Data: LANUV NRW

The River Lippe is a tributary of the Rhine, with rural catchment upstream of Hamm, industrial and mining catchment downstream.

EQS for mercury was not being achieved, so in 2012 additional monitoring programmes were started to better characterize discharges and status. Improved data were used in modelling, showing the pollutant pathways

·         Industrial discharger and power plants: 30 – 45%

·         Municipal sewage plants: 6 – 12 % (more than 90 plants)

·         Diffuse sources: 30 – 45%

Pollution permits were revised for power plants and the chemicals park, rain water systems improved and the chlor alkali production process [closed down]. These actions led to reduction in mercury load between 2008-14.
