Hydrogeological sections of the Pergamino basin (Buenos Aires Province, Argentina): Audio magnetotelluric and geochemical results
Aquifers in the northeastern zone of the Buenos Aires Province, mainly used for agricultural purposes, were studied regionally by several authors, but local studies are necessary because great variations may occur in different basins, and well data are limited. In this work, geophysical exploration...

Aquifers in the northeastern zone of the Buenos Aires Province, mainly used for agricultural purposes, were studied regionally by several authors, but local studies are necessary because great variations may occur in different basins, and well data are limited. In this work, geophysical exploration by means of Audio-magnetotelluric soundings and geochemical analyses of some well data were carried out at the Pergamino rivulet basin. Depth and thicknesses of the upper hydrogeological section, the Epiparaniana, including the Pampeano and Puelches aquifers, were determined. Also, the hydro chemical evolution along the direction of regional groundwater flow was studied. The depth of the very conductive layer corresponding to the salty Puelches and the "Green Miocene", limiting the agricultural water usage, came out to be very variable depending on the zone. Geochemical analyses showed that the Pampeano aquifer has bicarbonate sodium water, with an increase of electrical conductivity, sodium and bicarbonates contents at a local recharge zone with impermeable and bad drainage soils and a topographical small slope. |
