Measurement evidence

Analyte: Perfluorooctanoic acid (PFOA)
Result qualifier: =
Reference basis: 4.0 ng/L federal MCL (2024)
Sampling location: Entry Point to Distribution
Water system ID: NJ1429001
Source ID: src-ucmr5-2024

Laboratory context

No laboratory method note was published with this record.

Sampling context

This result represents a entry point to distribution sample. It does not establish the condition at every distribution point or household tap.

Record limitation

System-level entry-point monitoring; not a measurement of the water at an individual household tap.

Source provenance

UCMR5 Analytical Results

Fifth Unregulated Contaminant Monitoring Rule (UCMR5) — PFAS occurrence data

U.S. Environmental Protection Agency · Published 2024

Nationwide entry-point monitoring for 29 PFAS and lithium under the fifth UCMR cycle. Results are entry-point-to-distribution samples, not household-tap measurements.

How to interpret this record

This page preserves one measurement. Interpretation requires its qualifier, reporting limit, reference basis, date, sampling location, and limitations; the number alone is not a safety verdict.
