As part of its effort to protect communities from per- and polyfluoroalkyl substances (PFAS), the Environmental Protection Agency has created a draft risk assessment modeling human exposure to the “forever chemicals” PFOA or PFOS from the application of sewage sludge, or biosolids, to farmland. This risk assessment does not model risks for the general public, only very specific populations living on or near sites affected by PFAS from biosolids.
EPA’s goal of the risk assessment is to inform future actions by federal and state agencies as well as steps that wastewater systems, farmers and other stakeholders can take to protect people from PFAS exposure, while also ensuring American industry keeps feeding and fueling the nation.
