| Abstract |
Das 1971 stillgelegte Uran- und Kupferbergwerk Rum Jungle kontaminierte durch aus dem Bergbau, der Aufbereitung und der Haufenlaugung resultierende saure Grubenwässer das Grundwasser und die Vorfluter. Die von 1983 bis 1986 durchgeführten Sanierungsarbeiten werden ausführlich unter Angabe der zeitlichen Veränderung der Meßwerte für den Schadstoffaustrag beschrieben. Das anschließend (bis 1993) realisierte Monitoringprogramm (mit staatlich gestützten Forschungsaktivitäten) zeigte, daß die Sanierung erfolgreich abgeschlossen worden war und alle Anforderungen erfüllte. Gegenwärtig ist ein neues Forschungsprogramm für weitere 5 Jahre angelaufen, bei dem es vorrangig darum geht, eine Quantifizierung der Schadstoffgenerierungsmengen und der Schadstoffbelastung zu erreichen sowie die Transportmechanismen zu untersuchen. |

| Abstract |
Die australische Goldlagerstätte am Mt. Leyshon wird im Tagebau abgebaut. Der Durchsatz der im CIP-Verfahren arbeitenden Goldaufbereitung beträgt 5,5 Mio t/a. Das Problem der Freisetzung saurer Grubenwässer wird langfristig durch selektive Bergeeinlagerungsstrategien und die Oberflächenversiegelung der Halden gelöst. Während der Abbauarbeiten sind jedoch auch unversiegelte Haldenflächen vorhanden, aus denen saure Grubenwässer austreten können. Diese Wässer werden durch ein System von Sammelgräben aufgefangen und einem Wasserauffangbecken zugeführt. Sie werden dort durch Kalkzugabe neutralisiert. Das so gereinigte Wasser gelangt über Pumpen in den Betriebswasserkreislauf zurück. Der Zufluß zum Auffangbecken ist mit regulierbaren Wehren versehen, die bei Hochwasser so gesteuert werden, daß ein Teil der sauren Grubenwässer direkt in die viel Wasser führenden Vorfluter abgestoßen werden kann. Zu dem Rückhaltesystem gehören auch Absetzbecken, die regelmäßig entschlämmt werden. Es ist ein kontinuierliches Monitoringsystem im Einsatz, das eine lückenlose Erfassung der Wassermengen und der Wasserzusammensetzung gestattet. |

| Abstract |
Parts of the Norwegian river Gaula are strongly polluted from former mining activity in the area. In the most polluted parts of the river the concentration levels of Cu and Zn in 1986-1987 were up to 155 mug l-1 and 186 mug l-1, respectively. In 1989 the spoil heaps in the mining area were covered with protective layers of moss-covered plastic. In 1991-1992 the concentration levels of Cu and Zn had decreased by 75% and 65%, respectively. Animal life in the polluted area seemed to be strongly affected by the trace metals in 1986-1987. The 1991-1992 results showed a marked increase in the number of species and in the number of individuals of each species of Ephemeroptera and Plecoptera, compared with the results from 1986-87. Good correlations were found between the concentrations of Cu in the water and both the number of species and the number of individuals of Ephemeroptera and Plecoptera. Analysis of the species Baetis rhodani, Diura nanseni and Rhyacophila nubila showed an average total dry weight content of Cu up to 264 mug g-1, of Zn up to 1930 mug g-1 and of Cd up to 16 mug g-1. The contents of the three trace metals were significantly different from one species to another and in part between the stations for each species. In 1987 trout died after an exposure of one to two days on three test sites in the river, whereas in 1991-1992 40-75% of the trout survived an exposure period of several weeks at two of the sites. Electrofishing in 1991-1992 indicated recolonization of trout in the lower parts of the former affected and uninhabitable area. |

| Abstract |
Parts of the Norwegian river Gaula are strongly polluted from former mining activity in the area. In the most polluted parts of the river the concentration levels of Cu and Zn in 1986-1987 were up to 155 mu g l (super -1) and 186 mu g l (super -1) , respectively. In 1989 the spoil heaps in the mining area were covered with protective layers of moss-covered plastic. In 1991-1992 the concentration levels of Cu and Zn had decreased by 75% and 65%, respectively. Animal life in the polluted area seemed to be strongly affected by the trace metals in 1986-1987.
