Abstract
The present study has investigated the status of physico-chemical contaminants in river Sutlej in Punjab state. The physico-chemical parameters, such as pH, EC, DO, BOD, COD, total coliform, faecal coliform and NO3 have been analysed at ten sampling stations from 2002-2015 for pre-monsoon and post-monsoon seasons. The results were compared with water quality standards prescribed by the Bureau of Indian Standards (BIS). The correlation coefficients were calculated to detect highly correlated parameters. The study suggests that the quality of river Sutlej becomes extremely deteriorated due to toxic industrial and domestic discharge near Phagwara and Ludhiana city. Significant increase in biological oxygen demand, chemical oxygen demand, faecal coliform and total coliform can be witnessed at the confluence of Buddha Nallah and East Bein.
