The important rivers within and around Dehradun district of Uttarakhand are Asan, Tons, Jakhan, Song, Suswa, Rispana, Chandrabhaga and Yamuna. In this work we tried to find out the rivers water quality with respect to physico-chemical parameters, biologically significant few ion concentrations. Pollution river level of any river can be conclude from pH, Conductance, Salinity, TDS, DO and BOD data. It is found that for Suswa conductance, TDS values are high and pH, DO values are low than all other river waters. High DO and low BOD values are found for Chandrabhaga river water. From Physico-chemical parameter data it is clear that Suswa is the most polluted river and Chandrabhaga is the most clean river among these studied eight rivers around Dehradun District of Uttarakhand.
