    Assessment of Underground Water Potential in Ninga, Akwanga West Development Area, North Central, Nigeria
    (Department of Physics, Nasarawa State University Keffi, 2022-12-12) Ayanninuola, O.S.; Abdullahi, N.K.; Loko, A.Z.; Isah, S.H.; Ogwola, P.
    Ninga area of Akwanga Development Area, North central Nigeria was investigated for the evaluation of groundwater potential. The area is underlain by the Basement Complex of the North-Central Nigeria. Twelve Vertical Electrical Sounding points were identified in the study area using Omega Resistivity Terameter, GPS12Garmix with cable spread of AB/2=160m. Schlumberger electrode configuration was employed. The Vertical Electrical Sounding (VES) data acquired were interpreted into a model curve using IX1D. From this interpretation three (3) different curve types were obtained from the acquired data. They are QH, QA and H. QH type is the dominant type of the curve obtained. It was observed that the aquifer depth range between 8m-46m, basement resistivity 700 Ωm -3700Ωm, depth to basement 16- 56m, aquifer thickness 4m – 31m and aquifer resistivity 150 Ωm -600Ωm. The groundwater potential varies in the study area, VES 1, 4, 5, 6, 7, 9,10, 11, and 12 are viable locations for groundwater exploration, with true aquifer resistivity values range from 150-600Ωm.
