PREFACE As part of the Comprehensive Environmental Response, Compensation, and Liability Act process for remediation of Waste Area Grouping (WAG) 6 at Oak Ridge National Laboratory, a public meeting was held on the proposed plan. It was recognized that contaminant releases from WAG 6 posed minimal potential risk to the public and environment. The U.S. Department of Energy (DOE) in conjunction with the U. S. Environmental Protection Agency and the Tennessee Department of Environment and Conservation agreed to defer remedial action at WAG 6 until higher risk release sites were first remediated. Energy under Contract DE-ACOS-84OR2 1400. The Pacific Northwest National Laboratory (PNNL) is operated by Battelle Memorial Institute for the U.S. Department of Energy under Contract DE ACO6-76RLO 1830. the support and guidance (both technical and administrative) provided by the ORNL Project Manager for this work, Dr. John R. Trabalka. The authors also wish to acknowledge the support provided by Messrs. C. K. Hyman, T. D. Powell, and W. A. Sliger of PNNL in the staging and performance of several of the ISV tests performed for this work. Their diligence made it possible to get these experhems off in a timely fashion. Moreover, their expertise with the engineeringscale ISV facility and its appurtenances helped ensure the successful performance of these tests.
