In situ treatment such as leaching with water, heating, injection of compounds that dissolve the organic contaminants, or treating to soil in a way that locks up the pollutants so that they can be pumped out of the system, is used to remove some of the problem elements.
Can polluted soil be cleaned and restored?
A solution to the problem of soil contamination is soil remediation. … In short, the goal of the process is to restore the soil to its natural, pollution-free state. Traditionally, there are three main soil remediation technologies: soil washing, bioremediation and thermal desorption.

Can lead be removed from soil?
Lower Soil pH – Lead can be extracted easier under acidic conditions. If you want to facilitate lead being drawn out of soil by plants, then make your soil more acidic. You can do this by adding more acidic compost or amendments (sulphur, leaf mold, coffee grounds, pine needles) to your soil.
Do sunflowers clean the soil?
