Contaminated soil refers to soil that has been polluted by harmful substances, such as chemicals, heavy metals, or waste materials. This pollution can occur from various sources, including industrial activities, agricultural practices, and improper waste disposal. Contaminated soil can pose risks to human health, plants, and wildlife. Cleaning up contaminated soil is essential for restoring the environment and ensuring safety. Techniques like soil washing, bioremediation, and phytoremediation are often used to remove or neutralize pollutants. Addressing soil contamination is crucial for sustainable land use and protecting ecosystems, as well as for communities living near affected areas.
