Soil remediation is a branch of environmental remediation process. It is a terminology that is used for different techniques that are used to purify and revitalize the soil. The problems in the soil can be caused by contamination of substances which could be causing the undesirable effect or can have negative effects in the future. Soil remediation concentrates in reducing any contaminant concentration that may be present in the soil to lower the levels and make land more suitable for use without taking any environmental risk. Most people are not aware of remediation as a process of purifying and revitalizing the top soil. It is good to the environment since a more productive and healthy land will be achieved. You will need a soil remediation expert for a full -scale property or home improvement.
Different methods can be used to deal and lower the soil contamination. Some are more effective than others. There are thing that you should know when selecting the effective method. You need to have in mind that the method you use will have an effect on the living organism in the surrounding. You should know the nature of soil contamination and the success the activity is expected achieve. To eliminate different soil contaminants, you need to conduct multiple soil remediation processes.
Top soil remediation can be put into three categories. The soil need to undergo the treatment in which the aim is to reduce the level of contaminant to a safe level. It is accompanied by physical removal aimed at removing the concentrations entirely. Lastly it’s the stabilization process where the contaminants are combined with other chemical to remove the risk of the contaminants but this takes time to get the results. This method involves gathering the volatile material in the soil and inhibiting their mobility. This is achieved because a chemical stable material is created within the soil which leads to this effect. Lime is used to solidify these top soil contaminants.
The remediation can also be achieved by getting rid of underground water that may be contaminated and then purifying it. The process is called pump and treat. The contaminants can be filtered by extracting the soil and then returning it to its initial place.
The main process that is widely used in soil remediation is excavation and dredging. A landfill of contaminated soil is set aside and it is extracted using current technology. Once the contaminated soil as been extracted, it is transported to the landfill and purified soil is used to replace the area in which the contaminated soil was extracted.
Due to the advancement in new technologies, there are more effective methods that are being developed. The soil remediation efforts are being planned at the national government levels. The aim is to eradicate all harmful contaminants in the soil to make it appropriate for farming, dwelling and animal habitat. The government issues orders on the approach to be used in soil remediation. The directives are based on the soil remediation standards in the particular state. The environmental ministries assist in any effort geared towards soil remediation
