Abstract
Chemical processes in a natural fresh-/seawater mixing zone were studied in a shallow sandy aquifer. The dominant redox-processes are sulfate reduction and methanogenesis. Methanogenesis produces CO2, which causes calcite dissolution. The produced calcium induces ion exchange with sodium. The final result of these interactions between different types of geochemical processes is an anoxic groundwater enriched in bicarbonate and sodium.
