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.
