The Environmental Remediation Sciences Division (ERSD) merges with the
Climate Change Science Division
(CCSD) within BER
On June 24, 2008 ERSD merged with CCSD to become the Climate and Environmental Sciences Division (CESD). Current programs and program leads within both former divisions remain the same in the new combined division (http://www.sc.doe.gov/ober/CCRD_top.html). This change will help to improve coordination among BER programs on climate and earth systems.
Hanford Demonstrates Bioimmobilization of Hexavalent Chromium in Ground Water
The U.S. Department of Energy (DOE) is evaluating long-term efficacy of lactate-stimulated bioreduction to treat ground water contaminated with hexavalent chromium [Cr(VI)] at Hanford's "Site 100H" along the Columbia River in Washington. The study includes identification of critical microbial community-structure changes and stressors helping to control and predict biogeochemical processes causing Cr(VI) bioimmobilization. Polylactate in the form of Hydrogen Release Compound® (HRC) was injected into the ground water in 2004. Cr(VI) concentrations now are below the drinking water standard of 10 ppb due to transformation of Cr(VI) into insoluble Cr (III) complexes, which is largely affected by bioimmobilization stressors. Common stressors identified during the study include oxygen, nitrate, salt, and sulfate. Department.
"Modern Marvels" Program on the History Channel to Feature Bioremediation Research at the FRC
Airing Wednesday night, January 24, 2007
The History Channel Modern Marvels show (Environmental Tech series) will include a segment on the in situ bioremediation research being conducted at the DOE ERSP Oak Ridge Field Research Center. It is scheduled to air Wednesday January 24th at 10:00 PM eastern time (see below for additional information on airdates). We were approached by the show's producer (Anthony Lacques) after he discovered the FRC through a web search on the topic. Filming at the FRC Area 2 and 3 sites was conducted October 24, 2006 after obtaining all the needed clearances from DOE, ORNL, and Y-12. The show has footage of the following:
- Interviews with David Watson, Philip Jardine, Tony Palumbo, and Ed Uberbacher on use of bioremediation technology for metals and radionuclides
- Drilling and sampling with the FRC's drilling rig
- Scanning of samples with pancake meter and XRF
- Clips from inside a well obtained with our borehole camera
- Phil Jardine giving a tour of the above ground pretreatment equipment (e.g., fluidized bed reactor etc) in the Area 3 tent
- Information on the DOE legacy waste contamination problems
- File footage of DOE historical operations and pictures of the S-3 Ponds
- Several animations prepared by the History Channel showing how contaminants migrate to groundwater and the concept of bioremediation (e.g., electron transfer to reduce valence state and mobility)
Wednesday, January 24th:
10:00 pm (Eastern/Pacific Times)
9:00 pm (Central Time)
8:00 pm (Mountain Time)
It will also be re-airing after that, although we do not have those dates yet.
Please check your local television directory as well, as the times may differ for those with certain satellite providers. You can also visit the History Channel website for further information.
