Hydrothermal Technologies for On-Site Destruction of Site Investigation Wastes Contaminated with Per-and Polyfluoroalkyl Substances (PFASs)

Abstract

This SERDP limited scope project evaluated the effectiveness of applying nascent hydrothermal conversion technologies to destroy PFASs and co-contaminants present in liquid and soil wastes. Specifically, the research identified reaction conditions (e.g., temperature, time) and low-cost amendments that promote rapid degradation and defluorination of per- and polyfluoroalkyl substances (PFASs) associated with aqueous film-forming foam (AFFF), assessed the reaction kinetics and mechanisms, and applied the process to treat PFAS-contaminated water and soil samples, including investigation-derive waste (IDW). Results demonstrate that hydrothermal treatment can be an effective alternative to off-site incineration.
