dc.description.abstractElectrical resistivity and Electromagnetic data were acquired using Schlumberger and VLF techniques to investigate zones of favorable groundwater conditions in the hard rock of Federal Housing Estate Akure, Ondo state, Nigeria. The static water level of the study area ranges from 0.3 m – 4.2 m. Four prominent lithological series delineated are topsoil, weathered layer, fractured basement, and fresh basement. The topsoil has resistivity ranges of 73-267 ohm-m and thickness ranges of 0.4-5.1 m. The weathered layer has resistivity ranges of 41-205 ohm-m and a thickness range of 1.1 -8.4 m while the fractured basement has a resistivity range of 85-2387 ohm-m and its thickness varies from 40 to 122.5 m. The low resistivity in the fractured basement which shows in all four traverses could indicate the presence of conductive matters such as water in there. Fresh basement has the highest resistivity of 20614 ohm-m, indicating the freshness of the hard rock in the area. A significant highest positive filtered real VLF value of 40% that indicates high conductivity occurs at traverses 2 and 3 while 1 shows as much as 30%. In conclusion, the interpretation of results of the stations along four established traverses revealed that the area of generally favorable groundwater conditions provided the fractured zones are fully penetrated within the basement in other to exploit a reasonable quantity of water from the area.en_US
