Samples were serially diluted into 10 ml, 1ml and 0.1 ml. Most probable number (MPN) technique was used for the counting of total coliform, fecal coliform and Escherichia coli. The results showed an exceeding value of MPN index / ml and range of 95 % probability in House Wells (≥ 60 MPN), Hand Pump (> 41MPN) and Motor Pump (>20 MPN). The biochemical investigations showed that E.coli contributed 62%, Salmonella 21 % and Shigella were 16 % in total samples.
