Applying Bioaugmentation to Treat DNAPL Sources in Fractured Rock

Abstract

Management of fractured rock sites impacted by chlorinated solvents remains one of the top environmental challenges for the Department of Defense (DoD). These chlorinated solvents, such as tetrachloroethene (PCE) and trichloroethene (TCE), are used as industrial degreasers and cleaners, (TCE), and cause many unintended discharges and improper disposal practices that affect fractured rock sites. This has resulted in subsurface impacts that produced regulatory exceedances in both soil and groundwater. The use of anaerobic bioremediation as treatment for chlorinated ethenes such as PCE and TCE has been one of the most widely and successfully applied in situ treatment technologies for this class of contaminants. While applying bioaugmentation to treat chlorinated solvent DNAPL sources in fractured rock continues to be a challenge, tools and approaches have been developed to mitigate the difficulty associated with these sites.
