Key Terms

UCMR 5▾

The 5th Unregulated Contaminant Monitoring Rule — an EPA program requiring large water systems to test for emerging contaminants, including PFAS, from 2023–2025.

PFAS▾

Per- and polyfluoroalkyl substances. A family of synthetic chemicals used in industry and consumer products, some of which have been detected in drinking water.

MRL (Minimum Reporting Limit)▾

The lowest concentration at which a lab can reliably detect and report a substance. Results below MRL are reported as non-detects.

Detection above MRL▾

The analyte was measured at a concentration at or above the minimum reporting limit. This is a monitoring result, not a compliance determination.

Non-detect▾

The analyte was tested but not found above the minimum reporting limit. Absence of detection does not guarantee absence of the substance.

This page shows only official government PFAS records. No risk scores, safety judgments, or inferred compliance determinations are generated by this system. Read methodology
