Grim Milestone

Obama's oil spill surpasses Exxon Valdez.

Even using the most conservative estimate, the new numbers mean the leak has grown to nearly 19 million gallons over the past five weeks. If the oil filled gallon milk jugs lined up side by side, there would be enough to reach from New York to Chicago and back.

In the worst case scenario, if 39 million gallons has spilled, the oil would fill enough jugs to stretch from the Louisiana marshes to Prince William Sound in Alaska. That's where the Exxon Valdez ran aground in 1989, spilling nearly 11 million gallons.
