SALLY L. BROWN is a research assistant professor in the College of Forest Resources, University of Washington. Prior to her appointment, she was a post-doctoral associate in the USDA Agricultural Research Service’s Environmental Chemistry Laboratory in Beltsville, Maryland. Her research interests include the co-utilization of residuals to alleviate metal toxicity in soils and the restoration of metal-affected ecosystems; in situ remediation of lead-contaminated soils using a range of soil amendments; and identification of the mechanisms by which residuals reduce the phytoavailability of soil metals. Dr. Brown has been the project leader for a number of research and demonstration programs at highly metal-contaminated sites in the United States. She received her B.A. in political science from Williams College and her M.S. and Ph.D. in agronomy from the University of Maryland, College Park.
DAVID A. DZOMBAK is a professor of environmental engineering at Carnegie Mellon University. He specializes in aquatic chemistry, especially interactions of aqueous chemical species with mineral surfaces; fate and transport of chemicals in surface and subsurface waters; water and wastewater treatment; in situ and ex situ soil treatment; and hazardous waste site remediation. Prior to 1989 Dr.Dzombak was a consulting engineer with Paul C. Rizzo Associates, Inc., where he conducted engineering investigation, analysis, and design related to remediation of uncontrolled waste disposal sites and development of new waste disposal facilities. He holds a Ph.D. in civil and environmental engineering from the Massachusetts Institute of Technology and M.S. and B.S. degrees in civil engineering from Carnegie Mellon University. Dr. Dzombak is a diplomat of the American Academy of Environmental Engineers, and from 1996–1999 served as board member and treasurer of the Association of Environmental Engineering and Science Professors.
SCOTT E. FENDORF is an assistant professor of soil and environmental chemistry in the Department of Geological and Environmental Sciences at Stanford University. His research focuses on understanding the movement of inorganic contaminants through soils and their impact on plants and animals. Dr. Fendorf studies the chemistry of the interactions of inorganic contaminants with water and mineral surfaces using spectroscopic techniques in idealized systems and with experiments in real soils systems. He received his B.S. in soil science from the California Polytechnic State University, San Luis Obispo, his M.S. in soil chemistry from the University of California, Davis, and his Ph.D. in soil and environmental chemistry from the University of Delaware.
JOHN P. GIESY is a professor of zoology in the College of Natural Sciences at Michigan State University. A former president of the Society of Environmental Toxicology and Chemistry, his primary research focus is on the fate and effects of trace contaminants, including metals, polyaromatic hydrocarbons, pesticides,
