"At least 45% of the nation's tap water could be contaminated with at least one form of PFAS known as "forever chemicals," according to a newly released study by the U.S. Geological Survey.
The man-made chemicals — of which there are thousands — are found in all sorts of places, from nonstick cookware to stain-resistant carpets to contaminated sources of food and water. They break down very slowly, building up in people, animals and the environment over time.
Research has linked exposure to certain PFAS to adverse health effects in humans, from an increased risk of certain cancers, increased obesity and high cholesterol risk, decreased fertility and developmental effects like low birth weight in children.
"This USGS study can help members of the public to understand their risk of exposure and inform policy and management decisions regarding testing and treatment options for drinking water," Kelly Smalling, a USGS research chemist who is the lead author of the new study released Wednesday, told NPR over email.
This study is the first to compare PFAS in tap water from both public and private supplies on a broad scale, throughout the country, Smalling said."
