The use of aerobic bioremediation technologies is most commonly at sites with petroleum hydrocarbons (BTEX, PAHs, TPH), fuel oxygenates and related compounds (MTBE, TBA). By providing a supplemental supply of oxygen to the subsurface through enhancements such as oxygen releasing compounds, the oxygen is made available to aerobic microorganisms in the unsaturated zone, saturated zone or both. Enhanced aerobic biodegradation is suitable for sites with low to moderate levels of contamination. For sites with higher levels of petroleum hydrocarbons, it is often used in conjunction with a more powerful treatment method, such as in situ chemical oxidation (ISCO).
- Examples of Contaminants Treated
- BTEX (benzene, toluene, ethylbenzene and xylenes)
- MTBE (methyl tertiary butyl ether)
- TPH (total petroleum hydrocarbons) from light and heavy fuel oils
- non-halogenated volatile solvents, such as methylethylketone, methanol, ethanol, acetone, ethyl
- Acetate, acetonitrile, tert-butyl alcohol, phenols
- PAHs (polycyclic aromatic hydrocarbons)
- Some halogenated compounds, such as vinyl chloride, chlorobenzenes, high explosives
- Application Methods
- Open pit/excavation post UST and soil removal
- Direct injections in the plume (slurry)
- PRB (permeable reactive barrier)
