Soil and/or water treatment by pollutants’ oxidation or reduction

Oxidation (In-Situ Chemical Oxidation)
Pollutants are directly marred with oxidants such as persulfates or peroxides.

Reduction (In-Situ Chemical Reduction)
Pollutants are directly marred with a reducing agent such as zero-valent iron

Oxidants and reducing agents can be put in contact with pollutants though several techniques such as:

  • soil mixing : treatment injected in wells
  • direct push : pressurized injection
