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 1SOC 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 .tune 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 June 24, 2009. 2.0 GROUNDWATER MONITORING ACTIVITIES Static water levels were measured in the existing monitoring wells on -site on June 24, 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 June 24, 2009. The monitoring well locations are shown on Figure 2. The static water levels measured on June 24, 2009 between monitoring wells MW-32 and MW-45 indicate a horizontal groundwater flow 97746 I GS009R112 Page 1 of 6 August 4, 2009 Copyright 2009 Kleinfelder KLEINFELDER 313 Gallimo;e Dairy Road, Greensboro, NC 27409 p 1336,668.0093 f 1 336.668.3868 gradient of 0.04 feet per foot to the northwest. A groundwater flow wrap of the shallow aquifer based on the June 24, 2009 groundwater elevations are shown on Figure 3. Free product was not observed in any of the monitoring wells during the sampling eve nt. 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 June 24, 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 June 24, 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 collection and transportation process and are included in Appendix A with the laboratory report. 97746 1 GSO09R112 Page 2 of 6 August 4, 2009 Copyright 2009 Kleinfelder KLEINFELDER 313 Galiimore Dairy Road, Greensboro, NC 27409 p 1336,668.0093 f 1 336k68.3868 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 individua# graphs of the total VOC concentration for each monitoring well indicate MW-7, MW-13, MW-14, MW-14D, MW-24, and MW-42 and generally have trends of decreasing contaminant levels. The graph of contaminant concentrations in MVV-45 indicates the total VOCs level remains fairly consistent. Monitoring wells MW-11, MW-13D, MW-23D, and MW-43❑ graphs show a recent increase. The increase in contaminant levels in these wells is caused by increases in cis-1,24chloroethene and vinyl chloride which are degradation components of tetra chloroethene. The trend of rising tetrachloroethene contaminant concentrations are of concern in monitoring wells MW-11 and MW-25. Total VOCs concentrations detected during the June 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 June 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-14, MW-14D, MW-24, and MW-42; consistent levels in MW-11, MW-13, MW-13D, MW-43D; and the rising trend in MW-25. 4.0 HiSOC 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 W0400091 ). 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 97746 I GS009RI 12 Page 3 of 6 August 4, 2009 Copyright 2009 Kleinfelder KLEINFELDER 313 GaMmore Dairy Road, Greensboro, NC 27409 p 1336.668,0093 f 1336,668,3868 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-231D. 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. 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 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. 97746 1 GS009R112 Page 4 of 6 August 4, 2009 Copyright 2009 Kleinfelder KLEINFELDER 313 Gallimore Dairy Road, Greensboro, NC 27409 p 1336.668.0093 f 1 336.668,3868 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 September 2009. 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. 5.0 CONCLUSIONS AND RECOMMENDATIONS The groundwater patentiometric 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 total petroleum hydrocarbons contaminant levels in monitoring wells MW-7, MW-13. MW-14, MW-23D, 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-14D 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-11 and MW-45 remained consistent with the baseline levels and monitoring wells MW-13❑ and MW-25 showed an increase. Monitoring wells MVV-11 and MW-25 show an increase in tetrachloroethene. A comparison of total chlorinated hydrocarbons in the ten monitoring wells sampled since the baseline sampling event in June 2008 indicate a reduction by 52 percent. 977461 GS009R112 Page 5 of 6 August 4, 2009 Copyright 2009 Kleinfelder KLEINFELDER 313 Gailimore Dairy Road, Greensboro, NC 27409 p 1336.668-0093 f 1336.668.3868 Corrective action monitoring will be conducted on a quarterly schedule and the next event should be scheduled for September 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 Monthly system checks should also be conducted during the next quarter to monitor the rate of hydrogen consumption of the HiSGC delivery system.
