ABSTRACT

Bacteriological quality assessment of some hand-dug shallow water wells in Awka metropolis was carried out during the dry and wet seasons to determine their potability. The total bacterial, total coliform, faecal coliform and Vibrio chloreae counts were determined using standard laboratory methods. The total bacterial counts during the dry season ranged from 100 to 300 cfu/100ml; total coliform counts, 42-126 cfu/100ml; faecal coliform counts, 10-26 cfu/100ml and Vibrio cholerae counts, 2-10cfu/100ml. During the wet season, the total bacterial counts ranged from 148 to 450 cfu/100ml; total coliform counts, 77-240 cfu/100ml; faecal coliform counts, 12-30 cfu/100ml and Vibrio cholerae counts, 6-13 cfu/100ml. The bacteria isolated during the dry season were Salmonella typhi (7.44%), Proteus vulgaris (18.08%), Pseudomonas aeruginosa (27.55%), Enterobacter aerogenes (35.71%), Vibrio cholerae (2.85%) and Escherichia coli (8.37%). During the wet season, the bacterial isolates were Salmonella typhi (6.14%), Proteus vulgaris (14.56%), Pseudomonas aeruginosa (21.69%), Enterobacter aerogenes (29.70%), Vibrio cholerae (3.66%), Escherichia coli (8.23%) and Klebsiella pneumoniae (16.03%). All the water wells studied were of poor bacteriological quality. Appropriate water purification methods should therefore be developed for such wells to avert a public health hazard.
