One (short!) year ago today, BP’s Deepwater Horizon oil drilling rig exploded 42 miles off the coast of Louisiana. Eleven families lost loved ones on that day, but the social, economic, and environmental damage had only begun.

By April 22, 2010 the $560 million rig sunk, leaving oil spewing from the seabed into the Gulf of Mexico. On the 29th, the state of Louisiana declared a state of emergency due to the threat posed to natural resources, and U.S. President Barack Obama stated that BP was responsible for the cleanup.
Hopeful in those first days, remote underwater vehicles were sent to activate the blowout preventer, but the effort failed. In the following weeks that turned into months, controlled burns, booms, skimmers, and dispersants were used to cleanup oil as efforts to stop the oil flow were underway. The Justice Department launched a criminal and civil investigation, a moratorium on oil drilling was enacted and later rescinded, and the no-fishing zone grew to 37% of American Gulf waters. After 5 months, 8 days, and roughly 5 million barrels of spilled oil, a pressure test finally determined that a relief well had successfully stopped the oil flow. The spill was the world’s largest accidental release of oil into a marine environment.
