Abstract: Water quality plays a very important role in deciding its suitability for Human consumption and other uses. The physico-chemical parameters of water are the main criteria in determining its quality. This paper deals with study of physico-chemical parameters of different water sources as snow, ground and river water of Leh district. The study was carried out in the month of March 2017. The analysis of collected water samples was carried out using known standard methods. Results were compared for water collected from different sources and it was found that contamination level with respect to physico-chemical and mineral parameters for snow water was less when compared to Leh groundwater, Thiksey monastery and Karu river water. Iron concentration was above the desirable level in all the collected samples. Hence it is recommended that the water should be properly treated for Iron removal before consumption.
