More than half of sewage sludge produced in the U.S. is applied on agricultural land as fertilizer, according to EPA data. They say such regulations unfairly penalize wastewater plants and the broader waste industry, which considers itself to be a passive receiver of PFAS contamination from upstream industrial sources. In 2003, the agency considered but decided not to regulate dioxins in sewage sludge used as fertilizer. In January, the EPA released a draft risk assessment of PFOS and PFOA, two chemicals in the PFAS family, in sewage sludge.
