To meet the growing challenge of groundwater pollution we need to look beyond traditional methods of clean up to "alternative" technologies. Permeable reactive barriers (PRBs) have had success in the remediation of chlorinated solvent contaminated ground–waters and are now recognised for the treatment of other contaminants, both inorganic and organic. Innovations in the field and the long-term performance of PRBs are the focus of this volume.

In the foreword Bob Gillham concludes that the contributions in this volume, and the conference from which they were derived, provide considerable insight concerning the evolution of the PRB technology. With the maturation of the technology, as reflected in these topics, it appears certain that PRBs will continue as a significant remediation technology and that their stature and acceptance is likely to increase in the future.
