Characterization of the Co2 Springs Associated With the Bongwana Fault, Its Impact on Fresh Surface Water and Groundwater Quality and Implications on Carbon Capture and Storage (Ccs) In South Africa
The natural CO2 springs at the Bongwana area emanates from a number of sites along an 80 km long N-S trending fault known as Bongwana fault. CO2 rich groundwater is observed at a shallow depth in a borehole drilled for water supply parallel to the main fault. The geology along the entire fault length is characterized mainly by Dwyka Group sediments. The objectives of this study are to characterize the CO2 springs and assess their impacts on groundwater and surface water quality.
