Welcome to find support for water protection!

Welcome to finding information, examples and practical tips for water protection!

Tools for water protection is a web-based toolbox providing support for implementing water protection actions at local level. It is designed for professionals and experts who do concrete work, strategic planning or make decisions on water protection in cities, municipalities, companies, NGOs or other organisations.

The Toolbox provides information and tools that assist with water protection. In addition to practical tips, tools and background information, in the Bank of Actions you can browse actions that local organisations have already implemented for the protection of local waters and the Baltic Sea – and you can also share your organisation’s own actions!

This site was established in 2015 by the EU Life+ funded project CITYWATER, in collaboration with the Baltic Sea Challenge. The first tools are based on the results of the CITYWATER project. The site is now managed and updated by the Baltic Sea Challenge. More tools and actions are needed – please contact us and tell us about your ideas!

Environmental dredging of contaminated sediments

Actor: Port of Turku   ●   Year: 2009   ●   Address: Linnankatu 90, Turku, Finland

The environmental dredging of River Aurajoki was done by the Port of Turku during October 2008 - January 2009. The total mass of sediments that was moved by stabilising to the special lagoon of Pansio was about 88 000 m3.© Port of Turku


Contaminated sediments had been found widely on the lower reaches of River Aurajoki. According to the examination tributyltin (TBT) appeared across the sediments of the seabed (0-20cm), furthermore, levels of some heavy metals were also high.


The bottom sediments of River Aurajoki’s lower reaches were cleaned. Because of this, it was possible to eliminate spreading of contaminants to the area affected by River Aurajoki discharge, straits and harbour. From the Port of Turku’s point of view, the dredging was a preventive action. In the future the solid substances discharged with the currents are cleaner than before and will not cause problems for the maintenance dredging of the port.

Background information

The action was voluntary. The port found it necessary to carry out the environmental dredging as a preventive action. The EU-Life STABLE project was also a part of the action. The project developed process handling technique of the contaminated sediments in the special lagoon of Pansio.
