The Gulf of Mexico oil spill,is a massive oil spill in the Gulf of Mexico that is the largest offshore spill in U.S. history. By late June or early July 2010, some estimates placed it among the largest oil spills in history with hundreds of millions of gallons spilled to date.

The Gulf of Mexico oil spill stems from a sea-floor oil gusher that resulted from the April 20, 2010 Deepwater Horizon drilling rig explosion. The explosion killed 11 platform workers and injured 17 others. On July 15, 2010, BP said the leak had been stopped by capping the gushing oil wellhead,though there is a risk that a significant pressure shift could create a new leak on the sea floor. The drilling of relief wells to permanently close the well is ongoing.

The gusher was estimated by the quasi-official Flow Rate Technical Group to be flowing at 35,000 to 60,000 barrels of crude oil per day. For comparison, this is an amount equal to the 1989 Exxon Valdez oil spill every four to seven days. The exact flow rate is uncertain due to the difficulty of installing measurement devices at that depth and is a matter of ongoing debate. The resulting oil slick covers at least 2,500 square miles (6,500 km2), (the size of the state of Kentucky) fluctuating from day to day depending on weather conditions. Scientists have also reported immense underwater plumes of oil not visible at the surface.

The Gulf of Mexico oil spill continues to cause extensive damage to marine and wildlife habitats as well as the Gulf’s fishing and tourism industries. There have been a variety of efforts to stem the flow at the wellhead. Crews have been working to protect hundreds of miles of beaches, wetlands and estuaries along the northern Gulf coast, using skimmer ships, floating containment booms, anchored barriers, and sand-filled barricades along shorelines. The U.S. Government has named BP as the responsible party, and officials have committed to hold the company accountable for all cleanup costs and other damage.

Local and national economies will be effected by The Gulf of Mexico oil spill for many years to come.
