Comparative study of ground water by physicochemical parameters and water quality index

A systematic study has been carried out to explore the Physicochemical characteristics and Water Quality Index (WQI) of groundwater in three big cities (Bhilai, Durg & Raipur) of Chhattisgarh India. Water sample from open wells in various sites of were collected during Jan.–Dec 2011and analyzed for pH, EC, TDS, TSS, total hardness, total alkalinity, COD, chloride, sulphate, sodium and potassium. Comparative studies of samples in different area in the NH-6 highway were conducted, it shows Bhilai water have low hardness comparatively than Raipur area water. W.Q.I values in the present investigation were reported to be 57.35, 75.37 and 61.1. On the basis of all parameters of water we concluded the Bhilai City ground water is not suitable for drinking purpose as compared to other two nearby cities
