This letter report presents the results of the recently completed leachate sampling event at the Onslow County Subtitle D Landfill. Leachate samples from the Onslow County Subtitle D Landfill were collected on October 10, 2024. Table 1 presents water quality parameters at the time of sampling. Each sample 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 Geotech portable turbidity meter. Samples were collected from the sumps at Phase 1A (Station #1), Phase 1B (Station #2), Phase 1C (Station #3), Phase 2 (Stations #4 and #5), Phases 3 and 4 (Station #6), and Phase 5 (Station 7). Enthalpy Analytical, LLC located in Richmond, Virginia and Wilmington, North Carolina analyzed the leachate samples for North Carolina Appendix I volatile organic compounds and metals, 1,4-dioxane, biological oxygen demand, chemical oxygen demand, nitrate, phosphorus, sulfate, ammonia, and per- and polyfluorinated substances. Laboratory analytical results are provided in Appendix A. A copy of this report will be placed in the operating record for the facility. If you have any questions or require further explanation, do not hesitate to call me at (919) 325-3500.

The Standards that did not were: • 1633 CS2 SID BF29 (13C2-4:2 FTS, d3-N-MeFOSAA) • 1633 CS3 SID BF28 (13C2-4:2 FTS, 8:2 FTS, d3-N-MeFOSAA) • 1633 CS4 SID BF27 (4:2 FTS, 6:2 FTS) • 1633 CS5 SID BF26 (4:2 FTS, 6:2 FTS, d3-N-MeFOSA, d3-N-MeFOSAA, d5-N-EtFOSAA) Select analytes and surrogates exceeded method control limits in the concals and/or sensitivity check. Impacted analytes were not detected >LOQ in the samples. The data is reported with no adverse impact. 5. QC Notes The QC sample analyses passed all method criteria, except for the following: LLOPR_18453_PFAS: PFHxS and PFOS are 'B' flagged in the LLOPR because the extract recovery amount is less than 10 times that detected in the MB. This analyte meets recovery criteria in these QC samples and the data is accepted with no further action. DOD QSM Table B-24 (EPA 1633) -non-potable water samples were extracted within 28 days, and extracts analyzed within 28 days.

Reporting Notes The results presented in this report are representative of the samples as provided to the laboratory. PFHxS is 'B' flagged in samples Station 1 (1024-774-009-1A), Station 2 (1024-774-010-1A), Station 3 (1024-774-011-1A), Station 5 (1024-774-013-1A) and Station 6 (1024-774-014-1A) because the extract recovery amount is less than 10 times that detected in the MB. This analyte meets recovery criteria and the data is accepted with no further action. PFOS is 'B' flagged in samples MW-8 (1024-774-006-1A) because the extract recovery amount is less than 10 times that detected in the MB. This analyte meets recovery criteria and the data is accepted with no further action. Samples MW-5 (1), MW-2, MW-4 and MW-11 were initially injected using Sciex Triple Quad 7500 (LC/MS/MS "Starscream") and contained surrogates (ES) M5PFPeA and M8PFOSA that deviated from method criteria. The sample extracts were treated to a dilution factor of two (D2) and re-injected using Waters Acquity UPLC equipped with Xevo TQ MS (LC/MS/MS "Pippin"). Results exceeded method recovery criteria of 5% for dilution analysis; therefore, the data is reported with no adverse impact. The ion ratios for all compounds were within tolerance. The following samples had manual integrations on one or more peaks.

EU 1024-774 Page 9 of 112 General Reporting Notes – Data Qualifiers EU116_v8 (General Reporting Notes-Data Qualifiers) Enthalpy Analytical, LLC – Wilmington, NC The following are general reporting notes that are applicable to all Enthalpy Analytical, LLC - Wilmington, NC data reports, unless specifically noted otherwise. General Data Qualifiers  Ac - Alternate calculation flag indicates the es recovery was calculated using the opening concal when either of the following situations is encountered in the data processing software: the ES recovery is over 400% or the JS is not detected.  B – The analyte was found in the method blank, at a concentration that was at least 10% of the amount in the sample.  Cxx – Two or more congeners co-elute. In EDDs, C denotes the lowest IUPAC congener in a co- elution group and additional co-eluters for the group (‘xx’) are shown with the number of the lowest IUPAC co-eluter.  E – The reported concentration exceeds the calibration range (upper point of the calibration curve). For HRMS data, this condition does not imply additional measurement uncertainty. For LC-MS/MS data, these values should be considered as having measurement uncertainty higher than values within the calibration range.  EDL – Estimated Detection Level: The EDL is unique to isotope dilution methods and reflects the conditions of analysis at the time of analysis, including the equipment used. Where the MDL is a static value, the EDL is a dynamic value.  EMPC – Estimated Maximum Possible Concentration: EMPC is specific to Dioxin/Furan tests to indicate the determined ion-abundance ratio was outside the allowed theoretical range (usually due to being near the detection limit, although it can very rarely be caused by a co-eluting interference). The EMPC concentration is adjusted to reflect the value at the theoretical ion- abundance ratio.  I/IR – The ion ratio between the primary and secondary ions was observed to be outside the method criteria. The analyte concentration may be inaccurate due to interference.  J – The analyte has a concentration below the minimum calibration level (LOQ value) but greater than the LOD. These values should be considered as having measurement uncertainty higher than values within the calibration range  L - For reports containing PFAS analytes only, this flag indicates that an analyte has a concentration below the Minimum Detection Limit (MDL) . The reported concentration is not recommended for regulatory use as the analyte signal may have a signal-to-noise ratio less than the criteria deemed necessary to be considered a detected analyte.  LOD – Limit of Detection: For reports conforming to the DOD ELAP QSM, this is the QSM- defined LOD. For reports conforming to TNI requirements (but not DOD ELAP QSM requirements), this value is the minimum detection limit (MDL). The LOD is adjusted for sample weight or volume. EU 1024-774 Page 10 of 112 General Reporting Notes – Data Qualifiers EU116_v8 (General Reporting Notes-Data Qualifiers) Enthalpy Analytical, LLC – Wilmington, NC  LOQ – Limit of Quantitation: For reports conforming to the DOD ELAP QSM, this is the QSM- defined LOQ. For reports conforming to TNI requirements (but not DOD ELAP QSM requirements), this value is the reporting limit (RL). The LOQ is adjusted for sample weight or volume.  <LOD() – Analyte was not found at a concentration high enough to be reported as detected. It is reported as less than the LOD, and the LOD is given in the parentheses.  <LOQ() – Analyte was not found at a concentration high enough to be reported as above the QSM-defined LOQ or TNI defined Reporting Limit. It is reported as less than the LOQ, and the LOQ is given in the parentheses.  ND – Indicates a non-detect.  NR – Indicates a value that is not reportable due to issues observed in sample preparation or analysis.  PR – The associated congener(s) is(are) poorly resolved.  QI – Indicates the presence of a quantitative interference.  RL – Reporting Limit. Lowest reportable value. The level is higher than the MDL.  SI – Denotes “Single Ion Mode” and is utilized for PCBs where the secondary ion trace has a significantly elevated noise level due to background PFK. Responses for such peaks are calculated using an EMPC approach based solely on the primary ion area(s) and may be considered estimates.  U – The analyte was not detected.  V / Q – The labeled standard recovery is not within method control limits.  X – Indicates the result is from re-injection/repeat/second-column analysis. Lab Identifiers/ Data Attributes  AR – Indicates use of the archived portion of the sample extract.  CU – Indicates a sample that required additional clean-up prior to HRMS injection/processing.  D – Dilution Data. Result was obtained from the analysis of a dilution. The number that follows the “D” indicates the dilution factor.  DE – Indicates a dilution performed with the addition of ES (Extraction Standard) solution.  DUP – Designation for a duplicate sample.  MS – Designation for a matrix spike.  MSD – Designation for a matrix spike duplicate. EU 1024-774 Page 11 of 112 General Reporting Notes – Data Qualifiers EU116_v8 (General Reporting Notes-Data Qualifiers) Enthalpy Analytical, LLC – Wilmington, NC  R – Indicates a re-extraction of the sample.  RJ – Indicates a reinjection of the sample extract.  S – Indicates a sample split. The number that follows the “S” indicates the split factor.  SAT – Indicates an analyte saturated the detector.
