摘要：Corrosion is a physical and chemical reaction between materials and the surrounding environment, which causes changes in the properties of the material and may lead to the financial loss of pipes, as well as other transmission and distribution facilities. In addition, corrosion may be associated with the entry of heavy metals into water sources, threatening the health of the users. The present study aimed to evaluate the corrosion and scaling potential of the drinking water sources in Neyshabur city, Iran in 2017. This descriptive, cross-sectional study was conducted on the water sources in Neyshabur city. In total, 50 samples were randomly selected from the water distribution network to evaluate the corrosion and scaling potential based on the Langelier, Ryzner, aggressive, and Pokurious indices. The mean values obtained for the Langelier, Ryzner, Aggressive, and Pokurious indices in the samples collected from the distribution network were -0.91, 9.58, 11.69, and 8.57, respectively. According to the results, the drinking water sources of Neyshabur had the potential of corrosion and could cause damage to the water supply facilities, causing long-term adverse health effects on the users. Considering the health and economic damages caused by corrosion and scaling in water facilities, the quality monitoring of water is always necessary.
