The largest PFAS technical conference to-date highlighted the latest research on these contaminants and emphasized opportunities for collaboration on solutions for addressing PFAS contamination in Michigan and globally.

The multi-state agency MPART organization was established under an executive order to ensure coordination in implementing a response to PFAS contamination.  PFAS, also known as per- and polyfluoroalkyl substances, are a large group of manmade chemicals that have been used globally during the past century in manufacturing, firefighting and thousands of common household and other consumer products. These chemicals are persistent in the environment and in the human body – meaning they don’t break down and can accumulate over time. 

Michigan has been investigating PFAS contamination statewide since 2017.  MPART has identified 232 sites in the state with known PFAS contamination impacting the groundwater -- and in some cases impacting the drinking water.  In 2018, Michigan was the first state in the nation to test every public drinking water supply in the state.  This represents roughly 75 percent of the state’s population.  The state’s ongoing groundwater and site investigations are also helping identify PFAS risks for roughly 1.2 million homes with residential wells.
