Ex-situ bioremediation
WebEx-situ bioremediation occurs after contaminated soils are excavated. It can be expensive, mostly due to the cost of excavation and transportation of the soil. It can also disrupt the site and requires a good deal of space. Ex-situ bioremediation is usually more successful than in-situ bioremediation. WebEx situ bioremediation approaches include use of bioreactors, landfarming, and biopiles. In the use of a bioreactor, contaminated soil is mixed with water and nutrients and the mixture is agitated by a mechanical bioreactor to stimulate action of microorganisms.
