Estudio hidrogeoquímico y geofísico para determinar el origen y aprovechamiento de las aguas sulfurosas del sector La Banda (Loja)

Abstract

Abstract:The present research work Hydrogeochemical and geophysical study to determine the origin of the sulphurous waters of the La Banda (Loja) sector , had the purpose of developing a 1:10,000 scale geological cartography, which allowed the identification of lithologies as limestones, shales and sandstones, this was complemented by a geophysical study of Electrical Resistivity Tomography (ERT) and Vertical Electrical Probe (SEV) that consented to know the resistivity present in the rocks of the study area, defining the presence of an aquifer. Through a hydrogechemical analysis that included ICP and water quality, for which a sampling of water was carried out at six and seven points respectively, where cation concentrations (Fe++, Mg2+, Ca2+, Na+, K+, As) could be determined and anions (Cl-, SO4 2-, NO3 -, F-, BO3 3-, PO4 3-HCO3 -), which established that the water is sulfate-calcium type and this was compared with water quality standard (NTE INEN 1108), which shows that it is not suitable for the use of human beings.
