Provides standards and guidance for measuring, estimating, collecting, and analyzing water-use data. Includes brief descriptions of water-use activities, commonly used water-use terminology, and approaches and methods used in estimating water use.
Links to water use reports for the United States for 1985, 1990, and 1995 comparison of use and renewable water supply by region, handbook for collecting water-use data, and other information on national water use.
Drought water homepage with links to maps showing streamflow conditions, drought definitions, resources, publications, and answers to Frequently Asked Questions (FAQs).
General information on the science of hydrology with information on ground water, surface water, water use, the work of hydrologists, and hydrology as a career.
Describes and provides examples of impacts of human-induced land subsidence resulting from the extraction of subsurface water, including aquifer-system compaction, drainage of organic soils, dissolution and collapse of susceptible rocks.
Results (*.pdf) of a 1998 targeted reconnaissance survey on the sources of radium, polonium, and lead radionuclides, data collection and laboratory methods, existing occurrences in drinking water, risk assessments, and compliance monitoring.
Mathematical model of the groundwater system in this area includes 13 types of data and spans multiple aquifers over more than a century. This enables us to assess the quantity of groundwater, where and how it is being used, and how pumping affects it.
Modeling effort that integrates a wide variety of geographic, hydrologic, agricultural, climatic, and biological information to help local land managers address resource use issues.
Summarizes graphically the areas where water levels have dropped, and by how much, in this extensive underground water reservoir that covers several states in the mid-continent.
Water levels in wells completed in the Mississippi River Valley alluvial aquifer and the Sparta aquifer in eastern Arkansas respond to variability associated with annual precipitation.
Information from climate model forecasts, projections of future flows, paleoclimatic indicators, timing of snowmelt, airborne dust, and the effects on vegetation of troublesome pest species indicate the nature and severity of problems looming.
Study of the effects of the practice of cycling municipal nutrient-enriched wastewater from holding ponds through forested wetlands. Studies were in the Cypiere Perdue Swamp, Louisiana, and the Drummond Bog, Wisconsin.
Freshwater withdrawal estimates for Oklahoma by source and category. Withdrawal data from ground water and surface water for domestic, commercial and agricultural use.
Information about basin storage, historical changes, and consumptive water use for manages and planners to use to develop policies for efficient and sustainable water use.
The U.S. ground water atlas consists of information on ground water resources of 13 regions covering the 50 States, Puerto Rico, and the U.S. Virgin Islands. Text and maps can be viewed online and downloaded as ASCII, GIF, and *.eps files.
Report examines what is known about the Nation's ground-water availability, and outlines a program of study to improve our understanding of ground-water availability in major aquifers across the Nation. With regional examples.
National Water Information System (NWIS) real-time data on selected ground water sites, ground water level data, site inventory of wells, test holes, drains, springs and excavations and ground water-quality data for the United States.
Process and plan to be used to provide reliable evaluations of the potential effects of groundwater production and help guide sustainable management of the resource.
Research findings and examples of application to real problems--biosolids have high concentrations of household contaminants compared to treated liquid wastewater effluent.
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.
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.
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.
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.
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.
