8 Preface This handbook is intended to be a working document which assists scientists, engineers, consultants, regulators, citizen groups, and environmental managers in determining if stormwater runoff is causing adverse effects and beneficial-use impairments in local receiving waters. This includes adverse effects on aquatic life and human health and considers exposures to multiple stressors such as pathogens, chemicals, and habitat alteration. Given the complicated nature of the problem, where diffuse inputs contain multiple stressors which vary in intensity with time (and often in areas which are simultaneously impacted by point source discharges or other development activities, e.g., channelization), it is difficult to define and separate stormwater effects from these other factors. To accomplish this task requires an integrated watershed-based assessment approach which focuses on sampling before, during, and after storm events. This handbook provides a logical approach for an experimental design that can be tailored to address a wide range of environmental concerns, such as ecological and human health risk assessments, determining water quality or biological criteria exceedances, use impairment, source identification, trend analysis, determination of best management practice (BMP) effectiveness, stormwater quality monitoring for NPDES Phase I and II permits and applications, and total maximum daily load (TMDL) assessments. Despite the complexity of stormwater, successful and accurate assessments of its impact are possible by following the logical integrated approaches described in this handbook. New methods and technologies are rapidly being developed, so this should be considered a living document which will be updated as the science warrants. We welcome your input on ways to improve future editions.

9 Acknowledgments We are indebted to our professional colleagues whose prior contributions enabled us to produce this book. In addition, the long productive hours of a host of graduate and undergraduate students at Wright State and the University of Alabama at Birmingham are acknowledged for their essential research contributions. We greatly appreciate the word processing of Nancy Pestian and Amy Ray. We also thank the production staff and editors at Lewis Publishers/CRC Press for their hard work and patience. The support of the U.S. EPA, especially Richard Field, is also appreciated, not only for help in the preparation of this current work, but also for the prior support given to many of the research projects described in this book. Special thanks are also due to our families, who provided never-ending support during the preparation of this book.

10 About the Authors G. Allen Burton, Jr., is the Brage Golding Distinguished Professor of Research and Director of the Institute for Environmental Quality at Wright State University. He obtained a Ph.D. degree in Environmental Science from the University of Texas at Dallas in From 1980 until 1985 he was a Life Scientist with the U.S. Environmental Protection Agency. He was a Postdoctoral Fellow at the National Oceanic and Atmospheric Administration s Cooperative Institute for Research in Environmental Sciences at the University of Colorado. Since then, he has had positions as a NATO Senior Research Fellow in Portugal and Visiting Senior Scientist in Italy and New Zealand. Dr. Burton s research during the past 20 years has focused on developing effective methods for identifying significant effects and stressors in aquatic systems where sediment and stormwater contamination is a concern. His ecosystem risk assessments have evaluated multiple levels of biological organization, ranging from microbial to amphibian effects. He has been active in the development and standardization of toxicity methods for the U.S. EPA, American Society for Testing and Materials (ASTM), Environment Canada, and the Organization of Economic Cooperation and Development (OECD). Dr. Burton has served on numerous national and international scientific committees and review panels, and written more than 100 publications dealing with aquatic systems. Robert Pitt is currently a Professor in the Department of Civil and Environmental Engineering at the University of Alabama. Bob had previously served on the School of Engineering faculty at the University of Alabama at Birmingham since Prior to that, he was a Senior Engineer for 16 years in industry and government, and continues to consult to many municipalities and engineering firms. He received his Ph.D. in Civil and Environmental Engineering from the University of Wisconsin Madison, his M.S.C.E. in Environmental Engineering/Hydraulic Engineering from San Jose State University, CA, and his B.S. in Engineering Science, from Humboldt State University, Arcata, CA. He is a registered professional engineer (WI) and a Diplomate of the American Academy of Environmental Engineers. During the past 30 years, Bob has been the project manager and principal investigator for many water resources research projects conducted for the U.S. EPA, Environment Canada, Ontario Ministry of the Environment, and state and local governments concerning the effects, sources, and control of urban runoff. Some are used as case studies in this book. His major area of interest is in stormwater management, especially the integration of drainage and water quality objectives. He currently teaches classes in water supply and drainage design, hydrology, hydraulics, experimental design, and field sampling, plus a series on stormwater management. Bob has published more than 100 chapters, books, journal articles, and major research reports. He is a member of the American Society of Civil Engineers, the Water Environment Federation, the North American Lake Management Society, the American Water Resources Association, and the Society for Environmental Toxicology and Chemistry.
