Ex Situ Bioremediation And Landfarming

This process involves excavating the contaminated soil, piling it in biotreatment cells, and periodically turning it over to aerate the water (U.S. EPA 1993a). The moisture, heat, nutrients, oxygen, and pH are usually controlled in the process. In addition, volatile emissions as well as leachate from the biotreatment cells should be controlled. The technology is effective for soils contaminated with fuel hydrocarbons. Also, the contaminants can be completely destroyed and the soil reused.
