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.
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.
Drought water homepage with links to maps showing streamflow conditions, drought definitions, resources, publications, and answers to Frequently Asked Questions (FAQs).
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.
Studies in Eastern United States on massive sulfide deposits in Maine, Vermont, Great Smoky Mountains, and Virginia to assess potential environmental impacts.
Freshwater withdrawal estimates for Oklahoma by source and category. Withdrawal data from ground water and surface water for domestic, commercial and agricultural use.
Constructed farm ponds represent significant breeding, rearing, and overwintering habitat for amphibians in the Driftless Area Ecoregion of Minnesota, Wisconsin, and Iowa. Links to fact sheet, brochure, annual reports, field manual, and final report.
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.
Research findings and examples of application to real problems--biosolids have high concentrations of household contaminants compared to treated liquid wastewater effluent.
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.
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.
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.
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.
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.
Quantitative analysis of water use statistics for Puerto Rico, showing domestic, agricultural, industrial, and electric power as the main offstream uses.
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.
Explains 16 distinct types of scientific information that are needed to understand climate change, including the specific parameters measured, why they are needed, who measures them, and the type and amount of information that are not yet available.
Describes cooperation of the USGS office in Las Vegas, Nevada, with the Department of Energy to address environmental and scientific issues at the Nevada Test Site and vicinity with links to project information.
Hydrologic data web page for the Water Resources Inventory Area 1 (WRIA 1) Watershed Management Project studying surface and ground water in the Nooksack watershed in northwest Washington. Links to environmental data and maps.
In 2005, about 30.6 million gallons per day (Mgal/d) of water was withdrawn here, including about 30.4 Mgal/d from groundwater and 0.1 Mgal/d from surface water. Industrial use, primarily for wood products, accounted for about 72 percent (22 Mgal/d).
In 2005, about 72.9 million gallons per day (Mgal/d) of water were withdrawn here, including about 7.70 Mgal/d from groundwater sources and 65.2 Mgal/d from surface-water sources. Public-supply use accounted for about 71%, and power generation 19%.
Summarizes information on the water resources of Lafayette Parish, Louisiana. Information on groundwater and surface-water availability, quality, development, use, and trends is based on previously published reports.
Estimated using data obtained from various Federal and State agencies and local sources. Total consumptive water use also was estimated for each county in Georgia for 2005.
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.
In 2005, about 29.2 million gallons per day (Mgal/d) of water were withdrawn here, including about 26.8 Mgal/d from groundwater sources and 2.45 Mgal/d from surface-water sources. Rice irrigation accounted for 74 percent (21.7 Mgal/d) of the total.
