CASE STUDY: HOW TO AVOID FAILURES IN THE DESIGN AND INSTALLATION OF PERMEABLE REACTIVE BARRIERS
French, K. | SustainTech, 21 March, Saskatoon, Saskatchewan, 2019, 46 slides.

This presentation discusses a case study using a permeable reactive barrier (PRB) to remediate groundwater contaminated with chlorinated VOCs under a parking lot. Bench-scale studies and high-resolution site characterization were used to finalize the PRB design, which consisted of 30% zero-valent iron (ZVI) in a 0.9 m-thick PRB. The PRB was installed over 6 days and consisted of course sand and ZVI mixed in a cement truck before placement. Post-placement monitoring from 2012-2017 showed that all contaminant concentrations met site goals. https://www.seima.sk.ca/resources/Documents/SustainTech%202019%20Presentations/SustainTech%20Kevin%20French%20presentation%202019%20(2).pdf
