Soil remediation is the process of restoring contaminated soil to its original state or to a state where it is safe for human health and the environment. This typically involves removing or neutralizing pollutants in the soil through techniques such as excavation, bioremediation, phytoremediation, soil washing, and chemical treatment. Soil remediation is important for cleaning up sites contaminated by activities such as industrial processes, agriculture, and waste disposal, in order to protect human health and prevent further environmental damage.
