The Röseckenbach is an approximately four-kilometer-long right tributary of the Oker , which rises south of Göttingerode in the Harz Mountains in the Hessental, crosses the Tönneckenkopf – Röseckenbach nature reserve and runs over the site of the former Oker zinc oxide smelter in the Oker district of Goslar . In front of its confluence, it picks up the water-rich turbine trench of the power plant built on the smelter site.

etymology

The name Röseckenbach is derived from Kalkröse . In the early modern period, the term Kalkröse or Kalkrose was understood to be a bulge of limestone, as existed on the Langenberg protruding north of the Röseckenbach . The ending -ecke is a locally common ending for river names in general, so unnamed streams are traditionally called Strüllecke in the Bad Harzburg region . The calcareous roses were first mentioned on Langenberg in 1457.

geography

One source of the Röseckenbach is the Heinrichbrunnen on the northern slope of the Goldberg about 1.5 km south of Göttingerode. Its course flows through the valley of the same name as the Hessentalbach , receives a tributary from the right and leaves the forest at Göttingerode. He turns to the northwest, obtained from the left a further influx in the dog Born (coordinates: 51 ° 53 '  N , 10 ° 30'  O ) from the Drecktal and flows through the also named after him protected area between the resin and the Kalkabbaugebiet of the upstream Lange Berg , where another feeder from the Quisselbeerental flows in.

Below the crossing through Kreisstraße 70 between Oker and Harlingerode , he enters the smelter site now operated by the Harz-Metall company. There it is mostly run underground and only appears again on the Oker – Bad Harzburg railway line that borders the company premises . He is the receiving water on-site wastewater treatment facility and receives only a few meters from the mouth of a significant turbine water flow from Hüttengraben .

The Hüttengraben, also known as the Marien-Saiger-Hüttengraben, branches off up the Oker at the Waldhaus at the street Am Pfennigsteich from the Oker and leads directly to the power station of the hut area.

Water quality

The water quality report of the NLWKN from 2002 refers to the natural upper course as well as to the piped and forced into concrete walls sections in the area of ​​the hut area and its drainage. The biological quality of the stream was assigned to water quality class I. The problem was and is the very high heavy metal pollution, especially zinc, lead, copper and cadmium, which results from the catchment area of ​​the brook: In the entire lower reaches of the slag heaps of the Oker lead smelter and other spoil heaps, whose surface water is absorbed by the brook after rain events becomes.

The operating company of the smelter site has set up a central wastewater treatment plant for which the NLWKN 2015 specified the permissible discharge values: In addition to the usual limit values ​​for COD and AOX , these are 150 µg / l for cadmium, 200 µg / l for lead and 300 µg / l for copper a limit value for toxicity to fish eggs. The total annual amount of dirty water was fixed at 330,000 m³ and a further 290,000 m³ for the amount of cooling water.
