Mula, Mutha and Pavana are the three major rivers of Pune on which the city mainly survives. In view of this, maintenance of quality of these waters is imperative and hence needs regular auditing. Present report is an investigation into the water quality of these river waters carried out at different locations during all three seasons in the year 2015 taking into consideration 18 physico-chemical parameters. Water samples were collected from nine different locations covering all the three rivers. The combined effect of various physico-chemical parameters is studied through calculation of Water Quality index for all these samples. Water quality of Khadakwasla was found to be good whereas for majority of the locations it is medium irrespective of the season in which it is studied, which is in agreement with the previous studies. At Yerwada and Aundh the water samples showed bad quality during all the seasons irrespective of the seasonal variations which speaks about the high pollution levels at these locations. It has been concluded from this work that seasonal variation does have an impact on water Quality Index (WQI) and serves as an indicator for the pollution levels in the waters of Pune.
