Finding the groundwater in sedimentary rocks is not difficult until a region is covered in thick clay but identifying the fracture zones in hard rock terrain is always incredibly difficult. To solve this issue in the Maredumilli mandal in the East Godavari district of Andhra Pradesh. In this work, the vertical electrical sounding (VES) technique is used to find and delineate subsurface water structures, assess the aquifer's capacity protection, hence estimate the groundwater potential,to find the best locations to drill boreholes in the research area. In order to do that, we used resistivity data from 108 vertical electrical soundings (conducted with a Schlumberger array) in the hard rock terrains of the Eastern Ghat Mobile Belt (EGMB) of the study area. The data were analysed and interpreted using IPI2win software to ascertain the true resistivities and thicknesses of the underlying strata.. Khondalites and Charnockites are the local geology. A serious water problem affects the local population. .The major goal of this research is to locate prospective sources of groundwater using aquifer characteristics derived from secondary geophysical parameters (Dar-zarouk parameters), which might be used to meet human needs for sustenance.
