The U.S. Environmental Protection Agency (EPA), the U.S. Air Force Armstrong Laboratory's Environics Directorate, and the U.S. Air Force Center for Environmental Excellence hosted a conference entitled "Symposium on Natural Attenuation of Chlorinated Organics in Ground Water" in Dallas, Texas, September 11-13, 1996. Approximately 650 people attended, including researchers; field personnel from federal, state, and local agencies; and representatives from industry and academia. Four speakers opened the symposium with welcoming remarks and introductory talks on the role of natural attenuation in remediating contaminated sites.
The 29 papers and 32 posters presented at the symposium highlighted recent achievements in the use of natural attenuation at particular sites, new research on the efficacy of natural attenuation, developments in site characterization and modeling techniques, and the place of natural attenuation in the current regulatory framework. These presentations represent the sate of the art in the use of natural attenuation as a tool in remediating hazardous waste sites.
