Abstract:

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. This approach aims to provide two benefits for improving groundwater quality at chlorinated volatile organic carbon CVOC sites by 1. physically reducing the mass flux of contaminants leaving the source zone by using permeation grouting, thereby reducing risk and making the down gradient plume more amenable for management by natural attenuation processes and 2 increasing the Natural Source Zone Depletion NSZD rate within the source by diverting competing electron acceptors around the source zone to create an enhanced reductive dechlorination zone ERDZ.
