  2. Groundwater remediation - Wikipedia

    en.wikipedia.org/wiki/Groundwater_remediation

    Groundwater remediation is the process that is used to treat polluted groundwater by removing the pollutants or converting them into harmless products. Groundwater is water present below the ground surface that saturates the pore space in the subsurface.

  3. Arsenic contamination of groundwater - Wikipedia

    en.wikipedia.org/wiki/Arsenic_contamination_of...

    Arsenic contamination of groundwater is a form of groundwater pollution which is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater. It is a high-profile problem due to the use of deep tube wells for water supply in the Ganges Delta , causing serious arsenic poisoning to large numbers of people.

    en.wikipedia.org/wiki/Permeable_reactive_barrier

    A permeable reactive barrier (PRB), also referred to as a permeable reactive treatment zone (PRTZ), is a developing technology that has been recognized as being a cost-effective technology for in situ (at the site) groundwater remediation. PRBs are barriers which allow some—but not all—materials to pass through.

    en.wikipedia.org/wiki/Environmental_remediation

    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.

    en.wikipedia.org/wiki/Air_sparging

    Air sparging, also known as in situ air stripping [1] and in situ volatilization is an in situ remediation technique, used for the treatment of saturated soils and groundwater contaminated by volatile organic compounds (VOCs) like petroleum hydrocarbons, [2] a widespread problem for the ground water and soil health.

  9. In situ chemical oxidation - Wikipedia

    en.wikipedia.org/wiki/In_situ_chemical_oxidation

    This poses a problem in ground water remediation, because the chemical must be able to mix with water to remove the contaminant. Fortunately, ozone (O 3) is about 12 times more soluble than O 2 [5] and, although it is still comparably insoluble, it is a strong oxidant. [3] The unique part of ozone oxidation is its in-situ application.
