Environmental remediation is the cleanup of hazardous substances dealing with the removal, treatment and containment of pollution or contaminants from environmental media such as soil, groundwater, sediment. [1] Remediation may be required by regulations before development of land revitalization projects.
Remedial Action is often enacted through ‘Remedial Action Plans’ (RAPs) of three or more stages. For example, one North American river protection scheme drew up a plan that identified environmental problems and sources of pollution, evaluated and carried out actions to restore the area, and confirmed that these actions had been effective [3]
Sustainable Remediation is a term adopted internationally and encompasses sustainable approaches, as described by the Brundtland Report, to the investigation, assessment and management (including institutional controls) of potentially contaminated land and groundwater.

Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]
Physical Techniques in Remediation Soil washing is a common method of remediation that has been well studied. It is most effective when used as a pair with other techniques like advanced oxidation or phytoremediation. [ 28 ]
