FAQ

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.

Distribution of chemical status of groundwater, rivers, lakes, transitional and coastal waters.: Number of Member States contributing to the dataset: Groundwater (26); Rivers (25); Lakes (22); Transitional (15) and Coastal (20). Percentages shown for rivers, lakes, transitional and coastal are by water body count. Groundwater percentages, however, are expressed by area. The total number of water bodies is shown in parenthesis. Data from Sweden are excluded from surface water data illustrated in the figure. This is because Sweden contributed a disproportionately large amount of data and, classified all its surface waters as poor status since levels of mercury found within biota in both fresh and coastal waters exceed quality standards.
