IN-SITU CHEMICAL OXIDATION
In situ chemical oxidation (ISCO), a form of advanced oxidation processes and advanced oxidation technology, is an environmental remediation technique used for soil and/or groundwater remediation to reduce the concentrations of targeted environmental contaminants to acceptable levels. ISCO is accomplished by injecting or otherwise introducing strong chemical oxidizers directly into the contaminated medium (soil or groundwater) to destroy chemical contaminants in place. It can be used to remediate a variety of organic compounds, including some that are resistant to natural degradation. of organic compounds, including some that are resistant to natural degradation..
Numac has a number of injection systems built to suit a wide variety of applications, and can modify each systems for project specific requirements.
In many situations an injection probe can be pushed to the required injection depth and pumping can commence without the installation of a permanent well. In this instance many locations can be targeted without the overheads that accompany permanent well installation and decommissioning.
Permanent injections wells allow for followup up injection events eliminating or reducing the requirement to have a rig on site for the program. Permanent wells with set screens do not however allow for tailoring injection depths after results from injection events is examined.
The use of MIP, UVOST & HPT will ensure that you have high resolutions data to plan an ISCO remediation event. The high resolution technologies will ensure you can identify preferential pathways, plume distribution and concentration to get the best results from an injection event.
