Summary
Key numbers
Source-reported values checked against the cited page of the filed PDF. Values are reported as printed, without conversion. These are selected records, not an exhaustive transcription.
| analyte | value | unit | basis | source location | limits and qualifiers |
|---|---|---|---|---|---|
| PFBS | 0.70 | ng/L | bottled-water mean as printed; non-detect mean retained literally | PDF p. 8, Table 1, Bottled Water Mean | |
| PFHxA | 0.24 | ng/L | bottled-water mean as printed; non-detect mean retained literally | PDF p. 8, Table 1, Bottled Water Mean | |
| PFHxS | <LOQ | ng/L | bottled-water mean as printed; non-detect mean retained literally | PDF p. 8, Table 1, Bottled Water Mean | |
| PFOA | 4.04 | ng/L | bottled-water mean as printed; non-detect mean retained literally | PDF p. 8, Table 1, Bottled Water Mean | |
| PFNA | 0.08 | ng/L | bottled-water mean as printed; non-detect mean retained literally | PDF p. 8, Table 1, Bottled Water Mean | |
| PFOS | 0.09 | ng/L | bottled-water mean as printed; non-detect mean retained literally | PDF p. 8, Table 1, Bottled Water Mean | |
| PFDA | 0.07 | ng/L | bottled-water mean as printed; non-detect mean retained literally | PDF p. 8, Table 1, Bottled Water Mean | |

Evidence Fitness
Bounded transcription of selected occurrence statistics, not a complete numeric extraction of the paper. Other matrices, risk calculations, regulatory limits and literature comparisons are excluded.
Methods (brief)
SPE with weak-anion-exchange sorbent followed by LC-MS/MS in MRM mode, PDF pp. 3-4. The EPA Method 533 native analyte standard is named; this alone does not establish full method compliance.
Target labels as printed: PFBA; PFBS; PFHxA; PFPeA; PFHpA; PFHxS; PFHpS; PFOA; PFNA; PFOS; PFDA; PFNS; PFDoDA; PFDS; PFUnDA (Table 1); PFMPA; 4:2 FTSA; HFPO-DA; NFDHA; PFEESA; PFMBA; DONA; 6:2 FTSA; 9Cl-PF3ONS; 8:2 FTSA; 11Cl-PF3OUdS; PFOSA (Table 2).
Detection and quantification limits: LOD 0.02 ng/L and LOQ 0.06 ng/L for all targeted compounds, PDF p. 5, section 2.5. Table 1 <LOQ is retained.
Limitations
Supplementary Tables S1-S11 are not deposited. Abstract composition proportions differ from the tabulated regulated/unregulated means when interpreted as the same denominator, so no proportions are routed. Table means have unspecified nondetect treatment. All tap-water and risk calculations excluded.
Provenance notes
DOI and citation metadata checked against the deposited PDF title page; no online resolution attempted. MANIFEST identity matched. PDF copied without modification; raw_path and sha256 retain local provenance. All printed values and censoring retained without conversion or conflict repair.
