The Training Range Environmental Evaluation and Characterization System TREECS was applied to a groundwater site and a surface water site to evaluate the sensitivity of the uncertain input properties degradation rates and water-to-soil and water-to-sediment adsorption partitioning distribution coefficients, or Kd values on the fate of three emerging constituents EC DNAN, NTO, and NQ. These three EC are components of the new insensitive munitions explosive formulation IMX-101. The authors reviewed the literature and provided estimates of the expected degradation rates and Kd values for the three EC. EC simulations were conducted for each site, and predicted concentrations in receiving groundwater and surface water were studied to draw conclusions regarding the sensitivity of the results to these uncertain inputs.
