Water quality survey and analysis of water sources is mandatory before deciding the suitability of any source for human consumption. Main criteria in determining the quality of water are physico-chemical and microbial parameters. This paper deals with study of physico-chemical and bacterial parameters of different water sources as river, stream and lake of Tawang district in Arunachal Pradesh, India. The study was carried out in the month of September 2017. Standard methods were used for carrying the analysis of collected water samples. Results were compared for water collected from different sources and it was found that contamination level with respect to physico-chemical parameters was within standard limits except bacterial contamination which was above standard limit in nearly all the samples. Maximum Iron concentration was observed in Shungatser Lake i.e 0.36ppm well above the desirable level.
