EOS® Permeable Reactive Barriers Treat Trichloroethene Plume
PROBLEM
A large manufacturer in Indiana needed to remediate a long plume of TCE-contaminated groundwater, threatening a river almost 2 miles down-gradient of the source.
PROJECT GOAL
Cut off TCE migration and reduce plume size in an economical, efficient and sustainable manner.
METHODOLOGY
Installation of 6 permeable reactive barriers (PRBs) along the plume transect using EOS® emulsified oil substrates.
RESULTS
To date, the PRBs have effectively cut off the downgradient migration of TCE and continue to reduce overall plume size. EOS® substrate injection resulted in:
• Rapid establishment of reducing conditions within each PRB
• Rapid transformation of TCE
• Formation of TCE daughter products and ethene down-gradient of PRBs
• A growing community of dechlorinating bacteria
