Abstract: Reuse of water in arid and semi-arid areas is unavoidable. Considerable amounts of wastewater, lack of good quality water for irrigation and require more agricultural products demands are the main causes of using unusual water. In some parts of South Tehran in the area of several acres of irrigated agricultural region of South Tehran on water from wastewater treatment plants is used for irrigation. The anomalous application and mismanagement of the water resources can cause environmental problems and affect soil and water resources. Heavy metals in the water can be a factor limiting the use of these waters. In this paper study 16 water samples were taken from Kan and Sorkhehesar Water courses and the result showed that the amount of lead in old road stations in 23 July to 22 August and 23 October to 21 November was 0.3 mg L–1 higher than Canada, China, Taiwan and Saudi Arabia standards. Also, in Saveh highway this value was 0.5 mg L–1 in 23 July to 22 August and 0.4 in 23 October to 21 November was higher than Canada, China, Taiwan and Saudi Arabia standards. Cadmium was 0.02 mg L–1 higher than Canada, the US, Iran, Tunisia and Australia and FAO standards. It is recommended that in order to educate the citizens the responsibilities of state and municipal institutions be separated in the field of implemented management strategies. Also, agencies carry out their duties regarding the creation of appropriate structures, preparation and execution of the program and the separation of pollutants from the source more carefully and with caring.
