The suggestion that the EPA would take steps toward creating a maximum contaminant level — a standard for how much of the chemicals is safe to drink — for PFOA and PFOS, two types of PFAS, could run contrary to a Politico report last month that the EPA would not pursue a drinking water limit for the chemicals. That report sparked outrage from environmentalists and elected officials, and drew suggestions that PFAS could be an issue in Wheeler’s confirmation to the administrator post.
