PFAS – Containing The Problem
The presentation will focus on the PFAS Problem outlining Geofabrics research and findings regarding geosynthetics options for containment in landfill repositories. Geofabrics has undertaken long-term durability testing and along with academic research, assessed the chemistry of different types of PFAS found in landfill leachates tested. Geofabrics has evaluated current containment and treatment products and how they perform when in contact with PFAS. Consequent findings has lead to the development and introduction of an Australian made Geofabrics product, Sorbseal – a hybrid GCL AND PFAS attenuation layer for use in landfill storage and contaminated sites.
SORBSEAL® is a hybrid geosynthetic clay liner designed as a hydraulic barrier to liquid contaminants, using bentonite and powdered activated carbon to trap and seal dangerous chemicals away. SORBSEAL® lays at the base of, and over contaminated landfill sites like a blanket to stop it leaking out and contaminating the environment around it.
