T1 - Evaluation of long-term aspects of passive groundwater remediation techniques T2 - Proceedings of the 1st Image-Train Cluster-Meeting 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.
