Contaminated lands are becoming more common today, and it is mainly a result of human activities. Of course, natural pollutants also play their part, but industrial activities such as mining, manufacturing, fertiliser application, oil dumping, and inappropriate waste disposal top the list of land contaminants. More often than not, contaminated lands lose their usability and value. Hence, the need for a valid solution and treatment for contaminated soil.
Many methods have been introduced to treat affected lands, and these methods have proven very effective. However, some methods may not suit specific land sites where other methods are deemed appropriate. Of course, it is often hard to see beyond a solution that works, regardless of the side effects that follow. But it becomes crucial that you pay attention to the slightest negative impacts when treating contaminated lands. If you believe that your soil may have become contaminated as a result of a hazardous chemical spill, contact specialists in icon spill containment and environmental management services.
It is only fitting that you consider the effects of each land decontamination method before selecting your solution. But this task will be somewhat tricky if you do not know the various land treatment methods. This article will spotlight the different remediation methods for contaminated land and how to select the most appropriate.
Land Remediation Methods
- Biological Method: The biological method of treating contaminated lands has been declared the safest because side effects are minimal. It is also called bioremediation, and it has proven very efficient and suitable for most land sites. It is also pretty affordable, making it the go-to method for many landowners. It involves using biological organisms to absorb and eliminate pollutants.
- Chemical Method: The chemical treatment of contaminated soils involves inducing chemical oxidants into the soil to eliminate the pollutants in the soil and underground water. This method is equally efficient, but the oxidants are often powerful and may leave a little more effect than expected. It is also relatively cost-effective and can be used to decontaminate large land areas.
- Soil Washing: This method is exactly as the name suggests. The contaminated soil is washed with a liquid solution to remove the contamination. But unlike the previous methods that target and eliminate the pollutants, soil washing only washes away the contaminated soil. Hence, a disposal method may yet be needed to eliminate the contamination completely.
- Soil Stabilisation: Soil stabilisation is a unique decontamination method that traps pollutants instead of eliminating them. This method is only adopted for specific sites, as it can limit the land’s productivity. It functions by cutting off the pollutants and keeping them in check underground without having to rid the land of them.
What to Consider When Selecting a Land Remediation Method
Selecting the best solution for treating contaminated soils does not have to be as challenging as it seems. It only requires knowing precisely what to consider to make the right choice. Here are some tips to help you select the best solution.
- Consider what the land will be utilised for and select a fitting solution
- Consider your budget and go for a budget-friendly solution
- Some remediation methods are suitable for a large area while others are not.
- Ensure your preferred solution does not affect the land usability
- The degree of contamination should also be a decider
Pollutants can utterly damage any land and render it useless. But thanks to remediation, such lands can still be treated and put to good use. However, selecting a suitable method is critical, and this article has provided tips on choosing the correct remediation method for contaminated lands.
