Bathing water quality
Bathing water is any section of surface water for which the competent authority anticipates a large number of bathers and for which it has not issued a permanent ban on bathing or does not advise against bathing on a permanent basis.
The quality of a bathing water provides information on the extent to which it is harmless to health. It is regularly monitored during the bathing season from 15 May to 15 September.
