On modeling the potential impacts of CO2 sequestration on shallow groundwater: Transport of organics and co-injected H2S by supercritical CO2 to shallow aquifers

Proper site selection for CO2 geologic storage requires assessing the impact of potential leakage of CO2 from deep subsurface reservoirs to overlying drinking water aquifers. Although recent studies have largely focused on the mobilization of trace elements in response to the intrusion of CO2 into such aquifers, in this paper we investigate two other leakage issues and potential effects on groundwater quality: the transport of organic compounds...
