Thanks to to the National Groundwater Association we celebrate National Groundwater Awareness Week starting today.
Here are some groundwater facts from NGWA:
- The Oglalla Aquifer (aka High Plains Aquifer System) stretches more than 450,000 square kilometers (174,000 square miles) through the United States, including parts of South Dakota, Wyoming, Nebraska, Colorado, Kansas, New Mexico, Oklahoma, and Texas, according to National Geographic. The Oglalla Aquifer holds more than 3,000 cubic kilometers (2.4 billion acre-feet) of groundwater.
- The average household’s leaks can account for nearly 10,000 gallons of water wasted every year, according to the U.S. Environmental Protection Agency.
- Ten percent of homes have leaks that waste 90 gallons or more per day, according to the EPA.
- Of the estimated 29 billion gallons of water used daily by households in the United States, nearly 9 billion gallons, or 30 percent, is devoted to outdoor water use, according to EPA’s WaterSense program. In the hot summer months, or in dry climates, a household’s outdoor water use can be as high as 70 percent.
- 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, according to the U.S. Geological Survey
