Abstract: A study was carried out in river Ram Ganga (India) to assess the extent of pollution by different industrial and domestic activities. Water samples were collected from river Ram Ganga at six sites and analysed for acidity, alkalinity, total dissolved solids (TDS), biological oxygen demand (BOD), chemical oxygen demand (COD) and dissolved oxygen (DO) during summer, winter and rainy season. The collected data subjected to statistical analysis and some good correlation between parameters is established. Regression equations also established between above parameters to predict the level of contamination of river Ram Ganga. The present 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.
