dc.description.abstractElectrical resistivity method was used in carrying out geophysical investigation at the Niger State National Youth Service Corp (N.Y.S.C.) proposed permanent orientation camp, Paiko of Paikoro Local Government Area (L.G.A.), with a view to determine the depth to the bedrock and thickness of the weathered basement. The Vertical Electrical Sounding (VES) using Schlumberger electrode array was carried out along five (5) profiles having a total of fifty (50) VES stations. On each profile, were ten (10) VES stations. The data were acquired using ABEM terrameter, Signal Averaging System (SAS) 1000. The field data obtained were analysed and interpreted using computer software (IPI2win and surfer 10) which gives an automatic interpretation of the apparent resistivity data. Results from the interpretation suggest three (3) layers in most parts of the study area. However, there is a case of two (2) layers at a station (VES A6). The resistivity value for the topsoil varies from 10 to 751Ωm with thickness ranging from 0.98 to 4.23m (except for VES A6 where the topsoil has been probably washed off by erosion). The weathered basement has resistivity values ranging from 9 to 968Ωm and thickness of between 0.67 and 24.50m. The fresh basement (bedrock) has resistivity values as high as 2718Ωm. The topsoil is characterized by a top lateritic soil underlain by a silty/sandy clay soil. These soils have great amount of dissolved salts resulting in their low resistivity values. The weathered basements are medium to fine grain, porous or fractured rocks containing water. They are referred to as the aquiferrous zones. The geologic sections derived, suggest that the weathered basement entirely represents a promising aquifer which can serve as the source of water to the area throughout the year. The parameters of investigation have helped in determining the depth to the aquiferous zone, identifying strategic areas such as VES A4, E4, A9, B1, B6, C4, D3 and E3 for siting high-rise buildings, potential positions for the location of boreholes such as VES A1, A3, A7, A8, A10, B2, B4, B5, B7, B8, B9, C3, C6, C9, D2, D7, E1, E2, E8 and E9 and possible depth of sewage system in order to avoid groundwater contamination. This survey revealed that the average depth to the bedrock (Fresh Basement) is about 15.00m with the lowest depth to it as 2.01m and with the highest depth to it as 26.81m. The aquifer in the area has an average depth of about 10.00m and therefore the depth of sewage system should be less than 10.00m in order to avoid groundwater contaminationen_US
