The recharge is ensured by meteoric water with an altitude effect. The recharge of groundwater moving in carbonate, karstified formations is ensured by meteoric water that underwent a slight evaporitic loss. The binary diagrams show that the water mineralisation is controlled by mineral dissolution-precipitation processes and by cation exchange.enspringshydrochemistryrechargeisotopeAlgeriaArticle
