Water quality parameters of Ebe and Ora Rivers collected around the vicinity of the Nigeiran cement factory at Nkalagu were assessed to ascertain the pollution status of both rivers. The parameters with determined using the standard with determined using the standard methods of analysis except for the metals which were analysed using atomic absorption spectrophotometry. The results obtained revealed that there were variations in the levels of the parameters analysed and they were all dedected. The concentration of some parameters such as dissolved oxygen, biochemical oxygen demand carbon dioxide, total alkalinity, total hardness, ammonia, chloride, fluoride, sulphate, nitrate, calcium, sodium, zinc, nickel, chromium and aluminum are within the WHO desirable limit for portable water. Whereas temperature, hydrogen sulphide, pH, iron, manganese, cadmium, lead and arsenic have elerated concentrations in both rivers. The pollution index calculation of 39.258 (site 01) and 24.377 (site 02) for Ebe River; 13.375 (site 01) and 13.463 (site 02) Ora River are indication that both rivers are polluted. This is attributed to the activities of the Nigerian cement factory at Nkalagu in the eastern Nigeria
