Summary: Per- and polyfluoroalkyl substances (PFASs) are a group of environmentally persistent, man-made chemicals found likely to be carcinogenic in humans by the USEPA Science Advisory Board. Due to their non-stick, water and stain repellences, PFASs have long been used in everyday products (food wrappers, carpets, furniture etc) which end up in landfills. As it is currently unknown how PFASs move through landfill barriers, PFAS contamination has become a priority for the regulators of Australia’s landfill sites according to the Australian 2018 PFAS National Environmental Management Plan. This research will determine PFAS transport through common clay barriers enhanced with proteins which have been shown to be an excellent sorbent for PFAS.
