Map: Water Test Results for PFOA+PFOS and other PFCs
At least 6 million people have been drinking water with PFC concentrations that exceed the EPA's health advisory level, according to a study published in Environmental Science and Technology Letters.
This map includes PFC contamination in public water systems, as documented by the EPA, through 2015, and contamination in both private wells and public water systems as reported by community members and verified by public officials. Data includes systems with PFC contamination that falls below the EPA's health advisory level of 70 parts per trillion.
