Researchers: Synthetic Chemicals in Soils are “Ticking Time Bomb”

A growing health crisis fueled by synthetic chemicals known as per- and polyfluoroalkyl substances, or PFAS, in groundwater has garnered much attention in the last few years. The reported levels could be “just the tip of the iceberg,” as most of the chemicals are still migrating down slowly through the soil, according to Bo Guo, University of Arizona assistant professor of hydrology and atmospheric sciences. Nearly 3,000 synthetic chemicals belong to the PFAS class. They have been used since the 1940s in food packaging, water-resistant fabrics, non-stick products, pizza boxes, paints, firefighting foams and more, according to the Environmental Protection Agency. The chemicals don’t break down in the environment, nor in the body, and a growing number of research papers have shown that PFAS contamination in water sources is widespread in the United States and that exposure is harmful to health.  Read more....
