USCG: No Deepwater Horizon oil in gulf

More Oil? UPI

NEW ORLEANS, March 21 (UPI) -- A suspicious sheen on the water in the Gulf of Mexico is believed to contain sediment not oil from the Deepwater Horizon site, the U.S. Coast Guard announced.

The U.S. Coast Guard during the weekend responded to reports of possible oil pollution stretching into the Gulf of Mexico.

Analyzed samples from the suspected sheen contained trace amounts of petroleum hydrocarbons, oil and grease, the Coast Guard said. The dark substance is believed to be the result of an increase in sediment that was agitated by dredging operations in the Mississippi River.

Additionally, the Coast Guard said it received notifications of possible pollution in coastal areas along the Gulf of Mexico.
