Conduct online research on the classes of soil remediation: in-situ and ex-situ. Briefly describe your findings.

In in-situ remediation, there is no excavation of the contaminated soil. This remediation is an economical way of cleaning up. However, it takes a long time for the treatment to be effective. In addition, the treatment is not uniform because of variability within soil and difficulty in monitoring remediation progress.

Ex-situ remediation involves excavating a contaminated area. In this method, the soil is either treated on the same site or transported to a remote site for cleaning. This type of remediation is complex and expensive, but very effective. It involves the following:

homogenization of the contaminated soil before treatment

monitoring to ensure that the soil is cleaned to the required level

Soil remediation is the process of making the soil pure and free of contamination which affect the health of the soil and the organisms that depend on it for their survival.

The two classes of soil remediation are:

In-situ
Ex-situ

In-situ has to do with the treatment of the soil by removing the affected soil so that other parts of the soil does not get contaminated.

Ex-situ method is the process which involves taking the affected soil to an external site for decontamination which ensures that the other parts are not affected.
