The U.S. Department of Energy (DOE) Office of Legacy Management (LM) manages nearly 40 years of legacy site environmental records, generated since the days of the Cold War. These key LM assets must be managed and maintained efficiently and effectively, so the applications, respective systems, and processes currently being used are undergoing significant Next Generation (NextGen) upgrades to improve future operations.
The U.S. Department of Energy (DOE) Office of Legacy Management (LM) experienced a 19 percent increase in the total number of stakeholder requests from fiscal year (FY) 2013 to FY 2014, according to Dr. Edwin Parks, LM Program Analyst.
LM provides stakeholders with information in response to Freedom of Information Act (FOIA), Privacy Act, Energy Employee’s Occupational Illness Compensation Program Act (EEOICPA) claims, and other routine requests.
On a late June afternoon on the high desert east of Tuba City, Arizona, members of a Navajo family scoot along the sand riding all-terrain vehicles, rounding up their horses under a ceramic-blue sky. Across a dune ridge, Quentin Benally wipes his brow, adjusts his camo sun hat, and for the umpteenth time, leans over a 25-meter tape measure stretched across the desert floor and calls out the scientific names of plants. His associate stands nearby with pen to paper.
The Eighth Annual National Conference on Health Disparities was held November 5 through 8, 2014, in Long Beach, California. Like past conferences, it focused on policies and programs to reduce health disparities. However, the 2014 session saw one panel address a new topic—the impact of health issues, including disparities, on our nation’s military personnel and national security.
The Mound Science and Energy Museum (MSEM) is an active, volunteer-led organization located at the former U.S. Department of Energy (DOE) Mound site in Miamisburg, Ohio. MSEM keeps the 60-year history of scientific discoveries, inventions, and ingenuity of Mound site workers alive.
A project to reconfigure the East Trenches Plume Treatment System (ETPTS) at the Rocky Flats site, to improve treatment effectiveness and meet the strict water quality standards in the area, is scheduled to be completed in January 2015. The ETPTS was installed in 1999. The system was designed to intercept and treat groundwater contaminated with chlorinated solvents, chemicals commonly used in dry cleaning and to clean tools. At Rocky Flats, the solvents were used primarily as degreasers and lathe and machining coolants.
When the permeable reactive barrier treatment system associated with the Durango disposal cell toe drain was removed in 2010, the perimeter fence was also removed and the materials were stockpiled outside of the evaporation pond fence line. Plans at the time were to eventually recycle the materials.
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.
