Design of landfill cells to contain PFAS

The global discussion surrounding per- and polyfluoroalkyl substances (PFAS) continues to intensify. At the same time, a clear trend is emerging in the management of PFAS-contaminated soils: large volumes are being disposed of in landfills. In Australia, for example, approximately 88% of these soils are placed in landfill facilities.

Engineered landfills provide the technical infrastructure required to contain PFAS at a reasonable economic cost and within regulatory frameworks. However, safe long-term containment depends heavily on the design of the landfill cells. Key aspects include reliable liner systems, effective leachate management and the implementation of durable geotechnical barriers.

This raises a critical question: which technical approaches are required to reliably contain PFAS for decades or even centuries?

Our free whitepaper “Design of landfill cells to contain PFAS” addresses this very question and outlines the solutions that are essential for the safe disposal of PFAS-contaminated soils.
