AFFF Stockpiles
Disposal of concentrated AFFF is a challenge due to mounting technical and regulatory concerns. Historically, AFFF concentrates have been incinerated, but recently the DoD released a temporary moratorium on the incineration of AFFF.
We recently partnered with an AFB to treat AFFF concentrates. For the full range of PFAS measured, >99.99% of PFAS was destroyed.

Fire Training Pond
AFFF used for fire training accumulates in pit water on-site. This results in high concentrations of PFAS, large treatment volumes, and other water quality parameters impacting treatment.
We recently partnered with an airport to conduct a continuous pilot study for treating fire training pit water. For the full range of PFAS measured, >99.91% of PFAS was destroyed.

Landfill Leachate and Soil
We recently treated both raw leachate and a foam fractionate from in-situ soil treatment.
For the full range of PFAS measured, >99.8% of PFAS was destroyed in the raw leachate and >98.9% was destroyed in the fractionate.
