  2. 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.

  3. 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 ...

    en.wikipedia.org/wiki/Nanoremediation

    It is being explored to treat ground water, wastewater, soil, sediment, or other contaminated environmental materials. [1] [2] Nanoremediation is an emerging industry; by 2009, nanoremediation technologies had been documented in at least 44 cleanup sites around the world, predominantly in the United States.

    en.wikipedia.org/wiki/In_situ_chemical_oxidation

    The in situ in ISCO is just Latin for "in place", signifying that ISCO is a chemical oxidation reaction that occurs at the site of the contamination. The remediation of certain organic substances such as chlorinated solvents (trichloroethene and tetrachloroethene), and gasoline-related compounds (benzene, toluene, ethylbenzene, MTBE, and ...

    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.

    S/S technologies were used to treat a contaminated former wood treating facility in Port Newark, New Jersey. Approximately 8 acres (32,000 m 2) of soil was contaminated by wood with arsenic, chromium, and polycyclic aromatic hydrocarbons. 8% of Portland cement was used by wet weight of contaminated soil. Both in situ and ex situ processes were ...

  9. In situ chemical reduction - Wikipedia

    en.wikipedia.org/wiki/In_situ_chemical_reduction

    The in situ in ISCR is just Latin for "in place", signifying that ISCR is a chemical reduction reaction that occurs at the site of the contamination. Like ISCO, it is able to decontaminate many compounds, and, in theory, ISCR could be more effective in ground water remediation than ISCO.
