All too often simplified assumptions are made to simulate flow and transport of contaminants at sites with complex physical, chemical and biological conditions to enable use of analytical or less rigorous numerical models. But typical contaminated field sites have complicated heterogeneous and/or anisotropic hydrogeology, some have fractures undergoing significant mass exchange with surrounding porous media. The sources of contamination are spatially distributed and/or changing with time. Microbial metabolism activities can proceed in the presence of a variety of electron acceptors. When a site's complexities are ignored, results can often be erroneous and meaningless.

Draper Aden Environmental Modeling, Inc. has developed a finite element model, BIOF&T-3D, that allows:
