Resumo

Hydrochemistry was used to assess processes governing groundwater evolution. Evapotranspiration, rock weathering, and ion exchange governed groundwater evolution. Highly mineralized Na-Cl water is controlled by seawater trapped in the estuarine rocks. Groundwater is suitable for drinking but unsuitable for irrigation if left untreat. Some guidelines are being proposed to be followed that may lead to a saving in global water resources while maximizing food production.
