Management of contaminated sediment, an overview.
Over the last decades large amounts of heavy metals and hydrophobic organic chemicals like PCBs, PAHs and dioxins have accumulated in sediments.
These pollutants may cause certain risks to benthic communities and functioning of aquatic ecosystems, to human health, to groundwater quality and to surface water quality.
If contaminated sediment should be removed for environmental, nautical or hydrological reasons, the question arises how to handle the sediment.
Treatment, disposal and reuse, and combinations of these options, are considered.
It is argued that there is a need for an integrated management strategy for contaminated sediment on European, national and local levels.
Such a strategy should include monitoring, assessment, establishment of quality criteria, prevention and remediation.
