On September 18, just under 5 months since the Deepwater Horizon exploded on April 20, 2010, the oil spill in the Gulf of Mexico has been stopped. A cement plug was used to seal off the well, and formal Coast Guard Admiral Thad W. Allen has declared the well “effectively dead.” and no additional oil leaks have been detected.
No oil has leaked out of the well since a temporary cap was put on it in July. The cement plug is a more permanent solution. Between April and July, nearly 5 million barrels of oil gushed into the Gulf of Mexico. Crews have been working to clean up as much as they can, but there is still a lot of oil from the spill in the Gulf.
