Das in Talsperren gespeicherte Wasser sichert unsere Trinkwasserversorgung. Gute Wasserqualität ist dafür wichtig - wird aber durch den Klimawandel stark gefährdet. Ein Forschungsteam des Helmholtz-Zentrums für Umweltforschung (UFZ) konnte in einer Modellstudie an der Rappbodetalsperre im Harz zeigen, wie sich der klimabedingte Waldverlust etwa durch Waldbrände im Einzugsgebiet der größten Trinkwassertalsperre Deutschlands auf die Wasserqualität auswirken kann. Solche indirekten Folgen des Klimawandels seien ein stark unterschätztes Problem, mahnen die Wissenschaftler:innen im Fachjournal Water Research an. Gerade für Trinkwassertalsperren ist die Wasserqualität hochrelevant, da die anschließende Aufbereitung im Wasserwerk kontinuierlich hohe Standards erfüllen muss.
