Michigan PFAS Exposure and Health Study (MiPEHS)

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 (planned for 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.
