ABSTRACT
In India source of drinking water at Varanasi city for common people are tap water, well, hand pump, Ganga river and
stored tank water collected from bore well. All water samples were studied to assess their bacteriological characteristics
and suitability for potable purposes. A cross-sectional epidemiological method was adopted to investigate the drinking water
of six different sites of Varanasi city. The bacteriological examination of water samples included the most probable number
of presumptive coliforms, faecal coliforms, and total bacterial count. The results showed that the total coliform count was
detected in all the site. In all the methods coliforms presence was indicated. Maximum number of coliform observed in all the
seasons, were from river and well water followed by hand pump, tap water and stored tank. The most common group of indicator
organisms used in water quality monitoring are coliforms. These organisms are representative of bacteria normally present
in the intestinal tract of mammals including human. Contamination of water may occur through different way like sewage
disposal in the river, seepage of bathing near sites, fecal excreta of human, bird and other animals. Improving and
expanding the existing water treatment and sanitation systems are more likely to provide good, safe and sustainable sources
of water in the long term.
Key words : Coliform, Disease, Indicator, Water.
