Project Title:
Enhanced In situ Bioremediation of
Chlorinated Hydrocarbons
Technical Abstract (Limit 200 words)
Soil and groundwater contamination by chlorinated
ethenes, such as trichloroethylene and
dichloroethylene, is a widespread environmental
pollution problem. In many instances, it is standard
practice to excavate and transport the
contaminated soil to a suitable landfill or to
incinerate the soil to remove the contaminant. Such
practices are expensive, environmentally disruptive
and require extensive permitting. On-site and in
situ biological treatment of contaminated soil is a
safer and more economical method of permanently
solving this problem. This proposal describes an
unique in situ treatment method that uses low-cost
reactive micro-particles, introduced into the soil or
ground water to enhance biological degradation of
contaminants by the soil's native microorganisms.
The method has a high potential for public and
regulatory acceptance because of its low
environmental impact. The targeted contaminants
are degraded and the materials that remain in the
soil are environmentally benign. The method is
entirely passive, offering the potential of lower
operating and maintenance costs compared to
existing in situ methods. Adding the particles to the
soil does not require engineering modification of the
site and the flow of ground water is unaffected. If
the Phase I feasibility study is successful, a field
study of the method will be carried out at a NASA
site.
Potential Commercial Applications (Limit 200 words)
The commercial potential of the proposed method
arises from its ability to be used as a primary or
secondary technology for the treatment of
underground formations contaminated with
hazardous organic wastes. The method can be set
up promptly after accidental pollution takes place,
and it has the potential to be easily applied. This
technology can be readily transferred to the
commercial sector.
