This letter report presents the results of the semi-annual sampling event that was recently completed at the Closed Feltonsville Landfill (Site) and constitutes the first semi- annual sampling event for 2024. The current groundwater monitoring network consists of the following wells: MW-2, -4, -6, -8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -18, -19, -20, -21, -22, -23, -24, -25, -26, -27, -28, and -29, and surface water sampling locations SW-1, -2, and -3. Monitoring wells MW-2, -6, -8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -18, -19, -20, -28, and -29 monitor the Site. The remaining wells (i.e., MW-4, -21, -22, -23, -24, -25, -26, and -27) monitor the old cells located in the back of the property. Field activities, sampling results for all wells and surface water locations, an evaluation of the groundwater corrective action effectiveness, and recommendations are discussed below. Field Activities Groundwater samples were collected from the Site on April 22 to 26, 2024, except for surface water sample location SW-2, which was dry. Monitoring well locations are shown on Figure 1 and construction details for each monitoring well are summarized in Table 1. Samples were collected from the monitoring wells by use of a peristaltic pump or disposable, laboratory decontaminated bailer. Groundwater elevations were measured at each well prior to sampling on April 22, 2024, using an electronic water level indicator with an accuracy of 0.01 feet and are presented in Table 1. These groundwater elevations were used to construct potentiometric contours for this sampling event and are shown on Figure 1. The groundwater elevations and potentiometric contours were also used to estimate groundwater velocities at each well as presented in Table 2. After depth to groundwater was determined, a minimum of three well volumes of water were removed from each well prior to sampling to provide fresh formation water within the well water column. Each well volume was measured in the field for pH, conductivity, temperature, turbidity, dissolved oxygen, and oxidation-reduction potential using a YSI-556 multi -parameter water quality meter and a HANNA HI 98703 turbidity meter. Wells that had elevated turbidity (i.e., greater than 10 Nephelometric Turbidity Units (NTUs)) were allowed to stabilize prior to sample collection. The water quality parameters at the time of sampling are provided in Table 3. 5400 Glenwood Avenue, Suite 400 Raleigh, North Carolina 27612 1 tel: 919 325-3500 Smith Ms. Jaclynne Drummond July 23, 2024 Page 2 Alternate Source Demonstration Analytical data was collected from the Site's background monitoring well, MW-2, on a quarterly basis from January 2018 to April 2020 to determine if the metals exceeding the NCAC 02L .0202 (NC 2L) Groundwater Standards or Interim Maximum Allowable Concentrations (IMACs) were due to naturally occurring background concentrations or a release from the landfill. Based on statistical analysis, historical detections of metals above their respective NC 2L Groundwater Standards or IMACs were determined to be indicative of naturally occurring background concentrations instead of a release from the landfill. Future metal detections will be evaluated, and an Alternate Source Demonstration will be submitted to the North Carolina Department of Environmental Quality's Solid Waste Section (SWS) if there are constant detections of metals exceeding their NC 2L Groundwater Standards. Sampling Results Groundwater and surface water samples were analyzed by Pace Analytical Services, LLC, located in Huntersville, North Carolina, for the North Carolina Appendix I volatile organic compounds (VOCs) plus dichlorodifluoromethane and Appendix I metals plus mercury. Additional samples were collected from select monitoring wells to evaluate natural attenuation and the effectiveness of the corrective action. Results of the additional sampling and an evaluation of natural attenuation are discussed in the next section of this report. Groundwater and surface water samples were also analyzed for per- and polyfluorinated substances (PFAS) in accordance with the Solid Waste Section's (SWS) letter dated March 13, 2023. The PFAS laboratory data report is provided in Appendix A. In a letter dated May 29, 2018, the SWS stated that all groundwater and surface water samples collected from landfills be analyzed for 1,4-dioxane after July 1, 2018. On June 26, 2019, the SWS approved the removal of 1,4-dioxane from the sampling program for all monitoring wells and surface water locations, with the exceptions of MW-6, -9, -10, -11, -12, -13, -14, -15, -17, -18, -24, -25, -26, -27, and -29, because of two non -detect events (November 2018 and April 2019). Samples were collected from the monitoring wells requiring the 1,4-dioxane analysis during the April 2024 semi-annual sampling event and analyzed for 1,4-dioxane. Sample results are provided below. The analytical results were reported to the laboratory specific method detection limit (MDL) and are quantifiable at or below the laboratory limit of quantitation (LOQ). The following list indicates the analytes detected above the LOQ at each sampling location. There were no detections in the surface water samples that exceeded the North Carolina 15A NCAC 02B or In -Stream Target Value. Underlined groundwater analytes exceeded the NC 2L Groundwater Standard. A complete summary of all detected and estimated concentrations for the April 2012 through the April 2024 sampling events is provided in Table 4. Laboratory data reports are provided in Appendix A.

A duplicate sample was also collected for quality control. No metals or VOCs was detected in the equipment or trip blanks above the MDLs. The duplicate sample, labeled DUP, was collected from MW-19, and had similar concentrations as MW-19. Table 5 presents a summary of all parameters detected during the April 2024 sampling event that exceeded the NC 2L Groundwater Standards. Pesticides, herbicides, and polychlorinated biphenyls have not been sampled for since April 2011 and the last detections above the standards were in May 2010. Historical data is available upon request. Monitoring Natural Attenuation Sampling Additional groundwater samples were collected from the background well, MW-2, and downgradient monitoring wells MW-8, -9, -10, -12, -13, and -14. The samples were analyzed for alkalinity, biological oxygen demand, chemical oxygen demand (COD), carbon dioxide, chloride, dissolved hydrogen, dissolved gasses (i.e., methane, ethane, ethene), volatile fatty acids (i.e., acetic, butyric, lactic, propionic, and pyruvic), nitrate, sulfate, sulfide, and total organic carbon. Note that samples were not collected for dissolved hydrogen due to field sampler error. Ferrous iron was also analyzed using a HACH test field kit due to the short hold time (i.e., 15 minutes). These additional samples were collected to monitor for natural attenuation as part of the approved corrective action program as required by SWS guidelines. Additional samples were also collected from wells MW-19 and -29, which are located downgradient of the injection area, to monitor the effectiveness of the injection. Samples collected from MW-8, -9, -10, -19, and -29 were also analyzed for TDS. Samples collected from MW-1, -11, -17, -20, and -22 were analyzed for sodium. Sampling results are provided in Table 6 and trend figures of total detected VOCs for select wells are presented on Figures 2 through 10. 5400 Glenwood Avenue, Suite 400 Raleigh, North Carolina 27612 1 tel: 919 325-3500 Smith Ms. Jaclynne Drummond July 23, 2024 Page 6 Corrective Action via In Situ Bioremediation Injection In accordance with the Corrective Action Plan that was approved by the SWS, two in situ bioremediation injections have been completed. Phase I consisted of injecting sodium lactate into five injection wells upgradient of monitoring wells MW-8, -9, and -10. A total of 1,268 gallons of a 10 percent sodium lactate solution were injected resulting in each well receiving approximately 254 gallons of the sodium lactate solution. Phase I post -injection samples were collected 1, 2, and 5 months after injection. During each sampling event, samples from MW-8, -9, -10, -19, and -29 were analyzed for the following field measurements: pH, temperature, oxidation-reduction potential, dissolved oxygen, conductivity, turbidity, nitrate, sulfate, ferrous iron, carbon dioxide, and alkalinity along with laboratory analyses of chlorides, COD, VOCs, dissolved gases, sodium, and TDS. Volatile fatty acids were also collected during the 1-month post -injection sampling event. Additionally, samples were collected from MW-8, -9, and -10 and analyzed for bacterial population size and functional gene presence during the baseline and 5-month post -injection sampling events. Analytical results for the November 2011 through April 2024 sampling events are summarized in Tables 4 and 6. Analytical results post -sodium lactate injection for MW-8, -9, and -10 indicated that bioremediation was occurring with no VOCs detected above NC 2L Groundwater Standards in MW-8 or -10, except for 1,1-dichloroethane detected in samples collected from MW-10 in July 2012. MW-9 had detections of 1,1-dichloroethane, tetrachloroethene, trichloroethene, and vinyl chloride above NC 2L Groundwater Standards, but contaminant concentrations were decreasing. DNA analyses revealed healthy populations of bacteria (Dehalococcoides sp) in MW-9 and -10 that continued to reduce contaminant concentrations. Bacterial populations in MW-8 decreased because of little to no VOCs being detected during the post -injection sampling. The Phase I injection of sodium lactate successfully caused degradation of trichloroethene and tetra chloroethene to daughter products using enhanced anaerobic bioremediation in the injection area. Although the Phase I injection reduced contaminant concentrations, a second injection was needed to supply a longer lasting source of electron donors. Biodegradation can be sustained for as long as sufficient concentrations of substrate remain in the groundwater. For this reason, emulsified vegetable oil was utilized in the Phase 2 injection as it is a slow -release compound, and therefore should release organic carbon into the groundwater for three to five years, depending on site conditions. During the Phase 2 injection, a 10 percent emulsified vegetable oil solution was injected into the injection wells. Injection at each well consisted of approximately 220 gallons of water containing approximately 22 gallons of the emulsified vegetable oil product. The emulsified vegetable oil product consisted of 60 percent emulsified vegetable oil and 4 percent sodium lactate by weight, which resulted in a total injection volume of 1,100 gallons of water and 110 gallons of emulsified vegetable oil product. Post -injection samples were collected 1, 4, 7, 10, and 12 months after injection. The April 2014 monitoring event concluded the post -injection monitoring. Analyses for each sampling event were similar to the Phase I events except that DNA analyses to determine bacterial population size and functional gene presence were only done during the April 2014 sampling event. 5400 Glenwood Avenue, Suite 400 Raleigh, North Carolina 27612 1 tel: 919 325-3500 Smith Ms. Jaclynne Drummond July 23, 2024 Page 7 No VOCs have been detected above the standards in MW-8 since the November 2011 semi-annual sampling event, except for the April 2019 and 2024 sampling events. Samples collected from MW-8 in April 2019 had detections of 1,1-dichloroethane and tetrachloroethene above their respective NC 2L Groundwater Standards. 1,1-Dichloroethane was also detected above the standard during the April 2024 sampling event. In samples collected from MW-9, benzene has been detected above its standard since May 2015, except for the November 2015, April 2016, October 2021, April 2022, and October 2023 sampling events. Benzene was either reported as an estimated concentration below the standard or was not detected from September 1994 to October 2014. 1,1-Dichloroethane has historically been detected above the standard, except during the September 2019, October 2020, September 2022, and October 2023 sampling events. 1,4-Dioxane has been detected at similar concentrations in MW-9 above the NC 2L Groundwater Standard (3 parts per billion (ppb)) since being added to the sampling program in the fall of 2018. Note that 1,4-dioxane was not analyzed in samples collected from MW-9 during the March 2023 sampling event due to laboratory error. Total VOC concentrations have fluctuated since the March 2013 injection. In MW-10, benzene, 1,1-dichloroethane, 1,4-dioxane, and vinyl chloride were detected above their respective NC 2L Groundwater Standard. 1,4-Dioxane has been detected above the standard in MW-10 since being added to the sample program but was not analyzed for the March 2023 sampling event due to laboratory error. The concentration of 1,1-dichloroethane has fluctuated but shows a decreasing trend since the May 2015 sampling event. Concentrations of benzene have historically fluctuated at MW-10 but have shown a decreasing trend since the October 2020 sampling event. As expected, the concentration of vinyl chloride has fluctuated following the Phase 2 injection and has shown a decreasing trend since the May 2015 semi-annual sampling event. No VOCs were detected above the MDLs in samples collected from MW-19 during the April 2024 sampling event. Historically, VOCs have never been detected above the standards in monitoring well M W-19. MW-29, located at the compliance boundary, has not had any chlorinated ethenes detected above the NC 2L Groundwater Standards since November 2012. Chloroethane and 1,1-dichloroethane were detected in samples collected from MW-29 during the April 2024 sampling event below their respective NC 2L Groundwater Standards. 1,4-dioxide was detected above the standard during the April 2024 sampling event. Concentrations of 1,1-dichloroethane have decreased following the injection events. 1,1-Dichloroethane has been detected below the NC 2L Groundwater Standard since the January 2014 post -injection sampling event except for the October 2014 semi-annual sampling event (7.2 ppb) when it was detected slightly above the NC 2L Groundwater Standard (6 ppb). Dechlorination of chlorinated ethenes from tetra chloroethene to ethene is ongoing. The geochemical data will continue to be evaluated to determine if conditions for reductive dechlorination remain present. Subsequent monitoring events will be evaluated to identify any trends. 5400 Glenwood Avenue, Suite 400 Raleigh, North Carolina 27612 1 tel: 919 325-3500 Smith Ms. Jaclynne Drummond July 23, 2024 Page 8 Recommendations Wake County will continue with the semi-annual assessment monitoring program. All wells will continue to be sampled for Appendix I VOCs plus dichlorodifluoromethane and Appendix I metals plus mercury. The concentration of 1,4-dioxane will continue to be monitored in MW-6, -9, -10, -11, -12, -13, -14, -15, -17, -18, -24, -25, -26, -27, and -29. Samples collected from MW-2, -8, -9, -10, -12, -13, -14, -19, and -29 will also be analyzed for natural attenuation parameters.

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. ANALYTE QUALIFIERS v2 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the associated samples and the sensitivity of the instrument was verified with a reporting limit check standard. v3 The continuing calibration verification was below the method acceptance limit.

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. ANALYTE QUALIFIERS 1g Reported from a Sequence that did not include a Closing ISCA/ICSAB. ICSAB immediately before this sample in the sequence meets all method acceptance criteria. B1 Less than 1.0 mg/L DO remained for all dilutions set. The reported value is an estimated greater than value and is calculated for the dilution using the least amount of sample. B2 Oxygen usage is less than 2.0 for all dilutions set. The reported value is an estimated less than value and is calculated for the dilution using the most amount of sample. D3 Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference. M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery. N2 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A complete list of accreditations/certifications is available upon request. P4 Sample field preservation does not meet EPA or method recommendations for this analysis. R1 RPD value was outside control limits. v2 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the associated samples and the sensitivity of the instrument was verified with a reporting limit check standard. v3 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the associated samples may have low bias.

Page 39 of 47 � ace QUALIFIERS Project: Feltonsville Landfill Spring 2 Pace Project No.: 92727093 DEFINITIONS DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot. 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. Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 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. ANALYTE QUALIFIERS B2 Oxygen usage is less than 2.0 for all dilutions set. The reported value is an estimated less than value and is calculated for the dilution using the most amount of sample. D3 Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference. M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery. N2 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A complete list of accreditations/certifications is available upon request. P4 Sample field preservation does not meet EPA or method recommendations for this analysis. v2 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the associated samples and the sensitivity of the instrument was verified with a reporting limit check standard. v3 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the associated samples may have low bias.

Page 43 of 50 � ace QUALIFIERS Project: Feltonsville Landfill Spring 2 Pace Project No.: 92727417 DEFINITIONS DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot. 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. Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 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. ANALYTE QUALIFIERS D3 Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference. L1 Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated samples may be biased high. M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery. N2 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A complete list of accreditations/certifications is available upon request. R1 RPD value was outside control limits. v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the associated samples may have a high bias. v2 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the associated samples and the sensitivity of the instrument was verified with a reporting limit check standard. v3 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the associated samples may have low bias.

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.

Page 39 of 50 � ace QUALIFIERS Project: Feltonsville LF Spring 24 Pace Project No.: 92727736 DEFINITIONS DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot. 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. Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 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. ANALYTE QUALIFIERS B2 Oxygen usage is less than 2.0 for all dilutions set. The reported value is an estimated less than value and is calculated for the dilution using the most amount of sample. D3 Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference. H3 Sample was received or analysis requested beyond the recognized method holding time. IH This analyte exceeded secondary source verification criteria high for the initial calibration. The reported results should be considered an estimated value. L1 Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated samples may be biased high. M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery. N2 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A complete list of accreditations/certifications is available upon request. v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the associated samples may have a high bias. v2 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the associated samples and the sensitivity of the instrument was verified with a reporting limit check standard.

Page 10 of 15 � ace QUALIFIERS Project: Feltonsville LF Spring 24 PFAS Pace Project No.: 92726492 DEFINITIONS DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot. 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. Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 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. ANALYTE QUALIFIERS L2 Analyte recovery in the laboratory control sample (LCS) was below QC limits. Results for this analyte in associated samples may be biased low.

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. Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 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.

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. Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 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.

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. Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 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. ANALYTE QUALIFIERS L1 Analyte recovery in the laboratory control sample (LCS) was above QC limits.

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. Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 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.
