DuPont (the chemical company) has been dumping PFOA/C8 chemicals into various waterways, causing cancer and birth defects[0] across hundreds of towns and cities in various parts of the US for decades[1], and when the EPA told them to stop and fined them something like $17M (for a company that makes tens of billions of dollars a year), they promptly switched to a different chemical process to produce Teflon that resulted in identical health issues[2].

Did any of their executives see any criminal charges? Of course not.

The Devil we Know is a great documentary, by the way.
