1 EEAs assessments of the status of Europe s waters EEA visit South Baltic Water District, Sweden 16. March 2018 Peter Kristensen European Environment Agency (EEA)

2 Status of Europe s waters Overall freshwater quality (overall status, ecological status, conservation status of freshwater habitats and species); Water pollution and quality (e.g. nutrients in groundwater, rivers and lakes; pollution sources and emissions); Water and health (Bathing water quality, drinking water quality, hazardous substances related to health) Water resources focus on water scarcity and drought (Water Exploitation Index, water abstraction by sectors, water resource accounts, water efficiency) Floods and water related disasters Climate change impacts on water and water adaptation measures Hydromorphological /structural activities (e.g. hydropower, navigation, number of barriers in rivers, straightened rivers).

9 Trends in wastewater treatment ( ) Proportion of population connected to better wastewater treatment Northern Europe: Norway, Sweden, Finland and Iceland. Central Europe: Austria, Belgium, Denmark, Netherlands, Germany, Switzerland, Luxembourg and United Kingdom. Southern Europe: Greece, Italy, Malta and Spain. Eastern Europe: Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland and Slovenia. South-eastern Europe: Bulgaria, Romania and Turkey. Source Eurostat and EEA indicator Collected without treatment Mechanical treatment Biological treatment Nutrient removal Initially, for the treatment of waste water, sewage collection systems must be installed (orange bars). Waste water can then be subject to primary treatment (yellow bars), such as settling, followed by secondary treatment (green bars) to reduce the amount of dissolved and suspended organic material. Secondary treatments include those using biological methods. More stringent tertiary treatment (dark green bars) can then be applied to remove mainly nutrients.

11 EEA State of Water assessment 2018 Why, what, for who and when 2018 is the year in which the European Commission published its report on Implementation of WFD and the review of the 2 nd River Basin Management Plans (RBMPs) and start the process of evaluating the Water Framework Directive. To accompany and inform this process, the EEA has long planned a report of State of European waters The report aims to present results on: What is the status of European waters? Which pressures is causing less than good status; What progress has been achieved in the 1 st River Basin Management cycle ( )? The target audience is EU institutions (EP, COM, JRC); countries (national, River Basin District administrations working with WFD and other water policy implementation); International River Basin and Regional Sea Conventions; water experts and scientists; and general public. WFD Article 18:The EU Commission shall publish a report on the implementation of the directive two years after the Member States have delivered the RBMPs. The report shall include a review of the status of surface water and groundwater in the Community undertaken in coordination with the European Environment Agency (EEA)

12 EEA s 2018 State of Water Assessment (report/portal) The first EEA report was published in 2012, the second is planned for June European waters status and pressures Overview of status (quantitative, chemical and ecological), pressures and impacts Change in status and pressures from 1 st to 2 nd RBMPs Relationship between pressure and status (what is causing less than good status) pressures-driving force relationship.

13 Consultation draft report 15/1-28/ Consultation of draft report 15/1-28/ comments from 30 countries/stakeholders Many good suggestions and constrive comments Checks of values Some critical comments related to interpretation of the WFD, e.g. Overall status Ecological status without monitoring of biological quality elements Use of supporting quality elements Chemical status extrapolation/observations Threshold values used for groundwater pollutants, RBSPs, nutrient standards

29 Preliminary key messages I Compared to the first RBMPs, all four statuses (ecological, chemical and quantitative status) have a higher proportion of water bodies in good status in the second RBMP period. However, there are also a higher proportion of water bodies in less than good status. Both the changes in proportion good and less than good status are due to improved knowledge of the water environment (i.e. fewer water bodies have unknown status). It is positive that the ecological status for single quality elements is markedly better than the overall ecological status, and there are improvements in some of the quality elements from the first to the second RBMP period. It is also positive that without ubiquitous substances, in particular mercury, only 3 % of surface water bodies failed to achieve good chemical status and only few priority substances are causing poor chemical status. Improvements in status for a priority substance shows that Member States are making progress in tackling sources of contamination.

30 Preliminary key messages II There was a slight improvement in groundwater chemical status and quantitative status from first to second RBMP period. The results from the second RBMPs show that European waters remain under multiple pressures from water pollution, over-abstraction and structural change from human activities. These pressures affect the good functioning of water-related ecosystems, contribute to biodiversity loss, and threaten the long-term delivery of previous ecosystem services and benefits to society and the economy. With the second RBMPs the quantity and quality of available evidence has grown significantly, providing a better understanding of the status, the pressures causing failure to achieve good status, and the needed measures.
