INDICATOR DESCRIPTION
The indicator shows the average annual concentration of orthophosphate in the rivers. Phosphate is a key nutrient that limits the growth of algae, mosses and aquatic plants in aquatic environments and is present at very low concentrations in unpolluted rivers (the indicative value for the natural state is 0.010 mg P/l). Concentrations of orthophosphate in water that are larger than the natural background are mainly due to agriculture and the discharge of municipal and industrial sewage into the rivers. The surpluses of nutrients in rivers lead to a deterioration of the normal functioning of the ecosystem, reduced biodiversity and eutrophication, which is particularly problematic in standing or slowly running waters.

The indicator can also be used to complement the monitoring of goal 15.
