Project Details

Description

Danish lakes and rivers have during the last decennia been hit by pollution by nutrients, and consequently their value for recreation is reduced. Drinking water production based on groundwater has in the same periode within large areas of Denmark been more difficult, partly due to production, partly because of a heavy overexploitation, which is followed by salt water problems.
The problems with the lakes and the groundwater does not have a common background, but probably a common solution can be found in certain areas.
In the project it is studied, if it is possible to improve the lake water quality by removing the sediment, which is rich in nutrients and often also in heavy metals. The sediments is removed by pumping with a high percentage of water. Artificial infiltration of the water is studied- especially the cleaning capacity of the unsaturated zone. The uptake in biomass of nutrients and heavy metals is the last research topic in this project.
