Thermal Desorption of PFAS-Impacted Soil

Overview

Join us on February 20, 2025 at 12:30PM EST for a technical webinar regarding Thermal Desorption of PFAS-Impacted Soil.

Background/Objectives

Reducing the risk to per-and polyfluoroalkyl substances (PFAS) exposure, the environmental community has been focused on remediating groundwater; however, the majority of PFAS is sorbed to soil. Funded by the Department of Defense’s field implementation research program, TRS Group, Inc. (TRS) has completed three projects for the thermal desorption of PFAS-impacted soil. The presentation will cover the basics of thermal remediation and application of the technology for PFAS removal.

Approach/Activities

TRS applied thermal conduction heating at three sites (two ex situ soil piles and in situ soil at one site), volatilizing the PFAS, capturing the vapors, and concentrating the volatilized PFAS on activated carbon. Following two smaller pilot studies, the third involved heating a 2,000 cubic yard soil pile at Joint Base Elmendorf-Richardson in Anchorage, Alaska.

Results/Lessons Learned

The construction of an engineered soil pile allowed for the achievement of remedial objectives in significantly less time and with lower energy consumption than anticipated. All PFAS analytes were reduced to near or below detection limits. TRS has demonstrated that the thermal desorption of PFAS in soil is a viable remedial and commercially-available alternative.
