More Information: PFAS Information & Sampling Project
*MCL = Maximum Contaminant Level. Analytes with an MCL are in bold; if it is detected and the MCL is exceeded for that sample, the result is in bold red. MRL = Minimum reporting level. ND = Not detected at the minimum reporting level. Systems must be in compliance with the MCL by 2029. PFAS = Per- and polyfluoroalkyl substances.
