Permeable Reactive Barrier (PRB)

GeoPro Talks – Permeable Reactive Barriers Just Keep Getting Better: How To Keep Up With The Times

May 4th, 2022 by

A Permeable Reactive Barrier (PRB) is an engineered zone installed below ground to remediate migrating groundwater impacts. This presentation will serve to outline an improved approach to PRB design that takes advantage of the current state of knowledge and technology in the environmental industry. Aspects that will be discussed in the talk include:

  • Necessary site characterization data inputs
  • High-resolution PRB alignment profiling
  • Desktop modeling and preliminary design
  • Bench-scale PRB design testing and optimization
  • Detailed design and sensitivity analysis
  • Installation techniques, including in fractured bedrock
  • New QA/QC test methods for reactive media, including AC amendments

Examples of recently completed projects will also be presented and discussed.

It is hoped that this updated approach will serve as a roadmap for environmental practitioners to increase the certainty of performance and cost-effectiveness for all types of PRBs such that their long-term risk management objectives are achieved.

Mr. French is Vice President of Vertex Environmental Inc. and has over 30 years of experience and expertise in environmental engineering, specializing in site assessment and remediation. Kevin has been involved in the design and implementation of remediation programs across Canada involving permeable reactive barriers, adsorptive technologies, in-situ chemical oxidation and reduction, aerobic and anaerobic biodegradation, etc. in soil, groundwater and bedrock for a variety of contaminants, including petroleum hydrocarbons, chlorinated solvents, heavy metals and other compounds.
