Evaluating impacts of CO2 intrusion into an unconsolidated aquifer: I. Experimental data

Capture and deep subsurface sequestration of CO2 has been identified as a potential mitigation technique for rising atmospheric CO2 concentrations. Sequestered CO2 represents a potential risk to overlying aquifers if the CO2 leaks from the deep storage complex. Batch and column experiments combined with wet chemical extractions were conducted to evaluate these risks to groundwater quality and to understand effects of unintentional release of CO2...
