Experimental Study and Determination of Water Quality Index of Daya River

Abstract

The present study on spatio-temporal variation and water quality evaluation in river Daya was carried out along its course in nearby Bhubaneswar city of Odisha along the east coast of India, to evaluate the pollution status and variation in physico-chemical parameters of water at eleven different sites. Taking note on the degradation of water quality in Daya river, research was under taken to study the Water Quality index as per National Sanitation Foundation Water Quality Index (NSF WQI). Nine parameters were studied and weight to each factor according to its importance in water quality was considered. Daya the lifeline of southern Bhubaneswar limits its quality as per water quality index and is assessed that the river water is not at all suitable for drinking purpose without conventional treatment and can be accepted as drinking source with strict conventional treatment followed by disinfection, if and only if no other alternative source is present. Water of this river is suitable for class D and class E uses as far as fish culture, wildlife propagation, irrigation, industrial cooling, etc. without treatment.
