This book provides the reader with the comprehensive view necessary to understand and critically evaluate the design, implementation, and monitoring of phytoremediation at sites characterized by contaminated groundwater.   Part I presents the historical foundation of the interaction between plants and groundwater, introduces fundamental groundwater concepts for plant physiologists, and introduces basic plant physiology for hydrogeologists.   Part II presents information on how to assess, design, implement, and monitor phytoremediation projects for hydrologic control.   Part III presents how plants take up and detoxify a wide range of organic xenobiotics in contaminated groundwater systems, and provides various approaches on how this can be assessed and monitored.   Throughout, concepts are emphasized with numerous case studies, illustrations and pertinent literature citations.   This book will be of interest to those professionals dealing with environmental contamination, hydrology, plant physiology, toxicology, microbiology, and resource economics.
