In this lysimeter study we studied the impact of using biochars to reduce mobility of PFAS in soil. Over 100 years, nearly all PFOS are predicted to leach from no-sorbent lysimeters, while < 1 % will leach from soil treated with sewage sludge- derived biochar.

Measurement and modelling of sorbent-amendment impacts on seasonal and long-term PFAS transport through unsaturated soil lysimeters
This study investigated the effectiveness of waste-derived biochar amendments and commercial sorbents in stabilizing PFAS-spiked soils in field-scale …
