Three decades of research on groundwater transport in highly heterogeneous aquifers, such as that at the Macrodispersion Experiment (MADE) site, has raised many questions about contaminant transport in highly heterogeneous media, the scale for characterization of subsurface heterogeneity, and the effectiveness of various models to predict transport in such systems.

This Chapman Conference is designed to bring together a community of researchers who have conducted transport research at the field scale with those who are interested in aquifer characterization and solute transport modeling to: discuss insights gained from the last three decades of research, consider unresolved questions about aquifer characterization and modeling in highly heterogeneous aquifers, and identify promising avenues for future research in these areas.
