Independent studies by two government entities have concluded that, to date, the spill is between 17 and 39 million gallons, making this the worst spill in US history. The calculations were made by using two different methods. By comparison, the Exxon Valdez spilled 11 million gallons. The Ixtoc I platform, which burned and sank in 1979 off the coast of Mexico, spilled approximately 126 million gallons.
