ORNL scientists published in prestigious scientific journal
OAK RIDGE, Tenn.,
March 8, 1996
Robert L. Siegrist and Olivia R. West, researchers in the Environmental Sciences Division at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL), have had a three-part series of papers addressing the cleanup of volatile organic compounds published in the Environmental Science and Technology Journal.
The journal, sponsored by the American Chemical Society and considered one of the top scholarly publications in the environmental science field, focuses on environmental chemistry and remediation technology. The Siegrist and West papers describe how their team used complementary laboratory, field and modeling studies to develop and demonstrate in-situ mixed region vapor stripping for successfully removing trichloroethene (TCE) from clay soil at DOE's Portsmouth Gaseous Diffusion Plant in Ohio. In-situ methods decontaminate and remediate soil in place, without removing it for treatment and replacing it. Beginning in 1992, the interdisciplinary work spanned four years from performing and documenting their project to publication by the journal.
Key research collaborators from ORNL include Mike Morris of the Chemical Technology Division; Roger Jenkins of the Chemical and Analytical Sciences Division; and Dennis Greene and Doug Pickering of the Health Sciences and Research Division. Lending additional support were John Gierke of Michigan Technological University, Chemical Waste Management Corp., Millgard Environmental and Envirosurv. Doug Davenport, Tom Houk and Bob Barnett of Lockheed Martin Energy Systems in Portsmouth, Ohio, were instrumental in facilitating and supporting conduct of the work.
Siegrist, originally from Waukesha, Wis., completed bachelor's, master's and doctorate degrees in civil and environmental engineering at the University of Wisconsin at Madison. A registered professional engineer, he joined ORNL in 1990 as a research staff member and has won two achievement awards for distinguished performance. He has received more than 18 research grants and contracts related to environmental remediation technologies and has published extensively within the scientific community and in technical reports.
Siegrist was recently appointed to a two-year fellowship with the North Atlantic Treaty Organization (NATO) to continue his research on emerging technologies for remediation of contaminated land.
West earned bachelor of science and master of science degrees in civil engineering at the University of the Philippines, in her home country. She received her doctorate in civil engineering from the Massachusetts Institute of Technology in 1991 and joined ORNL on a Wigner Fellowship, the highest entry-level honor a scientist can obtain at ORNL. Her research interest is the remediation of volatile organic compounds in the environment.
ORNL, one of DOE's multiprogram national research and development facilities, is managed by Lockheed Martin Energy Research Corp.
