The book describes methods for evaluation and enhancement of the long-term performance of PRB systems, especially of those targeting heavy metals, specifically uranium, and organic contaminants by sorption and/or precipitation mechanisms. Major topics in the book are:
- Selection and characterisation of suitable reactive materials
- Characterisation of the relevant contaminant attenuation processes
- Developing new contaminant-binding chemical compounds ("ligands")
- Accelerated testing methods to assess the long-term performance of the attenuation mechanisms in PRBs
- Evaluation of the influence of site characteristics on PRB performance
- Monitoring of existing and new field installations
- Coupling of electrokinetic techniques and PRB systems
- Large-scale laboratory and field tests and their results
* A systematic approach to investigating the long-term performance of permeable reactive barriers
* Development of new contaminant-binding chemical compounds ("ligands"), accelerated testing methods to assess the long-term performance, and efficiency enhancing electrokinetic techniques
* Extensive data and information on a Hungarian uranium mining facility; once a carefully kept secret of the Soviet Union
