Available in PDF, EPUB and Kindle. Book excerpt: Contaminated bottom sediments and their negative impacts on water quality are a major problem in surface waters throughout the United States as well as in many other parts of the world. Even after elimination of the primary contaminant sources, these bottom sediments will be a main source of contaminants for many years to come. In order to determine environmentally-effective and cost-effective remedial actions, the transport and fate of these sediments and associated contaminants must be understood and quantified. This book details how to best approach contaminated sediments, allowing readers to better assess and address water quality and health issues, water body management, and potential remediation methods. Understand and Address Major Environmental Threats to Our Water Sediment and contaminant transport is an enormously rich and complex field that involves physical, chemical, and biological processes as well as the mathematical modeling of these processes. While many books have been written on these broad topics, Sediment and Contaminant Transport in Surface Waters takes a more focused approach, highlighting areas that have been investigated but not covered thoroughly elsewhere. This volume emphasizes the erosion, deposition, flocculation, and transport of fine-grained, cohesive sediments; the effects of finite rates of sorption on the transport and fate of hydrophobic contaminants; and the effects of major events such as floods and storms. Despite these emphases, the overall goal of the text is to present a general description and understanding of the transport of sediments and contaminants in surface waters as well as procedures to quantitatively predict this transport.

Book excerpt: Transport and Transformation of Contaminants Near the Sediment-Water Interface addresses the issue of contaminated bottom sediments and their potential adverse impacts on water quality. This state-of-the-science book covers regulatory management perspectives, physical processes, chemical and biological processes, and process synthesis/modeling. Specific topics discussed include EPA's Sediment Quality Criteria program from a regulatory perspective; flocculation, deposition, and resuspension of fine-grained sediments; approaches for measuring vertical sediment flux near the sediment-water interface; equilibrium models for metal speciation in natural sediments; the partitioning of organic chemicals in bottom sediments; and the development and application of models of sediment and associated contaminant transport in surface waters. The significance of recent studies suggesting that interaction of contaminated bottom sediments with the overlying water play an important role in the long-term recovery of aquatic systems makes Transport and Transformation of Contaminants Near the Sediment-Water Interface essential for water quality engineers, environmental chemists, and environmental toxicologists. The volume provides important information for consultants, regulators, researchers, and graduate students as well.

Book excerpt: The world's first nuclear bomb was a developed in 1954 at a site near the town of Los Alamos, New Mexico. Designated as the Los Alamos National Laboratory (LANL) in 1981, the 40-square-mile site is today operated by Log Alamos National Security LLC under contract to the National Nuclear Security Administration (NNSA) of the U.S. Department of Energy (DOE). Like other sites in the nation's nuclear weapons complex, the LANL site harbors a legacy of radioactive waste and environmental contamination. Radioactive materials and chemical contaminants have been detected in some portions of the groundwater beneath the site. Under authority of the U.S. Environmental Protection Agency, the State of New Mexico regulates protection of its water resources through the New Mexico Environment Department (NMED). In 1995 NMED found LANL's groundwater monitoring program to be inadequate. Consequently LANL conducted a detailed workplan to characterize the site's hydrogeology in order to develop an effective monitoring program. The study described in Plans and Practices for Groundwater Protection at the Los Alamos National Laboratory: Final Report was initially requested by NNSA, which turned to the National Academies for technical advice and recommendations regarding several aspects of LANL's groundwater protection program. The DOE Office of Environmental Management funded the study. The study came approximately at the juncture between completion of LANL's hydrogeologic workplan and initial development of a sitewide monitoring plan.

Book excerpt: Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.

This book was released on 2007 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydro-system within a watershed includes many environmental processes, such as rainfall, runoff, groundwater flow, infiltration, evapotranspiration, recharge, upland erosion, sediment transport, and contaminant transport. In order to investigate these processes and evaluate their effects on water environments, numerical models have been recognized as an increasingly efficient and effective tool. Due to the natural intrinsic connections between surface and subsurface waters, modeling of flow, upland soil erosion, and contaminant transport should be considered as an integrated system. This dissertation has developed a physically-based integrated numerical model for flow, sediment, and contaminant transport in the surface-subsurface system. In this model, the surface flow is calculated using a depth-averaged 2-D diffusion wave model, and the variably saturated subsurface flow is computed using the 3-D mixed-form Richards equation. Interactions between surface and subsurface flows are considered using the continuity conditions of the pressure head and exchange flux at the ground surface. A general form of the surface flow equation based on the diffusion wave approximation is developed, which is intrinsically coupled with the variably saturated subsurface flow equation. The upland soil erosion and transport model employs the concept of nonequilibrium that considers both erosion and deposition. The model simulates nonuniform total-load sediment transport, with detachments from rainsplash and/or hydraulic erosion driven by overland flow. Contaminant transports in both surface and subsurface domains are described using advection-diffusion equations. The model considers the sediment sorption and desorption of the contaminant, as well as contaminant exchanges between surface and subsurface due to infiltration, diffusion, and bed change. The integrated numerical model is evaluated by simulating several published laboratory- and field-scale experiments. It is further applied to compute flow discharge, sediment and pesticide concentration during storm events in the Deep Hollow Lake watershed, Mississippi. The sensitivity analysis of the model is also performed using different values for several model parameters. The results have shown that the integrated model framework is capable of simulating the rainfall-runoff related hydrological processes in natural surface-subsurface systems.

Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides an overview of transport and fate processes of environmental contamination, in such a way that the reader can both understand and predict contaminant patterns in soil, groundwater, and surface water. In contract to most existing texts, soil and water pollution are treated as integrated environmental matter from a geographical/spatial perspective at point, local, regional, and catchment scales. The spatial approach links up with recent developments and trends in environmental legislation and other integrated catchment management initiatives. It consists of four coherent parts: 1. Introduction to soil and water contamination; 2. Source, role, and behavior of substances in soil and water; 3. Transport and fate processes of substances in soil and water; and 4. Patterns of substances in soil and water. Intended for undergraduate and graduate students in Earth and Environmental Sciences, who understand the fundamentals of chemistry, hydrology and soil science; may also serve as a useful reference for professionals.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
