What is the Lifetime Health Advisory Level?

The U.S. Environmental Protection Agency (EPA) has set a lifetime health advisory (LHA) level for two PFAS in drinking water: perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). The PFOA and PFOS LHA is the level, or amount, below which no harm is expected from these chemicals. The LHA level is 70 parts per trillion (ppt) for PFOA and PFOS individually or combined. The LHA, protective of everyone, especially pregnant women, young children, and the elderly. Currently, the EPA has not set health advisory levels for the other PFAS chemicals.  (Source: https://www.michigan.gov/pfasresponse/)
