Abstract
The Ganges is the most significant perennial river of India, both in terms of being a valuable water resource and also maintains a spiritual status. The ill effects of urbanization and improper waste management is leading to the (irreversible damage) pollution of the ganga water, making it unsuitable for many purposes. The present study is an attempt to investigate the water quality parameters, on the scale of dissolved oxygen in nine different ghats of river Ganga, from Ray ghat to Ahiritola ghat, covering an area of 20 km, in and around city of Kolkata. Levels of dissolved oxygen (DO) gives a measure of the primary productivity of the water ecosystem. The DO values have been analysed by the Winklerâs iodometric method to reflect on the condition of the water quality. The findings from this study provides a sample overview of the status of dissolved oxygen levels in the river Ganga.
