Análise hidroquímica e estudo geofísico das águas subterrâneas da Coxilha São José, no município de Caçapava do Sul-RS

Abstract

This research aims to characterize the hydrogeological potential of Coxilha São José, located in the county of Caçapava do Sul, Rio Grande do Sul. Understand the spatial distribution of the resource, flow, quality, and viability. This study involves the evaluation of physical, chemical and hydrodynamic parameters of aquifers belonging to the region. Caçapava do Sul is located in the region of three watersheds, Baixo Jacuí, Rio Camaquã, and Vacacaí - vacacaí mirim, and in the study area, the urban perimeter of the municipality, is a crystalline aquifer, which is composed mainly of igneous and metamorphic rocks, mostly granite rocks that have a high degree of fracturing and failure. The methodology of the research will apply bibliographical surveys, application of geophysical methods, structural characterization through satellite image data, fieldwork, collection and analysis of groundwater. As a result, it was possible to identify the chemical parameters of the water collected in the tubular wells, as well as to compare them with the limits established for the potability Standards in relation to human consumption, besides the subsurface identification and analysis with the aid of geophysics.
