NEWSLETTER NRMRL-CIN-1727 Gallardo*, V. Photocatalytic Treatment of Air Emissions Resulting from Ground-water Treatment, "Ground Water Currents" EPA/542-N-01-008, Issue 42. 2001. 12/21/2001 A new system for treating off-gas from ground water remediation systems containing chlorinated organic compounds has been demosntrated under USEPA's Superfund Innovative Technical Evaluation (SITE) Program. Results indicate that this technology, known as the adsorption-integrated-reaction (AIR2000) process, removed trichloroethylene (TCE) by more than 99.5% and trace levels of other targeted compounds by more than 98.5%. Starting concentrations for TCE averaged 56 ppmv. In addition, the process successfully met state standards for volatile organic compounds emissions.
