USGS provides science about the natural hazards that threaten lives and livelihoods; the water, energy, minerals, and other natural resources we rely on; the health of our ecosystems and environment; and the impacts of climate and land-use change. Our scientists develop new methods and tools to supply timely, relevant, and useful information about the Earth and its processes.

- USGS Geochemical Database for the Brackish Groundwater Assessment of the United States - Dissolved SolidsBrackish groundwater (BGW), defined for this assessment as having a dissolved-solids concentration between 1,000 and 10,000 milligrams per liter is an unconventional source of water that may offer a partial solution to current (2016) and future water challenges. In support of the National Water Census, the U.S. Geological Survey has completed a BGW assessment to gain a better understanding of the occurrence and character of BGW resources of the United States as an alternative source of water. Analyses completed as part of this assessment relied on previously collected data from multiple sources, and no new data were collected. One of the most important contributions of this assessment is the creation of a database containing chemical data and aquifer information for the known quantities of BGW in the United States. Data were compiled from single publications to large datasets and from local studies to national assessments, and includes chemical data on the concentrations of dissolved solids, major ions, trace elements, nutrients, radionuclides, and physical properties of the resource (pH, temperature, specific conductance). This dataset represents major-ions data from a compilation of water-quality samples from 33 sources for almost 384,000 groundwater wells across the continental U.S., Alaska, Hawaii, Puerto Rico, the U.S. Virgin Islands, Guam, and American Samoa. The data are published here as an ESRI geodatabase with a point feature class, and associated attribute table, and also as non-proprietary comma-separated value table. Dissolved-solids data include information for assessing the distribution of dissolved-solids concentrations and other chemical constituents that may limit the usability of brackish groundwater. It was not possible to compile all data available for the Nation, and data selected for this investigation were mostly limited to larger datasets that were available in a digital format. As a result, some data on a more local-scale may not be included.1Licence not specifiedabout 1 year ago
- USGS National Ground-Water Monitoring NetworkThe NGWMN Data Portal provides access to groundwater data from multiple, dispersed databases in a web-based mapping application. The portal contains current and historical data including water levels, water quality, lithology, and well construction. The NGWMN is currently in the process of adding new data providers to the Network. Agencies or organizations collecting groundwater data can find out more about becoming a data provider for the Network. Funding to support data providers to the National Ground-Water Monitoring Network is provided through USGS Cooperative Agreements. Agencies can also find information about the status of the USGS cooperative agreements.1Licence not specifiedabout 1 year ago
- USGS REST Web ServicesREST is a "URL friendly" way to retrieve data (generally in an XML format) over the web. This service lets you acquire near real-time water data from thousands of sites managed or monitored by the USGS across the country. Readings are usually made every 15 minutes and transmitted hourly. Data is currently available since October 1, 2007. Note: certain operational data is typically restricted to 120 days. A number of flexible filters allow you to find data about sites of common interest easily. Call 1-888-275-8747 for questions.1Licence not specifiedabout 1 year ago
- USGS National Produced Waters Geochemical Database v2.3During hydrocarbon production, water is typically co-produced from the geologic formations producing oil and gas. Understanding the composition of these produced waters is important to help investigate the regional hydrogeology, the source of the water, the efficacy of water treatment and disposal plans, potential economic benefits of mineral commodities in the fluids, and the safety of potential sources of drinking or agricultural water. The U.S. Geological Survey National Produced Waters Geochemical Database v2.3 is an updated compilation of geochemical and related information for water from oil and gas wells in the United States. It includes identification and location information, well descriptions, dates, rock properties, physical properties of the water, inorganic chemistry, organic chemistry, and isotopes.1Licence not specifiedabout 1 year ago

- USGS Real Time Water Data for New MexicoUSGS Real Time Water Data for New Mexico includes streamflow, groundwater, lake and reservoir, precipitation, and water quality data. Real-time data typically are recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used.1Licence not specifiedabout 1 year ago
- USGS WaterAlertReal-time data from USGS monitoring locations are transmitted via satellite or other telemetry to USGS offices at various intervals; in most cases, once every hour. Emergency transmissions, such as during floods, may be more frequent. Notifications will be based on the data received at these site-dependent intervals. Read our Check Status User blog post to get an idea of common use cases for WaterAlert. The development and maintenance of the WaterAlert system is supported by the USGS and its partners, including numerous federal, state, and local agencies.1Licence not specifiedabout 1 year ago

This dataset represents major-ions data from a compilation of water-quality samples from 16 sources for about 124,000 groundwater wells across the continental U.S., Alaska, Hawaii, Puerto Rico, the U.S. Virgin Islands, Guam, and American Samoa. The data are published here as an ESRI geodatabase with a point feature class, and associated attribute table, and also as non-proprietary comma-separated value table. Major-ions data include information for assessing the geochemical-water type, saturation indices, and potential for mineral scaling. It was not possible to compile all data available for the Nation, and data selected for this investigation were mostly limited to larger datasets that were available in a digital format.
