Value cells are coloured according to exceedance of PROREF, see legend below. If there exists an EQS for the contaminant, an exceedance of the EQS is indicated by a red rectangle enclosing the cell. In order to improve visibility of the majority of the time trends, the trend plots don’t show the entire confidence intervals (the outermost/largest confidence intervals are cropped)
