Includes bibliographic references. "To assess whether bioaugmentation (AU) is as biosafe as biostimulation (ST) or natural attenuation (NA), a large-scale aquifer was divided in three lanes for a comparative study in a tetrachloroethylene (PCE)-contaminated groundwater. Results from the first 250 days confirmed that AU was effective for reductive dechlorination to ethene, whereas cis-DCE remained in the effluent from the ST lane and no degradation products were measured in the NA lane. A model amphibian was chronically exposed to effluents the three lanes. Although the froglets had a significantly higher weight compared to the controls, the survivorship and metamorphic transformation were not significantiy by the effluents. This information will be used to help define regulatory requirements for in situ bioremediation approaches"--Abstract.
