Land remediation is a process where contaminants like heavy metals and hydrocarbons are removed from a land site. This process is important since it will improve the quality of the soil but there are a number of techniques you can use to deal with the problem. You should hire a professional contaminated land remediation company that has the proper equipment to clean up the soil like non-treatment and treatment options. If you want to sue your land site without exposing it to environmental risks which are also dangerous for people.
Types of Soil Remediation Techniques and Methods
When you hire a professional land remediation company the first thing you should think about is whether they have experience in the field since all toxicants should be removed. The company will have to assess the land site first so they can come up with the best solution so they can remove the contaminants. The first technique they might use is Bioremediation where they treat the soil biologically using bacterium that has aerobic and anaerobic species.
The benefit of this technique is that once all the contaminants are cleared then the bacteria will die off so there is nothing that will harm the soil or people who are on the land site. The process will more successful in soils that have constant temperatures of 70 degrees and sporadic rain for optimal temperature. If you want the process to work in colder areas then the soil should be covered and insulated until the right temperature is attained.
Another common technique is the Thermal Soil Remediation where the contaminated soil will be placed in a PTU so the contaminants and water evaporate in temperatures ranging from 650-900 degrees. The soil will then be transferred to a cooling unit that has a drill or a mixer where liquid will be added for cooling and dust control.
Once treatment is done, the treated soil will be stored in a cooling system so it will be ready for testing and continuous recycling. The company can also use Air Sparging where air is injected into the contaminated stratum so the organic vapors are forced out and treated through carbon filtering. The treatment takes time depending on various factors like permeability and pH of the soil.
Another main technique is Encapsulation which mainly focuses on separating the soil form the contaminants where they mix the polluted soil with lime or cement. Make sure the company explains what method they want to use and the benefits you gain from the whole process.
