NWQP Research on Harmful Algal Blooms (HABs)
Harmful algal blooms (HABs) are caused by a complex set of physical, chemical, biological, hydrological, and meteorological conditions. Many unanswered questions remain about occurrence, environmental triggers for toxicity, and the ability to predict the timing, duration, and toxicity of HABs.
Trends in Water Use
Total withdrawals for all categories of use in 2015 were estimated to be 322 billion gallons per day (Bgal/d), a level of withdrawal not reported since before 1970. Total withdrawals in 2015 were 9 percent less than in 2010, continuing a sharp but steady downward trend since 2005. Freshwater withdrawals were also 9 percent less than in 2015.
Public Supply Water Use
Public supply refers to water withdrawn by public and private water suppliers that provide water to at least 25 people or have a minimum of 15 connections. Public-supply water is delivered to users for domestic, commercial, and industrial purposes. Part of the total is used for public services, such as public pools, parks, firefighting, water and wastewater treatment, and municipal buildings, and...
Irrigation Water Use
Irrigation water use includes water that is applied by an irrigation system to sustain plant growth in agricultural and horticultural practices. Irrigation also includes water that is used for pre-irrigation, frost protection, chemical application, weed control, field preparation, crop cooling, harvesting, dust suppression, and leaching salts from the root zone. Estimates of irrigation withdrawals...
Recreational Water Quality
People love to play in water. The USGS works to ensure that water in our nation’s streams, lakes, and oceans are suitable for the moments when you just need to jump in .
Coastal Carolinas Focus Area Study
The USGS is undertaking a 3-year study of water availability and use to investigate competing societal and ecological needs in Southeastern Atlantic Coastal Basins of the Carolinas. This study will compile existing information, add new scientific data and interpretation, and develop tools to help resource managers and stakeholders address current and future water-use challenges.
Upper Rio Grande Basin Focus Area Study
USGS is undertaking a 3-year study of water use, availability, and change in the Upper Rio Grande Basin. This study area runs 670 miles from its headwaters in Colorado through New Mexico and northern Mexico to Texas, and will compile existing information and add new scientific data and interpretation to help stakeholders face current and future water issues.
Urban Waters Federal Partnership—Bronx and Harlem River Watersheds (New York, N.Y.)
The Harlem and Bronx Rivers provide ecological and social resources in an intensively urban area. Connecting people to rivers requires clean water—the USGS is helping to assess the efficacy of green infrastructure to improve the quality of stormwater that flows into the rivers.
Urban Waters Federal Partnership—Middle Rio Grande (Albuquerque, N. Mex.)
The Valle de Oro National Wildlife Refuge, just 7 miles south of downtown Albuquerque on the Rio Grande, will reconnect people, especially young people, with nature in this highly populated area. The USGS is gathering data that will help gauge the success of habitat restoration efforts.
Urban Waters Federal Partnership—Little Calumet River (Northwest Indiana)
The USGS works with a wide range of cooperators to investigate many aspects of water quality. The newly integrated USGS Ohio-Kentucky-Indiana Water Science Center is assisting in furthering urban water-quality research in Northwest Indiana.
Urban Waters Federal Partnership—Middle Blue River Basin (Kansas City, Mo.)
Reconnecting people and water is an increasingly important goal in many urban areas. Parks, urban trails, boat ramps, and urban agriculture all are ways that an urban population can interact with nature and improve quality of life. USGS is participating in gathering the information that will make these projects possible.
Water Chemistry Data for Selected Springs, Geysers, and Streams in Yellowstone National Park, Wyoming, Beginning 2009
Results of water analyses conducted on numerous thermal and non-thermal features in Yellowstone National Park beginning in 2009. Water samples were collected and analyzed as part of research investigations on arsenic, iron, nitrogen, and sulfur redox species in hot springs and overflow drainages; the occurrence and distribution of dissolved mercury; and general hydrogeochemistry of hot springs.
