Illinois failed to act even though it knew 3M had been polluting the Mississippi River for more than a decade – Chicago Tribune/MSN

There are signs the chemicals have spread well beyond 3M’s property in Cordova. Contractors found at least two PFAS in three of eight public water systems and 68 of 72 private wells tested in Illinois and Iowa during the summer. The most alarming levels were detected on the Illinois side of the river, where concentrations of one PFAS in private wells were up to 6,250 times higher than the EPA’s latest health advisory.
