The present work is aimed at evaluating the water quality index (WQI) for the groundwaters of Whitefield industrial area in Bangalore. This has been determined by collecting thirty groundwater samples in and around the industrial area and subjecting the samples to a comprehensive physico-chemical analysis. For calculating the water quality index, ten critical parameters have been considered. The WQI for these thirty samples ranged from 11.58 to 495.07 with an average value of 69.95. 23.33 % of the samples (7 samples) exceeded 100, the upper limit for drinking water. The analysis reveals that the overall groundwater of the area, in general, can be considered fit for human consumption, barring the groundwater from these seven stations, which are non-potable and need some treatment.

Abstract


The present work is aimed at evaluating the water quality index (WQI) for the groundwaters of Whitefield industrial area in Bangalore. This has been determined by collecting thirty groundwater samples in and around the industrial area and subjecting the samples to a comprehensive physico-chemical analysis. For calculating the water quality index, ten critical parameters have been considered. The WQI for these thirty samples ranged from 11.58 to 495.07 with an average value of 69.95. 23.33 % of the samples (7 samples) exceeded 100, the upper limit for drinking water. The analysis reveals that the overall groundwater of the area, in general, can be considered fit for human consumption, barring the groundwater from these seven stations, which are non-potable and need some treatment.
