Prospecção de água subterrânea no município de Piçarra-PA usando VLF e resistividade

Abstract

This research was carried through in Piçarra city, located in the southeast of Pará state. The study had as main focus the mapping of lineaments associated with the basement fractures and the subsoil nature through geophysics, using the Very Low Frequency (VLF) electromagnetic and resistivity methods. The integrated analysis of geophysical data allowed the recognition of two hydrogeological domains in the area: Fractured zones and sediment thickness above the basement rocks, aiming to guide the location of groundwater captation wells. The study provided indications of the most promising locations for groundwater captation and the best sites to build water wells for the city supply.
