Soil washing is a remediation technique used to clean contaminated soil. It involves the use of water, often combined with chemical additives, to remove pollutants from the soil. The process separates contaminants from the soil particles, allowing for the recovery of clean soil and the removal of hazardous materials. This method is particularly effective for heavy metals and organic pollutants. After washing, the treated soil can often be reused, reducing the need for disposal. Soil washing is commonly applied in areas affected by industrial activities, making it an important tool in environmental cleanup efforts.
