The study of hydrogeochemical and assessment of water quality of Shavour River, Shush, Khuzestan province

Surface waters usually" because of contact with different geological formations, relationship with groundwater and surface water resources are associated with highly variable chemical composition. threaten the risk of contamination of water resources. The Shavour River with a long of 90 km in the North West province of Khuzestan is located between the two Karkheh and Dez Rivers. In this study, understanding of water quality of Shavour River based on different parameters of food, agriculture, as well as its environmental impacts are considered. The case study based on available data on the two water year 90-92 on Shavour Bridge station using graphical methods such as Piper diagrams, Scholler, Wilcox comparing with international standards for water quality analysis was conducted. The results showed that, according to the Wilcox diagram of the river's water is of C3S1class and is pretty good for consumption and agriculture. The Scholler diagram showed that all of the river's water cations and anions are fairly good and the ranges are good and drinking.
