Abstract: The quality of water entering into water distribution network often provides requirements for corrosion and scaling in areas lacking adequate treatment methods, which can cause serious problems. The most commonly used corrosion indices are Langelier saturation index (LSI), Ryznar stability index (RSI). This study aimed to evaluate the corrosion and scaling potential of water resources in Udaipur, Rajasthan. Therefore, the corrosion and scaling potential of groundwater resources were investigated according to LSI, RSI. Scaling and corrosion are from common indicators of water quality and can cause economic and health damages.

According to the results, total hardness and TDS had high mean values, but the values of pH, temperature, and alkalinity were rather admissible. As well, most of the water resources of studied area had low to moderate corrosivity according to LSI and RSI. On the basis of LSI, around 50% result showing that water was slightly scale forming and corrosive and remaining 50% showing that water was scale forming but non-corrosive as mentioned in table 3. Ryznar Stability Index (RSI) showing that 4.5% samples were heavy corrosion, 9.0% samples were light scale, 50% samples were light scale or corrosion, and 36% samples were corrosion significant

Keywords: Scaling, Corrosion, LSI, RSI, Groundwater
