Halogenated organic compounds (organohalides) have often
been released into the soil and groundwater. These compounds may be carcinogenic
and are hazardous to the natural environment. A significant need exists
therefore for techniques to efficiently decontaminate these types of toxic
compounds.
Researchers at the Biodesign Institute of Arizona State
University have developed methods and systems for dehalogenating organohalides
present at contamination sites. Dehalogenation of contaminants can be achieved
by providing hydrogen to anaerobic dehalogenating bacteria. Hydrogen can readily
be created in situ through the electrolysis of water.
The method is efficient, inexpensive, renewable, and enables
onsite decontamination of water and soil.
Potential Applications
- Groundwater treatment systems
- Water purification
- Wildlife preservation
- Contamination prevention
Benefits and Advantages
- Adaptable to different conditions at particular sites
- In situ decontamination
