GROUNDWATER PROSPECTION IN THE MUNICIPALITY OF PIÇARRA-PA USING VERY LOW FREQUENCY AND RESISTIVITY

Gilvana Bezerra de Sousa, José Gouvêa Luiz

Abstract


This study was conducted in the municipality of Pic¸arra, located in the southeastern part of the state of Par´a. The aim of the study was to use geophysical methods to map the lineaments associated with bedrock fractures and the nature of the subsoil using the Very Low Frequency (VLF) electromagnetic method and the electrical resistivity in vertical electrical sounding (VES) technique. The integrated analysis of the geophysical data delineated two hydrogeological domains, namely, fracture zones and sediment layers on the bedrock, that could be potential locations of wells for groundwater extraction. The study was designed to identify the most promising units for groundwater extraction and the best locations for the construction of wells to supply groundwater to the city.
