Summary
Reanalysis of state drinking-water compliance data by community characteristics. Filed as secondary context without new concentration rows.
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)
Secondary monitoring-data analysis, PDF pp2-4. Source collection and aggregation rules remain those of the state dataset; no laboratory method inferred from the MANIFEST.
Detection limits and censoring: Table captions and main text differ in assignments of regulatory values (PDF pp2 and 4). These are logged and excluded from evidence rows.
Limitations
- REGULATORY_VALUE_ASSIGNMENT: Main text PFOA14/PFOS13 ng/L. Comparison: Table captions PFOA13/PFOS14 ng/L. Locator: PDF p2 versus p4 Tables 1-2 captions. No regulatory values emitted; log only without correction.
