2010: In volume, BP's Deepwater Horizon oil spill overtakes Ixtoc I, which leaked 130 million gallons off Mexico's coast from 1979 to 1980, to become the worst oceanic oil spill in U.S. recorded history. Before it was capped on July 15, 2010, the Deepwater Horizon oil spill discharged 210 million gallons of oil, making it the largest accidental marine oil spill in the history of the petroleum industry.
