soil washing

Soil washing is a technique used to clean contaminated soil by mixing it with water and specific solvents or additives. This process helps to extract pollutants, such as heavy metals or chemicals, from the soil particles. The mixture is then separated, allowing clean soil to be restored or reused, while contaminants are collected for proper disposal. Soil washing is often employed in environmental cleanup projects, making it an effective method for rehabilitating polluted sites and improving soil health.
