The Permeable Reactive Barrier: Technology Update (PRB-5, 2011) guidance provides an overview of how to evaluate, design, construct, and monitor permeable reactive barriers (PRBs) at contaminated sites. It covers regulatory considerations, performance goals, reactive materials, design and construction approaches, monitoring, and ways to maintain or improve performance. This guidance also highlights advances in permeable reactive barrier technology, including new treatment materials and innovative installation methods, as well as the benefits and limitations of using permeable reactive barriers. It helps users determine whether a permeable reactive barrier is an appropriate cleanup option for a site and how to better match the technology to site conditions.
This guidance serves as an update and comprehensive resource to the previous Permeable Reactive Barriers: Lessons Learned/New Directions (PRB-4, 2005), Regulatory Guidance for Permeable Reactive Barriers Designed to Remediate Inorganic and Radionuclide Contamination (PRB-3, 1999), Designed Guidance for Application of Permeable Reactive Barriers for Groundwater Remediation (PRB-2a, 2000), and Regulatory Guidance for Permeable Reactive Barriers to Remediate Chlorinated Solvents (PBW-1, 1999).
