T1 - Evaluation of long-term aspects of passive groundwater remediation techniques N2 - Long-term performance of permeable reactive barriers has been investigated in laboratory experiments using elemental iron and hydroxyapatite as reactive materials and uranium as contaminant. Accelerated testing has been performed by applying elevated pollutant concentration and an increased flow velocity. The spatial distribution of uranium in the test columns has been investigated using a radioactive tracer. The results show that the migration pattern exhibits a linear behaviour.

A1 - Simon, Franz-Georg A1 - Biermann, Vera T1 - Sustainable environmental protection N2 - Permeable reactive barriers (PRBs) offer an alternative as opposed to more cost-intensive active methods for groundwater remediation, e.g. pump-and-treat. Long-term performance of PRBs, however, is crucial for the technology’s success. The paper summarises the results of long-term column experiments with elemental iron (Fe0) and hydroxyapatite (HAP) as reactive materials for the removal of uranium from groundwater. Good removal results have been achieved using elemental iron with possible reaction paths being reductive precipitation and adsorption on to corrosion products of Fe0.

T1 - TAILSAFE - Investigation and improvement of tailings facilities N2 - Improperly built or managed tailing dams pose major risks to human lives and the environment. Research for risk reduction by new technologies including slurry handlings, stochastic modelling, development of a parameter framework as well as work on legislation and authorisation procedures will be done in the EC-funded project TAILSAFE. Focus of this paper is on geophysial techniques for structure investigation and monitoring.

T1 - TAILSAFE - Investigation and improvement of tailings facilities N2 - Tailings are the fine residue of the milling process in the mining industry and appear in slurry form being mixed with water during this process. Large tailings ponds are required to contain them, usually confined by man-made dams. Such tailings facilities pose considerable risk both to the environment and human lives. A major interdisciplinary research project ('TAILSAFE') supported by European Union has been initiated with the aim to increase attention towards and reduce the risk posed by tailings facilities. Methods of parameter evaluation and measurement are being developed within the project and applied for the detection, assessment and improvement of the safety state of tailings dams and ponds. One of the workpackages has his focus on non-destructive geophysical investigation methods. Geoelectrical (SIP), seismic and radar methods will be used to get information on the tailings dam structure and water content.
