Abstract
The present study aims to evaluate the Langeliersaturation index and Ryznar stability index for the
groundwaters of K.R.Puram 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 two indices. Based on Langelier
index, 26.67% of the samples were found to be scale forming, 13.33% slightly scale forming, 6.67% were slightly
corrosive, 13.33% indicated serious corrosion and 40% intolerable corrosion, while based on Ryznar stability index,
13.33 % of the samples were found to little scale or corrosive,13.33 % indicated significant corrosion ,6.67 % heavy
corrosion and a whopping 66.67% of the samples showed intolerable corrosion.It is very clear that the results of LSI are
reasonably comparable with the RSI values and the samples show the same property more or less with respect to the two
indices.
