The use of an innovative, passive BTEX remediation technique is being investigated in a pilot study within an existing plume of petroleum hydrocarbons. Previous laboratory and field controlled studies have shown that a proprietary oxygen-releasing compound (ORC) can enhance the dissolved oxygen (D.O.) content of ground water. The field study also demonstrated that at least 4 mg/L each of benzene and toluene could be biodegraded due to the increased D.O. that resulted from the use of ORC. A pilot study undertaken in the summer of 1994 will evaluate the performance of ORC as a passive remediation technique at a plume associated with a retail gasoline outlet. The pilot study will compare several methods to contact the ORC with water and assess the optimal oxygen delivery system: (1) ORC-concrete briquetts, (2) ORC pencils, and (3) ORC trench. The author will discuss the effectiveness of the alternatives at promoting the in situ biodegradation of BTEX compounds and act as a barrier against further plume migration.
