Recent and forecasted advances in microbiology, molecular biology, and analytical chemistry have made it timely to reassess the current paradigm of relying predominantly or exclusively on traditional bacterial indicators for all types of waterborne pathogens. Nonetheless, indicator approaches will still be required for the foreseeable future because it is not practical or feasible to monitor for the complete spectrum of microorganisms that may occur in water, and many known pathogens are difficult to detect directly and reliably in water samples. This comprehensive report recommends the development and use of a "tool box" approach by the U.S Environmental Protection Agency and others for assessing microbial water quality in which available indicator organisms (and/or pathogens in some cases) and detection method(s) are matched to the requirements of a particular application. The report further recommends the use of a phased, three-level monitoring framework to support the selection of indicators and indicator approaches.Â

Watershed management is an integrated approach that evaluates system-wide implications of natural resource problems. It has received considerable attention among communities and resource managers as an appropriate approach to deal with complex problems. Problem-solving is an important aspect of watersheds that involves diagnosis, assessment, solution, and implementation issues that often mean processing an enormous amount of information. A typical problem requires compilation of information from a variety of sources and is time consuming. This book will use a problem-based approach to present information on each problem facing watersheds. The subject area derives from a variety of disciplines and experiences and is presented clear and systematically throughout for easy reading and understanding. The problems covered in the book are major ones facing watersheds through the globe. The first chapter introduces principles of watershed management and is followed by chapters that are problem specific. Each problem is dealt with systematically with introduction, analysis, strategies, and further references. Watershed Management provides a valuable reference to professionals, students, scientists, and common citizens who are interested in learning about the variety of problems and approaches in watershed management.

Environmental Biotechnology: A Biosystems Approach, Second Edition presents valuable information on how biotechnology has acted as a vital buffer among people, pollution, and the environment. It answers the most important questions on the topic, including how, and why, a knowledge and understanding of the physical, chemical, and biological principles of the environment must be achieved in order to develop biotechnology applications. Most texts address either the applications or the implications of biotechnology. This book addresses both. The applications include biological treatment and other environmental engineering processes. The risks posed by biotechnologies are evaluated from both evidence-based and precautionary perspectives. Using a systems biology approach, the book provides a context for researchers and practitioners in environmental science that complements guidebooks on the necessary specifications and criteria for a wide range of environmental designs and applications. Users will find crucial information on the topics scientific researchers must evaluate in order to develop further technologies. Provides a systems approach to biotechnologies which includes the physical, biological, and chemical processes in context Presents relevant case studies on cutting-edge technologies, such as nanobiotechnologies and green engineering Addresses both the applications and implications of biotechnologies by following the lifecycle of a variety of established and developing biotechnologies Includes crucial information on the topics scientific researchers must evaluate in order to develop further technologies
