Abstract: A total of forty water samples collected between July and November, 2019 from five sampling points situated at distance of 0m, 10m, 50m, 100m downstream and 10m upstream (to reflect the ambient condition of the river prior to pollution with abattoir effluent) were used to ascertain the microbiological quality of the river. The mean bacterial counts ranged from 1.3 x 106 cfu/ml to 9.0 x 106 cfu/ml of total aerobic heterotrophic bacterial count, total fungal count ranged from 0.5 x 106 cfu/ml to 1.1 x 106 cfu/ml and the total coliform count ranged from 9 x 104 to 3.5 x 106 MPN/100ml.
