From Hydrogen Fuel Cells to High-Altitude-Pilot Protection Suits— Mound Science and Energy Museum Programs Cover a Wide Range of Topics

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.

Evolution of a Groundwater Treatment System—Rocky Flats, Colorado, Site

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.

Thinking Outside the Box: Materials Reuse—Durango, Colorado, Site

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.

Anatomy of a Groundwater Uranium Plume

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.

2014 LM All-Hands Training

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.

LM to Meet Energy Metering Goals Through Enhanced Data Collection at Groundwater Treatment Systems

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.

Analysis of LM Stakeholder Interaction and External Communications

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.

Scientists Assess Damage Caused by Earthquake near Amchitka

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.

Reindustrialization Workshop Held at Mound Site

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.
