ITRC Advanced Techniques on Installation of Iron Based Permeable Reactive Barriers and Non-Iron Based Barrier Treatment Material
2002

This is the second training on Permeable Reactive Barrier Walls from the ITRC. It responds to student requests to provide additional detail and describe advancements in the science and engineering to design, install, maintain and monitor reactive barrier systems. This curriculum will train students using case studies to describe long-term performance of iron-based systems and design them according to the heterogeneities of the subsurface. Construction techniques for excavation and barrier wall emplacement have improved dramatically and careful attention to barrier design & construction is critical to long term performance monitoring. This training is designed for State and Federal regulators and the practicing consultants. Site owners and community stakeholders will find this new information interesting as well. The training does not focus on the basic science and engineering of barrier systems but does present information from industry and State regulators using up to date case studies to document the data. This training also describes non-iron barrier systems, the material most commonly used and the mechanisms encouraging a reduction in contaminant concentrations with in the systems.

ITRC Permeable Reactive Barriers for Chlorinated Solvent, Inorganic, and Radionuclide Contamination
2002

This training is designed to introduce state regulators, environmental consultants, site owners and community stakeholders to three documents created by the ITRC's Permeable Reactive Barrier Walls Technical Team and the Remediation Technologies Development Forum (RTDF) Bioremediation Consortium titled, 'Regulatory Guidance for Permeable Barrier Walls Designed to Remediate Chlorinated Solvents', 'Regulatory Guidance for Permeable Reactive Barriers Designed to Remediate Inorganic and Radionuclide Contamination' & 'Design Guidance for Application of Permeable Barriers to Remediate Dissolved Chlorinated Solvents'. The training focuses on the basic information one needs to determine and document the conditions necessary to effectively apply a permeable reactive barrier to a contaminated zone to be an effective part of remediating chlorinated solvents, radionuclides and other inorganic compounds in ground water. It provides a framework, that is, how to think about permeable reactive barriers based on science. The information contained in this manual and presentation is based on research activities of the RTDF and from experience and knowledge of the participating members.

ITRC Permeable Reactive Barriers: Lessons Learned and New Directions
2006

This training presents updated information regarding new developments, innovative approaches, and lessons learned in the application of PRBs to treat a variety of groundwater contaminants. The information will be presented by reviewing the approaches and results at several sites where PRBs have been deployed. The training is based on the ITRC guidance document titled Permeable Reactive Barriers: Lessons Learned / New Directions (PRB-4, 2005). Case studies from around the country are included in the training to show various designs, contaminants, reactive media, and cost data for PRB systems. The training provides new information on iron-based PRB systems while providing a solid introduction to the non-iron PRBs.

This tool summarizes the history and key scientific concepts associated with the use of PRBs and reviews the steps necessary for PRB implementation at a field site. It provides key information in the following areas: (1) appropriate sites for PRB installation, (2) available design and construction techniques, (3) expected lifespan and economic benefits estimation, and (4) monitoring programs to track PRB performance and help comply with regulatory guidelines.

Permeable Mulch Biowalls
U.S. Navy, Naval Facilities Engineering Command, Environmental Restoration Technology Transfer, Multimedia Training Tools website.

A biobarrier provides a biologically active treatment zone rather than the chemically reactive treatment zone commonly found in PRB technology. This Web tutorial reviews design and installation considerations for permeable mulch biowalls and highlights case study results at Navy and Air Force sites.
