Earlier this month, EPA set new lifetime health advisories for four per- and poly-fluoroalkyl substances (PFAS) – in some instances at levels lower than those that can be detected through laboratory testing. The new health advisories are listed below:
PFAS | Health Advisory (in parts per trillion) |
PFOA (perflurooctanoic acid) | 0.004 ppt |
PFOS (perfluorooctane sulfonic acid) |
