Iowa officials will test 58 more water supplies, including Dubuque’s, this summer for “forever chemicals” that can cause serious health conditions. The Iowa Department of Natural Resources will take finished water samples and raw water samples from two wells in the Dubuque drinking water supply to determine if they contain detectable amounts of perfluoroalkyl and polyfluoroalkyl substances, typically categorized as PFAS. Other area Iowa communities to be tested for the chemicals include Monticello and McGregor.
