SOURCE BARRIER TOOL: CONTAMINANT FLUX REDUCTION BARRIERS FOR MANAGING DIFFICULT-TO-TREAT SOURCE ZONES IN UNCONSOLIDATED MEDIA
Newell, C.
ESTCP Project ER-201328, 111 pp, 2018

This tool explains the potential benefits of a physical barrier around a chlorinated solvent source zone and helps the user understand if a barrier would work at a particular site. The overall objective of this project was to evaluate if inexpensive flow reduction agents delivered via permeation grouting technology could help manage difficult-to-treat chlorinated solvent source zones, or any other source zone comprising contaminants that degrade primarily via anaerobic biodegradation processes inhibited by naturally occurring competing electron acceptors, such as oxygen and sulfate. https://www.serdp-estcp.org/content/download/48809/465123/file/ER-201328%20Source%20Barrier%20Tool.pdf
