Estudios sedimentológicos, geohidrólogicos y geoquímicos para la evaluación de fuentes alternativas de agua subterránea dulce en sectores del litoral de Bahía Samborombón, provincia de Buenos Aires

Abstract: La planicie costera del Río de la Plata se desarrolla en el litoral noreste y este de la Provincia de Buenos Aires, donde una de las principales limitantes para el desarrollo socioeconómico es el predominio de agua subterránea salina. Asimismo, el litoral de Bahía Samborombón, en la planicie costera del estuario exterior, es la zona con mayores problemas de abastecimiento de agua ya que aquí, contrariamente a lo que ocurre en la planicie del tramo inferior y medio del estuario, también en las zonas más contine… Show more

“…Similarly, these samples are characterized by presenting low Na + contents (Figure 5b,c), Na + -Cl À ratios versus (HCO 3 À +SO 4 2À )-(Ca 2+ +Mg 2+ ) close to zero (Figure 5d), and positive values of Cl À -(Na + +K + )/Cl À associated with high values in the concentration of Ca 2+ +Mg 2+ (Figure 5e). On the contrary, although the flow deepens, the system loses its capacity of incorporating CO 2(g) and pH starts rising, reaching supersaturated values in the saturation index of calcite (Tanjal, 2021) and changing to the dominance of Na-HCO 3 type waters at the deepest sectors of the aquifer. However, the high concentrations of Na + observed in the deep part of the aquifer below the bioturbated clays show that there must be another process that determines the change of facies.…”
