Promising method to stop PFAS leakage at fire drill sites

PFAS can be found, among other things, in firefighting foam and many fire drills have become heavily contaminated. The Swedish Chemicals Inspectorate regards PFAS substances as hazardous to health and the substances spread quickly if they come into contact with groundwater.

- There are thousands of places where fire foam has been used that may contain PFAS, says hydrogeologist Robert Earon at the Norwegian Geotechnical Institute, SGI, which is behind the new research.

Promising method

SGI's research has been commissioned by the government and carried out at fire drills at Sundsvall and Örnsköldsvik airports. There, activated carbon has been used in the soil and the method is described as both promising and relatively simple.
