The Michigan PFAS Exposure and Health Study (MiPEHS) is one of the most comprehensive and cutting-edge investigations into the health effects of PFAS exposure being conducted in the country.
MiPEHS is a large, longitudinal (or long-term) study designed to examine the health of Michiganders with past exposure to PFAS in their drinking water. MiPEHS has three phases: Phase 1 (2020-2021), Phase 2 (2023), and Phase 3 (2025).
The ongoing success of MiPEHS would not be possible without our participants, who are making important contributions to their community, as well as to scientific knowledge and public health.
MiPEHS data collection ended 8/16/2025 and we are not enrolling participants. But stay tuned! The team is analyzing the data and will post reports as they are available.
Some results from Phase 1 (2020-2021) are in! Visit the Phase 1 Summary Report page or click each document below to see what we've learned so far during the first phase.
