Water pollution examination through quality analysis of different rivers: a case study in India

Restoration of water quality at rivers is a big problem for water quality managers. This paper analyzes water quality parameters across five years from 2012 to 2016 in a case study of different Indian rivers. Recently, Indian rivers have experienced massive contamination and water quality depletion due to the entry of wastewater from different regions of India. The quality of Indian rivers has not yet reached the mark, after many efforts made by the Government of India. For this report, three major Indian rivers (Beas, Sutlej and Ganga) were considered for the water quality calculation. Temperature, dissolved oxygen (D.O), pH, biochemical oxygen demand (B.O.D) and fecal Coliform are the considered criteria for measuring the water quality of the mentioned rivers. Results from the study highlight the water quality of Indian rivers and the current pollution pattern for the river Ganga in 2019, which was not sufficiently discussed before. The level of degradation in water quality of Indian rivers is stated through this study.
