Reactive Transport in Soil and Groundwater Processes and Models [Paperback]

In this book, the authors focus on the improvement of the scientific base for the development of environmental risk indicators measured by the presence of pollutants in water and porous media. In pursuit of a correct and complete numerical approach, they deliver insight into the understanding of integrated process, and also of modeling capabilities.

Technologies for soil remediation require real knowledge and understanding of the processes involved and a correct and complete numerical approach in order to reach the best results at the lowest possible cost. The authors focus on the improvement of the scientific base for the development of integrated indicators of the environmental risks created by the presence of pollutants in water and porous media. They deliver insights into the understanding of integrated process, and also modeling capabilities. The establishment of a set of integrated indicators to evaluate the pollution status and risk of water resources will considerably aid environmental agencies, administrators and regulators and profit the society as a whole.
