Objectives

1)To determine the fate and transport behaviour of PFAS in diverse natural unsaturated soils with and without sorbent amendments, 2) To integrate ex-situ thermal pyrolysis options to simultaneously degrade PFAS substances vis heat and convert organic matter into a PFAS sorbent, 3) To optimize approaches for using soil washing and sorbent amendments for in situ remediation of PFAS contaminated soils.

Planned secondment(s):

SLU (M21, 6w; M33 5w) for training and analysis of PFASs;

HSF (M25, 3w) for looking at PFAS residues after thermal pyrolysis.

1-day visits to a local wastewater treatment facility (Oslo Airport Gardermoen, OSL) (M12 after ATC3) as well as UFZ (after ATC6 in M24).
