    Investigation of Aquifer Vulnerability and Pollution Index around Industrial Area in Ilorin, Northcentral Nigeria
    (Nigerian Association for Engineering Geology and Environment (NAEGE)., 2022-09-11) Ibrahim, K.O., Yusuf, M.A., and Purchase, M.W.
    Urban pollution due to increased industrialization has become a major concern in recent time. In most cases, hazardous wastes from industries infiltrate groundwater especially in unconfined alluvial aquifer if proper precautions are not taken. This study used GOD model to investigate aquifer vulnerability around industrial area in Ilorin, North-central Nigeria. Heavy metals (Cd, Cr, Zn, Pb, Fe, Ni, Mn, Cu, Co) were also determined from groundwater in study area using metal pollution index (MPI) to validate the GOD model. Three main vulnerability zones were recognized in the study area and these are: low vulnerability zones with GOD index values ranging from0.22 to 0.26 and moderate vulnerability zones having GOD index value of 0.48 while high vulnerability zones possess GOD index values ranging from 0.56 to 0.64. The pollution index show that the area is highly polluted with respect to (Cd, Cr, Pb, Fe, Ni, Mn, Cu and Co) and lightly polluted with Zn. The sources of pollution in the study area are attributed to industrial effluent discharges. There is urgent need for measures to mitigate further groundwater pollution and protection of aquifer in the study area.
