The utility was among the many first within the state to deal with the problem after exams final 12 months revealed its handled ingesting water had a mixed focus of the 2 most-prominent PFAS of 5.3 elements per trillion. On the time, it was nicely under the federal advisory of 70 elements per trillion, however in June the EPA decreased that to .004 elements per trillion for one of many PFAS and .02 elements per trillion for the opposite.

The Iowa Division of Pure Assets has found PFAS in a few dozen neighborhood ingesting water provides within the state prior to now 12 months.
