Abstract
Background: It is well-appreciated that many communities in developing countries face severe
public-health problems relating to drinking-water. The supply of safe water is important to protect the health of the community people. Aim: The study aimed to evaluate the bacteriological quality of drinking water from various active sources of water utilized in the catchment area of a tertiary care teaching hospital. Material and methods: The present cross sectional study was carried out by the Department of Microbiology and Community Medicine, MSDS Medical College, Fatehgarh during 2013-14. Randomly selected 100 active water sources which were being used for drinking purpose and a fairly good number of people using that water source for drinking purpose were included in the study. National Environmental Engineering Research Institute (NEERI) guidelines for drinking water quality assessment were adopted. Culture and bacteriological tests of drinking water were performed as per
standard protocols. After compilation of collected data, analysis was done using Statistical Package
for Social Sciences, version 21 (IBM, Chicago, USA). Results: Out of one hundred water samples collected, fifty one, twenty seven and twenty two samples
of water were collected from municipal tap water, government hand pump and water cooler
respectively. Almost half of the samples were found to be unsatisfactory. E. coli was found to be responsible for 26% of samples whereas Pseudomonas in 20% of collected samples. E. coli and
Klebsiella tested positive with Methyl Red whereas Pseudomonas sp. and Klebsiella tested positive
with Citrate test reagent. E. coli showed positive result with Indole reagent whereas Klebsiella tested
positive with Urease. Regarding mix population organisms, Escherichia coli, Klebsiella Sp. and Pseudomonas Sp. were found to be positive in 3 samples whereas Klebsiella Sp. and Pseudomonas
Sp. were found to be positive only in 1 sample Conclusion: The study highlighted unsafe nature of current active sources in the study area with
regard to drinking water purpose which are not fit for consumption of water. Surveillance of water
sources and regular bacteriological assessment of all water sources for drinking is recommended on
regular basis.
