Remediation of Poly- and Perfluoroalkyl Substances (PFAS) Contaminated Soils – To Mobilize or to Immobilize or to Degrade?

SYNOPSIS

• Immobilisation of PFAS in soil using amendments such as RemBind^®, organoclays and PAC is a viable treatment alternative.
• PFAS immobilisation using RemBind^® has been used at full commercial scale to treat 1,000’s of tonnes of soil in Europe.
• A case study involving the treatment of 1,000 tonnes of PFAS contaminated soil in Australia with full EPA sign-off is highlighted.
• Independent work by a Swedish research group showing that PFAS leachability in soil was reduced by 94% using RemBind_^® and by 70% using PAC.
