"Cultural aversion to microbes, healthiness or desire for safe bathing, the applications for water disinfection are varied and the technologies used to achieve this goal are numerous. The authors looked at a simple solution to implement: the use of a reagent called performic acid. Consequently, more than two years of applied research, observations and analyzes were necessary to demonstrate its harmlessness towards the natural environment. The strength of the demonstration lies in the cross-vision of many researchers and scientists from different backgrounds who shared their studies and observations. The strength of this testimony also lies in the diversity of the application cases, including notable and sensitive receiving environments as different as the Seine, the Atlantic Ocean or the Venice lagoon. Through its intentions and results, this work is a step, moving forward the 2030 Agenda for Sustainable Development, particularly SDG 6 "clean water and sanitation" relying on the lever of SDG 17 "partnerships for the goals"." Denis Penouel, Deputy CEO in charge of Prospective
The past few years have seen the emergence of a growing, widespread desire in this country, and indeed everywhere, that positive actions be taken to restore the quality of our environment, and to protect it from the degrading effects of all forms of pollution-air, noise, solid waste, and water. Since pollution is a direct or" indirect consequence of waste, if there is no waste, there can be no pollution, and the seemingly idealistic demand for" zero discharge" can be construed as a demand for zero waste. However, as long as there is waste, we can only attempt to abate the consequent pollution by converting it to a less noxious form. In those instances in which a particular type of pollution has been recognized, three major questions usually arise: 1, How serious is the pollution? 2, Is the technology to abate it available? and 3, Do the costs of abatement justify the degree of abatement achieved? The principal intention of this series of books is to help the reader to formulate answers to the last two of the above three questions. The traditional approach of applying tried-and-true solutions to specific pollution problems has been a major factor contributing to the success of environmental engineering, and in large measure has accounted for the establishing ofa "methodology of pollution control.
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.
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.
Water is essential to our planet's life, and protecting our water resources is a prerequisite for building a sustainable future. Since water use is inextricably linked to energy use, however, we face significant challenges. Water plays an essential role in many, if not most, manufacturing facilities. In a world facing a water-scarcity crisis, much research and development currently focuses on decreasing industries' water-use footprint. This compendium volume looks briefly at several select industries and investigates various water treatment processes for each, including microbial biotechnologies, ozone-related processes, adsorption, and photochemical reactions, among others. The various industries are organized into four groups: Industries that produce petrochemicals Metal industries The semi-conductor industry The paper and pulp industries Collected by a well-respected expert in the field, the studies gathered here are intended to be a starting point for further investigation by graduate students and other scientific researchers. Today's research, found in these chapters, can be expanded to create tomorrow's even wider frame of study.
This book discusses the development of useful models and their applications in soil and water engineering. It covers various modeling methods, including groundwater recharge estimation, rainfall-runoff modeling using artificial neural networks, development and application of a water balance model and a HYDRUS-2D model for cropped fields, a multi-model approach for stream flow simulation, multi-criteria analysis for construction of groundwater structures in hard rock terrains, hydrologic modeling of watersheds using remote sensing, and GIS and AGNPS.
This book provides essential background knowledge on a wide range of hydrological processes governing contaminant transport from soil to surface water across a range of scales, from hillslope to watershed. The mathematical description of these processes is based on both well-known and unique analytical solutions of different initial and boundary problems (primarily using methods from the kinematic wave theory and the reservoir/lumped-parameter concept), supported by numerical modelling studies. Some research topics, in particular several case studies, are illustrated by monitoring and experimental data analysis to show the importance of the research's applications in environmental practice and environmental education. Specific results concern the recognition of: (a) the effect of transient rainfall-runoff-infiltration partitioning on the chemical response of drainage areas to excess precipitation under certain field conditions related to the soil, hillslope characteristics, and contaminant properties; (b) soil erosion as a key factor that enhances the potential of adsorbed chemical transport in runoff; and (c) common tendencies in radionuclide behaviour in the near-surface environment contaminated by radioactive fallout from the Chernobyl (1986), Fukushima (2011) and the less known Kyshtym (1957) accidents, as well as from nuclear weapon tests in the atmosphere since 1952. The book's goal is to provide a conceptual foundation enabling readers to apply scientific knowledge to solve practical problems in environmental hydrology and radiology. More specifically, the book presents the state-of-the-art approaches that scientists and natural resources experts need in order to significantly improve the prediction of changes in the soil-water system chemistry due to human activities.
This book demonstrates how Morocco and other semi-arid countries can find solutions to water scarcity by rediscovering traditional methods of water resource management. The book begins by examining indigenous water heritage, considering the contribution of Islam and the mixed influences of Greek and Roman, Middle Eastern, Andalusian and Berber cultures. It then provides a thorough examination of resource management practices in Morocco throughout history, tracing the changing patterns from the instillation of agrarian capitalism in the 19th century, through the Protectorate years (1912-1956), to the 21st century. The book explains how reviving and modernizing traditional methods of water management could provide simple, accessible, and successful methods for addressing 21st century challenges, such as water scarcity and climate change. The work concludes by highlighting how these indigenous practices might be used to provide real-world practical solutions for improving water governance and therefore developing sustainable water management practices. Reviving Indigenous Water Management Practices in Morocco will be of great interest to students and scholars interested in water resource management, indigenous peoples, traditional knowledge, and sustainable development.

Playing with Fire chronicles the ongoing struggle facing Louisiana families trying to live and work against the backdrop of corrupt politicians and corporate greed. However, the story presented here is relevant wherever low-income, disenfranchised people are not included in decisions about their health and environment. This book examines the tale of Marine Shale Processors, the world's largest hazardous waste company, and the women who fought to protect their community and their children. The lesson here is that a dedicated group of people fighting for what is right can win and it serves as an example for any community that wants to determine what their own environmental future. Playing with Fire is a well-documented account that provides lessons for communities, government agencies, and corporations. It dispels the narrative that low-income communities must settle for jobs at the expense of clean air and water and politicians and demonstrates that corporations that further trample on the rights of people will ultimately pay the price.

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.
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. Note: T& F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka. This title is co-published with New India Publishing Agency.
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.
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.
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.
