ASSESSMENT OF WATER QUALITY STATUS OF LAKES IN HARYANA, INDIA

Abstract

Water is very important natural resource available on earth and is present in both forms as surface and sub-surface sources, but because of the gradually increased water pollution is finishing its potability. In this system, it has become important to monitor the water quality. Lakes are efficient inland aquatic systems and also it shows different types of functions like provide drinking water, irrigation and water for use of industrial purpose, also for disposal of waste, for fishing and recreational sources etc. are polluted due to various natural and organic evolution disturbances and all of these disturbances in their water quality can be checked by obtaining the WQI to check the purpose for which the water can be used for. In this study, the water quality assessment of five lakes Sukhna lake, Brahma sarovar, Sultanpur lake, Sohna lake , Sanhit sarovar was done by judging water by using the 10 physico chemical parameters to find out the water quality index of every lake. Four parameters (turbidity, Dissolved oxygen, Biological oxygen demand and EC) were not found within permissible limits when they were matched with standards given by ICMR/BIS. WQI results proved that the water quality of every lake is presently in very very bad condition. The results were matched with the values mentioned by respected organizations (WHO and BIS) for measuring the water quality and these proved that the lake water was turbid and under DO distress.
