Soil decontamination is the process of removing pollutants and harmful substances from the soil. This is important for restoring land that has been affected by industrial activities, agricultural chemicals, or waste disposal. Techniques such as bioremediation, where microorganisms break down contaminants, and excavation, where contaminated soil is removed, are commonly used. Effective soil decontamination helps protect the environment and public health. Clean soil supports plant growth, improves water quality, and enhances biodiversity. By addressing soil contamination, communities can ensure safer living conditions and promote sustainable land use practices.
