Estimates for the amount of thick sludge that gushed from a Tennessee coal plant this week have tripled to more than a billion gallons, as cleanup crews try to remove the goop from homes and railroads and halt its oozing into an adjacent river.

TVA's initial estimate for the spill was 1.8 million cubic yards or more than 360 million gallons of sludge. By Friday, the estimate reached 5.4 million cubic yards or more than 1 billion gallons -- enough to fill 1,660 Olympic-size swimming pools.

on a tributary of the Tennessee River called the Clinch River. At least 300 acres of land has been coated by the sludge -- a bigger area than the Exxon Valdez oil spill.
