Ecosystem-level Evaluation of Intrinsic Contaminant Bioremediation and Impact ofNaval Shipyards on Adjacent Ecosystems: A Preliminary Report

摘要

The objective of the project is to determine the extent to which intrinsicbioremediation is occurring in groundwater contaminated with gasoline (benzene, ethylberizene, toluene, and xylenes; 3TEX), methyl-tertbutyl ether (MTBB), and trichloroethylene (TCE). Preliminary findings suggest that the comingled contaminant plumes have significant bacterial productivity and contaminant mineralization rates. Rapid bacterial production and benezene turnover rates at wells, which are down gradient of the other BTEX plume(s) suggests that the natural bacterial assemblage has the capacity to inhibit migration of the plume towards Noisette Creek.
