European Terrestrial Reference System 1989 World Geodetic System 1984 including re-opened bathing water if closed or permanently closed in the previous season(s) existing bathing water new bathing water bathing water has a permanent bathing prohibition or permanent advice against bathing permanently closed bathing water excellent quality Bathing water reported as temporarily closed (Closed is “YT”) and not monitored or monitored but neither of other Class values are relevant. closed good quality sufficient quality poor quality frequency criteria (first sample shortly before the start of the season, sampling intervals - one month during the bathing season) and number of samples in the assessment period not satisfied not enough samples new bathing water identified with necessary dataset not compiled yet (when the classification of bathing waters according to the Annex II of the Directive has already started) new (classification not yet possible) Bathing water with necessary dataset not available yet since the occurrence of changes that affect or likely to affect classification of bathing water (water quality is influenced). It could be closed bathing water but closure itself does not always mean changes that affect classification. changes (classification not yet possible) bathing water is not situated in a region subject to special geographic constraints bathing water is situated in a region subject to special geographic constraints bathing water is not closed bathing water is permanently closed if classified as “poor” for five consecutive years or Member State released permanent bathing prohibition or advice against bathing -if closed due to bad quality, it needs to be monitored; -if closed due to other reasons that prevent sampling (e.g. renovation, not accessible due to construction activities nearby), the monitoring is not needed. Closed bathing water that is monitored can be assessed (can get Class “1” or “2” or “3” or “4”). If closed bathing water is not monitored, Class is “11”. bathing water is temporarily closed for a part of one season or the entire season, but not permanently closed no changes changes coastal water = surface water on the landward side of a line, every point of which is at a distance of one nautical mile on the seaward side from the nearest point of the baseline from which the breadth of territorial waters is measured, extending where appropriate up to the outer limit of transitional waters lake = body of standing inland surface water river = body of inland water flowing for most part on the surface of the land but which may flow underground for part of its course transitional water = bodies of surface water in the vicinity of river mouths which are partly saline in character as a result of their proximity to coastal waters but which are substantially influenced by freshwater flows Bathing water is newly identified or changes occur that affect classification in the current season. Such bathing water is assessed if the number of samples is sufficient. current season In the preceding season bathing water was newly identified or changes affected classification. Bathing water is assessed if the number of samples is sufficient. current season and preceding bathing seasons Two years ago bathing water was newly identified or changes affected classification. Bathing water is assessed if the number of samples is sufficient. current season and two preceding bathing seasons Assessment for all bathing waters is done on the basis of 4-year data set. If not enough samples were collected during 4-year period or samples are not more or less equally distributed throughout the season, the bathing water gets status "not enough samples" (Class gets value “5”). For newly identified bathing waters or bathing waters where changes affected classification number of seasons can be lower. current season and three preceding bathing seasons
