Police and firefighters cordoned off a section of Fort Meade on Wednesday morning after utility workers discovered a piece of unexploded ordnance from the World War II era, base officials said.
The workers were doing scheduled maintenance work in a residential section of the Army installation in Anne Arundel County around 10:30 a.m. when they found the mortar training round, officials said.
The Fort Meade Department of Emergency Services cordoned off a 300-meter area near 2nd Army Drive and Potomac Place, officials said. As many as 20 homes were affected, but only six were occupied.
An explosive ordnance detachment determined the round was inert and removed it, officials said. Residents were allowed to return to their homes at about 12:30 p.m.
Officials said utility and construction workers on Fort Meade are made aware of the potential to encounter unexploded ordnance and are trained in the proper procedures to report the devices.
