PFAS May Taint Nearly 20 Million Cropland Acres



The toxic “forever chemicals” known as PFAS could be contaminating nearly 20 million acres of U.S. cropland, according to an Environmental Working Group (EWG) estimate. Using state data, EWG estimates 5 percent of all crop fields could be using sewage sludge, or biosolids, as a fertilizer, even though it’s often contaminated with PFAS. Once PFAS-contaminated sludge is applied as a fertilizer, the chemicals can build up in food crops, feed crops such as corn and hay, and the animals that eat these feed crops. Several farmers have been forced to euthanize their farm animals due to high levels of PFAS in farm products. PFAS can cause a broad range of health harms to humans, as well. Very low doses in drinking water have been linked to suppression of the immune system and are associated with an elevated risk of cancer and reproductive and developmental harms. Tune in as we talk about this issue with Dr. David Andrews, Senior Scientist at the Environmental Working Group.
