Peerless Cleaners from 1979 to 1982, and A Cleaner World from 1982 to 1991. In 1991 the former building was
demolished during the widening of High Point Road and the existing building was constructed. A Cleaner World
then continued drycleaning operations in the existing building. A Cleaner World ceased drycleaning operations
in 2004 and the machinery was removed in 2005. However, the facility continued to operate as a drop-off
station. A suspected release was reported based on a soil sample collected near the drycleaning machine by

A Cleaner World #162 Injection Permit Application
ATC Project No. 45.34341.4124 April 9, 2010
A. SM HISTORY
(1) Site Usage Historically and Present
The property at 4506 High Point Road in Greensboro, North Carolina was first utilized for dry
cleaning operations in 1959. The previous building was occupied by Fordham's Inc. (dry
cleaning business) from 1959 to 1979, Peerless Cleaners from 1979 to 1982, and A Cleaner
World from 1982 to 1991. In 1991 the former building was demolished during the widening of
High Point Road and the existing building was constructed. A Cleaner World continued
operations in the existing building. A Cleaner World ceased drycleaning operations in 2004 and
the machinery was removed in 2005. However, the facility continued to operate as a drop-off
station. A suspected release was reported by Shield Environmental in October 2005. In March
2008, drycleaning operations resumed at the site under new management. The current property
owner and drycleaning business operator is Mi J. Kim. The name of the current drycleaning
operation is $1.50 Cleaner.
(2) Origin of the Contamination
A Phase I Environmental Site Assessment (ESA) was prepared for Sarah Chi, a prospective
purchaser of the property, on August 26, 2004, by Pyramid Environmental and Engineering P.C.
Based on this report, the 3,948 square foot commercial building that is presently on the site was
built in 1991 by ACW Management Corp. and had been occupied by A Cleaner World since
construction. A former building was located on -site, but was demolished when High Point Road
was widened in 1991. The farmer on -site building was operated as a dry cleaning business since
1959. The earliest property listing in the city directory was 1958 when the property was listed as
Free Howard Trucking. Historical aerial photographs showed that the former commercial
building was constructed prior to 1937.
The 2004 Phase I ESA identified three recognized environmental conditions (RECs) for the site.
The first REC was the on -site dry cleaning operations. The second REC was a 1,000-gallon
heating oil underground storage tank (UST) utilized on -site from at least 1982 through 1991. The
UST was removed during site redevelopment activities in 1991, but no closure samples were
collected to evaluate whether a petroleum release may have occurred. Note that later sampling by
ATC showed no significant petroleum contamination attributable to the former heating oil UST.

A Cleaner World #I62 Injection Permit Application
ATC Project No. 45,34341 A124 April 9, 2010
The third REC was a reported release incident on the adjacent property to the south (currently
High Point Road Self -Storage). This property was formerly occupied by Pfizer, Inc, and was
listed on the federal Comprehensive Environmental Response Compensation and Liability
Information System (CERCLIS) list and the State Inactive Hazardous Sites (IHS) list. Later
sampling and a file review by ATC also showed that this property is not significantly contributing
to the drycleaning solvent plume originating at the subject site.
As part of the entry requirements for the ❑SCA program, Shield Engineering Inc. collected a soil
sample (SS-1) from inside the building on September 29, 2005. The depth at which the sample
was collected is unknown. The analytical results from the soil sample indicated detectable vinyl
chloride, cis- l,2-diebloroethene, trichloroethene (TCE), tetrachloroethene (PCE), total xylenes, n-
propylbenzene, 1,3,5 trimethylbenzene. and 1,2,4-trimethyibenzene. The drycleaning business
owner and property owner at the time, ACW Management Corporation, subsequently submitted a
petitioner questionnaire for certification of the site into the ❑SCA Program. The site was
subsequently certified on November 1, 2005, and an Assessment and Remediation Agreement
was executed.
Between August 2006 and August 2008, ATC Associates of North Carolina, P.C. (ATC), under
contract to the DSCA Program, completed assessment activities to delineate the extent of
contamination associated with the release. A total of 55 soil borings have been advanced and 30
monitoring wells have been installed. The results of the assessment indicated that chlorinated
solvent constituents are the primary contaminant of concern for the site. A plume of PCE extends
over 1,000 feet downgradient southeast. Maximum PCE concentrations in the source area are on
the order of 1.5 mg/L. Vertically, the plume has impacted both the overburden and the bedrock
aquifers. The downgradient edge of the plume intercepts a downgradient stream. Sampling of
the stream has indicated constituents of concern above NC 2B Surface Water Standards. Na
water supply wells have been identified in the site vicinity that could be impacted by the release.
Note that additional monitoring well installations are planned to fully delineate the extent of
contamination. Refer to the tables and figures contained in this permit application for additional
details regarding the assessment data collected to date. The results of ATC's assessment were
documented in a Prioritization Assessment Report dated October 21, 2006, two Assessment
Reports dated March 6, 2008, and September 19, 2008, and a Groundwater Monitoring Report
dated March 3, 2009.

A Cleaner World 4162 Injection Permit Application
ATC Project No. 44.34341.4124 April 9. 2010
A Tier i and 2 Risk Assessment was completed in February 2009 to evaluate the risk posed by
the contamination and goals for remediation. The protocol for the risk assessment was in
accordance with the DSCA Program's risk -based rules. Based on the results of the risk
assessment and subsequent discussions with the ❑SCA Program, a level of 0.134 mglL for PCE
in groundwater (Source Groundwater Protective of Surface Water) was selected as the goal for
groundwater remediation. This permit application covers the completion of a pilot test to
evaluate whether EHC® is successful at reducing contaminant concentrations. If this technology
is successful, ATC will request approval for full-scale injection to achieve the remedial goal.
Note that soil excavation is also currently planned to address soil impacted above risk -based
remedial goals.
(3) Previous Remedial Action(s)
To date, no remedial action has occurred at the site.
B. HYDROGEOLOGIC DESCRIPTION
(1) The Regional or Geologic Setting
25
According to the North Carolina Geologic Map (1985), the site is located within the Carolina Slate
Belt of the Piedmont Physiographic Province. The bedrock underlying the site is "Metamorphosed
Granitic Rocle' (CZg) that is megacrystic, well foliated, and locally contains hornblende.
(2) Significant Changes in Lithology
Based on soils encountered during drilling activities, site soils consist primarily of an interbedded
mixture of sand, silt, and clay, generally coarsening with depth to partially weathered rock
(saprolite) and bedrock. The soils at this site are Enon Urban -land complex — a product of
weathering of the underlying rock, and urban development. The transition from competent
bedrock to weathered rock to residual sail is gradual. Competent metamorphosed granite bedrock
was encountered during drilling activities at the site at depths ranging from 12 to 73 feet below
ground surface (bgs).

ATC Project No, 45,34341,4124 April 9, 201❑
(3) Hydrogeologic Parameters
Based on recent and historical groundwater elevation data, the direction of groundwater flow
across the site is divided. The primary direction of plume migration coincides with groundwater
flow to the east-southeast at a hydraulic gradient of 0.02, based on the groundwater elevations for
monitoring wells MW-1 and MW-16S in December 2008. A secondary direction of plume
migration coincides with groundwater flow to the west-northwest at a hydraulic gradient of0.018,
based on the groundwater elevations for monitoring wells MW-1 and MW-9 in December 2008.
Two streams are located downgradient of the site to the east-southeast and west-northwest in the
two directions of groundwater flow.
Shelby tube samples were collected from the subject site for analysis of physical soil parameters.
Based on Shelby tube data for the 15 to 17-foot interval below the water table, the total porosity
is estimated at 35.1 percent and the effective porosity, generally equivalent to specific vield, is
estimated at 18.8 percent.
Slug tests were also conducted at the site in August 2008. Evaluation of the slug test data using
the Bower -Rice and Hvorslev methods indicated a range in hydraulic conductivity values of
0.269 to 0.781 fdday for the unconsolidated zone and 0.43 to 3.14 ft/day for the bedrock zone.
Based on the geometric mean of hydraulic conductivity values for the unconsolidated zone (0.453
ft/day), a hydraulic gradient of 0.02, and an effective porosity of 18.8 percent, the average
groundwater flow velocity in the unconsolidated zone is estimated at 0.05 ft/day (17.6 fflyr).
Based on the geometric mean of hydraulic conductivity values for the unconsolidated zone (0.453
ft/day) and an estimated aquifer thickness of 24 feet (approximate depth to bedrock minus depth
to water in the source area), the average transmissivity of the aquifer is estimated at 16.3 fi /day.
(4) Depth to Mean Seasonal High Water Table
Based on recent and historical depth to groundwater measurements. tile depth to groundwater
across the site varies from 2.16 to 19.74 feet bgs across the contaminant plume. In the area of the
proposed remediation activities (source area), the depth to groundwater ranges from
approximately 14 to 16 feet bgs.

ATC Project No. 45.34341A124 April 9, 2010
C. INJECTION FLUJD COMPOSITION
The proposed injectant is a product developed by Adventus Group called EHCR. EHC® is a
patented combination of controlled release carbon and zero valent iron (ZVI) particles used for
stimulating the in -situ chemical reaction of organic compounds in groundwater. EHC® is a
nutrient rich product that stimulates bacterial growth in groundwater, which in turn reduces the
redox potential in the subsurface environment. The bacteria ferment carbon and release voiltle
fatty acids which serve as electron donors for other bacteria. The ZVI stimulates dechlorination
and additionally reduces the redox potential in the subsurface. A Material Safety Data Sheet for
EHCS is included in Appendix 3.
D. INJECTION RATIONALE
(1) Remedial Goals
Based on the results of a Tier 2 risk assessment, the cleanup goal for groundwater remediation is
0.134 mg/L for PCE. The horizontal extent of groundwater impacted above this remedial goal
extends from the source area approximately 750 feet to the southeast. The vertical extent of
groundwater impacted above the remedial goal encompasses both the unconsolidated and bedrock
aquifer zones. This permit application covers completion of a pilot test to evaluate the
effectiveness of EHCID for groundwater remediation. For the pilot scope, one permeable reactive
barrier (PRB) will be installed downgradient of the source area. The vertical extent of impact to
be addressed with the pilot injection extends from approximately 14 to 38 feet bgs. Based on the
success of the initial injection, ATC may request approval for full-scale injection to achieve the
remedial goals.
(2) Contaminant 1 Injectant Reactions
As discussed in Section C, the proposed injectant is a product called EHC9 developed by
Adventus Group. EHC` is a source of both organic carbon and ZVI. The organic component of
EHC® is a fibrous organic material that is nutrient -rich, hydrophilic, and has high surface area.
The EHC® stimulates the biological community releasing a variety of volatile fatty acids (for
example acetic, propionic, butyric). The ZVI component stimulates direct chemical

ATC Project No. 45,34341.4124 April 9, 2010
dechlorination and an additional drop in the redox potential of the groundwater via chemical
oxygen scavenging. These physical, chemical, and biological processes combine to create an
extremely reduced environment that stimulates chemical and microbiological dechlorination of
otherwise persistent compounds. Additional details regarding reactions between the EHC" and
contaminants are included in Appendir 4.
(3) Summary Results of Previous Modeling or Testing
Available case studies and product literature are included in Appendix 4 of this permit
application.
INJECTION PROCEDURE AND EQUIPMENT
(1) Construction Plans & Materials
The injection site is approximately 2,000 square feet in area and is planned to be treated with a
total of 20 direct -push injection points. The injection points will be aligned in a PRB array
downgradient of the source area on -site. The injection depths will extend from the water table at
approximately 14 feet bgs to direct push refusal, which is estimated at 38 ft bgs. However, note
that the total injection depth may be slightly more or less depending on the encountered depth of
direct -push refusal. A total volume of 5,653 gallons of injectate slurry is planned for the targeted
area. The injectate slurry will be composed of 15,500 lbs of EHC", mixed with 4,653 gallons of
water (775 lbs EHC'o and 233 gallons of water in each of 20 points). The target area and
proposed injection points are shown in Figure 3.
(2) Operation Procedures
Injection will be accomplished using a direct -push drilling rig. The direct -push rig will be equipped
with the tooling typically required for injection activities. A diagram of the injection system is
included in Appendiv 5 and the injection process is described below.
At the start of the injection, measured amounts of municipal water, EHO will be added to the
onboard slurry mixing tank and the mixer/pump will be started. The injection rod will consist of a
1.5-inch outside diameter Geoprobe drill rod driven to the desired injection depth using a direct -push

ATC Project No, 45.34341 A124 April 9, 2010
drilling rig. A high pressure hose will extend from the mixing tank, to the injection pump, then to a
quick connect coupling on the injection rod, The injection rod assemblage is equipped with a shut-
off valve at the surface, and an injection head at the injection depth. An expendable point is present
which seals the injection head until the desired injection depth is reached. Once the injection depth is
reached, the injection pump is engaged, the injection head valve is opened, and the expendable point
is shed to facilitate injection.
Injection will he performed using a bottom up approach. Injection pressures and flow rates are site
specific and will be determined after the first few locations are completed. The injection pressure
will be monitored continuously using a pressure gauge and the injection rate will be adjusted
using the injection pump and valves. After injection at a desired depth is complete. the rod string
will be pulled up into the next injection zone. If it is necessary to break a rod and back pressure
exists, the pressure will be relieved into a bucket and dumped back in the pump hopper. Once
injection at a Iocation is complete, the residual pressure in the formation will be monitored until a
safe level is reached. The injection rod will then be withdrawn and the boring will be abandoned
using hydrated bentonite.
(3) Diagrams & Figures
A diagram of the proposed injection system is provided in Appendix 5,
(4) Planned Injection Schedule
The injection is expected to take approximately six days total. We anticipate mobilizing to the site to
begin field activities within four weeks of approval of necessary permits.
F. MONITORING PLAN
(I) Existing and Proposed Monitoring Wells
Groundwater samples will be collected from monitoring wells MW-1, MW-2, MW-3, MW-IOS,
MW-18S, and MW-18D to monitor the effectiveness of the injection activities. Groundwater
samples will be analyzed for volatile Organics by EPA Method 8260. In addition, to monitor
parameters related to reductive dechlorination and the injected fluids, groundwater samples will

11
A Cleaner World 4162
ATC Project No. 45.34341.4124
Injection Penn it Application

be analyzed for nitrate, sulfate, methane, ethene, ethane, iron, calcium, magnesium, manganese,
and total organic carbon (TOC). Field sampling will also be conducted for dissolved oxygen,
oxidation/reduction potential, specific conductivity, pH, temperature, and total and dissolved iron.
(3) Sampling Schedule
Groundwater samples will be collected from the wells specified above prior to injection and one
month, three months, six months, and one year following injection.
G. WELL DATA
Well construction details for the existing monitoring wells are included in Table 3. Historical
receptor surveys conducted at the site did not identify water supply wells within 1,500 feet of the
site.

Subject: Revised Proposal - Treatment of CVOCs using EHCO ISCR Technology
Dry Cleaner, Greensboro, NC
Adventus Proposal No. AA19-370
Dear Genna:
Please find herewith a conceptual remedial design and cost estimate for employing EHC® in
sits chemical reduction (ISCR) technology to remove chlorinated volatile organic compounds
(CVOCs) from groundwater at the above referenced site (the Site). The cost estimate
includes EHC amendments and delivery (estimated); Adventus on -site field support for the
initiation of the project is presented as a recommended option. This proposal has been
updated form the one provided on May 29, 2009.
TECHNOLOGY BACKGROUND
EHC® is the original, patented combination of controlled -release carbon and zero valent iron
(ZVI) particles used for stimulating in situ chemical reduction (ISCR) of otherwise persistent
organic compounds in groundwater. Variations of these materials have been used to treat
over 8,000,000 tons of soil/sediment impacted by recalcitrant compounds as part of the
company's ❑ARAMEND6 bioremediation technology. Both EHC and DARAMEND are
proven, established technologies that have been used at hundreds of sites to date
throughout the world. The technologies have been accepted and many Federal, State
(including California), and regional regulatory authorities within the USA/Canada (Figure 1a)
Europe (Figure 1b) and other places around the world.
EHC is available as a solid or liquid material that can be easily injected into the subsurface
environment in a variety of ways, based on site -specific designs. Application methods include
direct mixing, hydraulic fracturing, pneumatic fracturing, and injection of slurries or liquids.
Direct placement in trenches and excavations are also reliable application methods.

Following placement of EHC into the subsurface environment, a number of physical,
chemical and microbiological processes combine to create very strong reducing conditions
that stimulate rapid and complete dechlorination of organic solvents and other recalcitrant
compounds. First. the organic component of EHC (fibrous organic material) is nutrient rich,
hydrophilic and has high surface area; thus, it is an ideal support for growth of bacteria in
the groundwater environment. As they grow on EHC particle surfaces, indigenous
heterotrophic bacteria consume dissolved oxygen thereby reducing the redox potential in
groundwater. In addition, as the bacteria grow on the organic particles, they ferment carbon
and release a variety of volatile fatty acids (acetic, propionic, butyric) which diffuse from the
site of fermentation into the groundwater plume and serve as electron donors for other
bacteria, including dehaiogenators and halorespiring species. Finally, the small ZVI particles
provide substantial reactive surface area that stimulates direct chemical dechlorination and
an additional drop in the redox potential of the groundwater via chemical oxygen scavenging.
These physical, chemical and biological processes combine to create an extremely reduced
environment that stimulates chemical and microbiological dechlorination of otherwise
persistent compounds. Redox potentials as low as —550 mV may be observed in
groundwater after EHC application. At these Eh levels, many organic constituents of interest
(COI) are thermodynamically unstable and they will readily degrade via pathways more
typical of physical destruction processes (minimum production and no accumulation of
typically recognized biodegradation intermediates such as QCE for TCE). Hence, the ISCR
technology is microbiologically based in that we rely on indigenous microbes to biodegrade
the EHC carbon (refined plant materials), but we do not require the presence or activity of
special or otherwise unique bacteria for complete and effective remediation.
AA19-370 2

AD Y E 1 V 1 U EHC Cyst Estimate
The type of EHC used for a given site depends, in part, on the construction method
employed to emplace the material into the subsurface. If a direct mixing or direct placement
method is used, the standard slow release, solid EHC material would likely be utilized. If an
injection method is used, however, a combination of fast and slow release EHC may be
preferred. If the material is to be placed through an existing well network, then a water-
soluble, aqueous formulation, EHC-A, may be utilized.
In either event, the fibrous organic carbon and ZVI or other reduced metal that comprises the
slow release EHC will remain in the location where it is injected. It will not only treat COI that
migrates into the treated area, but it will also have a 'halo' or 'zone of influence' of low redox
conditions that will extend beyond its physical space, greatly increasing its effectiveness.
Figure 2 shows how EHC injection creates a wide zone of influence outside of its
immediate location. The native soil color is the yellow visible on the right hand side of the
core. The orange discoloration is due to the low redox conditions created by the EHC, which
became apparent after exposure to the air for 2 hours.

MODE OF ACTION -- ISCR FOR CVOCs
It is critical to understand that the processes of C01 destruction under ISCR conditions are
different from the typical pathways. The primary COls in the Site groundwater are PCEfTCE
and the recognized daughter products of reductive dehalogenation reactions that occur
under normal anaerobic conditions (Figure 3).

Under ISCR conditions (Eh <-550 mV), these pathways are avoided and terminal destruction
/ mineralization proceeds along the lines of the recognized beta -elimination pathways
(Figure 4). These differences have been described by various experts in the field of
biotransformation processes (e.g., Dr. John Wilson, US EPA as reported in the AFCEE
Technology Transfer Seminar, 2003; Dr. Marls Ferry, MPCAA; J, Szecsody and J. Fruchter et
al., Battelle Pacific Northwest National Laboratory).

CASE STUDIES
EHC treatment has effectively removed a range of CVOCs under full-scale field conditions
without generation of potentially problematic catabolites (Appendix A)--

• EHC-M for isolated hotspot treatment (TCE and Cr(VI)), NW USA
• EHC for source area mass reduction (TCE. TCA and catabolites), Cherry Point. North

• EHC trench PRB and excavation backfill (PCE and daughters), confidential site,
Texas
■ EHC applied via hydraulic fracturing into partially weathered rock, confidential site,
Manufacturing facility, North Carolina
Of particular interest is the fact that EHC treatment has been proven effective at sites with
both very high and very low initial CVOC concentrations. Such broad applicability is
consistent with the multiple modes of dechlorination that are generated by a combined
chemical/microbiological approach to groundwater treatment.
EHC and other Adventus products have been accepted by many regulatory agencies -
(http://www.adventusgroup.com/library/regulatory-approvals.shtmi). The product is
supplied in 50 lb bags as a powder which can be mixed with soil or slurried in water.
Installation techniques vary widely depending on the application. For example, the powder
can be mixed with soil and placed at the bottom of an excavation where prior soil removal
had been conducted. A slurry can be made and the mixture can be injected into the
subsurface using techniques such as direct injection through GeoProbe rods or hydraulic
fracturing (Appendix B).
POTENTIAL ADVANTAGES OF USING EHC ISCR TECHNOLOGY
The patented combination of controlled -release organic carbon plus ZVI uniquely yields
ISCR conditions which give EHC powerful technical advantages over other materials that
provide only carbon (i.e., emulsified oils, molasses or lactate -based substrates) or only ZVI.
These include:
• Health and Safety. Safe handling and easy application with no bulky or hazardous
material disposal issues;
AA19-370

(6��) ADVENTUS
EHC Cost Estimate
• Minimal Methane Production. The presence of ZVI and the complex, controlled -
release carbon source help minimize production of potentially problematic
fermentation end -products, such as methane;
Predictable Performance. EHC uniquely integrated chemical and microbiological
degradation processes which allows treatment to proceed at a predictable rate:
• Constructability. EHC is easily and quickly injected using conventional construction
technologies;
• No Mobilization of Contaminants, optimal volume of EHC slurry is injected without
the need for extensive water flushing, which avoids potential displacement and
mobilization issues;
• Accelerated Site Closure due to the ability of the EHC system to rapidly remove COI
mass via a combination of biogeochemical degradation processes without relying
on physical sorption 1 sequestration as a major "removal" mechanism, ala oils;
■ 1SCR- Combined chemical and biological oxygen scavenging facilitates rapid oxygen
consumption and establishment of reduced Eh; Generation of significantly lowered
reducing conditions usually eliminates any requirement for specialty microorganisms
or inoculants;
• No Dead -End Intermediates. Rapid COI removal without accumulation of potentially
problematic catabolites, such as cis DCE from TCE or chloroform (CF) from carbon
tetrachloride (CT) (see ❑olfing et a!, 2008; Liu et al., 2000)
• Applicability. Demonstrated effective on a wide range of COI, including chlorinated
solvents, Freons, pesticides, perchlorate and other energetic compounds
(explosives);
• Longevity with no Rebound. EHC remains active in the environmental for 12 to 60
months hence COI rebound phenomena are not observed (rebound is common when
using readily biodegradable, liquid substrates);
• Complete Technology. Provision of major, minor and micronutrients that are
essential to the activity of fastidious anaerobic bacteria involved in recognized
dechlorination reactions;
• Buffering Capacity- Provision of substantial pH buffering capacity (i.e., different EHC
products are designed to release alkalinity, acidity or to maintain a neutral pH). In
contrast, the addition of conventional organic substrates (e.g., emulsified oils,
molasses or lactate -based materials) to promote COI biodegradation can lead to
aquifer acidification;
• Facilitates Natural Attenuation Processes. For all the reasons summarized above,
EHC enhances the natural biological processes. Other technologies may offer short

term COI reduction via sorption reactions, etc. but they can alter the environmental
conditions such that natural attenuation mechanisms are adversely influenced; and
■ Simultaneous Immobilization of Heavy Metals. EHC will not mobilize arsenic, and
EHC-M will simultaneously immobilize many other heavy metals, which may be
present as other potential CO Is.
UNDERSTANDING SITE CONDITIONS AND GOALS
Site soil and groundwater is impacted by CVOCs. The primary constituent of concern is PCE,
which has been measured at a maximum concentration of 13 mg/kg in soil and 1.5 mg/L in
groundwater. For this remedial measure, the goal is to treat the on site portion of the plume.
Figure 5 shows concentrations in groundwater measured in April 2008. The groundwater
table is at ca 14.5 ft bgs and the linear groundwater velocity has been estimated at ca 20
ft/year. The lithology is composed of clay overlying saprolite, which is encountered at ca 20 ft
bgs (Figure 6). The plume extends into the saprolite and shallow bedrock, however, the
groundwater mixing zone has been estimated to extend from the groundwater table down to
the bedrock (estimated average treatment thickness of 24 ft). Total porosity is 58.6%.
Current redox conditions appears to be hypoxic, with only lower levels of D❑ and nitrate and
an ORP of less than 100 mV (Table 1). The aquifer is slightly acidic which can be
predictably problematic for carbon -only amendments.

REMEDIAL DESIGN
The goal is to create a permeable reactive barrier (PRB) across the plume area for passive
plume treatment over time. The groundwater will be treated as it flows through the PRB and
an area downgradient from the treatment barrier will be influenced via groundwater flow over
time. The extent of this zone will depend on the linear groundwater velocity; at a site in KS,
we have observed significant benefits at a distance > 600 ft downgradient of the PRB within
a 3 year period (Appendix A). The EHC PRBs will have to be rejuvenated every 4 to 6 years
for the life of the source. A design with several PRB units could also be considered for
complete plume clean-up over time; the spacing and number of barriers could be varied
depending on your clean-up timeframe and linear groundwater velocity. For pilot testing of
this approach, we recommend installing a PRB segment directly upgradient of the source
area well MW-3.
For the purpose of this cost estimate we have assumed a PRB dimension of 100 ft long x 20
ft wide x 24 ft deep (from 14 to 38 ft bgs). The PRB unit will be composed of two lines of
injection points spaced 10 ft apart. The injection points will be spaced 10 ft on center within
the lines and the lines will be off -set by 5 ft, resulting in an effective spacing of 5 ft

perpendicular to flow (to yield some overlap). To sustain continuous treatment over time, an
application rate of 0.5% to soil mass will be applied within the PRBs. This result in a total of
15,500 Ibs of EHC required for a 100-ft long PRB unit.
The EHC will be provided in 50 lb bags as a dry powder and mixed with water on site into an
aqueous slurry containing 20 to 30% solids. The EHC slurry will be injected into the ground
using high-pressure direct injection techniques. PLEASE NOTE that the below construction
estimates presented below can be readily modified in the field as required (for example, the
density of the slurry can be changed to modify the total injection volume or the injections
spacing could be altered based in installation technology).
Adventus' costs for one PRB unit are presented in Table 2. These costs include EHC plus
delivery (estimated). Adventus on -site field support for the initiation of the project is
presented as a recommended option. This cost does not include remedial construction or
services assigned to ATC. These costs are valid for 45 days.

DISTRIBUTION OF RESPONSIBILITIES
For field scale work at the Site, Adventus will provide environmental biotechnology and
design support. It is our intention and understanding that ATC will be responsible for
remedial construction, permitting, performance monitoring and reporting. The distribution of
responsibilities envisioned is as follows:
1. Adventus will provide and arrange delivery of EHC to the Site.
2. ATC will be responsible for remedial construction contracting.
3. It is highly recommended that Adventus personnel be on site during project start-up to
support ATC's field staff.
4. Adventus will provide data interpretation to ATC upon request.
5. Adventus will provide technical writing support to ATC, upon request.
G. ATC will provide manpower for receiving shipments, monitoring treatment
performance and collecting samples.

R. ATC will be responsible for all health and safety, permitting and approvals, sampling
and analytical costs along with all data management and reporting costs.
Adventus will provide copies of our patents and written, full indemnification hacked by
insurance coverage to ATC and the end -user 1 client from any lawsuits purporting
patent infringement or other technology violations.
Adventus warrants the performance of its technology. In the event that the prescribed
EHC injections do not yield at least 80% reduction in overall COI groundwater concentrations
within the treatment zone within 9 to 12 months, then we will provide an equivalent amount of
EHC at 50% of the listed price (plus delivery costs). Adventus' field installation oversight
would also be provided at no cost. This performance guarantee requires that a
representative from Adventus is on site for the initiation of the project and that the injections
are conducted according with Adventus' recommendations.
On behalf of Adventus, I thank you for your interest in our products and technologies. Please

EHC. Pilot Study for Oregon DEQ's Dry Cleaner Program at a Former Dry Cleaner Site, OREGON USA
Project manager/regulatory contact: Don Hanson, Oregon Department of Environmental Quality
Sttmmary
Groundwater at the former Serry's dry cleaner site in Corvallis, Oregon, was impacted with chlorinated volatile
organic compounds (CVOCs). The key CVOCs found at the site include PCE, TCE, DCE, and VC, as high as
22,000, 1,700, 3,100, and 7 ppb, respectively. Field scale pilot tests were performed for the Oregon DEQ's Dry
Cleaner Program to evaluate the performance of EHC*, an in situ integrated biological and chemical reduction
(ISCR) technology. The method of injection was also evaluated to determine the effectiveness of the injection
method in distributing EHC, given the low permeability of soils at the site (sandy silt and silty clay). Subsequent
field monitoring has shown greater than 99.9% removal of total CVOC concentrations two years after the
injections, without the accumulation ofcatabolites or rebound of CVOCs.
The Challenge
The groundwater flow direction at the site changes with seasonal conditions, and is either toward the south-east or
the north-west. The groundwater velocity is unknown, but assumed to be low due to the type of soils at the site. No
confirmed source of PCE has been found, however groundwater concentrations suggest that there may be two hot
spots on site: the north-west corner and south-east corner of the building. The building is currently occupied and
access is difficult to obtain. The primary goal of the pilot -scale treatment is to reduce groundwater concentrations at
the southeastern hot -spot that may have historically contributed to indoor air vapor intrusion at nearby residences.
Test Injection
A test injection was conducted prior to full-scale implementation to evaluate the effectiveness of direct push
methods in distributing EHC in the low permeability soils. A total of 450 lbs of EHC was injected from 13 to 25 ft
bgs (4 discrete layers, spaced 4 ft apart) using GeoProbe's pressure activated injection tip. A high pressure
pneumatic grout mixing and pumping system was used to mix and pump the EHC to the injection tip. Six soil
cores were obtained around the injection point (from 0.5 to 5 ft from the injection point) to assess the radius of
influence of the injection (Figure 1). EHC fractures were found at the farthest sampling points indicating that the
radius of influence was up to at least 5 ft. Figure 2, 3, 4 and 5 show some of the EHC bands or fractures observed
in the soil cores.
The following lithology was observed from the soil sampling:
■ Brown sandy, clayey silt from S to 20 ft bgs;
■ Stiff brown silty clay from 20 to 22 ft bgs;
• Stiff gray clay below 22 ft bgs;
• Water bearing and loose sand layers were encountered at
approximately 26 ft bgs.

Field -Scale Pilot Study
In August 2006, a total of 10,250 Ibs of
EHC was injected into an area measuring
approximately 825 112 x 20 ft deep (from
10 to 30 ft bgs), which resulted in an
average application rate of 0.6% to soil
mass. The EHC was supplied as a dry
powder in 50-lb bags and mixed with
water on site into slurry containing about
29% solids (Figure 6). Using conventional
direct push technology, the EHC slurry
was injected at 3 to 6 GPM at a pressure of
approximately 200-400 psi. The depth
interval targeted was from the groundwater
table (ca. 10 tt bgs) to approximately 30 ft
bgs, where a less permeable layer was
encountered. The EHC was injected in
discrete layers using the Geoprobe
pressure -activated injection tip and high
pressure grout mixing unit.

pressure build-up in the subsurface. The
treatment area was therefore increased
resulting in a lower application rate of 0.6%

addition, a relatively tight injection spacing
of 5 ft was used for the EHC injections

The Result
Following injection of EHC into the suspected source area, PCE was decreased to below the detection limit of 1
ug/L and total CVOCs decreased from a maximum of 25,606 ug/L to below 100 uglL at all locations within 12
months (Figure 8). The PCE degradation resulted in an initial build-up of TCE, DCE (primarily cis-DCE) and VC,
indicating that sequential dehalogenation was occurring (biological pathway). However, conversion rates were less
than Stoichiometric and concentrations of all constituents appeared to decrease simultaneously, suggesting that
abiotic treatment mechanisms also occurred at significant rates. Observed generation of VC was limited, indicating
that abiotic beta -elimination was a primary pathway for cis-DCE degradation. A smaller concentration of
chloroethane (CA) was also observed (maximum concentration of 44 ug/L measured in February 2008 — 18-month
data), suggesting that hydrogenation of VC might be occurring.

Flistorically, CVOC concentrations in groundwater fluctuate heavily with the seasons in the study area. )Figure 9
shows the groundwater elevation and total CVOCs concentrations measured since the well installations. Transient
rebound was observed during the rainy season
(18-month data), presumably due to the
introduction of CVOCs from the smear zone as
a result of a 6 to 7 ft (1.8 to 2.1 m) increase in
the groundwater table. While the groundwater
table remained high through June 2008 (22-
month data), total CVOC concentrations
decreased, suggesting continued treatment via
resident, active EHC. By August 2008 (dry
season), PCE and TCE both decreased to below
the detection limit of 1 ppb at all locations. The
rebound observed during the following wet
season (March 2009) was much smaller than the
previous year, suggesting that treatment of the
smear zone is being achieved as desorption is
promoted. Figure 9: Total CVOCs and depth to groundwater.
Degradation end products. An increase in ethene and ethane levels confirms that complete degradation is
occurring (Figure 10); ethene levels of up to 760 ug/L were measured in July 2007 (11-month data) which

been achieved. TOC and Fe(II) has been measured at a maximum concentration of 2,800 and 130 mg/L

Redox indicator parameters: Following the EHC injections, the oxidation-reduction potential (ORP)
decreased within the injection zone. Sulfate concentrations decreased from a baseline concentration of 7 to
34 mg/L to below the detection limit of 4.1 mg/L, suggesting that sulfate reducing conditions was
established within the injection zone. Furthermore, an increase in methane suggests methanogenic
conditions and an excess amount of dissolved carbon. As dissolved carbon concentrations declined over
time, ORP has increased but remain below background levels. The fluctuations observed in ORP indicates
that the redox conditions may also be affected by the shifts in the groundwater table, with generally more
reducing conditions during the rainy season.

Project - Co -Treatment of TCE and Chromium using EHC-Mo
Manufacturing Facility, Washington
Lead Consultant - EA Engineering, Science, and Technology, Inc.
Summary
EHC-M* has been shown to effectively treat ca. 6.1 ppb trichloroethene (TCE) and
immobilize ca. 165 ppb hexavalent chromium (Cr(Vl)*) from groundwater at a
manufacturing facility in Washington. Following the injection of EHC-M performed
in September 2006, subsequent performance monitoring conducted in October 2006
and January, May, July and October 2007 showed TCE and all related daughter
products below the detection limit of 0.05 ppb. Cr(VI) was reduced by >90% to 11
ppb one month following the injections and has remained below the detection limit
of 5 ppb since the January 2007 sampling event.
The Challenge
Field Profile
EHC-M�
The site soil and groundwater is impacted with TCE and elevated levels of Cr (VI). An extraction system is
currently in operation at the site, which has cleaned up portions of the downgradient end of the plume to below the
treatment goals of 5 ppb for TCE and 80 ppb for Cr(VI). However, an isolated area experienced rebound when the
extraction system was not operated and it appeared that the extraction system was not effective for treatment of the
source of this rebound. A concentration of 6.1 ppb TCE and 165 ppb Cr(VI) was measured at the former extraction
well MW-41 in April 2006 (Figure 1). The conditions were relatively oxic with a ❑O of 5 mg/L and ORP of 200
mV. The goal was to clean up this isolated hot -spot area to allow for the extraction system to be shut down
completely at the downgradient end of the plume, which would result in significant cost and energy savings.

The Solution
In September 2006, EHC-M was injected
into the suspected hot -spot area upgradient
of extraction well M W-4l. The targeted
treatment area measured an estimated 50 ft
wide x 100 ft long x 10 ft deep (from 75 to
85 ft bgs). A total of 9,600 Ibs of EHC-M
was injected into the area, resulting in an
average application rate of 0.15% to soil
mass. The application rate applied was
higher than the concentrations of TCE and
Cr(VI) would suggest given the relatively
oxic conditions at the site. The EHC-M was
injected as a slurry using direct injection.
The injection points were spaced 10 to 15 ft
apart, which resulted in a total of 32
injection points (Figure 2).

The Result
Subsequent performance monitoring conducted in October 2006 and January, May, July and October 2007
showed TCE below the detection limit at the former extraction well MW-41 (Figure 5). Cr(VI) was reduced by
>90% to 1 l ppb one month following the injections. Four months following the injections of EHC-M, Cr(IV) in
groundwater had been reduced to below the detection limit of 5 ppb. Subsequent monitoring has shown that the
chromium remained immobilized. An additional monitoring well, AMW-63, was installed in November 2006 at the
center of the injection zone. TCE was non -detect and Cr was measured at 9.5 ppb at this new well in January 2007.
TCE has remained below the detection limit of 0.05 ppb since July 2007, whereas total Cr was measured at 6.3 ppb
in the latest monitoring event conducted in October 2007. All related daughter products from TCE degradation (cis-

2005 DEPARTMENT OF THE NAVY SUCCESS STORY — CANDIDATE FOR
CONGRESSIONAL BRIEFING
Project
Enhanced Reductive Dechlorination (ERD) and In Situ Integrated Biological and Chemical Reduction (ISCR) using
EHC*, CH2M Hill, U.S. Marine Corps Site, North Carolina
Summary
Site groundwater was impacted with chlorinated volatile organic compounds (CVOCs) at concentrations as high as
80,000 ppb. A total of 24,100 lbs (10,955 kg) of EHC was injected into areas of elevated CVDCs concentration to
yield enhanced ISCR. Six months after the EHC injection, TCA levels had decreased by 94% and TCE levels had
decreased by 84 to 90% at the targeted areas, without generation of problematic catabolites.
The Challenge
The surficial aquifer consists of unconsolidated, inter -lingering beds of fine sand, silt, clay, shell, and peat beds
with scattered deposits of coarser grained material as part of relic beach ridges and alluvium. The aquifer averages
about 40 ft (12 m) thick and has an estimated average hydraulic conductivity of 10 ft/day (3 mlday). Site
groundwater under a sensitive operational facility was impacted by TCE, cis 1,2-DCE, 1,1,1-TCA and 1,1-DCA
with maximum detected concentrations of 73,000, 6,600, 24,000 and 4,800 ppb, respectively. These impacts
extended from about 10 ft (3 m) bgs to a depth of approximately 20 ft (6 m) bgs. The goal was to reduce the
CVDCs mass in a timely and effective manner.
The Solution
There were two hot spot areas on site targeted for remediation; these were located under Buildings "A" and "B". In
January 2005, a total of 24,100 lbs (10,955 kg) of EHC were injected into the two hot spot areas. Approximately
13,400 1bs (9,091 kg) of EHC were injected at Building A into an area measuring approximately 1 10 ft (34 m) long
x 150 ft (46 m) wide x 10 ft (3 m) deep, giving an EHC application rate of approximately 0.07% to soil mass.
Approximately 10,700 lbs (4,864 kg) of EHC were injected at Building B into an area measuring approximately
100 ft (30 m) long x 150 ft (46 m) wide x 10 R (3 m) deep, giving an EHC application rate of approximately 0.06%
to soil mass.
The EHC was supplied as a dry powder in 50-lb (23 kg) bags and mixed with water on site into slurry. The EHC
slurry was injected into a total of 47 injection locations from 10 to 20 ft (3 to 6 m) bgs. The injections were
conducted using a direct injection technique and the injection points were spaced approximately 25 R (7.6 m) apart.
Figures I and 2 show the injection layout at Buildings A and B, respectively.

The Result
Figures 3 and 4 shows the concentration of CVOCs in groundwater at the hottest well at Building A and Building
B, respectively, before and after the EHC injection. As summarized below, EHC treatment effectively removed
CVOCs without the accumulation of catabolic intermediates.
TCA: Six months following the EHC injection, rigorous performance monitoring showed that TCA levels
decreased by 94% (from 24,000 to 1,400 ppb) at the hottest area at Building B, without accumulation of
problematic catabolites. TCA levels remained non -detect at Building A.
TCE: Six months following the EHC injection, TCE levels decreased by 91 % (from 49,000 to 4,400 ppb) at
Building A, with a slight increase in DCE levels (from 3,027 to 5,819 ppb). TCE levels decreased by 84% (from
7.400 to 1.200 nt)b) and total DCE levels decreased by 72% (from 5,300 to 1,488 ppb) at Building B.

Project
EHC* Treatment of{rroun& ater flume Containing Chlorinated Solvents, Confidential Client - SE USA
The Challenge
Groundwater at a former manufacturing facility was impacted by chlorinated solvents, primarily carbon
tetrachloride (CT) and trichloroethylene (TCE), as well as organochlorinated pesticides (OCPs). Adventus
employed its EHC in situ integrated biological and chemical reduction (1SCR) technology yielding safe, rapid and
effective in situ treatment. After only 3 months of EHC application, the CT concentration decreased from 260 ppb
to 7.8 ppb (97% removal) without the accumulation of catabolic intermediates. Treatment improved further at the
6-month sampling, showing a removal to 0.8 ppb (99.7% removal). All six of six monitoring wells met the
groundwater clean up criteria for volatile organic compounds (VOCs).
The Solution
EHC* is a patented combination of controlled -release carbon and zero valent iron (ZVI) particles used for
stimulating reductive dechlorination of otherwise persistent organic compounds in groundwater. The volume
requiring treatment was 110 ft (34 m) wide by approximately 190 ft (58 m) long, from 15 to 40 R (4.6 to 12 m)
below ground surface (bgs). The approach was to create three, I0 ft (3 m) wide reactive zones: one at the
upgradient edge, and two in the middle of the treatment area. The theory behind this approach is that the volatile
fatty acids, hydrogen, and ferrous iron released from EHC would migrate downgradient to treat the plume. Further,
contact between contaminants and the ZVi that is incorporated in the EHC product would be chemically treated. A
total of 45,000 lbs (20,455 kg) of EHC were applied at the site. Within the reactive zones, the application rate was
0.5% by dry soil mass; however, the overall application rate for the total area treated was 0.08%.
The injections were completed in June of 2005 using direct injection (Figure 1). The first round of monitoring well
sampling occurred in September of2005.

Project Update Jan 2010
Grain Silo Facility, Kansas
Lead Consultant - Malcolm Pimie, Inc.
Summary
EHCtL has been shown to effectively treat carbon tetrachloride (CT)
and its catabolites. A large-scale field effort was undertaken to: i)
validate EHC performance under field conditions, and ii) assess the
effectiveness of the construction methodology (i.e., direct injection of
EHC slurry). 24 tons of EHC were injected into a 270 ft (83 m) long
permeable reactive barrier (PRB) intersecting the groundwater plume
downgradient of the suspected source area. Subsequent field
monitoring showed a 76% and 88% decrease in CT concentrations
after just 4 months, without the accumulation of recognized
catabolites, such as chloroform (CF). Continued monitoring has
shown that the PRB has remained active for over 48 months and that
the decreasing trend in CT concentrations has migrated a significant
distance downgradient from the PRB with a 99.5% decline in CT
observed 70 ft (21 m) from the PRB and a 91% decline observed 600
ft (183 m) from the PRB.
The Challenge
Site groundwater is impacted with CT at concentrations of up to 2,700 ppb. The CT plume extends approximately
2,500 ft (760 m) from a grain elevator where it discharges into a small creek (Figure 1). The remedial goal is to
treat CT to <5 ppb, CF to < I00 ppb, Chloromethane (CM) to < 20 ppb and methylene chloride (MC) to <5 ppb. The
CT source area is elusive, but impacts are likely the result of using CT as a fumigant in the grain silos on the site.
There is a complex geologic history in the study area which resulted in a mix of interbedded sand, gravel, clay and
silt. Two primary saturated sand units have been
identified, named as the upper and lower saturated
sand units. The upper sand unit is approximately 3 to
4 ft (0.9 to 1.2 m) thick. The thickness of the lower
sand unit varies considerably across the site and
ranges from 0 to 13 ft (0 to 4 m) thick. The
groundwater table is encountered at approximately 23
ft (7 m) bgs at the PRB area; CT impacts extend down
to a maximum of approximately 45 R (14 m) bgs. The
bedrock rises to an elevation approximately 10 feet (3
meters) above the present day water table at the
presumed source area. The CT is believed to have
transported along the topography of the bedrock
surface to the downgradient aquifer. Access
restrictions due to residential properties further
complicates source area clean-up.

In March 2005, a total of 48,000 lbs (21,818 kg) of EHC were injected into a 270 ft (83 m) long PRB across the
plume. The EHC was applied at a rate of approximately 1% to soil mass into the upper and lower saturated sand
units. The EHC was supplied as a dry powder in 50-lb (23 kg) bags and mixed with water (Figures 2 and 3) on site
into slurry containing about 40% solids. The EHC slurry was injected into twenty-seven injection groups composed
of 126 injection borings using a direct injection technique. Injection borings targeted a specific depth in either the
upper or lower saturated sand unit. Each injection group was spaced 10 ft (3 m) apart. This injection approach was
employed to avoid injecting the majority of EHC slurry into the bottom intervals.

The Result
Figure 6 shows the concentration of CT and daughter products in groundwater measured upgradient and
downgradient of the EHC PRB. The downgradient monitoring wells are located 70 ft (21 m), 140 ft. (43 m) and 600
ft (183 m) downgradient of the PRB, which equals approximately 39, 78 and 333 days in terms of groundwater
travel time. Groundwater sampling results as early as four months after installation of the PRB showed a 76% and
88% decline in CT concentration at monitoring wells located 70 and 140 ft (21 and 43 m) downgradient of the PRB,
respectively. Groundwater sampling results 13 to 36 months after installation of the PRB have shown a >940/0
decline in CT concentration at the core of the plume 70 ft (21 m) downgradient of the PRB. CF concentrations
initially increased as a result of the CT degradation. However, by February 2007 CF had decreased to 8.4 ppb,
which is below background and initial concentrations. DCM and CM has remained below the detection limits in
both the inflowing and downgradient wells since the May 2006 monitoring event. The edge of the plume retrains
non -detect (100% removal) for all analytes since August 2005. At the five most recent sampling events conducted
in February and August 2007, April and October 2008 and April 2009, affects of the PRB were observed 600 ft

initial concentration of 140 to 13 ppb} and again, no accumulation of catabolites. Meanwhile, inflowing
concentrations have fluctuated with a high of 2,700 ppb measured in February 2007.

acclimatization occurred, but has slowly decreased since reaching its peak value of 1.3 days after 17 months, which
is likely due to consumption of the EHC amendment. CF concentrations initially were detected as a result of the CT

The material cost of using EHC was $371ft' ($395Imx) of PRB cross-section (270 ft long x 9.7 ft deep on average).
Using an estimated linear groundwater velocity of 1.8 ft/day (1.6 to 2.2 ft/day estimated) and a porosity of 30%, the
PRB is treating an estimated total of 516,000 ft' (14,600 m') of groundwater per year (270 ft long x 9.7 ft average
depth x 365 days x 1.8 ft/day x 30%). With an estimated life of at least 5 years, the PRB is expected to treat a total
of 2,580,000 ft3 (73,000 m) of groundwater during its life -time at a product cost of $0.04/ft3 ($1.321m').
Furthermore, continued monitoring is expected to show that ERDIISCR using the EHC technology offers a safe,
effective and cost-efficient remedial solution for similarly impacted environments. The reactive zone constitutes a
green solution (n❑ energy requirements) and maintenance costs are limited to groundwater monitoring over the life
of the PRB. Based on observed decline in degradation rates, PRB rejuvenation requirements are estimated after 4 to
5 years.
Conclusions
Removal Efficiency: Groundwater sampling results have shown up to 99.5% decline in CT concentration at the
core of the plume 70 R downgradient of the PRB (from an initial concentration of 1,000 ppb to 5 ppb measured in
August 2006), without accumulation of catabolites.
Longevity: A single application of EHC has remained active for a period of >4 years, continuously supporting
>94% removal of CT, without the accumulation of catabolites.
Plume Impacts: The reactive zone has had significant impacts on the extent of the CT plume. In the last 5
sampling events conducted 22 to 48 months after the EHC injections, effects of the PRB has been observed 600 ft
(183 m) downgradient from the PRB, with a 91 % decline in CT concentrations measured in April 2008.

Project Update June 2009
Former Unregulated Solid Waste Management Unit, Ohio
Lead Consultant— Hull & Associates, Inc.
Summary
Groundwater at a former unregulated solid waste management unit is impacted by various chlorinated volatile
organic compounds (CVOCs), mainly chlorinated ethenes. Groundwater collection trenches totaling approximately
330 ft in length were previously constructed downgradient of the suspected source areas. In February 2006, EHC
was injected into the gravel trenches to convert them into permeable reactive barriers (PRBs). A microbial culture
of Dehalacoccoides species (KB-1 inoculant; SiREM) was also applied to the main trench. Subsequent field
monitoring showed that trichloroethene (TCE) and cis-1,2-dichloroethene (cis-DCE) decreased below the detection
limit within the trenches after just 6 months, without the accumulation of recognized catabolites, such as vinyl
chloride (VC}. Continued monitoring has shown that the PRBs remain active for over 3 years and that the
concentration of total chioroethenes is decreasing downgradient of the center of the PRB (over 97% removal since
November 2006). A positive correlation between the presence of EHC breakdown products (TOC and dissolved
Fe), Dehalacoccoides count and removal rates has been observed downgradient of the PRB.
The Challenge
Site groundwater proximal to a known area is impacted by
TCE (maximum of 750 ppb; remedial objective = 5 ppb) and
its recognized anaerobic daughter products 1,2-DCE
(maximum of 5,200 ppb; remedial objective = 70 ppb) and
VC (maximum of 630 ppb; remedial objective = 2 ppb). In
an effort to mitigate transport of groundwater CVOCs,
collection trenches measuring approximately 250 ft long
were previously installed along the southern and western
boundaries of the former unregulated solid waste
management unit. Another collection trench measuring
approximately 80 ft long was installed inside of a building
(Figure 1 — red lines). The goal of this current project was to
turn these existing collection trenches into permeable
reactive barriers (PRBs) to passively treat the groundwater
as it flowed through the newly created reactive treatment
zones. The groundwater table is generally at 6 ft below
ground surface (bgs) and the trench extends down to
approximately 12 ft bgs. The trenches measures 2 ft wide
and are filled with washed river gravel up to a foot above the
groundwater table.

consisted of solid organic carbon and zero-valent iron at 42%. The EHC powder was mixed with water on site into
a slurry containing approximately 20 to 25 percent solids using a grout mixer. The injection points were spaced 10
ft apart, resulting in a total of 30 injection points. A total of 400 lbs of EHC (ca 200 USG of slurry) was designed

along the property line to accelerate removal of cis-1,2-dichlorethylene DCE. No inoculants were added at the
trench inside the building.

Monitoring Program
Following the installation of the EHC
PRB, the groundwater was sampled for
CVOCs on a quarterly basis at the
following locations (Figure 4):
-Manholes (CB-1 and CB-2),
- Downgradient wells (MK-5 and
M K-6),
- Sidegradient well (MK-7), and
- Downgradient piezometer (P5).
In addition, groundwater quality field
parameters including pH, DO,
temperature, water level and ORP have
been collected monthly. Nine months
following the installation of the PRBs,
the groundwater was analyzed for total
iron, ferrous iron and TOC to verify
which sampling locations are within the
EHC zone of influence. Samples from
MK-5, MK-6 and P5 were also analyzed
for Dehalococcoides species.

The Result
Figures 5 and 6 shows the concentration of total chloroethenes in groundwater collected from the collection
manholes at the downgradient end of the trenches. The first round of performance monitoring (May 2006) was
conducted approximately three months after the EHC injections and did not show any discernible response.
However, subsequent monitoring conducted over a three year period post EHC injection showed almost complete
removal of all CVDCs, without the accumulation of catabolites. In the latest monitoring event, conducted in
February 2009, total CVOCs decreased by >99.9% at the trench along the property line (from 2,700 to l ppb) and
99.5% at the building trench (from 1,950 to 9 ppb) compared to the initial concentrations measured in September,
2004.

had decreased by 99.7%; TCE decreased from 370 ppb to ND (<I ppb), DCE from 2,800 to 4.5 ppb, and VC from
510 ppb to 4.8 ppb. Subsequent measured removal rates have remained between 96.6 and 99.0% for over 3 years of

No consistent CVOC removal has been observed in the other monitoring locations outside of the trench (MK-6 and
P5). To verify whether these points were within the direct zone of influence of the EHC, the groundwater was
sampled for TOC and total and ferrous iron nine months following the injections. Following the injection of EHC
into the subsurface a significant increase would be expected in these parameters within and directly downgradient
of the injection zone. The extent of the zone with elevated levels of EHC breakdown products will depend on the
linear groundwater velocity and direction.
Elevated levels of TOC and iron were
measured within the trenches and at MK-
6, directly downgradient from the lowest
point of the trench which correlates with
the CVOC removal achieved at these
locations. No significant increase of EHC
breakdown products was observed at the
remaining sampling locations and it could
therefore be assumed that the EHC PRB
has not directly impacted those locations
yet. This could possibly be explained by
the flaw -pattern created by the gravel
trenches installed into the low -
permeability clayey soil; the groundwater
would be expected to be directed through
the gravel collection trenches (as
designed) and to be primarily released at
the lowest point by collection manhole
CB-1. This would also be supported by
the significant and fast removal of
CVOCs at MK-6 directly downgradient
from manhole CB-1 (Figure 8).

Project
Installation of EHCTM for Treatment of Chlorinated Volatile Organic Compounds, Site in Texas
Summary
Adventus installed 1 ton (909 kg) of EHC into a trench and 3 tons (2,730 kg) of EHC into an open
excavation at a site that has groundwater contaminated with a mixture of chlorinated solvents.
The Challenge
Two areas of contamination were targeted for treatment. The first was a dissolved plume migrating from a
source zone through a thin permeable soil unit overlying bedrock at approximately 12 ft (3.7 m) below
ground surface. The second was an open excavation containing groundwater, after contaminated soil had
been removed. The client's site was contaminated with a large range of Contaminants of Concern (COCs)
at the two locations (Table 1).

The Solution
To treat these contaminants, EHC was selected for in situ treatment of the contaminants. Adventus
recently adapted its patented combination of controlled -release solid carbon and zero vaient iron (ZVI)
particles to yield EHC, a solid material for stimulating reductive dechlorination of otherwise persistent
organic compounds in groundwater. Following placement of EHC into the subsurface, a number of
physical, chemical and microbiological processes combine to create strong reducing conditions that
stimulate rapid and complete dechlorination of organic solvents and other persistent compounds.
A permeable reactive barrier (PRB) was constructed to intercept the dissolved groundwater plume
(Figure 1). The PRB was constructed with an excavator by digging a 3 ft (0.9 m) wide trench down to the

top of the bedrock, followed by filling the bottom foot with a mixture of EHC and sand (Figure 2). Only
the bottom foot required filling because the groundwater table was less than a foot above the bedrock, and
the permeable soil unit was also at this depth. The remainder of the PRB was backfilied with pea gravel.
Figure 1:
d
Backfilling of PRB with pea gravel.
Figure 2: EHC and sand mixture used
to fill trench and excavation.
The bottom 1 ft (0.3 m) of the excavation was lined with sand and EHC (Figure 3), and the downgradient
wall of the excavation was lined with a 3 ft (0.9 m) high, 3 ft (0.9 m) wide bench of sand and EHCTM. The
3 ft (0.9 m) high bench would ensure that any water exiting the excavation at the downgradient side
would come into contact with the sand and EHC mixture.

The installation was completed in early 2004. To monitor effectiveness of the installation, wells were
placed upgradient and downgradient of the OPRB as well as within and downgradient of the excavation.
Figure 4 shows results at the excavation (shows complete VCC removal from the source area).
Two pairs of upgradient and downgradient monitoring wells are being used to evaluate the effectiveness
of the PRB for treatment of the dissolved plume. The data for the first upgradient-downgradient pair are
provided in Figure 5, with the upgradient data on the left-hand side, and the downgradient data on the
right-hand side. Large reductions of all of the constituents present continue to be observed after 21
months of field data. Data for the second well pairing are shown in Figure 6, with lower Overall

Project
EHCTm Treatment of Chlorinated Ethenes, Ethanes, and Methanes in Saprolite Soils and Partially
Weathered Rock, Manufacturing Facility — Western NC
Summary
Field scale pilot tests were performed to evaluate the performance of enhanced reductive dechlorination
(ERD) of chlorinated aliphatic hydrocarbons (CAHs) at a manufacturing facility in western North
Carolina. The key CAHs found in groundwater at the site include 1,1,2,2 tetrachloroethane (TeCA),
trichloroethene (TCE), and chloroform (CF), as high as 350, 1,100, and 1,500 ppb respectively. Adventus
employed its EHC in situ integrated biological and chemical reduction (ISCR) technology yielding safe,
rapid, and effective treatment. Eleven weeks after injection, concentrations of TeCA, TCE, and CF in a
nearby well reduced by 86%❑, 98%❑ and fife%❑, respectively. After approximately 26 months, the key CAHs
in the monitoring wells in the silty -clay (saprolite) zone indicated an overall decrease of up to 95%❑.
The Challenge
The site is located in the Appalachian Piedmont physiographic province (mountainous) of North Carolina
and consists of saprolite soils overlying a partially weathered rock (PWR) zone. Fractured bedrock
underlies the PWR zone. Groundwater concentrations have rebounded since historical treatment,
indicating the potential for continuing sources, desorption, or problematic hydrogeology or microbial
conditions at the site. Presence of low permeability soils, low groundwater velocities and a mixture of
CAHs presented a unique challenge for remediation.
The Solution
EHCTm is a patented combination of controlled -release
carbon and zero valent iron (ZVI) particles used for
stimulating reductive dechlorination of otherwise
persistent organic compounds in groundwater. Two
pilot -scale permeable reactive barriers (PRBs) were
installed in January 2005 to evaluate the efficacy of EHC
to control and treat the chlorinated solvents plume in two
areas of the site. The first injection PRB was installed
into the saprolite between 10 and 25 ft below ground
surface (bgs) and the second injection PRB was installed
into the partially weathered rock (PWR) between
approximately 30 and 35 ft bgs. Each PRB measured an
estimated 40 ft long x 20 ft wide. Approximately 3,000
pounds of EHC was injected in two Geoprobe boreholes
in the saprolite zone and 3,500 pounds of EHC was
injected at four drilled locations in the PWR zone.

ADVENTUS Project Description
The presence of low permeability soils and the PWR zone required hydraulic fracturing to inject EHC at
the site. Injection pressures and ground uplift were monitored, and soil boring and monitoring wells were
installed to verify fracture propagation and distribution of the EHC. Soil samples collected around the
injection points indicated the presence of EHC material. Based on field observations, the influence of
EHC injection extended in a zone approximately 10 to 15 feet around the injection point in the saprolite.
The injection in the PWR zone was controlled by the fracture orientation.
The presence of high concentrations of total organic carbon and metabolic acids and negative oxidation-
reduction potential in the nearby monitoring wells indicated that the injected EHC created anaerobic
zones favorable for CAH reduction.
The Result
Eleven weeks after injection, concentrations of TeCA, TCE, and CF in a nearby well in the PWR zone
reduced by 86%, 98% and 66%, respectively. After approximately 26 months, these compounds in the
same well reduced over 98%. Potential degradation products of these CAHs such as 1,1,2-
trichloroethane, methylene chloride, cis-1,2-dichloroethene, trans-1,2-dichloroethene, vinyl chloride,
ethene, ethane and methane were detected in low concentrations, as shown in Figure 3. The
concentrations of TeCA, TCE and CF initially increased in one downgradient well in the saprolite zone
and gradually decreased. The test results indicated that reductive dechlorination was delayed in the

aquifer despite the presence of dechlorinating bacteria such as Dehalococcoides, Dehalobacter and
Methanogens. The likely reasons for the slow treatment response are the slow rate of groundwater flow
as well as desorption of CAHs. After approximately 26 months, the key CAHs in the monitoring wells in
the saprolite and PWR zone indicated a decrease of up to 99% (see Figures 1, 2, and 3). Despite the
reductions in CAH concentrations, organic carbon is still present supporting the reductive dechlorination
process in the saprolite and PWR zone.

0EHCTM Installation Procedures
� AI�VENTL�S
6 Direct Injection
Introduction
EHCTm is the only in situ chemical reduction (ISCR) substrate available for removing persistent
organic and/or inorganic contaminants from the subsurface environment. EHC has been
employed for source area treatment, plume treatment or plume management using permeable
reactive barrier (PRBs). EHC slurry (10 to 45% solids) has been added to numerous aquifers
using a variety of injection methods, including hydraulic fracturing, pneumatic fracturing and
direct injection. Liquid formulations of EHC, EHC-A, have been added to existing well screens.
And solid EHC substrate has been directly mixed into the soil using deep soil mixing equipment
or placed into an open excavation or trench.
The choice of installation method will depend on your site -specific conditions, including
treatment depth and geology. To date, the most commonly practiced in situ application method
has been direct slurry injection. This document provides guidelines for preparation of the EHC
slurry and using direct injection technology for subsurface application.
EHCT"R Slurry Preparation
EHC is delivered as a dry powder in 50-lb bags or
2,000 lb Supersacks. EHC consists of solid organic
carbon and zero-valent iron and will be mixed with
water on site into a slurry containing an estimated 30%
solids (i.e., mass of dry EHC divided by total mass of
slurry including EHC and water). This results in a final
wet density of the slurry of approximately 1.15 g/cm3.
EHC slurry ->
Adventus recommends preparing the EHC
slurries on site in a mixing tank with a paddle -
mixer at the bottom. The slurry is then
transferred to a feed tank connected to the
injection pump; that way the slurry can be
prepared continuously while the injections are
performed. For example, the ChemGrout
mixing system with two mixing bins
(www.chemgrout.com/500hp.htm) has been
utilized. The EHC slurry mixes quickly in these
types of systems (about a minute) and the
injections can proceed without interruption.
F 2-bin mixing system
The EHC slurry has also been prepared in a variety of other ways; everything from in -line
automated mixing systems to manual mixing using a hand-held drill with a mixing attachment.
However, particularly for larger projects, Adventus recommends having a mechanical mixing
system available on site.

EHC'rm Injection Approach
The preferred approach for the injections is often in the
top -down direction using an injection tip that directs the
slurry horizontally, for example Geoprobe's pressure
activated tip has been successfully utilized
(http://www.geoprobe.com/products/geoprobe — accesso ri
eslinjprobedesc.htm). For each injection point, the rods
are initially advanced to the top of the targeted depth
interval and a specified volume of slurry is injected
before proceeding down to the next depth. The
injections are to be evenly distributed over the targeted
depth interval, using a vertical injection spacing of
approximately 2-4 ft. We recommend injecting a small
volume of water (15 USG) to clear the injection tip
between batches and at the end of the injection.
Pump Requirements
Test of pressure activated tip
with 4 horizontal openings.
Adventus recommends using an injection pump that is capable of generating at least 300 psi of
pressure at a flow rate of 5 gpm. The pump needs to be able to handle solids. For example
piston pumps, grout pumps and progressing cavity pumps have worked well in the past, with a
preference towards the piston and grout pumps. EHC would typically be injected at pressures of
100 to 200 psi, however, higher pressures are sometimes required to initiate the injection. It.
would be ideal to have a higher pressure pump available on site that can generate over 500 psi
and as high a flow rate as possible. Deeper installations may require higher injection pressures.
Other
We recommend having sufficient rod length and injection tips on site to allow 3 to 5 injection
points to be capped overnight to prevent backflow if need be (more for shallow depths and less
for deep installations).
Health and Safety
EHC is completely non -hazardous and safe to handle. The EHC MSDS is posted on our web
site at www.adventusgroup.com/library/msds.shtmi. When working with EHC, it is
recommended to use standard personal protective equipment, including safety glasses, steel
toe boots, nitrile gloves, hearing protection (when Geoprobe is operated) and hard hat. Dust
mask may be required when in close contact with EHC under certain conditions.

Permit No. WI0400131
In -Situ Groundwater Remediation Permit
Guilford County
Dear Ms. Olson,
ROY COOPER
Governor
MICI-IAEL S. REGAN
Secretary
LINDA CULPEPPER
Interim Director
Reference is made to your request for rescission of the subject permit located at the Former Cleaner A
World #162 Facility, Guilford NC. Staff from the Winston-Salem Regional Office has agreed that a permit
is no longer required. Therefore, in accordance with your request, In -Situ Groundwater Remediation Permit
W1400131 is rescinded, effective immediately.
If in the future, you wish to operate a In -Situ Groundwater Remediation system, you must first apply for
and receive a new permit. Operating an injection system without a valid permit may result in the assessment
of civil penalties and/or the use of other enforcement mechanisms available to the state.
If it would be helpful to discuss this matter further, please do not hesitate to call Shristi Shrestha at
[phone].
Sincerely,
U"�'Uj"zk

Genna
Just wanted to touch base with you concerning questions you recently received from Shristi Shresta, one of our UIC
permitters. She was asking about signature authority due to questions I was asking. I finally dug up Sulletin29 that
Thomas Slusser had sent me, along with guidance for DSGA sites, where it does state that project managers can sign
documents and not just officials as indicated in our rules. Since this was agreed to between DWSCA and DWR, we
will honor this. My apologies for any confusion this may have caused.

It's fine with me if she signs, but the applicant is the DSCA site petitioner and the power of attorney gives the DSCA
contractor the authority to sign as their agent. Meghan is the representative for the DSCA contractor, so I'm not sure
why she wouldn't be able to sign?

Thank for replying back. I will work on rescinding the permit. Our records show that there are 19 proposed wells
associated with the facility. Were the wells constructed? If they were then please submit construction records and

Hi Shristi,
Sorry for the delayed response. The email got buried in my inbox. The work associated with injection permit number
WI0400131 was never completed. As an agent for the petitioner for DSCA Site #DC410024, ATC would like to
rescind the permit that was issued. A limited power of attorney agreement is attached which allows ATC to act on
behalf of the petitioner for this site. Please let us know if you need any additional information. If any future work is
planned a new permit application will be submitted. Thanks'.

SUBSECT: Use of a Non -Biological Product EHC® by Adventus Remediation Technologies
to Enhance Biodegradation of Groundwater Contaminated with Chlorinated
Compounds at the BASF Technical Marketing Building Site in Enka, North
Carolina.
I am writing in response to a request for a health risk evaluation regarding the use
of use of a non -biological product EHCS, by Adventus Remediation Technologies, to
Enhance Biodegradation of Groundwater Contaminated with Chlorinated Compounds at
the BASF Technical Marketing Building Site in Enka, North Carolina. Based upon my
review of the information submitted, I offer the following health risk evaluation:
PRECAUTIONS DURING APPLICATION
Some effects or hazards reported to be associated with the chemical proposed for use are
as follows:
• Exposure can cause irritation of skin, eyes, nose, throat, and lungs (Medical
Management Micromedex TOM -Es Pius System CD-ROM Database, Volume 62,
2004)
2. If the products are released into the environment in a way that could result in a
suspension of fine solid or liquid particles (e.g., grinding, blending, vigorous shaking or
mixing), then it is imperative that proper personal protective equipment be used. The
application process should be reviewed by an industrial hygienist to ensure that the most
appropriate personal protective equipment is used.
Location: 2728 Caniml &rulcvarcl • Purker Lincoln Building • Itakcigh, N.C. 27604 An Equal Opportunity Employer

Persons working with this product should at least wear goggles or a face shield, gloves,
and protective clothing. Face and body protection should be used for anticipated splashes
or sprays. Again, consult with an industrial hygienist to ensure proper protection.
4. Eating, drinking, smoking, handling contact lenses, and applying cosmetics should never
be permitted in the application area during or immediately following application. Safety
controls should be in place to ensure that the check valve and the pressure delivery
systems are working properly.
5. The Material Safety Data Sheets should be followed to prevent adverse reactions and
injuries.
6. Access to the area of application should be limited to the workers applying the product.
In order to minimize exposure to unprotected individuals, measures should be taken to
prevent access to the area of application.
According to the information submitted, no public or private water supplies were
identified within a 1500-foot radius. Hominy Creek is less than 30 feet to the east of the
injection areas. The nearest residence is greater than 1500 feet from the injection area,
and the nearest workplace is the Buncombe County Offices at 300 feet from the injection
area. Both of these are located upgradient from the injection area. Efforts should be
made to prevent contamination of existing or future wells and nearby surface waters that
may be located near the application area.
Please do not hesitate to call me if you have any questions at [phone].
