Abstract

: Rivers are the main inland water resources for domestic, industrial and irrigation purposes and often carry large municipal sewage, industrial wastewater discharge and run off from agricultural land.The present investigation attempts to study the physico-chemical properties of river Erai in Chandrapur. The Chandrapur is known for hot and dry climate located around 155 kms. south of the Nagpur at 19° 57 l latitude and 79° 22 l longitude at a height of 321.95 meters above MSL. The seasonal variation in physico-chemical parameters like Water Temperature, pH, Alkalinity, Hardness, DO, Free CO 2 etc. were studied for a year i
