New rules that set Pennsylvania’s first-ever limits on so-called “forever chemicals” in drinking water will soon be enacted. The rules recently appeared in the Pennsylvania Bulletin, meaning they have taken the final step in a regulatory process that began five years ago. For years, environmentalists have urged regulators to crack down on PFAS chemicals, which are widely used and are deemed a health risk. They are currently unregulated at the federal level but Pennsylvania has been moving ahead with limits. The Pennsylvania Department of Environmental Protection says federal money may be available to help small communities comply with the rules, because the new mandates involve protecting public health.
