Assessment and EDTA assisted enhancement remediation of physicochemical parameters using Eichhornia crassipes on Yamuna River

Abstract

Water is synonym of life. Industrialization, irregular agricultural practices, urbanization and increase in population are the main reasons for degradation of water quality. Yamuna River is one of the most important rivers of India originating from Yamunotri glacier of Himalaya. The importance of Yamuna River can be understood from the fact that it provides water to Uttrakhand, Delhi NCR and may cities of Uttar Pradesh. Yamuna River is most polluted river in north India. Its water flows from Bandar Punch, Yamuna Nagar, Sonepat, Delhi, Gautam Buddh Nagar, Faridabad, Palwal, Aligarh, Mathura and Agra. For this study, water samples were collected from Dhandupura STP, Agra. The plant selected for this study was Eichhornia crassipes and it was grown in contaminated Yamuna water with two different concentrations of EDTA i.e., 1mg/l and 10 mg/l. The result shows that EDTA remediated and repaired the physicochemical parameters viz. pH, total hardness, electrical conductivity, TDS, biological oxygen demand, chemical oxygen demand, total alkalinity and increased the level of dissolved oxygen of given samples.
