This video will discuss the pros and cons of five different soil remediation methods. To start, soil remediation is the purifying of the soil of any chemicals that can be harmful to the surrounding environments. It is the process that returns the soil to the pollutant-free substance that it was originally. It protects the population around it. This video will show a few methods of site remediation.
The five methods of soil remediation are discussed as followed: soil vapor extraction, electrical resistance heating, chemical oxidation, excavation, and using institutional controls.
Looking at soil vapor extraction, that process is done by removing contamination as vapor by using a powerful vacuum that connects to extraction wells. This method tends to be low maintenance and can be used at active businesses. It is also quite cost-effective compared to other methods. A big con of this method is that it is very limited to the types of soil it can treat. It is limited to coarse soils such as sand and gravel. Continue watching to see how the remaining four remediations methods compare.
