The present study was carried to evaluate the physico-chemical parameters and microbial contamination ofdrinking water in the area of Saggiyan, Lahore. The tested water samples (S1-S30) were found to contain 199.6-402mg/L TDS, 196-260 ppm EC, 196-260 ppm Hardness, 0.8-17 NTU turbidity, 169-290 mg/L alkalinity, 0-0.1 ppbarsenic and 0-0.1 ppm fluoride contents. 95% of the water samples were found contaminated with fecal coliforms while27% of the samples had shown the presence of E. coli. Though the physico-chemical parameters of most watersamples were found in the safe limits of WHO, however, the presence of microbial contamination rendered it nonsuitable for drinking purposes
