Abstract [en]

This thesis raises the problem with acid mine drainage around the closed mine Finngruvan.The purpose of the investigation was to compare metal content in surface water in the areaand its catchments between year 2010 and 2003, also to make calculation of specific runoffand metal load, furthermore determine the recipients in the area. Surface water samplingwhere preformed at the same place as 2003 and also at a few other places of interest. Adigital elevation file were used in GIS to calculate the area of the watersheds in the region,observations in the field where also made. The collected data were used to make comparisons,calculations and conclusions. The result showed that the surface water 2010 had somewhatlower metal concentrations. The metal load calculation shows that most metals leak in thesouthern basin, but significant leakage also occurs in the western basin. The receptors in theregion are Hånsjön, Abbortjärn and Garphytteån. Conclusion to confirm the results in thisinvestigation, continuous surface water sampling is needed.
