Monthly test show a unique PFAS chemical is in the city's water.  WEMU's Heather Irvine has more.


A new PFAS chemical is appearing in Ann Arbor's drinking water.  The City of Ann Arbor tests drinking water and its river source monthly, and Water Treatment Services manager Brian Steglitz says recent data shows something new.

"There is a new chemical that seems like it's showing up that was previously non-detective.  It's called 6:2 FTS, which is a PFAS.

Ann Arbor is reaching out to those discharging into the Huron River about changes in the watershed but haven't received feedback.

Steglitz sees this as an opportunity to collaborate with regulator and other treatment works to research chemical changes together.  The city's treatment process in removing regulated PFAS, historically, is superior.

"You know we're tracking this regularly, and, at this point, the water quality that we're providing to all our customers well exceeds any current regulatory and health-based levels for any of these chemicals, and it's safe to drink."
