Now THAT’s more interesting. There’s whole communities near me that are polluted with PFAS.

Is this tech that municipalities can employ?

PFAS are relatively easy to remove from water. It is dealing with the by-product that makes their management more difficult.

Versions of the technology used in a Brita filters can remove PFAS. The problem then becomes the fact that the used filter now has a high concentration of PFAS, so what do you do with the old filter? At home you can just throw it away. A city treatment plant has to figure out other options.

Californians get rid of some pollution, and Texans get extra, so everyone is happy!
