Contaminated Soil Remediation

Topsoil Remediation Techniques And Methods

Soil remediation, also referred to as soil washing, is primarily a combination of processes that are designed to remove the contaminants, including hydrocarbons, such as fuel residue and petroleum, pesticides, volatiles, heavy metals, semi-volatiles, cyanides, and creosote from the soil. Soil remediation is important to ensure that the soil is clean and maintains its high quality. If the soil, air, and water are clean it ultimately improves the cultivation process.

Irrespective of the fact that most people are not aware of soil remediation as a technique to revitalize and purify the topsoil, it is also important to the environment as it helps in making the land productive and healthy. In terms of landscaping, the soil remediation process involves different procedures, which help in renewing and purifying the soil. It is simply about balancing the pH levels, composts and minerals in the soil.

All the above-mentioned procedures are imperative in making the soil healthy, but it is important to note that soil remediation needs to done before the land is tiled or landscaped. This essentially helps in removing the contaminants and pollutants from the soil. Some of the popular soil remediation techniques include soil excavation, vapor extraction, and chemical oxidation.
The most common technique used for contaminated soil remediation is excavation. It is essential to remove the contaminated soil and excavation is the simplest and most effective form of soil remediation. Excavation is a feasible method designed to address all issues related to human health immediately. Excavation restores the topsoil and can be easily followed by anyone who is looking for contaminated soil remediation.

Apart from this, another top technique to address this issue is extraction and topsoil vapor. It helps people to restore and repair the ecosystem while purifying the air. However, this technique ‘draws off’ a substantial amount of capricious constituents in the contaminated soils. Regardless, it is a simple technique in which a vacuum is created near the contaminated area to extract significant volatile elements from the soil. Many people refer this technique as soil venting and vacuum extraction.
Many people make use of soil stabilization as a contaminated soil remediation technique. Unlike the above two mentioned techniques, soil stabilization uses chemical elements – thus, it takes time to reflect the impact on contaminated soils. The chemical reagents are used to ensure encapsulation of volatile elements in the soil as the component reduces their mobility. It is believed that the chemicals used in soil stabilization forms chemically stable material in the contaminated soil make use of lime, which is one of the most effective reagents to solidify contaminants.

Last, but not the least, chemical oxidation along with pump and treat remediation technique. The two different techniques are effective and guarantees immediate results. In chemical oxidation, oxidants are injected in the soil that transforms the contaminated soil elements harmless. On the other hand, the pump and treat technique pumps the contaminated water out of the ground so that it can be treated later.
