Coal resources, stratigraphy, geochemistry, coal quality and geology of coal in the Colorado Plateau, Arizona, New Mexico and Utah. Text in PDF format and available on CD-ROM.
Listing of USGS research and monitoring projects on mine drainage, in order to promote cooperation and collaboration among scientists working on problems related to mining and the environment.
Consistent, historic, and up-to-date ground-water data, such as water levels collected at wells and springs, are available from the USGS National Water Information System as graphs, tables, or files to download.
Consistent, historic, and up-to-date surface-water data, such as gage height (stage) and streamflow (discharge), collected at major rivers, lakes, and reservoirs, downloadable from the USGS National Water Information System as graphs, tables, or files.
Consistent, historic, and up-to-date water-quality data, such as temperature, specific conductance, pH, nutrients, pesticides, and volatile organic compounds downloadable from the USGS National Water Information System as graphs, tables, or files.
Consistent, real-time water data from streams, lakes, reservoirs, ground-water, and meteorological sites, are available from the USGS National Water Information System as graphs, tables, or files to download.
Study of the susceptibility and vulnerability of basin-fill aquifers in the region to ground-water contamination by synthesizing the information on ground-water quality conditions in 15 basins from previous studies.
Streamflow statistics and basin characteristics for most streams in specific US states using the Streamstats program. Data for areas can be selected from interactive maps and by an automated process. Includes a tutorial.
Change in streams accompanying land and water use may affect benthic invertebrate assemblage composition and structure through changes in density of invertebrates or taxa richness, the number of different species living in the stream.
