Louisiana online water resources publications [More info]: Links to electronic publications on Louisiana water resources, some in PDF format, and link to bibliographies of electronic and paper publications.
Outdoor water use and water conservation opportunities in Virginia Beach, Virginia [More info]: How much water do you use to water your lawn, wash your car, or fill your swimming pool? Your answers to these questions have important implications for water supplies. A survey in this area showed the types of users and the ways in which water is used.
Phosphorus and groundwater: Establishing links between agricultural use and transport to streams [More info]: Explains why phosphorus is important, how it moves through the terrestrial water system, how we measure it, and what this means for people who need to manage or monitor human activities that produce it.
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in 2005 [More info]: Estimates the amount of several types of water (surface or groundwater, freshwater or saltwater) withdrawn for use in 2005, detailing the major activities for which the water was used.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.
