A variety of technologies are currently available to treat soil contaminated with hazardous materials including excavation and containment in secured landfills vapour extraction stabilization and solidification soil flushing soil washing solvent extraction thermal desorption vitrification and incineration us environmental protection agency 1988 russell 1992. Agricultural wastes such as wheat bran and swine wastewater were used for bioremediation of oil contaminated soil two optimised strains that could degrade oil efficiently were selected the. Bioremediation naturally occurs or helps to enhance the fertilizers and microbes similarly microorganisms present in the soil first identify the oil and its components namely energy and carbon through biosurfactants and bio emulsifiers poor solubility and binding of high molecular weight hydrocarbons make these carcinogenic compounds inaccessible to microorganisms upgrading surfactants . For the treatment of contaminated soil physiochemical and biological treatment is used the physicochemical treatments are incineration thermal desorption coker cement kiln solvent extraction and land filling etc
