Abstract
The main purpose of this research was to investigate the water quality of Zarrinehrood and Siminehrood rivers for the year 2018 and in 13 and 6 stations of the two rivers, respectively. For this purpose, the unpublished data of Na+, Cl, SO4, TDS, pH, CO3, HCO, EC, Ca, Mg and SAR parameters from both rivers were used and presented in this paper. Graphical methods were used to determine the water quality of the rivers for various human uses based on drinking and agricultural standards, and to determine the water quality in terms of sustainability, Langelier, Ryznar and Pukorius indices were used. Also, the water quality conditions of the studied rivers were compared and studied with the national standards of Iran (1053), the World Health Organization, the United States, the European Union, and the water quality standards of Iran of the Environmental Protection Organization. The results indicate that the type and facies of water is calcium bicarbonate in study stations and water quality of most stations are suitable for drinking and agricultural usages. The SAR value in Shirin-Kond station is 1.51 mEq/L and the EC value is 1144 mmho/cm and its water quality is in class C3-S1 that can be used for agricultural purposes. According to the Results, water quality of studied stations is corrosive for industrial uses.
