  2. In situ chemical oxidation - Wikipedia

    en.wikipedia.org/wiki/In_situ_chemical_oxidation

    The ISCO delivery technology and reagents also could be enhanced. Currently, an oxidant is injected into the contaminated site and is distributed by the injection pressure, turbulence and advection. This method is effective with appropriate point spacing and slightly overlapping radius of influence (ROI).

  3. In situ chemical reduction - Wikipedia

    en.wikipedia.org/wiki/In_situ_chemical_reduction

    ISCR is usually applied in the environment by injecting chemically reductive additives in liquid form into the contaminated area or placing a solid medium of chemical reductants in the path of a contaminant plume. [1] It can be used to remediate a variety of organic compounds, including some that are resistant to natural degradation.

  4. Groundwater remediation - Wikipedia

    en.wikipedia.org/wiki/Groundwater_remediation

    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 ...

  5. In situ bioremediation - Wikipedia

    en.wikipedia.org/wiki/In_situ_Bioremediation

    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.

  6. Bioremediation - Wikipedia

    These specific criteria may make it difficult to perform bioremediation on a contaminated site. In agricultural industries, the use of pesticides is a top factor in direct soil contamination and runoff water contamination. The limitation or remediation of pesticides is the low bioavailability. [57]

  7. Permeable reactive barrier - Wikipedia

    en.wikipedia.org/wiki/Permeable_reactive_barrier

    At the time, the best available remediation technology was pump and treat technology. PRBs presented a more cost-effective solution to the problem at hand, being able to passively remediate the groundwater. Granular metal was chosen as the reactive media after laboratory testing using contaminated water from the site.

  8. List of Superfund sites in Ohio - Wikipedia

    This is a list of Superfund sites in Ohio designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law.The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations. [1]

  9. Environmental remediation - Wikipedia

    en.wikipedia.org/wiki/Environmental_remediation

    Dredging contaminated sediment in New Bedford Harbor, Massachusetts. The harbor is contaminated with polychlorinated biphenyls (PCBs).. 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.
