Book Description
This project is one component of the U.S. Geological Survey's National Coastal Geology Program directed to polluted sediments. Its long-term aim is to develop a comprehensive database on estuarine contaminated sediments that provides a summary of information and a digital reference source of detailed and readily accessible data. It focuses on Chesapeake Bay because there is a wealth of data on bottom sediments and sedimentary contaminants. However, this data is fragmented, uncollated and dispersed in many papers, books, reports, files and documents, often local sources, outside the mainstream of national consideration and scientific knowledge. Without an organized body of data, resource managers and research scientists are handicapped in structuring decisions and preparing plans. They may not know what data exists, where to find it and how to obtain it. Potentially valuable data may go unused because it is overlooked, poorly documented or difficult to obtain. To address problems of contaminated sediment the U.S. Geologtcal Survey's Branch of Atlantic Marine Geology (Woods Hole) executed a cooperative agreement in May 1992 with the Virginia Institute of Marine Science. The project aims to structure a PC accessible database for incorporation into CD ROM media. It draws on existing historical data, mainly from published and unpublished "grey" literature spanning the last 55 years. This contrasts to databases of NOAA's Status and Trends Monitoring Program and EPA's Environmental Monitoring and Assessment Program (EMAP) that draw on new data from field surveys. The data sources come from diverse scientific, academic, commercial and government organizations, and from a range of fields including sedimentology, geochemistry, estuarine marine science, pollution and benthic biology. Historical data are of value for evaluating changes caused by dredging and disposal as well as storms and to assess baseline concentrations prior to contamination. Database development of this project consists of four components or tasks: 1. To organize and structure a database with a set of procedures, data dictionary and codebook, formatted for transfer to a CD ROM file, 2. A search for data sources in the literature and in files on bottom sediments and their contaminants, 3. An inventory of relevant data sources according to location, station abundance, occurrence of variables, etc. 4) Compilation of prototype digital data files from selected data sources

Book Description
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.

Book Description
Contaminated marine sediments threaten ecosystems, marine resources, and human health. They can have major economic impacts when controversies over risks and costs of sediment management interfere with needs to dredge major ports. Contaminated Sediments in Ports and Waterways examines management and technology issues and provides guidance that will help officials make timely decisions and use technologies effectively. The book includes recommendations with a view toward improving decision making, developing cost-effective technologies, and promoting the successful completion of cleanup projects. The volume assesses the state of practice and research and development status of both short-term and longer-term remediation methods. The committee provides a conceptual overview for risk-based contaminated sediment management that can be used to develop plans that address complex technological, political, and legal issues and the interests of various stakeholders. The book emphasizes the need for proper assessment of conditions at sediment sites and adequate control of contamination sources.

Book Description
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.

Book Description
The Superfund program of the US Environmental Protection Agency (EPA) was created in the 1980s to address human-health and environmental risks posed by abandoned or uncontrolled hazardous-waste sites. Identification of Superfund sites and their remediation is an expensive multistep process. As part of this process, EPA attempts to identify parties that are responsible for the contamination and thus financially responsible for remediation. Identification of potentially responsible parties is complicated because Superfund sites can have a long history of use and involve contaminants that can have many sources. Such is often the case for mining sites that involve metal contamination; metals occur naturally in the environment, they can be contaminants in the wastes generated at or released from the sites, and they can be used in consumer products, which can degrade and release the metals back to the environment. This report examines the extent to which various sources contribute to environmental lead contamination at Superfund sites that are near lead-mining areas and focuses on sources that contribute to lead contamination at sites near the Southeast Missouri Lead Mining District. It recommends potential improvements in approaches used for assessing sources of lead contamination at or near Superfund sites.

Book Description
Can Americans continue to add more seafood to their diets without fear of illness or even death? Seafood-caused health problems are not widespread, but consumers are at risk from seafood-borne microbes and toxinsâ€"with consequences that can range from mild enteritis to fatal illness. At a time when legislators and consumer groups are seeking a sound regulatory approach, Seafood Safety presents a comprehensive set of practical recommendations for ensuring the safety of the seafood supply. This volume presents the first-ever overview of the field, covering seafood consumption patterns, where and how seafood contamination occurs, and the effectiveness of regulation. A wealth of technical information is presented on the sources of contaminationâ€"microbes, natural toxins, and chemical pollutantsâ€"and their effects on human health. The volume evaluates methods used for risk assessment and inspection sampling.
