Overlying groundwater

WebAn aquifer is a rock formation that has the capacity to host large quantities of groundwater. Well-defined aquifers consist of unconsolidated sedimentary rocks such as gravel and sand, ... occur where groundwater is confined under pressure greater than the atmospheric pressure by the overlying, relatively impermeable strata. WebModel results showed that the potentially adverse impacts of leakage on shallow groundwater quality may be exacerbated for cases of leaking CO 2 +H 2 S, compared to intrusion of pure CO 2, possibly leading to the mobilization of thiophilic elements such as arsenic. Geochemical reactions included in the simulations involve adsorption/desorption ...
