Groundwater plays an important role to cater the needs of the consumer when there is shortage of municipal water supply or potable water. In the present investigation, two groundwater samples, S I at Ramachandrapuram ( Medak district ) and S II at Serilingampally ( Rangareddy district ) were studied to assess the Total Coliform bacteria, Faecal Coliform bacteria and Escherichia coli. The average number of Total Coliform Bacterial colonies were 279/100ml at Station I and 843/100ml at Station II. The Faecal Coliform bacteria and Escherichia coli were completely absent at both the Stations during the study period. It is interesting to note that at Station I, Total Coliform Bacteria were highest i.e. 517/100ml during the pre – monsoon season. At Station II, Total Coliform Bacteria were highest in post – monsoon season i.e. 1207/100ml which can be attributed to the seepage entering into the groundwater. According to BIS 1983 and WHO 1984, the bacteria must be ˂ 10/100ml. The average Total Coliform Bacterial colonies at Ramachandrapuram, S I were 279/100 ml and 843/100 ml at Serilingampally, S II respectively. Hence this study clearly indicated that the groundwaters cannot be used for drinking purposes.
