With the continuing increase in population, more people are sharing the finite resources of the urban watershed, resulting in new and increasingly complex interactions between humans and the environment. Environmental contamination is a chronic problem-and an expensive one. In urban areas, water and soil contamination poses a threat to public health and has implications for future development. Taking an interdisciplinary approach, Urban Watersheds: Geology, Contamination, and Sustainable Development offers a framework for those working to improve the urban environment and create sustainable urban watersheds. The book presents over 20 years of research and professional practice on urban watersheds from the fields of environmental geology, geochemistry, risk analysis, hydrology, and urban planning. The geological characteristics of urbanized watersheds along with the properties of their common contaminants are integrated to assess risk factors for soil, groundwater, and air. With a framework rooted in scientific knowledge, the authors demonstrate the benefits of scientifically informed planning and decision making, offering guidelines to improve watershed management practices as well as urban development and redevelopment practices.Suitable for use as a textbook and as a professional practice reference, the book includes case studies on successful and unsuccessful approaches to contaminant remediation as well as practical methods for environmental risk assessment. PowerPoint presentations of selected portions of the book are available with qualifying course adoption.
