Containment dome on well

A concrete-and-steel funnel has been placed over a blown-out oil well at the bottom of the Gulf of Mexico in a bid to contain oil leaking from it. BP said it might take up to 12 hours for the containment device to settle in place, but that everything appeared to be going as planned. It's hoped it will be able to collect as much as 85 percent of the oil and begin funneling it to ships above by Monday. (Source: BBC, 05/07/10) BP operated the Deepwater Horizon oil rig in the Gulf of Mexico which sank April 20 after an explosion that left 11 people missing and presumed dead. The underwater well has been spewing oil since then. The oil threatens to harm the sensitive beaches and marsh lands along the Gulf Coast. Some of the oil has washed ashore in Louisiana.
