ABSTRACT

This research work application of electrical resistivity method in the assessment of ground water vulnerability was conducted in Iyuku, Estako West Edo State. With GPS coordinator or latitude 07o 08” 22”N to 07 10’ 00”E and longitude 060 14” 18” E to 06 16, 00k. Vertical electrical resistivity materials was used in the assessment of the ground water vulnerability. A schlumberger configuration was conducted using an ABEM tarrameter. This data were obtained in four (4) VES station, the ABEM terrameter display apparent resistivity values digitally as computed from ohms law. It is powered by a 12.5v D.C power source. The data of VES were analyzed using geophysical software IXIDv3 and the geoelectric layers; depth was generated as well as the resistivity spread. The analyzed data was interpreted to reflect the geology of the investigation area with the measured data subject to certain restrictions. Findings revealed that VES1 was a potential aquifer while VES2 as a medium to coarse sand in layer four (4) of the aquifer, in VES3 slit was regarded as the potential aquifer in the layer three(3) and in VES4 very coarse sand is regarded as the aquifer. from the result analyzed it was noticed that the protective capacity rating of the aquifer is poor to moderate and well classification of the aquifer is from low potential to moderate potential. This indicates that the aquifer can be easily contaminated from the mining activities in the study area and the major to mitigate the effect on the environment should be taken.
