بررسی پتانسیل خورندگی و رسوب‌گذاری آب ‌شرب چاه ها و قنوات روستاهای مجاور گسل رفسنجان در آبان و آذر سال 1392

Background and Objective: Water corrosion leads to increase in toxic metals concentration, such as arsenic, copper, lead, cadmium, zinc, nickel, iron and manganese in water. Toxic metals in water consumers cause acute health risks. Scaling water leads to economic and technical problems. Thus, The aim of this study was to investigate the corrosion and scaling potential of wells drinking water and aqueducts in rural areas adjacent to Rafsanjan fault. Materials and Methods: This cross-sectional study was performed during October to December in 2013. 120 water samples were totally taken  through grab sampling in two stages from 22 wells and 38 aqueducts in rural areas adjacent to Rafsanjan fault. The temperature, calcium hardness, alkalinity, total dissolved solids, and pH were measured. The potential of corrosion and scaling of waters were analyzed using corrosion Indexes. Data were analyzed by descriptive statistics. Results: Langelier indexes for 90 percent of wells and 92 percent  of aqueducts, were positive and 86 percent of wells and 84 percent of aqueducts of Rayznar index obtained less than 7. Aggressiveness index for 86 percent of  wells and 81 percent of aqueducts was more than 12 and 64 percent of wells and aqueducts of Pockurius index was less than 6. Conclusion:, It was realized that wells and aqueducts drinking water in rural areas adjacent to Rafsanjan fault has scaling tendency by survey of corrosion indexes. Thus, it is necessary to stop economical loss and  hygienic harms in order to maintaine water quality stabilization.
