This research work investigated the occurrence of Salmonella pathogens in some water sources from Port Harcourt metropolis, Rivers State, Nigeria. Six different water samples, two each from each of the three selected water sources (Borehole, River and Well water) collected from Timber water side River and Choba River; two different wells located in Rumuolumeni, and two different boreholes located in Port Harcourt and were collected and evaluated for percentage occurrence of Salmonella species and other waterborne pathogens. The total heterotrophic count was very high ranging from 2.91xl09cfu/ml in River water to1.5 x 1011 cfu/ml in borehole water, while the Salmonella count ranged between 1.3x103 and 2.9x103 cfu/ml for all the water samples. A total of eight different organisms were identified from a combination of results from the colonial morphological and biochemical tests of fifteen suspected isolates. Five out of the fifteen (15) isolates (WS01, 06, 07, 08 and 14) were identified as Shigella; Salmonella two isolates (WS05 and 10); Vibrio (WS09), Proteus (WS13), Escherichia (WSQ2), Enterobacter (WS04), Klebsiella (WS13) The water samples were analysed using standard microbiological methods. The result showed that all the water samples evaluated contained more than the recommended level of bacteria for drinking water. The presence of these organisms in the water samples reveals that the water sources were faecally contaminated and not suitable for public use.
