TCE cometabolism with an alternative (non-aromatic) growth substrate. Moreover, while a number of additional factors must be
considered, recent research under ESTCP Project 201584 has shown positive correlations between concentrations of monooxygenase
genes (soluble methane monooxygenase, ring hydroxylating monooxygenases, and phenol hydroxylase) and the rate of TCE
degradation [48].
Aerobic - Chlorinated Ethane Cometabolism:While less widely studied than cometabolism of chlorinated ethenes, some chlori-
nated ethanes are also susceptible to co-oxidation. As mentioned previously, soluble methane monooxygenases (sMMO) exhibit very
relaxed specificity. In laboratory studies, sMMO has been shown to co-oxidize a number of chlorinated ethanes including 1,1,1-TCA
and 1,2-DCA [38, 40].
Aerobic - Vinyl Chloride Cometabolism:Beginning in the early 1990s, numerous microcosm studies demonstrated aerobic ox-
idation of vinyl chloride under MNA conditions without the addition of exogenous primary substrates. Since then, strains of

Mycobacterium,Nocardioides,Pseudomonas,Ochrobactrum, and Ralstonia species have been isolated which are capable of aerobic
growth on both ethene and vinyl chloride (see Mattes et al. [49] for a review). The initial steps in the pathway are the monooxygenase
(etnABCD) catalyzed conversion of ethene and vinyl chloride to their respective epoxyalkanes (epoxyethane and chlorooxirane),
followed by epoxyalkane:CoM transferase (etnE) mediated conjugation and breaking of the epoxide [50].
Aerobic - Chlorinated Benzenes:In general, chlorobenzenes with four or less chlorine groups are susceptible to aerobic biodegra-
dation and can serve as growth-supporting substrates. Toluene dioxygenase (TOD) has a relatively relaxed substrate specificity
and mediates the incorporation of both atoms of oxygen into the aromatic ring of benzene and substituted benzenes (toluene
and chlorobenzene). Comparison of TOD levels in background and source zone samples from a CB-impacted site suggested that
CBs promoted growth of TOD-containing bacteria [51]. In addition, aerobic biodegradation of some trichlorobenzene and even
tetrachlorobenzene isomers is initiated by a group of related trichlorobenzene dioxygenase genes (TCBO). Finally, phenol hydrox-
ylases catalyze the continued oxidation and in some cases, the initial oxidation of a variety of monoaromatic compounds. In an
independent study, significant increases in numbers of bacteria containing PHE genes corresponded to increases in biodegradation
of DCB isomers [51].
Aerobic - Chlorinated Methanes:Many aerobic methylotrophic bacteria, belonging to diverse genera (Hyphomicrobium,Methylobac-
terium,Methylophilus,Pseudomonas,Paracoccus, and Alibacter) have been isolated which are capable of utilizing dichloromethane
(DCM) as a growth substrate. The DCM metabolic pathway in methylotrophic bacteria is initiated by a dichloromethane dehalo-
genase (DCMA) gene. DCMA is responsible for aerobic biodegradation of dichloromethane by methylotrophs by first producing
formaldehyde which is then further oxidized [52]. As discussed in previous sections, soluble methane monooxygenase (sMMO)
exhibits relaxed specificity and co-oxidizes a broad spectrum of chlorinated hydrocarbons. In addition to chlorinated ethenes, sMMO
has been shown to co-oxidize chloroform in laboratory studies [38, 41].

RE: Quantitative High Resolution Site Characterization Report
Siemens Energy Inc., Incident # 14285
5101 Westinghouse Blvd
Charlotte, North Carolina
Dear Mr. Reuscher,

AST Environmental, Inc. (AST) appreciates the opportunity collaborate with Hart & Hickman
(H&H) to complete the Quantitative High Resolution Site Characterization (qHRSC) at the above
referenced location. The proposed scope of work was to complete up to 20 soil borings to
approximately 35 ft-bgs and install temporary groundwater assessment wells adjacent to 10 of
those locations. The overall goal of this qHRSC program is to:

1. Define the impacted groundwater footprint
2. Quantify the total CVOC soil mass
3. Provide a visual interpolation of a high-resolution data set to aide in future investigation
and remedial activities.

REMEDIAL DESIGN CHARACTERIZATION

On Monday, July 10, 2023, AST mobilized to the site to begin direct push drilling with the Geologic
Exploration (GEX) drilling team and Hart & Hickman personnel. On July 10, AST marked boring
locations, and GEX began hand clearing borings to 5’ bgs. While preclearing borings, numerous
underground obstructions were encountered, including concrete and PVC/steel pipes. These
obstructions were not delineated during the site utility clearance. Additionally, two boring locations
(RDC-06 and RDC-13) were not completed due to underground utility encumbrances and spatial
limitations above ground. During the RDC event, a total of 19 soil borings were advanced via
direct push drilling by GEX using their Geoprobe 3230. 3.25-inch diameter direct push, dual tube
tooling was advanced in five-foot runs. Samples were collected every two feet beginning at
approximately 5’ bgs and all intervals were logged for lithology and PID readings were collected
to guide the sampling process. Soil samples were shipped to the RPI Project Support Laboratory
in Golden, CO for CVOC and Total Volatile Petroleum Hydrocarbon (TVPH) analysis via EPA
method 8260B. Although this data is used for injection design purposes, the lab is not a certified
or accredited laboratory, this data should not be used for regulator or compliance purposes.

AST encountered early refusal at 8 of the 19 boring locations; see table below for refusal depths.

Monitoring wells on site (MW-1-S, MW-3-S, MW-31-S) were purged and sampled on July 11,
2023. The purge volume was approximately 3 well volumes or until exhausted. Nine temporary
monitoring wells were installed in 5 soil boring locations; see table below for screen interval. These
wells were sampled on July 14, 2023.

Groundwater samples were shipped to the RPI Project Support Laboratory in Golden, CO for
CVOC and Total Volatile Petroleum Hydrocarbon (TVPH) analysis via EPA method 8260B, anions
via EPA method 300.1 and dissolved gases via EPA method RSK 175. Groundwater data has
been tabulated and is included in the attachments as Table 2.

GEX returned to site on July 17, 2023, to abandon all temporary wells with hydrated sodium
bentonite.

Boring logs for each location, along with TCE soil concentration strip logs, are included in
Attachment B.

3-Dimensional Quantitative Model

The soil data collected from the RDC program was loaded into Ejlskov Studio (ES), a proprietary
data visualization and acquisition software developed by Ejlskov A/S, a RPI Group member.
Once entered in the software, a 3-dimensional interpolation of the CVOC soil data was produced
by using the ES inverse distance algorithm. Due to the challenges of sharing a 3-d model, the
output of the data was shared via video conference with H&H on September 19, 2023. From the
review of this data, 2-dimensional figures of the PCE and TCE maximum soil concentrations, PCE
and TCE groundwater isoconcentration maps, and cross sections of both contaminant plumes
were created and are included in the Figures attachment.

Conclusions and Recommendations

The qHRSC program has significantly increased the definition of the subsurface soil and
groundwater contaminant footprints. No significant saturated soil was observed and the footprint
of the GCL PCE groundwater plume has been defined to the vicinity of MW-03S and RDC-04.

Based on the data generated during this qHRSC, along with input from Hart & Hickman during
the September 19 video conference call, AST has refined the initial CAT 100 injection design to
meet the goal or reducing all compounds to below GCL standards.

CAT 100 TECHNICAL INFORMATION

Remediation Products, Inc. (RPI) CAT 100 product is selected for its ability to manage high
concentrations of dissolved and sorbed halogenated and recalcitrant compound mass (e.g.
CVOCs, 1,4-Dioxane, Freons, etc.), mitigate daughter product generation/migration, and function
continuously in the subsurface for many years- all in a single injection event. The longevity of a
CAT 100 installation will be established during the Remedial Design Characterization (RDC)
process, which will determine product placement and loadings.

CAT 100 is a fusion of RPI’s BOS 100® and biotechnology. This combination of well-established
degradation technologies produces a product capable of achieving results beyond the capabilities
of either product by itself. A key characteristic of CAT 100 is the preservation of metallic iron within
the microporous structure of the carbon; it is not oxidized in the process of degrading chlorinated
solvents, rather it catalyzes the degradation without itself undergoing any permanent change.
During manufacture of BOS 100, the metallic iron partially dissolves into the carbon, creating an
electrical connection extending throughout the BOS 100 particle. As indicated on the product
description sheets for CAT 100, electron transfer is the heart of all contaminant degradation
processes and is promoted on the BOS 100® as the contaminant binds to the metallic iron
structure of the activated carbon.

Electron transfer, the heart of all contaminant degradation processes, is promoted as the
contaminant binds to the metal within the BOS 100 particle creating an electrical connection
extending throughout the activated carbon. An electron pump, created by the slow degradation of
complex carbohydrates and peptides, feed electrons to the conductor, which shuttles them to the
site of depletion. In this process, the metallic iron contained within the BOS 100 facilitates catalytic
degradation of contaminants without significant depletion of the iron. This overall cycle enables
degradation of far more contaminant mass than would be estimated by simple iron demand with
the BOS 100.

The biotechnology component of the CAT 100 utilizes two different facultative blends of
microorganisms. The first set is a blend of bacteria designed to degrade halogenated compounds
(e.g. Tetrachloroethylene (PCE), Trichloroethylene (TCE), and 1,1,1-Trichloroethane (1,1,1-
TCA)) and recalcitrant compounds (e.g. Carbon Tetrachloride (CT) and dioxanes (DX)). The
COC-degrading bacteria are entirely naturally occurring with no genetic modifications and have
been harvested from sites around the United States.

The second microorganism blend has a sole function to breakdown a supplemental complex
carbohydrate into low molecular weight compounds, e.g. lactate, acetate, and other readily
utilized substrate, that supports the first set of microorganisms that are degrading contaminants
of concern (COCs). These bacteria were originally developed for agricultural use and is widely
employed across the United States. Biochemically, the second set was developed to facilitate re-
uptake of cellulosic plant matter into the soil, replenishing essential nutrient and minerals
supporting future generations of crops. It is for these properties the blend was included in CAT
100 to produce food and nutrient that can be beneficially used by other organisms in the
degradation of halogenated and other contaminants.

Succinctly, the most important aspect of the biological activity is to produce electrons through
assimilation and breakdown of the complex carbohydrate. It is these electrons that are shuttled
by the activated carbon to the point of degradation within the microporous structure of the BOS
100 where the chlorinated compounds are bound to nano-scale deposits of metallic iron. Thus,
the BOS 100 component of CAT 100 plays a critical role in the time required to treat the mass at
the site. The more BOS 100 in the formation the larger the platform for the degradation process
to occur speeding up the overall remedial time to achieve the targeted goals.

Dear John Reuscher:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 7/14/2023 for the analyses presented in the
following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the
analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136
Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time.
Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to
the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information. Sincerely,
Angela D Overcash Senior Project Manager

BOS 100 and CAT 100 Product Sheets
Brief Description of BOS 100®

BOS 100®

BOS 100® is a specialized catalyst manufactured by Remediation Products Inc
and designed for rapid degradation of chlorinated solvents. The product consists of
activated carbon that has been impregnated with metallic iron. The manufacturing
process results in an extremely large (metallic iron) surface area that is highly active.
Typically, the product is mixed with water and the resulting slurry is then injected using
high pressure pumps although it has also been placed into excavations to address residual
solvent impacts. Hydraulic fracturing is normally employed to enhance its distribution
and place the material throughout the impacted formation. Since the product is granular,
in clay/silt formations its installation results in seams of material that form preferential
pathways throughout the formation. This enhances contact and provides a long-term
mechanism for “effective contact” and this mechanism remains active for an indefinite
period of time. In sands or sandy soils, fairly uniform distributions are possible.

First, contaminants are “trapped” by the activated carbon and then degraded by
reaction with the metallic iron. As manufactured, the product contains roughly 6.5% (wt)
metallic iron. Reaction byproducts include low levels of dissolved iron, chloride, and a
series of non-toxic and generally unregulated hydrocarbon gases such as ethylene, and
methane. A summary of performance characteristics is provided in the following items.

1. It is not necessary to wait for extended periods of time to know if the desired
effect will take place. When properly installed, groundwater concentrations of
site contaminants will be significantly reduced within a matter of days.
2. The product does not depend on any bacterial action to support its activity. The
process is entirely based on chemical reaction.
3. Unlike bacterial mechanisms, the product is not sensitive to local geochemistry
and will work just as well when oxidation-reduction potential is negative as when
it is positive. For bacterial reductive dechlorination to function well, this
parameter (ORP) must have a fairly large negative value.
4. BOS 100® is able to effect rapid reduction of contaminants in groundwater due to
the fact it contains a substantial amount of activated carbon. This is the “trap”
portion of the products activity. Activated carbon has a tremendous affinity for
organic compounds and rapidly adsorbs contaminants from groundwater or from
unsaturated soils.
5. The product is granular and when injected acts as a propant, that establishes
permanent seams within clay soils that become preferential pathways for
groundwater seep. This is tremendously advantageous in clays as contamination
will migrate into these pathways and come into immediate contact with treatment.
6. The product possesses an extremely high reactivity toward chlorinated solvents.
This reactivity is due to a highly active and large available surface of metallic iron
(roughly 250 m2/gm-iron). The available surface area is at least ten times as large
as that available from any other source of iron, including the most active forms of
“nano-scale” iron suspensions.
7. Rates of dechlorination are strong functions of both the surface area per gram iron
but also on the local concentration of contaminants. The higher the concentration
the higher the rate of degradation. With conventional iron powders or products
such a HRC®, this concentration is simply that observed in the groundwater.
With BOS 100®, the concentration of interest is that inside the activated carbon
and this will be 50 to 100 times what existed in the groundwater.
8. Rates of contaminant degradation are easily 100 times as fast as those achievable
by other technologies. This results in clean-up cycles of weeks to months instead
of years.
9. Toxic daughter products such as vinyl chloride are not a problem since these
compounds remain locked up within the carbon and are subsequently degraded.
Since groundwater can be cleaned to targeted standards within very short periods
of time and is maintained at this level throughout the clean-up lifetime, closure
monitoring can commence within a short time after installation.
10. Construction activities associated with property redevelopment can be performed
without concern as groundwater is clean and there has been no contribution of
carcinogenic byproducts to the soil vapor.
11. The product is not water soluble so no dilution or movement of the product takes
place after installation. Consequently, no long term contingency for re-treatment
is required. Any re-treatment that might be needed can be accomplished within
the first few months during active remediation.
12. In barrier applications, the BOS 100® performs very much like an in situ carbon
bed on steroids. This is because it not only absorbs the contaminants, it also
rapidly destroys them so the expected lifetime of the carbon bed is substantially
extended over that of carbon alone.

CAT 100 Product Description
CAT 100 is a fusion of RPI’s BOS 100® and biotechnology to produce a technology capable of
achieving results beyond the capabilities of either one alone. Electron transfer, the heart of all
contaminant degradation processes, is promoted as the contaminant binds to the metal creating an
electrical connection extending throughout the carbon. An electron pump created by slow deg-
radation of complex carbohydrates and peptides feeds electrons to the conductor which shuttles
them to the site of depletion. In this process the metallic iron facilitates catalytic degradation of
the contaminant without significant depletion of the iron. This overall cycle enables degradation of
far more contaminant mass than would be estimated by simple iron demand.
CAT 100 Product Applications
The product is typically mixed with water to create a slurry that can be applied using a variety of
techniques including: Direct push injection, soil mixing techniques, and trenching. It is commonly
employed in plume wide treatment including treatment of source, mid, and downgradient plume
regions. Plume area treatment is normally accomplished using slurry injection across the impact-
ed thickness at a number of points located using a triangular grid pattern. Effective barriers can
be constructed by injection using a tight point grid layout or through trenching or soil mixing.
Specialized injection techniques have been developed to address a variety of lithologic settings.
CAT 100 was quietly introduced to last year and has now been used at multiple sites in the USA
and Europe. These sites were impacted by NAPL and principal contaminants include carbon
tetrachloride and associated daughters, TCE, PCE, and a complex spectrum of halogenated and
non-halogenated compounds.
RPI Group
RPI Group is comprised of Remediation Products, Inc. (RPI) and a group of select remediation
contractors that employ a three-pronged approach to ensure success: High density soil and
groundwater sampling to support detailed conceptual site model development, expert design,
and proven installation techniques to ensure distribution of the CAT 100 in the targeted
intervals. The RPI Quality Assurance Laboratory located in Golden, CO provides cradle to grave
analytical support throughout the project at no charge to the client. AST Environmental (AST)
acts as RPI’s Distributor & Training Affiliate for the installation contractors. A list of the
contractors can be found at RPI’s website..
