Migration and transformation of manganese during the artificial recharging of a deep confined aquifer

Field tests and laboratory experiments were performed, using an artificial groundwater recharging site in Southeast China as an example, to investigate the migration and transformation of manganese during the artificial recharging of a deep confined aquifer. The migration and transformation of total manganese and divalent manganese (Mn(II)) were influenced by mixing, oxidation reactions, and the dissolution of minerals containing manganese, and...
