It is a strip mining pit that has not been sealed and that is presumably in contact with the groundwater. This pit serves literally as the sedimentation basin for untreated water from pulp and viscose production in Wolfen before it flows into the Spittel and subsequently the Mulde. Since chlorine bleaching is used in Wolfen, it seemed reasonable to assume that deposits in the sludge of the pit included dioxins and other chlorinated hydrocarbons. Therefore, Greenpeace took a sludge sample and had it analysed: At 25 to 70 nanograms of dioxin (expressed as the toxicity equivalent, TE) per kilogram dry substance, the sludge does contain increased amounts of dioxin but not of the order that would alone require an immediate cleanup. The same is true for the chlorobenzenes and chlorophenols. Nevertheless, these loads must certainly be taken seriously. The heavy metal content (zinc, lead, arsenic, cadmium, chromium, copper, nickel and mercury) of the "Silver Lake", however, currently calls to mindthat of a coal mine and should be immediately eliminated.
