Characterization and modes of occurrence of elements in feed coal and fly ash; an integrated approach
Michael E. Brownfield
2002, Fact Sheet 038-02
Despite certain environmental concerns, coal is likely to remain an important component of the United States energy supply, partly because it is the most abundant domestically available fossil fuel. One of the concerns about coal combustion for electricity production is the potential release of elements from coal and coal combustion...

The area offshore of New York City has been used for the disposal of dredged material for over a century. The area has also been used for the disposal of other materials such as acid waste, industrial waste, municipal sewage sludge, cellar dirt, and wood. Between 1976 and 1995, the...
Occurrence of bacteria in Blue Marsh Lake and selected tributaries, Berks County, Pennsylvania: September-October 2001
Michele L. Zimmerman
2002, Fact Sheet 036-02
The Commonwealth of Pennsylvania has water-quality standards that limit the number of specific bacteria in water that is considered safe for recreational use. Bacteria such as fecal streptococci, fecal coliforms, and Escherichia coli (E. coli) are used to assess recreational water quality because they usually live in the intestines of...

Bryophytes and lichens: Small but indispensable forest dwellers
Martin Hutten, Andrea Woodward
2002, Fact Sheet 154-02
* What is a Bryophyte? * Bryophytes are the small green plants commonly known as mosses, liverworts and hornworts. Compared to plants, they have primitive tissues for conducting food and water, and they lack a protective outer surface to maintain water balance. Most bryophytes, because they lack tissues such as roots,...
Loss of sagebrush ecosystems and declining bird populations in the Intermountain West: Priority research issues and information needs
Water Resources Division, U.S. Geological Survey
2002, Fact Sheet 122-02
Sagebrush lands in the Intermountain West are declining rapidly in quality and extent. Consequently, populations of many bird species dependent on these ecosystems also are declining. The greater sage-grouse has been petitioned for listing as a threatened and endangered species, and other species of sagebrush-obligate birds have special conservation status...

Born of fire - restoring sagebrush steppe
David A. Pyke
2002, Fact Sheet 126-02
Fire is a natural feature of sagebrush grasslands in the Great Basin. The invasion of exotic annual grasses, such as Bromus tectorum (cheatgrass), has changed the environment in these ecosystems. Invasive annual grasses provide a dense and continuous source of fuel that extends the season for fires and increases the...

Water Resources Division, U.S. Geological Survey
2002, Fact Sheet 126-01
Before 1800, the Missouri River was one of North America's most diverse and dynamic ecosystems. During the past 200 years, civil engineering has transformed it into a navigation system regulated by reservoirs and confined by bank stabilization and flood control structures. These modifications have reduced seasonal flow variability and sediment load...
