Sickingmühlenbach

The Sickingmühlenbach is a ( with Silvertbach ) 13.8 km long, orographic left tributary of the lip in North Rhine -Westphalia, Germany.

Course

The Sickingmühlenbach formed by the confluence of Silvertbach and Loemühlenbach in Marler Sickingmühle district, near the factory premises of the chemical park and the Auguste Victoria mine. Thereafter, the stream flows in a north- northwest direction over about three miles of the landfill, a refuse heap, some settlements, a harbor area and forest along. Shortly before its confluence with the lip he crosses the Wesel- dates channel by means of a culvert.

In the lower course of the Sickingmühlenbach is straightened, diked and lined with concrete slabs. Two large rainwater retention and flood basins are located in the forest area, in the meantime, there are always paragraphs and crashes, to generate pent sections.

Pumping station

The free drainage ditch in the lip is no longer possible due to subsidence. The creek pumping station lifts the Sickingmühlenbach by approximately eleven meters. It has all 26 of Bach pumping stations of the lip Association with its 20 cubic meters per second, the largest capacity on.

Until the reorganization of the group water pipelines late 2006, the mine waste water still ran in both the Silvert as well as in the Sickingmühlenbach one.

Radionuclide

By radioactively contaminated mine water from the coal mine Auguste Victoria, the sediments of the creek are radioactively contaminated. Published in 2001 dissertation found elevated levels of the radionuclide radium - 226 that reach a maximum of 15,000 becquerels per kilogram. The dose rate on the sediments reached a maximum of 6000 nSv / h (nano Sievert per hour). Even in the mouth region of the stream levels were observed from 1700 nSv / h; in the Erzgebirge had to land because of a similar high load (1730 nSv / h) be rehabilitated. Directly below the mouth of the Sickingmühlenbachs the 226- radium concentration of the lip increased by 15-fold; to the mouth of the Rhine, the dose rates along the banks remained significantly increased.
