Boron background values in groundwater in Lower Saxony 1 : 500,000 (WMS service)
Description
Background values for dissolved boron in groundwater were determined for the hydrogeological subregions of Lower Saxony (Elbracht et al., 2016) in order to fulfil the tasks of the EC Water Framework Directive (EC Water Framework Directive) and the Groundwater Ordinance (GrwV). The background values of dissolved boron include the levels that occur under natural conditions due to the contact of the groundwater with the surrounding rock matrix of the aquifer. The map shows the boron background values of the hydrogeological subregions of Lower Saxony in different colours. The classification is based on the applicable de minimis thresholds (JRC) of the Länderarbeitsgemeinschaft Wasser (LAWA), the limit values of the Drinking Water Ordinance (TrinkwV) and the guidelines of the World Health Organization (WHO). Selecting a subspace leads to further information (e.g. number of samples, summarized subspaces, etc.).
Background values are not current measurements of groundwater quality and cannot be used as such!
