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.
Environmental - If the environment a business works in becomes polluted as the result of the activities of that business, or sometimes other events, this pollution must be cleaned for reasons of safety and welfare. This will normally involve the business either financing the remedial action or applying for the finances to do so.
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.
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 ...
Other remediation techniques include thermal desorption, vitrification, air stripping, bioleaching, rhizofiltration, and soil washing. Biological treatment, bioremediation, is a similar approach used to treat wastes including wastewater, industrial waste and solid waste.
Bioventing is an on site remediation technology that uses microorganisms to biodegrade organic constituents in the groundwater system. Bioventing enhances the activity of indigenous bacteria and archaea and stimulates the natural in situ biodegradation of hydrocarbons by inducing air or oxygen flow into the unsaturated zone and, if necessary ...
Ex situ remediation refers to reactions performed outside the natural habitat of these organisms. Increased microbial activities through aeration, irrigation, and creation of bio-piles. Increased degradation activities via turning of polluted soils and addition of minerals and water.
Landfarming is an ex situ waste treatment process that is performed in the upper soil zone or in biotreatment cells. Contaminated soils, sediments, or sludges are transported to the landfarming site, mixed into the soil surface and periodically turned over to aerate the mixture. [1]
