Permeation of Per-and Polyfluoroalkyl Substances (PFAS)-Laden Leachate in Landfills as an Outcome of Puncture Failures of High-Density Polyethylene Geomembranes
Science
12 Nov 2024 | Environmental Pollution
Puncture failures in high-density polyethylene landfill liners increase the permeation of hazardous PFAS-laden leachate. Short-chain PFAS, due to their surfactant properties, significantly enhanced permeation rates, highlighting concerns over environmental contamination if proper landfill protections are not maintained.
