Teaches, using simple analytical models how physical, chemical, and biological processes in the subsurface affect contaminant transport Uses simple analytical models to demonstrate the impact of subsurface processes on the fate and transport of groundwater contaminantsIncludes downloadable modeling tool that provides easily understood graphical output for over thirty modelsModeling tool and book are integrated to facilitate reader understandingCollects analytical solutions from many sources into a single volume and, for the interested reader, shows how these solutions are derived from the governing model equations
