Available in PDF, EPUB and Kindle. Book excerpt: Part of a broader investigation of soils and water contamination at the Reynolds Metals plant at Massena, New York. This phase of the overall program focus on potential PCB contamination of St. Lawrence river sediments from the plant outfalls. Objectives are: 1) Determine the verticla and horizontal distribution of PCBs in sediment adjacent of plant outfalls; 2) Characterize the chemical form of the PCBs found in the sediments; 3) Assess the relative importance of each of the four outfalls as past or present PCB sources; 4) Assess the potential for PCB contamination of this section of the river from upstream and downstream sources other than the Reynolds plant; 5) Characterize the important modes for PCB dispersion within the river sediments adjacent to plant.

This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This document is intended to help proponents & managers of dredging & marine engineering projects to design & implement sediment sampling plans that satisfy concerns about the physical & chemical characterization of sediments. The introduction describes the relevance of this guide & the context in which it was written. Chapter 2 introduces the principal objective of sediment characterization studies and discusses factors that may affect the informational value of the samples. The third chapter covers the planning of sampling operations, including development of a specific sampling approach, and explains the main components of a study design. The last chapter describes how to develop a quality assurance & control program. Appendices include statistical formulas for calculating sample size, a table showing numbers of samples required for dredging projects of different sizes, and an alternative approach for evaluating environmental sampling effort based on the use of Bayesian mathematics.

Download or read book Manual of Aquatic Sediment Sampling written by Alena Mudroch and published by CRC Press. This book was released on 1995-02-15 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little attention has been paid to the techniques for aquatic sediment sampling in the scientific literature dealing with environmental issues. With increasing interest in aquatic sediments as a sink source of contaminants in aquatic ecosystems, it has been recognized that sediment sampling is a complex and poorly documented discipline. No standardized methods exist to preserve the integrity of sediment and, particularly, sediment pore water, during sampling for different analyses and biological testing for assessment of sediment quality. A practical guide presenting the various methods available would prove extremely valuable. This is that guide. The book begins with a description of the objectives of sediment sampling for different purposes and planning of sampling programs. Most commonly used and readily available samplers and sampling techniques are explained for routine monitoring of sediment contamination and studies of sediment quality. Sample handling, transport, and storage are outlined relevant to the subsequent use of the collected sediments in physico-chemical analysis and biological testing. Measurements and notes of observations in the field during collection of sediments are described. Methods and equipment for collection of sediment pore water are detailed, and the efficiency, cost, and safety involved in sediment sampling are considered. The Manual of Aquatic Sediment Sampling contains examples, figures, and tables to enhance the reader's understanding of the material and of the importance of choosing proper techniques in sediment sampling programs. For each topic, recent citations are included from specialized literature. The Manual of Aquatic Sediment Sampling contains many examples, figures, and tables which will help the reader to understand the importance of choosing proper techniques in sediment sampling programs, and will provide a guide to preparation and execution of such programs.

Available in PDF, EPUB and Kindle. Book excerpt: "Bottom and suspended sediment was collected from the St. Lawrence River between Kingston and Cornwall inJuly 1981 by the Water Quality Branch, Ontario Region. Samples were analyzed for organochlorine pesticides, PCBs, chlorobenzenes and organic carbon. Particle size distribution was determined on bottom sediment. This report summarizes the concentration and distribution of the trace organic contaminants and compares findings with other available historical data. Total PCBs were compared with the Ontario Ministry of Environment dredged material guideline for open water disposal"--Abstract, p. v

This book was released on 2012 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The St. Lawrence River is subject to various anthropological pressures that can entail negative consequences for the ecosystem. As a result of the third and fourth St. Lawrence Action Plans, the current vision of sustainable management of this river and its main functions emphasizes the need for sound risk-based assessment approaches to support management decisions. More specifically, the sustainable navigation strategy, drawn up under St. Lawrence Action Plan III, explicitly identifies the need to develop sediment quality assessment tools, including those derived from ecotoxicological studies. The first management option addressed in this perspective was the open-water disposal of dredged sediments. In this context, an ecotoxico-logical risk assessment (ERA) approach using chemical characterization in Tier 1 and benthic organisms' toxicity tests in Tier 2 was elaborated based on physicochemical, toxicity testing, and benthic community structure data acquired from sediment samples collected in 59 sites along the St. Lawrence River. Hence this ERA approach will be used to determine whether the risk posed by the exposure of benthic organisms to dredged sediments at deposit sites and downstream is acceptable and compatible with open-water disposal.

This book was released on 1991 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a sampling strategy to evaluate suspended sediment and contaminant fluxes in the St. Lawrence River. To overcome the logistical problems arising from the large scale of the system, samples were collected following a Lagrangian scheme according to which cross-sections were sampled in a downstream sequence, with the sampling interval approximating the time of travel between stations. The large width of the river, and imcomplete mixing of water from various sources, prevented estimating fluxes from single midstream samples. Samples were therefore taken at multiple verticals within a cross-section and analyzed separately. Preliminary analyses of the data show that the suspended sediment dynamics greatly affect contaminant fluxes in the St. Lawrence River. The study of the cross-sectional variability of sediment concentrations contributes much to understanding of dynamics of both suspended sediments and associated contaminants in large scale-rivers.
