“…Measured (Xia et al, 2000) and calculated H 2 S solubilities in 6M NaCl solution at 80 o C (right) and 120 o C (left). 116 In the first part of an EPA-funded project on potential effects of carbon capture and geologic storage (CCS) on groundwater resources (Birkholzer et al, 2008), we evaluated the potential for mobilization of trace elements in response to CO 2 intrusion via systematic reactive-transport simulations involving hypothetical release scenarios Apps et al, 2010). Other researchers have investigated this issue by laboratory experiments (e.g., Carroll, 2009;McGrath et al, 2007;Smyth et al, 2009) as well as modeling work integrated with controlled field experiments of CO 2 release in freshwater aquifers (e.g., Kharaka et al, 2010;Ambats et al, 2009).…”
