Comments: Map shows monitoring water locations and quality of bathing water from 2003 till 2013. For the scale 1:5.000.001 and less detailed, data are aggregated by country. In such case, stacked bars show percentage of bathing water quality for coastal and inland waters together. Number of bathing waters within certain category is seen in pop up window which can be turned on with a click on one of the countries. For the scale range 1:5 000.000 to 1:700,001, individual bathing water sites (points) are visible instead of classified stacked charts and are coloured according to the classification of bathing water quality. Symbol size depends on the map scale (in more detailed map scales symbols are bigger). For the scales 1:700,000 and more detailed, symbol of bather in a square appears instead of points. All symbols (charts, circles and squares with bather) are coloured according to achieved quality status. Historical data is seen in pop-up windows which can be opened with a click on individual bathing water monitoring site.
Assessment is done according to assessment rules of the Directive 76/160/EEC (classification into categories CG, CI, NC...) and of the Directive 2006/7/EC (classification into categories Excellent, Good, Sufficient...).
The EEA has checked all bathing waters for a pre-season sample and monthly samples thereafter for the 2013 season. When these requirements are met, the bathing water is categorised as 'frequency of sampling
satisfied'. If these criteria are not met, the bathing water is categorised as 'frequency of sampling not satisfied'. Bathing waters are classified as 'excellent', 'good', 'sufficient' or 'poor' if they have at least 4 (if the bathing season is less than 8 weeks long, then 3) samples distributed throughout the 2013 season, and 16
(if the bathing season is less than 8 weeks long, then 12) samples available for the assessment period.
Some bathing waters cannot be classified according to their quality. They are instead classified as 'closed' (temporarily or throughout the bathing season), 'new' (quality classification not yet possible), 'changes'
(quality classification not yet possible after changes that affect or could have affected bathing water quality) or they do not have enough samples in the 2013 season or throughout the assessment period.
