More Information: PFAS Information & Sampling Project
Abbreviations: MCL = Maximum contaminant level, MRL = Minimum reporting level, ND = Not detected at the minimum reporting level, PFAS = Per- and polyfluoroalkyl substances. Analytes with an MCL are in bold. Sample results detected above the MCL are in bold red.
Water systems must be in compliance with the MCL by 2029. Sample results can be used for compliance when their MRL meets the requirements of the PFAS rule. Results that cannot be used for compliance are shaded gray and italicized.
