Background: Scale formation and corrosion continue to cause mild and serious problems in water dispensing systems. Althoughthere are advanced technologies available today, such problems still persist and can lead to health problems and financial damage.Objectives: To delve into this matter, the present study aimed to determine the water potential in terms of scale formation andcorrosion in the water resources of villages in the vicinity Harsin town in Iran. Furthermore, the physical and chemical qualities ofthe water were also studied.Methods: For this descriptive study, samples were prepared from ۱۹ villages during the ۸ months of the study duration. These wereanalyzed according to standard ۱۰۵۳ of Iran water standard and study institution, also calculated for Langelier, Rayzner, Puckoriusand aggressive indices for scale formation and corrosion.Results: Indices were ۰.۸۰ on Langelier, ۶.۶۸ on Rayzner, ۱۰.۹۲ on aggressiveness, and ۶.۸۵ on Puckorius calculations. Mean concentrationsof calcium, magnesium, fluoride, and ammonium were respectively ۶۳.۸ ۱۶.۸۹, ۲۱.۱ ۹.۰۸, ۰.۳ ۰.۲۶, and ۰ ۰.۰۱milligram per liter which are reasonable according to national standards.Conclusions: Findings revealed that all physical and chemical indices, and cations and anions of water samples were within areasonable range. Other parameters involved in causing hardness were also at standard levels. The water resources of Harsin townwere healthy in terms of scale formation and corrosion verification, but they still needed close attention in order to keep themwithin the current appropriate conditions with possible improvements.
