Safe water is the basic needs of mankind. Jaldhaka, Tista, Karola are three main rivers of District Jalpaiguri. The present study compares the water quality of River Jaldhaka with River Karola and River Tista. Some preliminary water quality parameters were selected to assess the present condition of water. The parameters reveal that the water of River Jaldhaka is better than River Karola and Tista before entering to the cities but it must not be considered as a pollution free river. To the search for the probable differences of contaminations among the rivers, the study shows that the sources of pollution are different for them. River Karola and Tista have covered highly populated cities in their catchment but River Jaldhaka before the study point does not pass through residential areas. The pollution entering to River Jaldhaka is mainly by agricultural sources. The findings prove that the surface water pollution is much higher due to urbanization than agricultural and forest lands. So, immediate action to control the pollution must be taken.
