Activities and Progress

During the wetland efficiency study carried out within the Min-North project metal and nitrogen retention processes in treatment wetlands are being evaluated via field (mining site north of Finland) monitoring activities (measurements of ground frost, snow cover, gases emissions and soil pore and discharge water sampling) and pilot experiments (flow through undisturbed soil samples). The work is being conducted in two concurrent phases; in phase 1 the assessment of influence of low temperatures and freeze-thaw cycles in the wetland purification efficiency in field conditions is being accessed (monitoring started in January 2016); while in phase 2 the assessment will be done via pilot scale wetland experiments (May-December 2017).

Preliminary results of the field monitoring phase will be presented (poster) during the 13th International Mine Water Association Congress, Lappeenranta, Finland (June, 2017). Full manuscript including both pilots to be submitted at the end of 2017.

Results will also be presented during the joint Min-North and RESEM project seminar to occur towards the end of September 2017. Further details will be posted soon!
