Abstract: The present project ‘Water Quality Assessment of river Ganga Health Hazard Identification and control’ includes tests for, pH value, Electrical Conductivity, Total Dissolve Solid, Hardness, Alkalinity, Chloride, Nitrate, Sulphate, Iron, Sodium, Potassium, Calcium and Magnesium. Result was compared with drinking water standard prescribed by BIS 10500-2012 and all parameters satisfied the prescribed limit given in BIS standard for drinking water. Water Quality of river Ganga from Gangotri to Haridwar is found Pollution free. Spatial variation in river water quality is shown by Quality Contour Map by using Surfer Software 9.0 version. Maximum water quality deviation from mean value is observed at Haridwar which shows the adverse impact of Industrialization, Urbanisation and Rapid growth of population on the river water quality.
