(Boston, Mass. – Nov. 14, 2012) – EPA has approved an amendment to the comprehensive cleanup plan to address contamination at the Kearsarge Metallurgical Corporation Superfund Site in Conway, N.H.

The 2012 Record of Decision Amendment will provide a comprehensive approach for the site that addresses all current and potential future risks. The remaining remedial measures will prevent the migration of contaminants from the Site in groundwater and restore groundwater to concentrations at or below the drinking water standards through natural processes.

EPA’s amended plan includes the following major components:

– The remaining groundwater contamination will be destroyed by Monitored Natural Attenuation. A groundwater pump-and-treat system operated for more than 10 years removing more than 99 percent of the contaminants in the subsurface. Modeling demonstrated that the remaining contaminants, less than 3 pounds in the groundwater, will be reduced to drinking water standards by natural processes within 18 years. Groundwater monitoring will ensure that the contaminants do not migrate. If necessary, a contingent remedy will be performed to halt any contaminant migration that does occur;

– The cleanup level for 1,1-Dichloroethane was changed from 3,650 parts per billion (established in the Explanation of Significant Differences issued in Sept. 2003), to 81 parts per billion based on recently established Standards by the State of New Hampshire;

– A cleanup level for 1,4-Dioxane of 3 parts per billion is established based on the recently established Standards by the State of New Hampshire;

– Institutional controls, primarily in the form of Activity and Use Restrictions (AUR) were modified. The existing AUR will be changed to allow non-industrial and non-commercial structures on the property provided that adequate engineering controls are installed on those structures to prevent any real or potential unacceptable exposure to vapors originating from the groundwater contaminants. The existing AUR prevents the use of groundwater at the site.

Five-year reviews will occur to ensure that the remedy continues to be protective of human health and the environment.

More information: Background documents and history of EPA’s work to cleanup contamination at the site are available here.

The entire Administrative Record is also available for review at the Conway Public Library, 15 E. Main Street in Conway, N.H.

EPA awards more than $5.3 million for research fellowships.

Release Date: 11/14/2012

WASHINGTON – Today the U.S. Environmental Protection Agency (EPA) announced more than $5.3 million in research fellowships to 126 students pursuing degrees in environmental studies. The 39 Greater Research Opportunities (GRO) fellows and the 87 Science to Achieve Results (STAR) fellows exemplify the agency’s efforts to improve Science, Technology, Engineering and Mathematics (STEM) education. These fellowships encourage leadership in the nation’s environmental science, research, restoration, pollution prevention and sustainability efforts.

2012 marks the 30th anniversary of the GRO Fellowship program, which is part of the national effort to ensure that the United States continues to graduate students ready to meet environmental science, engineering, and policy challenges. By enhancing and supporting quality environmental education for undergraduate students, the GRO fellowship program encourages promising students to pursue careers in environmental fields and to continue their education beyond the baccalaureate level. Supporting graduate environmental study for masters and doctoral students, the STAR fellowship program provides a steady stream of well-trained environmental specialists that are meeting society’s environmental challenges by performing new environmental research in engineering and in the physical, biological, health, and social sciences.

“These fellowship awards enable undergraduate and graduate students all over the country to pursue research and education opportunities that would otherwise be beyond their means” said Dr. Jim Johnson, director of EPA’s National Center for Environmental Research. “Many of the fellowship opportunities springboard aspiring scientists and engineers into careers in environmental protection.”

EPA is proud of the many research accomplishments of the alumni of the GRO and STAR fellowship programs. “My research into low-cost solar cells was made possible by this fellowship,” said Dr. Cyrus Wadia, a 2002 STAR fellow and currently assistant director for the White House’s Clean Energy & Materials. These programs have helped thousands of students achieve higher education and conduct cutting edge environmental research.

Applications for the fiscal 2013 GRO Program are currently open and applicants have until December 5, 2012 to apply and the STAR fellowships are currently open and applicants have until November 27, 2012 to apply.
