Repost @grist and @applenews:
“Today, the Environmental Protection Agency announced the nation’s first drinking-water standards for six types of per- and polyfluoroalkyl substances, known as PFAS. These long-lasting synthetic chemicals don’t break down naturally in the environment and have been linked to cancer, heart and liver problems, developmental damage, and other health issues.
Under the new rule, drinking-water concentrations of two of the most thoroughly studied and prevalent of these substances — PFOA and PFOS — will be capped at the lowest limit that the EPA believes is technologically possible, about four parts per trillion, reflecting scientists’ understanding that there is no safe exposure level for them. Three other common PFAS will be limited to 10 parts per trillion, either measured on their own, in combination with each other, or with one otherwise-unregulated chemical.
While the compounds being regulated represent a fraction of the entire class of chemicals — more than 15,000 distinct variants fall under the PFAS umbrella — the EPA estimates that its new rules will protect some 100 million people from exposure and prevent tens of thousands of serious illnesses, especially cancers.
“We are one huge step closer to shutting off the tap for forever chemicals once and for all,” agency head Michael Regan said.”
