National Ground Water Awareness Week

National Ground Water Awareness Week

The National Groundwater Awareness Week is held in March of each year.

What is #GWAW?
#GWAW is an annual, weeklong observance established by NGWA to highlight the responsible development, management, and use of water. Established in 1999, #GWAW provides an opportunity for people to learn about the importance of groundwater and how the resource saves lives.

Who can participate?
Everyone! We encourage businesses, individuals, educators, students, federal agencies, cities, associations, your Aunt Martha, your mail carrier, and your pet fish to all join in.

What can my business or organization do to get involved with #GWAW?
Great question! The best answer is to use the resources on to spread the word. For example, fill in the press release and send to local media. Forward #GWAW social media tips to all your digital champions. Incorporate graphics and facts into various tweets and posts throughout the week. Additionally, we encourage you to share your story during the week using #GWAW or submitting it through the “share your story” link on When your team decides to get involved by visiting a local classroom to educate students on the importance of groundwater, take pictures and share them everywhere! Whatever you do, just have fun!

Why should I get involved?
Because groundwater literally makes life possible and we need to take collective steps to ensure the natural resource is both clean and available for generations to come.
