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. When soil becomes contaminated, it can negatively affect plant growth, water quality, and the overall health of ecosystems. Cleaning up contaminated soil is essential for protecting the environment and public health. Remediation techniques, such as soil washing or bioremediation, are often used to remove or neutralize pollutants. Addressing contaminated soil is crucial for ensuring safe land use and maintaining the balance of natural habitats, benefiting both humans and wildlife.
