From: Geochemical detection of carbon dioxide in dilute aquifers
The geochemical response of carbon dioxide gas in a model sandstone aquifer is shown by difference between High Plains aquifer (symbols, [20, 21]) and simulated groundwater chemistry (solid line) as depth versus pH (a), log [HCO 3 -] (b), log pCO 2 (c), log ΣC aq (d), fraction calcite dissolved (e) and dissolved carbon speciation (f).
