In situ chemical oxidation is a remediation technology that uses specific chemical compounds in order to destroy or oxidize a variety of contaminants. In situ chemical oxidation (ISCO) can remediate soil contamination in very short timeframes (days to weeks). However, the chemical oxidant needs to have direct contact with the contaminant in order for the ISCO technology to effectively remediate the soils. This requires that the soil contamination be relatively shallow (in the upper 20 feet), have the ability to be vigorously mixed with the chemical oxidant (the site needs to be accessible with an excavator), and have the ability to develop into a slurry with the chemical oxidant. Typically, this technology is very effective at sites with subsurface soils composed of sands or silts.
