摘要：
Groundwater was collected from a petroleum hydrocarbon contaminated site and characterized for microbial and physiochemical properties to assess the feasibility of enhanced natural attenuation. Results demonstrate the depletion of nitrate and dominance of denitrifying bacteria in the groundwater. Microcosm studies of amending nitrate and nutrients were attempted to enhanced biodegradation of petroleum compounds under denitrifying condition. Results show that 75% of petroleum compounds was degraded within 152-day in microcosms amended with nitrate, compared to 25% removal in the non-amended controls. Data indicate that nitrate amendment to groundwater may offer a viable remedy for enhanced natural attenuation of petroleum compounds.
