The AP reports:
The Army has recovered 32 munitions from the ocean floor off the Waianae Coast this month during a project to clear away most of the weapons the military dumped there decades ago.
Of these 12 were treated to remove and destroy the explosive contents. But the not all munitions found are being removed:
It’s been difficult for the robot to remove the weapons as coral growth has basically cemented many to the ocean floor. The Army is leaving heavily coral encrusted munitions in place.
There are an estimated 2,000 weapons in the area nicknamed “Ordnance Reef.”
