xsi:type="gmd:PT_FreeText_PropertyType"><gco:CharacterString>The dataset contains 131 records of water quality analysis from streams in the Spreewitz Glacial Channel, located in the southern reclamation area of the Lusatian Mining District. Over recent decades, acidic mining drainage from former mining areas has led to elevated sulfate and iron concentrations in both groundwater and surface waters. The dataset includes surface water samples collected from 13 locations along the shorelines of the Spree, Kleine Spree, Schwarzer SchÃ¶ps, and Struga streams, all of which drain the post-mining area of the Spreewitz Glacial Channel. Sampling occurred monthly or bimonthly between April 2024 and May 2026. On-site measurements included water temperature, redox potential, pH value and electric conductivity and oxygen concentration. Additionally, laboratory analyses determined the mass concentrations of 35 cations and anions in the water. As the monitoring campaign is ongoing, the dataset will be regularly updated.</gco:CharacterString><gmd:PT_FreeText><gmd:textGroup><gmd:LocalisedCharacterString locale="#locale-ger">Der Datensatz enthÃ¤lt 131 EintrÃ¤ge zur WasserqualitÃ¤t in den FlieÃgewÃ¤ssern der Spreewitzer Rinne, die sich im sÃ¼dlichen Teil des Sanierungsgebiets des Lausitzer Reviers befindet. In den letzten Jahrzehnten hat die Entstehung und Mobilisierung saurer GrubenwÃ¤sser in den Kippenbereichen der BergbauflÃ¤chen zu erhÃ¶hten Sulfat- und Eisenkonzentrationen sowohl im Grundwasser als auch in den Vorflutern gefÃ¼hrt. Der Datensatz umfasst OberflÃ¤chenwasserproben, die an 13 Standorten entlang der Ufer der FlÃ¼sse Spree, Kleine Spree, Schwarzer SchÃ¶ps und Struga entnommen wurden. Diese GewÃ¤sser durchflieÃen bzw. entwÃ¤ssern das bergbauliche Sanierungsgebiet. Die Probenahmen erfolgten monatlich oder zweimonatlich zwischen April 2024 und Mai 2026. Vor-Ort wurden Wassertemperatur, Redoxpotenzial, pH-Wert, elektrische LeitfÃ¤higkeit und Sauerstoffkonzentration bestimmt. ZusÃ¤tzlich wurden im Labor die Massenkonzentrationen von 35 Kationen und Anionen im Wasser bestimmt. Da die Messkampagne fortgefÃ¼hrt wird, wird der Datensatz regelmÃ¤Ãig aktualisiert.</gmd:LocalisedCharacterString></gmd:textGroup></gmd:PT_FreeText></gmd:abstract><gmd:status><MD_ProgressCode xmlns="http://www.isotc211.org/2005/gmd" codeList="http://www.isotc211.org/2005/resources/Codelist/gmxCodelists.xml#MD_ProgressCode" codeListValue="onGoing" codeSpace="ISOTC211/19115">onGoing</MD_ProgressCode></gmd:status><gmd:pointOfContact><gmd:CI_ResponsibleParty><gmd:organisationName><gco:CharacterString>Bundesanstalt fÃ¼r Geowissenschaften und Rohstoffe (BGR)</gco:CharacterString></gmd:organisationName><gmd:contactInfo><gmd:CI_Contact><gmd:address><gmd:CI_Address><gmd:electronicMailAddress><gco:CharacterString>Postfach-B25@bgr.de</gco:CharacterString></gmd:electronicMailAddress></gmd:CI_Address></gmd:address></gmd:CI_Contact></gmd:contactInfo><gmd:role><gmd:CI_RoleCode codeList="http://standards.iso.org/iso/19139/resources/gmxCodelists.xml#CI_RoleCode" codeListValue="pointOfContact">pointOfContact</gmd:CI_RoleCode></gmd:role></gmd:CI_ResponsibleParty></gmd:pointOfContact><gmd:graphicOverview><gmd:MD_BrowseGraphic><gmd:fileName><gco:CharacterString>https://download.bgr.de/bgr/grundwasser/SpreewitzGlacialChannel/Beispielbild/SamplingLocation.png</gco:CharacterString></gmd:fileName></gmd:MD_BrowseGraphic></gmd:graphicOverview><gmd:descriptiveKeywords><gmd:MD_Keywords><gmd:keyword><gco:CharacterString>Natural risk zones</gco:CharacterString></gmd:keyword><gmd:type><MD_KeywordTypeCode xmlns="http://www.isotc211.org/2005/gmd" codeList="http://www.tc211.org/ISO19139/resources/codeList.xml?MD_KeywordTypeCode" codeListValue="theme"/></gmd:type><gmd:thesaurusName><gmd:CI_Citation><gmd:title><gco:CharacterString>GEMET -
