The U.S. Department of Energy has asked for public comment about a proposed plan to reduce groundwater contamination in the main plant area of East Tennessee Technology Park, the former K-25 site in west Oak Ridge.

Comments are for an interim record of decision. There will be a public meeting Tuesday evening in Oak Ridge.

“The proposed plan identifies enhanced in situ bioremediation (EISB) as DOE’s preferred alternative to remediate six specific areas of groundwater in the main plant area of the East Tennessee Technology Park,” DOE said in a public notice distributed by the Tennessee Department of Environment and Conservation. “EISB is a method that involves using microorganisms to reduce contamination levels in these specific areas of groundwater. For these six areas, workers have excavated, or will excavate, the primary sources of contamination, as specified in the Record of Decision for Soil, Buried Waste, and Subsurface Structure Actions in Zone 2, East Tennessee Technology Park, Oak Ridge, Tennessee (DOE/OR/01-2161&D2).

A manager in the Fossil Energy Program at Oak Ridge National Laboratory will discuss the environment and hydraulic fracturing, often referred to as “fracking,” during a Monday meeting.

Joanna McFarlane, who has a doctorate, is a manager for the RPSEA (Research Partnership to Secure Energy for America) and Environmentally Friendly Drilling in the Fossil Energy Program at ORNL.

She will give a presentation on “Hydraulic Fracturing and the Environment” during a meeting at 11:30 a.m. Monday, January 26. It’s a luncheon meeting of the AAUW Oak Ridge Branch. The group will meet in the Activities Building of First Presbyterian Church at the corner of Oak Ridge Turnpike and Lafayette Drive. [Read more…]

DOE responds to advisory board recommendation
 on groundwater studies

The U.S. Department of Energy’s Oak Ridge Office of Environmental Management has responded to a recommendation made earlier this year by the Oak Ridge Site Specific Advisory Board.

In May, the federally appointed citizens’ panel recommended that DOE conduct additional groundwater studies to address any potential offsite migration of chemicals or radioisotopes from DOE’s Oak Ridge Reservation. The recommendation focuses on developing information that fosters a better understanding of potential impacts of groundwater contamination related to risk mitigation, groundwater remediation, and long-term stewardship.

In 2013, DOE, the Environmental Protection Agency, and the Tennessee Department of Environment and Conservation held a series of workshops to prioritize groundwater pathways on the ORR. Together the agencies created a groundwater strategy document that described the potential for releases from waste disposal sites and storage areas. The document also prioritized known groundwater plumes, concentration of contaminants, contaminants of concern, and potential health risks. [Read more…]

DOE commits to three-year, $4.5 million groundwater study in Oak Ridge

Daniel Goode and SSAB Groundwater Strategy Presentation

Daniel J. Goode, a research hydrologist for the U.S. Geological Survey, briefs members of the Oak Ridge Site Specific Advisory Board on a new groundwater strategy for the Oak Ridge Reservation.

The U.S. Department of Energy has agreed to spend $4.5 million during the next three years to study groundwater contamination on the Oak Ridge Reservation.

The reservation includes three federal sites—East Tennessee Technology Park, Oak Ridge National Laboratory, and Y-12 National Security Complex—that have been involved in missions ranging from scientific research to uranium enrichment to nuclear weapons work. That work has sometimes included the use of hazardous substances such as mercury and technetium-99, a slow-decaying radioactive metal.

The $4.5 million in funding will help implement a new groundwater strategy developed by DOE with help from the Tennessee Department of Environment and Conservation and the U.S. Environmental Protection Agency.

The strategy, which was presented to the Oak Ridge Site Specific Advisory Board in November, will help guide future cleanup decisions, said Sue Cange, deputy manager for environmental management in DOE’s Oak Ridge Office. [Read more…]

A citizens’ panel will discuss a strategy document tonight that outlines possible solutions for managing contaminated groundwater on the federal reservation in Oak Ridge.

It’s the focus of a 6 p.m. meeting of the Oak Ridge Site Specific Advisory Board. The strategy document was developed to address problems with contaminated groundwater on the U.S. Department of Energy’s Oak Ridge Reservation.

The meeting is in the DOE Information Center in the Office of Science and Technical Information on Oak Ridge Turnpike. The public is welcome to attend. OSTI is between Science.gov Way and Melton Lake Drive. [Read more…]
