In this study, the physicochemical and microbiological examination of Bahini River was carried out to ascertain their suitability for consumption and presence of microorganisms that could cause water-borne diseases. The water sample was collected from four different sites of the river based on their use by the local people. A total of 10 replications were taken for each site. The results obtained were compared with WHO and EPA standards for drinking and recreational water. With the exception of TSS, Total alkalinity, total acidity and BOD, all others were within the standards set for pH, Total Dissolved Solids, Chloride, Total Hardness, Nitrate, Iron, DO and COD. Though the total hardness were much below the WHO permissible limit, it was found to be a little higher near ISBT and Gorchuk area (95±8.66 and 50 ± 0 respectively). In the microbiological analysis, the Total Viable Count for all the sites were found to be very high. Coliform group of bacteria are differentiated by the presumptive test, confirmed test and completed test. From the test, the MPN index of the water sample were also found to be very high for all the three replicates for all the four sites under study . After performing these tests Gram negative, were non spore forming and rod shaped bacteria having metallic sheen or pink with dark centered colonies on EMB agar indicated positive results. The isolates were characterized and identified as E. coli, Bacillus sp., Enterobacter sp., Klebsiella sp. and Pseudomonas sp. Thus, the study suggests that the river water needs urgent measures to control pollution and also to aware the local people to properly treat the water before using.
