PFAS manufacturers and chromium electroplating facilities may balk at the changes. Joel Johnston, an attorney with national law firm Hall Estill, says, “There is no doubt that the [affected] industries will have to implement new testing/sampling protocols and to treat/control their discharges to meet the new standards.” 

Johnston adds that although PFAS are widely known to be present in fire suppression chemicals, especially at airports, it is “notable” that the EPA has chosen not to regulate PFAS discharges associated with those operations.
