We learn about the contamination of military bases in the U.S. and Canada from PFAS chemicals in firefighting foam. And how the foam residue has poisoned drinking water sources in both countries. We hear about one community in Quebec that was faced with a big problem finding a new source of drinking water.

And a group of firefighters who decided to create a safe alternative to the foam. But because it is a gel instead of a foam, they ran into roadblocks getting it certified for firefighters to use.

The issue was a big one for a congressional committee looking into PFAS. It called the military, the Environmental Protection Agency and the companies making the PFAS chemicals to testify and explain their actions. The members of Congress were looking for clear answers and weren’t happy when they didn’t get them.
