From the 2013 bathing season, the classification calculation method is amended in application of European Directive 2006/7/EC More information From the 2013 bathing season, the classification is made on the basis of the results of analyses from the previous 4 seasons of the 2 microbiological parameters Escherichia coli and intestinal enterococci, by comparing the results with the values established under European Directive 2006/7/EC

From the 2010 bathing season, the mandatory parameters to monitor and assess the quality of bathing waters have been changed. More information By the start of 2010, the Directive 2006/7/EC lays down two mandatory parameters for analysis: intestinal enterococci and Escherichia coli. Other previous parameters issued from the Directive 76/760/EEC, such as total coliforms or chemical parameters, may possibly be taken into account but are optional.
