The 2010 Deepwater Horizon Oil Spill is the worst oil spill in U.S. history. Within days of the April 20, 2010 explosion and sinking of the Deepwater Horizon oil rig in the Gulf of Mexico, underwater cameras revealed the BP pipe was leaking oil and gas on the ocean floor about 42 miles off the coast of Louisiana.
By the time the well was capped on July 15, 2010 (87 days later), an estimated 4.9 million barrels of oil had leaked into the ocean. Eleven people also lost their lives and the fire burned for 36 hours before the rig sank. To date, BP has probably spent more than $27 billion — including more than $14 billion on response and clean-up, and more than $13 billion on claims paid to individuals, businesses and government entities.
