AGREEMENT FOR PROFESSIONAL SERVICES
This Agreement For Professional Services (this "Agreement") is entered into on August
11, 2016 (the "Effective Date"), by and between the City of South Bend, Indiana, acting by and
through its Board of Public Works ("City"), and Hull & Associates, Inc., an Ohio corporation with
its registered office address at 6397 Emerald Parkway, Suite 200, Dublin, Ohio 43016 (the
"Provider") (each a "Party" and collectively the "Parties").
For and in consideration of the mutual covenants and promises contained herein, the Parties
agree as follows:
1. Services. The Provider will provide to the City the professional services set forth
in the Provider's proposal attached hereto as Exhibit A (the "Services"). In the event of any
conflict between the terms of this Agreement and the terms of Exhibit A, the terms of this
Agreement will prevail. The Provider will execute its obligations under this Agreement in
accordance with the prevailing professional standard of care ordinarily exercised under similar
conditions by reputable members of its profession practicing in the same or similar locality at the
time of service.
2. Compensation. In exchange for the Provider's satisfactory performance of the
Services, and subject to the terms and conditions of this Agreement, the City will pay the Provider
a total sum not to exceed Four Hundred Ninety -One Thousand One Hundred Sixty Dollars
($491,160) (the "Contract Amount"). The City will pay the Provider for services rendered upon
invoicing by the Provider in four -week increments (each a "Contract Payment"). The City will
not be required to make any Contract Payment if the City is not satisfied with the Provider's
performance under this Agreement or any default or breach of this Agreement by the Provider
exists, as the City may determine in its sole discretion. The sum of all Contract Payments will not
exceed the Contract Amount.

RE: Proposal to Implement a Groundwater Remedy; Conduct Quarterly Groundwater Sampling; and
Fulfill Regulatory Requirements at Oliver Industrial Park, South Bend, Indiana (the Site);
SBI074.300.0001.
Dear Mr. Dressel:
Hull & Associates, Inc. (Hull) is pleased to present the City of South Bend Redevelopment Commission
(Client) the following proposal to provide professional engineering services for the above referenced
project. The purpose of this document is to establish the Scope of Work as we understand it and to -
provide a fee schedule for the project.
Site Physical Setting and Background
The Site is located approximately one mile southwest of downtown South Bend. From 1876 to 1989,
activities at the Site included manufacturing of farm machinery and implements. The Site consists of several
vacant lots and commercial/light industrial businesses, and is bordered by commercial/industrial properties
to the southwest, south, and east of the Site; and an active rail line along the northern boundary of the
Site. Residential properties are located across the western and northern boundaries of the Site. The Site is
comprised of both vacant developed parcels totaling approximately 14.45 acres (+/-) of land located
near the intersection of Chapin Street and Oliver Plow Court in South Bend, Indiana. The Site formerly
comprised approximately 36 acres of land, but the City and private entities have redeveloped portions of
the Oliver Industrial Park, effectively removing certain parcels of the Site from inclusion in the VRP.
Multiple environmental assessments have been conducted at the Site. Soil sampling completed thus for has
revealed that benzo(a)pyrene, dibenz(a,h)onthracene, tetrachloroethene, and TPH (historically detected in
one location by obsolete method 41 8.1) are the only chemicals of concern (COCs) in soils that historically
exceeded their respective VRP Tier II Nonresidential Cleanup Goals. Hull coordinated excavations in May
through June 2016 that removed the last of the known COCs in soils at the Site. Soil remediation is now
considered complete and a summary report documenting these activities will be submitted to the City in
July 2016.
Extensive on- and off -Site groundwater testing completed thus far has revealed that tetra chloroethene
(PCE), trichloroethene (TCE), and vinyl chloride (VC) are the only COCs in groundwater that exceed their
respective VRP Tier II Nonresidential Cleanup Goals or the Indiana Department of Environmental
Management's (IDEM's) 2012 Remediation Closure Guide (RCG) Commercial and/or Residential
Groundwater Screening Levels.
In December 2011, Hull submitted a RWP for the Site that presented a general path forward for
additional assessment and remediation pursuant to VRP requirements. In May 2013, IDEM responded with
comments to the RWP. The City and Hull responded to IDEM's comments in a letter dated August 1, 2013.
That August 1, 2013 letter outlined additional assessment activities that would be initiated by the City,
which were subsequently completed. After ongoing correspondence between the City, Hull, and IDEM that
corroborated general agreement that the Site was on an acceptable path toward an appropriate
groundwater remedy, Hull submitted an amended RWP in December that proposed limited soil excavation
and a relatively extensive on -Site groundwater remedy. To date, IDEM has not issued formal approval of
6397 Emerald Parkway, Suite 200 • Dublin, Ohio 43016

the December 2015 RWP, but issued interim approval to the City to conduct the limited soil excavations in
Spring of 2016. As stated above, those excavations were completed by Hull and its subcontractor in
May -June 2016.
In telephone conversations between Hull and IDEM in June and July 2016, IDEM has verbally indicated that
it will also issue interim approval to the City to implement the groundwater remedy during Summer 2016
pending final review and comment on the December 2015 RWP. Given the current status of the Site, the
following additional activities are proposed:
Task 1 Routine Groundwater Monitoring
Task 1 a Pre -Remedy; 180 days, 365, 545, and 730 Days Post -Remedy
As further explained in Task 3 below, Hull proposes to retain the services of Innovative Environmental
Technologies Inc. (JET) to introduce a groundwater remedy into the subsurface that will stimulate the
degradation of VOCs in groundwater beneath the Site. JET's scope involves reviewing certain
groundwater data collected by Hull to establish a baseline and to evaluate the effectiveness of the
remedy after it is initiated. Before the remedy is initiated, and 180 days, 365 days, 545 days, and 730
days following the remedy event, Hull will collect groundwater samples from monitoring wells in the vicinity
of and downgradient from the PRB walls and analyze the samples for the following parameters:
- Volatile organic compounds (VOCs) in accordance with U.S. EPA Method 8260;
- Ethene, ethane, and methane in accordance with Method RSK 75;
- Sulfate in accordance with U.S. EPA Method 300.0; and
- Total and dissolved iron in accordance with U.S. EPA Method 6010.
Groundwater samples during these events will be collected using low -flow methods. During low -flow
sampling events, the following parameters will be monitored:
- Groundwater elevation;
- Dissolved oxygen;
- Oxidation-reduction potential;
- Specific conductivity;
- pH; and
- Temperature.
Groundwater samples will be collected from monitoring wells MW-1S (shallow screened depth), MW-11
(intermediate screened depth), MW-1 D (deep screened depth), PMW-1 1, MW-135, MW-145, MW-165,
MW-171, MW-17D, HMW-19, MW-20S/D, MW-21 S/D, MW-22S/D, MW-23S/D, MW-24, MW-25S/D,
MW-26S/D, MW-27S/D, MW-28S/D, MW-29S/D, and MW-305/D and submitted to the laboratory for
VOC analysis using U.S. EPA Method 8260. This cost estimate also includes costs for laboratory analyses
on samples collected from replacement monitoring wells installed as part of Task 2 below. To save some
cost, this cost estimate assumes that samples from only 32 of the aforementioned monitoring wells will be
analyzed for the additional parameters requested by IET (ethane, ethene, methane, sulfate, and
total/dissolved iron). As noted in Task 2 below, we will attempt to negotiate with IDEM a reduced number
of replacement monitoring wells (and therefore groundwater samples that must be analyzed) to save costs
for the City wherever possible.
Duplicate samples will be collected at randomly selected monitoring well locations. Field/equipment
blanks will also be collected and submitted along with a trip blank for analysis as part of QA/QC of field
procedures. Purge and decontamination waters will be collected and stored in U.S. DOT -approved 55-
gallon drums. Costs to remove, transport, and dispose of up to twenty 55-gallon drums of containerized
groundwater (which is presumed to be non -hazardous) are included in this task.

Task 1 b Interim Quarterly Groundwater Monitoring
Groundwater samples will be collected from monitoring wells MW-1S (shallow screened depth), MW-II
(intermediate screened depth), MW-1 D (deep screened depth), PMW-1 1, MW-135, MW-145, MW-165,
MW-171, MW-17D, HMW-19, MW-20S/D, MW-21 S/D, MW-22S/D, MW-23S/D, MW-24, MW-25S/D,
MW-26S/D, MW-27S/D, MW-28S/D, MW-29S/D, and MW-30S/D and submitted to the laboratory for
VOC analysis using U.S. EPA Method 8260. This cost estimate also includes costs for laboratory analyses
on samples collected from replacement monitoring wells installed as part of Task 2 below. As noted
above, Hull will endeavor to reduce as much as possible the number of samples to be analyzed to save the
City costs wherever possible.
Duplicate samples will be collected at randomly selected monitoring well locations. Field/equipment
blanks will also be collected and submitted along with a trip blank for analysis as part of QA/QC of field
procedures. Purge and decontamination waters will be collected and stored in U.S. DOT -approved 55-
gallon drums. Costs to remove, transport, and dispose of four 55-gallon drums of containerized
groundwater (which is presumed to be non -hazardous) are included in this task.
For the proposed sampling events, Hull will continue to deploy passive diffusion bag (PDB) samplers in all
monitoring wells, which are a significantly more cost-effective .sampling methodology that has been
accepted by IDEM. PDBs are polyethylene bags filled with onalyte-free water that are hung in monitoring
wells for a minimum of 14 days. Field personnel return to the monitoring well, retrieve the sampler, and
collect the sample by filling sampling vials in the same manner as traditional methods. Significant savings
are realized by reducing mobilization, purging., and sampling time; by minimizing the volume (and thereby
cost and environmental footprint) of field materials such as low -flow tubing; and by eliminating most
equipment rental costs. Laboratory analytical subcontractor costs for this Task include the cost of replacing
PDBs during each semi-annual sampling event at each well, and for Level IV QA/QC reporting by the
laboratory.
Task 2 Replace Decommissioned Monitoring Wells
IDEM has indicated that certain monitoring wells that have been decommissioned to accommodate
redevelopment of the parcels sold to Indiana -Michigan Power and ABC Supply must be replaced. This
cost estimate assumes replacement of two nested shallow and intermediate monitoring well clusters and
one nested shallow, intermediate, and deep monitoring well cluster — for a total of seven monitoring wells
at three separate locations — will be required. However, because the monitoring well network is already
relatively extensive, Hull will attempt to negotiate fewer monitoring wells than the proposed seven.
Hull will work with the drilling subcontractor, the property owners, and the appropriate City and St. Joseph
County authorities to arrange for access for the work and to clear utilities and to prepare appropriate
permits for drilling in the right-of-way, if necessary. Drill cuttings and sample purge and decontamination
water will be containerized and placed at a location designated by the City.
Following agreement between the City, IDEM, and Hull on the final quantity and locations of the monitoring
wells, the nested monitoring wells will be installed on- and/or off -Site at the agreed upon locations. Soil
borings associated with the proposed monitoring wells will be drilled using 4.25-in., inside -diameter
hollow -stem augers and continuously sampled using 24-in. split -spoon samplers to the appropriate depths
(currently proposed to be 25 feet for shallow wells, 40 feet for intermediate wells, and 55 feet for the
sole deep well at one clustered location). The final locations of the monitoring wells may be modified
based on field observations. Although the deepest boring at each location will be continuously sampled,
soil samples are not proposed to be submitted for laboratory analyses as part of the monitoring well
installation. Regardless, as standard procedure, the Hull field personnel will screen soils with a
photoionization detector (PID) during sail boring logging to evaluate for the presence of soil contamination.
Mr. Chris Dressel
July 25, 2016
SBI074.300.0001
Page 4
Monitoring wells will be constructed of two-inch inside diameter Schedule 40 PVC slotted screens and
risers. Once the targeted depth has been reached, the well column will be slowly lowered to the base of
the borehole. A clean silica quartz sand filter pack will be placed around the screen and will extend no
more than two feet above the top of the screen. Sodium bentonite chips or pellets will then be placed on
top of the sand pack. Above the chips or pellets, a thick bentonite slurry will be pumped into the annular
space using a tremie pipe to a depth of approximately three feet below ground surface. The remaining
three feet will be filled with concrete to anchor either a flush -mount manhole or above -grade protective
casing.
Monitoring wells will be developed following installation to remove fines that may have entered the well
screen or filter pack during installation. Well development activities will continue until pH, temperature,
and conductivity have stabilized for three consecutive well volumes, or until five well volumes have been
removed, whichever is greater. Development waters will be collected and stored in a DOT approved 55-
gallon drum. Costs to remove, transport, and dispose of approximately 25 55-gallon drums of
containerized groundwater and drill cuttings (which are presumed to be non -hazardous) are included in
this task.
Following the installation of the new monitoring wells, the top of casing and ground elevations of the new
wells will be surveyed so that the groundwater elevations measured in these wells can be compared
relative to the other wells in the monitoring network. Costs include a surveying event from Jones Petrie
Rafinski to tie the new wells into the monitoring network.
Task 3 Implement Groundwater Remedy
Following interim approval from IDEM of the groundwater remedy proposed in the December 2015 RWP,
Hull will retain the services of IET to introduce a groundwater remedy into the subsurface that will stimulate
the degradation of VOCs in groundwater beneath the Site. A pre -remedy on -Site meeting will occur
between Hull, IET, the City, and affected property owners to coordinate staging of materials prior to the
injections; to secure a water supply for the injections; and to present the overall scope and schedule of the
events to all stakeholders. Hull will provide limited oversight during the groundwater remedy but is not
proposing to remain on -Site full time for the duration of the injection event, currently projected to take nine
(9) days to complete. As summarized in IET's proposal included in Attachment A, a groundwater remedy
consisting of injection of three permeable reactive barrier (PRB) walls at three locations is proposed. IET's
scope involves reviewing certain groundwater data collected by Hull to establish a baseline and evaluate
the effectiveness of the remedy after it is initiated. Before the remedy is initiated, and 180 days, 365
days, 545 days, and 730 days following the remedy event, Hull will collect groundwater samples from
monitoring wells in the vicinity of and downgradient from the PRB walls and analyze the samples for the
parameters presented in Task 1 a above. The laboratory data will be provided to IET and a brief
summary of the continued efficacy of the groundwater remedy will be prepared by IET and included in
Hull's quarterly reports as presented in Task 4 below. Finally, as requested by the City, Hull's standard
subcontractor markup will be reduced to 5% for IET's costs.
Task 4 Prepare Quarterly Reports and Various VRP Documents
This task is proposed to assist with a public notice of the intent of the City to proceed with the proposed
remedy, should it be required by IDEM. This task also includes effort to prepare quarterly reports
summarizing data collected during each pre- and post -remedy sampling event, for a total of nine
quarterly reports. The quarterly report summarizing data collected following the 180-day post remedy
sampling event as presented in Task 1 a above will include a summary of the groundwater injection event.
Also, the quarterly report summarizing data collected following the monitoring well replacement event will
contain a narrative and monitoring well construction diagrams summarizing monitoring well installation
activities.
Mr. Chris Dressel
July 25, 2016
SBI074.300.0001
Page 5
Assuming that only one groundwater injection event occurs, and assuming that the remedy is effective with
the single injection event, the ninth quarterly report will be prepared as a Remedial Completion Report
(RCR). A RCR Completeness Checklist, which is required by IDEM, will be prepared and submitted with the
RCR. Finally, assuming no additional environmental activities occur, the RCR will request a Covenant Not -
to -Sue (CNS) for the Site. This task includes time to coordinate final documents between IDEM and the City
to the end of obtaining the CNS.
Task 5 Proiect Management Meetings and Correspondence
This task will be reserved for project management activities such as updating health & safety plans, email
and telephone correspondence with all stakeholders, and attending one meeting in Indianapolis with IDEM.
SCHEDULE
Hull will begin groundwater sampling activities in September 2016, and will schedule the soil vapor probe
installation and sampling as soon as practicable, which we estimate to be in early- to mid -July 2016.
COMPENSATION
A breakdown of costs is attached as Table 1. The fees have been developed based on our estimate of
hours for each labor category expected to be involved in the project. The project will be billed on a four -
week basis with payment due to Hull within thirty days after receipt of an invoice.
ADDITIONAL WORK
Additional work beyond the Scope of Work defined herein shall not be performed until such time as an
amendment to this proposal, including the scope of the additional work and associated costs, has been
prepared in writing to address the additional work and said amendment has been approved by the Client
in writing.
Specific items not within the Scope of Work on this project include, but are not limited to the following
1. Installation of more than seven (7) monitoring wells at the Site;
2. Collection of more than 9 quarters of groundwater samples as described in Tasks 1 a and
1 b above;
3. Completion of more than one groundwater remedy injection event as described in Task 3
above; and
A. Disposal of groundwater or soil cuttings that are determined to be hazardous.
No amendment to this proposal shall be required in situations where additional work may be necessary, as
a result of unanticipated or unidentified conditions including, but not limited to, the presence of unidentified
or mislocated buried utilities, structures, or objects and unanticipated hazardous materials and/or
hazardous or dangerous circumstances, to complete previously identified tasks. Hull shall be compensated
for the actual time spent performing this additional work and other direct expenses and subcontractor fees
at the billing rates outlined in Table 2.

Dear Mr. Stuart:
Innovative Environmental Technologies Inc. (IET) has included a revised remedial design and
quotation for the Oliver Plow site located in South Bend, IN. The site has been identified as
having impacted soils and groundwater due to the historic use of tetrachloroethene (PCE) and
trichloroethene (TCE). Based on the provided soil borings, groundwater concentrations,
screened intervals for monitoring points and historic geochemical parameters, a design which
will stimulate reductive dechlorination processes in the subsurface is proposed. Concentrations
of PCE and its reaction products, trichloroethene (TCE), cis-1,2-dichloroethene (cis-1,2-DCE) and
vinyl chloride (VC) indicate that reductive dechlorination is occurring at the site at a rate that
needs to be stimulated.
The recommendations presented herein are based on IET's experience at over 200 similar sites,
IET's experience with a variety of oxidative and reductive technologies and IET's ability to
integrate a variety of remedial products forthe optimal remedial process.
Further, the remedial approach presented herein is covered by three IET United States Patents
and one IET United States Patent Application.
1) "Apparatus for In -Situ Remediation Using a Closed Delivery System", Patent Issue Date: May
16, 2006 Patent Number 7,044,152.
2) "Method for Accelerated Dechlorination of Matter', Patent Issue Date: October 31, 2006,
Patent Number 7,129,388.
3) "Method for Accelerated Dechlorination of Matter', Patent Issue Date: May 12, 2009, Patent
Number 7,531,709 (continuation of "388").
4) "Method for the Treatment of Groundwater and Soils Using Mixtures of Seaweed and Kelp",

OBJECTIVE
It shall be the objective of IET to promote the conditions in -situ, necessary for accelerated
dechlorination via both abiotic and microbial processes along three permeable reactive barriers
(PRB). Further, through the introduction of a 1-3 micron zero valent iron colloidal suspension,
reduction of the dissolved phased CVOCs will occur while initiating the production of hydrogen for
microbial mineralization processes in order to mitigate off -site migration and further stream
impact.
The remedial plan described herein is designed to treat source area and residual contamination
through reductions of CVOCs in the saturated zones. No additional equipment or maintenance
will be required and because no waste streams will be generated, no disposal permitting will be
required during the remedial effort. IET proposes to implement a program, which shall:
• Supply all essential microbial elements necessary for dechlorination processes to occur.
• Introduce zero valent iron (ZVI) to further and quickly address dissolved phase compounds
while acting synergistically with the anaerobic processes.
A map of the site and the proposed PRB locations is presented below.
PERMEABLE REACTIVE BARRIERS
U.T. -t
PRB-A encompasses approximately an area of 6,280 square feet. This area will be treated with a
25 foot vertical contaminated zone from 20-45 feet below ground surface (bgs). An injection
radius of 20 feet is proposed to treat the area. Based on the area to be treated and the injection
radius, 5 injection points would be required to treat the area with 5 injection intervals at 23-25,
28-30, 33-35, 38-40 and 43-45 feet bgs. Soil concentrations are assumed to be moderate to low

in PRB-1 based on groundwater concentrations present, therefore, soil absorption correction is
moderate to low (IET has assumed the value to be 5%).
The Freundlich equation is an adsorption isotherm that relates the concentration of a solute on
the surface of an adsorbent to the concentration of the solute in a liquid. The Freundlich
equation is used to determine the theoretical mass of contamination adsorbed to the soil. The
mass of contaminant in the soil was determined using the soil adsorption correction (item 1).
The K constant is a figure relating the capacity of the adsorbent for an adsorbate and the 1/n
constant is a function of the strength of adsorption (American Water Works Association, Water
Quality and Treatment, 1999 ). The Freundlich equation is listed below:
qe=KCel/n
The theoretical values of K and 1/n are found in the following references: (Dobbs and Cohen,
1980/Faust and Aly, 1983).

PRB-C encompasses approximately an area of 16,328 square feet. This area will be treated with
a 25 foot vertical contaminated zone from 20-45 feet below ground surface (bgs). An injection
radius of 20 feet is proposed to treat the area. Based on the area to be treated and the injection
radius, 13 injection points would be required to treat the area with 5 injection intervals at 23-25,
28-30, 33-35, 38-40 and 43-45 feet bgs. Soil concentrations are assumed to be moderate to low
in PRB-3 based on groundwater concentrations present, therefore, soil absorption correction is
moderate to low (IET has assumed the value to be 5%).
SCOPE OF SERVICES
1. SATURATED ZONE INJECTIONS
The following sequence will be followed when injecting into the saturated zone in the
on -site and off -site treatment areas.
1. Subsurface Pathway Development
Initially, nitrogen gas shall be delivered to the subsurface via IET proprietary
injection trailer system. Nitrogen gas is used so as not to introduce oxygen
into an environment targeted for anaerobic processes. The gas is introduced at
approximately 175 psi such that delivery pathways and voids are established.
Pathway development shall be verified by observing a substantial pressure
drop.
2. Sodium Sulfite, Nutrient and Micro Nutrient Injection
A solution of sodium sulfite, nutrient and micro nutrients (riboflavin and
vitamin B-12) are immediately injected into the subsurface fractures and voids
that were developed during the gas injection step. Sodium sulfite acts as an
oxygen scavenger, iron reducer and sulfate source. As an oxygen scavenger,
the sodium sulfite prevents the oxidation of the ZVI by the dissolved oxygen
while promoting anaerobic conditions that are favorable for the
biodegradation of the CVOCs. Nutrients, injected as organic ammonia and
ortho-phosphate, are required for the maintenance of the microbial metabolic
pathways, ATP/ADP synthesis and organelle development.
3. ZVI and Provect-IR Injection
ZVI and Provect-IR are injected immediately following the sodium
sulfite/bioslurry solution to reduce concentrations of dissolved -phase CVOCs
while providing for rapidly generated hydrogen for the microbial stimulation.
Hull & Associates Inc.
Page 8
4. Sodium Sulfite/Nutrient Injection
This injection is conducted to clear the injection lines and to provide for in -situ
mixing and penetration of the Provect-IR product.
5. Post Liquid Injection - Gas Injection
Lastly, the injection lines are cleared of liquids and all injectants are forced
into the created formation and upward into the vadose zone.
Once the injection cycle is complete, the injection point is capped to allow for the pressurized
subsurface to accept the injectants. The targeted saturated zone at the site shall receive
calculated dosages of the individual remedial components based on biological and
stoichiometric demands and an estimated pore volume based on the known geology of the site.
Equipment Description
The injections small occur via IET's mobile oxidation injection trailer and IET's direct -push
equipment as described:
Injection Lines: High Pressure Stainless steel Braided Rubber one inch diameter hoses
Injection Trailer: IET Self-contained injection trailer, consisting of: two 120 gallon conical tanks

APPENDIX 3: TECHNOLOGY DISCUSSION
The options available for a cost-effective and reliable technology to treat chlorinated
hydrocarbon contaminants such as tetrachloroethene (PCE), trichloroethene (TCE), cis-1,2-
dichlorethene (cis-1,2-DCE), and carbon tetrachloride in groundwater have in recent years
moved away from traditional pump -and -treat processes, especially in cases where:
• NAPL, micro -emulsions or high concentration adsorbed materials are present leading to
high dissolved phase concentrations.
• Access to groundwater is restricted by surface structures or uses.
• Local restrictions forbid the implementation of other available technologies such as air
sparging or natural attenuation.
• Pump and Treat technologies have been applied, but have reached asymptotic removal
rates.
• Contamination is extensive and concentrations are too high for risk based closure but
otherwise relatively low (typically 100-7500 ppb).
• The migration of dissolved Chlorinated Aliphatic Compounds (CAHs) across property
boundaries or into adjacent surface water presents a long-term remediation
requirement.
• The vertical migration of free phase CAHs (DNAPL) into underlying drinking water
aquifers is a concern.
The environmental chemistry of a site in part determines the rate of biodegradation of
chlorinated solvents at that site. The initial metabolism of chlorinated solvents such as
chloroethenes and chloroethanes in ground water usually involves a biochemical process
described as sequential reductive dechlorination. The occurrence of different types and
concentrations of electron donors such as native organic matter, and electron acceptors such as
oxygen and chlorinated solvents, determines to a large degree the extent to which reductive
dechlorination occurs during the natural attenuation of a site. To accelerate the natural
processes, ZVI and enhanced microbial dechlorination processes are proposed to be utilized at
the site. The utilization of coenzymes, oxygen scavengers and nutrients insures that little or no
lag phase in the process is experienced and that the most efficient pathways may be utilized.
Program Elements
Nutrient: Critical to the sustained microbial activity and general microbial health is sufficient bio
available nutrient. IET has incorporated nitrogen and o-POa into the remedial program such
that organelle and ATP-ADP formation is not limited throughout the microbial respiratory
process.

Provect-IR: Provect-IR contains ZVI to uniquely elicit ISCR reactions, and it is composed of a
hydrophilic, solid and complex carbon source hence it should generate little or no methane (< 5
mg/L). Provect-IR consists of various organic hydrogen donors, such as propionate, yeast
extract and kelp meal that target the production of H2 levels that effectively stimulate the
reductive dechlorination process. In addition Provect-IR also incorporates the oxygen scavenger
sodium sulfite and the methane inhibitor red yeast rice, making it suitable to address multiple
facets and areas of concern during the remedial process. A more extensive description of the
purpose of each reagent is presented below.
Oxygen Scavenger (sodium sulfite): Reductive dechlorination only occurs in the absence of
oxygen; and, the chlorinated solvent actually substitutes for oxygen in the physiology of the
microorganisms carrying out the process. As a result of the use of the chlorinated solvent during
this physiological process it is at least in part dechlorinated. The site shall have introduced to
the subsurface an oxygen scavenger to ensure that this process would occur immediately.
Zero Valent Iron (ZVI): ZVI may chemically be thought of having been the product of the
positively charged metal ions receiving electrons to become the electrically neutral pure metal.
The term "reduction" is applied to any chemical reaction that added electrons to an element.
Thus ZVI is a reduced material. In a similar manner, the chemical term "oxidation" refers to any
chemical reaction that removes electrons from a material. For a material to be reduced, some
other material must be oxidized. In the reduction of a chlorinated compound the zero valent
iron is oxidized. Zero valent iron enhanced abiotic degradation of chlorinated volatile organic
compounds (CVOCs) is essentially a reductive dechlorination process, which uses granular cast
iron as the reducing agent, and produces final reaction products such as ethane, ethene, and
chloride ions in the degradation of TCE. During this treatment process, the corrosion of iron by
water dominates the chemical processes. The corrosion of iron by water results in ferrous ion
generation, hydroxyl ion generation, and hydrogen gas generation. This results in a decrease in
ORP (oxidation/reduction potential; that is, reducing conditions are produced) and an increase
in pH. Accordingly, the end products of this reaction are ferrous iron, chloride ions, and the
dehalogenated compound.
Frequently remedial sites show insignificant or incomplete dechlorination, especially those with
high aquifer sulfate levels. It is generally overlooked that the rapid conversion of sulfate to toxic
free sulfide during bacterial reductive dechlorination plays a significant role in the "stalling" of
the biotic stalling frequently observed. Accumulation of free sulfide is especially important in
sites that display both high sulfate and low available iron. Reductive dechlorination inhibition
by free sulfide has been observed in microcosms conducted for high sulfate field sites. Free
sulfide toxicity to microorganisms can be prevented if ferrous iron precipitates the free sulfide.
Further, iron sulfide mineral precipitates have been shown to catalyze reductive dechlorination
of chlorinated solvents at rates comparable to metallic iron, on a surface area normalized basis.
Microcosms performed at high sulfate sites have been showed to both remove free sulfide

toxicity to dehalogenating bacteria and to enhance catalytic reductive dechlorination when
ferrous iron is added. Further, ferrous iron, itself, may act as an electron donor.
Injected, colloidal reactive iron is a promising technology, which may be applied, in a synergistic
approach with compatible technologies. There are two primary reactions with CAHs that take
place which will consume the iron and require stoichiometric consideration:
the anaerobic iron corrosion reaction in which water is disassociated to form hydrogen gas;
and
• the direct adsorption of a chlorinated hydrocarbon onto the surface of the iron, followed by
reductive dehalogenation.
Recent research on elemental iron systems suggests that four mechanisms are at work during
the reductive process:
• First, the Fe' acts as a reductant by supplying electrons directly from the metal surface to an
adsorbed halogenated compound.
• Second, hydrogen gas is generated by the anaerobic corrosion of the metallic iron by water.
• Third, metallic iron may act as a catalyst for the reaction of hydrogen with the halogenated
hydrocarbon using the hydrogen produced on the surface of the iron metal as the result of
anaerobic corrosion with water. Theoretically, these reactions are not kinetically effective
without a catalyst; thus, it is thought that impurities in the iron or surface defects act as that
catalyst.
• Fourth, solubilized ferrous iron can also act as a reductant, albeit at a rate at least an order
of magnitude slower.
Hydrogen gas can be used for reductive dehalogenation by the following reaction:
Hz + X-CI = X-H + H' + CI'
Vitamins: Recent studies suggest that metal — containing coenzymes, found in certain types
of anaerobic microorganisms, and can reductively dechlorinate one- and two -carbon
solvents. Cobalt -containing corrinoid cofactors such as vitamin B12 mediate the reductive
dechlorination of carbon tetrachloride and tetrachloroethene.in these biological systems
the rate -limiting step to complete dechlorination to ethylene is the last stage conversion of
vinyl chloride. The rate of that process has been found to be significantly enhanced by the
presence of vitamin B12, which acts as an electron carrier. It is the core of B12, which
contains cobalt, and the various oxidation states the cobalt obtains, which allows for the
electron transfer intra-cellularly. The existence of the cobalt core has also been seen to
catalyze the surface reaction of the iron lowering the necessary activation energy required
for the electron transfer.

Technology Summary: The application of these two synergist technologies: colloidal iron and
microbial reductive dechlorination process may be further enhanced through microbial
amendments and reducing agents. The proposed treatment technology presented herein
applies these technologies.
Critical to the success of the proposed remedial technologies is the successful delivery of the
various materials to the targeted groundwater and soils.
