Informationen zum Autor Julie Stauffer Zusammenfassung Modern society too often views water as a convenient vehicle for disposing of waste ? and the results are becoming increasingly apparent. Analysis of freshwater supplies frequently reveals disturbing levels of pollution, including human waste, heavy metals and synthetic chemicals, to the detriment of our health, and the health of entire ecosystems. The Water Crisis examines the roots of freshwater pollution ? urbanization, industrialization and intensive farming ? supported by case studies from the Rhine and the Great Lakes. It explores the impact of major pollutants and discusses methods of prevention. The final section provides a detailed overview of possible solutions, including soil-based treatment systems and constructed wetlands. A separate chapter is devoted to the important issue of groundwater pollution. Practical concise and accessible, this is ideal for students in environmental studies and environmental science, biology and geography, and general readers.
