Close to the piedmont, groundwater is fresh and depleted in heavy isotopes like the rain during the humid season (<0.5 mS cm-1; δ18 < -14‰). Close to the recharge zone by the Desaguadero, groundwater has similar characteristics to the mean values of the Rio (2 mS cm-1 and δ180 ≃-10‰). Downstream, a more saline zone (3-6 mS cm-1) presents an isotopic signal of evaporated water and an age of around 3500 BP (14C and hydraulic model).
