The US Environmental Protection Agency has set legally enforceable drinking water limits for a group of the most dangerous PFAS compounds, marking what public health advocates hailed as “historic” rules that will dramatically improve the safety of the nation’s water.
PFAS, known as “forever chemicals”, are ubiquitous in the environment and thought to be contaminating drinking water for more than 200 million people across the US. Any exposure to some highly toxic varieties of the compounds is considered a health and cancer risk.
