(MESCO) is pleased to present this Semi -Annual Water Quality Monitoring Report with Corrective Action Update for an event performed at the Alexander County active construction and demolition (C&D) and closed municipal solid waste landfill (MSWLF) between July 14-17, 2020. NCDENR Solid Waste Rules 15A NCAC 13B.1632 requires that Alexander County provide this report to the NC Solid Waste Section (SWS) on a semi-annual basis. Laboratory analytical results indicate that samples collected from 19 wells contained between one and four constituents above laboratory reporting limits and regulatory compliance Standards. Metal detections are believed to be naturally occurring. The source of VOCs is likely anthropogenic. VOC concentrations continue to decrease over time and distance. A metal was detected in an elevated concentration in three surface water samples. Corrective action to remediate VOCs in groundwater is ongoing within the four areas of concern (AOC) with updated information presented herein. A Corrective Action Evaluation Report (CAER) (DIN:27584) dated April 3, 2017 concluded groundwater quality has improved. The SWS approved that corrective action may continue as proposed and implementation of the contingency plan is not required. Background The Alexander County active C&D and closed MSWLF, is located at 2500 Paynes Dairy Road near Taylorsville North Carolina. The total waste footprint encompasses approximately 24 acres situated on 283 contiguous acres. The site location topographic map is depicted in the attached Sheet 1. The closed MSWLF ceased operation prior to 1998 and the C&D landfill continues operation on the eastern unit of the closed MSWLF. Both landfill areas are treated as a single unit in this report. Water quality has been monitored at this facility on at least a semi-annual basis since 1990. MESCO submitted two Assessment and Corrective Action (ACM) reports dated August 27, 2002 and April 11, 2008. MESCO then developed a Corrective Action Plan -Revision I (CAP -Rev 1) on February 6, 2009. In response to improved water quality and changing geochemical conditions the originally selected remediation approach was amended by MESCO in a Corrective Action Plan -Addendum (CAP -Add) dated December 20, 2010. Groundwater remediation efforts have been implemented at the four distinct areas of concern (AOCs) which are identified as MW-lB, MW-16, MW-24 and MW-26. Remediation technologies initiated to date with reference to their respective AOC include monitored natural attenuation (MNA) (MW-16, MW-24, MW-26), phytoremediation (MW-24), enhanced bioremediation via substrate injection (MW-26) and landfill gas (LFG) extraction (MW-1B). Following establishment of the two-year MNA baseline MESCO completed a CAER (DIN 13596) on March 22, 2011. Based on improved water quality conditions as demonstrated in the CAER the parameters and frequencies of future monitoring events were established by the SWS CAER review response (DIN 14150) dated June 16, 2011. A second CAP -Add was submitted by MESCO dated May 30, 2013 as requested by the SWS in a letter entitled Compliance Boundary (Relevant Point of Compliance) (DIN 18502) dated February 18, 2013. A Request for Appendix II Groundwater Monitoring Modification (DIN 20137) was submitted by MESCO dated November 8, 2013 which was subsequently approved by the SWS (DIN 20144) on November 13, 2013. A second CAER (DIN:27584) dated April 3, 2017 concluded that attenuation is occurring and no corrective actions other than what has already been initiated are planned at this time as approved by the NC SWS (DIN: 27678). 1 As specified within 15A NCAC 13B.16320), the SWS Environmental Monitoring Report Form and SWS memorandums this report contains sampling procedures, field and laboratory results, corrective action update, ground/surface water characterization, and findings. Well construction summary table, field observations table, field parameter data table, sampling and analysis summary table, detections compared to Standards tables, a groundwater flow directions/rates table, potentiometric map, time -series graph, quality assurance/quality control data, and laboratory analytical data results are enclosed herein. Sampling Procedures MESCO personnel performed this sampling event following the parameters and frequency established in the Water Quality Monitoring Plan (WQMP) dated August 11, 2016. The water quality monitoring program includes a combination of detection, assessment and corrective action monitoring with specifically defined analysis. Water samples were collected from all monitoring locations outlined in the CAP -Add and CAER with the exception of MW-IA; which has been chronically dry and two wells (MW-3 and MW-7) which are exempt from testing during the summer event. Monitoring locations are depicted on the potentiometric map (Sheet 2). Sampling was performed per the protocols outlined in the WQMP. A summary detailing the construction of the water monitoring wells is presented on Table 1. The function and integrity of all monitoring locations were visually evaluated as documented on Table 2. The depth to water in each well was electronically gaged prior to purging to quantify the static water level elevation. Submersible pumping or bailing was utilized to purge the wells a minimum of three times the volume of standing water in the well or until dry. Surface water samples were collected from previously designated locations along discharge features. During well purging and surface water sample collection the required field parameters were recorded. The samples were then placed into laboratory -prepared, pre -preserved containers via a new disposable polyethylene bailer. Samples were collected, kept on ice, and transported to a NC -certified laboratory under proper chain of custody (C-O-C) protocols and within the specified hold times for each analysis. Field Parameter Data Field parameters were recorded including depth to water, pH, specific conductance, temperature, hardness and turbidity. A summary of the field parameter data is presented in Table 3 and the field sampling data sheet is enclosed in Appendix A. Laboratory Results Pace Analytical Services Inc. (PACE) of Huntersville/Asheville, NC performed the laboratory analyses. Groundwater, surface water and quality control samples were tested for a mix of Appendix I paramaters, mercury and MNA performance constituents as prescribed in the approved water quality monitoring plan. Water samples were analyzed to the Method Detection Limits (MDL) and reported to the Reporting Limit (RL) which are both established by the laboratory. Any value above the adjusted MDL and below the RL was flagged as a "j-qualifier" which the laboratory defines as an estimated concentration. Estimated concentrations are considered non -quantifiable and discretion should be made prior to making decisions based solely on an approximate value. A sampling and analysis table summarizing the locations, laboratory, target analytes and methods is presented as Table 4. Laboratory results and C-O-Cs are presented in Appendix B. 2 Quality Control Samples Barium was detected in the EB sample. Barium was not detected above allowable Standards in any sample; therefore, the presence of the artifact contaminant is largely inconsequential. Groundwater Samples Detected Above Standards Table 5 summarizes constituents detected in groundwater and QC samples compared to groundwater compliance standards which include Interim Maximum Allowable Concentrations (IMAC) and North Carolina Groundwater Standards (2L). Although not applicable for regulatory compliance purposes the detections are also compared to the Maximum Contaminant Level (MCL) commonly referenced as the Federal "Drinking Water Standard". Metals One to three total recoverable forms of metals were detected above their respective RL and NC 2L Standard/IMAC Value in samples collected from 18 wells as summarized below. Metals Detected in Groundwater Samples Above RL and NC 2L Standard/IMAC Values Cadmium Chromium Cobalt Thallium Lead Mercury Vanadium 2L/IMAC 2 10 1 0.28 15 1 0.3 MW-1 8.7 MW-lB 53.9 2.3 MW-2 677 0.3 MW-4R 104 MW-6 8.6 MW-9 356 MW-11 123 MW-12 56.8 MW-12D 2.7 Mw-13 3.3 MW-14 157 38.8 304 MW-15 12.4 2.6 59 MW-16 272 MW-17 15 MW-19 3.5 MW-26 64.9 MW-33 8.1 MW-34 5.6 concentrations in ug/L 3 VOCs Benzene was detected above the RL and 2L Standard (1.0 ug/L) in samples collected from MW-5 (2.2), MW-9 (1. 1), MW-11 (2.6), MW-12 (1.4) and MW-15 (3.1). 1,4-dichlorobenzene was also found in sample MW-11 at 6.5 ug/L which is above the NC 2L Standard (6 ug/L). A bar graph and table comparing the most recent levels of VOCs exceeding the 2L Standard compared to their respective maximum observed levels is presented on Figure 1. A site map depicting the spatial distribution of VOC concentrations exceeding the 2L Standard during this sampling event is shown in Sheet 2. Surface Water Samples Detected Above Standards Attached Table 6 summarizes constituents that were detected above the MDL compared to compliance values listed in the current version of the Division of Water Quality Surface Water Quality Tables. SW- 4R contained cadmium (2.2 ug/L) and copper (5.8 ug/L) which are above their respective 2B Standard (1.23 ug/L and 5.67 ug/L). SW-6 also contained cadmium at 1.3 ug/L which is above its calculated 2B Standard 0.67 ug/L. Groundwater and Surface Water Characterization At the landfill, groundwater flow direction generally mirrors topography, thus flow direction is from higher to lower elevations as shown on the potentiometric map included as Sheet 2. Locally, groundwater flow is expected to be generally westerly toward the Lower Little River, and southerly toward the Catawba River. Groundwater linear velocity rates calculated using modified Darcy's equation varied greatly and were slower in the upper bedrock fracture system than the less prominent regolith (Table 7). Streams at designated monitoring points were visually observed to be of normal seasonal volume, flow rate and low turbidity. Hydrogeologic parameters appear generally consistent with historical observations. Corrective Action Update Groundwater remediation continues to be implemented at the four AOCs designated in the CAP -Add. General background information and activities performed since the CAER and last semi-annual event are briefly presented in the following sections. MNA Analysis (ADCs MW-16, MW-24, MW-26) Semi-annual MNA monitoring of 14 wells for the full suite of SWS recommended parameters was initiated on June 30, 2009 and performed during four consecutive semi-annual events to establish a baseline per the CAP -Revision 1. The number of wells requiring MNA analysis was reduced to 10. The parameters and frequency were also amended per the SWS CAER review response (DIN 14150) dated June 16, 2011. MNA data collected during this event is presented on Table 5. Following an acquisition of a 15.7 acre parcel from Crescent Resources on March 3, 2011, extension of the eastern relative point of compliance downgradient of AOC MW-16 has been approved with conditions by the SWS on February 18, 2013 (DIN:18502). Recordation of Survey Plat titled Survey for Notice of Contaminated Site Alexander County Landfill and A Notice and SWS approved Declaration of Perpetual Land Use Restrictions for this parcel has remained at the Alexander County Register of Deeds Office 4 since November 13, 2012. Alexander County purchased another 2.15 acre parcel that adjoins the NE corner with deed recorded on 3/26/18 which effectively increases the relevant compliance boundary in a NE direction. The SWS approved CAP -Add and CAER (2017) clarifies that groundwater remediation of AOC MW-16 will remain as MNA, rather than other technologies described in the preceding CAP -Add. Phytoremediation (AOC MW-24) County personnel planted approximately 200 hybrid poplar trees over an approximate one acre area between MW-7 and MW-12 in May 2010 in an effort to phytoremediate groundwater in the MW-24 AOC. The County continued to maintain the fence -enclosed stand during this semi-annual period which included supplemental watering and eradication of competing vegetation. Total cumulative VOC concentrations in AOC MW-24 during this event have decreased 61% compared to its respective 2 year baseline established in 2010 and a statistical decreasing trend is evident. Assessment of the phytoremediation area which includes tree measurements and downloading groundwater fluctuation from dedicated transducers was performed by MESCO personnel on July 16, 2020. The majority of the trees appear to be dying or have died; therefore, Alexander County should consider replanting some trees. Enhanced Bioremediation via Substrate Injection (AOC MW-26) In an attempt to remediate benzene as detected in MW-26, Bac-9 was injected 50 ft upgradient in IW-1 on February 17, 2011 following conditions in the Underground Injection Control (UIC) Permit WI0300160. The UIC permit was recently renewed and as directed by the UIC post -injection water quality monitoring of MW-3, MW-11, MW-26, MW-27 and MW-31 is required on a semi-annual basis. Benzene has fallen below slightly below the 2L Standard during this event. Contaminants remain within allowable levels at MW-31 located along the MW-26 flow path beyond the compliance boundary. Most recent levels of total VOCs compared to the baseline established during the four events prior to injection exhibited a reduction both upgradient (-53%) and downgradient (-89%) of the injection point. Most recently, total cumulative VOCs from all samples in AOC MW-26 decreased 62% and benzene concentrations fell 43% compared to the baseline averages established during the four events performed over the two years preceding the injection (Figure 2). Further injections are not planned at this time. Landfill Gas Extraction (AOC MW-M) Three LFG extraction wells (MEW-1, MEW-2, MEW-3) were installed screening the majority of the vadose zone at the northern border of the closed landfill in the vicinity of the scalehouse. MEW-1 was installed on August 17, 2010 with MEW-2 and MEW-3 installed on October 20, 2010. Well control heads were plumbed to a header pipe by the County which was connected to a soil vacuum extraction (SVE) unit on July 5, 2012. An active LFG blower system pilot study was performed by MESCO between June 14, 2012 and July 12, 2012 to evaluate the effectiveness a vacuum would have on reducing levels of LFG in the soil which may remediate the low-level VOCs detected in groundwater hydraulically upgradient of the landfill. A comparison of LFG concentrations and pressures before and after vacuum start-up indicated the system is capable of eliminating LFG migration at all locations monitored within AOC MW-1B. The active LFG Collection Control System (LFGCCS) has been in continuous operation since November 1, 2012 and been verified and documented by MESCO personnel on at least a quarterly basis to be mitigating LFG migration through the vadose at all locations monitored beyond the extraction wells. Improvement in groundwater quality has also been observed in response to implementation of the LFG extraction system as summarized below and shown on Figure 3. 5 Decreased Contaminants Since LFG Extraction Began We11ID Dissolved Methane(%) Benzene (%) Total VOCs (%) MW-1 -92 -86 -84 MW-1B -99 -97 -97 The LFGCCS is planned to remain in operation and will continue to be monitored and assessed on a quarterly basis. Findings During this event there were 24 instances of metals detected in quantifiable concentrations above NC 2L/lMAC values which is typical for this site. Cobalt continues to be the most prevalent metal detected and was found in 46% of the samples. The source of metals is believed to be a product of erosion of natural deposits except for mercury which is believed to be transported via LFG. The semi-annual laboratory results indicate that dissolved phase VOCs, consisting primarily of benzene and a few chlorinated solvents, continue to be detected in groundwater samples collected within 270 feet of the waste boundary. All VOCs detected during this event remain within their own respective historically identified range. Total VOC concentrations have not exhibit an increasing trend over time site -wide and in each of the AOCs. Statistical Mann Kendall trend analysis performed at both a 90% and 95% confidence interval indicates a downward trend of total cumulative VOC concentrations at every AOC (Appendix Q. Total VOC concentrations during this event, compared to their own respective averages calculated during the two year baseline period (ended in 2010), indicate a reduction in each of the AOC's as shown on Figure 4 and summarized below. Total Cumulative VOCs Baseline Average Compared to July 2020 AOC 11 Total VOCs Baseline (ug/L) Total VOCs July 2020 ff (ug/L) Reduction (%) Statistical Trend AOC MW-1B 12.16 0.94 -92 11 Downward AOC MW-16 12.14 11 6.49 -47 Downward AOC MW-24 7.92 3.08 -61 Downward AOC MW-26 30.24 12.30 -59 Downward AOC Undesignated 12.39 6.18 -50 Downward All Wells 14.58 6.05 -58 Downward 2 Evaluation of current water quality data continues to support assertions drawn in previous reports. VOCs persist in the upper portion of the aquifer but concentrations continue to decrease over time and distance away from the landfill. MNA data and previous screening models indicate that the plumes within each AOC are stabilizing and/or decreasing and there is evidence that natural attenuation is ongoing at the facility. Implementation of the corrective action measures coupled with natural attenuation is expected to decrease VOC concentrations in groundwater over time. Closing Water quality monitoring and corrective action is planned to continue in December 2020. Notwithstanding any changes targeting of the full Appendix II list of constituents is planned to occur again during the Spring of 2022. 7 Sheets Topographic Map with Site Location Alexander County Active C&D and Closed MSWLF 'rv��o ar.7e oevewr.r�f o�� -xe irvreRiov 2500 Paynes Dairy Road Taylorsville, NC 28681 Lat:35-15-18.7246 Long:-81-08-51.51.32 Northing:767009.09 Easting:1363506.43 tN rLANDFILL PROPERTY QUADRANGLELEGEND ROAD CLASSIFICATION Primary highway, Light -duty road, hard or hard surface .............. improved surface .... ___ Secondary highway, hard surface ............
