Description
Summary:The testing, evaluation, and sensitivity analysis of an in-situ groundwater bioremediation model is presented. BI02D is a two-dimensional, areal finite element model that incorporates oxygen limited Monod kinetics. It is validated using the International Groundwater Modeling Center's Level 1 Testing Protocol for its ability to model flow and transport of a conservative pollutant. Level 2 Testing is done for four hypothetical cases involving the cleanup of a phenol-contaminated aquifer. Predicted phenol concentrations are shown to be very close and slightly greater than solutions from the better known and tested model BIOPLUME II. It is shown that BI02D outperformed BIOPLUME II in the final test, which involved an injection-extraction well doublet, due to greater mass balance errors and numerical dispersion in BIO-PLUME II. Two potential improvements to BI02D are presented.
