E.T. Slonecker, L.E. Milheim, C.M. Roig-Silva, G.B. Fisher
2012, Open-File Report 2012-1220
Increased demands for cleaner burning energy, coupled with the relatively recent technological advances in accessing unconventional hydrocarbon-rich geologic formations, have led to an intense effort to find and extract natural gas from various underground sources around the country. One of these sources, the Marcellus Shale, located in the Allegheny Plateau,...

Kurt J. Jenkins, Patricia J. Happe, Katherine F. Beirne, Roger A. Hoffman, Paul C. Griffin, William T. Baccus, John Fieberg
2012, Northwest Science (86) 264-275
Mountain goats (Oreamnos americanus) were introduced in Washington's Olympic Mountains during the 1920s. The population subsequently increased in numbers and expanded in range, leading to concerns by the 1970s over the potential effects of non-native mountain goats on high-elevation plant communities in Olympic National Park. The National Park Service (NPS)...

Mercury and halogens in coal--Their role in determining mercury emissions from coal combustion
Allan Kolker, Jeffrey C. Quick, Connie L. Senior, Harvey E. Belkin
2012, Fact Sheet 2012-3122
Mercury is a toxic pollutant. In its elemental form, gaseous mercury has a long residence time in the atmosphere, up to a year, allowing it to be transported long distances from emission sources. Mercury can be emitted from natural sources such as volcanoes, or from anthropogenic sources, such as coal-fired...
