In Sweden a local village near an airbase has been struggling with the long term effects of the PFAS from the fire fighting foam used in exercises. Although the connection to the awful health outcomes seems established I don’t think they are getting compensation.

The equivalent in the US is Vint Hill Farms, Virginia. Cold War CIA base used as a listening post primarily, but also to test things like fire suppression and rumored to be a home of Agent Orange. It was an EPA Superfund site (aka so horribly polluted that they needed to do something about it) decided to do nothing and then build a ton of home on and around the heavily contaminated area. I don’t have data but anecdotally cancers here are insanely high in prevalence.
