Soil contamination is the occurrence of contaminants, either artificial or natural, above tolerable levels which cause deterioration or loss of soil functions. Soil pollution is divided into two forms: point pollution and diffuse pollution. The former refers to the specific events that cause pollution, while the latter points to low levels of contaminants over a vast area which are challenging to analyse and track.
Mishandling dangerous chemicals poses health risks to people living near polluted areas. Although various human activities influence soil pollution, it’s most common in urban areas and former industrial sites. But how can people safely dispose of contaminated soil?
Bioremediation might be the best yet the most natural approach to polluted soil disposal. It is the use of biological processes to degrade and remove contaminants from the soil. In effect, microorganisms like bacteria and fungi will rely on the contaminants as their food.
Although effective, its downfall is the complexity of the process itself. Bioremediation requires a balance among temperature, nutrients, and food for the process to work. The lack of any among the factors may lead to a prolonged cleanup drive or total failure. But again, it might be the safest process that offers little to no damage to ecosystems.
2. Soil Stabilisation
On the other hand, soil stabilisation is the chemical or mechanical modification of soil engineering properties. It is a technique that helps refine and improve soil properties. Stabilising the soil means decreasing the contaminants in it, reducing the chances of pollution in the material.
There are two ways to perform soil stabilisation: first is by changing the contaminant in the soil, making it less harmful. Another is by reducing the contaminant’s mobility, settling it in place, and preventing further spreading.
3. Chemical Oxidation
Chemical oxidation is a form of chemical decontamination where oxidants are pumped into the soil and groundwater for rapid, total contaminant degradation. Oxidation refers to eliminating one substance with another, prompting a chemical reaction that cancels out the other. In effect, the soil becomes free from its contaminants and turns into a toxic-free state in the long run.
Among the practices for disposing of contaminated soil, chemical oxidation is the most flexible approach. The solution goes deep into the surface, removing contaminants even in the most difficult-to-reach spaces underneath the topsoil. Therefore, people can assure that there will be no trace left of the harmful substance lying underground.
4. Soil Washing
Soil washing refers to the use of a liquid wash solution, removing harmful substances in the process. Although finer-grained soils, such as silts and clays, get washed away, it does not intend to kill or eliminate the pollutants. You may still need professional help for disposing of it effectively.
5. Skip Bins
The use of skip bins might be the most efficient way to eliminate contaminated soil. Keeping all the waste materials in one place is safer than letting the contaminated soil with the uncontaminated ones. They are available in multiple sizes, serving every purpose for various types of projects.
Remember that contaminated soil leads to severe consequences, especially for people coming into contact with it directly. Most of the time, children who play outdoors are the most at risk. However, adults must be careful in going near polluted dirt as it may result in adverse results and dangers linked to health.
