Book excerpt: This research program was initiated with the overall objective of evaluating the usefulness of dredged sediments as landfill material. The study is limited to the deposition of polluted fresh water dredgings from the Great Lakes area, and the major effort was centered around four disposal sites in the harbor serving Toledo, Ohio. A comprehensive sampling and testing program was undertaken in the field and in the laboratory to determine the engineering characteristics of hydraulically placed maintenance dredgings and the water quality effects associated with a typical dredging and disposal operation. Several thousand chemical analyses were conducted to assess the pollution potential of dredged materials under chemically treated and nontreated conditions. Several series of flocculation-sedimentation, sedimentation-leaching, repeated leaching, and evaporation tests were conducted to study the possibility of stabilizing these materials with chemical additives and to evaluate the effects, if any, of such chemicals on the leachates. Numerous index property tests were performed for classificatory purposees, and several correlations among different properties and the results of the index tests were established. An extensive field monitoring program was undertaken to evaluate the effects of a typical dredging and disposal operation on the water quality parameters of the environs. Periodic vane shear tests were conducted in two of the areas, and settlement plates were installed at one site to determine the time-dependent variations in the strength and settlement, respectively. Several in situ permeability tests were conducted on the foundation soils and the dredged materials to evaluate drainage conditions. Finally, a one-dimensional mathemathical model was developed to assess the relative importance of gravity drainage and evapotransporation on the desiccation and consolidation of a landfill composed of maintenance dredgings.

Book excerpt: The report presents an assessment of the dredge spoil disposal problem and outlines a research program designed to provide needed information concerning current and potential spoil disposal practices. The report format is intended to reflect the two basic objectives of the report. Section A is directed toward management level review and presents (a) pertinent background information concerning the dredge spoil disposal problem and the current study, (b) conclusions and recommendations resulting from the problem assessment phase of the study, and (c) an outline of the recommended research program. Section B provides an objective assessment of the nationwide problem in sufficient detail to permit meaningful technical review by other interested personnel within and outside the Corps. Section C has been included to show a total-problem organizational structure which is being used to guide the development of the detailed research plan.

This book was released on 2007-09-22 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: President Carter's 1980 declaration of a state of emergency at Love Canal, New York, recognized that residents' health had been affected by nearby chemical waste sites. The Resource Conservation and Recovery Act, enacted in 1976, ushered in a new era of waste management disposal designed to protect the public from harm. It required that modern waste containment systems use "engineered" barriers designed to isolate hazardous and toxic wastes and prevent them from seeping into the environment. These containment systems are now employed at thousands of waste sites around the United States, and their effectiveness must be continually monitored. Assessment of the Performance of Engineered Waste Containment Barriers assesses the performance of waste containment barriers to date. Existing data suggest that waste containment systems with liners and covers, when constructed and maintained in accordance with current regulations, are performing well thus far. However, they have not been in existence long enough to assess long-term (postclosure) performance, which may extend for hundreds of years. The book makes recommendations on how to improve future assessments and increase confidence in predictions of barrier system performance which will be of interest to policy makers, environmental interest groups, industrial waste producers, and industrial waste management industry.

Download or read book Sediment Dredging at Superfund Megasites written by National Research Council and published by National Academies Press. This book was released on 2007-10-30 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the nation's estuaries, lakes and other water bodies contain contaminated sediments that can adversely affect fish and wildlife and may then find their way into people's diets. Dredging is one of the few options available for attempting to clean up contaminated sediments, but it can uncover and re-suspend buried contaminants, creating additional exposures for wildlife and people. At the request of Congress, EPA asked the National Research Council (NRC) to evaluate dredging as a cleanup technique. The book finds that, based on a review of available evidence, dredging's ability to decrease environmental and health risks is still an open question. Analysis of pre-dredging and post-dredging at about 20 sites found a wide range of outcomes in terms of surface sediment concentrations of contaminants: some sites showed increases, some no change, and some decreases in concentrations. Evaluating the potential long-term benefits of dredging will require that the U.S. Environmental Protection Agency step up monitoring activities before, during and after individual cleanups to determine whether it is working there and what combinations of techniques are most effective.
