The site is located on the south side of Westpoint Boulevard and east of Viceroy Drive (Figure 1). Fairchild Industrial Products Company occupies the building. Kleinfelder (previously Trigon Engineering Consultants, Inc.) conducted a Comprehensive Site Assessment (CSA), dated December 11, 1998, which concluded 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. The North Carolina Department of Environment and Natural Resources (NCDENR) Groundwater Section approved the Corrective Action Plan (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. An Administrative Agreement with the REC Program was executed March 3, 2009. A survey of the property was conducted in June 2009. A copy of the survey is included as Figure 2. 2.0 RECEPTOR SURVEY On September 29, 1998, Kleinfelder completed a limited well survey of the site area. 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 97626 1 GS011 R079 Page 1 of 9 May 24, 2011 Copyright 2011 Kleinfelder 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. In November 2005, Kleinfelder updated the well survey by conducting a field reconnaissance of properties and by mailing letters to the property owners within 500 feet downgradient of the site. Letters were sent to five property owners by registered mail. No water supply wells were identified within 500 feet of the site and no new water wells were identified within 1,500 feet of the site. 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. On October 14, 2009, a survey was completed to include areas within 0.5 miles of the release. The areas within 0.5 miles north and east of the site generally include industrial properties. Fire hydrants and water meters were observed in these areas. No water supply wells were observed. The areas within 0.5 miles south and west of the site include residential and industrial properties. This area is on the southern edge of the City of Winston-Salem limits. The properties on the north side of West Clemmonsville Road were annexed by the City of Winston-Salem in September of 2006. According to the Forsyth County GIS, many of the residences consist of homes built more than 30 years ago. Fire hydrants and water meters were observed in the area as well as several water supply wells. Due to the age of the residences and being on the outskirts of the city limits, the properties are likely to have water supply wells. Figure 3 shows the location of the wells observed during the surveys. Several small ponds were also observed in the area and can be seen in the aerial photograph (Figure 3). Water wells identified during the receptor survey are not anticipated to be impacted by the release at the site. 97626 1 GS011 R079 Page 2 of 9 May 24, 2011 Copyright 2011 Kleinfelder 3.0 HRC INJECTION Kleinfelder 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 collecting 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, Kleinfelder initiated 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 4. 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 35.0 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 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 were 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, Kleinfelder recommended additional HRC application in the vicinity of MW-7, MW-9, MW-10, and MW-13. Kleinfelder requested a second permit from the Underground Injection Control (UIC) Program of the Division of Water Quality to inject additional HRC. The second UIC Program permit was effective through November 30, 2006. This 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, Kleinfelder mobilized to the site to begin the installation of the additional injection wells and points. HRC injection locations included twenty-one 97626 1 GS011 R079 Page 3 of 9 May 24, 2011 Copyright 2011 Kleinfelder injection points (IP-30 through IP-50), three new injection wells (IW-7, IW-8, and IW-9), and the conversion of three existing monitoring wells (MW-6, MW-14, and MW-15) to injection wells (IW-10, IW-11, IW-12). 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-11 in which four pounds of HRC per vertical foot were 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 were placed in each borehole. The injection locations are shown on Figure 4. HRC injection was completed in March of 2004. On May 30, 2007, Kleinfelder mobilized to the site to begin the installation of the additional injection wells, IW-13 and IW-14. Injection well IW-13 was drilled northwest of monitoring well MW-11 and injection well IW-14 was drilled northwest of monitoring well MW-9. The injection well locations are shown on Figure 4. Monitoring wells DW-17 and DW-18 were also converted to injection wells IW-15 and IW-16, respectively. Between May 17, 2007 and June 26, 2007, approximately thirty pounds of HRC was placed in each of the injection wells with the exception of injection wells IW-1, IW-2, and IW-3. Three hundred pounds of HRC, approximately twenty-five pounds per injection well, was placed in the injection wells on December 18, 2007; March 4, 2008; September 3, 2008; and March 4, 2009. Kleinfelder submitted a request to modify and renew the UIC Program permit. The request included augmenting the injection well system in the vicinity of MW-9 and MW-11, injecting additional HRC, and conducting remedial monitoring. In order to further accelerate the process of natural attenuation, Kleinfelder submitted an application to the UIC Program on June 21, 2010 to modify and renew the existing injection permit to allow for injection of an additional hydrogen generating compound. The Regenesis product, 3-D MicroEmulsion (3DMe), incorporates Hydrogen Release Compound (HRC) Advanced and is designed to time release highly efficient electron donors. The 3DMe product is designed to have a greater longevity. Application of the 3DMe as an emulsified suspension in water will allow for a greater radius of influence during injection. The radius of influence will increase over time as the soluble components of 3DMe are distributed within the aquifer by advection and diffusion. A 97626 1 GSO11 R079 Page 4 of 9 May 24, 2011 Copyright 2011 Kleinfelder permit was issued by the UIC Program on June 30, 2010 and is effective until May 31, 2012. On September 7, 2010 Kleinfelder mobilized to the site and began placing 3DMe into fifteen of the injection wells. For each injection well, 3DMe was mixed with water at a one to ten ratio in a 250 or 350 gallon water tote with a submersible pump continually mixing the 3DMe and water solution throughout the injection process. Once the one to ten solution drained into the injection wells an additional 200 to 360 gallons of water was placed into each injection well. Between September 7, 2010 and October 8, 2010, a total 304 gallons of 3DMe and 6,739 gallons of water were injected into the injection wells. The injection well locations are shown on Figure 4. 4.0 HRC MONITORING ACTIVITIES Static water levels were recorded in all of the monitoring wells on April 15, 2011. Table 1 provides a summary of monitoring well construction details and the groundwater elevations measured on April 15, 2011. Historical average groundwater elevation measurements are summarized on Figure 5. Groundwater elevations in the existing monitoring wells were used to determine the groundwater flow direction, average hydraulic gradient, vertical hydraulic gradient, and plume orientation. Groundwater samples were collected from twelve monitoring wells (MW-1, DW-2, MW-5, MW-6R, MW-7, MW-8, MW-9, MW-10, MW-11, MW-13, DW-16, and DW-19) and analyzed for VOCs by EPA Method 6200B. Additionally, monitoring wells DW-2, MW-6R, MW-9, MW-10, MW-11, MW-13, DW-16, and DW-19 were sampled and analyzed for metabolic acids. Groundwater samples were collected using low flow sampling procedures from the monitoring wells. The wells were first purged of one to two well volumes of water, until field parameters stabilized, at a low flow rate with a peristaltic pump. Groundwater samples were collected and placed in laboratory prepared containers. The groundwater samples were maintained on ice until delivered to Pace Analytical in Huntersville, North Carolina. Field parameters including oxidation-reduction potential (ORP), conductivity, pH, dissolved oxygen (DO), and temperature of representative groundwater samples were also recorded from each monitoring well sampled (Table 2). 97626 1 GS011 R079 Page 5 of 9 May 24, 2011 Copyright 2011 Kleinfelder The static water levels measured on April 15, 2011 between monitoring wells MW-3 and MW-7 indicate a horizontal groundwater flow gradient of 0.03 feet per foot to the southeast. A groundwater flow map of the shallow aquifer based on the April 15, 2011 groundwater elevations are shown on Figure 6. Static water levels measured in monitoring wells MW-1 and DW-2 indicate a vertical groundwater gradient of 0.01 feet per foot downward. Static water levels measured in monitoring wells MW-10 and DW-16 indicate a vertical groundwater gradient of 0.002 feet per foot downward. Static water levels measured in monitoring wells MW-6R and DW-19 indicate a vertical groundwater gradient of 0.07 feet per foot downward. 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 1.2 feet per day. The average groundwater velocity is estimated to be 0.12 feet per day (44 feet per year), based on the average groundwater gradient from the April 15, 2011 water level measurements and an estimated effective porosity of thirty percent. 5.0 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 April 15, 2011 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 acids concentrations were detected in monitoring wells MW-9, MW-10, MW-11, MW-13 and DW-19. Volatile organic acids or metabolic acids indicate the presence and metabolism of HRC. Analytical results for volatile organic acids are summarized in Table 3. Groundwater sample analytical results indicate that several VOCs were detected in the monitoring wells sampled including tetrachloroethene (PCE), tricholoroethene (TEC), cis and trans 1,2 dichloroethene (DCE), and vinyl chloride. PCE was detected at levels exceeding the NCGWS in monitoring wells MW-1, DW-2, MW-5, MW-6R, MW-7, MW-8, MW-10, MW-13, DW-16 and DW-19. PCE concentrations in monitoring wells MW-6R, MW-10 and MW-16 decreased since the previous sampling event, while the concentrations in monitoring wells MW-9, MW-11, MW-13, and DW-19 remained 97626 1 GS011 R079 Page 6 of 9 May 24, 2011 Copyright 2011 Kleinfelder consistent with previous levels. PCE concentrations in monitoring wells MW-1, DW-2, MW-5, MW-7, and MW-8 increased slightly since the previous sampling event. Graphs of the PCE concentrations versus time are included in Appendix A. Based on a review of the graphs, the PCE concentrations have decreasing trends in monitoring wells MW-1, DW-2, MW-6R, MW-9, MW-10, MW-11, MW-13, and DW-19. PEC concentrations have increasing trends in MW-5, MW-7, MW-8, and DW-16. A graph of the average PCE concentrations from all wells versus time is also included in Appendix A. This graph shows the overall average of the twelve wells sampled, an average of the shallow wells, and an average of the deep wells. Note that prior to January 2006, ten or fewer wells were sampled so the averages are based on fewer data points. The trend in the deep wells showed an increase in PCE concentration starting in 2008, which stabilized between January 2009 and October 2010. The average increased in January 2011 due to an increase in PCE concentration in DW-19, and then decreased in April 2011. The average PCE concentration in the shallow wells shows a decreasing trend. A PCE isoconcentration map is shown on Figure 7. TCE was detected at levels exceeding the NCGWS in monitoring wells MW-1, MW-6R, MW-9 and DW-16. Cis-1,2-DCE was detected at levels exceeding the NCGWS in monitoring wells MW-1 and DW-16. Vinyl chloride was detected at levels exceeding the NCGWS in monitoring wells MW-1, MW-9, MW-10, MW-11, MW-13, and DW-16. A summary of historical VOC analytical results is provided in Table 4. A copy of the analytical results including the chain -of -custody form is included in Appendix B. 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. The average PCE concentration versus time graph in Appendix A indicates the average PCE concentration has decreased eight -nine percent (89%) from its peak (approximately 750 pg/L) to the current average PCE concentration (approximately 77 pg/L). PCE concentrations have decreasing trends in wells located in the source area and center of the plume. The presence of daughter products of dechlorination of PCE in monitoring wells MW-1, DW-2, MW-6R, MW-7, MW-8, MW-9, MW-10, MW-11, MW-13, DW-16, and DW-19 also indicates degradation is occurring. 97626 1 GS011 R079 Page 7 of 9 May 24, 2011 Copyright 2011 Kleinfelder Based upon 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 July 2011. 7.0 LIMITATIONS Kleinfelder offers various levels of investigative and engineering services to suit the varying needs of different clients. 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.
