Semi-Annual Water Quality Report – Second Event 2024 December 13, 2024 City of Albemarle Landfill – Albemarle, North Carolina BLE Project No. J24-7013-31 1 of 5 1.0 PROJECT INFORMATION The subject 436.1-acre landfill site is located within the city limits of Albemarle in Stanly County, North Carolina, approximately four miles southeast of the center of the City of Albemarle (Figure 1). The landfill’s physical address is 40592B Stony Gap Rd, Albemarle, North Carolina. The City of Albemarle owns and operates an active Subtitle D MSWLF which includes Phase 1 and Phase 2 and an active CDLF. The active CDLF was constructed over the top of the Unit 1 portion of a closed, pre-subtitle D, MSWLF. The closed MSWLF consists of Unit 1 (closed in October 1991) and Unit 2 (closed prior to June 1999). Both closed MSWLF units were closed by covering with a soil cap. A Water Quality Monitoring Plan (WQMP) dated May 14, 2015 was prepared by Shield Engineering, Inc. (Shield Project 1110192) and submitted to the North Carolina Solid Waste Section (SWS). The WQMP was approved on May 21, 2015 (DIN 24674). BLE submitted (on behalf of the City of Albemarle) the Corrective Action Evaluation Report – Water Quality Data Through July 2021 dated November 15, 2022 (BLE Project No. J21-7013-23) [FID 1747981] which included updated groundwater and surface water sample matrices. The SWS approved the CAER in a letter dated January 31, 2023 (FID 1768228). The SWS-approved monitoring matrix is included for reference (Table 1). The SWS issued a memorandum dated March 13, 2023 to all solid waste directors and landfill owners/operators. The memo requires that all groundwater, surface water, and leachate samples collected at solid waste sanitary landfills after July 1, 2023 be analyzed for Per- and Polyfluoroalkyl Substances (PFAS). The July 2024 event is the third event where PFAS monitoring was performed. The facility requires semi-annual groundwater, surface water, and leachate monitoring and reporting in accordance with the WQMP et seq. Semi-annual sampling is typically conducted each January and July and those events are designated “Winter” and “Summer,” respectively. This report represents the second semi- annual (Summer) sampling event of 2024. This single report encompasses the results from both the MSWLF/CDLF and the Subtitle D MSWLF. The existing groundwater monitoring network for the City of Albemarle Landfill consists of two (2) upgradient (background) wells and twenty-five (25) downgradient (compliance) wells. Background monitoring well MW-1RD was installed on May 11, 2022 to replace MW-1. MW-1RD is upgradient of the monitoring system of the active CDLF and closed MSWLF which includes MW-2, MW-3, MW-4R, MW-5R, MW-6, MW-7, MW-8D, MW-9, MW-10, MW-11, MW-12, MW-13, MW-23, MW-24, MW-25, and MW-29. Background monitoring well MW-19 is upgradient of the monitoring system of the active Subtitle D MSWLF which includes MW-14, MW-15, MW-16S, MW-16D, MW-17, MW-18, MW-22, MW-26, and MW-27. It is noted that all wells are sampled semi-annually except MW-24 and MW-25 which are sampled annually (summer events only). Additionally, groundwater monitoring well MW-28 was installed as part of a groundwater assessment but is not sampled as part of the groundwater compliance network. Semi-Annual Water Quality Report – Second Event 2024 December 13, 2024 City of Albemarle Landfill – Albemarle, North Carolina BLE Project No. J24-7013-31 2 of 5 In accordance with Rule .0602 and Rule .0544(c), five (5) surface water monitoring locations have been established for the facility to monitor surface water quality surrounding the existing waste footprint. The existing surface water locations consist of one (1) upstream (background) point (SW-1) and four (4) downstream (compliance) points (SW-2, SW-5, SW-7, and SW-8). Surface water locations SW-1, SW-5, SW-7, and SW-8 monitor the closed MSWLF and active CDLF while locations SW-1, SW-2, SW-7, and SW-8 monitor the active Subtitle D MSWLF. Locations SW-1, SW-7, and SW-8 monitor surface water along the unnamed tributary of Jacobs Creek that crosses in between the two landfills. SW-5 monitors surface water from the closed MSWLF and active CDLF and SW-2 monitors surface water from the active Subtitle D MSWLF. In accordance with Rule .1626(12)(c), one (1) active leachate sampling location has been established for the facility. The location is designated Leachate Lagoon. 2.0 FIELD ACTIVITIES, SAMPLING, AND ANALYSIS Groundwater, surface water, and leachate samples were collected between July 9-11, 2024 by personnel from Pace Analytical Services, LLC. (Pace). Groundwater samples were collected from the twenty-seven active groundwater monitoring well locations. All five (5) surface water locations were dry; therefore no samples were taken. Additionally, the one (1) leachate lagoon location was sampled. The groundwater and leachate samples were analyzed by Pace in their Asheville, NC, Charlotte, NC, and Minneapolis, MN, laboratories per the approved monitoring matrix (Table 1). The field parameters of pH, specific conductance, temperature, turbidity, dissolved oxygen, and redox potential were measured in the field by Pace. A copy of the Pace field sampling logs is included in Appendix A. A copy of the laboratory analytical data is included in Appendix B. 3.0 GROUNDWATER FLOW The water level data collected during the semi-annual sampling event on July 8, 2024 are presented in Table 2. Groundwater flow velocity estimates are presented on Table 3. A groundwater elevation contour map with generalized groundwater flow directions is presented as Figure 2. Semi-Annual Water Quality Report – Second Event 2024 December 13, 2024 City of Albemarle Landfill – Albemarle, North Carolina BLE Project No. J24-7013-31 3 of 5 4.0 GROUNDWATER RESULTS 4.1 Active CDLF and Closed MSWLF The results of the groundwater field and laboratory analyses for the CDLF and closed MSWLF are summarized on Table 4 and Table 5 and the laboratory analytical data is included in Appendix B. Background monitoring well MW-1RD is included in these results. Please refer to Table 4 and Table 5 for a summary of which groundwater constituents exceed North Carolina Groundwater Quality Standards (NC2L) maximum contaminant levels1 (MCLs). Field parameters measured in the groundwater included pH, specific conductance, temperature, turbidity, dissolved oxygen, and redox potential. Please refer to Table 5 for a summary of measured field parameters. We note that several groundwater temperatures are not reported because accurate groundwater temperatures could not be measured due to the exposure of the flow through cell to direct sunlight and high ambient air temperature. 4.2 Active Subtitle D Lined MSWLF The results of the groundwater field and laboratory analyses for the active Subtitle D MSWLF are summarized on Table 4 and Table 5 and the laboratory analytical data is included in Appendix B. Background monitoring well MW-19 is included in these results. Please refer to Table 4 and Table 5 for a summary of which groundwater constituents exceed North Carolina Groundwater Quality Standards (NC2L) maximum contaminant levels1 (MCLs). Field parameters measured in the groundwater included pH, specific conductance, temperature, turbidity, dissolved oxygen, and redox potential. Please refer to Table 5 for a summary of measured field parameters. We note that several groundwater temperatures are not reported because accurate groundwater temperatures could not be measured due to the exposure of the flow through cell to direct sunlight and high ambient air temperature. 5.0 SURFACE WATER RESULTS The surface water was dry at the time of sampling therefore there are no field or laboratory analytical data. The results of the surface water field and laboratory analyses are summarized on Table 6 and Table 7. 6.0 PFAS RESULTS The results of the PFAS analytical data are summarized in Table 8A (groundwater for active C&D and Closed MSW), Table 8B (groundwater for Subtitle D MSW), and Table 9 (surface water). The laboratory analytical data is included in Appendix B. Please refer to Table 8A, Table 8B, and Table 9 for a summary of which constituents exceeded their Health Advisory, Regional Screening Level, and/or MCL. 1 North Carolina Department of Environmental Quality, Groundwater Classification and Standards, Section 15A NCAC 2L.202, April 1, 2022. Semi-Annual Water Quality Report – Second Event 2024 December 13, 2024 City of Albemarle Landfill – Albemarle, North Carolina BLE Project No. J24-7013-31 4 of 5 7.0 SUMMARY 7.1 General Semi-annual assessment monitoring was performed during the second semi-annual event of 2024 in general accordance with the approved WQMP and Matrix (Table 1). Detected constituents which exceed their respective groundwater and surface water standards (if any) are identified on the summary tables. The July 2024 results are similar to the prior January 2024 monitoring event, except for all five (5) surface water locations being dry. This is the third monitoring event where PFAS has been sampled. We recommend that semi-annual sampling continue in accordance with the approved plans and matrices. 7.2 Alternate Groundwater Protection Standards from Background The facility has calculated alternate groundwater protection standards (AGWPS) from background concentrations for arsenic, cobalt, and vanadium which were approved by the SWS on April 14, 2020. Those AGWPS are utilized in this report. The SWS has directed the facility to calculate AGWPS for iron and manganese from background concentrations using ten (10) non-turbid groundwater samples from the background well (MW-1). As of April 2020, seven (7) non-turbid groundwater samples had been collected from MW-1. The sampling crew was unable to obtain a non-turbid sample from MW-1 during the July 2020 sampling event. An additional sampling event for metals in MW-1 was conducted on October 28, 2020. The sampling crew was unable to obtain a non-turbid sample from MW-1 during the October 2020 event and did not submit a sample to the laboratory for analysis. It is noted that the sampling crew employed several potential turbidity- reducing sampling techniques but were not successful. The sampling crew was unable to obtain non-turbid samples as part of the January 2022 sampling event. As of January 2022, one (1) non-turbid background sample was still required for compliance with the SWS directive. The facility evaluated the efficacy of background groundwater monitoring well MW-1 and determined that a replacement groundwater well should be installed. The facility sent an informal request to abandon and replace MW-1 which was subsequently approved by the SWS in an email dated February 2, 2022. The replacement well, MW-1RD was installed on May 11, 2022 and was sampled on October 7, 2022. A non- turbid sample was collected from the new well. This sample constituted the tenth non-turbid sample required by the SWS to calculate AGWPS for iron and manganese. We understand from the SWS that the data collected from MW-1 is still valid and can be applied to the AGWPS calculation. A separate stand-alone document evaluating the metals concentrations at the facility will be submitted to the SWS in the future under separate cover. 7.3 Corrective Action The SWS has approved a corrective action plan (CAP) for the subject facility. The approved remedy in the CAP is monitored natural attenuation (MNA). The groundwater impacts have been classified as two physical incidents in the waste units within the permitted 8401-CDLF-1997 area. The area designated as East Plume is present in the closed MSWLF area and includes groundwater monitoring wells MW-3, MW-9, and MW- 10. The area designated as West Plume is present in the active C&D area and includes groundwater Semi-Annual Water Quality Report – Second Event 2024 December 13, 2024 City of Albemarle Landfill – Albemarle, North Carolina BLE Project No. J24-7013-31 5 of 5 monitoring wells MW-2, MW-6, MW-7, MW-24, and MW-25. The monitoring network for each plume also includes the background well MW-1RD which was installed on May 11, 2022 to replace MW-1. Prior to 2023, groundwater monitoring for MNA parameters was required for the East Plume on a 2-year frequency and for the West Plume on a 4-year frequency. We understand that the bifurcated MNA sampling schedule was adopted in 2013. Stand-alone MNA monitoring reports were prepared for these events in the past. The most recent MNA sampling event for the East Plume was performed in July 2021 and the most recent MNA sampling event for the West Plume was performed in July 2021. BLE prepared a Corrective Action Evaluation Report (CAER) to evaluate remedial status utilizing the results of the July 2021 event. Consolidation of the schedule into a single event was proposed as part of the CAER. The CAER was submitted by BLE on behalf of the City of Albemarle to the SWS on November 15, 2022 and was approved by the SWS on January 31, 2023. The next MNA sampling event is scheduled for July 2025 with the next CAER submitted thereafter. BLE prepared a Notice of Completion of Remedies on March 7, 2023 which documented the completion of the property acquisition, enhanced bioremediation, and phytoremediation remedies as described in the CAP. The MNA remedy continues to be implemented. 8.0 QUALIFICATIONS OF REPORT The activities and evaluative approaches used in this assessment are consistent with those normally employed in hydrogeological and environmental assessments of this type. Our evaluation of site conditions has been based on our understanding of the site and project information and the data provided to BLE. This report has been prepared on behalf of and exclusively for the use of the City of Albemarle, North Carolina. This report and the findings contained herein shall not, in whole or in part, be used or relied upon by any other party (excluding the SWS) without BLE’s prior written consent. 9.0 CLOSING We appreciate the opportunity to be of service to the City of Albemarle, North Carolina.

Hydraulic conductivity calculated by MESCO from slug tests performed upon well completions. 2. Effective porosity estimated by MESCO from Hamill & Bell, 1986 from Boring Records. 3. The hydraulic gradients were measured on the Groundwater Elevation Contour Map - July 8, 2024 (Figure 2). The high hydraulic gradient was measured between the 395-ft & 430-ft groundwater contours near MW-18 and MW-19. The low hydraulic gradient was measured between the 425-ft & 410-ft groundwater contours near MW-8D and MW-29. 4. Groundwater velocity derived from V = Ki/ne where: K = geometric mean hydraulic conductivity, i = hydraulic gradient, and ne = effective porosity. 5.

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. ANALYTE QUALIFIERS Constant weight could not be achieved for this sample after 4 drying cycles. The final weight change was .0021 grams.1g This analyte exceeded secondary source verification criteria low for the initial calibration. The reported results should be considered an estimated value.IL Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the associated samples may have a high bias.v1 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.v2 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the associated samples may have low bias.v3 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 07/23/2024 11:15 AM Pace Analytical Services, LLC 6701 Conference Drive Raleigh, NC 27607 (919)834-4984 Page 77 of 86 #=CR# QUALITY CONTROL DATA CROSS REFERENCE TABLE Pace Project No.: Project: 92740760 Semi-Annual MW Lab ID Sample ID QC Batch Method QC Batch Analytical Method Analytical Batch 92740760001 867464 867602MW-23 EPA 3010A EPA 6020B 92740760002 867464 867602MW-19 EPA 3010A EPA 6020B 92740760003 867464 867602MW-29 EPA 3010A EPA 6020B 92740760004 867464 867602MW-6 EPA 3010A EPA 6020B 92740760005 867464 867602MW-9 EPA 3010A EPA 6020B 92740760006 867464 867602MW-7 EPA 3010A EPA 6020B 92740760007 867464 867602MW-24 EPA 3010A EPA 6020B 92740760008 867464 867602MW-2 EPA 3010A EPA 6020B 92740760009 867464 867602MW-3 EPA 3010A EPA 6020B 92740760010 867464 867602MW-11 EPA 3010A EPA 6020B 92740760011 867464 867602MW-10 EPA 3010A EPA 6020B 92740760012 867464 867602MW-17 EPA 3010A EPA 6020B 92740760013 867464 867602MW-16D EPA 3010A EPA 6020B 92740760014 867464 867602MW-16S EPA 3010A EPA 6020B 92740760015 867464 867602MW-14 EPA 3010A EPA 6020B 92740760001 868078 868086MW-23 EPA 7470A EPA 7470A 92740760003 868078 868086MW-29 EPA 7470A EPA 7470A 92740760004 868078 868086MW-6 EPA 7470A EPA 7470A 92740760005 868078 868086MW-9 EPA 7470A EPA 7470A 92740760006 868078 868086MW-7 EPA 7470A EPA 7470A 92740760007 868078 868086MW-24 EPA 7470A EPA 7470A 92740760008 868078 868086MW-2 EPA 7470A EPA 7470A 92740760009 868078 868086MW-3 EPA 7470A EPA 7470A 92740760010 868078 868086MW-11 EPA 7470A EPA 7470A 92740760011 868078 868086MW-10 EPA 7470A EPA 7470A 92740760001 867499MW-23 EPA 8260D 92740760002 867499MW-19 EPA 8260D 92740760003 867499MW-29 EPA 8260D 92740760004 867499MW-6 EPA 8260D 92740760005 867500MW-9 EPA 8260D 92740760006 867500MW-7 EPA 8260D 92740760007 867500MW-24 EPA 8260D 92740760008 867500MW-2 EPA 8260D 92740760009 867500MW-3 EPA 8260D 92740760010 867500MW-11 EPA 8260D 92740760011 867500MW-10 EPA 8260D 92740760012 867500MW-17 EPA 8260D 92740760013 867500MW-16D EPA 8260D 92740760014 867500MW-16S EPA 8260D 92740760015 867500MW-14 EPA 8260D 92740760001 867138MW-23 EPA 8260D Mod. 92740760003 867138MW-29 EPA 8260D Mod. 92740760004 867138MW-6 EPA 8260D Mod. 92740760005 867138MW-9 EPA 8260D Mod. 92740760006 867138MW-7 EPA 8260D Mod. 92740760007 867138MW-24 EPA 8260D Mod. 92740760008 867138MW-2 EPA 8260D Mod.

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. ANALYTE QUALIFIERS This analyte exceeded secondary source verification criteria high for the initial calibration. The reported results should be considered an estimated value.IH The continuing calibration verification was above 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. ANALYTE QUALIFIERS Analyte was detected in the associated method blank.B This analyte exceeded secondary source verification criteria low for the initial calibration. The reported results should be considered an estimated value.IL Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1 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. ANALYTE QUALIFIERS 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.B2 Sample was diluted due to the presence of high levels of non-target analytes or other matrix interference.D3 This analyte exceeded secondary source verification criteria low for the initial calibration. The reported results should be considered an estimated value.IL Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1 RPD value was outside control limits.R1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the associated samples may have a high bias.v1 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.v2 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the associated samples may have low bias.v3 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 07/22/2024 09:36 AM Pace Analytical Services, LLC 6701 Conference Drive Raleigh, NC 27607 (919)834-4984 Page 33 of 39 #=CR# QUALITY CONTROL DATA CROSS REFERENCE TABLE Pace Project No.: Project: 92740432 Semi-Annual Leachate Lab ID Sample ID QC Batch Method QC Batch Analytical Method Analytical Batch 92740432001 867464 867602LagoonEPA 3010A EPA 6020B 92740432001 867499LagoonEPA 8260D 92740432002 867499TBEPA 8260D 92740432001 867138LagoonEPA 8260D Mod. 92740432001 868486LagoonSM 2320B-2011 92740432001 867018 867057LagoonSM 5210B-2016 SM 5210B-2016 92740432001 868838 869257LagoonEPA 365.1 Rev 2.0 1993 EPA 365.1 Rev 2.0 1993 92740432001 869080 869102LagoonSM 5220D-2011 SM 5220D-2011 92740432001 866853LagoonEPA 9056A REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 07/22/2024 09:36 AM Pace Analytical Services, LLC 6701 Conference Drive Raleigh, NC 27607 (919)834-4984 Page 34 of 39 Page 35 of 39 Page 36 of 39 Page 37 of 39 Pa g e 3 8 o f 3 9 Pa g e 3 9 o f 3 9 #=CL# August 05, 2024 LIMS USE: FR - DARREN PRESLAR LIMS OBJECT ID: 92740761 92740761 Project: Pace Project No.: RE: Darren Preslar ALBEMARLE (CITY OF) PO Box 190 Albemarle, NC 28002 Semi-Annual PFAS Dear Darren Preslar: Enclosed are the analytical results for sample(s) received by the laboratory on July 09, 2024.

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.

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.
