Preservation of the Karoon and Dez Rivers, the fresh water resource, is of high importance in Khuzestan province with its rapid growth of population and agricultural and industrial activities. In this paper the water quality and quality conditions of four study areas are mapped, agricultural, industrial and urban pollutant sources identified, and their impact on biological, physical and chemical water quality of Karoon River examined. Twenty five quality monitoring stations were established to determine the pollution load to the Karoon and Dez Rivers. The analysis shows that wastewater discharge has different impacts on chemical and biological water quality in the four study areas, in both the short and long term.
