The bacterial study is a very useful tool for the assessment of water quality in any type of water body and also contributes to understanding of the basic nature of the aquatic system. An overview is given of the different indices for all available water sources present in the 10 different panchyaths of Ananthagiri mandal. The most commonly used indices are based on the estimation of relative abundance of species in samples. Relative abundance can also be used for either a graphical or a mathematical representation of species-abundance relationships, from which diversity indices can be deduced as well. Bioindices of species diversity can be derived from species counts, which are species richness (Margalef index, Menhinick’s index), species evenness/dominance (Simpson index) and a combination of richness and dominance (Shannon–Wiener index), Pielou’s evenness index (E), Berger-Parker dominance index is the number of individuals in the dominant taxon. Valasi Panchayth (Bore and well water samples) were polluted rest water samples were unpolluted regarding the quality of water. Thus we can use this study for the assessment of the water and to resolve the hygienic problems of the water.
