Demonstration of Bioaugmentation at Kelly AFB, TX
Demonstration of Bioaugmentation at Kelly AFB TX Author:Bruce Alleman, Matt Place, David Major This is a AIR FORCE RESEARCH LAB TYNDALL AFB FL MATERIALS AND MANUFACTURING DIRECTORATE report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report num... more »ber is A333624. The abstract provided by the Pentagon follows: Bioaugmentation is an innovative technology designed to promote complete reductive dechlorination at sites where natural attenuation or enhanced anaerobic dechlorination cannot achieve the level of contaminant destruction to protect human health and the environment. Enhanced anaerobic bioremediation through the addition of electron donors and/or other nutrients is being demonstrated in the field at an increasing number of sites where the geochemical environment cannot support natural attenuation. While the technology has been able to achieve the anaerobic conditions necessary for halo respiration, the sites do not exhibit complete dechlorination, most commonly due to microbial limitations. Recently, bioaugmentation has been demonstrated successful for achieving complete dechlorination at Sites where delivery of donor/nutrient amendments resulted in limited success. One such site is the Building 360 Site at Kelly AFB, Texas where dechlorination of trichloroethylene (TCE) was demonstrated to hold up at cis-dichloroethylene. The Environmental Security Technology Certification Program funded a study to test the robustness of the bioaugmentation technology. The objectives were to investigate the survivability of the KBI culture, evaluate any residual dechlorinating activity, attempt to reestablish the level of activity to pre-shutdown levels, and to Stress the culture by adding sulfate.« less
