Physical REMEDIATION technique is one of the primary mechanisms for REMEDIATION of surface contaminated soils by improving the conditions for soil aero microorganism activities. In this study, the ability of physical REMEDIATION technique for REMEDIATION of a petroleum contaminated calcareous soil (Typic Calciargids) with three petroleum contamination levels was evaluated. Contamination levels were consisted of Cx (0: 1 w/w, uncontaminated: contaminated soil), C1 (1: 1 w/w, uncontaminated: contaminated soil) and C2 (1: 3 w/w, uncontaminated: contaminated soil). Results showed that the soil microbial activity was increased at all contamination levels due to physical REMEDIATION processes as compared to the control (without physical REMEDIATION processes). The Co2 evolution due to soil microbial respiration in the C1, C2, and Cx levels was about 19, 25, and 20% more than that in the control, respectively. The most reduction value in the total petroleum hydrocarbon concentration (TPH) was observed in the Cx level at the end of experiment. There was about 52% of reduction in the TPH-contents in the Cx level in comparison with the control which was only 21%. Furthermore, TPH-concentration in the C1 and C2 levels was reduced about 21 and 24% more than that in the control, respectively. According to the results of this study, it appears that the physical REMEDIATION processes (aeration and providing optimal moisture) have an impressive role on intensifying the soil microbial activity and elimination of petroleum contaminants from soil. Therefore, the physical REMEDIATION technique can be investigated as an effective and financial method with low side effects on environment for REMEDIATION of petroleum compounds from soil.
