The objectives of this technology demonstration are to assess the environmental benefits, feasibility, and cost of using sand as a deceleration medium in small arms firing range SAFR berms in conjunction with amendments designed to retard the migration of lead Pb into the surrounding environment. The amendments provide for reduction of Pb solubility through potential hydrogen pH buffering of pore fluids within the SAFR berm, as well as the sequestration of Pb through surface adsorption and the precipitation of insoluble Pb salts. This technology application is known as a Passive Reactive Berm PRBerm . The purpose of the technology demonstration is to provide range operators with an economical means of controlling the off-site migration of Pb, while maintaining the benefits of sand as a deceleration medium. The PRBerm technology is applicable to new and existing ranges. In particular, this technology is designed to address sites where the native soils available for SAFR berm construction either lack the characteristics necessary to retard the migration of soluble Pb e.g., acidic soils or are susceptible to erosion and off-site transport of Pb as a result of their high clay content.
