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.
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.
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.
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.
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.
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.
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.
In 2005, about 15.8 million gallons per day (Mgal/d) of water were withdrawn, including 4.12 Mgal/d from groundwater and about 11.7 Mgal/d from surface-water sources.Public supply use accounted for about 78 percent (12.4 Mgal/d) of the total water withdra
