Coast Guard checks out dark-stained water in Chandeleur Sound, Times Picayune, March 24, 2011:
The Coast Guard began an investigation of a large area of dark-stained water in the Chandeleur Sound on Wednesday to determine whether it might be oil, even as the agency was overseeing a separate cleanup of oil near Grand Isle, to the west of the Mississippi River. ...
John Arenstam, the Coast Guard's New Orleans deputy sector commander, said Wednesday that his agency had received reports of oil-like material east of the river from officials with the state Department of Environmental Quality, who flew over Chandeleur Sound on Tuesday. ...
Meanwhile, the Coast Guard confirmed that it has notified Anglo-Suisse Offshore Partners that preliminary samples suggest oil samples collected from Elmer's Island, to the west of Grand Isle, match those from the company's West Delta 117 well...
But the Coast Guard has not determined that the company is the legal "responsible party."
"We do not believe the spill along the coast is the result of our operations, however, when the Coast Guard informed us that this might be the case, the responsible thing to do was mobilize," said Anglo-Suisse CEO John Sherwood in a news release issued by the Coast Guard.
Over the weekend, the Coast Guard reported test results of a third area of suspicious water stretching south from off Grand Isle, saying small quantities of oily substances were below the state DEQ's water standards.
