This course covers topics related to the behavior and transport of pollutants within and across the three major environmental media namely surface water bodies, soil and groundwater and the atmosphere. It examines the mechanisms, properties and physical, chemical, and biological processes that are responsible for the transport and ultimate fate of contaminants and addresses computational methods and techniques for estimating their movement in space and time, as well as their transformation as they migrate across environmental media and compartments of the earth system. In addition, students learn how to develop and apply mathematical transport and fate models based on the advection-dispersion-reaction equation to create risk assessment plans, pollutant remediation design alternatives and regulatory compliance strategies. The students are also exposed to various transport and fate publicly available software currently used in environmental science and engineering practice.
