A study carried out in river Gagan (India) to assess the extent of pollution by different industrial and domestic activities. Water samples collected from river Gagan at two sites and analyzed for alkalinity, biological oxygen demand (BOD) and chemical oxygen demand (COD) during summer, winter & rainy season. The collected data subjected to statistical analysis and good correlation between alkalinity & BOD and alkalinity & COD is established. Regression equations also established between above parameters to predict the level of pollution of river Gagan. In the present study regression, equation established between two parameters, which can used to predict the value of one parameter if value of other is known. The above study gives us a tool to find the value of physicochemical parameters and extent of pollution theoretically, which is not only time saving but also cost effective.
