The EPA in June set the advisory level at 10 parts per trillion (ppt) for either HFPO-DA or its salt. A drinking water health advisory means the EPA recommends that utilities notify customers when concentrations of a contaminant exceed the level—it is not a regulatory limit, nor does it require any action by Chemours.
