Methodology:
The data series are calculated as the average of annual mean concentrations for specific water bodies in Europe. Only complete time series after inter/extrapolation are included (see indicator's "Methodology" section).
Units:
Upper chart:
Groundwater - mg NO₃/l; Rivers - mg NO₃-N/l
Lower chart:
Lakes (mg P/l) and Rivers (mg PO4-P/l)

Figure type:
The geographical coverage is the 38 EEA member countries plus the United Kingdom, but only complete time series are included in the analysis.
Two time series are shown – a longer time series representing fewer water bodies and a shorter time series representing more water bodies.
