2D and 3D Subsurface Geo-electrical Resistivity Imaging of Contaminant Plume from Cassava Processing Mill in Uzebba Area of Edo North, Edo State, Nigeria

Electrical resistivity tomography (ert) was used to map and detect the subsurface contaminant plumes from the cassava effluents in the various cassavas processing mill in the study area. the result from the 3d resistivity images showed clearly the distribution of the plumes from all the profile lines in the surveyed area. from the results it is evident that at a depth of 2.5m-21.9m with resistivity values between 6.2ωm-13.1ωm the plumes were observed. the results thus point out the need for environmental education and proper management/location of cassava processing mill by the relevant agencies of government.
