Abstract:

Hazardous contaminants of heightened concern at DoD sites include the chlorinated solvents tetrachloroethene and trichloroethene, the solventstabilizer 1,4-dioxane, and perfluoroalkyl substances. Recent concern over these contaminants in surface waters and subsurface aquifers is drivenby several factors, including widespread use and improper disposal practices by industry, high miscibility in water, recalcitrance to conventionaldegradation processes, and classification as probable human carcinogens. Current remediation technologies entail ex situ pump-and-treatprocedures that are neither cost effective nor able to effectively remove co-contaminants such as 1,4-dioxane, tetrachloroethene, andtrichloroethene, and perfluorooctanoic acid. The main objective of this work was to develop alternative ex situ and in situ bioremediationtechnologies based on a microbially driven Fenton reaction for degradation of hazardous contaminants at DoD sites.
