Central Baltic Project Database - Waste and pollution

Testing new storm water treatment solutions for reduction of hazardous substances and toxins inflows into the Baltic Sea

As the main result, the pollution to the Baltic Sea from the stormwater systems has been reduced in four pilot sub catchments - Viimsi (EE), Riga (LV), Turku (FI) and Lieto (FI) by applying new solutions in integrated cleaning of stormwater, management quality and real-time monitoring of water quality parameters. All pilots remain in active use of the participating municipalities.

Additionally, the project demonstrated a fruitful way of cooperating between local governments and higher education institutions in innovation for improvement of the environmental condition of the Baltic Sea. The project offered an excellent opportunity to bring together the best specialists from the participating countries for joint implementation. The project results provided to develop guidelines for constructing the wetlands and establish permanent sampling/ online monitoring systems.

Heawater improved water quality in selected small urban rivers

kersti — Fri, 07 May 2021 12:28:08 +0000

The project Heawater improved water quality in selected small urban rivers by preventing nutrients and hazardous substances inflow from watersheds to Baltic Sea.

Partners from Estonia, Sweden and Finland developed and tested new technological solutions that were specially designed for small rivers to reduce pollution load. The most suitable solution for each selected small river was tested as part of the pilot investments that were carried out in Tallinn, Söderhamn and Turku. Monitoring data shows reduction in concentration of selected indicators more than 10%.

Another project aim was to raise awareness about the benefits of restoration measures of small urban rivers both for the general public and decision-makers.

The project identified best measures for different stormwater management goals and compiled the information in a tool that support planners, decision makers and private actors looking for the best urban river restoration methods. The decision support tool provides a database with the most common and well-established solutions for urban runoff and river management. The solutions are applicable also in other regions in the Baltic Sea area.

Furthermore, the project conducted a survey in the project three cities to assess the awareness level related to water quality issues and citizens’ willingness to pay for better water quality. Although city streams are often close to people, they can nevertheless receive very little attention. Based on the answers, large proportion of respondents showed interest in managing the urban waters, and a significant proportion of respondents was also willing to participate in improving the situation. The cost benefit analysis published in the summary report demonstrates that overall benefits of improving the state of small waters and sustainable stormwater management would outweigh the costs, at least over a period of several years.

BLASTIC – Less marine litter through mapping and monitoring

Ari Brozinski — Fri, 17 Jan 2020 09:01:07 +0000

BLASTIC developed new methodology and approaches to map sources, impacts and pathways of marine litter. Mapping approaches were combined with monitoring methods to produce the ‘BLASTIC riverine plastic litter monitoring method’ guidelines.

Additionally, BLASTIC also produced a list that identifies and prioritises measures to reduce litter streams from land to sea. The list helps municipalities to create local marine litter action plans. The guidelines and the list are accompanied by a socioeconomic report that looks at the impact of marine litter.

The project tested its methodology in pilot areas, where concrete plastic marine litter was removed. The pilot along with the created materials served the general aim to increase knowledge and awareness about plastic, micro plastics and hazardous substances among different target groups. As part of this, a knowledge bank (https://www.blastic.eu/knowledge-bank/) was setup.
