Bacteriological quality of potable water supplying Morogoro municipality and its outskirts (population 135000 people) was assessed by the determination of the most probable number (MPN) of faecal coliforms, Escherichia coli, faecal streptococci and Clostridium perfringens for a period of 6 months. River water and chlorinated pipeborne water were found contaminated with microorganisms in the order of 3·8 x 101 to 4·95 x 103; 3·2 x 101 to 4·5 x 103; 101 to 6·4 x 101 and 1·2 x 101 to 2·5 x 102/100 ml of water respectively. Injured coliforms in treated water averaged 87 %. Pollution of river water by organic matter was much above acceptable standard. These findings indicate that there is a need for further treatment of water before consumption in order to avoid potential health hazards.
