Maine plans removal of PFAS from sewage sludge used as fertilizer

State officials ordered Lapeer to stop distributing its sludge for use as farm fertilizer after it was found to contain toxic PFAS chemicals. Experts are raising concerns that sludge spread on agricultural fields around the U.S. could contaminate crops. About half of the 7 million tons of sludge generated each year is applied to farm fields and other lands. (AP Photo/John Flesher)
