Remediation of soils at Small Arms Firing Ranges (SAFRs) present unique challenges in that contaminants exist as both discrete particles and as sorbed compounds dispersed throughout the soil matrix. The form and distribution of particulate lead varies based on range use, size and impact velocity of the round, soil characteristics, and past range maintenance practices.

Removal of the discrete particles as part of remedial activities not only reduces the total lead, but also the leachable lead accordingly. Unfortunately, though, simple dry screening seldom, if ever, is suitable to remove these lead particles through all of the size ranges where it is present. The Internet training introduces the participants to the various physical (including hydraulic), chemical, and biochemical mechanisms available to treat or stabilize SAFRs after some unique characterization challenges are overcome. This training is based on the ITRC document entitled: “Technical & Regulatory Guidance Document for Small Arms Firing Range Remediation Technologies.”
