Where is the water cleanest in Denmark?
858 sites have held the top rating five seasons running — a far better signal than a single good year. Around Copenhagen, Aarhus, Aalborg you will find the densest clusters.
How often is water quality tested in Denmark?
Through the whole bathing season. National sanitary authorities sample each official site for E. coli and intestinal enterococci, report to the European Environment Agency, and the published class reflects the last four seasons combined.

Ratings are the official season-long classification, computed from the last four seasons of sampling — not a live reading. After a storm any site can be temporarily worse; local advisories win.
