Permeable Reactive Barriers
For questions or additional information, contact email@example.com.
The permeable reactive barrier (PRB) is an in situ permeable treatment zone designed to intercept and remediate a contaminant groundwater plume. The PRB provides advantages including that:
As the technology has evolved since the mid-1990s, much has been learned from the installation and operation of more than 200 PRB systems. As a result, the Interstate Technology & Regulatory Council (ITRC) Permeable Reactive Barrier (PRB): Technology Update Team produced the Technical and Regulatory Guidance Document: Permeable Reactive Barriers (PRB): Technology Update (PRB-5, June 2011) to provide an update on information pertinent to the design and use of PRBs for treating contaminants in groundwater. This guidance document, the fifth published by ITRC since 1999 to investigate the development of PRBs as an emerging remediation technology, is a comprehensive resource that incorporates elements from previous documents and provides updates on additional types of reactive media, contaminants that can be treated, PRB longevity issues, and new construction/installation approaches and technologies.

Request for Action: ITRC requests that you and your organization use the Permeable Reactive Barriers (PRB): Technology Update (PRB-5, June 2011) and associated FREE Internet-based training course when considering PRBs as a remedial strategy. Please impart this information to others that you interact with on your sites.
