Summary
Produced drinking water and raw source water are separate. Selected produced-water statistics preserve linear and branched sums as printed; no raw-water row is routed as tap water.
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.

Evidence Fitness
Source classification: primary_measurement. MANIFEST tier: PRIMARY. This is a selected, bounded transcription, not an exhaustive extraction of every result in the paper. Each selected number has its own PDF page or table locator. Values for different matrices, isomers, statistics and aggregate assays are not interchangeable.
Methods (brief)
UHPLC-QTOF-HRMS targeted analysis, with a separate triple-quadrupole LC-MS/MS assay for HFPO-DA; PDF p3, Instrumental Analysis. Linear and branched isomers are separated. Target list in Table 2 and supporting information.
Detection limits and censoring: Individual values below LOD replaced by LOD/2 for statistical analysis, PDF p3. Numeric analyte LODs are in unstaged supplementary tables; summary medians can include substitution.
Limitations
- BODY_TABLE_RANGE_CONFLICT: Body PFOA range 0.04-8.6 ng/L; PFOS 0.05-4.3 ng/L. Comparison: Table 2 sum PFOA max8.7 and groundwater min0.07; sum PFOS groundwater min0.02. Locator: PDF p8 narrative versus p5 Table 2. Retain Table 2 values, source censoring and isomer scope; no reconciliation.
