Abstract

Water Quality Index is a tool not only to identify the status of the present water quality scenario with respect to priority of parameter against weight value but also to assess the allocation wise suitability towards quality of water. In this paper, water quality index is developed to assess the groundwater scenario of Kolkata city, West Bengal State, India. Eighteen groundwater samples were collected from different locations of the selected site spreading over a period of two year from January 2011 to December 2012 and accordingly physico-chemical parameters have been analysed as per standard procedure. Six parameters have been considered to calculate Water Quality Index such as pH, Turbidity, Total Dissolved Solids, Total Hardness, Chloride and Iron. The tool WQI results show that out of eighteen samples only six water samples are suitable to fit for drinking.
