Flux Reduction of TCE with use of an EHC® Liquid PRB

The objective of this pilot test was to demonstrate flux reduction of TCE downgradient of an EHC® Liquid permeable reactive barrier (PRB). The flux calculations demonstrated a 73% reduction in 8 months. Advanced techniques such as real-time monitoring, microbial characterization and diagnostics and hi-res imaging were used to characterize and track remedial progress.

Contaminants Treated

TCE, PCE, 1,1-DCA, and 1,1-DCE

SUMMARY

The discharge process of water resulted in chlorinated volatile organic compounds impacted soil and groundwater, primarily TCE. The highest concentrations where located behind the former manufacturing building, where TCE concentrations ranged from 10 to 100 mg/L (ppm). EHC Liquid injections were performed via direct push technology. 

RESULTS

The objective of this pilot test was to demonstrate flux reduction of TCE downgradient of an EHC Liquid Amendment permeable reactive barrier. The flux calculations demonstrated a 73% reduction discharge of TCE 8 months.
