A fly ash retention pond at a Tennessee coal-fired steam plant
failed, spreading 2.6 million cubic yards of the stuff over about 400
acres of the surrounding landscape.

No doubt the company media folks will spin this as just a big mess;
but the fact is there's a good deal of heavy metals & other bad ****
in that stuff.

I know its a comfortable distance west of the good streams in western
NC; but what's the overall impact going to be on local streams in that
area?

Does that fly ash really contain much in the way of heavy metals? Coal is
carboniferous I would have thought not so very much aluminium, Iron
compounds , Calcium oxides and silicates seem to be the most common
constituents pretty much like cement which is a secondary use hopefully it
won't impact too much but an alkaline flush has to be a possibility thats
not going to be good unless it can be contained.
