Abstract The Fens is a region that contributes 11% of the agri-food economy from just 4% agricultural land covering England (UK). This vulnerable to soil salinisation sea-level rise with estimated 100-year flood events projected be observed up every 2 years by 2100. Seawater intrusion and upwelling saline groundwater can provide an additional pathway; however, area’s has not been assessed risk ...

[1] Successful geologic sequestration of carbon in deep saline aquifers requires accurate predictive models of rock-brine-CO2 interaction. Often overlooked in siliciclastichosted saline reservoirs is the carbonate buffering of the groundwater. Carbonate minerals are ubiquitous, even in siliciclastic host rocks, resulting in some carbonate buffering. Geochemical modeling of rock-brine-CO2 system...

This work has focused on the possibility of being able to consider the behavior of the caprock, such as a layer of cohesive soil that absorbs and transfers the displacement due to the expansion of the aquifer subject to the action of the flow of CO2 at high pressure, but lower than the overburden of the geological formations overlying the caprock. Assuming a caprock saturated unconfined lateral...

Short-lived radium isotopes (223Ra and 224Ra) are used to investigate the potential association between groundwater discharge and microbial pollution at Huntington Beach, CA. We establish the tidally driven exchange of groundwater from the surficial beach aquifer across the beach face. Groundwater is found to be a source of nutrients (silica, inorganic nitrogen, and orthophosphate) to the surf ...

Abstract Sedimentary rocks with high natural CO 2 concentrations provide invaluable analogues for the long-term engineered storage of . Some previous studies have reported trace metal in sandstone aquifers exposed to , a cause concern should stored leak into underground sources drinking water. However, intensively studied Jurassic aquifer San Rafael–Green River (Utah, USA) area has that are wit...
