Water is one of the most abundant compounds found in nature covering the largest part of the earth’s surface. In spite of this apparent abundance, several factors tend to limit the amount of portable water available for human use. In this work, physico-chemical properties of water such as temperature, pH, colour, conductivity, hardness, chemical oxygen demand etc. as well as the concentration level of heavy metals and composition of effluents in Ala River was determined and analysed vis-à-vis W.H.O standard so as to determine its suitability or otherwise for domestic, industrial and agricultural purposes. Results obtained indicate that most of the water parameters determined for Ala River were within the permissible limits stated by W.H.O for portable water, except for Mn, Ni, and Pb which are beyond the limits. Also, Chemical Oxygen Demand (C.O.D) is not high for samples (3.50-15.80), an indication that the water is not heavily contaminated with heavy organic matter. The presence of Cd, Hg was not detected in the water samples which make the water safe for various usages, though some degree of treatment is required to make it fit for consumption purpose.
