Field Demonstration of a Sieving and Stabilization Technology on Lead-Contaminated Soils at a Small Arms Range at Mayport Naval Air Station

摘要

One source of environmental heavy metal contamination is impact berms at smallarms ranges. Soils used to capture the bullets can accumulate lead in excess of the RCRA hazardous waste limits. This report describes a method to recover and recycle the lead bullets screened from the soil and to treat the soil to reduce the leachability of the remaining lead contamination. A field demonstration using a stabilization process based on a soluble silicate and cement formulation was conducted to evaluate the chemical effectiveness of this technology and the ability to reuse the stabilized soil to capture bullets in the unpact berm.
