This project-based course examines the geochemical reactions between water and the natural system. Water and soil samples collected from a weekend field trip will serve as the basis for understanding principles of pH, alkalinity, equilibrium thermodynamics, mineral solubility, soil chemistry, redox reactions, acid rain and acid mine drainage. The laboratory will emphasize wet-chemistry analytical techniques. Participants will prepare regular reports based on laboratory analyses, building to a final analysis of the project study area. One weekend field trip. Prerequisites: One geoscience course and CHM 208 or CHM 111.
