The E.P.A.’s report follows a growing body of research that has found that sludge can be contaminated with human-made “forever chemicals” known as per- and polyfluoroalkyl substances, or PFAS, which are used in a wide range of household items such as nonstick cookware, waterproof clothing and stain-resistant carpets.

Chemicals found in sewage sludge that some farmers use to fertilize fields and pastures can pose a threat to human and animal health, the US Environmental Protection Agency said Tuesday.

Farmers who use sewage sludge as fertilizer and their neighbors face higher risks of cancer and other diseases, according to a new federal analysis that pins the blame on toxic forever chemicals. The findings are particularly relevant for northeast Illinois,

Levels of PFAS in sewage sludge used as fertilizer can pose risks that sometimes exceed safety thresholds “by several orders of magnitude,” the agency said.

The Environmental Protection Agency said “forever chemicals” in fertilizer made from sewage and spread across pasture endanger farmers and others who regularly consume beef, milk and other products fr
