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.
