State environmental officials say workers are still trying to clean up the site where a train carrying crude oil derailed and burned in west Alabama last month.
A spokesman for the Alabama Department of Environmental Management, Jerome Hand, says the cleanup is continuing nearly two months after the crash on a rural stretch of track near Aliceville.
Hand says officials have yet to determine how much oil was spilled into nearby wetlands.
A train of 90 tanker cars carrying crude oil derailed near Aliceville on Nov. 8, catching fire and spilling crude oil.
The area is near wetlands and a creek that flows into the Tombigbee River.
The train was carrying some 2.7 million gallons of crude based on railroad figures, but an unknown amount burned.
