ABSTRACT: This study was carried out to determine the quality of some water supplies in Jericho and Molete areas in Ibadan, Oyo State, Nigeria. A total of 6 water samples (Jericho and Molete) from well, borehole and public tap were randomly selected and analyzed in triplicate for some physico-chemical and microbial parameters. The pH ranged from 5.88 ± 0.01 to 6.88 ± 0.06 while total hardness ranged from 2.60 ± 0.04 ppm to 44.00 ± 1.20 ppm. The temperature ranged from 15.00℃ ± 0.07℃ to 18.00℃ ± 0.21℃ while conductivity ranged from 230 ± 1.15 to 460 ± 1.26 mho/cm. Alkalinity, Dissolved Oxygen (DO) and Biochemical Oxygen Demand (BOD) ranged from 4.03 ± 0.02 mg/l to 14.88 ± 0.15 mg/l, 0.4 ± 0.02 mg/l to 4.6 ± 0.02 mg/l and 12.80 ± 0.22 mg/l to 26.40 ± 0.72 mg/l respectively. Microbial analysis revealed that all of these water samples were not free from pathogens and thereby not suitable for drinking.
