Are there any environmental disasters in northeast Kansas?

I need to know of any environmental issues/problems in northeast Kansas. Not something like global warming, but something like a big industry dumping toxic waste in a river. Has anything like that happened recently? Or even in the history of Kansas?Are there any environmental disasters in northeast Kansas?Okay, I'm a geologist in Southern California, so I'm not familiar with the geography (not geology, geography) of Kansas, but you have a number of Federal Superfund sites, which qualify as the *most polluted* sites in the nation. Don't feel bad, every state has them. There's a list below (2nd link) with locations, and you can look to see if they're in the northeastern part of Kansas. The bottom link has LOTS of data, but because it has LOTS of data, it is very slow to load. But it's there, if you're patient. The third link is where you can find every Superfund site by state, if you're interested. The first link is just a simple explanation of what Superfund is.
