must include a preliminary analysis of the cause and significance of each value. (e.g. naturally occurring, off-site source, pre-existing
condition, etc.).
Attach a notification table of any groundwater or surface water values that equal or exceed the reporting limits.
Attach a notification table of any methane gas values that attain or exceed explosive gas levels. This includes any structures on or nearby the
facility (NCAC 13B .1629 (4)(a)(i).
Send the original signed and sealed form, any tables, and Electronic Data Deliverable to: Compliance Unit, NCDENR-DWM, Solid Waste

Dear Seth C. Rickerts:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 4/12/2024 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Angela D Overcash Senior Project Manager

Volatile Organic Compounds - GC/MS Method 8260D Analyte: 2-Butanone QC Batch No: V46476/V46475 Target analyte did not meet calibration verification criteria. Analysis of a low level check demonstrated that there was adequate sensitivity to report this compound at the laboratory reporting limit as non-detect. Analyte: 2-Butanone QC Batch No: V46536/V46475 This target analyte was flagged for recoveries outside QC limits in the associated LCS/LCSD. Data for this analyte is flagged "M" to indicate that results should be considered minimum concentration due to the potential for a low bias.

Job Narrative752-18645-1
ReceiptThesamples were received on 4/11/2024 12:38 PM.Unless otherwise noted below,the samples arrived in good condition,and,
where required,properly preserved and on ice.The temperature of the cooler at receipt time was 3.8°C.
PFAS
Method 1633:The following samples were diluted due to the nature of the sample matrix:MW-7 (752-18645-7),MW-8
(752-18645-8)and MW-9A (752-18645-9).Elevated reporting limits (RLs)are provided.
Method 1633:The laboratory control sample (LCS)and /or laboratory control sample duplicate (LCSD)for preparation batch680-834341 and analytical batch 680-834521 recovered outside control limits for the following analytes:Perfluoropentanoic acid
(PFPeA),Perfluorotridecanoic acid (PFTrDA),1H,1H,2H,2H-Perfluorohexane sulfonic acid (4:2 FTS),1H,1H,2H,2H-
Perfluorooctane sulfonic acid (6:2 FTS),1H,1H,2H,2H-Perfluorodecane sulfonic acid (8:2 FTS),Hexafluoropropylene Oxide Dimer
Acid (HFPO-DA),Perfluoro-4-methoxybutanoic acid (PFMBA),Nonafluoro-3,6-dioxaheptanoic acid (NFDHA),3-
Perfluoropropylpropanoic acid (3:3 FTCA),3-Perfluoropentylpropanoic acid (5:3 FTCA)and Perfluoro-3-methoxypropanoic acid
(PFMPA).These analytes were biased high in the LCS and were not detected above the RL in the associated samples;therefore,
the data have been reported.
Method 1633:The low level laboratory control sample (LLCS)for preparation batch 680-834341 and analytical batch 680-834521
recovered outside control limits for the following analytes:Hexafluoropropylene Oxide Dimer Acid (HFPO-DA),Perfluoro-4-
methoxybutanoic acid (PFMBA),Nonafluoro-3,6-dioxaheptanoic acid (NFDHA),3-Perfluoropropylpropanoic acid (3:3 FTCA)and
Perfluoro-3-methoxypropanoic acid (PFMPA).These analytes were biased high in the LLCS and were not detected in the
associated samples;therefore,the data have been reported.
Method 1633:Isotope Dilution Analyte (IDA)recovery is above the method recommended limit for the following sample:MW-1(752-18645-1).Quantitation by isotope dilution generally precludes any adverse effect on data quality due to elevated IDA
recoveries.
Method 1633:The continuing calibration verification (CCV)associated with batch 680-834521 recovered above the upper control
limit for Nonafluoro-3,6-dioxaheptanoic acid (NFDHA).The samples associated with this CCV were non-detects for the affected
analytes;therefore,the data have been reported.The associated samples are impacted:(CCV 680-834521/15),(CCV
680-834521/27),(CCV 680-834521/3)and (CCV 680-834521/37).
Method 1633:The Isotope Dilution Analyte (IDA)recovery associated with the following samples is below the method
recommended limit:MW-2A (752-18645-2),MW-3 (752-18645-3)and MW-4 (752-18645-4).Generally,data quality is not
considered affected if the IDA signal-to-noise ratio is greater than 10:1,which is achieved for all IDA in the sample(s).
Method 1633:The laboratory control sample (LCS)and /or laboratory control sample duplicate (LCSD)for preparation batch
680-834781 and analytical batch 680-834849 recovered marginally outside control limits for the following analytes:
Perfluorobutanoic acid (PFBA).The sample was re-extracted and re-analyzed with concurring results;therefore,the data havebeenreported.
Method 1633:The following samples in preparation batch 680-835499 were observed to have floating particulates present in the
sample bottle.
Method 1633:The laboratory control sample duplicate (LCSD)for preparation batch 680-835499 and analytical batch 680-835564
recovered outside control limits for the following analytes:Perfluorobutanoic acid (PFBA).The sample was re-extracted and re-
analyzed with concurring results;therefore,the data have been reported.
Method 1633:Internal standard (ISTD)response for the following sample was outside control limits:MW-10A (752-18645-10).The
sample(s)was re-extracted and/or re-analyzed and ISTD response was again outside control limits.
Method 1633:Internal standard (ISTD)response for the following sample was outside control limits:MW-3 (752-18645-3).The
sample(s)was re-extracted and/or re-analyzed and ISTD response was again outside control limits.
No additional analytical or quality issues were noted,other than those described above or in the Definitions/Glossary page.
