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.
