INTRODUCTION On behalf of the City of Charlotte, Geosyntec Consultants of NC, PC (Geosyntec) has prepared this Semi-Annual Monitoring Report, First Half 2016 for the City of Charlotte’s Former York Road Landfill. This report presents the results of groundwater, surface water, and methane monitoring conducted at the former landfill since the previous Semi-Annual Monitoring Report (Geosyntec, 2015) was submitted in November 2015, through April 2016. 1.1 Site Description and History The Former York Road Landfill (herein referred to as the “Site”) is an approximately 400-acre Site located along West Tyvola Road and South Tryon Street (Highway 49) in Charlotte, Mecklenburg County, North Carolina (Figure 1). The Site was operated as an unlined municipal solid waste landfill from 1968 to 1986, with the last expansion occurring in 1983 (under NCDENR Facility Permit Number 60-03). The landfill waste placement area consisted of a total of approximately 168 acres, which was divided into six cells referred to as Landfill Areas A through F. The precise locations of waste placement boundaries are uncertain and have been estimated by others, as shown in Figure 2. The former landfill was developed with the construction of West Tyvola Road, a golf course, and a recreational park following closure in 1986. Today, the Site is utilized by the Renaissance Park Golf Course and Renaissance Park, which include recreational facilities for golf, baseball, soccer, biking, and disc golf. 1.2 Hydrogeologic Setting The Site is located within the Charlotte Belt of the Piedmont Physiographic Province. The topography of the Piedmont Province is generally characterized by gently rolling hills ranging in elevation from approximately 300 to 1200 feet (ft) above mean sea level (MSL), and the Site elevation ranges from approximately 580 to 680 ft above MSL. Geologically, the province is comprised primarily of crystalline metamorphic rocks (schists and gneiss, and to a lesser extent, phyllite and slate) of Precambrian to Paleozoic age. These units are often highly deformed with multiple fracture and foliation planes, which promote anisotropic groundwater flow. The occurrence and movement of groundwater at the Site is typical of the Piedmont formation, and generally occurs within two hydrogeologic units. A shallow hydrogeologic unit typically occurs within the soils and saprolite (weathered residuum which mantles Semi-Annual Monitoring Report – First Half 2016 Former York Road Landfill, Charlotte, North Carolina May 2016 GC5699A\FINAL 2016 May York SAR.docx 2 05.2016 bedrock). A deeper hydrogeologic unit is generally associated with secondary porosity (fractures or open spaces) within the crystalline bedrock. A transition zone of fractured bedrock occurs between saprolite and bedrock and is generally referred to as partially weathered rock (PWR). Groundwater flow in the shallow hydrogeologic unit is controlled by local topographic features, where recharge occurs in upland areas and discharge occurs in drainage features such as streams, rivers, or lakes. Recharge to the shallow hydrogeologic unit is primarily the result of infiltrating precipitation. Groundwater flow in the deeper water- bearing zone is controlled by the distribution and degree of interconnection of openings in the rock. 1.3 Regulatory Authority The York Road Landfill was closed under the 10 NCAC 10G, Section .0500 rules as referenced in the 21 August 1987 closure letter from the North Carolina Department of Human Resources, Division of Health Services. These regulations were transferred and recodified into title 15A NCAC 13B Section .0500, effective April 1990. Water quality monitoring at the Former York Road Landfill is conducted pursuant to the Water Quality Monitoring Plan (WQMP; Delta, 2004), which was developed in accordance with relevant and applicable North Carolina Department of Environmental Quality (NCDEQ, formerly North Carolina Department of Environment and Natural Resources [NCDENR]) Solid Waste Management Rules. Groundwater and surface water sampling is conducted semi-annually, typically in March and September. Landfill gas monitoring is conducted pursuant to the Landfill Gas Monitoring Plan (LGMP; HDR, 2011) for the Site. As stated in the LGMP, the 15A NCAC 13B Section .0500 rules and closure letter for the Site are silent on the issue of landfill gas monitoring. Therefore, landfill gas monitoring is regularly conducted in general accordance with the LGMP, which was developed to provide reasonable protection to public health and the environment. Landfill gas monitoring is conducted on a quarterly basis (typically in January, April, July, and October). Semi-Annual Monitoring Report – First Half 2016 Former York Road Landfill, Charlotte, North Carolina May 2016 GC5699A\FINAL 2016 May York SAR.docx 3 05.2016 2. MONITORING ACTIVITIES AND FIELD METHODOLOGY The following sections describe field methodology for groundwater, surface water, and methane monitoring conducted during the current reporting period. 2.1 Groundwater Monitoring Groundwater monitoring was conducted pursuant to procedures in the WQMP. The current monitoring network includes twenty-three (23) monitoring wells, with eighteen (18) groundwater monitoring wells included in the sampling network pursuant to the WQMP. Monitoring wells are screened across one or more of the three hydrogeologic units at the Site (saprolite, PWR, and bedrock). Monitoring well construction details are listed in Table 1, and locations are depicted in Figure 2. A schedule for sample collection and associated laboratory analyses conducted for each well under the WQMP is listed in Table 2. Groundwater sampling, water level measurements, and laboratory analysis conducted during this reporting period were performed from 21 through 24 March 2016 by Pace Analytical Services (Pace) of Charlotte, NC. Groundwater level measurements from groundwater wells that are part of the monitoring network were collected during a single day (on 21 March 2016) in order to evaluate the potentiometric surface and groundwater flow direction at the time of measurement. Prior to groundwater sampling, three to five well volumes were purged from each well using a submersible pump or dedicated, disposable bailer. During purging, groundwater parameters (temperature, pH, and specific conductance) were measured with daily-calibrated multimeters to assess stabilization. If a well became dry prior to purging three well volumes, it was allowed to recharge, and a sample was collected. Sample collection was performed using a dedicated, disposable bailer, and samples were placed in laboratory-provided sample containers. Samples were transported to the laboratory on ice, under chain-of- custody. Non-dedicated sampling equipment was decontaminated in accordance with procedures described in the WQMP. Field quality assurance/quality control (QA/QC) samples including a field (rinsate) blank, a trip blank, and a field duplicate (from parent sample DMW-05) were analyzed. Field data sheets for groundwater sampling efforts are included in Appendix A. In coordination with the March 2016 groundwater sampling event, Geosyntec conducted a groundwater sampling technique comparison study to evaluate the use of Semi-Annual Monitoring Report – First Half 2016 Former York Road Landfill, Charlotte, North Carolina May 2016 GC5699A\FINAL 2016 May York SAR.docx 4 05.2016 passive sampling technology at the Site for long term monitoring. The objective of this effort was to demonstrate whether similar concentrations of VOCs and metals could be obtained using dual-membrane passive diffusion bags (PDBs) and traditional well- purge/low flow sampling and to evaluate whether PDBs will provide high quality data that accurately represents groundwater quality at the Site. A technical memorandum included as Appendix B provides an overview of the groundwater sampling techniques used in the comparison study, a discussion of the analytical data regarding the ability of the PDBs to obtain representative samples of VOC and metals concentrations at the Site, and a recommendation to employ PBDs for future sampling efforts at the Site. 2.2 Surface Water Monitoring Surface water monitoring was conducted pursuant to procedures described in the WQMP. The surface water monitoring system consists of six sample locations (listed in Table 2 and depicted on Figure 2) on the three streams that cross the Site: Sugar Creek (SC), and two unnamed tributaries referred to as the north tributary (NT), and the south tributary (ST). Sample locations generally correspond to one upstream location and one downstream location from each stream. Laboratory analyses conducted for each surface water sample location are listed in Table 2. Surface water monitoring during the current reporting period was conducted on 21 through 24 March 2016 by Pace. Samples were collected from locations where flow was occurring (where possible) and from locations away from the stream bank to minimize disturbance to the stream bed. Samples were placed in laboratory-provided sample containers and transported to the laboratory on ice, under chain-of-custody. Field measurements of pH, specific conductance, and temperature were recorded for each sample at the time of collection. Field data sheets for surface sampling efforts are included in Appendix A. 2.3 Water Supply Wells Pursuant to the sampling schedule in WQMP (Table 2), water supply wells were not sampled in March 2016. Sampling of the water supply wells that are part of the monitoring program is scheduled to be conducted in September 2016. Semi-Annual Monitoring Report – First Half 2016 Former York Road Landfill, Charlotte, North Carolina May 2016 GC5699A\FINAL 2016 May York SAR.docx 5 05.2016 2.4 Methane Monitoring Methane monitoring was carried out pursuant to the LGMP. Methane monitoring activities include quarterly measurement of methane concentrations at methane probes, active extraction systems, and other points where methane could accumulate such as light poles and storm drains.Table 3 lists points that are the subject of quarterly or annual methane monitoring. Passive structures and Site features that are part of the methane monitoring program are depicted in Figures 3A and 3B. In addition to methane monitoring, methane alarm systems and active extraction systems are periodically inspected and maintained. Quarterly methane monitoring events during this reporting period were carried out by Geosyntec from 20 through 21 January, and 20 through 21 April 2016. Inspection and maintenance of the three methane detection systems (located in the golf course clubhouse, golf course maintenance building, and baseball field concession building) was conducted by LEI Systems on 8 April 2016. These systems consist of about 40 Macurco GD-2A detectors connected to control panels and audible alarms which notify authorities and occupants in the event of methane detection. Additionally, stand-alone, plug-in Macurco GD-21 methane detectors are located in the Leatherman maintenance building, golf course chemical storage building, and baseball field ticket booth. Two plug-in First Alert Model GCO1CN methane alarms are located inside the John Crosland School. Operation of the two active extraction systems (clubhouse and northeast boundary) was observed by Geosyntec during quarterly monitoring events. Effluent methane concentrations, blower vacuum, air flow rates, and blower operating hours were recorded, where possible. As part of efforts to address possible methane migration at the northeast boundary, a pilot test to evaluate the potential effectiveness of a supplemental, in-soil, perimeter gas extraction system (PGES) was conducted at the Site on 19 January 2016. The pilot study was carried out with the purpose of evaluating the use of active extraction well points in the soil screened below the depth of the existing extraction system’s trench to prevent off-Site migration of landfill gas. A report has been prepared to summarize the methods and results of the pilot test, and is included as an attachment to this report as Appendix C. Semi-Annual Monitoring Report – First Half 2016 Former York Road Landfill, Charlotte, North Carolina May 2016 GC5699A\FINAL 2016 May York SAR.docx 6 05.2016 Visual inspection of the landfill cap was conducted pursuant to the LGMP during quarterly monitoring events in January and April 2016. The purpose of the visual inspections is to identify areas of concern such as significant settlement, formation of subsurface voids, locations of methane venting, odors, distressed vegetation, or exposed waste.

MONITORING RESULTS The following sections describe the results of groundwater, surface water, and methane monitoring conducted during the current reporting period. 3.1 Groundwater 3.1.1 Potentiometric Surface Elevation and Groundwater Flow Direction Static groundwater elevations measured on 21 March 2016 are listed in Table 1, and historical groundwater elevations are listed in Table 4.Figure 4 displays a potentiometric surface map and inferred groundwater flow direction for the Site. Groundwater within the saprolite and shallow bedrock aquifer generally flows toward the southwest, following the surface topography toward Sugar Creek. The potentiometric gradient is approximately 0.013 ft/ft across the Site. The flow direction observed on 21 March 2016 was generally consistent with historical observations at the Site. Groundwater elevations were generally higher in March 2016 as compared to historical averages since 2006, and the March 2016 reading was the highest reading since 2006 in 3 of 21 wells measured; however, each recorded elevation was within four feet of its historical average. 3.1.2 Groundwater Analytical Results A summary of detected constituents and field parameters (pH, specific conductance, and temperature) from monitoring well and water supply well samples collected during the March 2016 groundwater sampling event is included in Table 5 and laboratory analytical reports are included in Appendix D. Low levels of some volatile organic compounds (VOCs) and metals were detected in samples collected from Site monitoring wells in March 2016. Select compounds were detected in several wells at concentrations above the Title 15A North Carolina Administrative Code (NCAC), Subchapter 2L Standards (2L Standards). One or more VOCs exceeded their 2L Standard in 4 of the 18 monitoring wells sampled, and one or more metals were detected above their 2L Standard in 9 of the 18 wells sampled. Figure 5 displays a map with exceedances of the 2L Standard shown for each well. The March 2016 analytical results reveal the following: Semi-Annual Monitoring Report – First Half 2016 Former York Road Landfill, Charlotte, North Carolina May 2016 GC5699A\FINAL 2016 May York SAR.docx 8 05.2016 x 1,2-Dichloropropane was detected above its 2L Standard of 0.6 micrograms per liter (μg/L) in two wells, DMW-01 at 2.7 μg/L and DMW-06 at 2.2 μg/L. x 1,4-Dichlorobenzene was detected above its 2L Standard of 6 μg/L in one well, DMW-01 at 15.1 μg/L. x Trichloroethene (TCE) was detected above its 2L Standard of 3 μg/L in two wells, DMW-01 at 3.8 μg/L and DMW-06 at 5.5 μg/L. x Tetrachloroethene (PCE) was detected above its 2L Standard of 0.7 μg/L in three wells, DDW-01 at 1.4 μg/L, DMW-02B at 1.1 μg/L, and DMW-06 at 1.7 μg/L. x Vinyl chloride (VC) was detected above its 2L Standard of 0.03 μg/L in two wells, DMW-01 at 2.8 μg/L and DMW-06 at 3.7 μg/L. x Barium was detected above its 2L Standard of 700 μg/L in one well, DMW-02A at 1,460 μg/L. x Chromium was detected above its 2L Standard of 10 μg/L in one well, DMW-A at 11.6 μg/L. x Iron was detected above its 2L Standard of 300 μg/L in seven wells, with the highest concentration in YRW-10C at 119,000 μg/L. x Manganese was detected above its 2L Standard of 50 μg/L in eight wells, with the highest concentration in DMW-01 at 22,600 μg/L. Historic groundwater analytical data are included in Appendix E. Groundwater VOC and metals concentrations detected during the March 2016 sampling event were generally consistent with historic trends for these wells. Data from the March 2016 event included 27 instances of constituents exceeding their 2L Standard which is slightly lower than the number of exceedances in September 2015 (29 exceedances), and continues a generally downward trend in the total number of exceedances over the past six years. The decrease in 2L Standard exceedances is evidence of an ongoing declining trend in groundwater concentrations at the Site. The presence of chlorinated daughter products of PCE (TCE, cis-1,2-DCE, and VC) in wells may indicate that at Semi-Annual Monitoring Report – First Half 2016 Former York Road Landfill, Charlotte, North Carolina May 2016 GC5699A\FINAL 2016 May York SAR.docx 9 05.2016 least some reductive dechlorination has occurred in Site groundwater, which can occur naturally under favorable (generally anaerobic) conditions. These biodegradation processes, in combination with other natural processes including sorption, dilution, and chemical degradation, contribute to natural attenuation of groundwater contaminants and reductions in concentrations over time. Field parameter results were generally consistent with historical trends. pH values fell between 6.0 and 8.1, with the exception of DMW-02A, with a pH of 12.5. The pH at DMW-02A has typically been higher than other wells, which is potentially attributable to cement grout used in well construction. Specific conductance ranged from 70.5 to 1,472 microsiemens per centimeter (μS/cm), with the exception of MW-02A (7,830 μS/cm) which has also exhibited high specific conductance historically. 3.1.3 Groundwater Sampling Methodology Comparison Study The procedures and results of a groundwater sampling methodology comparison study are presented in a technical memorandum included as Appendix B. The results of this study support a recommendation that future groundwater monitoring at the site be conducted using dual-membrane PDBs, allowing for decreased sampling effort and investigation-derived waste generation while meeting data quality objectives. 3.2 Surface Water A summary of detected constituents and field parameters (pH, specific conductance, and temperature) from samples collected during the March 2016 surface water sampling event is included in Table 6, and laboratory analytical reports are included in Appendix D. Trace levels of barium were detected in all six surface water samples, at concentrations below its Title 15A NCAC Subchapter 2B Water Supply Standard (2B Standard) of 1,000 μg/L. No VOCs were detected in surface water samples during the March 2016 sampling event. Field parameter results were generally consistent with historical trends. pH ranged from 6.9 to 8.5 and specific conductance ranged from 220.1 to 431.0 μS/cm. Semi-Annual Monitoring Report – First Half 2016 Former York Road Landfill, Charlotte, North Carolina May 2016 GC5699A\FINAL 2016 May York SAR.docx 10 05.2016 3.3 Methane Results of methane monitoring activities from January 2015 through April 2016 at select locations are summarized in Table 7, and complete landfill gas monitoring results from November 2015 through April 2016 are included in Appendix F.Table 7 and Appendix F include non-routine system performance assessment monitoring in the northeast boundary area which is not part of regular, quarterly monitoring. Historical landfill gas data from January 2012 through April 2016 is included in Appendix G. The following sections discuss these results. 3.3.1 Passive Methane Monitoring Points Passive methane probe monitoring results from the most recent monitoring event (April 2016) are displayed in Figure 6 (northeast boundary) and Figure 7 (South Tryon Street). Methane concentrations at select subsurface monitoring probes exceeded the lower explosive limit (LEL) of 5% along the South Tryon Street boundary and northeast boundary during the January and April 2016 monitoring events. No LEL exceedances were observed in off-Site probes during this reporting period. Although off-Site methane concentrations above the LEL were not detected along the northeast boundary, periodically elevated concentrations of methane at select probes indicate it is possible that off-Site migration of methane above the LEL may occur in the subsurface along the northeast boundary. Passive monitoring points in the vicinity of the John Crosland School (formerly the 5146 Ten Parkway Plaza Boulevard Building), located next to the northeast boundary, were monitored on a monthly basis during the current reporting period in response to past, occasional subsurface methane readings above the LEL in this area. Methane concentrations were not detected in the subsurface above the LEL in these probes during this reporting period. Methane monitoring alarms are located within the school, as discussed in Section 3.3.2. Efforts to mitigate possible off-Site methane migration in the northeast boundary undertaken during this reporting period included a pilot test evaluation of the potential effectiveness of a supplemental, in-soil, perimeter gas extraction system. A report summarizing the implementation and results of this pilot test is included as Appendix C. Methane was not detected above 25% of the LEL in the vicinity of light poles or scoreboards that are part of the monitoring program, nor inside other structures including buildings and storm drains monitored during this period. Semi-Annual Monitoring Report – First Half 2016 Former York Road Landfill, Charlotte, North Carolina May 2016 GC5699A\FINAL 2016 May York SAR.docx 11 05.2016 3.3.2 Active Extraction Systems 3.3.2.1 Golf Clubhouse System The golf clubhouse venting system utilizes a five-horsepower Rotron regenerative blower to extract methane from the clubhouse sub-slab gravel base using a combination of 31 horizontal, open-ended, PVC pipes grouped together into seven manifolds and eight vertical extraction points installed just below the building floor slab. In addition, nine vertical passive air infiltration vents are situated at regular intervals along the northern and southern sides of the clubhouse. These perforated pipes allow atmospheric air to be pulled into the subsurface to minimize pulling additional methane into the building from nearby landfill areas. The ability to pull in ambient air lessens the magnitude of the vacuum being applied to the surrounding soils and adds clean dilution air. The clubhouse venting system layout is shown in Figure 8. The clubhouse active extraction system was observed to be operating during both the January and April 2016 landfill gas monitoring events, and was not reported to have stopped operating during this reporting period. Methane measurements from several points along the system that were recorded during landfill gas monitoring are included in Appendix F. 3.3.2.2 Northeast Boundary System The northeast boundary venting system utilizes a ten-horsepower Rotron regenerative blower, which removes methane vapors from an approximately 17-foot deep, 1,400-foot long interceptor trench originally installed in 1990. The trench was backfilled with gravel, and a bentonite/compacted soil cap was added to the top of the trench to help limit atmospheric air infiltration. A four-inch diameter corrugated, perforated pipe was installed in gravel, 3 to 4 ft above the base of the trench. Initially, four solid-walled, vertical PVC monitoring points (SU-0 to SU-3) were installed into or near the trench. An additional 4-inch diameter solid walled PVC bypass line was installed in July 1995 to address potential off-site methane migration in the northern portion of the trench. SU-4 was installed at this time as an access point to clean this line. The system was fitted with separate below grade valves that allow methane removal to be focused on the northern section of the trench. Semi-Annual Monitoring Report – First Half 2016 Former York Road Landfill, Charlotte, North Carolina May 2016 GC5699A\FINAL 2016 May York SAR.docx 12 05.2016 In the fall of 2008, the City modified the system by installing six vertical extraction wells (SU-5 through SU-10) and two other converted vertical wells (SU-1 and SU-2). Valves were placed on each well to control and improve landfill gas extraction along the northeast landfill boundary. A condensate (moisture) drain was installed on 29 January 2009, to drain the excess water that accumulated due to the 2008 revision to the extraction system. The northeast boundary active extraction system was observed to be operating during both the January and April 2016 landfill gas monitoring events. An hour meter which records operating time for the system’s blower indicated that there was less than one hour of downtime between the October 2015 and April 2016 monitoring events. Figure 9 displays the valve status, applied vacuum, air flow, and methane concentration at system vacuum extraction points as observed in April 2016. This figure shows that the system is configured such that vacuum is focused on the middle section of the trench, which also corresponds to the highest methane concentrations measured within the trench. Air flow measurements were also taken at each active extraction well. The sum of the measurements indicates the total system air flow rate was approximately 428 standard cubic feet per minute (scfm) during the April 2016 monitoring event. 3.3.2 Methane Detection Systems Methane detectors were confirmed to be active (by observation of a green status indicator light) by Geosyntec during quarterly landfill gas monitoring events. The results of inspection and maintenance of the three methane detection systems (golf course clubhouse, golf course maintenance building, and baseball field concession building) conducted by LEI Systems on 8 April 2016 showed that these systems were functioning properly. No methane detections by these systems were reported during this reporting period. One alarm was reported at the golf maintenance building which was reported to have been caused by maintenance activities within the building. No alarms were reported from the plug-in methane detectors located within the softball ticket booth, Leatherman maintenance building, golf course chemical storage building, and the John Crosland School. 3.3.3 Landfill Cap Inspection and Repairs Visual inspection of the landfill cap was completed by Geosyntec during quarterly monitoring in January and April 2016. During the April 2016 landfill cap inspections, Semi-Annual Monitoring Report – First Half 2016 Former York Road Landfill, Charlotte, North Carolina May 2016 GC5699A\FINAL 2016 May York SAR.docx 13 05.2016 settlement was observed along the eastern side of light pole SLP-07. Methane was not detected around the area of settlement. This location was excavated to expose subsurface voids and was filled with approximately 12 cubic yards of controlled low strength material (flowable fill) by Harvest Environmental Services, Inc. on 3 May 2016.

SUMMARY, CONCLUSIONS AND RECOMMENDATIONS The following sections summarize findings and conclusions based on data collected during the first half of 2016 and historical data collected at the Site. 4.1 Groundwater x Groundwater elevations were generally higher than elevations observed in recent years during the March 2016 groundwater monitoring event, and the highest recorded groundwater elevations since 2006 were measured in 3 of 21 wells. x Groundwater flow at the site was generally consistent with historical observations, with a primary flow direction to the southwest toward Sugar Creek. x Relatively low levels of VOCs were present in Site groundwater during monitoring conducted in March 2016. One or more VOCs exceeded their 2L Standard in 4 of the 18 wells sampled. VOCs exceeding the 2L Standard in at least one Site well were 1,2-dichloropropane, 1,4-dichlorobenzene, TCE, PCE, and VC. x Low levels of metals were present in Site groundwater during monitoring conducted in March 2016. One or more metals were detected above their 2L Standard in 9 of the 18 wells sampled. Metals exceeding the 2L Standard in at least one Site well were barium, chromium, iron, and manganese. x Data from the March 2016 groundwater monitoring event included 27 instances of constituents exceeding their 2L Standard, which is the lowest number of exceedances of the 2L Standard from any sampling event over the past six years. The decrease in 2L Standard exceedances is evidence of an ongoing declining trend in groundwater concentrations at the Site. x Analytical results from the groundwater sampling methodology comparison study conducted in coordination with the March 2016 groundwater sampling event indicated that PDBs were able to obtain representative samples of VOC and metals from a select subset of groundwater wells at the Site.

No VOCs were detected in surface water samples collected in March 2016. 4.3 Methane x Methane was not detected above 25% of the LEL in the vicinity of monitored light poles or scoreboards nor inside other monitored structures during the reporting period. x Methane concentrations at select subsurface monitoring probes exceeded the LEL along the South Tryon Street boundary and northeast boundary. x Methane concentrations in off-Site subsurface monitoring probes near the South Tryon Street boundary and northeast boundary remained below the LEL during this reporting period, although concentrations at the Site boundaries indicate that subsurface off-Site methane migration at concentrations above the LEL may occur. x Efforts to mitigate possible off-Site methane migration in the northeast boundary undertaken during this reporting period included performing a pilot test evaluation of the potential effectiveness of a supplemental, in-soil, PGES. Results of this evaluation indicated that a wellpoint vapor extraction system located between the existing extraction trench and the landfill could be effective in removing methane in the interval below the bottom of the trench and above the water table to achieve methane capture and removal. 4.4 Recommendations Efforts to address possible methane migration at the northeast boundary are ongoing. Geosyntec recommends, and the City has expressed an intention to install, a supplemental PGES between the existing extraction trench and landfill based on the results of the pilot test. The PGES is currently being designed. At the City’s request, Geosyntec is preparing an updated monitoring plan for the Site which will combine the groundwater sampling plan and landfill gas monitoring plan into a single document. PDB groundwater sampling techniques will be incorporated Semi-Annual Monitoring Report – First Half 2016 Former York Road Landfill, Charlotte, North Carolina May 2016 GC5699A\FINAL 2016 May York SAR.docx 16 05.2016 into the updated landfill gas and groundwater monitoring plan. Dual-membrane PDB sampling is recommended for future groundwater sampling at the Site, beginning with the September 2016 sampling event.

Ahrens, P.E. - Geosyntec Doug Pierotti – City of Charlotte Subject: Technical Memorandum - Groundwater Sampling Methodology Comparison Study Former York Road Landfill, Charlotte, North Carolina 1. INTRODUCTION On behalf of the City of Charlotte, Geosyntec Consultants of NC, PC (Geosyntec) has prepared this Technical Memorandum summarizing a Groundwater Sampling Methodology Comparison Study for the Former York Road Landfill (Site), located at along West Tyvola Parkway and South Tryon Street (Highway 49) in Charlotte, Mecklenburg County, North Carolina. The purpose of this report is to evaluate an alternative groundwater sampling technique using passive-diffusion bag (PDB) samplers. The objective of this effort is to demonstrate whether representative sample data for volatile organic compounds (VOCs) and metals (RCRA metals, iron, manganese, and mercury) can be obtained using dual-membrane PDB samplers in order to evaluate whether an alternative groundwater sampling technique to well-purge volume sampling can be used to provide high quality data which accurately represents groundwater quality at the Site. PDB sampling has demonstrated advantages to well-purge volume sampling which include reduced field efforts required in data collection, reduced volume of investigation derived wastes (IDW) generated, and as result, lower relative costs for sampling efforts. This study was performed pursuant to a 19 February 2016 letter (Subject: Notification of Groundwater Sampling Comparison Study) from Geosyntec on behalf of the City of Charlotte to Jaclynne Drummond of the NC Department of Environmental Quality (DEQ) which stated the intent and general approach to conduct this study. This technical memorandum provides an overview of the evaluated sampling techniques, a summary of the activities performed, a presentation of the Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 2 GC5699A\FINAL Appendix B - GW Sampling Comparison Study.docx laboratory data and a comparison of results, and recommendations for sampling techniques to be employed during future efforts at the Site. 2. OVERVIEW OF GROUNDWATER SAMPLING TECHNIQUES The following sections present an overview of groundwater sampling techniques used in this study. 2.1 Current Well-Purge/Low-Flow Sampling Current groundwater sampling at the site employs a hybrid of well-purge and low-flow sampling techniques. The sampling methodology is described in the Site Water Quality Monitoring Plan (WQMP; Delta, 2004). Prior to sample collection, each well is purged of three to five times the volume of standing water in the well casing. Wells purged dry are allowed to recover sufficiently to allow for sampling collection. If recovery takes longer than eight hours to occur, the well may be sampled within a 24-hour period of purging. Purged water is discharged to the ground surface at each well. In addition to purging volume requirements, field parameters are monitored during purging to assess stabilization. Temperature, pH, and specific conductivity of purged water are measured, and stabilization is achieved when temperature and specific conductivity are within ±10% on successive measurements and pH variance is within ±0.02 pH over three consecutive measurements. The combination of well-purge volume requirements and stabilization criteria of field parameters represents a hybrid of low-flow and well-purge sampling techniques. Well-purge sampling is sometimes referred to as “conventional” sampling because it has been the approach most widely employed in past decades. In theory, this technique removes stagnant well water and brings fresh water into the well from the adjacent aquifer formation(s), thus providing a flow-weighted sample of the aquifer adjacent to the entire well screen interval or open borehole. The relatively high degree of pumping stress associated with well-purge sampling mixes contaminant concentrations from various contributing zones and can induce movement of contaminants into the well from zones not adjacent to the well screen (ITRC, 2004). Depending on the amount of water in the well, this method can generate a large volume of purge water requiring management and disposal. Low-flow sampling methods were developed to minimize disturbance of the groundwater system and reduce turbidity in samples. For the low-flow method, completion of purging is based on stabilization of field parameters. Stabilization parameters monitored during purging often include temperature, pH, conductivity, dissolved oxygen, ORP, and turbidity. The pumping rate is set such that the drawdown within the well reaches steady-state. Once some or all of the field parameters have stabilized within preset criteria, sampling may commence from Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 3 GC5699A\FINAL Appendix B - GW Sampling Comparison Study.docx the pump discharge stream. The sampling methodology currently employed at the Site uses parameter stabilization elements of low-flow sampling, but does not necessarily require stabilization of drawdown during sampling. Under the current groundwater sampling schedule, groundwater samples are collected semiannually (in March and September) from eighteen groundwater monitoring wells per event, at the Site. Typically, the time invested (which also includes surface water sampling) is around 50 worker-hours per sampling event. 2.2 Passive Diffusion Bag Sampling The proposed PDB sampling methodology uses Dual Membrane PDB samplers produced by EON Products, Inc. which are capable of collecting samples for analysis of both metals and VOCs. The Dual Membrane PDBs use two semipermeable membranes and rely on the diffusion process where select compounds will migrate across the membrane barriers. Traditional PDBs have been widely used since 1998 and feature a single membrane capable of allowing VOCs to diffuse across it, but not larger molecules (such as metals). Traditional PDB samplers consist of laboratory-grade water enclosed in a low-density polyethylene (LDPE) sleeve, and are deployed to a target depth interval within a screened zone or open borehole of a well. The samplers are then allowed to reach equilibrium with the groundwater, at which time they are retrieved and the sample is transferred to a standard laboratory container for submittal and analysis. The Dual Membrane PDBs include a second, more porous upper membrane which allows larger molecules including metals to diffuse across it. Therefore, the Dual Membrane PDBs can be used to collect samples for analysis of both VOCs and metals. Dual Membrane PDBs were recently developed and as a result there is a limited record of their use compared to single membrane PDBs. A summary of comparative results of Dual Membrane PDBs to other sampling methods provided by EON Products is included as Attachment A to this memorandum. Advantages associated with PDB sampling methods include reduced sampling effort due to ease of deployment and sampling, minimized waste generation and handling requirements, and cost savings. Traditional PDBs have been shown to produce representative groundwater samples under a variety of hydrogeologic conditions. 3. SCOPE AND METHODS The comparison study consisted of sampling a subset of Site wells using both dual-membrane PDB sampling and the well-purge/low-flow sampling method currently employed at the Site for analysis of VOCs and metals which are typically analyzed at selected wells. Six wells representing a range of detected constituents and well construction types were sampled using Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 4 GC5699A\FINAL Appendix B - GW Sampling Comparison Study.docx Dual Membrane PDBs. During the previous sampling event in September 2015, these six wells collectively had detections of every analyte detected at concentrations above the Title 15A North Carolina Administrative Code (NCAC), Subchapter 2L Standards (2L Standards) in Site groundwater since 2008.Figure 1 presents the well sampling locations at the Site, and a summary of well construction details and the constituents of interest for each well are presented in Table 1. Passive sampling of the six comparison study wells was employed during the March 2016 semiannual sampling event in two mobilizations. During the first mobilization to the Site on 3 March 2016, Geosyntec field staff deployed one PDB in each of the six selected wells at the midpoint of the screened interval, or the midpoint of the water column if the screen was not fully submerged. The PDBs were allowed to equilibrate for 21 days, which is consistent with the three-week equilibration period recommended by EON Products. During the second mobilization on 24 March 2016 (conducted concurrently with the semiannual sampling event), Pace Analytical Service (Pace) field staff removed the PDBs from the wells and the water from the PDBs was collected in laboratory-provided sample containers. Immediately after each PDB was recovered, its associated well was sampled by the well-purge/low-flow technique historically used at the Site. Both sets of samples from each well were transported to the Pace laboratory (Charlotte, NC) on ice, under chain-of-custody, and analyzed for parameters typically analyzed at each well as described in the WQMP. Field data sheets for groundwater sampling efforts are included as an attachment to the Semi-Annual Monitoring Report — First Half 2016 (SAMR; Geosyntec, 2016). 4. ANALYTICAL RESULTS AND COMPARISON ANALYSIS The following sections present the basis for comparison of analytical data between the two sampling methods analyzed and the results of the comparison study. 4.1 Comparison Overview The Interstate Technology Regulatory Council (ITRC) guidance document Technical and Regulatory Guidance for Using Polyethylene Diffusion Bag Samplers to Monitor Volatile Organic Compounds in Groundwater (ITRC, 2004) provides guidance on comparing PDB sampling results with other sampling methods. The document explains that differences between analytical results are expected due to inherent differences between sampling methodologies, and that similar results between sampling methods should not be a requirement for PDB data to be acceptable. Instead, the analytical results should be evaluated as “consistent, coherent, and interpretable in context with all available information.” The ITRC guidance document indicates Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 5 GC5699A\FINAL Appendix B - GW Sampling Comparison Study.docx that statistical approaches can be utilized to perform side-by-side comparisons between data collected sequentially by altering methods; however, comparison of PDB data to historical data collected through purge sampling methods may also be acceptable. Examples of comparison criteria include relative percent difference (RPD) between data pairs, data comparison to the laboratory reporting limit (e.g. sample results close to the report limit may be evaluated differently than results with higher concentrations), and relative magnitude of sample results (e.g., if one PDB sample result is greater than or equal to the conventional sample result, PDB sampling is considered acceptable for the well). Methods used herein to compare data sets included calculations of the RPD to evaluate the correlation of the PDB data to the well-purge/low-flow sampling data. Additionally, a comparison of non-detect results obtained from both methods was conducted to identify potential false positive or negative results. The RPD between data points was calculated as the quotient of the difference between the results and the average of the results using the formula below. ܴܲܦ = ቆܥଵ െܥଶ ஼భା஼మଶ ቇ × 100% Where: C1 = the concentration by one sampling method C2 = the concentration of the compared sampling method The calculated RPD values were compared against the EPA Region IV validation limit of 30% for aqueous duplicate samples. Sample results were considered to compare well if the RPD between concentrations was less than 30%, or if both sample results were below 5 micrograms per liter (ȝg/L) because of the high degree of variability in the RPD for small differences in concentrations at this level. A summary of the March 2016 comparison study groundwater analytical detections is presented in Table 2 and the associated laboratory analytical report is included as an attachment to the Semi-Annual Monitoring Report (Geosyntec, 2016). Low levels of some VOCs and metals were detected in samples collected from the six comparison study wells in March 2016. Several compounds were detected in multiple wells at concentrations above the 2L Standards. One or more VOCs exceeded their 2L Standard in three of the six monitoring wells sampled, and one or more metals were detected above their 2L Standard in five of the six wells sampled. For reference, Table 3 presents a summary of historical constituent of interest concentrations at each Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 6 GC5699A\FINAL Appendix B - GW Sampling Comparison Study.docx of the six comparison study wells via well-purge/low-flow sampling techniques, from March 2008 through March 2016. 4.2 Comparison of Well-Purge/Low-Flow and PDB Sample Results The well-purge/low-flow and PDB groundwater sample results were initially compared on a point-by-point basis for 346 sample pair data points (6 paired sample locations, analyzed using EPA Method 6010 & 7470 [metals] and EPA Method 8260 [VOCs]). The 346 sample pairs generally compared well: 87% of the data pairs (300) were non-detect in both the well- purge/low-flow sample and its corresponding PDB sample, while 10% of the data pairs (36) were detected in both sample types, and 3% of data pairs (10) were detected in one sample type but not the other. To focus the comparison study analysis on constituents of interest for this Site, this dataset was reduced to 47 sample pair data points which include constituents that were detected at a concentration above their 2L Standard at least once since 2008 in at least one of the six wells. These constituents are included in Table 1. The 47 paired comparisons are subdivided in Table 4 into the four categories listed below on the basis of constituent detection: x “Both Non-Detect” – The compound was not detected in the well-purge/low-flow sample nor the PDB sample. One of the data pairs was Both Non-Detect. Note that 299 other data pairs were also Both Non-Detect, which were not included in the focused subset of 47 pairs under investigation, as these were of compounds that were not recently detected above the 2L Standard at the Site. x “False Positives” – The compound was not detected in the well-purge/low-flow sample but was detected in the PDB sample. Three of the paired comparisons were False Positives. The False Positive results are discussed in further detail in Section 4.2.1. x “False Negatives” – The compound was detected in the well-purge/low-flow sample but was not detected in the PDB sample. Seven of the paired comparisons were False Negatives. The False Negative results are discussed in further detail in Section 4.2.2. x “Both Detect” – The compound was detected in both the well-purge/low-flow sample and the PDB sample. A total of 36 paired comparisons were Both Detect. A statistical evaluation of these sample results is provided in Section 4.2.3. The concentrations of metals in groundwater sampling results can be influenced by the presence of turbidity in the sampled groundwater. Generally, higher turbidity levels in groundwater Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 7 GC5699A\FINAL Appendix B - GW Sampling Comparison Study.docx samples corresponds with higher metals concentrations as sorbed metals in turbid water contributes to higher concentrations in the aqueous sample. Turbidity effects may have influenced well-purge/low-flow metal results during this study. Although turbidity was not directly measured during sampling, sample appearance was noted for each well-purge/low-flow sample, which can be used as a proxy for turbidity. Well-purge/low-flow samples from five of the six wells were described as “clear”, while the sixth well, DMW-A, was noted as “murky”, indicating a higher turbidity level. DMW-A was also the well with the least agreement between PDB results and well-purge/low-flow results, and well-purge/low-flow concentrations were higher than PDB concentrations for each detected metal. The five wells with well-purge/low- flow samples described as “clear” generally had better agreement between well-purge/low-flow and PDB metals concentrations. Based on these observations, it appears likely that the well- purge/low-flow metals results form DMW-A were influenced by turbidity, leading to higher metals concentrations. In this case, it appears likely that the PDB metals results are actually more representative of groundwater concentrations in DMW-A than well-purge/low-flow results because turbidity effects are reduced. 4.2.1 Evaluation of False Positive Data Pairs As shown in Table 4, there are three False Positive results; chlorobenzene and trichloroethene in DDW-01, and lead in YRW-10C. Each of these results had a PDB concentration close to the laboratory Estimated Quantitation Limit (EQL) for the analyte in question, and were of relatively ORZPDJQLWXGHȝJ/. Additionally, the False Positive results demonstrate the ability of Dual-Membrane PDBs to detect constituents that are present in groundwater that were not detected using well-purge/low-flow sampling. 4.2.2 Evaluation of False Negative Data Pairs As shown in Table 4, there are six False Negative results: all of which involved a metal analyte being detected in the well-purge/low-flow samples, but not the PDB sample. These False Negative data pairs are examined in greater detail below: x DDW-01 (Manganese), DMW-01 (Cadmium, Chromium [III+VI]), DMW-02A (Lead): Each of these detections in the well-purge/low-flow samples was close to its laboratory EQL, and therefore relatively small variability in concentrations could lead to non- detection. x DMW-06 (Iron): The well-purge/low-flow detection of 98.1 ȝJ/LVQHDUO\DQRUGHURI magnitude larger than its EQL. This result indicates that the iron concentration from PDB sampling in this well was likely not representative of actual groundwater conditions. Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 8 GC5699A\FINAL Appendix B - GW Sampling Comparison Study.docx One possible explanation is that chemical reactions could have occurred which led to changes in the iron concentration within the PDB. For example, redox chemistry changes could lead to precipitation of iron, which could reduce the dissolved iron concentration in the PDB. The well-purge/low-flow iron concentration in this well was below its 2L Standard of 300 ȝJ/ x DMW-A (Chromium [III + VI], Manganese): Detections for both of these constituents in the well-purge/low-flow sample are an order of magnitude larger than their EQLs. As previously discussed, turbidity may have influenced metals concentrations in the well- purge/low-flow sample in DMW-A, and the lower metals concentrations from the PDB sample may be more representative of groundwater conditions in this well. 4.2.3 Evaluation of Both Detect Data Pairs Table 5 presents the Both Detect data pairs and the RPD between the two samples in each pair. Figure 2 presents the PDB data plotted as a function of the well-purge/low-flow sample results for each of the constituents detected with both sampling methods. A line representing 1:1 correlation of well-purge/low-flow and PDB sample results is shown on the figure for comparison. The figure illustrates that the analytical results obtained using the PDB samplers are generally well correlated to the well-purge/low-flow sampling results. A clear bias with higher or lower concentrations using one sampling method is not evident. Several apparent outliers are present, which are discussed below. Both Detect data pairs with sample results exhibiting a RPD less than 30% were considered to compare well. Calculated RPD values greater than 30% were evaluated in further detail for potential biases. As discussed in the ITRC guidance document, RPD values between duplicate samples collected using the sample sampling method can be high, and comparisons between sampling methods should be considered in this context. RPD values greater than 30% for this comparison are not necessarily indicative of failure of the PDB sampling method, but rather indicate the need to consider the possible causes of the variability. Of the 35 Both Detect data pairs, 32 had RPDs of 30% or less, or had PDB results which were higher than the associated well-purge/low-flow results (indicating a conservative result of the PDB sampling method in the well), or had results in which both the PDB and the well-purge result were both less than 5 μg/L (indicating that the high degree of variability is influenced by the small relative differences in concentrations at this level). The remaining Both Detect sample pairs which fall outside these three criteria are examined in closer detail below. Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 9 GC5699A\FINAL Appendix B - GW Sampling Comparison Study.docx x DMW-06 (manganese): This data pair has a well-purge/low-flow result of 172 ȝg/L and D3'%UHVXOWRIȝJ/Although the PDB manganese concentration was lower than the well-purge/low flow manganese concentration, it is within the range of historical detections at this well (as shown in Table 3-4). x DMW-A (barium): The well-purge/low-flow result was ȝJ/and the PDB result was ȝJ/. While the PDB result is within the range of historical detections at this well, it is lower than detections during recent sampling events, and the well-purge/low flow result consistent with recent trends. This result indicates that the barium concentration from PDB sampling in this well was likely not representative of actual groundwater conditions. However, the results are both within the same order of magnitude and are well below the 2L standard for barium. x DMW-A (iron): The iron detection in the PDB sample at DMW-A (65.4 ȝJ/is two orders of magnitude below its corresponding well-purge/low-flow result ȝJ/. As previously discussed, turbidity may have influenced metals concentrations in the well- purge/low-flow sample in DMW-A, and the lower metals concentrations from the PDB sample may be more representative of groundwater conditions in this well. Collectively, the results of Both-Detect compounds compare well for most data pairs, including VOCs and metals. Several discrepancies with the metals results discussed above may result from difficulty for metals to reach equilibrium with groundwater in some conditions. However, in cases where turbidity may be affecting well-purge/low-flow metals results, the lower PDB metals concentrations may be more representative of aquifer conditions. CONCLUSIONS AND RECOMMENDATIONS A groundwater sampling comparison study between dual-membrane PDB and low-flow/well- purge sampling methods was conducted at the Former York Road Landfill with a goal of evaluating the PDB sampling method as an alternative for use in long-term monitoring at the Site. This evaluation demonstrated that the PDB sampling technology generally provides analytical data for Site constituents that are representative of aquifer conditions at the wells evaluated based on a side-by-side comparison with well-purge/low-flow sample results and in consideration of historical groundwater trends. Out of a total of 336 data pairs including both VOCs and metals, 326 data pairs were either Both Detect of Both Non-Detect. The 10 data pairs that were either False Negative or False Positive were generally low values close to the estimated quantitation limit, or may have been influenced by turbidity. Variability between analytical data generated using both sampling methods was generally low. Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 10 GC5699A\FINAL Appendix B - GW Sampling Comparison Study.docx Metals PDB sample results compared less favorably to their well-purge/low flow counterparts than VOC PDB results, and may have been influence by effects from turbidity and/or chemical reactions. The high degree of pumping stress associated with the well-purge/low-flow sampling technique relative to PDB sampling can induce turbidity into samples that can increase metals concentrations. In these cases, PDB metals samples may be more representative of groundwater conditions than well-purge/low-flow metals samples. Select False Negative metals data pairs could have resulted from chemical reactions such as iron precipitation within the PDB, a phenomenon which has been observed in Dual Membrane PDBs but is not yet fully understood. These exceptions are not so significant that data quality objectives of groundwater sampling at the Site are not met, but the potential limitations of metals sampling using this technology should be considered when evaluating groundwater data collected using PDBs. Based on the results of this evaluation, it is recommended that future Site groundwater monitoring activities for VOCs and metals be conducted using dual-membrane PDB sampling. This sampling method provides the advantages of decreased liquid IDW generation and lower sampling effort, while still providing quality groundwater data. Long term trends in VOC and metals data at the Site should be evaluated in the context of a change in sampling methodologies to PDBs upon implementation of this change. 6.

GC5699A\FINAL Appendix C - Pilot Study Report.docx Memorandum Date: 31 May 2016 To: Ms. Jaclynne Drummond – NCDEQ DWM SWS From: Copies to: David Hanley, P.E. and Jeffrey M. Ahrens, P.E. - Geosyntec Doug Pierotti – City of Charlotte Subject: Technical Memorandum – Northeast Boundary Landfill Gas Extraction System Pilot Test Former York Road Landfill, Charlotte, North Carolina 1. INTRODUCTION On Behalf of the City of Charlotte, Geosyntec Consultants of NC, PC (Geosyntec) is providing this report to summarize the methods and results of a pilot test to evaluate the potential effectiveness of a supplemental, in-soil, perimeter gas extraction system along the northeast (NE) boundary at the Former York Road Landfill (the Site). This pilot test represents the next step in the phased approach to address possible methane migration in the NE boundary area. This pilot study was carried out with the purpose of evaluating the use of active extraction well points in the soil screened below the depth of the existing extraction system’s trench to prevent off-Site migration of landfill gas. 2. BACKGROUND Occasional detections of methane in off-Site subsurface probes near the NE boundary have indicated that methane migration past the existing NE boundary extraction system may be occurring. Methane measurements in the vicinity of the trench extraction system have indicated that a methane migration pathway may be present in the subsurface between the bottom of the trench (approximately 17 feet below ground surface [ft bgs]) and the water table (approximately 20 to 40 ft bgs). Also, vacuum measurements in probes located outside and in the immediate vicinity of the extraction trench indicate that the current extraction system is not typically providing vacuum influence to these areas. These findings were supported by the results of recent investigative activities including a temporary surface liner pilot study and installation of Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 2 GC5699A\FINAL Appendix C - Pilot Study Report.docx three piezometers, which were installed to gain a better understanding of subsurface lithology and hydrogeology. In consideration of the information gathered during pilot study activities and piezometer installation, Geosyntec’s recommended path forward was to evaluate alternative mitigation options to address the methane migration pathway in the subsurface at depths below the trench and above the water table. Geosyntec recommended that the City consider investigating the use of active extraction well points in the soil screened below the depth of the trench to prevent migration across this interval. The newly installed piezometers presented an opportunity to evaluate the use of active extraction wells because they are partially screened in the unsaturated zone. A pilot-scale evaluation was conducted by applying vacuum to recently installed piezometer NEB-PZ-2 and monitoring the extracted gas and vacuum influence in the subsurface. The remainder of this document presents the procedures and results of this pilot test. 3. VACUUM MONITORING PROBE INSTALLATION During the 19 January 2016 pilot test, the piezometer NEB-PZ-2 was used as an extraction point to collect vapors from the subsurface. This piezometer was selected to be used as an extraction well during this pilot test because of its location and design. NEB-PZ-2 is located in the vicinity of possible methane migration along the NE boundary. The piezometer is screened with approximately 10 ft of screened length extending above the water table during typical conditions. The top of the screen is approximately 2.5 ft deeper than the reported bottom of the trench. These design factors will allow for collection of vapors from the unsaturated zone below the bottom of the extraction trench and are similar to what may be used in the design of a full-scale extraction system. During the pilot test, vacuum levels in the subsurface surrounding NEB-PZ-2 were monitored to evaluate the vacuum radius of influence of the pilot extraction system. For this purpose, vacuum monitoring probes (VMPs) were installed at varying distances from the extraction point prior to implementation of the pilot test. Three VMPs (VMP-01, VMP-02, and VMP-03) were installed at locations shown on Figure 1 at distances of 8, 16, and 24 feet from NEB-PZ-2. Based on Geosyntec’s experience with vapor extraction systems at sites with similar piedmont geology, the extent of vacuum influence within the subsurface was expected to fall within this range. VMPs were installed using hollow stem auger (HSA) drilling methods on 8 January 2016 by Geologic Exploration, Inc. under observation by Geosyntec. Construction logs for VMPs are included as Attachment A. VMPs were constructed of 1-inch diameter Schedule 40 PVC riser and screen. VMPs were installed to depths of 30 to 31 ft bgs, corresponding to the approximate top of the water table as observed following NEB-PZ-02 installation, with 10-ft screened lengths. The VMP well screens have a slot size of 0.020 inches. Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 3 GC5699A\FINAL Appendix C - Pilot Study Report.docx A sand filter pack consisting of coarse #3 sand was installed in the annulus around the screen to a height of 2 to 2.5 ft above the top of the screen. A 2-ft thick bentonite seal was placed above the sand pack and the remainder of the borehole annulus was grouted to the surface with neat cement grout. The wells were completed with a well cap and an 8-inch diameter bolt-locking traffic- rated manhole within a 2 ft by 2 ft concrete pad. 4. PILOT TEST PROCEDURES Vapor extraction pilot testing activities were conducted at the Site on 19 January 2016 utilizing a trailer mounted extraction system suitable for the generally low-permeability soil type in the unsaturated zone at the Site. Pilot testing equipment included a Roots URAI 22 Positive Displacement (PD) Blower with a 3 hp, 3450 RPM, 115/230V, 29/14.5 amp, 60 hz Baldor electric motor capable of providing up to approximately 163 inches of water column (in w.c., equivalent to 12 inches of mercury) vacuum; an in-line air filter; moisture separator; vacuum and pressure gauges. This system was constructed with explosion-proof equipment and run from a 15 kW generator. Pilot system components were mounted on a trailer placed adjacent to NEB- PZ-2. During the test, vacuum was provided to NEB-PZ-2 via a hose connection to the pilot test system. A step test was conducted by providing vacuum at five vacuum levels ranging up to the maximum possible vacuum available from the system blower. Each vacuum step continued for a duration of approximately one to two hours. During the performance of the pilot test, the following information was collected and recorded on the field testing form: x testing start/finish time; x weather conditions during testing; x extracted air velocity; x applied wellhead vacuum; x vacuum response at nearby VMP locations and select nearby gas probes, recorded using digital manometers and/or magnehelic gauges; x landfill gas concentration measurements of extracted air at the NEB-PZ-2 wellhead, at VMPs, and at select nearby gas probes using a handheld landfill gas monitor (Landtec GEM 2000); x atmospheric pressure readings using the handheld landfill gas monitor; and x volume of fluid condensate recovered during the performance of the pilot test. Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 4 GC5699A\FINAL Appendix C - Pilot Study Report.docx The probes monitored for vacuum and landfill gas during the pilot test were: x VMP-01 (screened from 21 to 31 ft bgs), VMP-02, and VMP-03 (both screened from 20 to 30 ft bgs); x GP-4S and GP-4D, located approximately 20 feet (estimated) from NEB-PZ-02 and on the opposite side of the extraction trench. These probes are both believed to be screened within the range of 20 to 30 ft bgs based on historical documents; x MP-32, located approximately 60 feet (estimated) from NEB-PZ-02 in the direction of the landfill waste boundary (southwest) with a total depth of approximately 17 ft bgs; x SU-2, an active extraction well screened within the trench, located approximately 30 feet (estimated) from NEB-PZ-02, to the northwest; x SU-8, an active extraction well screened within the trench, located approximately 150 feet (estimated) from NEB-PZ-02, to the southeast; x An Unidentified Probe located within an 8-inch diameter flush-mount vault approximately 64 feet southeast of NEB-PZ-02, and on the same side of the extraction trench as NEB-PZ-02, with a measured total depth of 32.5 ft bgs and a depth to water of approximately 31 ft bgs. Baseline readings of vacuum and landfill gas concentrations were monitored prior to initiating the pilot test, and again after the conclusion of the pilot test. Extraction was initiated at 10:35 and was carried out continuously until shutdown at 16:40. 5. PILOT TEST RESULTS Operational data collected during pilot testing is presented in Table 1, and measurements from nearby monitoring probes are presented in Table 2. The results are depicted graphically in Figures 2 through 4. A photographic log of pilot testing activities is included as Attachment B. The results are summarized as follows: x Weather conditions observed during the pilot test were cold, with a low temperature of 14°F during the morning and warming up to a maximum temperature of approximately 36°F. The ground was observed to be frozen during the morning. Conditions were clear and sunny throughout the test. x Atmospheric pressure was observed to increase during the morning from approximately 09:00 until system startup at 10:35 and then decrease until approximately 13:00, where it remained level for the duration of the test. A single atmospheric pressure reading taken after system shutdown indicated another increase had occurred. Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 5 GC5699A\FINAL Appendix C - Pilot Study Report.docx x Baseline readings indicated that the VMPs and nearby probes GP-4S and GP-4D were under vacuum prior to system startup. Vacuum conditions were likely a result of increasing atmospheric pressure at the time of measurement. It is also theorized that vacuum influence from the active extraction trench may have been observed in these probes and VMPs. It is notable that vacuum conditions have not been previously observed in probes GP-4S and GP-4D during Geosyntec’s investigation activities. However, the existing system could have been enhanced by the frozen ground conditions limiting air intrusion in the trench and improving its radius of influence in the subsurface. x Active extraction at NEB-PZ-2 was initiated at 10:35, and the first three vacuum steps resulted in wellhead pressures of approximately 10, 26, and 50 in w.c. and flow rates around 6, 10, and 16 standard cubic feet per minute (SCFM, with standard conditions of 1 atmosphere and 25°C). During these three vacuum steps, vacuum levels in VMPs, GP- 4S, and GP-4D were observed to steadily decrease until slightly positive pressures were observed in each. The decrease in vacuum levels is likely attributable to decreasing atmospheric pressure during this time interval (and possible thawing of the ground surface and reduced influence from the extraction trench system). The decreases in vacuum levels and subsequent positive pressures in these probes indicates that active extraction from NEB-PZ-2 did not have measurable influence in these probes during the first three vacuum steps. x The fourth and fifth vacuum steps operated at approximately 100 and 135 in w.c., with flow rates around 23 and 25 SCFM, respectively. During these steps, vacuum levels in the three VMPs, GP-4S, and GP-4D increased, reaching a maximum of 0.51 in w.c. measured at VMP-01. This increase is evidence of influence from the pilot test extraction well. Additionally, vacuum levels were observed to be higher with increasing proximity to the extraction well, providing further evidence of influence from the extraction well. Atmospheric pressure remained constant throughout this time interval. x One additional round of vacuum monitoring was conducted at the end of the pilot test after extraction was stopped. At this time, vacuum levels in VMP-01 and VMP-02 dropped, while VMP-03, GP-4S, and GP-4D remained relatively stable. This suggests that vacuum influence was largest in VMP-01 and VMP-02 (the two closest probes), and it is uncertain whether VMP-03, GP-4S, and GP-4D were actually influenced by the extraction well or perhaps by changing atmospheric conditions (atmospheric pressure increased after system shutdown). Other probes (i.e. MP-32 and the Unidentified Probe) that were more distant from the extraction well did not exhibit clear trends that would suggest influence from the extraction well. x Methane levels in the extracted vapor from NEB-PZ-2 initially measured 13.2% at system startup. The methane concentration increased during the morning and peaked at Groundwater Sampling Methodology Comparison Study 31 May 2016 Page 6 GC5699A\FINAL Appendix C - Pilot Study Report.docx 31.7% at 12:45 before decreasing to sustained levels around 0.3% in the afternoon. GP-4S and GP-4D followed similar trends in methane levels, first increasing to a maximum of 52.2%, and then decreasing substantially at higher vacuum extraction levels. The three VMPs had very low methane concentrations throughout the pilot test, ranging from 0.1% to 0.3% methane. x The active extraction trench system continued operating during pilot testing, and the two closest extraction points, SU-2 and SU-8, were monitored periodically. Vacuum levels, methane levels, and flow rates at these wells were observed to be typical for this system compared to historical operational observations. 6. CONCLUSIONS The results of the pilot test indicate that a measurable vacuum influence was observed as far as 16 to 20 feet away in a direction parallel to the extraction trench at a wellhead vacuum of approximately 135 in w.c. While the vacuum levels induced were relatively low (around 0.5 in w.c.), this magnitude of vacuum is considered to be sufficient to induce air flow toward the extraction well based on experience with similar systems. The results of the pilot test confirmed the capability of a wellpoint vapor extraction system located between the existing extraction trench and the landfill to provide vacuum influence in the interval below the bottom of the trench and above the water table. The pilot test results are encouraging that a reasonable radius of influence can be achieved and methane capture and removal from this interval is possible. ***** TABLES Ta b l e 1 : E x t r a c t i o n L o g No r t h e a s t B o u n d a r y P i l o t T e s t Fo r m e r Y o r k R o a d L a n d f i l l Ge o s y n t e c C o n s u l t a n t s o f N C , P C Pa g e 1 o f 1 February 2016 Da t e / T i m e Ex t r a c t i o n We l l S t a r t u p E x t r a c t i n g S h u t d o w n Ai r F l o w Ra t e (f p m ) Ai r F l o w Ra t e ( s c f m ) Ap p l i e d Va c u u m a t Bl o w e r (in H g) Di s c h a r g e Pr e s s u r e (p s i ) In l e t A i r Te m p .
