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.

As government and community leaders, private companies, citizens, and applied scientists search for low-cost methods to cleanup environmental pollution, phytotechnologies can contribute to the solution by utilizing natural processes to reduce environmental risk. Phytotechnologies use vegetation to manage environmental contaminants in soil, surface water, and groundwater based on site-specific design considerations that can save 50 to 75 percent of the capital and operating costs compared to conventional remediation and containment technologies. Successful phytotechnology applications are based on scientific knowledge of plant physiology, chemical contaminants, climate, and soil conditions. This book presents current research findings that address soil and water contamination with obsolete pesticides, radionuclides and other inorganic and organic contaminants. This book documents international sharing of information by scientists and stakeholders seeking to use the best available information: to disseminate existing knowledge on phytotechnologies and exchange experience of field-scale applications for cleanup of industrial, agricultural, and wastewater contamination, to assess existing knowledge and identify research needs and directions for future work especially in regard to environmental management in Central and Eastern Europe and Central Asia, and to promote collaboration between different countries in preparing applications for environmental remediation and restoration.

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.

Reflecting the concerns over environmental sustainability, there has been an increasing focus on the protection of our water resources and on the proper management of our waste. Our economic growth can only be sustainable when it does not represent a threat to human health and to fauna, flora, and eco-system in the long-term. A long-term resilience, new business and economic opportunities, and environmental sustainability can be achieved through circular economy model that offers us a world of opportunity to rethink and redesign our economic activities and consumption patterns. With an aim to give the reader a new perspective on this issue, this book covers European Union's water and waste management legislation and the Czech Republic's transposition of this legislation, and includes a comparative analysis of the performances of the EU Member States on the implementation of new water and waste management policy strategies.

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.

This book will address the major subsoil physical and chemical constraints and their implications to crop production; Plant growth is often restricted by adverse physical and chemical properties of subsoils yet these limitations are not revealed by testing surface soils and hence their significance in crop management is often overlooked. The major constraints can be physical or chemical. Physical limitations such as poor/nil subsoil structure, sandy subsoils that do not provide adequate water or gravelly subsoils and, etc. On the other hand, chemical constraints include acidity/alkalinity, high extractable Al or Mn, low nutrient availability, salts, boron toxicity and pyritic subsoils. Some of these constraints are inherent properties of the soil profile while others are induced by crop and soil management practices. This aim of this book is to define the constraints and discuss amelioration practices and benefits for crop production. This book will be of interest to readers involved with agriculture and soil sciences in laboratory, applied or classroom settings.

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."

This book examines India's transboundary river water disputes with its South Asian riparian neighbours - Pakistan, Bangladesh, Nepal and Bhutan. It explores the history of disputes and cooperation over the transboundary river water in this region as well as discusses current disputes and future concerns. It analyses how and why existing transboundary river water sharing treaties between India and its South Asian riparian neighbours are confronted with challenges. The book indicates that India's transboundary river water disputes with its South Asian riparian neighbours are likely to escalate in coming years due to the widening of the demand-supply gap in the respective countries. It further shows the impact of bilateral relations on the resolution of transboundary river water disputes, even as cordial relationships do not always guarantee the absence of river water disputes between riparian states. The book looks at some key questions: How political are India's transboundary rivers water disputes in South Asia? Why do the roots of India's river water disputes with Bangladesh and Pakistan lie in the partition of the British India in 1947? Why are there reservations against India's hydroelectricity projects or allegations of water theft? Is it possible to resolve transboundary river water disputes among these South Asian countries? This book will greatly interest scholars and researchers working in the areas of river management, environmental politics, transnationalism, water resources, politics and international relations, security studies, peace and conflict studies, geopolitics, development studies, governance and public administration, and South Asian studies in addition to policymakers and journalists.

Knowing how to manage the losses from water supply networks and how to get to the next level in bettering your system is a major problem and one that is most common in the majority of water companies worldwide. Sometimes water companies set their sights too high and cannot deliver due to non-realistic targets setting. Of course this is considered or seen as a failure within the company or country when it is really just exceeding expectations of what can be delivered. The aim of System Losses from Water Supply Networks is to assist water companies to identify where they are on the 'water loss ladder' and what is required to move to the next level. The book will provide an understanding of what the water companies need to achieve and where they should be aiming for in their efforts to reduce water losses. The book provides useful and practical information on non-revenue water (NRW) issues and solutions enriched with relevant case studies.

Lessons can be learnt from the past; from time to time it is useful for practitioners to look back over the historical developments of their science. Hydrogeology has developed from humble beginnings into the broad church of investigatory procedures which collectively form the modern-day hydrogeologist's tool box. Hydrogeology remains a branch of the over-arching science of geology and today provides analysis of the sub-surface part of the water cycle within a holistic approach to problem solving. The History of Hydrogeology, is a first attempt to bring the story of the evolution of the science of hydrogeology together from a country- or region-specific viewpoint. It does not cover history to the present day, nor does it deal with all countries involved in groundwater studies, but rather takes the story for specific key countries up and until about the period 1975 to 1980. This is when hydrogeology was still evolving and developing, and in some areas doing so quite rapidly. The book has been written not only for practitioners of hydrogeology and hydrology but also for teachers and students to see the context of the evolution of the science around the globe. The History of Hydrogeology will also be of interest to science historians and all those interested in the role that individuals, institutes and nations have played over the years in defining modern day studies of groundwater.
