Water occupies an important place in the performance of many vital activities such as circulation, excretion, reproduction, and various other metabolic activities that take place in the body. This study aims to assess the bacteriological quality of surface water sources used for domestic purposes by rural communities in Khana Local Government Area (LGA), of Rivers State, Nigeria. The analysed streams include Bianu, Kaani-babbe, Kor, Kpong and Lubara. The water samples from the various streams were collected once a month for three months. Standard Microbiological procedures were performed to analyze for total heterotrophic bacteria, Shigella- Salmonella, total and feacal coliform counts were determined using the most probable number (MPN) technique. The results of total heterotrophic bacterial counts ranged from; 1.47 ± 0.19 x 107 cfu/ml to 4.60 ± 2.74 x 107 CFU/ml. Total coliform counts ranged from 1.49 ± 0.50 x 105cfu/ml to 5.39 ± 2.03 x 105 CFU/ml. faecal coliforms counts ranged from 0.00 ± 0.00 to 4.05 ± 2.16 x 103 CFU/ml. Salmonella-Shigella counts ranged from 2.23 ± 1.4 ×103CFU/ml to 4.03 ± 1.77 × 103 CFU/ml. The mean range of coliform bacteria for MPN ranged from 1.08 ± 9.08 to 1.60 ± 00MPN/100ml. Faecal coliform bacteria ranged from 3.9 ± 3.6 to 8.66 ± 6.35 MPN/100ml. Thirty- nine (39) bacterial species belonging to thirteen (13) genera were identified, which include: Staphylococcus aureus (7.7%), Klebsiella (2.6%), Proteus (7.7%), Bacillus (12.8%), Salmonella (5.1%), Serratia (10.3%), Pseudomonas (10.3%), Escherichia coli (23.0%), Enterobacter (5.1 %), Shigella (2.6%), Flavobacterium (5.1 %), Chromobacterium (2.6%) and Micrococcus (5.1%). The water from these sources is not safe for drinking and for other domestic uses because of its low-quality thresholds. Therefore, the water sources require further purification to ensure its potability for domestic uses, and there is an urgent need for a safe drinking water supply in the area, to prevent outbreaks of waterborne diseases in these communities.
