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 currently operating at the site. The system consists of four recovery
wells, an oil -water separator, and an air stripping system.
A drastic and sudden increase in the concentration of methyl ten -butyl ether (MTBE) was detected in the
laboratory analysis of groundwater samples from MW-32 during the August 2006 sampling event.
Because of the MTBE levels detected in monitoring well MW-32, the well was resampled on November
1, 2006. Similar levels of contaminants were detected in the subsequent laboratory results. In order to
collect additional information and assess the potential origin of the MTBE, monitoring well MW-32 was
evacuated over a period of eight hours on December 7. 2006. The well was evacuated using a vacuum
truck with Aggressive F1uidNapor Recovery and twenty-four gallons of petroleum impacted
groundwater were removed. An additional groundwater sample was collected from MW-32 following
the evacuation of the well. Monitoring well MW-32 and two nearby wells (MW-7 and MW-28) were
sampled on December 14, 2006. Laboratory analytical results from the December 14, 2006 sampling
event determined MTBE levels in monitoring wells MW-7 and MW-28 were below laboratory detection
limits. The MTBE concentration From the groundwater sample collected from MW-32 on December 14,
2006 was consistent with the previous laboratory results.
In January 2008, Trigon I 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 4, 2008.

2.0 GROUNDWATER MONITORING ACTIVITIES
Static water levels were measured in the existing monitoring wells on -site on September 4, 2008.
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. 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
4, 2008. The monitoring well locations are shown on Figure 2. The static water levels measured on
September 4, 2008 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 September 4, 2008 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 surfcial 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 4, 2008,
water level measurements and an estimated effective porosity of thirty percent.
Groundwater samples were collected from monitoring wells MW-7, MW-Il, MW-13, MW-13D,
MW-14, MW-23D, MW-24, MW-25, MW-42, 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 Huntersvilie, 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 September 4, 2008 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 six of the ten monitoring
wells sampled. The analytical results are summarized in Table 3 and a historical summary of
groundwater sampling results is presented in Table 4. A chain -of -custody document was maintained
throughout the collection and transportation process and is included in Appendix A with the laboratory
report.
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 VOC concentration for
each monitoring well indicate MW-7, MW-11, MS-13, MW-13D, MW-23D, and MW-24 generally have
trends of decreasing contaminant levels. Other graphs of contaminant concentrations indicate the total
VOCs levels remain fairly consistent (MW-14, MW-42, and MW-45). The trend of rising contaminant
concentrations are of concern in monitoring well MW-25. Total VOCs concentrations detected during
the September 4, 2008 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 from the groundwater samples collected September 4, 2008 are
' shown on Figure 5.

4.0 HiSOC INSTALLATION AND MONITORING
Trigon j 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.
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-I5, 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-141), MW-15, MW-16, MW-23D, MW-24, MW-29, MW-34, and MW-43D) 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

Ms. Beth Money, Gilbarco September 26, 2008
7300 West Friendly Avenue, Greensboro, north Caoline Trigon I Kleinfelder Project No. 042-08-018
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 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 December 2008.
The HiSOC produces a convection current in the well with a designed release bubble from the top of the
HiSOC 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.
Following installation of HiSOC units in monitoring wells MW-10 and MW-29, the HiSOC units were
found to be flooded. The HiSOCs were removed and the units were dried for a period of two weeks prior
to re -installation. Otherwise the hydrogen delivery system has been in continuous operation since June
13, 2008.
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, Contaminant levels in monitoring wells MW-7, MW-11, MW-13, MW-13D, MW-23D, and
MW-24 have decreased when compared to the groundwater contamination levels during the baseline
sampling event in June 2008. Groundwater contaminant levels in monitoring wells MW-14, MW-42, and
MW-45 remained consistent with the baseline levels and monitoring well MW-25 showed an increase.
These four wells have relatively low chlorinated hydrocarbon levels and were not significantly different
than their historical averages. Groundwater aquifer characteristics monitored during the sampling event
indicate suitable conditions for biodegradation of chlorinated hydrocarbons exist at the site. Based on a
comparison of the aquifer characteristics during the baseline sampling event, the monitoring wells that

showed a significant decrease in chlorinated hydrocarbon levels (MW-7, MW-11, MW-23D, and MW-
24) also showed improved biodegradation conditions.
Corrective action monitoring will be conducted on a quarterly schedule and the next event should be
scheduled for December 2008. During the next sampling event, we recommend the following wells are
sampled: MW-7, MW-13, MW-13D, MW-14, MW-16, MW-231), MW-24, MW-25, MW-42, 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.
Copies of this report have been mailed to the Guilford County Department of Environmental Health in
Greensboro, North Carolina and the UIC Program in Raleigh, North Carolina.
