With a long coastline and many lakes, Sweden has many beaches and swimming areas. Our agency oversees the regulations and guidelines related to bathing water quality in Sweden.
Information on water quality is important because some swimming areas can occasionally contain high levels of bacteria or algae which can present health hazards.
For example, water that contains intestinal bacteria can cause stomach upsets. When plankton algae multiply in very large numbers (algal blooms), they sometimes release toxins that may cause a variety of symptoms.
Sweden's local municipalities have been testing the water quality of their swimming areas for many years. The EU's Bathing Water Directive specifies how this testing should be carried out.
Our agency, in accordance with the Directive, issues detailed instructions for collecting water samples.
Our interactive map (in Swedish) shows the water quality for the swimming areas that are monitored in Sweden. Results of the most recent samplings are shown, and information is updated whenever new test results are received from municipalities.
The map also contains data on algal blooms, whether or not the site is an EU bathing site, contact information for the responsible municipality, and if there is a current warning against bathing in that area.
