Different methods of soil remediation

August 3, 2020 6:24 pm


Also known as soil washing, soil remediation is the process used for soil decontamination. A healthy soil is far better for growing vegetation, as well as contributing to clean air and ground water. There are a number of different processes for the remediation of soil, each of which uses a different technique to remove contaminants from the soil. Here are a few:

Thermal method

This is a technique that eliminates certain contaminants that are more effectively removed from soil with extreme temperatures. This method is usually reserved for land which is contaminated with polluted water or with hydrocarbons like oil or petrol. Normally, this occurs in an oven with a conveyor belt. Basically, the way it works is by baking the soil causing the contaminates to evaporate.

This process is somewhat different from other techniques, since most of remediation uses filtering to remove contaminants from the soil; encapsulation ensures they cannot spread further. This is similar to a medical quarantine. Instead of treating diseases by giving patients antibiotics or retroviral drugs to combat the disease, the patient is isolated to prevent contagion from spreading further. A similar measure is taken with the contaminated soil.

Air Sparging

Air Sparging is used when the soil has been damaged by harmful gases or vapours. However, it differs from other methods of remediation as it should be applied directly to the soil rather than soil that has been extracted for treatment. The process involves injecting high amounts of pressurized air into the soil or groundwater contamination, removing volatile organic compounds with a carbon filtration system.
