Radioactive wastes resulting from over 40 years of production of nuclear weapons in the U. S. are currently stored in 273 underground tanks at the U. S. Department of Energy Hanford site, Idaho National Engineering and Environmental Laboratory, Oak Ridge Reservation, and Savannah River site. Combined, tanks at these sjtes contain approximately 94,000,000 gallons of waste in a variety of forms including liquid, concrete-like salt cake, and various sludges. More than 730,000,000 curies of several radioactive isotopes are present in the underground tanks. Certainly, one of the greatest challenges facing the U. S. Department of Energy is how to characterize, retrieve, treat, and immobilize the great variety of tank wastes in a safe, timely, and cost-effective manner. For several years now, the U. S. Department of Energy has initiated and sponsored scientific and engineering studies, tests, and demonstrations to develop the myriad of technologies required to dispose of the radioactive tank wastes. In recent times, much of the Department of Energy R&D activities concerning tank wastes have been closely coordinated and organized through the Tanks Focus Area (IF A); responsibility for technical operations of the TF A has been assigned to the Pacific Northwest National Laboratory.

The second, enlarged edition of this established reference integrates many new insights into wastewater hydraulics. This work serves as a reference for researchers but also is a basis for practicing engineers. It can be used as a text book for graduate students, although it has the characteristics of a reference book. It addresses mainly the sewer hydraulician but also general hydraulic engineers who have to tackle many a problem in daily life, and who will not always find an appropriate solution. Each chapter is introduced with a summary to outline the contents. To illustrate application of the theory, examples are presented to explain the computational procedures. Further, to relate present knowledge to the history of hydraulics, some key dates on noteworthy hydraulicians are quoted. A historical note on the development of wastewater hydraulics is also added. References are given at the end of each chapter, and they are often helpful starting points for further reading. Each notation is defined when introduced, and listed alphabetically at the end of each chapter. This new edition includes in particular sideweirs with throttling pipes, drop shafts with an account on the two-phase flow features, as well as conduit choking due to direct or undular hydraulic jumps.

Artificial or constructed wetlands are an emerging technology particularly for tropical areas with water scarcity. For big cities, the sustainable management of water resources taking into account proper use is always challenging. The book presents case studies illustrating the above. As plants and microorganisms are a fundamental part of the correct functioning of these systems, their contribution to the degradation of the organic matter and to the removal and transformation of the pollutant compounds present in the wastewaters is also a highlight of this book.

Did you know that watching your favourite series on tv or just switching on your laptop for work, requires indirect water consumption? It's a proven fact that every time we use energy resources, water is also consumed. In the next few decades, global water and energy demands will increase significantly, but at this time there isn't a lot of information on expected global changes. The Water Research Institute (WRI) estimates that around 33 countries will experience very high water stress by 2040. Which means that as water scarcity rises due to rapid population growth, climate change and water deterioration, the global demand for pure water will also increase. We hope this book will help answer some of the challenges. The 13 chapters of this book were selected from multiple disciplines which focused on the state-of-the-art technologies in the field of environmental applications. These include technical-economic aspects of chemical precipitation; different substrates and concentrations of double chamber microbial fuel cells; the impact of pre-treatment on COD from paper industry wastewater; the synthesis of PES/Go-SiO2 mixed matrix membranes; predictions of a wastewater treatment plants performance of aeration demands; the performance of hydrological models for green roofs; short-term flexibility for energy grids from wastewater treatment plants; an integrated platform between water-energy-nexus and a business model for sustainable development; resilience-informed decision making in critical infrastructure networks. In Focus - a book series that showcases the latest accomplishments in water research. Each book focuses on a specialist area with papers from top experts in the field. It aims to be a vehicle for in-depth understanding and inspire further conversations in the sector.

In hard rock terrain, shallow water wells generally have a poor to moderate yield. Sinking wells deeply to tap yielding fracture zones often backfires, because the borehole may miss the saturated fracture zones at depths. A wrong approach to groundwater exploration in hard rock has therefore often led to unnecessary recurring expenditures and waste of time, something that could have been avoided by a systematic and proper geophysical approach. The combination of various geophysical techniques with environmental conditions is essential to constrain the interpretation and reduce uncertainties in this respect. This book presents the approach to groundwater exploration in hard rocks, various geophysical techniques and combinations to be used, interpretation of data with case studies and drilling results and the preparation of different utility maps.

Following the successful first edition of this book on drinking water quality and health, this new edition puts more focus on the importance of minerals in drinking water. It includes new scientific material and presents additional studies on the negative health effects of reverse osmosis water. The various safety organizations working on drinking water all warn about unhealthy constituents, as well as elements that can cause corrosion or scaling on pipes and installations. However, drinking water may also provide a substantial portion of the daily mineral intake, especially for the elderly and children, or those at risk of deficiencies due to unhealthy eating habits or starvation. Thus, a holistic approach to drinking water is presented in this book and the scope is extended from standards for undesirable substances to the basic mineral composition of water, examining 22 nutrient elements and ions and 21 toxic substances. The function of the nutrients in the body, symptoms of deficiency and overload, and advantages of the minerals from drinking water are presented, as well as symptoms of toxic elements from drinking water. The authors also suggest healthy ranges of minerals and mineral ratios for drinking water. The book offers a valuable resource for the health evaluation of drinking waters, for private well owners, public water producers and safety organizations alike.

The aim of preparation of current book is to provide the state-of-the-art knowledge about anaerobes and anaerobic process to undergraduate, graduate and PhD students. During the preparation of book we tried to incorporate contents from very basic like cultivation, handling, preservation and various important process related to anaerobes like biomethanation, anaerobic methanotrophy, solid waste management, anaerobic biohydrogen and biobutanol production, anaerobic nitrogen treatment, anaerobic solid waste management. In addition considering the importance of anaerobes in human health and disease we tried to dedicate a complete section like anaerobic probiotic, anaerobes and human gut microbiology and anaerobes and human infection. Finally we tried to incorporate a chapter on role of anaerobes in animal rumen and food digestion. We believe that current book will serve its aim to satisfy the hunger of knowledge about anaerobes and anaerobic process for the UG, PG and PhD students of Microbiology, Biotechnology, Environmental Science and Biochemistry background.

A River Flows Through It: A Comparative Study of Transboundary Water Disputes and Cooperation in Asia explores water disputes in Asia and addresses the question of how states sharing a river system can be incentivized to cooperate. Water scarcity is a major environmental, societal, and economic problem around the world. Increasing demand for water as a result of rapid economic development, high population growth and density has depleted the world's water resources, leading to floods, droughts, environmental disasters, and societal displacement. Shared river basins are therefore often a source of tension and conflict between states. In regions where relations between countries have historically been conflictual, scarce river water resources have exacerbated tensions and have even sparked wars. Yet, more often than not, states sharing a river basin are able to come to some form of agreement, whether they are far-reaching ones such as water-sharing agreements or those that are more limited such as the sharing of hydrological data. Why do riparian states cooperate, especially when power asymmetries between upstream and downstream countries are characteristic of transboundary river basins? How do non-state actors affect the management of international rivers? What are the conditions that facilitate or hinder cooperation? This book wrestles with these questions by exploring water disputes and cooperation in the major river systems in Asia, and by comparing them with cases in Africa, Europe, and the United States. This book will be of great value to scholars, students, and policymakers interested in transboundary water disputes and cooperation, hydro-diplomacy, and river activism. It was originally published as special issues of Water International.

The book covers in detail the topic of microplastics in water and wastewater. There is a growing interest in the scientific community in microplastics. Most of the studies identified the problems due to microplastics in the marine environment. However, considering that most microplastics are produced on land, similar problems should be encountered in freshwater systems and wastewater treatment plants that at the same time are the sources of marine microplastics. The human water cycle and points where the microplastics could interact with water will be presented as the introductory chapter. The subsequent chapters will examine evidence of the microplastics presence in freshwater such as both rivers and lakes and also, hazardous chemicals associated with microplastics in such systems. The following chapters will discuss the presence of microplastics in wastewater, their sources, their transfer through a wastewater treatment plant, their concentration in effluents throughout the world, and their distribution and effects on the surrounding environment of effluent wastewater pipes. Further chapters will discuss the sampling methods, the sample treatment and analysis techniques used so far for identifying microplastics in wastewater. Additionally, the presence of microplastics in sewage sludge and in soils irrigated with wastewater or fertilized with sludge, as well as the possible effects on plants and human health will be discussed. A concluding chapter will discuss the necessity for plastics strategies. In this second edition, a Study Guide is developed to be closely aligned with the content of the original text. Each study guide section includes the title of the relevant chapter, its aims, the expected learning outcomes, key concepts, a study plan, additional literature, and a set of self-assessment exercises and activities. Indicative answers to the self-assessment exercises and activities are provided at the end of the study guide. "All in all, the book is recommended for researchers and policymakers in the fields of environmental chemistry, civil engineering, city planning, waste management and toxicology. Furthermore, it is also worthwhile for those who are concerned about the effects of microplastics on biota and on humans." Professor Hideshige Takada, Laboratory of Organic Geochemistry (LOG), Tokyo University of Agriculture and Technology, International Pellet Watch

The need for improved sanitation around the world is becoming a crisis, and the situation is particularly critical in urban and peri-urban areas in developing countries. Here the population is growing rapidly, and where sanitation is provided, the means to treat and dispose of waste safely is neglected, with huge environmental and public health consequences. Sanitation solutions are needed that are safe for the user and interlinked with other urban services which can treat waste as a resource. This book describes an attempt to create modern, multi-storey urban dwellings that incorporate ecological sanitation into their design, resulting in a clean living space, and deriving safe agricultural inputs from human organic waste. The book highlights the experience of implementing the Erdos Eco-Town Project in Inner Mongolia, China. This remains the largest urban project of urine-diversion dry toilets in the world, serving a population of approximately 3000 people in 4 5 story apartment buildings. The multi-story collection system also links to on-site grey water treatment, a composting center, underground urine tanks, and the agricultural reuse of nutrients. "The Challenges of Urban Ecological Sanitation" describes the technical design, daily operation and maintenance, costs and benefits compared to conventional systems, as well as the challenges in achieving acceptability with users. It includes technical information and illustrations, but also stresses the institutional structure needed to support this system and discusses its long-term sustainability."The Challenges of Urban Ecological Sanitation" should be read by engineers, policy makers, researchers and NGO staff working in the field of water supply and sanitation."

The focus for the future must be on building urban resilience by strengthening the adaptive capacities of affected communities while also understanding the limits to adaptation. In Focus - a book series that showcases the latest accomplishments in water research. Each book focuses on a specialist area with papers from top experts in the field. It aims to be a vehicle for in-depth understanding and inspire further conversations in the sector.

Remediation of groundwater is complex and often challenging. But the cost of pump and treat technology, coupled with the dismal results achieved, has paved the way for newer, better technologies to be developed. Among these techniques is permeable reactive barrier (PRB) technology, which allows groundwater to pass through a buried porous barrier that either captures the contaminants or breaks them down. And although this approach is gaining popularity, there are few references available on the subject. Until now. Permeable Reactive Barrier: Sustainable Groundwater Remediation brings together the information required to plan, design/model, and apply a successful, cost-effective, and sustainable PRB technology. With contributions from pioneers in this area, the book covers state-of-the-art information on PRB technology. It details design criteria, predictive modeling, and application to contaminants beyond petroleum hydrocarbons, including inorganics and radionuclides. The text also examines implementation stages such as the initial feasibility assessment, laboratory treatability studies (including column studies), estimation of PRB design parameters, and development of a long-term monitoring network for the performance evaluation of the barrier. It also outlines the predictive tools required for life cycle analysis and cost/performance assessment. A review of current PRB technology and its applications, this book includes case studies that exemplify the concepts discussed. It helps you determine when to recommend PRB, what information is needed from the site investigation to design it, and what regulatory validation is required.
