Cyanobacteria, or blue-green algae, commonly occur in a variety of water types throughout the world. A variable, but, high proportion of the cyanobacterial blooms and scums, which can develop annually in lakes, reservoirs, canals and slow-flowing rivers, contain potent toxins. Although animal poisonings and human health problems associated with the ingestion of, or contact with, cyanobacterial scums have long been recognized, a developing understanding of the health hazards posed by the toxins requires that reliable, sensitive, specific and convenient methods are available for their detection and quantification.
Detection methods for cynobacterial toxins looks at the application of biological, toxicological, biochemical and physicochemical techniques in studies of cyanobacterial toxins and at experimental methods that have identified at least 50 cyanobacterial compounds toxic to vertebrates.
Academics, public health bodies, environmental protection agencies and water companies are all involved in monitoring cyanobacterial levels and effects, and this book will help to ensure that their research is not duplicated, is standardized and comparable, and that optimal progress can be made in an important area that is still in its developing stages.

Natural saline water, waste water, and irrigation return flow endanger the groundwater aquifers in the Rift. In the long run this will ruin the socio-economic backbone of the settlements in the area. Sustainability of the water resources will only be achieved when the process of water replenishment and its underground flow is understood and water extraction is regionally controlled. Rare earth element and spider patterns are presented as new tools for studying the hydrology. Progress in 3-D modelling of groundwater flow proved successfully the impact of pumping on the surroundings of wells and overexploitation of aquifers.

This book explores creative interdisciplinary and potentially transformative solutions to the current stalemate in contemporary water policy design. A more open policy conversation about water than exists at present is proposed - one that provides a space for the role of the imagination and is inclusive - of the arts and humanities, relevant stakeholders, including landholders and Indigenous peoples, as well as science, law and economics. Written for a wide audience, including practitioners and professional readers, as well as scholars and students, the book demonstrates the value of multiple disciplines, voices, perspectives, knowledges and different ways of relating to water. It provides a fresh and timely response to the urgent need for water policy that works to achieve sustainability, and may be better able to resolve complex environmental, social and cultural water issues. Utilising a broad range of evidentiary sources and case studies from Australia, New Zealand, Canada and elsewhere, the authors of this edited collection demonstrate how new ways of thinking and imagining water are not only possible but already practised, and growing in saliency and impact. The current dominance of narrower ways of conceptualising our relationship with water is critiqued, including market valuation and water privatisation, and more innovative alternatives are described, including those that recognise the importance of place-based stories and narratives, adopt traditional ecological knowledge and relational water appreciations, and apply cutting-edge behavioural and ecological systems science. The book highlights how innovative approaches drawing on a wide range of views may counter prevailing policy myopia, enable reflexive governance and transform water policy towards addressing water security questions and the broader challenges posed by the Anthropocene and the UN Sustainable Development Goals.

Dr. Hossen carried out an exceptional program of research in Bangladesh which focused on water governance in relation to human rights, international water law and environmental sustainability. His major argument is that eco-agricultural system encounters major disruptions due to a number of factors including regional hydropolitics and neoliberal and highly centralized approaches to water resource management that follow the principles of "ecocracy." In this context, Dr. Hossen explores three major questions: (i) How can local ecological knowledge be incorporated into national water policy? (ii) What strategies and reforms are required at the international watershed governance level? and (iii) How can human rights principles, including the principle of water as a human right, be used to formulate more effective water policy and governance principles? To answer these questions, Dr. Hossen explores the effects of regional hydropolitics on water management, focusing on three large engineering projects, the Farakka Barrage built by India on the Ganges River, and the Ganges-Kobodak (GK) and Gorai River Restoration (GRR) Projects in Bangladesh. This analysis is based on his research into local knowledge and farming practices during a year of fieldwork in 2011-12, focus group discussions, in-depth case studies and social survey methods. In addition to this primary data, he looks at extensive secondary documents from the government of Bangladesh pertaining to water management, agricultural modernization and institutional structures. The arguments herein are applicable particularly to the Ganges-Brahmaputra Basin countries in South Asia but also to the river basins of other parts of the world.

As we transition into the 21st century, it is apparent that this is an exciting time for environmental engineers and scientists studying remediation technologies. There has been a rapid development of new ways to clean-up polluted groundwater. Research activities of the past and next 10 years will have a dramatic impact on the quality of the subsurface environment for the next century. In 20, or even 10 years from now, our approach to subsurface remediation will probably be vastly different than it is today. Many of the emerging technologies presented in this book will form the basis of standard remediation practices of the future. Physicochemical Groundwater Remediation presents detailed information on multiple emerging technologies for the remediation of the contaminated subsurface environment. All of these technologies apply our knowledge of physical and chemical processes to clean up ground water and the unsaturated zone, and many (if not all) of these emerging technologies will help define standard practices in the future. These technologies include in situ sorptive and reactive treatment walls, surfactant-enhanced aquifer remediation, optimization analyses for remediation system design, chemical, electrochemical, and biochemical remediation processes, and monitored natural attenuation. You will learn how palladium catalyzes the dehalogenation of chlorinated solvents. You will find out how barometric pumping can naturally remove significant quantities of volatile organic pollutants from shallow ground water and the unsaturated zone. You can learn about mobilizing non-aqueous phase liquids (NAPLs) without risking significant downward migration of the NAPL. You can find out how processes such as electroosmosis and electromigration can be exploited for groundwater remediation purposes and how zero-valent iron and zeolite treatment walls can be used in situ to treat and control contaminant plume migration. Contributors to this book are experts in groundwater remediation processes, and they represent industry, consulting, academia, and government. If your work involves the clean up of contaminated soil and groundwater, this book is an essential reference to keep you up to date on the most promising new developments in remediation research.

This volume provides a comprehensive overview of environmental aspects of the Sava River, which is the greatest tributary to the Danube River and the major drainage river system of South Eastern Europe. Hydroelectric power plants, river traffic, intensive agricultural activities, heavy industry and floods have considerable influence on the environment and biota in the basin. Summarizing the results that were gathered in the course of EU, bilateral and national projects, the book highlights the most important stressors and helps readers to better understand the impact of anthropogenic activities on the function of river basins. Topics include: transboundary water cooperation between the riparian countries; climate change projection, including its impact on flood hazards; evaluation of anthropogenic pollution sources; pollution of sediments, metal bioavailability and ecotoxicological and microbiological characterization of the river. The biological part also addresses quality aspects related to wildlife in river aquatic ecosystems (algae, macrophytes, zooplankton, macroinvertebrates and fish) and riparian ecosystems (amphibians, reptiles, birds and mammals). The general state of biodiversity and pressures caused by invasive aquatic species are also discussed.

This study presents a unique way to utilize the existing literature to explain the success of treaties in managing hydrologic stress. Literature-derived core concepts are summarized as seven treaty mechanisms categories (specificity, uncertainty management, enforcement, communications, flexibility, integrativeness, and scale) and are hypothesized as important for shaping the institutional resiliency of a treaty. Treaty design is shown to have a relevant and important role in shaping basin management so that nations may better achieve their goals in a changing climate.

Heavy metals always pose serious ecological risks when released into the environment due to their elemental non-degradable nature, regardless of their chemical form. This calls for the development of efficient and low-cost effluent treatment and metal recuperation technologies for contaminated waste water, not only because regulatory limits need to be met but also because the waste itself can be a resource for certain precious metals.

Biosorption is a general property of living and dead biomass to rapidly bind and abiotically concentrate inorganic or organic compounds from even very diluted aqueous solutions. As a specific term, biosorption is a method that utilizes materials of biological origin - biosorbents formulated from non-living biomass - for the removal of target substances from aqueous solutions. Recent research on biosorption provides a solid understanding of the mechanism underlying microbial biosorption of heavy metals and related elements.

This book gathers review articles analyzing current views on the mechanism and (bio)chemistry of biosorption, the performance of bacterial, fungal and algal biomass, and the practical aspects of biosorbent preparation and engineering. It also reviews the physico-chemical evaluations of biosorbents and modelling of the process as well as the importance of biosorption during heavy metal removal using living cells. It is a reference work for scientists, environmental safety engineers and R&D specialists who wish to further promote biosorption research and use the accumulated knowledge to develop and build industrial applications of biosorption in heavy metal separation technologies.

This book aims at stimulating discussion between researchers working on state of the art approaches for operational control and design of transport of water on the one hand and researchers working on state of the art approaches for transport over water on the other hand. The main contribution of the book as a whole is to present novel perspectives ultimately leading to the management of an envisioned unified management framework taking the recent advances from both worlds as a baseline. The book is intended to be a reference for control-oriented engineers who manage water systems with either or both purposes in mind (transport of water, transport of goods over water). It highlights the possible twofold nature of water projects, where water either acts as primary object of study or as a means. The book is dedicated to comparing and relating to one another different strategies for (operational) management and control of different but strongly related systems in the framework of the water. In that sense, the book presents different approaches treating both the transport of water and transport over water. It compares the different approaches within the same field, highlighting their distinguishing features and advantages according to selected qualitative indices, and demonstrates the interaction and cross-relations between both fields. It will also help to determine the gaps and common points for both fields towards the design of such a unifying framework, which is lacking in the literature. Additionally, the book looks at case studies where the design of modeling/control strategies of either transport of water or transport over water have been proposed, discussed or simulated.

This book addresses questions of relevance to governments and industry in many countries around the world, in particular concerning the link between contaminated-land-management programs and the protection of drinking water resources and the potential effects of climate changes on the availability of these same resources. On the "problem" side, it reports and analyzes methodologies and experiences in monitoring and characterization of drinking water resources (at basin, country and continental scales), pollution prevention, assessment of background quality and of impacts on safety and public health from land and water contamination and impacts of climate change. On the "solution" side, the book presents results from national cleanup programs, recent advances in research into groundwater and soil remediation techniques, treatment technologies, research needs and information sources, land and wastewater management approaches aimed at the protection of drinking water.

For the first time, here is a book that focuses on in vitro approaches to the study of the toxicology of polluting agents (including heavy metals, radionuclides, micro-organics, estrogenic compounds, and complex mixtures) in the aquatic environment. The importance of in vitro methods is that they allow standardised techniques to be developed and validated for substance and species specific experiments in a controlled way. Also, they allow mechanistic studies without the problems of individual variation between animals and environmental stress.
