Unknown substance leaking from Deepwater Horizon site

More than a month after BP and the Coast Guard finished a subsea operation to inspect the Deepwater Horizon site for oil leaks, no source has been found. Also, BP and the Coast Guard have not publicly identified a mystery white, milky substance observed seeping from the wreckage. But they say it's not oil and it's not harmful.

Recurring oil sheens have been spotted in recent months around the Deepwater Horizon site. Several missions to inspect the sunken Deepwater Horizon platform, riser pipe, wellhead, relief wells and containment domes found no oil leaks. However, the Coast Guard reported seeing "an unidentified substance inconsistent with oil" emitting from several areas of the wreckage. Samples were collected for analysis and the Coast Guard this week said the lab "detected no traces of harmful pollutants," and that a BP test "yielded similar results."

Neither BP nor the Coast Guard responded to the question of what the unidentified substance may be.
