Box 349, BOONE, NC 25607 -PHONE: 828-262-1767 LICENSE NUMBERS: F-OB12 & C•SBfi Introduction On behalf of Alexander County, Municipal Engineering, Inc. (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 December 14-16, 2021. NCDEQ 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 three constituents above regulatory compliance Standards. Metal detections are generally believed to originate from erosion of natural deposits. The source of VOCs is likely anthropogenic. Cobalt may have been detected above its allowable surface water compliance value in samples collected from two downstream surface water points. 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 generally 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-lA and MW-2 which were dry. Monitoring locations are depicted on the potentiometric surface map (Sheet 2). Sampling was performed per the protocols outlined in the WQMP. A summary detailing the construction of the water quality monitoring wells is presented in Table 1. The function and integrity of all monitoring locations were visually evaluated and maintenance performed as documented in 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 stabilized 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, oxidation reduction potential (ORP), dissolved oxygen (DO), 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 constituents, mercury and MNA performance parameters as prescribed in the approved WQMP. A few MNA parameters, that are on an annual frequency, were inadvertently not tested during this event but will be during the next event. 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 Arsenic was detected below quantification levels in the EB sample. Arsenic was not detected above the MDL in any other sample; therefore, the presence of the artifact contaminant is 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 RL and respective NC 2L Standard/IMAC Value in samples collected from 18 wells, including the background well, as summarized below. Metals Detected in Groundwater Samples Above RL and NC 2L Standard/IMAC Values Chromium Cobalt Mercury Vanadium 2L/IMAC 10 1 1 0.3 MW-18 (BG Well) 6.3 1.9 7.1 MW-1 10 MW-lB 58.2 3.1 MW-3 13.6 MW-4R 143 MW-5 10.3 MW-6 66.5 MW-9 396 MW-11 106 MW-12 111 MW-14 139 MW-15 29.8 MW-16 362 MW-17 11 48.6 18.8 MW-23 95.6 MW-24 22.3 MW-26 94.5 MW-33 124.2 Concentrations in ug/L 3 VOCs Benzene was detected above the RL and 2L Standard (1.0 ug/L) in samples collected from MW-3 (4.4), MW-4R (1.3), MW-5 (2.8), MW-7 (2.4), MW-11 (3), MW-12 (1.9), MW-15 (2.3), MW-16 (1.6) and MW-26 (2.4). 1,4-dichlorobenzene was found in sample MW-3(8.6), MW-11 (8.8) and MW-12 (7.3) which is above the NC 2L Standard (6 ug/L). Vinyl chloride was detected in sample MW-7 at an unprecedented level of 3 ug/L which exceeds its NC 2L Standard (0.03 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 Table 6 summarizes constituents that were detected above the MDL compared to compliance values listed in the current version of the NC Division of Water Resources Surface Water Quality Standards, Criteria & In -Stream Target Values tables dated July 26, 2021. Lab analysis was performed for total recoverable metals on a single grab sample rather than the dissolved fraction, which requires an average of two samples (acute) or four samples (chronic) to be collected during a defined period of time for specific parameters. Several of the NC surface water compliance standards are predicated upon a dissolved standard. Total cobalt was detected in in grab sample SW-5 at 23.8 ug/L which is above the dissolved Standard for chronic (1.6 ug/L) and acute (16 ug/L) impacts. However, because the sample collection and analysis methods were for the total fraction of cobalt as required by the SWS, a direct comparison to the dissolved 2B Standards for surface waters is not appropriate. Groundwater and Surface Water Characterization 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 west toward the Lower Little River, and south 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 moderate 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 in accordance with the CAP -Revision 1. The number of wells requiring MNA analysis was reduced to 10 wells. The parameters and frequency were also amended in accordance with the SWS 4 CAER review response (DIN 14150) dated June 16, 2011. A large number of MNA parameters were targeted during this event and detections are 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 had 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 since November 13, 2012. Alexander County purchased another 2.15-acre parcel that adjoins the NE corner with deed recorded on March 26, 2018, 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 and willow 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 57% compared to its respective 2-year baseline established in 2010 and a statistically decreasing trend is evident. Assessment of the phytoremediation area, which includes tree measurements and the downloading of groundwater fluctuation data from dedicated transducers was performed by MESCO. The majority of the trees appear to be dying or have died. Alexander County has recently received additional hybrid willow trees and plans to replant this Spring. Enhanced Bioremediation via Substrate Injection (AOC MW-26) hi 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 W10300160. The UIC permit was renewed and as directed by the UIC permit, post -injection water quality monitoring of MW-3, MW-11, MW-26, MW-27 and MW-31 is required on a semi-annual basis. VOCs remain within allowable levels in MW-26 and MW-31 located downgradient of the injection point. Most recent concentrations of total VOCs have decreased 14% and benzene has increased 26% downgradient of the injection point compared to the baseline established during the four events prior to injection (Figure 2). Additional injections are not planned at this time. Landfill Gas Extraction (AOC MW-1B) 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 scale house. 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 5 start-up indicated the system is capable of eliminating LFG migration at all locations monitored within AOC MW-lB. 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. Great improvement in groundwater quality has been observed in response to implementation of the LFG extraction system as demonstrated by a reduction of 92% of benzene and 97% of total VOCs as shown on Figure 3. 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/IMAC values which is typical for this site. Cobalt continues to be the most prevalent metal detected and was found in 57% of the samples. All metal concentrations were found within their historically identified range except for mercury in background sample MW-18. The source of mercury as observed in samples MW-1B and MW-18 collected upgradient of the landfill is unknown. The laboratory results indicate that dissolved phase VOCs, consisting primarily of benzene and a few low-level 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 except for vinyl chloride in MW-7. Statistical Mann Kendall trend analysis performed at both a 90% and 95% confidence interval indicate a stable or downward trend of total cumulative VOC concentrations at every well except for MW-5. Total VOC concentrations during this event, compared to their own respective averages calculated during the two-year baseline period (ended in 2010), exhibited a reduction in each of the AOC's as shown on Figure 4 and summarized below. Total Cumulative VOCs Baseline Average Compared to December 2021 AOC Total VOCs Baseline Total VOCs December 2021 Change (%) Statistical Trend Pu g/L) (ug/L) AOC MW-1B 12.16 0.78 -95 Downward AOC MW-16 12.14 12.44 2 Downward AOC MW-24 7.92 4.95 -37 Downward AOC MW-26 30.24 23.33 -23 Downward AOC Undesignated 12.39 11 7.18 -42 Downward All Wells 14.58 9.40 -35 1 Downward 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 2 away from the landfill. MNA data and previous screening models indicate that the plumes within each AOC are stabile 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. It is recommended that surface water samples be tested for dissolved metals if the total form is found elevated compared to dissolved surface water Standards to better determine if surface waters are impaired. Closing Water quality monitoring and corrective action is planned to continue in June 2022. During the next event the full Appendix II list of constituents and MNA performance parameters will be targeted. A CAER, which is required every five years, is planned to be delayed until after the data from the next event is evaluated with a tentative submittal data prior to January 1, 2023. 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 ............

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL -Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean -Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TN -The NELAC Institute.
