Colgate’s #EveryDropCounts campaign (Colgate.com/everydropcounts) points out that:
- Brushing teeth with faucet running waste up to 4 gallons water.
- Turning off faucet saves up to 2,920 gallons water per year.
- If every American family pledges to turn off the water while brushing teeth, 10 trillion glasses of water per year would be saved.
- One in 10 people worldwide lack access to clean water – almost twice the population of the US.
The US EPA describes how little of the water on Earth is actually available for drinking. Of all the water on Earth, "less than 1 percent is available for human use. The rest is either salt water found in oceans, fresh water frozen in the polar ice caps, or too inaccessible for practical usage. While population and demand on freshwater resources are increasing, supply will always remain constant. And although it's true that the water cycle continuously returns water to Earth, it is not always returned to the same place, or in the same quantity and quality."
The EPA goes on to describe how overuse of fresh water affects the environment: "Less water going down the drain means more water available in the lakes, rivers and streams that we use for recreation and wildlife uses to survive. Using water more efficiently helps maintain supplies at safe levels, protecting human health and the environment."
