Michigan Public Water Supply PFAS Statewide Surveillance

The data includes information on the State of Michigan funded drinking water Per- and Polyfluoroalkyl Substances (PFAS) sampling effort, including, but not limited to, sample location, sample date, sample results, etc. This data is static and will not be updated. The data in this table includes all associated PFAS sample result data between 2018 and August 2, 2020, prior to the promulgation of Michigan’s PFAS maximum contaminant levels (MCLs). The units for all drinking water PFAS results are measured in PPT (parts per trillion), equivalent to ng/l.
