In-situ Chemical Oxidation (ISCO):
involves injecting oxidants and other supplements as may be required directly into the source zone and down plume gradient to remediate contaminated groundwater and soil. It is a double action method (remediation of soil and water concurrently) and requires drilling of injection wells to reach the contaminants. The oxidants react with the contaminants, producing innocuous substances such as carbon dioxide (CO2) and water (H2O).
In-situ Soil Vapor Extraction:
TIP engages Soil vapor extraction (SVE) as an in-situ remediation technology that involves the installation of a series of “wells” in the contaminated soil above the water table and placing a negative pressure on wells in the vadose zone to pull contaminated soil vapors from the subsurface soils.
