Technology Board and Board on Environmental Studies and Toxicology. Dr. O'Melia earned a PhD in sanitary engineering from the University of Michigan. In 1989, Dr. O'Melia was elected to the National Academy of Engineering for significant contributions to the theories of coagulation, flocculation, and filtration leading to improved water-treatment practices throughout the world.


G. Allen Burton is a professor of environmental sciences and director of the Institute for Environmental Quality at Wright State University. He has served as a NATO senior research fellow in Portugal and a visiting senior scientist in Italy and New Zealand. He was the Brage Golding Distinguished Professor of Research at Wright State University. Dr. Burton's research during the last 25 years has focused on developing effective methods for identifying ecologic effects and stressors in aquatic systems where sediment and storm-water contamination is a concern. His ecosystem risk assessments have evaluated multiple levels of biologic organization, from microbial to amphibian effects. Dr. Burton serves on numerous national and international scientific committees, review panels, councils, and editorial boards, and he consults for industry and regulatory agencies. He earned his PhD in environmental science (aquatic toxicology) from the University of Texas at Dallas.


William Clements is a professor at Colorado State University, where he has served on the faculty since 1989. Dr. Clements’s primary research interests are in basic aquatic ecology and ecotoxicology. His research has focused on understanding how benthic macroinvertebrate communities respond to natural and anthropogenic stressors. More recently, his research projects have included assessments of recovery from fire disturbance, quantifying interactions between natural and anthropogenic stressors, and measuring abiotic factors that influence contaminant bioavailability. Dr. Clements has a substantial record of publication on benthic invertebrates, benthic community interactions, and effects of stressors. He is the author of several book chapters and a coauthor of the book Community Ecotoxicology, published in 2002. Dr. Clements earned his PhD in zoology from Virginia Polytechnic Institute and State University in 1988.
