Remediation of Lead-Contaminated Soils at Small Arms Ranges

The objectives of this study were to assess the level of lead contamination at the US Navy`s small arms ranges, to determine the potential for non-point source pollution, and to select and apply a remediation technology suitable to such sites. A combination of screening and stabilization were selected as the best remedy following bench-scale and field-pilot testing. Binders tested at bench scale included cement, cement-silicate, and lime-fly ash. Optimum treatment was achieved with either cement or a combination of cement and silicate.
