Research Transfer Information Research products from EMSP 73784 specifically provide knowledge and information in previously unexplored areas of in situ biostimulation for metal and radionuclide immobilization to support EM’s mission of long-term isolation and in situ remediation of contaminated environments. Specific sites to benefit from this research are Oak Ridge’s Y-12 facility where U and NO3 contaminants are widespread, and Hanford’s 100 area where Cr(VI) resides adjacent the Columbia River. Collaboration Information Program Interaction: EMSP 73784 research members are directly involved in DOE’s NABIR program that seeks innovative microbiological technologies to immobilize toxic metals and radionuclides in situ. The knowledge and the concepts developed in EMSP 73784 will allow larger scale biostimulation endeavors, such as those associated with NABIR, to be successfully implemented at contaminated sites that are plagued with legacy waste.
