Location

Contaminants Treated

PCE, TCE

SITUATIONAL SUMMARY

Prior remediation efforts only temporarily reduced PCE and TCE concentrations in groundwater. Given its combined abiotic and biotic treatment effects, EHC ISCR product was identified as a remedy for the site, and the product formulation was modified for site-specific needs that emerged during the initial implementation.

RESULTS

Significant reductions in concentrations of target compounds was achieved in response to the EHC Fine ISCR product injections. Continued groundwater monitoring indicated that the remedy would be successful in obtaining Clean Up to the Extent Practicable (CUTEP) determination by EPA Victoria.
