Developing the monitoring of pollutans from stormwater.

The project” New methods to promote water purity – WaterPlus” aims to promote water purity” aims to develop the analysis and monitoring of pollutants, especially microplastics, from stormwater. In addition, the aim is to develop detection, sampling, and filtration methods for micro- and macroplastics carried with stormwater.


New methods to get information from surface water

The quality and management of stormwater, as well as pollutants and nutrients leaching into water system through them, have been identified as one of the sources of load on water system. From the point of view of load management, it is important to determine the pollutants contained in stormwater. To obtain the information, it is necessary to develop and test new monitoring and purification technologies.

Research data related to stormwater quality is often still scattered and doesn´t serve the needs of urban planning and water protection. Creating a common data platform will facilitate data sharing and increase cooperation between different actors. Citizens’ observations can be used to assist in observations of the state of water system, and so target research and measures in specific areas.



1)Study of status of South Savo water system for micro- and macroplastics and contaminants
2) Integrating public observations into water status monitoring
3) Piloting of monitoring methods in demonstration sites
4) Development of methods for controlling plastics
5) Development of a platform suitable for sharing environmental information for the needs of water research – Case Mikkeli
6) Communication, information, and implementation of results


Sampling and analysis methods for stormwater pollutants to be developed and tested in the project will provide efficiently more information of the status of stormwater and changes in it. In addition, the project will provide information on various methods suitable for the control and removal of microplastics from water system.

Citizens’ observations and a common data platform create the conditions for collecting even more extensive data on the status of surface waters and help to keep water system clean. The information produced by the project supports the maintenance of clean water in South Savo and prevents the risk from microplastics to environment.


In the spring of 2022, microplastic and harmful substance sampling was carried out in Etelä-Savo. A video of the sampling can be seen at:


Along with stormwater, a surprising amount of garbage is carried into natural waters!
