Assessment Of Bacterial Quality Of Some Selected Boreholes Water In Kurnar Asabe Quaters Kano Metropolis

Bacteriological quality assessment of different water samples collected from selected boreholes in Kurnar Asabe quarters, Kano metropolis was carried out for a period of six months. A total of thirty (30) samples were collected from 10 selected boreholes in the study area using systematic random sampling technique and some of the physico-chemical parameters such as temperature, pH, electrical conductivity and turbidity were measured on the spot before transporting to the laboratory for further physico-chemical and bacterial analysis. Membrane filters (MF) method was used for bacteria isolation. The total bacterial count was determined by using dilution method. Bacterial identification was done using standard laboratory methods. The physico-chemical parameters of the water samples were within the normal range of WHO limit. The total bacterial count (TBC) in boreholes water samples in this study ranged from 1.0 x102 to 1.1x105 cfu/ml. Similarly, the total coliform count (TCC) of the borehole waters analyzed ranged from 0 to 11 cfu/100ml. Escherichia coli, Shigella, Staphylococcus aureus, Bacillus cereus, Salmonella typhi, Pseudomonas aeruginosa, Enterobacter sp and Klebsiella pneumoneae were identified. People consuming such water are at risk of several clinical symptoms such as cholera, gastro-intestinal disorders, diarrhea and typhoid fever.
