Modeling groundwater flow for the Twin Cities Army Ammunition Plant site and vicinity
Argonne National Laboratory has modeled the groundwater flow in the area of the Twin Cities Army Ammunition Plant (TCAAP) with the Coupled Fluid, Energy and Solute Transport (CFEST) computer code. Argonne performed the modeling for the US Army in support of a remedial action program to capture and treat groundwater contaminated by past activities at TCAAP. This report presents the results of model development and calibration, in which various parameter values were tested to obtain the best match between model-predicted and observed groundwater elevations. After calibration, the model was used to evaluate the efficacy of the extraction well system used to pump contaminated groundwater to an on-site treatment plant. Argonne found that the wells effectively capture contaminants in the Hillside Sand (Unit 3) aquifer but not in the Prairie du Chien/Jordan (Unit 4) aquifer. 17 refs., 23 figs.
