To determine bacteriological analysis of drinking water samples taken from various sources like hand pumps, wells, taps, river and ponds in and around Ranchi, Jharkhand, India. Bacteriological analysis includes MPN of coliform and MPN of feacal streptococci. Presence of coliform was detected in 53% of the water samples and the maximum MPN of coliform estimated was 1800+. Faecal streptococcus was detected in 20% of water samples and the maximum MPN of feacal streptococci estimated was 120. The poor microbiological quality of drinking water samples revealed in this study is the matter of public health concern and proper treatment of water is required before its consumption.
