The roar of heavy bulldozers and massive conveyor belts joined the crack of gunfire at the site of what may be the busiest small arms range in the world, Rodmans Neck, NY. MARCOR had the job of removing millions of spent rounds fired by police officers at the 54-acre range. Embedded lead bullet fragments were so concentrated, that new bullets were ricocheting off firing range berms. MARCOR crews literally worked "under the gun."
A combination of physical and chemical processes were utilized to remove bullet fragments, treat the soil, and restore the site. Soil was subject to strict quality control. More than 320 tons of lead were recycled after being separated via MARCOR's exclusive Pneumatic Separation Unit (PSU). ACT (Advanced Chemical Treatment) was employed to achieve full remediation.
After treatment,the soil was returned to the range and the berms rebuilt. It was critical that the soil retain the proper consistency to allow for growth of erosion-controlling vegetation.
Similar processes may be adapted to sites exhibiting many types of heavy metal contamination.
