Industrial emissions to water decreased in Europe but current levels are still a challenge for European waters

News 20 Mar 2019

Direct emissions released to water bodies from Europe’s large industrial sites have decreased in recent years for many pollutants. However, industrial pollution transferred through the sewer systems to urban waste water treatment plants (UWWTPs) has slightly increased, putting pressure on the waste water treatment infrastructure. While EU legislation tracks emissions from large industries, the extent of emissions from many small facilities remain largely unknown at European level. These are the key findings of a new European Environment Agency (EEA) analysis on data reported to the European Pollutant Release and Transfer Register (E-PRTR) and under EU legislation on water.

More action needed to tackle mixtures of chemicals in Europe's waters

News 16 Jan 2019

Despite successes in addressing some of the most hazardous chemicals, more attention is needed to address the danger posed by the 'cocktail effect' of lower concentrations of chemicals in European lakes, rivers and other surface water bodies, according to a European Environment Agency (EEA) report released today.

Restoring floodplains would improve state of water, ecosystems and climate protection in Europe

News 19 Nov 2018

Areas next to rivers hold potential for cost-effective flood protection and improving the health of an entire river ecosystem. According to a European Environment Agency (EEA) briefing published today, restoring European floodplains closer to their natural state would contribute to the achievement of several European Union policies. Estimates suggest that 70-90 % of Europe’s floodplain area is ecologically degraded.

Mercury: a persistent threat to the environment and people's health

Article 17 Sep 2018

Many people still associate mercury with thermometers and most also know that it is toxic. Because of its toxicity, mercury is on its way out from products in Europe but a lot of it is still circulating in air, water, soil and ecosystems. Is mercury still a problem and what is being done about it? We interviewed Ian Marnane, EEA expert on sustainable resource use and industry.

Climate change and water — Warmer oceans, flooding and droughts

Article 30 Aug 2018

Climate change is increasing the pressure on water bodies. From floods and droughts to ocean acidification and rising sea levels, the impacts of climate change on water are expected to intensify in the years ahead. These changes are prompting action across Europe. Cities and regions are already adapting, using more sustainable, nature-based solutions to lessen the impact of floods and using water in smarter, more sustainable ways to enable us to live with droughts.

Interview — The Dutch make room for the river

Article 30 Aug 2018

Nature and water go hand in hand. This is the thinking behind the Dutch Room for the River programme. This back-to-basics approach now serves as a global model in terms of water management and protection against increased risks of flooding linked to climate change. The most recent extreme floods in 1993 and 1995 served as a wake-up call, according to Willem Jan Goossen from the Dutch Ministry of Infrastructure and Water Management. We asked him what the programme represents in terms of sustainable flood protection.

Close up — Water in the city

Article 30 Aug 2018

We often take a reliable supply of clean water for granted. We turn on the tap and clean water comes out, we use it and the ‘dirty’ water goes down the drain. For a large majority of Europeans, the water we use at home is of drinking quality and available 24 hours a day. The brief moment between the tap and the drain is only a very small part of its overall journey. Managing water in a city is not limited to public water systems. Climate change, urban sprawl and alterations to river basins can all lead to more frequent and damaging floods in cities, leaving authorities faced with an ever-growing challenge.

Industrial waste water treatment pressures on environment

Publication 20 Mar 2019

This report analyses recent data about emissions from industry directly to water bodies as well as to sewage systems and onward to UWWTPs. The analysis focuses on the latest information for 2016, when around 3 600 industrial facilities reported at least one direct or indirect pollutant release to water to the E-PRTR database.

Mapping Europe's ecosystems

Publication 27 Feb 2019

The EU Biodiversity Strategy to 2020 calls on Member States to carry out a mapping and assessment of ecosystems and their services (MAES, Maes et al., 2013). As such, an EU-wide ecosystem assessment was launched to provide harmonised information on the condition of ecosystems and biodiversity, and their capacity to provide ecosystem services. The assessment will provide data for the final evaluation of the EU biodiversity strategy in 2020. This briefing presents recent progress in mapping broad ecosystem types and their associated habitats at European level.

Chemicals in European waters

Publication 16 Jan 2019

This report’s aim is to improve understanding of which chemicals continue to pose significant risks to the environment, especially when they are present in water. It also looks at how better knowledge and understanding can help to improve controls to minimise harm. The report gives an overview of information about pollutants used in the assessment of water quality under the Water Framework Directive, and describes some of the newer techniques available for the assessment of water quality.

Why should we care about floodplains?

Publication 19 Nov 2018

Rivers are much wider than the channels we associate them with. The areas next to rivers, which are only covered by water during floods, are also part of the river system. Known as floodplains, in their natural condition they are an important ecological part of this system: they filter and store water, secure both natural flood protection and the healthy functioning of river ecosystems, and help sustain the high biological diversity present there.

Metal pollution in the Weser catchment from mining areas in the Harz Mountains

Figure 01 Mar 2019

Water bodies have been classified under the Water Framework Directive. Blue areas are water bodies at good chemical status. Red streams are failing to achieve good chemical status. Grey areas are not classified for chemical status. The river and floodplain sediments have been contaminated with the waste and mine water over centuries. In the floodplains high lead and cadmium concentrations affect the agriculture at pasture and arable land along the river floodplains.

Chemical risk estimates for European water bodies

Use of freshwater resources

Indicator Assessment 10 Oct 2018

Despite an estimated decrease of total water abstraction by 19 % since 1990 in Europe, the milestone set in the EU resource efficiency roadmap — i.e. a water abstraction should stay below 20 % of available renewable water resources in Europe — has not been achieved in 36 river basins corresponding to 19 % of Europe’s territory in summer 2015. Around 30 % of the total European population was exposed to water scarcity conditions in summer 2015 compared to 20% in 2014, mainly living in densely populated European cities, agriculture-dominated areas of southern Europe and small Mediterranean islands. From 2000 to 2015, in the EU-28, there was an absolute decoupling of water abstraction (-9 %) and the gross value added generated from all economic sectors (+53 %). A rapid increase (+11%) has been observed in bottled water consumption from 2010, particularly in southern and western Europe.

Water exploitation index plus (WEI+) for river basin districts (1990-2015)

GIS Map Application 10 Oct 2018

This interactive map gives a European overview of water stress conditions. The information presented may deviate from that available in the EEA member countries and cooperating countries, particularly for those countries where data availability is insufficient in the WISE SoE – Water quantity database (WISE 3). Data on hydro-climatic variables was aggregated from a daily to a monthly scale. Water abstraction data was taken from WISE 3 (annual resolution at the national scale), although there are large gaps in the time series. Therefore, intensive gap filling was performed on water abstraction data and proxies were used to disaggregate the data from the national to the sub-basin scale. Information on water use was mainly modelled on the UWWTP capacities, the E-PRTR database and the Eurostat Population change dataset (online data code [demo_gind]) among others. See the methodology chapter for further explanation of gap filling, and spatial and temporal disaggregation, and the data uncertainties chapter for current data availability. This interactive map allows users to explore changes over time in water abstraction by source, water use by sector and water stress level at sub-basin or river basin scale. The WEI+ has been estimated as the quarterly average per river basin district, for the years 1990-2015, as defined in the European catchments and rivers network system (ECRINS). The ECRINS delineation of river basin districts differs slightly from that defined by Member States under the Water Framework Directive. The Ecrins delineation is used instead of WFD because it contains geo-spatial information on Europe’s hydrographical systems with full topological information enabling flow estimation between upstream and downstream basins, as well as integration of economic data collected at NUTS or country level. In addition to using e WISE SoE – Water quantity database, a comprehensive manual data collection was performed by accessing all open sources (Eurostat, OECD, FAO) including national statistical offices of the countries. This was done because of the temporal and spatial gaps in the data on water abstraction. Moreover, a large part of the stream flow data from LISFLOOD has also been substantially updated by the Directorate-General Joint Research Centre. Similarly, a comprehensive update with climatic parameters has been performed by the EEA based on the E-OBS dataset. Therefore, the time series of the WEI+ presented in the current version might be slightly different for some basins compared with the previous version.

WISE WFD reference spatial data sets

Data 02 Oct 2018

The Water Framework Directive (WFD) reference spatial data sets include information about European river basin districts, river basin district sub-units, surface water bodies, groundwater bodies and monitoring sites used in the first and second River Basin Management Plans (RBMP). The data sets are part of the Water Information System for Europe (WISE), and compile information reported by the EU Member States and Norway to the European Commission (EC) and the European Environment Agency (EEA) since 2010.

Aquaculture production

Indicator Assessment 07 Jun 2018

Marine aquaculture production is increasing in Europe (EEA39) since the early 1990s , mostly due to salmon production in Norway which is the main producer. For the same period of time, inland aquaculture in Europe is stable, and the main producer is Turkey, indicating that much of Europe's aquaculture production takes place outside the EU28 (Figure 3). In 2015, the most cultivated species in Europe (EEA39) was Atlantic salmon, while in the EU28 blue mussels were dominant. Other important species include rainbow trout, European sea bass, gilthead sea bream, oysters and carps, barbels and other cyprinids. The countries that contribute the most to European production (EEA39) are Norway (approximately 46 % of total European production), followed by Spain, Turkey, the United Kingdom, France, Italy and Greece (Figure 6). These seven countries account for 90 % of all aquaculture production in Europe. Norway’s production is nearly all due to the farming of Atlantic salmon. Turkish production consists mainly of trout (inland), sea bream and sea bass (marine).

State of bathing waters

GIS Map Application 23 May 2018

Bathing water monitoring by country. Please note: for the scales 1:5.000.001 and less detailed, data are aggregated by country. In such case, stacked bars show percentage of bathing water quality for coastal and inland waters together. Number of bathing waters within certain category is seen in pop up window which can be turned on with a click on one of the countries. For the scale range 1:5 000.000 to 1:700,001, individual bathing water sites (points) are visible instead of classified stacked charts and are coloured according to the classification of bathing water quality. Symbol size depends on the map scale (in more detailed map scales symbols are bigger). For the scales 1:700,000 and more detailed, symbol of bather in a square appears instead of points. Symbol size depends on the map scale.
