Efficiency assessment of PFAS immobilisation for large volumes of diffuse contaminated soil at airports.

This study evaluated the feasibility of immobilising diffuse per- and poly-fluoroalkyl substance (PFAS) contaminated soil by developing and validating a novel field-scale methodology. The effectiveness of this approach was assessed via a field-scale trial conducted at an airport in Australia. Prior to full-scale treatment, laboratory trials were undertaken to determine optimal treatment reagents and application rates.
