America’s rivers and streams are generally suitable for irrigation, supplying drinking water, and home and recreational uses. However, in areas with significant agricultural and urban development, the quality of our nation’s water resources has been degraded by contaminants such as pesticides, nutrients, and gasoline-related compounds.

Not long ago, conventional wisdom was that you couldn’t predict the climate for more than a few days in advance. Then came the awareness of El Niño and La Niña and the forecast window increased to as much as 6 to 9 months, depending on the region and season.

The USGS has just completed an assessment of undiscovered, technically recoverable oil and natural gas resources in five geologic basins in the Rocky Mountain region. The assessed basins are: Uinta-Piceance of Colorado and Utah, Southwestern Wyoming (Greater Green River Basin), San Juan Basin of New Mexico and Colorado, Montana Thrust Belt, and the Powder River Basin of Wyoming and Montana.

Federal, state and local policy makers will gather in Casper, Wyoming, on May 9-10 to examine science issues associated with the development of coalbed methane. The two-day conference and field trip, sponsored by the U.S. Geological Survey (USGS), will examine a number of topics including: what is coalbed methane, how it forms, where it occurs, how it is developed, and consequences of development.
