dc.description.abstractThe survey titled an investigation of groundwater potential of Gada town, Sokoto State using uses vertical electrical sounding was carried out with the aim of determining the ground water potential of the town and to determine as well suitable areas for siting of hand-dug wells. Wells are the only reliable source of water supply in the town and it’s surrounding during the dry season when most of the wells dry up or have low yield. This necessitates the need to search for an alternative source of water supply and hence the need for appropriate geophysical survey to minimize the tendency of drilling abortive or low yield wells. A geoelectrical survey using vertical electrical sounding VES was carried out at 28 VES stations, which were equally spaced at 100 meters intervals out of eight profiles established. The profiles run East-West and North-South depending on the direction of the available spaces, and were labeled A-H. The survey covers Gada town, which is about 2Km2 and the result, obtained from the interpretation of the VES data collected to the construction of geoelectrical and geologic sections. Bore holes logs of the town were also used which aided the interpretation of the section. A total of94 layers were encountered from the 28VES point survey in Gada town, and only 24 layers were found to be suitable for ground water prospecting. The layers were all located at the third and fourth states, and most of them were found on C and E profiles with 5 and 4 points respectively. C I, C2, C3, C4, C5, C6 for C profile and E3, E4, E6, E7, for E profile. A profile has two points at A2 and A4 on the 41h and yd strata, while only one point was located on B profile at B2 point on the 4th layers but highly promising. All the remaining layer points are less significant as they fall within the non-suitable to moderate which are very unlikely to get water.en_US
