Wastewater treatment plant testing reveals limited removal of organofluorines, putting millions at potential risk

A research team led by Harvard University has found elevated concentrations of organofluorine in U.S. municipal wastewater. More than 60% consisted of widely prescribed fluorinated pharmaceuticals, while 6 federally regulated perfluoroalkyl and polyfluoroalkyl substances (PFAS) made up less than 10% of total extractable organofluorine in samples.
