Effective Cleanup of Groundwater Contaminated with Radionuclides Using Permeable Reactive Barriers - Permeable Reactive Barrier: Sustainable Groundwater Remediation - page 171

However, the technical feasibility of these processes has already been dem-
onstrated under field and large-scale conditions.
PRBs have shown good removal efficiencies for heavy metals and radionu-
clides. The cleanup of contaminated water bodies, especially river and lake
beds, is still an unsolved problem after radioactive contamination. The appli-
cation of passive remediation technologies like PRBs and most biological in
situ processes, require reliable monitoring systems to ensure that remedia-
tion goals can be reached. The development of new and innovative sensor
systems is therefore also indispensable.
