Pollutant Discharge And Water Quality In Urbanisation

The main purpose of water quality monitoring may be seen as evaluating water quality conformity against water quality standards, especially for administrative purposes. Moreover, water quality monitoring data can be applied to estimate and evaluate pollutant loads in rivers. Chronological water quality fluctuations and vertical water quality profiles in water bodies are also important when taking into account the effects of land-based pollutants on coastal sea and estuary water quality. This book discusses the relationships between pollutant discharge and water quality, taking into account urban development and indicators like the pollutant load per capita flowing into the water body (PLCwb), an index used to evaluate the contribution of municipal wastewater pollutant discharge to pollutant loads flowing into ambient water bodies such as coastal zones, bays and lakes.

Multidisciplinary treatment of the urgent issues surrounding urban pollution worldwide Written by some of the top experts on the subject in the world, this book presents the diverse, complex and current themes of the urban pollution debate across the built environment, urban development and management continuum. It uniquely combines the science of urban pollution with associated policy that seeks to control it, and includes a comprehensive collection of international case studies showing the status of the problem worldwide. Urban Pollution: Science and Management is a multifaceted collection of chapters that address the contemporary concomitant issues of increasing urban living and associated issues with contamination by offering solutions specifically for the built environment. It covers: the impacts of urban pollution; historical urban pollution; evolution of air quality policy and management in urban areas; ground gases in urban environments; bioaccessibility of trace elements in urban environments; urban wastewater collection, treatment, and disposal; living green roofs; light pollution; river ecology; greywater recycling and reuse; containment of pollution from urban waste disposal sites; bioremediation in urban pollution mitigation; air quality monitoring; urban pollution in China and India; urban planning in sub–Saharan Africa and more. Deals with both the science and the relevant policy and management issues Examines the main sources of urban pollution Covers both first-world and developing world urban pollution issues Integrates the latest scientific research with practical case studies Deals with both legacy and emerging pollutants and their effects The integration of physical and environmental sciences, combined with social, economic and political sciences and the use of case studies makes Urban Pollution: Science and Management an incredibly useful resource for policy experts, scientists, engineers and those interested in the subject.

The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Global water crisis is a challenge to the security, political stability and environmental sustainability of developing nations and with climate, economically and politically, induces migrations also for the developed ones. Currently, the urban population is 54% with prospects that by the end of 2050 and 2100 66% and 80%, respectively, of the world's population will live in urban environment. Untreated water abstracted from polluted resources and destructed ecosystems as well as discharge of untreated waste water is the cause of health problems and death for millions around the globe. Competition for water is wide among agriculture, industry, power companies and recreational tourism as well as nature habitats. Climate changes are a major threat to the water resources. This book intends to provide the reader with a comprehensive overview of the current state of the art in integrated assessment of water resource management in the urbanizing world, which is a foundation to develop society with secure water availability, food market stability and ecosystem preservation.

This multi-disciplinary book provides practical solutions for safeguarding the sustainability of the urban water environment. Firstly, the importance of the urban water environment is highlighted and the major problems urban water bodies face an

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. Originally published in 1998
