Europe's Water Revival: Cleaning Pollution, Restoring Nature

Water pollution is a pressing issue in Europe, threatening water sources and ecosystems and jeopardizing access to clean drinking and bathing water for Europeans. The continent's water resources are under pressure from various sectors, including agriculture, industry, and tourism. To combat this, the European Union and its member states have implemented various measures and policies to improve water quality, reduce pollution, and protect aquatic ecosystems. These include the Water Framework Directive, the Bathing Water Directive, and the Marine Strategy Framework Directive. The EU has also established the European Maritime Safety Agency to address marine pollution and the European Environment Agency to support policies through knowledge products and assessments. While progress has been made, challenges remain, such as the slow pace of updates to pollution thresholds and the need to address new concerns like pharmaceutical pollution.

The EU Water Framework Directive

The WFD takes a river basin district approach, recognising that many European river basins cross administrative and territorial borders. This approach ensures that neighbouring countries cooperate in managing the rivers and other bodies of water they share. Each river basin district is required to produce a River Basin Management Plan, which outlines how the objectives for the river basin will be achieved within a specified timeframe. The directive also includes provisions for monitoring requirements, criteria for assessing water body status, and the contents of the management plans.

One of the key challenges in implementing the WFD is aligning it with other regulations and policies. For example, the directive has been criticised for not fully embracing systems-thinking, which could hinder its effectiveness in water management. Additionally, there have been delays in updating the lists of surface and groundwater pollutants, which are crucial for monitoring and assessing water quality. The European Commission has proposed amendments to the WFD to address these issues, aiming to align the directive with the 2020 European Green Deal and ensure swift integration of scientific findings.

The WFD also addresses water pollution, which is caused by various sectors such as agriculture, industry, and energy. Pesticides have been identified as a major contributor to water pollution, with a significant number of approved active pesticide substances in the EU classified as having chronic aquatic toxicity. The directive includes provisions for regulating individual pollutants and setting corresponding regulatory standards. It also establishes Environmental Quality Standards (EQS) for substances of national concern, with the aim of achieving good surface water chemical status.

Overall, the EU Water Framework Directive provides a comprehensive framework for protecting and managing water resources in Europe. It aims to ensure the long-term sustainable use of water, promote cooperation among neighbouring countries, and address the challenges posed by water pollution. While there have been some challenges and delays in its implementation, the directive remains a crucial tool in safeguarding Europe's water resources for future generations.

The Bathing Water Directive

The EU's Bathing Water Directive (2006/7/EC) was introduced to enhance public health and environmental protection. It requires member states to monitor and assess bathing water quality and provide timely information to the public. This includes information on the kind of pollution and its sources, as well as notices banning or advising against bathing. The directive applies to surface waters expected to be used for bathing and excludes swimming pools, spa pools, and confined waters used for treatment or therapeutic purposes.

During the bathing season, member states must sample bathing water and assess the concentration of specific bacteria at least once a month at each site. They also have to define the length of the bathing season and establish a monitoring calendar. Samples taken during short-term pollution or abnormal situations may be disregarded, and new samples should be taken as soon as possible after such events.

The directive sets out criteria for classifying bathing water quality as 'excellent', 'good', 'sufficient', or 'poor', based on the levels of faecal bacteria detected. Member states must take appropriate measures to improve water quality, with the ultimate goal of achieving 'excellent' or 'good' status. If water is classified as 'poor', countries should implement corrective actions, such as banning bathing and providing information to the public.

The implementation of the Bathing Water Directive is supported by other EU water legislation, including the Water Framework Directive, the Environmental Quality Standards Directive, and the Urban Waste Water Treatment Directive. These directives work together to protect and manage Europe's water resources and ensure clean drinking and bathing water for all Europeans.

The European Commission and the European Environment Agency publish annual summary reports on the quality of bathing water, tracking data from over 22,000 sites across Europe. This systematic monitoring and management, along with investments in wastewater treatment plants, have contributed to significant improvements in bathing water quality across the continent.

The Drinking Water Directive

The DWD aims to protect people and the environment from the harmful effects of contaminated drinking water and to improve access to drinking water. It introduces minimum requirements for materials that come into contact with water meant for human consumption throughout the EU. These requirements include the absence of micro-organisms and parasites dangerous to health, as well as compliance with Annex I (microbiological and chemical parameters and those relating to radioactivity). The directive also sets out a framework for minimum hygiene requirements for materials in contact with drinking water.

Articles 8 to 13 of the DWD outline the obligations of member states, including regular monitoring of the quality of water intended for human consumption using specified methods of analysis, and the publication of drinking water quality reports every three years. Member states must also report on the quality of drinking water to the European Commission and the public. The directive allows for temporary exemptions, provided that they do not affect human health.

The recast Drinking Water Directive includes additional restrictions on the presence of potentially dangerous compounds in water, such as polyfluoroalkyl substances, endocrine disruptors, EDCs, and microplastics. It also allows for derogations in justified circumstances, where member states may set less stringent values than the parametric value, as long as it does not pose a potential danger to human health.

The implementation of the DWD is essential to protect human health and ensure access to high-quality drinking water, which is crucial for public health, well-being, and various other purposes.

The Water Convention

The convention has been in place for over 30 years and has facilitated cooperation and supported policy processes and capacity building in shared basins. In 2021, the landmark decisions were made to strengthen the convention's role as a global framework for transboundary water cooperation. The Protocol on Water and Health, jointly serviced by UNECE and WHO-Europe, is a legally binding instrument that supports the goals of the Water Convention. North Macedonia and Uzbekistan recently joined this protocol, demonstrating their commitment to improving water and environmental management and ensuring access to water and sanitation for their populations.

The European Union (EU) has also taken several measures to address water pollution and protect water resources. The EU Water Framework Directive establishes a legal framework to protect and restore clean water and ensure its long-term sustainable use. The Environmental Quality Standards Directive sets environmental quality standards for priority substances and certain other pollutants, with the aim of achieving good surface water chemical status. The EU has also established the European Maritime Safety Agency to prevent and respond to pollution caused by ships and oil and gas installations.

Overall, the Water Convention and the efforts of the EU demonstrate a commitment to addressing water pollution and ensuring sustainable water use for the benefit of people and the environment.

The Zero Pollution Action Plan

Water is a fundamental resource for people and nature, and for regulating the climate. It is also crucial for the economy, agriculture, and energy production. However, water pollution poses a serious threat to water resources and aquatic ecosystems. In Europe, only 38% of surface waters are considered to have a healthy chemical status. To address this issue, the European Commission has adopted the Zero Pollution Action Plan, which aims to strengthen the EU's green, digital, and economic leadership while creating a healthier and more socially fair Europe and planet.

The European Commission's proposal adds crucial water pollutants such as PFAS, pharmaceuticals, and pesticides to the list of priority substances for surface water. Member States are responsible for monitoring the presence of these substances in water and ensuring that quality standards are met. The Water Framework Directive (WFD) establishes a legal framework to protect and restore clean water and ensure its long-term sustainable use. It aims to prevent and reduce pollution, promote sustainable water use, and protect and improve the aquatic environment.

The EU has also implemented the Bathing Water Directive, which aims to enhance public health and environmental protection by monitoring and classifying bathing water quality. During the bathing season, Member States must assess the concentration of specific bacteria at each bathing site and inform the public through "bathing water profiles." Additionally, the Environmental Quality Standards Directive sets limits on the concentration of priority substances and pollutants in surface waters to protect the aquatic environment.
