Unsafe Levels of Teflon Chemicals In 6 Million Americans' Drinking Water

"Drinking water supplies serving more than six million Americans contain unsafe levels of a widely used class of industrial chemicals linked to potentially serious health problems, according to a new study from Harvard University researchers.

The chemicals — known as polyfluoroalkyl and perfluoroalkyl substances, or PFASs — have been used for decades in a range of industrial and commercial products, including non-stick coatings on pans, food wrappers, water-repellent clothing and firefighting foam. Long-term exposure has been linked to increased risks of kidney cancer, thyroid problems, high cholesterol and hormone disruption, among other issues.

“Virtually all Americans are exposed to these compounds,” said Xindi Hu, the study’s lead author. “They never break down. Once they are released into the environment, they are there.”"
