Experts concerned well still leaking
An oil slick three miles long and three football fields wide that was discovered in the Gulf of Mexico last month has been traced back to the BP Deepwater Horizon oil disaster of 2010, the Coast Guard said Wednesday night.

BP and Coast Guard officials said the slick could be residual oil from the Deepwater Horizon wreckage; oil debris left on the seabed from the original spill; or oil emanating from bent piping still on the sea floor.
However, Ian MacDonald, a professor of oceanography at Florida State University and a spill expert, said that the presence of the slick could mean that oil is till leaking from BP’s Macondo well, the site of the blowout. “The jury is out here,” he said, adding that it was too early “to rule out that this is oil freshly released from the reservoir.
“No one’s 100 percent as to where it’s coming from,” said Frank Csulak, scientific support coordinator for the National Oceanic and Atmospheric Administration.
As of Wednesday, there was no plan of action for determining the immediate source. The Coast Guard told the involved companies, BP and Transocean, to come up with a plan but added that the slick “does not pose a risk to the shoreline.”
