According to the Michigan Department of Environmental Quality (MDEQ), two compounds of PFAS in drinking water were found at the Alto Elementary School in Kent County, Mich. The water tested positive for per- and polyfluorinated substances (PFAS).

The department found PFHxS at 21 parts per trillion (ppt), and PFBS at 2 ppt. There are no federal health advisories for PFAS in drinking water for either compound, but the advisory for PFOS and PFOA–related PFAS chemicals is set at a combined 70 ppt.
