Data centre overview

Provisional data reported in 2022. Urban Waste Water Treatment Directive concerns the collection, treatment and discharge of urban waste water and the treatment and discharge of waste water from certain industrial sectors. The objective of the Directive is to protect the environment from the adverse effects of the above mentioned waste water discharges.

The figure shows the percentage of monitoring sites with threshold exceedances of pesticides in surface waters, different sized rivers, lakes and groundwater in European countries. This was used to examine threshold exceedances according to Surface Waters; Rivers, small; Rivers, medium; Rivers, large; Lakes, and Groundwater.

The regional seas around Europe are the Baltic Sea, the Barents Sea, the Black Sea, the Iceland Sea, the Mediterranean Sea, the North-east Atlantic Ocean, the Norwegian Sea, and the White Sea. The regional seas are harmonised with existing boundaries established under the Regional Sea Conventions (OSPAR, HELCOM, Barcelona, and Bucharest Convention) and MSFD regions and subregions, as agreed by the Marine Strategy Framework Directive Committee in November 2016.

Trends in concentrations of nitrogen (dissolved inorganic nitrogen — DIN) and phosphorus (orthophosphate) in the upper 10m of the water column in European seas during the season of low phytoplankton growth (SLPG) are shown for the period 1980-2019. Green circles indicate stations with significant (p<0.05) decreasing trends; orange circles show stations with significant (p<0.05) increasing trends; and grey circles show stations with no significant trends. In these cases, p is a statistical term describing the probability that the trend is significant.

The maps show the temporal development of the ratio between the number of warm-favouring (Lusitanian) fish species and the number of cool-favouring (Boreal) fish species by International Council for the Exploration of the Sea (ICES) statistical area in 5-year intervals from 1985 to 2020.

We all want to know the quality of 'our' local bathing area, beach or lake, and whether it conforms to EU standards. Below you will find a map viewer that will allow you to view on-line the quality of the bathing water in the almost 22 000 coastal beaches and freshwater bathing waters across Europe.

The urban waste water treatment map shows the most recently reported information on the implementation of the Urban Waste Water Treatment Directive (UWWTD). It is based on data from 2018 in EU-28 countries plus Iceland and Norway, which were reported by countries in 2020.

The Water Framework Directive aims to achieve good status for all rivers, lakes and transitional and coastal waters in the EU. Achieving good ecological status for surface waters is critical to this. According to countries’ second river basin management plans, good ecological status had been achieved for around 40% of surface waters (rivers, lakes and transitional and coastal waters) by 2015. However, these plans show only limited improvement in ecological status since the first plans were published in 2009, with ecological status remaining similar for most water bodies.

Ocean surface pH declined from 8.2 to below 8.1 over the industrial era as a result of an increase in atmospheric CO 2 concentrations. This decline corresponds to an increase in oceanic acidity of about 30%. Reductions in surface water pH are observed across the global ocean. Ocean acidification has impacts on marine organisms and has already affected the deep ocean, particularly at high latitudes. Models project further ocean acidification worldwide. The target under United Nations Sustainable Development Goal 14.3 is to minimise the impacts of this by 2030.

All European seas have warmed considerably since 1870, particularly since the late 1970s. During the period for which comprehensive data are available (1981-2018), sea surface temperature increased by between 0.2 °C, in the North Atlantic, and 0.5 °C, in the Black Sea, per decade. This increase is projected to continue, although more slowly than that of air temperature over land. The frequency and magnitude of marine heatwaves has also increased significantly globally and in European seas and is projected to continue, with increasing impacts on ecosystems and climate expected.

The maps show trends in annual 25-percentile of oxygen concentrations in near-bottom waters at stations with at least 6 years of observations in the period 1989-2019, by three classes of DO concentrations: <4mg/l (including <2mg/l class); 4-6mg/l and >6mg/l. Only trends for time series ending after 2000 are included. The chart shows the number of time series with increasing, decreasing and no trend in the North-East Atlantic Ocean and Baltic Sea for the three classes of DO concentrations during the same period (1989-2019).
