Solidification/Stabilization to Manage PFAS in Soil & Landfill Leachate

This webinar explored the feasibility of using of solidification and stabilization to manage PFAS in soil, sewage sludge, and landfill leachate.

The webinar was presented for informational purposes. The views expressed do not necessarily reflect those of each of the NEWMOA-member states, and the strategies and technologies discussed should not be considered an endorsement by NEWMOA or its members.

The webinar included presentations from:

• Johnsie Lang, Arcadis [PDF] presented the results of a field demonstration of PFAS leachability following in-situ soil stabilization.
• Paul Ruehl, Holcim (US) [PDF] presented on the use of cement products for solidification/stabilization (S/S) of soil in-situ, and S/S of landfill leachate concentrate and the use of the treated leachate as alternative daily cover (ADC).
• Yanna Liang, University of Albany [PDF] presented a comparison of sorbents for stabilizing PFAS in soil and sewage sludge and innovative sorbents that have potential to outperform commercially available sorbents.
