The U.S. Environmental Protection Agency (EPA) is engaged in an initiative called the Superfund Innovative Technology Evaluation (SITE) program. This program offers a mechanism for conducting joint technology demonstration/evaluation projects between the private sector and EPA. The purpose of the program is to provide an opportunity for developers to demonstrate the performance of their technologies on actual hazardous waste materials, and provide reliable and accurate information for future cleanup activities at Superfund sites. Currently there are 38 active projects in the Demonstration Program. Eight of these projects involve solidification/stabilization, nine concentrate on thermal processes, five are biological processes, and the remaining 16 include separation techniques, chemical treatment, and in-place vitrification. The paper briefly describes the active program and highlights those demonstrations which have been completed.
