Water occupies about 70% of the earth’s surface and yet it is one of the scarcest commodities especially in the developing countries of the world. It is one of the most demanded of all urban and rural amenities and it is indispensable for man’s activities. The importance of Foma River, Ita- Nmo, Ilorin to the populace of some communities near the river in term of provision of domestic water and small scale farming around the river inspired the research into the microbial quality and the physicochemical parameters determination of the water and soil sediment of the river. Forty-eight water samples from four sampling points along the course of Foma River, Ita-Nmo, Ilorin, Nigeria were analysed for their physicochemical and microbiological quality over a period of twelve months. The pH, turbidity, dissolved solids, dissolved oxygen, biological oxygen demand and temperature assessed had high values above permissible level for drinking and recreational activities. The total bacterial counts ranged from 2.7 x 103 - 1.23 x 104 cfu/ml while the fungal counts ranged from 7.0 x 102 - 8.0 x 103 cfu/ml. The bacterial isolates included genera Enterobacter, Proteus, Escherichia , Staphylococcus, Pseudomonas, Sphaerotilus, Erwinia, Bacillus, Shigella, Klebsiella, Serratia, Salmonella and Yersinia while isolated fungi genera included Penicillium, Curvularia, Aspergillus niger, Mucor, Aspergillus, Saccharomyces, Mortierella, Cladosporium, Fusarium, and Rhizopus. The high level of bacteria, physicochemical parameters and presence of coliforms in this river are causes for great concern health-wise.
