Freshwater Use and Source in the US
America's
water source in 2000 was either from surface water or from ground water. Most of the water we use (262,000
million gallons per day (Mgal/d)) came from surface-water sources,
such as rivers and lakes. We used about 83,400 Mgal/d of ground water
(from wells).
 LEVEL ONE: Sources of fresh water. LEVEL TWO: Shows where the water was sent after
being withdrawn from a river, well, etc. LEVEL THREE: Each green cylinder represents a category of water use.
Here's how to read the chart: In 2000, about 18,500
Mgal/d of water was used for industrial purposes, with about 14,900
Mgal/d coming from surface water and about 3,570 Mgal/ coming from
ground water.
