The increasing global recognition of the potential risks associated with surface water or ground water contamination and speciÞc environmental regulations implemented after 1980 have demanded a more accurate understanding of these risks as they relate to human health and the envi- ronment. Modeling has become an invaluable tool in providing the necessary infor- mation to understand the risks associated with contaminants in complex environ- ments with complicated environmental processes. Although improvements in computing power provided by modern personal com- puters and various new computational methods have allowed the development of more sophisticated environmental models, many technical issues and disagreements on particular modeling approaches and methods remain. Because the public, gov- ernment agencies, and industry all have a high level of interest and stake in envi- ronmental protection and remediation, and because billions of dollars are spent every year for remediation, the need for a comprehensive review of the theory, practice, and future direction of modeling technology is becoming more urgent. The forma- tion, requested by the U.S. Environmental Protection Agency (USEPA), of the Environmental Modeling Subcommittee of the Science Advisory Board in 2000, the effort ordered by the USEPA Administrator in 2003 to revitalize the agency’s Council for Regulatory Environmental Modeling (CREM), and a panel study on the same issue recently planned by the National Research Council (NRC) best explain the increasing urgency to better understand modeling technology development and appli- cation so that a more reasonable and defensible decision-making process for envi- ronmental issues can be achieved. The DuPont Company provided a forum and necessary support for this purpose. A workshop, Modeling and Management of Emerging Environmental Issues — Expert Workshop 2000 , was planned, organized, and chaired by Calvin C. Chien, leader of environmental modeling technology and development for the DuPont Corporate Remediation Group (CRG). Approximately four dozen modeling experts from the U.S. and Canada were carefully selected and invited to participate in this effort. Four panels were formed, with each addressing one of the following primary environmental contamination and remediation issues involving modeling: (1) Mixing Zone: Discharge of Contaminated Ground water into Surface Water Bodies, (2) Contaminated Sediment: Its Fate and Transport, (3) Optimization Modeling for Remediation and Monitoring, and (4) Simulation of Halogenated Hydrocarbons in the Subsurface. Although the details of these issues vary, all involve technical and/or regulatory challenges and a high Þnancial stake. Each panel had a panel leader who worked with the CRG to select the panel members, outline the panel discussion, facilitate the discussion at the workshop, and L1667_C00.fm Page v Tuesday, October 21, 2003 3:50 PM ©2004 CRC Press LLC help prepare the manuscripts for the chapters presented in this book. The workshop was held from July 25 to 27, 2000, at the campus of Penn State University Great Valley in Malvern, PA. An assistant panel leader supported each leader and took discussion notes, which helped panelists in the preparation of this book. A complete list of panelists and their afÞliations are provided in Appendix A. This book was prepared using the information generated from workshop discus- sions and additional materials provided by the panelists. The primary objectives of this book were to provide information on the state of the art and current practice and identify the research and development needs of the modeling technologies discussed. It should be noted that the discussions herein are based not only on technical analysis but also on regulatory acceptance and cost effectiveness. This book comprises four chapters. Each chapter addresses one of the four topic areas discussed at the workshop. In most cases, a section of each chapter was prepared by a panel member and, in some cases, includes materials offered by other members. The panel leaders either assembled the material submitted by the panelists or further edited the manuscripts prior to overall editing. During the editing process, original submitted materials were modiÞed, expanded, and reorganized. As a result, it is impossible to accurately allocate credits to individual contributors. However, those individuals who made signiÞcant contributions are mentioned. The person responsible for assembling and editing each chapter manuscript is listed at the beginning of the chapter, followed by the names of signiÞcant contributors. Calvin C. Chien was responsible for the overall planning, preparation, and publication of the book. DuPont and the book contributors want to express their deep appreciations to Penn State Great Valley and Elayna McReynolds, the conference coordinator, for the support provided during the workshop. Special credit must be offered to Kathleen O. Adams, DuPont contract technical writer, for her deep involvement, dedication, and signiÞcant contributions throughout the editing process.
