On Wednesday, the Environmental Protection Agency released newly-acquired data showing that over 143 million Americans are exposed to so-called “forever chemicals,” or PFAS. The source of this exposure is their drinking water — and as more data comes in, that number is expected to rise.
In the analysis, the EPA learned that 11 million more people are exposed to PFAS (per- and polyfluoroalkyl substances) in their drinking water than was previously reported. The EPA performs an annual set of studies known as the Unregulated Contaminant Monitoring Rule, of which this was the fifth iteration. The UCMR mandates that water utilities across the U.S. test drinking water for 29 different PFAS compounds. PFAS are linked to health problems like high blood pressure, liver disease, lowered sperm count, and various cancers.
