Although still considered an "innovative, alternative" remediation technique, In-situ Chemical Oxidation (ISCO) has become a mainstream approach to site clean-up.
The principle behind ISCO's effectiveness is the use of oxidizing chemicals, such as hydrogen peroxide, to neutralize contamination caused by petroleum and volatile organic compounds (VOCs) in soil and groundwater. Interest in this technology continues to grow as its effectiveness and cost benefits become more widely known. In many cases, treatments with ISCO can be so effective that site closure can be achieved without the need for long-term remediation such as pump and treat or soil vapor extraction (SVE). In other cases, ISCO has enabled site closure without property use restrictions. ISCO technology has particular value in difficult areas where traditional excavation and/or treatment methods are not cost-effective. This treatment is non-destructive for structures at the site, which reduces post-remediation repair costs. Historical experience has shown cost and time savings of one third of the cost and one fifth of the time of conventional remedial methods.
Norfolk Ram Principal, Brian V. Moran, P.E., LSP has been a pioneer in the development and application of this technology and was the first to use this innovative technology in New England on a full-scale basis.
