Geogenic Groundwater Quality of Germany 1:1,000,000 (GEOGW1000)
The map shows the representative chemical content of groundwater for 22 hydrogeological subregions of Germany. The classification of each sub-region was based on the TDS value (total dissolved solids) and the chemical inventory. According to the degree of mineralization, five classes of waters were distinguished (very small, low, medium, high and strongly changing solution contents). The classification of the waters by their chemical inventory was made according to the equivalent percentage of the main cations and anions based on the Piper quadruple diagram. With this chemical classification and the degree of mineralization, 22 geogenic groundwater types could be differentiated throughout Germany. The basis for the mapping of geogenic groundwater quality is the "Hydrogeological Regions" map. The water quality data comes from the groundwater monitoring networks of the German federal states, which were collected by the State Geological Surveys or the State Environmental Surveys. Further analyses are based on the data of the former Central Geological Institute (ZGI) of the GDR. In total, sample data of nearly 8,000 observation wells have been evaluated.

- Statement
- Grundlage für die Kartierung der geogenen Grundwasserbeschaffenheit ist die Karte "Hydrogeologische Regionen". Die Wasserbeschaffenheitsdaten stammen aus den Grundwassermessnetzen der deutschen Bundesländer, die von den Landesämtern für Geologie/Bodenforschung bzw. Umwelt erhoben wurden. Weitere Analysen gehen auf den Datenbestand des ehemaligen Zentralen Geologischen Instituts der DDR zurück. Insgesamt wurden Proben aus knapp 8000 Grundwassermessstellen ausgewertet.
