1.0 INTRODUCTION
This report summarizes chemical oxidation injection activities that have been conducted at the
former Ciba Site in Charlotte, North Carolina in accordance with Underground Injection Control
(UIC) permit #WI0300129. The injection activities were conducted during 2012 and 2013 by
Key Environmental, Inc. (KEY). Injection permit 4WI0300129 was issued to American Color
and Chemical, LLC (ACC) on June 15, 2012 and is set to expire May 31, 2014. A permit
renewal application is being submitted concurrently with this evaluation report to extend the
injection period.
1.1 SITE BACKGROUND
The Site dates back to 1973 as an industrial/commercial property. Figure 1 provides a Site
Location Map. Figure 2 is a Site Plan of the current layout. The facility has undergone several
ownership changes and is currently owned and operated by Huntsman International who
manufactures surface coatings for the textile industry.
During the course of plant operations, solvents and chemical intermediates have been used in
manufacturing processes by the various owners of the facility. The solvents and intermediates
were stored in aboveground storage tanks (ASTs) that were located on the eastern portion of the
property (see Figure 2). The ASTs were removed in 1989. At the time of removal, chemical
constituents related to the tank contents were detected in soils in the vicinity of the ASTs. A soil
removal action was completed in 1990 and approximately 7000 tons of impacted soil were
excavated and transported to an approved off -site disposal facility. The primary constituents
detected in the soil included various benzene related compounds, tetrachloroethylene (PCE), and
trichloroethene (TCE). The area of the former tank farm now is part of a concrete covered storm
water collection feature. This area is located adjacent to the facility loading and unloading dock.
A number of environmental related investigations have taken place after removal of the ASTs.
These investigations identified chlorinated constituents occurring in groundwater within the
fractured crystalline bedrock aquifer (diorite/gabbro and associated saprolite) that underlies the
Site. Since May of 2008, the Site has been enrolled in the Inactive Hazardous Sites Branch
Registered Environmental Consultant (REC) Program (Site ID No. NONCD0000041) and has
since progressed to the remediation stage of the REC program.
1.2 REMEDIAL ACTION OVERVIEW
The approved remedial action remedy for the former Ciba Site consists of in situ chemical
oxidation in the former AST Area (former source area) combined with monitored natural
attenuation (NINA) of downgradient groundwater. Thus far, active remediation has consisted of
three separate injection events utilizing shallow borings and injection wells to distribute the
oxidant throughout the treatment area.
Potassium permanganate solution was utilized as the oxidant to address residual groundwater
constituent concentrations occurring in the former AST Area. The oxidant was selected based

upon the type of constituents to be remediated (chlorinated ethenes and benzenes), pilot study
results, and constituent concentration and distribution beneath the former AST area.
The effectiveness of each injection event is determined by collecting pre and post -injection
groundwater samples directly from the injection wells installed throughout the treatment area.
Long-term effectiveness of the permanganate injection is being monitored by the existing
monitoring well network established by previous investigative studies. The groundwater
monitoring well network consists of shallow and deep monitoring wells located between the
former source area and Steele Creek, a distance of approximately 1000 feet. Additionally, as
part of the monitoring program, surface water samples from Steele Creek have also been
obtained during baseline groundwater sample events.

2.0 SUMMARY OF INJECTION ACTIVITIES
The activities undertaken in support of UIC permit #W10300129 included injection well
installation, injection boring drilling and installation, multiple (three) injection events, Treatment
Zone Effectiveness (TZE) sampling, and groundwater monitoring. The following subsections
provide details for these activities that occurred during 2012-2013. The UIC permit authorized
use of twenty five injection wells. A total of 21 injection wells and four injection borings
comprised the 25 injection locations.
2.1 INJECTION WELL INSTALLATION
Injection well drilling occurred during June of 2012. A total of 15 injection wells were installed
during 2012 (IW-3 through IW-17). Previously, injection wells IW-1 (shallow zone) and IW-2
(bedrock zone), were installed in 2009 for the purposes of conducting a field pilot study
evaluating potassium permanganate performance. These wells are included in the current
injection well arrangement for remedial activities.
The shallow injection well network consisted of a total of 14 wells (IW-1 and IW-3 through IW-
15). The shallow zone addresses chemical constituents occurring within saprolite and the upper
weathered portion of bedrock. The injection well network for the deeper (bedrock) portion of the
aquifer consists of three wells: IW-2, IW-16 and IW-17.
Based on the analytical data collected from prior injections events, four additional injection wells
(SIW-01 through SIW-04) were installed along the water table interface during October of 2013
to provide additional treatment area coverage. Table 1 summarizes drilling and well construction
details for each injection well and injection boring utilized during the Remedial Action. Figure
3 provides injection well locations and identifies the treatment zone area.
The injection wells were drilled via air percussion (hammer) equipment and methods. Drilling
was supervised and the borings were logged by a KEY geologist. Drilling logs are provided as
Appendix A to this report. Upon completion of drilling, all wells were located horizontally and
vertically by a licensed North Carolina surveyor (survey pending for new wells SIW-01 through
SIW-04). Data, including northing/easting, ground elevations, and measuring point elevations
were provided from the survey.
The newly installed wells were developed by pumping and surging until a clear, turbid free
discharge was achieved. All Investigation Derived Waste (IDW) generated by the well drilling
and development activities was containerized in 55-gallon drums and disposed offsite in
accordance with applicable regulations.
2.2 INJECTION BORING INSTALLATION
Shallow borings targeting the water table interface and capillary fringe were installed using
direct push technology (DPT) on August 11, 2012. As the area has been previously investigated
during the RI, shallow soil samples were not required. A total of four injection borings were
installed as indicated on Figure 3 (G-1 through G-4). To maintain the integrity of the storm-

water basin, the borings were sealed with a cement/bentonite grout to the base of the concrete
cover upon completion of injection activities. The concrete cover was restored in accordance
with existing facility requirements. Appendix A contains Well Construction Records and
Abandonment Forms for the injection borings.
2.3 INJECTION PROCEDURE
Due to the active nature of the facility and proximity of the treatment area to the facility loading
and unloading dock, injection work was primarily conducted on weekends. In all, a total of
71,931 gallons of approximate 1% permanganate solution was injected into the subsurface. A
total of three separate injection events were conducted during 2012-2013:
• July 14, 15, 21, 22, and August 11, 2012,
• October 13, 14, and 15, 2012, and,
• October 26, 27, and 28, 2013.
Figure 4 provides the location and volume of permanganate injected into each well and borehole
during the three injection events. Appendix B contains Injection Event Records for the three
events that were previously submitted to the Division of Water Quality.
The injection process was conducted by mixing batches of permanganate solution in 1,500-
gallon polyethylene holding tanks (500 gallon tank for deep wells) and then pumping the
solution into the target wells. The solution mixing design consists of two mix tanks with a
potable water fill connection, mixer, and an injection pump delivering solution to a header
system. The header system is modular in that wells may be added or removed from the injection
process as required. A flowmeter and totalizer are installed on each header well assembly to
ensure the correct volume of injectant is added. A throttle valve (diaphragm or globe valve) is
included for each well to adjust the injection rate and pressure. Flexible hoses are used to
convey the solution from the header system to each well to allow for continued vehicle traffic in
the injection area. Each well -head is equipped with a threaded cap to provide a watertight seal
during injection.
For the shallow borings, the permanganate was pumped from the mix tanks through a portable
pump and into the borings. The oxidant was introduced into the formation through small
diameter (nominal 1" diameter) tubing perforated within the injection zone located between
seven to twelve feet below ground surface.
The quantity of permanganate solution injected during the each injection event was 29,830,
22,793, and 19,308 gallons respectively. The permanganate solution was distributed to each
targeted zone as follows:
• Capillary fringe/water table interface (geoprobe borings) — 2,140 gallons,
• Shallow groundwater — 66,719 gallons, and,
• Deep groundwater — 3,072 gallons.

The injected volume into the deep wells was short of the target for the initial injection. This is
attributed to low permeability of the deep zone due to sparse fracturing encountered in bedrock.
The injected volume into the DPT borings was also less than the target, as only four of the
borings were drilled rather than the eight proposed. There were no significant issues with the
shallow zone injection, with injection rates ranging from approximately 0.5-3.5 gallons per
minute.
2.4 TREATMENT ZONE EFFECTIVENESS SAMPLING
Treatment Zone Effectiveness (TZE) sampling was conducted prior to the initial permanganate
injection (July 2012) and on four occasions post injection (September 2012, December 2012,
February 2013, and July 2013). To date, TZE sampling has not been conducted after the last
(October 2013) injection event. The next TZE sample event will be conducted in February or
March of 2014, to allow time for the injected permanganate to attenuate from the treatment area.
Hence, the discussion of TZE sampling results (below) does not include data collected after the
last (October 2013) injection event.
TZE groundwater sampling was accomplished by use of passive diffusion sample bags installed
within the screened portion of each injection well. The diffusion bags were allowed to
equilibrate in the well for a minimum period of fourteen days prior to retrieval and submittal to a
North Carolina certified laboratory for volatile organic compounds (VOCs) analysis (EPA
Method 8260).
2.4.1 Shallow Injection Well Sample Results
Figure 5 summarizes the sample results for the TZE sampling events for the shallow zone.
The baseline (July 2012) sample results identified part per million (PPM) total concentrations of
chlorinated ethenes (tetrachloroethene, trichloroethene, cis-1,2-dichloroethene, vinyl chloride)
within the central (IW-01, IW-08, IW-11) and eastern (IW-12, IW-13, IW-14, IW-15) portions of
the treatment area. The eastern portion exhibited the highest concentrations with total
chlorinated ethene concentrations ranging from approximately 7 to over 80 PPM. Within the
south-central portion of the treatment area, total chlorinated ethene concentrations ranged from
approximately 1 up to 50 PPM. Constituent concentrations in the north -central and western
portions of the treatment area all revealed baseline total chlorinated ethene concentrations of less
than one-half PPM.
In addition to the chlorinated ethene constituents, BTEX (benzene, toluene, ethlybenzene,
xylene) and chlorinated benzene (chlorobenzene, 1,2-dichlorobenzene, 1,3-dichlorobenzene, 1.4-
dichlorobenzene, 1,2,4-trichlorobenzene) constituents were detected in the eastern and south-
central portion of the treatment area (see Figure 5). Total concentrations of these constituents
ranged from approximately 1 to 3 PPM in these areas with the exception of IW-14 where 19
PPM was detected (the concentration at this location was dominated by benzene which was
detected at 13 PPM).
The permanganate injections were found to decrease VOC constituents significantly at most
locations with several locations experiencing an initial reduction of greater than 90%. However,
2-3 KK#J6'VV"1'0NMHNT'qL
/NCORPOR -

the analytical data indicate that as the permanganate solution attenuates, an observable
constituent rebound occurs. The rebound was most evident at the easternmost injection well
locations (IW-12, IW-13, IW-14), where constituent concentrations are greatest.
For the chlorinated ethene constituents, the injection wells along the eastern boundary of the
injection area (IW-12, IW-13, and IW-14,) now reveal a total decline of about 35-50% after the
July 2013 TZE sampling event. These wells hade total chlorinated ethene concentrations greater
than 10 PPM remaining after the first two rounds of treatment.
The most recent chlorinated ethene constituent concentrations detected at the central injection
well locations (IW-7, IW-8, IW-9, IW-10) did not exhibit a measurable concentration rebound.
The chlorinated ethene concentrations at these locations remain consistent with the initial
reductions that were achieved (typically 90% or greater). The baseline concentrations at these
locations were significantly lower than the wells along the eastern boundary.
Where present (eastern and south-central portion of treatment area) the constituent rebound for
the BTEX and chlorinated benzene constituents was more pronounced than the chlorinated
ethene constituents. In particular, the easternmost injection wells (IW-12, IW-13, IW-14, and
IW-15) reveal no observable decrease from baseline conditions, based upon the latest (July 2013)
sample data.
The wells along the western injection boundary continue to exhibit non -detectable to trace
detections for all constituents.
2.4.2 Deep (Bedrock) Injection Well Sample Results
Figure 6 summarizes the sample results for the TZE sampling events for the bedrock zone.
Baseline chlorinated ethene concentrations ranged from approximately 10 to 24 PPM in the three
deep injection wells. Baseline chlorinated benzene constituents in bedrock were comparatively
low, with total concentrations all significantly less than one PPM. BTEX constituents were not
present in significant concentrations or extent in the bedrock injection locations.
Sampling results indicate that the permanganate injections were effective in constituent reduction
for both chlorinated ethenes and chlorinated benzenes, with no observable rebound effect.
Within the deep zone, after visual permanganate was no longer present, chlorinated ethene and
chlorinated benzene concentrations remain significantly reduced (mostly >90%) at all three
locations, based upon the July 2013 TZE sample results.
2.5 GROUNDWATER MONITORING WELL SAMPLING
Groundwater monitoring associated with the remedial action thus far has consisted of four
quarterly sample events for the groundwater monitoring well network identified in Table 2 plus
one semi-annual sample event for selected onsite wells (MW-16, MW-16D, MW-17, RW-01,
RW-02, PZ-02S, PZ-OZD,PZ-02E, and PZ-02F) in accordance with UIC permit requirements.

ENV/RONMENTA`"�

Interim Evaluation Report January 2014
Former Ciba-Geigy Facility
Charlotte, North Carolina
The quarterly monitoring events were conducted in July 2012, October 2012, February 2013, and
May 2013. The semi-annual UIC sampling event was conducted in December of 2013.
During the quarterly events, all wells were sampled for VOCs (EPA Method 8260) and fourteen
select locations were sampled for monitored natural attenuation parameters (MNA), as defined in
Table 3. The MNA parameters were collected to establish a baseline of water quality conditions
to evaluate future results. During the semi-annual event, the selected monitoring wells were
sampled for VOCs, potassium, and manganese (analysis for potassium and manganese was used
as a tracer to determine if the permanganate injected into the treatment areas has migrated
beyond the boundaries of the treatment area).
Figure 7 is a tag map illustrating the detections of VOCs for each sample round. Due to the
relatively short time frame since the initial injection in July of 2012, only some of the nearest
shallow monitoring wells have exhibited a decline in Site related VOCs (chlorinated ethenes and
chlorinated benzenes). These include monitoring wells MW-01, MW-16, MW-16D, MW-17,
and RW-01. Significant constituent decline is not yet evident at the monitoring wells located
further downgradient at this time owing to the groundwater velocity and travel time
considerations.
A tabulated summary of the quarterly MNA sample results is included in Appendix D. The
NINA results do not indicate any significant changes in groundwater chemistry adjacent to the
treatment zone area. Also, the potassium and manganese data collected during December 2013
for the onsite wells do not indicate that the potassium permanganate solution has migrated
beyond the boundaries of the treatment area.
The analytical data collected thus far represents the water quality conditions occurring during the
implementation of remedial activities, and coupled with the first year VOC sample results, will
provide a baseline that future sampling can be compared in order to evaluate MNA effectiveness.
2.6 ADDITIONAL ACTIVITIES
Additional activities conducted during 2013 consisted of supplemental field activities within the
treatment area to characterize the visual permanganate remaining in the injection wells and a test
boring investigation (Optimization Investigation) to determine if a recalcitrant zone of Site
related VOCs occur within the shallow subsurface of the treatment area. The supplemental field
activities confirmed that the injected permanganate was successfully distributed throughout the
treatment zone and remained in portions of the treatment zone six months after injection. The
Optimization Investigation identified two areas of elevated Site related VOC constituents within
the shallow saprolite soils of the treatment area. Appendix E and F provide details regarding
these supplemental activities, respectively.

3.0 SUMMARY
The remedial actions conducted thus far indicate that potassium permanganate has reduced
constituent concentrations within the treatment area, especially within the deep (bedrock) zone.
The constituent rebound observed in the shallow zone during the July 2013 TZE sampling
suggested that a recalcitrant zone of Site related VOCs remain within the subsurface of the
treatment area.
The potential presence of a recalcitrant zone was investigated by a test boring program in
September 2013 (Optimization Investigation) which identified two areas of elevated VOCs.
Specifically, the rebound of both the chlorinated ethene and chlorinated benzene constituents
suggest that a shallow residual mass of these constituents remains within the treatment area (after
the 1990 soil excavation). A test boring investigation conducted in October of 2013 identified
two distinct recalcitrant zones containing residual chlorinated ethenes and chlorinated benzenes
within the saprolite inside the treatment area. Injection wells SIW-01 through SIW-04 were
installed within these areas to provide focused treatment of the saprolite along the water table
interface. The "water table wells" SIW-01 through SIW-04 were utilized during the latest
injection event of October 2013. TZE sampling (including the new wells) will be conducted in
early 2014 (February/March) to determine the effectiveness of the latest injection.
Based upon the data available for this report, supplemental future injection(s) are recommended
for the treatment area. Supplemental injections should be conducted until such time that the
VOC concentrations within the treatment zone are reduced to the point that remedial goals can
be achieved at the downgradient monitoring locations through MNA.
Given the time required for attenuation of the permanganate within the treatment area, the
frequency of supplemental injection events should be no more frequent than on an annual basis.
This amount of time will permit the permanganate to attenuate, allow for post -injection sampling
of the injection locations plus evaluation of data. If required, subsequent injections will focus on
areas of potential "hot spots" that could result in a rebound of constituent concentrations within
the treatment area.
In addition to this recommendation, the following conditions were identified during
implementation of the remedial action:
• After completion of injection, visual permanganate persists within the treatment zone for
greater than six months. This observation illustrates the relatively low groundwater
velocity exhibited by the shallow zone (estimated at less than 40 feet per year).
• No visual permanganate was detected in any groundwater monitoring well during or after
injection events indicating that the permanganate solution remained within the treatment
zone prior to attenuation.
Permanganate presence is characterized by elevated potassium and manganese
concentration (Appendix E). Where visual permanganate was observed in the shallow

zone of the treatment area, potassium concentrations ranged from 150 to 500 mg/l and
manganese concentrations ranged from 72 to 190 mg/l. Baseline values for theses
parameters in the shallow zone are less than 5 mg/l for potassium and 0.5 to 3 mg/1 for
manganese.
• OPost-injeetion�1�WA M—m-glinM%thegmonitotingwelL n-etw.orlmevsealedikbaselinewalues�
for potassium and manganese during all sample events (except for a one time detection of
manganese at MW-17 during the January 2013 monitoring event).
• Permanganate injection decreased chlorinated ethene concentrations in both the shallow
and deep (bedrock) zones within the treatment area. Greater than a 90% reduction was
initially achieved in each zone after injection.
• Once the permanganate attenuated in the treatment area, a rebound of constituent
concentrations resulted in shallow zone chlorinated ethene reduction of approximately
35-50% in the easternmost injection well locations (as compared with July 2012 baseline
concentrations).
• The rebound effect was more pronounced for chlorinated benzene constituents, especially
along the eastern portion of the treatment area. Although significant reductions of these
constituents were initially observed, the chlorinated benzene concentrations for the
October 2013 TZE sample event do not indicate a net reduction from baseline
concentrations at IW-01, IW-12, IW-13, IW-14, and IW-15.
• No rebound effect was observed within the deep zone injection wells where both the
chlorinated ethene and chlorinated benzene constituent concentration reduction was
greater than 90% at all locations (except for total chlorinated benzenes at IW-16 which
revealed a 60% reduction).
• TZE sampling scheduled for February or March of 2014 will provide analytical data that
will aid in determining the effectiveness of the October 2013 injection event.

SUMMARY OF SUPPLEMENTAL FIELD ACTIVITIES

SUPPLEMENTAL TREATMENT ZONE EVALUATION SUMMARY
To confirm the distribution of potassium permanganate throughout the Treatment Zone, a field
investigation (Treatment Zone Evaluation) was conducted during the week of May 13th, 2013. The
supplemental Treatment Zone evaluation activities consisted of:
1. Checking each injection well for visual permanganate presence, and photographic
documentation of water color of fluids withdrawn from each injection well,
2. Collecting in situ field parameters (DO, ORP, pH, conductivity, turbidity) on all injection wells,
3. Collecting and analyzing samples from representative injection wells (IW-8, IW-10, IW-11, and
IW-13)for total potassium and dissolved manganese (indicators of permanganate ), and
4. Purging approximately three volumes of water from selected injection wells (IW-07, IW-09, IW-
10, IW-11, IW-13, and IW-14) to confirm the presence of permanganate in formation water
surrounding the injection points.
The supplemental activities determined that even after a period of over six months, significant
permanganate concentration remained within portions of the treatment area as evidenced by the visual
presence of purple colored water at several of the injection points. Attachment A provides a
photographic summary of groundwater extracted from each injection well.
In the shallow zone, the permanganate stained water was observed in the eastern portion of the
treatment zone resulting from downgradient migration caused by the prevailing groundwater flow
direction through the treatment zone. Accordingly, the western injection well locations exhibited an
absence of permanganate due to the eastward groundwater flow direction. Figure 1 illustrates shallow
permanganate presence (as determined by visual observation) throughout the treatment zone at
various times since the completion of the second injection event in October 2012.
Within the deep (bedrock) zone, the visual presence of permanganate was observed at two (IW-16, IW-
17) of the three injection points. This indicates the overall lack of permanganate migration due to the
low permeability encountered at the injection locations and the fact that the constituent concentration
in the bedrock zone at the injection locations was not sufficient to completely oxidize the permanganate
injected.
Table 1 summarizes stable in situ field water quality measurements obtained from each injection well
during the supplemental activities. Figure 2 provides an illustration of DO and ORP field measurements
collected at the shallow injection well points during the May 2013 supplemental activities.
Permanganate absent areas are characterized by groundwater exhibiting DO values of <1 mg/I and ORP
values of <100 mV whereas strong permanganate areas are characterized by groundwater exhibiting DO
values of >5 mg/I and ORP values of >500 mV. The areas of greatest DO and ORP readings occur in the
eastern portion of the treatment area which corresponds to the areas containing visual permanganate.
The supplemental activities also confirmed that visual observation of formation color is a good indicator
of permanganate presence and relative concentration. Based upon the analytical results from the four
injection locations (IW-8, IW-10, IW-11, IW-13) where samples for potassium and manganese were
collected, purple colored water was found to contain the greatest concentration of total potassium and
dissolved manganese when compared to dilute (pink) or clear water (see Table 2). Accordingly,
permanganate stained (purple) water was also generally found to exhibit greater concentrations of DO
and ORP levels when compared to dilute concentrations (pink) of permanganate or clear water.

The purging of select injection wells (IW-07, IW-09, IW-10, IW-11, IW-13, and IW-14) determined that
permanganate occurs within the formation water surrounding the injection points and is likely
continuous throughout much of the eastern portion of the treatment zone. Attachment B includes
photographs of groundwater samples extracted from selected injection wells, both before and after
purging. Table 3 provides a before and after summary of permanganate color at the locations that were
purged.
At six of the seven locations purged, purple colored water was observed after removing three well
volumes. This occurred even where the formation water was initially clear (one location) or where
dilute (pink) permanganate (two locations) was present. This finding supports the conclusion that
permanganate has migrated through the treatment zone from west to east due to groundwater flow
direction.

OPTIMIZATION INVESTIGATION SAMPLE RESULTS SUMMARY
A.subsurface investigation (Optimization Investigation) was undertaken within the Treatment Zone Area
b_Adentify areas: of: residual volatile organic: compounds that remain in vadose ione. or water table
interface soils after the soil excavation activities associated with tank farm removal that was conducted
in 1990.. Throughout most ofthe Treatment Zo.ne:.Area; soils were .excavated down to .a, depth. of
approximately siz feet during the soil removal activity. Thus,.the investigation primarily, targeted soils
:.
rorri beneath a. depth of six feet.
The Optimization.lnvestigation was conducted on September 4th and:5th, 2013. A.totaI of fifteen shallow
;;direct push borings were completed within the Treatment Zone as indicated on: Figure:l:.' The borings
were initially advanced five feet by' hand auger as a precaution to prevent unintended penetration of
any unidentified subsurface,utility:lines. Continuous soil sampling wasahen conducted until bedrock
refusal was encountered— Boring depths ranged from 6 to ' 18:.feet. Each boring was logged by 'a
:geologist in the field.' Boring logs for each location are included as Attachment A.
Headspace analysis utilizing'a phot6ii6nization detector (PID) .was obtained on each retrieved sample to
:provide an indication regarding the presence of VOCs. Table:1 provides a summary:of PID headspace
resultsfor the :samples collected. during the investigation. Figure 2 summarizes peak PID headspace
results:at:all boring locations.
Fifteen soil samples were selected from the ;boring locations for analysis of volatile organiic compounds
(VOCs) by EPA Method 8260B. All samples submitted for lab analysis were collected in accordance with
USEPA SW846 Method 5035 by use of .Terra. Core samplers. The, samples were submitted to Test
:America Laboratoryin. Pittsburgh, Pennsylvania:for analysis. Figure 3:summarizes constituent detections
-for the samples submitted for laboratory analysis. A summary of the laboratory analysis. reports :are
included as:Attachment B.
:The investigation: identified two areas containing Constituents of:lnterest (C01) with Part per Million
(PPM) -concentration levels in subsurface soil. These. are shown as the shaded areas on Figure. 2.:. With
the exception of the tetrachloroethene detections:at: borings 0-8 and.:&-9' the COI detections were
predominantly chlorobenienes. The eastern, shaded area also_ contains BTEX constituents. The two
areas identified will be 'addressed by focused permanganate injections during the upcoming (October
2013) injection event.
