Abstract: Abstract: A study was conducted to evaluate the quality of drinking water of Mysore city. A total of 226 drinking water samples were randomly collected from 72 bore wells (hand pump), 77 taps from consumer points and 78 stored household water. The samples were analyzed for bacterial contamination. Among all the samples collected 20% of tap water samples were contaminated, followed by bore well water 11% and stored household water 73% contaminated with enteric bacteria. During the study 232 isolates of enteric bacteria were identified of which 61 of E. coli, 76 of Klebsiella, 74 of Citrobacter and 21 of Salmonella were isolated. Coliform contaminations in household water were high even when source water was of good quality. The present study highlights the population's hygiene, health behaviour and environmental sanitation.
