A groundwater 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, a CAP Addendum was submitted recommending the use of passive hydrogen and oxygen injection to degrade the chlorinated and petroleum hydrocarbons in groundwater at the site. The hydrogen system was installed in June of 2008 and began operating on June 13, 2008. The baseline sampling event was conducted on June 5, 2008. As a result of contaminant levels detected in MW-47, MW-48 and MW-49, four new wells, three shallow and one deep (MW-50, MW-51, MW-52, and MW-53D), were installed between January 12 and 18, 2012. In August 2012, an additional deep well MW-54D was installed. A modified injection permit was approved by NCDENR on September 4, 2012. Injection of 3DMe in sixteen injection wells began on September 24, 2012. In November 2014, NCDENR approved flushing the sixteen injection wells with water. The injection was initiated December 23, 2014 and continued through April 2015. Each of the sixteen injection wells was supplied with 250 gallons of water to flush any remaining fatty acids from the 3DMe out of the wells. This technology works in concert with the existing groundwater recovery system and supplements the ability of the system to contain the contaminant plume within the property limits and reduce contaminant levels. In August 2015, EnviroTrac initiated passive oxygen injection in monitoring wells MW-30, MW- 31, MW-32, MW-40, and MW-41. The purpose of this report is to summarize the quarterly groundwater monitoring performed on September 16, 2015. 11.990009.00 Page 1 of 12 October 19, 2015 0 2015 EnviroTrac ah GI V ro Environraerital Services 2 RECEPTOR SURVEY The receptor survey was updated in November 2011. Various utilities were identified within 500 feet of the source area. No public or private water supply wells were identified within 0.5 mile of the site and the nearest surface water intake for the City of Greensboro public water supply is located 4.3 miles from the site. There is a stormwater pond near the northeast corner of the building. Additionally, there is a stream in the northern portion of the site. Two stormwater ponds southwest of the site were identified on the National Wetlands Inventory Map. Properties surrounding the site are industrial and have access to the city water supply system and the city sewer system. 11.990009.00 Page 2 of 12 October 19, 2015 0 2015 EnviroTrac iliac. Environmental Services 3 HYDROGEN AND OXYGEN DELIVERY SYSTEM INSTALLATION A permit was granted from the Underground Injection Control (UIC) Program within the Aquifer Protection Section of the North Carolina Department of Environment and Natural Resources (NCDENR) for the installation of a hydrogen and oxygen delivery system for remediation of contaminants in groundwater at the site. A renewed permit dated May 22, 2015, was issued for the site (Injection Well Permit W10400091) 3.1 HYDROGEN DELIVERY SYSTEM Installation of the hydrogen injection equipment was initiated 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 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-43D) on June 13, 2008. A HiSOC unit and filter was installed within each injection well. 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. Well construction information and groundwater elevations of the monitoring wells is included in Table 1. 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 11.990009.00 Page 3 of 12 October 19, 2015 0 2015 EnviroTrac Ab Environmencol Services casing. A new grounding rod was installed. The details of the HiSOC installation at MW-25 are substantially the same as described for the initial installation. On September 22, 2011, the HiSOC equipment in MW-25 was extended to the bottom of the well. The hydrogen pressure in MW-14D and MW-24 was increased from 45 pounds per square inch (psi) to 65 psi. HiSOC units installed in MW-23D and MW-29 had been working intermittently since May and June 2011, respectively. Following the completion of maintenance and testing, both units were removed in September and shipped to the manufacturer for repair. Both units were re -installed at the site on November 8, 2011. On December 29, 2011, the HiSOC equipment was removed from monitoring wells MW-23D and MW-34 and installed in monitoring wells MW-47 and MW-49. On February 15, 2013 the HiSOC equipment was removed from MW-47 and MW-49 and installed in monitoring wells MW-14 and MW-30. On February 20, 2013 the HiSOC equipment was removed from MW-29 and installed in MW-42. In December 2014 the HiSOCs in monitoring wells MW-14 and MW-25 were flooded. The HiSOCs were removed and allowed adequate time to dry out. They were tested on -site and it was determined that the HiSOCs were no longer operational. In February 2015 the two HiSOCs were replaced with alternate equipment to emit hydrogen into the groundwater. The HiSOCS were replaced with silicone tubing wrapped around approximately 4.5 feet of 0.75-inch diameter PVC pipe. The regulator was set at a pressure of 20 psi. The other portions of the installation remain the same. In August 2015 HiSOC or hydrogen diffusers were removed from monitoring wells MW-14, MW- 14D, MW-15, MW-30 and MW-42 and placed in monitoring wells MW-46, MW-47, MW-49, MW- 52 and MW-53D. Monitoring wells MW-46, MW-47, MW-49, MW-52 and MW-53D installations are substantially the same as previously described for wells with stick-up well covers with the gas cylinders placed above grade, secured to the well cover. Current HiSOC and hydrogen diffuser installation locations are shown on the figures in orange. In anaerobic bioremediation applications, the hydrogen diffusers saturate 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 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 11.990009.00 Page 4 of 12 October 19, 2015 C 2015 EnviroTrac fnvironmenral Services concentrations are estimated based on the approximate pressure at the installation depth of the hydrogen diffuser 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 diffusers 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. The hydrogen diffusers distribute dissolved hydrogen rich water throughout the screened interval of the injection well. Hydrogen rich water disperses around the well into the adjacent groundwater forming a treatment zone allowing enhanced bioremediation to degrade the target contaminants. 3.2 OXYGEN DELIVERY SYSTEM Installation of the oxygen injection equipment was initiated on August 4 through 6, 2015. The existing protective casings were removed from monitoring wells MW-31, MW-32, MW-40 and MW-41. Monitoring well MW-30 was previously set up to receive hydrogen. 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 oxygen cylinders. Six to ten inches of gravel was placed in the bottom of each casing. Excavations at MW-31 and MW-32 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 (15-inch by 24-inch PVC) were installed at MW-40 and MW-41 over the cylinder casings. The oxygen diffusers were installed at the site in five existing monitoring wells (MW-30, MW-31, MW-32, MW-40 and MW-41) on August 10, 2015. The oxygen diffuser consists of silicone tubing wrapped around approximately 4.5 feet of 0.75-inch diameter PVC pipe. Oxygen is supplied from a compressed gas cylinder with a regulator and gauge connected to the oxygen diffuser by Parflex tubing and a support cable. Four -foot grounding rods were installed and connected to the regulator assembly of the gas cylinders. Current oxygen diffuser installation locations are shown on the figures in blue. 11.990009.00 Page 5 of 12 October 19, 2015 © 2015 EnviroTrac ni AN FEE Environmental Services The oxygen injection system provides dissolved oxygen to the treatment well, typically at a concentration of 40 to 200 parts per million (ppm) depending on the immersion depth of the unit in groundwater. The dissolved oxygen 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 41 ppm of dissolved oxygen. Table 2 estimates the dissolved oxygen concentrations in each of the injection wells. These concentrations are estimated based on the approximate pressure at the installation depth of the oxygen diffuser in the injection wells. The calculation is made with the assumption that 41 ppm of oxygen is dissolved in the groundwater per atmosphere of pressure. Oxygen is infused from the diffusers into the treatment well at a typical rate of 15 standard cubic centimeters per minute or approximately 0.8 cubic feet per day. The oxygen consumption in each of the injection wells is tracked to estimate the remaining service life of the oxygen cylinders. The oxygen delivery system produces a convection current in the well to distribute dissolved oxygen throughout the screened interval. A curtain of oxygen rich water disperses around the well into the adjacent groundwater forming a treatment zone allowing enhanced bioremediation to degrade the target contaminants. 11.990009.00 Page 6 of 12 October 19, 2015 © 2015 EnviroTrac Ah Environmental Services 4 3DME INJECTION The existing injection permit was modified to include injection of 3DMe. The application detailed the amount of 3DMe solution to be injected at each well location, the construction details of each injection well and monitoring requirements. A treatment area approximately 200 feet by 25 feet was designed to extend across the groundwater plume perpendicular to the flow direction. The treatment interval was estimated to be from 20 feet to 35 feet below ground surface. Within the treatment area, 16 injection wells were installed approximately 12.5 feet apart upgradient of monitoring wells MW-46, MW-47, MWV-49 and MW-53D. The sixteen injection wells were installed to the depth of auger refusal (26.75 to 33.5 feet below ground surface). A 2-inch PVC casing was installed. The bottom fifteen feet of each well was screened with a sand filter pack placed around the screen and two feet above. The remainder of each well was backfilled with a bentonite seal above the filter pack and grout to the surface. The wells were installed in flush mounted protective covers. Well construction records submitted to the Division of Water Quality were included in the Quarterly Monitoring Report submitted on October 23, 2012. A sample of the municipal water was collected from the facility on August 30, 2012, and analyzed for volatile organic compounds (VOCs) by Standard Method 6200B. No volatile organic compounds were detected in the municipal water sample. Injection of 3,600 pounds of 3DMe in injection wells IW-1 through IW-16 was performed from September 24, 2012 to December 18, 2012. EnviroTrac obtained approval from the UIC Program to flush each of the sixteen injection wells with 250 gallons of municipal water. By flushing each well, remaining fatty acids separated from the 3DMe solution would be pushed out of the injection wells into the aquifer and allow the 3DMe to continue to break down the hydrocarbons in the groundwater. Injection began on December 23, 2014 and continued through April 2015. 11.990009.00 Page 7 of 12 October 19, 2015 0 2015 EnviroTrac ft EnV Environmericol Se7Ylces 5 GROUNDWATER MONITORING ACTIVITIES Static water levels were measured in the existing monitoring wells on -site on September 16, 2015. Groundwater samples were collected from 12 wells (MW-7, MW-12, MW-13D, MW-24, MW-25, MW-30, MW-32, MW-33, MW-40, MW-43D, MW-48, and MW-51) and were analyzed for volatile organic compounds by EPA Method 6200B. Monitoring wells MW-31, MW-34, and MW-52 were not sampled because they were dry. 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. The monitoring well locations are shown on Figure 2. Groundwater elevations in the existing monitoring wells were used to determine the groundwater flow direction and average hydraulic gradient. Table 1 provides a summary of monitoring well construction details and the groundwater elevations measured on September 16, 2015. The static water levels measured between monitoring wells MW-32 and MW-51 indicate a horizontal groundwater flow gradient of 0.04 feet per foot to the northwest. A vertical groundwater flow gradient was estimated between MW-14 and MW-14D to be 0.02 feet per foot downward. A vertical groundwater flow gradient was estimated between MW-46 and MW-53D to be 0.04 feet per foot upward. A groundwater flow map of the shallow aquifer based on the recorded groundwater elevations is presented as Figure 3. Based on data provided in the October 1996 Corrective Action Plan, the surficial aquifer has an average hydraulic conductivity of 0.086 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 16, 2015 water level measurements and an estimated effective porosity of thirty percent. Groundwater samples were collected from the monitoring wells using disposable polyethylene bailers. The wells were purged of three well volumes of water or until they were bailed dry. Groundwater samples were collected and placed in laboratory prepared containers. The samples were maintained on ice until delivered to Pace Analytical Laboratories in Huntersville, 11.990009.00 Page 8 of 12 October 19, 2015 © 2015 EnviroTrac North Carol transportatic 11.990009.00 Page 9 of 12 October 19, 2015 © 2015 EnviroTrac rT 6 GROUNDWATER ANALYTICAL RESULTS The field measurements recorded on September 16, 2015 are summarized in Table 3. Conductivity is recorded for quality control and sampling consistency. Significantly lower oxidation-reduction potential was recorded in monitoring wells MW-7, MW-24, and MW-25 which is consistent with the injection of hydrogen in these wells. Monitoring wells MW-32 and MW-40 had higher levels of dissolved oxygen consistent with the injection of oxygen in these wells. The contaminant plume consists of volatile organic compounds (VOCs) either petroleum related or chlorinated hydrocarbons. VOCs were detected at levels above the respective North Carolina groundwater quality standards established in 15A NCAC, Subchapter 2L (2L Standards) in 8 of the 12 monitoring wells sampled. The analytical results are summarized in Table 4 and a historical summary of groundwater sampling results is presented in Table 5. Hydrogen injection targets the reduction of chlorinated hydrocarbon contaminant levels in the groundwater. Oxygen injection targets the reduction of petroleum hydrocarbons. The VOCs targeted during the hydrogen and oxygen injection phases of the corrective action plan are separated in Table 4 and Table 5 by a double line. Total VOCs concentrations detected during the September 16, 2015 sampling event are shown on Figure 4 and total chlorinated hydrocarbons concentrations detected during the sampling event are shown on Figure 5. The concentrations of total VOCs, chlorinated VOCs, and total petroleum hydrocarbons for each monitoring well sampled are shown in individual graphs included in Appendix B. The graphs of chlorinated VOC concentrations have established decreasing trends or no 2L Standards violations in MW-12, MW-13D, MW-24, MW-30, MW-32, MW-33, MW-40, MW-43D, MW-48, and MW-51. The graphs of total petroleum hydrocarbons concentrations have established decreasing trends or no 2L Standards violations in MW-12, MW-13D, MW-32, MW-33, MW-40, MW-43D, MW-48, and MW-51. 11.990009.00 Page 10 of 12 October 19, 2015 © 2015 EnviroTrac ah nvi memal Services 7 CONCLUSIONS AND RECOMMENDATIONS The groundwater potentiometric map indicates that the groundwater flow direction at the site is to the northwest. Groundwater aquifer characteristics monitored during the sampling event indicate suitable conditions for natural attenuation of chlorinated and petroleum hydrocarbons exist within localized areas at the site. Daughter products of PCE and TCE are present in groundwater at the site indicating reductive dechlorination is effectively degrading chlorinated hydrocarbons. Historical chlorinated hydrocarbon contaminant levels generally follow the trends of total VOCs in the wells. A continued reduction of total chlorinated hydrocarbons as well as total VOCs has been achieved through passive hydrogen and oxygen injection. Corrective action monitoring should continue to be conducted on a quarterly schedule and the next event should be scheduled in December 2015. Monthly system checks should also be conducted during the next quarter to monitor the rate of hydrogen and oxygen consumption from the passive injection system. In accordance with the injection permit, future monitoring events will include sampling monitoring wells MW-12, MW-13D, MW-33, MW-34, MW-40, MW-48, MW-51, and MW-52. Additionally, monitoring wells MW-7, MW-16, MW-24, MW-25, MW-43D, MW-46, MW-47, MW- 49, and MW-53D will be sampled during the December 2015 monitoring event to assess contaminant levels.

It should be recognized that definition and evaluation of geologic and environmental conditions are a difficult and inexact science. Judgments leading to conclusions and recommendations are generally made with incomplete knowledge of the subsurface conditions present due to the limitations of data from field studies. Although risk can never be eliminated, more -detailed and extensive studies yield more information, which may help understand and manage the level of risk. Since detailed study and analysis involves greater expense, our clients participate in determining levels of service that provide adequate information for their purposes at acceptable levels of risk.
