Abstract: Water bodies such as rivers, lakes and ponds act like big reservoirs for water supply and at the same time they act as dumping pools for waste discharges. The key step for the supervision of water systems is to obtain information on the changes of quality data with respect to time and place. Water Quality Index (WQI) is a statistical precise tool that converts large water quality data into a distinct and unique number that is easily understood by the public. In the present study, commonly used WQI’s say Weighted Average Water Quality Index (WAWQI) and National Sanitation Foundation Water Quality Index (NSFWQI) were calculated for six streams of River Godavari. The values of WQI calculated for six streams in three seasons were relatively poor and require well-organized treatment before the water from these bodies is used for any purpose.
