HYDROGEOPHYSICAL SURVEY FOR UNDERGROUD WATER IN FUGAR EDO STATE NIGERIA

Twelve (12) vertical electrical sounding (VES) was done using the Schlumberger electrode array configuration to obtain data and the Schlumberger automatic analysis method of interpretation was adopted. The lithological section of the study area revealed that the area is a basement complex with a thick fresh basement beneath the surface. The weathered basement is a good accumulation for underground water due to its low resistivity values. The interpretation of the data showed a resolution of nine geoelectric layers for the VES locations and a total cumulative thicknesses of 203.55m (677.82ft), and 272.29m (906.73ft) and 27l.43m (903.83ft) depth. From the geologic explanation of the subsurface materials, these values indicate a deeper probing into the aquifer zone. This study would give a guide on effective aquifer layer position in the studied locations (Fugar, Etsako Central Local Government of Edo State).
