ABSTRACT
Enhanced In-Situ Bioremediation Process
Earth Tech, Inc
Superfund Innovative Technology Evaluation
EPA 540/MR-00/504
November 2000
The U.S. Environmental Protection Agency (EPA) conducted an evaluation
of the Enhanced In-Situ Bioremediation Process, a biostimulation technology
developed by the U.S. Department of Energy (DOE) at the Westinghouse
Savannah River Plant site in Aiken, South Carolina. DOE has licensed
the process to Earth Tech, Inc. (Earth Tech). The evaluation described
in this bulletin was carried out by the EPA Superfund Innovative Technology
Evaluation (SITE) Program. Earth Tech is utilizing the process to deliver
a mixture of air and gaseous phase nutrients, and/or methane to contaminated
groundwater in fractured bedrock at a site in Roanoke, VA. These enhancements
are delivered to contaminated groundwater via an injection well and
were designed to stimulate and accelerate the growth of existing microbial
populations, especially methanotrophs. This type of aerobic bacterium
has the ability to metabolize methane and produce enzymes capable of
degrading chlorinated solvents and their degradation products to non-hazardous
constituents.
