With notice to publish records, more than 01 percents of world earth is exposed to pollution with chemical materials. When pollution composition is poured on soil surface or is added to soil, some physical and chemical phenomena with some soil features are adequate on soil fate and environment. For example, about oil hydrocarbon these pollution composition maybe evaporate or they exit with spontaneous oxidation, thermal, light and bio decomposition from soil. In the other hand there is possibility of this composition transmission in soil and arrive to ground water surface. For mineral polluted composition is possible this reaction in soil: 0- surface adsorption with soil ingredient 0- exclusion of composition with same electrical capacity with soil ingredient 3- breakup and sediment reactions and 4- decomposition and degradation reactions. In any way presence of this polluted composition in soil can damage to soil quality and healthy and finally can influence on human health. In this study is evaluated new process for pollution elimination from soil and then is evaluated the advantages and disadvantages of any method. Evaluation results are shown that between these methods, physical purge process has special place. Advantages of this process in comparing with present purges methods are: simplicity system design and its implementation, requirement to short time for purge (6 month to 0 years with notice to qualification of present pollution), very slightly cost than another purge methods (31 to 61 dollars per purge of 0 ton polluted soil), increasing in purge destroying of organic composition in areas with low bio decomposition, requirement to low equipments and facilities and additive to soil and low lateral effects on environment.
