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
KSOC 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
March 5 and 27, 2009.
2.0 GROUNDWATER MONITORING ACTIVITIES
Static water levels were measured in the existing monitoring wells on -site on March 5,
2009. Groundwater samples were collected from ten of the monitoring wells (MW-7,
MW-11. MW-13, MW-13D, MW-14, MW-23D, MW-24, MW-25, MW-42. and MW-45)
and analyzed for VOCs by EPA Methods 601 and 602, isopropyl ether, methyl tert-butyl
ether, ethylene dibromide, and xylenes. In response to a letter from NCDENR
requesting that MW-14D and MW-43D be included in future monitoring events,
groundwater samples were collected from these wells on March 27, 2009. 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 March 5, 2009. The
97746 1 GS009R022 Page 1 April 17, 2009
Copyright 2009 Kleinfelder

monitoring well locations are shown on Figure 2. The static water levels measured on
March 5, 2009 between monitoring wells MW-32 and MW-45 indicate a horizontal
groundwater flow gradient of 0.04 feet per foot to the northwest. A groundwater flow
map of the shallow aquifer based on the March 5, 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 1995 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 March 5, 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 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 March 5 and 27, 2009 are summarized in Table 2, 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 the respective North
Carolina groundwater quality standards established in 15 NCAC, Subchapter 2L (2L
Standards) in each of the twelve monitoring wells sampled. The analytical results are
summarized in Table 3 and a historical summary of groundwater sampling results is
presented in Table 4. Chain -of -custody documents were maintained throughout the
97746 J GS009R022 Page 2 April 17, 2009

collection and transportation process and are included in Appendix A with the laboratory
reports.
Historical total volatile organic compound concentrations for each monitoring well
sampled are shown in individual graphs included in Appendix B. The individual graphs
of the total VCC concentration for each monitoring well indicate MW-7, MW-11, MW-
13D, MW-14, MW-14D, MW-24, MW-42, and MW-43❑ generally have trends of
decreasing contaminant levels. The graph of contaminant concentrations in MW-45
indicates the total VOCs level remains fairly consistent. Monitoring wells MW-13 and
MW-23D graphs show a recent increase; however, they have tetrachloroethene
concentrations below the laboratory detection limits. The increase in contaminant
levels in these weals is caused by increases in cis- 1,2-dichloroethene and vinyl chloride
which are degradation components of tetrachloroethene. The trend of rising
contaminant concentrations are of concern in monitoring well MW-25. Total VOCs
concentrations detected during the March 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 4 by a double line. Total chlorinated
hydrocarbons concentrations detected during the March 2009 sampling event are
shown on Figure 5. Historical chlorinated hydrocarbon contaminant levels generally
follow the decreasing trend of total VOCs in MW-7, MW-11, MW-13D, MW-14, MW-
14D, MW-24, MW-42, and MW-43D; consistent levels in MW-13, MW-23D, MW-45;
and the rising trend in MW-25.
4.0 HiSGC INSTALLATION AND MONITORING
Kleinfelder applied for a permit from the Underground Injection Control (UIC) 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.
97746 I GS009R022 Page 3 April 17, 2009
Copyright 2009 Kleinfelder

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 twenty four -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 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-23D, 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.
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 5 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
97746 1 GS009R022 Page 4 April 17. 2009
copyright 2009 Kleinfelder

remaining service life of the hydrogen cylinders. Table 6 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 June 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.

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 exist at the site. Both the total chlorinated hydrocarbons and
petroleum hydrocarbons contaminant levels in monitoring wells MW-7, MW-11, MW-
13D, MW-14, MW-24, and MW-42 have decreased when compared to the groundwater
contamination levels during the baseline sampling event in June 2008. Monitoring wells
MW-14❑ and MW-43❑ 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-13,
MW-23D and MW-45 remained consistent with the baseline levels and monitoring well
MW-25 showed an increase. Monitoring well MW-13 and MW-23D have
tetrachloroethene concentrations below the laboratory detection limits. The increase in
contaminant levels in these wells is caused by increases in cis-1,2-dichloroethene and
vinyl chloride which are degradation components of tetrachloroethene. Monitoring well
MW-25 also shows an increase in these degradation components; however, there is an
increase in tetrachloroethene as well. A comparison of total chlorinated hydrocarbons
in the ten monitoring wells sampled since the baseline sampling event in June 2008
indicate a reduction by 33 percent.

Corrective action monitoring will be conducted on a quarterly schedule and the next
event should be scheduled for June 2009. During the next sampling event, we
recommend the following wells are sampled: MW-7, MW-13, MW-13D, MW-14,
MW-14D, MW-16, MW-23D, MW-24, MW-25, MW-42, MW-43D, and MW-45. We also
recommend moving the HiSQC unit from monitoring well MW-10 to MW-25. Monthly
system checks should also be conducted during the next quarter to monitor the rate of
hydrogen consumption of the HiSOC delivery system.
Copies of this report have been mailed to the Guilford County Department of
Environmental Health in Greensboro, North Carolina and the SIC Program in Raleigh,
North Carolina.
