This issue paper has been prepared by EPA's Federal Facilities Forum to provide information about technologies available for treatment of perchlorate contamination in environmental media, including technologies that have been used to date and others that show potential for treating such contamination. Furthermore, this paper provides site-specific information on 51 projects where treatment technologies have been or are being applied for full-scale treatment or field demonstrations. A brief overview of key perchlorate issues, including health effects and risks, regulatory standards and cleanup levels, degradation processes, and treatment technologies, is provided to give the reader context. However, these issues are not addressed in depth in this paper.
