ABSTRACT
Ten streams (10) (ST) water samples were randomly collected. The
water samples were analysed by the Multiple Tube Method,coliform
counts were determined by the Most Probable Number (MPN)
technique; and result ranged from 0 - >18 orgs/100 ml. Isolates were
further identified by routine laboratory techniques. Escherichia coli
was predominant in 9(90%) of ST. Other isolates include Salmonella
and Enterobacter spp, 4% each in the total samples, followed by
Klebsiella spp, 3%; Proteus spp and Bacillus spp with 2% each in 10
samples. The result indicates a recent and (perhaps continuous) faecal
pollution arising from poor hygiene and failure of treatment processes.
This does not meet the WHO standard for potability. Potability of
water deteriorates during the rainy months due to
flooding/eutrophication and seepage.
