Abstract
The document presents the field evaluation results of the ultraviolet radiation (UV)/oxidation technology developed by Ultrox International, Santa Ana, California. The field evaluation of the technology was performed at the Lorentz Barrel and Drum (LB&D) site in San Jose, California, under the Superfund Innovative Technology Evaluation (SITE) program from February 27 through March 10, 1989. The UV/oxidation technology uses UV radiation, ozone, and hydrogen peroxide to oxidize organic contaminants present in water. At the LB&D site, this technology was evaluated in treating ground water contaminated with volatile organic compounds (VOCs). The Ultrox system achieved VOC removals greater than 90%. The majority of VOC's were removed through chemical oxidation. However, for a few VOC's, such as 1,1,1-trichloroethane (1,1,1-TCA) and 1,1-dichloroethane (1,1-DCA) stripping also contributed toward removal. The treated ground water met the applicable discharge standards (NPDES) for disposal into a local waterway at 95% confidence level. There were no harmful air emissions from the Ultrox system into the atmosphere.
