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 the practice of considering the effects of implementing an environmental cleanup and incorporating options to minimize the footprint of the cleanup actions. [3] Opportunities for green and sustainable practices exist throughout the site remediation process of remedial investigation, design, construction, operation ...
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]
Land rehabilitation as a part of environmental remediation is the process of returning the land in a given area to some degree of its former state, after some process (industry, natural disasters, etc.) has resulted in its damage.
One definition for PRBs is an in situ treatment zone that passively captures a plume of contaminants and removes or breaks down the contaminants, releasing uncontaminated water. [1] The primary removal methods include: (1) sorption and precipitation , (2) chemical reaction, and (3) reactions involving biological mechanisms.
The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), also known as "Superfund", requires that the criteria provided by the Hazard Ranking System (HRS) be used to make a list of national priorities of the known releases or threatened releases of hazardous substances, pollutants, or contaminants in the United States.

In situ is a Latin phrase meaning “in the place”. When referred to chemistry or chemical reactions it means “in the reaction mixture”. In situ S/S, accounting for 20% of S/S projects from 1982–2005, is used to mix binding agents into the contaminated material while remaining on the site.
