LOUISIANA (NBC33) — A sheen of oil that was spotted near the site of the Deepwater Horizon rig has been directly linked to the Macondo well, according to the U.S. Coast Guard.
"The exact source of the sheen is uncertain at this time but could be residual oil associated with wreckage and/or debris left on the seabed from the Deepwater Horizon incident in 2010," the agency said in a release Wednesday night.
The oil sheen was discovered on Sept. 16 after it was spotted on a satellite image from BP. A Coast Guard response team collected samples that were then processed by the Coast Guard Martine Safety Labe in Connecticut.
Officials say no adverse effects to the environment or marine life have been reported.
