The samples in this SDG were analyzed on an "as received" basis.
Data Summary:

All sample data provided in this report met the acceptance criteria specified in the analytical methods and
procedures for initial calibration, continuing calibration, instrument controls and process controls where
applicable, with the following exceptions.

Quality Control (QC) Information

Method Blank (MB) Statement
There was a confirmed hit of Perfluoropropanoic acid (PPF Acid) above PQL in the Method Blank (See Below).
PPF Acid is prone to interferences that adversely contribute to a positive bias.
Sample Analyte Value
1205158658 (MB)Perfluoropropanoic acid (PFPrA)4.42 * 10 > 4.95

Laboratory Control Sample (LCS) Recovery
The LCS and LCSD (See Below) did not meet spike recovery acceptance criteria for Byproduct 4, Byproduct 5,
and R-EVE. Samples with insufficient volumes remaining to allow for re-extraction were reported as is; all other
samples were re-extracted.

R-EVE 6* (22%-158%)

LCS/LCSD Relative Percent Difference (RPD) Statement
The relative percent difference between the LCS and LCSD (See Below) did not meet acceptance criteria for
Byproduct 4 and R-EVE. Both analytes recovered below SPC limits in the LCS and LCSD. Samples with
insufficient volumes remaining to allow for re-extraction were reported as is; all other samples were re-extracted.
Sample Analyte Value
1205158659 (LCS) and 1205158998 (LCSD)Nafion Byproduct 4 (PFESA BP4)RPD 69* (0%-45%)

Internal Standard (ISTD) Acceptance
Industrial samples 588585001 (TB080422-00), 588585003 (FT071922-21) and 588585004 (FTB071922-21) did
not meet acceptance criteria for one or more internal standards with a positive bias. The samples were diluted in
order to bring internal standards within acceptance criteria. The results for these samples were reported from the
undiluted and diluted analyses. Industrial sample 588585003 (FT071922-21) did not meet acceptance criteria for
one or more internal standards with a negative bias. The sample was diluted in order to bring internal standards
within acceptance criteria. There was insufficient volume remaining to allow for a re-extraction. The results for
this sample was reported from the undiluted and diluted analyses.

Technical Information

Sample Dilutions
The following samples and/or QC were diluted due to the Internal Standard Recovery not within the limits in the
undiluted analysis. 588585001 (TB080422-00), 588585003 (FT071922-21) and 588585004 (FTB071922-21).

Sample Re-extraction/Re-analysis

and 588585017 (D071922-21WD).

Miscellaneous Information

Additional Comments
The following samples had a responses for analytes on both columns or detectors that indicated an acceptable
peak within the retention time window and acceptable concentration match. Although method criteria have been
satisfied for reporting a positive result for these analytes, the result is considered a false positive due to matrix
interference and is indicated as such on the appropriate Form I with an X qualifier. A LCS/LCSD pair was
extracted and analyzed in place of sample matrix QC.

acceptance criteria for one or more internal standards with a positive bias. The samples were diluted in order to
bring internal standards within acceptance criteria. The results for these samples were reported from the
undiluted and diluted analyses.

Technical Information

Holding Time Specifications
Samples (See Below) were collected on 26-Jul-2022 for an extraction hold date of 09-Aug-2022. The samples
were received on 05-Aug-2022 and initially extracted within hold on 08-Aug-2022. However due to batch QC
failures the samples were re-extracted one day out of hold on 10-Aug-2022

Sample Dilutions
The following samples and/or QC were diluted due to the Internal Standard Recovery not within the limits in the
undiluted analysis. 588585002 (FB071922-32), 588585005 (D071922-MB), 588585006 (W071922-MB),

Miscellaneous Information

Additional Comments
Some analytes are X qualified because the standards used to make the initial calibration curve did not meet the
ISO 17025 criterion. These are the only standard available for these analytes. A LCS/LCSD pair was extracted
and analyzed in place of sample matrix QC.

Certification Statement

Where the analytical method has been performed under NELAP certification, the analysis has met all of the
requirements of the NELAC standard unless otherwise noted in the analytical case narrative.
