  • Only 1 percent of the water on Earth is useable, 99 percent of which is groundwater.
  • The United States uses 349 billion gallons of freshwater every day.
  • Groundwater is 20 to 30 times larger than all U.S. lakes, streams, and rivers combined.
  • Groundwater accounts for 33 percent of all the water used by U.S. municipalities.
  • 44 percent of the U.S. population depends on groundwater for its drinking water supply.
