ABSTRACT-The main objectives of the present study is to access the surface water quality of Mahanadi river in Cuttack city ,Odisha for knowing the suitability of drinking by comparing the primary data with permissible limits for drinking water quality according to World Health Organisation(WHO) and American Public Health Association (APHA).The water samples were collected from different locations of Mahanadi river in Cuttack during winter,summer and rainy seasons.Water quality assessment has been analysed on various physico-chemical parameters like pH,COD(Chemical Oxygen Demand), TDS(Total Dissolved Solids),BOD(Biological Oxygen Demand),TH(Total Hardness),Chloride,Nitrate,Sulphate ,Fluoride and EC(Electrical Conductivity).These are compared to established standards. The obtained results indicate that the quality of water slightly deviates from the potable conditions at some stages.The Mahanadi water is polluted due to the reasons like discharge of domestic effluents,flow of sewage,industrial effluents, biomedical waste,man- made water pollution like immersion waste, Causes of turbidity include soil erosion, waste discharge, urban and algal growth. Turbidity causes the decline in quality of water due to the presence of colloidal particles. Restriction of environmental flows(EFs) affects the healthy water ecosystems. Microbial pollution or contaminated water is believed to be the large single cause of water borne diseases.Realising the importance of this problem, this study aims at determining the present pollution load of the river, EF and based on the findings, suitable models for prediction of the pollution behaviour at different locations of the Mahanadi river and its remedial measures are to be framed.Detailed study is needed to identify the exact reason behind alteration of water quality of the Mahanadi river at different points.
