Sampling sites which exceed the requirement for good status for total phosphorus in rivers

A graph shows the measuring points that do not comply with the orientation values for phosphorus for the years 1982 to 2023. These are divided into quality classes depending on the level of exceedance. The proportion without exceedances has increased. The proportion of medium and severe exceedances (QC IV) has fallen sharply.
