Experimental study on the water quality of Sursagar lake

Abstract

Sursagar Lake is the largest and oldest lake in the city of Vadodara, unarguably charming in its earlier years. During the festival of Ganesh Chaturthi, locals immerse the idol of Lord Ganesha in the lake over a period of ten days causing almost irrevocable harm in the form of pollution to the lake. This paper focuses on the quality of water determined by experimental methods before and during the festival of Ganesh Chaturthi (August 2015). It also discusses plausible methods for improving the water quality of the lake. Water samples were collected in order to analyze chemical parameters (COD, DO, pH and TDS) and the results were compared with the respective regulatory values. A high level of variation of TDS was observed in the lake, post the celebrations as a result of aforementioned idol immersion.
