Broad Agency Announcement for Innovative Environmental Technologies and Methodologies

The project objective is to evaluate the feasibility of ex-situ stabilization and/or solidification for treating PFAS impacted soil and sediment. Specific goals of this project are to Evaluate multiple commercially available reagents for the solidification or stabilization of PFAS, Quantify PFAS kinetic leaching flux and mechanisms for stabilization and/or solidification treated soil/sediment, Develop a conceptual site model (CSM) to assess stabilization and/or solidification for reducing PFAS leaching and evaluate the extent to which recent bench-scale studies reflect stabilization and/or solidification treatment performance under actual field conditions and Collect sufficient performance and cost data to develop guidance on site-specific PFAS stabilization and/or solidification to treat soil/sediment compared to alternative methods (e.g., landfilling at the hazardous waste landfill or incineration) for remedy decision-making.The project objective is to evaluate the feasibility of ex-situ stabilization and/or solidification for treating PFAS impacted soil and sediment.
