Map shows monitoring water locations and quality of bathing water from 2007 till 2017. 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 appears instead of points. All symbols (charts, circles and squares with bather) are colored according to achieved quality status. Pop-up windows can be opened with a click on individual bathing water monitoring site. Monitoring requirements such as the taking of a pre-season sample, a minimum of four samples per season and a minimum of one sample per month must be met for all bathing waters. If these rules are satisfied, the bathing water is categorised as 'sampling frequency satisfied'. If at least one monitoring requirement is not fulfilled the bathing water is categorized as 'sampling frequency not satisfied'. In such cases, bathing water can still be quality assessed if at least four samples per season (three samples if the season does not exceed eight weeks or the region is subject to special geographical constraints) are available and are more or less equally distributed throughout the season. Assessment of bathing water quality is possible when the bathing-water sample dataset is available for four consecutive seasons. For the 2017 bathing season, all reported bathing water data have been assessed under the provisions of the Directive 2006/7/EC. Bathing waters are accordingly classified to one of the bathing-water quality classes (excellent, good, sufficient, or poor). Historical data, observed in the pop-up window includes bathing water quality data from 2007 onwards. When intestinal enterococci and Escherichia coli sample datasets for four consecutive seasons were not yet available (relevant for bathing water quality data measured and reported between 2006 and 2014), the assessment of bathing water quality was conducted by using the data from the latest year only (transitional rules). The results for both parameters were classified in the following three categories: complaint with the guide values (CG), compliant with the mandatory values (CI), and not compliant with the mandatory values (NC).
