The present study was carried out in Thiruvallur district of Tamil Nadu, India for the assessment of microbial quality of water sources available for livestock. A total of thirty water samples were collected viz., surface water sources such as lake and pond; municipal water supply; ground water sources such as open well and deep bore well. Microbial assessment was performed by using Presumptive Coliform Test (PCT) and Heterotrophic Plate Count (HPC). All the water samples were contaminated with coliforms. The results of MPN levels shows that high level contamination in ponds and lake followed by municipality water supply and were least in open well and bore well both in summer and winter season. The HPC results showed that ground water and municipality water supply had CFU/mL of water in acceptable limits. Whereas the surface water like pond and lake were unacceptably high than the recommended levels, which may pose a threat to livestock. There observed a significantly difference in microbial load (PCT and HPC) (p<0.01) between different sources and in two different seasons, respectively. It was shown that surface water samples had greater microbial pollution than groundwater. Microbial monitoring of water is important to prevent water borne diseases in livestock.
