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]
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.
Some examples of bioremediation related technologies are phytoremediation, bioventing, bioattenuation, biosparging, composting (biopiles and windrows), and landfarming. Other remediation techniques include thermal desorption, vitrification, air stripping, bioleaching, rhizofiltration, and soil washing. Biological treatment, bioremediation, is a ...
Bioremediation is classified by the organism responsible for remediation with three major subdivisions: microbial remediation, phytoremediation, and mycoremediation. [18] In most cases, bioremediation works to either increase the numbers of naturally occurring microorganisms or add pollutant-specific microbes to the area.
The Sun Oil pipeline spill in Ambler, Pennsylvania spurred the first commercial usage of in situ bioremediation in 1972 to remove hydrocarbons from contaminated sites. [6] A patent was filed in 1974 by Richard Raymond, Reclamation of Hydrocarbon Contaminated Ground Waters, which provided the basis for the commercialization of in situ bioremediation.
Biosparging is an in situ remediation technology that uses indigenous microorganisms to biodegrade organic constituents in the saturated zone. In biosparging, air (or oxygen) and nutrients (if needed) are injected into the saturated zone to increase the biological activity of the
The process of identifying sustainable remediation is defined by The UK Sustainable remediation Forum [2] as “the practice of demonstrating, in terms of environmental, economic and social indicators, that the benefit of undertaking remediation is greater than its impact, and that the optimum remediation solution is selected through the use of a balanced decision-making process.”
Superfund is a United States federal environmental remediation program established by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). [1] The program is administered by the Environmental Protection Agency (EPA) and is designed to pay for investigating and cleaning up sites contaminated with hazardous ...
