Abstract

In industrial areas leakage of oil and it’s penetration into the soil can change the engineering properties of soil as well as cause environmental disaster. Also, recovering the contaminated sites into their natural state and reuse that contaminated material after treatment in the construction field needs remediation techniques which approach environmental friendly as well as geotechically suitable. This review article is an examination of the behaviour of various oil-contaminated soils on the engineering properties as well as physical, chemical and biological properties of soil. It also includes various remediation methods and shows a brief review about bioremediation method and also highlighted a bioremediation method as a sustainable, effective, low cost, and no harmful effect method. The article shows that the, crude oil can change various engineering properties such as optimum moisture content, maximum dry density, shear and compressive strength, settlement and permeability of soil as compared to natural soil. But the bioremediation technique helps in a positive manner to enhancing soil properties and also recover the contaminated soil in to their natural state. The various measurement technique of total petroleum hydrocarbon of crude oil contaminated soil also mentioned in this article. Generally, the application of bio-treated soil as utilized in the construction of liners, road construction, manufacturing portland cement, and erosion control projects. Keywords: Oil-contamination, Bioremediation, Soil properties, Engineering properties, Total petroleum hydrocarbon (TPH).
