The study evaluates and compares the quality of drinking water from different sources, available for consumption in holy city of Mathura. Total 180 water samples from household sources, public places and packaged water were subjected to physico-chemical and microbiological analysis. The odor and color of all the samples were within the acceptable limits. The pH, Total Dissolved Solids (TDS) and Standard Plate Count (SPC) range was 6.5-8.9, 20-2000 ppm, 0-105 cfu/ml, respectively. Total coliform count ranged from 0 to >1800 Most Probable Number (MPN) per 100 ml of water at 37oC. High counts upto 130 coliforms/100 ml were observed in locally packaged water whereas no coliforms were found in reputed brands. Overall prevalence of E. coli in samples was 10.56% (19/180), with highest prevalence in drinking water available at public places (21.67 %). No E. coli O157:H7 could be isolated. The difference in various parameters was statistically significant (p<0.05) when compared with BIS and WHO. Drinking water available at homes and at public places did not meet the WHO standards for drinking. RO and packaged water were found safe and within the standards.
