Design and development of cost efficient remediation alternatives, modeling of nutrient and pollutant fate transport in ground and surface water.
ARC has developed a density-dependent model of groundwater flow to assess effects of brine on subsurface water movement and associated transport of contaminants released from legacy tailings pile.
The model provides analysis of challenging scenarios to simulate proposed DOE remedial actions to reduce contaminant mass in GW and protect endangered fish habitat in backwater areas of the river, including:
- Pumping contaminated groundwater from the shallow plume to an evaporation pond on top of the tailings pile.
- Injecting the diverted Colorado River water into the alluvial aquifer.
