Facts About Fresh Water

Center pivot sprinklers in the High Plains – Ogallala Aquifer

  • An aquifer is a storage underground for water, which is where tap water comes from.
  • Of all of Earth’s water, about 98% of it is salt water, and about 2% is frozen. Therefore, only less than 1% of Earth’s water is liquid, fresh, and suitable for drinking.
  • Of all of Earth’s ground and surface water, about 99% of the water is from groundwater.
  • About 70% of Minnesotans drink groundwater instead of surface water.
  • The Ogallala aquifer in the High Plains has lost about 325,000,000,000 gallons of water every year for the past 40 years, which is about 13 TRILLION gallons used over the past four decades.
  • Groundwater from aquifers are normally clean and unpolluted depending on pore sizes of the rock sediment or soil that bears the water.
  • Sometimes aquifers can be polluted by chemicals in run-off such as road salt and fertilizers.
  • Aquifers are separated into two groups: replenishable, which can recharge relatively quickly, and nonreplenishable, which recharge normally over decades to centuries.
  • The average American household uses about 300 gallons of water per day.
  • About 80.1 gallons of water is used every day in the average American household by flushing toilets.
