European Bathing Water Quality
Every officially designated bathing site in Europe in one clean, geolocated table: ~27,800 inland, coastal, river and transitional bathing waters across 31 countries, classified each season as excellent / good / sufficient / poor under the EU Bathing Water Directive (2006/7/EC) - one row per site x season, 1990-2025. Assembled and de-duplicated from the EEA WISE DataHub release: site id/name, country, water-body type, latitude/longitude, season year, quality classification plus monitoring and management status. Ready to map or join by site or country.
