The study examined the water quality of Kakuri-Makera River with the view to determine the abattoir effluents on the quality of the water, investigate the toxicity level and the suitability of the river for human uses. Water samples were collected at three sampling points along the river. One sample was taken at Kurmin Gwari upstream, one sample at Kakuri and the other at Makera downstream. The parameters determined were Temperature, pH, Total Dissolved Solids, Nitrate, Sulphate, Total Dissolved Oxygen, COD, BOD using Standard Method. The metal parameters such as Silica, Iron, Lead, Manganese, Cobalt and copper were determined using Absorption Spectrophotometer (UNICAM, model, SOLAAR 969). The results showed that most of the parameters observed were highly concentrated above the recommended permissible limit set by WHO. This revealed that the Kakuri-Makera River had become contaminated by the abattoir effluents discharged into it and is not suitable for human uses. For sustainable management of the water resource, it is recommended that Simple physical treatment of the effluents from the abattoir could be carried out by use of a retention pond. This is an effective physical treatment method of reducing BOD and COD levels. The abattoir wastewater should be monitored strictly by relevant agencies in order to prevent environmental pollution and reduced health hazards caused by the activities of abattoir wastewater. Wastewater practice by waste reduction, re-use and recycling should be encouraged when and where appropriate and essential. Entrepreneurs dealing in animal wastes such as bones, manure and blood should be encouraged through enabling government policies to convert abattoir wastes to useful products.
