How much groundwater Did the US use each day in 1990?
Water withdrawals in the United States during 1990 were estimated to average 408,000 million gallons per day (Mgal/d) of freshwater and saline water for offstream uses–2 percent more than the 1985 estimate….Abstract.

How much groundwater does the US use per day?
The United States uses 82.3 billion gallons per day of fresh groundwater for public supply, private supply, irrigation, livestock, manufacturing, mining, thermoelectric power, and other purposes.
How has water use changed over the past 40 years?
Trends in total water withdrawals by category, 1950-2015 Electricity water use increased almost 400 percent from 1950 to 2005, but dropped about 19 percent from 2005 to 2015. Irrigation water use increased by about 29 percent since 1950—it takes more water to grow food for our increasing population.
How many gallons of water did we use in 2005?
Since 1950 the United States Geological Survey (USGS) has produced water use reports every five years to give a detailed look at how the United States uses water. The most recent USGS estimates show that in 2005 average water withdrawals was about 410 billion gallons per day (BGD) from fresh and salt water sources.
Where does the US get most of its water?
The top row of cylinders represents where America’s freshwater came from (source) in 2015, either from surface water (blue) or from groundwater (brown). You can see most of the water we use came from surface-water sources, such as rivers and lakes. About 26 percent of water used came from groundwater.
Will we run out of clean water?
While our planet as a whole may never run out of water, it’s important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world’s freshwater can be found in only six countries. Also, every drop of water that we use continues through the water cycle.
What percentage of water used in the US in 2005 came from groundwater?
You can see most of the water we use came from surface-water sources, such as rivers and lakes. About 26 percent of water used came from groundwater….

How much groundwater does the United States use?
Fresh groundwater irrigation withdrawals in these five States cumulatively accounted for 46 percent of the total fresh groundwater withdrawals for all categories nationwide. Nearly all groundwater withdrawals (97 percent) were from freshwater, predominantly used for irrigation.
How often is surface water used in the United States?
These water bodies supply the water to serve the needs of every human and for the world’s ecological systems, too. Here in the United States, every 5 years the U.S. Geological Survey (USGS) compiles county, state, and National water withdrawal and use data for a number of…
How old is the water in the ground?
Water at very shallow depths might be just a few hours old; at moderate depth, it may be 100 years old; and at great depth or after having flowed long distances from places of entry, water may be several thousands of years old. Ground water is stored in, and moves slowly through, moderately to highly permeable rocks called aquifers.
How often does the USGS collect water data?
Here in the United States, every 5 years the U.S. Geological Survey (USGS) compiles county, state, and National water withdrawal and use data for a number of… The freshwater in the Nation’s rivers, streams, creeks, lakes, reservoirs, and in underground aquifers are vitally important to our everyday life, and, indeed, to all life on Earth.
