The present investigation estimates the Water Quality Index (WQI) for groundwater near to industrial estate Bhilai, Durg District Chhattisgarh. The Water Quality Index was investigated by taking eleven parameters TDS, pH, Turbidity, Total Alkalinity, Total Hardness, Calcium, Magnesium, Chloride, DO, BOD and COD. It was observed that the Water Quality Index values varied from 69.79 to 141.71. The value of the Water Quality Index in some areas shows the sample was unsuitable because of the high concentration of TDS, Hardness and COD. This study indicates a correlation between TDS vs. Chloride, BOD, and Total Hardness and found a positive correlation among them except COD. The water quality index value of groundwater samples near to industries was unfit for drinking purpose, without any suitable treatment.
