Evaluation of per- and polyfluoroalkyl substances (PFAS) in landfill liquids from Pennsylvania, Colorado, and Wisconsin
Science
19 Mar 2024 | Chemosphere
Average PFAS levels in landfills from Pennsylvania, Colorado, and Wisconsin were 6,900, 22,000, 280, and 260 ppt in leachate, gas condensate, stormwater, and groundwater, respectively, with variations attributed to landfill design and local climate and higher PFAS levels in leachate exposed to open air and in groundwater near landfills without bottom liners.
