This fact sheet summarizes activities of the Federal Remediation Technologies Roundtable (FRTR or Roundtable) over the last year. The FRTR is an interagency working group that promotes cooperation among member agencies to further development and use of new technologies for improved remediation of hazardous waste sites. Primary members of the FRTR include the U.S. Department of Defense (DoD), the U.S. Department of Energy (DOE), the U.S. Department of the Interior (DOI), the National Aeronautics and Space Administration (NASA), and the U.S. Environmental Protection Agency (EPA). The Roundtable meets twice each year to share information on topics of interest and has done so continuously since it was established in May 1990. The 37th FRTR meeting, held in December 2008, focused on green remediation; the objectives of the meeting were as follows: Improve communication, share, experiences and lessons learned in advancing green remediation best practices; and outline key issues, identify baseline, and benchmark green remediation efforts as a basis for future metrics.

This fact sheet highlights ongoing efforts by the FRTR member agencies to better understand characterization and FRTR HIGHLIGHTS Summary and presentations from the . FRTR meeting on Fractured Bedrock Media (November 2010) posted on the FRTR website. remediation in fractured media. The complex geologic nature of fractured media impacts the characterization of such media and the design, implementation, and success of remediation strategies. The complex distribution and connectivity of fractures, joints, conduits, and other discontinuities in the rock, coupled with the large range in their hydraulic properties, results in highly convoluted flow paths over large distances. Fractured rock and carbonate aquifers are also characterized by void space associated with the initial formation of the rock, which influences the long-term retention of contaminants. Recent advances in understanding physical and chemical processes and characterizing groundwater flow and chemical transport in fractured rock aquifers are leading to defensible conceptual site models (CSM) that can minimize the number of monitoring locations, while achieving long-term monitoring objectives. Several characterization and remediation technologies are currently being used both at pilot- and full-scale levels to improve the understanding of these sites. At the 41st FRTR meeting, several such innovative characterization and remediation technologies for use at sites with fractured media were highlighted. In addition, some speakers also recommended changes to management strategies at such sites.

This fact sheet summarizes the activities of the Federal Remediation Technologies Roundtable (FRTR) over the last year. The FRTR is an interagency working group that promotes cooperation among member agencies to promote development and use of new technologies for improved remediation of hazardous waste sites. Primary members of the FRTR include the U.S. Department of Defense (DoD), the U.S. Department of Energy (DOE), the U.S. Department of the Interior (DOI), the U.S. National Aeronautics and Space Administration (NASA), and the U.S. Environmental Protection Agency (EPA). This factsheet highlights work that the FRTR member agencies are doing on VI issues. VI refers to the condition when vapors and gases from contaminated groundwater and soil seep into indoor spaces; these vapors may have the potential to cause health problems. Federal agencies are actively working on understanding the potential for VI at sites, as well as the cleanup and possible health issues raised by VI.

Cleanup of hazardous waste sites can involve significant consumption of gasoline, diesel, or other fuels by mobile and stationary sources. Minimizing emission of air pollutants such as greenhouse gases (GHGs) and particulate matter (PM) resulting from cleanup activities, including those needing fossil or alternative fuel, is a core element of green remediation strategies. Efforts to reduce these emissions during site investigation, remedial or corrective actions, and long-term operation and maintenance (O&M) must meet Clean Air Act (CAA) requirements and state air quality standards as well as requirements of federal and state cleanup programs. Deployment of green remediation BMPs can help reduce negative impacts of cleanup activities on public health and the environment. The CAA currently specifies nitrogen dioxide (NO2), ozone, lead, carbon monoxide (CO), sulfur dioxide (SO2), and PM as the nations criteria air pollutants. EPAs air quality criteria and national ambient air quality standards (NAAQS) for criteria pollutants must be met in all state implementation plans. The Agency has studied impacts of six key GHGs in the atmosphere: carbon dioxide (CO2), methane, nitrous oxide (N2O), hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. Studies found that emissions of these GHGs from new motor vehicles and new motor vehicle engines contribute to GHG pollution threatening public health and welfare.

The US Army Corps of Engineers (USACE) Environmental and Munitions Center of Expertise (EM CX) and their contractor (Tetra Tech) have conducted a Study that follows the process of considering, incorporating, documenting, and evaluating the benefits of green and sustainable remediation (GSR) practices (hereafter referred to as the Study ). The objectives of the Study were to: (1) Follow the consideration and incorporation of GSR practices on Army environmental remediation projects; (2) Ascertain the effectiveness of the GSR practices considered and incorporated; and (3) Provide procedures by which GSR practices shown to be effective can be identified, considered, implemented and documented by Project Teams working on Army sites. This report includes a summary of the Study execution and Pilot Projects, including findings and lessons learned. Recommendations for consideration by the Office of the Assistant Chief of Staff for Installation Management (OACSIM) regarding development of Army-wide GSR guidance and policy, and recommendations for USACE regarding USACE GSR guidance, have been provided separately to the Army and are currently under internal review.
