How about some benzene in your water? Yellowstone river gets Keystoned.

If anyone thinks this bituminous gunk is the same as the sweet crude being pulled from the ground elsewhere? I have some Tar Pits out here in Los Angeles you might be interested in buying...

They have to cut this sludge with a lot of benzene to make it flow through the pipeline. It isn't the pipeline that's such a bad thing. It's the route over the aquifer and the added chemical hazard of so much benzene flowing through it.
