Background and purpose: In the area of water quality issues, much attention has been paid to water corrosivity and scaling potential since the water tendency to each of them can impose huge financial losses and many health problems.
Materials and Methods: In this descriptive cross-sectional study, 38 water samples were collected from 19 sampling sites including wells and aqueducts of Sarayan, Iran, in spring and autumn seasons of 2015, and analyzed for total dissolved solids, calcium hardness, total alkalinity, water temperature, pH, Langelier Saturation Index, Ryznar Stability Index, Aggressive Index, and Puckorius Index. The results were analyzed by Excel and water stability analyzer Software and were compared with standard limits.
Results: It was found that TDS, temperature, pH, alkalinity, and hardness of water were lower than the maximum allowed limits, but calcium hardness was also lower than the optimum value for drinking water. The average value of LSI, RSI, AI, and PI in spring was 0.437±0.264, 7.25±0.368, 12.33±0.273, and 7.37±0.432, while the average values of these indices in autumn were 0.501±0.229, 7.231±0.359, 12.55±0.225, and 7.33±0.503, respectively.
Conclusion: According to corrosion indices, drinking water of Sarayan County was relative scaling. Considering the negative effects of scale-forming water on pipe diameter, and flow rate and probable economic damages, control measures must be taken to prevent scaling in water resources.
