The Study Of Physico- Chemical And Bacteriological Parameters Of River Salandi And Assessment Of Water Quality Index From Hadagada Dam To Akhandalmani, Bhadrak, Odisha, India

Abstract

The River Salandi, originates in well-Known biosphere of Similipala reserve forest of Meghasani hill under Mayurbhanj district and joins with the river Baitarani at Tinitaraf ghat, near Akhandalmani, after running through Hadagada dam, Bidyadharpur Barrage, Agarapada Town and Bhadrak municipality. The river, in its course of flow from Hadagada to Akhandalmani containing 134 Kms. of distance receives both treated and untreated effluents from the mines, industrial effluents from Ferro Alloys Corporation (FACOR), agricultural effluents, urban wastes as well as bio medical wastes. This paper deals with the analysis of Physico-Chemical and bacteriological parameters of water samples, collected from nine different monitoring stations during summer (April & May), rainy(August), post-rainy(October) and winter seasons (December & January) in the year 2015 and 2016 by using standard procedures. The water quality index (WQI) calculated for the year 2015 and jointly for 2015-16 by computing mean values of twelve important parameters of the corresponding years with the help of weighted Arithmetic method reveals that different monitoring stations have different water quality due to contamination of hexavalent Chromium, Iron, Calcium, Fluoride and other organic pollutants. The no station comes under quality 'A' and 'B' and the water of river is unfit for drinking purpose without proper treatment.
