Abstract
A biological barrier was installed in a MTBE / BTEX plume at the Naval Base
Ventura, Port Hueneme, California to demonstrate the effectiveness of four
different barrier configurations on dissolved plume treatment. The barrier spans
the 500-ft wide plume, and is configured to illustrate the treatment potential of
both in situ air sparging (IAS) alone as well as two variations of the enhanced
MTBE bioremediation (EMB) in situ process on MTBE and mixed MTBE/BTEX
dissolved plumes. Contaminant monitoring after three months of operation show
MTBE concentration decreases of at least an order of magnitude in the most
contaminated zone. BTEX concentrations are reduced by an order of magnitude
in the MC-100 seeded zone, while reductions in the SC-100 plot are slightly less
