Unexploded Ordnance (UXO)
Unexploded ordnance or UXO are potentially dangerous munitions of all sizes that remain buried in the earth. Even today there is a residual amount of UXO’s in the ground, despite clearance activities. For example, not less than 1.9 million tons of bombs and ammunition were dropped over Germany during World War II. 70 years later, thousands of UXO remain in the ground.
Where there is a UXO risk the requirement becomes finding the UXO through surveying and performing UXO clearance activities until the site is clear and it is approved for safe use.
