This technical note describes the application of appropriate physical, engineering, chemical, and biological tests described in Technical Note DOER-C2 (Winfield and Lee 1999) for characterizing and determining the potential for beneficial uses of dredged material in aquatic, wetland, and/or upland environments. The characterization and testing of a dredged material must be matched to a particular beneficial use. A number of physical, engineering, chemical, and biological tests have been described in Technical Note DOER-C2 (Winfield and Lee 1999) to characterize and aid in making decisions about the potential beneficial reuse of the dredged material. Appropriate characterization tests are listed in Tables 1 through 3. Normally, a sediment is tested and evaluated according to the USACEfU. S. Environmental Protection Agency (USEPA) (1992) prior to dredging and disposal. Those data can be used in the initial evaluation of potential beneficial uses of the dredged material, indicating, for example, the presence of contaminants. However, the placement of dredged material in a CPF and the physicochemical changes occurring in the dredged material can result in changes in relation to the nature and location of contaminants within the CPF. Normally, contaminants when present in the dredged material tend to be associated with the finer grain sized particles. Even though most of the tests identified in Tables 1 and 2 were initially designed for soils, they can be applied to dredged material because of its soil-like nature.
Authoritative, up-to-date guide to dredging theory and practice. From selecting the right equipment, to evaluating environmental impact, to bidding on a project, Handbook of Dredging Engineering, Second Edition, is the last word on modern hydraulic dredging. Edited by John B. Herbich, with contributions by well-know experts in the field, the Handbook examines basic fluid mechanics; dredge pumps; dredging equipment; sediment; pipeline transport of solids; dredging methods; disposal and placement of dredged material; numerical models for predicting the fate of dredged material placed in open water; environmental effects of dredging activities; instrumentation and automation; and project planning. This vital new edition covers major advances made over the last seven years. Three chapters are new to this edition: numerical models for predicting the fate of dredged material...subaqueous capping of contaminated sediment...and removal of contaminated sediments by dredging, with illustrative case studies.
This book covers the latest in recycling and reuse research focused toward greater sustainability and includes chapters authored by the world’s leading thinkers and practitioners in the field. Topics covered include recycling and reuse, solid waste management, renewable energy, environmental studies, and wastewater management. This text contains environmental issues with an experimental focus, making this a useful resource to students, researchers, and professionals working in solid waste management, energy and water sustainability issues within the geoscience, engineering, and chemistry fields.
This document is a compendium of scientifically valid and accepted methods that can be used to assess sediment quality and predict ecological impacts...the intent here is to provide the most useful overall measures or predictors of ecological impacts currently in use rather than procedures that may have limited application outside of a particular regulatory framework... parag The information provided in the compendium on the relative strengths and weaknesses of the different assessment methods can provide assistance in selecting the appropriate methods.
This document is intended to serve as a consistent "roadmap" for U.S. Army Corps of Engineers and U.S. Environmental Protection Agency personnel in evaluating the environmental acceptability of dredged amterial management alternatives. Specifically, its major objectives are to provide: A general technical framwork for evaluating the environmental acceptability of dredged material management, alternatives (open-water disposal, confined (diked) disposal, and beneficial uses). Additional technical guidance to augment present implementation and testing manuals for addressing the environmental acceptability of available management options for the discharge of dredged material in both ope water and confined sites. Enhanced consistency and coordination in USAC/EPA decision making in accordance with Federal environmantl statutes regulating dredged material management.
