【 摘 要 】

The Subsurface Contaminants Focus Area, (SCFA) is committed to, and has been accountable for, identifying and providing solutions for the most pressing subsurface contamination problems in the DOE Complex. The SCFA program is a DOE end user focused and problem driven organization that provides the best technical solutions for the highest priority problems. This paper will discuss in some detail specific examples of the most successful, innovative technical solutions and the DOE sites where they were deployed or demonstrated. These solutions exhibited outstanding performance in FY 2000/2001 and appear poised to achieve significant success in saving end users money and time. They also provide a reduction in risk to the environment, workers, and the public while expediting environmental clean up of the sites. Examples of the technical solutions include Dynamic Underground Stripping with Hydrous Pyrolysis Oxidation, In Situ Redox Manipulation, Lasagna, Passive Reactive Barriers, Enhanced In Situ Bioremediation, and Phytoremediation. The implementation of these technologies in the DOE Site cleanup effort has advanced the baselines for subsurface remediation at many sites and will result in major cost savings, while continuing to lower the risks and expedite the cleanup of problems for DOE, other agencies, and the private sector.
