predating or postdating this period. It comprises analyses of key water quality parameters, such as iron, sulfate, and PTEs (potentially toxic elements). Compiled from historical sources, the digitized dataset has been transformed into a modern geospatial dataset that adheres to the FAIR (Findable, Accessible, Interoperable, and Reusable) principles while also being aligned with the INSPIRE framework for geospatial data interoperability. The dataset underwent comprehensive quality control, standardization, and harmonization procedures to achieve this purpose.</gco:CharacterString><gmd:PT_FreeText><gmd:textGroup><gmd:LocalisedCharacterString locale="#locale-ger">Die vorgestellten Daten stammen aus dem deutschen Teil der Lausitz und wurden Ã¼berwiegend zwischen 1950 und 1995 erhoben, wobei einige wenige DatensÃ¤tze aus der Zeit vor oder nach diesem Zeitraum stammen.
