OSTI ID:895318
The objective of this report is to perform field investigations to assess the potential for immobilizing and detoxifying chromium contaminated soils and groundwater using bioremediation at Site 100H at Hanford. Specific goals are: (1) Designing a field test to measure the effect of lactate biostimulation on microbial community activity, redox gradients, transport limitations, and other reducing agents in comparison with our previous NABIR laboratory work. (2) Establishing the rates and conditions that may cause are oxidation of Cr(III) to Cr(VI) following biostimulation. (3) Providing design criteria for full-scale deployment on in situ Cr(VI) bioreduction via lactate stimulation for use at DOE sites.
