Intrinsic bioremediation of TCE and petroleum hydrocarbons, MacDill AFB, FL.

摘要

A dissolved TCE groundwater plume in the water table aquifer at MacDill AFB, FL is naturally degrading as it passes through hydrocarbon contamination from two downgradient petroleum release sites. The presence of hydrocarbons, cis-1,2 dichloroethylene (DCE), and vinyl chloride, which are TCE transformation byproducts, in the shallow sandy aquifer downgradient of the apparent source area suggests the potential for reductive dechlrination of TCE. Analysis of groundwater for intrinsic remediation parameters strongly indicates that natural degradation is occurring. A hybrid remedy has been proposed for the site: monitored natural attenuation (MNA) and source area reduction are being considered to address groundwater, while bioventing has been selected for remediation of petroleum-contaminated soils.
