Sediment Risk Management and Communication WP 5 Outcomes

Journal of Soils and Sediments, 2008

Background, aims and scope One issue that remains particularly problematic for integrated and sustainable sediment management is that sediment plays differing roles in various sectoral, regulatory and statutory objectives. This means that across Europe, the level of consideration afforded to sediment management has thus far been primarily left to the discretion of individual countries and agencies. One of the consequences of the complex way in which sediments are regulated in Europe, and a possible over-reliance on the precautionary principle, is that there appears to be less regulatory acceptance of risk-based (rather than mass-based or chemical threshold-based) sediment remedial decisions, and thus resistance to some of the risk-based and in situ remedial technologies currently favoured in North America; "presumptive remedies" are being pushed by a number of agencies, and in-place and risk-based management are meeting great resistance. This summary discusses some of the current and emerging European regulations and strategies and their implications for risk-based sediment management.

This is the second of a two-part review article on the assessment and management of contaminated sediments. Part I, "Developing an Effective Investigation and Risk Evaluation Strategy," appears in both the print and online editions of IEAM Volume (1), Number (1).

The dynamic nature of sediments, from rivers to estuaries and the sea, calls for a holistic approach to sediment management that ensures that transport, quantity and quality are explicitly addressed throughout the framework. If sediments are hydrodynamically connected, it makes sense to prioritize those that pose risk downstream, and to do this in a manner that considers the entire sediment,contaminant and risk budget, from source to sink. Such an approach will provide insight into the highest impact potential changes in agricultural, industrial and development practices that may reduce sediment and contaminant inputs, and hence the cost of maintaining waterways and protecting the environment.Conceptual frameworks for basin-scale sediment management that provide an approach for addressing the complexities inherent in managing sediments at both a basin-wide and site-specific scale and their role in holistic European basin-scale sediment management decision making, are discussed.

r eseArch from a nImAl t estIng to c lInIcAl e xperIence Summary. Sediment management nowadays is often concerned around sediments that have been polluted in former times, posing the following questions: what risks remain after time has passed concerning the persistence, ageing and bioavailability of the polluting substances; where does the risk apply regarding the transport of contaminated sediments

The US. Army Corps of Engineers has statutory authority to regulate the disposal of dredged material in waters of the United States under the Clean Water Act and in the oceans under the Marine Protection, Research, and Sanctuaries Act. In carrying out this authority, the Corps has conducted over $100 million of research on dredging and the disposal of dredged material. As required by domestic law and the International London Dumping Convention, the suitability of dredged material for open-water disposal is determined by an ecological effects based approach rather than consider ation of the concentrations of chemical contaminants in the sediment. The rationale for this is that dredged material is a complex mixture of many substances whose bioavailability and potential interactions cannot be predicted merely on the basis of the concentrations of the chemicals of concern. This effects based approach uses physical, chemical, and biological assessments, and consists of contaminant mobili...
