The purpose of present study is to calculate “Water Quality Index” (WQI by Weighted Arthematic method) of a medium sized river “Chhoiya” in Bijnor District of Uttar Pradesh so that it can be ascertained that the quality of water is fit for public consumption, recreation, irrigation and other purposes. It also assesses the impact of various activities e.g. Human activities, agriculture and Industrialization. Physical and chemical parameters are monitored and used for calculation of WQI for three seasons namely rainy, winter and summer. The parameters are pH, electrical conductivity, total dissolved solids, total alkalinity, total hardness, total suspended solids, Nitrate, Sulphate, Dissolved oxygen and BOD. Water Quality Index is a number which indicate water quality in terms of index number. In water qulity management programmes WQI is useful tool to represent overall quality of water. A study was done from July 2017 to June 2018 on river Chhoiya to assess the quality of water and its suitability for various purposes.
