interests include physicochemical and microbial processes and applied aquatic chemistry with application to waste reduction and treatment, and remediation of contaminated soil and sediment. He is noted for work on phase partitioning and the treatment and fate of hydrophobic organic compounds. Dr. Luthy’s research emphasizes interdisciplinary approaches to understand the behavior and availability of organic contaminants and the application of these approaches to bioavialability and environmental quality criteria. His current work includes the in situ control of PCBs (polychlorinated biphenyls) and DDT (dichlorodiphenyltrichloroethane) in contaminated sediments, and the environmental fate and behavior of perfluorinated organic compounds and nitromusks in the aquatic environment. Dr. Luthy chairs the National Research Council’s (NRC’s) Water Science and Technology Board and was a member of the NRC Committees on Innovative Remediation Technologies and on Intrinsic Remediation. He chaired the recently completed NRC study on the bioavailability of contaminants in soils and sediments. He is a past president of the Association of Environmental Engineering and Science Professors. He is a registered professional engineer, a diplomate of the American Academy of Environmental Engineers, and a member of the National Academy of Engineering.

Bruce A. Macler is national microbial risk assessment expert in the Water Division of the U.S. Environmental Protection Agency (Region 9). As national expert for microbial risk assessment for EPA, Dr. Macler provides guidance and assists in developing agency policies and programs in human health and ecosystem risk assessment and risk management. Prior to his current assignment, he served as national drinking water regulations manager from 1993 to 1997. Before joining the EPA in 1989, he was an assistant research botanist and lecturer at the University of California, Berkeley (1982-1987) and as assistant research professor in the Marine Sciences Research Center at the State University of New York at Stony Brook (1981-1982). Dr. Macler earned his A.B. (1974) and his Ph.D. (1981) in biochemistry from the University of California, Berkeley. His current research interests center on determining the magnitude and causes of waterborne microbial disease. This work has included several studies on the occurrence of fecal pathogens in groundwater, their fate and transport in the subsurface environment, and approaches to assessing public health impacts from these contaminants. Associated research interests include public perceptions on the safety of drinking water and their implications for regulatory water policy. Major current activities involve characterization of vulnerability to bioterrorism attacks on drinking water and development of a risk assessment paradigm for indoor molds. As national drinking water regulation coordinator for EPA Region 9, Dr. Macler participates actively in the development and implementation of all national primary drinking water regulations.
