Briefly: California proposes ultra-low “forever chemical” standards

According to CAL MATTERS, California recently proposed a new health limit on two “forever chemicals.” Proposed targets are 0.007 nanograms per liter of water for perfluorooctanoic acid (PFOA) and 1 nanogram for perfluorooctane sulfonate (PFOS), more than 70 times smaller than current federal guidlelines. One nanogram per liter is equivalent to a part per trillion. California previously created thresholds of 10 parts per trillion for PFOA and 40 parts per trillion for PFOS. The goal of the new health limits is to protect residents from the risks, including cancer, of drinking groundwater contaminated by these chemicals, used to make Teflon and Scotchguard. California officials plan to spend a year seeking public comment and additional review for the new health limits as they prepare to establish enforceable standards.
