WATER QUALITY ASSESSMENT OF PUNASA DAM (INDIRA SAGAR DAM), MADHYA PRADESH

Abstract

The Indirasagar Dam (Punasa Dam) is a multipurpose key project of Madhya Pradesh on the Narmada river at Narmada Nagar in Khandwa (Tehsil of West Nimar district) Madhya Pradesh in India.The physical and chemical properties of water including temperature, pH, transparency, dissolved oxygen, biological oxygen demand, hardness, nitrate, calcium and phosphorus concentration, were monitored from October 2018 to September 2019. The physical and chemical parameters were analyzed as per APHA, revealed that there were fewer variations in the physicochemical parameters and results received through the entire one year of study showed that the status of water quality is quite normal and within the permissible limit as mentioned with ISI.Moreover, according to the findings of this research and their comparison with the national and international water quality guidelines/standards, it could be said that the water quality of Punasa dam during the study period was acceptable. However, due to the changes occurred in nitrate and phosphorus and extensive development of eutrophication problem, accurate and continuous evaluation of water quality in this reservoir is deemed necessary.
