In the present study an attempt has been made to determine the wa- ter quality index of industrial outlet and along river Yamuna in Delhi, India. For calculating the WQI, the following eleven parameters were considered: pH, electrical conductivity, total dissolved solids, salinity, dissolved oxygen, biological oxygen demand, total hardness, calcium, magnesium, total alka- linity and chloride. A disturbing observation was the level of dissolved oxygen in Yamuna River at Nizamuddin drain which was found to be nil. The water quality index of gas turbine station outlet was 202.9136 and that of thermal power plant outlet was 207.869. The water quality index of Yamuna River at Nizamuddin drain was found to be the maximum at 262.555 indicating very high level of pollution. The present study revealed that Yamuna River was in a critical condition and the extent of pollution was extremely high .
