This study was undertaken in Nomal Village located in 25 km from Gilgit district. Nomal Valley has an approximate 850 households consisting of 6000 people. The aim of this study was to analyze the state of drinking water quality in Nomal area. Water samples were collected from seven sites in sterilizes bottles. The water samples were immediately subjected to both chemical and biological analysis. The results of these tests were compared with water quality standards of WHO. The water quality parameters namely pH, temperature, turbidity, odor, taste, total hardness, alkalinity and E. coli were determined. The data indicated that pH of all samples was 7, turbidity varied from 5-10 NTU and temperature was 9-25°C. The results showed that physical and chemical parameters of drinking water fall within recommended limits of WHO. Biological water quality analysis indicated that channel water was highly contaminated showing the presence of high fecal coliform. The maximum colonies of coliform present in channel-2 (TNTC) too numerous to count and in tap water 93 E. coli colonies were examined. It indicated that biologically water is not suitable for human consumption. However, chemical and physical quality of drinking water does not have any health hazard problems this time so for. The water far from the source was much polluted as compared to near to the source. Longer the distance water covers it become more polluted because of anthropogenic interaction.
