The site is located south of Westpoint Boulevard and east of Viceroy Drive (Figure 1). Rotork, formerly Fairchild Industrial Products Company, occupies the building. An Administrative Agreement with the Registered Environmental Consultant Program was executed March 3, 2009. Impacts from the release of tetrachloroethene from the process room at the site were limited to soil and groundwater. Tetrachloroethene (PCE), trichloroethene (TCE), cis-1, 2-dichloroethene (DCE), and vinyl chloride are the primary contaminants of concern. Confirmation soil samples were collected following approximately one year of operating the SVE system while monitoring emissions. When SVE system emissions laboratory results indicated volatile organic compound (VOC) levels were less than two percent of the baseline readings, samples were collected to assess contaminant levels in the soil. The various vapor extraction wells were also cycled on and off prior to confirmation soil sampling. Contaminant levels detected in the confirmation soil samples were below the target clean-up levels. Target clean-up levels for soil are for unrestricted land use. The target clean-up levels were the lower of either the Preliminary Residential Health -Based Soil Remediation Goal or Protection of Groundwater Preliminary Soil Remediation Goals dated January 2014. A Soil Remedial Action Completion Report was submitted March 26, 2014. The goal of current remedial action at the site is to provide remediation of PCE and daughter products from reductive dechlorination while assuring that known and foreseeable pathways are monitored to protect public health and the environment. Target clean-up levels for groundwater are the Title 15A NCAC 2L Groundwater Standards for Class GA Groundwater (NCGWS). Remedial action will be complete for groundwater when four consecutive quarters of sample results are below the 2L Standards for all the monitoring wells. A summary of groundwater remedial actions to date is included in Section 3 of this report. 11.990015.00 Page 1 of 11 October 3, 2016 © 2016 EnviroTrac AOL env T Environmental Services 2 RECEPTOR SURVEY 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, 2013, a receptor survey was completed within 0.5 miles of the release. The areas within 0.5 miles north and east of the site generally included 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 included residential and industrial properties. This site 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 website, 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 2 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 2). Water wells identified during the receptor survey are not anticipated to be impacted by the release at the site because groundwater flow is to the southeast and the water wells are located more than 1,500 feet southwest of the site, with the exception of two water wells located west of the site. On February 10, 2014, a vehicle reconnaissance was performed within 0.5 miles of the release. No changes to the receptors described above were observed. 11.990015.00 Page 2 of 11 October 3, 2016 © 2016 EnviroTrac Envkonmental S[Zviies 3 HRC INJECTION 15A NCAC 13C .0306 (o)(1) A permit from the Underground Injection Control (UIC) Program of the Division of Water Quality was requested to inject hydrogen release compound (HRC) for remediation of groundwater contamination identified during the Comprehensive Site Assessment. 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, the first round of HRC injection was initiated. 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 3. 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. Following the November 2002 sampling event, additional HRC application in the vicinity of MW-7, MW-9, MW-10, and MW-13 was recommended. A modified permit from the UIC Program to inject additional HRC was requested. 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, installation of the additional injection wells and points was initiated. 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 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 11.990015.00 Page 3 of 11 October 3, 2016 © 2016 EnviroTrac kiwi T Environmental Services 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 3. In May 2007, the installation of additional injection wells, IW-13 and IW-14, was completed. 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 3. 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. In order to further accelerate the process of natural attenuation, an application was submitted 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 request included augmenting the injection well system in the vicinity of MW-9 and MW-11, injecting 3DMe, and conducting remedial monitoring. The Regenesis product, 3-D MicroEmulsion (3DMe), incorporates HRC Advanced and is designed to time release highly efficient electron donors. The 3DMe product is designed to have a greater longevity than HRC alone. Application of the 3DMe as an emulsified suspension in water allowed for a greater radius of influence during injection. A permit was issued by the UIC Program on June 30, 2010. Beginning on September 7, 2010, 3DMe was injected 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 tote with a submersible pump continually mixing the 3DMe and water solution throughout the injection process. Once the solution drained into the injection well, 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 at the site. On October 8, 2013 an application was submitted to the UIC Program to inject 3DMe for remediation of groundwater. A permit was issued by the UIC Program November 22, 2013, and is 11.990015.00 Page 4 of 11 October 3, 2016 © 2016 EnviroTrac Ah Gtt 1vi Environmental Services effective until April 30, 2019. On December 20, 2013 3DMe was injected into five of the injection wells (IW-8, IW-12, IW-13, IW-14 and IW-15). For each injection well, 3DMe was mixed with water at a one to ten ratio in a 250 gallon tote. Once the solution drained into the injection well, an additional 220 to 330 gallons of water was placed into each injection well. Between December 20, 2013, and January 22, 2014, a total 100 gallons of 3DMe and 3,150 gallons of water were injected at the site. The injection well locations are shown on Figure 3. An Injection Event Record was submitted to the UIC Program January 24, 2014. The UIC Program was notified prior to installation of a passive hydrogen diffusion device in monitoring well DW-16 on July 1, 2015. The device is intended to enhance the current remediation regime by targeting the localized area of elevated PCE concentration in the vicinity of monitoring well DW-16. The passive hydrogen diffusion device will increase the degradation rate of chlorinated hydrocarbons but still allow DW-16 to be used as a monitoring point. Hydrogen is supplied from a cylinder that is secured inside a flammable cabinet with two balusters on either side of the cabinet. The hydrogen cylinder regulator is set to 20 pounds per square inch. Standard grade hydrogen (99 percent or greater) is supplied to the diffuser through one quarter inch diameter Parflex 55LT tubing. The Parflex tubing is connected to approximately 40 feet of silicone tubing secured to a PVC frame. The permeability of the silicone tubing allows hydrogen to be released at a size that readily dissolves into the groundwater. Once the hydrogen diffusion device was installed, monthly site visits occurred to record the hydrogen consumption in the injection well and to estimate remaining service life of the hydrogen cylinder. In addition to recording the hydrogen consumption, the pH, temperature, conductivity, oxidation-reduction potential, and dissolved oxygen was monitored periodically. 11.990015.00 Page 5 of 11 October 3, 2016 © 2016 EnviroTrac AOL Environmental Services 4 FIELD SAMPLING ACTIVITIES 15A NCAC 13C .0306 (o)(3) and .0306 (q) Static water levels were recorded in all of the monitoring wells on September 1, 2016 with the exception of MW-12 that was covered by shelving. Table 1 provides a summary of monitoring well construction details and the groundwater elevations. Historical average shallow groundwater elevation measurements are summarized on Figure 4. 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 13 monitoring wells (MW-1, DW-2, MW-5, MW-6R, MW- 7, MW-8, MW-9, MW-10, MW-11, MW-13, DW-16, DW-19, and BW-22) and analyzed for VOCs by EPA Method 8260. Additionally, monitoring wells DW-2, MW-6R, MW-9, MW-10, MW-11, MW-13, DW-16, and DW-19 were analyzed for metabolic acids. Field parameters including oxidation- reduction potential, conductivity, pH, dissolved oxygen, and temperature of representative groundwater samples were recorded from each monitoring well sampled. Groundwater samples were collected using low flow sampling procedures with a peristatic pump. Dedicated tubing in each of the monitoring wells is used for purging and sampling. The wells were first purged of one to two well volumes of water until field parameters stabilized. Groundwater samples were collected and placed in laboratory prepared containers. The groundwater samples were maintained on ice and under chain -of -custody until delivered to Pace Analytical Services, Inc. in Huntersville, North Carolina. Investigation derived waste generated during the monitoring period included 37.7 gallons of purge water from the 13 monitoring wells sampled, PPE, and paper towels. PPE included disposable nitrile gloves. PPE and paper towels were disposed of in appropriate waste disposal receptacles. Purge water was discharged to asphalt pavement in the vicinity of the respective monitoring well to evaporate. The static water levels measured 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 September 1, 2016 groundwater elevations is shown on Figure 5. Static water levels measured in monitoring wells MW-1 and DW-2 indicated a vertical groundwater 11.990015.00 Page 6 of 11 October 3, 2016 © 2016 EnviroTrac e vffii rac Environmental Services gradient of 0.001 feet per foot downward. Static water levels measured in monitoring wells MW-6R and DW-19 indicate a vertical groundwater gradient of 0.03 feet per foot downward. In -situ aquifer tests performed on shallow monitoring wells at the site indicated that the surficial aquifer has an average hydraulic conductivity of 1.2 feet per day. The average groundwater velocity is estimated to be 0.1 feet per day (38 feet per year), based on the average groundwater gradient from the September 1, 2016 water level measurements and an estimated effective porosity of thirty percent. 11.990015.00 Page 7 of 11 October 3, 2016 0 2016 EnviroTrac An G11vffiorac Environmental Services 5 ANALYTICAL RESULTS 15A NCAC 13C .0306 (o)(4) and .0306 (o)(5) The groundwater field analysis generally indicates that the subsurface environment is within acceptable limits for biodegradation to occur. The field measurements recorded on September 1, 2016, 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. The field measurements generally indicate an anaerobic subsurface environment exists in the vicinity of the injection wells. Volatile organic acids have historically been detected throughout the treated area of the plume. Volatile organic acids or metabolic acids indicate the presence and metabolism of HRC/3DMe. The analytical results indicate volatile organic acids are present in each of the groundwater samples analyzed, which represent the treated area of the contaminant plume. 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 PCE, TCE, trans- and cis-1,2-DCE, acetone, vinyl chloride, toluene, and 2- butanone. PCE was detected at levels exceeding the NCGWS in monitoring wells DW-2, MW-6R, MW-8, DW-16, and DW-19. Graphs of the PCE and daughter product concentrations versus time are included in Appendix A. Based on a review of the graphs, the PCE concentrations have decreasing or steady trends in each of the monitoring wells with the exception of MW-8. A graph of the average PCE concentrations from the monitoring wells versus time is also included in Appendix A. This graph shows the overall average of the 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 pre-2006 averages are based on fewer data points. The trend in the deep wells showed an increase in PCE concentration starting in 2008, followed by a decreasing trend after a peak in January 2012. The average PCE concentration in the shallow wells shows a decreasing trend. A PCE isoconcentration map is shown on Figure 6. The extent of the PCE plume has been decreasing since June 2002.

The average PCE concentration versus time graph in Appendix A indicates the average PCE concentration has decreased 94 percent from its peak of 753 micrograms per liter (Ng/L) in 2002 to the current average PCE concentration of 43.5 pg/L. The presence of daughter products of dechlorination of PCE and metabolic acids in the monitoring wells also indicate degradation is occurring throughout the contaminant plume. EnviroTrac recommends monthly passive hydrogen injection monitoring and semi-annual corrective action monitoring should continue. The next corrective action monitoring event should be scheduled for March 2017. 11.990015.00 Page 10 of 11 October 3, 2016 © 2016 EnviroTrac AOL bm�Lil�!SL Environmental Servlcm 7 LIMITATIONS EnviroTrac 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. During the course of the performance of EnviroTrac's services, hazardous materials may have been discovered. EnviroTrac assumes no responsibility or liability whatsoever for any claim, loss of property value, damage, or injury that results from pre-existing hazardous materials being encountered or present on the project site, or from the discovery of such hazardous materials.
