Abstract


As industrial activities increase, the risk of contamination of rivers in Ado-Odo Ota Local Government Area of Ogun State in Nigeria is becoming higher. In this study, riverbed sands were collected from five major rivers in Ado-Odo Ota Local Government Area, and conductivity properties were determined after the samples have been treated with varying concentration of petrol, engine oil, diesel, caustic soda and H2SO4. HANNAN Electrical Conductivity Meter, KD2 Thermal Conductivity Meter and Constant Head Method were used to determine the electrical, thermal and hydraulic conductivities respectively. After treatment of the samples with different concentration of the contaminants, it was found that thermal, electrical and hydraulic conductivities of the samples were largely proportional to contaminants concentration in all the samples in general. However, with increase in concentration of caustic soda and H2SO4, increase in electrical and thermal conductivities of samples were observed, while increase in the concentration of other contaminants decreased the hydraulic conductivity of the samples.
