Abstract: Surface water is both scarce and threatened due to anthropogenic impact of urbanization, growing population and climate change. Fresh water surface quality mainly of ponds and rivers are vulnerable due to various organic loads, emerging pollutants and water borne pathogens. The presence of suspended particles in water also increases the disease probability as the microbes cling on to those surfaces. Unpredictable weather conditions has heightened the susceptibility towards diseases because this ensures the survival of spore/cysts and inflicts pathogenesis. Non-stop rainfall spreads these pathogens in local water bodies like ponds polluting them and drought conditions concentrate these pathogens in those habitats. Drinking water sources then becomes compromised and results in gastrointestinal diseases like diarrhoea and dysentery which are very fatal for children and immune compromised adults. In this research work, two locality ponds were chosen based on their usage by the people of the surrounding area. Our work highlights monitoring the water quality of these two ponds around Kamarhati locality for coliform group by MPN method. Physico-chemical parameters like temperature, pH, turbidity, Total Suspended Solids (TSS), Total Dissolve Solids (TDS), Dissolved Oxygen (DO) and Biochemical Oxygen Demand (BOD) were also determined as they have influence over microbial growth. Antibiotic susceptibility test of the isolated coliform strains were also performed to ascertain the growing presence of antibiotic resistance in those public use surface water.
