(CDM Smith), on behalf of Cabarrus County, is submitting an electronic copy of the November 2021 semi-annual sampling event report. This letter report presents the results of the recently completed sampling at Units 2 and 3 of the Cabarrus County Landfill and constitutes the second semi-annual sampling event for 2021. The approved groundwater monitoring network consists of the following wells: MW-1, -3, -3 Deep, -A, -B, -C, -D, -E Rep, -E Deep, -F, -G, -H, -H Deep, -I, -J, -K, -L, -L Deep, -M, -X, CD-4 Rep, assessment wells AMW-1s, -1d, -2s, and -2d, and background wells CD -Is and CD-1d. Surface water sample locations include SW-1 and -2, which also monitor the Unit 1 Landfill. Assessment wells AMW-1s, -1d, -2s, and -2d were added to the groundwater monitoring network in October 2009 as part of the Corrective Action Plan (CAP) implementation. CD-4 Rep was installed in January 2009 as part of the proposed Phase I C&D Landfill expansion. Assessment wells CD-4, -5, and -6 were added to the groundwater monitoring network in September 2006 during the Phase I C&D Landfill expansion. Assessment wells CD-4 and -5 were abandoned in July 2010 in preparation of the Phase 2 C&D Landfill expansion. Assessment well CD-6 was abandoned on February 2, 2017, as part of the Phase 3 C&D Landfill expansion. Field activities, sampling and landfill gas screening results, and an evaluation of corrective action activities are discussed below. Field Activities Groundwater samples from Units 2 and 3 of the Cabarrus County Landfill were collected on November 15-19, 2021, except for monitoring wells MW-3 Deep, -L Deep, and -M, which are sampled annually in the spring. Surface water sample locations SW-1 and -2 were dry during the November 2021 sampling event. Groundwater samples were collected from the monitoring wells by use of disposable, laboratory Of WATER + ENVIRONMENT +TRANSPORTATION + ENERGY + FACILITIES Smith Ms. Jaclynne Drummond January 19, 2022 Page 2 decontaminated TeflonTm bailers. Monitoring well and surface water locations for Units 2 and 3 are provided on Figure 1. Construction details for each monitoring well are summarized in Table 1. Groundwater elevations were measured at each well on November 15, 2021, prior to sampling and are presented in Table 2. These groundwater elevations were used to construct potentiometric contours for this sampling event and are presented on Figure 1. The groundwater elevations and potentiometric contours were used to estimate groundwater velocities at each well, which are presented in Table 3. After depth to groundwater was measured, three well volumes of water were removed from each well prior to sampling to provide fresh formation water within the well water column. Low -flow sampling techniques were used to purge and sample wells used to monitor natural attenuation. Each well volume was measured for pH, conductivity, turbidity, temperature, dissolved oxygen (DO), and oxidation- reduction potential (ORP) using a YSI-556 multi -parameter water quality meter and a HANNA HI 98703 turbidity meter. Wells with elevated turbidity were allowed to settle prior to sampling. The water quality parameters at the time of sampling are presented in Table 4. Sampling Results Pace Analytical Services, Inc., located in West Columbia, South Carolina, analyzed the groundwater and surface water samples for North Carolina Appendix I volatile organic compounds (VOCs) and metals. In a letter dated May 28, 2019, the Solid Waste Section (SWS) requested that all groundwater and surface water samples collected from landfills be analyzed for 1,4-dioxane after July 1, 2018. On July 1, 2019, the SWS approved the removal of 1,4-dioxane from the sampling program for all wells, with the exceptions of MW-1, -B, -E Rep, -E Deep, -F, -G, -H, -M, -X, SW-1 and -2, due to two consecutive non - detect events (May 2019 and November 2019). Samples were collected from the wells requiring the 1,4-dioxane analysis during the November 2021 sampling event. Samples results are provided below. Additional groundwater samples were collected from the background well CD-1s; monitoring wells MW-A, -E Rep, -E Deep, -L, and -3; and assessment wells AMW-1s, -1d, -2s, and -2d to evaluate the effectiveness of natural attenuation and the Phase II injection event and are discussed in the Corrective Action Evaluation section of this letter report. Samples were analyzed for monitored natural attenuation parameters (i.e., alkalinity, biochemical oxygen demand, chemical oxygen demand (COD), chloride, dissolved hydrogen, dissolved gases (i.e., methane, ethane, ethene, carbon dioxide), volatile fatty acids (i.e., acetic, butyric, lactic, propionic, and pyruvic), ferrous iron, nitrate, sulfate, sulfide, and total organic carbon). Note that ferrous iron was analyzed in the field using a Hach® test kit due to the short hold time of 15 minutes. The analytical results were reported to the laboratory specific method detection limit (MDL) and are quantifiable at or below the method reporting limit (MRL). All monitoring wells for Units 2 and 3 with detections of analytes above the MDL but below the MRL were qualified as estimated or "J" flags. In samples collected from MW-A, a detection of methane had an "H" flag, indicating that the analyte was analyzed outside of hold time. In MW-C, -D, -E Rep, -E Deep, and -G, detections of chloroethane also had 0 Smith Ms. Jaclynne Drummond January 19, 2022 Page 3 "H" flags. Detections of methane had "D" flags in samples collected from MW-A and -E Deep, indicating that the analyte was analyzed at a dilution greater than one. In MW-E Rep, -E Deep, and -G, detections of barium also had "D" flags. Additionally, in MW-E Deep, detections of chloride and nitrate also had "D" flags. In samples collected from MW-1, -X, and CD-4 Rep, detections of copper had "B" flags, indicating that the analyte was detected in the method blank. The following list indicates the analytes detected above the MRL at each sampling location. No "J" flag or general chemistry detections are provided. Underlined analytes exceeded the 15A NCAC 02L .0202 (NC 2L) Groundwater Standard or Interim Maximum Allowable Concentration (IMAC). A complete summary of all detected and estimated concentrations from the May 2011 through the November 2021 sampling events is presented in Table 5.

An estimated detection of chromium and a detection of copper with a "B" flag were detected in the equipment blank below their respective NC 2L Groundwater Standards. The duplicate sample, identified as Dup, was collected from MW-H Deep, and had similar analyte concentrations as those detected in MW-H Deep, except for an estimated detection of nickel in the parent sample below its NC 2L Groundwater Standard. Metals detected above the standards are likely natural occurring based on concentrations in the background monitoring wells or are from elevated turbidity at the time of sample collection. Table 6 0 Smith Ms. Jaclynne Drummond January 19, 2022 Page 7 presents a summary of all analytes detected during the November 2021 sampling event that exceeded the NC 2L Groundwater Standards or IMACs. Corrective Action Evaluation In December 2008, CDM Smith, on behalf of the County, submitted an Assessment of Corrective Measures Report to the SWS for the closed landfill Units 2 and 3 in accordance with North Carolina Solid Waste Management Rule 15 NCAC 13B .1635. Monitored natural attenuation and institutional controls paired with in situ remediation by enhanced bioremediation was selected as the remedy to address groundwater contamination by select VOCs at the facility. In situ remediation efforts were to be focused on the bedrock contamination near monitoring wells MW-E Rep and -E Deep. Groundwater contamination in the area of MW-E Deep is caused by migration of leachate from the closed landfill Units 2 and 3 downward into the shallow fractured bedrock, thereby allowing low-level VOCs to migrate into this area prior to being attenuated below NC 2L Groundwater Standards. Following approval of the CAP in September 2009 and the Phase I injection permit, six injection wells were installed upgradient of the MW-E cluster in October 2009 as shown on Figure 2. A 3% solution of potable water and EOS® 450, which is an emulsion of soybean oil and water, was injected simultaneously into the injection wells from November 2-6, 2009. A total of 38,100 gallons of the solution were injected with each well receiving approximately 6,350 gallons. The initial injection of EOS®450 successfully degraded PCE and TCE to daughter products in the injection area and neither compound has been detected above the NC 2L Groundwater Standards in MW-E Deep since the Phase I injection in November 2009. It was assumed that the EOS® 450 would be viable for a period of 3 to 5 years. However, samples collected from the MW-E cluster and wells downgradient of the injection area during the November 2013 sampling event showed that groundwater contaminant concentrations had increased and levels exceeding the applicable NC 2L Groundwater Standards had been detected in monitoring wells near the property line. Due to the increasing downgradient contaminant concentrations and NC 2L Groundwater Standard exceedances near the property line, the groundwater conditions were re-evaluated in accordance with the CAP and a Phase 11 injection was implemented. In order to assess the biological conditions in the injection area prior to initiating the Phase II injection, groundwater samples were collected from MW-E Rep, -E Deep, AMW-1s, -1d, -2s, and -2d in January 2014 and analyzed for Deholococcoides spp (DHC), the bacteria responsible for degrading the chlorinated ethene species of VOCs. The specific genes of the bacteria that promote dechlorination were also analyzed. Analytical results for the DHC analyses are summarized in Table 7 and show that a sufficient population exists at monitoring wells MW-E, -E Deep, and assessment monitoring well AMW-2s for reductive dechlorination by enhanced anaerobic bioremediation. DHC was detected at low concentrations in assessment monitoring wells AMW-1d and -2d and was not detected at AMW-1s. The absence of DHC at AMW-1s is likely associated with relatively low VOC concentrations. 0 Smith Ms. Jaclynne Drummond January 19, 2022 Page 8 Following approval of the injection permit in January 2014, the Phase II injection was completed from February 10-18, 2014, using potable water and a 10% solution of 60% SRS®-FR large droplet emulsified vegetable oil substrate. SRS®-FR is specifically designed for use in fractured bedrock environments and is a mixture of 60% emulsified vegetable oil, 20% water, 5-15% of proprietary emulsifiers and nutrients, and 5% sodium lactate. The nutrient component of SRS®-FR further enhances the microbial population growth. A total of 9,966 gallons of the solution were injected during the Phase II event with each well receiving approximately 1,661 gallons. To monitor the progress of the Phase II injection and the geochemical and biological response of the aquifer, groundwater samples were collected quarterly from monitoring wells MW-E Rep and -E Deep and assessment wells AMW-1s, -1d, -2s, and -2d. The first and third quarterly sampling events were completed in conjunction with the May and November 2014 semi-annual sampling events respectively. The second quarterly sampling event was completed in August 2014 and the fourth quarterly sampling event was completed in March 2015. A 15-month post -injection sampling event was completed in May 2015. Water quality measurements of pH, temperature, ORP, DO, conductivity, turbidity, and ferrous iron were collected during each sampling event. In addition, the quarterly samples were submitted to an analytical laboratory for analysis of nitrate, sulfate, alkalinity, chloride, COD, VOCs, dissolved gasses, and metabolic acids. North Carolina Appendix I metals were collected during events that corresponded with the semi-annual sampling program. Additional samples were collected during the fourth quarterly sampling event (March 2015) from monitoring wells MW-E Rep and -E Deep and assessment wells AMW-1s, -1d, -2s, and -2d and analyzed for DHC to assess the biological conditions in the injection area after initiating the Phase II injection. A sufficient population of DHC existed at assessment monitoring well AMW-1d for reductive dechlorination by enhanced anaerobic bioremediation and DHC was detected at low concentrations in monitoring well MW-E Deep. Detections of DHC in AMW-1d indicated a healthy population of DHC in the primary bedrock treatment zone surrounding the injection wells. DHC detections in MW-E Deep was an indication that active treatment in bedrock was also occurring downgradient. DHC was not detected at MW-E Rep, AMW-1s, -2s, or -2d and was likely due to reduced VOC concentrations from upgradient treatment. Analytical results for the DHC analyses are summarized in Table 7. On September 28, 2015, a report summarizing the results of the Phase II injection was submitted to the SWS. The report stated that the Phase II injection of emulsified vegetable oil replenished the carbon source and complete reductive dechlorination is occurring at MW-E, -E Deep, and AMW-1d. The presence of DHC populations and functional genes in MW-E Deep and AMW-1d demonstrate that the treatment process can achieve complete chlorinated VOC degradation as long as a sufficient carbon donor is present. 0 Smith Ms. Jaclynne Drummond January 19, 2022 Page 9 As part of the semi-annual monitoring program, additional groundwater samples were collected from the background well CD-1s; monitoring wells MW-A, -E Rep, -E Deep, -L, and -3; and assessment wells AMW-1s, -1d, -2s, and -2d. Samples were analyzed for monitored natural attenuation parameters. These additional samples were collected to evaluate natural attenuation and the effectiveness of the Phase II injection as part of the CAP. A complete summary of the geochemical results is provided in Table 5. Contaminant concentration trends for MW-A, -3, -E Rep, -E Deep, AMW-1s, -1d, -2s, and -2d were evaluated to determine the effectiveness of natural attenuation and the Phase II injection. Figures 3 through 10 present total VOC contaminant concentration data for each well. An isoconcentration contour map with data from the November 2021 sampling event is provided on Figure 11. The total VOC trend analysis for MW-A is presented on Figure 3. Total VOC concentrations increased in MW-A between June 1995 and April 2003 and show a decreasing trend from April 2003 to November 2021. Figure 4 presents the total VOC trend analysis for MW-3. Total VOC concentrations show an increasing trend. 1,1-Dichloroethane, PCE, and TCE are the only analytes that have been detected in MW-3 above the NC 2L Groundwater Standards. The geochemical data indicates aerobic conditions at MW-3. VOC concentrations in MW-3 Deep have never been detected above the standards. The total VOC trend analyses for MW-E Rep and -E Deep are presented on Figures 5 and 6, respectively. Total VOC concentrations in MW-E Rep and -E Deep have decreased since the November 2009 Phase I injection. PCE and TCE have not been detected above the NC 2L Groundwater Standards in MW-E Deep since the Phase I injection and have not been detected above the MDL since August 2010. Delivery of the carbon substrate (i.e., SRS®-FR) during the Phase II injection was effective based on the increase in COD at MW-E Deep. Historical geochemical data shows reducing conditions exist at the MW-E cluster based on low DO and high methane concentrations. ORP has fluctuated since the November 2016 sampling event. The increase in metabolic acids and ferrous iron at MW-E Deep also indicates that a reducing subsurface environment exists. A geochemically reducing environment is favorable for anaerobic reductive dechlorination. Figures 7 and 8 present the total VOC trend analyses for assessment wells AMW-1s and -1d, respectively. Total VOC concentrations in AMW-1s show an increasing trend from November 2010 to May 2013 but show a decreasing trend from May 2013 to November 2021. VOCs have not been detected above the MDL in AMW-1s since the September 2020 sampling event. Total VOC concentrations in AMW-1d show a decreasing trend from the initial sampling in October 2009 to November 2019 but have fluctuated since the November 2019 sampling event. Historical data shows reducing conditions existed at AMW-1d but DO and ORP have fluctuated since the November 2017 sampling event. The concentration of vinyl chloride generally increased from the Phase II injection to November 2017 while TCE concentrations decreased, indicating anaerobic reductive dechlorination is 0 Smith Ms. Jaclynne Drummond January 19, 2022 Page 10 occurring as vinyl chloride is a daughter product of TCE. However, from November 2017 to September 2020, TCE concentrations increased, and the concentration of vinyl chloride decreased. The results of the March and November 2021 sampling event show that TCE was not detected above the standard and the concentration of vinyl chloride increased. The total VOC trend analyses for AMW-2s and -2d are presented on Figures 9 and 10, respectively. Total VOC concentrations at AMW-2s show an increasing trend between the initial sampling event in October 2009 and November 2014 and have fluctuated since the November 2014 sampling event, but generally show a decreasing trend. Total VOC concentrations show an increasing trend at AMW-2d from November 2010 to November 2017 but have fluctuated since then. The AMW-2 cluster is located farthest downgradient of the injection area and the shallow well is screened in partially weathered rock. Geochemical results indicate an aerobic subsurface environment. Landfill Gas Monitoring The approved landfill gas monitoring network consists of monitoring wells MGW-1 through -16. Site structures that are monitored on the property include the scale house, maintenance shop, electricity building, and recycling facility. Quarterly landfill gas monitoring of the facility was completed on September 13 and November 30, 2021, using a GEM 5000+ landfill gas analyzer. No methane or hydrogen sulfide was detected in any monitoring wells or site structures during either monitoring event. Copies of the quarterly landfill gas monitoring results and equipment calibration data have been placed in the landfill operating record and are provided in Appendix B. Recommendations Units 2 and 3 of the Cabarrus County Landfill are unlined and are the source of VOC concentrations that are above the NC 2L Groundwater Standards or IMACs in downgradient monitoring wells. The injection remedy successfully reduced the contaminant concentrations in bedrock monitoring well MW-E Deep and developed a primary VOC treatment zone in the vicinity of the injection wells and MW-E Rep. Downgradient VOC concentrations in bedrock and saprolite should continue to decrease due to reduced VOC concentrations in the primary treatment zone. Additional injections will be necessary in the future once all electron donors have been consumed and complete dechlorination stalls. The County will continue with the semi-annual assessment monitoring program. In addition to sampling for Appendix I VOCs, including 1,4-dioxane, and metals, and the Appendix II constituent, bis(2-ethylhexyl) phthalate (sampled at CD-1s, -1d, MW-C, -E Deep, -H, -I, and AMW-2d during the spring sampling event), samples collected from CD-1s, MW-A, -E Rep, -E Deep, -L, -3, AMW-1s, -1d, -2s, and -2d will continue to be analyzed for natural attenuation parameters during the semi-annual sampling events. Future analytical results will be monitored to evaluate if another injection will be needed. The next sampling event will be completed in the spring of 2022. 0 Smith Ms. Jaclynne Drummond January 19, 2022 Page 11 If you have any questions or require further explanation, do not hesitate to call me at (919) 325-3500 or by email at colonemf@cdmsmith.com.

Only Chloroethane has been reported from Run 2. All other sample results are as reported in the original PDF report. This report supersedes and replaces any prior reports issued under this lot number. This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary following this Case Narrative. The sample receiving date is documented in the header information associated with each sample. All results listed in this report relate only to the samples that are contained within this report. Sample receipt, sample analysis, and data review have been performed in accordance with the most current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace") Laboratory Quality Manual, standard operating procedures (SOPS), and Pace policies. Any exceptions to the TNI standards, the Laboratory Quality Manual, SOPS or policies are qualified on the results page or discussed below. Pace is a TNI accredited laboratory; however, the following analyses are currently not listed on our TNI scope of accreditation: Biological Tissue: All, Non -Potable Water: SGT-HEM EPA 1664B, Silica EPA 200.7, Boron, Calcium, Silicon, Strontium EPA 200.8, Bicarbonate, Carbonate, and Hydroxide Alkalinity SM 2320 B-2011, Fecal Coliform SM 9221 C E-2006 & SM 9222D-2006, Strontium SW-846 601 OD, VOC SM 6200 B-2011, Drinking Water: VOC (excluding BTEX, MTBE, Naphthalene, & 1,2-dichloroethane) EPA 524.2, Solid Chemical Material: TOC Walkley-Black. VOA 8260D Due to the large number of spiked analytes, there is a high probability that one or more analytes will recover outside acceptance limits. The laboratory's SOP allows for 10% of analytes to recover marginally outside criteria. The following analytes recovered marginally outside LCS/LCSD criteria: trans- 1,4-dichloro-2-butene @ 63%. Associated samples: WK17018-010 (MW-E REP), WK17018-011 (MW-E deep) and WK17018-012 (AMW-1s) The laboratory control sample (LCS) for analytical batch 23641 exceeded acceptance criteria for the following analytes: acetone. These analytes were biased high and were not detected in the associated samples: WK17018- 010 (MW-E REP), WK17018-011 (MW-E deep), and WK17018-012 (AMW-1s). The laboratory control sample (LCS) for analytical batch 23569 exceeded acceptance criteria for the following analytes: ,2-Butanone and 2-Hexanone. These analytes were biased high and were not detected in the samples affected: WK17018-015 (MW-H) , WK17018-016 (MW-L), WK17018-017 (MW-3), and WK17018-019 (TRIP BLANK). Trans 1, 4-Dichloro-2-butene failed readback associated with the calibration (ICAL) of the instrument used in this sequence. The compound passes using linear fit but the readback fails extremely high at 343% drift. Since the compound is detected in the LOQ associated with this sequence and samples are non -detect, the data has been reported for the following samples: WK17018-015 (MW-H) , WK17018-016 (MW-L), WK17018-017 (MW-3), and WK17018-019 (TRIP BLANK). Reanalysis of the following samples was performed outside of the analytical holding time for Chloroethane due to high failure in the CCV: WK17018-010 (MW-E REP) and WK17018-011 (MW-E deep). 1,4-dioxane SIM 8260D The following samples were analyzed using unpreserved sample vials due to analyst error: WK17018-014 (AMW-2s), WK17018-016 (MW-L), and WK17018-017 (MW-3). The unpreserved vials were analyzed within hold time, therefore data will be reported.

Both analytical runs have been reported. Nitrate-N 9056A The following samples were diluted due to the nature of the sample matrix: WK17018-004 (MW-A), WK17018-005 (AMW-2d), and WK17018-010 (MW-E REP). The LOQ has been elevated to reflect the dilution. The reanalysis for samples WK17018-004 (MW-A) and WK17018-010 (MW-E REP) was performed outside of the analytical holding time. These samples were reanalyzed outside holding due to matrix interference during initial analysis. Both sets of data have been reported. The MS/MSD for batch 22958 and parent sample WK17018-004 (MW-A), recovered outside the lower control limit. The associated LCS passed acceptance criteria. COD The MSD for batch 23842 and parent sample WK17018-005 (AMW-2d), recovered marginally outside the lower control limit. The associated LCS and MS passed acceptance criteria. BOD The seed correction factor for samples WK17018-004 (MW-A) and WK17018-005 (AMW-2d) was above the method range of 0.6 to 1.0. SCF = 1.1 The seed correction factor for the samples listed below was above the method range of 0.6 to 1.0. SCF = 1.6 WK17018-010 (MW-E REP) WK17018-011 (MW-E deep) WK17018-012 (AMW-1s) WK17018-013 (AMW-1d) WK17018-014 (AMW-2s) WK17018-016 (MW-L) WK17018-017 (MW-3) The results of the three GGA check samples associated with the batch are as follows: 157.6 mg/L, 168.6 mg/L, and 173.6 mg/L. The resulting average BOD for the three bottles, after correcting for dilution and seed is 166.6 mg/L which is lower than the method required range of 198±30.5 mg/L. The data for the associated samples (WK17018- 004 (MW-A) and WK17018-005 (AMW-2d)) has been flagged accordingly. Alkalinity Analytical batch 23834 does not have duplicate reported. A duplicate was analyzed during the analysis; however, due to instrument error, a majority of the samples did not have reportable data. The sample (WK17018-005 (AMW- 2d) that was analyzed in duplicate was one of the samples affected. Results have been uploaded for the reportable samples in the batch.

Only Chloroethane has been reported from Run 2. All other sample results are as reported in the original PDF report. This report supersedes and replaces any prior reports issued under this lot number. This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary following this Case Narrative. The sample receiving date is documented in the header information associated with each sample. All results listed in this report relate only to the samples that are contained within this report Sample receipt, sample analysis, and data review have been performed in accordance with the most current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace") Laboratory Quality Manual, standard operating procedures (SOPS), and Pace policies. Any exceptions to the TNI standards, the Laboratory Quality Manual, SOPS or policies are qualified on the results page or discussed below. Pace is a TNI accredited laboratory; however, the following analyses are currently not listed on our TNI scope of accreditation: Biological Tissue: All, Non -Potable Water: SGT-HEM EPA 1664B, Silica EPA 200.7, Boron, Calcium, Silicon, Strontium EPA 200.8, Bicarbonate, Carbonate, and Hydroxide Alkalinity SM 2320 B-2011, Fecal Coliform SM 9221 C E-2006 & SM 9222D-2006, Strontium SW-846 6010D, VOC SM 6200 B-2011, Drinking Water: VOC (excluding BTEX, MTBE, Naphthalene, & 1,2-dichloroethane) EPA 524.2, Solid Chemical Material: TOC Walkley-Black. VOA 8260D The laboratory control sample (LCS) for analytical batch 23569 exceeded acceptance criteria for the following analytes: Acetone 2-Butanone and 2-Hexanone. These analytes were biased high and were not detected in the associated sample: WK19034-011 (CD4 Rep). Trans 1, 4-Dichloro-2-butene fails read back associated with the calibration (ICAL) of the instrument used in this sequence. The compound passes using linear fit, but the read back fails extremely high at 343% drift. Since the compound is detected in the LOQ associated with this sequence and samples are non - detect for analyte, the data has been reported for the following sample: WK19034-011 (CD4 Rep) The laboratory control sample (LCS) for analytical batch 23728 exceeded acceptance criteria for the following analytes: Acetone and acrylonitrile. These analytes were biased high and were not detected in the associated samples: WK19034-001 (MW-1), WK19034-002 (MW-G), WK19034-003 (MW-B), WK19034-004 (MW-F) , WK19034-005 (MW-D), WK19034-006 (MW-K), WK19034-007 (MW-C), WK19034-008 (MW-J), WK19034-009 (MW-X), and WK19034-010 (EQ-BLANK-2).

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.
