The Sivand River Originates from the southern heights of Eghlid City and joins Kor River at the Khan Bridge, and eventually, pours into Tashk and Bakhtegan Lake after 310 Kms. In this study, we were able to estimate quantity of each of the pollutant sources and by dividing amounts of pollutant load to total load we calculated participation of each pollutant. The study, shows that Sivand River is mostly affected by the residential discharges and many food processing industries such as Yek-O-Yek factory along side the river and the municipal waste discharge from the Marvdasht City.
