Geochemical Modeling

Two important cases of society’s mega-environmental projects are high-level nuclear wastes and CO2 storage in geological repositories. For both of these cases, the chemical reactions on the time scale of at least 10,000 years and their effects on the repository safety need to be evaluated. Industrial applications of geochemical modeling also abound, including groundwater remediation, water treatments, diagenesis related to oil and gas emplacement, enhanced oil recovery, and ore deposit formation. Models allow evaluation of the coupling and feedback among multiple processes in complex systems.
