ERTH-4690

Aqueous Geochemistry

Fundamentals of aqueous chemistry as applied to the evolution of natural waters. Principles of chemical equilibrium, activity models for solutes, pH as a master variable, concentration and Eh-pH diagrams, mineral solubility, aqueous complexes, ion exchange, and stable isotopes. The carbonate system, weathering reactions, and acid rain are examined in detail. Emphasis is on the chemical reactions that control surface and groundwater evolution in natural and engineered (treatment process) settings. Students learn theory, computation methods, and the use of computer programs for calculation of speciation and mass balance. (Cross listed as CHEM-4690 and ENVE-4110. Students cannot obtain credit for both this course and either CHEM-4690 or ENVE-4110.) Prerequisite: permission of instructor. Fall term annually.
