First of all, there's a difference between localized wind, and wind currents. Wind currents always follow the same pattern and hardly, if ever change. The only time they ever change is with large cyclical events, like El Nino. So even if the wind changes in your localized area, the overall wind drift is still going to push it in a specific, and predictable direction.
Second of all, I never claimed to be an expert on literally anything here. So I won't comment on anything I don't know about.
Thirdly, of course if you live in any of the effected areas you should have your water tasted, that's common sense.
EDIT: Accidentally hit save before I was done.
Fourthly From my understanding all the chemicals that were dumped, have a boiling temperature of at least 82 degrees Fahrenheit. And there's not a single body of water in North America that gets that hot, even in the summer. So none of this will evaporate with the water.
Fifthly, I'll give you a comparison. You say this stuff is toxic at 1 ppm (parts per million), so anyone who even touches the water or soil is a walking hazmat. Yet, for decades nearly every major river and lake in the USA has had an abundance of mercury contamination. Mercury is toxic at 2 ppb (parts per billion). So it's even more toxic, and there's more of it in the water. Yet, you never hear of anyone being a walking hazmat after walking through a contaminated river, or swimming in a contaminated lake, etc.
As for the rest of the points, well as I said, I'm not expert, so I won't comment since I have literally no idea, and I'd rather not comment on something I have literally zero knowledge over.
But overall, I maintain that while this is an environmental disaster, it's less of an end of the world scenario, and more chemical land based version of the BP oil spill.
Still horrible and someone needs to pay for it, but not a doomsday scenario.
