Water is one of seven science mission areas of the U.S. Geological Survey (USGS). Water's mission is to collect and disseminate reliable, impartial, and timely information that is needed to understand the Nation's water resources.Read Science Plan
Geochemical models for the eastern Snake River Plain aquifer system are being used to better understand the flow of groundwater beneath the INL and, ultimately, to better understand the fate and transport of radiochemical and chemical constituents. As water moves through the ground, it picks up chemicals from the gases and rocks it comes in contact with.
As basaltic lava cools and hardens, the inclination, declination, and polarity of the Earth’s ambient magnetic field is recorded in the magnetic minerals of the rock. The recorded magnetic values are largely preserved and can be deciphered by paleomagnetic analysis.
We drill and maintain wells around the INL to monitor and sample groundwater, obtain basalt and sediment cores for study and analysis, and study the physical properties of the subsurface (geophysical logging).
This information helps us to improve the scientific understanding of the eastern Snake River Plain and its aquifer. In particular, we are examining the subsidence of the plain and...
Drillers use the vertical and horizontal views captured by our downhole video camera to examine borehole integrity before placing water well casing, well screens, and submersible pumps. Hydrologists and geologists use the images to verify geophysical data such as: changes in rock type, small-scale geologic structures, rock fractures, and groundwater movement.
Our scientists collect geophysical data from wells to understand the character of rocks and fluids below the surface. Geophysical data for a well are recorded, interpreted, and then disseminated as a geophysical log. Engineers and well drillers use geophysical logs to make well construction decisions such as design for well casing, well screen, and pump placement. Hydrologists, geologists and...
Since 1966, we have archived over 6000 samples of about 500 mL each of "raw" (unfiltered and unpreserved) water from groundwater and surface-water quality sites collected during our monitoring activities. Through the years, we've kept the water samples in a secure room and tracked which samples researchers have requested and analyzed for various projects.

Our Core Storage Library currently houses about 135,000 feet of core and several suites of cuttings from boreholes drilled at the INL. More cores and cuttings are added every year. The CSL also houses two suites of core and cuttings from the western Snake River Plain. In 2015, we added new core storage space in building CF 674.
Relatively little is known about the Yellowstone-Snake River "hotspot" system. To increase our knowledge, the U.S. Department of Energy’s Geothermal Technologies Program provided over $4.5 million of this $6.7 million project using American Recovery and Reinvestment Act funds.
The U.S. Department of Energy has proposed a location for a new facility to store waste at the INL. In the unlikely event that waste leaks from the facility, it will be important to monitor whether the contamination reaches the aquifer and baseline information is need before the facility is built.
Because we need to know how water and contaminants may travel through the aquifer, we need...
As part of the Comprehensive Environmental Response Compensation and Liability Act, it is important to evaluate the effect of Naval Reactors Facility (NRF) activities on the water quality of the eastern Snake River Plain aquifer.
Rapid population growth in the Wood River Valley since the 1970s has caused concern about the long-term sustainability of the groundwater resource. Water-resource planners and managers, as well as other decision makers, need a tool for water rights administration and water-resource management and planning.
Microplastics in the environment are of increasing concern among resource managers and ecologists. With global production of plastic topping 300 million metric tons in 2015, research in fresh and marine waters throughout the world has implicated urban runoff, wastewater treatment effluent, and litter breakdown as major sources of microbeads and synthetic pieces and fibers that are slow to...
The USGS collects, analyzes, and distributes data on a wide variety of water-related issues and resources. Much of our data is publicly available through the National Water Information System (NWIS), but additional datasets and analytical tools are also available.Access NWISWeb
The National Water Information System (NWIS) Mapper provides access to water-resources data at over 1.5 million sites across the U.S., including current and historical data. Users can search by site type, data type, site number, or place.
The National Water Census Data Portal contains national estimates of water budget components for local watersheds, water withdrawal data for counties, tools to calculate statistics of daily streamflow records, modeled daily streamflow at ungaged stations, and access to records of aquatic biology observations.
Data from wells, springs, test holes, tunnels, drains, and excavations in North Dakota; well location data includes information such as latitude and longitude, well depth, and aquifer. Groundwater level data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
The USGS operates a network of real-time water-quality monitoring stations that measure up to five physical parameters. The parameters are temperature, specific conductance, pH, dissolved oxygen, and turbidity. One to four of those parameters are measured at 26 sites, while all five parameters are measured at 13 sites.
Water-use data are collected by area type (state, county, watershed, or aquifer) and source (rivers or groundwater), and category (such as public supply or irrigation). Water-use data has been reported every five years since 1950. The USGS works with local, State, and Federal agencies as well as other organizations to collect and report withdrawals.
Aquatic invertebrates are a key component of freshwater ecosystems, and an understanding of aquatic invertebrate taxonomy is central to freshwater science. The North American Aquatic Macroinvertebrate Digital Reference Collection (NAAMDRC) was created by the USGS Aquatic Experimental Lab (AXL) to provide users with high-quality digital microscopy photographs.
A long-term study of the geomorphic history of the lower Rio Puerco arroyo in north-central New Mexico included the collection of high-precision (Real-time kinematic) GPS survey data (2002, 2007, 2010, and 2014), registration and rectification of historical aerial photographs (1935, 1950s, 1970s, and 1996), aerial LiDAR survey (2005) and post-flood (2006) satellite imagery.
Stream water-quality characteristics provide scientists and water managers with a better understanding of the effects of natural and anthropogenic (human) activities on streams and ecosystems. The USGS operates a network of near-real-time water-quality monitoring stations that provide data for temperature, specific conductance, pH, dissolved oxygen, and turbidity of surface water.

Water is one of the most important of Alabama's natural resources. Water is not only a vital component of human existence, it is critical to the overall quality of life. In order to protect and preserve this resource for future generations, we must have a baseline of information to make decisions.
The goals of the NAWQA program are being achieved through ongoing or planned investigations of 59 of the Nation's most important river and aquifer systems, which are referred to as study units. These study units were selected to represent the diverse geography, water resources, and land and water uses of the Nation. The Mobile River Basin is one such study unit, designed to supplement water.
