Right now, the federal government doesn't require products that contain PFAS to be labeled, and doesn't check companies' claims that products are PFAS-free. But states are rising to the challenge.

Indiana manufacturers pushed to change the state's definition of toxic PFAS to ensure they can continue using some of those chemicals. That effort failed at the Statehouse. But we'll likely see more legislation like this as manufacturers try to hold on to chemicals the federal government wants to limit.

A bill that would change the definition of toxic PFAS to exclude chemicals Indiana manufacturers want to continue using passed the House on Tuesday.
