, Ryznar Stability index (RSI), Puckorius scaling index (PSI), Larson-Skold index (LS), and Aggressiveness index (AI). Based on the investigation, the corrosion tendency in the study area was seen to be 33.33, 30, 80, 93.33 and 20 percent as per the values of LSI, RSI, PSI, LS and AI respectively, while the scaling tendency in the same sequence was observed to be 66.67, 60, 20, 6.67 and 80% respectively. A brief note on the measures that could be employed to mitigate these issues has been indicated.&picture=http://www.aascit.org/aascit/decorators/img/journal/924.jpg)

Depending upon its specific chemistry, water can promote scaling, corrosion or both, and these two aspects remain to be one of the most critical water quality issues in India. Corrosion and scaling tendency of water is an etiology of economic and health concerns in the water supply systems. The present study aims to evaluate to the water stability with respect to corrosion and scaling, in the groundwaters of Bommasandra industrial area in Bangalore, India. Thirty groundwater samples were drawn from the area and subjected to physico-chemical analysis and the analysis results were used to evaluate the Langelier saturation index (LSI), Ryznar Stability index (RSI), Puckorius scaling index (PSI), Larson-Skold index (LS), and Aggressiveness index (AI). Based on the investigation, the corrosion tendency in the study area was seen to be 33.33, 30, 80, 93.33 and 20 percent as per the values of LSI, RSI, PSI, LS and AI respectively, while the scaling tendency in the same sequence was observed to be 66.67, 60, 20, 6.67 and 80% respectively. A brief note on the measures that could be employed to mitigate these issues has been indicated.
