Soil remediation is the process of cleaning up contaminated soil to restore it to a safe and usable condition. This contamination can come from various sources, such as industrial activities, agricultural chemicals, or waste disposal. Techniques used in soil remediation include excavation, bioremediation, and chemical treatment, depending on the type and extent of contamination. The goal of soil remediation is to reduce harmful substances to acceptable levels, making the land safe for plants, animals, and humans. Successful remediation can lead to the revitalization of brownfields and other contaminated sites, promoting environmental health and community development.
