Per- and Polyfluoroalkyl Substances (PFAS) in source area soil can create persistent groundwater plumes, which can be mitigated by soil removal or in situ treatment. Thermal desorption involves heating the soil to release PFAS chemicals, which are then removed using soil vapor extraction and treated aboveground. This process offers an onsite remediation alternative to offsite transport and treatment. This NAVFAC Fact Sheet on Thermal Desorption of PFAS from Soil summarizes two case studies from the Department of Defense (DoD) Environmental Security Technology Certification Program (ESTCP) demonstrating successful PFAS soil remediation using ex situ and in situ thermal treatment.
getting fluorine mass balance was a tough nut to crack
Awesome to see this important work shared, Russ, great job!

5dNice summary of the work done by Jacobs, Battelle, TRS, and others. Congratulations Amanda Struse on leading this effort!
