Analytical Studies on Water Quality Index of River Tapti

Gajanand Thakre, Neelesh Shrivastava and P. K. Mishra

River Tapti is of particular importance in the study of surface water pollution because municipal sewage, agricultural and urban run-off are discharged into it bringing about considerable change in the water quality. This study was aimed at using the application of Water Quality Index (WQI) in evaluating the quality of River Tapti for public usage. This was done by subjecting the 52 water samples to comprehensive physicochemical analysis using APHA standard methods of analysis. The WQI for the samples was 234.19. The high value of WQI has been found mainly from the higher values of total dissolved solid, phosphate and sulphate, COD and turbidity. The results of the analysis, when compared with World Health Organization (WHO) permissible limit indicated that the river was polluted and so the water is not safe for domestic use and would need further treatment. The present study demonstrated application of water quality index in estimating/understanding the quality of river water and appeared to be promising in the field of water quality management.
