In 2025, 85% of the EU's 22,000 bathing water sites were classified as excellent quality, and 96% met at least the minimum requirements of the Bathing Water Directive (BWD), according to a briefing published by the European Environment Agency (EEA) on 16 June 2026. However, 1.5% of sites remained of poor quality, indicating insufficient or ineffective management measures. The briefing, based on data from EU Member States, Albania and Switzerland for the 2022-2025 bathing seasons, also highlights that coastal waters (88% excellent) outperform inland waters (78% excellent), with river sites particularly challenging — only 47% of around 1,200 designated river bathing sites achieved excellent quality.
The EEA briefing marks 20 years since the adoption of the revised BWD in 2006, which shifted from simple compliance to a science-based approach focused on active water quality management, public health protection and transparent information. The improvement in bathing water quality over recent decades is largely attributed to reduced discharges of untreated or partially treated urban wastewater, driven by systematic monitoring under the BWD, investment in wastewater treatment plants, and better collection networks. The briefing notes that bathing is now possible in many formerly heavily polluted urban waters and rivers, illustrating the tangible benefits of well-implemented policies.
The BWD specifically monitors faecal indicator bacteria (Escherichia coli and intestinal enterococci) to protect bathers' health, but does not cover chemical pollutants such as nutrients, pharmaceuticals and pesticides, which are addressed under the Water Framework Directive (WFD). The EEA briefing places these findings in the context of the EU's zero pollution action plan and a broader legislative framework, including the Urban Waste Water Treatment Directive, the Nitrates Directive, and the Marine Strategy Framework Directive. It also references the European Commission's water resilience strategy adopted in June 2025, which aims to restore the water cycle and enhance water efficiency, and updated EU rules on water pollutants adopted in May 2026, introducing stricter standards for emerging contaminants like PFAS and microplastics.
Stakeholder impact and trade-offs
EU consumers and bathers benefit directly from high-quality bathing waters, with 96% of sites meeting minimum safety standards, reducing health risks from faecal contamination. However, the 1.5% of poor-quality sites and the low share of excellent river sites (47%) mean that bathers in certain areas, particularly on inland rivers, face higher health risks and may need to rely on local warnings.
National authorities in EU Member States bear the cost of monitoring and managing bathing waters, including sampling, analysis, and implementing pollution control measures. Countries with lower excellent ratings (e.g., Belgium, Hungary, Poland, Estonia) may face pressure to invest more in wastewater treatment and catchment management to meet BWD standards.
EU regulatory bodies, such as the EEA and the European Commission, use the data to assess policy effectiveness and drive further legislative action. The briefing supports the zero pollution agenda but also highlights a trade-off: the BWD's narrow focus on faecal indicators does not capture chemical pollutants, meaning that even 'excellent' bathing water may not meet WFD chemical standards. This creates a regulatory gap that the updated water pollutants directive (May 2026) aims to address, but also imposes additional monitoring and compliance costs on industry and water utilities.
Industry sectors, particularly tourism and recreation, benefit from high bathing water quality, which attracts visitors to coastal and lake destinations. Conversely, poor water quality can deter tourism and harm local economies. The briefing's data on country-level performance can influence travel decisions and investment in water infrastructure.
Institutional follow-up
The EEA briefing is part of ongoing reporting under the BWD and feeds into the EU's zero pollution action plan. The European Commission is expected to continue implementing the water resilience strategy with over 50 actions, including improved enforcement of existing legislation and more integrated water management. A recent evaluation of the BWD confirmed its effectiveness but highlighted the need to modernise monitoring and improve alignment with broader EU objectives, which may lead to future legislative proposals.
