Contamination in an Oakland County creek that feeds into the Huron River and its chain of lakes is setting a new state record for PFAS present today in Michigan surface water.
Now the source of the pollution is under orders to outline steps it will take to reduce how much of the chemical it’s sending into the waterway by October 19.
Testing at Norton Creek by the state on July 24 showed a reading of 5,500 parts per trillion (ppt) of PFOS, an individual compound in the PFAS family of poly- and per-fluorinated “forever chemicals” linked to cancer and other health conditions, according to state environmental officials.
That level is more than 450 times what the state allows in surface waters and 78 times the lifetime health advisory for human consumption.
The PFOS concentration also exceeds most reported readings at Clark’s Marsh near the closed Wurtsmith Air Force Base in Oscoda. Testing for PFAS chemicals since 2011 placed that location at the top of the state’s […]
