| dc.description.abstract | Abstract: The Training Range Environmental Evaluation and Characterization System (TREECS) is being developed for the Army. This system has varying levels of capability to forecast the fate and risk of munitions constituents (MC) (such as high explosives (HE)), within and transported from firing/training ranges to surface water and groundwater. The overall objective is to provide Army environmental specialists with tools to assess the potential for MC migration into surface water and groundwater systems and to assess range management strategies to protect human and environmental health. Tier 2 will consist of time-varying contaminant fate/transport models for soil, vadose zone, groundwater, and surface water to forecast MC export from ranges and resulting concentrations in receiving waters. Model results can be used to assess the potential for surface water and/or groundwater MC concentrations to exceed protective health benchmarks at receptor locations of interest. The Tier 2 models do not make the highly conservative assumptions of steady-state (time-invariant) conditions and no MC loss or degradation was used for Tier 1. Thus, media concentrations computed with Tier 2 should be closer to those expected under actual conditions. Media concentrations will also reflect time phasing associated with time-varying MC loading conditions and transport arrival times, which can be greatly extended for the vadose zone and groundwater. Having time as a dimension in the analysis provides a powerful tool for examining range management strategies to promote attenuation of media concentrations. The information provided in this report is sufficient to serve as design specifications for the development of models and software that will comprise Tier 2 of TREECS. The details of the Tier 2 soil model formulations provided herein can also help serve as documentation for that model. All components will be packaged within a user-friendly PC client-based application with an emphasis on ease-of-use. | - |
