Decontaminating the Environment: 4 Types of Soil Remediation Technologies to Explore

By  | 

Everyone wants to do their part to save the Earth. Real change needs to be implemented today to make sure the planet is strong and sustainable for the future generations.

Soil remediation is basically washing the dirt or soil to rid it of harmful contaminations. Healthy soil is the foundation for growing better crops as well as providing a better environment for building upon.

One of the ways large industries is making the planet a better place is by taking care of the soil before they begin to build new structures or plant new crops. You can learn more about thermal remediation services here.

Below are 4 types of soil remediation technologies worth exploring.

  1. Thermal Soil Remediation

This type of soil remediation removes specific types of soil contaminates. The use of extremely high temperatures is what takes the contaminates out of the soil. This is touted as one of the best ways to remove hydrocarbon or water compound pollutants as well as petroleum and oils.

This is basically “baking” the soil until all the toxins are removed. The contaminated soil is captured in a safe container for disposal after they have cooled and are safe to remove from the site. The remaining dirt is then ready for further testing and recycling into viable ground for what is needed.

  1. Bioremediation

This soil remediation technique uses biological mechanisms instead of a mechanical method. The unsafe soil is introduced to a to an anaerobic and aerobic bacterium which will feed off the exact type of toxins in the soil.

This is similar to how a yeast infection feeds on sugar. The bacteria will die off after their supply is depleted. This process works best with dirt that is above 70° F with only sporadic rain. This method could be used in colder climates; however, the soil would need to be covered and would take longer to clear the toxins.

  1. Air Sparging

This method is best in soil that has been contaminated by vapors or gases of a toxic nature. The best and only way this remediation will work is if it is applied directly to the soil, not extracted soil.

Large amounts of pressurized air are injected into groundwater or soil to remove the organic compounds that are volatile. This is one of the most common soil remediation techniques as it is easier and costs less.

  1. Encapsulation

Encapsulation remediation is different than the other methods because it does not remove the toxins from the soil, but rather quarantines them so that they cannot spread to other areas. This is done by mixing the contaminated soil with concrete, cement, or lime.    

This method will prevent other soils, those that are not full of contaminants, from coming in contact with the toxic soil. This, like all the other methods, is effective, but the new soil cannot be used for crop planting.

From large companies to individuals and small families, there is plenty we can do to save the planet. Soil remediation is but one of the many steps being implemented to save and preserve our planet.
