– Case Study: How to Avoid Failure in the Design and Installation of Permeable Reactive Barriers

 - 

This talk will showcase innovative and recent advances in the science and technology behind the design and installation of zero-valent iron permeable reactive barriers (PRB) using a real-world case study. Project components to be profiled include:
• Data review and gap analysis for the site;
• Bench-scale proof-of-concept treatability testing;
• Preliminary full-scale design incorporating computer modeling and sensitivity analysis;
• Physical profiling of the PRB alignment at the site using the in-situ Hydraulic Profiling Tool;
• Updated and final detailed design for the full-scale PRB;
• Installation of the “funnel and gate” RB using a biopolymer slurry for excavation support;
• On-site QA/QC testing of the reactive media and emplacement methodology; and
• Follow-up performance monitoring of treatment effectiveness.
