In the present study, microbiological characteristics of the Municipal drinking water were determined in Gwalior City. A total of 18 water samples were collected from different locations and were analyzed for 6 parameters. The results of the analysis showed that the Chloride content ranged from 45 to 83 mg/L at different locations. Residual Chlorine was untraceable in the sample from some sites and the traceable residual chlorine ranged from 0.1 mg to 0.5 mg. There was a wide variation shown by the MPN indexing of the different samples which is between the range of <2 to ≥1600. The samples collected were also analyzed for the presence of E.coli and Salmonella. They were found to be absent in all the samples. The Microbial analysis of the different samples from Gwalior city showed that the current quality of the municipal drinking water in Gwalior meets the quality standards for Chloride, E. coli and Salmonella however, the quality standards for the Residual Chlorine, Total coliform and Faecal coliform was not being met.

 

Keywords: Chlorination,Bacteriological augmentation, Municipal drinking water, Gwalior city.
