چکیده

arrival oil pollution , chemical features of soil influence and change. According to several oil fields in Iran, including mining centers (offshore drilling), desalination facilities, transfer stations and oil refineries , Whereas Cleanup of petroleum contaminated soils is a complex and costly process , so achievement to model the effects of oil pollution and waste resulting from them, Appropriate options for managing wastewater discharges, oil can prevent infection presented. So far, studies on the variation of soil parameters and the impact of waste oil and crude oil are taken. In this research , effects of waste from crude oil storage tanks on pH , TDS , OC and TPHs , in seven stations including four polluted stations , two semi polluted stations and one control area in two period of sampling (March and June) , was tested. The results indicate that significant changes in these parameters because of waste oil.TDS in polluted samples was 480% increased because of the high amount of TDS in wastewater tanks and EC is also looking up. Organic carbon is also 740% increased. It is affected from the organic compounds presented in crude oil. TPHs have a very large increase because of existence oil hydrocarbons in effluent. The overall results show the impact of wastewater on soil chemical features.
