In brief
Research from 3M dating back to 2003 indicated the presence of harmful "forever chemicals" in sewage sludge used as fertilizer, yet the E.P.A. continues to endorse its application on farms, raising serious environmental and health concerns.
In a startling revelation, the Environmental Protection Agency (E.P.A.) has been promoting the use of sewage sludge as fertilizer, despite having been informed by 3M about the associated toxic risks nearly two decades ago. In early 2000, scientists at 3M discovered concerning levels of per-and polyfluoroalkyl substances (PFAS), infamous for their persistence in the environment and possible link to serious health issues, in sewage across the United States. Alarmingly, these toxic substances were being spread on farmland nationwide under the endorsement of the E.P.A.The 2003 information shared by 3M, though not publicly disclosed, indicated growing concerns regarding the hazards posed by PFAS exposure. These chemicals, often dubbed "forever chemicals," are linked to adverse health effects including birth defects and cancer. Despite the significant findings, the E.P.A. has not mandated testing for PFAS in sewage sludge used for agricultural purposes, even as evidence mounts over the years from multiple sources—including whistle-blowers, researchers, and state officials—indicating contamination issues.Former E.P.A. microbiologist David Lewis underscored the complexity of the toxic mixtures in sludge, highlighting that once contaminated, soil becomes nearly permanently affected. This ongoing endorsement by the E.P.A. raises urgent questions about the agency's commitment to public health and safety, as experts warn of the long-term implications for both the environment and human health inherent in the utilization of treated sewage for agricultural practices.
