Dear Mr. Moore: Aquifer Protection Section
The following letter report summarizes the membrane interface probe (MIP) investigation,
soil sampling, monitoring well installation, baseline groundwater sampling, and pilot test
injection activities performed at Knollwood Gulf Station at 381 Knollwood Street, Winton -
Salem, North Carolina (the site) between October 20, 2011 and October 31, 2011. A map of
the site is attached as Figure 1. This letter also summarizes the final design for activated
sodium persulfate (ASP) injection, including adjustments to the preliminary injection
quantities, intervals, and boundaries outlined in the site Corrective Action Plan (CAP) and
approved by the NCDENR Division of Water Quality (DWQ) (Injection Permit W10400198).
A statement of limitations for the conclusions of this letter report is included as
Attachment 1.
Membrane Interface Probe Investigation
Taylor, Wiseman, and Taylor (TWT) perfonned private utility location services on October
20, 2011, prior to drilling activities at the site. TWT also pre -excavated each of the planned
investigation borings using air knife and vacuum extraction equipment. On October 24, 2011,
Vironex, Incorporated (Vironex) utilized a Geoprobe* 6620 DT to advance MIP tooling at the
twelve locations illustrated on Figure 1. All MIP borings were abandoned with bentonite
following completion. MIP boring logs produced by Vironex are included in Attachment 2.
Vironex also provided cross -sectional and three-dimensional computer generated images of
the MIP investigation data, included as Attachment 3. The MIP results generally substantiate
the lateral distribution of petroleum source material suggested by previous groundwater
sample analyses, with exceptions noted near MW-6. The MIP data also suggests a narrower
vertical distribution of source material, approximately I to 17 feet below ground surface
(bgs), than the previously estimated, 10 to 20 feet bgs.
Monitoring Well Installation
Monitoring wells MW-18 and MW-19 were installed by Vironex, with oversight by Parratt
Wolff (a North Carolina licensed driller) on October 25, 2011. Monitoring well locations are

illustrated on Figure 1. The wells were completed at 20 feet bgs using 4.25-inch inner
diameter hallow stem augers. Installation of the two wells was permitted by Monitoring WeI1
Construction Permit WM0400681 (Attachment 4). Copies of Monitoring Well Construction
Records submitted to NCDENR DWQ are included in Attachment S. URS boring logs for
the wells are included in Attachment 6. Soil cuttings generated during the well installation
were containerized in 55-gallon drums and were transported off -site on October 31, 2011, by
Shamrock Environmental Corporation. A copy of the soil disposal manifest is included as
Attachment 7.
Soil Petroleum Mass, pH Buffering, and Soil Oxidant Demand Sampling
Two soil borings were advanced to 20 feet bgs by Vironex on October 25, 2011, at locations
MIP-3 and MIP-4. The locations are illustrated on Figure 1 and were selected based on MIP
results suggesting the highest petroleum concentrations. Soil samples were collected at five-
foot intervals using Geoprobel Macrocor?" acetate liners. Samples collected from the
intervals that had exhibited the highest MIP "peaks" were placed on ice and then shipped
under chain -of -custody to Accutest Southeast of Orlando, Florida (Accutest) for analysis of
total petroleum hydrocarbons (TPH) gasoline range organics (GRO) and diesel range organics
(DRO). Soil analytical results for TPH-GRO and TPH-DRO are presented on Table 1. The
laboratory analytical report for the samples is included in Attachment 8. MIP-3 and MIP-4
soil boring logs are included in Attachment 6. Both borings were abandoned with bentonite
following completion. The TPH results indicate significant petroleum mass within the
targeted area and are discussed in relation to ASP injection planning in subsequent sections.
A third Geoprobe� Macrocore* boring was completed near MW-14 at location SOD-1
(Figure 1). The SOD-] boring log is included in Attachment 6. A soil sample was collected
from between 10 and 15 feet bgs at the SOD-1 location. The boring was abandoned with
bentonite following sample collection. MW-14 was subsequently purged and sampled using a
new polyethylene bailer. The SOD-1 soil sample was submitted along with MW-14
groundwater to FMC Environmental Solutions (FMC) for soil oxidant demand (SOD)
analysis. A portion of the soil sampled from SOD-1 was stored by Vironex for subsequent
off -site pH buffering testing. SOD and pH buffering results are presented in Attachment 9.
The SOD for site soils, which is an approximate measure of the quantity of ASP that will be
consumed by natural soil constituents, is considered low as compared to most soils. However,
the pH buffering test results indicate that a relatively large quantity of sodium hydroxide
(NaOH) will he necessary to overcome natural soil acidity and maintain high pH within the
injection zone (i.e. alkaline activation).
Pilot Test Injection
Vironex performed injection of a water and NaOH solution at the site on October 26, 2011.
Injection Permit W10400198 was amended to include the NaOH solution test injection,
instead of the planned water -only test injection, through email correspondence with NCDENR
DWQ on October 5, 2011. A copy of the email correspondence is included as
Attachment 10. Approximately 70 gallons of 25% NaOH solution was diluted on -site using
approximately 1,000 gallons of fire hydrant water. A permit for use of the fire hydrant, which
is located directly adjacent to the targeted injection area. was procured from the City of
Winston-Salem and is included as Attachment 11. The diluted NaOH solution was injected at

two locations. IP-1 and IP-2, approximately five feet from monitoring wells MW-6 and MW-
8R, respectively. The IP-1 injection was performed utilizing a jetting tool injection
Geoprobe* rod attachment and the IP-2 injection was performed using a two -foot screen
injection GeoprobeA rod attachment. Water quality parameters and depth -to -water
measurement in MW-6 and MW-8R were recorded before, during, and after the injection.
Following the injections. MIP borings were advanced adjacent to the injection borings to
measure soil electric conductivity (EQ for comparison to pre -injection EC measurements.
Both injection points, as well as the subsequent MIP borings, were abandoned with bentonite
following sample collection.
A summary of the injection test procedures and results is included in Attachment 9. Positive
pilot test findings included minimum resistance to injection from the formation (i.e. low
injection pressures), clear influence from the IP-1 injection in MW-6 and subsequent EC logs,
and zero daylighting of injection material. However. in -situ pH buffering results were
inconclusive and distribution of material injected at IP-2 was not well demonstrated in
subsequent EC logs. In general, the pilot test results indicated that successful injection is
viable at the site but that distribution should be monitored during full-scale injection.
Groundwater Sampling
On October 31, 2011, groundwater levels were gauged in all site monitoring wells. including
MW-3, MW-5R, MW-6, MW-6i, MW-8R, MW-14, MW-15, MW-16, MW-17, MW-18, and
MW-19. October 2011 water level measurements are presented on Table 2 and are presented
along with historical gauging data on Table 3. A water table contour map based on the
measurements is presented on Figure 2. Figure 2 illustrates northwestern flow gradient,
consistent with historical observations.
All site monitoring wells were sampled on October 31, 2011. All monitoring wells except
MW-3 and MW-6 were purged of at least three volumes of groundwater. Monitoring wells
MW-3 and MW-6 were purged dry of groundwater and allowed sufficient time to recover
before samples were collected. Purging and sampling were conducted with new disposable
polyethylene bailers and nylon line. Groundwater pH, dissolved oxygen (DO), temperature,
oxidation-reduction potential (ORP), and specific conductance were measured using a
calibrated Yellow Springs instrument YSI-550" water quality meter. Field measurements
were measured and recorded subsequent to purging and sampling and are presented on Table
2.
Groundwater from each well was transferred to pre -labeled, laboratory -prepared containers
and promptly placed on ice with a temperature and trip blank. A duplicate sample was
collected at monitoring well MW-5R. The samples were shipped under chain -of -custody via
overnight courier to Accutest and analyzed for benzene, toluene, ethylbenzene, and xylenes
(BTEX) and methyl tert-butyl ether (MTBE) by EPA Method 6200B, sulfate by EPA Method
300, and carbon dioxide by EPA Method 4500-CO2. The analysis was performed to provide a
baseline for site groundwater concentrations prior to ASP injection in accordance with the
approved CAP and Injection Permit WI0400198. Samples collected from wells MW-5R,
MW-8R. MW-18, and MW-19 were also analyzed for TPH-GRO and TPH-DRO by SW-846
Method 8015. Groundwater analytical results are presented on Table 4. BTEX and MTBE
results are also illustrated on Figure 3 and are presented along with historical analytical data
on Table S. The laboratory analytical report for the baseline groundwater sampling event is

included in Attachment 8. Sampling, decontamination, and management of investigation
derived waste were conducted in accordance with the 2008 NCDENR UST Section
Guidelines for Sampling publication.
Final ASP Injection Plan
A summary of the final ASP injection plan is illustrated on Figure 4. The limits of Gross
Contamination Level (GCL) exceedances in groundwater estimated from previous temporary
and permanent monitoring well sampling were confirmed following installation and sampling
of MW-18 and MW-19. However, the injection area boundary was expanded slightly from the
preliminary boundary presented in the CAP to encompass elevated MIP readings near MW-6.
ASP injection quantity calculations, presented in Tables 6, 7, and 8, were adjusted from
preliminary estimates to reflect SOD testing results, pH buffering test results. and soil and
groundwater TPH analytical results. Soil sample TPH analysis has confirmed significant
petroleum mass in saturated soils in the vicinity of MW-5R and MW-8R. As a result, it is
unlikely that a single ASP injection will oxidize all petroleum present because not all
petroleum will be available (i.e. dissolved in groundwater) while the ASP is active. It is
possible that enough petroleum will be degraded so that groundwater concentrations fall
below the GCL standards, although subsequent injections may be required. The sodium
persulfate mass proposed reflects the estimated oxidant demand for petroleum in groundwater
and for natural soil organics and also incorporates a portion of the demand for petroleum in
soil to allow continued oxidation of petroleum compounds that may dissolve into groundwater
while the ASP is active.
The injection area was divided into three sections (Figure 4). The area was first divided into
the source core injection area and perimeter injection areas. A higher concentration of sodium
persulfate will be injected into the source core which encompasses the highest petroleum
concentrations at the site. The perimeter area was then divided into two areas to illustrate
variation in the planned injection intervals. The quantities of injection points for each area,
presented on Figure 4, are based on ten foot injection point spacing.
The first full-scale ASP injection event at the site is currently planned for June 2012. A
baseline groundwater sampling event, including MW-3, MW-5R, MW-8R, MW-18, and MW-
19, will be performed in May or June 2012. If you have any questions or comments about this
submittal please do not hesitate to contact me at [e-mail] or [phone].

Notes:
1.] The mobile porosity is conservatively estimated to represent soil pore volume available for injection_ A design total injection mixture volume equal to the estimated mobile pore volume is utilized to ensure that: 1.) enough pore space
is available for injection (avoid daylighting of treatment material) and 2.) the treatment media is injected into and reacts within the area targeted for treatment and is not pushed into pore space outside of the targeted area. However, the
solution volumes presented are estimates and may be adjusted based on field conditions.
2) A volume reduction factor is included to address dissolved phase contaminant displacement into surrounding groundwater_ For the source core, a factor is not included because the goal of sufficient distribution in this area is
considered paramount to injection implementation labor cost and potential temporary increases of dissolved phase concentrations in surrounding groundwater. For the perimeter areas, a factor of 2 included is included to reduce the
injected volume in half. In the perimeter areas, distribution and treatment is less essential to reaching remedial goals and implementation time cost reduction is warranted. Also, outward groundwater displacement in these areas is more
likely to impact surrounding groundwater. Note that this factor affects the dilution water volume, the total injected volume, and the mixture dilution percentage, but does not affect the mass of Persulfate injected.
3.) The vertical interval represents a weighted average of the intervals for perimeter areas A and B.
4.) Note that the dilution water includes the NaOH 25% solution.
5.) Dilution percentage = persulfate mass 1 (persulfate mass + dilution water mass). Note that for both calculations, the activator solution mass is included so that the value reflects the persulfate percentage of the total mass injected.

Statement of Limitations

Statement of Limitations
This report has been prepared based on assumptions made by URS related to data and site
characterization from previous and proposed site investigations. These assumptions, although
thought to be reasonable and appropriate, may not prove to be true in the future. Data and site
characterization utilized to develop this summary report and injection plan are restricted by the
following limitations.
Background information and other data have been furnished to URS by ARCO. NCDENR and/or
third parties, which URS has used in preparing this report. URS has relied on this information as
furnished, and is neither responsible for nor has confirmed the accuracy of this information. In
addition, it would be extremely expensive, and perhaps not possible, to perform an investigation
which would completely characterize subsurface geological conditions to ensure the detection of
all materials at the site which now are, or in the future might be, considered "contaminants" by
State or federal regulatory agencies. It is possible that any environmental investigation may fail
to reveal the presence of critical subsurface characteristics or contaminants that may be present.
URS' failure to discover hazardous materials or contaminants through reasonable and mutually
agreed -upon scopes of work does not guarantee that hazardous materials or contaminants do not
exist at the site. Finally, opinions presented herein apply to the existing and reasonably
foreseeable site conditions at the time of our assessment. Changes in the condition of this
property may occur with time due to natural processes or works of man at the site or on adjacent
properties. Changes in applicable standards may also occur as a result of legislation or the
broadening of knowledge. Accordingly, the findings of this report may be invalidated, wholly or
in part, by changes beyond our control.
No expressed or implied representation or warranty is included or intended in our reports except
that our services were performed, within the limits prescribed by our clients, with the customary
thoroughness and competence of our profession.

Project Summary
Project Name: BP 24163
Project Dates: October 24 and 25, 2011
Equipment/Manpower: Vironex mobilized one (1) custom Membrane Interface Probe (MIP) System,
one direct push technology unit, and two team members to the project site.
Contaminant(s) of Concern: Volatile ❑rganic Compounds
Project Summary: Vironex advanced 12 direct push MIP borings from the ground surface to between
approximately 12 and 21 feet below ground surface (bgs). Each boring location was airknifed from
ground surface to 6.5 feet bgs prior to advancing MIP tooling. For the purposes of this project, the MIP
system was equipped with a halogen specific detector (XSD), electron capture detector (ECD),
photo -ionization detector (PID), and flame -ionization detector (FID). During the advancement of each
boring, the response of each detector, relative to depth, was recorded in accordance with the standard
operating procedures for the MIP system. Additionally, the electrical conductivity of soil, relative to
depth, was collected during each MIP boring to provide a relative indication of soil types across the
boring interval. The MIP boring logs are provided in Appendix A. Notes related to specifics of each
individual MIP boring are provided in Appendix B. Additional information regarding the principals and
procedures associated with the MIP system is presented in Appendix C.
Quality Assurance/Quality Control: In order to maintain quality assurance and quality control standards
during the course of the project, a response test was completed before and after each MIP boring
(additional details regarding response testing are provided in Appendix Q. The response test indicates
that the MIP system is operating properly, and therefore, may be advanced into the subsurface. All
response testing conducted during the project were within the applicable Geoprobe guidelines.
Additionally, the internal carrier gas pressure of the system and MIP temperature were monitored
during the advancement of each MIP boring to ensure the system was functioning properly.

Appendix C - MIP System overview
The MIP is a direct push tool that produces continuous chemical and physical logs of the vadose and
saturated zones. It locates VOCs in -situ and shows you where they occur relative to the geologic and
hydrologic units. Vertical profiles, transects, 3D pictures and maps can all be produced from the
electronic data generated by the MIP logs. its unique capability of providing reliable, real-time
information allows you to make better and timely decisions while your team is still in the field.
The MIP is a downhole tool that heats the soils and Cori"
groundwater adjacent to the probe to 120 degrees C. This (►rwiAr
increases volatility and the vapor phase diffuses across a ("I`b`)
membrane into a closed, inert gas loop that carries these
vapors to a series of detectors housed at the surface.
Continuous chemical logs or profiles are generated from each
hole. Soil conductivity is also measured and these logs can be
compared to the chemical logs to better understand where the
VOCs occur. The MIP technology is only appropriate for volatile
organic compounds (VOCs). The gas stream can be analyzed
with multiple detectors, for example an electron capture
detector is used to detect chlorinated solvents, a photo -
ionization detector is used to detect petroleum hydrocarbons,
and a flame ionization detector is used to detect methane.

Detector Overview
• ECD - Electron Capture Detector uses a radioactive Beta emitter (electrons) to ionize some of
the carrier gas and produce a current between a biased pair of electrodes. When organic
molecules contain electronegative functional groups, such as halogens, phosphorous, and
nitro groups pass by the detector, they capture some of the electrons and reduce the current
measured between the electrodes.
• XSD - The Halogen Specific Detector converts compounds containing halogens to their
oxidation products and fee halogen atoms by oxidative pyrolysis. These halogen atoms are
adsorbed onto the activated platinum surface of the detector probe assembly resulting in an
increase thermionic emission. This emission current provides a corresponding voltage that is
measured via an electrometer circuit in the detector controller.
URS - BP 24163 - Winston-Salem, North Carolina

IIRON�x
Search and Destroy@
• PID — Photo ionization Detector sample stream flows through the detector's reaction chamber
where it is continuously irradiated with high energy ultraviolet light. When compounds are
present that have a lower ionization potential than that of the irradiation energy (10.2
electron volts with standard lamp) they are ionized. The ions formed are collected in an
electrical field, producing an ion current that is proportional to compound concentration. The
ion current is amplified and output by the gas chromatog raph's electrometer.
• FID — Flame Ionization Detector consists of a hydrogen / air flame and a collector plate. The
effluent from the GC (trunkline) passes through the flame, which breaks down organic
molecules and produces ions. The ions are collected on a biased electrode and produce an
electric signal.
MIP Data Collected
• Depth - Data is collected from twenty data points per foot. 0.05', 0.10', 0.15% etc...
• Electrical Conductivity - Electrical Conductivity data is measured/collected in milli -siemens per
Meter (ms/M). The conductivity of soils is different for each type of media. Finer grained
sediments, such as silts ❑r clays, will have a higher EC signal. While coarser grained sediments,
sands and gravel, will have a lower EC signal. The coarser grained sediments will allow the
migration of contaminants and the finer grained sediments will trap the contaminant.
• Speed I Advancement Rate - Speed data is measured/collected in feet per minute (ft/min).
Speed is an indication of the physical advancement rate of the MIP probe. Speed of the MIP
probe can vary due to operator advancement and dense sail types. Speed log can provide soil
type information which can be correlated with electrical conductivity. Lower advancement
speed, correlated with lower conductivity or larger grained soils would more than likely be
associated with dense or compacted sands.
• Temperature - Temperature data is measured/collected in Degrees Celsius. Temperature is an
indication of the physical temperature of the MIP block. Minimum and Maximum temperature
is collected at each vertical interval. Vironex's temperature protocol indicates that the MIP
probe temperature shall maintain a minimum temperature of 75 Degrees Celsius.
• Pressure - Pressure data is measured/collected in PSI. Pressure is an indication of the internal
pressure of the nitrogen lines located within the trunkline and the pressure behind the
membrane. Minimum and Maximum temperature is collected at each vertical interval.
Geoprobes temperature protocol indicates that the MIP probe pressure shall not exceed 1.5
PSI difference from baseline.
• Detector (XSD. ECG, PID, FID) - Detector responses are measured/collected in micro Volts (uV).
Detector responses are an indication of relative contaminant responses. Minimum and
Maximum detector responses are collected at each vertical interval.
Response Testing
Response testing is an integral part of ensuring the quality of data from the MIP system. Response
testing must be conducted before and after each log, This will ensure the validity of the data and the
integrity of the system. Response testing also provides for comparison of data far later MIP logs at the
same site. However, results of the response test may change due to membrane wear from soil contact
and abrasion.
Prior to conducting a response test, a response test standard solution is prepared by adding an
appropriate volume of stock standard solution to 0.5 liters of clean water in a suitable measuring
container (beaker or graduated cylinder) to produce a working standard, for example, 10 uL of 50
URS — BP 24163 — Winston-Salem, North Carolina

i>�oNl�x
Search and Destroy®
mg/mL concentration stock standard is added to 0.5 liters of water to yield a 1mg/L working standard.
Generally, response test standard solutions are prepared using trichloroethene and toluene. However,
response test standard solutions may be prepared based on the specific contaminants of concern at a
site of necessary. Also prior to conducting the response test, the MIP is placed in clean water until
detector response stabilization has occurred.
The working standard is poured into a 2-inch diameter by 30-inch long PVC or stainless steel pipe that is
capped at one end. A stabilized MIP is inserted in the working standard for a duration of 30 seconds
(Note: in the response test shown below, the MIP was inserted into the working standard for a duration
of 45 seconds), At the end of 30 seconds the MIP is removed from the working standard, and placed into
dean water. The working standard cannot be reused after a response test.
The results of the response test are shown on the MIP data acquisition unit (shown below). The trip time
is measured by recording the time between the moment when the MIP is placed in the working
standard solution and the response of the detectors, as viewed on the MIP data acquisition unit. The
baseline and peak response value are also recorded for comparison with other MIP response tests. The
trip time is entered manually into the data acquisition system account for the time it takes for
compounds in the subsurface to travel the length of the trunkline during the MIP boring.

Summary of Data Visiulization
This section presents the assumptions and settings used to develop detector models.
Kri in
Kriging is a weighted moving average interpolation (extrapolation) method that minimizes the estimated variance of a predicted
point (node) with the weighted average of its neighbors. The weighting factors and the variance are calculated using a
semivariogram model that describes the differences versus distance for pairs of samples in the input dataset. Kriging method
developed by CTECH (www.ctech.com) using EVS Pro.

Notes
1) Coordinates provided by URS.
2) MIP data was averaged over a 0.25' interval. (i.e. Data was averaged from 0.00' to 0.25')
3) If depth is labeled under EC, ECD, PID or FID then a problem occurred with the detector at that depth. When model is
kriged it is identified as unknown, not affecting data interpolation/development of the detector model (11/25/2011).

Section 3-A
PID 3-Dimensional Model

Azimuth (az) angle is the compass bearing, relative to true (geographic) north, of a point on the horizon directly beneath an observed
object. The horizon is defined as a huge, imaginary circle centered on the observer, equidistant from the zenith (point straight
overhead) and the nadir (point exactly opposite the zenith). As seen from above the observer, compass bearings are measured
clockwise in degrees from north. Azimuth angles can thus range from 0 degrees (north) through 90 (east), 180 (south), 270 (west), and
up to 360 (north again).
The elevation (el) angle, also called the altitude, of an observed object is determined by first finding the compass bearing on the
horizon relative to true north, and then measuring the angle between that point and the object, from the reference frame of the
observer. Elevation angles for objects above the horizon range from 0 (on the horizon) up to 90 degrees (at the zenith). Sometimes the
range of the elevation coordinate is extended downward from the horizon to -90 degrees (the nadir). This is useful when the observer
is located at some distance above the surface, such as in an aircraft.

Summary of Membrane Interface Probe (MIP) Investieation
-Vironex mobilized the MIP System to the subject site on October 24, 2011 to provide additional
delineation of the source area. Vironex advanced the MIP unit at twelve locations to approximately 20
ft bgs (18.50-22.35 ft bgs) and one location (MIP-10) to 12.20 ft bgs (shallow refusal). This information
was utilized to develop the ISCO remediation approach proposed herein. The full MIP investigation
report was provided November 251h under separate cover.
-The MIP data was utilized to develop 3-Dimensional (31D) images using EVS1. The images utilized to
develop the injection strategy are included below. The images below reflect the PID responses (>1e7µV)
that most closely matched with the 5 ppm Benzene groundwater isoconcentration contour line.

Summary of Injection Pilot Test and Laboratory Test Data
-Vironex performed an injection pilot test on October 26'h, 2011. The goals of the pilot test were to
determine the key parameters of injection flow rate and pressure, determine if the formation could
accept the projected full scale injection volumes, determine radius of influence and pH buffering
capacity of the soil and groundwater. The pilot test injection fog is provided in Appendix A. A summary
of the field data collected is provided in Appendix B.
-Vironex attempted two different injection tools, a top -down jetting tool (IP1) and a top -down 2 ft
screen (IP2), in order to determine the optimal distribution approach. A hydracell pump was utilized to
inject a total of 1,040 gallons of a diluted 25% sodium hydroxide (NaOH) solution. NaOH was selected in
order to track the distribution in the subsurface as well as determine the pH buffering capacity of the
soil and groundwater, The planned injection zone spanned from 10-20 ft bgs.
Injection Point 1 Summary:
-A line pressure test was first performed and it was determined that at the projected injection
flow rates of 1-2 gpm, 5-10 psi of pressure was lost from the injection manifold pressure gauge
to the injection tool.
-Maximum and sustained injection pressure ranged from 5-30 psi and 5-10 psi respectively.
Injection flow rates were consistently 1.5-2.0 gpm. Daylighting of the reagent was not observed,
although the water level in MW-6 rose approximately 4 ft.
-During the 11:34 am sampling round, a pH of 13.7 was observed in well MW-6 which was
located approximately 5 ft from IP-1. It was concluded that the NaOH had found a preferential
conduit to the well based on the pH of the well (approximate pH of diluted NaOH solution)
-The injection location was terminated at 18 ft bgs and the remaining NaOH volume 1114 gal)
was added to IP2 since no elevated pH response was observed in well MW-SR (observation well
for IP2). This was done in an attempt to increase the ROI at IP2. Please see IP-2 summary below
for more detail.
-Injection Point 2 Summary:
-Similar to IP-1, a line pressure test was first performed and it was determined that at the
projected injection flow rates of 1-2 gpm, 5-10 psi of pressure was lost from the injection
manifold pressure gauge to the injection tool. Maximum and sustained injection pressure
ranged from 5-20 psi and 5-10 psi respectively. Injection flow rates were 2.0-3.0 gpm.
Daylighting of the reagent was not observed. The water level in MW-SR rose approximately 1.6
ft. IP-2 was located S ft from MW-8R.
-The injection location was terminated at 18 ft bgs and the excess NaOH volume (114 gal) from
IP-1 was added to the 16-18 ft interval since, at the time, no significant elevated pH response
was observed in well MW-8R. This decision was made in order to increase the volume in the 16-
18 ft injection zone (thereby increasing distribution) in an attempt to influence well MW-8R. At
the conclusion of the test, a minimal increase in pH was observed (4.4 => 5.0, note that the pH
of 5.99 observed at 3:06 pm is considered an error).

-Electrical Conductivity Profiling Summary:
-Electrical Conductivity (EC) was utilized in an attempt to determine the distribution of the
NaOH injected in IP1 and IP2. In the presence of NaOH, the EC will be elevated over baseline
and provide information on the distribution of the reagent in the subsurface. Baseline versus
post injection EC logs are provided in Appendix C.
-It is apparent after reviewing the EC logs for IP-1 that the NaOH preferentially traveled to well
MW-6 (evidenced by EC spike at 11-16 ft bgs(. This EC test point was approximately 3 ft from
the injection location.
-The EC logs for IP2 were much less conclusive. Although there is an increase shallower than 11
ft bgs (above the groundwater table), there is little to no evidence of NaOH distribution in any of
the three EC locations below the ground water table. The likely reason for this is that the fluid
took a preferential path. Due to the need to hand auger all locations to 6.5 ft bgs, it was
impractical to add additional EC locations.
-Vironex intends to bring the EC unit back for the full scale event and profile the subsurface after
the activated persulfate injections have started to verify vertical distribution based on EC
increases over baseline.
-Soil Oxidant Demand:
-A background sample of soil and groundwater was sent to FMC in order to perform a Soil
Oxidant Demand (SOD ) test. A maximum value of 0.54 g/kg was determined, indicated a low
natural (natural organic matter and dissolved metals) demand. The report from FMC is included
in Appendix D.
-Buffering Demand Test Summary:
-Since the soil buffering capacity of the soil could not be determined in the field, Vironex
performed a bench scale buffering test. Fallowing FMC's guidelines, a 250 g aliquot of a 3:1
(w/w) water to soil ratio slurry was titrated with 25°% (w/w) NaOH over time to determine the
volume necessary to keep the slurry above pH 11. The data from the bench test is presented
below in Table 1. Vironex recommends a 1.0 mL 25% NaOH/62.5 g soil buffering ratio based on
this data. This value should be conservative given that the bench test provided complete mixing
of the NaOH and soil slurry.

Remediation Approach and 5trateev
-The remediation strategy for this site is source reduction through chemical oxidation with activated
sodium persulfate jASP). The goal of the project is to reduce the Benzene concentrations below 5,000
ppb in all groundwater wells in the treatment area.
-Vironex will inject ASP in the treatment area defined in Figure 4. This treatment area was determined
after reviewing the most current groundwater data and the MIP survey results. The injection intervals
were determined from existing site information and the MIP data that was collected.

Table 2. Summary of Assumptions
Assumption
Design Basis
Injection Tool/Configuration
Vironex recommends the use of the 2 ft top down injection tool and pre -strung
injection hose. This tool provided a much more consistent pressure vs flow
profile vs depth.
Injection Flow Rate
Based on the pilot injection event, 2-3 gpm can be sustained at low pressure at
each injection location. Vironex intends to manifold to 4 simultaneous locations.
Injection Pressure
Vironex anticipates that the injection pressures will be similar to those in the
pilot test (IP2), 5-20 psi (manifold pressure).
ROI
5 ft has been assumed since this could not be verified in the Pilot test. Vironex
will bring the EC unit to the full scale event and monitor vertical distribution at
the beginning of the full scale event

■ Vironex typically begins work within 34 days of authorization to proceed assuming all regulatory approvals are
in place.
■ Circumstances encountered during the performance of these services could warrant additional time or
expense; e.g. lower injection rates and/or higher pressures, reagent surfacing, regulatory delays, adverse
weather resulting in equipment freezing or overheating, muddy conditions, accumulation of rain water,
lighting, client imposed injection restrictions (low pressure) or downtime, and delays due to reagent delivery 1
or pickup for reagents purchased by client. We will notify you of any such circumstances that could affect
completion or costs of the engagement.

I. Background
FMC Corporation
Tonawanda, NY
November 15, 2011
K L O Z U R
Klozur activated persulfate is a strong oxidant capable of mineralizing a
wide range of contaminants, including chlorinated solvents, petroleum
hydrocarbons, polyaromatic hydrocarbons, gasoline additives, pesticides, and
many others. Activation of the persulfate anion generates the sulfate radical, the
primary species that drives the rapid destruction of the contaminants of concern.
Activation can be accomplished by several methods': heat, transition metals,
addition of hydrogen peroxide, or utilizing high pH. Choice of the activation
method will depend on the contaminant of concern and site characteristics.
A chemical oxidant is not specific as to what it will oxidize. As a result,
activated persulfate will not only mineralize the contaminant of concern, but a
portion of the oxidant will be used in oxidizing soil organics, reduced metals, and
organic species that are not of concern. In addition, activated persulfate will
undergo auto -decomposition, which will be a function of temperature,
concentration and activation method. The demand upon the activated persulfate
from all of these components is captured in a coarse screening test termed,
"Klozur Demand Test". It is dependent upon the site characteristics, such as the
organic content of the soil, the mineral loading, and soil type and collectively
must be considered for estimating the magnitude of oxidant dosing during field
application.
The Klozur Persulfate KDT test measures the loss of persulfate in the
presence of soil, groundwater and activator over a period of 48 and 96 hours.
The resulting KDT values can then be used as a guide to develop appropriate
persulfate dosing for subsequent treatability testing and field applications.

chemistries

II. Sample Handling for Vironex, Inc.
Client Sample Identification
■ Soil ID SOD- 1; GVV ID: MVV-14
Handling Procedures
■ The samples were received on 10/31 /2011,
• During the collection of the preliminary data, the soil was well mixed, used
and returned to a new container after its use.
• The groundwater sample was well mixed, used and returned to the
original container after its use.
• On 11/07/2011, multiple experimental samples were prepared according
to the amounts shown in the results table below.
+ The experimental samples were stored at room temperature and each
sample was vigorously shaken once per day.
• About 200 grams of the soil sample are left with us and about 1.5 liters of
groundwater sample is left. The unused soil and groundwater samples will
be disposed of responsibly after about one week.

IV. Conclusions
The Klozurg) Persulfate demand with NaOH activation for the Soil Sample
SOD-1 and Groundwater Sample MW-14 ranges from approximately 0.48 — 0.54
g persulfate 1 kg soil, which is considered low as compared to persulfate SOD for
most soils.
Based on these values, an average of 0.51 g 1 kg should be used as a
site -wide SOD for further refinement of the Klozur persulfate total demand.

FMC Customer Representative
Note: 1. FMC recommends performing suitable treatability testing and field pilot demonstration to
determine the effectiveness of Klozur activated persulfate on the contaminants of concern. KDT
testing provides only an indication of the minimum amount of oxidant required to overcome the
demands of soil, groundwater and other secondary species that contribute to the usage of the
oxidant. The KDT results do not imply a guarantee of efficacy of the activated persulfate in actual
field situations. 2. ANY SUCH QUANTITY OR WARRANTY IS EXPRESSLY DISCLAIMED.

I have considered the situation and have been in contact with our Winston-Salem Regional Office
regarding your request to "consolidate" the injection activities for the subject permit.
We have no objection to your proposed activities, as described in your email message of October 3,
2011. Please contact either myself or Ms. Wang of the Winston-Salem Regional Office if you have
any further questions or concerns.
Thank you for notifying us.

Mr. Goodrich,
We will be performing the pre -injection investigation and baseline monitoring, as described in the
permit application, between October 20, 2011 and November 1, 2011 at the site.
In the application we had indicated that pre -injection investigation would include aquifer testing,
which would be accomplished by injecting water in two locations to help plan for Subsequently
injecting NaOH and persulfate, and would include laboratory testing to determine site soil NaOH
buffering capacity. We would like to instead combine these tests by injecting the 25% NaOH
solution during testing and monitoring surrounding pH to test soil buffering capacity in -situ. This
will allow us to more accurately determine the amount of NaOH activator needed for persulfate
injection to support a more effective remediation event. We will be sampling all site groundwater
monitoring wells and measuring pH in all monitoring wells the week following the injection testing.
Please indicate approval of this small adjustment to the application information.
