Derivation of groundwater threshold values for analysis of impacts predicted at potential carbon sequestration sites

The U.S. Department of Energy’s (DOE’s) National Risk Assessment Partnership (NRAP) Project is developing reduced-order models to evaluate potential impacts to groundwater quality due to carbon dioxide (CO2) or brine leakage, should it occur from deep CO2 storage reservoirs. These efforts targeted two classes of aquifer—an unconfined fractured carbonate aquifer based on the Edwards Aquifer in Texas, and a confined alluvium aquifer based on the...
