U.S. EPA Proposes New LOWER PFAS Levels for National Primary Drinking Water Regulation 

U.S. EPA Proposes New LOWER PFAS Levels for National Primary Drinking Water Regulation  | Newtown News of Interest | Scoop.it

 The U.S. Environmental Protection Agency (EPA) announced a proposed National Primary Drinking Water Regulation to protect public health from PFAS pollution. Polyfluoroalkyl substances (PFAS) are human-made chemicals that do not occur naturally in the environment and can cause adverse developmental and immune system effects.  

The proposed EPA regulation would establish legally enforceable levels, called maximum contaminant levels (MCLs), along with health-based, non-enforceable maximum contaminant-level goals (MCLGs) for six PFAS in drinking water:


The proposed rule notably establishes limits for more compounds and has more stringent levels than those adopted by the Pennsylvania Environmental Quality Board earlier this year. The commonwealth set MCLGs for PFOA at 8 ng/L and PFOS at 14 ng/L and MCLs for PFOA at 14 ng/L and PFOS at 18 ng/L. These levels were adopted to protect the health of commonwealth residents while the U.S. EPA continues to address rulemaking.  

[The new US EPA "enforceable" limits for PFOA and PFOS is 4.0 parts per trillion. Practically EVERY Newtown Artesian Water Company well has levels ABOVE these amounts. See chart.]
