Contaminated Sediments

Review of Solutions for Protecting Aquatic Environments

image of Contaminated Sediments

The Nordic Council of Ministers have recognized the need to compile the knowledge of sediment remediation strategies and to evaluate different remediation approaches. The objective of this report is to give a status of regulatory framework and sediment management within selected Nordic countries (Norway, Sweden, Finland and Denmark). In addition, the report gives a short overview of international knowledge on remediation approaches, techniques, and materials. Governance and regulatory instruments in dealing with contaminated sediments vary between countries. Of the countries presented, only Norwegian environmental authorities have implemented a national strategy for remediation of marine contaminated sediments. A Nordic database of clean-up projects and long-term monitoring would improve the exchange of knowledge between the Nordic countries.

Introduction

Contaminated sediment has been recognized as a significant reservoir of legacy contaminants in industrial sites worldwide, potentially contributing with releases of contaminants for decades after industrial releases have been stopped and acting as a source for transfer of contaminants into aquatic food chains. The Nordic Council of Ministers have recognized the need to compile the knowledge of sediment remediation strategies and to evaluate the different approaches in relation to cost, efficiency and adverse effects on the environment. The objective of this report is to give a status of regulatory framework and sediment management within selected Nordic countries (Norway, Sweden, Finland and Denmark). In addition, the report gives a short overview of international knowledge on remediation approaches, techniques and materials.
