The use of innovative technologies in remediation activities is strongly promoted by Superfund. The Superfund site remediation process includes site characterization and remedy selection, often supplemented by treatability studies, remedial design and finally remedial action. The initial remedy selection may utilize information derived from treatability studies conducted simultaneously with the remedy selection process. However, remedial technologies, including innovative technologies, may be tentatively selected for application without the prior laboratory or field testing often necessary to confirm the selection. In these cases, the treatability studies are performed during the Remedial Design stage and function to determine the applicability of the innovative technology, as well as, develop site-specific design parameters. Ciba-Geigy technical staff systematically assesses contaminant types and site conditions for the potential application of innovative technologies. Bioremediation, soil flushing, soil vapor extraction (SVE) coupled with thermal treatment, low temperature thermal desorption (LTTD) and dechlorination (especially base catalyzed decomposition) are being evaluated. Three of these, soil flushing, SVE and LTTD, have progressed into the Remedial Design phase treatability studies, and show reasonable promise for success under the conditions present at several Ciba-Geigy sites.
