      All States provided estimates for public supply, domestic, irrigation, livestock, aquaculture, industrial,mining, and thermoelectric power water use. All States also provided estimates of public supply deliveries for domestic use.All States will have estimates of the total population served by public supply. States optionally may have estimated public supply population served by groundwater and surface water.All States will have estimates of total irrigation. States optionally may have estimated subtotals for crop irrigation and golf-course irrigation.No consumptive-use data were collected nationally for any of the categories for 2010.No commercial water-use data were collected nationally for 2010.No wastewater release data were collected nationally for 2010.No hydroelectric power instream use data were collected nationally for 2010.Public-supply deliveries for commercial, industrial, and thermoelectric power were not collected nationally for 2010.

      These data files present water-use estimates by county for the United States, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands which support the State-level water-use estimates published in USGS Circular 1344, Estimated Use of Water in the United States in 2005 and 2010.

      This map displays over 1,500 mineral facilities in Africa and the Middle East. The mineral facilities include mines, plants, mills, or refineries of aluminum, cement, coal, copper, diamond, gold, iron and steel, nickel, platinum-group metals, salt, and silver, among others. The data used in this poster were compiled from multiple sources, including the 2004 USGS Minerals Yearbook (Africa and Middle East volume), Minerals Statistics and Information from the USGS Web site, and data collected by USGS minerals information country specialists. Data reflect the most recent published table of industry structure for each country. Other sources include statistical publications of individual countries, annual reports and press releases of operating companies, and trade journals. Due to the sensitivity of some energy commodity data, the quality of these data should be evaluated on a country-by-country basis. Additional information and explanation is available from the country specialists. See Table 1 for general information about each mineral facility site including country, location and facility name, facility type, latitude, longitude, mineral commodity, mining method, main operating company, status, capacity, and units.
