The site is located on the south side of Westpoint Boulevard and east of Viceroy Drive (Figure 1). Fairchild Industrial Products Company, who leases the property from Highwoods/Forsyth Partnership Limited, currently occupies the building. Trigon Engineering Consultants, Inc. (Trigon) conducted a Comprehensive Site Assessment (CSA), dated December 11, 1998, concluding that the volatile organic compounds (VOCs) tetrachloroethene or perchloroethene (PCE), trichloroethene (TCE), cis-1,2-dichloroethene (cis-1,2-DCE), and toluene were detected in soils near the source area. VOCs were detected above North Carolina Title 15A NCAC 2L groundwater standards (NCGWS) in monitoring wells MW-1, MW-2, MW-3, MW-4, and MW-6. A Corrective Action Plan (CAP) proposing the application of Hydrogen Release Compound (HRC) was prepared to address these constituents. No free product was encountered at the site during the CSA. Both Forsyth County Tax Maps and the 1950 USGS Winston-Salem West Quadrangle indicate a tributary of Salem Creek formerly crossed the western and southern portions of the site flowing to the southeast. No surface water is currently located within 500 feet of the source area. Buried water, power, and natural gas lines are located along the eastern side of Viceroy Drive running north to south. However, none of these utilities are suspected conduits of contaminant migration or vapor accumulation. The North Carolina Department of Environment and Natural Resources (NCDENR) Groundwater Section approved the CAP in May 2001. The goal of the CAP was to provide details for the remediation of PCE by assuring that known and foreseeable pathways are monitored while natural degradation occurs. The preferred remedial alternative to address soil contamination in the source area was soil vapor extraction (SVE). A SVE system was installed and operated at the site from July 2000 through June 2001. The preferred remedial alternative to address groundwater contamination was the application of HRC.

The limited well survey reconnaissance consisted of viewing the properties within 1,500 feet of the subject site and talking to available property owners. Water meters were identified at properties having public water service. Two water supply wells were identified within 1,500 feet of the source area. One of the water supply wells is actively used. The other water supply well is not actively used since the home was connected to municipal water. The approximate well locations are indicated on Figure 1. Land use in Westpoint Business Park is primarily commercial and industrial. The majority of the properties in the business park are zoned GI. Zone GI is defined as general industrial. The site is bound to the north by Westpoint Boulevard, to the east by Annapolis Drive, to the south by Sides Mobile Home Court, and to the west by Viceroy Drive. Land use surrounding the business park is primarily residential. 3.0 HRC INJECTION Trigon requested a permit from the Underground Injection Control (UIC) Program of the Division of Water Quality to inject HRC for remediation of groundwater contamination identified during the CSA. The original UIC Program permit expired September 30, 2003. The HRC application plan included taking groundwater samples prior to application of HRC to provide baseline contaminant levels, drilling injection wells, injecting seven to eleven pounds of HRC per vertical foot in each well, and conducting remedial monitoring. In August 2001, Trigon initialized the first round of HRC injection. HRC injection locations included twenty-nine injection points (IP-1 through IP-29) and six injection wells (IW-1 through IW-6) shown on Figure 2. Four injection points (IP-1 through IP-4) and six injection wells (IW-1 through IW-6) were drilled inside the facility to depths ranging between 24.5 and 35 feet below the ground surface. Seven pounds of HRC per vertical foot were placed in each borehole and injection well inside the facility. Ten injection points (IP-5 through IP-14) were drilled in the parking area downgradient of MW-6 and upgradient of MW-7 to depths of approximately 30 feet below the ground surface. Seven pounds of HRC per vertical foot was placed in each borehole. Fifteen injection points (IP-15 through IP-29) were TRIGON ENGINEERING CONSULTANTS, INC. Page 2 Mr. John Sealey, Fairchild Industrial Products Company December 30, 2004 Fairchild Industrial Products Company, Winston-Salem, North Carolina Trigon Project No. 015-04-014 drilled upgradient of the source area to depths ranging between 23 and 35 feet below the ground surface. Eleven pounds of HRC per vertical foot was placed in injection points IP-15 through IP-29. Five quarters of groundwater sampling and corrective action monitoring were completed following the injection of HRC into groundwater at the site. Following the November 2002 sampling event, Trigon recommended additional HRC application in the vicinity of MW-9, MW-10, MW-13, and MW-7. Trigon requested a second permit from the Underground Injection Control (UIC) Program of the Division of Water Quality to inject additional HRC. The new UIC Program permit remains effective through November 30, 2006. The HRC application plan included converting monitoring wells MW-6, MW-14, and MW-15 into injection wells, drilling additional injection wells, injecting seven pounds of HRC per vertical foot in each well, and conducting remedial monitoring. On March 11, 2004, Trigon mobilized to the site to begin the installation of injection wells and points. HRC injection locations included twenty-one injection points (IP-30 through IP-50), three new injection wells (IW-7, IW-8, and IW-9), and the conversion of existing monitoring wells (MW-6, MW-14, and MW-15) to injection wells (IW-10, IW-11, IW-12). The locations are shown on Figure 2. Fifteen injection points (IP-30 through IP-44) and six injection wells (IW-7 through IW-12) were drilled inside the facility to depths ranging between 25 and 35 feet below the ground surface. Seven pounds of HRC per vertical foot was placed in each borehole with the exception of IW-10 and IW-I I in which four pounds of HRC per vertical foot was placed. Six injection points (IP-45 through IP-50) were drilled in the parking area downgradient of MW-6 and upgradient of MW-7 to depths of 40.0 feet below the ground surface. Seven pounds of HRC per vertical foot was placed in each borehole. HRC injection was completed in March of 2004. Three quarters of groundwater sampling and corrective action monitoring have been completed following the second HRC injection event. 4.0 HRC MONITORING ACTIVITIES On December 9, 2004, static water levels were recorded in each of the monitoring wells on -site. Monitoring well MW-6, which had been dry since August of 2002, has been replaced with MW-6R. Groundwater samples were collected from ten monitoring wells (MW-1, MW-2, MW-3, MW-5, MW-6R, MW-7, MW-9, MW-10, MW-11, and MW-13) and analyzed for VOCs, volatile organic acids, and 1 icIGON ENGINEERING CONSULTANTS, INC.

Field parameters including dissolved oxygen, oxidation-reduction potential (ORP), pH, conductivity, 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, vertical hydraulic gradient, and plume orientation. Table 1 provides a summary of monitoring well construction details and groundwater elevations measured on December 9, 2004. Historical groundwater table elevation measurements are summarized in Table 2. The water table elevation at the site has decreased from 0.1 to 0.4 foot since September of 2004, with the exception of MW-5 which increased by 4.5 feet. The average decrease across the site was 0.3 foot. The static water levels measured on December 9, 2004 between monitoring wells MW-1 and MW-7 indicate a horizontal groundwater flow gradient of 0.03 foot per foot to the south-southeast. Static water levels measured in monitoring wells MW-1 and MW-2 indicate a vertical groundwater gradient of 0.01 foot per foot downward. A potentiometric surface map based on the December 9, 2004 groundwater elevations is shown on Figure 3. In -situ aquifer tests performed on shallow monitoring wells at the site during the CSA indicated that the surficial aquifer has an average hydraulic conductivity of 1.20 feet per day. The average groundwater velocity is estimated to be 0.14 feet per day (53 feet per year), based on the average groundwater gradient from the December 9, 2004 water level measurements and an estimated effective porosity of twenty-five percent. Groundwater samples were collected on December 9 and 10, 2004. The wells were first purged of three well volumes of water, or until dry, with a disposable polyethylene bailer. After allowing the wells to recharge, groundwater samples were collected and placed in laboratory prepared containers. The groundwater samples were maintained on ice until delivery to Pace Analytical in Huntersville, North Carolina. 5.0 GROUNDWATER ANALYTICAL RESULTS In order to assess the condition of the aquifer for degradation of contaminants found at the site, groundwater samples were collected for field analysis of temperature, pH, conductivity, dissolved oxygen, and oxidation-reduction potential. In addition, groundwater samples were collected for TRIGON ENGINEERING CONSULTANTS, INC. Page 4 Mr. John Sealey, Fairchild Industrial Products Company December 30, 2004 Fairchild Industrial Products Company, Winston-Salem, North Carolina Trigon Project No. 015-04-014 laboratory analysis of VOCs to monitor contaminant levels at the site, volatile organic acids to indicate the presence and metabolism of HRC, and inorganic compounds to monitor levels of the primary electron acceptors. Measurements were collected from groundwater samples for temperature, pH, conductivity, dissolved oxygen, and oxidation-reduction potential using field instrumentation. Results of the groundwater measurements indicate that the subsurface environment is suitable for natural attenuation at the site. The groundwater pH and oxidation-reduction potential at the site are generally within acceptable limits for biodegradation to occur. Dissolved oxygen concentrations have increased in monitoring wells MW-3, MW-6R, MW-7, MW-10, and MW-13. Conductivity is recorded for quality control and sampling consistency. The field measurements recorded on December 9, 2004 are summarized in Table 3, which includes the preferred conditions for natural biodegradation of chlorinated compounds within the groundwater plume. Groundwater samples from monitoring wells MW-1, MW-2, MW-3, MW-5, MW-6R, MW-7, MW-9, MW-10, MW-11, and MW-13 were analyzed for inorganic compounds including nitrite, total phosphorous, sulfide, dissolved manganese, nitrate, sulfate, dissolved iron, and chloride. Generally, in a pristine aquifer dissolved oxygen is used as the primary electron acceptor. After the dissolved oxygen is consumed, anaerobic microorganisms typically use additional electron acceptors in the following order of preference: nitrate, iron, sulfate, and carbon dioxide. Concentrations of inorganics indicate that a reductive pathway is possible for dechlorination of chlorinated hydrocarbons. Nitrate, iron, and sulfate do not appear to be competing as electron acceptors. Groundwater analytical results for inorganics are summarized in Table 4. Groundwater sample analytical results indicate that volatile organic acids were detected in five of the ten monitoring wells sampled on December 9 and 10, 2004. Volatile organic acids or metabolic acids, other than lactic acid, indicate the presence and metabolism of HRC. Analytical results for volatile organic acids are summarized in Table 5. Groundwater sample analytical results indicate that several VOCs were detected in the monitoring wells sampled. PCE was detected at levels exceeding the state groundwater standard in monitoring wells MW- 2, MW-6R, MW-9, MW-10, and MW-1 1. PCE concentrations in monitoring wells MW-6R and MW-11 TRIGON ENGINEERING CONSULTANTS, INC. Page 5 Mr. John Sealey, Fairchild Industrial Products Company December .30, 2004 Fairchild Industrial Products Company, Winston-Salem, North Carolina Trigon Project No. 0I5-04-014 increased slightly since the previous sampling event. A PCE isoconcentration map is shown on Figure 4. TCE was detected at levels exceeding the state groundwater standard in monitoring wells MW-6R, MW- 9, MW-10, and MW-11. Cis-1,2-DCE was detected at a level exceeding the state groundwater standard in monitoring well MW-9 and MW-13. Vinyl Chloride was detected at a level exceeding the state groundwater standard in monitoring well MW-1. A summary of historical VOC analytical results is provided in Table 6. A copy of the analytical results including the chain -of -custody form is included in Appendix A. 6.0 CONCLUSIONS AND RECOMMENDATIONS In general, the most definitive evidence of biodegradation of contaminants in groundwater is the reduction in contaminant concentrations and the presence of the constituents into which the contaminants degrade. PCE concentrations in monitoring wells MW-2, MW-5, MW-7, and MW-9 have decreased since the previous monitoring event. The presence of daughter products of dechlorination of PCE in monitoring wells MW-1, MW-2, MW-6R, MW-9, MW-10, MW-11, and MW-13 also indicates degradation is occurring. Metabolic acid concentrations in monitoring wells MW-1, MW-2, MW-9, and MW-13 indicate that HRC is influencing the subsurface environment in the vicinity of those wells. Total VOC concentrations have reduced in the center of the contaminant plume (monitoring wells MW-9 and MW-10) and in monitoring wells MW-2, MW-5, and MW-7. The total VOC concentration has remained similar to historical levels within monitoring wells MW-1 and MW-11. The total VOC concentrations in monitoring wells MW-6R and MW-II have increased slightly since the previous sampling event. Based on the results of the monitoring event, we recommend the continuation of corrective action monitoring on a quarterly schedule. The next monitoring event should be scheduled for mid -March 2005. It is our opinion that analysis of inorganics in each well will not be necessary to evaluate the effects of the corrective action in the upcoming monitoring events.
