Description
Geosynthetics and other polymeric materials are widely used throughout modern landfill infrastructure, including liner and cover systems, drainage applications, and leachate collection. As the waste industry works to better understand PFAS sources and movement, these materials represent another part of the system that warrants consideration.
This EREF report synthesizes available research on PFAS in geosynthetics, examining how PFAS may be introduced during manufacturing, the compounds and concentrations identified in tested materials, and what is currently known about their potential release and environmental behavior. The research finds measurable PFAS in tested geosynthetics while highlighting significant remaining uncertainties, particularly around long-term release under field conditions and the ability to distinguish geosynthetic-derived PFAS from other sources.
For landfill owners and operators, engineers, consultants, and environmental professionals, the report adds another piece to the broader PFAS picture and provides context for future decisions involving monitoring, source attribution, material selection, and infrastructure management.
