Optimizing Stormwater Treatment Practices: A Handbook of Assessment and Maintenance provides the information necessary for developing and operating an effective maintenance program for stormwater treatment. The book offers instructions on how to measure the level of performance of stormwater treatment practices directly and bases proposed maintenance schedules on actual performance and historical maintenance efforts and costs. The inspection methods, which are proven in the field and have been implemented successfully, are necessary as regulatory agencies are demanding evaluations of the performance of stormwater treatment practices. The authors have developed a three-tiered approach that offers readers a standard protocol for how to determine the effectiveness of stormwater treatment practices currently in place.

Current research revolves around trends to bring technology into harmony with the natural environment and in order to protect the ecosystem. Bioremediation involves processes which reduce the overall treatment costs by using agricultural residues. Regeneration of the biosorbent further increases the cost effectiveness of the process, thus warranting its future success in solving water quality problems. Special emphasis is paid to chemical modifications resulting in tailored novel biomaterials which improve its sorption efficiency and environmental stability. In this way it can be used commercially as a simple, fast, economical, ecofriendly green technology, for the removal of toxic metals from waste water particularly in rural and remote areas of the country.

Switching off the pumps of a mine is one of the last steps in the lifetime of a surface or underground mine. As the water in the open space raises, the water might become contaminated with different pollutants and eventually starts to flow in the open voids. This book addresses the processes related to mine abandonment from a hydrogeological perspective. After an introduction to the relevant hydrogeochemical processes the book gives detailed information about mine closure procedures. Based on in-situ measurements the hydrodynamic processes in a flooded mine are described and some of the mine closure flow models exemplified. As all investigations base on precise data, the book gives some key issues of monitoring and sampling, especially flow monitoring. Then the book shows some new methodologies for conducting tracer tests in flooded mines and gives some hints to passive mine water treatment. At the end 13 well investigated case studies of flooded underground mine and mine water tracer tests are described and interpreted from a hydrodynamic point of view.

Environmental sustainability issues in a fragile, semi-arid region and its coastal area, which experience climate changes from extreme drought conditions to the effects of hurricanes over a period of weeks to years, provide specific challenges for the ecosystems and the populations existing within the region. The research presented focuses on the problems and some solutions specific to the South Texas-Mexico border region, on both sides of the Rio Grande, focusing on water and air pollution. "

Groundwater is the most important source of domestic, industrial, and agricultural water and also a finite resource. Population growth has created an unprecedented demand for water, with the situation most critical in the developing world, where several million people depend on contaminated groundwater for drinking purposes. Geogenic contaminants, such as arsenic and fluoride at toxic levels, pose major environmental risks and endanger public health. This book is a collection of papers providing a multi-disciplinary overview for scientists and professionals involved in the sustainable development of groundwater resources.

Few policy areas in recent history have the attention of the Australian public and polity as much as those relating to water. Water Policy in Australia considers the current policy reform agenda from agricultural, environmental, and cultural perspectives. It presents a comprehensive account of the country's critical water issues and provides expert perspectives from behavioral and institutional economists, engineers, hydrologists, sociologists, and water law specialists. norms, and values relating to the exploitation of water resources. Until the 1980s, the engineer was king, and policymakers viewed water as an endless resource for driving economic growth. However, in the last twenty years, policymakers have been forced to acknowledge that it is not possible to perpetually supply more water at a low cost. Consequently, the country has begun to focus on water resource management through legislative and institutional change - attempting to allocate water in a more economically efficient and socially and environmentally acceptable manner. institutional change, as well as valuable lessons on the design of property rights for complex resources. The editor and contributors look beyond recent reform efforts and address the hydrological, biophysical, economic, and social factors at play in Australia. The book addresses pertinent issues, such as irrigation in the Murray-Darling basin, one of Australia's largest drainage divisions; the progression from common law riparian rights to share-based entitlements that encourage sustainable water use; and the potential outcomes of the recent National Water Initiative, a wide-ranging strategy to improve water management and simultaneously maintain healthy groundwater and river systems.

Riverbank filtration is a low cost, yet efficient water treatment technology. It has most potential to provide safe drinking water to large cities located along rivers or lakes. In particular, it is ideal for large population centres in developing countries, where the cost of building extensive treatment facilities is prohibitive. Water filtration can be successfully implemented using naturally occurring sand and gravel along the river/lake banks. The cost of water produced by this means is much lower than that of water treated in conventional treatment plants. Authored by a multi-disciplinary team of experts, this volume addresses the scientific basis of the filtration process, and also numerous topics of importance for the planning, technical realization, and security of such plants. Their application for the removal of relevant chemical pollutants and a variety of pathogens is analysed in detail.

This book highlights the relationship between the water sector and various other sectors in order to establish an improved understanding of the importance of water resources as an essential cross-cutting vector of socio-economic development. The book is both policy and practice oriented and is not constrained by existing definitions on water security. It includes actual experiences of policy, management, development and governance decisions taken within the water sector, and examples on how these have affected the energy and agricultural sectors as well as impacted the environment, and vice versa, as appropriate. It also discusses trade-offs, short and long-term implications, lessons learnt, and the way forward. The book includes case studies on cities, countries and regions such as Australia, China, Singapore, Central Asia, Morocco, Southern Africa, France, Latin America, Brazil and California.

Nowhere is the conflict between economic progress and environmental quality more apparent than in the mineral extraction industries. The latter half of the 20th century saw major advances in the reclamation technologies. However, mine water pollution problems have not been addressed. In many cases, polluted mine water long outlives the life of the mining operation. As the true cost of long-term water treatment responsibilities has become apparent, interest has grown in the technologies that would decrease the production of contaminated water and make its treatment less costly. This is the first book to address the mine water issue head-on. The authors explain the complexities of mine water pollution by reviewing the hydrogeological context of its formation, and provide an up-to-date presentation of prevention and treatment technologies. The book will be a valuable reference for all professionals who encounter polluted mine water on a regular or occasional basis.

During the past three decades, urban groundwater has emerged as one of the world's most pressing issues. Explosive population growth, most prevalent in cities, has placed an inordinate demand on groundwater supply, prompting concerns for its long-term sustainability at a time when the quality of available groundwater resources is being increasingly degraded by anthropogenic activity. Cities less reliant on groundwater for potable supply are equally obliged to manage subsurface water with cautious respect since rising groundwater levels can generate a myriad of problems such as unstable land slopes, flooded basements, tunnels and electrical utilities, and the release of polluted water to urban wetlands, springs and streams.Challenges in Urban Groundwater is premised on a growing recognition that most urban groundwater problems are not uniquely associated with any particular region or hydrogeological environment, and much can be learned by understanding the successes and failures of others. It showcases the best urban groundwater papers presented at the International Geological Congress held in Florence, Italy in 2004, and is supplemented by contributions solicited from other world experts active in urban groundwater research. Topics covered range from the urban water balance and rising groundwater levels to groundwater contamination and the role of aquifer modelling.

The management of, and access to, water resources have been universally identified as a key aspect of poverty reduction, agriculture and food security and sustainable development in developing, transitional, and developed countries worldwide. Yet good "water governance," so eagerly sought, has in practice proven difficult to achieve. This book, edited and authored by leading authorities on water resource management, examines the recent changes in governance, institutions, economics, and policies of water, from a global point of view and a cross-country perspective, with special emphasis on African and Southern African case studies.The authors show that in recent years, water policies, institutions, and governance have shifted from technical, quantitative, supply-driven, centrally controlled management to more demand-sensitive, qualitative, decentralized, participatory, integrated approaches. Such a move also often supposes cost recovery principles, resource allocation among competing sectors, and privatization. In most developing countries, motivations for these changes have been increased resource scarcity, increased diversity of users and uses, urbanization, financial constraints and the need for sustainable development through renewed water management. Yet the creation and operation of new policies and legal frameworks often fall short of initial expectations since management transfer and decentralization processes, cost recovery principles and the emergence of new local organizations have proven difficult to implement. The book examines these issues through case studies at national, river basin, and local levels using accessible multidisciplinary approaches that integrate economics, institutional analysis, geography, and policy analysis. Ultimately the book untangles and presents best practices for policy and decision makers, governments and regulators, NGOs and user groups, farmers, water-supply companies, and researchers, and points towards how good water governance structures can be developed and implemented for the benefit of all.

Linsky National Water Research Institute Fountain Valley, California, United States Gina Melin National Water Research Institute Fountain Valley, California, United States 1. What is Riverbank Filtration? The purpose ofthis book is to show that riverbank filtration (RBF) isa low-cost and efficient alternative water treatment for drinking-water applications. There are two immediate benefits to the increased use of RBF: Minimized need for adding chemicals like disinfectants and coagulants to surface water to control pathogens. Decreased costs to the community without increased risk to human health. Butwhat,exactly, isRBF? In humid regions, river water naturally percolates through the ground into aquifers (which are layers of sand and gravel that contain water underground) during high-flow conditions. In arid regions, most rivers lose flow, and the percolating water passes through soil and aquifer material until it reaches the water table. During these percolation processes, potential contaminants present in river water are filtered and attenuated. If there are no other contaminants present in the aquifer or ifthe respective contaminants are present at lower concentrations, the quality of water in the aquifer can be ofhigher quality than that found in theriver. In RBF, production wells - which are placed near the banks ofrivers -pump large quantities ofwater.

The unit process approach, common in the field of chemical engineering, was introduced about 1962 to the field of environmental engineering. An understanding of unit processes is the foundation for continued learning and for designing treatment systems. The time is ripe for a new textbook that delineates the role of unit process principles in environmental engineering. Suitable for a two-semester course, Water Treatment Unit Processes: Physical and Chemical provides the grounding in the underlying principles of each unit process that students need in order to link theory to practice. Bridging the gap between scientific principles and engineering practice, the book covers approaches that are common to all unit processes as well as principles that characterize each unit process. Integrating theory into algorithms for practice, Professor Hendricks emphasizes the fundamentals, using simple explanations and avoiding models that are too complex mathematically, allowing students to assimilate principles without getting sidelined by excess calculations. Applications of unit processes principles are illustrated by example problems in each chapter. Student problems are provided at the end of each chapter; the solutions manual can be downloaded from the CRC Press Web site. Excel spreadsheets are integrated into the text as tables designated by a "CD" prefix. Certain spreadsheets illustrate the idea of "scenarios" that emphasize the idea that design solutions depend upon assumptions and the interactions between design variables. The spreadsheets can be downloaded from the CRC web site. The book has been designed so that each unit process topic is self-contained, with sidebars and examples throughout the text. Each chapter has subheadings, so that students can scan the pages and identify important topics with little effort. Problems, references, and a glossary are found at the end of each chapter. Most chapters contain downloadable Excel spreadsheets integrated into the text and appendices with additional information. Appendices at the end of the book provide useful reference material on various topics that support the text. This design allows students at different levels to easily navigate through the book and professors to assign pertinent sections in the order they prefer. The book gives your students an understanding of the broader aspects of one of the core areas of the environmental engineering curriculum and knowledge important for the design of treatment systems.
