On August 16, 2019, EGLE released the report describing the findings from the 2018 PFAS Sampling of Drinking Water Supplies in Michigan. The report consists of the main body and four appendices.
The initial phase of statewide PFAS surveillance testing began in April 2018, and was originally conceived as a multi-year project covering drinking water for approximately 75% of Michigan’s residents. This effort initially included community water supplies, schools on their own well(s), and water supplies for Michigan’s federally-recognized tribes who chose to participate in this survey. In November 2018, sampling was expanded to also include child care providers and Michigan Head Start programs on their own well(s). Testing was ultimately done for the following supplies:
This sampling was completed in December 2018. Therefore, approximately 7.7 million of Michigan's 10 million residents have now had their drinking water tested for PFAS. The results of this testing are detailed in the interactive tables below. A summary report of the overall results is available to the right.
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has provided recommendations based on PFAS levels. View this notification protocol (pdf).
The Public Water Supplies dataset is available for download on the data.Michigan.gov open data portal. The tables below shows testing results from the statewide sampling initiative for Michigan public water supplies. Additional results from the testing will be added as they become available.
