Groundwater containing legacy contaminants (pollutants that remain after their sources have been controlled) moves through aquifers in response to the hydraulic gradient. As the groundwater moves, contaminants accumulate on solids (e.g., soil, alluvium, and rock). Clean groundwater entering the aquifer upgradient of the site is contaminated by “bleed back” from the solids phases in the soil or rock. Accurate cleanup times are difficult to predict because of this contaminant desorption effect.
The U.S. Department of Energy (DOE) Office of Legacy Management (LM) 2014 All-Hands Training was held the week of July 28, 2014, in Albuquerque, New Mexico. The week included presentations from LM staff and managers, a trip to the National Museum of Nuclear Science & History, teamwork and personal development training, as well as site visits within the Grants Mining District.
The federal government, including the U.S. Department of Energy (DOE) Office of Legacy Management (LM), has been challenged by Executive and DOE orders to reach two goals related to energy usage and metering. The first goal states that LM should reduce energy use intensity (EUI) by 30 percent by fiscal year (FY) 2020, as compared to the FY 2003 baseline. The metering goal was for LM to have 90 percent of its energy use individually metered by FY 2013, a goal that LM will now be able to meet by expanded metering of groundwater treatment systems at its sites.
Dr. Ernest Moniz, the U.S. Secretary of Energy, submitted the U.S. Department of Energy (DOE) Defense-Related Uranium Mines Report to Congress on September 2, 2014. Section 3151 of the National Defense Authorization Act for Fiscal Year 2013 mandated that DOE, “...
The U.S. Department of Energy (DOE) Office of Legacy Management (LM) makes every effort to communicate with its stakeholders through public and small group meetings, conferences, briefings, news releases, telephone, email, informational materials, and the LM website. To assess the effectiveness of communication with stakeholders across the nation, an analysis of stakeholder interaction is performed yearly by LM.
Contractor scientists for the U.S. Department of Energy Office of Legacy Management (LM) traveled to the Amchitka, Alaska, Site in late August to assess the damage caused by a recent earthquake. The 7.9 magnitude event occurred approximately 20 miles north of the island on June 23, 2014. Amchitka Island, near the western end of the Aleutian Islands, is approximately 1,300 miles southwest of Anchorage, Alaska.
The U.S. Department of Energy (DOE) has partnered with local communities to determine the best reuse of land, assets, and facilities, and the Mound-site community is no exception. In May, DOE’s Office of Legacy Management (LM) and the Mound Development Corporation (MDC) co-hosted a reindustrialization workshop at the Mound site in Miamisburg, Ohio.
Uranium contamination in the Great Miami Aquifer—at the Fernald Preserve, Ohio, Site—is being removed from the groundwater through a pump-and-treatment operation, which until this year, involved the operation of 23 extraction wells. Figure 1 shows the footprint of the uranium plume and the 23 extraction wells. Concurrence and support from the U.S.
The foundation of the U.S. Department of Energy (DOE) Office of Legacy Management’s (LM) Goal 4, “Optimize the use of land and assets,” is to establish environmentally sound and protective land uses on LM sites. LM believes there can be beneficial uses of land even though regulatory or other land-use restrictions may be needed. As part of Goal 4, LM will make its lands available for government, public, and private uses, provided such uses maintain cleanup efforts and are consistent with the site remedies, the tenets of sustainability, and the best resource-management practices.
More than 150 participants attended the 2014 Community Leaders Institute (CLI) in Montgomery, Alabama, on April 25 and 26. The event was sponsored by the Medical University of South Carolina; U.S. Department of Energy (DOE); Southeastern Virtual Institute for Health and Wellness; U.S. Department of Defense; the City of Montgomery; EcoLogic Services, Inc.; Project H.E.L.P.; Community Care Network; and Alabama State University.
