Quantum mechanical electronic structure calculations are playing an increasingly useful role in many areas of mineralogy and geochemistry. This review introduces the density functional method for such calculations, gives an overview of the density functionals developed at the University of Minnesota, and summarizes selected applications using these density functionals that are relevant to miner...
Department of Earth and Environmental Science Environmental Geochemistry Laboratory The University of Texas at San Antonio ________________________________________________________________________ Abstract Century-long disposal of sewage sludge in Mitchell Lake at San Antonio, Texas has resulted in hyper-eutrophic conditions and an excess accumulation of toxic metals in the lake system. To ident...

Environmental concerns regarding the potential for drinking water contamination in shallow aquifers have accompanied unconventional energy development in the northern Appalachian Basin. These activities have also raised several critical questions about the hydrogeological parameters that control the naturally occurring presence and migration of hydrocarbon gases in shallow aquifers within petro...
