In Situ Contaminated Sediment - WT1501

Defra is seeking to understand the risks that in situ contaminated sediments pose to sensitive receptors (e.g. aquatic ecology and human health) and the impacts that these risks may have on the way that water bodies are managed. The project¡¦s overall aim was therefore to provide a sound evidence base that can underpin the development of tools to help Defra, the Environment Agency and other bodies engaged in the regulation and protection of water quality make evidence-based decisions to address the risks associated with in situ contaminated sediment.
The aim of this project was to build upon the existing evidence base, drawing together information on the freshwater environment to complement that already gathered for marine waters, in order to review and assess the risk posed by contaminated sediments. Once the risk was qualitatively identified, the project proposed to then identify practical and cost effective mitigation measures that could be applied, when needed, as part of a national risk assessment and management approach. This project encompassed both freshwater and marine sediments in England and extended to one nautical mile off-shore (the marine boundary of regulation under the EU Water Framework Directive in England).
