Active remediation is a form of environmental remediation that involves using direct action techniques to remove, contain, or neutralize pollutants from a contaminated site.
A closure document, issued by a state environmental agency, indicates the successful remediation of a contaminated site, ensuring no further action or legal liability is required for environmental cleanup.
Ex-Situ processes involve offsite handling and treatment of contaminated material, distinct from the property where contamination exists. These methods are often employed in environmental remediation projects.
