Ten wells (MW-17, MW-18, MW- 19, MW-20, MW-21, MW-22, MW-23, MW-24, MW-25, and MW-25D) comprise the groundwater monitoring system for the lined Subtitle D solid waste disposal area of the landfill, also known as Phase III. Monitoring wells MW-15 and MW-16 serve as background wells for Phase III. The collected samples were submitted to a North Carolina certified laboratory for analysis using the federal Appendix I list of volatile organic and inorganic constituents for detection monitoring. Samples from surface water locations SW-1, SW-2, SW-3, and SW-4 were analyzed for federal Appendix I detection monitoring constituents. The following summarizes the findings for this event. ♦Groundwater sample analyses detected no Appendix I volatile organic compounds at the sampled locations, except for an estimated concentration of 2-Butanone at background well MW-15. ♦Groundwater sample analyses report no Appendix I inorganics at concentrations which exceed the corresponding NCAC 2L groundwater quality standards. Cobalt and vanadium were detected in groundwater samples. Since there are no established NCAC 2L standards for these metals, the results were compared with the North Carolina, Interim Maximum Allowable Concentrations (IMAC). The cobalt concentration at well MW-24 was greater than the corresponding IMAC. The vanadium concentrations reported at wells MW-17, MW-19, MW-20, MW-23, and MW-25b were greater than the corresponding IMAC. Time vs concentration plots for cobalt and vanadium were examined and do not suggest trends of increasing concentrations over time, most suggest generally stable concentrations over time. These findings provide a line of reasoning that supports the natural occurrence of these metals at the Facility. The Phase III Alternate Source Demonstration (ASD) for metals also supports this finding. ♦The groundwater analytical results were examined for evidence of statistically significant increases (SSIs) over background values. The statistical tests suggest that no SSIs occurred during this groundwater monitoring event. This finding was further supported by a review of time vs concentration graphs prepared for the detected constituents, which revealed no evidence of increasing concentrations over time. Based on a finding of no SSIs, the reported concentrations were not considered indicative of a release from the monitored unit. ♦Three Appendix I volatile organic compounds and seven inorganic constituents were detected in one or more of the surface water samples collected. No 2B Standards associated with the Water Supply (WS) stream classification were exceeded, except for copper which was detected up- stream and down-stream at relative similar concentrations, thus we infer it is not from the Facility. An ASD for metals was previously completed for the adjoining Phase II portion of the Facility. The results of the ASD advocate that cobalt and vanadium concentrations reported above the respective IMAC values were not likely due to a release by the Facility, but instead may be attributed to the natural occurrence of these metals in the native, residual soil at concentrations sufficient to influence the concentrations in groundwater. Although undertaken for Phase II of the Facility, the ASD results were likely applicable to Phase III. During 2016, an ASD was developed for metals detected in shallow groundwater in the vicinity of Phase III. The Phase III ASD also found cobalt and vanadium as naturally occurring in shallow groundwater. The Phase III ADS was submitted to the NCDEQ-SWS for their review and approval. White Street Landfill - Phase III (Permit # 41-12) Detection Monitoring Report Greensboro, North Carolina S&ME Project No. 1584-98-081C January 11, 2017 2 2.0 Introduction White Street Landfill is a Solid Waste Management Facility (SWMF) located at the north end of White Street in northeastern Greensboro. The City of Greensboro operates this lined Subtitle D landfill, referred to as Phase III, under Solid Waste Permit #41-12. Ten wells (MW-17, MW-18, MW-19, MW-20, MW-21, MW-22, MW-23, MW-24, MW-25, and MW-25D) comprise the groundwater monitoring system for the lined Subtitle D solid waste disposal area of the landfill. Monitoring wells MW-15 and MW-16 serve as background wells for Phase III. The monitoring well locations are shown on Figure 1 S&ME, Inc. (S&ME) was contracted by the City of Greensboro to conduct this semi-annual water quality monitoring event. Groundwater samples were collected from two up-gradient and nine down-gradient monitoring wells located along the perimeter of the Phase III disposal area. Surface water samples were collected at surface water location SW-1, SW-2, SW-3 and SW-4. Sampling was conducted in accordance with the approved site Water Quality Monitoring Plan. The Phase III monitoring well samples were analyzed for the RCRA Subtitle D Appendix I parameters. The surface water samples were also analyzed for the Appendix I list of constituents. This report discusses the field procedures, summarizes the field measurements and analytical results, and presents the statistical evaluation results for the September 2016 water quality monitoring event. 3.0 Scope Of Work S&ME completed the following tasks as part of this monitoring event: ♦Sampled eleven monitoring wells and four surface water locations. ♦Obtained field values for pH, temperature, conductivity, dissolved oxygen (DO), oxidation- reduction potential (ORP), and turbidity at each groundwater sample location. ♦Collected depth to water measurements prior to sampling and during well purging to monitor drawdown. ♦Samples were analyzed for Appendix I constituents by a North Carolina certified laboratory using State approved methods. ♦Assessed groundwater flow rates and directions at the Phase III area monitoring well locations. ♦Collected a sample of landfill leachate from the wet well for laboratory analyses. ♦Prepared and submitted reports to the City of Greensboro and the North Carolina Department of Environmental Quality, Division of Waste Management, Solid Waste Section (NCDEQ-SWS). 4.0 Methods Employed 4.1 Monitoring Well Sampling On September 27 and 28, 2016, monitoring wells MW-15, MW-16, MW-17, MW-18, MW-19, MW-20, MW-21, MW-22, MW-23, MW-24, and MW-25b were sampled. The water level observed in monitoring well MW-25 was near the pump; therefore, it was not sampled. Prior to sampling, each well was opened and the static water level was measured from the top edge of the PVC casing. Since dedicated MicroPurge pumps were previously installed in each groundwater monitoring well as described in the White Street Landfill - Phase III (Permit # 41-12) Detection Monitoring Report Greensboro, North Carolina S&ME Project No. 1584-98-081C January 11, 2017 3 monitoring well construction details reported in the “Baseline Groundwater Monitoring Report, Phase III” prepared by G.N. Richardson and Associates, dated May 1998, low-flow sampling techniques were used for groundwater sample collection. Monitoring well construction details from the same report were used to determine the volume of water in the monitoring wells.Table 1 provides a summary of well construction details. At each well, the purge rate and the water level drawdown were monitored as an indicator of how much stress the purging placed on the aquifer. The purge rates were calculated by recording the time required to fill a graduated cylinder. The purging flow rates were approximately 100 milliliters/minute (ml/min.). During purging, the depth to water was periodically monitored and recorded on the field data sheets. For this event the measured drawdown in the sampled wells was generally less than 3 feet. It is our opinion that the observed drawdowns were generally minor during purging; therefore, the stresses placed on the aquifer should have been minor. The observed drawdown data suggests that the purging rates should have been low enough such that recharge water should not have been overly agitated, reducing the potential for colloids to be drawn into the well bore. The purge water from the monitoring wells was monitored in the field for pH, temperature, conductivity, DO, and ORP using a flow-through cell and multi-meter. Typically, a sample was collected when three consecutive readings for each individual field parameter fluctuated by no more than 10 percent, between each equipment volume. The 10% change target stabilization goal was generally reached prior to collection of the groundwater samples. Turbidity was measured separately, with field measurements less than or equal to 10 NTUs, as a goal. Even with the use of low flow sampling methods, turbidity values at some wells remained higher than ideal during purging. Accordingly, some samples were collected based upon professional judgment without meeting the turbidity goal. The field data collected during sampling was recorded on the groundwater sampling field data sheets included in Appendix I.Table 2 provides a summary of the field data collected during this event. Groundwater samples were collected from the dedicated pump discharge Teflon tubing at the top of each well. Upon collection, each sample was placed into laboratory supplied containers, placed in a cooler with ice, and placed under chain-of-custody. The sampling technician wore nitrile gloves, which were changed between wells to reduce the potential for cross contamination. The groundwater samples collected were analyzed for Appendix I volatile organic and inorganic constituents. Analyses were conducted by Environmental Conservation Laboratories, a North Carolina certified laboratory. 4.2 Statistical Analysis of Data 4.2.1 Software The groundwater analytical data were analyzed using ChemStat 6.2 software package. An Excel spreadsheet was used to create a data file composed of recent and historic laboratory data. The Excel file was then converted to a tab delimited file for use by the ChemStat software. The following procedures were used to carry out statistical analyses of the data for each constituent detected during this monitoring event. White Street Landfill - Phase III (Permit # 41-12) Detection Monitoring Report Greensboro, North Carolina S&ME Project No. 1584-98-081C January 11, 2017 4 4.2.2 Statistical Methods-Groundwater Analyses In accordance with the NCDEQ-Solid Waste Management Rules 15A NCAC 13B, Section 1632, historical up-gradient, cross-gradient, and background groundwater monitoring data collected from the monitoring wells that comprise the Subtitle D monitoring well system were pooled and the analytical results were used to create a statistical baseline for statistically significant increases in constituent concentrations. This sampling round (September 2016) will be incorporated into the database for the next round of sampling. The following procedure was used to analyze each new data set. ♦A descriptive statistics were run to provide mean, standard deviation, variance, and percentage non-detects. ♦Normality/Data Distribution Tests were run and used to determine the statistical distribution of the database for each quantified parameter. The data distribution test results were utilized to determine if a data set exhibits a normal, log-normal or non-normal distribution. Due to the large number of non-detects and the lack of normality in the data sets, non-parametric statistical methods were deemed appropriate for the evaluation of the current compliance data set. ♦Time versus concentration graphs were prepared for each parameter detected at a quantifiable concentration and used to evaluate data trends and to identify potential data outliers. If further trend analysis was warranted, Mann-Kendall Trend analyses were performed as additional tests for indications of an upward trend of concentrations over time. ♦Non-Parametric Prediction Interval tests were employed to determine if any individual parameter concentration detected during this monitoring event represents a Statistically Significant Increase (SSI) over the historic background concentrations. For all statistical analyses, the non-detect values were converted to the respective Detection Limit for data analysis. ♦If data indicated a statistically significant increases across the site, the results are examined to determine the validity of results. 4.3 Stream Sampling Surface water sampling took place on September 26, 2016. Three stream samples (SW-1, SW-2, SW-3, and SW-4) were collected in accordance with the approved site Sampling and Analysis Plan. The stream sample locations are indicated on Figure 2. The surface water samples were collected by immersing laboratory-supplied containers in the water to be sampled. After collection, the surface water samples were placed in a cooler with ice and managed under chain-of-custody. All stream samples were analyzed for Appendix I constituents by Environmental Conservation Laboratories. 5.0 Results 5.1 Groundwater Analytical Results Table 3 provides a summary of the constituent concentrations reported above the method detection limit (MDL) for the groundwater samples collected. Concentrations reported between the MDL and the Solid Waste Section Limits (SWSL) are considered estimated, thus shown as a “J” flagged concentration.Table 4 provides a summary of the reported concentrations which appear to exceed the 15A NCAC 2L Standards (2L Standard). For some constituents where there is no established 2L Standard, North Carolina has published Interim Maximum Allowable Concentrations (IMACs). The IMAC values are intended to help White Street Landfill - Phase III (Permit # 41-12) Detection Monitoring Report Greensboro, North Carolina S&ME Project No. 1584-98-081C January 11, 2017 5 NCDEQ-SWS in assessing conditions and setting health protective groundwater levels at regulated sites. As such the IMAC are only interim and not final groundwater quality standards. The following summarizes the apparent exceedances of the corresponding 2L Standard or IMAC. Appendix I volatile organic compounds ♦No Appendix I volatile organic compounds were detected during this monitoring event, except for 2-butanone detected at background monitoring well MW-15. The detected concentrations was below the corresponding 2L Standard. Appendix I metals Appendix I metals barium, chromium, cobalt, copper, nickel, vanadium, and zinc were detected at one or more of the wells sampled. Many metals occur naturally in groundwater; consequently, the 2L Standards contain a provision to exempt naturally occurring metal concentrations. Thus a direct comparison of detected concentrations to these benchmarks is not conclusive evidence of an exceedance. The following lists constituents with concentrations that appear to exceed the corresponding 2L Standards or IMACs. ♦There is no established 2L Standard for cobalt; however, North Carolina has a published IMAC established at 1 µg/L. Cobalt concentration reported at well MW-24 was greater than the corresponding IMAC. ♦There is no established 2L Standard for vanadium; however, North Carolina has published an IMAC established at 0.3 µg/L. Vanadium concentrations reported at wells MW-17, MW-19, MW- 20, MW-23, and MW-25b were greater than the corresponding IMAC. The complete laboratory analytical reports are included in Appendix II. 5.2 Statistical Results 5.2.1 Overview of Database The “Baseline Groundwater Monitoring Report, Phase III Cell, White Street Sanitary Landfill,” prepared by G.N. Richardson & Associated, dated June 1998, summarizes the baseline monitoring data. The baseline monitoring samples were collected using the hand bailing procedures outlined in the approved Water Quality Monitoring Plan. Prior to the October 1998 monitoring event, but subsequent to the Baseline Groundwater Monitoring Report, the facility’s approved Water Quality Monitoring Plan was modified to permit the use of dedicated MicroPurge pumps for monitoring well sample collection. The statistical evaluations discussed herein were only performed on parameters detected during the subject monitoring event. In this statistical evaluation, non-detects are assigned values equal to their respective detection limits. This method of handling non-detects was used as part of the statistical analyses completed as part of the baseline water quality monitoring evaluations as set forth in the NCDEQ-SWS memo dated January 18, 1995. White Street Landfill - Phase III (Permit # 41-12) Detection Monitoring Report Greensboro, North Carolina S&ME Project No. 1584-98-081C January 11, 2017 6 5.2.2 Statistical Analyses 5.2.2.1 Descriptive Statistics The descriptive statistics program calculates the pooled mean, background mean, pooled standard deviation, background standard deviation, rank sum, rank mean, and variance for each constituent detected in each well. The percentages of all sample analyses for which the concentrations are below the quantitation limits (non-detects) are calculated by constituent for each well. 5.2.2.2 Time vs. Concentration Graphs The graphs display plots of the concentrations of one parameter for a single well over time. The concentration is plotted along the vertical axis and the sample dates are plotted along the horizontal axis. The graphs were used to visually examine changes in concentration over time for a parameter at a given well. Graphs were only prepared for parameters detected at a given well, during this monitoring event. The graphs are contained in Appendix III. ♦The time series plots of barium concentrations at background wells and compliance wells illustrate consistent non-detections of barium prior to the promulgation of the lower SWSLs. The post 2006 data sets generally exhibits relatively stable concentrations over time. ♦Time series plots of chromium concentrations at well MW-25b depict consistent detections following the change to a lower SWLS. The majority of the detections were estimated values. The detected concentrations depict reasonably stable concentrations over time. ♦Time series plots of cobalt concentrations at well MW-24 depict periodic detections following the change to a lower SWLS. The majority of the detections were estimated values. The detected concentrations depict reasonably stable concentrations over time. ♦The time series plots of copper concentrations at each compliance well and background well MW- 15 depict consistent non-detections of copper prior to the revised SWSL. The majority of the detections were estimated values. The post 2006 data set for each well generally exhibit relatively stable concentrations over time. ♦The time series plots of the concentrations of nickel at compliance wells MW-16, MW-21, and MW-24 generally illustrate no detections of nickel prior to the revised SWSL. The majority of the detections were estimated values that exhibit an overall trend of stable concentrations over time. ♦The time series plots of vanadium concentrations at compliance wells MW-17, MW-19, MW-20, MW-23, and MW-25b illustrate no detections prior to the revised SWSL. The detections coincide with the revised SWSL, with most detections qualified as estimated values. The post 2006 data sets depict trends of relatively stable concentrations over time. The time series plots of the concentrations of zinc at compliance wells MW-16, MW-17, MW-18, MW-19, MW-20, MW-21, MW-22, MW-24, MW-25, and MW-25b illustrate that the majority of the detections coincide the revised SWSL, with detected concentrations qualified as estimated values. The post 2006 data sets generally depict relatively stable concentrations over time. 5.2.2.3 Interwell Statistical Comparisons Non-parametric Upper Tolerance Intervals were calculated from the background data set to determine if any detected individual compliance parameter concentration represents a statistically significant increase White Street Landfill - Phase III (Permit # 41-12) Detection Monitoring Report Greensboro, North Carolina S&ME Project No. 1584-98-081C January 11, 2017 7 over the historic background concentrations. This test compares the current sampling event analytical data for each compliance well to Upper Limits computed from the pooled background data set. 5.2.2.4 Non-Parametric Prediction Interval Test In order to analyze the laboratory analytical results for evidence of statistically significant increases (SSIs) over background values, the data distribution of the detected monitored constituents was first analyzed. The data distribution tests indicated a non-parametric distribution for most wells and constituents, mostly due to a relatively high percentage of non-detects in the analyzed database. As a result, Non-Parametric Prediction Interval tests were employed to determine if any individual parameter concentration detected during this monitoring event represents a Statistically Significant Increase (SSI) over the historic background concentrations. The statistical analyses suggest that no SSIs occurred during this monitoring event. This finding is supported by the trend observation made of the time vs concentration graphs discussed in Section 5.2.2.2. 5.3 Hydraulic Conductivity In-situ hydraulic conductivity tests were performed by G.N. Richardson and Associates, Inc. (GNRA) on wells MW-16, MW-17, MW-18, MW-20, MW-21, MW-23, MW-25, during January 1998, with monitoring wells MW-15, MW-19, MW-22, MW-24, and MW-25D tested during March 1998. The data from these tests yielded hydraulic conductivity values ranging from 0.090 feet/day (in MW-24) to 3.269 feet/day (in MW-18). A complete discussion of the test methods and calculations was presented in the “Baseline Groundwater Monitoring Report, Phase III” prepared by G.N. Richardson and Associates, dated May 1998. The data summarized in Table 5 was used to calculate groundwater flow velocities for compliance network wells located at points around the perimeter of the monitored unit. 5.4 Groundwater Flow Direction and Rate The static water levels in the Phase III monitoring wells were measured on September 27 and September 28, 2016. The depth to the water table ranged from 3.71 feet to 27.63 feet below the top of well casing. Groundwater elevation, top of well casing elevations, and the monitored aquifer unit data for each well are presented in Table 1. A groundwater contour map was constructed using the data collected during this event and is presented as Figure 1. Based on the data collected, groundwater appears to be flowing north-northwest beneath the west half of Phase III and generally to the north-northeast in the eastern half of Phase III. The groundwater gradient at each well was calculated assuming a constant groundwater gradient along the flow line between adjacent up-gradient groundwater elevation contour line and the monitoring well. Based on a variation of Darcy’s Law, the rate of groundwater movement within the regolith aquifer was calculated at each monitoring well using the following equation: V = Ki ÷ n Where V = velocity (feet/day) K = hydraulic conductivity (feet/day) i = groundwater gradient (feet/foot) n =effective porosity (dimensionless) White Street Landfill - Phase III (Permit # 41-12) Detection Monitoring Report Greensboro, North Carolina S&ME Project No. 1584-98-081C January 11, 2017 8 Calculated hydraulic conductivity and gradient values and estimated effective porosity values for each well were used in the velocity calculations. The 20 percent effective porosity value is based on porosity and specific yield versus grain size distribution relationships presented in Fetter (1988), and is typical of the types of soils (predominantly silts and sandy silts with some clays) comprising the regolith at the landfill. The calculated groundwater velocities ranged from 0.008 feet/day at well MW-24 to 0.365 feet/day at well MW-25 and are summarized in Table 5. 5.5 Surface Water Table 6 provides a summary of the constituent concentrations reported above the method detection limit (MDL) for the surface water samples collected. Concentrations reported between the MDL and the Solid Waste Section Limits (SWSL) are considered estimated, thus shown as a “J” flagged concentration. The table also includes the corresponding 15A NCAC 2B Standard (2B Standard) for stream classified by NCDEQ as Water Supply (WS), if a WS standard is published. Three Appendix I volatile organic compounds were detected. Seven Appendix I metals were detected.Table 7 provides a summary of the reported concentrations which would appear to exceed the corresponding 2B Standard. The following summarizes the exceedances of the 2B Standards for this monitoring event. ♦No target constituents were detected above the 2B Standards during the September 2016 sampling event, except for copper. The copper concentrations upstream of the facility were similar to those detected down-stream. Immediate upstream sources include a municipal wastewater treatment plant. Based on these findings, the Phase 3 is not believe to be the source of the apparent copper 2B Standard exceedance. The complete laboratory analytical report is included in Appendix II. 5.6 Leachate Sample Analytical Results On September 26, 2016, a sample of leachate was collected from the leachate wet well. The collected sample was submitted for laboratory analyses for Appendix I constituents plus Nitrate, Sulfur, Sulfate, Phosphate, Biological Oxygen Demand and Chemical Oxygen Demand.Table 8 provides a summary of the associated analytical results. 5.7 Quality Assurance A qualitative review of the data was performed to verify that the detected concentrations in the laboratory report were of known quality. A formal, quantitative data validation was not performed. Laboratory- assigned data qualifiers were evaluated to verify that rejected or unsupportable data were not included in the dataset. Quality control data provided in the laboratory reports were also reviewed. No rejected or otherwise unacceptable quality data were reported from the laboratory. During this event a duplicate sample was collected from monitoring well MW-19 and submitted for analysis as "Duplicate III." This sample was analyzed for Appendix I constituents. The detected constituents and concentration reported for well MW-19 were similar to the concentrations reported in the sample labeled "Duplicate III" suggesting a good correlation between the paired analytical results.

These samples were analyzed for Appendix I volatile organic and inorganic constituents. No volatile organic or inorganic constituents were present in the trip blank samples at detectable levels. Laboratory QC samples were analyzed for all constituents included in this sampling event. The results of the duplicate, trip blank and laboratory QC sample analyses are included in Appendix II. 6.0 References Fetter, C.
