Abstract
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.Keywords: Geo-electrical, Contaminant Plume, Cassava effluent, Imaging, Mill
Highlights
As observed by Begun et al (2009), large quantities of pollutants have continuously been introduced into ecosystems as a consequence of urbanization and industrial processes
Leachate plumes generated from cassava effluents can be inorganic chemicals similar to those inorganic contaminations from landfills, open wastes disposal sites, salt brines, acid spills and natural salt-water intrusions
Inorganic contaminations from cassava effluents, cemeteries, open waste disposal sites as well as salt brines, acids spills and natural salt-water intrusion are detectable by electrical methods because of their high values of specific conductance, the application of electrical resistivity tomography in tracking the plume from cassava effluents emanating from the processing of cassava which serves as Environmental pollution and contamination to ground water supply has led to this research work.The aim of this research is to establish the reliability of using geophysical method in mapping contaminant plume of
Summary
As observed by Begun et al (2009), large quantities of pollutants have continuously been introduced into ecosystems as a consequence of urbanization and industrial processes These pollutants can be biomagnified in the food chains, becoming increasingly dangerous to human beings and wildlife. Biochemical processes can mobilize them to pollute water supplies and impact food chains Heavy metals such as Cn, Cr, Cd, Ni, and Pb are potential soil and water pollutants. Heavy metal exposure to human beings occurs through three primary routes namely inhalation, ingestion and skin absorption. All these occur in myriads of places including auto-mechanic workshops. Inorganic contaminations from cassava effluents, cemeteries, open waste disposal sites as well as salt brines, acids spills and natural salt-water intrusion are detectable by electrical methods because of their high values of specific conductance, the application of electrical resistivity tomography in tracking the plume from cassava effluents emanating from the processing of cassava which serves as Environmental pollution and contamination to ground water supply has led to this research work.The aim of this research is to establish the reliability of using geophysical method in mapping contaminant plume of cassava processing mill location in Uzebba Area of Edo North
