This study was carried out to access the Physico-chemical and microbiological quality of three brands of bottled water (A, B, and C), by comparing the compliance of each brand with W.H.O standards. A total of 15 parameters were analyzed: the pH, conductivity, temperature, total dissolved solids, total suspended solids, turbidity, chloride, sulphate, biochemical oxygen demand, total coliform, sodium, iron, lead, and cadmium, using the standard method at Dukoria laboratory. The results obtained for sample A, B and C were; Ph (6.20-7.28), Conductivity(65.67-102.57µs/cm), temperature (27.9-28.70c),Total Dissolved solids (36.78-57.40mg/l), Total suspended solids (0.00-0.50mg/l), Turbidity (0.00-1.00mg/l), Chloride (11.40-18.50mg/l), Sulphate (0.04-0.06mg/l), Dissolved oxygen (4.71-5.81mg/l), Biology Oxygen Demand (0.50-0.92mg/l), Total coliform (<0.031),respectively, Sodium (6.50-9.60mg/l), Iron (<0.001mg/l – 0.006mg/l), Lead (<0.001mg/l) respectively and Cadmium(<0.001mg/l) respectively. From the 15 parameters analyzed, all the samples were in line with the permissible limits except for the pH of brands A and C having 6.45 and 6.20 respectively. The coliform bacteriological count of the samples complied with WHO standard 0cfu/100ml making the water potable for drinking. The concentration of heavy metals in all sample complies with the W.H.O standard, making the water safe for drinking. Proper treatment should be embarked on so as to improve water quality and suitability for human consumption.
