Detection of Coliform from Public Water Supply in Birnin Kebbi Metropolis, Kebbi State, North-Western Nigeria

Abstract


The study aimed to detect the presence of coliform bacteria from public water supply in Birnin Kebbi metropolis, using standard microbiological water quality analysis (MPN), The total viable bacterial count and coliform  bacterial population in a total of 10 water samples collected over a period of two months at ten strategic points along Dukku water treatment plant and within Birnin Kebbi metropolis demonstrated that the public water supply in in the area  has been heavily contaminated with Salmonella typhi, Escherichia coli, Citrobacter specie, Enterobacter specie  and Serratia marcescens, and did not meet any of the WHO guidelines for water supply fit for any public purposes. As such, indiscriminate treatment, handling, transportation (through pipes) of public water supply could impact on the microbiological quality and promote increase of incidence of coliform bacteria to any public water supply, hence, the demands for necessary actions.
