Toxic PFAS "forever chemicals" that leach from landfills into groundwater are among the major pollution sources in the US, and remain a problem for which officials have yet to find an effective solution. The findings, which showed up to three times as much PFAS in landfill gas as in leachate, are "definitely an alarming thing for us to see," said Ashley Lin, a University of Florida researcher and the lead author of the study. As researchers have begun to understand the chemicals' dangers in recent years, the focus has largely been on water pollution, and regulators have said virtually all leachate from the nation's 200 landfills contain PFAS.
