Abstract

Corrosion and scaling in drinking water sources can lead to economic and health damages. These processes produce by-products in distribution systems, reduce chemical water quality, and are the cause of health issues among consumers. The aim of this study was to evaluate the corrosion and scaling potential of water supply sources of Marivan villages, Iran. In total, 106 water samples were collected through grab sampling from 64 wells and 42 springs in Marivan villages. The values of the Langelier saturation index (LSI), Ryznar stability index (RSI), Aggressive index (AI), and Puckorius index (PI) were calculated using parameters such as temperature, calcium hardness, total alkalinity (TA), total dissolved solids (TDS), and pH according to the last edition of the standard methods. Based on the RSI, 3% of the springs and 9% of the wells were in stable condition, 97% of the springs were corrosive and 90% of the wells had scale forming potential. The LSI was positive for 57% of the springs and 78% of the wells. The AI value of 40% of the springs and 64% of the wells was higher than 12 and the PI value was lower than 6 for all the springs and wells. The results of this study indicated that most of the springs were corrosive and a few of them had scale-forming potential. It was also found that the wells had scaling tendency. Thus, routine monitoring of the sources is necessary to control corrosion and scaling and maintain water quality.
