Water treatment and excavation material management

Today Dr. Willscher from the chair of groundwater and soil remediation took the group under her wing and to the lignite open-pit mining site Nochten in the northern Upper Lusatian region. Here, the participants learned how water used in the mining process is treated and what happens with the excavation material.

Restoration of open-pit mining areas

The group sallied to the Lower Lusatia-region in southern Brandenburg, more precisely to the surroundings of the town Finsterwalde. Whereas the town itself has gained national fame in the late 19th century through a folk music song, the participants were dealing rather with the culture of soils and cultivation of plants today. Starting at the open-pit mining site Welzow-Süd the group got an impression of the dimension of devastated and degraded areas after lignite surface-mining. 

Subsequently, the restoration process at different stages – starting with the first planting on dumped soil, finishing with a reforested site – was examined and discussed.
