This is the time when legacy, pathogenic, and emerging contaminants must be talked about, understood, and dealt with together. While the geogenic contamination of the groundwater is a well-established phenomenon that is considered as legacy contaminants that risk people's health globally, both pathogenic and emerging contaminants like various water-borne pathogens and pharmaceutical personal care products (PPCPs) are becoming imperative for their acute and chronic toxic effects. While contaminated groundwater consumption leads to skin pigmentation, hyperkeratosis, kidney damage, cardiovascular disease, and children's overall development, poor sanitation-related pathogenic microorganisms cause a significant number of child and prenatal deaths. Simultaneously, antibiotic microbial resistance (AMR) is expected to kill 100 million people by 2050. However, there are rare texts that combine aspects of all these three under a single book cover.This book gives an understanding of the occurrence, fate, and transport of geogenic, microbial, and anthropogenic contaminants in the groundwater. It covers not only the scientific and technical aspects but also environmental, legal, and policy aspects for contaminant management in the environment under the paradigm shift of COVID-19. This book is intended to bring the focus on the natural contaminants—biotic or abiotic—in the post-COVID Anthropocene, which is illustrating a significant alteration of systems and the subsequent downstream impacts owing to globalization. This book has compiled global work on emergence, mass flow, partitioning, and activation of geogenic, emerging, and pathogenic contaminants in various spheres of environment with special emphasis on soil, sediment, and aquatic systems for enhancing the understanding on their migration and evolution for the welfare of mankind.

In the modern world, industries and factories are rising exponentially. This has led to the mass cultivation of non-biodegradable products, like heavy metals, that have polluted the environment and become a major threat to plant growth, crop yield, and human health. Conventional remediation technologies are expensive and may not remove contaminates effectively. Therefore, it is important to develop economically practical and more effective methods to decontaminate soils. Nano-Phytoremediation Technologies for Groundwater Contaminates: Emerging Research and Opportunities is a collection of innovative research on the methods and applications of the use of plants for remediating metal-contaminated soil and water.

The author describes the economic implications of groundwater pollution and its control and exemplifies with a real case study.

Arsenic-contaminated groundwater is considered one of the world's largest environmental health crises, as more than 300 million people in more than one-third of countries worldwide are at risk of groundwater arsenic poisoning. This book addresses how arsenic in groundwater impacts human health by using the frameworks of natural sciences, social sciences, and health sciences in the context set by environmental and legal considerations. Arsenic in Groundwater: Poisoning and Risk Assessment examines the spatial, quantitative, and qualitative aspects on arsenic poisoning; for instance, using geographical information systems (GIS) to investigate the spatial discontinuity of arsenic-laced water in spatial and temporal dimensions to uncover patterns of variations over scales from meters to kilometers. Spatial risk mapping provides insight for academics, researchers, policy makers, and politicians on possible long-term strategies for arsenic mitigation. Qualitative methodological approaches uncover the hidden issues of arsenic poisoning on human health and the related social implications. The book also examines legal aspects, such as the right to safe drinking water, as well as an in-depth look at how community participation can shape public policy. Features: Describes arsenic poisoning from both the scientific and social science perspectives Includes technical insights drawn from GIS-based modeling for spatial arsenic discontinuity and spatial health risks of arsenic poisoning Provides a state-of-the-art review of the human health literature and cutting-edge scientific evidence for arsenic-related health and social implications Examines the environmental justice and legal issues of drinking water and its quality Presents environmental policy and public mitigation strategies with Public Participation GIS (PPGIS) related to arsenic contamination More than 2,000 references serve as valuable resources for various aspects of arsenic poisoning

The rapid progression of technology has significantly impacted population growth, urbanization, and industrialization in modern society. These developments, while positive on the surface, have created critical environmental problems in recent years. Biostimulation Remediation Technologies for Groundwater Contaminants is a critical scholarly publication that examines the release of heavy metals into the environment as a result of human activities and the use of nanoparticles and other technologies to manage and treat the effects of the pollution. Featuring coverage on a broad range of topics such as toxicity of heavy metals, bioremediation, and acclimated bacterial strains, this book is geared toward environmentalists, engineers, academics, researchers, and graduate-level students seeking current research on bioremediation as an alternate way to manage or degrade heavy metal waste.

This book represents the first comprehensive reference volume available on subsurface transport and fate processes. The volume is organized into four sections covering the basics of contaminant properties and how they affect transport and fate, the fundamental processes affecting subsurface transport and fate of contaminants, applications of transport and fate information to various contaminant types, and utilization of transport and fate information for predicting contaminant behavior. Specific topics such as traditional hydrodynamic processes of advection and dispersion, facilitated transport and contaminant flushing, and individual ground water contaminants are also explored in detail. Subsurface Transport and Fate Processes is ideal for environmental and ground water consultants, regulatory agency personnel, and educators in geology, hydrogeology, civil engineering, and environmental engineering.

Groundwater contamination is nearly always the result of human activity. In areas where population density is high and human use of the land is intensive, ground water is especially vulnerable. Virtually any activity whereby chemicals or wastes may be released to the environment, either intentionally or accidentally, has the potential to pollute groundwater. When groundwater becomes contaminated, it is difficult and expensive to clean up. This book focuses on the performance, limitations and impacts of groundwater contamination.

Written by one of the world's foremost authorities on the subject, this is the most comprehensive and in-depth treatment available to environmental engineers and scientists for the remediation of groundwater, one of the earth's most precious resources. Groundwater is one of the Earth's most precious resources. We use it for drinking, bathing, and many other purposes. Without clean water, humans would cease to exist. Unfortunately, because of ignorance or lack of caring, groundwater is often contaminated through industrialization, construction or any number of other ways. It is the job of the environmental engineer to remediate the contaminated groundwater and make what has been tainted safe again.Selecting the proper remediation strategy and process is the key to moving forward, and, once this process has been selected, it must be executed properly, taking into consideration the costs, the type of contaminants that are involved, time frames, and many other factors. This volume provides a broad overview of the current and most widely applied remedial strategies. Instead of discussing these strategies in a generic way, the volume is organized by focusing on major contaminants that are of prime focus to industry and municipal water suppliers. The specific technologies that are applicable to the chemical contaminants discussed in different chapters are presented, but then cross-referenced to other chemical classes or contaminants that are also candidates for the technologies. The reader will also find extensive cost guidance in this volume to assist in developing preliminary cost estimates for capital equipment and operations & maintenance costs, which should be useful in screening strategies. The eight chapters cover all of the major various types of contaminants and their industrial applications, providing a valuable context to each scenario of contamination. This is the most thorough and up-to-date volume available on this important subject, and it is a must-have for any environmental engineer or scientist working in groundwater remediation.

This new edition adds several new chapters and is thoroughly updated to include data on new topics such as hydraulic fracturing, CO2 sequestration, sustainable groundwater management, and more.

Groundwater is a major concern for the human community as it is the most important and reliable source of freshwater supply on earth. It is a renewable and finite natural resource, vital for man's life, socio-economic development and it is a valuable component of the ecosystem. However, groundwater is vulnerable to both natural and human impacts. An aquifer is an underground porous rock formation which allows water to move through it. Water wells are drilled through aquifers for easier access to groundwater in many areas and is sometimes the only access to fresh water. This book discusses the properties, roles, and provides further new research on aquifers.

In The Netherlands, Belgium and other European countries, manganese is removed by conventional groundwater treatment with aeration and rapid (sand) filtration. Such a treatment process is easy to operate, cost effective and sustainable, because it does not make use of strong oxidants such as O3, Cl2, ClO2 and KMnO4 with the associated risk of by-product formation and over or under dosing. However, application of aeration-filtration is also facing drawbacks, especially the long ripening time of filter media. Due to the long ripening time, water companies have to waste large volumes of treated water, making this process less sustainable. Also, costs associated with filter media ripening (man power, electricity, operational and analysis costs) are high. Therefore decreasing the filter ripening time, regarding manganese removal is a big issue. Although already extended research has been carried out into manganese removal, the controlling mechanisms, especially of the start up face of filter media ripening, are not fully understood yet. The emphasis of this thesis is to provide a better understanding of the mechanisms involved in the ripening of virgin filter media, regarding manganese removal and how to shorten or completely eliminate the long ripening period of filters with virgin material. This thesis therefore highlights the role of the formation of a manganese oxide coating on virgin filter media. Characterization and identification revealed that the responsible manganese oxide for an effective manganese removal was Birnessite. It was found that Birnessite, formed at the beginning of the ripening process was of a biological origin. Based on the knowledge that manganese removal in conventional groundwater treatment is initiated biologically, long ripening times may be reduced by creating conditions favouring the growth of manganese oxidizing bacteria, e.g., by limiting the back wash frequency and / or intensity. Additionally, this thesis also shows that the use of freshly prepared manganese oxide, containing Birnessite, can completely eliminate filter media ripening time.

Ein Ausfall der öffentlichen Trinkwasserversorgung im Zusammenhang mit einem großflächigen, längerfristigen Stromausfall stellt eine Bedrohung für nahezu die gesamte Bevölkerung dar. Das Grundproblem stellt die Abhängigkeit der Trinkwasserversorgung von der Energieversorgung dar. Stoffe, welche bereits im Routinebetrieb im Rohwasser vorhanden sind, könnten im Blackout eventuell nicht mehr fachgerecht entfernt werden. Analyselabore sind nicht auf einen Stromausfall vorbereitet. Käme es neben Unfällen auch noch zu kriminellen Einträgen von CBRN Stoffen (chemisch, biologisch, radioaktiv oder nuklear) ins Trinkwassersystem, so wäre dies weder vom Betreiber noch vom Verbraucher festzustellen. Während der Zeit eines Blackouts kann die Quantität und die Qualität des Trinkwassers eingeschränkt werden. Eine flächendeckende Versorgung durch Aufbereitungsanlagen der Einsatzorganisationen ist nicht möglich. Die physische und psychische Belastung durch Wassermangel oder Schadstoffbelastungen könnte zu einer Schwächung des Immunsystems führen. In der vorliegenden Studie werden mögliche Maßnahmen zur Sicherstellung der Trinkwasserversorgung in der Zivilbevölkerung während eines Blackouts untersucht.

The pollution of soil and groundwater by heavy metals and other chemicals is becoming a serious issue in many countries. However, the current bioremediation processes do not often achieve sufficient remediation, and more effective processes are desired. This book deals with advances in the bioremediation of polluted soil and groundwater. In the former chapters of this book, respected researchers in this field describe how the optimization of microorganisms, enzymes, absorbents, additives and injection procedures can help to realize excellent bioremediation. In the latter chapters, other researchers introduce bioremediation processes that have been performed in the field and novel bioremediation processes. Thus, the readers will be able to obtain new ideas about effective bioremediation as well as important information about recent advances in bioremediation.

Contamination of groundwater sources is a global phenomenon and it's becoming evident that unregulated human activity will lead to further deterioration of the resource in many countries of the world. There is therefore an increasing need for research and informed policies to strategically manage groundwater along with other natural resources. This book has been structured into ten chapters, including an introductory background and contextual material for its contributions, with case studies from US, Canada, Australia, Brazil, Serbia, India, Malaysia, Netherlands, and South Africa. Contributions in this book range from hydrogeochemical investigations and evaluation of groundwater usability for water supply as well as for agricultural purposes to groundwater quality descriptions and characterisation. Issues on groundwater overdevelopment and the consequent quality degradation; flow and recharge processes with management implications; groundwater dependent ecosystems and ecological implications are well covered in its content. A number of simulation variants from numerical modelling to characterise groundwater conditions and estimate groundwater resources potential in large basins are presented to support technical decisions and policy making. The prospects and problems of groundwater development are addressed in this book and novel bioremediation technology with more than 10 years of successful application in remediating groundwater contaminated with chlorinated aliphatic hydrocarbons (CAHs) concludes the content. This book will be useful to all within the groundwater community, researchers and policy makers alike.

In this updated and expanded second edition, new literature has been added on contaminant fate in the soil-subsurface environment. In particular, more data on the behavior of inorganic contaminants and on engineered nanomaterials were included, the latter comprising a group of “emerging contaminants” that may reach the soil and subsurface zones.New chapters are devoted to a new perspective of contaminant geochemistry, namely irreversible changes in pristine land and subsurface systems following chemical contamination. Two chapters were added on this topic, focusing attention on the impact of chemical contaminants on the matrix and properties of both liquid and solid phases of soil and subsurface domains. Contaminant impacts on irreversible changes occurring in groundwater are discussed and their irreversible changes on the porous medium solid phase are surveyed. In contrast to the geological time scale controlling natural changes of porous media liquid and solid phases, the time scale associated with chemical pollutant induced changes is far shorter and extends over a “human lifetime scale”.

Boden- und Grundwasserkontaminationen verursachen erhebliche Kosten, da aufwändige Sanierungen nicht nur Unternehmen, sondern oft auch die gesamte Volkswirtschaft belasten. Moderne In-situ-Verfahren verfolgen das Konzept, Schadstoffe in Böden und Grundwasser vor Ort in ungefährliche Stoffe umzusetzen. Durch Zugabe von Reagenzien werden Schadstoffe im Untergrund abgebaut oder in eine mobile, extrahierbare Form überführt. Doch nur mit dem nötigen Know-How lassen sich die Sanierungsverfahren auch effizient umsetzen. Mit diesem Buch werden die Grundlagen erarbeitet, die es ermöglichen, eine Boden und Grundwassersanierung zu planen, zu überwachen und erfolgreich zu beenden. Biogeochemische und physikalische Prozesse, die im kontaminierten Untergrund ablaufen, werden umfassend erläutert. Mit ingenieurtechnischem Ansatz und basierend auf der industriellen Praxis werden verschiedene Verfahren vorgestellt und unter sozioökonomischen und nachhaltigen Gesichtspunkten betrachtet. Denn nur wenn der gesamte Sanierungsprozess in idealer Weise durchlaufen wird, sind kostengünstige und umfassende Lösungen möglich. Ein unverzichtbarer Begleiter für Umweltbehörden und Umweltingenieure, aber auch gleichermaßen geeignet für Studenten der Chemie und Umweltwissenschaften. Aus dem Inhalt: • Schadstofftransport • Konzeptionelles Standortmodell • Sanierungsstrategie • Quellensanierung • Injektionstechniken • Mikrobielle Sanierungsverfahren • Chemischer Abbau und in situ chemische Oxidation (ISCO) • Arbeitsschutz und Arbeitssicherheit

Calcium and magnesium are abundant in groundwater, but the role of groundwater as the essential source of these important nutrients is very often neglected. Hydrogeochemical studies have focused mainly on the distribution and behaviour of constituents that cause deterioration of water quality, such as: nitrate, nitrite or iron and manganese. Theref

In the past decades, environmental scientists, economists and physicists have been juggling critical issues within environmental strategies and environmental management styles in order to find a feasible medium between limited resources, long term demands and objectives, and interest groups. In the search for best management alternatives, practice has undergone a pendulum swing between stages that can be characterised as frontier economics, radical environmentalism, resource management/allocation, selective environmentalism and sustainable environmental management. The next stage of management must answer such questions as: `Can there be a global - uniform environmental strategy?', or `Based on their characteristics, can different issues, different regions and different applications have unique environmental strategies?'Based on this premise, the next stage of management may be identified as risk based sustainable environmental management. The goal of this style will be the risk based, long term, harmonious management of economic resources and environmental preservation for health, safety and prosperity of sustainable populations. When evaluation of risk or risk based ranking of management alternatives enter the picture as part of the overall puzzle, then social policy, ethics and health issues assume a very important role in the management strategy. Economic incentives and environmental constraints have to be considered harmoniously, the main emphasis being placed on protection and preservation of human health and the long term sustaining of populations.

This book explores the history, techniques, and materials used in the practice of induced hydraulic fracturing, one of today's hottest topics, for the production of natural gas, while examining the environmental and economic impact. You can't squeeze blood from a turnip, but you can release trapped natural gas from rock. At least that is what is being accomplished now throughout North America. Natural gas that is primarily methane has been proven to be an excellent fuel source. It can be safely burned to create heat to power engines, boilers in factories and homes as well as powering turbines for generating electricity. Projections on natural gas volumes trapped underground suggest a nearly inexhaustible supply of this product. Yet with such abundance comes controversy. A popular and economical technique relies on the gas from subterranean sources and requires fracturing rock bed. This process is actually carried out naturally every day with water or magma. Magma may flow into rock beds superheating water to generate steam. The resulting pressure of the expanding water molecules can be so great, it can lift and separate thousands of tons of rock deep beneath the Earth's surface. This same practice can be carried out artificially (induced) using high-powered pumps and various liquid compounds. This technique combined with new horizontal directional drilling machines have enabled the harvest and distribution of natural gas. But at what cost? Does this practice contribute to greenhouse gas? Does it create earthquakes? Does it contaminate the groundwater supply? These are important issues surrounding hydraulic fracturing, and they are covered here in detail.

Uranium has both radioactive and chemical hazards and risk assessments must address both types. Its environmental distribution depends on natural occurrence and has been influenced by human activities such as energy production, coal, and phosphate fertilizer exploration, which may impact freshwater ecosystems. In this book, the authors present current research in the study of the characteristics, occurrence and human exposure to uranium. Topics include the anthropogenic sources of uranium in Serbia; uranium mining in Portugal; laser-induced nuclear decays in uranium isotopes; uranium hydrothermal deposits; and geophysical studies to evaluate geological and hydro-geological features in old uranium mines.
