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.

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.

This century has seen the costliest hurricanes in U.S. history—but who bears the brunt of these monster storms? Consider this: Five of the most expensive hurricanes in history have made landfall since 2005: Katrina ($160 billion), Ike ($40 billion), Sandy ($72 billion), Harvey ($125 billion), and Maria ($90 billion). With more property than ever in harm’s way, and the planet and oceans warming dangerously, it won’t be long before we see a $250 billion hurricane. Why? Because Americans have built $3 trillion worth of property in some of the riskiest places on earth: barrier islands and coastal floodplains. And they have been encouraged to do so by what Gilbert M. Gaul reveals in The Geography of Risk to be a confounding array of federal subsidies, tax breaks, low-interest loans, grants, and government flood insurance that shift the risk of life at the beach from private investors to public taxpayers, radically distorting common notions of risk. These federal incentives, Gaul argues, have resulted in one of the worst planning failures in American history, and the costs to taxpayers are reaching unsustainable levels. We have become responsible for a shocking array of coastal amenities: new roads, bridges, buildings, streetlights, tennis courts, marinas, gazebos, and even spoiled food after hurricanes. The Geography of Risk will forever change the way you think about the coasts, from the clash between economic interests and nature, to the heated politics of regulators and developers.
