Studies on Physicochemical Parameters to Assess the Water Quality of the River Damodar

Authors(2) :-S. Banerjee, U. S. Banerjee

The present study was carried out to determine the levels of water quality indicators and to analyze the statistical interrelationships among them. Water samples (n=12) were collected from the river Damodar and prepared for the analysis of various physicochemical parameters. The collection, preservation and analysis of river water samples were carried out according to the standard methods of APHA (1998). The present investigation deals with the study of some water quality parameters like pH, electrical conductivity (EC), total dissolved solids (TDS), DO, BOD, alkalinity, total hardness, SO42, Cl and NO3. The values of most of the parameters were least during the rainy season, when the flow volume increased greatly due to the surface runoff. Dissolved oxygen measures the waste assimilation and self-purification capacity of an aquatic ecosystem and the values ranged from 5.528 to 7.862 mg/l and 5.986 to 8.172 mg/l during rainy season and winter season respectively. Higher dissolved oxygen was found during winter season and relatively lower during rainy season. The results of BOD ranged from 1.278 to 4.878 mg/l and 1.432 to 4.179 mg/l during rainy season and winter season respectively. The result of correlation analysis showed that biochemical oxygen demand (BOD) was inversely correlated with dissolved oxygen (DO). Higher values of nitrate were observed during rainy season may be due to discharge of waste through agricultural runoff. This investigation revealed that the status of the river water quality in the studied region is optimum for fish health.
