1.0 INTRODUCTION
The subject site is located at 7300 West Friendly Avenue in Greensboro, Guilford
County, North Carolina (Figure 1). There are currently two open groundwater incidents
(Incident Nos. 12960 and 15123). The incidents have a commingled plume and are
being treated with the same corrective action plan. A pump and treat system is
operating at the site, The system consists of four recovery wells, an oil -water
separator, and an air stripping system.
In January 2008, Kleinfelder submitted a CAP Addendum recommending the use of
HiSOC and iSOC technology to degrade the chlorinated and petroleum hydrocarbons in
groundwater at the site. This technology will work in concert with the existing
groundwater recovery system and supplement the ability of the system to contain the
contaminant plume within the property limits and reduce contaminant levels. The
HiSOC system was installed in June of 2008 and began operating on June 13, 2008.
The baseline sampling event was conducted on June 5, 2008. The purpose of this
report is to summarize the quarterly monitoring of the HiSOC system performed on
September 2, 2009.
2.0 GROUNDWATER MONITORING ACTIVITIES
Static water levels were measured in the existing monitoring wells on -site on September
2, 2009. Groundwater samples were collected from twelve of the monitoring wells
(MW-7, MW-11, MW-13, MW-13D, MW-14, MW-14D, MW-23D, MW-24, MW-25,
MW-42, MW-43D, and MW-45) and analyzed for VOCs by EPA Methods 601 and 602,
isopropyl ether, methyl tert-butyl ether, ethylene dibromide, and xylenes. Field
parameters including oxidation-reduction potential (ORP), pH, conductivity, dissolved
oxygen, and temperature of representative groundwater samples were also recorded
from each monitoring well sampled. Groundwater elevations in the existing monitoring
wells were used to determine the groundwater flow direction, average hydraulic
gradient, and plume orientation. Table 1 provides a summary of monitoring well
construction details and the groundwater elevations measured on September 2, 2009.
The monitoring well locations are shown on Figure 2. The static water levels measured
between monitoring wells MW-32 and MW-45 indicate a horizontal groundwater flow
977461 GS009R167 Page 1 of 6 September 30, 2009

gradient of 0.04 feet per foot to the northwest. A groundwater flow map of the shallow
aquifer based on the September 2, 2009 groundwater elevations are shown on Figure
3. Free product was not observed in any of the monitoring wells during the sampling
event.
Based on data provided in the October 1996 Corrective Action Plan, the surficial aquifer
has an average hydraulic conductivity of 0.09 feet per day. The average groundwater
velocity is estimated to be 0.01 feet per day (4 feet per year), based on the average
groundwater gradient from the September 2, 2009 water level measurements and an
estimated effective porosity of thirty percent.
Groundwater samples were collected from monitoring wells MW-7, MW-11, MW-13,
MW-13D, MW-14, MW-14D, MW-23D, MW-24, MW-25, MW-42, MW-43D, and MW-45
using disposable polyethylene bailers. The wells were purged of three well volumes of
water or until they were bailed dry. Groundwater purged from the monitoring wells was
disposed of in the on -site groundwater recovery system. Groundwater samples were
collected and placed in laboratory prepared containers. The samples were maintained
on ice until delivered to Pace Analytical Laboratories in Huntersville, North Carolina.
3.0 HiSOC INSTALLATION AND MONITORING
Kleinfelder applied for a permit from the Underground Injection Control (U1C) Program
for the installation of a hydrogen and oxygen delivery system for remediation of
contaminants in groundwater at the site. A permit dated March 20, 2008 was issued for
the site (Injection Well Permit W10400091). The permit is effective through April 30,
2010.
Installation of the injection equipment was initiated on April 9 through April 11, 2008.
The existing protective casings were removed from monitoring wells MW-7, MW-10,
MW-23D, MW-29, and MW-34. Ten -inch diameter PVC casings were installed to a
depth of five feet below ground surface adjacent to the monitoring well locations to hold
the hydrogen cylinders. Six to ten inches of gravel was placed in the bottom of each
casing. Excavations were completed for installation of 24-inch square, steel well vaults
and the vaults were set in concrete flush with the ground surface. Protective vaults
were also installed adjacent to the existing above grade protective covers for monitoring
977461 GS009R167 Page 2 of 6 September 30, 2009
Copyright 2009 Kleinfe}der

wells MW-14D, MW-15, MW-16, MW-24, and MW-43D. The 15-inch by 24-inch PVC
protective vaults were installed over the cylinder casings. Vents were installed in the
protective vaults to allow hydrogen to be released in the case of a leak from the delivery
system.
The HiSOC equipment from InVentures was installed at the site in ten existing
monitoring wells (MW-7, MW-10, MW-14D, MW-15, MW-16, MW-231D, MW-24, MW-
29, MW-34, and MW-431D) on June 13, 2008. Within each injection well is a HiSOC
unit and filter. Hydrogen is supplied from a compressed gas cylinder with a regulator
and gauge connected to the HiSOC unit by Parflex tubing and a support cable.
Four -foot grounding rods were installed and connected to the regulator assembly of the
gas cylinders. The HiSOC installation locations are shown on the figures in orange.
On May 13, 2009 the HiSOC equipment was removed from monitoring well MW-10 and
installed in monitoring well MW-25. The hydrogen cylinder was placed on the existing
concrete well pad and a protective cover was constructed around the well and above
ground protective well casing. The protective cover includes three sides and a top
made of dimensional lumber, roofing paper, and asphalt shingles. The east side of the
enclosure is open. A new grounding rod was installed. Other details of the HiSOC
installation at MW-25 are substantially the same as described for the initial installation.
In anaerobic bioremediation applications, the HiSOC supersaturates the treatment well
with dissolved hydrogen, typically at a concentration of 1 to 4 parts per million (ppm)
depending on the immersion depth of the HiSOC unit in groundwater. The dissolved
hydrogen concentration achieved in the injection well depends on the height of the
water column in the well. Each atmosphere of pressure allows for a maximum of
approximately 1.6 ppm of dissolved hydrogen. Table 2 estimates the dissolved
hydrogen concentrations in each of the injection wells. These concentrations are
estimated based on the approximate pressure at the installation depth of the HiSOC
based on the depth of the water column in the injection wells. The calculation is made
with the assumption that 1.6 ppm of hydrogen is dissolved in the groundwater per
atmosphere of pressure.
Hydrogen is infused from the HiSOC into the treatment well at a typical rate of 28
standard cubic centimeters per minute or approximately 1.4 cubic feet per day. The
hydrogen consumption in each of the injection wells is tracked to estimate the
977461 GS009R167 Page 3 of 6 September 30, 2009
Copyright 2009 Kleinfelder

remaining service life of the hydrogen cylinders. Table 3 shows the recorded hydrogen
cylinder pressures and estimates a date for each injection well that the cylinder should
be replaced. It is anticipated that the hydrogen cylinders will be replaced prior to the
next quarterly monitoring event scheduled for December 2009.
The HiSOC produces a convection current in the well with a designed release bubble
from the top of the HiSCC to distribute dissolved hydrogen rich water throughout the
screened interval. A curtain of hydrogen rich water disperses around the well into the
adjacent groundwater forming a treatment zone allowing enhanced bioremediation to
degrade the target contaminants.
4.0 GROUNDWATER ANALYTICAL RESULTS
The groundwater field analysis generally indicates that the subsurface environment is
within acceptable limits for biodegradation to occur. The field measurements recorded
on September 2, 2009 are summarized in Table 4, which includes the preferred
conditions for natural biodegradation of chlorinated compounds within the groundwater
plume. Conductivity is recorded for quality control and sampling consistency.
Volatile organic compounds were detected at levels above their respective North
Carolina groundwater quality standards established in 15 NCAC, Subchapter 2L (21-
Standards) in each of the twelve monitoring wells sampled. The analytical results are
summarized in Table 5 and a historical summary of groundwater sampling results is
presented in Table 6. Chain -of -custody documents were maintained throughout the
collection and transportation process and are included in Appendix A with the laboratory
report.
Historical total volatile organic compound concentrations and chlorinated volatile
organic compound concentrations for each monitoring well sampled are shown in
individual graphs included in Appendix B. The individual graphs of the total VOC
concentration for each monitoring well indicate MW-7, MW-13, MW-13D, MW-14, and
MW-42 generally have trends of decreasing contaminant levels. The graphs of MW-11
and MW-43D show a decrease when compared to the previous sampling event but
have previously shown increases. The graphs of MW-14D, MW-23D, and MW-24
appear to have decreasing trends; however, the most recent concentrations showed an
977461 GS009R167 Page 4 of 5 September 30, 2009
Copyright 2009 Kleinfelder

increase. The graph of contaminant concentrations in MW-25 and MW-45 indicates the
total VOCs level to be increasing. The increase in contaminant levels in monitoring
wells MW-23D, MW-24, and MW-25 is impacted by increases in cis-1,2-dichloroethene
and vinyl chloride which are degradation components of tetrachloroethene. Monitoring
well MW-24 also showed a rebound in the tetrachloroethene concentration. Total
VOCs concentrations detected during the September 2009 sampling event are shown
on Figure 4.
The current hydrogen injection phase of the corrective action plan targets the reduction
of chlorinated hydrocarbon contaminant levels in the groundwater. The oxygen
injection phase will target the reduction of petroleum hydrocarbons. The volatile
organic compounds targeted during the hydrogen and oxygen injection phases of the
corrective action plan are separated in Table 6 by a double line. Total chlorinated
hydrocarbons concentrations detected during the September 2009 sampling event are
shown on Figure 5. Historical chlorinated hydrocarbon contaminant levels generally
follow the trends of total VOCs in the wells that are sampled during this hydrogen
phase. The trend of rising tetrachloroethene contaminant concentrations has been of
concern in monitoring well MW-25. However, during this sampling event, the
tetrachloroethene concentration decreased in comparison to the previous sampling
event.
5.0 CONCLUSIONS AND RECOMMENDATIONS
The groundwater potentiometric map indicates that the groundwater flow direction at
the site is from the southeast to the northwest under a gradient of 0.04 feet per foot as
measured between MW-32 and MW-45, Groundwater aquifer characteristics
monitored during the sampling event indicate suitable conditions for biodegradation of
chlorinated hydrocarbons generally exist at the site. Both the total chlorinated
hydrocarbons and total petroleum hydrocarbons contaminant levels in monitoring wells
MW-7, MW-11, MW-13, MW-14, and MW-42 have decreased when compared to the
groundwater contamination levels during the baseline sampling event in June 2008.
Monitoring wells MW-14D and MW-43D were not sampled during the June baseline
sampling event; however, contaminant levels in both wells have decreased since their
most recent sampling in 2006. Groundwater contaminant levels in monitoring wells
MW-13D, MW-23D, MW-24, MW-25, and MW-45 showed an increase. Of these wells,
97746 l GS009R167 Page 5 of 6 September 30, 2009
Copyright 2009 Kleinfelder

only MW-25 and MW-45 show an increase in tetra chloroethene since the baseline
sampling event.
A comparison of total chlorinated hydrocarbons in the ten monitoring wells sampled
since the baseline sampling event in June 2008 and the ,June 2009 event indicated a
reduction by 52 percent. With the rebound of the tetrachloroethene concentration in
MW-24 and the degradation components in MW-23D, MW-24, and MW-25, the
September 2009 reduction in total chlorinated hydrocarbons is 35 percent.
Corrective action monitoring will be conducted on a quarterly schedule and the next
event should be scheduled in December 2009. During the next sampling event, we
recommend the following wells are sampled: MW-7, MW-13, MW-13D, MW-14,
MW-14D, MW-15, MW-23D, MW-24, MW-25, MW-42, MW-43D, and MW-45. Monthly
system checks should also be conducted during the next quarter to monitor the rate of
hydrogen consumption of the HiSOC delivery system.

Environmental Health in Greensboro, North Carolina and the UIC Program in Raleigh,
North Carolina.
