Studying Social, Scientific, and Political Factors of Per- and Polyfluoroalkyl Substances

Ann Arbor Municipal Water Treatment Plant, Ann Arbor MI

The Ann Arbor Municipal Water Treatment Plant provides water from the Huron River, which has been contaminated with PFAS chemicals by an unknown source.

The first drinking water samples for PFAS compounds were taken in March 2014, as required by the EPA, when PFOS was detected in the drinking water. The city informed its customers and underwent investigative sampling that identified the Huron River as the source of contamination. While the origin of PFOS in the river is currently unknown, the city is conducting monitoring and regular updates to the public.
