Mine drainage and remediation techniques

In the mesotrophic Lake of Lucerne (Bay of Horw) and in the eutrophic Lake of Alpnach concentration and sedimentation of iron, copper, zinc, cadmium and lead were investigated as a function of time and depth, and compared with a series of physical and chemical parameters. A metal balance was made for the Lake of Alpnach. A model for the distribution of the metals between biomass, allochthonous material and dissolved phase was employed. Phenomenology and model lead to the following conclusions: the sedimentation of the metals is dominated by allochthonous particles, the biogenic particularization is partially reversed by lake internal decomposition processes and the trace metals reaching the sediment are partially redissolved.
