This paper describes passive barriers for controlling downgradient plume migration in contaminated aquifers. Numerous field studies using migration barriers to control benzene, toluene, ethylbenzene, and xylene (BTEX) plumes are briefly summarized. The barriers consist of a patented oxygen release compound placed in a row of wells transecting a BTEX plume. Oxygen is slowly released to the saturated zone, thus enhancing natural biodegradation. Migration is controlled by matching the oxygen release rate to the flux and oxygen demand of the dissolved contaminants.
