Groundwater Awareness 

March 10 - 16, 2019 is the 20th Anniversary of National Groundwater Awareness Week. This year’s theme, "Think", was designed to urge each of us to consider various ways we can protect our most valuable natural resource. So Think about not running the water while you brush your teeth. Or Think about getting that leaking faucet fixed. Think about the farmers that rely on groundwater to grow the food we eat. And Think about having your well inspected to protect your drinking water system. In short, during #GWAW, Think about our future. 

US Groundwater Facts

  • Approximately 132 million Americans rely on groundwater for drinking water. It is used for irrigation, livestock, manufacturing, mining, thermoelectric power, and several additional purposes, making it one of the most widely used and valuable natural resources we have. Consider the following facts:
  • Americans use 79.6 billion gallons of groundwater each day.
  • Groundwater is 20 to 30 times larger than all U.S. lakes, streams, and rivers combined.
  • 44 percent of the U.S. population depends on groundwater for its drinking water supply.
  • More than 13.2 million households have their own well, representing 34 million people.
  • 99 percent of all available freshwater comes from aquifers underground.

Ohio Groundwater Facts

  • Approximately six and a half million (about 45% of) Ohioans rely on groundwater every day for their drinking water supply.
  • More than 600,000 households (approximately 1.45 million people), in Ohio, use groundwater from a well as their water supply.
  • 916 public water systems, in Ohio, receive water solely from groundwater resources which supply water to 2.88 million Ohioans.
  • 18 public water systems, in Ohio, receive water from both ground water and surface water and serve 3.3 million Ohioans, which includes Cincinnati, Dayton, and Columbus.
  • Lake Erie receives approximately 48% of its water from ground water discharge into the lake.  Eighty-nine (89) small and large community water systems, in the Lake Erie basin, obtain their water from Lake Erie and supply the water to approximately 2.8 million people.
