SITE HISORY
1
Attachment A: Site History
Site Background
The site consists of a 40 acre parcel of property located at 210 South Estes Drive, Chapel
Hill, Orange County, North Carolina. The site is currently used as a commercial center
which includes two main buildings, one located on the north portion of the property while
the second is located in the south central portion of the property. There are also several
out parcel buildings. The surrounding properties include; to the north, residential
properties, to the east, a church that houses a child daycare and pre-school and residential
properties, and to the south and west, commercial properties.
In an Underground Storage Tank Closure Report submitted by Withers and Ravenel
(W&R) on June 1, 1995, it was reported that the building on the northern portion of the
property contained a grocery store and a dry-cleaner. W&R along with A&D
Environmental closed an underground storage tank (UST), by removal, which was
located adjacent to the dry-cleaners. According to the report, the dry-cleaner facility
ceased operations prior to tank closure activities. The UST was used to store number 2
fuel oil for heating the commercial space. During closure activities, two soil samples
were collected at the base of the tank bed. Analytical results from one of the soil samples
showed the presence of tetrachloroethene (PCE) and trichloroethene (TCE).
Due to the presence of chlorinated ethenes in the soil, a groundwater assessment was
conduct in May and August 1995 by W&R, at which time, nine groundwater wells were
installed and sampled (2W-1 through 2W-8 and 2W-2D). Groundwater samples were
collected from the monitoring wells and analyzed for VOCs (volatile organic
compounds). Analytical results showed groundwater samples from wells 2W-1, 2W-3,
2W-4, and 2W-6, contained PCE and TCE at concentrations above their respective NC
2L Groundwater Standard. Temporary wells HA-1 and HA-2 were installed inside the
former dry-cleaning space. The wells were sampled and analyzed for VOCs. The results
from the temporary wells showed PCE at concentrations above the NC 2L Groundwater
Standard.
In 2007, the property was bought by Madison University Mall, LLC at which time,
petitioned NCDENR-DSCA Program to execute an Assessment and Remediate
Agreement. Since entering into the program, additional site assessments have been
performed by W&R. During the assessment activities, six additional groundwater
monitoring wells (MW-1 through MW-6) were installed on the site and on the adjacent
property to the east of the site.
Results from the groundwater assessment showed the highest concentrations of
chlorinated ethenes in monitoring wells 2W-5, MW-2 and MW-3. The groundwater
contaminant plume appears to have migrated east onto the adjacent property. Overall,
analytical results from samples collected in groundwater wells located hydraulically
TI
down -gradient from the wells 2W-5, MW-2 and MW-3 are at concentrations near or
below their respective NC Groundwater Standard.
Previous Remedial Actions
In a Summary of Soil Remediation dated March 7, 1996 that was submitted by W&R, it
was reported that soil was excavated from under the former dry-cleaners and an area
located north and east, adjacent to the former dry-cleaning facility. During the soil
remediation event, 400 cubic yards of soil were removed and transported off -site for
disposal.
On five different occasions, W&R conducted Aggressive Fluid Vapor Recovery (AFVR)
events in an effort to reduce VOCs concentration in the groundwater at the site. The
AFVR events were performed in January, February, and September 2009, and in March
and October, 2010. In January, September 2009 and October 2010, the AFVR was
conducted on wells MW-2 and 2W-5 while in February 2009 and March 2010 the AFVR
was conducted on MW-2 only. Results from groundwater samples taken after the
AFVRs showed a substantial reduction in contaminant concentrations. However, results
from the follow-up sampling events showed a contaminant rebound to concentrations
similar to pre AFVR concentrations.

Attachment B: Hydrogeologic Description
Regional Geology
The site is located south of central Chapel Hill, Orange County, North Carolina. Orange
County lies within the Piedmont Physiographic Province. According to the North
Carolina Geologic Survey (NCGS), the Piedmont Province is a region of generally
rolling, well rounded hills and ridges. Elevations within the Piedmont range from 300 to
600 feet above mean sea level (ft msl) near its border with the Coastal Plain to 1,500 ft
msl at the foot of the Blue Ridge.
Chapel Hill is located in the southeast portion of Orange County. The Geologic Map of
North Carolina (1985) shows Chapel Hill is located on the western edge of the Triassic
Basin and is underlain by arkosic sandstone of the Chatham Group. Carolina Geological
Society describes the "Durham-Wadesboro (Triassic) basin is surrounded and presumed
underlain by crystalline Piedmont complex composed of acid igneous intrusives, meta-
volcanics, meta -sediments and high -rank metamorphic rocks" (Brian, 1977). They
continue "Continental sediments preserved in the Durham-Wadesboro (Triassic) basin
include maroon to gray fanglomerate, conglomerate, feldspathic sandstone, greywacke,
argillite, siltstone, mudstone, black shale, and minor amounts of chert and coal".
Site Specific Hydrogeology
During previous environmental investigations, it was reported that the first ten to fifteen
feet of subsurface material underlining the site is a sandy silt which grades into a silty
sand. Beyond the upper ten to fifteen feet is a siltstone which is in turn, underlain by an
arkose sandstone (see Attachment B-1). The siltstone appears to be the thickest on the
northern portions of the site and eventually pinches out along the southern portions of the
site. In January 2011, W&R advanced seven exploratory borings along the axis of the
plume to confirm subsurface conditions. Soil encountered during the exploratory drilling
was consistent with the previous environmental investigations (see Attachment B-1).
Based on groundwater analytical data and subsurface stratigraphy, W&R believes that a
pilot study should be performed in the silty sand horizon overlying the siltstone, in the
vicinity of 2W-5.
Historic groundwater table data shows depth to water levels ranging from three feet to
five feet below ground surface (BGS) on the subject property, and six to 11 feet BGS on
the adjacent property located east (see Attachment B-2). Groundwater elevation data
collected since 2008 shows a consistent groundwater flow to the east, toward North
Fordham Boulevard.
On January 28, 2011, W&R conducted hydraulic conductivity test in three shallow set
wells, 2W-4, 2W-5, and 2W-6, and one deep set well, MW-2. The hydraulic conductivity
tests were performed by pumping the wells dry using a submersible pump, then recording
the rate of water level recovery in the wells. The results of the hydraulic conductivity
tests showed values from shallow set wells ranged from 0.87 ft/day in 2W-6 to 0.23
ft/day in 2W-5, while the deep set well MW-2 showed a hydraulic conductivity value of
0.064 ft/day (see Attachment B-3).
Using the hydraulic conductivity values from 2W-5 and the thickness of the silty sand
layer within the pilot study injection zone, transmissivity was calculated to be 0.69
ft2/day using the following equation:
T=Kb
Such that:
T=Transmissivity (ft2/day)
K=Estimated Hydraulic Conductivity (ft/day)
b=Saturated Thickness of the Aquifer (ft)
During the exploratory drilling activities, three geotechnical samples were obtained from
borings that were advanced in close proximity to shallow set wells 2W-4, 2W-5, and 2W-
6 and submitted for laboratory analysis. Samples (HT-2 and HT-3) collected in close
proximity to 2W-4 and 2W-5 were submitted from the silty sand horizon, while the
sample (HT-7) collected in close proximity to 2W-6 was submitted from the upper
portion of the sandstone for a sieve analysis. The results were plotted on a textural
classification triangle (see Attachment B-4). The effective porosity values in 2W-4,
2W-5, and 2W-6 were estimated to be 0.22, 0.20, and 0.23, respectively.
The hydraulic gradients for monitoring wells 2W-4, 2W-5, 2W-6 were estimated from the
January 2011 Groundwater Contour Map (see Attachment H-Figure 3). The hydraulic
gradients in 2W-4, 2W-5, and 2W-6 were calculated to be 0.018 ft/ft, 0.016 ft/ft, and
0.016 ft/ft, respectively.
Using the values listed above, estimates of groundwater seepage velocity in the vicinity
of wells 2W-4, 2W-5, and 2W-6, were calculated using the following equation:
V = ki
Ile
Such that:
V=Seepage Velocity (ft/day)
K=Estimated Hydraulic Conductivity (ft/day)
i=Estimated Hydraulic Gradient (ft/ft)

Subject: Treatment of CVOCs using ISCR Technology
Former American Cleaners, Chapel Hill, North Carolina
Adventus Proposal No. AAI11-160
Dear Mr. Bellis:
Please find herewith a conceptual remedial design and cost estimate for employing EHC® in
situ chemical reduction (ISCRTM) 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.
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 9,000,000 tons of soil/sediment impacted by recalcitrant compounds as part of the
company's DARAMEND® 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 and
regional regulatory authorities within the USA/Canada (Figure la) 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 dehalogenators and halorespiring species. Finally, the small ZVI particles
(ca. <5 to 45 µm) 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 are commonly 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 DCE for TCE). Hence, the ISCR
technology is microbiologically based in that we rely on indigenous microbes to biodegrade
AAI11-160 EHC NC Site
Li;
() ADVENTUS
EHC Design & Cost Estimate
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.
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-L) 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 COI destruction under ISCR conditions are
different from the typical pathways. The primary COls in the Site groundwater are PCE/TCE
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. Mark 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 for source area treatment in clayey lithology (PCE and catabolites), Former dry
cleaner, Oregon
• 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
Carolina
• EHC for complete plume treatment using multiple reactive barriers (CF, TCE and
OCPs), Confidential site, Southeast USA
• EHC injection PRB for plume management (CT, CF), confidential site, Kansas
• EHC injection PRB for plume management (cis-DCE and VC), confidential site, Ohio
• 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
EHC has been accepted by the State of North Carolina and many other regulatory agencies.
The product is made in the USA and 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.
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 (Le., 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;
• 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;
AAI11-160 EHC NC Site 5
64,S) ADVENTUS
EHC Design & Cost Estimate
• 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 / sequestration as a major "removal" mechanism, ala oils;
• ISCR. 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 Dolfing et al, 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.q., 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 COIs.

UNDERSTANDING SITE CONDITIONS AND GOALS
The aquifer lithology is composed of sands and silts with depth to groundwater roughly
around 5 ft bgs in the area of concern. The groundwater is impacted by chlorinated ethenes
including PCE and its daughter products - collectively known as the constituents of interest
(COI). COI concentrations as high as 40,000 ug/L have been observed proximal to well MW-
2. The source of contamination is known and is attributed to historic on -site operation. Table
1 summarizes the site conditions.

CONCEPTUAL DESIGN - Pilot
The project goal is to perform a pilot test in the area around MW-2 and 2W-5 to address
cVOCs in groundwater and to restore the groundwater via ISCR, uniquely induced via the
use of the EHC. Figure 5 shows the proposed treatment area and location of injection points.

EHC is typically provided in 50-Ib bags as a dry powder and mixed with water on site into
aqueous slurry containing ca. 20-30% solids. Table 2 (next page) provides the EHC
requirements and injection details. An application rate of 0.45% by wt EHC to soil mass has
been proposed given that the concentrations of COI are high. EHC will be applied through 12
injection points, each spaced 9 ft apart to provide adequate distribution in the targeted area.
EHC will add a sufficient carbon source for the microbes; TOC concentrations greater than
20 mg/L are considered favorable for bioremediation because they provide a carbon and
energy source for microbes that participate in the dechlorination reactions (EPA, 1998). EHC
will add >20 ppm TOC to the aquifer formation. In addition, ZVI reactions are extremely
robust (effective under high or low DO/ORP conditions). Moreover, EHC will uniquely
establish /SCR conditions by promoting both chemical oxygen scavenging and biological
oxygen consumption. In addition, abiotic dechlorination reactions will be promoted in contact
with ZVi, and the ZVI will help buffer the aquifer.

PLEASE NOTE that the construction estimates presented 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 injection layout/number of injection points could be altered depending
on recommendations from the injection contractor and technology employed).
Adventus recommends sampling for a set of critical and non -critical parameters (see
attached) as part of baseline and continuous monitoring. We recommend that baseline
samples be collected from monitoring wells within the treatment area (MW-2) and 2W-5 to
establish current concentrations and existing geochemical conditions. Continuous monitoring
samples can be collected monthly to assess ISCR efficiency. It is our understanding that the
goal of the pilot is demonstrate significant reductions in cVOCs concentrations and not reach
AAI11-160 EHC NC Site 9
(() ADVENTUS
EHC Design & Cost Estimate
regulatory standards. Once the pilot test results are validated (3 to 6 months time), the
results will be utilized to develop the site -specific full scale remedial design.
TABLE 2 NOTES: If the estimated amount of slurry per point is problematic, the dimensions,
mass requirements, mixing and other injection details presented above can be readily
modified in the field based on site specific conditions (for example, the density of the slurry
can be changed to modify the total injection volume or the injection layout/number of injection
points could be altered depending on recommendations from the contractor).
OPTIONAL USE OF REACTIVE BOREHOLE SEALANT
It is very important to effectively seal the DPT bore holes, and HoleBlok+ provides an
excellent, reactive sealant to enhance overall remedial performance which should be
prescribed for the injection contractor. A total of 150 Ibs of HoleBlok+ would be required for
the pilot test.
OPTIONAL USE OF INOCULANTS FOR RAPID DCE DEGRADATION
The accumulation of DCE and other catabolites may indicate that the naturally occurring
microbial population may be catabolically limited and that the remedial process might benefit
from the addition of inoculants with known abilities to rapidly biodegrade DCE and related
compounds. Although not typically required for ISCR as defined above, inoculants have been
useful for these situations. Therefore once favorable redox conditions (ORP < -75 mV, DO
<0.2 mg/L, pH between 6 and 8.5) have been attained following EHC addition,
dehalococcoides (DHC) cultures could be added if DCE or VC are still present at high
concentrations.
The DHC inoculant will contain at least 1x10E10 cfu/ml of live bacteria including high
numbers of dehalococcoides species with known abilities to biodegrade DCE. The target
density of DHC cells in the treated aquifer areas will be 1x10E7 cfu/ml. A total of 3 L of
inoculum is required for the pilot test.

RE Standard Operating Procedure (SOP)
Adventus EHC"m Installation Procedures — Direct Injection
Dear Mr. Fay:
Thank you for the opportunity to provide you this SOP for the purpose of injecting
Adventus EHC.rm (EHC) for your upcoming project. Quantex proposes to use Direct Push
rigs and specialized injection equipment to assist in the in -situ remediation pilot test,
EHC, in the form of a dry powder will be mixed with water within batch tanks open to the
atmosphere, but contained within a truck/trailer. A pre -determined ratio of water and EHC
will be mixed together to form a liquid slurry. This will be accomplished by using heavy-
duty mixers to bring the EHC solution to the desired wet density as specified in the
remedial action plan.
AD mixing will be performed on site within a protected area away from pedestrians and
non -contracted personnel. Quantex proposes that EHC will be staged in a dry container
away from oxidizers and protected from exposure to the elements. In order to minimize
mixing cycles, container sizes will be selected which will best replicate injection volumes.
Total volume for each injection point will be closely monitored and documented.
Upon completion of mixture, the EHC solution will be pumped to an injection holding tank.
Because of the rather thick slurry, flow meters will not be used for this project. Instead, a
pre -determined volume of the EHC solution will be mixed prior to injection. Because of the
potential of varying hydraulic conductivity across the site, Quantex will select a pump(s)
that will be compatible with the EHC solution and which will maximize flow into the
formation without short-circuiting above the point of injection or unintended hydro -
fracturing of the formation. More specifically, the pump pressure will be matched to the
anticipated aquifer backpressure.
Pump(s) proposed for this project will be capable of flow rates ranging from 0.50 gpm up to
6 gpm and pressures ranging from 40 psi up to 200 psi. Pumping pressures will be
monitored at the top of the injection rod string (above grade), while flow rates will be
calculated from the time it takes to complete each injection versus total fluids injected for
each point. Quantex anticipates that either a progressive cavity pump or diaphragm pump
will be best suited for this project.
Ti
Quantex proposes to use a Geoprobe 7720DT direct push rig. This rig will be utilized to
advance all injection tooling and rod string for the specified project. At the customers'
choice, Quantex will use either a drop-off point injection system or a specially designed
hollow injection rod system that incorporates perforated openings along a 12" section of
the tool string. These openings help direct the solution laterally in a radial pattern into the
formation at a pre -determined depth. Typical tool string sizes will vary from a 1.5" O.D. up
to a 2.25" O.D. Unless otherwise directed, the injection will be performed using a "Bottom -
up" method. All tanks, hoses and fittings will be compatible with the EHC solution.
A site -specific Health and Safety Plan (HASP) will be developed in collaboration with the
client. Quantex will select personal protective equipment specific to the MSDS sheets and
information provided by Adventus. Field safety meetings will be held daily or as frequent as
needed to protect human health and promote safety during all phases of work. Quantex
will only utilize personnel that have completed 40 hour OSHA training, plus completed a
certified annual 8 hour refresher class, as applicable.
Upon completion of the injection, the tool string will be extracted and the borehole
abandoned according to State rules and regulations. The borehole opening will be repaired
to closely match existing surface conditions using like materials. Containment will be
incorporated into the injection process so as not to spill the EHC solution. Good
housekeeping practices will be implemented at all times.
If you have any questions concerning the contents of this SOP, please feel free to call on
me at your earl' st convenience.
Sincerely,
J.D. Barker

MONITOIRNG PLAN
Attachment F
Prior to the pilot test, Withers and Ravenel will conduct a groundwater sampling event
which will include existing wells 2W-2, 2W-2D, 2W-4 through 2W-6, 2W-8, MW-1
through MW-5 to establish pre injection aquifer conditions.
Subsequent pilot test activities, groundwater sampling will be conducted to monitor the
effectiveness of the injectate in reducing contaminant concentrations. Groundwater
monitoring wells 2W-5, 2W-6, MW-1, MW-2, MW-3, MW-5 will be sampled one week,
one month, two months, three months, six months, nine month and twelve months after
the pilot study.
Groundwater samples will be analyzed for the following:
• VOCs by 8260
• Chlorides by EPA method 325.2
• Carbon Dioxide by SM 45000O2D
• Methane, Ethane, and Ethene by RSK 175
All groundwater samples will be decanted into laboratory provided bottles and shipped
under the proper chain of custody.
All wells will be sampled using low flow/minimal draw down techniques. During the
purging process MNA parameters will be recorded which include pH, electrical
conductivity, dissolved oxygen, oxygen reduction potential.
