Rick Wawrzeniak fills a pot with water at his Salisbury, MD, home after filtering it to remove PFAS or "forever chemicals." Tucked within the Shenandoah Valley of Virginia, Joe Dinardo and his community rely on well water. After working with Rockbridge Conservation to test his water, the retired toxicologist found it contained "forever chemicals." To protect himself, he's been filtering his water for the last two years. Toxic forever chemicals, or per- and polyfluoroalkyl substances (PFAS), are prevalent in waterways across the Chesapeake Bay region. They were developed in the 1930s and have been used in a wide range of products for their stain-resistant and heat-resistant properties. There are more than 14,000 PFAS compounds, but they all have a strong carbon-fluorine bond that makes them nearly indestructible. Forever chemicals range in toxicity, but many have been linked to health issues such as cancer, developmental effects and cardiovascular problems. Two compounds, PFOA and PFOS, have been banned in the U.S. because they are possibly carcinogenic. Advocates in every Bay state are working to address these chemicals at a systemic scale. In the meantime, Samendra Sherchan, professor of environmental health sciences at Morgan State University in Maryland, said that reducing levels of...
