New York recently proposed additional drinking water standards. Falling in between the EPA and WHO numbers, New York's "maximum contaminant level" for perfluorodecanoic acid (PFDA) perfluoroheptanoic acid (PFHpA), perfluorohexane sulfonic acid (PFHxS) and perfluorononanoic Acid (PFNA) under the proposed rule would be set at 10 ppt and 30 ppt combined for PFOS, PFOA, PFDA, PFHpA, PFHxS and PFNA. The New York Department of Health estimates it will immediately see a 1.46 percent increase in violations for each of the four newly regulated PFAS if the standards are finalized at 10 ppt.
