Remediation technologies are methods used to clean up contaminated environments, particularly soil and groundwater. These technologies aim to remove or neutralize pollutants, making the area safe for human health and the ecosystem. Common techniques include bioremediation, which uses microorganisms to break down contaminants, and chemical oxidation, which involves adding chemicals to transform harmful substances into less toxic forms. Another approach is phytoremediation, where plants are used to absorb or stabilize pollutants from the soil. Additionally, pump-and-treat systems extract contaminated water, treat it, and then return it to the environment. These technologies play a crucial role in environmental protection and restoration efforts.
