Remediation Approaches – In Situ Chemical Oxidation (ISCO), Part 1
Is ISCO a good choice for your site? Many contaminants and site conditions are difficult to treat with conventional remediation technologies such as soil vapor extraction, air sparging, bioremediation, or pump and treat. In addition, conventional technologies are often costly and time-consuming. For the past 15 years oxidation has become a common alternative for in...

Remediation Approaches – In Situ Chemical Oxidation (ISCO), Part 2
When is ISCO a good fit for an environmentally impacted site? In situ chemical oxidation is not applicable to all contaminants or to all situations. Considerable research has been conducted and is continuing to determine the optimal contaminant–oxidant match. The application of in situ chemical oxidation is a step-wise procedure involving: Screening Bench ScaleTesting Pilot...
