Abstract

Bioremediation is a cost effective technology that is applicable to many different types of organic and inorganic contaminants. Natural attenuation and enhanced reductive dechlorination are two new methods of bioremediation that are being implemented for site cleanup. Natural attenuation involves biological, chemical, and physical processes that occur naturally and without human intervention to effect site cleanup. Enhanced reductive dechlorination involves the in situ application of electron donors such as molasses, lactic acid, volatile fatty acids, or commercial products to promote biological generation of hydrogen and subsequent reductive dechlorination of organic compounds such as trichloroethene (TCE).
