A Comprehensive Guide About In-situ Soil Remediation

Author : Byrne Resources Group | Published On : 10 Jun 2021

Soil contamination is a pervasive issue these days. It has a more powerful existence than you can ever imagine in agricultural areas, residential spaces, and industrial sites. It is spreading its roots quickly and depriving the soil of its fertility.  

In such scenarios, soil remediation methods come to the rescue. And one of the effective methods is in-situ soil remediation. In situ means in place. The soil is purified and the contaminants are discarded from the soil in this method. 

 

This article will delve into the methods of in-situ soil remediation which are usually followed by the best plants for soil remediation

The types of in-situ remediation process are discussed below: 

 

Chemical oxidation:

The chemical oxidation process involves mixing specific chemical oxidants with contaminated soil. The chemical oxidants start reacting with the contaminants in the soil and make less detrimental compounds in the procedure. 

The common combinations utilized are Fenton's reagent, hydrogen peroxide in this type of chemical oxidation process. The iron agents are inserted into the soil after hydrogen peroxide is added into the same soil. Hydrogen peroxide is very useful to break down petroleum contaminants. To amp up the effects, iron is mixed in the Fenton reagent. 

 

Augmented microbial enhancement

 

The augmented microbial enhancement introduces certain microbial organisms in the soil. These microbes are efficient enough to break down specific compounds or chemicals by natural digestive processes. 

 

One of the examples of this procedure is the use of microbes in order to break down cadmium contaminants. Cadmium gets into the soil with fertilizers, sewage sludge and aerial disposition. To withdraw cadmium contamination microbes are injected into the soil. With the passage of time, microbes break the cadmium down into less harmful components. 

 

Aeration

 

This method aids to remediate soil in settings where there is a presence of hydrocarbon contamination. Hydrocarbons are usually linked with petroleum product contamination such as gas or oil. When the contaminants are buried deep, they become intact. 

 

However, when oxygen interacts with the hydrocarbons, it can stimulate and enhance the natural biodegradation of the contaminants. This method is carried out in some other methods. One of these is ground aeration where the soil is dug and is brought in contact with air. The other method is to insert oxygen deep into the soil with bioventing.

 

Soil Blending

 

Soil blending is one of the most effective techniques of soil remediation plans. The method can reduce the concentration of contaminants in the soil. This method is used in areas where agricultural pesticides are the principal contaminant. Testing reflects the depth to which the contaminants are remediated. 

 

These methods are reliable and effective enough to get rid of contaminants in the soil.
