Soil and Water Contamination, Second Edition gives a structured overview of transport and fate processes of environmental contaminants. Dealing with all topics essential for understanding and predicting contaminant patterns in soil, groundwater and surface water, it contributes to the formation of a solid basis for adequate soil and water pollution control and integrated catchment management. A unique feature of this work is that it does not treat water and soil pollution as independent processes, but as components of an integrated whole. The core of this geoscientific approach is divided into four parts: • Introduction to the basics of soil and water contamination, such as the fundamentals of environmental pollution and chemistry and the basic properties of soil, groundwater and surface water. • Source, role, and behaviour of substances in soil and water, treating natural and anthropogenic sources of nutrients, heavy metals, radionuclides and organic pollutants as well as emerging substances of concern, their physico-chemical characteristics, behaviour, and toxicity. • Transport and fate of substances in soil and water, focusing on processes of transport, exchange and transformations like advection, dispersion, adsorption kinetics and biochemical decay. Special attention is paid to the mathematical description and modelling of these processes. • Patterns of substances in soil and water, explaining spatial and temporal patterns of pollutants in soil, groundwater, and surface water, illustrated by recent case studies from fundamental and applied research. This comprehensive, successful textbook, now in its second edition, has been conscientiously updated and extended and includes many case studies, examples and exercises sections, providing undergraduate and graduate students in the Earth and Environmental Sciences with all the material necessary for the study of soil and water contamination. In addition, it can serve as a useful source of information for professionals.

With the continuing increase in population, more people are sharing the finite resources of the urban watershed, resulting in new and increasingly complex interactions between humans and the environment. Environmental contamination is a chronic problem—and an expensive one. In urban areas, water and soil contamination poses a threat to public health and has implications for future development. Taking an interdisciplinary approach, Urban Watersheds: Geology, Contamination, and Sustainable Development offers a framework for those working to improve the urban environment and create sustainable urban watersheds. The book presents over 20 years of research and professional practice on urban watersheds from the fields of environmental geology, geochemistry, risk analysis, hydrology, and urban planning. The geological characteristics of urbanized watersheds along with the properties of their common contaminants are integrated to assess risk factors for soil, groundwater, and air. With a framework rooted in scientific knowledge, the authors demonstrate the benefits of scientifically informed planning and decision making, offering guidelines to improve watershed management practices as well as urban development and redevelopment practices. Suitable for use as a textbook and as a professional practice reference, the book includes case studies on successful and unsuccessful approaches to contaminant remediation as well as practical methods for environmental risk assessment. PowerPoint® presentations of selected portions of the book are available with qualifying course adoption.

Chittaranjan Ray, Ph. D. , P. E. University of Hawaii at Mãnoa Honolulu, Hawaii, United States Jürgen Schubert, M. Sc. Stadtwerke Düsseldorf AG Düsseldorf, Germany Ronald B. Linsky National Water Research Institute Fountain Valley, California, United States Gina Melin National Water Research Institute Fountain Valley, California, United States 1. What is Riverbank Filtration? The purpose ofthis book is to show that riverbank filtration (RBF) isa low-cost and efficient alternative water treatment for drinking-water applications. There are two immediate benefits to the increased use of RBF: Minimized need for adding chemicals like disinfectants and coagulants to surface water to control pathogens. Decreased costs to the community without increased risk to human health. Butwhat,exactly, isRBF? In humid regions, river water naturally percolates through the ground into aquifers (which are layers of sand and gravel that contain water underground) during high-flow conditions. In arid regions, most rivers lose flow, and the percolating water passes through soil and aquifer material until it reaches the water table. During these percolation processes, potential contaminants present in river water are filtered and attenuated. If there are no other contaminants present in the aquifer or ifthe respective contaminants are present at lower concentrations, the quality of water in the aquifer can be ofhigher quality than that found in theriver. In RBF, production wells — which are placed near the banks ofrivers —pump large quantities ofwater.

Global Deforestation provides a concise but comprehensive examination of the variety of ways in which deforestation modifies environmental processes, as well as the societal implications of these changes. The book stresses how forest ecosystems may be prone to nearly irreversible degradation. To prevent the loss of important biophysical and socioeconomic functions, forests need to be adequately managed and protected against the increasing demand for agricultural land and forest resources. The book describes the spatial extent of forests, and provides an understanding of the past and present drivers of deforestation. It presents a theoretical background to understand the impacts of deforestation on biodiversity, hydrological functioning, biogeochemical cycling, and climate. It bridges the physical and biological sciences with the social sciences by examining economic impacts and socioeconomic drivers of deforestation. This book will appeal to advanced students, researchers and policymakers in environmental science, ecology, forestry, hydrology, plant science, ecohydrology, and environmental economics.

An environmental interface is defined as a surface between two abiotic or biotic systems, in relative motion and exchanging mass, heat and momentum through biophysical and/or chemical processes. These processes fluctuate temporally and spatially. The book first treats exchange processes occurring at the interfaces between atmosphere and the surface of the sea, and atmosphere and land surface. These exchanges include the effect of vegetation, transport of dust and dispersion of passive substances within the atmosphere. Processes at the environmental interfaces of freshwater, such as gas-transfer at free-surfaces of rivers, advective diffusion of air bubbles in turbulent water flows and boundary-layers phenomena in vegetated open channels are also described. Finally, the book deals with the phenomena that affect transport of material to and from the surface of an organism, including molecular and turbulent diffusion. The relevant issues related to mass transfer to and from benthic plants and animals are further considered in detail. The book will be of interest to graduate students and researchers in environmental sciences, civil engineering and environmental engineering, (geo)physics and applied mathematics.

The main objective of the Water Framework Directive in the European countries is to achieve a “good status” of all the water bodies, in the integrated management of river basins. In order to assess the impact of improvement measures, water quality models are necessary. During the previous decades the progress in computer technology and computational methods has supported the development of advanced mathematical models for pollutant transport in rivers and streams. This book is intended to provide the fundamental knowledge needed for a deeper understanding of these models and the development of new ones, which will fulfil future quality requirements in water resources management. This book focuses on the fundamentals of computational techniques required in water quality modelling. Advection, dispersion and concentrated sources or sinks of contaminants lead to the formulation of the fundamental differential equation of pollutant transport. Its integration, according to appropriate initial and boundary conditions and with the knowledge of the velocity field, allows for pollutant behaviour to be assessed in the entire water body. An analytical integration is convenient only in one-dimensional approach with considerable simplification. Integration in the numerical field is useful for taking into account particular aspects of water body and pollutants. To ensure their reliability, the models require accurate calibration and validation, based on proper data, taken from direct measurements. In addition, sensitivity and uncertainty analysis are also of utmost importance. All the above items are discussed in detail in the 21 chapters of the book, which is written in a didactic form for professionals and students.
