Principal Scott Warner contributed a chapter to the recently published Permeable Reactive Barrier: Sustainable Groundwater Remediation. Published by CRC Press, the reference book provides the information needed to plan, design and apply successful, cost-effective and sustainable permeable reactive barrier (PRB) technology.

Scott’s chapter, Two Decades of Application of Permeable Reactive Barriers to Groundwater Remediation, discusses the developments of PRB technology over the past 20 years, including new chemical treatments, performance issues and improvements, cost and sustainability. He argues that PRB is one of the most sustainable treatments used in groundwater remediation today, as the intent of the system is to operate as a hydraulically passive in situ groundwater remedy. Scott was invited to contribute the chapter by the book’s editors following his presentation on the subject at the 2011 CleanUp Conference, sponsored by CRC Care, in Adelaide, Australia.

Scott is one of the industry’s experts on PRB technology, having been a designer of the first commercial PRB application installed in 1994. He was also the project director and lead designer for a PRB installed to remove radioactive Strontium-90 from groundwater at a government site in New York; this project received the 2011 National Ground Water Association Outstanding Remediation Project award. Scott has also led PRB designs for treating groundwater impacted by metals, perchlorate and petroleum hydrocarbon compounds. Additionally, Scott was a developer and instructor for USEPA and state-lead courses on PRBs. He has authored or co-authored more than 50 additional publications on groundwater remediation, hydraulics and geochemistry for both peer-reviewed journals, technical magazines and conference proceedings, and co-edited the 2003 American Chemical Society text, Chlorinated Solvent and DNAPL Remediation: Innovative Strategies for Subsurface Cleanup.
