A new bill would require the Environmental Protection Agency to do much more to regulate PFAs, a class of artificial chemicals that never fully break down and have made their way into waterways and food systems. The PFAs Action Act, introduced today by Reps. Debbie Dingell (D-Mich.) and Fred Upton (R-Mich.), would, among other things, establish a national drinking water standard and require the EPA to set limits on the amount of PFAs factories can release into the environment. “This is a bad substance and people need to warned about it.” PFAs (per- and polyfluoroalkyl substances) are pervasive in our daily lives.
