Containing the Gulf oil spill




Oil containment booms are seen staged at the edge of Lake Pontchartrain near the Rigolets on May 2, 2010 in New Orleans, Louisiana. Oil booms are being prepared at the edge of the lake to contain the approaching oil spill from the Deepwater Horizon wellhead which is still leaking an estimated 1,000 to 5,000 barrels of oil a day.
