The quality of potable water and treatment of water borne diseases are critical public health issues. Bacterial contamination of drinking water sources is the most common health risk. As water is the most important public need it has to be investigated for its quality regularly, which is crucial for the prevention and control of water borne diseases.Hence this study was aimed to assess the bacteriological contamination of drinking water sources among tap waters, springs and well water in Nekemte Town, January to March 2015. A cross-sectional study on drinking water quality in Nekemte town was conducted by using the membrane filtration technique. A total of 32 springs used for drinking purpose, 2 private and 2 public stand pipes, two reservoirs and 1 well water from each of the six sub cities were selected by multistage sampling. Water sample of 500 ml was collected for each water source. Bacterial culture was made by using Membrane Lauryl Sulphate Broth method.Data analysis was performed using SPSS version 20. And then tables and graphs were used to display the result and important variables.Of the total 65 (100%) water sampled, 5 (31.25%) of the unprotected springs, 4(25%) of the protected springs and the single hand pump were positive; which add up to 10(15.4%) of the total sample size. Whereas the remaining 55(84.65%) were negative for fecal coliforms. Absence of regular disinfection was found to be the major predisposing factor for the contamination of the 10 water sources. Springs and well waters do not have regular disinfection which has resulted in the contamination of 9 spring water sources and the single hand pump. Therefore, regular disinfection of the springs and well water sources has to be implemented.
