Summary
State monitoring is predominantly of raw source wells; treated/distribution samples are a subset. No mixed monitoring statistic is routed as a finished tap-water concentration (PDF pp3-4). Serum measurements and statistical associations are also excluded.
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.
No values from this source are published. It is filed as method or context evidence.
Evidence Fitness
Source classification: secondary_monitoring_analysis. MANIFEST tier: SUPPORTIVE. 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)
Regional laboratory EPA Method 537.1 results; monitoring and aggregation described in PDF p3.
Detection limits and censoring: PFOA and PFOS CCRDL 4 ng/L, PDF p4 Table 2. CCRDL is the monitoring reporting rule, not a newly measured laboratory LOD.
Limitations
- MIXED_WATER_MATRIX: MANIFEST describes public-water-system drinking water. Comparison: Most observations are raw source wells; finished concentrations cannot be estimated. Locator: PDF pp3-4 Methods. File supportive context only; no finished tap-water occurrence rows.
- PUBLICATION_YEAR: MANIFEST citation year 2025. Comparison: PDF journal citation year 2026; copyright 2025. Locator: PDF pp1 and 4. Use printed journal year in citation metadata; retain both dates in provenance.
Provenance notes
Citation metadata verified against PDF p1, title, author byline, journal citation or masthead, and DOI.. Article DOI appears in the supplied PDF and matches the MANIFEST case-insensitively. Original file: 2025_Fillman_associations-between-pfas-in-public-water.pdf. SHA-256: d5cbcae0cb491088d3ab3efd0dcafc1c417fdabb212f4b3d50dbf040254b645d. Original MANIFEST remains in the copied packet; discrepancies are listed without modifying it. Commercial analyte synonyms, instrument brands and manufacturer names are generalized in authored index prose.
