Article Overview


This study investigated the bacteriological quality of river nun at Amassoma section, Bayelsa state. Nine water samples were obtained from three location (upstream, midstream and downstream) i.e. three from each location. Standard bacteriological procedures were employed for the analysis. Results showed that Total heterotrophic bacteria, total coliform, fecal coliform and Salmonella-Shigella counts ranged from 1.78 to 9.30 x 106 cfu/ml, 23.00 – 28.00 MPN/100ml, 13.67 to 18.33 MPN/100ml and 0.00 – 3.23 x 102 cfu/ml respectively. Analysis of variance showed that there were no significance differences (P>0.05) among the various location beside total heterotrophic bacteria that showed significance difference (P<0.05). The bacteria population exceeded World Health Organization/Food and Agricultural Organization allowable limit of 1.0 x 102 cfu/ml for potable water and Standard Organization of Nigeria maximum permissible level of 10cfu/ml for total coliform. The bacteria tentatively isolated were Staphylococcus aureus, E. coli, Pseudomonas, Enterobacter, Corynebacterium, Bacillus, Micrococcus, Proteus, Salmonella, Shigella species.  Based on the density and isolates the water is unfit for human consumption. Hence it can be suggested that the water from River nun at Amassoma section is not potable based on bacteriological quality except when treated using suitable treatment technology such as chlorination and boiling.

Keywords: Amassoma, Microorganisms, River Nun, Water quality.
