A tile map of the U.S. with alluvial charts for each state and the nation that show changes in the total volume of water use from 1985-2015 across eight categories (thermoelectric, irrigation, public supply, industrial, aquaculture, mining, domestic, and livestock).
How much water is used by people in the United States?
Since 1950, the USGS has collected and analyzed water-use data for the United States and its Territories. That data is revised every 5 years.
As of 2015, the United States uses 322 billion gallons of water per day (Bgal/day). The three largest water-use categories were irrigation (118 Bgal/day), thermoelectric power (133 Bgal/day), and public supply (39 Bgal/day), cumulatively accounting for 90 percent of the national total.

In 2015, water use in the U.S. totaled 322 billion gallons/day. Total water use is broken out into 8 categories using different colors.

The quality of the water we drink can potentially impact our health. The USGS has several programs and cooperative projects that characterize the quality of selected rivers and aquifers used as sources of drinking water to community water systems in the United States.
