Abstract

Background: Water is a resource that is both invaluable and vital to the existence of all living organisms, but this valued resource is increasingly being threatened as human populations grow and demand more water of high quality for domestic purposes and economic activities. The conducted research was aimed to assessing bacteriological quality of sachet water samples sealed and sold and consumed in some Local Governments. Methods: The bacteriological quality assessment of sachet water samples were determined by Aerobic Plate Count (APC), test for Coliforms and Biochemical Test (IMViC).  The tests were preceded by staining technique. Moreover, the Aerobic Plate Count results revealed various values (CFU)/100ml of water samples collected and examined. Results: Going by zero tolerance levels stipulated by regulatory agencies for coliforms in drinking water, a cumulative figure of twenty five percent (25%)meets the standards of drinking water quality and subsequent percentages were satisfactory, suspicious as well as unsatisfactory which were in conformity with that of world health organization, 2010. The total percentage of good sachet water samples based on this research was 90% and that of bad samples was 10% as indicated. It revealed the presence of Pseudomonas aeruginosa in the sample waters. Conclusion: It has been concluded that most sachets water samples sold and consumed in Kano metropolis conformed with world health organiztion (WHO) recommended standards for potable water and the consumption of some sachet waters whose values are either above or below WHO and SON permissible limit may pose health hazards to the consumers.
