Abstract
Bacteriological quality has been evaluated for drinking water in Lucknow district, Uttar Pradesh, India at twenty different sites during Nov-Dec 2007. Drinking water at almost all the sites was found to be highly contaminated, except at a few sites. Alarmingly, the contamination was greater in the ground water as compared to the piped water supply. Source wise observation revealed that 66.6% piped water and 75% of ground water samples (Hand pumps) were found to be bacteriologically contaminated and unsafe for drinking purpose. Thus present study suggests that water samples are highly contaminated with feacal material, which may be taken as a source of gastrointestinal disease. It was observed that some effective measures are urgently required for periodic water quality monitoring with special emphasis on proper disinfections and maintenance of drinking water source.
