PFAS Remediation Services

PerfluorAd is used for PFAS remediation at a fire station in Connecticut.

TRS offers PFAS remediation services for impacted soil and water that substantially reduce your treatment costs. Our FlexHeater® thermal conduction heating (TCH) service removes up to 99.998% of per- and polyfluoroalkyl substances (PFAS) from soil, eliminating the need to landfill or incinerate large volumes of soil.

Developed by Cornelsen GmbH, TRS Group’s partner in Essen, Germany, the PerfluorAdTM technology removes PFAS from water, extending the life of your activated carbon or resin beds. This service is also ideal for cleaning out aqueous film forming foam (AFFF) fire suppression systems, allowing their continued use. See more information at

Thermal Desorption of PFAS-impacted Soils

Awarded a patent in June 2020 by the U.S. Patent and Trademark Office, TRS provides in situ and ex situ heating solutions for PFAS remediation. We apply our FlexHeater® thermal conduction heating (TCH) technology to generate soil temperatures between 300-400 degrees Celsius, volatilizing and capturing the PFAS vapors for subsequent surface treatment. Concentration reductions typically exceed 99.998%.
