The objective of this proposed research investigation has been to develop an accurate, robust, and cost-effective three-dimensional numerical model for the simulation of groundwater contaminant and mitigation techniques. A two dimensional test version of the model based on an operator splitting formulation has been completed. This prototype model divides the problem into the solution of the pressure field using a finite element based model and a solution for transported species using a finite difference approach. It is anticipated that this approach to the numerical solution will result in significant improvements in model accuracy and parallel computational efficiency. A three-dimensional colorgraphics package has been developed to allow visualization of complex flow fields. Finally, aquifer contamination data with three-dimensional character have been made available to the project from the Borden Air Force Base Landfill Site (Canada) and the Conroe, Texas, United Creosoting Superfund Site. Future work will focus on the continued development of the three-dimensional model, development of colorgraphics visualization capabilities, and application of this model to real field data.
