Natural processes like weathering and erosion are not considered primary sources of soil pollution, as they occur naturally and are not caused by human activities.

Soil pollution control technologies aim to reduce the levels of pollutants in the soil, rather than completely eliminating them, as complete elimination may not be feasible or practical.

Soil Excavation and Replacement involves physically removing the contaminated soil and replacing it with clean soil, thereby reducing the levels of pollutants in the affected area.

Bioremediation utilizes microorganisms to degrade and remove pollutants from soil, converting them into less harmful or non-toxic substances.

Phytoremediation employs plants to absorb and accumulate pollutants from soil through their roots and stems, thereby reducing the levels of contamination.

Soil Flushing involves the application of water or solvents to dissolve and remove contaminants from soil, transporting them to a treatment system for further processing.

Soil Stabilization aims to immobilize and reduce the mobility of pollutants in soil, preventing their migration and potential harm to human health and the environment.

Soil Vapor Extraction involves the application of a vacuum to extract and remove VOCs from soil, preventing their migration and potential harm to human health and the environment.

Permeable Reactive Barriers are constructed underground to intercept and remove pollutants from groundwater, preventing their migration and potential harm to human health and the environment.

Thermal Desorption involves the application of heat to volatilize and remove contaminants from soil, converting them into a vapor that can be captured and treated.

Electrokinetic Remediation utilizes electrical current to induce the movement of contaminants in soil, facilitating their removal and treatment.

Surfactant-Enhanced Remediation involves the use of surfactants to reduce the surface tension of contaminants, enhancing their solubility and facilitating their removal from soil.

Bioremediation utilizes microorganisms to break down and convert hazardous waste into less harmful substances, reducing their toxicity and environmental impact.

Phytoremediation employs plants to absorb and accumulate heavy metals from soil through their roots and stems, thereby reducing the levels of contamination.

Permeable Reactive Barriers are constructed underground to intercept and remove contaminants from groundwater, preventing their migration and potential harm to human health and the environment.
