Abstract

A UXO model has been developed to estimate the source quantity of UXO for use as a source term model within the Army Risk Assessment Modeling System (ARAMS). ARAMS is based on the widely accepted risk paradigm, where exposure and effects assessments are integrated to characterize risk. ARAMS allows the UXO model to be readily used as a component in human and/or ecological health risk characterizations for estimating the mass of explosives that is needed as information to drive media fate/transport models, such as leaching through the vadose zone and runoff into surface waters. Calculated temporal media concentrations are then used within ARAMS to compute exposure and assess effects, both current and future. The UXO model provides an estimate of the source quantity of UXO using data from firing range records and other sourc
