National Groundwater Awareness Week

National Groundwater Awareness Week is an annual observance that occurs during the month of March and is sponsored by the National Groundwater Association, or NGWA. Approximately 99% of the usable water in the world is groundwater, and in the United States, it’s used not only for the drinking water supply but also for agricultural irrigation.

Since water is one of the most precious resources in the world and people depend on it for day-to-day life, it’s important that groundwater supplies are adequately protected. And that’s exactly why people should take the time to observe this annual observance week.

Interesting Facts About Groundwater

Let’s dig into some facts about groundwater so that everyone can learn a little bit about it during National Groundwater Awareness Week. We’ve assembled the following facts for anyone and everyone interested in groundwater and how it should be protected.

  • The amount of groundwater is 30 times higher than all U.S. streams, rivers, and lakes combined.
  • Almost half of the U.S. population relies directly on groundwater for their drinking water supply.
