The migration of aluminium in streams upon discharge was studied through mathematical model. Three (3) streams polluted by industrial wastes from beverage, oil drilling fluids and biscuit manufacturing industries in Tras-Amadi in Port Harcourt, Rivers State of Nigeria were selected for this study. The concentration of aluminium and other parameters were measured, however, aluminium ion concentration in the streams were further measured at 10 meters intervals along the streams surface. The investigation shows industrial effluents have impact on the streams’ quality. Also, it was further observed that aluminium concentration decreases with distance away from the effluent discharge point.  However, from about 20 meters away from the effluent disposal point, aluminium concentration was e below the permissible limit of 0.2mg/l. The predicted concentrations were comparable to the measured values, therefore, the high degree of agreement between measured and predicted concentrations of aluminium shows the model can be used for prediction of heavy metals in water bodies.
