This book was released on 1996 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contaminated dredged material is sometimes placed in confined disposal facilities (CDFs) where the potential for movement of contaminants to groundwater and surrounding surface water by leaching is an important environmental concern. Column leach tests have been developed as laboratory-scale physical models of contaminant leaching in a CDF that include advective-dispersive and other mass transfer effects. Column leach tests are recommended for predicting leachate quality in CDFs containing estuarine dredged material leached by low-ionic strength water. Under the influence of decreasing ionic strength, contaminant release from estuarine dredged material is complicated by destabilization of the sediment colloidal system. These effects are better predicted with the column leach test described in this report than with the sequential batch leach test previously recommended for leach testing of freshwater sediments. This report describes procedures for conducting column leach tests and provides guidance on interpretation of results for estuarine sediments. Mathematical formulation of sorption descriptors that account for salt washout effect is also described.

This book was released on 1992 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laboratory studies of sediment leaching are being conducted at the U.S. Army Engineer Waterways Experiment Station. The purpose of these studies is to develop laboratory tests and data interpretation algorithms for predicting leachate quality in confined disposal facilities (CDFs) for dredged material. Leachate quality predictions are needed for evaluation of potential impacts of leachate seepage on foundation soils and groundwater. Two types of laboratory leach tests are under investigation, batch and column. A sequential batch leach test is being developed to provide a short-term laboratory test that describes the distribution of contaminants between aqueous and solid phases as sediment solids are exposed to increasing amounts of water. Column leach tests are being developed as laboratory-scale physical models of contaminant leaching in a CDF. Significant progress has been made in the development of the sequential batch leach test. Research has shown that sequential batch leach tests conducted at a liquids-to-solids ratio of 4 to 1 (by weight) and a shake Contaminant mobility, Dredged material, Contaminated sediment, Leach tests.

Available in PDF, EPUB and Kindle. Book excerpt: Sediment Toxicity Assessment provides the latest information regarding how to evaluate sediment contamination and its effects on aquatic ecosystems. It presents an integrated ecosystem approach by detailing effective assessment methods, considerations, and effects to each major component of marine and freshwater systems, including the benthos, plankton, and fish communities. The approaches emphasize defining habitat conditions (physical and chemical), toxicant bioavailability, factors influencing toxicity (lab and field), biomarkers, acute and chronic toxicity, study design, collection methods, and EPA management strategies. The book also explains how to integrate the assessments. Sediment Toxicity Assessment will be useful to to all environmental managers, environmental scientists, ecotoxicologists, environmental regulators, aquatic ecologists, environmental contractors and consultants, instructors, students, conservation commissions, and environmental activist organizations.

This book was released on 1995 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distinct differences in leaching characteristics of fresh-water and estuarine sediments have been observed and documented (Brannon and others 1991; Lee and others 1993a, b, c; Myers and Brannon 1993). Anaerobic leaching of fresh-water sediments with distilled-deionized (DDI) water produces aqueous leachate samples relatively free of microparticulates (Brannon, Myers, and Price 1992). Conventional liquid injection procedures (American Public Health Association 1989, U.S. Environmental Protection Agency 1986) for TOC determination are analytically sound for these leachate samples. Column leaching of estuarine sediments with DDI water initially produces microparficulate-free leachate samples. After leaching several pore volumes, leachate samples containing nonfilterable colloids and nonsettleable microparticulate matter are obtained (Lee and others 1993a, b, c). Analysis of these samples for metals and organic species using standard procedures presents no major obstacles. However, analysis of these samples for TOC using standard techniques has been subject to error due to the nonhomogeneity of the samples and the dispersion of TOC in both water and colloid phases. pg2.

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

Download or read book Sediment Quality Assessment written by Graeme Batley and published by CSIRO PUBLISHING. This book was released on 2016-02-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contaminated sediments represent an ongoing threat to the health of aquatic ecosystems. The assessment of sediment quality is, therefore, an important concern for environmental regulators. Sediment quality guidelines are now well established in regulatory frameworks worldwide; however, practical guidance that covers all of the key aspects of sediment quality assessment is not readily available. In 2005, CSIRO published its highly cited Handbook for Sediment Quality Assessment. In the ensuing period, the science has advanced considerably. This practical guide is a revised and much expanded second edition, which will be a valuable tool for environmental practitioners. Written by experts in the field, it provides coverage of: sediment sampling; sample preparation; chemical analysis; ecotoxicology; bioaccumulation; biomarkers; and ecological assessment. In addition, detailed appendices describe protocols for many of the tests to be used.
