Did you know…? According to the USGS, the average person uses about 80-100 gallons of water per day. That figure coincides with the Environmental Protection Agency’s estimate that “The average American family of four uses 400 gallons of water per day.” Find out how much water is used for different purposes on the USGS Water Q&A page. Learn how to save some of that water on the EPA’s Water Sense page.
