Water supply and demand
The quantities of water resources in an area that are easily available and the amount of water that is needed for all uses.
Possible effects of groundwater pumping on surface water in the Verde Valley, Arizona [ More info] We applied a groundwater model to simulate effects of groundwater pumping and artificial recharge on surface water in this area. Results show effects of pumping or recharge on streamflow.
Quantifying effects of climate change on the snowmelt-dominated groundwater resources of northern New England [ More info] Planned analysis of the sensitivity of groundwater levels to changes in air temperature and precipitation. Changes in groundwater recharge and discharge also will be correlated with other hydrologic indicators.
Science to support the understanding of Ohio's water resources [ More info] Short descriptions of a variety of ongoing USGS studies focused on water resources in Ohio.
Source Water-Quality Assessment [ More info] Characterize the quality of selected rivers and aquifers used as a source of supply to community water systems in the United States to determine the occurrence of about 280 primary unregulated anthropogenic organic compounds.
Source, Use, and Disposition of Freshwater in Puerto Rico, 2005 [ More info] Quantitative analysis of water use statistics for Puerto Rico, showing domestic, agricultural, industrial, and electric power as the main offstream uses.
Summary of estimated water use in the United States in 2005 [ More info] Estimates the amount of several types of water (surface or groundwater, freshwater or saltwater) withdrawn for use in 2005, detailing the major activities for which the water was used.
Sustainability of Water Resources in the Fractured-Rock Area of Maryland [ More info] Explains why a water resource assessment for the area west of the Fall Line is needed.
Wastewater Indicators Shown to Degrade in Streams [ More info] Research findings and examples of application to real problems--the stability of contaminants that indicate human wastewater needs to be considered.
Water resources [ More info] Hydrologic and water-quality information with access to water data, publications, and maps, as well as to recent water projects and events.
Water resources data for Washington [ More info] Access to data on water resources of Washington including surface water, ground water, water quality, water use, GIS, and biological datasets and access to reports.
