The City of Ann Arbor Water Treatment Plant has taken voluntary steps to enhance the removal of per- and polyfluoroalkyl substances (PFAS) from drinking water.

  • The city began piloting the new filtration technology in fall 2017 to replace the current granular activated carbon (GAC) technology, and installed new GAC filters to improve PFAS removal.
  • In 2018, the city was awarded a grant by The Water Research Foundation to continue to study and refine techniques to remove PFAS compounds from drinking water.
  • The city partners with local organizations, such as the Huron River Watershed Council, to protect the city's drinking water sources from further PFAS contamination.
