In this research, environmental impacts of development plan on the pollution of water resources of Khozestan province were studied. One important river passing through Khozestan is the major source of water for domestic and agricultural uses. Karon River that provides the major portion of water used in this province in the most polluted river in Khozestan province and even in the country. This river plays a crucial role in spreading microbial diseases directly or indirectly. The sources of pollution of the river may be classified into industrial wastewater, urban sewage and agricultural wastewater. All shops and markets introduce their waste materials into this river. This study tried to introduce the factors explaining pollution arising from industrial development in urban and rural areas. In order to measure the degree of pollution, BOD, COD, PH, NO3, TSS, DO and coliform tests were carried out. Samples were collected in 22 points (agricultural, industrial and urban areas) were collected for analysis every there months and the results were compared to environmental standards. Result shows that pollution of the river is above allowed levels and that the river lacks any self-refining system. Ten TSS tests out of 12 (with concentration 500 mg/l). Ten TDS tests, seven BOD tests, four FTU tests, there PH tests and all coliform tests revealed the fact that pollution in this river has exceeded allowed levels.
