Abstract

The study aims to appraise water quality status of some selected areas of Bangalore south district. This has been done by collecting 90 groundwater samples, 30 samples from each of the three selected areas of Bangalore south, and subjecting them to a comprehensive physico-chemical analysis and interpreting the results as per the criteria laid down by the Bureau of Indian Standards for potability. The study indicated that 64.44 % of the water samples tested from the entire study area are nonpotable due the presence in excess of nitrates, total hardness, total dissolved solids and chlorides.

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.
