Current Research Activity:
Ensuring the protection of subsurface resources, such as groundwater aquifers, during geologic CO2 sequestration is an important component of risk assessment activities. The release of chemical species regulated by the U.S. EPA Safe Water Drinking Act due to geochemical reactions induced by CO2 migration (or brine migration, both CO2¬-reacted and unreacted) from storage reservoirs into groundwater or shallow aquifers needs to be addressed when assessing long-term residual risk from geologic storage activities.
In several projects being supported by the U.S. Department of Energy, we are working to enhance understanding of potential impacts of CO2 on release, fate, and transport of organic compounds or heavy metals in geological storage formations, and approaches needed for protection of aquifers and subsurface resources. The research is helping to support development of science-based, quantitative methods for calculating site-specific risk profiles as in relation to long-term CO2 storage site stewardship.
