Soil remediation is the process of purifying and revitalizing soil as part of environmental remediation efforts. Many countries, including the UK, Australia, Canada, and the US, are engaged in land reclamation. Methods include excavation, dredging, pump and treat, and new technologies. Remediation restores ecological balance and supports efforts to clean air and water.
Soil remediation is the collective term for various strategies used to purify and revitalize soil. This soil cleaning process is part of a larger effort known as environmental remediation, which may also include efforts to purify the air and other wise remedies to repair the damage done to the ecological balance of the planet. Many countries are actively engaged in some type of land reclamation, including the UK, Australia, Canada and the US.
In most cases, efforts to clean up soil are structured at the national government level. In the United States, the approach to soil remediation is based on guidelines issued by the Environmental Protection Agency (EPA). In Canada, the Cabinet of Ministers of the Environment provides support to each province’s collective efforts to conduct remediation and remediation actions relevant to each geographic location’s environmental challenges. Currently, the countries involved in the European Union are also creating standards that will serve as the basis for organized remediation strategies.
There are several methods currently employed in the soil contamination treatment process. Often, selecting the most effective strategy will depend on the nature of the contamination, the impact of the method on surrounding wildlife or humans living nearby, and the degree of success that can be expected from the land remediation effort. It is not unusual for a given tract of land to undergo more than one remediation operation to cope with the presence of multiple contaminants.
Among the processes used in land reclamation, excavation and dredging are among the most common. This process involves extracting contaminated and unrecoverable soil using current technology and transporting it to a landfill intended for this purpose. Purified soil is often used to fill in the area where the mining took place.
Soil remediation is sometimes done using a process known as a pump and treat. Essentially, this approach involves removing the contaminated groundwater, then using various methods to purify the extracted liquid. While the water is purified, the soil is also dug out and filtered to remove various contaminants, then returned to its original location. The purified water is returned to the purified soil, effectively restoring the ecological balance of the area.
As technology advances, new methods are being developed to remediate contaminated soil. This will purify the land and allow the area to be used for growing food, creating nature reserves or even allowing humans to safely build homes or commercial buildings in the area. At the same time, ridding the soil of dangerous contaminants will support efforts to clean the air and water, making the world a safer place for all living things.
