That's a giant cloud of [vinyl chloride] and a ton of other bad chemicals. The local police blew it up like a beached whale, now megatoxins are Chernobyling Ohio and there's a news blackout and the police are beating reporters and camera people and dragging em. This environmental devastation will be visible from space for decades. The water is safe to drink but everything in it is suddenly dead. The next town over, the release instantly killed everyone's chickens. This stuff is catnip for human cancer.
