WATER QUALITY ANALYSIS OF YAMUNA RIVER IN FEW SELECTED SITES OF YAMUNANAGAR, HARYANA

Yamuna River is the fifth longest river and is one of the major rivers of north India. The river flows through the states of Uttarakhand, Haryana, Delhi and Uttar Pradesh. It has been exposed to anthropogenic pollution, such as industrialization, deforestation and urbanization for many decades, and has become so polluted that it exceeds the permissible limit. The study was carried out at two different sites (Shiv Temple and Near Old Bridge) of Saraswati Sugar Mill, (Rampura Colony Yamuna Nagar) and other two different sites (Old Bridge Midstream and Below Old Bridge, Kalanaur) of Dheen Bandhu Chhotu Ram Thermal Power Plant, the places covered in Yamuna Nagar, Haryana, dealing with various physico – chemical parameters such as pH, biochemical oxygen demand (BOD), chemical oxygen demand (COD), dissolved oxygen (DO) and microbial population levels by following the standard method. It was found that the pH values of river water were recorded as minimum of 6.7 at Old Bridge Midstream, Kalanaur 1 KM upstream of Dheen Bandhu Chhotu Ram Thermal Power Plant and maximum of 7.6 at Near Old bridge of Saraswati Sugar Mill, Rampura Colony, Yamuna Nagar. All the selected sites show increased values of BOD and COD ranging from 80 to 120 ppm and 180 to 300 ppm respectively, which are above the permissible limits and ensures the presence of wastewater sewage. The purpose of the study is to create general awareness to control further pollution and make water fit for domestic and agricultural use to some extent in the future.
