Abstract: Range clearance operations generally results in recovery and identification of a wide variety of munitions, both modern and obsolete. Estimates of munitions integrity can be based upon: (A.) firing range physical surveys, (B.) dud rates, (C.) low-order detonation rates, (D.) degree of corrosion, and (E.) number of cracked and broken shell casings. Determining the distribution and density of UXO on a firing range is a difficult exercise. Estimates of ordnance density and distribution obtained during the explosives safety exposure assessment are an important source of information for UXO source term modules. The Unexploded Ordnance Density Calculator appears to be an effective means for linking density and distribution estimates to the source term module for UXO fate and transport evaluation. Concentration of explosives can be determined by composite sampling and using field and refined laboratory analytical chemical methods. Detection of explosives residues at artillery and mortar ranges will require low-detection-limit laboratory methods. Sampling and analysis of explosive concentrations in firing range soils showed that concentrations were highest next to a munition that had undergone a low-order detonation during a disposal attempt. Concentrations of explosives were generally low in detonation craters and adjacent to intact munitions. These results suggest that explosives residues are likely to be low except when low-order or breached munitions are present.
