AbstractThe collect and reuse at wastewater and swage in agriculture natural resources and green space areimportant ways to protect water resources and the environment The harmful and poisonous impacts ofthe wastewater reuse such as heavy metal on human health and soil should be seriously considered Theaim of study is to investigate the impact of wastewater of ZOBAHAN factory on some soil propertiescultivated with tree species Five irrigation treatments well water 25 water 75 wastewater 50 water 50 wastewater 75 water 25 wastewater and 100 wastewater with four tree species Cupressus arizonica Morus alba Pinus eldarica Eucalyptus camalddulensis and at three depths organic matter and CEC were measured at 0 10 cm depth Zn Ni Cu Pb Cd Cl and Hco3 at 2 depths of0 10 and 10 30 cm and Na K Mg Ca SAR ECe and PH at 0 10 10 30 and 30 60 cm were analyzedby the use of random blocks methods factorial split for 3 and 2 depths and split plot for 1 depth Theresults showed that there is no significant difference between heavy metal in different treatments and themaximum values were observed for 100 wastewater and the minimum for control Treatment wellwater The comparison between soil heavy metals before and after irrigation treatment showed thatZOBAHAN factor s wastewater increases the soil heavy metals However the concentrations of theelement are within standard limitation except for cadmium There is also significant difference betweenECe SAR and PH between different treatments in which control treatment well water has the highestand wastewater treatment has the lowest ECe and SAR In comparison between different tree species thesoil planted with mulberry has a highest concentration of Zn Cu and Pb There is also significantlydifferent between Zn Cu and Cd in depths deeper than 10 30 cm Also the comparison between Cl ECeand SAR for different depths showed significant difference such that ECe and Cl have higherconcentrations in surface soil and decreased in deeper parts Increasing in wastewater volume organicmatter increased such that the wastewater treatment has the highest organic mater concentration Generally this study showed that the wastewater treatment will result in better soil condition for plantsas it decrease salinity and increases the organic matter Based on the concentration of heavy metals andsalinity and to reduce the poisonous impacts we can choose the best water and wastewater treatment forplanting According to these results treatment no 3 1 1 water to wastewater ratio is the best irrigationtreatment
