Water was collected for the analysis of various parameters such as Temperature, 푷푯, Electrical conductivity, Suspended solids, Dissolved solids, Total solids, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Carbonates, Bicarbonates, Chloride The methods used for the analysis are as per standard methods recommended by APHA, WHO. The result obtained was compared with BIS standard and the result shows variation that affects the water quality. Hence water should be treated to reduce the pollution in the water and increase the water quality. KEYWORDS---Netravati river APHA, BIS, Physico-chemical parameter and Water quality. INTRODUCTION Water is aptly described as mother of life. It is a universal solvent. It is the largest medium of life. It occupies 71% of the earth surface, however we need to conserve water as there is very less percentage of clean water. Clean water is essential for life. There are 400 billion gallons of water above, on and in the earth, but it is unevenly distributed [1]. Water is the precious gift of god on the earth. Life exists on the earth because of the availability of water.
