This table includes additional information to the above visualized indicators, i.e. a short definition of this indicator and a description of the politically determined target values as well as explaining the political intention behind selecting this indicator.
The indicator specifies the share of monitoring points at which the water-body typical benchmark values of good ecological status regarding phosphorus in flowing waters are not exceeded.
|Target and intention
Roughly half of the phosphorous entering flowing waters in Germany today originates from agriculture, and the other half comes from cities (municipal water treatment plants and rainwater run-offs). In addition to nitrate pollution, it is one of the causes of an oversupply of nutrients in rivers, lakes and seas (eutrophication). The consequences of this are algae growth, oxygen depletion all the way to fish kills or the growth of poisonous blue-green algae. For this reason, meeting benchmark values for specific types of water bodies, as specified in the Ordinance on the Protection of Surface Waters, at all monitoring points has been defined as a goal for 2030.
The data published in the indicator report 2022 is as of 31 October 2022. The data shown on this platform is updated regularly, so that more current data may be available online than published in the indicator report 2022.
