Description:
Soils and ground water beneath the U.S. Coast Guard Air Station at Traverse City, MI, have been contaminated with separate spills of aviation gasoline and JP-4 jet fuel. Contamination from both plumes has affected a shallow water table aquifer consisting of a medium grained sand. This site has been the location of a cooperative effort between the U.S. Coast Guard and U.S. EPA to extensively characterize the site to determine three dimensional extent of contamination, local hydrogeology, geochemistry of the solids and water, and nature of microbial activity. Evaluation concerning feasibility and cost of three innovative bioremediation techniques has also been completed at the Air Station. One evaluation demonstrated the use of hydrogen peroxide as the electron acceptor to enhance aerobic biodegradation in a portion of the aviation gasoline area. Nitrate was used as the electron acceptor hr a portion of the JP-4 jet fuel contamination. Bioventing of a second portion of the aviation gasoline contamination was the third innovative technique evaluated. Each treatment reduced benzene levels to less than 5 ug/L, with 25% to 60% reduction in total fuel levels. For these evaluations, bioventing had the lowest capital and operating costs, followed by nitrate addition and finally hydrogen peroxide.
