Progressive DOE Superfund site cleanup with advanced technologies

Lawrence Livermore National Laboratory proposes to apply advanced technologies for site remediation to achieve negotiated closure of the Livermore Superfund site. This new LLNL approach integrates scientific, technical, operational, and regulatory project components to save decades of work and hundreds of millions of dollars over realistic current life-cycle cleanup estimates. Overall savings for DOE will be amplified if this integrated approach is applied across the defense complex. The LLNL site cleanup will apply new in situ remediation technologies to destroy contaminant sources and intercept migrating plumes. These technologies will be focused where significant amounts of contaminant (greater than 50 parts per billion) reside in the subsurface. Focusing the most aggressive cleanup methods on these targets will cut the volume of soil to be treated from an original estimate of about 50M m{sup 3} to about 3M m{sup 3}--a factor of over 15 in volume reduction. While the new technologies are fielded and operated, advanced pump-and-treat methods employed at the site perimeter will control off-site movement of contaminants.
