Modeling of Groundwater Flow and Contaminant Transport at the Moab Site

In order to reduce contaminant mass in the groundwater system and to be protective of potential endangered fish habitat in backwater areas of the river, the model will be used to simulate the following remedial actions proposed by DOE: (i) Pumping contaminated groundwater from the shallow plume to an evaporation pond on top of the tailings pile, and (ii) Injecting the diverted Colorado River water into the alluvial aquifer. The numerical simulator SEAWAT is used to model variable density groundwater flow and transport at Moab site.
