Abstract

The incidence of waterborne diseases arising from pollution of shallow wells in abattoir environment has been on the increase in Ogbomoso community. This project work was carried out in order to examine the geochemical constituents of water samples taken from selected wells in Atenda abattoir environment, Ogbomoso, Oyo State, Nigeria. The effect of abattoir wastes on the groundwater samples and geotechnical analyses of soil samples taken from two points around the abattoir waste dump, and another sample from a control point free from pollution and far away from where the first two samples were taken, were also carried out. Geophysical investigation of the Atenda area was carried out using Vertical Electrical Sounding (VES) of Electrical Resistivity Method (ERM), Electrical Resistivity Tomography (ERT), and also, Very Low Frequency (VLF) electromagnetic method. The geophysical investigation was carried out to determine the lithology of the study area, track the contaminant plume view and compute the depth to bedrock in the study area. It was observed that a strong correlation exist between leachates from the Atenda abattoir location and sampled wells in the immediate environment. A groundwater monitoring programme to determine groundwater quality status of wells in the neighbourhood of abattoirs is recommended for implementation to safeguard the health of innocent residents in the vicinity.
