In this study, the use of backwash, extracted from city waste from Tehran's Kahrizakareawasinvestigated in agricultural applications as well as in eco system applications. The purpose of thisresearch was to definethe quality of qualitative and quantitative parameters to measure the output ofleachate treatment plant Arad Kooh(Kahrizak Tehran) in order to reuse it for agricultural use anddischarge to surface water. This research is based on a standard method 2005,ASTAM 2009/1102/1101& DIN 2008. In all, the resultsindicated that as far as the following seven parameters are concerned, thewaste backwash at Aradkooh meets theIranian eco system standards (those seven parameters being:PH, EC, zinc, phosphate, nitrate <only for dumping into shallow waters>, total coliform level and theopacity level). In addition, as far the following sixparameters are concerned, the said backwash meetsthe standards of the International Health Organization (these six being PH, zinc, TDS, nitrate and totalcoliform). Finally, as far as the following seven parameters are concerned, Aradkooh's backwashmeets the standards of the International Wheat and Groceries Organization (these parameters being:PH, zinc, dissolved solids, ammonia, nitrate and total coliforms). However,the study showed that thelevels of the heavy metals of cadmium and lead are above the stated standards of the following threeorganizations: the Iranian eco System Organization, the International Health Organization and theInternational Wheat and Groceries Organization. The biochemical and chemical oxygen demandparameters have been restricted for irrigation consumption because of they are assumed as pollution.So this backwash is pollutedand it is not useful for irrigation consumption. If we want to use thisbackwash for irrigation consumption, we have to treat it to reduce that mentioned pollution parametersin accordance to the Iranian eco system standards following International Health Organization andInternational Wheat and Groceries Organization.
