Soil contamination, which happens because industrial activities and pollution negatively alters the land’s components, is most common in the areas surrounding oil plants, mining sites, and factories. Due to the health risks it poses, it is imperative that the contaminated area be cleaned thoroughly.
The use of advanced equipment and the skills needed to handle chemicals in a potentially hazardous environment, however, makes purifying contaminated soil a task best left to professionals.
There are a various ways to properly eliminate oil residue, cyanides, heavy metals, and pesticides from the soil. The Facebook posts by Enviro Care Inc., for example, show some of them. Here are more soil remediation methods.
Excavating & Dredging
Excavating and dredging is the process of extracting the contaminated soil and transferring it into a separate landfill. This is one of the most common and simplest methods of soil remediation.
Soil washing helps reduce the disposal of toxic chemicals. It involves sorting the contaminated land into rocks, gravels, and sands. The classification helps professionals isolate the contaminants as most contaminants cling to the finer soil. With the rocks and gravel materials clean after washing, specialists can concentrate on remediating the finer sand particles.
Pumping & Treating
This method involves pumping the soil, as well as the contaminated ground water. The mixture then goes through a filtering system that will remove the chemicals. Remediation professionals would then pump the water and soil back into the area after the purification process.
Treating the contaminated soil through chemical oxidation is a more advanced approach to soil remediation. This process oxidizes the contaminants in order to reduce their concentration in the soil. Different factors determine whether or not a site is suitable for this kind of method.
Thermal desorption uses intense heat to remove the moisture and organic matter of the contaminated soil. This type of soil remediation is ideal when dealing with oil and diesel spills and other hydrocarbon contaminations.
Soil remediation is necessary to restore the infected area’s land fertility and structure. Its many processes ensure that each situation will have a corresponding method.
