Abstract

The present study has been undertaken to assess the corrosion and scaling potential of groundwater quality in Gonbad-e Kavus. The water quality indicators used were temperature, pH, total hardness, electrical conductivity, total dissolved solids (TDS), Cl– 2–, SO4, and Ca2+. The important of water quality indices including Langelier saturation index (LSI), the Ryznar stability index (RSI), aggressiveness index (AI), Puckorius scaling index (PSI), and Larson–Skold index (LRI) has been investigated for 20 water wells supplying the drinking water of study area in 2018. The mean values of LSI, RSI, AI, PSI, and LRI were obtained to be 0.15 ± 0.01, 7.0 ± 0.06, 10.12 ± 1.49, 6.18 ± 0.08, and 0.41 ± 0.05, respectively. The result of the preset study showed that all water resources in Gonbad-e Kavus were corrosive based on the RSI, AI, and PSI indices. But according to LSI, water of the resources was scale forming. LRI index was in not corrosive condition. Therefore, water in these areas will need a special attention. This study demonstrated the application of water quality indices for the estimation water chemical stability and appeared to be promising techniques regarding water quality management that would be useful to environmental experts and policymakers for proper management and treatment of water. © 2020 Desalination Publications.
