In situ chemical oxidation (ISCO) has been used to treat organic contaminants of concern (COCs) at thousands of sites around the world. This technology originated in the 1980’s with the application of unstabilized hydrogen peroxide. Over time ISCO has evolved to include several different chemistries including those based on hydrogen peroxide, sodium and potassium permanganate and sodium and potassium persulfate. As ISCO has become a standard tool used to remediate contaminated sites much effort has been put into learning and optimizing the technologies with the chemistries, design strategies, application methods, and monitoring programs, which have all evolved over the past decades.
Current best practices consider key site and contaminant characteristics, remedial objectives and how each of those interact with the selection of the proper ISCO chemistry and application method. Best practices have matured beyond treatment efficacy to also evaluate proper dose, rate of release of the oxidant, contaminant phase transfer limitations, best methods for establishing contact, contact time once contact is established, reaction kinetics, application method and monitoring programs.
The Short Course will address the following primary categories using case studies to illustrate key points:
- Site Characterization for Remediation
- Contaminant Chemistry and Partitioning
- ISCO Chemistry
- ISCO Design and Dosing
- Application Methods
- Monitoring Programs
Those attending this session should obtain an understanding of how critical design elements, oxidant characteristics, application method, and monitoring program are all interrelated and must be considered in conjunction with each other and the site/contaminant specifics in order to design the most appropriate remedy for the site.
The session will allow for open discussion with the presenters including the decisions made on actual sites. Please register here.
