Hydrochemical characterization of the water resources in the coastal environments of the outer Río de la Plata estuary, Argentina

Hydrogeochemical processes affecting the chemical composition of groundwater and surface water in the coastal areas of the central and northern sectors of the outer Río de la Plata estuary in Argentina are evaluated. Results indicate hydrochemical differences between the three hydrological units ana...
