Ground water Exploration at the South Western part of Maikunkele village, Niger State Nigeria Using Electrical Method

Abstract

A conventional D.C vertical Electrical Sounding (VES) Survey was carried out in Government Day Secondary School sit, Maikunkele Minna,Nigeria. It lies between latitudes 09˚40ˊ37.17ˊˊ to 09˚41ˊ37.15ˊˊ N and longitude 06˚29ˊ51.55ˊˊ to 06˚30ˊ51.55ˊˊE in the basement complex region of Nigeria. The survey was carried out with the aim of determining the ground water potential of the area, the technique employed in this study is vertical Electrical Sounding (VES) using Schlumberger configuration . A total of 30 vertical electrical sounding (VES) points were located on grid profiles separated at 100m interval between profiles. The data obtained from the field were subjected to geophysical interpretation with the help of computer based program called WinResist software. Result from both the iso-resistivity plots and the vertical sections indicate three geological sections which are the top soil whose resistivity ranges from 10ῼm to about 400ῼm at various depths from 0 m to 1 m the second layer are laterite in some places such as profiles C, D and E and weathered / fractured basement on profiles A and B its depth extend to about 10 meters in most cases. With resistivity below 500ῼm. The third layer which is fresh basement on profiles A and B and parts of C is majorly weathered basement on profiles D,E and some parts of C. The result of this investigation revels that points located within profiles D and E falls within weathered basement to a depth of about 30 meters and can be recommended for any borehole drilling for efficient fresh water production.
