In an article by the AP, local residents in Wellston, OK, complain of the use of sewage sludge as fertilizer. This is just one story of many similar ones across the country. The biggest concern is the health risks from PFAS, or "forever chemicals," often found in untreated sewage sludge. PFAS don't degrade and can cause serious health issues for animals and humans as they contaminate the soil and water supply.
