WISE Groundwater: A GWB is defined in WFD Art. 2 as a distinct volume of groundwater within an aquifer or aquifers, whereas an aquifer is defined as a geological layer with significant groundwater flow. This definition of a GWB allows a wide scope of interpretations. The submission of GWB data to the Commission by the EU Member States was accomplished via the Reportnet platform, as a part of the dataflow for WFD. Art. 13 reporting. GWB data includes spatial data as GIS polygons and GWB characteristics in an XML schema. GWBs are registered to so-called horizons, which represent distinct vertical layers of groundwater resources.

Proportion of classified water bodies in different RBDs affected by hydromorphological pressures, for rivers and lakes (left panel) and for coastal and transitional waters (right panel): The percentage is based on total number of classified water bodies. See the indicator specification for more details.

Proportion of total number of classified water bodies with identified significant pressures (left column) and impacts (right column), for rivers, lakes, coastal waters, and transitional waters: The percentage is calculated against the total number of classified surface water bodies in Member States reporting the specific pressure or impact type (or any pressure or impact for the blue bars). The number of Member States included is indicated in brackets. See the indicator specification for more details.

Impacts and pressures (WFD 001) - Assessment DRAFT created Apr 2013: The pressures reported to affect most surface water bodies are pollution from diffuse sources causing nutrient enrichment, and hydromorphological pressures causing altered habitats. Lakes are generally least affected by pressures and their impacts. Pollution from diffuse sources is reported for a larger proportion of water bodies than pollution from point sources for all water categories except transitional waters. The highest proportion of water bodies affected by hydromorphological pressures and altered habitats impact is found for rivers.

Hazardous substances in Europe's fresh and marine waters — An overview: Chemicals are an essential part of our daily lives and are used to produce consumer goods, to protect or restore our health and to boost food production, to name but a few examples. Some chemicals, however, are hazardous, raising concerns for the environment and human health. Hazardous substances are emitted to fresh and marine waters via a number of pathways and can have detrimental effects on aquatic biota. Humans can be exposed to hazardous substances in water through the ingestion of contaminated drinking water and the consumption of contaminated freshwater fish and seafood. A wide range of legislation now exists in Europe to address the release of hazardous substances to the environment, including water. New challenges exist, however, including the issues of chemical mixtures and emerging pollutants.
