From the Associated Press — Three members of Congress from Michigan want to make federal funds more readily available to clean up public water supplies contaminated with a group of toxic chemicals. The lawmakers have introduced a bill that would classify the substances known as PFAS as hazardous substances under the federal Superfund law. The designation would require the Environmental Protection Agency to report releases of the chemicals into the environment and clean up tainted sites. It also allows the government to sue polluters to recoup cleanup costs. EPA tests have found pollution from PFAS, or per- and polyfluoroalkyl substances, in public water supplies for 16 million Americans in 33 states, including Michigan. Democratic Reps. Debbie Dingell and Dan Kildee and Republican Rep. Fred Upton of Michigan are sponsoring the legislation.
