The U.S. Army is investigating incidents of unexploded World War I-era munitions showing up in clamshells used as paving material for driveways and parking areas in Delaware, Maryland and Virginia.
The ordnance was dredged up over the past 18 months from the ocean floor during mechanical clam harvesting operations off the New Jersey coast, in the vicinity of Atlantic City, according to Robert Williams of the U.S. Army Corps of Engineers, which is conducting the probe.
More than 300 munitions - mostly British and French-made hand grenades but at least one 75 mm projectile containing a chemical agent - have been recovered from 18 driveways and a Delaware clam-processing plant, Williams said.
Some grenades were actually found inside the clams.
Last February, a Bridgeville, Del., resident discovered 32 corroded - but live - hand grenades while spreading crushed clamshells delivered to his property. Subsequent similar discoveries triggered the investigation.
