A recent oil spill, say environmentalists, could be a warning signing for the town of New Castle.
Work crews are cleaning up the last of a spill from Battery Park after a cargo ship dumped 100 gallons into the Delaware River.
The Wilmington News Journal reports that the oil came from the barge Wild Cosmos on March 9th at the Port of Wilmington.
The paper reports that tar balls have been discovered as far north as Salem County, New Jersey.
Around 15-hundred feet of shore at New Castle has already been affected.
