Bioremediation pilot-scale subsurface venting and sparging systems were operated at a low aeration rate at an aviation gasoline spill site. Bioventing removed 99 percent of vadose zone contamination in 8 months with minimal surface emissions. The biosparging process is presently operating and has removed one-third of oily phase residue below the water table in 1 year. The ground water plume has been cleansed of benzene, toluene, ethylbenzene, and xylene (BTEX) components by sparging.
