PENSACOLA, Fla. – Oil washed up along parts of a five-mile stretch of a beach on Florida's Perdido Key on Saturday, less than two weeks after Hurricane Sally made landfall in the area.


U.S. Coast Guard Petty Officer Dustin Williams told the Pensacola News Journal, part of the USA TODAY Network, the oil was discovered Saturday, and samples were collected to determine the source of the oil. The Coast Guard investigates reports of oil pollution in U.S. waters.


It's unclear at this point if the submerged oil is from the 2010 oil spill that was stirred up from Hurricane Sally or if it is from another source.

Williams said the Coast Guard will work with the Gulf Islands National Seashore to ensure the pollution is cleaned up.


"We want to get it cleaned up as fast as possible, so we'll be working with the Park Service to make sure that happens," Williams said. "Until we get those test samples back, right now, it's still an unknown source."


Williams said it unknown at this point how much oil washed up but said the estimated shore-line impact was about five miles.


Escambia County Administrator Janice Gilley said the oil looked like tarballs, perhaps from the 2010 Deepwater Horizon oil spill were washed up and liquified in the sun.
